DE102007010933A1 - Threshing machine for grain harvests, and especially hemp, drops the harvest by gravity on to the threshing drums with an additional upward pulsation to detach the grains - Google Patents

Abstract

The threshing machine for grain harvests, especially hemp, has a feed to move the harvest to fall by gravity (S) over at least one threshing unit (104). The movement of at least one threshing unit gives a repeat pulse beating action on the harvest. At least one threshing unit has a threshing drum (8) rotating around an axis and with a pulsator (22) to deliver an additional pulse on the harvest on the drum against the direction of gravity.

Description

The Invention relates first a device for threshing grain-containing crop, which the device in Erntegutflußrichtung happens, in particular a device for threshing hemp, with one in crop flow direction forward feeding device, which feeds the crop of a threshing device, the release of the Grains out the crop is used and at least one movable in movement threshing organ includes, which is involved in the expression of the grains.

The Device is hereinafter exclusively using the example of Ausdrusches explained by hemp. However, it also realizes its advantages with other threshable ones Crops.

hemp places special demands on the mechanical harvest, in particular, as an economic Hemp cultivation not only from the use of fiber components of the plant but increasingly also of the grain use depends.

So far Essentially, two harvesting procedures have become established. At a The first harvesting methods are the plants with a total height of up to mowed to four meters and filed in the field in the swath. This is followed by the so-called field roast at which the hemp plants dry off and the fibers to get rid of the cockroaches kick off. For a uniform drying to reach the swaths are turned from time to time if necessary. While the field roast the grains mature to. Finally the hemp is pressed into bales and transported away for fiber production.

Around To make the hemp manageable, one has gone over to the plants shorten about 50 cm to 100 cm.

The grains harvest So far, however, it has not been satisfactorily resolved. A major problem represents the degree of ripeness of the cannabis seeds. The currently widespread Hemp varieties do not ripen evenly. Usually indicates the inflorescence the hemp plant has mature, less or immature seeds and possibly also still flowers on.

Should the grains be used in the above-described harvesting the Swath usually from a combine harvester taken and guided by its threshing. This has the advantage that evenly mature grains can be threshed. The disadvantage, however, is that due to the plant mass blockages The machine organs are only preventable if tight harvesting conditions can be complied with. Also, the not aligned to the Hanfernte machine organs heavily loaded, resulting in increased Wear and tear Failure leads. For this reason, the area services are low. Alternatively, the salvaged hemp bales are dissolved and one stationary Threshing device supplied, but what a reduction in quality of the Ausdrusches result.

at a second harvesting process leaves Hemp also cut and thresh directly. For this the company has Deutz-Fahr harvesting systems (Lauingen) in cooperation with the Gerhard Gotz GmbH (Buhl) and the state institute for Pflanzenbau Forchheim (FAP) a conventional harvester provided with a modified divider. Go through the hemp plants the threshing, where the threshed grains from the rest of the ducklings be separated. Subsequently However, a costly and costly drying of Ausdrusches is necessary.

Conventional Threshing continues to have the significant disadvantage that they optimized for harvesting grain. They rub grains between a threshing drum and a concave out of the inflorescences. Hemp seeds are quite sensitive due to their high oil content and burst easily within a conventional threshing unit on. this leads to to not insignificant crop losses and to a reduction in quality the expression.

task The invention therefore is to provide a device which meets the requirements of Hanfernte.

The Task is solved of a device having the features of claim 1, in particular with the characterizing features, according to which the crop in the direction of gravity is guided above the at least one threshing organ and that at least a threshing member under execution his movement essentially repeats an impulse the direction of gravity on the crop.

Instead of the crop by a conventional cereal threshing between Drum and concave guide and the grains by rubbing out of the inflorescences Separate, the crop is over a threshing device guided, which is easily dissolving grains shaking out of the inflorescences by Repeats an impulse on the hemp plants passing through the threshing machine is exercised. The invention thus makes a simple but effective way the loose fit of hemp seeds in the inflorescences to use.

A particularly preferred embodiment is characterized in that the at least one threshing element is designed as a threshing drum mounted so as to rotate about an axis, which has little least one active element, which repeatedly exerts a pulse substantially against the direction of gravity on the guided above the threshing drum crop, in particular, if the at least one threshing at least one above the threshing device passing crop arranged Gegendreschorgan is assigned, which repeatedly and alternately with the Dreschorgan exerts a counter-pulse on the crop, wherein the at least one counter thrust member may be formed as a rotating axis mounted around a counter drum, which has at least one reaction device that can repeatedly exert a pulse substantially in the direction of gravity on the guided below the counter drum drum crop.

through Momentum and counterpulse, the crop is set in strong motion, so that in addition to the release the hemp grains The crop is also loosened, making the hemp grains light fall through between the hemp plants.

This let yourself continue to improve when in Erntegutflußrichtung several threshing and / or Gegenreschorgane arranged one behind the other, these being designed as threshing and / or counter drum, several circumferentially offset arranged active organs can have and the active organ should be designed as axially parallel sheet metal, of which the drum axis opposite End region is directed against the direction of rotation.

at this embodiment goes through the invention the crop is a kind of "Rüttelstrecke", the orientation prevent the end regions of the active organs catching the crop, by promoting a sliding off of the active organs on the crop. The practice Active and counteractive organs impulses on the crop.

Around to promote the loosening of the crop, it is provided that the threshing and / or Counter drum at least one arranged in the drum circumferential direction Have crop part-part, in particular, if the crop part organ at least partially from the outer circumference the drum up to the end portion facing away from the circumference of the crop sub-organ is formed tapered and the axis-parallel end portions the conically tapered portions of the crop sub-organ substantially can be sharp-edged.

The thus formed crop sub-organs separate the threshing device continuous wedge swath wedge-like and reinforce that Fluffing. Due to the resulting gaps, the cannabis seeds can easily turn off fall out of the crop. In a wedge-shaped sharp-edged training the crop sub-organs serve selbige same promotion of the crop by the threshing organ.

Farther It is conceivable that threshing drum and / or counter drum in a Angle α smaller 90 ° to the Erntegutflußrichtung are aligned, with threshing drum and counter drum axis parallel can be aligned with each other and threshing and / or countershaft engaging in the crop and the crop by the threshing moving traction should have.

at oriented substantially in Erntegutflußrichtung Hemp plants set from 90 ° angle Deviating drums ensure that the crop promoting Do not submerge organs of the drums ineffective through the crop.

In a further embodiment is provided that the peripheral speed of each rotating Dresch- or counter drum higher is as the one in Erntegutflußrichtung upstream threshing or counter drum, this being achieved can be that the diameter of each threshing or counter drum is larger as the diameter of the threshing upstream in Erntegutflußrichtung Counter drum, creating a safe, jam-free transport of the crop ensured by the threshing organ is.

Around a smooth passage of the crop through the threshing regardless of to ensure that the plant mass varies within a stock, is provided that the distance between threshing and counter drum is variable.

Around To avoid being affected by the impulses and counter impulses wave-like or oscillating movement of the threshing device continuous crop in the direction in Erntegutflussrichtung before the Threshing device arranged organs of a harvester continues, is provided that between feeder and threshing organ a gap-forming mouth organ is arranged through the gap, the crop is guided, in particular, that the muzzle organ of at least two on top of each other mounted rollers is formed.

The The invention further relates to a method for threshing granular material Crop, in particular for threshing hemp, in which the crop fed to a threshing device becomes.

The Disadvantages of the known methods for threshing hemp are already described previously.

the inventive method is therefore the basis of the aforementioned task.

• – Fördern des Erntegutes durch die Drescheinrichtung hindurch,
• – wiederholtes Ausüben eines Impulses auf das Erntegut innerhalb der Drescheinrichtung,
• – Auflockern des Erntegutes,
• – Sammeln des sich mittels Impulsen vom Erntgut lösenden Ausdrusches.

The object is achieved by a method according to claim 32, which is characterized by the following method steps:

• Conveying the crop through the threshing device,
• Repeatedly applying a pulse to the crop within the threshing device,
• - loosening the crop,
• - collecting the expressions dissolving by means of pulses from the crop.

Instead of of the prior art abrasive rubbing of Hemp, the inventive method makes the loose fit of the Hemp seeds in inflorescences too Use. The cannabis seeds are processed according to this procedure the repeated exercise shaken out of pulses from the inflorescences. through of the procedure become the hemp grains very gentle threshing, which minimizes crop losses significantly.

Further Device and process configurations and their advantages from further subclaims and the following description of the drawing. It shows:

5 and 6 schematic partial views of alternative separating and cleaning devices and,

7 Representation of an alternative threshing device.

In 1 is a longitudinal section through a self-propelled harvester 100 shown for threshing in particular hemp. In the present illustration is the harvester 100 with a zinc drum 1 provided, which is also referred to as a pickup. By means of the zinc drum 1 be previously mowed and optionally shortened to a length of about 60 cm to 100 cm, in a swath 101 discarded hemp plants of an auger 2 fed. The auger 2 leads the swath 101 as an inclined conveyor 3 trained feeder and possibly reduces the swath width. It performs essentially the same function as a cereal combine.

Then this gets in the swath 101 deposited crop to the feeder, which in 2 is shown in more detail and in its entirety by the reference numeral 102 is provided. In the present case, the inclined conveyor comprises two conveyor belts arranged vertically one above the other 3 and 4 where the crop is between the lower conveyor belt 3 and the upper conveyor belt 4 is passed.

At the feederhouse of the threshing closes 104 upstream and in 3 Mouth organ shown in detail 103 at. The mouth organ 103 includes a first pair of rollers with the rollers 5 and 6 and a second pair of rollers with the rollers 7 and 9 ,

Behind the mouth organ 103 is then the threshing device 104 arranged. In the present exemplary embodiment, it comprises a plurality of threshing members in the form of four threshing drums which are rotatably mounted successively about an axis 8th and four counter drums arranged in the direction of gravity S above 10 ,

Part of the threshing device 104 are still several separating drums 12 , by means of which the Hanfschwad 101 is loosened. Together with the cleaning fan 11 , the lamellar sieve 14 , the second screening stage 15 and below the separating drums 12 arranged conveyor belt 16 These form the cleaning and separating device.

About the grain slug 13 gets the doom, so the crop by means of the threshing 104 separated hemp grains over the grain elevator 17 in the bunker 19 , over the bunker slug 18 For example, it can be emptied onto a loader wagon. The hemp straw that makes up most of the crop is removed from the harvester following the cleaning and separating device 100 pushed out.

Seen in Erntegutflussrichtung E are the assemblies zinc drum 1 , Auger 2 , Inclined conveyor 102 , Muzzle organ 103 , and threshing device 104 behind each other.

2 shows one opposite 1 enlarged view of the feederhouse 102 , next to the upstream auger 2 and the downstream orifice organ 103 ,

To hemp the threshing device 104 be fed to the feederhouse 102 Customized claims made. The comparatively rigid stems of the hemp plant tend to become threshing during transport 104 in the organs of conventional inclined conveyors 102 to catch. Therefore, the present feederhouse 102 with the lower conveyor belt 3 a column-free conveyor organ. Certain gap widths, however, are harmless. A substantially gap-free conveying member, such as, for example, closely arranged conveying rollers, is therefore suitable.

To ensure the safe transport of the crop, it is advantageous to hemp swath 101 pressure loaded by the feederhouse 102 To guide to a minimum of frictional engagement between the lower conveyor belt 3 and the swath 101 to ensure. This pressure load can be achieved in the simplest case by means of a vertically movable, a certain own weight having cover. However, a device which allows a targeted pressure control, for example by means of adjustable hydraulic cylinders, is advantageous. It is still, how 2 shows, advantageously an at least passively running or actively driven second conveyor belt 4 provided. Alternatively, another, substantially gap-free conveyor is also suitable here.

3 schematically shows the arrangement of the mouth organ 103 and the threshing device 104 with their as threshing drums 8th and counter drums 10 trained Dreschorganen and subsequent Separiertrommeln 12 ,

The mouth organ 103 is one the implementation of hemp swath 101 enabling, gap-forming organ, which has the task to calm the caused by the threshing organs wave motion of the hemp swath in Erntegutflussrichtung forward.

In the embodiment of 3 becomes the muzzle organ 103 from successively arranged roller pairs 5 / 6 . 7 / 9 and 20 / 21 educated. It makes sense if at least some of these rolls 5 . 6 . 7 . 9 . 20 and 21 are actively driven and also serve to advance the hemp swath to threshing. From the drawing it can be seen that the rollers of the mouth organ can be provided with various, not further described here in their function means which can serve an improved feed and / or the support of the Ausdrusches of the crop.

The roller pairs 5 / 6 . 7 / 9 and 20 / 21 form a mouth gap, the hemp swath 101 passes through. It is advantageous if the pairs of rollers 5 / 6 . 7 / 9 and 20 / 21 the hemp swath 101 pinch between them with a certain force. For this purpose, a device, not shown, for applying a predefined clamping force is provided which uses, for example, one or more hydraulic cylinders.

With the reference number 104 is the mouth organ 103 subordinate threshing called. In the present case, this consists of a number of threshing drums arranged below the crop 8th and corresponding, above the crop arranged counter drums 10 , These are arranged circumferentially offset active organs 22 Mistake. The drum 8th and 10 are on a vertical axis of paper plane arranged 25 stored and are set in a manner not shown by a chain or other drive in rotation.

The active organs 22 are formed as sheets, the circumferentially offset and parallel to the drum axis 25 on the drum 8th . 10 are attached. The drum shell surface 23 remote end regions 24 the active organs 22 are directed against the drum rotation direction to engage the active organs 22 into the crop and thus a hooking of plant parts with the active organs 22 to avoid.

The active organs 22 engage with rotation of the drums 8th and 10 into the Erntegutstrom and exert on this at regular intervals a pulse or blow. Here are the active organs 22 from threshing drum 8th and associated counter drum 10 positioned so that each impulse of the threshing drum 8th a counterpulse of the associated counter drum 10 follows. Figuratively speaking, the active organs 22 from threshing drum 8th and associated counter drum 10 roughly like two gears.

As impulse and counterpulse, the following process is understood in the embodiment illustrated here:
The active organ 22 dives by turning the drum 8th . 10 through the trajectory of Hanfschwads 101 through and displaces the crop. The crop experiences a positive (impulse) or negative (counter impulse) acceleration.

As a result of the repeated applied to the crop pulses this is within the threshing 104 put into a strong oscillating or wave-like movement, so that the hemp grains which are easily dissolved from the inflorescences are shaken out of the crop.

As already mentioned, the mouth organ serves 103 to prevent the oscillating movement from moving forward against the direction of crop flow and from promoting the hemp swath 101 to the threshing device 104 with special needs.

The active organs 22 or the drums 8th . 10 have drivers not shown here, which engage in the Erntegutstrom and move the crop further in Erntegutflussrichtung E. Furthermore, it is advantageous if the drums 8th . 10 are changeable in their orientation to crop flow, so that they can take an angle <90 ° to the crop flow. This prevents in predominantly in Erntegutflussrichtung E aligned plant components an ineffective dipping the driver.

Instead of in the embodiment vertically stacked drums 8th . 10 can the counter drums 10 also offset to the respective corresponding threshing drum 8th be arranged. Target of the arrangement of corresponding threshing and counter drums 8th . 10 is primarily the regular exercise of a pulse and Gegenimpulses.

Subordinate to the threshing organs are a plurality of separating drums arranged below the crop stream 12 , These can be essentially identical to the threshing drums 8th or counter drums 10 , In particular, these separating drums also have active organs 22 on, which exert a counter to the gravitational impulse to the crop. They essentially serve to loosen up the hemp swath 101 so that the hemp grains fall through the crop and into the effective range of the cleaning blower 11 reach.

4 shows a detailed view of a separating drum 12 , but also in this form as a threshing drum 8th and counter drum 10 can be used.

The separating drum 12 has a drum axis 25 on which they rotatable in the threshing device 104 is stored. Achsparallel and circumferentially offset are trained as sheets active organs 22 on the lateral surface 23 the drum 12 arranged. As already described, the end areas 24 the active organs 22 contrary to the feed of the crop within the threshing device 104 directed rotating direction.

Oriented in the circumferential direction are several stabilizing sheets 26 on the lateral surface 23 attached to the active organs 22 support each other. The stabilizing sheets 26 At the same time, they serve as a crop sub-organ by intervening in the crop and the Sharp plant parts substantially transverse to Erntegutflussrichtung split from each other and in this way the hemp swath 101 loosen.

To the dividing effect of the stabilizing sheets 26 to improve, these are partially with paraxial, from the drum shell surface 23 to the drum shell surface 23 remote end areas 27 the stabilizing sheets 26 tapered spreader plates 28 Mistake. These can be on one or both sides of the stabilizing sheets 26 , be aligned or circumferentially offset from each other. In this way, a wedge-like crop part organ is formed. The sharp, aligned substantially transversely to Erntegutflussrichtung edges of Spreizbleche 28 At the same time, they act as drivers because they engage the crop and when the drum rotates 12 cause a feed of the crop.

The separating and cleaning device of the threshing device 104 initially comprises a number of separating drums arranged one behind the other 12 , the same as the threshing and counter drums 8th . 10 can be trained. The active organs 22 practice, just like the organs of action 22 the threshing drums 8th , an impulse against the direction of gravity on the crop. This is how Hanfschwad becomes 101 shaken out hemp grains from the crop.

The crop sub-organs loosen the crop further, so that the hemp grains through the hemp swath 101 through to the drums 12 arranged cleaning screens 14 . 15 and in the area of the cleaning blower 11 reach. In the Erntegutflussrichtung E rear area of the separating device is instead of sieves a conveyor belt 16 , which is the one from the Hanfschwad 101 falling expressions the seven 14 . 15 supplies.

In the 5 and 6 are alternative arrangements of the drums 12 the separating and cleaning device shown. In 5 are the separating drums 12 grouped into groups that are each tiltable with respect to the Erntegutstromes. In this way, in each case a shoulder or a step forms in the transition between two drum groups, which supports the separation and loosening process.

In 6 is in each case between two separating drums 12 a separating roller 29 rotatably mounted, the smaller in circumference than the separating drums 12 is trained. This construction leads to a wave-like movement of the hemp swath 101 , which over the outer peripheral surfaces of the drums 12 and rolling 29 to be led. This movement also supports the loosening of the crop and the separation of hemp grains from the plant components.

Instead of or in addition or in alternation with the separating drums 12 the cleaning and separating can also conventional hordes shakers or sieve belts.

In 7 is an alternative threshing device 105 shown. It includes a feeder 30 which is also designed here as an inclined conveyor. This feederhouse 30 is characterized by the fact that the conveyor organ, here a conveyor belt 31 is arranged above the Erntegutstromes and tine or web-like driver 32 having. The channel-like feeder 30 has a simple sheet metal on the bottom side 34 on, over which the crop by means of the conveyor belt 31 is pulled.

A mouth area 33 downstream of the feederhouse, there is already described above threshing drum 8th that also like here in 4 Separating drum shown in detail 12 can be designed.

Near the mouth area has the bottom plate 34 a joint 35 on which a crop guide plate 36 is pivotally mounted. The crop guide plate 36 guides the plant material to just before the threshing drum 8th into the area of their organs of action 22 , In the present case, these repeatedly exert impulses essentially in the direction of gravity and beat the hemp grains from the crop.

A return spring 37 allows evasion of the crop guide plate 37 in the direction of impact of the active organs 22 , guides the crop guide plate 37 but then back to their starting position. The shaking out of the crop for grain extraction is thus optimized. The articulated arrangement of the crop guide plate 36 is an advantageous embodiment, but it is not mandatory. The crop guide plate 36 can also in a rigid version, the crop of the threshing drum 8th respectively. Furthermore, the evasive movement of the crop guide plate 36 also be done by means of a forced control.

In contrast to conventional cereal threshing, in the present case a concave or similar guide elements has been dispensed with, which move the crop on its trajectory below the threshing drum 8th to lead. The crop arrives from the feeder 30 , the threshing drum 8th tangent, directly to the subsequent, not shown here separating and cleaning device.

Complete the previous description of the harvester 101 and the assemblies detailed in the following:
All above the Erntegutstromes arranged devices, in particular the upper conveyor belt 4 of the feederhouse 102 , the upper rollers 6 . 9 and 21 of the muzzle organ 103 and the counter-drums 10 the threshing device 104 are height-adjustable mounted to different strengths of hemp swath 101 that originate from a different plant density within a stock, to be adaptable.

Contrary to the description underlying, preferred threshing, which already pre-mowed hemp swath 101 the threshing device 104 after the field roast feeds, can also be a cutting unit on a harvester 101 be provided so that a direct threshing can be done without previous field roast.

To ensure a trouble-free crop flow through the harvester 100 or to ensure their organs, the second organ following a first organ accelerates the crop a little more. Consequently, it is advantageous if the Umlaufge speeds in Erntegutflussrichtung increase from organ to organ slightly. Especially in the field of numerous drums 8th . 10 . 12 and rolling 5 . 6 . 7 . 9 20 . 21 and 29 , but is a common drive for grouped drums 8th . 10 . 12 and rolling 5 . 6 . 7 . 9 20 . 21 and 29 desirable. In order nevertheless to ensure a continuously increasing rotational speed, the respective following drum 8th . 10 . 12 or roller 5 . 6 . 7 . 9 20 . 21 and 29 a correspondingly larger diameter than the previous one.

Ultimately serve the above-described organs of the harvester 100 among other things, the propulsion of the crop and are therefore driven in principle in Erntegutflussrichtung and / or rotatable, which also illustrate the different arrows in the figures. However, this includes a reversion operation of individual or all organs - for example, to eliminate blockages of the machine 100 - not from.

Since hemp grains sit relatively loosely in the inflorescences, there is the possibility that some of the grains already in the area of Erntegutaufnahme, especially in the range of the inclined conveyor 102 fall out of the crop. In order to avoid crop losses as far as possible, a device for catching hemp seeds can therefore already be provided in this area.

Part of the invention, in addition to the device for threshing in particular hemp and a method for hemp threshing. In this method, plants previously placed in the swath after the field roast or directly cut plants of a threshing device 104 fed. The threshing device 104 has at least one threshing member, for example a prescribed threshing drum 8th on which the hemp plants are fed. The threshing drum 8th regularly exerts an impulse on the crop and shakes or beats so comparatively loose sitting in the inflorescences Hemp seeds off.

An improved expression result can be achieved by assigning to the threshing organ a counter-organ which exerts a pulse following the pulse on the crop passed between the two organs. As a counter-organ can the above-mentioned counter-drum 10 serve. Depending on the requirement, the crop is also guided over a range of threshing organs and any counter organs.

in the Following the threshing, so the knocking or shaking the Cannabis seeds, the hemp is over a separating and cleaning device out. Here is the crop loosened up, so even though previously gestroschene, but still Hemp grains not fallen through the plant material via a conveyor belt or directly onto a Sieftrecke arrive.

The Separate screens and any cleaning fan hemp seeds and smaller plant parts. The cleaning is essentially analog for cleaning threshed grain. Subsequently, will the expression of a reservoir fed.

This Threshing process leaves in towed, self-propelled or stationary harvesters deploy.
