Corn husking and grain collecting device
for harvest deshelling machines

The innovation relates to automatic harvesting and husking machines for maize. In particular, it relates to machines of the type with a cab provided with a self-propelled body, means for collecting the ears of corn and for separating the ears of corn from the stalks,
De-husking means for removing the grains from the ears of corn and from the leaves and bracts, means for
Cleaning the grains and a container to hold the
Grains. After these operations are completed, the grains
conveyed out of the container and stored before being bagged or placed in silos.

One of the main disadvantages of machines of this type is the high percentage of lost grain. Such a loss

24- (CASO II) -Tp-r (6)

occurs mainly when separating the leaves and main leaves, with which many peeled grains are mixed remain, resulting in incomplete separation of the grains from the leaves.

In addition, known machines of the type mentioned above can only either be used for the actual removal of the sleeves Corn on the cob or just for making corn on the cob feed (corn mix) depending on the type of husking device used use.

The innovation is based on the task of and grain collecting device for a crop dehulling machine indicate which is essential to the separation of the leaves and main leaves during the doorway Reduction or elimination of the loss of grain a and an extraction of the grains possible without damage. ! Next to it should the innovation offer such a device that makes it possible to use the same machine without prior special adaptation to be used either for harvesting and peeling corn or for harvesting and producing corn on the cob (corn mix), so as to increase the versatility of the machine with a corresponding reduction in costs and labor.

The object of the innovation, with which this object is achieved, is a corn cob de-husking and koraaammelvorrichtung for a maize crop husk with one after the other arranged at the exit of a rotary harvester first and second rotary cylinders with the same rotary direction for conveying the Naiskolbenblätter and -deokblältter to one Shaking device and a perforated impactor arranged under the cylinders to allow maize kernels to pass through

surface, with the indicator that the impact surface from a first, firmly attached under the first cylinder form impact element and a second oscillatingly arranged under the second cylinder and by the shaking device form parallel member that can be set in oscillating motion consists.

Preferably, the second cylinder is allowed to rotate at substantially twice the speed of the first cylinder rotate.

The wide baffle element is preferably designed in such a way that the threshed products from it against a top arranged concave hood, causing a sharp deflection and falling of the moving material causes the shaker, whereby the extraction of the Corn kernels is improved.

The innovation is based on the non-restrictive exemplary embodiment illustrated in the drawing explained in more detail; show in it:

Flg. 1 is a schematic side view, partly in

Cut, an automatic harvest wrapping machine for maize with a skinning and crown collecting device according to the innovation;

According to Fig. 1, the automatic harvesting En thill search machine for corn on a body 1, which eit an internal combustion engine 2 is provided for the forward movement and operation of the machine. At the front of the machine is a driver's cab 3t under which harvesting devices 4 for cutting the ears of corn from the field and for separating the ears of corn from the stalks. Inside the body are means for peeling the ears of corn, means for removing the leaves and main leaves, and simultaneously Extraction of the grains, means for cleaning the grains and an upper container 5, in which the cleaned Grain is introduced by means of an upward conveyor 6. The grain is removed from the container 5 by means of a screw conveyor 7 ', preferably of the adjustable type.

As FIGS. 2 and 3 show, the means for peeling the corn on the cob and collecting the kernels comprises successively a plurality of devices, some of which rotate and some of which are arranged in a fixed or oscillating manner which cause a sequence of operations that cause the separation of the corn kernels from the ears and The aim is to separate the grains from the leaves and main leaves.

The harvesting devices 4 comprise continuous conveyors, which the conveyed material in a threshing or cutting, Promote device 8, which consists of a cylindrical drum rotating about a lateral horizontal axis the surface of which extends along the surface lines of rods 8a and which cooperates with a stationary counter thresher 9, which consists of a cylinder sector and with radially inward, protruding teeth or rods and longitudinal

protrusions is provided. The thresher 8 is similar to which is used in mower-threshing machines, and enables both the husking of the harvested corn on the cob as well as the preservation of lumps of corn on the cob (corn mix), a product that can be obtained with the well-known husking devices, which have impact cylinders without making any significant changes to those used in the machine Couldn't get facilities.

Behind the thresher 8, two transverse cylinders 10, 11 are mounted one after the other, which rotate in the same direction as the thresher 8, but at different speeds. The first cylinder 10 is provided with many rows of protrusions and rotates at a not high speed, while the second cylinder 11 is provided with at least two rows of diametrically opposed protrusions and rotates at twice the speed of the cylinder 10. Under the first cylinder 10 is arranged a first stationary, quergeripptes, perforated or Siebprallelement 12, is connected to the k at its front end "\ with the end of the counter-thresher. 9 under the second cylinder 11 is a second oscillating, ribbed, perforated or Siebprallelement 13, the front end of which is connected to the rear end of the fixed impact element 12 by means of Erehzapfangliedern 15 (shown in phantom).

The two impact elements 12, 13 under the cylinders 10, 11 are concave and provided with holes or slots, through which the under the action of the rotating cylinder

Under 10, 11 centrifuged grain fills while the leaves and main blades over the elements 12, 13 to the exit end the machine can be moved further,

In particular, the second baffle element 13 is arranged and set up in such a way that it moves the material towards the interior
a dome 27 directs that is at the top of the machine
is trained. The material is thrown against the dome 27 and thereby sharply deflected to fall onto the shaker 17 with virtually no loss of grain. The second impact element 13 is
connected to the shaking device 17 and is through
this is set in oscillating motion, whereby a more effective separation of the grains from the leaves and main leaves is ensured when the cut pistons pass under the second cylinder 11.

The shaker 17 comprises a frame 18 of rectangular shape which carries a plurality of transverse strips 19 with L-cross section and a plurality of metal screen plates 20 which extend longitudinally. The frame 18 is supported at its front end by a pair of oscillating double levers 21, which are pivotally supported by two fixed transverse pins 22 and are arranged so that they can be oscillated by rods 23. The rods 23 are oscillated in a substantially vertical direction by a crank mechanism 2k. At its rear end, the shaking device 17 is through
Trunnion members 26 are supported which are pivotable with a
fixed structural part 25 are connected relative to which the device swings in a substantially horizontal direction. Therefore the material is on the front

End of the Schilttelrahmens 18 a shaking movement in almost subjected to the vertical direction in order to collect all the grains that may be present, however, at the rear end of the frame subjected to an almost horizontal movement so that the thickness of the material on the rocker frame 18 from the front end decreases towards the rear of the device. Veiter In the rear part of the shaking device 17, the lighter ones Prevented materials from passing the underlying sieve plates 20 by using an upwardly directed Air flow is worked, which penetrates the shaking device from below. The airflow blows the lighter waste materials directly, thereby eliminating the risk of overloading the sieve plates 20 while the heavier grains can pass through the plates 20 into a bottom container.

The combination of the two movements of the shaker 17 enables the formation of a material layer, which advances very slowly over the device 17 and is shaken vigorously as it enters the device, then but advances faster towards the rear of the device 17, the amplitude of the shaking towards the rear sinks. Such movement enables substantially complete recovery of the grains and reduces them Losses.
