MACHINE FOR COLLECTING AND CLEANING COFFEE BEANS IN

COCONUT.

Field of the Invention.

More particularly, the present invention relates to technical and functional improvements specially developed and introduced in the subsets that configure a machine to collect and clean coconut coffee beans.

It is known that there are different ways to harvest beans in coffee trees. This harvest can be manual, semi-automatic or automatic. Logically, all of these forms have a certain efficiency in the harvesting work, varying only in terms of speed. Regardless of the means used for harvesting, it is very common to spread a considerable amount of grains on the ground, which are usually heaped on the streets between the coffee trees and, in this condition, are collected and are also processed for proper cleaning.

The present machine for collecting coffee beans in coconut is of the type classified as a trawler to perform three different operations: a) collecting the beans in coconut previously rowed;

b) perform a complete cleaning process separating the grains (seeds) from the other disposable parts; and

c) storage in a bucket provided in the machine itself, where said bucket has means so that it can be tilted for quick unloading at the desired moment.

State of the art.

There is no doubt that the machines and implements currently known have the necessary resources to collect and clean coffee beans in coconut, however, some of them are limited and others have a really high manufacturing cost, even so, they do not provide equipment ideal for medium and small producers. On the other hand, traditional machines present constructive details that wear out very easily, particularly with regard to the system that collects grains with impurities, since the usual implements considered more efficient are motorized and others have a suction or collector system. , they also use collecting shovels with low production efficiency.

Therefore, the biggest problems encountered with conventional equipment are, without a doubt, the constructive complexity, generating oversized machines that require special care in their operation, some of them require the presence of an operator constantly, this and other factors contribute to define an equipment cost

10/28 high, not only with regard to the manufacturing process, but also with regard to the operation of the set.

Objectives of the Invention.

In view of the above circumstances and in order to overcome them, this MACHINE FOR was created. small _AND LiMgftR COFFEE GRAINS IN COCONUT, developed with a monoblock chassis that, at the bottom includes a transverse axle for a pair of wheelsets, as well as at its front end includes universal hitch lance to be towed by a usual tractor and, still At this very end is the first drive system for all machine assemblies, thus defining equipment of the type classified as drag to carry out three different operations: a) collection of previously rowed grains; b) carry out a complete cleaning process separating the qrao (seeds) from the other disposable parts; and c) storage in a bucket provided on the machine itself, where said bucket has means so that it can be tilted for quick unloading at the desired time.

To carry out such operations, the machine includes a first cardan shaft to be coupled to the tractor's power take-off and, thus, different subassemblies are simultaneously activated, starting with a collecting belt for the material to be processed. This set was designed to provide different advantages, that is, it is a mat that works with a certain inclination so that only its front end touches the floor, where side skids provide means for this end to copy all the

11/28 irregularities of the soil, following its profile during the movement of the machine on the material to be harvested, which, in turn, consists of coffee beans (coconut) and others. This recoil occurs at a considerable speed, since the conveyor has several rubberized transverse vanes, which work like true shovels, continuously picking up the material and throwing it over another two overlapping sets defined as stirring and sieve sets. In this route, a first stage of cleaning by suction begins through side ducts and a fan. The stirring assembly agitates the material in order to loosen the remaining connections between coffee beans and their branches. The beans pass through two vibrating sieves and are then collected by other sets and taken to an upper bucket and, in this route, another suction set performs the last cleaning step. Completely clean grains are stored in the referred bucket, which, in turn, has resources to be tilted at the time of unloading.

As can be seen, it is a compact machine, without motorization, since it uses the tractor's power take-off, consequently, its operation is really advantageous, since all the sub-assemblies are interconnected for automatic operation, dispensing the attention of a specific operator, that is, only the tractor driver comfortably controls all operations of the machine in question.

On the other hand, the constructive form and the arrangement of the sub-assemblies on the monoblock chassis give the concretization of a compact and costly harvester

12/28 substantially low, serving small and medium producers.

Another important aspect in the machine in question is simplicity of design, both in the structural part, as well as in the assembly of the sub-assemblies, which contributes to increase the useful life of the assembly and also greatly simplifies the maintenance, corrective or preventive operations.

According to these illustrations and in their details, the present invention, MACHINE FOR COLLECTING AND CLEANING COFFEE GRAINS, comprises, as illustrated in figures 1 and 2, a monoblock structure (1), made with a plurality of tubes and welded plates, cooperative for configuration of

16/28 five distinct parts (2-3-4-5-6), where the first (2) is a lower frame defined by side members (7) and sleepers (8-9), one of them for the transverse axis arrangement ( 10) and respective shooting (11); the second part (3) is an ordinarily parallelepiped structural complement positioned practically on the middle part of the frame (2), where said second part is formed by tubular uprights (12) and upper tubular crosspieces (13-14); the third part (4), in addition to being a rear structural complement to the structure (1), is formed by plates that combine to configure an air box with two suction sources (15-16) and respective outlet ducts ( 17-18) through which straw and other impurities leave the harvested grains; the fourth part (5) is formed on the anterior side of the second part (3) and on the first third of the side members (7), where a wedge-shaped structural complement is formed, defined by two longitudinally inclined tubular pieces (19 ) above the side members (7) and with which they are joined at the front together with side plate squares (20) and also with the last part (6) which is a fully plate mounting box.

As figures 3 to 6 illustrate, the monoblock structure (1) and its construction details provide the means for assembling all the mobile and fixed subsets that form the machine in question, which, as already mentioned, is of the type to be towed by tractor during its operation and, for that, the front part of the structure (1) receives a first

17/28 set defined as a hitch boom (21) with all the necessary resources to be hitched on a usual tractor, as well as a foot rest (22) of the type with height adjustment by means of a crank.

Above the hitch boom (21) and inside the mounting box (6) is the transmission and power take-off assembly (23), which, on the one hand, has the means to be directly coupled to a tractor's power take-off usual and, on the opposite side, it presents derivations to drive all the sub-assemblies of the machine, starting with a collecting belt (24) and respective lifting set (25) inclined between the side members (7) of the structure (1) and in the section comprised by the complement of wedge structure (6), where the anterior end of the said collecting mat (24) is practically oriented to slide on the ground and against the grain and impurities, launching them into said mat, whose other higher end, in addition to being equipped with two lateral cleaning suction ducts (26), also ends inside an inverted discharge mouth (27) which, in turn, is positioned inside the structure (3) and about a set i defined as a stirrer (28), branch deinterleaver and grain release from said branches, as well as moving the processed material backwards by sliding it over a set of vibrating screens, a shorter top (29) and a longer bottom ( 30), where the first ends under the suction box (4), thus defining another

18/28 cleaning phase, as this removes all impurities larger than grains (branches, leaves and others), allowing the passage of grains and minor impurities to the second sieve, which in turn also passes under the box suction pipe (4) and ends at a clean grain transverse transport chute (31) having an interconnected end to transfer the grains to a clean grain elevator (32), the upper end of which ends at a discharge spout (33 ) oriented towards the inside of a tipping bucket (34), where the grains are stored and, when necessary, said bucket is tipped to unload the clean grains.

As shown in figures 7 and 8, the mounting box (6) has an ordinarily rectangular front shape, as well as defined by two plates, an anterior (35) and a posterior (36), joined in the contour by other closing plates some of which with ventilation grilles (37a) and also on the upper plate there is a support (38) with a longitudinal tubular part (39) for the passage of hydraulic hoses, and also on the front plate (35) and rear plate (36) there are meshed covers (37b) and other different mounting openings and access to the transmission set (23).

The transmission and power take-off assembly (23) is illustrated in detail in figures 9 and 10, where it appears that it comprises an initial set of four pulleys, one larger (40) and its solidary smaller reduction pulley ( 41), the first

19/28 is

it is interconnected by middle of belts (42) with pulley (43), while the pulley slave (41) interconnected through of belts (44) with an pulley larger (45), all they with yours

bearings in the mounting box (6), except the first pulley (40) whose axis is bearing in two plates (46) which, through their slots (47), are fixed in the mounting box (6), where said plates in set with threaded spindles (48) also configure belt tensioners, also providing other tensioners (49) for the belt (44), and the axis of the first pulley (40) is also coupled at one end of a cardan shaft (50), while its other end has universal coupling coupling to the PTO of a usual tractor, whose power is transmitted to the first pair of pulleys (40-41) which, through the belts (42-44) prints different rotations on the other pair of pulleys (43-45), also illustrated in figures 11 to 14, where the axis of one of them (43) is extended (51) through several bearings and universal joints until reaching the air box (4) and go through the suction sources (15-16), where each one receives its correspondence between ventilation turbine (52) and (53), and a similar construction also occurs with the other pulley (45), however, in this case its axis is coupled to a cardan shaft (54), the other end of which is coupled in a 90 ° transmission box (55), the output shaft of which is equipped with transmission gear (56) and the respective chain

20/28 (57) with tensioner (58) for connection connection of the collecting belt (24).

The collector conveyor (24) is illustrated in detail in figures 15 to 23, showing that it is in the form of an ordinarily parallelepiped box, defined by side plates (59) which, in addition to having rounded ends (60), one of them, the upper one, is structured with a partial rounded closure (61) and internal busbars (62), providing for two other incomplete closures, a plate top (63) and a lower one in the form of sieve (64), in which the first leaves an upper open part of approximately 1/3 (65) of the length of the set, which also happens in the lower part, however, this opening (66) is located in the upper end and faces into the interior of that inverted discharge mouth (27), where this part also serves to maneuver the upper end of said belt (24) through its axis (67), whose ends also have gears (68), one of them (fig. 13) coupled to the chain (5 7) of the transmission set (23), since said axis (67) is for traction for the conveyor itself, configured in conjunction with another transversal axis (69) also bearing on the lower ends of the side plates (59), this axis being (69) and the previous one (67) have gears (70) for chains (71), preferably three, interconnected by several flexible reeds (72), each with a rectangular shape and

21/28 disposed transversely on the chains (71), where they are fixed between plates (73a) and angles (73b), forming the collecting belt itself that moves over rulers (74) close to the upper plate walls (63 ) and lower in the form of a sieve (64), the latter allows part of the impurities to be eliminated, mainly earth and, still under said sieve there is a transversal hood (75) whose ends are coupled to the suction ducts (26), so that dust in this region can be collected and disposed of at the rear of the machine.

As shown in figures 17, 18 and 19, the lower or front end of the collecting belt (24) is equipped with a pair of skis (76) so that, during the operation of the machine, it can slide and monitor any irregularities on the ground, with that, this end is moved against the windrow of coffee beans in coconut and, still, as illustrated in figures 15 and 16, the lift assembly (25) also means to keep the end of the collecting mat stable therefore, it is maintained with a suspension constituted by a lower end by a pair of helical springs (77), whose lower ends are coupled in supports (78) on the sides

59) of said collecting mat (24), while the upper ends are coupled in threaded tensioning rods (79) also anchored in cushions (80)

22/28 arranged on supports (81) existing in the structure (D.

Still with respect to figures 15 and 16, part of the lift assembly is a mechanism for lifting the corresponding end of the collecting belt when it is not in use. This device is formed by a transverse axis (82) bearing on the structure (1), where it has a short radial lever (83) driven by hydraulic cylinder (84), cooperating to print a semi-rotation on said axis (82 ) and angularly move two radial arms (85) welded along its length, these arms on whose hook ends are coupled chains (86), which have the

lower extremities coupled in parts corresponding gives pickup mat (24), allowing o 4- -> vJ O * L »O be lowered and raised in desired moment. as already was said before see figure 24, the material moved at the inland gives running machine collector (24) is dispensed by the mouth (26) over the set stirrer (28) what, in its turn, deinterlace

the branches and causes the release of the grains of said branches or similar parts, so that the processing can continue and, for that, the said stirring set (28) is constituted, as also illustrated in figures 25 to 28, by transverse axes (87), preferably three, all bearing on the frame members (1), where they are all synchronized to rotate at the same time and, for

23/28 both, have their ends equipped with gears (88) for chains (89) that constitute continuity of the motor transmission system (23) starting from the gear (68) of driving the collecting belt (24), being that, further, rotating blades (90) are distributed along the axes (87), each formed by a piece of star-shaped plate with four radial points (91) which, in the central part, includes a fixing sleeve (92) on the corresponding axis using a key or any other mechanical means, while on the opposite side the ends of said sheet piece are perpendicular to each other, each end receiving a proper blade (93), as seen in plan, the stars or blades of a θιχο fic θπιγθ ss blades of the Hdjscente axis, with the blades on the first axis passing through a comb-like edge (94) configured in the corresponding mouth wall (26), thus preventing the processed material from returning to said mouth (26), that is, at the passing through the latter is grasped by the blades of the first axis and then launches towards the subsequent axes, promoting controlled impacts on the product, enough so that it is not tangled in the machine and also causes the release of the grains in relation to the branches consequently, at this stage, part of the material is driven through the sieves (29-30).

As already mentioned, (see fig. 29) the machine includes a set of vibrating screens, a shorter top (29) and a longer bottom

24/28 (30), in which the first ends under the suction box (4), thus defining another cleaning phase, since in this all impurities larger than the grains (branches, leaves and others) are removed, allowing the passage of grains and minor impurities to the second sieve, which, in turn, also passes under the suction boxes (4) and ends on the transverse transport chute of clean grains (31).

As figures 30 to 33 also illustrate, the vibrating screens (29-30) are in the form of overlapping gutters with their respective side (95) and rear (96) walls, through which they are aligned over each other with a certain distance and fixed suspended by four flexible uprights (97), which have their lower ends fixed in the structure (1), or more precisely in the side members (7) and, also, triangular lateral supports (98) also join the two sieves (29—30), these supports being support points for the ends of an axis (99), where a vibrating device (100) is constituted, constituted by a triangular piece (101) which, on the one hand is coupled to said axis (99) while its apex culminates in a coupling part (102) that forms an integral part of a cam (103) mounted on another transverse axis (104), also bearing in the structure (1), where one of its ends receives gear (105 which, through color chain (106) is coupled to another gear (107) of the motor transmission assembly (23).

25/28

Therefore, the set described above allows the final cleaning to be carried out, that is, impurities that do not pass through the upper sieve (29) are aspirated in (4), consequently, what passes through the second sieve are grains and other small impurities, where the lighter ones are also sucked at the end, while smaller particles fall to the ground after passing through the second sieve (30) and, at this point, only the clean coconut coffee beans are led to the transport chute (31).

As shown in figures 34 and 35, the transport rail (31) is positioned at the end of the structure (1) and below the air box (4), where these two parts combine to form a rectangular outlet (108), exactly over the extended section of the lower sieve (30), and this outlet also has its upper part equipped with a tilting lid (109) for inspection and cleaning, with the so-called transport rail (31) below this whole set. , seen in detail in figures 36, 37 and 38, showing that it internally has a conveyor thread (110) and its axis (111) which, in turn, has its ends bearing in the structure (1), where one of them is extended enough to also form the drive shaft of the clean grain elevator (32) and, for that, one of its ends receives a gear (112) which, by means of chain (113) constitutes a continuation of the motor transmission set (23) that passed through the set not stirring (28).

26/28

Therefore, the set above, that is, the transport chute (31) has the function of receiving only the clean grains, since the final impurities were either sucked up by the set (4) or eliminated by the outlet (108), leaving for behind the clean grains that pass through the sieve (30) and fall into the transport chute (31) to be sent to the elevator of clean grain mugs (32).

rounded (31) to

Figures 39 to 41 show the construction details of the clean grain mug elevator (32), which consists of a slightly inclined tower (114), with plates, including inspection lids (115) and bottom end (116) aligned axially with the gutter to receive the clean grains of the latter, as well as in the center of that rounding (116) passes that axis (111) which, together with another superior one (117), receives gears (118-119) for a chain (120) along which mugs (121) are distributed, oriented to pass overturned by the rounding (116) where they are loaded when unloading and, when they reach the upper end of the tower (114) they overturn again to be unloaded at the spout (33) where the grains clean are driven to the bucket (34).

The spout (33) has a rectangular end or spout (122) that matches the width of the tilting bucket (34), this mouth is fixed directly on the corresponding edges of the tilting bucket (34), so that both can move,

27/28 and said spout (33) also has the opposite side or inlet mouth defined by a collar (123) that adjusts by simple seating at the upper end of the tower (114) of the mug elevator (32) .

The tipping bucket (34) is illustrated in detail in figures 42 and 43, where it can be seen that it initially comprises a pair of gantry beams, one on each side (124), each formed by two tubes inclined, whose upper ends are joined and constitute a point of bearing for an axis (125), while the lower ends of the beams are fixed on the uprights (12) of the complementary structure (3) of the structure (1), so that said axis (125) is positioned substantially high and out of the right side of the machine, maintaining parallelism, as it constitutes a point of articulation and is integrated with the corresponding edge of the bucket (34), which, in turn, is defined with a quadrangular bottom and smooth walls or in the form of sieves, where the anterior and posterior walls are vertical, while the lateral walls are substantially inclined, forming a mouth substantially larger than the base, this mouth on which it stands that spout (33) of the elevator (32) is attached, while on the opposite side it is articulation with the axis (125), being between these two points, or more precisely in the first third of the width of the bucket mouth (34), a crosspiece whose points constitutes axis (126) for the upper ends of

28/28 hydraulic cylinders (127), one on each side, whose lower ends are housed on supports (128) on the complementary structure (3), so that said cylinders (127) can extend as illustrated in the figures of 44 to 46, through which the maximum extent of said hydraulic cylinders (127) is verified at the moment when the bucket is unloaded. Logically, this unloading can occur under various conditions, such as, for example, inside another bucket or body of a clean grain transport vehicle, however, regardless of such aspects, the unloading of the bucket (34) is carried out quickly. and efficient.
