Description

MACHINE. FOR. COLLECT AND CLEAN COFFEE BEANS IN COCONUT.

Field of the Invention.

More particularly, the present invention relates to specially developed technical and functional enhancements introduced into the subsets that configure a machine for collecting and cleaning coffee beans in coconut.

It is well known that there are different ways to harvest the beans in coffee trees. This harvest can be manual, semi-automatic or automatic. Of course all these forms have a certain efficiency in the harvesting work, varying only as regards the speed. Irrespective of the means used for harvesting, it is very common for a considerable amount of grain to be scattered on the ground, which is usually piled on the street between the coffee trees and, in this condition, is collected and processed for proper cleaning.

The present cocoa coffee bean harvester is classified as a trailing machine to carry out three distinct operations: a) collection of previously raked coconut beans;

b) perform a complete cleaning process separating the grains (seeds) from 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 rapid unloading at the desired time.

State of the art. There are currently several equipment and machines for the above purpose, some really very simple and some more complex, however, in one way or another have many features for collecting and cleaning the grain, as taught, for example, some documents already known:

GRAIN COLLECTOR AND SHAKER TURBO, COFFEE COFFEE AND CAPIME SEEDS.

There is no doubt that the currently known machines and implements have the resources needed to collect and clean coconut coffee beans, however, some of them are limited and others have a really high cost of manufacture, yet they do not provide ideal equipment. for medium and small producers. On the other hand, traditional machines have constructive details that wear out very easily, particularly with regard to the grain picker system with the impurities, as the usual implements considered more efficient are motorized and others have suction picker system or They also use pickers with low production efficiency.

Therefore, the biggest problems encountered with conventional equipment are undoubtedly 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 compete to define an equipment. costly not only for the manufacturing process but also for the operation of the assembly.

Objectives of the Invention.

In view of the above circumstances and with the aim of overcoming them, the present COCONUT COFFEE COLLECTING AND CLEANING MACHINE has been created, developed with a one-piece chassis which, at the bottom, includes a transverse axis for a running pair, as well as at its front end it includes a universal drawbar to be towed by a standard tractor, and at this same end is the first drive system of all machine assemblies, thus defining a drag-type type equipment to perform three distinct operations: a) collection of previously rowed grains; b) perform a complete cleaning process separating the grain (seeds) from other disposable parts; and c) storing in a bucket provided on the machine itself, where said bucket has means so that it can be tilted for rapid unloading at the desired time.

To perform such operations, the machine includes a first cardan shaft to be coupled to the tractor PTO, and thus different subassemblies are driven simultaneously, starting with a conveyor belt of the material to be processed. This set is designed to provide different advantages, ie it is a treadmill that works with a certain inclination so that only its front end touches the floor, where side skates give means for this end to copy all the irregularities of the ground, following the 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 retraction occurs at a considerable speed, as the conveyor has several rubberized transverse vanes, which act as true blades, continuously harvesting the material and throwing it over another two overlapping sets defined as stirring set and sieve set. This route begins a first step of cleaning by suction through side ducts and a fan. The stirring assembly shakes the material to loosen the remaining bonds between coffee beans and their branches. The grains pass through two vibrating screens and are then collected by other sets and driven to an upper hopper, and in this course another suction set performs the last cleaning step. Completely cleaned grains are packed in the said bucket which, in turn, has the resources to be tilted at the time of unloading.

As it turns out, it is a compact machine without motorization, since it uses the tractor PTO, therefore, its operation is really advantageous, since all subsets are interconnected for automatic operation without the attention of a specific operator, ie only the tractor driver comfortably controls all operations of the machine in question.

On the other hand, the constructive shape and arrangement of the subassemblies on the one-piece chassis make it possible to achieve a compact and substantially low cost harvester, catering to small and medium producers.

Another important aspect in the machine in question is simplicity of design, both structural and subassembly, which contributes to increase the life of the assembly and also greatly simplifies maintenance, corrective or preventive.

In accordance with these illustrations and their details, the present invention, COCONUT COFFEE GRAIN COLLECTING AND CLEANING MACHINE, comprises, as illustrated in Figures 1 and 2, a one-piece structure (1) made of a plurality of tubes and welded plates, cooperative for configuration of five distinct parts (2-3-4-5-6), where the first (2) is a lower frame defined by stringers (7) and sleepers (8-9), one of them for arrangement with transverse axis (10) and respective running-in (11); the second part (3) is an ordinarily parallelepiped structural complement positioned practically over the middle part of the frame (2), wherein said second part is formed by tubular mounts (12) and upper tubular sleepers (13-14); the third part (4), besides being a rear structural complement of the structure (1), is formed by plates which combine to form an air box with two suction sources (15-16) and respective outlet ducts ( 17-18) through which straw and other impurities come out of the harvested grain; the fourth part (5) is formed on the front side of the second part (3) and over the first third of the stringers (7), where a wedge-shaped structural complement is formed by two longitudinally inclined tubular pieces (19). ) above the stringers (7) and with which they are joined in the front part together with side plate brackets (20) and also with the last part (6) which is an all-metal mounting box.

As shown in Figures 3 to 6, the one-piece structure (1) and its constructive details provide means for mounting all movable and fixed subsets forming the machine in question which, as has been said, is of the type to be towed by tractor during its operation, the front part of the structure (1) receives a first set defined as a drawbar (21) with all the necessary resources to be attached to a usual tractor, as well as includes a rest foot ( 22) of type with crank height adjustment.

Above the drawbar (21) and inside the mounting box (6) is mounted the transmission and power take-off assembly (23) which, on the one hand, has means to be coupled directly to the power take-off of a tractor. On the opposite side, it has derivations for driving all the subassemblies of the machine, starting with a pick-up belt (24) and respective lift assembly (25) inclined between the spars (7) of the structure (1) and in the section comprised by the wedge structure complement (6), where the front end of said pickup mat (24) is oriented practically to slide over the ground and against the grain and impurities, throwing them into said mat, whose other higher end, besides being equipped with two side suction cleaning ducts (26), also ends inside an inverted discharge mouth (27) which, in turn, is positioned inside the structure (3) and about and a set defined as stirrer (28), de-interleaving and loosening the grain of said branches, as well as moving back the processed material by sliding it over a set of vibrating screens, a shorter upper (29) and a lower longer (30), where the first one ends under the suction box (4), thus defining another cleaning phase, since in it all impurities larger than the grains (branches, leaves and others) are removed, allowing the passage the smaller grains and impurities to the second sieve, which in turn also passes under the suction box (4) and ends in a clean grain transverse transport chute

(31) having an interconnected end for transferring the beans to a clean grain mug elevator

(32), the upper end of which ends in a discharge spout (33) oriented into a tipping hopper (34), where the beans are stowed and, at the required time, said hopper is tipped for unloading the cleaned beans.

As shown in figures 7 and 8, the mounting box (6) has an ordinarily rectangular frontal shape, as well as defined by two plates, one anterior (35) and one 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 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 assembly (23).

The transmission and power take-off assembly 23 is illustrated in detail in figures 9 and 10, where it is shown that it comprises an initial set of four pulleys, one larger (40) and their integral lower reduction pulley ( 41), the first is interconnected by belts (42) with another pulley (43), while the slave pulley (41) is interconnected by belts (44) with another larger pulley (45), all of them with their axes biased in the mounting box (6), except the first pulley (40) whose axle is biased in two plates (46) which, through their slots (47), are fixed in the mounting box (6), where said The plates together with threaded spindles (48) also form belt tensioners, and other tensioners (49) are also provided for the belt (44), and the shaft of the first pulley (40) is also coupled to one end. of a cardan shaft (50), while its other end has universal coupling coupling to the power take-off 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. 11-14, where the axis of one of them (43) is shown, it is extended (51) through several bearings and universal joints until it reaches the air box (4) and crosses the suction sources (15-16). ), where each of them receives its corresponding ventilation turbine (52) and (53), and, similarly, a similar construction happens with the other pulley (45), but in this case its axis is coupled to an axis cardan (54), whose other end is coupled to a 90 ° gearbox (55), whose output shaft is equipped with gear (56) and its chain (57) with turnbuckle (58) for drive connection of the pickup belt (24).

The pick-up mat 24 is illustrated in detail in figures 15 to 23, where it is shown to be 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), and two other incomplete closures are provided, one plate top (63) and one inferior in the form of sieve (64), wherein the former leaves an upper open portion approximately 1/3 (65) of the length of the assembly, which also happens at the lower portion, but this opening (66) is located at the upper end and faces into that inverted discharge mouth (27), where such part also serves to bias the upper end of said belt (24) through its axis (67), whose ends also have gears (68), one of them (fig. 13) coupled to chain (57) of the transmission assembly (23), as said shaft (67) is of traction for the belt itself, configured together with another transverse axis (69) equally biased at the lower ends of the side plates (59), where this shaft (69) and the former (67) have chain gears (70), preferably three, interconnected by several flexible vanes (72), each rectangular in shape and arranged transversely over the chains (71), where they are fixed between plates (73a) and angles (73b), forming the pick-up mat itself which moves over rulers (74) flush with the upper (63) and lower sieve plate walls (64), the latter It allows part of the impurities to be eliminated, mainly soil and, furthermore, under this sieve there is a transverse hood (75) whose ends are coupled to the suction ducts (26), so that dust in this region can be collected and dispensed. at the rear of the machine.

As shown in figures 17, 18 and 19, the lower or front end of the pick-up belt 24 is equipped with a pair of skis 76 so that during operation of the machine such an end can slide and follow any irregularities on the machine. the ground thereby moves the end against the coffee bean coil and further, as shown in figures 15 and 16, the lift assembly 25 also provides means for maintaining the lower end of the therefore, this end is maintained with a suspension consisting of a pair of coil springs (77), whose lower ends are coupled to supports (78) on the sides (59) of said collector (24), while the ends upper parts are coupled to threaded tensioning rods (79) also anchored in pads (80) arranged in brackets (81) in the frame (1) ·

Referring also to FIGS. 15 and 16, a mechanism for raising the corresponding end of the pick-up mat when not in use is part of the lift assembly. This device is formed by a transverse axis (82) biased over the structure (1) / where it has a short radial lever (83) driven by a hydraulic cylinder (84), cooperating to print a semi-rotation on said axis (82). ) and angularly move two welded radial arms (85) along their length, which arms on which hooked ends are attached to chains (86), which have the lower ends coupled to the corresponding parts of the pickup belt (24), allowing it is lowered and raised at the desired time.

As has been said before, see figure 24, the material moved within the pickup conveyor (24) is dispensed by the mouth (26) onto the stirring assembly (28) which in turn deinterlaces the branches and causes the grains to loosen. said branches or similar parts, so that processing can continue and, to this end, said stirring assembly (28) is constituted, as also illustrated by figures 25 to 28, by transverse axes (87), preferably three, all in the frame spars (1), where they are all synchronized to rotate at the same time and, to this end, have their ends equipped with chain gears (88) which constitute continuity of the motor transmission system (23) from the drive belt drive gear (68) (24), further along the axes (87) rotating blades (90) are each formed by a four-piece star-shaped sheet metal radial tips (91) which at the center includes a clamping sleeve (92) on the corresponding shaft using a key or some other mechanical means, while on the opposite side the tips of said sheet metal are perpendicular to each other tip receiving a shovel itself (93), as seen in plan view, the stars or blades of an axis are between the blades of the adjacent axis, and on the first axis their blades pass an edge in the manner of comb (94) configured in the corresponding mouth wall (26), thus preventing the processed material from returning to said mouth (26), ie when passing through the latter it is grasped by the blades of the first axis and then throws towards the subsequent axes, promoting controlled impacts on the product, enough so that it does not become tangled in the machine and also causes the grain to loosen in relation to the branches, consequently, at this stage part of the material is passed through the sieves (2 9-30).

As already stated, (see Fig. 29) the machine includes a set of vibrating screens, a shorter upper (29) and a longer lower (30), the first of which ends under the suction box (4). , thus defining another cleaning phase, because in this all impurities larger than the grains (branches, leaves and others) are removed, allowing the passage of the grains and smaller impurities to the second sieve which, in turn, also passes under the suction boxes (4) and ends over the clean grain transverse transport chute (31).

As also shown in Figures 30 to 33, the vibrating screens 29-30 are in the form of overlapping rails with their respective side walls 95 and rear 96 through which they are aligned with one another. with a certain distance and fixed suspended by four flexible mounts (97), which have their lower ends fixed on the frame (1), or more precisely on the spars (7) and also triangular lateral supports (98) also join the two sieves (29 - 30), where these supports are support points for the ends of an axis (99), where a vibrating device (100) is coupled, consisting of a triangular part (101) which, on the one hand, is coupled said axis (99) while its apex culminates in a coupling part (102) which is an integral part of a cam (103) mounted on another transverse axis (104), also biased in the frame (1), where one of its ends receives gear (105 qu and by means of chain (106) is coupled to another gear (107) of the motor drive assembly (23). Therefore, the set described above allows the final cleaning to be performed, ie impurities not passing through the upper sieve (29) are sucked into (4), consequently, what passes to the second sieve are grains and other small impurities, where the lighter ones are also aspirated at their end, while smaller particles fall to the ground after passing through the second sieve (30), and at this point only the clean beans of coconut coffee are conveyed to the transport chute (31).

As shown in figures 34 and 35, the transport rail 31 is positioned at the end of the frame 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 yet, this outlet has its upper part equipped with a tilting lid (109) for inspection and cleaning, below said whole transport rail (31) 36, 37 and 38, showing in detail that it internally has a conveyor thread (110) and its axis (111) which, in turn, has its ends biased in the frame (1), wherein one of them is extended enough to also form the drive shaft of the clean grain tank elevator (32) and to this end one of its ends receives a gear (112) which by means of chain (113) constitutes a continuation. of the motor drive assembly (23) that I pass u by the stirring assembly (28). Therefore, the above assembly, that is, the transport chute (31) has the function of receiving only the clean grains, since the final impurities have either been sucked in by the assembly (4) or eliminated by the outlet (108), leaving for behind clean grains that pass through the sieve (30) and fall into the transport chute (31) to be sent to the clean grain mug elevator (32).

Figures 39 to 41 show the constructive details of the clean grain tank elevator (32), which consists of a slightly inclined tower (114) of plates including inspection caps (115) and rounded lower end (116) axially aligned with the chute (31) to receive the clean grain of the latter, as well as in the center of that rounding (116) passes that shaft (111) which, together with another upper one (117), receive gears (118-119) for a chain (120) along which mugs (121) are distributed, oriented to overturn by the rounding (116) where they are loaded upon unloading and, when they reach the upper end of the tower (114) they overturn to be discharged into the spout ( 33) where the clean grains are led to the bucket (34).

The spout (33) has a rectangular end or spout (122) that matches the width of the dump bucket (34), this spout is fixed directly over the corresponding edges of the dump bucket (34), so that both said spout (33) has the opposite side or inlet mouth defined by a collar (123) that fits by simply seating on the upper end of the tower (114) of the tank elevator (32). ).

Tilt bucket 34 is illustrated in detail in FIGS. 42 and 43, where it is shown that it initially comprises a pair of gantry beams, one on each side (124), each formed by two tubes. inclined, the upper ends of which are joined and are a point of bearing for an axis (125), while the lower ends of the beams are fixed on the mullions (12) of the complementary structure (3) of the structure (1), so that said The shaft (125) is positioned substantially high and out of the right side of the machine while maintaining parallelism as it is a pivot point and is integrated with the corresponding edge of the bucket (34) which in turn is defined with a quadrangular bottom and smooth or sieve-shaped walls, where the front and rear walls are vertical, while the side walls are substantially sloping, forming a mouth substantially larger than the base, mouth is under to which that elevator spout (33) is fixed, while on the opposite side is articulation with the shaft (125), between these two points, or more precisely in the first third of the width of the bucket mouth (34) a cross-member whose ends constitute an axis 126 for the upper ends of hydraulic cylinders 127 on each side whose lower ends are biased in supports 128 on the complementary structure 3 so that said cylinders (127) may extend as shown in figures 44 to 46, whereby the maximum extent of said hydraulic cylinders (127) at the moment the bucket is discharged. Of course such unloading can occur under various conditions, such as, for example, inside another bucket or body of a clean grain transport vehicle, but regardless of such aspects, bucket unloading (34) is carried out rapidly. and efficient.
