Abstract

ARRANGEMENT IN GATHERING MOUTH FOR BEAN AND PEANUT HARVESTER, comprising a gathering roll (16) which, rotating at an anticlockwise direction, gathers the branches of bean or peanut that are already pulled out and bunched, throwing them upwards and backward to the dragging roll (37) or above the rolls (55-54) and, afterwards, to the dragging roll (37) that, in turn, lead s the gathered product to the press cylinder (23), so that this movement itself makes the land and some other small particles to be removed by the sieve or screen ( 14) of the mout h (9);said press cylinder (23) receives and removes the product from the mouth and lead it to the beating cylinder (28) which, in turn, works in the longitudinal-horizontal direction and its tracking system is axial, thereby allowing to speed up or to delay the flow of the product to be trodden out, carrying it through the screen (27), which works for allowing grains and small particles to pass over, stopping the large particles that a re c arried to the outlet of straw placed in the right back side of the machine. On said set, t he vibrating sieve (26) is placed, which receives the trodden out product together with t he small particles, such as straw and land, and, through its long extension, removes the land by an outflow system and allow the product ready for being cleaned by a stream of air (30). The product entirely cleaned is carried to the gutter (31-33) and, from this point on, the chained container lift (34) carries the product entirely cleaned to the bulk section (36).

Description

PROVISION INTENDED IN RECOVERY MOUTH FOR JEWISH AND PEANUIT HARVEST State of the art The present utility model refers, more specifically, to technical improvements specially developed to characterize the most effective means applied to the harvester mouth of a harvester, be it the same as beans, peanuts or any other grain, so that said harvester can collect plants previously torn and crowded and, subsequently, said harvester can also perform, more effectively, the process of complete cleaning of the grains, separating them from the other disposable parts of the plant. Today there are several agricultural machines and implements with collector mouths specially designed for the harvesting of grains, especially peanuts and beans, as demonstrated by the Brazilian applications MU 7801088 DEL 08/06/1998, MU 7900686 of 3/27/1999 and MU 7900789 OF 05/21/1999, all of them with title of "disposition introduced in bean and peanut harvester, and PI 1647 of 4/19/2000 -" branch harvester set. "The harvesters indicated are generally equipped with similar collecting mouths, also formed by a real mobile entrance tunnel, with a relatively rectangular cross section and elongated in the longitudinal direction of the machine, even with a slight backward narrowing, where its rear end is articulatedly fixed to the structure and, under this condition, it is suspended by mechanical means, the latter being a threaded element with a manual nut and a spring for adjusting the working height, while the facet lower said tunnel has its wall in the form of a static sieve, as it also has a bearing in the form of a supporting guide roller which, in turn, makes it possible for said tunnel or its boc To lower, the irregularities of the floor are accompanied in a high way, because, next to said mouth, a pick-up roller with tips is mounted transversely. 52/285 pickers, which move alternately, being more exposed in the lower part of the roller, while in the upper part they are more collected and, thus, this retractable effect, with the rotation of the assembly through transmission, allows to collect the branch and throw it into the tunnel and on its sieve, where the drag continues through a conveyor belt, which cooperates to capture the branches and drag it over said sieve and dispense them inside a compartment transversely existing in a previous part of the chassis, where a compressor cylinder is housed, which has a configuration similar to the pick-up roller, but, in this case, with a smaller number of retractable tips, as well as in its external part includes a conveyor propeller, which cooperates in the driving from the branches to the entrance of another compartment longitudinally positioned on the chassis, compartment this limited interior e by a vibrating screen and by a tunnel in the form of sieve or mesh, being inside this and above the first a beating cylinder with a propeller with "L" and pallet tips, which cooperate to beat the branches and , at the same time, to drive them back, where the beating tunnel and the vibrating screen are in communication with two different parts: the sieve in a right lateral outlet, while the vibrating screen is in communication with a suction duct that, in addition, of having regulation of air intake and mancal extruder, also has in the upper part a purifying fan of the threshed material and even said sieve also ends in a transverse collector box of almost clean grains with a conveyor thread which, in turn, ends at a point of lowering and, from this point upwards, a chain elevator with jugs is developed, the upper part of which has a prolongation to the rear in the form of a ramp. ally, ends in an existing bulk compartment on the cart, where the completely clean grains are dispensed. Therefore, it can be noticed that, in the collecting mouth of the previous models, the plants are picked up by a tunnel that, at its front end, has a pick-up roller and, subsequently, the same tunnel is equipped with a conveyor belt. the branches to the compressor cylinder. This system logically presents its advantages, yet, with the passing of time, it was observed that it could be perfected, since its operation by tape did not cause the desired effects in the agitation of the plants.

Objectives of the present model The first objective of the model is the configuration of a modified tunnel, the sieve being kept in its lower part. The second objective of the model is to completely eliminate the conveyor belt by a rotating intermediate piece for dragging the branches, so that it can, on the one hand, fish the branches collected by the pick-up roller and, on the opposite side, drive said branches for the compressor cylinder. Under this condition, the agitation of the branches, beyond being more efficient, produces a new technical effect, because said rotating piece of drag presents several pieces in the form of four-pointed arched stars and, with this, also occurs an intimate work with the branches , shaking it for looseness of the earth and other waste that is discarded by the sieve. The third objective of the model is to adopt a new constructive arrangement for the pick-up roller, since this, in spite of being the same as that described in the application PI 1647 of 04/19/2000, entitled "Tree Harvester Set", was modified with the addition of arched rules or of spring equally arched between the tortuous claws (fingers), attributing to the set an aspect of rotating combs and, thus, this collection set, during its operation, proved to be much more efficient in relation to the previous models, then, with said construction, the pickup roller went on to present its diameter or its ordinary cylindrical surface defined only by the radial exposure of the claws, which are responsible for picking up the branches and for throwing the same to the intermediate trailing roller, consequently, the branches remain substantially loose on the pick-up roller, avoiding those piles that could eventually decrease Check the efficiency of the pick-up roller operation.

For a better understanding of the present utility model, a detailed description thereof is made, referring to the attached drawings, where: FIGURE 1 represents a side view of the harvester with the collecting mouth; FIGURE 2 shows another side view, but partially in section, highlighting the operation of the combine; FIGURE 3 shows a view of the pick-up roller in isolation; FIGURE 4 is a side view partly in section, showing the collecting mouth; FIGURE 5 shows a view of the cut A- A; FIGURE 6 represents a view of the cut B-B; FIGURE 7 is a left side view of the collecting mouth; FIGURE 8 shows a front view of the collecting mouth; FIGURE 9 is a side view in section of the collecting mouth, highlighting its internal rolls; FIGURE 10 shows a left side view of the collecting mouth and a sectional view of its height adjustment device; and FIGURES 11 through 17 are analogous to the previous views, but highlighting some constructive variations of the collecting mouth. According to these illustrations and in their details, the present utility model, disposition introduced in collecting mouth, was developed to be used with different harvesters, such as that illustrated by figures 1 and 2, by means of which it is observed that it is of the type classified as trailing and, for this, it includes a first structural part defined as chassis or cart (1), duly supported on a pair of wheels (2), as also its front part is substantially elevated and in the shape of a true hitch (3), but oriented forward and with some declivity, where its end presents two details, in which the first is a vertical foot rest (4) and the second is a universal trailer hitch (5), before which said lance presents a slope and, from this point to the rear, configures the means (6) for the assembly of the hydraulic assembly (7) and, below it, also constitutes a conduit with internal resources for the assembly of a cardan shaft (8) that, on the one hand, it is intended to be coupled to the power take-off of the tractor, while on the opposite side is interlinked with a transmission system (not illustrated) by belts, chains, pulleys, gears and all sorts of necessary components for interligation, rotation and actuation of the different moving parts of the machine, but said drive system may have any configuration compatible with the assemblies to be driven. Still referring to FIGS. 1 and 2, above the drawbar (3) and the detail (6) there is positioned a pick-up mouth (9) practically in the form of a real mobile entrance tunnel, with a somewhat ordinary cross-section rectangular and elongate in the longitudinal direction of the machine, even with slight narrowing to the rear, where its rear end is articulated (10) fixed to the corresponding end of the chassis (1), where it is kept suspended by means of mechanical means (11) and (12), the latter being a threaded element with manual nut (13) and a spring for adjusting the height of the work, while in the lower facet said tunnel presents its wall in the form of a static sieve (14), as well as it has lateral support wheels (15) in its front part, so that said mouth (9) can accompany in a high way the irregularities of the floor because, together with such a mouth, a roller is mounted transversely. (16), described and claimed in MU 7801088, that is, as illustrated in Figures 3, 4, 5 and 6, is constituted by a tubular body (17) and tubular mounting tips (18), these and the first traversed by a static axis (19) with an eccentric intermediate part (20) and along which are distributed several pick-up tips (21) which, at one end, are mounted in the manner of connecting rods in the eccentric part of said axis, while the opposite ends pass through existing holes in the tubular body (17) where these tips move alternately, being more exposed in the lower and upper part of the roller, while in the back are more collected and, thus, this effect retractable that occurs gradually, with the rotation of the assembly through the transmission (22) (Fig. 7), allows the branch R to be collected and thrown into said tunnel or mouth (9) and on its sieve (14), where the drag continues so that the branch (R) can pass over said sieve (14) and dispense it inside a compartment transversely existing in the anterior part of the chassis (1), where a compressor cylinder (23) is housed, seen with details in figure 2, by means of which it is observed that it presents a similar configuration to the pick-up roller, but, in this case, with a smaller number of retractable tips, as well as its external part includes a conveyor propeller (24), which cooperates to drive the branches to the entrance of another compartment (25) longitudinally (FIGS. ) positioned on the chassis (1), compartment is delimited internally by a vibrating screen (26) and by a tunnel in the form of sieve or mesh (27), being inside this and above the first a beater cylinder ( 28), which cooperates to beat the branches and, at the same time, drive it backwards, where the beating tunnel and the vibrating sieve are in communication with two different parts, that is, the sieve (27) ends in a right lateral exit while the vibrating sieve ( 26) is in communication with a suction duct (29) which, in addition to having air intake regulation, also has a fan (30) for purifying the threshed material at the top, and said screen (26) still also ends in a box cross-cutter of almost clean grains (31) with a conveyor thread (32) which, in turn, ends in a rebate point (33) and, from this point up, develops a chain elevator with jugs (34) , whose upper part has a prolongation to the rear in the form of a ramp (35) that, finally, ends or empties into a bulk carrier (36) existing on the cart. With reference to figures 8 and 9, the present utility model is characterized by, initially, the tunnel or mouth (9) having an intermediate trailing roller (37), whose axis (38), as shown in figure 7, is synchronized together with the lateral transmission (22), where a chain (39) with extruder (40) interlinks the gears (41-42) of the pick-up roller (16) and the intermediate drive roller (37), as well as, the opposite side, seen in figure 11, there is also a transmission by gear and chain between the compressor roller (23) and the drive roller (37) which is still defined by star-shaped discs (43) with curved tips, as also between said disks is a detaching comb (44), ordinarily vertical and slightly arched, positioned on the rear part of the intermediate trailing roller (37), where it has the function of releasing the branches after being dragged. Still referring to Figure 7, the sieve (14), in addition to having a variable mesh, its lower part, when viewed from the side, presents a certain sinuosity, accompanying the lower profile of the intermediate roller (37) and the lower profile of the pick-up roller (16). The model in question also has an important feature, seen in detail in figures 8 and 9, by means of which it is observed that the pick-up roller (16) is constituted, as already pointed out, by several sets of pick-up tips (21). ), where each set is preferably formed by six radial tips, constituting a circle (21 A) of tips. In the model in question, the characteristic or novelty introduced in said pick-up roller is precisely the arrangement of a set of separators (45), each formed by a sheet rule bent in "U", arranged between each circular assembly (21 A ) of tips (21), so that the rounded part of each separator (45) can be turned forwards, while its ends are turned back, where they are fixed by suitable supports (46). The separators (45) were created to define a semicircular frontal surface and, with this, the branches slide more easily backwards and in the direction of the intermediate dragging roller (37), as also the entanglement of said branch in the area of the pick-up roller (16). Still with reference to figures 8, 9 and 10, the collecting mouth has as a characteristic the fact that between it and each wheel (15) there is an intermediate set of height adjustment (47), formed by a telescope (48) , whose lower end is linked to the supporting structure (49) of the corresponding wheel (15), while the upper end includes support (50) and spring (51) fixed on the side of the collecting mouth (37), where said set is crossed by a threaded element (52) with the respective crank (53), thus configuring the means necessary to increase or decrease the course of said telescope (48) and, consequently, it is possible to establish an ideal working height for the roller dustpan (16). Figures 11 to 17 show similar views to the previous ones, but in this case some constructive variations of the mouth in question are highlighted, being that, in the first, the spacers (45) are formed by round bars also arched and, in this case, the pick-up roller (16) preferably has eight retractable tips (21). The second constructive variation is illustrated in Figure 15, by means of which it is observed that the distance between the pick-up roller (16) and the intermediate trailing roller (37) is substantially greater, so that in this space other two drag rollers, one cylindrical (54) and one sixth (55), which are synchronized between them, as illustrated in figures 16 and 17, by a complementary transmission system (56) mounted on the right and left sides of the mouth (9), where said transmission systems are formed by gears, chains and belt extruder, so that said rollers (54-55) , as well as the pick-up roller (16) and the take-up roller (37) can be synchronized between themselves and with the power take-off of the tractor (not shown). The operation of the harvester in question is very simple, that is, the pick-up roller (16), turning in the counterclockwise direction, picks up the bean or peanut plant that has previously been pulled out and crowded, throwing them up and back in the direction of the roller of drag (37) or on the rollers (54-55) and, subsequently, for the drive roller (37) which, in turn, transfers the collected product to the compressor roller (23) This movement already causes the soil and some small dirt are dispensed by the sieve or mesh (14) of the mouth (9). The compressor roller (23) has the function of receiving and removing the product from the mouth and transferring it to the beater cylinder (28) which, in turn, works in the longitudinal horizontal direction and its threshing system is axial, allowing to accelerate or retard the flow of product to be threshed, passing it through the shirt in the form of mesh (27), which has the function of letting pass the grains and minor impurities, such as fine straw and earth and, in its long extension, eliminates the soil by emptying system and leave the product ready to receive cleaning by the air flow (30). The completely clean product is taken to the box (31-33) and, from this point, the jug elevator (34) transports the completely clean product to the bulk carrier. As can be seen, the improvements introduced in the present harvester, after what was shown and illustrated, define a new constructive arrangement, substantially more advantageous than previous models because, with such modifications, the stages of collecting and cleaning the product are made more precisely, that is, the improvement introduced in the pick roller allows it to turn the opposite in relation to the previous model, that is, the branches are suspended and thrown up and back, which does not occur in previous models , where the movement of the branches is on the contrary and, with this, the amount of dragged earth is substantially smaller, as also the fact of the branches being lifted when the cleaning process begins, releasing the earth that eventually accompanies the branches. Continuing, the roller (37) accompanied or not by the rollers (54-55) also confers an additional agitation for the branches, releasing still more certain dirt, mainly dirt. After this, the separation or cleaning process of the grains is equal to the aforementioned models.
