Description

TECHNICAL FIELD The present invention relates to a residue discharge mechanism of a bean threshing machine that removes pods from beans and discharges the residue.

JP 2020-39304 A

In the bean threshing machine described in Patent Document 1, peanut stocks dug up in a field and dried in rows are picked up, threshed, and harvested while traveling. When the stock to be fed into the threshing machine is sufficiently dry, the stems and leaves can be finely pulverized by the threshing cylinder and completely discharged as residue from the residue discharge port without remaining in the residue discharge port. On the other hand, since it takes a relatively long time to sufficiently dry the peanut stocks, it is desired to thresh the peanut stocks and harvest the peanuts as soon as possible.

However, if the stalks that are not sufficiently dried are threshed, the stems and leaves cannot be pulverized finely by the threshing cylinder, and the residue may become large and cannot be blown away by the wind from the winnow. In particular, the dried stocks tend to be unevenly dried, and there is a high possibility that many large residues will be generated in the stems and leaves with high moisture content. Therefore, there is a problem that the residue remains at the residue discharge port, the work is interrupted, the efficiency of the threshing is lowered, and an auxiliary worker is required, so that the residue cannot be discharged satisfactorily.

The present invention has been made to solve such problems, and when the beans that are unevenly dried are threshed and the residue separated from the beans is discharged, the residue may stay at the residue discharge port.

A pod removing part 4 located on the rear side of the body of the plant picking part 3 has a pod separating mechanism 43 for separating the pods 91 from the peanut stalks 9, and sorts out the pods 91 separated from the peanut stalks 9 from the residue 92 by wind force. It is equipped with a wind sorting mechanism 44 and a pod recovery mechanism 45 that recovers the sorted pods 91 and collects them in a pod recovery box (not shown) through the pod recovery pipe 42 .

The pod separating mechanism 43 includes a cylindrical squeegee drum 47 that rotates around a rotation axis 46 that extends horizontally in the vehicle width direction, and a receiving net 48 that is arranged horizontally in the vehicle width direction below the scramble drum 47. and The receiving net 48 has an arc-shaped curved shape centering on the rotation axis 46 of the squeezing cylinder 47, and faces the lower part of the outer peripheral surface 47a of the scouring cylinder 47 at a constant interval. there is

The receiving net 48 is a net having a mesh size through which the peanut pods 91 can pass. An input port 49 is provided between the outer peripheral surface 47a of the handling drum 47 and the edge of the receiving net 48 on the front end side of the vehicle body. be done.

As shown in FIG. 4(a), a large number of handling teeth 51 are attached to the outer peripheral surface 47a of the handling cylinder 47. As shown in FIG. The tines 51 protrude radially from the outer peripheral surface 47a, and feed the peanut stalks 9 in a direction perpendicular to the axis of rotation 46 along between the shaving cylinder 47 and the receiving net 48. The pods 91 are separated. A large number of projections 52 for discharging residue are attached to the outer peripheral surface 47 a of the scraping cylinder 47 . The residue discharge projections 52 also project radially from the outer peripheral surface 47a, and serve to scrape out the residue 92 remaining between the scraping cylinder 47 and the receiving net 48 as the scraping cylinder 47 rotates.

The edge of the receiving net 48 on the rear side of the vehicle body extends almost to the height position of the rotation axis 46 of the wrapping cylinder 47. Here, a residue discharge guide plate 48a is bent obliquely downward toward the rear of the vehicle body and extends. formed. On the vehicle body rear side of the residue discharge guide plate 48a, a residue discharge rotary vane 53 extending horizontally in the vehicle width direction is arranged. The pods 91 and fine debris 92 separated by the tines 51 pass through the catch screen 48 and fall. Residues 92 that have not fallen from the receiving net 48 but have been sent out to the residue discharge guide plate 48a at the rear end thereof are sent out by the residue discharge rotary vane 53 and discharged horizontally rearward from the residue discharge port 41a. . It should be noted that the term “horizontal” as used herein is not limited to strictly horizontal, but includes substantially horizontal as long as it is ejected rearward.

In the beans threshing machine 1 according to the embodiment, on the outer peripheral surface 47a of the threshing drum 47, the threshing teeth 51 are arranged at constant angular intervals along the circumferential direction. At each angular interval, the treatment teeth 51 are arranged in a row along the direction of the rotation axis 46 at regular intervals.

On the other hand, the residue discharging projections 52 are arranged on the outer peripheral surface 47a of the scraping cylinder 47 so as to be positioned between the rows of the scraping teeth 51 in the circumferential direction. At each position in the circumferential direction, the residue discharge projections 52 are arranged in a zigzag pattern with respect to the treatment teeth 51 along the direction of the rotation axis 46 at intervals wider than the treatment teeth 51. .

As shown in FIG. 4(b), the tines 51 consist of a mounting plate portion 51a attached to the outer peripheral surface 47a of the threshing cylinder 47 and a tapered base standing perpendicularly from one end of the mounting plate portion 51a. and a profiled, flat plate-like treatment tooth portion 51b. Mounting holes 47b are formed in the outer peripheral surface 47a of the handling drum 47 at positions for mounting the teeth on the mounting plate portion 51a by means of bolts (not shown). It is fastened and fixed to the outer peripheral surface 47a of the handling cylinder 47 by bolts shown in the figure.

The treatment tooth 51 is attached so that the treatment tooth portion 51b faces the circumferential direction of the outer peripheral surface 47a. In addition, in the treatment tooth portion 51b, an inclined end surface 51c facing forward in the rotation direction of the treatment cylinder 47 is rectilinearly provided with a receding angle θ. That is, the inclined end face 51c is positioned rearward in the rotational direction at an angle of 25 to 35 degrees with respect to a normal line (radius r) drawn at a position intersecting the inclined end face 51c on the outer peripheral surface 47a of the handling drum 47. slopes linearly to The beans threshing machine 1 according to the embodiment is inclined at an angle of 30 degrees.

As shown in FIG. 4(c), the residue discharge projection 52 is composed of a fixing metal fitting 52a having a threaded portion to be fixedly attached to a mounting hole 47b formed in the outer peripheral surface 47a of the scraping cylinder 47, and the fixing metal fitting 52a. and an elongated elastic rod-like body 52b of circular cross-section which is inserted and secured to the cylindrical portion of the housing. The elastic rod-shaped body 52b is molded from a material such as urethane resin.

The projection length of the residue discharging projection 52 is set so that the tip of the elastic rod-shaped body 52b is pressed against the receiving net 48 with a predetermined pressing force. Therefore, in the state where it is attached to the handling cylinder 47 and used, the elastic rod-like body 52b is slightly curved rearward in the rotation direction, as indicated by an imaginary line 52A in FIG. While being pressed against the surface, it slides along the inner peripheral surface.

Thus, in the pod threshing mechanism 4 of the beans threshing machine 1 according to the embodiment, the residue discharge projections 52 for scraping out the residue 92 remaining between the threshing cylinder 47 and the receiving net 48 are arranged. The discharging projection 52 is dimensioned so that the tip portion of the elastic rod-like body 52b contacts the receiving net 48 and forms a slightly curved state in a state of being attached to the outer peripheral surface 47a of the handling cylinder 47. ing. Further, as the handling tooth 51, a plate-like tooth having a receding angle of 30 degrees on its front end face is used.

During the hulling operation, the residue 92 gradually stays between the pallet 47 and the receiving net 48, and at the same time, the residue 92 is scraped out by the residue discharge projections 52. Therefore, retention of the residue 92 can be greatly reduced as compared with the conventional art.

In addition, in general serrated teeth for soybeans, the rise angle from the outer peripheral surface of the trough cylinder is almost a right angle, and because of the arch shape using a round bar, residues 92 are left on the serrated teeth themselves during work. It tends to get entangled, and as a result, the amount of the staying residue 92 may be increased. On the other hand, the flat, linear treatment tooth 51 having the receding angle θ of 30 degrees can reduce the amount of the residue 92 entangled.

The present inventors conducted a test using a tester equipped with the residue discharging projections 52 and a flat tooth 51 having a rectilinear receding angle .theta. of 30 degrees. As a result, the amount of peanuts remaining in the machine can be kept low relative to the amount of peanut stocks input, and even when the water content of the peanuts is high, the amount of residuals in the machine can be reduced by adjusting the machine operating conditions such as the handling cylinder. became clear.

Next, with reference to FIGS. 2 and 3, the wind sorting mechanism 44 and the pod collecting mechanism 45 incorporated under the receiving net 48 will be described. The wind sorting mechanism 44 sorts pods 91 having a relatively large specific gravity by wind sorting from the pods and fine residue 92 that pass through the receiving net 48 and fall. The pods 91 sorted by the wind sorting mechanism 44 are collected by the pod collecting mechanism 45 located at the bottom thereof. The fine residue 92 pulverized by the threshing cylinder 47 in a completely dried state is blown away by the wind from the wind sorting mechanism 44 and discharged to the rear of the bean threshing machine 1 from the residue discharge port 41a.

The wind sorting mechanism 44 is provided with an oscillating sieve plate 55 having a rectangular profile located below the receiving net 48 . The swingable sieve plate 55 is arranged substantially horizontally toward the rear of the vehicle body at a position below the receiving net 48 . As shown in FIG. 5(a), the swing type sieve plate 55 has a receiving plate portion 55a for receiving the pods 91 and the residue 92 that have passed through the receiving net 48 and fallen, and a receiving plate portion 55a on the rear side of the vehicle body. and a sieve portion 55b formed continuously at the end.

As shown in FIGS. 2 and 3, the upper surface of the receiving plate portion 55a is a corrugated plate surface in which corrugated unevenness inclined toward the rear of the vehicle body is formed at a constant pitch toward the rear of the vehicle body. In the sieve portion 55b, elongated metal rods 55c of a constant length, which are slightly inclined upward toward the rear of the vehicle body, are arranged at constant intervals in the vehicle width direction. It's becoming The rows of the metal rods 55c are formed in a plurality of rows toward the rear of the vehicle body, four rows in the illustrated example. In addition, the upward inclination angle of the metal rods 55c forming the sieve meshes is set to increase toward the rear of the vehicle body. The width of each sieve mesh is set to a dimension through which the pods 91 can pass.

The rocking type sieve plate 55 is given a rocking motion to send out the pods 91 and the like received by the receiving plate portion 55a in the feed direction toward the sieve portion 55b (the direction toward the rear of the vehicle body). Owing to the swing motion of the swing-type sieve plate 55, the pods 91 and foreign matters 92 on the receiving plate portion 55a are sent in the feeding direction to reach the sieve portion 55b, and the pods 91 fall from the sieve meshes of the sieve portion 55b. do.

The swinging mechanism supports the upstream end portion of the receiving plate portion 55a of the swinging sieve plate 55 in the feed direction, and has an eccentric rotary shaft 56a that swings vertically and in the feed direction with a predetermined amplitude. ing. Further, the swinging mechanism causes the downstream end portion of the sieving portion 55b of the swinging sieve plate 55 to follow the swinging motion of the upstream end portion, and moves up and down and back and forth with an amplitude smaller than the swinging motion of the upstream end portion. It has a swing link 56b which is suspended in a swingable state.

The lower end of the swing link 56b is connected to the downstream end portion of the swing type sieve plate 55 so as to be rotatable about an axis extending horizontally in the vehicle width direction. The upper end of the rocking link 56b is attached to a fixed position above the rocking sieve plate 55 so as to be rotatable about a rocking center axis extending horizontally in the vehicle width direction.

With this swinging mechanism, as shown in FIGS. 5(b), 5(c) and 5(d), the eccentric rotating shaft 56a rotates to rotate the upstream end 55d of the swinging sieve plate 55. oscillates up and down and back and forth with a large amplitude, and following the oscillation, the downstream end 55e side oscillates up and down and back and forth with a smaller amplitude. It was confirmed that the pods 91 and the residue 92 can be sent out more efficiently than when the rocking type sieve plate 55 is rocked up and down and back and forth with the same amplitude as a whole using a general rocking mechanism.

As shown in FIGS. 2 and 3, below the oscillating sieve plate 55, pods 91 falling from the sieve portion 55b are arranged upstream and downstream in the feeding direction in order to guide the pods 91 falling from the sieve portion 55b to the pod recovery mechanism 45. An upstream inclined guide plate 57 and a downstream inclined guide plate 58 are arranged. The upstream slanted guide plate 57 is slanted downward toward the rear of the vehicle body, and the downstream slanted guide plate 58 is slanted downward toward the front of the vehicle body. The lower ends of these upstream inclined guide plate 57 and downstream inclined guide plate 58 extend to a pod lateral feed gutter 61 extending horizontally in the vehicle width direction of the pod collecting mechanism 45 .

A winnow fan 59 is arranged on the front side of the vehicle body of the upstream inclined guide plate 57 . A blowout port 59a of the fan 59 opens toward the rear of the vehicle body at the upper edge portion of the upstream inclined guide plate 57. As shown in FIG. An upper edge of the downstream inclined guide plate 58 on the rear side of the vehicle body extends to the residue discharge port 41a. A shield plate 60 is arranged above the downstream inclined guide plate 58 . The shielding plate 60 extends from a position above the horizontal pod feed gutter 61 of the pod collecting mechanism 45 to a position halfway on the rear side of the vehicle body along the surface of the downstream inclined guide plate 58 .

In the sorting operation of the wind sorting mechanism 44, the swing type sieve plate 55 swings to send out the pods 91 and the residue 92 from the feed plate portion 55a toward the rear side sieve portion 55b. On the lower side of the oscillating sieve plate 55, the air blown from the outlet 59a of the winnow fan 59 flows along the surface of the upstream inclined guide plate 57, and the lower side of the downstream inclined guide plate 58 flows. It is guided obliquely upward toward the sieve portion 55b of the rocking sieve plate 55 by the shielding plate 60 covering the portion.

A part of the wind goes directly to the residue discharge port 41a, and the rest flows to the residue discharge port 41a after blowing upward through the screen meshes of the screen portion 55b. The pods 91 and the residue 92 sent to the sieve portion 55b are wind-sorted by the specific gravity difference by such a sorting air stream.

The pods 91, which have a relatively large specific gravity, fall from the sieve meshes of the sieve portion 55b onto the upstream inclined guide plate 57, the shielding plate 60, or the downstream inclined guide plate 58. Residues 92 such as roots, stems, leaves, etc., which have a relatively small specific gravity, are carried by the sorting air flow that blows up through the sieve mesh, are blown up from the sieve portion 55b, and are blown up from the residue discharge port 41a toward the rear of the vehicle body. Discharge horizontally.

Many of the pods 91 that have fallen onto the upstream inclined guide plate 57 slide down the surface and are collected by the pod horizontal feeding gutter 61 for collecting pods. The pods 91 that have fallen onto the shielding plate 60 ride on the sorting airflow that flows upward along the surface of the shielding plate, move to the upper end of the shielding plate 60, and fall from there to the downstream inclined guide plate 58, where , and reaches a pod horizontal feed gutter 61 for collecting pods. Along the upper surface of the shielding plate 60, a sorting airflow is blown upward toward the sieve portion 55b.

The fine residue 92 falling through the screen mesh of the sieve portion 55b is blown up by the sorting air flow, so that it does not fall into the pods horizontal feeding gutter 61 for collecting pods. The shielding plate 60 sorts and separates the pods 91 that have fallen through the sieve mesh and the relatively fine residue 92 with high accuracy.

Next, the pod collecting mechanism 45 is provided with a blower fan (not shown) arranged at one end of the pod horizontal feeding gutter 61 for collecting pods. The pods 91 collected in the horizontal pod-feeding gutter 61 for collecting the pods are sent out in the vehicle width direction by the wind flowing through the horizontal pod-feeding gutter 61 by the wind blown from the blower fan. The end of the pod horizontal feed gutter 61 is connected to the lower end of the pod recovery pipe 42 . The pods 91 sent out through the pod horizontal feed gutter 61 are collected in a pod collection box (not shown) placed on the working floor plate 7 via the pod collection pipe 42 .

The residue discharging mechanism 100 has a rotating shaft 101 and a plurality of rotating bodies 100a, 100b, 100c, 100d, and 100e fixed to the rotating shaft 101 so as to be integrally rotatable. The rotating shaft 101 is arranged so as to extend along the width direction of the residue outlet at a position adjacent to the residue outlet.

As shown in FIGS. 2 and 3, the rotating shaft 101 is positioned above the residue discharge port 41a for discharging the beans residue 92 generated by threshing, and the axis of the rotating shaft 101 is orthogonal to the discharge direction of the residue 92. are arranged along the width direction of the residue discharge port 41a. The rotating shaft 101 is rotatably supported by the shelling section housing 41, and is rotated at a predetermined speed (rpm) in the residue discharge direction shown in FIGS. 2 and 3 by a driving device (not shown).

The plurality of rotating bodies 100a, 100b, 100c, 100d, and 100e are arranged at intervals in the axial direction of the rotating shaft 101, as shown in FIG. 6(a). The residue discharge mechanism 100 has a function of rotating the rotating bodies 100a to 100e in a direction to scrape out the residue 92 from the residue discharge port 41a, and forcibly discharging the residue 92 from the residue discharge port 41a toward the rear in the discharge direction. . In this embodiment, the case where the number of rotating bodies is five will be described as an example, but the number of rotating bodies may be other than five.

As shown in FIG. 6B, each of the rotating bodies 100a, 100b, 100c, 100d, and 100e may be arranged such that the tines 102 are gradually shifted at a constant angle in the direction of rotation, As shown in FIG. 6(c), each tine 102 may be arranged so as to be randomly shifted at an arbitrary angle.

7 and 8, the rotating body 100a includes a fixed member 103 fixed to a rotating shaft 101, and a rod-shaped member having a proximal end fixed to the fixing member 103 and protruding radially outward from the rotating shaft 101. It has tines 102 . A plurality of tines 102 are provided so as to radially extend from the rotating shaft 101 . At least one or more tines 102 may be provided in each of the rotating bodies 100a to 100e. A plurality of fixing members 103 are provided at predetermined intervals in the axial direction of the rotating shaft 101 .

Each tine 102 is made of a rod-shaped elastic member having a circular cross section, as shown in FIG. 9(a). As shown in FIG. It is fastened to the fixed member 103 by the fastening member 104 at the offset position. More specifically, each tine 102 extends along the tangential direction of the rotating shaft 101 at a position spaced apart from the rotating shaft 101 in the radial direction, and the base end portion of the tine 102 is arranged on the front side of the rotating shaft 101 in the rotating direction. , tip portions of the tines 102 are arranged on the rear side of the rotating shaft 101 in the rotating direction.

By arranging each tine 102 at a position in which the base end portion is offset with respect to the rotating shaft 101, the space for fastening the four tines 102 to the fixing member 103 becomes relatively wide, and the degree of freedom in fastening is increased. increases. The four tines 102 are arranged at equal angular intervals. Examples of elastic members used for the tines 102 include glass fiber poles and metal rods.

The tines 102 enter a region facing the residue discharge port 41a from a region above the residue discharge port 41a (a region adjacent to the residue discharge port 41a) by rotation of the rotary shaft 101, It moves in the discharge direction (backward in this embodiment) in which the residue is discharged. The tip portion of each tine 102 is deformed by interfering with the tip portion of the frame 41b provided in the pod threshing housing 41 of the bean threshing machine 1 by rotation, and further rotated to deform the tip portion of the frame 41b. It is configured to pass through and restore its original shape. Note that the tines 102 according to the embodiment correspond to the residue scraping member of the residue discharging mechanism of the beans threshing machine of the present invention.

As an interference member, the tip portion of the frame 41b contacts the tip portion of the tine 102 at a predetermined rotation angle when the rotating shaft 101 rotates, and is disposed at a position where the contact is released when the rotating shaft 101 rotates further. . The tines 102 are elastically deformed so that the tips of the tines 102 are tilted rearward in the rotational direction in the area above the residue discharge port 41a by contact, and the deformation is restored in the opposing area by releasing the contact. In this embodiment, as shown in FIG. 10(b), the tines 102 are elastically deformed so that the entire tines 102 are bent by coming into contact with the tip portion of the frame 41b.

The tines 102 may be configured in a shape other than a rod-shaped elastic member having a circular cross section. For example, as shown in FIG. 9(b), the tines 102W may be curved rod-shaped elastic members having a circular cross section, or straight tines 102W having a square cross section, as shown in FIG. 9(c). The tines 102K may be made of rod-shaped elastic members.

As shown in FIGS. 7 and 8, the fixed member 103 is formed in a disc shape, and is fixed to the rotating shaft 101 by inserting the rotating shaft 101 into a through hole (not shown) formed in the center. configured to rotate with the The fixed member 103 has eight fastening holes formed near the outer periphery thereof.

Rotating bodies 100b, 100c, 100d, and 100e are configured similarly to rotating body 100a.

Next, the operation of the residue discharging mechanism 100 will be described with reference to FIGS. 10(a), 10(b) and 10(c).
As shown in FIG. 10( a ), the residue discharge mechanism 100 rotates in the direction of the arrow, and the tips of the tines 102 rotate to move the frame 41 b provided in the pod threshing housing 41 of the beans threshing machine 1 . When the tines 102 come into contact with the tip portion and are further rotated, the tines 102 bend downward in a convex shape as shown in FIG. 10(b). More specifically, when the tips of the tines 102 contact the tips of the frame 41b in the region above the residue discharge port 41a, the entire tines 102 bend in the region above the residue discharge port 41a, and the tips of the tines 102 are bent. is elastically deformed so as to tilt backward in the direction of rotation.

When the tines 102 rotate further downward in the curved state, they enter the opposing area facing the residue discharge port 41a, and the contact with the tip portion of the frame 41b is released in the opposing area. Then, as shown in FIG. 10(c), the rotation of the tines 102 is temporarily accelerated by the restoring force of the tines 102 when they are restored, and the residue 92 near the residue discharge port 41a is removed from the residue discharge port 41a. The beans are thrown away toward the rear of the bean threshing machine 1, which is the discharging direction. Subsequently, the tines 102 are restored to their original positions shown in FIG. 10(a), and are bent downward by rotation as shown in FIGS. are continuously flipped off toward the rear of the bean threshing machine 1 from the area facing the residue discharge port 41a.

The residue discharge mechanism 100 according to the embodiment is positioned near the residue discharge port 41a and has a plurality of rotating bodies 100a, 100b, 100c, 100d, and 100e. Each rotating body has a plurality of tines 102 , fixed members 103 and fastening members 104 . The rotating bodies are arranged at intervals in the axial direction of the rotating shaft 101 so that the tines are at the same phase position. With this configuration, the residue to be discharged from the residue discharge port 41a can be forcibly removed from the vicinity of the residue discharge port 41a by applying the rotation and restoring force of each of the four tines 102 in the residue discharge direction. can be scraped out.

In particular, since each tine 102 is formed of a rod-shaped member, the residue 92 to be discharged from the residue discharge port 41a is more likely to reach the tines 102 than the configuration in which the tines 102 are formed of wide plates. The colliding area is reduced and the tines 102 no longer block the discharge. As a result, even when beans having uneven dryness are threshed and the residue separated from the beans is discharged, the residue 92 does not stay in the residue discharge port 41a, and the residue can be reliably discharged. You can get the effect that you can.

In addition, in this embodiment, since a plurality of tines 102 are supported on the rotating shaft 101 so as to extend radially, compared to the case where there is only one tine 102, more residue is scraped out at a higher speed. be able to. In this embodiment, since a plurality of tines 102 are arranged at intervals in the axial direction of the rotating shaft 101, the residue 92 can be uniformly scraped out over the entire width direction of the residue discharge port 41a. , can be discharged more strongly.

According to this embodiment, the tip portion of the frame 41b contacts the tip portion of the tine 102 at a predetermined rotation angle due to the rotation of the rotating shaft 101, and the contact is released by further rotation of the rotating shaft 101. configure. The tines 102 are elastically deformed so that the tips of the tines 102 are tilted rearward in the rotation direction in the area above the residue discharge port 41a by contact, and the deformation is restored in the opposing area by releasing the contact. have. Therefore, the tines 102 are temporarily accelerated by the restoring force when the deformation of the tines 102 is restored, and the residue 92 near the residue discharge port 41a in the opposing area can be vigorously flipped off in the discharge direction.

In particular, in this embodiment, as shown in FIG. 10(b), the tines 102 are made of an elastic member that elastically deforms so as to bend, so that the residue 92 near the residue discharge port 41a is directed toward the discharge direction. , and the residue 92 can be reliably discharged from the vicinity of the residue discharge port 41a.

As a result, even when threshing beans with uneven drying conditions and discharging the residue separated from the beans, the residue can be reliably discharged without remaining in the residue discharge port 41a. effect is obtained.

In the residue discharge mechanism 100 according to the embodiment, the case where each tine 102 is made of an elastic member has been described, but the tines 102 may be made of other members. For example, the residue discharge mechanisms 100A, 100B, 100C, and 100D according to Modifications 1, 2, 3, and 4 may be used. Each modification will be described below with reference to the drawings. In addition, the same code|symbol is used for the structure similar to the residue discharge mechanism 100 which concerns on embodiment, and detailed description is abbreviate|omitted.

(Modification 1)
11, the residue discharge mechanism 100A according to Modification 1 has rotating bodies 100Aa, 100Ab, 100Ac, 100Ad, and 100Ae that are rotated by the rotation of the rotating shaft 101, as shown in FIG. Rotating bodies 100Aa, 100Ab, 100Ac, 100Ad, and 100Ae are arranged at intervals in the axial direction of rotating shaft 101 so that respective tines 102A, which will be described later, are at the same phase position. The residue discharge mechanism 100A has a function of forcibly discharging the residue 92 rearward from the residue discharge port 41a by rotating the rotary bodies 100Aa to 100Ae in the direction of scraping the residue 92 from the residue discharge port 41a. Note that the number of rotating bodies may be other than five.

The rotating body 100Aa has a plurality of tines 102A, a fixing member 103A, a fastening member 104A, and stoppers 105 and 106, as shown in FIGS. Rotating bodies 100Ab, 100Ac, 100Ad, and 100Ae are configured similarly to rotating body 100Aa.

As shown in FIG. 12, each tine 102A includes a linear rod-shaped portion 111 having a circular cross section and having relatively high rigidity, a mounting portion 112 formed at the base end portion, and a portion near the mounting portion 112. and a spring portion 113. Each tine 102A is rotatably supported on the fixed member 103A by a fastening member 104A at a mounting portion 112 provided at a position radially separated from the center of the fixed member 103A, that is, at an offset position. . By offsetting the mounting portion 112, the space for fastening the four tines 102A to the fixed member 103A is relatively widened, increasing the degree of freedom in fastening. The four tines 102A are arranged at regular angular intervals.

Each tine 102A is rotatably supported within the movable range of the angle θa between the stopper 105 and the stopper 106 . Rotation of the tines 102A with respect to the fixed member 103A of the rotating body 100Aa does not interfere with the discharge of the residue 92 flying behind the tines 102A, and the residue 92 does not stay near the residue discharge port 41a. . The tip portion of the tine 102A abuts on the frame 41b, and the spring portion 113 is deformed by further rotation. The angle with respect to member 103A changes. The spring portion 113 is formed of a coil spring elastically deformed between the distal end portion and the proximal end portion of the tine 102A so that the distal end portion of the tine 102A is bent rearward in the rotational direction. Note that the tine 102A according to Modification 1 corresponds to the residue scraping member of the residue discharge mechanism of the beans threshing machine of the present invention.

As with the fixing member 103 of the embodiment, the fixing member 103A is formed in a disc shape, and is fixed to the rotating shaft 101 by inserting the rotating shaft 101 into a through hole (not shown) formed in the center. Rotate. A plurality of fastening holes are formed in the vicinity of the outer peripheral edge of the fixing member 103A, and a fastening member 104A for attaching the tines 102 is inserted into each fastening hole. The fixing member 103A has eight mounting holes (not shown) formed near the outer periphery thereof, and stoppers 105 and 106 are mounted in the respective mounting holes.

Next, operation of the residue discharging mechanism 100A will be described with reference to FIGS. 13(a), 13(b) and 13(c).
As shown in FIG. 13(a), the residue discharge mechanism 100A rotates in the direction of the arrow, and the tips of the tines 102A rotate to move the frame 41b provided in the pod threshing housing 41 of the beans threshing machine 1. When the tine 102A abuts on the tip portion and further rotates, as shown in FIG. The angle with respect to member 103A changes. Here, the spring portion 113 is elastically deformed so that the tip portion of the tine 102A is bent rearward in the rotational direction.

When the tine 102A rotates further downward with the changed angle, as shown in FIG. The angle of the rod-like portion 111 returns to its original shape. Further, it is possible to continuously rotate the fastening member 104A to the front side in the rotational direction by the movable range θa. Therefore, the restoring force of the spring portion 113 can be transmitted to the residue over the movable range θa, and the residue 92 near the residue discharge port 41a can be flipped off with a stronger force.

A residue discharging mechanism 100A according to Modification 1 has a plurality of rotating bodies 100Aa, 100Ab, 100Ac, 100Ad, and 100Ae, and each rotating body includes a rotating shaft 101, a plurality of tines 102A, and a fixing member 103A. , a fastening member 104A and stoppers 105 and 106. As shown in FIG. The rotating bodies are arranged at intervals in the axial direction of the rotating shaft 101 so that the tines 102A are at the same phase position.

With this configuration, the residue 92 to be discharged from the residue discharge port 41a is forcibly scraped out from the residue discharge port 41a by the rotation and restoring force of the four tines 102A in the residue discharge direction.

In addition, since each tine 102A has a bar-shaped portion 111, the residue 92 to be discharged from the residue discharge port 41a collides with the tine 102A, compared to the structure in which the tine is formed of a wide plate. The area to be covered is reduced, and the discharge is not hindered by the tines 102A. As a result, even when threshing beans with uneven dryness and discharging the residue separated from the beans, the residue can be reliably discharged without remaining in the residue discharge port. is obtained.

In addition, since the base end portions of the tines 102A are pivotally supported by the fixed member 103A, the tip portions of the tines 102A can rotate along the rotation direction of the rotating shaft 101. As shown in FIG. Therefore, for example, when the residue moves from the rear side in the rotation direction of the tines 102A due to the wind from the wind force sorting mechanism 44 and collides with the tines 102A, the tines 102A can be rotated forward in the rotation direction, and the residue can be removed. It is possible to eject smoothly without stopping momentum of movement in the ejection direction.

(Modification 2)
The residue discharge mechanism 100B according to Modification 2 has rotating bodies 100Ba, 100Bb, 100Bc, 100Bd, and 100Be that are rotated by the rotation of the rotating shaft 101, as shown in FIG. The rotating bodies 100Ba, 100Bb, 100Bc, 100Bd, and 100Be are spaced apart in the axial direction of the rotating shaft 101 so that each tine 102B, which will be described later, is at the same phase position as each rotating body in the embodiment. are placed.

Note that the number of rotating bodies may be other than five.

As shown in FIGS. 14 and 15, the rotating body 100Ba has a plurality of tines 102B, fixing members 103B, and fastening members 104B.

Each tine 102B is made of a rod-shaped elastic member having a circular cross section, similarly to the tine 102 of the embodiment, and the proximal end portions thereof are fixed at positions facing each other near the center of the fixing member 103B. Each tine 102B is fastened to the fixed member 103B by two fastening members 104B so that the axes intersect at the center of the fixed member 103B. The four tines 102B are arranged at regular angular intervals. Examples of elastic members include glass fiber poles and metal rods.

As with the tines 102 of the above-described embodiment, each tine 102B is elastically deformed by the rotation of the rotating shaft 101, causing the tip portion of the tine 102B to interfere with the tip portion of the frame 41b of the bean threshing machine 1, and further rotate. , the tip portion of the frame 41b is passed through and restored to its original shape. In addition, the tine 102B according to Modification 2 corresponds to the residue scraping member of the residue discharge mechanism of the beans threshing machine of the present invention.

When the tine 102B comes into contact with the tip portion and rotates further, the tine 102B curves so as to protrude downward, as shown in FIG. 16(b).

When the tines 102B rotate further downward in the curved state, the rotation of the tines 102B is temporarily accelerated due to the restoring force of the tines 102B when they are restored, as shown in FIG. Nearby residues 92 are flipped off toward the rear of the beans threshing machine 1.例文帳に追加Subsequently, the tine 102B is restored to the original position shown in FIG. 16(a), and rotates to continuously move the residue 92 rearward as shown in FIGS. 16(b) and 16(c). and shoot it away.

A residue discharge mechanism 100B according to Modification 2 has rotating bodies 100Ba, 100Bb, 100Bc, 100Bd, and 100Be. Each rotating body has a rotating shaft 101, four tines 102B, a fixing member 103B, and a fastening member 104B. The rotating bodies are arranged at intervals in the axial direction of the rotating shaft 101 so that the tines 102B are at the same phase position. With this configuration, the residue to be discharged from the residue discharge port 41a is forcibly scraped out from the residue discharge port 41a by the rotation and restoring force of the four tines 102B in the residue discharge direction. In addition, since each tine 102B is formed of a rod-shaped member, the residue 92 to be discharged from the residue discharge port 41a collides with the tines 102B compared to the configuration in which the tines are formed of wide plates. The area to be covered is reduced, and the discharge is not hindered by the tines 102B. As a result, even when beans with uneven dryness are threshed and the residue separated from the beans is discharged, the residue 92 does not stay in the residue discharge port 41a, and the residue can be reliably discharged. effect is obtained.
