Description

The present invention relates to a peanut hulling mechanism that separates and sorts pods from peanut stumps, and more specifically, picks up peanut stumps that have been dug up and dried in the ground while running on its own, and thresh the pods. It relates to a self-propelled pick-up and dehulling machine equipped with a dehulling mechanism suitable for

Peanuts are positioned as an important rotation crop to maintain upland crops in main production areas, although the cultivation area has decreased due to the delay in mechanization. In recent years, peanut sowing machines and digging machines have been developed and spread to production areas. In domestic production areas, after drying the dug-up stocks in a row, they are collected and stacked (nio-zumi), and the stocks that have been sufficiently dried over a long period of time in this state are hand-made. I am doing the work of throwing it into a stationary dehuller. A stationary peanut dehuller is disclosed in Non-Patent Document 1, for example.

In order to save labor in the dehulling work, there is a demand for the realization of a work machine that picks up and dehulls the stumps that are arranged in a row at the drying stage in a field while being self-propelled (hereinafter referred to as a self-propelled pick-up and dehuller). . However, the self-propelled pick-up and de-pods machine has not been put into practical use in Japan.

For this reason, in domestic production areas, stationary dehulling machines are used, and the dried stocks are thrown in manually. In the hulling mechanism of the existing stationary type threshing machine, the stems and leaves that could not be completely crushed by the threshing drum gradually stay as residue in the threshing drum and receiving net, so they are discharged intermittently. Work is required. In addition, the depoding work targeting the stocks in the field drying stage arranged in a line is generally not performed due to concerns about insufficient pulverization and increased retention of the insufficiently dried stocks.

In order to realize a self-propelled pick-up and dehulling machine, it is essential to realize continuous work including the dehulling mechanism. When the pods removal mechanism of the existing stationary type pods removal machine is diverted to the pods removal mechanism of the self-propelled pick-up pods removal machine, the operation of discharging the residue (debris) remaining in the hauling cylinder and receiving net is intermittent. This will hinder continuous work.

In addition, when the stocks in the field drying stage arranged in a row are targeted, the tendency of insufficient pulverization and increase in retention of the insufficiently dried stocks becomes stronger. If the residue remains, the collection of pods becomes insufficient, and if the retention progresses further, the stocks put in will clog and the machine will stop working. In overseas production areas where self-propelled pick-up and hulling machines have been put into practical use, the stocks are generally dried sufficiently in the field drying process in which the stocks are dug up and arranged in rows, so the stocks are completely dried with a handling drum. Since it is pulverized into fine dust and discharged outside the machine, retention of residue is almost no problem.

In view of these points, the object of the present invention is to provide a peanut husk-threshing mechanism capable of preventing or suppressing the stagnation of residues in the handling cylinder and receiving net in order to realize continuous hull-threshing work. to provide.

Another object of the present invention is to provide a peanut pod threshing mechanism capable of preventing or suppressing an increase in stagnation of peanut residues in a hauling cylinder or receiving net due to insufficient pulverization of insufficiently dried plant. .

Furthermore, the object of the present invention is to continuously and efficiently perform the work of picking up and dehulling peanuts that have been dug up and dried in the ground while running on their own, without being interrupted due to residual residue retention. To provide a self-propelled pick-up depods machine capable of

The debris discharge protrusion is characterized by having an elastic member with a protruding length that is slidable along the receiving net.

In the present invention, in addition to the teeth for separating and dividing the roots, stems, leaves and pods of the peanut stock, an elastic member slidable along the receiving net is provided on the outer peripheral surface of the trough. Residue discharge projections are arranged. During the hulling work, the residue (foreign matter) gradually accumulates between the hulling cylinder and the receiving net, and at the same time, the residue is also discharged by the residue discharging protrusions that slide along the receiving net. As a result, the stagnation of the residue can be greatly reduced, the interruption of the pods removal operation for removing the stagnation can be prevented, or the number of interruptions can be greatly reduced, and the efficiency of the pods removal work can be improved. In addition, it is possible to effectively prevent or suppress an increase in the retention of residues on the handling drum and receiving net due to insufficient pulverization of insufficiently dried plant stock.

Here, as the array form of the tees and the projections for discharging residue, the tees and the projections for discharging residue are alternately arranged at predetermined angular intervals along the circumferential direction on the outer peripheral surface of the scouring drum. Arrangement form of arranging can be adopted. At least the tip side portion of the residue discharge protrusion that slides on the receiving net may be formed from an elastic member.

In addition, as the servicing teeth, the inclined end face facing forward in the rotation direction of the servicing cylinder is shaped to have a rectilinear receding angle, so that the servicing teeth themselves are entangled with the residue during the operation, resulting in the reduction of the staying residue. It is desirable to prevent the amount from becoming too large. That is, the slanted end face of the treatment tooth is slanted rearward in the direction of rotation at an angle of 25 to 35 degrees with respect to the normal line drawn at the intersection of the slanted end face and the slanted end face on the outer peripheral surface of the handling cylinder. It is desirable to In particular, an angle of 30 degrees is desirable.

Next, the present invention is a self-propelled pick-up and dehuller for picking up and dehulling peanut stocks that have been dug up and dried in the ground while being self-propelled,
a stock pick-up unit that picks up the dried peanut stocks;
a pod removal unit that separates, selects and collects pods from the peanut stock sent from the stock pick-up unit;
It has a running body on which the stock pickup part and the decapsulation part are mounted,
It is characterized by having the above-described pod removing mechanism as the pod removing unit.

The pod removal unit 4 located on the rear side of the vehicle body of the plant pick-up unit 3 includes a pod separation mechanism 43 that separates the pod 91 from the peanut plant 9, and the pod 91 separated from the plant 9 by wind power to remove impurities (peanut roots, and a pod collection mechanism 45 for collecting the selected pods 91 and collecting them in a pod collection box (not shown) through the pod collection pipe 42.

The pod separating mechanism 43 consists of a cylindrical handling drum 47 rotating around a rotation axis 46 extending horizontally in the vehicle width direction, and a receiving net 48 arranged horizontally in the vehicle width direction below the handling drum 47. It has 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.

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 orthogonal to the rotation axis 46 along between the shaving cylinder 47 and the receiving net 48, while pods are being removed from the peanut stalks 9. 91 is separated. A large number of residue discharge projections 52 are attached to the outer peripheral surface 47 a of the scraping cylinder 47 . Residue discharge projections 52 also protrude radially from the outer peripheral surface 47a, and serve to scrape out the residue (contaminants) remaining between the squeezing cylinder 47 and the receiving net 48 as the scouring cylinder 47 rotates. is.

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 scraping cylinder 47, and there is a residue discharge guide plate 48a bent obliquely downward and extending toward the rear of the vehicle body. formed. On the vehicle body rear side of the residue discharge guide plate 48a, a residue discharge rotary blade 53 extending horizontally in the vehicle width direction is arranged, and below this, the residue (debris) after the pods 91 have been separated is removed. A residue discharge guide plate 54 is arranged to guide the residue discharge port 41 a opened at the rear end of the housing 41 . The pods 91 and fine debris separated by the bristle teeth 51 fall through the catch screen 48 while being fed rearwardly between the treat cylinder 47 and the catch screen 48 . Residue that has not fallen off the receiving net 48 and has been sent out to the residue discharge guide plate 48a at the rear end is sent out by the residue discharge rotary vane 53, guided by the residue discharge guide plate 54, and then discharged rearward from the residue discharge port 41a. discharged to

FIG. 4(a) is an explanatory view showing the teeth 51 and the residue discharge projections 52 attached to the outer peripheral surface 47a of the scraping cylinder 47, and FIG. 4(b) is an explanatory view showing the teeth 51 taken out. , and FIG. 4C is an explanatory view showing the residue discharge projection 52 taken out.

In this example, on the outer peripheral surface 47a of the handling cylinder 47, the handling teeth 51 are arranged at regular angular intervals along the circumference thereof. At each angular interval, the treatment teeth 51 are arranged in a row along the direction of the axis of rotation 46 at regular intervals.

On the other hand, the residue discharging protrusions 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 thereof. In addition, at each position in the circumferential direction, the residue discharge projections 52 are arranged in a zigzag pattern with respect to the teeth 51 at intervals wider than the teeth 51 along the direction of the rotation axis 46 . .

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 In this example, it is inclined at an angle of 30 degrees.

As shown in FIG. 4(c), the residue discharging protrusion 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. It slides along the inner peripheral surface while being pressed against the surface.

As described above, in the pod threshing mechanism 4 of the present example, the residue discharge projection 52 for scraping out the residue remaining between the hulling cylinder 47 and the receiving net 48 is arranged. The dimensions are such that the tip portion of the elastic rod-like body 52b comes into contact with the receiving net 48 and forms a slightly curved state when mounted on the outer peripheral surface 47a of the rolling drum 47. As shown in FIG. Further, as the handling tooth 51, a plate-like tooth having a receding angle of 30 degrees on the front end face is used.

During the hulling operation, the residue (foreign matter) gradually stays between the hulling cylinder 47 and the receiving net 48, and at the same time, the residue is scraped out by the residue discharge projections 52. Therefore, retention of residues can be significantly reduced as compared with the conventional method. In addition, the general teeth for soybeans rise up from the outer peripheral surface of the teking cylinder at a nearly right angle, and because of the arch shape using a round bar, the teeth themselves are entangled with residue during work. This can result in a large amount of retained residue. On the other hand, the flat and linear treatment teeth 51 having a receding angle .theta. of 30 degrees can reduce the amount of entangled debris.

The present inventors conducted a test using a tester equipped with the above-described residue discharge projections 52 and flat teeth 51 with a rectilinear receding angle θ of 30 degrees. As a result, it was found that the amount of peanut stocks remaining in the aircraft was kept low relative to the amount of peanut stocks input, and that even when the moisture content of the stocks was high, it was possible to reduce the amount of residue in the aircraft by adjusting the machine operating conditions such as the handling cylinder. became.

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 impurities (roots, stems, leaves and other foreign matter) 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 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 . The swing-type sieve plate 55 includes a receiving plate portion 55a for receiving the pods 91 and contaminants that have fallen through the receiving net 48, and a sieve portion 55b formed continuously from the end of the receiving plate portion 55a on the rear side of the vehicle body. and

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.

FIG. 5 is an explanatory view showing the swinging mechanism of the swinging sieve plate 55. As shown in FIG. 5, 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 swings the swing mechanism vertically and in the feed direction with a predetermined amplitude. It has an eccentric rotating shaft 56a for rocking. 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 that 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, the upstream end 55d of the swinging sieve plate 55 swings up and down and back and forth with a large amplitude. Rocks up and down and back and forth with amplitude. It was confirmed that the pods 91 and the contaminants 92 can be sent out more efficiently than when the rocking sieve plate 55 is rocked up and down and back and forth with the same amplitude as a whole using a general rocking mechanism. .

Returning to 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. The upper end 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 contaminants 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 contaminants 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. Contaminants 92, such as roots, stems, and leaves, which have a relatively small specific gravity, are carried on the sorting airflow 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 to the rear side of the vehicle body. Ejected.

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. Fine contaminants 92 falling through the screen mesh of the sieve portion 55b are blown up by the sorting air flow, so that they do not fall into the pods horizontal feeding gutter 61 for collecting pods. The shield plate 60 sorts and separates the pods 91 from which the sieve mesh has fallen and the relatively fine contaminants 92 with high accuracy.

Next, the pod collecting mechanism 45 has 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 lateral feed gutter 61 are collected via the pod collection pipe 42 into a pod collection box (not shown) placed on the work floor plate 7 .
