Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rocking / sorting device for a threshing machine for mounting, in which shattered wholesale products and second products are diffused on a swinging / sorting body and uniformly supplied to a sorting chamber. is there.

[0002]

2. Description of the Related Art Conventionally, in an under-preparation type threshing machine for loading, a receiving net provided around the handling room is extended to the processing chamber side, and the unhandled goods are deviated to the processing cylinder side on the rocking sorter. In order to drop the grains and evenly supply this one-sided state to the continuous chaff sheaves, guide plates diagonally arranged in multiple rows were rotatably provided, and the lead angle was varied by detecting the accumulated grains with a sensor. A known technique is described in JP-A-59-63110. Further, a diffusing conveyor is installed horizontally over the entire width of the chaff sheave of the oscillating sorting body for screening, and the one in which the grains are forcibly dispersed is disclosed in Japanese Utility Model Publication No. 54-125373, and a guide plate or a conveyor is used. There are many known diffusion techniques,
The former has a narrow range of variation because it moves the grains along the lead angle, and the diffusion speed is also delayed, making it difficult to evenly disperse a large amount of sediment. It is closed by the side plate of the machine body and over-conveyed, and the accumulated layers are gathered on the lower side and the accumulated layer is generated on the opposite side. On the other hand, the solution for expanding the selection width is restricted by the increase in the width of the machine body, and problems such as foreign matter leaking earlier at low flow rate leading to poor selection occur, and this is the case for combine harvesters that are becoming more efficient. The tendency to deposit is further strengthened, and improvement of sorting performance and reduction of lost particles are desired.

[0003]

Even when the throughput is high and the efficiency is high, the compacted product improves the sorting performance by effectively forcibly distributing the unsorted foods in the sorting width to screen the chaff sieve. The purpose is to provide a threshing machine.

[0004]

SUMMARY OF THE INVENTION In the present invention, an unhandled article and a second article falling on an oscillating sorting body provided below a handling chamber merge together and are offset toward the processing cylinder side, and the same is laterally moved. It is configured such that it is forcibly dispersed by the provided diffusion conveyor and guided to the sorting section.

A feed pan is stretched on the starting end side of the rocking sorting body, and a diffusion conveyor supported by the left and right side plates of the sorting section is arranged above the feed pan, and the end portion to be conveyed is located at the processing cylinder rather than the center of the handling cylinder. It was installed on the side of the oscillating sorter to forcefully disperse the handling waste that falls toward the processing cylinder side on the side of the swinging sorter and uniformly supplies it to the continuous chaff sheaves.

A Glen guide facing the discharge side diffused by a diffusion conveyor is fixedly mounted on the feed pan, and the slanting height corresponding to the processing capacity is set to adjust the rear discharge amount and the lateral feed amount. Measures have been taken.

[0007] A means for forcibly diffusing both the unprocessed food and the combined second product is opened by opening the discharge port of the fried food container for returning the second product on the side better than the diffusion conveyor arranged on the feed pan. I took it.

A sensor was used to detect a fluctuating processing amount, and the number of rotations of the diffusion conveyor was increased or decreased via a transmission to take measures for effectively diffusing deposits such as wet materials at high efficiency.

DETAILED DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A diffusion conveyor device for evenly distributing deposits on a rocking sorter according to the present invention will be described below with reference to the drawings of an embodiment mounted on a combine. FIG. 5 shows the whole threshing machine on the right side. It is a plan view, the threshing part B is mounted on the machine base 13 provided with a pair of crawler traveling devices 12, and the reaping part A which can be raised and lowered is mounted in front to adjust the cutting height and the weeding board 15 The threshing part B is floated by the lifting and conveying device which floats the planted culm at
The feed chain 17 is stretched to the start end side, and the handling cylinder 20 mounted in the handling chamber 18 performs a grain-removing process. The grain is sieved by the chaff sheave 22 and the grain sheave 32 that swing in the front-rear direction while being sieved on the body 1, while guiding the grain to the sorting section 5 provided below and sorting in the direction of arrow a. This is a combine form in which good grains after removing dust by wind are collected by the first conveyor 37 and temporarily stored in the grain tank 23.

The conveying route of the shredded handling products will be described in the front view of the threshing section of FIG. 2 and the side view of the whole combine of FIG.
While carrying out the horizontal transfer, the shredder 20 sheds the particles, and the receiving net 2
Swing sorting device C in which the handled goods leaked from No. 1 are arranged in parallel below
On the other hand, the unprocessed material that has moved backward in the handling chamber 18 is sent to the processing drum 8 mounted in the processing chamber 25 for reprocessing, and the end is communicated with the suction fan 43. This is a processing path for discharging dust from the dust outlet 45 to the outside of the machine. In addition, the swinging sorting body 1 that sorts the handled goods by the sieve is the sorting unit 5
It is a configuration of an oscillating sorting device C which is supported by the arm 26 from the side plate 6 of FIG.

On the starting end side of such a swing selecting device C,
A non-perforated feed pan 2 is stretched, and the untreated food is once received and moved backward by the corrugated surface 28, and sieve selection is performed by the chaff sheave 22 and the Glen sieve 32 that are continuously provided. 5 is uniformly fed to the wind selection path 42 in which the fan 27 blows, and the mixed air is separated by the sorting wind blown in the direction of arrow a, and the good grain is conveyed by the first conveyor 37. This is a sorting route for temporarily storing in a grain tank 23 by a grain lifting machine that is continuously installed while collecting grains. On the other hand, the second product in which a small amount of grains dropped on the second conveyor 40 and unprocessed substances are mixed is returned to the upper side of the diffusion conveyor 3 arranged on the feed pan 2 by the fried grain cylinder 41, and discharged from the discharge port 55. The discharged second product and the unprocessed material accumulated on the side of the processing cylinder 8 of the rocking / sorting body 1 are in a reducing path, and the deposition line X, which is offset to the right, grows to a more remarkable mountain height. In order to eliminate this phenomenon, the swing sorting device C is equipped with a diffusion conveyor 3 and forcedly diffused.

FIG. 1 is a rear view of a diffusing conveyor provided on an oscillating sorting body, and its operation and structure will be explained by using a side view of a cross section of a main part of FIG. The start end side of the swing selecting body 1 is made to face below the surrounding receiving net 21.
As described above, the wholesale goods on the feed pan 2 and the fried food cylinder 41
No. 2 conveyed by is merged, once received, and then sent back by swinging the wavy surface 28 back and forth, but a large amount of grain leaks to the processing cylinder 8 side in the arrow B direction in which the handling cylinder 20 rotates. As a result, a deposition line X having a mountain height on the right side is formed. In the prior art guide plate that disperses such a phenomenon, the moving speed becomes slow with respect to the processing amount at the time of high efficiency, diffusion cannot be performed corresponding to the deposition amount, and the chaff sheave 22 that is continuously arranged moves while the deposition layer is thick. However, even if the lower layer drops, the surface layer remains and continues to the rear of the rocking sorting device C, and the amount of lost particles increases, so that a functional failure such as deceleration of the working speed occurs.

The installation of the diffusion conveyor for eliminating the height of the pile of the deposition line X is performed by the corrugated surface 28 of the feed pan 2.
Is a diffusion conveyor 3 forcibly dispersing the mountain height of the deposition line X from the right side of the rocking sorting body 1 in the direction of arrow D by a Glen guide 11 facing the discharge side 10 of the transport length L. It controls the amount of grains released backward and adjusts the lateral feed amount. The attachment is performed by welding a backing plate 31 to the back surface of the feed pan 2 and screwing the "V" -shaped Glen guide 11 so that the Glen guide 11 is inclined upward, and is interlocked with the swinging movement in the arrow T direction. Since the grains gather on the discharge side 10 and are discharged backward while repeating compression and expansion, pulsation occurs in the discharged grains, and a fixed amount overflows in the direction indicated by the arrow from the Glen guide 11, and the discharge amount and the lateral feed amount. It is a diffusion device that maintains the balance of. By keeping the end portion of the transport length L for this lateral feeding inside the center 7 of the handling cylinder and providing a non-acting air space on the small amount side of the deposition line X, the excessively transferred grains are released, The swing sorting device C is capable of forcibly performing left-right diffusion on the swing sorting body 1.

The drive structure will be described with reference to the cross-sectional front view of the threshing section shown in FIG. 2 and the rear view of the diffusion conveyor shown in FIG. 1. The V-belt 46 is wound around the pulleys that drive the sorting sections of the threshing section B, and is wound. The drive pulley 52 has a small diameter integrated with the rear pulley 47 for adjusting the hanging angle, and the split pulley structure is slidable so that proper rotation is transmitted to the conveyor shaft 51 supported by the bearing 50. Therefore, the input pulley 48 fixed to the shaft end receives the reduced speed rotation from the drive pulley 52, thereby rotating the diffusion conveyor 3 to prevent the winding of the straw rod mixed with the adjustment of the lateral feed speed in the arrow D direction. It's the speed.

A structure in which a speed change mechanism is provided in addition to such a belt input structure and changes according to the amount of processing is shown in the related diagram for changing the speed of the diffusion conveyor in FIG. A sensor 56 in which a conveyor culm is clamped by a straw guide 61 and a potentiometer 62 is connected to the vertically moving shaft end.
Is provided to detect the amount of actuation falling in the arrow direction and send it to the controller 63 to output the specified rotation to the electric motor 65 to rotate the tension pulley 66 in the arrow direction, thereby the tension force of the drive belt 67. Is changed, the drive pulley 52, in which the split pulley is pressed against the spring 68, is expanded and sandwiched, and the belt shift structure is provided to increase or decrease the rotation of the conveyor shaft 51. The position shown in the drawing shows the low-speed rotation state of the diffusion conveyor 3 in which the straw is not clamped.

FIG. 4 is a perspective view of the diffusion conveyor,
The dust inlet 33 opening to the end side of the handling chamber 18 is formed by being divided by a partition plate 36 attached to the rear of the net 21, and the untreated material and dust that have not leaked from the net 21 are indicated by arrows. It is a conveyance path that is sent out in the F direction and is inherited to the starting end side of the parallel processing cylinders 8, and the diffusion conveyor 3 is provided laterally on the feed pan 2 on the side better than the dust feed port 33. ,
The discharge side 10 is located below the delivery plate 35 via the Glen guide 11 facing the transport length L.
The portion to be discharged to the rear side is on the end side of the feed pan 2 and has a conveyor arrangement in which the amount of fallen objects is small, the accumulated layer is thin, and diffusion of discharged grains is further promoted.

[0017]

As described above, according to the present invention, the falling grain and the second grain are deposited and offset on the rocking sorting body provided below the handling chamber, and the horizontal diffusion is performed. Since it is configured to be forcibly dispersed evenly by the conveyor and supplied to the sorting section, the following effects are exhibited.

Since the diffusion conveyors supported by the left and right side plates of the sorting section are arranged on the feed pan of the swinging sorting body, and the transport length is set closer to the processing cylinder side than the center of the handling cylinder, the processing on the swinging sorting body is performed. The handling material accumulated on the body side was forcibly dispersed evenly on the feed pan, and the sorting performance was improved in order to reduce loss particles and improve performance.

A Glen guide opposite to the discharge side diffused by the diffusion conveyor is fixed on the feed pan, and an oblique height corresponding to the accumulated amount is set to adjust the backward discharge amount and the lateral feed amount. Since the diffusion is forcibly performed even under the condition of a wet material, the loss of grain is suppressed and the range of adapted crops is expanded.

Since the discharge port of the fried food container for returning the second product is opened on the side better than the diffusion conveyer arranged on the feed pan, both the handling product and the second product are forcibly dispersed at the same time. The whole amount of the product was diffused on the starting end side of the rocking sorting body, abnormal accumulation did not occur on the lower side, and the lost grain was reduced, improving the work efficiency.

The fluctuating processing amount was detected by the sensor, and the number of rotations of the diffusion conveyor was increased or decreased via the speed change device, and it was possible to effectively perform the diffusion particularly at a high flow rate or in the wet material.
