Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a threshing device, and can be used especially for eliminating stray particles discharged from the culm side of a handling room as well as sticky particles that are carried out of the machine.

[0002]

[Prior Art]

 In recent years, combine harvesters have been required to have a short threshing unit to reduce the weight and size, and in terms of performance, high-speed mowing and high-moisture threshing are required. By providing a processing cylinder and adding a processing function to share the threshing process, overall performance is improved and power consumption is reduced, but in the handling room, only a short handling cylinder is used. Since the volume of space formed between the peripheral surface and the net is small, and the density of the grain is high throughout the handling room, the straw discharged from the handling room becomes stuck and is ejected outside the machine, resulting in No. 4 loss. There is a drawback. Especially in the under-type feeder, the grains that migrate to the inner wall of the handling room may be ejected out of the machine due to irregular reflection due to the centrifugal force due to the rotation of the handling teeth, or may be thrown out by riding on the field chain. Riding the feeder chain and the pinch rail holding part as stuck particles, it will be the 4th loss.

[0003]

[Problems to be solved by the device]

 The present invention was particularly devised in order to eliminate the so-called No. 4 loss which is discharged from the exhaust side of the handling room to the outside of the machine as described in the preceding paragraph.

[0004]

[Means for Solving the Problems]

 Therefore, in order to provide a threshing device capable of eliminating this No. 4 loss, the present invention extends the feed chain extending along the mouth of the handling room from the grain culm supply side to the culm side. Is defined as a first feed chain, and a second feed chain for transferring and receiving the sandwiched grain culms is continuously provided by arranging the start end portion outside the end portion of the first feed chain. The handle teeth to be planted in the peripheral surface of the handle body facing the two feed chains are made higher than the handle teeth of other parts, and are formed inside the second feed chain at the rear side of the first feed chain terminal end portion. It was designed so that it would enter the space that would be called.

[0005]

[Action]

 With this configuration, the grain culms laterally fed from the grain culm supply side to the culm side of the handling room are first conveyed by being sandwiched and conveyed by the first feed chain, and the rotation of the handling cylinder causes the grain handling action of the handling teeth. It is received and processed, and then transferred from the end portion of the first feed chain to the start portion of the second feed chain and conveyed. And the grain culm inherited from the first feed chain to the second feed chain has a large space volume between the peripheral surface of the cylinder and the net due to the high teeth of the teeth planted on the peripheral surface of the cylinder. The grain that has been threshed on the culm side so as to be combed from the stocker side in a state where the grain density is low, and the grain that has been on the first feed chain and on the pinch rail holding part is It is dropped into the space from the end and collected.

[0006]

【Example】

 The threshing device according to the present invention will be described below with reference to an embodiment diagram. This threshing device is installed as a combine. In FIG. 1 and FIG. 2, the left side is the front side with respect to the traveling direction and the mowing grain is The culms are inherited by the feed chain, sandwiched and laterally fed, and threshed in the handling room.

That is, (1) is a handling room having a handling barrel (4) built therein, which is configured as a lower handling type by rotating the handling barrel (4) in the direction of arrow (a), and (8) is a handling chamber. Leakage from the catching net (10) of the handling chamber (1) and the discharge of the handling chamber (1) by extending from below (1) into the rear dust collection chamber (9) and swinging in the front-back direction. An oscillating sorter that sorts out what is discharged and dropped from the culm outlet (11) that opens to the culm side and what is leaked from the inside of the processing chamber (12) described below. A Glen pan (13) and a Glen sieve (14) are installed from the starting end side, a chaff sieve (15) is arranged above this Glen sieve (14), and above the chaff sieve (15). A short-length strok rack (16) is provided below the culm outlet part (5), and these strok racks (16) integrally swing.

Reference numeral (17) is a cross flow fan provided below the Glen pan (13) for raising the selection wind. The cross flow fan (17) blows down the swinging selection body (8). A sorting air duct (18) that blows from the side is formed, and (19) and (20) are the 1st and 2nd troughs installed horizontally with a screw conveyor inside, and (21) is the dust chamber. It is a suction dust collecting fan provided on the side of the feed chain (3) which is stretched above the handle (2) above (9).

The treatment chamber (12) is provided on the opposite side of the feed chain (3) from the culm side of the handling chamber (1) to one side of the shaking sorting body (8) in the front and rear direction to remove dust. Since it extends to the side of the chamber (9) and is juxtaposed with the handling chamber (1), a processing cylinder is built in the processing chamber (12) rotatably in the arrow (B) direction. The front end portion thereof communicates with the handling chamber (1) through the dust delivery port (22), and the rear end portion thereof communicates with the dust discharge chamber (9). Further, the end side of the second gutter (20) communicates with the swing selecting body (8) by a thrower (23).

Next, the above-mentioned feed chain (3) is the first feed chain (3a) from the grain culm supply side to the culm side, and the second feed chain (3b) after the culm side. ), The start end of the second feed chain (3b) is positioned outside the end of the first feed chain (3a), and the two feed chains are continuously connected so that the sandwiched grain culms are inherited and conveyed backward. In addition, the handle tooth (5) to be planted on the culm side peripheral surface portion of the handle body (4) facing the second feed chain (3b) is the handle tooth (5) implanted to the other peripheral surface portion ( 6) It is formed with higher teeth than that of 6) and enters the space (7) formed inside the second feed chain (3b) behind the terminal end of the first feed chain (3a). I have it. The first feed chain (3a) has a wider width (W) to increase the gripping power of the grain culm, and the second feed chain (3b) has a smaller width (w) to project outward. The rotation speed of the second feed chain (3b) is made faster than the rotation speed of the first feed chain (3a) so that the grain culm layer becomes thin due to the difference in speed of the inherited portion. In (10), a step (H) is formed at the boundary (24) between the portion corresponding to the high treatment tooth (5) and the portion corresponding to the other treatment tooth (6).

[0012] Further, (24) is a straw chain that carries threshing-completed straw that has been transferred laterally through the handling room (1) by the feed chain (3) and carries it out to the rear by inheriting the threshing side. A winding transmission device that extends obliquely rearward so as to be carried out to the opposite side of the feed chain (3), and is orthogonal to the axis of the handling cylinder (4) outside the outlet (11) of the culm. Power is transmitted from the shaft of the handling cylinder (4) by the gearbox (26) interposed between the gear (25) and the transmission tool (25) and the start end of the straw chain (24). The starting end of the chain (24) approaches the inner side of the second feed chain (3b) and is located on the rearward extension of the first feed chain (3a).

As a result, the cutting culms are fed laterally through the handling chamber (1) by the feed chain (3) so that the crushed grain and the threshed straw are discharged from the culm outlet (11). Throwing sorting is performed on the straw chain (24) and carried out to the rear of the machine, and the grains removed from the net (10) of the handling room (1) and those falling from the culm outlet (11) are shaken. Sorted by the swinging motion of the body (8) and the wind blown by the cross flow fan (17) and passing through the sorting air duct (18), the first product is taken out after gathering in the first product gutter (19). Then, the No. 2 product is sent to the terminal side in the No. 2 product gutter (20) and returned to the starting end side of the rocking sorter (8) by the thrower (23) for re-sorting, and the handling room (1). What is discharged from the dust outlet (22) opening to the culm side of the is processed while being sent backward in the processing chamber (12). Those that leak from the chamber (12) fall to the end side of the swing sorting body (8) and are sorted, and those that reach the rear end are discharged into the dust chamber (9) and sucked dust. Dust is discharged to the outside of the machine by the suction force of the fan (21).

Then, the grain culm laterally fed in the treatment chamber (1) by the feed chain (3) is sandwiched and conveyed by the first feed chain (3a) from the grain culm supply side, and the denture is disposed therebetween. (6) The grain is treated by (6), and then the second feed chain (3b) is inherited from the end portion of the first feed chain (3a) to pass through the step (H) at the boundary portion (24). The space between the shell (4) and the net (10) becomes large, and the grain density becomes low. On the culm side, the whole stalks are combed by the high teeth (5). The grain culm layer is thinned and the threshing treatment is promoted due to the difference in speed between the inherited portions of the first and second feed chains (3a) and (3b). Further, the grains that have been on the first feed chain (3a) and on the pinching rail holding part are dropped from the end part thereof to the space (7) on the rear side and collected. The straw fed further backward in the second feed chain (3b) approaches the inner portion of the chain (3b) and is located on the extension line of the first feed chain (3a). It is smoothly taken over by the starting end of 24) and carried out to the rear of the aircraft.
