Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a removing device that removes and collects the stuck particles stuck in the straw discharged from the culm outlet of the handling room in a lower handling type threshing machine. The threshing straw that inherits threshed straw from the end of the feed chain that is stretched out and carries it out rearward is wrapped around the handling barrel axis provided outside the drainage outlet of the handling room. It can be used for a structure in which a straw chain is transmitted from the handle shaft by a transmission.

[0002]

[Prior Art]

 Conventionally, if the amount of threshing treatment increased with the increase in the amount of culm traversed in the handling room, the density of the grains increased, and the grain was stuck in the straw that was traversed in the handling chamber and discharged from the culm outlet. Since the so-called loose shavings increase and cause No. 4 loss, in order to prevent this, the number of beatings is increased by increasing the number of teeth to be planted on the culm side of the barrel, and the ceiling plate of the handling room is increased. Although measures such as installing a reverse lead valve to guide the grain to the grain culm supply side have been taken, the former type has a short stroke stroke while the handling chamber is filled with the processed material. The effect is not sufficient for cereals, and for the latter one, side effects such as waste of power due to poor dust transfer in the handling room occur due to retention of straw breaks due to reverse leads. Also, a star wheel-shaped rotating body is provided at the terminal end of the feed chain, but in any case, it is not satisfactory as a means for eliminating stuck particles.

[0003]

[Problems to be solved by the device]

 Therefore, in the present invention, since the conventional means for eliminating stab particles is not an appropriate measure as described above, a satisfactory means for surely removing and collecting the stab particles and not adversely affecting other aspects. It was devised for the purpose of making it compact and low-cost by utilizing the transmission path that transmits the straw chain from the handle barrel.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention handles a straw chain that receives threshed straw from the terminal end of the feed chain stretched along the handle of the handling room and carries it out to the rear. In a lower-side threshing machine configured to transmit straw Chien from the handle barrel shaft by a wrapping transmitter orthogonal to the handle barrel shaft provided on the outside of the culm outlet of the chamber, the endless belt of the wrapping transmitter is used. The protrusions are arranged at appropriate intervals on the outer peripheral portion, and the protrusions are inserted into the straw layer discharged from the culm outlet portion and scraped and separated.

[0005]

[Action]

 With this configuration, the power is transmitted from the end of the handle barrel shaft on the culm side to the straw chain by the wrapping transmission tool, and the feed chain directs the trash chamber to the culm side. The threshed slaughter that has been thrown laterally and crushed by the rotation of the handling drum is discharged from the outlet of the culm and transferred from the end of the feed chain to the root side of the stock straw, which is carried out to the rear. However, in this case, a protrusion arranged on the outer circumference of the endless belt of the power transmission device rushes into the straw layer discharged from the culm outlet and protrudes from the root side to the tip side along the culm. The scraps that are scraped away toward the straw and discharged to the outside are dropped and collected.

【Example】

 A description will be given below of a device for removing stuck particles according to the present invention in accordance with an embodiment diagram, and a thresher equipped with this device is mounted as a combine. In FIGS. 1 and 3, the left side is forward with respect to the traveling direction. The harvested grain culm is taken over by Feedochien, sandwiched and laterally fed, and threshed in the handling room.

That is, (1) is a handling room having a handling barrel (6) built therein, which is configured as a lower handling type by rotating the handling barrel (6) in the direction of the arrow (a), and (9) is a handling chamber. From the lower part of (1), it extends into the rear dust collection chamber (10) and swings in the front-rear direction and leaks from the net (11) of the handling chamber (1) and the drainage of the handling chamber (1). An oscillating sorter that sorts out what is discharged and dropped from the culm outlet (5) that opens to the culm side and what is leaked from 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 (9). 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. A suction / exhaust / dust fan provided on the side of the feed chain (3) that extends above (10) along the handle (2), and (22) is a partition plate that is fixedly installed on the net (11). is there.

The processing 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 vibrating sorting body (6) in the front and rear direction to remove dust. The chamber is extended to the side of the chamber (10) and is juxtaposed with the handling chamber (1). The processing chamber (12) has a processing cylinder built therein rotatably in the direction of arrow (b), Its front end communicates with the handling chamber (1) through the dust delivery port (23), and its rear end communicates with the dust collection chamber (10). Further, the end side of the second gutter (20) is communicated with the swing selection body (9) by a thrower (24).

[0010] Next, (4) is a straw chain in which the threshed straw that has been laterally transported through the handling room (1) by the feed chain (3) is carried over to the rear side by inheriting the threshing side. Then, it is extended obliquely rearward so as to be carried out to the opposite side of the feed chain (3), and is wound on the outside of the culling outlet part (5) so as to be orthogonal to the handling body shaft (6a). Power is transmitted from the handle shaft (6a) by the transmission tool (D) and the gear box (25) interposed between the transmission tool (D) and the start end of the straw chain (4).

The endless belt (7) of the winding transmission device (D) is brought close to the drive pulley (26) and the feed chain (3) side which are axially attached to the end of the handle barrel shaft (6a). The power transmitted to the driven pulley (27) by the endless belt (7) is passed over the mounted driven pulley (27) and a pair of bevel gears (28) built in the gear box (25). ) Is transmitted to the start end of the straw chain (4).

[0012] Then, rod-shaped projections (8) having a receding angle are integrally formed at an outer peripheral portion of the endless belt (7) and are rotated as shown in (C). The protrusion (8) on the lower side of (7) rushes into the straw layer discharged from the culm outlet part (5) from the upper side to scrape off the culm and scrape it from the root side to the tip side. Is configured.

As a result, the cut culm is fed laterally through the handling chamber (1) by the feed chain (3) so that the crushed grain and threshed straw are discharged from the culm outlet (5). The grain that has been taken over by the straw chain (4) and carried out to the rear of the fuselage, and the grain that has leaked from the net (11) in the handling room (1) and those that fall from the culm outlet (5) swing. It is sorted by the oscillating motion of the sorting body (9) and the wind blown by the cross flow fan (17) and blows through the sorting air passage (18), and the first item is taken out to the first item gutter (19) after being assembled. Then, the second product is sent to the terminal side in the second product gutter (20) and returned to the starting end side of the swing selecting body (9) by the thrower (24) for re-sorting, and the handling room (1). What is discharged from the dust outlet (23) opening to the exhaust side of the chamber is processed while being sent to the rear in the processing chamber (12). Those that leak from (12) fall to the end side of the swing sorting body (9) and are sorted, and those that reach the rear end are discharged into the dust collection chamber (10) and the suction dust collection fan (21). ), And dust is discharged to the outside of the machine.

Then, in the threshed straw layer discharged from the culm outlet part (5), a rod-shaped protrusion formed on the outer peripheral part of the endless belt (7) of the winding transmission device (D). (8) rushed in, and the rushed protrusion (8) came to scrape away from the root side toward the tip side along the culm as shown in (c). Along with the straw discharged by the chain (4), the straw that is about to be discharged outside is dropped and collected on the rocking sorting body (9).

Further, FIGS. 5 and 6 show another embodiment of the winding transmission device (D), which is a rod-shaped outer peripheral portion of the endless belt (7) formed by the belt. In place of the protrusions (8) formed at appropriate intervals, the chain (29) with the tines (29) arranged around the chain (29) used for mooring the culms was hung around. In addition, the suspended state of the chain (29) is formed into an inverted triangular shape to strongly inject the tines (30) into the straw layer.

[Effect of the device]

 As described above, the device of the present invention inherits threshed straw from the end of the feed chain (3) stretched along the handling opening (2) of the handling room (1) to the rear. The discharged straw chain (4) is carried by a wrapping transmission (D) which is orthogonal to the handle barrel shaft (6a) provided outside the drainage outlet (5) of the handle room (1). In the under-disposal type thresher configured to transmit the straw chain (4) from 6a), the projections (8) are arranged at appropriate intervals on the outer peripheral portion of the endless belt (7) of the winding transmission device (D). Since the projection (8) is inserted into the straw layer discharged from the culm outlet part (5) and scraped off, the culm outlet part is separated from the culm outlet part. Wrapped in the discharged straw layer, the protrusions arranged on the outer circumference of the endless belt of the transmission tool rushed in and directed from the root side to the tip side along the stem. Sucking particles that are separated by scraping, stabbed in straw and discharged to the outside are dropped and collected, so that the removal and collection of the cuttings can be reliably performed and there is no adverse effect on other surfaces. Moreover, by using the power transmission path that drives the straw chain from the handling body shaft, a compact and low-cost product could be provided.
