Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a threshing machine mounted on a combine harvester, etc., and the present invention uses a main oscillator that performs an agitating motion to prevent clogging of a handling net stretched over the lower part of the handling barrel of the threshing machine. This invention relates to a device for preventing clogging of a handling net in a thresher, which is prevented by a brush provided on a dynamic transfer sorting plate.

[Prior art]

When using a combine harvester that threshes grain while harvesting the erect grain culms in the field, not only the erect grain culms with a normal moisture content, but also the erect grain culms that are still wet with morning dew, or those that have fallen down in the muddy soil of wet rice fields and have muddy soil attached to the ears. The current situation is that it is desired to reap and thresh even the standing hair culms.

By the way, when a threshing machine is used to thresh a standing grain culm that is still wet with morning dew, or a standing grain culm that is covered with mud all the way to the ear tip, the damp grain is deposited at the bottom of the handling net where the handling teeth do not work. The culm is attached,
As a result, the amount of grains that leak through the mesh of the handling net and fall downwards is small, but the amount of grains that leak through the mesh of the handling net and fall downward becomes small. However, there is a problem that the applicability of reaping and threshing under these conditions is narrow because the amount of grain that is mixed with the scraps and discharged outside the machine increases, resulting in an increase in lost grains.

[Purpose of invention]

The present invention was devised to solve the problems in view of the above-mentioned conventional situation, and utilizes the longitudinal and vertical vibration movement of the seed oscillating transfer and sorting plate installed below the handling net. An object of the present invention is to provide a device for preventing clogging of a handling net in a threshing machine, which can prevent clogging of the handling net using a brush for cleaning the handling net attached to a seed oscillating transfer sorting plate.

A sub-selection air passage 18 is formed that blows through a chaff sheave 20 provided on the rear side of the sub-oscillating transfer and selection plate 21 which is disposed downwardly and inclined upward.

In addition, on one side of the machine, there is a first grain lifting cylinder (not shown) for taking out the sorted grains outside the machine, and a second grain lifting cylinder (not shown) for removing the sorted grains from the machine, and a second part on the main swinging transfer sorting plate 15 below the handling net 4. A second product reducing thrower 22 for reducing the grain to is connected to the transfer end of the second product reduction spiral 17, and the end of the second product reduction thrower cylinder 23 extends forward and upward, passes through the side of the handling barrel chamber 5, and faces onto the main swing transfer transfer sorting plate 15. be.

As shown in FIG. 2, a handling port 47 communicating with the handling barrel chamber 5 is opened along the axial direction of the handling barrel shaft 6 on the other side of the fuselage, and a feed chain 24 is wound around the outside of this handling port 47. At the same time, a pinch rail 25 is arranged opposite to the conveying surface of the feed chain 24, and the harvested grain culm fed to the starting end side is placed between the feed chain 24 and the pinch rail 25. While being held between the husks and being transferred through the handling port 47 toward the terminal end, the tip side is threshed in the handling barrel chamber 5, and the discharged culm after threshing is transferred to the terminal end side of the feed chain 24. It is transferred to the starting end side of the disposed culm discharge chain 26 and transported outside the machine.

In addition, a handling trunk chamber 5 is provided below the feed chain 24.
A processing barrel chamber 50 is provided which communicates with the processing barrel chamber 50, and a processing barrel shaft 51 extending in an axial direction parallel to the axial direction of the processing barrel shaft 6 is rotatably supported within the processing barrel chamber 50.

Behind the grain flow plate 30 of the main oscillating transfer sorting plate 15 is a main oscillating transfer sorting plate 15 extending rearward with an upward slope.
A sub-oscillating transfer and sorting plate 21 is provided which swings integrally with the transfer protrusion 19.
and a chaff sheave 20 continuous to the rear of the transfer projection 19.

In addition, as shown in another example in FIG.
A predetermined number of fluffs 48 are formed between the handling teeth 2 and are formed to a predetermined width, and the fluffs 48 are attached to the handling barrel 3 so that the tips 49 of the fluffs come into pressure sliding contact with the inside of the handling net 4 due to the restoring force of the brush material. By rotating the grains together with the handling drum 3 with the grain facing backward in the rotational direction, grains floating in the handling drum chamber 5 can be leaked from the handling net 4, and clogging of the handling net 4 can be prevented. I'm starting to be able to do that.

In the present invention, a brush 40 for cleaning the net 4, which faces around the net 4 from below, is provided on the upper surface of the swing transfer sorting plate 15 in a direction perpendicular to the axial direction of the handling barrel shaft 6, and The clogging of the handling net 4 is removed by a brush 40 that swings together with the dynamic transfer and sorting plate 15.

That is, as shown in FIGS. 1 and 2, a pair of left and right mounting brackets 36 extending in the vertical direction are attached to the flat surface 2 of the main swing transfer sorting plate 15 located below the handling net 4.
9, and the mounting brackets 3 consisting of a pair of left and right
6, 36, both ends of a mounting bracket 37, which is disposed in a direction perpendicular to the axial direction of the handling barrel shaft 6, are freely fixed with bolts, nuts, etc. As shown in FIG. 3, this mounting bracket 37 has a brush 40 for cleaning nets, the base of which is fixed in such a manner that the brush material bypasses the round bar 39 by the mounting bracket 37. 40 has its end face 38 facing the periphery of the handling net 4 from below, and in the embodiment, the end face 38 is formed in an arc shape along the periphery of the handling net 4 in contrast to the linear mounting bracket 37. The mounting bracket 37 is formed in an arc shape along the periphery of the handling net 4 so that the brush bristles become the same length, although the brush bristles gradually become longer as they move upward. You can.

By arranging a plurality of brushes 40 for cleaning the handling net at appropriate intervals in a direction perpendicular to the axial direction of the handling barrel shaft 6, clogging can be removed over the entire length of the handling net 4. It has become like this,
At this time, in a threshing machine in which an auxiliary oscillating transfer sorting plate 32 is arranged above the main oscillating transfer sorting plate 15, an auxiliary oscillator facing below the handling net 4 is used as shown in FIG. A brush 4 is placed on the top surface of the dynamic transfer sorting plate 32.
0 may be attached.

Further, cleaning openings 43 and 4 are provided in the side walls 41 and 42 located on both the left and right sides of the main swinging transfer sorting plate 15.
4 are opened respectively, and these cleaning ports 43,
44 is provided with open/close lids 45 and 46 that can be opened and closed freely, and a brush 40 can be attached and detached together with the mounting bracket 37 through these cleaning openings 43 and 44.
The brush 40 can be cleaned and worn brushes 40 can be replaced.

In this way, by stirring the brush 40 whose end surface 38 faces the periphery of the handling net 4 from below together with the main swinging transfer and sorting plate 15 back and forth and up and down, the end surface 38 of the brush 40 is moved into the mesh of the handling net 4. The handling net 4 can be moved into sliding contact with the lower part of the handling net 4, thereby allowing the handling net 4 to be moved into contact with the handling teeth 2.
Wet grain culm leaves, mud, etc. that are attached to or hanging down and are blocking the net from below the handling net 4 are removed every time the main oscillating transfer sorting plate 15 is oscillated. Therefore, clogging of the handling net 4 can be prevented.

Therefore, by preventing clogging of the handling net 4, even when standing culms are wet with morning dew or when mud is still attached to the tips of the culms,
This can be threshed, expanding the scope of application of threshing.

In addition, mounting brackets 36, 36 consisting of a pair of left and right
The main swinging transfer sorting plate 15 is constructed of an elastic member such as a plate spring made of spring steel.
The combination of the inertia caused by the swinging of the brush 40 and the sliding resistance of the brush 40 itself as it slides into contact with the lower part of the handling net 4 makes it possible to slightly vibrate the mounting brackets 36, 36 made of elastic members. Moist leaves and mud adhering to the net can be sieved off, and the prevention of clogging of the handling net 4 by the brush 40 can be maintained for a long period of time.

[Effect of idea]

As described above, the present invention provides a main oscillator that vibrates below the handling net stretched below the handling cylinder of the threshing machine in the longitudinal direction and the vertical direction of the handling cylinder, which is the axial direction of the handling cylinder. A dynamic transfer sorting plate is disposed, and a brush for cleaning the handling net is provided on the main swinging transfer sorting plate, facing the handling net from the lower side thereof and arranged in a direction intersecting the axial direction of the handling cylinder. Once installed, the handling barrel cleaning brush not only slides along the underside of the handling net as the main oscillating transfer sorting plate vibrates back and forth and in the vertical direction, but also its tip penetrates through the opening of the handling net. I come to do it.

As a result, it has become possible to more forcefully and reliably remove wet grain culm leaves, mud, etc. that block the opening of the handling net.

Furthermore, the present invention utilizes the swing motion of the main swing transfer and sorting plate as the swing source for the net cleaning brush, so there is an advantage that a dedicated drive device is not required.

Therefore, by preventing clogging of the handling net, it is possible to thresh even standing grain culms that are wet with morning dew or that have mud attached to the tip. It is possible to expand the applicable range of threshing in combine harvesters.
