Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a threshing device equipped with a swinging sorting mechanism located below a handling chamber that sorts the threshed material while swinging and transporting it.

[Conventional technology]

As shown in FIG. 6, this type of threshing device has a middle side plate 11 disposed between a left side plate 9 and a right side plate 10 of a sorting chamber 8 provided below a handling chamber 1, and a right side plate 10.
A receiving net 12 is installed between the left side plate 9 and the middle side plate 11, through which the grains from the handling chamber 1 leak, and between the left side plate 9 and the middle side plate 11, the grains are allowed to flow toward the receiving net 12 side. The entrance plate 5 was installed at an angle, and the grains falling from the receiving net 12 were transferred and sorted by the swinging sorting mechanism 3 disposed below the receiving net 12.

[The problem that the idea aims to solve]

However, if the width of the threshing device is to be reduced in order to make the threshing device configured as described above smaller for use in mountainous areas, the receiving net 1
As the width dimension of No. 2 becomes smaller, the leakage of grains becomes worse, and the problem of No. 3 scattering increases.

In addition, in the above conventional structure, the sorting device to which the processed material is supplied must transfer the processed material quickly while sorting it without stagnation of the processed material. Most of the processed material tends to be located on the side of the receiving net away from the feed chain, and leaks from that position. There was a problem in that the processing of the processed materials could not be completed in time, and if the amount of processed materials to be sorted was extremely large, the sorting process could not be carried out properly.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a threshing device that can perform the grain sorting process favorably without deteriorating its performance even when the threshing device is downsized.

[Means for solving problems]

In order to achieve the above object, the threshing device according to the present invention is a threshing device that is equipped with a swinging sorting mechanism that sorts the threshed material while swinging and transporting the threshing material below the handling chamber, and in the handling room. A leakage hole group for grain leakage is formed in the inlet plate disposed below the grain culm supply opening of the handling room, and a group of leakage holes for grain leakage is formed below the leakage hole in a state that is connected to the leakage hole opening edge. An inclined guide surface is provided below the leakage hole to supply the passing grains onto the rocking sorting mechanism, and further, the guided passing grains are aligned with the handling barrel axis in the guiding direction of the inclined guide surface. It is characterized in that it is set to face the side approaching the threshing feed chain in the intersecting direction.

The functions and effects of this characteristic configuration are as follows.

[Effect]

In other words, by supplying grains down onto the oscillating sorting mechanism through a group of leakage holes formed in the entrance plate in the handling chamber for grain leakage, the receiving net has a smaller leakage area due to the miniaturization of the device. The reduction in leakage at the inlet plate can be compensated for by the inlet plate section.

Moreover, the slanted guide surface provided below the leakage hole and connected to the leakage hole guides the passing grains in a direction approaching the threshing feed chain. The grain passing through is leaked and fed closer to the threshing feed chain than what leaks through the normal receiving net part of the swinging sorting mechanism, and the leaked material flows into the threshing screen of the swinging sorting mechanism. The ratio of the supply being biased towards the side away from the eed chain is reduced, and it is possible to suppress the deterioration of the sorting performance due to leakage supply locations being biased to the same location.

[Effect of idea]

As a result, even if the width of the receiving net is reduced in order to downsize the threshing device, the reduced size can be compensated for by grain leakage from the leakage holes in the inlet plate, resulting in a decrease in leakage performance. The threshing equipment can be made smaller without causing problems, and the leakage material leaked from the leakage hole is supplied to the swing sorting equipment near the threshing feed chain, so it is possible to reduce the size of the threshing equipment without causing problems. Since leakage materials can be made to be different from each other, it is possible to prevent leakage materials from concentrating on specific locations, so it is possible to prevent deterioration in sorting performance due to leakage materials concentrating on specific locations. I've reached it.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 4 shows a vertical side view of a harvester equipped with a threshing device A according to the present invention. In this harvester, the threshing device A is mounted on the front part of a machine stand 15 equipped with a crawler traveling device 14, and an engine 16, a control handle 17, and a powder bag filling and recovery section 18 are installed on the rear part of the machine stand 15. It is organized as follows.

The threshing device A has a sorting chamber 20 equipped with a swing sorting mechanism 3 and a winnow for generating sorting air 19 under a handling chamber 1 in which a handling barrel 13 is rotatably mounted. At the bottom of the sorting chamber 20, there is a gutter-shaped first item collection part 22 equipped with a collection conveyance screw 21;
A grain collecting section 18 is provided in which a gutter-shaped second material collecting section 24 equipped with a collected material conveying screw 23 is arranged side by side in sections with the first material collecting section 22 located on the upper side in the sorting direction. ,It is configured.

The engine 16 mounted on the machine base 15
and the karawine 19 are interlocked with the belt,
This china 19 and the recovered material conveying screw 21,
23 and the handling cylinder 13 are interlocked by a belt 26. Further, the dust blower 25 disposed at the rear of the threshing device A and the handling cylinder 13 are interlocked by a belt 26 as described below.

That is, as shown in FIG. 5, a pulley 27 connected to the dust removal blower 25 and a split pulley 28 connected to the handling cylinder 13 and having a large diameter part 28a and a small diameter part 28b are wrapped around each other by a belt 26. Tension pulleys 3 are interlocked and provided at the ends of V-shaped tension arms 29 which are swingably supported.
0 and 30 are brought into elastic contact with the outer surface and inner surface of the belt 26, respectively, by the urging force of a spring 31, and by pulling the end of the spring 31, the belt 26 is moved along the solid line in the figure. The large diameter part 28a of the split pulley 28 shown by and the small diameter part 28 shown by a broken line
The speed can be changed by switching to and winding the winding. According to this configuration, since the pair of tension pulleys 30 and 30 are configured to press two places on the belt 26, the distance traveled by each tension pulley 30 at the time of switching is reduced by one tension pulley 30. This is half compared to the case where the switching operation is performed, and therefore the operating amount of the spring 31 is halved, so a spring 31 with a large spring constant, that is, a small diameter and a small number of turns can be used.

Next, the structures of the handling room 1 and the sorting room 20 will be explained.

As shown in FIGS. 1 and 2, a grain culm supply port 4 is provided on the side of the handling room 1, and the grain culm whose stock is held by the threshing feed chain 2 is fed into the grain culm. The culm is supplied into the handling chamber 1 through the culm supply port 4, and is threshed with a handling cylinder 13 of a lower handling type. A receiving net 12 for grain leakage is provided on the lower outer periphery of the handling barrel 13.

On the opposite side, six groups of elongated grain leakage holes facing the threshing feed chain 2 side, formed by punching from the top surface of the inlet plate 5, are drilled, as shown in Fig. 3. As shown, below each grain leakage hole 6, a punched portion 32 formed by the punching process is formed so as to cover the lower side of the leakage hole 6 in a state continuous with the opening edge of the leakage hole 6. The embossing portion 32
An inclined guide surface 7 is formed on the upper surface to guide passing grains in a direction approaching the threshing feed chain 2 and feed them down onto the swing sorting mechanism 3.

The swing sorting mechanism 3 is configured to have a wide width so as to span both side plates 9 and 10 of the threshing device A.

[Another example]

The direction of inclination of the inclined guide surface 7 is preferably inclined toward the end of the conveyance of the threshing feed chain 2, but may be inclined toward the start end of conveyance. Further, the leakage hole 6 may be formed with a slit, and the inclined guide surface 7 provided below the leakage hole 6 may be formed by fixing a separate member to the lower surface of the inlet plate 5. .
