Description

Description: TECHNICAL FIELD The present invention relates to a threshing device, and can be used in a stationary threshing device, a combine and harvester threshing device, and the like.

[Prior art]

In the publicly known Japanese Utility Model Publication No. 58-143523, a plurality of control plates are arranged on the inner surface of the handling port side machine wall of the handling room and are tilted in a direction substantially parallel to the handling barrel axis. A technique is disclosed in which the control plate is pivotally attached to the control rod so that the inclination angle of one of those control plates located on the supply port side is successively smaller than that on the exhaust port side.

[Problems to be Solved by the Invention]

In the technique of the above publication, the control plate is gradually smaller from the outlet side to the supply side, that is, the inclination angle of the control plate near the central portion of the handling chamber is larger than that on the supply side and smaller than that on the outlet side. The configuration is small and has the following drawbacks.

Most of the threshing is usually processed in the front of the handling room,
Near the middle part of the handling room, there is little grain loss. Despite this condition, the inclination angle of the control plate is not so large, so there is almost no resistance to grain removal, so it is sent to the end of the handling room, and the inclination angle on the outlet side is reduced. It is blocked by a large control board. As a result, the threshing that has been blocked only at the end of the handling room becomes a dumpling state, and since there is no threshing means behind the end of the handling room, branch shoots and clams are difficult to thresh and sort. There are drawbacks.

[Means for Solving the Problems]

The present invention takes the following technical means in order to solve the above problems.

That is, a plurality of resistance plates 4, 4, which are arranged in the threshing chamber 2 along the axial side portions of the threshing cylinder 1 to give a resistance to the transfer of the object to be processed in the axial direction and whose tilt angles can be adjusted, ... and a plurality of resistance plates 4a, 4 on the transfer side of these resistance plates 4, 4 ,.
a, ... group and a plurality of resistance plates 4b, 4b, ... on the lower side, and an inclination adjusting means for adjusting the resistance group to a large side or a small side of the transfer resistance. Both transfer plates 4a and 4b for small adjustment of transfer resistance, which is almost orthogonal to the axial direction.
The tilt directions of the groups are almost the same, and when adjusting the transfer resistance large,
The resistance plate on the lower side has a tilt angle (b) of the 4b group on the lower side.
The threshing device is characterized in that the slant angle is adjusted to be larger than the slant angle (a) of the 4a group.

[Operation and effect of the invention]

When the threshing is threshed by the rotation of the threshing cylinder 1 in the threshing chamber 2, the grains in the threshing are leaked from the threshing chamber 2,
Straw wastes containing grains and branch adhering grains and the like are transferred to the rear side of the threshing chamber 2 and discharged to be reprocessed. Threshing tube 1
When the grain is leaked on the front side of the grain and the grain leaks, the amount of the grain in the threshing chamber 2 decreases as it is transferred to the rear side of the threshing cylinder 1, and It becomes straw scraps and branch adhering grains that contain it.

As described above, according to the present invention, among the resistance plates 4, 4, ..., A group of resistance plates 4a, 4a, ... on the transfer side and a group of resistance plates 4b, 4b, .. If you adjust to a state with less
When the inclination angles of the resistance plates 4a, 4b on the upper side and the lower side are substantially the same, and when the transfer resistance is largely adjusted, the lower side with respect to the inclination angle (a) of the resistance plates 4a, 4a on the upper side. The resistance plates 4b, 4b, ... of the slant angle (b) are adjusted to a large slant angle that gives a greater transfer resistance. The grain can be easily transferred, and the grain can be prevented from staying for a long time, and the angle of inclination in the latter half of the threshing chamber 2 becomes large, so that the feeding performance is suppressed compared to the first half, and the grain can be removed. It is possible to apply the handle action for a relatively long time while maintaining the state suitable for the handle processing capability. As a result, the threshing treatment of the straw waste containing the grains is improved, and the shoot-attached grains are satisfactorily threshed.

If there is a lot of grain removal, the resistance plates 4a, 4a, ...
Since the inclination angle of the and the resistance plates 4b, 4b, ... on the lower side are set to be substantially the same as that of less resistance to the transfer of the grain removal, the overload in the grain removal 2 And the discharge of threshing from the threshing chamber 2 can be facilitated.

Therefore, a good threshing selection process can be performed in both a large threshing state and a small threshing state.

Below the threshing chamber 2, a swing sorting device (not shown) is installed to sort threshing grains that have leaked from the receiving net 6 and the sheave 7 while being transferred. Although not shown in the drawing, a Kara-mino fan, a No. 1 trough and a No. 2 trough, which generate a selection wind from the front part, are sequentially arranged below this under the drawing.
At the front of the threshing chamber 2, a feed chain 9 is provided along the handling opening 8.
And a sandwich rod 10.

A threshing portion 13 having a large number of handling teeth 12 spirally arranged on the outer periphery is formed on the grain culm inlet 11 side portion of the threshing cylinder 1, and a screw is connected to the handling tooth 12 at the outlet 14 side portion and screwed. A screw threshing section 16 provided with 15 is formed.

On the inner surface of the cover 3 of the threshing chamber 2, a plurality of resistance plates 4, 4, ... Are arranged along the axial direction of the threshing cylinder 1, and each resistance plate 4, 4 ,.
Is arranged in a state in which the longitudinal direction of is aligned with the rotation direction of the threshing cylinder 1. The resistance plates 4, 4, ... Provide a sending resistance to the threshing threshed by the rotation of the threshing cylinder 1 in the threshing chamber 2. The resistance plates 4, 4, ...
, And a plurality of resistance plates 4b, 4b, which are provided so as to face the screw threshing section 16.
It consists of ... and.

One end of each of the resistance plates 4a, 4a, ... Is rotatably pivoted to the inner surface of the cover 3, and the intermediate portion thereof is rotatably pivoted to the connecting rod 18. Further, one ends of the resistance plates 4b, 4b, ... Are rotatably pivoted 17 to the inner surface of the cover 3, and the one ends are pivotally rotatably attached to the linking rods 20, respectively. An arm 21 is rotatably connected to 18,20. Of the resistance plates 4a, 4a, ..., the pivotal connection 17 of the resistance plate 4a on the right side 17
The base portion of the operation lever 19 is integrally provided in the section, and the resistance plates 4a, 4a, 4a, 4a,
..., 4b, 4b, ... are rotated around the pivot 17, and are rotated toward the entrance 11 side of the threshing chamber 2 in a state of large inclination with respect to the axial direction of the threshing cylinder 1 having a large resistance. It is a composition. At this time, the rotation angle (b) of the resistance plates 4b, 4b, ... on the lower side becomes a large inclination angle with respect to the rotation angle (a) of the resistance plates 4a, 4a ,. In comparison, the resistance is adjusted so that the resistance is greatly adjusted.

When the operating lever 19 is rotated clockwise, the resistance plates 4a, 4a

When the grain culm is sandwiched by the feed chain 9 and the clamping rod 10 and is transferred and supplied from the inlet 11 side, the grain culm is the threshing cylinder 1
The threshing part 13 of the tooth is threshed.
It leaks from the bottom and is sorted by the swing sorting device below. The remaining threshing is shredded by the screw threshing unit 16, and the grain leaks from the sheave 7 and is sorted by the swing sorting device. Regarding the transfer speed of the threshing threshed in the threshing cylinder 1, the screw threshing section 16 is faster than the handling tooth threshing section 13, and moreover, the threshing cylinder 1
On the lower side, there is little threshing, so there is a tendency for the threshing chamber 2 to be discharged without complete threshing.

Therefore, the operation lever 19 is rotated clockwise to adjust the resistance plates 4b, 4b, ... To the large inclination angle side, and the transfer of grain removal is suppressed. As a result, the threshing treatment of the straw waste containing the grains is improved, and the shoot-attached grains are satisfactorily threshed. This time,

When the number of grain culms thrown into the threshing chamber 2 increases, the threshing cylinder 1 becomes jammed not only in the upper direction but also in the lower direction, and an excessive load acts on the threshing cylinder 1 to rotate it. As the number decreases, so does the sorting capacity. Therefore, when a large amount of grain stalks are thrown in, the operation lever 19 is rotated counterclockwise so that the resistance plates 4a, 4a, ... And the resistance plates 4b, 4b ,.
And are rotated in a direction that does not suppress the transfer of grain removal on the small inclination angle side. That is, the state shown by the alternate long and short dash line in FIG. As a result, from the upper side to the lower side of the threshing tube 1, the threshing resistance is weakened and the threshing is smoothly transferred and discharged without being clogged.
