[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net holding structure for a threshing machine which can increase the area of the threshed by a handling cylinder, which leaks downward.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Publication No. Sho 62-42688, a crimping mesh below a handle cylinder is provided at a lower end portion of a mesh holding plate extending from an inner side of a feed chain to a position below a handle cylinder. In a threshing machine having end portions connected continuously, a technique is known in which a crimping net is further stretched on the mesh holding plate.

[0003]

In the above prior art, there is a problem that the crimping net is stretched on the net holding plate in the vicinity of the handling port, so that the threshing action is reduced and the unhandled portion is left. . In addition, if the crimping net is stretched small to prevent this, collection of stinging particles in the vicinity of the exit cannot be performed sufficiently, and stinging particles at the base of the culm are taken out of the machine. .

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem, and the present invention is applied to a lower end portion 3a of a mesh holding plate 3 extending from the inside of the feed chain 1 to a position near the lower portion of the handling cylinder 2. In the threshing section which is formed by continuously connecting the end portions of the crimping net 4 below the mesh holding plate 3, the opening 5
The crimping net 6 is stretched over the entire surface of the opening 5 and the crimping net 6 is vertically
Direction length H2 is longer than the vertical length H1 on the handle side.
It is configured to be wider as it goes to the exit side .

FIG. 1 is a cross-sectional view of a part of a threshing machine mounted on a combine. A clamping culm 8 having an outlet side higher than an entrance side and a feed chain are provided outside a handling room 7 in which a handling cylinder 2 is provided. 1
Are installed vertically, and the cylinder 2
An end of a crimping net 4 stretched from the lower side of the handling cylinder 2 to the rear is connected to a lower end portion 3a of the mesh holding plate 3 extending to near the lower side of the mesh holding plate 3 through a mounting bracket 9, and A swing sorter 12 below the handling cylinder 2 is installed below the falling plate 10 inclined below and below the falling plate 11 inclined below the rear side of the handling chamber 7. It is configured in the same manner as the shape structure, but as shown in FIG.
a approaches the lower end 3a of the net retainer 3 and the width L
A large opening 5 is formed which is longer along the length of the opening 5 and has a shorter longitudinal length H ₁ on the inlet side and a longer longitudinal length H ₂ on the outlet side, and a crimping net 6 is stretched over the entire surface of the opening 5. At the same time, the periphery of the crimping net 6 is attached by an attachment 13. In addition, it is also possible to provide a structure in which a horizontal or vertical ridge for reinforcement is interposed in the opening 5.

Accordingly, it is possible to increase the leak area below the handling cylinder 2 by the area of the crimping net 6 stretched in the opening 5 of the mesh holding plate 3, and to rotate the handle as shown by the arrow a. The processing capacity of the threshed material threshed by the body 2 can be increased, and the threshed material leaking from the crimping net 6 of the net holding plate 3 is reduced by the falling plate 10.
The crimping net 4 and the falling plate 11 fall on the rocking sorter 12 from above.
The rocking sorting is effectively performed while being dispersed moderately over the entire surface in combination with the threshed material falling from the stalk, and the stabbing particles falling from the culm base side of the grain culm are removed from the crimp net 6 of the mesh holding plate 3. by leakage Do will be possible to prevent the taking out, the longer the longitudinal length H ₂ of the outlet as in example, since挾扼site culms increases at the outlet side, the sticks grains fall and Moshita It can be performed more effectively.

[0007]

[Effects of the Invention] As described above, the present invention provides a net holding plate 3
The leakage area below the handling cylinder 2 can be increased by the area of the crimping net 6 stretched in the opening 5 of the above, and the processing capacity of threshed material threshed by the handling cylinder 2 can be further improved. The threshed material leaking from the crimping net 6 of the mesh holding plate 3 can be dropped to the side of the lower rocking plate, and the threshed material is entirely spread on the rocking plate. Efficient swing sorting can be performed while dispersing moderately. In addition, in the present invention, in particular, the length of the clip net 6 stretched on the net holding plate 3 is set such that the vertical length H2 on the outlet side is longer than the vertical length H1 on the handle side, and the length increases toward the outlet side. Since it is configured as much as possible, threshing action near the handling mouth can be kept strong, unretained handling can be reduced, and at the exit side, the crimping net works up to the upper side, so stabbing grains falling from the stem side of the grain culm Can be sufficiently recovered, and a highly accurate threshing operation with little loss is possible.
