Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a threshing apparatus.

[0002]

2. Description of the Related Art Conventionally, a threshing apparatus is disclosed in Japanese Unexamined Patent Publication No. 7-250.
As disclosed in Japanese Patent Application Publication No. 548, a dedicated receiving network guide for supporting the receiving network is provided.

[0003]

According to the above-mentioned conventional structure, a dedicated receiving guide for supporting the receiving guide is provided, so that the number of parts and the number of manufacturing steps are increased, and
Manufacturing costs were high.

An object of the present invention is to reduce the number of parts and the number of manufacturing steps, and to reduce the manufacturing cost.

[0005]

The structure, operation and effect of the present invention are as follows.

[Structure] An arc-shaped rib extending along the lower edge of the grain stalk supply port by bulging inward the lower part of the grain stalk supply port of the front plate and the rear plate forming the handling chamber. Respectively,
The upper surfaces of both arc-shaped ribs are formed on the receiving surface of the receiving net.

[Effect] An arc-shaped rib extending along the lower edge of the cereal culm supply port by bulging the lower part of the cereal culm supply port of the front side plate and the rear side plate forming the handling chamber inward. Respectively,
Since the upper surfaces of both arc-shaped ribs are formed on the receiving surface of the receiving net,
It is not necessary to provide a dedicated receiving guide, and the strength of the front plate and the rear plate can be increased without providing a reinforcing member.

[Effect] Accordingly, the number of parts and the number of manufacturing steps can be reduced, and the manufacturing cost can be reduced.

The threshing case 19 includes an upper case 19A that rotatably supports the handling drum 10 around a front-rear axis X1.
The lower case 19B supports the receiving net 11, the swing sorting device 12, and the like. Upper case 19A
Are disposed so as to extend between the first front side plate 19a and the first rear side plate 19b disposed before and after the handling cylinder 10 and the first front side plate 19a and the first rear side plate 19b above the handling cylinder 10. The handling plate 10 is formed so as to cover the handling cylinder 10 from above by the top plate 19c. The lower case 19 </ b> B includes a second front side plate 19 d disposed in front of the swing sorting device 12 and the first rear side plate 1.
9b, a bottom plate 19e disposed below the swinging sorting device 12, and a left side plate 19f and a right side plate 19 arranged to the left and right of the swinging sorting device 12.
By g or the like, the handle cylinder 10 is formed to be covered from below and to surround the swing sorting device 12 and the like. That is, the first front side plate 19a, the top plate 19c, and the first rear side plate 19
A handling chamber 34 is formed by b, the second front side plate 19d, the second rear side plate 19h, and the like. Right side plate 19 of lower case 19B
