DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a threshing apparatus.

[0002]

2. Description of the Related Art Conventional threshing machines include, for example,
JP-A-5-162533, JP-A-61-12213, and Japanese Utility Model Application No. 51-29031 (Japanese Utility Model Application Laid-Open No. 52-1222).
No. 57), as disclosed in the microfilm,
There is one in which a side wall body that covers a side portion of a threshing room is configured to be tiltable and rotatable. With this configuration, when the side wall body is tilted and rotated, the side of the threshing chamber is opened, and an operator inspects the inside of the threshing device by pulling out a threshing net stretched under the threshing chamber from the opening. -Cleaning is possible.

Further, as disclosed in a microfilm of Japanese Utility Model Application No. 56-182,692 (Japanese Utility Model Application Laid-Open No. 58-85937), a part of a threshing net along the outer periphery of a threshing cylinder and a side portion of a threshing chamber are provided. There is a configuration in which a covering side wall body is integrally detachable outward. With this configuration, if the side wall body is removed, a part of the side surface of the threshing room can be opened, and the inside of the threshing room can be inspected and cleaned.

[0004]

As described above, in the threshing apparatus disclosed in the microfilm of Japanese Utility Model Application No. Sho 56-182892 (Japanese Utility Model Application Publication No. Sho 58-85937), it is necessary to remove the side wall body. Thereby, a part of the side surface of the threshing room can be opened, and the inspection and cleaning of the inside of the threshing room can be performed to some extent.

[0005] However, this threshing apparatus is a so-called top-handed threshing apparatus, in which a threshing net facing the upward rotation side of the threshing cylinder and a side wall body covering a part of the side surface of the threshing chamber are integrally formed on the outside. It is configured so that it can be removed to the side. Accordingly, during the threshing operation, the lower rotation of the threshing net, especially facing this side, is directed outward on the upward rotation side of the threshing cylinder due to grains, straw, etc., which are carried around in the threshing chamber by the drive rotation of the threshing cylinder. A force is exerted which tends to push the threshing net outwards.

For this reason, in the structure in which the side surface of the threshing chamber is fixed in a closed state, if the strength is insufficient, a gap is formed between the main body of the threshing chamber and the side wall, so that the grain Straw chips etc. leak from the threshing room to the outside. Also,
In the configuration in which the side wall body is fixed in the closed state, increasing the strength is accompanied by a complicated structure and an increase in weight, which is irrational.

[0007]

The present invention employs the following technical means in order to solve the above-mentioned problems. That is, a threshing cylinder 1 is rotatably mounted in a threshing chamber 2, a threshing net 3 is provided along the outer periphery of the threshing cylinder 1 so as to be separable in the circumferential direction, and a threshing net 3 facing the downward rotation side of the threshing cylinder 1 is provided. And a side wall body F covering a side portion of the threshing chamber 2 so as to be integrally openable to the outside.

[0008] With this configuration, the grain culm supplied to the threshing chamber 2 is subjected to threshing by a threshing cylinder 1 rotatably mounted in the threshing chamber 2 and a threshing net 3 along the outer periphery thereof. Grains, small straw chips, and the like that have leaked from the joint are taken over by a lower sorting device and sorted. Then, during the threshing operation, if a trouble such as clogging occurs in the threshing room 2 or after the operation is completed, it is necessary to inspect and clean the inside of the threshing room 2 and the like.

In such a case, if the side wall body F is opened outward, the threshing net 3 is separated in the circumferential direction and is opened outward integrally with the side wall body F. As a result, the side of the threshing cylinder 1 is opened, and inspection and cleaning such as removal of clogging at a portion where the threshing net 3 and the threshing cylinder 1 face each other can be performed. In addition, even though the side wall body F is configured to be openable in this way, when closed, the threshing net 3 integrated with the side wall body F faces the downward rotation side of the threshing cylinder 1. The force for pushing the threshing net 3 to the outside is not so much exerted by the grains, straw chips, etc., which are brought into the threshing chamber 2 by the drive rotation of the threshing.

Therefore, a gap between the main body of the threshing chamber 2 and the side wall body F, and a problem in which grains, straw chips, etc. leak out to the outside can be suppressed with a simple structure.

[0011]

As described above, according to the present invention, by opening the side wall F, the threshing net 3 is also opened to open the side of the threshing cylinder 1, and the inspection and inspection inside the threshing chamber 2 is performed.
The structure that can be cleaned was rationally realized with a simple structure.
