Description

[Detailed description of the invention] (a) Industrial application field This invention is a threshing machine in which the lower part of both sides of the inlet and outlet sides of the threshing machine is positioned between the left and right crawlers provided along the outside of these both sides of the plate. This article relates to the lower structure of a small self-propelled self-escape system.

(b) Conventional technology Conventionally, self-propelled self-extracting machines with a configuration in which the lower part of the threshing machine is located between the left and right crawlers are disclosed in Japanese Utility Model Publication No. 19962-19962 and Japanese Patent Publication No. 47-51060. A harvesting machine that is not particularly provided with a frame for mounting a threshing machine has already been disclosed in Japanese Patent Application Laid-Open No. 55-54816.

However, the former of these known technologies has a structure in which a frame for mounting the threshing machine is provided and the threshing machine is installed on top of it, and therefore the height of the threshing machine body is correspondingly higher. Therefore, it is not possible to reduce the weight by saving materials, and in the latter case, the lower part of the threshing machine is located above both crawlers, so the height of the threshing machine is very large. The configuration is unsuitable for small-sized self-propelled self-escapes, as it cannot be expected to be made smaller.

(c) Problems to be solved by the invention Since the conventional configuration is not suitable for the configuration of a small self-extraction as mentioned above, the present invention solves the problem by installing two plates on both sides of the inlet and outlet sides of the threshing machine. In order to increase strength, we created a robust structure, and by directly connecting the lower parts of these side plates to the track frame on the crawler side, we reduced the amount of materials and weight while reducing the height of the aircraft as much as possible. It was devised for the purpose of providing a threshing machine with a high ground clearance at the bottom of the threshing machine body, which has excellent running performance on rough roads or wet fields, and which has a compact structure suitable for small-sized self-propelled self-elimination as a whole.

(d) Means to solve the problems Therefore, in order to achieve the above purpose, the present invention
The following measures are taken in a small self-propelled self-eliminating system in which the lower parts of both sides of the entrance and exit sides of a threshing machine are dropped between the left and right crawlers provided parallel to the outside of these both sides of the machine. It is something.

That is, each reinforcing member integrally formed by connecting the lower part of a reinforcing frame body having a U-shaped cross section welded to key points on the outer surfaces of the both side plates is attached to the lower outer surface of the both side plates over the entire length. At the same time as adhering, the reinforcing member is bent downward to extend downward, and the outer side of this extending portion is integrally fixed to the track frame supporting each of the crawlers, and the reinforcing member of the both side plates is The inner parts to which they were glued were connected by a connecting plate, and the engine was mounted on this connecting plate and built into the threshing machine.

(E) Effect According to this configuration, the lower part of the threshing machine is located between the left and right crawlers, lowering the height of the threshing machine, and the plates on both the entrance and exit sides are reinforced. While being sturdy, the reinforcing members are integrally fixed to both track frames that support each crawler, which greatly reduces the amount of materials and weight, while reducing the ground clearance of the connecting plate that makes up the bottom of the thresher. The height of the threshing machine does not interfere with running on rough roads or wet fields, and power is transmitted from the engine built into the threshing machine to each part, making it a small self-propelled self-propelled machine with a compact structure.
