Description

Multigrain Thresher {THRESHER FOR MISCELLANEOUS CEREAL}

The present invention relates to a threshing machine for threshing treatment for various grains such as sesame seeds or perilla crops, and more particularly, threshing by increasing the rate of graining of various grains such as sesame seeds or perilla seeds that have small particles and are difficult to shell out through structural improvement. The performance can be improved, and the threshing drum and the threshing net located below it have a structure that can be adjusted according to the shape and size of the grains, so that the optimal threshing performance can be exhibited by adjusting their installation conditions. It relates to a multigrain thresher.

In general, among the various types of miscellaneous grains produced in rural areas, grains with high demand, such as sesame and perilla, are still under agricultural mechanization. Among them, sesame seeds and perilla seeds are small, making threshing work difficult and difficult.

The crops such as sesame seeds and perilla seeds belong to crops with tall stems and small grains. These sesame or perilla grains are usually cut and dried for about a week, and then whole stems are put into a thresher to obtain granules.However, there are many cases of natural shelling during the drying process, which is handled by farmers. It is a crop that is very difficult to do.

As such, crops such as sesame and perilla must be mechanically threshed using a threshing machine before natural shelling occurs. In the above case, due to the influence of the less dried stems, the shelling is not well done, which causes the There was a problem that the amount generated was greatly increased.

To solve this problem, conventionally, a thresher having a structure with a double thresher spaced at the front and rear is mainly used, and when the stem is inserted, the thresher is first threshed in the front thresher and then less threshed in the rear thresher. The stem is subjected to a second threshing treatment in the form of second threshing.

However, among various grains, sesame and perilla seeds have different characteristics, as well as sesame seeds, but there are a number of varieties, and there is a problem that it is not easy to cope with the characteristics of these seeds or differences in varieties. It has structural disadvantages that are not suitable for threshing of the same crop.

In addition, conventionally, when the sesame or perilla seeds are subjected to threshing, there is a difference in the rate of graining depending on the dry state, but there is a problem in that it is not easy to cope with this, so improvement is required.

That is, in the conventional threshing machine, there is a problem of lowering the threshing efficiency due to disadvantages such as particles getting stuck in the parts of the device, as well as a problem that it is difficult to cope with various threshing environments such as a dry state during threshing.

In addition, conventionally, the first threshing bin and the second threshing bin are spaced apart from each other to sequentially perform the second threshing process. However, since the second threshing process is performed using a simple rotation method, sesame or perilla side grains are broken. There is a problem of reducing the threshing performance, such as occurrence of the phenomenon or less threshing occurs.

On the other hand, when looking at the prior art documents related to the thresher in the prior art, Korean Patent Publication No. 10-1449498 says "Spot welding a semicircular guide rail into which the threshing net is inserted opposite to both sides of the inner side plate of the inside of the body.
