[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing device in which a blade for ejecting a secondary product is provided in a path for returning a recovered secondary product to a sorting section.

[0002]

2. Description of the Related Art As a threshing device of this kind, a real Kaisho 5
As disclosed in Japanese Patent Publication No. 9-136931, a thrower blade for launching is provided at the end of the No. 2 screw installed in the No. 2 object collecting section, and the upper end of the thrower case containing the thrower blade is located above the sorting section. There is one that communicates with the second reducing port formed. In this threshing device, the No. 2 screw conveyed to the inside of the thrower case with No. 2 screw is hit by the thrower blade to make it into single grains, and is ejected upward, and is returned to the sorting unit from the No. 2 reducing port at the upper end. It was

[0003]

However, if the amount of threshed material is large, moist, or difficult to shatter, it is possible to effectively single granulate by hitting with a thrower blade. There wasn't. The present invention, in view of such circumstances, according to the conditions and types of threshing work,
The purpose is to make the second product satisfactorily and sufficiently single-grained so that it can be reduced to the sorting section.

[0004]

A threshing device according to the present invention is a threshing device in which a blade for hammering out a second product is provided in a path for returning the recovered second product to a sorting section. A slit is formed in the inner and outer penetrating state on the peripheral wall of the case that houses the blades, and a supporting portion that fixes and supports the receiving blade is provided in the case at a position apart from the slit, and the receiving blade is provided.
The slit is inserted into the slit from the outside in a state of being detachably supported by the support portion. The operation and effect of this characteristic configuration are as follows.

[0005]

[Function] In other words, when the amount of threshed material is large, it is damp, or the condition is poor such as difficult-to-shear varieties, the blade is inserted into the slit formed on the peripheral wall of the case and the blade is supported. It is fixed to the part and gives a sufficient deflocculating action and single graining action to the second material. Also, if the threshed product is likely to thresh and be damaged like soybean, and if it is a plant that cuts off the root of the plant with soil, it is possible to leave the blades out of the slit. It is used as a discharge hole for dust and dirt while the slits in the state where the receiving blade is removed are left as they are while making the grains into single grains only by the blades for punching. Furthermore, since the support portion is provided in the case in a state of fixedly supporting the receiving blade at a position distant from the outside of the slit,
This support portion doubles as a reinforcing member of the case, and since the receiving blade is held through the slit as compared with the case where the receiving blade is directly connected and fixed to the case, the supporting strength is high.

[0006]

As a result, the receiving blade is simply passed through the slit to face the inside of the case, or a simple switching operation is performed only by pulling out from the slit, depending on the amount of threshing material, the dryness and moisture, or the variety. Since the action of the receiving blade is properly given, it is possible to satisfactorily and sufficiently granulate without the risk of damaging the second product, which has a high threshing ability, and the case strength is also increased by the support portion. Be raised,
The supporting strength of the blade can be increased, and a highly durable processing structure can be obtained.
