Ru.

0002

[Conventional technology]

Conventionally, the adjustment by the feed adjustment means, that is, the guiding angle of one dust feeding valve is By simply changing the types of rice, wheat, soybeans, millet, etc., and conditions such as moisture and volume, It was configured to display the sending according to the situation.

0003

[Problem that the idea aims to solve]

Therefore, according to the prior art, in order to accommodate a wide range of feed adjustments, it is necessary to It is necessary to widen the angle change range of the dust feeding valve. Therefore, for example, As shown in the example, the fulcrum is near the upper end of the dust sending valve in the direction of rotation of the handling cylinder. If the configuration is such that the guiding angle can be changed by rocking, Accordingly, the position of the lower end of the dust feeding valve in the direction of rotation of the handling cylinder in the rotational axis direction and circumferential direction is also determined. Other requirements also change significantly as the guiding angle changes. . And, since large fluctuations in other requirements like this affect the feed, it is difficult to use conventional technology. When determining the shape, size, installation location, etc. of the dust supply valve, take this into full consideration. This has the drawback of making design and manufacturing difficult. The purpose of the present invention is to eliminate the above-mentioned drawbacks.

0004

[Means to solve the problem]

The characteristic configuration of the whole culm input type threshing device according to the present invention is that the other of the two locations is A second feed adjustment means is provided for changing the guiding angle with respect to the circumferential direction of the dust feeding valve. Set the minimum value of the angle change range by the feed adjustment means in step 2 to a value smaller than zero, The minimum value of the angle change range by the feed adjustment means is a value greater than zero, and , the absolute value of which is set to a value greater than the absolute value of the minimum value.

[0005]

[Effect]

A second adjustment means is provided to adjust the feeding by changing the guiding angles of the two dust feeding valves. Since it is designed to be adjusted, the dust supply valve at one location can be used to transport dust from the dust supply valve at the other location. You can share the coordination. As a result, while a wide range of feed adjustments can be made, only one dust valve can be adjusted. Both the angle change range of the dust supply valve and the angle change range of the other dust feeding valve can be reduced. Ru. In addition, feed adjustment should be done at the start of work depending on the type of crop, and then Fixed type feed adjustment that fixes the condition, and adjustment at any time during work according to the ever-changing conditions. There is a feed adjustment method that is performed as needed, but in the present invention, two feed adjustment means are provided. One of the feed adjustment means is for fixed feed adjustment, and the other feed adjustment means is for fixed feed adjustment. By using it for adjusting the feed of the shape at any time, two types of feed adjustment can be performed independently. , compared to the case where two types of feed adjustments are made using one feed adjustment means, the adjustment is easier. And it can be done accurately. Moreover, the minimum value of the angle change range by the second feed adjustment means is set to be smaller than zero. value, while setting the minimum value of the angle change range by the feed adjustment means to be greater than zero. Since the induction angle of both types of dust supply valves is set to the minimum value, the By slowing down the feed in this direction, the residence time in the handling chamber becomes longer, making it difficult to form single grains. When dealing with difficult conditions, a dust valve with a positive induction angle directs the material to be processed along the axis of rotation. The dust can be sent in the opposite direction due to the dust feed valve with a negative induction angle. As a result, the processed material moves along the rotation axis and is agitated. The stirring promotes single graining and improves single graining performance. Moreover, the absolute value of the minimum value of the angle change range by the feed adjustment means is adjusted by the second feed adjustment. The induction angle of both types of dust feeding valves is larger than the absolute value of the minimum value of the angle change range by the means. Even if both degrees are set to the minimum value, the feed in the feed direction is ensured. No clogging of processed materials.

[0006]

[Effect of the idea]

Therefore, according to the present invention, the angle change range of the dust feeding valve is small and the design , manufacturing can be carried out advantageously, and processing performance can also be improved at the same time.
