Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a threshing case composed of an upper case that rotatably supports a handling cylinder and a lower case that supports the upper case so that the upper case can be opened and closed to swing about a longitudinal axis. Regarding threshing equipment.

[0002]

2. Description of the Related Art In the threshing apparatus as described above, for example, Japanese Utility Model Publication No. 3-91735 and Japanese Utility Model Publication No. 3-1226.
As disclosed in Japanese Patent Publication No. 29, etc., by extending the right side plate of the lower case upward and pivotally connecting the upper case having a handling cylinder to the upper end thereof, It is configured so that opening and closing sliding operations can be performed around the front and rear axis. In other words, the right side plate of the lower case supports the upper case, and the right side plate of the lower case bears the load of the upper case and the handling cylinder. Therefore, conventionally, the right side plate is reinforced by increasing the plate thickness of the right side plate or by making improvements such as newly providing reinforcing ribs or reinforcing members on the right side plate.

[0003]

However, in the above-mentioned prior art, since the right side plate is reinforced by making the above-mentioned improvements, the entire threshing device is accompanied by the reinforcement of the right side plate. As a result, there have been inconveniences such as an increase in weight, a complicated structure, and an increase in manufacturing cost.

The object of the present invention is to effectively utilize what is originally provided in the threshing device, thereby increasing the weight of the threshing device as a whole, complicating the structure, and increasing the manufacturing cost. The purpose is to reinforce the right side plate without any inconvenience.

[0005]

In order to achieve the above-mentioned object, in the invention according to claim 1 of the present invention, an upper case for rotatably supporting the handling cylinder, and the upper case around the longitudinal axis. A threshing case is composed of a lower case that swingably supports opening and closing, and a right side plate of the lower case having the front-rear axial core is provided with an upper part of a vertical screw conveyor for conveying the first object in a posture inclined in the front-rear direction. Connected.

According to the first aspect of the present invention, originally, the upper part of the vertical screw conveyor for conveying the first thing, which is equipped in the threshing device, with the lower end connected to the lower part of the right side plate in the lower case. By connecting the right side plate of the lower case with the vertical screw conveyor above and below the right side plate, the right side plate has a structure in which the vertical direction is reinforced by the vertical screw conveyor. Also, since the vertical screw conveyor is tilted in the front-back direction, the vertical screw conveyor can be bridged in front of and behind the right side plate when it is connected to the right side plate at the upper part of the vertical screw conveyor. The structure is also reinforced by a vertical screw conveyor in the front-back direction. In other words, by effectively utilizing the existing vertical screw conveyor, the right side plate can be handled without increasing the thickness of the right side plate or adding a reinforcing rib or reinforcing member to the right side plate. It will be possible to reinforce it so that it can withstand bending and torsional forces due to the load of the body.

Therefore, by effectively utilizing the vertical screw conveyor that is originally equipped in the threshing device, the weight of the threshing device as a whole is increased, the structure is complicated, and the manufacturing cost is not increased. You can now reinforce the board.

According to the second aspect of the present invention,
In addition to the invention of claim 1, a second reduction screw conveyor is provided on the outer side of the vertical screw conveyor.
The vertical screw conveyor was arranged in a tilted posture in the front-rear direction intersecting with the side view.

According to the second aspect of the present invention, the lower end is originally located below the right side plate of the lower case, and
The second reduction screw conveyor equipped in the threshing device with the upper end connected to the upper side of the right side plate in the lower case is arranged in a front-back tilted posture that intersects with the vertical screw conveyor in a side view. This allows the right side plate to have the No. 2 reduction screw conveyor bridged in an inclined posture in the front-rear direction, which is the opposite direction to the vertical screw conveyor. The structure is more effectively reinforced by the screw conveyor. In other words, by effectively using the existing second reduction screw conveyor, the right side plate can be further reinforced so that it can withstand the bending force and the twisting force due to the load of the upper case and the handling cylinder.

Therefore, by effectively utilizing the second reducing screw conveyor which is originally equipped in the threshing device, the weight of the threshing device as a whole is increased, the structure is complicated, and the manufacturing cost is increased. It became possible to reinforce the right side plate more effectively without the inconvenience.

[0011] In the invention according to claim 3 of the present invention,
In addition to the invention according to claim 1, a second reduction screw conveyor is provided on the inner side of the vertical screw conveyor.
The vertical screw conveyor was arranged in a tilted posture in the front-rear direction intersecting with the side view.

According to the third aspect of the present invention, similarly to the second aspect of the present invention, since the existing second reducing screw conveyor is effectively used, the right side plate is further further increased to the upper case and the handling cylinder. It becomes possible to reinforce in a state where it can withstand bending force and torsional force due to the load of. By the way, in general, the lower side of the threshing case is equipped with a sorting device configured to be narrower than the handling cylinder mounted on the upper side thereof. It is bent so that it is located on the left and right center side of the threshing device, and a relatively large gap is formed between the lower side of the right side plate and the vertical screw conveyor (the above-mentioned conventional method). Actual Kaihei 3-1226 illustrated by technology
No. 29 publication). Therefore, in the invention according to claim 3, the second reduction screw conveyor is placed in a state in which the gap formed between the inner side of the vertical screw conveyor, in other words, the lower side of the right side plate and the vertical screw conveyor is inserted. As a result, compared with the case where the second reduction screw conveyor is arranged on the outer side of the vertical screw conveyor, it becomes possible to avoid the disadvantage that the width of the threshing device becomes large and the size becomes large. .

Therefore, there is no inconvenience that the weight of the threshing device as a whole becomes large, the structure becomes complicated, and the manufacturing cost increases, and moreover, it is more effective while avoiding the disadvantage that the threshing device becomes large in size. Now the right side plate can be reinforced.
