[0002]

2. Description of the Related Art Conventionally, in this type of Glen tank structure, the member constituting the adjusting means is an L-shaped plate-like member in the shape of an upward concavity when viewed from the screw axial direction of the screw conveyor. The adjusting plate is provided so as to receive the load of the grain so that the load of the grain is not directly applied to the screw conveyor. Then, in order to change the width of the gap between the adjusting plate and the wall plate of the Glentank, means for making the adjusting plate displaceable up and down, a mountain-shaped fixing plate for receiving the load of the grain, and the fixing plate. Two means have been proposed: a movable plate that slides up and down in an overlapping manner, and a means for changing the width of the gap between the movable plate and the wall plate of the Glen tank by sliding the movable plate. .

[0003]

However, in the case of the former structure, when the grains are stored in the grain tank, the adjustment plate to which the load of the grains is directly applied is changed up and down. However, it has a drawback that it is difficult to adjust the displacement when it is displaced upward. Also, in the latter structure, the grain load is also applied to the movable plate, and when sliding upward, the grain on the fixed plate must be pushed away to operate, so the grain is also There was a difficulty in operating in the state where the water was stored. Therefore, when the adjustment plate is adjusted, it is necessary to reduce the grain storage amount in advance or to set the grain storage state in advance.

The present invention has been made in view of the above circumstances, and it is possible to easily adjust the flow-down supply amount of the stored grains to the screw conveyor even when the grains are stored in the grain tank. The purpose is to provide a possible Glen tank structure.

The two adjusting plates formed in a curved posture are provided so as to be able to change their relative positions around the rotation center, and the two adjusting plates are changed in relative position around the rotation center so that the clearance between the two adjusting plates and the wall plate is increased. It is characterized in that they are provided so as to overlap each other above and below the screw conveyor in a state where the width of the screw conveyor is changed.

(Operation) According to the structure of claim 1 of the present invention, the adjusting means is composed of the two adjusting plates formed in the curved posture along the rotation center of the screw conveyor, and the two adjusting plates are provided. Is provided so that the relative position can be changed around the rotation center, and the width of the gap with the wall plate can be changed by changing the relative position around the rotation center so as to vertically overlap with each other above the screw conveyor. Therefore, the load of grain on the screw conveyor is mainly applied at the upper and lower overlapping positions of the two adjusting plates, and the adjusting plates are relatively repositioned around the rotation center, that is, by the relative rotation. Since it is designed so as to move far and far with respect to the wall plate, it is easy to smoothly displace the grain when the adjusting plate moves.

(Effect) Therefore, according to the structure according to claim 1 of the present invention, due to the above-mentioned action, the relative movement of the adjusting plate causes the relative movement of the grain even when a large amount of the stored grain is in the grain tank. Since it can be performed in a state in which an unreasonable load such as pushing away is suppressed, the adjustment can be made very easily and the workability can be improved.

(Structure) The Glen tank structure according to claim 2 of the present invention is the structure according to claim 1, wherein one of the two adjusting plates is in a curved posture along a rotation center of the screw conveyor. It is configured as a fixed plate that covers the upper part of the screw conveyor, and only the other of the two adjustment plates is configured to be swingable around the rotation center so as to change the width of the gap with the wall plate. This is a characteristic configuration.

(Operation) According to the second aspect of the present invention, one of the two adjusting plates is a fixed plate that covers the upper side of the screw conveyor in a curved posture along the rotation center of the screw conveyor. Only the other of the two adjusting plates is configured to be swingable around the center of rotation so as to change the width of the gap between the adjusting plate and the wall plate, so it is fixed while the grain is stored in the grain tank. Although the load of the grain is applied to the plate, the movable adjustment plate can be oscillated around the rotation center while the load of the grain is suppressed by the fixed plate. . Further, the fixing plate can be installed and supported over the side walls of the Glen tank which face each other.

(Effect) Therefore, according to the configuration of claim 2 of the present invention, even when a large amount of the stored grains are in the grain tank, the relative movement of the adjusting plate causes an improper movement such as displacement of the grains. Since it can be performed in a state where various loads are suppressed, there is an advantage that adjustment can be performed very easily, workability can be improved, and the side wall of the Glen tank can be reinforced by installing the fixing plate.
