DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain storage room having a device for detecting the amount of stuffed grain.

[0002]

2. Description of the Related Art There is known a grain storage chamber in which a sticking amount sensor which is made of a conductive elastic body or the like and detects a sticking grain amount by a pressure caused by the grain sticking is fixed to a side wall.

[0003]

As described above, in the grain storage chamber in which the filling amount sensor is fixed to the side wall, the assembling amount sensor is connected to the side wall of the grain storage chamber when assembling the grain storing chamber. In order to fix to the grain storage work, it is necessary to work in the grain storage room, so that the mounting work is very troublesome.

Further, since the extension sensor is configured to be mounted in the vertical direction of the side wall, a large number of mounting tools are required correspondingly, so that the number of steps required for the mounting operation is increased.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent the wear of the penetrating amount sensor from being increased and to provide a grain storage chamber which is easy to assemble by devising a mounting method and a mounting position of the penetrating amount sensor. And

[0006]

The present invention employs the following technical means in order to solve the above technical problems. That is, a diffusion plate 38 for diffusing grains transported by the transfer spiral is provided at the upper center side of the storage chamber 7 formed by the machine wall 4, the transfer gutter 5 containing the transfer spiral, and the ceiling plate 6. At the same time, a plurality of conductive members are provided in the vertical direction of the film plate, and the conductive members are sequentially energized from below by the pressing action of the embedded grains in the storage chamber 7 to detect the amount of the embedded grains. The grain storage room is characterized in that the detection device is provided near the machine wall 4 so as to be suspended from the ceiling plate 6.

[0007]

First, the operation of the embedding grain detecting device will be described. As the grains conveyed in the conveying gutter 5 by the conveying spiral are diffused into the storage chamber 7 by the diffusing plate 38, they are stuck.
The pressing action of the grains is applied to the film plate. For example, when the conductive member provided for each of the predetermined number of stones (8 stones, 12 stones) is reached, the pressing action causes electricity to flow, and the grains stick to the number of stones. Detect that it has been lost.

In assembling the grain storage room, the film plate having the above-described function is suspended from the ceiling plate 6 so as to be located near the machine wall 4.

[0009]

According to the present invention, the position of the spreader 38 and the position of the spilled grain detecting device can be improved by forming the spilled grain detecting device in the vicinity of the machine wall 4 so as to be suspended from the ceiling plate 6. Since the relationship can be set apart, when the diffusion board 38 diffuses the grain into the storage chamber 7, the impact caused by the collision with the stuffed grain detection device can be further reduced. Therefore, while installing the stuffed grain detection device, while preventing the increase in wear of the stuffed grain detection device,
There is no need to attach to the side wall, and the attaching operation is simplified, and the number of fixtures can be reduced. Therefore, it is possible to make the grain storage room easy to assemble.
