Description

[Detailed description of the invention] Industrial application field The present invention allows the installation position of the elevator to be placed close to the main body of the dryer, even when the main body of the dryer equipped with an elevator is installed in a narrow workplace. The present invention relates to a device for changing the installation position of an elevator in a grain dryer that can be freely changed to a position where work can be performed properly.

Conventional technology In the past, grains placed in a hopper installed at one side of the lower part of the elevator were transported into the dryer body using the elevator, and then dried with dry hot air that circulated while the grains flowed vertically down the dryer body. The grain dryer is described in, for example, Japanese Patent Application Laid-Open No. 109765/1984 as a grain dryer for recirculating and flowing the grains in a heated state through an elevator to the main body of the dryer and drying them again with hot drying air to complete the drying operation. This is known and will be explained using FIG. 4. That is, 1 has a tempering tank 2 in the upper stage, a ventilation drying tank 3 in the middle stage that performs a drying action by blowing hot air during the process of flowing down the paddy flow path, and a lower stage in which the rice is somewhat dried in the ventilation drying tank 3. The main body of the dryer is in the shape of an oblong rectangular cylinder, in which take-out tanks 4 for taking out the grains are stacked one on top of the other in a three-dimensional manner. A conveyor 5 is installed horizontally, and a lower conveyor 6 is also installed horizontally at the bottom of the take-out tank 4 for transporting the grains to the lower part of the elevator 7.
The elevator 7 is attached to one side of the dryer main body 1, and the discharge gutter 8 provided at the upper part of the elevator 7 is on the carry-in side of the upper conveyor 5, and the discharge side of the lower conveyor 6 is on the lower part of the elevator 7. It is connected.

Problems that the invention aims to solve By the way, conventional elevators of this type were installed at a predetermined position on the front or rear side of the dryer body, and the installation position of the elevator was not adjusted relative to the dryer body. , it is not structured so that it can be changed at will.

Therefore, when drying grains by installing the main body of the dryer in a narrow drying work area, it is necessary to have a fairly large space around the hopper to efficiently transfer the grain to the hopper. As a result, there was a problem in that a predetermined amount of grain could not be quickly carried into the main body of the dryer and drying operations could not be carried out efficiently.

Means for solving the problems The present invention solves the above problems, and includes:
The contents will be explained below using FIGS. 1 to 3 corresponding to the embodiment.

That is, an upper conveyor 105 and a lower conveyor 107 are provided above and below the dryer main body 101. The carry-in side of the upper conveyor 105, the carry-out side of the lower conveyor 107, and the discharge gutter 114 and supply gutter 115 provided at the upper and lower positions of the elevator 109, which is equipped with a hopper 116 on one side of the lower part, are connected to a ring-shaped connecting metal fitting on one side. 120, 126 to the inlet side of the upper conveyor 105 and the outlet side of the lower conveyor 107, and the other side is connected to the discharge gutter 114 of the elevator 109 and the supply gutter 1 via annular connecting fittings 122, 128.
The elevator 109 is connected to the dryer main body 101 by an upper relay conveyor 117 and a lower relay conveyor 123, which are rotatably fitted to the dryer body 15, respectively.
It is constructed so that its installation position can be changed freely.

Function Now, one side connects the inlet side of the upper conveyor 105 provided at the upper position of the dryer main body 101 and the discharge gutter 114 provided at the upper position of the elevator 109 on the inlet side of the upper conveyor 105 via the annular connecting fitting 120. The other side is rotatably fitted into the annular connecting fitting 1.
The upper relay conveyor 117 is rotatably fitted in the discharge gutter 114 of the elevator 109 through a cable 22, and the lower conveyor 107 provided at the lower part of the dryer main body 101 is connected to the discharge side of the elevator 10.
9 is connected to the lower conveyor 107 via an annular connection fitting 126 on one side.
The elevator 109 and the upper At the same time as the relay conveyor 117 and lower relay conveyor 123 are operated, grain is loaded into the loading hopper 116. Then, the grains are fried by the elevator 109, then supplied to the upper relay conveyor 117 through the discharge gutter 114, and further conveyed to the carry-in side of the upper conveyor 105, and then carried into the dryer main body 101. .
With the above operations, a predetermined amount of grain is transferred to the dryer body 1.
01, the drying operation starts, and the grains are dried by the circulating dry hot air, and the lower relay transfer machine 123 transports the grains in a heated state by the lower conveyor 107, and then from the supply gutter 115 to the elevator 109. After the grain is lifted again by the elevator 109, it is transferred to the drying main body 10 via the discharge gutter 114, the upper relay conveyor 117, and the upper conveyor 105.
1, and dried again with dry hot air. Therefore, by repeating the above circulation flow action many times, the grain is finished and dried to a predetermined moisture content.

By the way, during the drying work as mentioned above,
The drying work area is narrow or the hopper 116
Since this position is inappropriate for the grain tensioning operation, there may be cases where the grain tensioning operation cannot be accomplished efficiently. In such a case, lift the elevator 109 and move each ring connecting metal 120,
After rotating left and right around 122, 126, and 128 to change the installation position to the optimal position,
If the same grain tensioning work as described above is performed, not only efficient grain tensioning work but also grain drying work can be accomplished with high efficiency.
