The present invention relates to a grain management apparatus. More specifically, the present invention relates to an apparatus for preventing breakage of grains generated during grain transfer and automatically adjusting the capacity management of raw materials conveyed to the grain storage tank.

A number of elevators are used in a facility that performs a series of treatments such as rice, barley, etc. after harvesting, drying, peeling, milling, and sorting, and the elevator and the storage tank are directly connected by a cylindrical or polyhedral chute to transport them. When the raw material discharged from the gas enters the storage tank through the chute pipe, it collides with its inner wall and is destroyed.

In addition, through the monitoring window installed in the storage tank during the conveyance, the amount of grain conveyed by the eye is visually measured or when the required alarm is reached and the required level is reached, the conveyance is stopped. However, when the monitoring is neglected and the observation is not made or the alarm sound is not heard, the capacity of the storage tank is exceeded, and the raw materials are accumulated in all the electricity, causing problems such as transportation stoppage due to burnout of the motor or insulation of the bucket belt.

The present invention improves the above-mentioned problems by installing a predetermined bypass conduit 2 at the end of the chute pipe, and installing sensing devices 9, 9a, 9b, etc. connected to valves and motors in each storage tank.

Specific embodiments of the device of the present invention will be described with reference to the accompanying drawings.

The shock absorber of the present invention is shown in FIGS. 1 and 2, and the bypass conduit 2 is installed on the left or right side of the proximal end 3 of the main conduit 1, and the bottom part 4 of the main conduit 4 is provided. ), An outlet 5 is formed.

The above conduits are connected to the outer portion of each of the storage tanks 6, 6a, 6b, 6c, and 6d and are connected to the lifting device 7 and the guide conduit spoked. On the other hand, in the storage tanks 6, 6a, 6b, 6c, and 6d, sensing devices 9, 9a, 9b, etc., are provided on the upper limit line or the central portion where a certain amount of grains are accumulated. The sensing devices 9, 9a, 9b may be of a rotary type having a blade 12 at the end of the shaft 11 of the motor 10 or a capacitive type having the sensor 13 attached to the shaft of the motor 10. These detectors were attached at the point of time when the detectors were operated, with sufficient allowance for the raw material to enter the reservoir during the transfer between the detectors and the equipment braked in the previous process (eg cylinder shutters, etc.). Other devices are the same as the general grain management devices, so description is omitted.

The operation of the device of the present invention having the above structural features will be described.

First, in the case of the shock absorber, the grains 14 are conveyed at a constant speed from the elevator as shown by the arrow of FIG. 2 and initially, grains are accumulated at the tip 1a of the main pipe 1. The reason is that the discharge port 5 is less discharged than the amount of grain to be conveyed. As a result, as shown in FIG. 2, the grain 14 has a bypass attached to the side surface when it exceeds the negative volume of the tip 1a. Out of the conduit (2).

In this case, since the conveyed grains collide with the grains 14 stacked in a suitable space, there is little destruction than when directly colliding with the metal conduit wall. When the grain transfer from the elevator is stopped, the grain loaded on the tip portion 1a is gradually discharged and removed from the discharge port 5 and finally completely removed.

The above shock absorber is attachable to the leading end of the transfer conduit attached to all the storage tanks shown in the schematic diagram of FIG.

The detection device (9, 9a, 9b, etc.) installed in the existing storage tanks (6, 6a, 6b, 6c, 6d) together with the shock absorber of the present invention allows the cylinder shutter to be closed immediately upon receiving a signal. Since the bucket contains raw materials, it was not stopped so that the raw materials contained in the bucket did not overflow. In the case of a belt conveyor, if it stops, if a certain amount comes between the storage tank and the conveyor, it does not overflow within a certain angle of repose.

Therefore, there is no fear that grains above a certain level will be transferred to the storage tank, thereby eliminating unnecessary motor burnout and belt insulation.
