[Prior Art] Generally, a powder dropping device for loading powder onto a truck etc. has a cylindrical chute placed on top of the truck etc.
The powder and granules sent from the conveyor pass through this chute and fall onto the track. This chute is designed to be pulled up in sequence according to the height of the powder and granules accumulated on the track, but this operation is performed visually by the worker. For this reason, a gap may be formed between the lower part of the chute and the powder and granules, and as a result, dust is generated by the falling powder and granules, causing not only loss of the powder but also pollution problems.

For this reason, several methods have been proposed to suppress dust generation. In Utility Model Application No. 56-84510, a dustproof sheet is provided at the bottom of the chute to suppress the scattering of dust. However, this device requires a moving device that moves the chute up and down in accordance with the height of the pile of discharged powder and granules. Such problems are discussed in Utility Model Application Publication No. 56-113097,
The same can be said of Utility Model Application No. 61-151932, Utility Model Application No. 64-506, etc. In Japanese Utility Model Application No. 57-96107, a dustproof sheet is provided at the bottom of the chute, and the chute has a double structure to suck in dust. However, in addition to the above-mentioned problem, this method also has the problem of increasing the size of the chute. In Japanese Utility Model Application No. 58-7711, a hood portion is provided at the lower part of the chute, and this hood portion is provided with multiple internal and external partitions to prevent dust from scattering. This device also requires a device to move the chute up and down, and when a crosswind blows, the hood part flies up and the dust prevention effect cannot be achieved. Such problems have been discussed in Utility Model Application No. 58-7712, Utility Model Application No. 61-151932, and Utility Model Application No. 61-1989. The same can be said of No. 165939.

According to this device, a screw-type powder extruder that covers the inner surface of the chute is installed at the chute outlet, so that if the tip of the chute is inserted into the powder that has already been deposited, the falling powder can be removed easily. This eliminates the problem of pollution by keeping dust generated by the body only within the chute. In addition, when extruding powder and granules, a thrust acts between the powder and granules supplied by the screw-type powder and granule extruder and the already deposited powder, and this thrust causes the chute itself to rise. It is possible to drop the powder in a constant state, that is, in a state in which the tip of the chute is always buried in a certain amount in the pile of accumulated powder. In this case, in order to move the chute upward by the thrust, there is no need to perform a separate movement operation of the chute. Furthermore, when moving the supply location after supplying a certain amount of powder or granules, if the extruder operation is stopped, the extruder screw will function as a lid at the bottom of the chute opening.
Powder inside the chute does not leak and no dust is generated.

The granular material G conveyed by the conveyor C is first cylindrical part 11,
It passes through the second cylindrical part 12 and the third cylindrical part 13 following it, and reaches the fourth cylindrical part 14 at the lower end. Here, the granular material is extruded and discharged from the lower part of the chute 1 by the rotating screw of the extruder 2. The lower part of the opening of the chute is inserted into a pile of powder and granular material G piled up on the truck, and the discharged powder and granular material is forcibly pushed out within the piled powder and granular material G that has already been discharged. be done. Therefore, the discharged granular material is not exposed to the outside air, and no dust is generated from the granular material. Furthermore, thrust is generated when extruding powder and granules, but
The weight of the chute 1 is balanced by a balance weight 4, and this thrust can reliably lift the chute 1 upward. The difference in weight between the chute 1 and the balance weight 4 is such that the lower end of the chute can be placed into the pile of powder to prevent dust generation, and the chute can be pushed upward by the thrust that pushes out the powder. To the extent that For example, it is preferable to make the balance weight 4 about 10 kg lighter. Furthermore, the fins 8 on the outer periphery of the fourth cylindrical portion 14 have the function of preventing the chute 1 from rotating due to the action of the drive motor, etc., and improving its stability.

[Effects of the Invention] As explained above, according to the present invention, by providing a screw-type powder extruder that covers the inner surface of the chute at the chute outlet, the tip of the chute is removed from the already deposited powder. By inserting the chute, the dust generated by the falling powder can be confined only to the inside of the chute, and the problems of powder loss and pollution can be solved. In addition, thrust is exerted by the extrusion of the powder and granules supplied by the screw-type powder and granule extruder, and this thrust causes the chute to rise and remain in a constant state, that is, in the pile of powder and granules that have been piled up. Powder can be dropped while the tip of the chute is always immersed. In this case, since the chute is moved upward by the thrust, there is no need to perform a separate movement operation of the chute, and the apparatus is simple. Furthermore, when moving the supply location after supplying a certain amount of powder or granular material, if the extruder operation is stopped, the screw will cover the chute and the powder or granular material in the chute will not leak. This can be achieved by solving the problem of dust generation after completion.
