JPS5929514B2 - Discharge port opening/closing device for powder transport vehicle - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables the lid of the powder discharge port of a powder transport vehicle to be freely rotatable both vertically and horizontally. This invention relates to a powder and granular material discharge opening/closing device which can be opened and closed with a button and whose lid is restrained by a stopper with a bullet to ensure good sealing of the discharge opening.

Conventionally, there are two types of lids for powder discharge ports in powder and granular transport vehicles: those that open and close with a hinge on one side, and those that move back and forth in a sliding manner. Since the entire lid body rotates around the hinge, it can be used in cases where the gap between the powder discharge port installed at the rear of the vehicle and the powder intake port installed upright on the receiving side of the plant is narrow. It has the disadvantage that it cannot be fully opened, and the sliding type requires a certain amount of clearance to allow the lid to slide, which impedes sealing. Manufacturers and users alike have been seeking the development of an opening/closing device for the discharge port of a powder transport vehicle that requires less space and has an excellent sealing performance for the cover of the discharge port.

The present invention answers that need.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.A powder and granule transport vehicle A is equipped with a powder and granule discharge port B at the rear end of a powder and granule storage tank mounted on the vehicle body. On one side of the discharge port B, a sheath pipe 4 is fitted to a vertical shaft 3 fixed to the support member 2 and attached with a mounting nut 5, and a support plate 6 is fixed to the sheath pipe 4 to form a horizontal support shaft. T is provided protrudingly, and the discharge port cover 1 is attached to the horizontal support shaft T.
A stopper 8 that pivots a support shaft protruding from one end to enable the discharge port cover 1 to rotate vertically and horizontally, and holds the discharge port cover 1 and the discharge port B in an engaged state; , and an operating member 9 for operating the stopper 8 are mounted on a shaft at a position facing the support member 2 on one side of the discharge port B, and the stopper 8 is indexed by a bullet 10, and the reference numeral 11 is the lid 1. 12 is a knob of the operating member 9, 13 is a receiving port on the plant side, and 14 is a regulating member of the stopper 8.

Next, to explain how this equipment is used, the powder and granule discharge port B of the powder and granule transport vehicle A that has carried the powder and granules is faced to the position of the receiving port 13 on the plant side, and the operating member 9 is moved upward. When the stopper 8 is removed from the discharge port cover 1 to release the engagement relationship, the discharge port cover 1 rotates in the vertical direction about the horizontal support shaft T and rotates about the vertical shaft 3 into which the sheath tube 4 is fitted. It also rotates in the horizontal direction to open the discharge port B, allowing the powder and granules accommodated in the tank to fall into the receiving port 13 on the plant side.

In other words, the discharge port cover 1 is capable of combined movement in the vertical and horizontal directions, and the discharge port cover 1 can be rotated freely even in a narrow space according to the situation on the plant side to carry out the work of extracting powder and granules. It is something. After the work is completed, open the discharge port B again.
To close the outlet, the handle 11 is operated to bring the outlet cover 1 into contact with the lower surface of the outlet B, and the stopper 18 is pushed open against the bullet 10 and when engaged with the outlet cover 1, the cover 1 and It maintains an engagement relationship with the discharge port B to achieve a tight seal. In this way, the discharge port cover has one end on one side of the discharge port B,
It is rotatably supported vertically and horizontally,
The lid can be operated freely even in a narrow space; unlike a hinge type, it does not require a large space to open and close the lid, and unlike a sliding type, there is no sealing defect, and the mechanism is simple and easy to operate. It is an extremely excellent and advanced technical invention that has the following effects and has divine benefits for the transportation of powder and granular materials.
