Body of powder material transporting tank truck

Abstract

The invention relates to a body of a powder material transporting tank truck, comprising a cover mechanism for covering a powder material feeding opening. The cover mechanism comprises an upper cover, a compressing device and at least two compressing claw devices; the upper cover is articulated with the body of the powder material transporting tank truck; the compressing device comprises screws, compressing nuts sleeved on the upper ends of the screws and matched with the screws, downward compressing pieces which are fixedly connected with the compressing nuts and are consistent with the compressing claw devices and rotary handles articulated with the compressing nuts; each compressing claw device comprises a base, a compressing claw and a compressing and adjusting bolt arranged on the compressing claw and near to the base; one end of the compressing claw is articulated with the base, and the other end is free; when the powder material feeding opening is covered, the rotary handles rotate by taking the screws as the center to make the compressing nuts move downward, the downward compressing pieces downward compress the free ends of the corresponding compressing claws so that the lower ends of movable screw rods support against the upper cover. The overall height of the body of the powder material transporting tank truck can be lowered through lowering the height of the cover mechanism.

Description

technical field [0001] The invention relates to a tank body used for a tank truck for transporting powder materials, in particular to a material cover mechanism for closing a material inlet in the tank body. Background technique [0002] Generally speaking, the powder material transport tanker is a tanker used to transport powdery or granular materials such as cement or grain. Since a certain pressure must be maintained in the tank body of the powder material transport tank truck, it is necessary to ensure that the material cover mechanism can well seal the feed port so that the feed port will not leak. [0003] figure 1 A schematic cross-sectional view of a material cover mechanism and a material inlet in a tank body of an existing powder material transport tanker is shown. Such as figure 1 As shown, a circular feeding port 2 is formed on the top of the tank body 1, and a material cap mechanism 3 is arranged on the feeding port 2. The material cover mechanism 3 comprise...

AI Technical Summary

Problems solved by technology

[0008] Although the above-mentioned material cover mechanism can conveniently close the feed inlet of the tank car, there is a problem that the height of the material cover mechanism is too high, resulting in the super high height of the tank car and the problem that it cannot be loaded.
