Cargo tank tail gate sealing mechanism and dumper

Abstract

The invention provides a cargo tank tail gate sealing mechanism. The cargo tank tail gate sealing mechanism comprises a cargo tank body, a cargo tank tail gate and a sealing strip; and the top end ofthe cargo tank tail gate is hinged to the cargo tank body, the sealing strip is arranged at the contact part of the cargo tank body and the cargo tank tail gate, one of the cargo tank body and the cargo tank tail gate is provided with a first magnetic body, the other of the cargo tank body and the cargo tank tail gate is provided with a second magnetic body, the first magnetic body and the secondmagnetic body are arranged on the opposite faces of the cargo tank body and the cargo tank tail gate correspondingly, and the first magnetic body and the second magnetic body are mutually exclusive. According to the cargo tank tail gate sealing mechanism, the first magnetic body and the second magnetic body are mutually exclusive and are used for preventing opposite motion between the cargo tank body and the cargo tank tail gate, accordingly, impact abrasion to the sealing strip when the cargo tank tail gate is closed can be reduced, the service life of the sealing strip is prolonged, and thesealing effect of a cargo tank is effectively improved. On the other hand, the invention provides a dumper provided with the cargo tank tail gate sealing mechanism.

Description

technical field [0001] The invention relates to the technical field of construction machinery, and relates to a truck, in particular to a cargo box tailgate sealing mechanism and a dump truck equipped with the cargo box tailgate sealing mechanism. Background technique [0002] A dump truck, also known as a dump truck, refers to a vehicle that unloads goods by itself through hydraulic or mechanical lifting. The compartment of a dump truck is divided into two types: backward tipping and sideways tipping. The movement of the piston rod is controlled by the operating system. Backward tipping is more common. Dump truck is a kind of transportation vehicle that can unload goods by itself. It has the characteristics of automatic unloading and strong mobility, which can improve the efficiency of cargo loading and unloading, save labor and time costs, and has become one of the most important vehicles for cargo transportation today. It has been used in Widely used in urban constructio...

AI Technical Summary

Problems solved by technology

[0004] During normal operation, the unloading door needs to be opened / closed frequently. In order to prevent cargo from leaking between the unloading door and the container body, a sealing strip is usually installed at the connection between the unloading door and the container body, that is, between the container body and the container body. A rubber strip is set at the door contact, and the cargo box body and the unloading door are pressed tightly by the self-weight of the unloading door and the lock hook to realize the sealing function. The collision of the container body creates a greater impact on the rubber strip, which makes the rubber strip wear faster
