Problems solved by technology

Usually, in order to unload the residual material as much as possible, the driver will repeatedly shrink the hydraulic cylinder, so that the carriage vibrates to shake off the residual material, but this operation will cause greater damage to the hydraulic cylinder and the carriage; sometimes, in order to reduce For damage to the hydraulic cylinder, the driver will hit the surface of the carriage with a shovel to shake off the remaining materials. This method will also cause damage to the carriage and is inconvenient to operate

Abstract

The invention relates to the field of transportation and specifically discloses a freight container. An air collection cavity is arranged in a front board of the container; a telescopic board is arranged in the container; one end of the telescopic board is hinged to a bottom board at the rear part of the container and the other end of the telescopic board is capable of sliding vertically at the front board; the two sides of the telescopic board respectively abut against a left side board and a right side board; a return spring is arranged under the telescopic board; a compression cavity is formed under the telescopic board; the compression cavity communicates with the air collection cavity; the telescopic board comprises a first board and a second board which are connected to each other ina sliding manner; an inner cavity is arranged in the first board; a piston fixed to the end of the second board is arranged in the inner cavity; an air flow passage which communicates with the innercavity is arranged in the second board; a pressing valve for communicating the air collection cavity with the air flow passage is arranged at the bottom of the front board; the left side board and theright side board are provided with air outlets; the left side board and the right side board are provided with slideways communicating the air collection cavity with the air outlets; and blocking-upblocks for isolating the air collection cavity from the air outlets when the container is in a horizontal state are arranged in the slideways. The freight container facilitates the removal of residualmaterials.

Description

technical field [0001] The invention relates to the transportation field, in particular to a freight carriage. Background technique [0002] When transporting gravel materials and dust materials, dump trucks are often used to carry them. A dump truck refers to a vehicle that unloads goods by itself through hydraulic or mechanical lifting; the frame of the dump truck is provided with a compartment, and the compartment is surrounded by a front panel, a rear panel, left and right side panels and a floor to form a box for loading materials. The rear part of the compartment floor is hinged on the frame, and a hydraulic cylinder is installed on the frame. The piston rod of the hydraulic cylinder is hinged to the front end of the floor, so that when the hydraulic cylinder is extended, the front end of the compartment is lifted, and the rear end of the compartment is relatively The frame rotates, so that the carriage is tilted, and the rear panel is opened at the same time, and the...
