Abstract

The invention discloses a blow-down device which comprises a blow-down port (2) formed in a blow-down pipe (1) and a door body (3) used for closing and opening the blow-down port. The door body is pivoted with the blow-down pipe through a rotating shaft (31), the blow-down device further comprises a rotating assembly used for opening or closing the door body and a locking assembly used for locking or unlocking the door body when the door body is closed. The invention further discloses a feces-sucking trolley which is provided with the blow-down device. The cylinder diameter needed by an air cylinder is reduced through the improvement of the structure of the blow-down device, the problem that the door body is difficult to open and close due to pollution caused by pollutants is solved, and the door body can be conveniently opened and closed in an automatic mode and a manual mode.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a sewage discharge device and a fecal suction truck. Background technique [0002] A sewage discharge device is installed on the fecal suction truck to extract and discharge sewage. Existing fecal suction vehicle blowdown device has two kinds of switch modes, manual and automatic. Among them, the manual switch mode is used less and less due to the reliability of the seal and the reasons of cleanliness and hygiene. [0003] attached figure 1 Shown in is the structure diagram of the sewage discharge device in the prior art. As shown in the figure, the sewage pipe 1 has a sewage outlet, and the door body 3 is used to open and close the sewage outlet. Wherein, the opening and closing of the door body 3 is realized by the air cylinder 101 . A locking pin 102 is connected to the cylinder 101 , and the cylinder 101 can control the extension and retraction of the locking pin ...
