PRECOMPRESSOR AND REAR-MOUNTED COMPRESSION TYPE DUST CART

摘要

Disclosed are a precompressor and a rear-mounted compression type dust cart adopting the precompressor. The precompressor comprises a casing, a sliding plate (4) and a sliding plate hydro-cylinder (6). The sliding plate is mounted on a sliding plate slide way (7) at the inner side of the side plate of the casing through a sliding block (10, 14). One end of the sliding plate hydro-cylinder is hinged on the sliding plate, and the other end thereof is hinged at the inner side of the side plate of the casing. The rear-mounted compression type dust cart adopting the precompressor changes the operating mode of the sliding plate hydro-cylinder which is operated with a rodless cavity into a pushing mode by changing the direction and the position of the sliding plate hydro-cylinder and/or the structure of the casing of the precompressor, keeps the advantages of the internally-installed sliding plate hydro-cylinder and the externally-installed sliding plate hydro-cylinder, improves the operating speed, and reduces the system power.
