Description

Filler and post-loading compressed garbage truck

Technical field

The present invention relates to the field of sanitation vehicle technology, and in particular to a filler and a post-loading compressed garbage truck using the same. Background technique

Because the post-loading compressed garbage truck has mature technology, high work efficiency, simple operation and maintenance, and good adaptability, the post-loading compressed garbage truck is widely used and becomes the mainstream of the market. The rear-loading compressed garbage truck is mainly composed of a filler, a garbage bin and a pusher, the compression mechanism is a filler, and the filler is composed of a casing, a slide plate and a scraper, and the slide plate and the scraper are respectively composed of a slide cylinder and Scraper cylinder drive. The existing rear-mounted compression garbage trucks are arranged from the slide cylinders: the slide cylinders are built-in and the slide cylinders are externally mounted, each having advantages and disadvantages.

Specifically, the built-in characteristics of the slide cylinder are: the slide cylinder is disposed inside the scraper cylinder in the filler, the cylinder end of the slide cylinder is connected with the upper beam of the filler, and the rod end of the slide cylinder is connected with the slide. The external characteristics of the slide cylinder are: the slide cylinder is arranged outside the shell of the filler, the cylinder end of the slide cylinder is connected to the outer side of the housing of the filler, and the rod end of the slide cylinder is connected to the slide through the long groove on the housing. .

The built-in slide cylinder does not need to be grooved in the side plate of the shell of the filler, and has a complete structure and beautiful appearance; since it has a rod cavity during compression, it is a pulling method. If the hydraulic system pressure is to be the same as the external output, the cylinder needs to be enlarged; if it is to be the same as the external speed, the hydraulic system flow needs to be increased; the result is that the required power is large.

The external manufacturing process of the slide cylinder is complicated, and the dimensional accuracy of the slide is difficult to control. The housing of the filler has a long groove, the strength is reduced, and the shape is disordered. It is a rodless cavity during compression work and is a push mode. If the hydraulic system pressure is the same as the built-in output, it can be reduced. Small cylinder; speed efficiency is improved under the same hydraulic system flow as the built-in type.
