Sand making machine provided with automatic jacking device

Abstract

The invention discloses a sand making machine provided with an automatic jacking device, belongs to the technical field of sand preparation and solves the problem that an existing device cannot adjustthe position of a hydraulic lifting device according to the position of a cover body. The sand making machine is technically characterized by comprising a stand column, a base, a sand maker and a cover plate, wherein the sand maker is fixedly mounted on the base, the cover plate is arranged at the top of the sand maker, the stand column is vertically arranged on the left side of the upper surfaceof the base, the bottom of the stand column is riveted with the base, a driving cavity is mounted at the top of the stand column and is in sliding connection with the stand column, a first hydrauliccylinder is arranged under the driving cavity and fixedly connected with the stand column through a bolt, and the telescopic end of the first hydraulic cylinder is hinged with the driving cavity. According to the sand making machine, the problem of difficulty in lifting of the cover plate is solved, meanwhile, the position of the lifting mechanism can be adjusted according to different positions and heights where the cover plate is located, so that the burden of workers is relieved, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of sand and gravel preparation, in particular to a sand making machine with an automatic jacking device. Background technique [0002] Sand making equipment is a kind of mechanical equipment specially used to produce sand for construction and road use. In addition, sand making equipment, crushing equipment, and screening and conveying equipment can be composed of sand making production lines, sand and gravel production lines and other sand making processes. Sand equipment can make various rocks, gravel, and river pebbles into construction sand with various particle sizes. The sand produced has uniform particle size and high compressive strength, which is far better than natural sand and ordinary hammer sand making machines. The sand is more in line with the construction requirements and can improve the construction quality. The equipment has many characteristics such as reliable performance, reasonable desig...
