Efficient multi-stage rock crushing equipment for highway construction

Abstract

The invention discloses an efficient multi-stage rock crushing equipment for highway construction. The efficient multi-stage rock crushing equipment for highway construction comprises a machine body,a mixed cavity, a hydraulic cylinder, a milling block and a conveying cavity; a material inlet is formed in the right side of the machine body; the mixed cavity is formed above the right side of the cavity of the machine body; the top of the right side of the mixed cavity is in communication with the material inlet; first material guide plates are obliquely arranged under the left side of the mixed cavity; two first material guide plates are arranged; a first screen mesh is arranged between the lower ends of the first material guide plates; the milling block is arranged in a position right against the top of the first screen; a telescopic rod is welded at the top of the milling block; a hydraulic cylinder is fixedly connected to the upper end of the telescopic rod; and a conveying cavity is formed in the bottom of the cavity of the machine body. According to the efficient multi-stage rock crushing equipment for highway construction, the design is reasonable; rock blocks can be screenedand crushed in multiple stages; the working efficiency is high; the crushing speed is high; the safety coefficient is high; safety accidents in manual operation are avoided; the life safeties of people are furthest guaranteed; and the working burdens of people can be reduced.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular to a high-efficiency multi-stage crushing equipment for road construction. Background technique [0002] The pulverizer is a machine that crushes large-sized solid raw materials to the required size. According to the size of the crushed material or the crushed material, the pulverizer can be divided into a coarse crusher, a pulverizer, and an ultrafine pulverizer. There are four types of external forces on solids: shearing, impacting, rolling, and grinding. Shearing is mainly used in coarse crushing (crushing) and crushing operations, and is suitable for crushing or crushing operations of tough or fibrous materials and bulk materials; impact is mainly used in crushing operations, and is suitable for crushing brittle materials; rolling It is mainly used in high-fineness crushing (ultrafine crushing) operations, and is suitable for ultrafine crushing operations on...

AI Technical Summary

Problems solved by technology

[0003] In highway construction, crushed stones will be used to pave the base layer. The size of crushed stones is also different for different road grades. At this time, we will crush crushed stones of different sizes and classify the crushed stones. However, the existing crushing equipment has some defects in the process of use. For example, it is not possible to screen and subdivide crushed stones of different sizes, and it is very wasteful to mix them together; The effect is not good, and it is easy to cause the particle size of the stones to be inconsistent, thus affecting the normal construction of roadbed bedding
