Efficient stone crushing and screening device for constructional engineering

Abstract

The invention belongs to the field of civil engineering mechanical equipment, and particularly relates to an efficient stone crushing and screening device for constructional engineering. The efficientstone crushing and screening device for constructional engineering comprises a device shell body, the upper end of the device shell body is communicated with a feeding hopper, a first motor is installed on the inner bottom face of the device shell body, a stone crushing barrel body is rotatably connected to the inner side wall of the device shell body, the center of the bottom of the stone crushing barrel body is sunken downwards and is fixedly communicated with a discharging pipe, the lower end of the discharging pipe penetrates through the bottom face of the device shell body and is rotationally connected with the device shell body, the first motor is in transmission connection with the stone crushing barrel body, a second motor is installed at the upper end of the device shell body, and vibrating blocks are arranged in the stone crushing barrel body. According to the efficient stone crushing and screening device for constructional engineering, crushing can be carried out through collision among all stones and repeated collision of the vibrating blocks, so that the crushing effect is good, and the efficiency is high; and small stones obtained after crushing is completed are screened out through the centrifugal force of rotation of the crushing barrel body, so that the sizes of the stones are uniform, and the quality of civil engineering construction is guaranteed.

Description

technical field [0001] The invention belongs to the field of civil construction machinery and equipment, and in particular relates to a high-efficiency gravel screening device for construction engineering. Background technique [0002] With the expansion of the scale of civil construction engineering, construction tools, equipment, and machinery are also developing towards multi-variety, automation, and large-scale development. Therefore, it is very important to efficiently crush stone raw materials during the construction of civil engineering projects. [0003] In the prior art, impact or centrifugal crushers are often used to crush stone raw materials. However, most of these crushing methods have simple structures, limited crushing effects, low work efficiency, and uneven sizes of crushed stones, which affect civil engineering. Progress of building construction. [0004] To this end, we propose a high-efficiency gravel screening device for construction to solve the above...
