M-cavity sand making machine

Abstract

The invention discloses an M-cavity sand making machine, and relates to the field of sand making machines. The M-cavity sand making machine comprises a machine body and a motor, the machine body comprises a shell body and a rotating device, the shell body comprises a feeding port, a top plate, a cylinder body, a base and a discharging port which are sequentially arranged from top to bottom, and awear-resistant lining plate is arranged in the cylinder body; the rotating device comprises a rotating shaft, a conical boss type upper rotating frame, a connecting spacer bush and a cylindrical lowerrotating frame are sequentially and fixedly arranged on the rotating shaft, a wear-resistant plate hammer a is arranged on the upper rotating frame, and a wear-resistant plate hammer b is arranged onthe lower rotating frame; one end of the rotating shaft is inserted into the center of the base and is movably connected with the base, the lower rotating frame is arranged close to the base, the other end of the rotating shaft penetrates through the center of the top plate and is movably connected with the top plate, a belt wheel a is fixedly arranged at the end of the rotating shaft, and a beltwheel b is fixedly arranged at the end of an output shaft of the motor; and the M-cavity sand making machine further comprises a belt, and the belt wheel a and the belt wheel b are in transmission connection through the belt. According to the M-cavity sand making machine, materials can be fully crushed in the machine, the sand making efficiency is high, moreover, discharging is smooth, manual operation and screening are not needed, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of sand making machines, in particular to an M-cavity sand making machine. Background technique [0002] With the rapid development of the construction industry, the demand for sand and gravel is increasing. However, natural sand and gravel are non-renewable resources in a short period of time. After years of development, natural sand and gravel are almost exhausted, and the excavation of sand and gravel has caused serious damage to resources and the environment. In order to meet people's needs for sand and gravel, industrial sand making machines have emerged as the times require. Sand making machines can crush rocks, ores and other stones into industrial sand, which can be used instead of natural sand. [0003] The sand making machine is a kind of vertical shaft crusher. The material enters the body from the feed port, and then the material is struck by the blow bar, impacted by the material and the material, impact...

AI Technical Summary

Problems solved by technology

The labor intensity of the operator of this equipment is high, and the efficiency of sand making is low

At present, there are also sand making machines that set a screening mechanism in the machine and control the size of the material particles by reducing the distance between the mechanism and the inner liner of the body. Unsmooth sand occurs
