Building material smashing and damping device

Abstract

The invention discloses a building material smashing and damping device. The building material smashing and damping device is provided with a smashing chamber, a grinding chamber and a feeding chamber; building materials are extruded and smashed in the smashing chamber through a gear group and then are further grinded through the grinding chamber; a sieve plate is slantly arranged between the smashing chamber and the grinding chamber; by arranging a front elastic base, a rear elastic base and a universal rotating shaft bracket on the lower portion of a machine body and by utilizing vibration generated when a motor drives the gear group to rotate so as to drive the machine body, the sieve plate is made to vibrate, so that the smashed building materials are better sieved; and according to the design, a sieve plate vibration device is not required to be arranged, the equipment mechanism is more simplified, meanwhile, buffering can exist between the machine body and a supporting frame, andnoise during working of the equipment is reduced.

Description

technical field [0001] The invention relates to a building material processing device, in particular to a building material crushing and shock absorbing device. Background technique [0002] Accommodation is inseparable from houses. my country is a country with a large population in the world. In order to solve people’s housing and transportation problems, many buildings are newly built every year. Rational use of garbage will be a huge wealth, and will bring huge income to the development of society and cities. On the contrary, it will be a burden to the development of cities and cities, and become the chief culprit of polluting the environment. According to the concept of circular economy, it is feasible to use construction waste as a raw material. [0003] The Chinese invention patent specification CN106622473A announced on May 10, 2017 discloses a construction waste crushing device, which squeezes building materials through two crushing shafts placed in gaps and with spi...

Problems solved by technology

However, the two crushing shafts in the device are fixed. When the particle size of the construction waste is large, the fault of the crushing shaft is prone to jamming, and even the rigidity of the spiral crushing lines on the crushing shaft will be destroyed, which reduces the service life of the device.

At the same time, in order to increase the applicability of the crushed building materials, the particle size of the crushed construction waste needs to have certain requirements. The smaller and more uniform the particle size, the better the applicability of the materials obtained after crushing. At present, the existing construction waste crushing devices only squeeze and crush the construction waste, and it is difficult to obtain products with uniform particle size.

Although the product with uniform particle size can be obtained by adding a sieve plate at the discharge port, in order to better sieve the pulverized product, the sieve plate needs to be vibrated, resulting in a large noise of the device
