technical field

The invention relates to the technical field of construction waste treatment, in particular to a construction waste crushing device.

Background technique

Construction engineering refers to the planning, survey, design and construction, completion and other technical work and completed engineering entities for new, reconstructed or expanded buildings and ancillary structures, as well as the installation engineering of their supporting lines, pipelines and equipment , also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be built and materials must be started, and it can be realized through construction activities.

In construction projects, a large amount of construction waste will inevitably be produced, including excavated muck, concrete blocks, stones, brick fragments and asphalt blocks. Construction waste has extensive erosive effects on our living environment.

To further squeeze and crush the crushed garbage, and at the same time guide the crushed garbage to the upper end of the discharge port 3, so as to avoid the accumulation of the material, which can make the material move along the inclined plane and unload the material layer by layer.

Before screening, use the motor to drive the rotating roller 13 to rotate, so that the first conveyor belt 14, the second conveyor belt 17 and the third conveyor belt 20 are rotated and installed on the transmission bracket 12. The garbage is screened, so as to achieve the purpose of sorting and utilization of the garbage, and the conveyor belt 16 is used to realize the front and rear extension transportation, and the screened garbage is divided into streams.

During the screening process, since the inner diameter of the screening hole 15 at the front end is small, and the smaller particles stick and accumulate in the crushed garbage, a large vibration is required to achieve sufficient blanking, and the first vibrating seat 11 is used to drive the beating. The roller 33 rotates, so that when the beating roller 33 rotates, one end of the rotating rod 30 is hit by a rod extending on the beating roller 33, so that the rotating rod 30 rotates along the rotating bracket 34, and the other end of the rotating rod 30 is lifted upwards , so as to realize the hitting vibration of the first hitting ball 26 on the lower end of the first conveyor belt 14 .
