Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a multi-stage adjustable concrete crusher. Background Art

[0002] By screening concrete waste, concrete of different particle sizes can be separated and reused in a targeted manner, thereby maximizing the efficiency of resource utilization. Reasonable particle classification can ensure the density and mechanical properties of concrete mix materials and ensure the quality and stability of concrete structures.

[0003] Although multi-stage screening can be performed during the crushing and screening process, the screening structure cannot be adjusted, resulting in screening only within a fixed specification range. Particles of different specifications are used in different recycling and reuse production processes, and the multi-stage screening structure that cannot be adjusted has low flexibility. Therefore, those skilled in the art provide a multi-stage adjustable concrete crusher to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-stage adjustable concrete crusher in view of the problems existing in the background technology.

[0006] Preferably, the inner and outer walls of the mounting ring are provided with rubber blocks distributed in an annular array, and the rubber blocks are closely fitted with the inner and outer walls of the sieve cylinders 1 and 2. The rubber blocks are fitted with the outer walls of the sieve cylinders 1 and 2 inserted in the mounting ring, thereby improving the stability of the sliding insertion of the sieve cylinder 1.

[0007] Preferably, multiple groups of reinforcing ribs are arranged between the mounting rings in a circular array and connected to the mounting cylinder, and the mounting rings with the same radius are connected by the same group of reinforcing ribs. The mounting rings with the same radius are fixed by the reinforcing ribs so that the mounting rings are fixed on the mounting cylinder, and the mounting rings support the first screen cylinder and the second screen cylinder.

[0008] Preferably, a guide plate 3 is provided below the mounting cylinder, a guide plate 2 fixed to the upper end of the mounting frame is suspended on one side below the screen cylinder 2, and a guide plate 1 fixed to the upper end of the mounting frame is suspended on one side below the screen cylinder 1. The guide plate 3 receives and guides the particles after the concrete is crushed and discharged from the screen cylinder 2. The functions of the guide plate 2 and the guide plate 3 are the same. Because of the composition of multiple groups of mounting rings, a cylindrical screening structure can also be installed outside the screen cylinder 2. At this time, the guide plate 2 guides the particles discharged from the screen cylinder 2, and the guide plate 3 guides the particles discharged from the outermost screening structure. The guide plate 1 receives and transports the particles discharged from the screen cylinder 1.

[0009] Preferably, the upper end of the bracket is provided with relatively distributed guide grooves, and a gap is provided between the guide grooves, and the gap corresponds to the center of the two groups of crushing rollers. During the concrete crushing process, the concrete is transported and guided to the crushing rollers through the guide grooves, and enters the crushing rollers through the gaps for extrusion and crushing.

[0010] Preferably, the outer wall of the installation tube is sleeved with rotating rings distributed at equal intervals, and the upper end of the installation frame is provided with rotating seats distributed at equal intervals, and the rotating rings are rotatably installed inside the rotating seats. The installation tube rotates inside the rotating seats through the rotating rings to rotatably support the installation tube.

[0011] Preferably, the outer wall of the mounting ring is sleeved with a gear ring, a motor 1 is arranged on one side of the upper end of the mounting frame, and a gear meshing with the gear ring is arranged at the output end of the motor 1. The motor 1 drives the gear to push the gear ring, thereby exerting a driving force on the mounting cylinder.

[0012] Preferably, a guide hopper is provided at an opening of the screen drum, and the inner diameter of the guide hopper gradually decreases toward one side. The guide hopper guides concrete particles in the crushing process during use.

[0013] Preferably, the mounting frame is tilted as a whole, and the height of the mounting frame gradually decreases toward the guide bucket end. Because the mounting frame is tilted, the entire device is tilted toward the first guide bucket position, the crushed particles will be directed to a lower position, and the materials discharged after screening will better enter the first guide plate, the second guide plate and the third guide plate.

[0014] Preferably, the inner wall of the screen drum 1 is provided with lifting plates distributed in a circular array, and the inner wall of the lifting plates is provided with grooves. The lifting plates lift the particles that have not passed through the screen drum 1, and then lift the particles to a high place and pour them into the guide groove, and then transport them to the crushing roller through the guide groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The concrete blocks of the present invention are input into the interior of the installation cylinder through an opening on one side of the installation cylinder, and the concrete blocks are squeezed and crushed by relatively rotating crushing rollers. The crushed concrete particles are screened in multiple stages by screen drums one and two. The particle sizes after screening are used for different production processes. The screen drums one and two are placed inside the installation cylinder by sliding and plugging. The mesh specifications inside the screening structure can be replaced. By using different screening structures, the screened concrete particles can be adjusted, thereby improving the flexibility of using the screening structure in the crushing device.
