Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a construction waste crushing device for building construction. Background Technology

[0002] With the development of construction waste crushing equipment, more and more such equipment is being used on construction sites for crushing stone, construction waste, and resource recycling. Among these applications, the maintenance of construction waste crushing equipment has always been a time-consuming and labor-intensive issue. To improve the efficiency of the crushing equipment and save on maintenance time and costs, a construction waste crushing device that is easy to disassemble and maintain has been designed.

[0003] Existing hammer-type construction waste crushing devices typically use single-phase integrated bidirectional hammers for crushing. While their structure is simple, the bidirectional hammers wear out quickly, necessitating replacement. Replacing bidirectional hammers usually requires a significant amount of time and manpower; furthermore, the cost of bidirectional hammers is high, resulting in a certain degree of economic loss.

[0004] Existing hammer mill construction waste crushing devices suffer from a significant problem: the unidirectional bidirectional hammers experience substantial wear and tear, and generate considerable noise and vibration, leading to reduced crusher efficiency. Furthermore, the traditional bidirectional hammer structure is simple and cannot be replaced promptly, greatly increasing the operating costs and reducing the efficiency of the hammer crusher. Therefore, there is an urgent need for a hammer mill construction waste crushing device that allows for easy replacement of bidirectional hammers and saves costs. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a construction waste crushing device for construction, comprising a base, a support fixedly connected to the top of the base, a lower shell fixedly connected to the top of the support, an upper shell fixedly connected to the top of the lower shell, a coupling fixedly connected to the bottom of the upper shell and the top of the lower shell, an inlet opening on one side of the upper shell, and a bead lock structure provided inside the upper shell and the lower shell.

[0007] The bead lock structure includes an unlocking structure, which has a spring inside. One end of the spring is fixedly connected to the unlocking structure, and the other end of the spring is fixedly connected to the lock cylinder. The lock cylinder has double beads on both sides, and a locking groove is opened on one side of the double beads. A ball bearing is rotatably connected to the bottom of the lock cylinder.

[0014] As a further description of the above technical solution:

[0015] The hammer handle has a mounting hole at the bottom, and the lock cylinder is rotatably connected inside the mounting hole.

[0016] As a further description of the above technical solution:

[0017] A bidirectional hammer head is fixedly connected to the outer wall of the hammer handle. A second mounting hole is provided at the bottom of the bidirectional hammer head, and a lock cylinder is fixedly and rotatably connected to the second mounting hole.

[0018] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the hammer head and hammer handle are first fixedly connected together by a double-ball lock structure, achieving a separate hammer head that facilitates disassembly and replacement. This solves the problem of time and cost associated with replacing damaged mechanical hammer heads, greatly improving the efficiency of mechanical work and reducing the time and labor costs of subsequent hammer head repairs.

[0024] 2. In this invention, a honeycomb sandwich layer is connected between the two main shaft structures, achieving sound insulation and vibration reduction.
