Description

Technical Field

[0002] A construction sieve is a tool used to screen and filter construction materials. It is usually made of metal or plastic and has mesh or holes. It is used to screen materials of different particle sizes, such as sand, gravel, cement, etc.

[0003] The Chinese patent application number: CN202321824081.8 discloses a sieve for construction, which has a simple structure and is easy to use. The motor drives the filter screen to move back and forth with the cooperation of the walking wheel, the horizontal plate, the bar block and the plug rod, thereby screening the construction materials. At the same time, by setting two filter screens with different filter diameters, the materials can be screened multiple times at the same time, thereby improving the screening accuracy, improving the screening efficiency, reducing the physical labor of the operator, and bringing convenience to the construction screening;

[0004] However, when the sieve in the comparative patent is used to screen construction materials, the construction materials may stick to the sieve. The sieve in the comparative patent is difficult to self-clean, so the construction materials sticking to the sieve are likely to clog the mesh of the sieve, which may affect the screening efficiency. For this reason, we propose a sieve for construction. Utility Model Content
