Embodiment Construction

[0008] The embodiment is described in detail in conjunction with the accompanying drawings. It includes a sieve plate 1 and a vibrating screen beam 7. Tensioning hooks 2 hooked to the side walls of the sieve plate are respectively provided on both sides of the sieve plate, and the hook handles of each tensioning hook slide separately. Inserted into the socket of a seat plate 3, each seat plate is welded and fixed on the beams on both sides of the screen machine, and a coil spring 4 is respectively installed on the outside of the seat plate on each hook handle, and the outer end of each coil spring A compression nut 6 is respectively installed on the hook handle, in order to compress the coil spring more reliably, a washer 5 is provided on the hook handle between the compression nut and the coil spring. During installation, the seat plate is welded on the vibrating screen beam, and then the hook handle of the tensioning hook is introduced into the socket of the seat plate, and t...

Abstract

The invention discloses a screen plate fastening device. The screen plate fastening device comprises a screen plate and a vibrating screen cross beam. Tensioning hooks are arranged at the two sides of the screen plate respectively and are hooked to the side walls of the screen plate. A hook handle of each tensioning hook is inserted into an insertion hole of a seat plate in a sliding mode. Each seat plate is welded to and fixed to the cross beam arranged on the two sides of a screening machine. A spiral spring is installed on the portion, outside one corresponding seat plate, of each hook handle. The portion, arranged at the outer end of one corresponding spiral spring, of each hook handle is connected with a gland nut in a threaded mode. A gasket is arranged on the portion, between one corresponding gland nut and one spiral spring, of the hook. By the adoption of the screen plate fastening device, the screen plate can be firmly fixed, the screen plate can have good elasticity, and the problem that meshes are blocked can be effectively solved.

Description

[0001] Technical field: [0002] The invention is a fastening device suitable for the connection between the sieve plate used on the vibrating screen and the cross beam of the sieve body. Background technique: [0003] The connection between the sieve plate of the existing vibrating screen and the beam of the sieve body is mostly fixed by bolts. The elasticity of the screen surface after this fixation is greatly reduced, which is likely to cause blockage of the mesh and affect the screening efficiency. Invention content: [0004] The purpose of the present invention is to provide a sieve plate fixing device with high elasticity after the sieve surface is fixed, high screening efficiency and effective prevention of mesh blockage. [0005] The technical solution of the present invention is accomplished in the following manner. A sieve plate fastening device includes a sieve plate and a vibrating screen beam, and is characterized in that: on both sides of the sieve plate,...
