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

A kind of sieve plate fastener

Technical field:

The present invention be a kind of sieve plate that is applicable to use on vibratory sieve with sieve nest crossbeam between the fastener that is connected.

Background technology:

Connected mode between existing vibration sieve plate and sieve nest crossbeam is mostly to fix with bolt, and the compass screen surface elasticity after this fixing greatly reduces, and the mesh phenomenon that easily results in blockage, affects screening efficiency.

Summary of the invention:

The object of this invention is to provide a kind of compass screen surface fixing after elasticity large, screening efficiency is high, effectively prevents from stopping up the sieve plate holding structure of mesh phenomenon.

Technical scheme of the present invention completes as follows, a kind of sieve plate fastener, it includes sieve plate and vibrating screen beam, it is characterized in that: in sieve plate both sides, be respectively equipped with the tensioning hook with sieve plate sidewall phase hook, the neck of hook of each tensioning hook slides respectively and is inserted in the jack of a block plate, each seat board is weldingly fixed on respectively on the crossbeam of screen(ing) machine both sides, on each neck of hook, in the outside of seat board, be separately installed with a helical spring, on the neck of hook of each helical spring outer end, be bolted with respectively a clamp nut, on the neck of hook between clamp nut and helical spring, be provided with packing ring.

This sieve plate fastener can make sieve plate fixed, makes again sieve plate have good elasticity, has effectively solved obstruction mesh phenomenon.

Accompanying drawing explanation:

Fig. 1 is structural representation of the present invention.

The specific embodiment:

Describe by reference to the accompanying drawings embodiment in detail, it includes sieve plate 1 and vibrating screen beam 7, in sieve plate both sides, be respectively equipped with the tensioning hook 2 with sieve plate sidewall phase hook, the neck of hook of each tensioning hook slides respectively and is inserted in the jack of a block plate 3, each seat board is weldingly fixed on respectively on the crossbeam of screen(ing) machine both sides, on each neck of hook, in the outside of seat board, be separately installed with a helical spring 4, on the neck of hook of each helical spring outer end, be separately installed with a clamp nut 6, more reliable for what helical spring was compressed, on the neck of hook between clamp nut and helical spring, be provided with packing ring 5.During installation, seat board is welded on vibrating screen beam, then in seat board jack, introduces the neck of hook of tensioning hook, penetrate helical spring and packing ring, then set up nut in neck of hook outside, fastening nut again after tensioning hook and sieve plate are hooked, by sieve plate tensioning.

Claims

1. a sieve plate fastener, it includes sieve plate and vibrating screen beam, it is characterized in that: in sieve plate both sides, be respectively equipped with the tensioning hook with sieve plate sidewall phase hook, the neck of hook of each tensioning hook slides respectively and is inserted in the jack of a block plate, each seat board is weldingly fixed on respectively on the crossbeam of screen(ing) machine both sides, on each neck of hook, in the outside of seat board, be separately installed with a helical spring, on the neck of hook of each helical spring outer end, be bolted with respectively a clamp nut, on the neck of hook between clamp nut and helical spring, be provided with packing ring.
