Abstract

The utility model discloses a screen plate tightening device. The screen plate tightening device comprises a screen plate and a vibration screen cross beam. Tensioning hooks are arranged on the two sides of the screen plate respectively and are connected with side walls of the screen plate in a hooking mode, a hook handle of each tensioning hook is slidably inserted into an insertion hole of one corresponding seat plate, and the seat plates are fixed to cross beams on the two sides of a screening machine respectively in a welding mode. Each hook handle is provided with a spiral spring outside the corresponding seat plate, the portion, at the outer end of each spiral spring, of the corresponding hook handle is connected with a gland nut in a threaded mode, and gaskets are arranged on the portions, between the gland nuts and the spiral springs, of the hook handles. By means of the screen plate tightening device, the screen plate can be firmly fixed and have good elasticity, and the net hole blockage problem is effectively solved.

Description

A kind of sieve plate fastener

Technical field:

The utility model is the fastener being connected between a kind of sieve plate that is applicable to use on vibratory sieve and sieve nest crossbeam.

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 purpose of this utility model be 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.

The technical solution of the utility model completes as follows, a kind of sieve plate fastener, it includes sieve plate and vibrating screen beam, it is characterized in that: be respectively equipped with the tensioning hook with sieve plate sidewall phase hook in sieve plate both sides, 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, be separately installed with a helical spring in the outside of seat board, 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 utility model.

The specific embodiment:

Describe by reference to the accompanying drawings embodiment in detail, it includes sieve plate 1 and vibrating screen beam 7, be respectively equipped with the tensioning hook 2 with sieve plate sidewall phase hook in sieve plate both sides, 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, be separately installed with a helical spring 4 in the outside of seat board, 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.When 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: be respectively equipped with the tensioning hook with sieve plate sidewall phase hook in sieve plate both sides, 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, be separately installed with a helical spring in the outside of seat board, 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.
