and the upper end of the fixed clamping piece is detachably arranged on the bulge, and the lower end of the fixed clamping piece is fixedly connected with the cross beam.
As a further technical scheme, the convex part is a spherical head, the left side and the right side of the fixed clamping piece are provided with two clamping plates which are integrally formed, the plate body at the top end of each clamping plate is bent and rewound towards the inner side direction of the clamping plate to form two clamping rings which are opposite to each other, and the spherical head can be inserted into or pulled out of the clamping plates by mutually expanding or contracting the two clamping rings; the inner sides of the two clamping plates form a cavity for accommodating the spherical head.
As the preferred technical scheme, the bottom of the fixed clamping piece is welded with a nut which is used for being in threaded connection with the cross beam in a matching mode.
As an improved technical scheme, a rhombic groove is formed in the protruding part, the fixing clamping piece is provided with a rhombic head and a base, and the rhombic head is inserted into the rhombic groove to connect and fix the screen and the fixing clamping piece; the base is fixedly arranged on the cross beam through bolts.
The invention has the beneficial effects that:
1. the screen is fixed only by the fixing clamping piece without being fixed by a pressing plate and a pressing plate bolt, and the maintenance caused by damage of a pressing strip and a bolt on the screen is avoided;
2. the vibrating screen is simple to assemble and disassemble, the assembling or the disassembling only needs to be carried out by extruding or pulling out the screen, the assembling and the disassembling are simple and rapid, the maintenance time is greatly prolonged, and the production efficiency of the vibrating screen is improved.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention.
Fig. 2 is a schematic structural diagram of embodiment 2 of the present invention.
Description of reference numerals: the screen comprises a screen 1, a spherical head 1-1, a fixed clamping piece 2, a clamping plate 2-1, a clamping ring 2-2, a rhombic head 2-3, a base 2-, a bolt 3 and a cross beam 4.
Detailed Description
The invention will be described in detail below with reference to the following drawings:
example 1: as shown in the attached figure 1, the vibrating screen mesh fixing device comprises a screen mesh 1, a fixing clamping piece 2 and a cross beam 4, wherein the bottom end of the screen mesh 1 protrudes downwards to form a spherical head 1-1, the left side and the right side of the fixing clamping piece 2 (preferably, the fixing clamping piece 2 is made of sheet metal parts and has good elasticity) are integrally made into two clamping plates 2-1, a plate body at the top end of each clamping plate 2-1 is bent and rewound towards the inner side direction of the clamping plate 2-1 to form two clamping rings 2-2 which are opposite to each other, and the spherical head 1-1 is inserted into or pulled out of the clamping rings 2-2 by mutual opening or contraction of the two clamping rings 2; a cavity for accommodating the spherical head 1-1 is formed at the inner sides of the two clamping plates 2-1; and nuts welded at the bottom of the fixed clamping piece 2 are used for being matched with the bolts 3 to be in threaded connection with and fixed to the cross beam 4.
When the screen mesh fixing device is installed, the spherical head 1-1 is extruded downwards with force, the two clamping rings 2-2 are expanded to enter the fixing clamping piece 2, and then the two clamping rings 2-2 are contracted again to clamp the spherical head 1-1, so that the purpose of fixing the screen mesh 1 is achieved; when the screen mesh 1 is maintained and replaced, the spherical head 1-1 can be pulled out from the fixed clamping piece 2 by strong force.
