Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a screen plate fixing device for a vibrating screen for construction waste. Background Technology

[0002] In the process of construction waste disposal, after the aggregate is crushed, it needs to be graded by a vibrating screen. During the operation of the vibrating screen, aggregates smaller than the screen aperture are screened and graded under vibration, and then recycled after impurity removal. For example... Figure 1 The diagram shows the fixed connection between the screen plate and the screen plate support frame in an existing vibrating screen. Strip steel plates are used for clamping, and the strip steel plates are evenly perforated at intervals. Bolts are passed sequentially from bottom to top through the screen plate support frame above the screen frame beam, the screen plate, and the strip steel plate, and then tightened with nuts and anti-loosening washers to clamp the screen plate. A vertical protective angle steel is welded in front of each exposed bolt position on the strip steel plate, with a height exceeding the exposed bolt height, to prevent wear on the bolt shank and nut during aggregate flow, thus preventing failure. The bolts, nuts, and anti-loosening washers are collectively referred to as the bolt assembly. Because construction waste aggregate contains a large amount of strip-shaped, strip-shaped, mesh-shaped, and sheet-shaped plastics, nylon, and fabrics, these lightweight materials will adhere to the vibrating screen during aggregate screening. Figure 1 As the grease accumulates on the protruding bolts and protective angle steel of the screen plate, it will cover the screen plate, causing blockage, reducing the screening area, and lowering the screening efficiency. Operators often need to enter above the screen plate to clean the screen, which affects production efficiency.

[0003] Therefore, it is urgent to revise the existing fixed structure to avoid the accumulation of light materials and clogging of the sieve plate. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects and deficiencies in the existing technology. To this end, this utility model provides a screen plate fixing device for a vibrating screen for construction waste, which can avoid the problem of screen plate blockage caused by light materials sticking to the screen and improve production efficiency.

[0005] To achieve the above objectives, this utility model provides a screen plate fixing device for a vibrating screen for construction waste, including an arched pressure strip with a shell structure. The arched pressure strip has a plurality of mounting sleeves with countersunk holes integrally provided along its length. The bottom of the arched pressure strip abuts against the plane of the screen plate, and the top is provided with a through hole A that matches the mounting sleeve. The mounting sleeve secures the screen plate to the screen frame support frame with bolts, ensuring that there are no protrusions on the outside of the arched pressure strip.

[0006] Furthermore, the arched pressure strip includes a symmetrical arc-shaped portion, and vertical side plate portions are integrally and smoothly provided on both sides of the arc-shaped portion, with the bottom end of the side plate portion abutting against the plane of the sieve plate.

[0007] Further, the bolt assembly comprises an internal hexagonal bolt and, sequentially, a flat washer, an elastic washer and a nut fastened below the screen frame support frame; the internal hexagonal bolt is matched with the countersunk hole of the mounting sleeve, and the head of the internal hexagonal bolt does not exceed the through hole A on the arched pressing strip.

[0008] Further, the mounting sleeve sequentially comprises a sleeve and a U-shaped clamping groove matched with the inner wall of the arched pressing strip from inside to outside; the sleeve and the U-shaped clamping groove are in plane abutment; the U-shaped clamping groove is in plane abutment with the screen plate; the U-shaped clamping groove is provided with a through hole B constituting a counterbore with the sleeve.

[0009] Further, the two sides of the U-shaped clamping groove are matched with the cross-sectional profile of the inner wall of the arched pressing strip and are integrally welded.

[0010] Further, one end of the sleeve is matched with the cross-sectional profile of the inner wall of the arched pressing strip and is integrally welded.

[0011] Further, the inner diameter of the sleeve is the same as the diameter of the through hole A on the arched pressing strip.

[0012] Further, the number of the mounting sleeves is three and they are symmetrically and equidistantly distributed.

[0013] Further, the height of the arched pressing strip is 10mm±0.5mm, and the width is 24mm±0.5mm; the outer wall diameter of the arc-shaped part is 37mm±0.2mm.

[0014] Further, the wall thickness of the arc-shaped part and the side plate part is the same and is 2.4mm±0.1mm.

[0015] Compared with the prior art, the beneficial effects of the utility model are that: by adopting the arched pressing strip and the hidden connection mode of the bolt assembly, the bolt and the protective angle steel and other protrusions above the screen plate are no longer present while ensuring that the screen plate is pressed tightly, the problem of light material hanging on the screen is solved, the occurrence of the situation that the light material blocks the screen plate is reduced, the screening efficiency is improved, the normal working time of the vibrating screen is increased, and the production efficiency is improved.
