TECHNICAL FIELD
[0001] The utility model belongs to the technical field of conveyer belt sweeper, concretely relates to a sweeper scraper. BACKGROUND
[0002] The belt conveyor is the conveying equipment commonly used in mine production, has the advantages such as stable conveying capacity, small energy consumption, low equipment investment cost etc. In mine production, the belt conveyor is usually used to convey ore, ore powder and other materials, and the mud and dust mixed in is easy to be adsorbed on the surface of the conveying belt. In production, the sweeper is usually used to remove the attachments to avoid that the attachments are brought into the gap of the conveyor or the inside of the body to affect the operation.
[0003] The most common sweeper is the scraper type sweeper, that is, the main working part of the sweeper is a scraper directly contacting with the belt. By using the elastic force of the conveying belt and the cooperation of the spring, the scraper is easily pressed on the surface of the belt, so that the scraper has a relatively high cleaning effect, but the hard scraper will generate a large friction with the surface of the conveying belt when scraping the attachments, thereby wearing the conveying belt and reducing its service life.
[0004] The brush type sweeper can reduce the wear of the conveying belt compared with the scraper type, and also has a relatively good cleaning effect. However, the dust is easy to enter the gap between the bristles, and after being blocked by water, the brush will become hard and the elasticity will decrease, and the fitting degree with the conveying belt will decrease. After long-term use, a gap is gradually generated between the brush and the belt, and the cleaning effect is greatly reduced.
[0005] Therefore, it is necessary to provide an improved technical scheme for the above-mentioned problems of the prior art. SUMMARY
[0006] The utility model discloses a sweeper scraper, which has the advantages of good cleaning effect and low wear of the conveying belt, thereby solving the above-mentioned problems of the prior art.
[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0008] A sweeper scraper includes a blade body, a detachable blade connected to the end of the blade body, the blade is made of rubber material, and the distal end of the blade gradually thins, a pressing plate is provided on the blade body or the fixed base, and the pressing plate is used to make the blade fit with the conveying belt.
[0009] Preferably, the distal end of the blade extends 5-15mm out of the pressing plate.
[0010] Preferably, a plurality of blades are provided on the blade body, and the blades are continuous in the width direction of the blade body.
[0011] Preferably, the middle part of the cutter body is provided with a first clamping groove, the first clamping groove is perpendicular to the thickness direction of the cutter body, and the proximal end of the blade is embedded into the cutter body along the first clamping groove.
[0012] Preferably, the middle part of the cutter body is provided with a plurality of parallel second clamping grooves, and the axis direction of the second clamping groove is at a first included angle with the thickness direction of the cutter body.
[0013] Preferably, the first included angle is greater than 70°.
[0014] Preferably, one end or both ends of the second clamping groove are closed.
[0015] Preferably, the end portions of adjacent second clamping grooves overlap.
[0016] Beneficial effects:
[0017] (1) The scraper provided by the present application is made of rubber material, which is softer than the existing hard plastic scraper material, and can avoid applying excessive pressure to the contact surface when contacting the belt, thus achieving cleaning effect without generating excessive friction force to cause belt wear;
[0018] (2) The distal end thickness of the scraper gradually thins, making the part of the scraper contacting the belt softer, which can be deformed greatly under pressure when in use, thus adhering to the surface of the belt and increasing the contact area of the scraper and the belt, which is beneficial to improve the cleaning effect;
[0019] (3) The adjacent parts of the split type scraper are prone to generate gaps if worn, and the inclined cutter body is also adopted, so that the end portions of adjacent scrapers overlap, and the thickness of the overlapping part is greater than that of other parts, which can avoid the problems of generating gaps and missing cleaning after wear.
