Description

Technical Field

[0001] This utility model relates to the field of conveyor scraper technology, specifically an integrated eave-shaped reversible scraper for guiding materials. Background Technology

[0002] The conveyor scraper is a key component of belt or scraper conveyors. It is mainly used to remove materials and impurities adhering to the conveyor belt, ensuring the efficient and stable operation of the equipment. The scraper removes materials, dust, moisture and other impurities from the surface and gaps of the conveyor belt through physical friction and scraping principles, preventing equipment failure or safety hazards caused by accumulation.

[0003] In the current market, sweeper scrapers are not equipped with corresponding devices to prevent material accumulation. Manual cleaning of accumulated material poses significant safety hazards, while lever-type mechanical cleaning of accumulated material is prone to malfunctions, has high manufacturing costs, and is difficult to maintain. Therefore, an integrated eaves-shaped reversible scraper is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an integrated eave-shaped reversible scraper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated eave-shaped reversible scraper, including a scraper body, an eave-shaped plate connected to the scraper body, an elastic block provided on the side or inside of the eave-shaped plate, a slot provided at the bottom of the elastic block, a locking block engaged in the slot, the locking block being connected to the blade holder, and the locking block being connected to the elastic block.

[0006] As a further improvement, the scraper body, the eaves plate, and the elastic block are integrally formed.

[0007] As a further improvement, the card block and the tool holder are either welded together or are integrally formed.

[0008] As a further improvement, the locking block is installed by bolts to the elastic block.

[0009] As a further improvement, the two ends of the card block extend to the outside of the elastic block and are provided with screw holes.

[0010] As a further improvement, at least two scraper bodies are provided, arranged in the same row, and adjacent scraper bodies are fixedly installed by screws passing through the screw holes of the clip.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By incorporating an eaves plate and a scraper body, the inclined structure of the eaves plate allows scraped material to slide quickly down the eaves surface and naturally break off and drip at the eaves corners due to gravity. This avoids the long-term accumulation of material on the blade holder or frame surface caused by traditional scrapers. The scraper body can be made of rubber, metal, or non-metallic materials, selected according to the material characteristics, reducing the probability of material, especially sticky materials, adhering to the blade head, further reducing material accumulation and secondary cleaning costs. With the addition of slots and blocks, the scraper body can be quickly disassembled and rotated 180° through the engaging structure of the slots and blocks, achieving reversible use. When one side of the working surface wears down, flipping it over allows the other side to be used, doubling the scraper's service life, reducing replacement frequency and consumable costs. The scraper assembly can be installed and replaced without complicated tools, significantly shortening maintenance time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 and 2 The integrated reversible scraper with an eaves-shaped guide includes a scraper body 1, an eaves-shaped plate 2 connected to the scraper body 1, and an elastic block 3 provided on the side or inside of the eaves-shaped plate 2. A slot 7 is provided at the bottom of the elastic block 3, and a locking block 5 is engaged in the slot 7. The locking block 5 is connected to the blade holder 6 and the elastic block 3. The eaves-shaped plate 2 has an inclined structure, and the scraped material can slide quickly down the eaves surface and naturally break and drip at the eaves corner due to gravity. This avoids the long-term accumulation of material on the blade holder 6 or the frame surface due to the accumulation of material in traditional scrapers. Furthermore, the scraper body 1 can be made of rubber, metal or non-metal materials according to the characteristics of the material, reducing the probability of material, especially sticky material, adhering to the blade head, further reducing material accumulation and secondary cleaning costs.

[0021] The scraper body 1, the eaves plate 2, and the elastic block 3 are integrally formed, and the scraper body 1 and the eaves plate 2 are symmetrically arranged about the center vertical line of the elastic block 3. The bottom end of the elastic block 3 is provided with a slot 7. By setting the slot 7 and the locking block 5, the scraper body 1 can be quickly disassembled and rotated 180° through the locking structure of the slot 7 and the locking block 5, realizing reversible use. When one side of the working surface is worn, it can be flipped to use the other side, which doubles the service life of the scraper and reduces the replacement frequency and consumable costs. The locking block 5 is locked in the slot 4, and the bottom end of the locking block 5 is fixedly connected to the blade holder 6. Through holes can be pre-set on both sides of the blade holder 6 for easy installation.

[0022] This device adopts a dual fixing mode of "clamping positioning + lateral locking". During installation, the one-piece molded scraper assembly, including the scraper body 1, the eave plate 2 and the elastic block 3, is placed vertically downwards, so that the bottom slot 4 is fitted onto the locking block 5 of the blade holder 6. The locking block 5 restricts the displacement of the scraper assembly in the front-back and left-right directions, and firmly locks the scraper assembly in the current position to prevent the scraper from loosening due to equipment vibration.

[0023] The scraper body 1 and the eaves plate 2 adopt a streamlined transition, and the two sides of the eaves plate 2 are designed with large-angle slopes, similar to the eaves structure. When the conveyor belt is running, the scraped material flows down along the scraper body 1 to the surface of the eaves plate 2. Due to the large slope and smooth surface of the eaves plate 2, the material cannot stay and will accelerate down under the action of gravity. When the material flows to the corner of the bottom of the eaves plate 2, due to the suspension below, the width of the elastic block 3 is less than the maximum width of the eaves plate 2, forming a "dripping eaves" effect. The material will break naturally at this point and drip directly to the collection point below, thereby physically blocking the path of the material to the knife holder 6 or the clamping mechanism, realizing the maintenance-free anti-accumulation function.

[0024] The scraper body 1, the eaves plate 2, and the elastic block 3 of this invention are completely symmetrical about the central vertical axis in cross-section. When the working surface of one side of the scraper body 1 becomes worn due to long-term friction, resulting in a decrease in cleaning effect, the operator only needs to rotate the handle 10 in the opposite direction to loosen the clamping plate 11, pull the scraper assembly upwards, rotate it 180 degrees horizontally, and then align the slot 7 with the locking block 5 again, press it down, and lock it. At this time, the intact working surface that was originally located on the rear side is moved to the front side to contact the conveyor belt, and it can be used again. This design doubles the service life of the scraper without the need to replace new parts.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
