Technical Field

[0002] Scraper conveyor is a kind of material conveying equipment widely used in industrial fields. Scraper conveyor conveys materials by chain-driven scrapers. With the development of society, scraper conveyors that can convey materials at right angles have been put into use in large quantities.

[0003] Prior art includes an invention with publication number CN116513715B, which discloses a space double-chain right-angle turning assembly for a scraper conveyor, which includes an upper body, a lower body, a scraper and a chain, wherein the upper body and the lower body are symmetrically arranged in the vertical direction, the upper body includes a bottom plate and side plates on both sides thereof, the scraper includes a first scraper, a connecting plate and a second scraper hinged in sequence, and the first scraper rotates relative to the connecting plate around the direction of travel of the chain, the second scraper rotates relative to the connecting plate around a direction perpendicular to the direction of travel of the chain, and a corner curved surface is arranged between the bottom plate and the inner side plate at the corner position. The present invention can realize the material transportation of a medium double-chain right-angle scraper conveyor, enhance the carrying capacity of the scraper conveyor, enhance the tensile performance of the conveyor, reduce the friction resistance of the chain, and can better meet the needs of high-strength and large-capacity material transportation.

[0004] At present, most of the existing scraper conveyors use split scrapers to scrape materials, and at the same time, the scrapers are restricted by two slides. In actual use, the scrapers are prone to detach from the slides at the corners. At the same time, since there is a corner curved surface on the inside of the corner, most of the materials are pushed to the outside, which easily causes the materials to accumulate on the outside. At the same time, it is difficult for the scraper to transport the materials on the outside, which affects the production efficiency of the equipment and is not conducive to the normal use of the conveyor. Improvements are needed in this regard. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that most scraper conveyors in the prior art use split scrapers to scrape materials, and at the same time restrict the scraper by two slides. In actual use, the scraper is prone to detach from the slide at the corner. At the same time, since a corner curved surface is provided on the inner side of the corner, most of the material is pushed to the outside, which easily causes the material to accumulate on the outside. At the same time, it is difficult for the scraper to transport the material on the outside, which affects the production efficiency of the equipment and is not conducive to the normal use of the conveyor. A scraper conveyor spatial double-chain right-angle turn component is proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a scraper conveyor space double-chain right-angle turning component, including a frame, a material guide device is arranged on the surface of the frame, the material guide device includes a material guide trough and a scraper plate, the material guide trough is opened on the surface of the frame, the scraper plate is located in the material guide trough, the inner wall of the material guide trough is fixedly connected with a positioning guide rail, the surface of the scraper plate is provided with a positioning groove, the positioning guide rail is inserted in the positioning groove, the surface of the scraper plate is provided with two symmetrically arranged positioning holes, the two positioning holes are sequentially inserted with a first iron chain and a second iron chain, an inclined groove is arranged at the corner of the material guide trough, a protective device is arranged on the surface of the frame, and a guide assembly is arranged on the surface of the frame. In this scheme, the scraper conveyor realizes right-angle conveying of materials, and adopts an integrated scraper plate to reduce the situation that the scraper plate is detached during use, ensuring the normal operation of the equipment, and at the same time adopts a concave way to design the inclined groove, effectively stacking the materials on the inner side of the corner of the frame, ensuring that the equipment can stably convey the materials, and improving the working efficiency and reliability of the scraper conveyor.

[0007] Preferably, the inner walls of the two positioning holes are fixedly connected to limit frames, and the two limit frames are respectively inserted into the first iron chain and the second iron chain.

[0009] Preferably, the upper end of the positioning guide rail is cylindrical, and the positioning groove is adapted to the positioning guide rail. When the scraper conveyor is running, the scraper plate moves along the guide trough driven by the first iron chain and the second iron chain, and transports the material from one direction to the right-angle turn.

The slider slides with the inner wall of the slide groove to effectively guide the displacement of the protective baffle. The scraper conveyor in this solution realizes right-angle material transportation and adopts an integrated scraper plate to reduce the possibility of the scraper plate detaching during use, thereby ensuring the normal operation of the equipment. At the same time, the inclined groove is designed in a concave manner to effectively accumulate the material on the inner side of the corner of the frame, thereby ensuring that the equipment can stably transport the material, thereby improving the working efficiency and reliability of the scraper conveyor.

The inclined groove opened at the corner of the guide trough can make the material flow more smoothly when turning, reducing the possibility of material accumulation and blockage. The scraper conveyor in this solution realizes right-angle material conveying and adopts an integrated scraper plate to reduce the possibility of the scraper plate detaching during use, ensuring the normal operation of the equipment. At the same time, the inclined groove is designed in a concave manner to effectively accumulate the material on the inner side of the corner of the frame, ensuring that the equipment can stably convey the material, thereby improving the working efficiency and reliability of the scraper conveyor.

[0018] 2. In the present invention, when it is necessary to protect the conveyed material, the control motor is started, and its driving end drives the screw to rotate.
