A special-shaped scraper for slime

Abstract

The present invention discloses a special-shaped scraper for slime. A scraper main body is fixed to the bottom end of the support plate. Horizontal mounting holes penetrate through the front and rear parts of the scraper main body in the left-right direction. The bottom of the scraper main body bends to the right, and a reinforcing rib is jointly fixed between the right end and the support plate. A receiving groove is formed in the front-rear direction at the front end of the support plate main body, and movable grooves are formed in the front and rear parts at the right end. The movable grooves communicate with the receiving groove. By dragging the scraper chain, the present invention can use the scraper main body to scrape the slime in the tank body. The curved structure of the scraper main body is more in line with the force application direction, so that the slime can be more easily scraped to the right, thereby reducing the accumulation of slime in the tank body and avoiding the occurrence of chain floating phenomenon. When the scraper moves with the scraper chain, the reciprocating movement of the scraping strip in the movable groove can be indirectly realized by the rolling friction between the contact roller and the tank body.

Description

Technical Field

[0001] The present invention relates to the technical field of coal transportation, and particularly relates to a special-shaped scraper for slime. Background Art

[0002] Scraper conveyor equipment is a commonly used transportation equipment in coal transportation, mainly composed of a head pulley, a tail pulley, an intermediate trough, a scraper chain, a scraper, a driving device and other parts. When the existing scraper conveyor equipment is in use, due to the high viscosity of slime, ordinary scrapers cannot scrape the slime on both sides and the bottom of the scraper trough cleanly, resulting in the accumulation of slime at the bottom of the scraper trough. When the scraper passes through the accumulated coal, it is easy to be lifted by the accumulated coal, resulting in the occurrence of chain floating phenomenon. Moreover, due to the high viscosity of slime, it is easy for slime to accumulate on the surface of the scraper, thus affecting the transportation efficiency. Regarding the problem of chain floating, in the past, methods such as using rake-tooth special-shaped scrapers and installing cleaning devices have been used to solve the occurrence of chain floating problems. However, from the actual effect, although the rake-tooth special-shaped scraper has a better scraping effect than ordinary scrapers and effectively reduces the occurrence of chain floating problems, due to the rake teeth, the accumulated coal agglomerated at the bottom of the trough cannot be completely cleaned. When the rake-tooth special-shaped scraper passes through this accumulated coal, it will still lift the scraper chain, and the chain floating problem still often occurs, and the chain floating problem has not been fundamentally solved, highlighting the deficiencies in the existing technology. Summary of the Invention

[0003] The purpose of the present invention is to provide a special-shaped scraper for slime to solve the above technical problems.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A special-shaped scraper for slime, comprising a support plate, a scraper main body, mounting holes, reinforcing ribs, a receiving groove, a movable groove, a scraping chamfer, a support shaft, a contact roller, a transmission disc, a transmission groove, a protective cover, and a scraping part. The bottom end of the support plate is fixed with the scraper main body. Horizontally arranged mounting holes penetrate through the front and rear parts of the scraper main body in the left-right direction. The bottom of the scraper main body bends to the right, and a reinforcing rib is commonly fixed between the right end and the support plate. A receiving groove is formed in the front-rear direction at the front end of the support plate main body, and movable grooves are formed at the front and rear parts of the right end. The movable grooves are communicated with the receiving groove. Scraping chamfers are processed at both front and rear ends of the movable groove. A vertical support shaft is rotatably connected to the front part of the scraper main body. A contact roller is coaxially fixed to the bottom of the support shaft, and a transmission disc is coaxially fixed to the upper part. A circular transmission groove is provided on the upper part of the transmission disc. A protective cover is fixed to the front part of the right end of the scraper main body. The scraper main body is provided with a scraping part.

[0006] Based on the above technical solution, the scraping part includes a scraping plate, scraping strips, a transmission arm, and a transmission shaft. The scraping plate is slidably connected to the front and back of the receiving groove. The front and rear parts of the right end of the scraping plate are each fixed with a scraping strip. The upper part of the front end of the scraping plate is fixed with a horizontal transmission arm, and the front part of the bottom end of the transmission arm is fixed with a vertical transmission shaft.

[0007] Based on the above technical solution, the scraping strips are inserted into the movable grooves with gaps. The front end of the outer circumferential wall of the contact roller is located in front of the front end of the support plate and the scraping plate body. The transmission groove is inserted into the transmission shaft, and the inner circumferential wall of the transmission groove is in contact and fit with the outer circumferential wall of the transmission shaft. The transmission groove is eccentrically arranged compared to the support shaft. During the rotation of the contact roller, the transmission disk can be driven to rotate through the support shaft. During the rotation of the transmission disk, the scraping plate can be driven to slide back and forth along the receiving groove through the transmission groove and the transmission shaft. During the process of the scraping plate sliding back and forth along the receiving groove, the scraping strips can be driven to slide back and forth in the movable grooves.

[0008] Compared with the prior art, the present invention has the following advantages: By dragging the scraper chain, the present invention can use the scraping plate body to scrape the slime in the trough. The curved structure of the scraping plate body is more in line with the force application direction, so that the slime can be more easily scraped to the right, thereby reducing the accumulation of slime in the trough and avoiding the occurrence of chain floating. When the scraper follows the scraper chain to move, the reciprocating movement of the scraping strip in the movable groove can be indirectly realized by the rolling friction between the contact roller and the trough, so that the slime adhering to the scraping plate body can be scraped, thereby reducing the accumulation of slime on the surface of the scraping plate body.

DETAILED DESCRIPTION OF THE INVENTION

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] As Figures 1-4 shown, a special-shaped coal slime scraper includes a support plate 1, a scraper body 2, mounting holes 3, reinforcing ribs 4, a receiving groove 5, a movable groove 6, a scraping chamfer 7, a support shaft 8, a contact roller 9, a transmission disc 10, a transmission groove 11, a protective cover 12, and a scraping part 13. The bottom end of the support plate 1 is fixed with the scraper body 2. Horizontally arranged mounting holes 3 penetrate through the front and rear parts of the scraper body 2 in the left-right direction. The bottom of the scraper body 2 bends to the right, and a reinforcing rib 4 is fixedly connected between the right end and the support plate 1. A receiving groove 5 is formed in the front-rear direction at the front end of the main body of the support plate 1, and movable grooves 6 are formed at the front and rear parts of the right end. The movable grooves 6 communicate with the receiving groove 5. Scraping chamfers 7 are processed at both the front and rear ends of the movable groove 6. When the movable groove 6 and the scraping strip 15 move relative to each other, the coal slime can be better scraped off by the scraping chamfers 7. A vertical support shaft 8 is rotatably connected to the front part of the scraper body 2. A contact roller 9 is coaxially fixed to the bottom of the support shaft 8, and a transmission disc 10 is coaxially fixed to the upper part. An annular transmission groove 11 is provided on the upper part of the transmission disc 10. A protective cover 12 is fixed to the front part of the right end of the scraper body 2. The protective cover 12 is used to prevent the coal slime from contaminating the contact roller 9 and the transmission disc 10, thereby ensuring the normal rotation of the contact roller 9. The scraper body 2 is provided with a scraping part 13.

[0016] The scraping part 13 includes a scraping plate 14, a scraping strip 15, a transmission arm 16, and a transmission shaft 17. The scraping plate 14 is slidably connected to the receiving groove 5 in the front-rear direction. Scraping strips 15 are respectively fixed to the front and rear parts of the right end of the scraping plate 14. A horizontal transmission arm 16 is fixed to the upper part of the front end of the scraping plate 14. A vertical transmission shaft 17 is fixed to the front part of the bottom end of the transmission arm 16.

[0017] The scraping strip 15 is inserted into the movable groove 6 with a gap. The front end of the outer circumferential wall of the contact roller 9 is located in front of the front ends of the support plate 1 and the scraper body 2. The transmission groove 11 is inserted into the transmission shaft 17. The inner circumferential wall of the transmission groove 11 is in contact and fit with the outer circumferential wall of the transmission shaft 17. The transmission groove 11 is eccentrically arranged relative to the support shaft 8. During the rotation of the contact roller 9, the transmission disc 10 can be driven to rotate through the support shaft 8. During the rotation of the transmission disc 10, the scraping plate 14 can be driven to slide back and forth along the receiving groove 5 through the transmission groove 11 and the transmission shaft 17. During the process of the scraping plate 14 sliding back and forth along the receiving groove 5, the scraping strip 15 can slide back and forth in the movable groove 6.

[0018] Working principle of the present invention: Use this device to replace the original scraper position of the scraper conveyor, that is, fix the scraper body 2 on the scraper chain through the mounting hole 3, and make the right side of the scraper body 2 the running direction of the scraper conveyor, so that the bottom end of the scraper body 2 contacts the bottom end of the inner wall of the trough, and make the outer circumferential wall of the contact roller 9 roll and friction with the front end of the inner wall of the trough. Subsequently, during the operation of the scraper conveyor, the contact roller 9 can be continuously rotated by the rolling friction between the contact roller 9 and the trough, so that the cleaning scraper 14 can be driven to reciprocate back and forth along the receiving groove 5 by the support shaft 8, the transmission disk 10, the transmission groove 11, the transmission shaft 17 and the transmission arm 16. Then, the cleaning strip 15 reciprocates back and forth in the movable groove 6. During the process of the scraper body 2 moving along with the scraper chain, the scraper body 2 can clean the slime at the bottom of the trough, and the reciprocating movement of the cleaning strip 15 in the movable groove 6 can scrape the slime on the right part of the scraper body 2 back and forth, thus preventing the slime from adhering to the right end of the scraper body 2 and accumulating. Moreover, the curved structure of the scraper body 2 is more in line with the force application direction, so that the slime can be more easily scraped to the right, thereby reducing the accumulation of slime in the trough.

[0019] The above is a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principle and spirit of the present invention, the changes, modifications, substitutions and variations made to the embodiments still fall within the protection scope of the present invention.
