Description

Technical Field

[0001] This application relates to the field of conveyor belt cleaning technology, and in particular to a cleaner for clamp-type conveyor belts. Background Technology

[0002] Industrial conveyor belt cleaners are mainly divided into contact type (scraper, brush type) and non-contact type (airflow, vibration). Among them, contact scraper cleaners are widely used due to their simple structure and low cost, such as the traditional single-line fixed cleaner. Structure: The scraper is fixed to the metal bracket by bolts, and the contact angle with the conveyor belt is fixed; Working principle: The scraper relies on its own weight to make the scraper contact the conveyor belt and remove material residue; Limitations: Due to the vibration of the conveyor belt, relying solely on the weight of the cleaner cannot guarantee real-time contact between the scraper and the conveyor belt, resulting in poor cleaning performance.

[0003] However, traditional sweepers have the following technical drawbacks: 1. Low maintenance efficiency: Replacing the scraper requires stopping the machine and disassembling the entire sweeper, which is time-consuming, labor-intensive, and requires high skill from the operators; 2. Poor cleaning effect: The cleaning efficiency is greatly affected by the wear of the scraper. The conveyor belt cannot maintain effective and continuous contact with the scraper, and the residual material on the surface of the conveyor belt cannot be scraped clean. 3. Poor adaptability: Special pressure rollers and other additional devices are required to install different conveyor belt installation shapes (such as arc shape, concave and convex surfaces), resulting in poor adaptability. Utility Model Content

[0004] To address the aforementioned problems, achieve rapid replacement and adaptive adjustment, reduce maintenance costs, improve adaptability, and enhance cleaning performance, this application provides a cleaner for clamp-type conveyor belts.

[0005] The present application provides a cleaning device for a clamp-type conveyor belt, which adopts the following technical solution.

[0006] A cleaner for clamp-type conveyor belts, characterized in that it comprises: The upper cleaner includes an upper scraper, which is mounted above the conveyor belt via an upper mounting mechanism. The upper scraper is arranged at an angle across the conveyor belt and is pressed downward to make the upper scraper contact the upper surface of the conveyor belt. The lower cleaner includes a lower scraper, which is installed below the conveyor belt via a lower mounting mechanism and pressed upward to contact the lower surface of the conveyor belt. There are two lower cleaners spaced apart, and the upper scraper and the two lower scrapers press against each other to flatten the conveyor belt and form a clamping shape.

[0007] By adopting the above technical solution, the upper scraper is installed above the conveyor belt via an upper mounting mechanism, and is distributed at an inclined angle to the conveyor belt's conveying direction. It can press downwards to keep the scraper in contact with the upper surface of the conveyor belt. As the conveyor belt runs, it can scrape away residual material from the upper surface of the conveyor belt, scraping it down the inclined direction to the edge of the conveyor belt until it falls off the conveyor belt. The lower scraper is installed below the conveyor belt via a lower mounting mechanism, and presses upwards to keep the lower scraper in contact with the lower surface of the conveyor belt, directly scraping away material from the lower surface. Furthermore, there are two lower scrapers, which cooperate with the upper scraper to form a clamp around the conveyor belt. The scrapers maintain a certain pressure contact with the conveyor belt, which helps to improve the scraping effect of surface material.

[0008] Optionally, the two ends of the upper scraper are mounted above the conveyor belt via an upper mounting mechanism. The upper mounting mechanism includes an upper channel steel for connecting with the conveyor belt frame. An upper guide shaft is provided in the upper hole of the upper channel steel, and an upper scraper connecting rod is provided in the hole of the upper guide shaft. An upper preload spring is sleeved on the upper guide shaft above the upper scraper connecting rod, and the upper scraper connecting rod is connected to the upper scraper.

[0009] By adopting the above technical solution, the upper pre-tension spring can push the upper scraper connecting rod downward, thereby forcing the upper scraper to maintain contact with the upper surface of the conveyor belt. The upper pre-tension spring provides downward pressure and also plays a buffering pre-tensioning role.

[0010] Optionally, the upper channel steel is connected to the conveyor belt frame via an upper mounting plate. An upper stud is vertically arranged on the upper channel steel, the top of which penetrates the upper mounting plate, and an upper nut is fitted to the top of the upper stud.

[0011] By adopting the above technical solution, the upper stud and the upper nut can be used to control the up and down position of the upper stud by adjusting the upper nut, thereby driving the up and down position of the upper channel steel to move and adjust, thus realizing the adaptive adjustment of the pressure of the upper scraper, and the pressure can be automatically adjusted according to the surface condition of the conveyor belt.

[0012] Optionally, a waist-shaped hole is provided on the upper scraper connecting rod, and the upper scraper connecting rod and the upper scraper are connected by bolts.

[0013] By adopting the above technical solution, the upper scraper connecting rod and the upper scraper are connected by bolts, which makes the assembly method simple, reliable and easy to operate. Furthermore, the setting of the waist-shaped hole on the upper scraper connecting rod facilitates the connection between the upper scraper and the upper scraper connecting rod when using upper scrapers of different lengths, as well as the position adjustment of the upper scraper in both directions, making it more versatile and easier to assemble.

[0014] Optionally, the upper scraper includes an upper blade body and an upper blade pressure rod. The upper blade body is provided with a plurality of upper blade holes spaced apart, and the upper blade body is connected to the upper blade pressure rod by bolts.

[0015] By adopting the above technical solution, the upper blade body remains in contact with the conveyor belt to scrape off materials. As it ages and wears with use, the split structure makes it easy to replace, and the upper blade pressure bar can provide a certain degree of hardness to ensure that a certain pressure is applied to the upper blade body.

[0016] Optionally, the upper scraper is arranged at a 30° angle across the conveyor belt.

[0017] By adopting the above technical solution, the upper scraper is arranged at a 30° angle. As the conveyor belt runs, the upper scraper scrapes off the material on the surface of the conveyor belt, which can push the material to the edge of the conveyor belt and then scrape it off.

[0018] Optionally, the two ends of the lower scraper are installed below the conveyor belt via a lower mounting mechanism. The lower mounting mechanism includes a lower channel steel for connecting with the conveyor belt frame. A lower guide shaft is provided in the upper hole of the lower channel steel. A limit block is provided on the lower guide shaft inside the lower channel steel, and a lower preload spring is sleeved on the lower guide shaft between the bottom of the limit block and the lower channel steel. The top end of the lower guide shaft is connected to the lower scraper connecting rod, and the lower scraper connecting rod is connected to the lower scraper.

[0019] By adopting the above technical solution, the lower pre-tension spring can push the lower scraper connecting rod upward, thereby forcing the lower scraper to maintain contact with the lower surface of the conveyor belt. The lower pre-tension spring provides upward pressure and also plays a buffering pre-tensioning role.

[0020] Optionally, the lower scraper includes a lower blade body and a lower blade pressure rod. The lower blade pressure rod is provided with a connector plate, and the bottom of the lower blade body is provided with a connector groove. The lower blade body cooperates with the connector plate through the connector groove.

[0021] By adopting the above technical solution, the lower blade body remains in contact with the conveyor belt to scrape off materials. As it ages and wears with use, the split structure facilitates replacement. The plug-in connection between the lower scraper and the lower scraper connecting rod is simple, reliable, and easy to replace. Furthermore, the lower blade pressure rod can provide a certain degree of hardness to ensure that a certain pressure is applied to the lower blade body.

[0022] Optionally, the lower scraper connecting rod is inserted into the inner hole of the lower scraper pressure rod for shaft engagement, and the end of the lower scraper pressure rod is threaded with a locking screw. After the locking screw is screwed into the lower scraper pressure rod, the end of the locking screw abuts against the lower scraper connecting rod.

[0023] By adopting the above technical solution, the lower scraper connecting rod and the lower scraper pressure rod hole shaft are matched and can be locked by locking screws to prevent the lower scraper pressure rod from shaking and ensure connection reliability. This connection method is simple and reliable, and can be applied to lower scrapers of different lengths and sizes. They can all be well installed and connected with the lower scraper connecting rod. The operation is simple and the applicability is strong.

[0024] In summary, this application includes at least the following beneficial effects: 1. In this application, the upper scraper is installed above the conveyor belt via an upper mounting mechanism, and is angled towards the conveyor belt's direction of transport. It presses downwards to keep the scraper in contact with the upper surface of the conveyor belt. As the conveyor belt runs, it scrapes away residual material from the upper surface, causing it to fall off the belt along the inclined direction to the edge. The lower scraper is installed below the conveyor belt via a lower mounting mechanism, and presses upwards to keep it in contact with the lower surface of the conveyor belt, directly scraping away material from that surface. Furthermore, there are two lower scrapers, which work in conjunction with the upper scraper to clamp the conveyor belt. This maintains continuous pressure contact between the scraper and the conveyor belt, improving the scraping effect.

[0025] 2. In this application, the upper scraper connecting rod and the upper scraper are connected by bolts, which makes the assembly method simple, reliable and easy to operate. Furthermore, the setting of the waist-shaped hole on the upper scraper connecting rod facilitates the connection between the upper scraper and the upper scraper connecting rod when using upper scrapers of different lengths, as well as the position adjustment of the upper scraper in both directions, making it more versatile and easier to assemble.

[0026] 3. The lower scraper in this application includes a lower scraper body and a lower scraper pressure rod. The separate structure facilitates replacement. The plug-in connection between the lower scraper and the lower scraper connecting rod is simple, reliable, and easy to replace.

[0037] 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.

[0038] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail.

[0039] This application discloses a cleaner for a clamp-type conveyor belt.

[0040] Reference Figures 1 to 8 A cleaner for a clamp-type conveyor belt includes: an upper cleaner 1 and two lower cleaners 2.

[0041] The upper cleaner 1 includes an upper scraper 11. The two ends of the upper scraper 11 are mounted on the conveyor belt 3 via an upper mounting mechanism 12. The upper scraper 11 is pressed downward to make it contact the upper surface of the conveyor belt 3. The upper scraper 11 is arranged at a 30° angle across the conveyor belt 3. As the conveyor belt 3 runs, the upper scraper 11 scrapes the material on the upper surface of the conveyor belt 3. It can push the material to the edge of the conveyor belt and then scrape it off.

[0042] The upper mounting mechanism 12 includes an upper mounting plate 121, an upper channel steel 122, an upper stud 123, an upper guide shaft 125, an upper preload spring 127, and an upper scraper connecting rod 126.

[0043] The upper mounting plate 121 is used to connect with the conveyor belt frame 4. An upper stud 123 is vertically arranged on the upper channel steel 122. The top end of the upper stud 123 passes through the upper mounting plate 121, and the top end of the upper stud 123 is fitted with an upper nut 124. Through the cooperation of the upper stud 123 and the upper nut 124, the upper stud 123 can be controlled by adjusting the upper nut 124, thereby driving the upper channel steel 122 to move and adjust its position. This realizes the adaptive adjustment of the pressure of the upper scraper 11, and can automatically adjust the pressure according to the surface condition of the conveyor belt 3.

[0044] The upper guide shaft 125 is vertically mounted on the upper channel steel 122 and mates with the hole shaft of the upper channel steel 122. An upper scraper connecting rod 126 is mounted in mate with the bottom hole shaft of the upper guide shaft 125. An upper pre-tension spring 127 is sleeved on the upper guide shaft 125 above the upper scraper connecting rod 126. The upper scraper connecting rod 126 is used to connect with the upper scraper 11. With the setting of the upper pre-tension spring 127, the upper scraper connecting rod 126 can be pushed downward, thereby forcing the upper scraper 11 to keep in contact with the upper surface of the conveyor belt 3. The upper pre-tension spring 127 provides downward pressure and also plays a buffering pre-tensioning role.

[0045] An oblong hole 128 is provided on the upper scraper connecting rod 126. The upper scraper connecting rod 126 and the upper scraper pressure rod 112 are connected by bolts. The assembly method is simple, reliable and easy to operate. Furthermore, the oblong hole 128 on the upper scraper connecting rod 126 facilitates the connection between the upper scraper pressure rod 112 and the upper scraper connecting rod 126 when using upper scrapers 11 of different lengths, as well as the position adjustment of the upper scraper 11 at both ends. This makes it more versatile and easier to assemble.

[0046] The upper scraper 11 includes an upper blade body 111 and an upper blade pressure rod 112. The upper blade body 111 has several spaced upper blade holes 113 (threaded holes), and is connected to the upper blade pressure rod 112 by bolts. The upper blade body 111 remains in contact with the conveyor belt 3 to scrape off material. As it ages and wears with use, the split structure facilitates replacement. Furthermore, the upper blade pressure rod 112 provides a certain degree of hardness, ensuring sufficient pressure on the upper blade body 111.

[0047] The lower cleaner 2 includes a lower scraper 21. The two ends of the lower scraper 21 are mounted below the conveyor belt 3 via a lower mounting mechanism 22, and are pressed upwards to make the lower scraper 21 contact the lower surface of the conveyor belt 3. There are two lower cleaners 2 spaced apart. The upper scraper 11 and the two lower scrapers 21 press against each other to flatten the conveyor belt 3 and form a clamping shape.

[0048] The lower mounting mechanism 22 includes a lower channel steel 221, a lower guide shaft 222, a limit block 223, a lower preload spring 224, and a lower scraper connecting rod 225.

[0049] The lower channel steel 221 is used to connect with the conveyor belt frame 4. The lower guide shaft 222 is set on the lower channel steel 221 in the vertical direction and cooperates with the hole shaft of the lower channel steel 221. The lower guide shaft 222 can be a lower stud. A limit block 223 is set on the lower guide shaft 222 inside the lower channel steel 221. The limit block 223 can be a lower nut. A lower preload spring 224 is sleeved on the lower guide shaft 222 between the bottom of the limit block 223 and the lower channel steel 221. Washers are also set between the two ends of the lower preload spring 224 and the limit block 223 and the lower channel steel 221. The top end of the lower guide shaft 222 is connected to the lower scraper connecting rod 225. The lower scraper connecting rod 225 is used to connect with the lower scraper 21. By setting the lower pretension spring 224, the lower scraper connecting rod 225 can be pushed upward, thereby forcing the lower scraper 21 to maintain contact with the lower surface of the conveyor belt 3. The lower pretension spring 224 provides upward pressure and also plays a buffering pretensioning role.

[0050] The lower scraper 21 includes a lower blade body 211 and a lower blade pressure rod 212. A connector plate 213 is mounted on the lower blade pressure rod 212. A connector groove 214 is formed at the bottom of the lower blade body 211. The lower blade body 211 engages with the connector plate 213 via the connector groove 214. A gasket 215 is placed between the connector plate 213 and the connector groove 214. The gasket 215 can be made of adhesive material, which helps to improve installation reliability. The lower blade body 211 remains in contact with the conveyor belt 3 to scrape off materials. As it ages and wears with use, the split structure facilitates replacement. The connector method between the lower blade pressure rod 212 and the lower scraper connecting rod 225 is simple, reliable, and easy to replace. Furthermore, the lower blade pressure rod 212 provides a certain degree of hardness, ensuring sufficient pressure on the lower blade body 211.

[0051] Both the lower scraper connecting rod 225 and the lower scraper pressure rod 212 are square tubes. The lower scraper connecting rod 225 is larger than the lower scraper pressure rod 212. The lower scraper connecting rod 225 is inserted into the lower scraper pressure rod 212, and the end of the lower scraper pressure rod 212 is threaded with a locking screw 226. After the locking screw 226 is screwed into the lower scraper pressure rod 212, the end of the locking screw 226 abuts against the lower scraper connecting rod 225. The lower scraper connecting rod 225 is inserted into the lower scraper pressure rod 212 and can be locked by the locking screw 226 to prevent the lower scraper pressure rod 212 from shaking and ensure the reliability of the connection. This connection method is simple and reliable, and can be applied to lower scrapers 21 of different lengths. They can all be installed and connected well with the lower scraper connecting rod 225. It is easy to operate and has strong applicability.

[0052] In this application, the upper scraper 11 is mounted above the conveyor belt 3 via the upper mounting mechanism 12 and is angled towards the conveying direction of the conveyor belt 3. It can press downwards to keep the scraper in contact with the upper surface of the conveyor belt 3. As the conveyor belt 3 runs, it can scrape away residual material on the upper surface of the conveyor belt 3, which then falls off the conveyor belt 3 along the inclined direction to the edge of the conveyor belt 3 until it falls out of the conveyor belt 3. The lower scraper 21 is mounted below the conveyor belt 3 via the lower mounting mechanism 22 and presses upwards to keep it in contact with the lower surface of the conveyor belt 3, directly scraping away material from the lower surface of the conveyor belt 3. Furthermore, there are two lower scrapers 21; the upper scraper 11 and the two lower scrapers 21 cooperate to form a clamp around the conveyor belt 3, maintaining a certain pressure contact between the scrapers and the conveyor belt 3, which helps to improve the scraping effect of surface material.
