Description

Technical Field

[0001] This utility model belongs to the field of conveyor belt cleaning technology, and in particular relates to a mineral processing conveyor belt cleaner. Background Technology

[0002] Mineral processing conveyor belts are core equipment in mining transportation systems, capable of continuously and efficiently transporting materials such as coal and ore. They are widely used in open-pit mining and underground transportation. However, during transportation, materials easily adhere to or spill onto the surface of the conveyor belt. If not cleaned in time, this will not only waste materials but also cause the conveyor belt to run off-track, wear to increase, and even cause equipment failure, affecting production efficiency and increasing maintenance costs. Therefore, it is necessary to use a cleaner to remove residual materials in a timely manner to ensure the normal operation of the mineral processing conveyor belt.

[0003] Chinese patent application (or patent) with publication number CN211337721U discloses a conveyor belt cleaner, including two supports arranged at left and right intervals for fixing to a conveyor. A top rod is rotatably mounted on each support, and a scraper assembly is mounted on the top rod. The scraper has slots on both the front and rear sides of its lower part. A slot is provided on the upper side of a scraper mounting frame for inserting the scraper along the length of the top rod. The side walls of the slot have protrusions that engage with the slots. The bottom of the scraper mounting frame is fixed to the top rod. Support arms are provided on the top rod on the left and right sides of the scraper mounting frame. Each support arm includes a sleeve portion that assembles with the top rod and a slanted arm. A spring seat is provided at the end of the slanted arm. A hinge shaft is provided on the support, and a pre-tensioning rod is hinged to the hinge shaft. The other end of the pre-tensioning rod extends into the spring seat, and a locking nut is provided at the end of the pre-tensioning rod, compressing the spring. This cleaner allows the scraper to be in an optimal working position, is adjustable, and improves the scraping effect compared to existing technologies.

[0004] The above-mentioned device cleans the conveyor belt by scraping it with a scraper. However, in actual operation, the effect of relying solely on a scraper is limited, and debris is still easily left on the surface of the conveyor belt, affecting the subsequent operation and efficiency of the equipment.

[0005] To address these issues, we provide a mineral processing conveyor belt cleaner. Utility Model Content

A pulling spring 208 is fixedly connected between the rotating blocks 207 and the corresponding pulling arm 206. The roller brush 203 is driven to rotate in the opposite direction to the conveyor belt by the drive motor 205, which can clean the residue on the conveyor belt. The pulling spring 208 drives one end of the pulling arm 206, which can drive the first rotating shaft 201 to rotate, thereby keeping the roller brush 203 in contact with the conveyor belt and ensuring the cleaning effect.

[0033] The scraper assembly 300 includes a second rotating shaft 301 rotatably connected inside the mounting frame 100. Two sliding sleeves 302 are fixedly connected to the outside of the second rotating shaft 301. A sliding frame 303 is movably sleeved inside the two sliding sleeves 302. A scraper 304 is fixedly connected to the outside of the sliding frame 303.

By having the scraper 304 adhere to the surface of the conveyor belt, debris attached to the outside of the conveyor belt can be cleaned, thereby improving the cleaning effect of the conveyor belt.

[0034] The rinsing assembly 500 includes a horizontal tube 501 fixedly connected inside the mounting bracket 100. Multiple nozzles 502 are equidistantly installed on the outside of the horizontal tube 501 along the axis. Clean water is sprayed onto the conveyor belt through the multiple nozzles 502, thereby further improving the cleaning effect of the conveyor belt.

[0035] Specifically, each of the two mounting shafts 204 has a mounting port 204a at one end opposite to the other. Both ends of the roller brush 203 are fixedly connected to mounting blocks 203a that are compatible with the mounting ports 204a. The mounting blocks 203a are connected to the mounting shafts 204 by bolts. The roller brush 203 can be easily removed by removing the bolts.

[0036] A push spring 305 is movably sleeved inside the sliding sleeve 302, and the sliding frame 303 is located on top of the push spring 305. The push spring 305 pushes the sliding frame 303 to slide upward along the sliding sleeve 302, thereby making the scraper 304 fit against the surface of the conveyor belt, thus improving the cleaning effect of the conveyor belt.

[0037] The scraper 304 includes a plate 304a fixedly connected to the outside of the sliding frame 303 and a scraper head 304b that is in contact with the conveyor belt. A T-shaped groove is provided on the top of the plate 304a, and a T-shaped strip that matches the T-shaped groove is fixedly connected to the bottom of the scraper head 304b.

[0038] The operation process of this embodiment is as follows: When it is necessary to clean the conveyor belt, firstly, by pulling the spring 208, one end of the pulling arm 206 is driven, which can drive the first rotating shaft 201 to rotate, thereby keeping the roller brush 203 in contact with the conveyor belt. Then, by starting the drive motor 205, the roller brush 203 is driven to rotate in the opposite direction to the conveyor belt, thereby performing preliminary cleaning of the conveyor belt. Then, by introducing clean water into the horizontal pipe 501, the clean water is sprayed onto the conveyor belt through multiple nozzles 502, thereby rinsing the conveyor belt. Then, by pushing the spring 305, the sliding frame 303 is pushed to slide upward along the sliding sleeve 302, thereby making the scraper 304 in contact with the surface of the conveyor belt, thereby further cleaning the conveyor belt. Example 2

[0039] Please see Figure 4 and Figure 6 Based on the first specific embodiment, the angle adjustment component 400 includes a screw 401 fixedly connected to one end of the second rotating shaft 301 and a concave chuck 402 fixedly connected to one side of the mounting bracket 100.

A fastening nut 404 is threaded onto the outside of the screw 401. The convex chuck 403 is located between the fastening nut 404 and the concave chuck 402. By rotating the scraper 304 and tightening the fastening nut 404, the convex chuck 403 and the concave chuck 402 are engaged, thereby fixing the angle of the scraper 304.

[0040] Specifically, a dial 405 is fixedly connected to one side of the mounting bracket 100, and a screw 401 is located at the center of the dial 405. An indicator 403a that is compatible with the dial 405 is fixedly connected to the outer edge of the convex chuck 403.
