[0002] In metallurgical production, conveying equipment (such as belt conveyors) is often used to transport and handle metallurgical materials (raw materials or waste generated during metallurgical production) to facilitate production. After long-term use, belt conveyors will carry material residue on the belt. To prevent the material residue from damaging the belt and to ensure the normal operation of the belt conveyor, it is necessary to clean the material residue on the belt conveyor in a timely manner.

[0003] In existing technologies, a scraper is typically installed below or at the front of the material discharge end of a belt conveyor. This scraper remains stationary.

[0030] Embodiment one

[0031] The embodiment provides a belt cleaning device, as shown in Figure 1 Can more thoroughly scrape the belt, ensure the cleaning effect of the belt, and be beneficial to prolong the service life of the belt.

[0032] As shown in Figure 1 The belt cleaning device comprises a material receiving piece 1, a material scraping unit 2 and a driving unit 3.The material receiving piece 1 is arranged below the belt of the belt conveyor, and the material receiving piece 1 is used for receiving materials.The material scraping unit 2 comprises a material scraping vehicle 21 and a material scraping piece 22.The material scraping vehicle 21 is movably arranged on the material receiving piece 1 in the horizontal direction and is located below the belt.The material scraping piece 22 is arranged on the material scraping vehicle 21 at an angle with the movement direction of the belt and is used for scraping the belt.The driving unit 3 is arranged below the belt, the driving unit 3 is in transmission connection with the material scraping vehicle 21, and the driving unit 3 is used for driving the material scraping vehicle 21 to move reciprocatingly in the horizontal direction.

[0033] When the belt conveyor is used to transport materials, the belt carries the residues of the materials, and the scraper 21 is driven by the driving unit 3 to move reciprocatingly in the horizontal direction. When the moving direction of the scraper 21 is opposite to the moving direction of the belt, that is, the scraper 21 drives the scraping member 22 to move towards the belt, the scraping member 22 scrapes the surface of the belt, thereby cleaning the residues of the materials on the surface of the belt. By setting the scraping member 22 to move towards the belt, the scraping force of the scraping member 22 on the belt can be increased, thereby improving the cleaning effect. Moreover, the scraper 21 drives the scraping member 22 to move reciprocatingly, which can scrape the belt for multiple times, thereby thoroughly scraping the belt and ensuring the cleaning effect on the belt, thereby being beneficial to prolong the service life of the belt. In addition, the residues of the materials scraped by the reciprocating movement of the scraper 21 are received and collected by the receiving member 1. When the belt is cleaned, the residues of the materials collected by the receiving member 1 can be centrally treated, thereby avoiding the residues of the materials from randomly falling to pollute the environment.

[0034] Optionally, as shown in Figure 1 the driving unit 3 comprises a transmission assembly 31 and a driving mechanism 32. The transmission assembly 31 is connected with the scraper 21, and the housing of the driving mechanism 32 is arranged on one side of the belt conveyor. The output end of the driving mechanism 32 is in transmission connection with the scraper 21 through the transmission assembly 31, and is used to drive the scraper 21 to move reciprocatingly in the horizontal direction. When the belt needs to be cleaned, the driving mechanism 32 is started, and the driving mechanism 32 drives the scraper 21 to move reciprocatingly in the horizontal direction through the transmission assembly 31, thereby enabling the scraping member 22 to repeatedly and multiple times scrape the surface of the belt, and realizing the cleaning of the belt. The structure is simple and convenient to operate.

[0035] Optionally, as shown in Figure 1 the transmission assembly 31 comprises a connecting piece 311, two first rotating shafts 312 and two second rotating shafts 313. The two ends of the connecting piece 311 are respectively connected with the front and rear ends of the scraper 21. The two first rotating shafts 312 are arranged on the receiving member 1 in the conveying direction of the belt conveyor, and the two second rotating shafts 313 are arranged on the side away from the belt conveyor of the first rotating shaft 312, and the two second rotating shafts 313 and the two first rotating shafts 312 are in one-to-one opposition. Therefore, the two second rotating shafts 313 and the two first rotating shafts 312 are arranged in a rectangular shape, wherein the two second rotating shafts 313 are located below the belt, and the two first rotating shafts 312 are located outside the belt. The connecting piece 311 is arranged around the two first rotating shafts 312, the two second rotating shafts 313 and the output end of the driving mechanism 32, and the driving mechanism 32 is used to drive the connecting piece 311 to rotate forward or reversely around the two first rotating shafts 312 and the two second rotating shafts 313.

[0036] When belt cleaning is required, the drive mechanism 32 is activated, causing the connecting piece 311 to rotate forward around the two first rotating shafts 312 and two second rotating shafts 313. Since the connecting piece 311 is connected to the scraper trolley 21, its rotation causes the scraper trolley 21 to move horizontally. During this process, the scraper 22 scrapes the belt surface. Then, the drive mechanism 32 is controlled to rotate the connecting piece 311 in the opposite direction around the two first rotating shafts 312 and two second rotating shafts 313, resetting the scraper trolley 21. It then rotates forward again, allowing the scraper 22 to scrape the belt once more. By controlling the drive mechanism 32 to rotate the connecting piece 311 in both directions, the scraper trolley 21 can reciprocate horizontally, enabling the scraper 22 to scrape the belt surface multiple times, ensuring a thorough cleaning and effective cleaning.

[0037] For example, the drive mechanism 32 includes a rotary motor, and the connector 311 includes a wire rope.

[0038] Optionally, such as Figure 1 As shown, the drive unit 3 also includes a first limit switch 33 and a second limit switch 34. The first limit switch 33 and the second limit switch 34 are spaced apart on the receiving component 1 along the conveying direction of the belt conveyor, and both are electrically connected to the drive mechanism 32. The scraper trolley 21 has a first contact state and a second contact state. In the first contact state, the scraper trolley 21 contacts the first limit switch 33, causing the first limit switch 33 to control the rotary motor to rotate in the forward direction. In the second contact state, the scraper trolley 21 contacts the second limit switch 34, causing the second limit switch 34 to control the rotary motor to rotate in the reverse direction.

[0039] When cleaning the belt, firstly, the rotary motor is controlled to drive the connecting piece 311 to rotate forward, causing the connecting piece 311 to drive the scraper 21 to move horizontally on the receiving piece 1. During this process, the scraper 22 will scrape the surface of the belt until the scraper 21 contacts the second limit switch 34. At this time, the scraper 21 has a second contact state. The second limit switch 34 will control the rotary motor to rotate in the reverse direction, thereby causing the rotary motor to drive the connecting piece 311 to rotate in the reverse direction. The connecting piece 311 will drive the scraper 21 to move in the reverse direction horizontally, that is, the scraper 21 will reset until the scraper 21 contacts the first limit switch 33. At this time, the scraper 21 has a first contact state. The first limit switch 33 will control the rotary motor to rotate forward again, thereby causing the rotary motor to drive the connecting piece 311 to rotate forward again, causing the connecting piece 311 to drive the scraper 21 to move horizontally on the receiving piece 1 again, so that the scraper 22 can repeatedly scrape the surface of the belt.

[0040] In other embodiments, the transmission assembly 31 comprises a connecting rod. The housing of the driving mechanism 32 is arranged at one side of the belt conveyor, and the output end of the driving mechanism 32 is retractable relative to the housing of the driving mechanism 32. The output end of the driving mechanism 32 is in transmission connection with the connecting rod, and the driving mechanism 32 is configured to drive the connecting rod to move in the horizontal direction. The end of the connecting rod away from the driving mechanism 32 is connected with the scraper 21. When cleaning the belt, the driving mechanism 32 is started to make the output end of the driving mechanism 32 retractable, so that the driving mechanism 32 drives the scraper 21 to reciprocate in the horizontal direction through the connecting rod, and then the scraper 21 drives the scraping member 22 to repeatedly sweep the surface of the belt for multiple times, thereby achieving more thorough cleaning of the belt.

[0041] Exemplarily, the driving mechanism 32 comprises a telescopic electric cylinder or a telescopic pneumatic cylinder, etc.

[0042] Optionally, the scraper 21 comprises a vehicle body 211 and a plurality of first walking wheels.

The first walking wheels are in rolling cooperation with the upper surface of the scraping member 1, and the scraping member 22 is arranged at the upper end of the vehicle body 211. By arranging the plurality of first walking wheels at the bottom of the vehicle body 211, the frictional resistance between the vehicle body 211 and the scraping member 1 can be reduced, the moving efficiency of the vehicle body 211 can be improved, the vehicle body 211 can be more stable and reliable when moving, and the safety is higher.

[0043] Exemplarily, 2 or 4 or 6 first walking wheels are arranged. In other embodiments, other numbers of first walking wheels can also be arranged according to actual needs, which are not limited herein.

[0044] Optionally, as shown in Figure 1 the scraper 21 further comprises a plurality of second walking wheels 212.
