[0022] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 to Figure 5 The belt conveyor device shown is convenient for movement, comprising a conveying belt 1, with pillars 13 provided at the four corners of the conveying belt 1, and a universal wheel 16 installed at the bottom of the pillars 13, so as to achieve the purpose of convenient movement. A roller 12 is rotatably connected between two corresponding pillars 13, and the conveying belt 1 is sleeved between the two rollers 12, wherein a motor 14 is fixedly connected to one of the pillars 13, and the corresponding roller 12 is fixedly connected to the driving shaft of the motor 14. Specifically, the motor 14 rotates to drive the roller 12 fixedly connected to its driving shaft to rotate, and with the cooperation of the other roller 12, the conveying belt 1 rotates to realize the conveying of materials.

[0024] Considering that the conveyor belt 1 is prone to loosening after long-term use, in order to achieve tensioning of the conveyor belt 1 and improve the conveying efficiency of materials, a U-shaped frame 2 is arranged below the conveyor belt 1, and a first rotating shaft 3 is rotatably connected to the U-shaped frame 2, and a tensioning roller 4 is fixedly connected to the first rotating shaft 3, and the tensioning roller 4 is attached to the inner ring of the conveyor belt 1. When the U-shaped frame 2 moves downward, the tensioning roller 4 can be driven to move downward, so as to achieve tensioning of the conveyor belt 1, achieve stable conveying of materials, and improve the conveying efficiency of materials.

[0025] A transverse plate 15 is fixedly connected between two corresponding pillars 13 , a support plate 20 is fixedly connected between the two transverse plates 15 , an electric push rod 21 is fixedly connected to the support plate 20 , and the U-shaped frame 2 is fixedly connected to the telescopic end of the electric push rod 21 .

[0026] Specifically, when the telescopic end of the electric push rod 21 is controlled to be retracted, the tensioning roller 4 will be driven to move downward through the U-shaped frame 2 to achieve tensioning of the conveyor belt 1; therefore, the conveyor belt 1 will drive the tensioning roller 4 to rotate stably during its rotation.

[0027] Furthermore, a storage battery may be arranged on the transverse plate 15 to supply power to the electric push rod 21 (not shown in the figure).

[0028] Considering that dust and impurities are easily accumulated on the outer ring of the conveyor belt 1 during the material conveying process, in order to clean the impurities, a second rotating shaft 5 is rotatably connected to the U-shaped frame 2, and the second rotating shaft 5 rotates synchronously with the first rotating shaft 3 through a transmission assembly. The transmission assembly includes a first pulley 17, a second pulley 18 and a transmission belt 19. The first pulley 17 is fixedly connected to the first rotating shaft 3, and the second pulley 18 is fixedly connected to the second rotating shaft 5. The first pulley 17 and the second pulley 18 are connected by a transmission belt 19. During the rotation of the conveyor belt 1, the tension roller 4 will be driven to rotate, and with the cooperation of the transmission assembly, the second rotating shaft 5 rotates synchronously. A cylinder 6 is fixedly connected to the second rotating shaft 5, and a square groove 7 is opened on the outer wall of the cylinder 6. The square grooves 7 are arranged in a plurality, and the plurality of square grooves 7 are evenly distributed around the cylinder 6. A round rod 8 is fixedly connected to the inside of the square groove 7, and a rotating block 9 is rotatably connected to both ends of the round rod 8. A scraper 10 for cleaning the outer ring of the conveyor belt 1 is fixedly connected between the two rotating blocks 9.

[0029] Specifically, the conveyor belt 1 will drive the tension roller 4 to rotate during its rotation, and with the cooperation of the transmission assembly, the second rotating shaft 5 will rotate synchronously, so that the cylinder 6 will drive the scraper strip 10 to rotate.

[0030] Reference Figure 4 , the conveyor belt 1 moves from right to left, driving the tension roller 4 to rotate clockwise, so that the cylinder 6 drives the scraper 10 to rotate clockwise. When the scraper 10 fits on the conveyor belt 1, it pushes and scrapes the outer ring of the conveyor belt 1. In the process of continuing to rotate, under the extrusion of the conveyor belt 1, the scraper 10 drives the rotating block 9 to use the round rod 8 as the internal recovery of the axial square groove 7 (at the same Figure 4 The rotating block 9 at the top position does not affect the rotation of the cylinder 6.

[0031] Furthermore, the plurality of scraping strips 10 cooperate to achieve a continuous scraping and cleaning effect.

[0032] By arranging structures such as the U-shaped frame 2, the tensioning roller 4, the cylinder 6 and the scraper strip 10, the conveyor belt 1 is tensioned, the material is stably conveyed, the material conveying efficiency is improved, and the outer ring of the conveyor belt 1 is pushed and scraped to clean.

[0033] In order to reset the scraper strip 10 and other structures, torsion springs 11 are mounted on both ends of the round rod 8, one end of the torsion spring 11 is fixedly connected to the rotating block 9, and one end of the torsion spring 11 is fixedly connected to the inner wall of the square groove 7. During push-scraping cleaning, the reset elastic force of the torsion spring 11 makes the scraper strip 10 fit on the outer ring of the conveyor belt 1, thereby improving the cleaning effect.

[0034] As the cylinder 6 rotates, when the scraper strip 10 is offset from the conveyor belt 1, the rotating block 9 quickly resets and vibrates under the reset force of the torsion spring 11, so that the impurities remaining on the scraper strip 10 fall off, which is convenient for subsequent use.
