It is used for short-distance transportation and loading and unloading of bulk materials or finished items with a single weight of less than 100 kg. For example, application number: 202120765441.6 discloses a mobile belt conveyor with a dust removal structure, including a mounting seat, which is mounted on the upper end surface of an external platform, and the lower end surface of the mounting seat is connected to a universal wheel, a conveyor belt, which is fitted and connected to the outer end surface of the connecting roller installed on both sides, and the outer rear end of the connecting roller A motor is connected, and a convex structure for increasing friction is arranged on the outer surface of the conveyor belt. The support rollers are connected to the inner upper end surface of the conveyor belt at equal intervals, and the front and rear ends of the support rollers are rotatably connected with support plates. The lower end of the limit block is slidably connected to the left upper end of the mounting seat, and the upper end surface of the limit block is provided with a hydraulic rod for adjusting the height. The mobile belt conveyor with a dust removal structure has a dust removal structure, thereby protecting the components, extending the overall service life, and facilitating the adjustment of the height of the conveyor belt, facilitating use, and improving the working efficiency of transportation;

[0003] The mobile belt conveyor disclosed in the above patent has the following deficiencies during use: 1. Since the conveyor belt carries objects for a long time, the conveyor belt often becomes loose, which causes slippage and loosening during transmission and transmission, affecting normal feeding operations. When the conveyor belt becomes loose, in most cases it is necessary to remove one of the two transmission rollers to adjust the distance between the two transmission rollers to adjust the tightness. This operation method is relatively cumbersome and has low adjustment efficiency; 2. When the entire device is moved to the required position through the universal wheel, there is a lack of additional fixed structure, and it relies on the self-locking force of the universal wheel for fixing, which has low stability and the risk of displacement during use, and cannot meet the use requirements. Based on the above situation, we propose a mobile belt conveyor. Utility Model Content

[0031] Working principle: When in use, the entire device can be moved to a desired position through four universal wheels. After moving to the designated location, the four T-shaped fixing anchor rods 5 are rotated forward, and the T-shaped fixing anchor rods 5 are moved downward and inserted into the soil while rotating. The entire device is fixed by the four T-shaped fixing anchor rods 5. The method of fixing the entire device by the T-shaped fixing anchor rods 5 alone can effectively reduce the risk of displacement of the entire device during use;

[0032] During use, the inclination angle of the conveyor belt 103 is first adjusted according to the use needs. When adjusting, the second multi-stage electric telescopic rod 1 is started in the positive direction, and the output shaft of the second multi-stage electric telescopic rod 1 drives the slider 3 to move upward and squeeze the U-shaped plate 2. The squeezing force drives the two mounting plates 101 to rotate upward, and the two mounting plates 101 drive the rotating block to rotate. The two mounting plates 101 also drive the conveyor belt 103 to rotate upward through the two transmission rollers 102, so that the inclination angle of the conveyor belt 103 changes. When the required angle is adjusted according to the use needs, the second multi-stage electric telescopic rod 1 is stopped, thereby realizing the adjustment of the inclination angle of the conveyor belt 103;

[0033] During the conveying process, the driving motor 104 is started, and the output shaft of the driving motor 104 drives the transmission roller 102 on the left to rotate, and the transmission roller 102 on the left drives the transmission roller 102 on the right to rotate through the conveyor belt 103. The two transmission rollers 102 rotate and transmit the conveyor belt 103 at the same time. During the transmission of the conveyor belt 103, the bottom of the conveyor belt 103 rubs against multiple bristles, and under the friction force, the dust attached to the outer side of the conveyor belt 103 is rubbed and cleaned away, and at the same time, the rubbed dust is rubbed to the two sides of the brush plate 11, and the two collection boxes 12 collect the dust, thereby achieving the purpose of frictionally cleaning and collecting the dust on the outer side of the conveyor belt 103 during the conveying process;

[0034] As the conveyor belt 103 is used for a long time, it will become loose. The pressure value of the first multi-stage electric telescopic rod 9 when it is opened and closed is set in advance by the controller 17. When the tightness of the conveyor belt 103 is adjusted initially, the first multi-stage electric telescopic rod 9 is started in the positive direction, and the output shaft of the first multi-stage electric telescopic rod 9 drives the rectangular box 7 to move downward, and the rectangular box 7 slides downward on the two T-shaped guide rods. The rectangular box 7 drives multiple squeezing rollers 8 to squeeze the inner side of the conveyor belt 103 downward. Under the squeezing force, the conveyor belt 103 is deformed and tightened. The rectangular box 7 drives the two squeezing rods 14 and the two balls to move downward through the two pressure sensors 15. When the squeezing rod 14 is restricted by the conveyor belt 103 and cannot continue to move, the rectangular box 7 that continues to move drives the two pressure sensors 15 to compress the two compression springs 16. The pressure sensor 15 detects the squeezing force of the corresponding compression spring 16 and transmits the detected pressure value to the controller 17. When it is detected that the squeezing force reaches the preset value, the controller 17 The controller 17 controls the first multi-stage electric telescopic rod 9 to close, thereby adjusting the tightness of the conveyor belt 103. When the conveyor belt 103 is relaxed again, the compression spring 16 in the compressed state drives the corresponding extrusion rod 14 and the ball to move downward and fit the conveyor belt 103. As a part of the compression spring 16 is released, the extrusion elastic force on the pressure sensor 15 is reduced. When the pressure sensor 15 detects that the extrusion force is lower than the preset value, the controller 17 controls the first multi-stage electric telescopic rod 9 to start forward again, so that the extrusion roller 8 continues to move downward to squeeze and tighten the conveyor belt 103. At the same time, the rectangular box 7 drives the two pressure sensors 15 to compress the compression spring 16 downward. When the pressure sensor 15 detects that the extrusion force reaches the preset value, the controller 17 controls the first multi-stage electric telescopic rod 9 to close, thereby achieving the purpose of automatically adjusting the tightness of the conveyor belt 103 when the conveyor belt 103 is relaxed. There is no need for personnel to disassemble the transmission roller 102 for adjustment, which is convenient for personnel to operate and improves adjustment efficiency.
