[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0017] See also Figure 1-2The utility model provides a technical solution: a bulk material flow measurement device for a belt conveyor with an anti-drifting function, comprising a conveyor belt 1 and a laser scanning probe 2. The laser scanning probe 2 is placed directly above the conveyor belt 1 to scan the cross section of the belt conveyor at that location. An adjustable belt conveyor body is provided below the conveyor belt 1. The adjustable belt conveyor body comprises a horizontal transmission roller 6 and a pair of inclined rollers 7. The conveyor belt 1 comprises a bottom surface and inclined surfaces on both sides that are connected to each other. Each of the transmission rollers 6 is respectively fitted with the bottom surface of the conveyor belt 1, and the pair of inclined rollers 7 are respectively fitted with the inclined surfaces on both sides of the conveyor belt 1. By connecting the horizontal transmission roller 6 and the pair of inclined rollers 7 to the motor, and connecting the frequency converter of the motor to the PLC controller through electrical signals, precise control of the transmission speed is achieved.

[0018] In order to facilitate the adjustment of the angle of the inclined surface of the conveyor belt 1, the materials thereon can be scanned by the laser scanning probe 2 in a more gathered posture. The device also includes a base 8, the horizontal transmission roller 6 is installed on the base 8, and a double-end output motor 9 is embedded and installed in the base 8. The output ends of the double-end output motor 9 are respectively installed with screws 10, and the thread directions of the screws 10 on both sides are opposite. Square holes 11 are respectively opened on both sides of the base 8, and square blocks 12 are slidably connected in the square holes 11. The side walls of the square blocks 12 are opened with screw holes 13, and the screw holes 13 cooperate with the screws 10. By turning on the double-end output motor 9 to drive the screws 10 on both sides to rotate, due to the cooperation effect between the screw holes 13 and the screws 10, the square blocks 12 move inward or outward at the same time, so that the angle adjustment plate 14 can be pushed at the same time.

[0019] An angle adjustment plate 14 is installed at the shaft end of the inclined roller 7, so that the angle adjustment plate 14 is rotatably connected to the base 8. A slide groove 15 is provided on the angle adjustment plate 14, and a slide rail 16 is provided in the slide groove 15. The outer end of the square block 12 is rotatably connected to a sliding block 17, and the sliding block 17 is slidably connected to the slide rail 16. At this time, the movable square block 12 can drive the angle adjustment plates 14 on both sides and the inclined rollers 7 thereon to rotate.

[0020] In order to ensure the overall structural stability of the conveyor belt 1 after the angle is adjusted, auxiliary positioning platforms 3 are respectively provided on both sides of the conveyor belt 1, and support wheels 4 are installed on the auxiliary positioning platforms 3 through a position adjustment mechanism. The auxiliary positioning platforms 3 are installed on the ground through support rods 5. The outer wall of the support wheel 4 is provided with a groove, and the groove fits with the edge of the conveyor belt 1, thereby achieving an anti-drifting effect and ensuring the transportation stability of the conveyor belt 1 to prevent the material from overturning.

[0022] Working principle: When in use, the conveyor belt 1 continuously transfers materials passing directly under the laser scanning probe 2. In order to facilitate the adjustment of the conveying speed of the belt conveyor, it is necessary to scan the actual carrying capacity of the conveyor belt 1, and adjust the speed of the conveyor belt 1 after judgment to increase the transmission efficiency.

[0023] The rotating inclined roller 7 will support the inclined edge of the conveyor belt 1, thereby changing its inclination angle, so that the materials thereon can pass through the scanning of the laser scanning probe 2 in a more gathered posture, thereby cooperating with the subsequent belt conveyor speed transportation adjustment.
