[0003] The existing speed measurement mechanism of coal belt conveyor mostly adopts relatively simple mechanical structure and technical principle.Commonly used method is to install contact type speed measurement roller directly beside the belt, the roller is driven to rotate by the friction force between roller and belt surface, and then the rotation of roller is transmitted to speed sensor by simple gear transmission or direct connection, to obtain the running speed of belt.Some also use the principle based on photoelectric induction, set reflective strip or light shield on the edge of belt, and use photoelectric sensor to detect the change of light to calculate the speed of belt.

[0004] When the angle of speed measurement roller or photoelectric sensor needs to be changed to adapt to the running state of belt under different working conditions, manual direct bending of relevant components is usually used.This method is difficult to realize accurate positioning in actual operation, because the operator adjusts only by experience and hand feeling, and it is difficult to ensure that the angle of each adjustment is the most appropriate, so a kind of speed measurement mechanism of coal belt conveyor is proposed to solve the above problems. CONTENT OF UTILITY MODEL

[0023] The utility model has the advantages of the following beneficial effects:

[0024] 1. In this utility model, after the speed measuring device is installed, the handle is turned to drive the worm gear to rotate. Since the worm gear meshes with the worm wheel, the worm wheel rotates accordingly, which in turn drives the rotating shaft to rotate, causing the connecting plate to rotate on the side wall of the fixed frame, thereby realizing the angle adjustment of the speed measuring device. This solves the problem of difficulty in accurately positioning when manually adjusting the angle. The above technical solution improves the accuracy and convenience of adjusting the angle of the speed measuring device.

[0025] 2. In this utility model, rotating the handle two drives the worm gear two to rotate. Since the worm gear two meshes with the worm wheel two, it drives the worm wheel two to rotate, which in turn causes the connecting rod to drive the gear to rotate. The rack inside the connecting column meshes with the gear, and the rotation of the gear drives the connecting column to move within the support column, thereby realizing the height adjustment of the speed measuring device. This solves the problem that the height of the traditional support column is fixed and cannot be flexibly adjusted to adapt to different usage scenarios. The above technical solution improves the flexibility and adaptability of the equipment. Attached Figure Description
