Description

Technical Field

[0001] This utility model belongs to the technical field of coal sampler counting equipment, specifically relating to a stable counting device for a coal sampler. Background Technology

[0002] Currently, the coordinate positioning of the coal sampler uses an encoder for counting, and the encoder is connected to the step counting wheel via a coupling. When the step counting wheel moves and rotates with the trolley, the encoder rotates through the coupling, thus achieving the purpose of counting.

[0003] In actual use, due to factors such as uneven tracks and equipment vibration, the counting wheels may become suspended or stop rotating during the operation of the trolley. This causes discrepancies between the system count and the actual operation, ultimately leading to inaccurate sampling coordinate positioning and equipment accidents such as collisions between the sampling drill and the carriage tie rods. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a stable counting device for a coal sampler.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A stable counting device for a coal sampler includes a movable track, a step counting wheel movable plate, a coupling, and an encoder. The movable track is set on the side wall of the coal sampler. The step counting wheel movable plate is slidably set inside the movable track. The coupling is set in the middle of the step counting wheel movable plate and its lower end passes through the step counting wheel movable plate and is connected to the step counting wheel. The encoder is set on the upper end of the coupling.

[0007] It also includes an adjustment device, two fixing screws and a stabilizing spring. The adjustment device includes two adjustment plates, which are horizontally and symmetrically fixed to the lower part of the side wall of the coal sampler on both sides of the movable track. Several adjustment and fixing holes are evenly opened on the adjustment plates. Both ends of the stabilizing spring are provided with collars. The upper middle part of the movable plate of the step counting wheel is provided with a fixing ring. The stabilizing spring passes through the fixing ring in the middle and is symmetrically fixed in the adjustment and fixing holes on both sides by fixing screws passing through the collars.

[0008] Furthermore, a fixed seat is provided between the coupling and the movable plate of the step counter wheel.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By setting a stabilizing spring, this utility model can limit the vibration amplitude of the moving plate of the step counting wheel, effectively preventing the step counting wheel from being suspended in the air and inaccurate counting due to it getting stuck on the upper end of the moving track;

[0011] 2. By setting a stabilizing spring adjustment device, this utility model can ensure the elasticity of the stabilizing spring and ensure that the step counting wheel will not be suspended in the air. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a stable counting device for a coal sampler includes a movable track 2, a step counting wheel movable plate 3, a fixed seat 4, a coupling 5, and an encoder 6. The movable track 2 is set on the side wall of the coal sampler 1. The step counting wheel movable plate 3 is slidably set in the movable track 2. The fixed seat 4 is set in the middle of the step counting wheel movable plate 3. The coupling 5 is set on the fixed seat 4, and its lower end passes through the step counting wheel movable plate 3 and the fixed seat 4 to connect with the step counting wheel. The encoder 6 is set on the upper end of the coupling 5.

[0016] It also includes an adjustment device, two fixing screws 9 and a stabilizing spring 10. The adjustment device includes two adjustment plates 7, which are horizontally and symmetrically fixed to the lower part of the side wall of the coal sampler 1 on both sides of the movable track 2. Several adjustment fixing holes 8 are evenly opened on the adjustment plates 7. Both ends of the stabilizing spring 10 are provided with collars 11. The upper middle part of the movable plate 3 of the step counting wheel is provided with a fixing ring 12. The stabilizing spring 10 passes through the fixing ring 12 in the middle, and both ends are symmetrically fixed in the adjustment fixing holes 8 on both sides by fixing screws 9 passing through the collars 11.

[0017] The working process of this utility model:

[0018] The coordinate positioning of the coal sampler 1 is counted using the encoder 6. When in use, the counting wheel moves and rotates with the trolley, and the encoder 6 is connected to the coupling 5 to rotate, thereby achieving the counting function.

[0019] When encountering factors such as uneven track or equipment vibration, the movable plate 3 of the step counting wheel may slide to the top of the movable track 2 and get stuck due to vibration, causing the step counting wheel to be suspended in the air and not rotate.

[0020] Insert the fixing screws 9 into the collars 11 at both ends of the stabilizing spring 10 and into the symmetrical adjustment fixing holes 8 to tighten the stabilizing spring 10, thereby stabilizing the pedometer wheel movable plate 3, reducing its vibration amplitude, and preventing it from getting stuck on the upper end of the movable track 2. When the elasticity of the stabilizing spring 10 weakens, the fixing screws 9 can be inserted into the adjustment fixing holes 8 further away to adjust the spring 10's bounce, ensuring that the pedometer wheel movable plate 3 will not get stuck on the upper end of the movable track 2, thus preventing the pedometer wheel from becoming suspended.
