Description

Technical Field

[0001] This utility model relates to the technical field of buffering in coal samplers, and in particular to a buffering device for coal samplers. Background Technology

[0002] In the coal sampling process, the raw coal sampler buffer device plays an important role. Sampling involves extracting a small portion of material from the coal flow as a sample to represent the quality and properties of the entire coal flow. However, during the raw coal flow, there are problems such as unstable flow, impact, and vibration, which may affect the accuracy and representativeness of the sampling results. The emergence of the raw coal sampler buffer device has precisely solved these problems.

[0003] In the prior art, utility model patent CN220622591U discloses a buffer device for a raw coal sampler. This device includes a raw coal sampler, a disc shell fixedly connected to the outer wall of the sampler, a cylindrical shell fixedly connected to the lower surface of the disc shell, a sliding rod slidably connected to the inner wall of the cylindrical shell, a fixing block fixedly connected to the outer wall of the cylindrical shell, a groove on the lower surface of the sliding rod, a support column slidably connected to the inner wall of the groove, and a spring sleeved on the outer wall of the support column. This utility model utilizes the elasticity of the spring to buffer the longitudinal impact on the entire device. The disc shell also deforms with the vibration of the machine. The connecting rod hinged to the inner wall of the disc shell and the cylindrical rod, through the elasticity of the spring, also buffer the machine. This reduces the impact on the raw coal sampler, avoids the risk of wear and damage, and thus improves the service life of the raw coal sampler.

[0004] The aforementioned patented solution also has certain drawbacks. Although the handle on the raw coal collecting machine can be adjusted up and down, there is only one handle on the raw coal collecting machine. During sampling, it is difficult for the staff to stably hold the raw coal collecting machine with only one handle, which easily causes the raw coal collecting machine to sway from side to side, causing some inconvenience to use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a coal sampling machine buffer device that allows the operator to hold the coal sampling machine more stably while making the handle height adjustable, thus avoiding the left and right swaying of the coal sampling machine and bringing convenience to the operator.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a buffer device for a coal sampling machine, comprising a raw coal sampling machine and a hand-held assembly. A disc shell is fixedly connected to the outer wall of the raw coal sampling machine. The hand-held assembly includes a U-shaped handle. Two sets of connecting shafts are symmetrically fixedly arranged on the bottom inner side of the U-shaped handle. Two sets of connecting bushings are symmetrically fixedly arranged on the outer wall of the raw coal sampling machine. The U-shaped handle is rotatably mounted on the raw coal sampling machine through the cooperation of the connecting shafts and connecting bushings, and the U-shaped handle is located above the disc shell. A positioning plate is fixedly connected to the front side of the outer wall of the raw coal sampling machine. Multiple sets of positioning holes are arranged in an array around the connecting shafts. A T-shaped rod is slidably inserted into the right end of the U-shaped handle. The T-shaped rod slides through the positioning hole. An external thread is provided on the outer wall of the left end of the T-shaped rod. A threaded sleeve is fixedly arranged on the inner wall of the left side of the U-shaped handle. The left end of the T-shaped rod is screwed into the threaded sleeve through the external thread.

[0008] Preferably, an anti-slip grip sleeve is fixedly fitted on the outer circumference of the U-shaped grip, and the outer wall of the anti-slip grip sleeve is provided with anti-slip texture.

[0009] Preferably, the right end of the T-shaped insert is fitted with an anti-slip rubber sleeve.

[0010] Preferably, an annular pressure plate is fixedly sleeved on the outer wall of the T-shaped insert on the right side.

[0011] Preferably, an anti-loosening rubber pad is fixedly connected to the left end of the annular pressure plate, and the anti-loosening rubber pad is fitted onto the T-shaped insert.

[0012] Preferably, the left edge of the T-shaped insert has a chamfer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the height of the U-shaped handle can be adjusted according to the user's height. During adjustment, the T-shaped insert is rotated counterclockwise to disengage the left end of the T-shaped insert from the threaded sleeve. Then, the T-shaped insert is pulled out of the positioning hole, releasing the restriction on the U-shaped handle. The U-shaped handle can then be rotated and adjusted to a lower or higher position to accommodate users of different heights. After the U-shaped handle height is adjusted, the T-shaped insert is aligned with the corresponding positioning hole. Align the holes, then pass the T-shaped insert through the corresponding positioning hole and rotate the T-shaped insert clockwise to screw the left end of the T-shaped insert into the threaded sleeve. The T-shaped insert will then fix the U-shaped handle in place, allowing the operator to hold the U-shaped handle with both hands to stably support the coal collector and prevent it from swaying left and right during operation. This allows for easy adjustment of the handle height while providing greater stability for the operator, preventing swaying and making the machine more convenient to use. Attached Figure Description

Its working principle is as follows: During use, the height of the U-shaped handle 3 can be adjusted according to the operator's height. During adjustment, the T-shaped rod 8 is rotated counterclockwise to disengage its left end from the threaded sleeve 10. Then, the T-shaped rod 8 is pulled out of the positioning hole 7, releasing the restriction on the U-shaped handle 3. The U-shaped handle 3 can then be rotated to a lower or higher position to accommodate operators of different heights. After the height of the U-shaped handle 3 is adjusted, the T-shaped rod 8 is aligned with the corresponding positioning hole 7. The T-shaped rod 8 is then passed through the corresponding positioning hole 7 and rotated clockwise to screw its left end into the threaded sleeve 10. The T-shaped rod 8 fixes the position of the U-shaped handle 3, allowing the operator to hold the U-shaped handle 3 with both hands, stably supporting the coal sampling machine 1 and preventing it from swaying left and right during operation.
