Description

Technical Field

[0001] This utility model relates to the field of coal drilling and sampling technology, and in particular to a coal drilling and sampling device. Background Technology

[0002] Coal sampling is a crucial means to ensure the rational development, efficient utilization, and safe production of coal resources. Coal seams are not homogeneous; the properties of coal vary in different locations. By analyzing samples from multiple sampling points, we can understand the changing patterns of coal seam structure and coal quality, providing a basis for mining plans. Before mining, based on the coal hardness and thickness determined by sampling analysis, we can rationally select mining equipment, improve mining efficiency, and reduce equipment wear. We can also formulate scientific mining plans based on sampling results, avoiding over-mining or unreasonable mining, improving resource recovery rates, and achieving sustainable utilization of coal resources. However, the coal drilling and sampling process generates a large amount of coal dust, which permeates the working environment, making the surrounding air turbid and affecting the overall quality of the working environment. Utility Model Content

Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 5 As shown, a preferred embodiment of the present invention provides a coal drilling and sampling device, comprising a frame 1, and a drive mechanism 2, a drilling and sampling mechanism 3, and a dust collection mechanism 4 disposed on the frame 1. The output end of the drive mechanism 2 is connected to the drilling and sampling mechanism 3 and can drive the drilling and sampling mechanism 3 to move up and down. The dust collection mechanism 4 includes a dust collection box 41 and a dust collection pipe 42. The dust collection box 41 is provided with a dust collection fan 43 and is connected to the dust collection pipe 42. The frame 1 is provided with a positioning ring 44 for fixing the dust collection pipe 42 on the frame 1. The dust collection port of the dust collection pipe 42 faces the drilling hole of the drilling and sampling mechanism 3.

[0020] When the drilling and sampling mechanism 3 is drilling, the dust collection mechanism 4 is activated, and the dust collection pipe 42 adsorbs and collects the coal dust generated during drilling into the dust collection box 41. The positioning ring 44 effectively fixes the dust collection pipe 42, ensuring that the dust collection port of the dust collection pipe 42 is accurately facing the drilling site of the drilling and sampling mechanism 3, thereby improving the coal dust collection efficiency, preventing the spread of coal dust, and improving the quality of the working environment.

[0021] For example, such as Figure 1 , 2 As shown in Figure 5, the drive mechanism 2 includes a fixed frame 21, a drive motor 22, a drive gear 23, a drive rack 24, and a mounting plate 25 for mounting the drilling and sampling mechanism 3. The fixed frame 21 is fixed on the frame 1, and the drive motor 22 is mounted on the fixed frame 21. The output end of the drive motor 22 is engaged with the drive gear 23, and the drive gear 23 is meshed with the drive rack 24. The drive rack 24 is slidably engaged with the fixed frame 21. The bottom of the drive rack 24 is connected to the mounting plate 25. When drilling and sampling, the drive motor 22 drives the drive gear 23 to rotate, and the drive gear 23 drives the drive rack 24 and the drilling and sampling mechanism 3 to move downward.

[0022] Furthermore, such as Figure 1 , 2 As shown in Figure 4, the fixed frame 21 is rotatably connected to a driven gear 26 that meshes with the drive gear 23. The driven gear 26 is meshed with a driven rack 27 that slides up and down with the fixed frame 21. The bottom of the driven rack 27 is connected to the mounting plate 25. When the drive gear 23 moves, it simultaneously drives the driven gear 26 to rotate, so that the drive rack 24 and the driven rack 27 can rise or fall synchronously, improving the stability of the drilling and extraction mechanism 3 when drilling and descending, and improving the transmission efficiency. This avoids the problem of uneven load caused by unilateral force and prevents the drilling and extraction mechanism 3 from tilting during drilling and extraction.

[0023] For example, such as Figure 4 As shown, a damper 28 is provided between the drive rack 24 and the mounting plate 25, and a damper 28 is provided between the driven rack 27 and the mounting plate 25. The damper 28 can absorb and buffer the impact and vibration generated by the drilling and mining mechanism 3 during the drilling and mining process, avoid the vibration of the entire coal drilling and sampling device, enable the frame 1 to stand stably on the ground, effectively protect the drilling and mining mechanism 3, and improve the quality of drilling and sampling.

[0024] Furthermore, such as Figure 4 As shown, the top of the two dampers 28 is provided with a baffle 29, and a spring 281 is provided on the outer sleeve of the damper 28. The spring 281 is sandwiched between the baffle 29 and the mounting plate 25. The spring 281 cooperates with the damper 28 to further improve the shock absorption effect.

[0025] In this embodiment, as Figure 1 , 2 As shown in Figure 4, the drilling and mining mechanism 3 includes a drilling and mining motor 31, a drill rod 32, a core tube 33, and a drill bit 34. The drilling and mining motor 31 is mounted on the mounting plate 25. The driven rack 27 and the driving rack 24 are symmetrically arranged on both sides of the drilling and mining motor 31. The drill rod 32 is connected to the output end of the drilling and mining motor 31, and the core tube 33 is connected between the drill rod 32 and the drill bit 34. During sampling, the drilling and mining motor 31 starts and drives the drill rod 32, and the drill rod 32 drives the core tube 33 and the drill bit 34 to rotate at high speed. At the same time, the driving mechanism 2 drives the entire drilling and mining mechanism 3 to gradually move downward to drill and sample the coal.

[0026] For example, such as Figure 1 As shown, the top of the frame 1 is provided with a guide frame 11. The guide frame 11 is provided with a first sliding groove 111 that slides with the drive rack 24 and a second sliding groove 112 that slides with the driven rack 27, thereby improving the stability and accuracy of the up-and-down movement of the drive rack 24 and the driven rack 27, and thus improving the working quality of the drilling and production mechanism 3.

[0027] Specifically, such as Figure 3 As shown, the dust collection box 41 is equipped with a cleaning door 411. The dust collection box 41 is equipped with a dust filter 45 to divide the inner cavity of the dust collection box 41 into a dust collection chamber and an exhaust chamber. The dust extraction fan 43 is connected to the exhaust chamber. The dust filter 45 can prevent coal dust from entering the dust extraction fan 43. After drilling and sampling, the staff can open the cleaning door 411 to clean the coal dust and the dust filter 45 in the dust collection chamber.

[0028] For example, such as Figure 5 As shown, the frame 1 has four adjustable feet 5 at its bottom corners. Further, each adjustable foot 5 includes an adjustable base 51 and a fixing rod 52. The fixing rod 52 is rotatably connected to the frame 1. The adjustable base 51 has an internal threaded cavity 511 that engages with the lower threaded rod of the fixing rod 52. For uneven ground, the depth of the lower threaded rod of the fixing rod 52 extending into the internal threaded cavity 511 is adjusted by turning the fixing rod 52. By adjusting the height of each adjustable foot 5, the unevenness or tilt of the ground is compensated for, ensuring that the frame 1 can be placed stably on the ground, keeping the frame 1 level, and avoiding stress concentration or the risk of tipping due to single-point suspension.

[0029] The entire working process is as follows: Place the coal drilling and sampling device on the sampling ground. First, adjust the frame 1 using the four adjusting feet 5 to adapt to the uneven ground. Then, start the drive motor 22, drilling and sampling motor 31, and dust extraction fan 43. The drive rack 24 and driven rack 27 descend synchronously, causing the drilling and sampling mechanism 3 to move downwards to start drilling and sampling at the location to be sampled. The dust extraction pipe 42 immediately absorbs the generated coal dust and sends it into the dust collection box 41. After the drill bit 34 reaches the required position, stop the drilling and sampling motor 31, and then reverse the output end of the drive motor 22 so that the drive rack 24 and driven rack 27 rise synchronously to reset. Stop the drive motor 22 and dust extraction fan 43. The workers take out the coal collected by the drilling and sampling mechanism 3. Finally, open the cleaning door 411 to clean the coal dust in the dust collection box 41.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
