[0002] A coal survey sampler is a tool used to collect coal samples during coal surveying. A drill sampler is a common type of coal survey sampler. A traditional drill sampler is composed of a driving device, a sampler body, a handle, a sampling tube and other main components. The sampling tube is driven by the driving device to vibrate and insert into the ground, thereby completing the sampling work. However, after the sample is taken out of the inner cavity of the sampling tube, there will be sampling residues, which will interfere with the next sampling work. Cleaning the sampling residues in the inner cavity of the sampling tube is very time-consuming and labor-intensive. In order to solve the shortcomings of the existing technology, we propose a sampler that is easy to clean for coal surveying. Utility Model Content

[0006] Wherein, the air pump is connected to the inner cavity of the fixing tube through a hose, and the central axis of the piston rod coincides with the central axis of the mounting tube.

[0007] Wherein, the bolt is used to fix the annular cotton towel to the bottom of the piston rod.

[0008] In which, the gripping assembly includes a movable rod, which is slidably connected to the inner wall of the sampler body, the bottom end of the movable rod is fixedly connected to a handle, the outer wall of the movable rod is fixedly connected to baffle 1, the top of the movable rod is fixedly connected to baffle 2, the outer wall of the movable rod is provided with an arc-shaped slot, the top of the sampler body is fixedly connected to a square frame, the inner wall of the square frame is slidably connected to an arc-shaped block, the outer surface of one side of the arc-shaped block is fixedly connected to a spring, and the end of the spring away from the arc-shaped block is fixedly connected to the inner wall of the square frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model uses a cleaning component including a ring-shaped cotton towel. When the device is sampling, the sampling tube is threadedly connected to the outer wall of the mounting tube. After the sample is taken out, the air pump is controlled to repeatedly inject and extract air into the inner cavity of the fixed tube, at which time the connecting tube and the piston rod are driven to move back and forth, thereby driving the ring-shaped cotton towel to wipe the inner wall of the sampling tube. At the same time, water can be poured into the air vent to improve the wiping effect of the ring-shaped cotton towel. After the sampling tube is disassembled, the bolt can be loosened and the ring-shaped cotton towel can be replaced. With the above structure, the air pump repeatedly extracts and injects air into the inner cavity of the fixed tube, which can drive the piston rod and the ring-shaped cotton towel to move up and down, and the sampling residue in the inner cavity of the sampling tube can be cleaned, thereby avoiding interference with the next sampling, saving the user's time and physical effort in cleaning the sampling tube, and improving the flexibility of the device.

[0013] The utility model uses a gripping assembly including a movable rod. When sampling is completed and the device is to be picked up, the movable rod can be pulled to overcome the blocking of the arc-shaped block. After the positions of the movable rod and the handle are adjusted, the arc-shaped block is pushed by the square frame to block one of the arc-shaped slots. At this time, the movable rod cannot slide relative to the sampler body, and the user can pick up the device by holding one of the grips and the handle. Using the above structure, the user can pick up the device by holding the handle, avoiding dirtying the palm of the hand by directly holding the sampling tube, and the position of the handle can be adjusted according to the user's situation, thereby improving the practicality of the device.

A piston rod 36 is slidably connected to the inner wall of the connecting tube 35. An annular cotton towel 37 is provided at the bottom of the piston rod 36, and a bolt 38 is threadedly connected to the inner wall of the piston rod 36. An air pump 39 is fixedly mounted on the top of the sampler body 1, and a hose 311 is fixedly connected to the air outlet of the air pump 39, and the end of the hose 311 away from the air pump 39 is fixedly connected to the top of the fixing tube 34.

[0023] The air pump 39 is connected to the inner cavity of the fixing tube 34 through the hose 311, and the central axis of the piston rod 36 coincides with the central axis of the mounting tube 31;

[0024] The air is pumped into the inner cavity of the fixed tube 34 through the air pump 39, which can push the connecting tube 35 and the piston rod 36 downward, driving the annular cotton towel 37 to wipe the inner wall of the sampling tube 32. When the air pump 39 extracts the air from the inner cavity of the fixed tube 34, the atmospheric pressure will push the piston rod 36 and the connecting tube 35 upward to return to their original position.

[0025] The bolt 38 is used to fix the annular cotton towel 37 to the bottom of the piston rod 36 .

[0026] Among them, the grasping assembly 4 includes a movable rod 41, which is slidingly connected to the inner wall of the sampler body 1, the bottom end of the movable rod 41 is fixedly connected to a handle 42, the outer wall of the movable rod 41 is fixedly connected to a baffle 1 43, the top of the movable rod 41 is fixedly connected to a baffle 2 44, the outer wall of the movable rod 41 is provided with an arc-shaped slot 45, the top of the sampler body 1 is fixedly connected to a square frame 46, the inner wall of the square frame 46 is slidingly connected to an arc-shaped block 47, the outer surface of one side of the arc-shaped block 47 is fixedly connected to a spring 48, and the end of the spring 48 away from the arc-shaped block 47 is fixedly connected to the inner wall of the square frame 46.

[0027] The length direction of the movable rod 41 is parallel to the length direction of the sampling tube 32, the movable direction of the arc-shaped block 47 is perpendicular to the length direction of the movable rod 41, and the baffle 2 44 and the baffle 1 43 are respectively located on the upper and lower sides of the sampler body 1;

[0030] The working process of this utility model is as follows:

[0031] First, when sampling the device, the sampling tube 32 is threadedly connected to the outer wall of the mounting tube 31. After taking the sample, the air pump 39 is controlled to repeatedly inject and extract air into the inner cavity of the fixed tube 34. At this time, the connecting tube 35 and the piston rod 36 will move up and down, thereby driving the annular cotton towel 37 to wipe the inner wall of the sampling tube 32. At the same time, water can be poured into the air vent 33 to improve the wiping effect of the annular cotton towel 37. After the sampling tube 32 is removed, the bolt 38 can be loosened and the annular cotton towel 37 can be replaced. When the sampling is completed and the device is to be picked up, the movable rod 41 can be pulled to make the movable rod 41 overcome the locking of the arc-shaped block 47.
