It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: Figure 1-Figure 3As shown, the utility model provides a pneumatic core tube rapid sampler, comprising: an inner tube 1, an outer tube 2 is fixedly sleeved on the outer wall of the inner tube 1, a cylinder 3 is fixedly arranged at one end of the outer tube 2, a threaded hole 4 is penetrated through one end of the inner tube 1, a threaded push rod 5 is fixedly connected to the telescopic end of the cylinder 3, the threaded push rod 5 is penetrated and inserted into the inside of the threaded hole 4, the threaded push rod 5 is threadedly connected to the threaded hole 4, a diamond composite piece 6 is fixedly arranged on the outer wall of one end of the outer tube 2 close to the cylinder 3, and a baffle 7 is movably arranged inside the inner tube 1.

[0022] The effect achieved by the entire embodiment 1 is as follows: a hollow steel pipe with a thickness of 0.3mm, a length of 80cm, and an inner diameter of 90mm is taken as the outer tube 2 of the sampler, and then a steel pipe with a length of 90cm and an inner diameter of 75mm is put inside it as the inner tube 1 of the sampler, and a threaded head is used at the bottom of the inner tube 1 to achieve the purpose of connecting the drill pipe; secondly, an air inlet 8 with a diameter of 4cm is left between the inner tube 1 and the outer tube 2 to facilitate air circulation between the tube walls of the inner tube 1 and the outer tube 2, thereby achieving the purpose of cooling, and a diamond composite sheet 6 is fixedly installed on the outer wall of the outer tube 2 to increase the rigidity of the outer tube 2 and also facilitate the removal of the sampler from the rock mass; then, a threaded hole 4 with a diameter of 2.5cm is opened through one end of the inner tube 1, and a threaded push rod 5 with a diameter of 2cm is inserted through the inside of the threaded hole 4 to meet the effect of thread thrust, and then a baffle 7 with a diameter of 70mm is installed inside the inner tube 1 to prevent the coal sample from flowing along the drill pipe.

[0023] Example 2: Figure 1-Figure 3 As shown, an air inlet hole 8 is opened between the two ends of the inner tube 1 and the outer tube 2, and the length of the air inlet hole 8 is 4 cm; an air outlet hole 9 is opened at the other end of the inner tube 1 and the outer tube 2, and a diamond tooth 10 is fixedly installed on the end of the inner tube 1 and the outer tube 2 away from the cylinder 3; the thickness of the outer tube 2 is 0.3 mm, the length of the outer tube 2 is 80 cm, and the inner diameter of the outer tube 2 is 90 mm; the length of the inner tube 1 is 90 cm, and the inner diameter of the inner tube 1 is 75 mm; the diameter of the threaded hole 4 is 2.5 cm, the diameter of the threaded push rod 5 is 2 cm; the diameter of the baffle 7 is 70 mm.

Then put a steel pipe with a length of 90cm and an inner diameter of 75mm inside it, and set it as the inner tube 1 of the sampler. Use a threaded head at the bottom of the inner tube 1 to connect the drill rod; secondly, leave an air inlet hole 8 with a diameter of 4cm between the inner tube 1 and the outer tube 2 to facilitate air circulation between the walls of the inner tube 1 and the outer tube 2, so as to achieve the purpose of cooling. A diamond composite sheet 6 is fixed on the outer wall of the outer tube 2 to increase the rigidity of the outer tube 2 and also to facilitate the sampler from the rock mass. Then, a threaded hole 4 with a diameter of 2.5 cm is drilled through one end of the inner tube 1, and a threaded push rod 5 with a diameter of 2 cm is inserted into the threaded hole 4 to meet the effect of thread adding thrust, and then a baffle 7 with a diameter of 70 mm is installed inside the inner tube 1 to prevent the coal rock sample from flowing along the drill pipe; finally, diamond teeth 10 are welded at one end of the inner tube 1 and the outer tube 2 to facilitate insertion into the rock mass for extracting rock samples, and a cylinder 3 is fixed at one end of the outer tube 2. After taking out the rock mass, the cylinder 3 is used to uniformly drive the threaded push rod 5 to slowly push the core out of the inner tube 1 so that the integrity of the sample can be maintained to the greatest extent.
