Description

Technical Field

[0001] The utility model relates to the technical field of surveying and sampling, in particular to a drill bit for surveying and sampling potash mines. Background Art

[0002] Potash mines are important raw materials for extracting potassium and potassium compounds. The potassium and potassium compounds extracted from potash mines are widely used in industry and agriculture. In agriculture, potassium and potassium compounds are mainly used to make potash fertilizers, which have a significant yield-increasing effect on the growth of crops and are necessary resources for the development of agriculture.

[0003] In industry, potassium salts play an important role in the manufacture of detergents, glass, ceramics, textile dyes, chemicals, etc. In addition, potassium chlorate, superphosphate and nitrate are also important raw materials for the manufacture of matches, fireworks, explosives and rockets.

[0004] With the development of industry and agriculture, the demand for potassium salt is gradually increasing, which requires deep mining of existing potassium salt mines and surveying of undiscovered potassium salt mines. Surveying potassium salt mines requires sampling and testing of the extracted samples to analyze the content and location of the potassium salt mines, which facilitates the subsequent mining of potassium salt mines.

[0005] The deep development of existing potash mines also requires sampling and analysis of the potash mines to analyze the content of the existing potash mines and determine how to conduct deep development of the potash mines.

[0006] In the process of sampling potash mines, sampling drills are required. When the existing sampling drills are used to transport samples outward, samples may fall out of the sampling drills, resulting in the sample being unable to be transported to the hands of testers, affecting the testers' detection of the samples, and further affecting the testers' judgment of the potash mines.

[0047] In an optional embodiment of the present utility model, in addition to the same parts as the previous embodiment, the cutting mechanism further includes: a sampling outer cylinder 6;

[0048] A shaft is provided at the upper end of the sampling outer cylinder 6, and the shaft is rotatably installed in a groove provided at the lower end of the positioning block 3. The end of the shaft is fixedly connected to the shaft of the motor, and the motor is installed inside the positioning block 3; a slide groove is provided at the lower part of the outer wall of the sampling outer cylinder 6, and a handle provided on the outer wall of the rotating plate 10 is slidably installed in the slide groove. A groove is provided on the inner wall of the sampling outer cylinder 6 at a position corresponding to the outer wall slide groove, and the rotating plate 10 is rotatably installed in the groove.

[0049] Working principle: When it is necessary to survey and sample potash mines, use this equipment, first drill a survey hole at the place to be surveyed, then connect the carrying rod 1 with the connecting sleeve 2, insert the external wrench into the groove provided on the side of the threaded rod 22, use the external wrench to rotate the threaded rod 22, and then drive the tilt control plate 21 to move, thereby driving the flip plate 19 to flip around the support frame 18, and then drive the cutting plate 20 to flip, and then make the cutting plate 20 tilt at a certain angle, and tilt the cutting plate 20 at a specified angle according to the actual situation. Cutting plates 20 tilted at different angles are suitable for different geology;

[0050] Then, the device is placed in the survey hole, the end of the outer push rod 5 contacts the hole wall, and then the carrying rod 1 is lowered to drive the device downward, so that the bottom of the device contacts the bottom of the survey hole, and then the cutting plate 20 contacts the bottom of the hole, and then the motor connected to the sampling outer cylinder 6 drives the sampling outer cylinder 6 to rotate, and then drives the limiting plate 17 to rotate, thereby driving the cutting plate 20 to rotate, and then crushing the mineral. In the process of the cutting plate 20 crushing the mineral, the carrying rod 1 then drives the device downward, and the cutting plate 20 crushes the mineral on the outside, and the mineral in the middle enters the sampling inner cylinder 7;

[0051] The device moves downward, so that more and more minerals are added to the sampling inner cylinder 7 until the minerals contact the inner top plate 14. At this time, the minerals push the inner top plate 14 upward, and then drive the inner top rod 15 upward, thereby driving the outer top plate 13 upward, and then drive the clamping rod 11 upward, so that the clamping rod 11 is taken out of the hole provided on the rotating plate 10. At this time, the spring provided on the side of the slide bar 16 pulls the slide bar 16 to move to the inside of the sampling inner cylinder 7, and then drives the sealing plate 9 to move to the inside of the sampling inner cylinder 7. At the same time, the carrying rod 1 is no longer lowering the device;

[0052] The motor connected to the sampling outer cylinder 6 drives the sampling outer cylinder 6 to rotate, and then drives the connecting plate 8 to rotate, thereby driving the sealing plate 9 to rotate, and then the sealing plate 9 is rotated in the process of moving toward the inner side of the sampling inner cylinder 7, and then the minerals entering the sampling inner cylinder 7 are separated from the minerals outside the sampling inner cylinder 7. When the multiple sealing plates 9 are closed, the multiple sealing plates 9 separate the minerals in the sampling inner cylinder 7 from the minerals outside the sampling inner cylinder 7. At this time, the motor connected to the sampling outer cylinder 6 stops rotating, the carrying rod 1 moves up to drive the equipment to move up, and then the equipment is taken out, and the multiple sealing plates 9 seal the lower end of the sampling inner cylinder 7, effectively preventing the minerals in the sampling inner cylinder 7 from falling out of the sampling inner cylinder 7;

[0053] During the movement of the sealing plate 9, the sliding rod 16 is driven to slide in the sliding groove of the rotating plate 10, thereby driving the rotating plate 10 to rotate;

[0054] After the carrying rod 1 takes the equipment out of the survey hole, the handle connected to the outer wall of the rotating plate 10 is manually turned, and then the rotating plate 10 is driven to rotate, so that the sliding rod 16 slides in the opposite direction in the sliding groove of the rotating plate 10, and then the sealing plate 9 slides in the opposite direction in the sliding groove of the connecting plate 8, so that multiple sealing plates 9 are separated, and then the opening at the lower end of the sampling inner cylinder 7 is opened. At this time, the sample in the sampling inner cylinder 7 slides out of the sampling inner cylinder 7 under the action of gravity, and the inner top plate 14 moves downward under the action of the spring, and then drives the inner top rod 15 to move downward, thereby driving the outer top plate 13 to move downward, and then drives the clamping rod 11 to move downward, so that the clamping rod 11 is inserted into the hole provided on the rotating plate 10, fixes the rotating plate 10, and then fixes the sliding rod 16, thereby fixing the sealing plate 9, and then facilitates the next use;

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
