[0002] An efficient puncher is a device specially used for punching holes in coal mines. It adopts the principle of high-low pressure conversion. It punches holes in the coal seam around the hole in sections, breaks the coal body, and expands the hole diameter through drilling. Then, a number of partition holes centered on the borehole are formed on the borehole, thereby releasing the stress and gas pressure around the borehole, improving the permeability of the coal seam, and promoting the efficiency of gas extraction.

[0003] During the construction of a high-efficiency puncher, coal dust can easily enter the inside of the puncher through the holes, causing the holes to be blocked and difficult to clean. As a result, under high pressure, the high-pressure water jet formed by the holes on the side of the puncher cannot be ejected, and the punching and hole-making function cannot be achieved.

[0007] Preferably, the movable frame includes a connecting ring, a cleaning brush plate, a second spring, and a filter screen. The movable frame is composed of two annular connecting rings, and an annular filter screen is connected between the contact surface with the inner wall tube. The filter screen is arranged corresponding to the holes opened on the inner wall tube, and is sleeved on the outer circumference of the inner wall tube. A cleaning brush plate is arranged on the filter screen, and the cleaning brush plate is located between the two connecting rings and is connected to the two connecting rings through a second spring. A cleaning brush is arranged on the cleaning brush plate, and the cleaning brush is in conflict with the filter screen.

[0008] Preferably, it also includes a fixed frame, which is fixedly connected to the outer circumference of one end of the inner wall tube corresponding to the drill rod, and is symmetrically arranged on the left and right sides of the push-pull plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The coal impurities are directly intercepted by the filter. Since the gap of the filter is small, it is beneficial to prevent the coal from entering the holes of the inner wall tube and causing blockage. The elastic potential energy of the spring is converted into kinetic energy.

When the water pressure changes from high pressure to low pressure, the thrust of the water pressure on the stamping plate decreases. The first spring uses its telescopic principle to pull the mobile frame back to the top of the hole, and uses the water pressure to push the mobile frame to move, which helps to reduce the resistance of the water pressure to the hole. The stretching rebound force of the spring is used to control the movement of the mobile frame, and the mobile frame is effectively returned to its position. At the same time, the elastic potential energy of the third spring is used to drive the scraper to slide, and the coal impurities remaining on the inner wall of the cavity are pushed to the connecting hole, and then discharged through the drill bit.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figure 1-3 The utility model provides an embodiment: a high-efficiency puncher, including a puncher shell 1 and an inner wall tube 5, the front and rear ends of the puncher shell 1 are respectively provided with an internal thread groove 4 and an external thread joint 3, respectively connected to the drill bit and the drill rod, the inner wall tube 5 is connected to the inside of the puncher shell 1, a cavity is provided between the inner wall tube 5 and the puncher shell 1, a plurality of holes 2 are respectively opened on the inner wall tube 5 and the puncher shell 1, the holes 2 are symmetrical to each other, a plurality of movable frames 6 are sleeved on the outer circumference of the inner wall tube 5, located inside On the left and right sides of the hole 2 opened on the wall tube 5, every two movable frames 6 are connected by a connecting plate 7, and the connecting plate 7 is slidably matched with the slide groove opened on the inner wall tube 5. The movable frame 6 is slidably matched with the inner wall tube 5. A linkage slide groove is symmetrically opened on the outer circumference of the inner wall tube 5 corresponding to one end of the drill rod. Push-pull plates 8 are slidably matched in the linkage slide groove. The push-pull plates 8 are connected to the movable frame 6. The bottom ends of the two push-pull plates 8 pass through the inner wall tube 5 and are connected with a stamping plate 10. A connecting groove 24 is symmetrically opened on the inner wall tube 5 corresponding to one end of the drill bit.

[0026] The movable frame 6 includes a connecting ring, a cleaning brush plate 14, a spring 16, and a filter 17. The movable frame 6 is composed of two annular connecting rings. An annular filter 17 is connected between the contact surface with the inner wall tube 5. The filter 17 is arranged corresponding to the hole 2 opened on the inner wall tube 5 to effectively prevent impurities from entering the inner wall tube 5. The filter 17 is sleeved on the outer circumference of the inner wall tube 5. A cleaning brush plate 14 is arranged on the filter 17. The cleaning brush plate 14 is located between the two connecting rings and is connected to the two connecting rings through the spring 16. The elastic potential energy of the spring 16 drives the cleaning brush plate 14 to move slightly to clean the surface of the filter 17. A cleaning brush 15 is arranged on the cleaning brush plate 14, and the cleaning brush 15 conflicts with the filter 17.

[0027] The stamping plate 10 is connected to a symmetrically arranged outer expansion plate 11 on the corresponding water inlet end. The outer expansion plate 11 and the stamping plate 10 form a water flow blocking effect. The movable frame 6 is moved by increasing or decreasing the water pressure of the water flow, which is used to increase the stamping effect and move the movable frame 6. The outer expansion plate 11 is arranged in an arc shape at the contact end with the water flow, which increases the water flow stamping effect and generates stronger pressure and impact force. The enhanced impact force helps the movable frame 6 to move more effectively during operation, thereby blocking or opening the hole 2 opened on the inner wall tube 5.

[0028] By providing a puncher shell 1, an inner wall tube 5, a hole 2, a movable frame 6, a spring 16, a cleaning brush plate 14, a cleaning brush 15 and a filter 17, when the puncher rotates, if coal enters from the hole 2 of the puncher shell 1, the filter 17 on the inner wall tube 5 isolates the coal in the cavity, wherein the spring 16 uses its own elastic potential energy to drive the cleaning brush plate 14 to move up and down, and drives the cleaning brush 15 to perform a cleaning action on the filter 17. During the process, the filter 17 directly intercepts coal impurities through its structure. Since the gap of the filter 17 is small, it is conducive to intercepting coal from entering the hole 2 of the inner wall tube 5 to cause blockage. The elastic potential energy of the spring 13 is converted into kinetic energy, and the cleaning brush 15 is driven to perform a cleaning action on the filter 17 through the rotation of the puncher. The cleaning brush 15 can effectively clean and adsorb the coal impurities on the filter 17 through the contact and friction between its bristles and the surface of the object.

[0029] Example 2: Please refer to Figure 2 , 5 , based on Example 1, it also has the following structure:

[0030] The punch housing 1 is symmetrically provided with oblique triangular slopes corresponding to the connecting grooves 24, and the oblique ends of the slopes are connected to fixed blocks 19. The arc plate 20 and the scraper 22 are both obliquely arranged in the triangular slope. The fixed block 19 is obliquely arranged at the oblique end, so that the overall oblique arrangement provides stable support and position fixation to prevent the components from moving or failing during operation. The fixed block 19 is connected to an arc plate 20, which adjusts the flow and direction of the fluid during movement and guides the coal impurities into the connecting groove 24, thereby introducing them into the inner wall tube 5. The bottom end of the arc plate 20 is connected to a spring three 21, and the bottom end of the spring three 21 is connected to a scraper 22. The scraper 22 cleans the impurities in the cavity and is driven to reciprocate by the action of the spring three 21.

[0031] The scraper 22 is provided with a conical barb 23 at the contact end of the oblique end in the slope, and the other end of the conical barb 23 abuts against the inner wall of the slope, so that the conical barb 23 can clean the inner wall of the oblique end when the scraper 22 moves. The conical barb 23 can effectively remove the residue on the inner wall of the slope through its special shape and position to prevent blockage or accumulation.

[0032] By arranging a fixed block 19, an arc plate 20, a spring three 21, a scraper 22, and a conical barb 23 inside the punch housing 1, when coal impurities pass through the cavity and enter the connecting hole of the inner wall tube 5, they impact downward, and the elastic characteristics of the spring three 21 are used to drive the scraper 22 to move up and down, pushing the coal impurities remaining on the inner wall of the cavity to the connecting groove 24. The two ends of the punch are connected to the drill rod and the drill bit through the external threaded joint 3 and the internal threaded hole respectively, and the drill bit discharges the coal impurities in the cavity.

[0033] Example 3: Please refer to Figure 3-4 , based on Example 1, it also has the following structure:

[0034] It also includes a fixing frame 9, which is fixedly connected to the outer circumference of one end of the inner wall tube 5 corresponding to the drill rod. The fixing frame 9 provides stable support and fixed position to ensure that the spring 13 drives the movable frame 6 to reset after moving, and is symmetrically arranged on the left and right sides of the push-pull plate 8. The fixing frame 9 is respectively fixedly connected with symmetrically arranged bosses 12, and the boss 12 is connected with a spring 13. The spring 13 is connected to the boss 12, one end of which is connected to the connecting ring, and the other end provides elastic support for resetting the movable frame 6 after moving, so that the movable frame 6 can quickly return to the predetermined initial position after operation, ensuring that the equipment can be accurately reset after each operation. The other end of the spring 13 is connected to the connecting ring for resetting the movable frame 6 after moving.

[0035] By arranging the connecting plate 7, the sliding seat 18, the push-pull plate 8, the stamping plate 10, the expansion plate 11, the fixing frame 9, the boss 12 and the spring 13, when the water pressure inside the puncher changes from low pressure to high pressure, the water pressure applies a thrust to the stamping plate 10, pushing the push-pull plate 8 to move, so that the filter screen 17 is separated from the hole 2. When the water pressure changes from high pressure to low pressure, the thrust on the stamping plate 10 is reduced, and the spring 13 uses its telescopic principle to pull the movable frame 6 back to the top of the hole 2. In this process, the movable frame 6 is moved by the water pressure, which helps to reduce the resistance when the water pressure rushes out of the hole 2. The rebound force after the spring is stretched is used to control the movement of the movable frame 6, and the movable frame 6 is effectively returned to its original position.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
