[0006] A coal cutting device for coal mining includes a base and a cutting mechanism. The cutting mechanism includes a housing, in which a motor is installed. A drive rod is fixedly connected to the output end of the motor, and the drive rod passes through and is rotatably connected to the housing. A cutting blade is fixedly connected to the drive rod. A support frame is fixedly connected to the lower part of the housing, and a ball seat is fixedly connected to the lower end of the support frame. A movable groove is formed on the base, and the ball seat slides in the movable groove. A ball groove is formed on the lower end face of the ball seat, and a rolling ball rolls in the ball groove. A gripping mechanism is provided on the housing.

[0012] Furthermore, the free end of the connecting frame is arc-shaped.

[0013] Furthermore, a water storage tank is fixedly connected to the inner wall of the housing, and a heat sink is fixedly connected to the peripheral wall of the motor, with one end of the heat sink penetrating into the water storage tank.

[0014] Furthermore, the housing is provided with heat dissipation holes, and a fan blade is fixedly connected to the drive rod.

[0015] Furthermore, a protective cover is fixed to the outer wall of the housing.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, after the device is moved to the cutting location, the brake device of the caster wheel is first locked to ensure that the device remains stable during the cutting process. Then, the operator applies force through the gripping mechanism to smoothly push the cutting mechanism. The ball seat and the rolling ball slide in the moving groove to adjust the position and angle of the cutting blade.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific implementation examples:

[0025] like Figure 1-3As shown, a coal cutting device for coal mining includes a base 1, on which a cutting mechanism 2 is mounted. The cutting mechanism 2 is used to cut coal. The cutting mechanism 2 includes a housing 21, in which a motor 22 is fixedly installed. A drive rod 23 is fixedly connected to the output end of the motor 22. The drive rod 23 passes through and is rotatably connected to (rotatably connected via bearings) the housing 21. A cutting blade 24 is fixedly connected to one end of the drive rod 23 outside the housing 21 for cutting coal. A support frame 3 is fixedly connected to the lower part of the housing 21. A ball seat 4 is fixedly connected to the lower end of the support frame 3. The ball seat 4 has an inverted T-shaped cross-section. A moving groove 5 is provided on the base 1. The ball seat 4 slides in the moving groove 5. The lower end face of the ball seat 4... The device has a ball groove 41, in which a ball 6 rolls. The ball 6 rolls on the bottom wall of the moving groove 5. A gripping mechanism 7 is provided on the side of the housing 21 away from the cutting blade 24 for pulling the cutting mechanism 2. A caster wheel 8 is installed on the lower end face of the base 1. The caster wheel 8 is a commercially available caster wheel with a brake. After the device is moved to the cutting location, the brake device of the caster wheel 8 is locked first to ensure that the device remains stable during the cutting process. Then, the operator applies force through the gripping mechanism 7 to smoothly push the cutting mechanism 2. The ball seat 4 and the ball 6 slide in the moving groove 5 to adjust the position and angle of the cutting blade 24. This eliminates the need for workers to lift the entire device, reducing the difficulty and labor intensity of the cutting operation and improving work efficiency.

[0026] like Figure 1-3 As shown, a support frame 9 is fixedly connected to the base 1, which facilitates the movement of the base 1. The gripping mechanism 7 includes connecting arms 71 fixedly connected to the side wall of the housing 21. The connecting arms 71 have an L-shaped cross-section and can be placed on the support frame 9. A gripping rod 72 is fixedly connected between the two connecting arms 71. The cutting mechanism 2 is moved by gripping the gripping rod 72. By placing the connecting arms 71 on the support frame 9, the device can be moved simultaneously. This eliminates the need to concentrate too much attention on controlling the balance of the cutting mechanism 2, making it more convenient and less labor-intensive.

[0027] like Figure 1-3 As shown, the stand 9 is provided with a connecting mechanism 10. The connecting mechanism 10 is used to create a connecting relationship between the handle 72 and the stand 9. The connecting mechanism 10 includes two upright plates 101 fixedly connected to the stand 9. A rotating rod 102 is rotatably connected between the two upright plates 101. A connecting frame 103 is fixedly connected to the rotating rod 102. The free end of the connecting frame 103 is arc-shaped and can fit against the handle 72. After the connecting arm 71 is placed on the stand 9 and its opening is locked against the stand 9, the connecting frame 103 is rotated to fit against the handle 72. By holding the connecting frame 103 and the handle 72, the device can be pushed to move. By setting the connecting mechanism 10 to create a connecting relationship between the handle 72 and the stand 9, it is more convenient and less strenuous to push the device to move.

[0028] like Figure 1-3As shown, the moving groove 5 is connected to the side wall of the base 1. The side wall of the base 1 is detachably connected to the baffle 12 by bolts 11. By setting the baffle 12, the worker's mistaken operation is prevented from pushing the ball seat 4 and the rolling ball 6 in the cutting mechanism 2 out of the moving groove 5.

[0029] like Figure 1-3 As shown, a water storage tank 13 is fixedly connected to the inner wall of the housing 21. The water storage tank 13 is annular and a water injection pipe 14 is connected to the water storage tank 13. The water injection pipe 14 is connected to the outside of the housing 21 to add clean water to the water storage tank 13 for cooling. A heat sink 15 is fixedly connected to the peripheral wall of the motor 22. One end of the heat sink 15 extends into the water storage tank 13 to transfer the temperature of the motor 22 to the water in the water storage tank 13.

[0030] like Figure 1-3 As shown, the housing 21 has heat dissipation holes 18, and a dustproof mesh is installed inside the heat dissipation holes 18. A fan blade 16 is fixedly connected to the drive rod 23. The fan blade 16 rotates by the rotation of the drive rod 23, which causes the air inside the housing 21 to flow and the hot air to be discharged through the heat dissipation holes 18. Together with the heat sink 15 and clean water, the inside of the housing 21 and the motor 22 are cooled down.

[0031] like Figure 1-3 As shown, a protective cover 17 is fixedly connected to the outer wall of the housing 21. The protective cover 17 covers the top of the cutting blade 24 for protection.

[0032] Motor 22 is electrically connected to an external power supply and to a control unit (not shown in the figure).

[0033] The working principle of a coal cutting device in this embodiment is as follows: When in use, after moving the device to the cutting location, first lock the brake device of the universal wheel 8 to ensure that the device remains stable during the cutting process. Then, the operator applies force through the gripping mechanism 7 to smoothly push the cutting mechanism 2. The ball seat 4 and the rolling ball 6 slide in the moving groove 5 to adjust the position and angle of the cutting blade 24. In this way, the worker does not need to lift the entire device, which reduces the difficulty of cutting operation and labor intensity, and improves work efficiency.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
