Detailed ways

The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

As shown in Figures 1-4, the high-safety coal cutting structure provided by this embodiment includes a first support plate 1, a second support plate 2 and a cutting knife structure 3, and the first support plate 1 and the second support The inner surface of the plate 2 is respectively vertically provided with a chute 4 and an auxiliary chute 5;

The upper end surface of the first support plate 1 is provided with a drive motor 6, the output end of the drive motor 6 penetrates into the inside of the chute 4 and is connected with a screw 7, and the forward rotation and reverse rotation of the drive motor 6 are used to drive the screw 7 to rotate forward and reverse; thereby driving the cutting knife structure 3 to slide up and down; the driving motor 6 is a slow motor structure, and the speed of the slow motor is relatively slow, which can ensure the stability of the cutting knife structure 3 when sliding up and down; the auxiliary sliding The block 11 slides in the auxiliary chute 5, and the slider 10 slides in the chute 4. The slider 10 is provided with a threaded hole 16, and the screw rod 7 passes through the threaded hole 16 and extends to the bottom of the chute 4;

The cutting knife structure 3 includes a sliding body 8 and a cutting blade 9, the cutting blade 9 is arranged on the lower end surface of the sliding body 8, the two sides of the sliding body 8 are respectively provided with a sliding block 10 and an auxiliary sliding block 11, the screw mandrel 7 and the sliding block 10 thread screw connection, through the rotation of the screw rod 7 inside the slider 10, the slider 10 is driven to slide in the chute 4, thereby realizing the up and down sliding adjustment of the cutting knife structure 3;

The front end surface and the rear end surface of the sliding body 8 are all slidably provided with a semi-enclosed protection box 12, the front end surface and the rear end surface of the sliding body 8 are all vertically provided with a second chute 13, and the inner surface of the semi-enclosed protection box 12 is provided with a The second sliding block 14 that is slidably connected to the second chute 13, the lower end surface of the second sliding block 14 is attached to the lower end surface of the second chute 13, and the upper end surface of the second sliding block 14 is connected to the upper end surface of the second chute 13. A compression spring 15 is arranged between them; the lower end surface of the cutting blade 9 is flush with the lower end surface of the semi-closed protective box 12, and the two semi-closed protective boxes 12 wrap the cutting blade 9, which can ensure that the cutting blade 9 is always in two positions when cutting. The interior of the semi-enclosed protective box 12 arranged symmetrically always has a good protective effect.

Further, both sides inside the second chute 13 are provided with a positioning chute 17, and both sides of the second slider 14 are provided with a positioning slider 18 that is slidably connected to the positioning chute 17, and the positioning chute 17 is connected with the positioning chute.

Furthermore, the semi-enclosed protection box 12 is a transparent acrylic plate structure, and the semi-enclosed protection box 12 provided by the transparent acrylic plate is convenient for observing the use and wear of the internal cutting blade 9, and cleaning is performed in time after use.

As shown in Figures 1-4, the principle of the high-safety coal cutting structure provided by this embodiment is as follows: when cutting the coal body, the screw mandrel 7 is driven in the threaded hole 16 by the opening of the driving motor 6 Rotate, thereby driving the slider 10 to slide up and down in the chute 4, so that the sliding body 8 slides downward between the first support plate 1 and the second support plate 2, and drives the cutting blade 9 to cut the coal body. When cutting, the lower end surfaces of the two semi-enclosed protection boxes 12 will also be in contact with the coal body. As the cutting blade 9 continues to press down and cut, the two semi-enclosed protection boxes 12 will be lifted up simultaneously. When the closed protective box 12 slides upwards, it drives the second slider 14 to slide in the second chute 13, and the compression spring 15 will also shrink thereupon at this time, thereby ensuring that the cutting blade 9 is always in two symmetrical positions when cutting. The inside of the semi-enclosed protection box 12 always has a good protection effect. When the coal body is cut, the cutting knife structure 3 rises, and the rebound setting of the compression spring 15 will make the two semi-enclosed protection boxes 12 reset, so as not to affect Protective effect when cutting next time.
