[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] Embodiment 1:

[0020] The following is combined with Figure 1-3The present embodiment describes a brick cutting device for making bricks from coal gangue, comprising: a conveyor belt drive 1, two sets of conveyor belt drives 1 are provided with a gap along the conveying direction, the roller ends of the two sets of conveyor belt drives 1 are both rotatably connected to the bracket 2, a mud blank extruder 3 is provided on the upper part of the first end conveyor belt drive 1, the bracket 2 at the gap between the two sets of conveyor belt drives 1 is connected to a blank cutting bracket 4, a steel wire rack 5 is slidably connected in the blank cutting bracket 4, a plurality of vertical steel wires 6 and a horizontal steel wire 7 are connected in the steel wire rack 5, the vertical steel wire 6 and the horizontal steel wire 7 are located in the gap between the two sets of conveyor belt drives 1, and the steel wire rack 5 slides in the blank cutting bracket 4 through a lifting mechanism 8;

[0021] The mud extruder 3 extrude the mud onto the first group of conveyor belt drives 1, which are then transported by the conveyor belt drives 1 to the gap between the two groups of conveyor belt drives 1. The lifting mechanism 8 drives the wire rack 5 to intermittently reciprocate. When the wire rack 5 is stationary, the vertical steel wire 6 of the wire rack 5 cuts the mud into mud strips, and the horizontal steel wire 7 does not contact the mud strips. When the wire rack 5 slides, the movement is very fast. The wire rack 5 drives the horizontal steel wire 7 to move quickly to cut the mud strips and cut the mud strips into bricks. The faster the wire rack 5 moves, the straighter the cut bricks are, and the continuous cutting of the mud is completed without stopping or changing the knife for cutting.

[0022] The lifting mechanism 8 includes a hydraulic support 81, which is connected to the upper surface of the cutting support 4, and the lower surface of the top wall of the hydraulic support 81 is connected to the fixed end of the cylinder 82, and the telescopic end of the cylinder 82 is connected to the wire frame 5;

[0023] The extension and retraction of the steel wire frame 5 is controlled by the extension and retraction of the cylinder 82, so that the steel wire frame 5 is controlled to respond and move at the fastest speed, and the quality of the bricks is higher.

[0024] The conveyor belt drive 1 is composed of four rollers 9 and a conveyor belt 10. The inner surface of the conveyor belt 10 is in contact with a support frame 11, and the support frame 11 is connected to the bracket 2;

[0025] The conveyor belt drive 1 formed by the cooperation of the four rollers 9 and the conveyor belt 10 makes the free space between the two sets of conveyor belt drives 1 smaller, and the bricks are supported stably without being dented or deformed.

[0026] A wheel groove 12 is provided on the side wall of the blank cutting bracket 4, a rotating wheel 13 is rotatably connected in the wheel groove 12, the rotating wheel 13 is in contact with the wire frame 5, and a reflective sheet 14 is evenly distributed on the surface of the rotating wheel 13. An infrared light transmitting and receiving device 15 can transmit infrared light to the reflective sheet 14 and receive reflected infrared light. The controller can control the power speed of the conveyor belt drive 1 according to whether the received infrared light fluctuates;

[0027] When the wire rack 5 moves, it drives the contacting rotating wheel 13 to rotate, and the rotating wheel 13 drives the reflective sheet 14 to rotate. The infrared light transmitting and receiving device 15 can transmit infrared light to the reflective sheet 14 and receive the reflected infrared light. The received light signal is sent to the controller. When the rotating wheel 13 does not rotate, the light signal only keeps reflecting or not reflecting the turntable. The controller controls the conveyor belt drive 1 to rotate at a uniform speed. When the light signal fluctuates between reflection and being on the verge of retirement and not being reflected, the controller controls the conveyor belt drive 1 to slow down and rotate, so as to achieve a better cutting effect.
