[0038] See also Figures 1 to 6As shown, the present invention provides a self-propelled belt cutting machine suitable for steel wire rope conveyor belts, the self-propelled belt cutting machine suitable for steel wire rope conveyor belts comprises a main frame, a cutting device, a self-propelled device and a clamping device; the main frame comprises a support frame 22, a rack 2 fixedly connected to the upper front of the support frame 22, a slide rail fixing beam 5 fixedly connected to the lower front and rear of the support frame 22, a slide rail group 16 fixedly connected to the inner side of the slide rail fixing beam 5, a workbench support beam group 17 fixedly connected to the slide rail group 16, a cutting device fixedly connected to the rear of the workbench support beam group 17, and a self-propelled device fixedly connected to the front of the workbench support beam group 17; the cutting device comprises a cutter head guide rail 6 fixedly connected to the workbench support beam group 17, a cutter head 7 slidably connected to the cutter head guide rail 6, and a rocker 9 hinged to the top of the cutter head 7 through the first hinge mechanism 8. The crank rod 11 is fixedly connected to the rocker 9 above the first transmission shaft 10, and the crank rod 11 is fixedly connected to one side of the output shaft of the RV reducer 12, an explosion-proof motor 13 is fixedly connected to the RV reducer 12 above, and a reducer bracket 14 is fixedly connected to the RV reducer 12 below; the self-propelled device includes a groove wheel lever 1 fixedly connected to the other side of the output shaft of the RV reducer 12, a groove wheel 3 connected to the upper side in cooperation with the groove wheel lever 1, a second transmission shaft 24 fixedly connected to the groove wheel 3, a gear 4 fixedly connected to the front of the second transmission shaft 24, and a transmission shaft bracket 15 fixedly connected to the second transmission shaft 24; the clamping device includes a pressing plate 19, a second hinge mechanism 23 fixedly connected to the right side of the pressing plate 19, a knife-edge pad 21 fixedly connected to the second hinge mechanism 23, and a pressing plate fixing bolt 18 located on the left side of the pressing plate 19.

[0039] When working, firstly, the operation preparation is carried out, the steel wire rope conveyor belt to be cut is placed in the specified area, and the two ends of the conveyor belt 20 are pressed by the pressing plate 19. After the preparation work is completed, the belt cutting machine is started, and the explosion-proof motor 13 transmits the power to the crank rod 11 and the groove wheel lever 1 at the same time through the output shaft of the RV reducer 12. At this time, the crank rod 11 drives the rocker 9 to transmit the power to the guillotine head 7, so that the guillotine head 7 performs downward guillotine cutting along the cutter head guide rail 6. At this time, the groove wheel lever 1 moves at the same speed as the crank rod 11 on the other side of the output shaft of the RV reducer 12, and is in an idling state, that is, the groove wheel lever 1 has not yet moved the groove wheel 3. When the guillotine head 7 contacts the conveyor belt 20, the tip of the guillotine head 7 pierces the conveyor belt 20. The conveyor belt 20 is rubberized, and then the conveyor belt 20 is cut off by cooperating with the belt blade pad 21, and finally the shear head 7 enters the reserved notch of the belt blade pad 21 to complete the cutting action, and then starts the return journey. When the shear head 7 leaves the thickness range of the conveyor belt 20, the groove wheel lever 1 starts to shift the groove wheel 3, and the groove wheel 3 drives the second transmission shaft 24 fixedly connected to it to transmit power to the gear 4, so that the gear 4 drives the entire workbench to move to the right through the rack 2 meshing with it. When the groove wheel lever 1 leaves the groove wheel 3, the shifting work is completed, the workbench stops moving, and the crank rod 11 starts to drive the shear head 7 hinged to the rocker 9 to perform the next stage of shearing action. At this time, it is a stage-by-stage complete shearing belt process.
