The threaded lifting component is used to drive the corresponding U-shaped slide 5 to move up and down. The two U-shaped slides 5 are used to drive the two belt-pressing rollers 1 to move up and down through the rotating shaft 2. When the two belt-pressing rollers 1 move downward, the conveyor belt is squeezed downward at the tail car conveyor belt of the external stacker so that it is pressed downward into a groove in the middle, which can effectively prevent the conveyor belt from overflowing from both sides at the tail car when conveying mud and water.

[0024] Specifically, the joint drive rotation assembly includes a linkage rod 9, and worms are installed at both ends of the linkage rod 9, wherein both ends of the linkage rod 9 are fixedly connected with couplings 14, and the repelling ends of the two couplings 14 are respectively fixedly connected to the ends close to the two worms, and the provided couplings 14 are used for the stable connection between the corresponding worms and the linkage rod 9 to prevent the phenomenon of collapse during rotation caused by different axes due to slight deviations. The two worms are rotatably installed on the front sides of the corresponding triangular supports, wherein the front sides of the triangular supports are fixedly installed with a first bearing seat 3, and a first support bearing is fixedly installed in the first bearing seat 3, and the inner ring of the first support bearing is fixedly fitted with the outer side of the corresponding worm.

[0025] Furthermore, the threaded lifting assembly includes a screw rod 10 rotatably mounted on the inner wall of the bottom of the corresponding rectangular groove, wherein a third support bearing is fixedly connected to the inner wall of the bottom of the rectangular groove, and the inner side of the inner ring of the third support bearing is fixedly connected to the outer bottom of the corresponding screw rod 10, so as to achieve the effect of rotatably mounting the screw rod 10, and the top of the screw rod 10 extends to the top of the corresponding support rod 4 and is fixedly connected to the bottom of the worm gear, and a nut 11 is threadedly sleeved on the screw rod 10, and a connecting plate 12 is fixedly connected to the rear side of the nut 11, and the front side of the connecting plate 12 is fixedly connected to the rear side of the corresponding U-shaped slide 5, and the front side of the connecting plate 12 is in sliding contact with the rear side of the corresponding support rod 4; the screw rod 10, nut 11 and connecting plate 12 are arranged to cooperate, and the two rotating worm gears are used to drive the two screw rods 10 to rotate synchronously, and the two screw rods 10 rotate to drive the two nuts 11 to move up and down, and the two nuts 11 are used to drive the two U-shaped slides 5 to move up and down synchronously through the two connecting plates 12.

[0026] The method of using this embodiment is as follows: the device is installed on the tail car cross beam 7 of the tail car conveyor belt of the stacker, so that it is located at the transition section from the ground conveyor belt to the tail car, and the two belt pressure wheels 1 are located in the middle of the upper part of the conveyor belt. When the conveyor belt conveys muddy and watery materials, the muddy and watery materials may be flattened due to the transition section from the ground conveyor belt to the tail car, which may easily cause the muddy and watery materials to overflow from both sides. The personnel can start the driving motor 6 in the positive direction to drive the left worm to rotate, and the left worm drives the linkage rod 9 to rotate through the left coupling 14, and the linkage rod 9 drives the right worm to rotate synchronously through the right coupling 14. Under the meshing action of the worm and the corresponding worm wheel, the two worms drive the two worm wheels to rotate synchronously. At this time, the two turbines drive the two screw rods 10 to rotate synchronously, and the rotation of the two screw rods 10 drives the two nuts 11 to move downward synchronously. The two nuts 11 drive the two U-shaped slides 5 to slide downward on the corresponding support rods 4 through the two connecting plates 12. The two U-shaped slides 5 drive the two belt-pressing rollers 1 to move downward through the rotating shaft 2. When the two belt-pressing rollers 1 move downward, the middle of the conveyor belt is pressed downward to form a groove in the middle, which can effectively avoid the phenomenon of overflow from both sides of the tail car part when the conveyor belt transports mud and water, facilitate the normal entry of mud and water into the tail car hopper, avoid the phenomenon of difficulty in cleaning materials and production stoppage caused by the overflow of mud and water, reduce manpower and material costs, reduce stoppage time, and improve work efficiency;

[0027] In addition, by means of the rotational installation of the rotating shaft 2 and the U-shaped slide 5, the friction can drive the pressure roller 1 to rotate when the conveyor belt moves, and the pressure roller 1 drives the rotating shaft 2 to rotate. By utilizing the rotation of the pressure roller 1, it is possible to avoid the phenomenon of large friction with the conveyor belt, thereby ensuring the stability of use. When normal material conveying does not require belt pressing, the drive motor 6 is started in the reverse direction. Similarly, the movement direction of the drive motor 6 is completely opposite to the above-mentioned forward start. At this time, the two pressure rollers 1 move back upward to release the downward pressure on the conveyor belt, and then the normal material conveying work can be carried out to prevent the normal material conveying work from being affected.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
