[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0026] like Figure 1-Figure 3 As shown, in one embodiment, a slitter integrated shaft is used in a slitter hopper 5. For the convenience of subsequent description, the structure of the slitter hopper 5 is first described. Figure 1 The entire hopper includes a front side plate, a rear side plate, a left side plate and a right side plate, and the integrated shaft is inside the hopper. The integrated shaft includes a main shaft 1, and the two ends of the main shaft 1 are respectively movably connected to the left side plate and the right side of the hopper, so that the main shaft 1 can rotate in the hopper. It should be noted that how the main shaft 1 is connected to the left side plate and the right side plate of the hopper is a prior art and will not be described in detail in this application;

[0027] There are multiple spiral material pressing structures distributed on the outside of the integrated shaft. The material leveling structure 2 is composed of at least two spiral rods assembled around the main shaft 1. The left and right ends of the material leveling structure 2 have the same structure or the same shape but different sizes. It is fixedly connected to the main shaft 1 through a connecting rod 3. Preferably, the connection method is welding. The variable frequency reduction motor drives the main shaft 1 to rotate, and the main shaft 1 drives the spiral material pressing structure to rotate. The variable frequency reduction motor has forward and reverse rotation functions. When the motor rotates forward, the main shaft 1 drives the material leveling structure 2 to rotate. The material leveling structure 2 and the front and rear side plates of the hopper form an extrusion and pushing effect on the material in the mud bucket, causing the material to move horizontally to the right; and when the motor reverses, the material moves horizontally to the left, achieving the effect of distributing materials in the left and right directions.

[0028] There are multiple arch-breaking and downward-pressing blades 4 evenly distributed on the outside of the main shaft 1, which form an angle with the main shaft 1 in the horizontal direction. When the motor rotates forward, the arch-breaking and downward-pressing blades 4 produce a horizontal rightward force component and a vertical downward force component on the material in the hopper, and simultaneously realize the two functions of horizontal pushing and vertical downward pressing. Since the arch-breaking blades 4 form a certain angle with the horizontal direction, coupled with the rotational motion, the blades 4 and the side walls of the hopper together produce an arch-breaking function on the material.

[0029] In summary, the above technical solution can realize the three functions of horizontal material distribution, material arch breaking and vertical downward pressing, and has a simple structure, a long service life and a low investment cost. In addition, the material leveling structure 2, the blades 4 and the main shaft 1 are all made of metal materials.

[0030] Furthermore, as for the connection method of the three, the main shaft 1, the material leveling structure 2 and the blades 4 are welded into an integrated structure, so that the overall structural strength is higher and the service life is extended. Among them, the blades 4 and the main shaft 1 form a certain angle in the horizontal direction, such as 35°-55°, so that the surrounding sludge can be exerted with horizontal rightward and vertical downward pressure. Two adjacent blades 4 are evenly arranged at an angle of 45° along the circumferential direction of the main shaft 1.

[0031] Furthermore, the height of the blade 4 is the same as the distance from the material leveling structure 2 to the surface of the main shaft 1. For details, please refer to Figure 2-Figure 3 , so that the blades 4 can not only break the sludge, but also serve as a connecting unit, and can also improve the connection strength between the material leveling structure 2 and the main shaft 1. As for the blades 4 themselves, the blades 4 are block-shaped structures, and their edges are sharp to a certain extent, so as to cut and break the sludge. In addition, there are multiple groups of arch-breaking and pressing blades 4 evenly distributed along the axial direction of the main shaft 1, and each group of arch-breaking and pressing blades 4 includes 6-8 evenly distributed blades 4.

[0032] Furthermore, the connecting rod 3 has a certain inclination angle, and can also cut the sludge when rotating together with the material leveling structure 2, thereby comprehensively improving the cutting and pressing effect on the sludge.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
