[0020] The present invention has the following beneficial effects:

[0021] 1. The present invention links the corresponding composite processing box, cleaning pipe, water pump and main conveying pipe with the feeding component. In the process of conveying the ore to be crushed, the cleaning pipe receives the clean water pumped by the water pump through the main conveying pipe and sprays it to the ore to be crushed conveyed by the feeding component, thereby removing the mud covering the surface of the ore to be crushed, ensuring the meshing crushing efficiency of the subsequent two crushing rollers on the ore to be crushed, and relatively reducing the wear speed of the two crushing rollers, thereby solving the problems existing in the prior art.

[0023] 3. The present invention filters the wastewater flowing into the composite treatment box and provides channel conditions for recycling and reuse by a water pump through the filter assembly and the third connecting valve pipe, thereby meeting the wastewater recycling effect and reducing the use cost.

[0024] 4. The present invention arranges a plurality of linkage buffer assemblies inside each of the two crushing rollers. After receiving the vibration energy of the corresponding crushing roller, the T-shaped rod inside the subsequent linkage buffer assembly will push the damping plug inside the H-shaped cylinder for damping buffering, and the corresponding reset spring will provide power energy for the reciprocating movement of the T-shaped rod and the damping plug, thereby realizing the effect of reciprocating damping buffering. When cooling water is transported to the inside of the two crushing rollers, the inside of the H-shaped cylinder will synchronously receive the cooling water. Therefore, during the displacement process of the corresponding T-shaped rod and the damping plug, the damping plug will produce a hydraulic ejection energy dissipation effect inside the H-shaped cylinder, and further linkage damping buffering will perform double buffering on the two crushing rollers, thereby fully ensuring the stability of the two crushing rollers during the meshing operation.

[0025] 5. The present invention automatically conveys the crushed mineral material through the second conveyor belt, and the residual moisture inside the crushed mineral material will gradually flow through the second transition filter under the influence of gravity during the long-term transportation process and converge to the top of the guide cone tube at the bottom of the extension frame, and then converge to the designated collection container through the guide cone tube. The mixed solution collected in the collection container also contains a large amount of mineral powder and still has recycling value. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] In a specific embodiment, when vibration is generated during the operation of the two crushing rollers 3 meshing with each other, the multiple linkage buffer components 22 arranged inside the two crushing rollers 3 can play a buffering effect, specifically:

[0055] After receiving the vibration energy of the corresponding crushing roller 3, the T-shaped rod 222 will push the damping plug 223 inside the H-shaped cylinder 221 to perform damping and buffering, and the corresponding return spring 224 will provide power energy for the reciprocating movement of the T-shaped rod 222 and the damping plug 223, thereby achieving the effect of reciprocating damping and buffering;

[0056] When cooling water is transported to the inside of the two crushing rollers 3, the inside of the H-type cylinder 221 will receive the cooling water synchronously. Therefore, during the displacement of the corresponding T-shaped rod 222 and the damping plug 223, the damping plug 223 will produce a hydraulic ejection energy dissipation effect inside the H-type cylinder 221, and then the damping buffer will be linked to perform double buffering on the crushing rollers 3, fully ensuring the stability of the two crushing rollers 3 during the meshing operation.

[0059] The inner wall of the second conveyor belt 181 is provided with a plurality of through-shaped auxiliary grooves, in which the second transition filter 19 is nested. The second transition filter 19 is used to provide filtering space, and then in the subsequent automatic feeding process of the second conveyor belt 181, the water content of the crushed ore is controlled by gravity to reduce the water content inside the crushed ore, thereby creating processing conditions conducive to the next process. The surface of the second transition filter 19 is coplanar with the surface of the second conveyor belt 181 to avoid structural interference. The bottom of the extension frame 17 is provided with a guide cone 23 to centrally collect and transport the water controlled by gravity from the crushed ore.

[0060] In a specific embodiment: for the crushed ore outputted from the crushing box 1, the third servo motor 182 is started, and the output end of the third servo motor 182 drives the corresponding second transmission shaft and drives the second conveyor belt 181 to circulate with the support of another second transmission shaft and the extension frame 17, and then the second conveyor belt 181 drives the crushed ore to be actively and long-distance transported;

[0061] During the feeding process of the second conveyor belt 181, the residual moisture inside the crushed mineral material will be affected by gravity during the long period of transportation and gradually flow through the second transition filter 19 to gather into the top of the guide cone 23 set at the bottom of the extension frame 17, and then converge into the designated collection container through the guide cone 23. The mixed solution collected in the collection container also contains a large amount of mineral powder, which still has recycling value.
