[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figure 1-4This utility model discloses an anti-clogging receiving hopper for unloading laterite nickel ore, comprising a discharge hopper 1 for facilitating the discharge of laterite nickel ore; an extension frame 2 at the upper end of the discharge hopper 1 for facilitating the loading of more laterite nickel ore; the four ends of the extension frame 2 are fixedly connected to the discharge hopper 1 by connecting bolts 3, and a clearing component is provided inside the discharge hopper 1; the clearing component includes a cross support frame 4 horizontally disposed inside the discharge hopper 1, which facilitates the installation of a servo motor 5, and the cross support frame 4 is bolted to the discharge hopper. 1. The inner wall is detachably connected; the entire assembly can be removed by loosening the bolts. A servo motor 5 is installed in the center of the top surface of the cross support bracket 4, facilitating the control of the rotating block 7. A flange 6 is fixedly connected to the bottom surface of the output shaft of the servo motor 5, allowing easy connection to the rotating block 7. The rotating block 7 is fixedly connected to the bottom surface of the flange 6, facilitating the installation of the crushing roller 8. Multiple equidistant crushing rollers 8 are horizontally fixed to the outer side of the rotating block 7, facilitating the crushing of laterite nickel ore. The crushing rollers 8 are located in the upper middle part of the discharge hopper 1. The radial length of the section is two-thirds of the inner diameter of the corresponding position of the discharge hopper 1. The spacing between adjacent crushing rollers 8 is relatively large to ensure that the laterite nickel ore can fall smoothly from the gap between the rollers after crushing, avoiding blockage caused by the structure occupying space. A connecting rod 9 is fixedly connected to the middle of the bottom surface of the rotating block 7, which facilitates the rotation of the drive bevel gear 10. The lower end of the connecting rod 9 is fixedly connected to the drive bevel gear 10, which facilitates the rotation of the driven bevel gear 11. A transmission box 16 is provided at the lower end of the connecting rod 9 to prevent the laterite nickel ore from falling into the mud. Nickel ore jams the driving bevel gear 10 and the driven bevel gear 11; the transmission box 16 is fixedly connected to the lower end of the discharge hopper 1, and the transmission roller 12 is rotatably connected inside the transmission box 16. The driven sleeve 13 can be rotated through the transmission roller 12. The two ends of the transmission roller 12 are provided with detachable bearing covers at the rotatable connection points with the inner wall of the discharge hopper 1. After disassembly, the transmission roller 12, sleeve 13, and evacuation plate 14 can be pulled out as a whole; the driven bevel gear 11 is fixedly connected to the outside of the transmission roller 12, and the driven bevel gear 11 meshes with the driving bevel gear 10 for transmission.

[0015] In this invention, the two ends of the drive roller 12 are rotatably connected to the inner wall of the discharge hopper 1, and both ends of the drive roller 12 are fixedly connected to sleeves 13, which facilitate the installation of the evacuation plates 14. Multiple equidistant evacuation plates 14 are fixedly connected to the outer side of the sleeves 13, which facilitate the unblocking of laterite nickel ore. The evacuation plates 14 are only distributed at the lower end of the drive roller 12 near the discharge port, and their length is three-quarters of the lower inner diameter of the discharge hopper 1. The included angle between adjacent evacuation plates 14 is 60°, ensuring proper drainage of the discharge port. The guide plate 14 has a guiding function without obstructing the main material from falling. The guide holes on the surface of the evacuation plate 14 can reduce the adhesion area of ​​laterite nickel ore. Combined with the gap between the cross support frame 4 and the inner wall of the discharge hopper 1, it is easy to use a high-pressure water gun to reach in from the extension frame 2 to wash the internal structure. The surface of the evacuation plate 14 has multiple equidistant guide holes. A baffle 15 is fixed to the middle of the top surface of the cross support frame 4 to prevent laterite nickel ore from clogging the servo motor 5. The bottom surface of the baffle 15 has an installation groove, and the servo motor 5 is installed in the installation groove.

[0016] Working principle: In the preparation stage of using this utility model, it is necessary to check whether the hopper 1 and the extension frame 2 are firmly fixed by the connecting bolts 3, and ensure that the cross support frame 4 is stably connected to the inner wall of the hopper 1 by the bolts. Then, install the servo motor 5 in the mounting groove on the bottom surface of the baffle 15 in the middle of the top surface of the cross support frame 4, and fix the rotating block 7 to the bottom surface of the output shaft of the servo motor 5 through the flange 6 to complete the equipment assembly. When starting and feeding, connect the wires of the servo motor 5 and turn on the power. Pour the laterite nickel ore into the hopper 1 through the extension frame 2 and start the servo motor 5. Then, the upper crushing operation begins, and the output shaft of the servo motor 5 rotates. Flange 6 drives the rotating block 7 to rotate synchronously. Multiple equidistant crushing rollers 8 (located in the upper part of the discharge hopper 1, with a radial length of two-thirds of the corresponding inner diameter and a large adjacent spacing) are horizontally fixed to the outer side of the rotating block 7 and rotate horizontally with the rotating block 7 to crush the adhering and agglomerated parts of the poured laterite nickel ore. The crushed material falls through the gaps between the crushing rollers 8 to avoid blockage at the top. At the same time, the baffle 15 on the top surface of the cross support frame 4 prevents the laterite nickel ore from directly contacting the servo motor 5 to prevent the motor from being blocked. Next is the lower unblocking operation. When the rotating block 7 rotates, the connecting rod 9 fixed to the middle of its bottom surface rotates synchronously, driving the drive bevel gear 1 fixed at the lower end. The drive roller 12 rotates within the transmission box 16 (the transmission box 16 is fixed to the lower end of the discharge hopper 1 to prevent laterite nickel ore from jamming the gears), driving the bevel gear 10 to mesh with the driven bevel gear 11 fixed to the outside of the transmission roller 12, thus driving the transmission roller 12 to rotate on the inner wall of the discharge hopper 1 (removable bearing covers are provided at the rotating connection at both ends). The sleeves 13 fixed to both ends of the transmission roller 12 rotate with it, and multiple evacuation plates 14 fixed to the outside of the sleeves 13 (distributed only at the lower end of the transmission roller 12 near the discharge port, with a length of three-quarters of the lower inner diameter of the discharge hopper 1 and an adjacent included angle of 60°) rotate synchronously, clearing any laterite nickel ore that may be blocking the lower part of the discharge hopper 1. The guide holes on the surface of the evacuation plate 14 reduce the adhesion area of ​​laterite nickel ore, further improving the dredging efficiency. After the material is discharged, the servo motor 5 is turned off. If cleaning is required, a high-pressure water gun can be inserted from the extension frame 2 through the gap between the cross support frame 4 and the inner wall of the discharge hopper 1 to rinse the inside of the discharge hopper 1 and components such as the crushing roller 8 and the evacuation plate 14. If maintenance is required, the connecting bolts between the cross support frame 4 and the inner wall of the discharge hopper 1 can be loosened, and the cross support frame 4, servo motor 5, etc. can be taken out as a whole. The bearing covers at both ends of the transmission roller 12 can be removed, and the transmission roller 12, sleeve 13, and evacuation plate 14 can be pulled out as a whole for easy maintenance or replacement of components.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
