[0002] When a compound fertilizer production line is in operation, a feeding device is needed for fixed-point feeding. The commonly used feeding device is the feeding hopper. For example, there is a feeding device for compound fertilizer processing in the prior art, which has the publication number CN218370615U. In use, the hopper wall is threadedly connected to the hopper frame using threaded fasteners. The protective cover is threadedly connected to the hopper frame through connecting seats and connecting plates, respectively, using single-headed fasteners and hexagonal bolts to fix the protective cover. The four protective covers are located on the four sides of the hopper wall. After the compound fertilizer is fed, a servo motor drives the rotating shaft to rotate, which in turn drives the rotating arm to rotate. When the rotating arm rotates, it relies on a hammer to hit the hopper wall, causing the hopper wall to shake, thereby causing the material attached to the inner wall to fall, improving material utilization and avoiding waste.

[0003] Existing technology uses a servo motor to drive the rotating arm to rotate, and relies on a hammer to impact the hopper wall, causing the hopper wall to shake, thereby causing the material attached to the inner wall to fall. Repeated hammering of the hopper surface may cause physical damage to the hopper, especially when the hammering force is too large or the hammering frequency is too high. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4 As shown, an automatic feeding and conveying device for a compound fertilizer production line includes a hopper 1 with a rotating body. A connecting ring 12 is rotatably connected to the top of the hopper 1, and a retaining ring 11 is rotatably connected to the bottom of the hopper 1. The connecting ring 12 and the retaining ring 11 rotate at the same speed, and a scraper 3 is detachably installed between the connecting ring 12 and the retaining ring 11 and slidably connected to the inner wall of the hopper 1. By utilizing the synchronous rotation of the connecting ring 12 and the retaining ring 11, the scraper 3 installed between them can revolve along the inside of the hopper 1, cleaning the inner wall of the hopper 1 during the revolution. A slot 14 is opened on one side of the top of the retaining ring 11. The bottom of the scraper 3 is inserted into the inner wall of the slot 14, and the top of the scraper 3 is engaged with the inner wall of the connecting ring 12. A pin 13 is threaded through the inner wall of the connecting ring 12 and threadedly connected to the top of the scraper 3. When disassembling and assembling the scraper 3, the pin 13 on the connecting ring 12 is removed first, and then the scraper 3 can be pulled out directly by inserting it into the slot 14.

[0024] An upper bracket 2, fitted onto the upper part of the outer wall of the hopper 1, is fixedly installed on the outer side of the connecting ring 12. A lower bracket 6, fitted onto the lower part of the outer wall of the hopper 1, is fixedly installed on the outer wall of the retaining ring 11. Gear rings 4, fitted onto the inner and outer walls of the hopper 1, are fixedly installed on the surfaces of both the upper bracket 2 and the lower bracket 6 near the middle of the outer wall of the hopper 1. By driving the two gear rings 4 to rotate synchronously, the connecting ring 12 and the retaining ring 11 can rotate at the same speed under the connection of the corresponding upper bracket 2 and lower bracket 6. The gear rings 4 are rotatably connected to the outer wall of the hopper 1, and the two gear rings 4 rotate at the same speed. A fixing ring 5 is fixedly installed at the middle of the outer wall of the hopper 1. A dual-axis motor 9 is fixedly installed through the surface of the fixed ring 5. Both main shafts of the dual-axis motor 9 are fixedly equipped with spur gears 10. The two spur gears 10 are respectively meshed with the two toothed rings 4. The dual-axis motor 9 drives the upper and lower spur gears 10 to rotate at the same speed. By meshing with the corresponding toothed rings 4, the two toothed rings 4 can be rotated at the same speed and in the same direction. The upper bracket 2 and the lower bracket 6 are rotatably connected to the outer wall of the hopper 1 at opposite ends. An assembly plate 8 is fixedly installed on the outer side of the fixed ring 5. The assembly plate 8 is clearance-fitted with the outer side of the two toothed rings 4. The assembly plate 8 is used to conveniently fix the hopper 1 on the compound fertilizer production line.

The top of the retaining ring 11 extends inward and is rotatably connected to the valve port of the discharge valve 7. The discharge valve 7 will not affect the rotation of the retaining ring 11, and the discharge valve 7 can be used to conveniently control the material discharge from the hopper 1. In addition, the discharge valve 7 provided in this solution can be a common electromagnetic switch valve or gate valve on the market.

[0026] The bottom end of the retaining ring 11 is fitted onto the bottom end of the hopper 1 and is rotatably connected to the bottom end of the outer wall of the hopper 1, so as to ensure that the position of the retaining ring 11 is fixed, that is, to ensure that the retaining ring 11 can only rotate below the hopper 1.

[0027] The method of using this utility model is as follows: Start the dual-shaft motor 9. The two main shafts of the dual-shaft motor 9 drive the two spur gears 10 to rotate. The two spur gears 10 mesh with the gear rings 4 on the upper bracket 2 and the lower bracket 6 respectively, so that the gear rings 4 rotate at the same speed and in the same direction. The gear rings 4 drive the connecting ring 12 and the retaining ring 11 to rotate at the same speed through the upper bracket 2 and the lower bracket 6 respectively. When the connecting ring 12 and the retaining ring 11 rotate at the same speed, the scraper 3 slides along the inner wall of the hopper 1, thereby cleaning the inner wall of the hopper 1.

[0028] The wiring diagrams of the dual-axis motor 9 and the unloading valve 7 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the dual-axis motor 9 and the unloading valve 7 will not be explained in detail.
