[0027] Refer to Figures 4-6The quick disassembly assembly comprises a fixed block 12, a clamping block 13, a spring 14, a push rod 15, a spring 16, a sieve plate 17, a limiting block 18, a feeding box 3, a conveying pipe 4, a motor 5 and an auger blade 6. The lower surface of the fixed block 12 is fixedly connected to the outer wall of the rack 1. The clamping block 13 is rotatably connected to the inside of the fixed block 12. The spring 14 is arranged in the fixed block 12. One end of the spring 14 is fixedly connected to the inside of the fixed block 12. The push rod 15 is slidably connected to the inside of the fixed block 12. The spring 16 is arranged in the fixed block 12. One end of the spring 16 is fixedly connected to one end of the push rod 15. When the sieve plate 17 is disassembled, the clamping block 13 is pulled up to release the fixation of the sieve plate 17. The spring 16 is reset to push the push rod 15, so that the sieve plate 17 is separated from the fixed block 12. The limiting block 18 is used for auxiliary guidance. The sieve plate 17 is arranged in the inside of the rack 1. The limiting block 18 is fixedly connected to the outer wall of the rack 1. Both ends of the sieve plate 17 are arranged in the inside of the fixed block 12. The feeding box 3 is arranged on one side of the rack 1. The feeding box 3 is fixedly connected with the conveying pipe 4. The conveying pipe 4 is rotatably connected with the auger blade 6. The discharging port is arranged above the conveying pipe 4. One end of the conveying pipe 4 is provided with the motor 5. The output end of the motor 5 penetrates through the conveying pipe 4 and is fixedly connected to one end of the auger blade 6. The material in the feeding box 3 is rotated by the motor 5 driving the auger blade 6, is conveyed upwards along the conveying pipe 4 to the discharging port and is uniformly spread to the conveying belt 1 9. The sieve plate 17 plays a dual role in the process: first, the sieve plate 17 sieves out the impurities with a particle size larger than the required particle size, so as to ensure the quality of the mixture; second, the sieve plate 17 guides the sliding direction of the material through the design of the inclination angle, so as to avoid the accumulation or segregation of the material.

[0028] Working principle: when the material is fed, the material is stored in the hopper 2. The pressure sensor integrated in the conveying belt 1 9 monitors the weight of the material in real time. When the material needs to be fed, the electric telescopic rod 9 is elongated. The hinged block 10 and the connecting rod 1 1 drive the hopper cover 7 to rotate around the outer wall of the hopper 2 to open. The aggregate in the hopper 2 falls to the sieve plate 17 and then slides to the conveying belt 1 9. With the conveying of the material, when the weight detected by the pressure sensor reaches the preset value, a signal is sent to the electric telescopic rod 9 to make it contract, and the hopper cover 7 is closed.

[0029] The motor 5 drives the auger blade 6 to rotate in the conveying pipe 4, so as to convey the material in the feeding box 3 from the discharging port above the conveying pipe 4 to the conveying belt 1 9. The material is sieved by the sieve plate 17 when falling, so as to ensure that the particle size meets the requirements. When the sieve plate 17 is disassembled, the clamping block 13 is pulled up to release the fixation of the sieve plate 17. The spring 16 is reset to push the push rod 15, so that the sieve plate 17 is separated from the fixed block 12. The limiting block 18 is used for auxiliary guidance. The conveying belt 1 9 conveys the quantified material to the mixing pot 20. The conveying belt 2 1 cooperates with the mixing pot 20 to complete the subsequent operation after mixing.
