A pressure sensor 7 is provided at the bottom of the metal iron sheet 22. The metal iron sheet 22 has good electrical conductivity and magnetic conductivity. When Chinese medicinal materials pass through the upper conveyor belt 32, the pressure causes the metal iron sheet 22 to produce a slight deformation or the physical quantities such as the magnetic field between it and the pressure sensor 7 change, which can more effectively transmit the pressure signal to the pressure sensor 7 below. The bottom discharge port of the storage hopper 2 is clamped and installed with a spiral stirring knife 24. The spiral stirring knife 24 is provided at the discharge port to promote material discharge, prevent blockage, mix materials, and control the discharge speed.

[0027] The feeding end of the vibrating screen 3 is connected to a wind assembly for wind screening of Chinese medicine materials. The wind assembly includes a box 25, a first fan 26, an air inlet pipe 27 and a first air outlet pipe 28. A dust collecting chamber 29 is installed inside the box 25.

One end of the lower conveyor belt 33 extends to the interior of the box body 25, and the bottom of the blowing pipe 30 corresponds to the surface of the lower conveyor belt 33.

[0028] A cleaning component for cleaning material residues is installed on the outside of the storage hopper 2, and one end of the cleaning component extends to the interior of the storage hopper 2. The cleaning component includes a second fan 8, a second air outlet pipe 9, a blowing plate 10 and a fixed block 21, and is installed on the outside of the storage hopper 2 through the fixed block 21. The fixed block 21 can be used to support and place the second fan 8.

[0029] One end of the second air outlet pipe 9 is connected to the output end of the second fan 8. A sealing cover plate 20 is arranged above the storage hopper 2. The sealing cover plate 20 can protect the Chinese medicine material from falling into dust and impurities. The sealing cover plate 20 is hollow in design. The blowing plate 10 is installed on the inner wall of the sealing cover plate 20. The other end of the second air outlet pipe 9 passes through the sealing cover plate 20 and corresponds to the top of the blowing plate 10. The second air outlet pipe 9 is a detachable hose. The sealing cover plate 20 can be opened when the Chinese medicine material enters the storage hopper 2.

[0030] A collecting assembly for collecting and discharging material residues is installed below the storage hopper 2, and the collecting assembly includes a chip collecting hopper 31, an electric slide bar 12 and a connecting frame 13. The chip collecting hopper 31 is arranged on the top of the upper conveyor belt 32. By setting the chip collecting hopper 31, the material residues in the storage hopper 2 can be collected. The discharge port material of the storage hopper 2 is a permanent magnet, and a soft magnetic material is arranged at the corresponding position of the chip collecting hopper 31. A support plate 14 is arranged at the bottom of the lower conveyor belt 33, and grooves 15 are provided on both sides of the outside of the support plate 14. The groove 15 is used to place the electric slide bar 12, and the electric slide bar 12 is adapted to be arranged and is located inside the groove 15. One end of the connecting frame 13 is connected to the electric slide bar 12, and the other end of the connecting frame 13 is fixedly connected to one side of the chip collecting hopper 31.

[0031] A support frame 16 is provided outside the storage hopper 2, a controller 17 is installed on the top of the support frame 16, a gas sensor 19 is installed inside the storage hopper 2, and the controller 17 is electrically connected to the pressure sensor 7 and the gas sensor 19 respectively. The controller 17 is the core management unit of the entire system, and the signals of the gas sensor 19 and the pressure sensor 7 are received through the controller 17.

[0032] First, open the sealing cover 20, and load the Chinese medicine material to be processed into the storage hopper 2 through the feed port at the top of the storage hopper 2. The Chinese medicine material will fall to the discharge port at the bottom of the storage hopper 2 due to gravity. The Chinese medicine material is accumulated at the discharge port due to the blockage of the baffle 4. The gas sensor 19 detects that the Chinese medicine material is not moldy or damp, and transmits the signal to the controller 17. The controller 17 receives the signal and sends an instruction to the electric push rod 5 and the spiral stirring knife 24. The spiral stirring knife 24 rotates to promote material flow and prevent blockage. The electric push rod 5 drives the baffle 4 to move, and the baffle 4 moves away from the discharge port. The Chinese medicine material falls due to gravity. When the Chinese medicine material falls on the upper conveyor belt 32, the weight of the Chinese medicine material is transmitted to the metal iron sheet 22 through the upper conveyor belt 32. The metal iron sheet 22 then transmits the pressure to the pressure sensor 7 below. The pressure sensor 7 converts the pressure signal it feels into an electrical signal and transmits it to the controller 17. The controller 17 analyzes and processes the electrical signal to calculate the current weight of the Chinese medicine material. When the weight of the Chinese medicine material reaches a preset quantity When the value is reached, the controller 17 sends a control signal, and the electric push rod 5 resets the baffle 4 to stop unloading, thereby realizing quantitative transportation of the material. Then the Chinese medicine material enters the box body 25 through the upper conveyor belt 32. Due to the upper and lower distribution height difference between the upper conveyor belt 32 and the lower conveyor belt 33, the upper conveyor belt 32 moves and drops the material onto the surface of the lower conveyor belt 33. When the material enters the box body 25, the first fan 26 is started. Since the air inlet pipe 27 is inside the dust collecting chamber 29, a suction effect is generated, and the blowing effect generated by the first air outlet pipe 28 forms a directional air flow circulation inside the box body 25. During this air flow circulation process, the residues and debris of the Chinese medicine material are greatly affected by the air flow due to their light weight and irregular shape, and will enter the dust collecting chamber 29 under the drive of the air flow. At the same time, the qualified Chinese medicine material is relatively less affected by the air flow due to its own physical properties, and can be kept on the lower conveyor belt 33. The lower conveyor belt 33 continues to move. Due to gravity, the Chinese medicine material enters the feeding port of the vibrating screen 3 for secondary screening, and finally the qualified Chinese medicine material is discharged.

[0033] When the storage hopper 2 needs to be cleaned, the second fan 8 is turned on, and the wind is blown evenly from the second air outlet pipe 9 to the inner wall of the storage hopper 2 through the blowing plate 10. The electric push rod 5 moves to remove the baffle 4, and the electric slide bar 12 is started to drive the connecting frame 13 to move, and the chip collecting bucket 31 is moved to the bottom of the discharge port of the storage hopper 2. Under the action of magnetic force, the chip collecting bucket 31 fits tightly with the discharge port of the storage hopper 2, effectively preventing the leakage of residue during the collection process. The residue discharged from the discharge port of the storage hopper 2 falls directly into the chip collecting bucket 31 under the action of gravity, thereby realizing efficient and leakage-free collection of the residue. After cleaning is completed, the electric slide bar 12 drives the connecting frame 13 to reset the chip collecting bucket 31.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
