[0017] Combine the following Figure 1-7 The present invention is described in detail.

The upper ends of the plurality of discharge pipes 10 are connected to the output end of the sorting mechanism. The opening time of the solenoid valve device 11 determines the filling amount, thereby realizing quantitative filling; Each pair of adsorption components is symmetrically arranged on the upper side of the rotary component, and the feeding component is arranged at the input end of the rotary component for conveying packaging bags.

[0019] The entire device is controlled by a control terminal. Since the control terminal is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0020] The rotary assembly includes a frame 12, four pulleys 13, two rotating shafts 14, two transmission belts 15 and a power device 16. The frame 12 is horizontally fixedly installed at the rear end of the machine body 1, and the two rotating shafts 14 are respectively rotatably installed at both ends of the frame 12. The four pulleys 13 are symmetrically fixedly sleeved on the two rotating shafts 14. The two transmission belts 15 are respectively symmetrically rotatably embedded in the two pairs of pulleys 13. The block 2 is fixedly installed on the transmission belt 15. The power device 16 is fixedly installed on the outside of the frame 12, and the output end is fixedly connected to the end of the rotating shaft 14.

[0021] The feeding assembly includes a truss 17, a reel 18, two pressure wheels 19 and a second servo motor 171. The truss 17 is vertically fixedly installed on the side of the machine body 1 and is located in the middle of the two transmission belts 15. The reel 18 is vertically rotatably installed on the upper side of the truss 17, and a packaging bag is wound on the outside. The two pressure wheels 19 are symmetrically vertically rotatably installed at the end of the truss 17 close to the frame body 12, and the opening of the packaging bag passes through the middle of the two pressure wheels 19. The second servo motor 171 is fixedly installed on the top of the truss 17, and the output end is connected to the ends of the two pressure wheels 19 through a gear set for torque transmission.

[0022] A first thermoplastic sealing device 20 is vertically fixedly installed at the outer end of the truss 17, and a second thermoplastic sealing device 21 is horizontally fixedly installed at the output end of the frame body 12 through two brackets 211. A slide 22 is vertically fixedly installed at the output end of the truss 17, and a sliding device 23 is vertically slidably sleeved on the slide 22. A cutting knife 24 is horizontally fixedly installed on the side end of the sliding device 23. The cutting knife 24 has blades on the upper and lower sides, and the cutting knife 24 can cut the packaging bag by moving up and down. The bottom of the packaging bag is sealed by the first thermoplastic sealing device 20, and the top is sealed by the second thermoplastic sealing device 21.

[0023] The two pressing wheels 19 and the suction cup 6 cooperate to tighten the packaging bag to facilitate cutting by the cutter 24. The power device 16 moves intermittently to cooperate with the cutting and filling of the cutter 24. The solenoid valve device 11 opens and closes intermittently to control the cutoff and conduction of the filling.

[0024] When packaging, the power device 16 operates, so that the pulley 13 drives the transmission belt 15 to rotate, thereby causing multiple groups of adsorption components to rotate. When passing the feeding component, the support frame 4 is in a vertical state. When passing the beginning of the packaging bag, the two pairs of telescopic cylinders 5 extend at the same time, so that the four suction cups 6 are in contact with the packaging bag at the same time, and the air pump device 7 operates to adsorb the packaging bag through the hose 8. As the transmission belt 15 rotates, the packaging bag is stretched. When the part of the packaging bag sealed by the first thermoplastic sealing device 20 passes the position of the cutter 24, the power device 16 stops, and the sliding device 23 moves, so that the cutter 24 separates the packaging bag, and then the second servo motor 171 starts, so that the two pressure wheels 19 convey one end of the packaging bag to prepare for the next adsorption.

[0025] Then the power device 16 is operated again to move the divided packaging bag, and the first servo motor 3 rotates to make the inlet of the packaging bag face upward, while the telescopic cylinder 5 is shortened and the packaging bag is opened.

[0026] After the packaging bag is opened, with the operation of the rotating part, the packaging bag passes through the bottom side of multiple discharge pipes 10 in sequence, the solenoid valve device 11 opens, and the grain falls into the packaging bag. After being filled in sequence, grains of different particle sizes enter the packaging bag in sequence, achieving quantitative and uniform packaging and ensuring the quality of packaging.

[0027] After the filling is completed in sequence, the telescopic cylinder 5 is extended to close the packaging bag containing the grain. When passing through the second thermoplastic sealing device 21, the bag mouth is sealed. After the sealing is completed, the air pump device 7 stops rotating to release the adsorption force. At the same time, the telescopic cylinder 5 is shortened, and the sealed grain bag falls down, completing the entire packaging process. Then the first servo motor 3 is operated to rotate the support frame 4 ninety degrees to prepare for the next packaging.

[0028] The material collecting mechanism includes a suction nozzle 25, a negative pressure suction device 26, a screening device 27 and an output pipe 28. The suction nozzle 25 is fixedly installed at the front end of the machine body 1 through a fork frame 29, the negative pressure suction device 26 is fixedly installed inside the machine body 1, the screening device 27 is fixedly installed at the output end of the negative pressure suction device 26, and the output pipe 28 is vertically fixedly installed at the output end of the screening device 27, and the pipe mouth faces the sorting mechanism.

[0029] The screening device 27 and the negative pressure suction device 26 are both prior arts and will not be described in detail herein. The output end of the suction nozzle 25 is fixedly connected and conducted to the input end of the negative pressure suction device 26 .

[0030] The dried grains to be packaged can be integrated into a vertical row, and the machine body 1 moves so that the suction nozzle 25 contacts the grains. Under the operation of the negative pressure suction device 26, the grains enter through the suction nozzle 25 and are transported to the screening device 27. The sand and gravel mixed into the grains during the process are cleaned out, and then the processed grains are sent out through the output pipe 28 and enter the sorting mechanism.

[0031] The sorting mechanism includes a pneumatic device 30, a material box 31 and a dust removal assembly. The material box 31 is vertically fixed on the upper side of the machine body 1 by two vertical frames 32. A plurality of material bins 33 are vertically opened in the material box 31. The plurality of material bins 33 are horizontally and longitudinally distributed. The outlet of the output pipe 28 faces the entrance of the material box 31. The pneumatic device 30 is fixedly installed on the outside of the material box 31 by two connecting rods 34, and the air outlet faces the entrance of the material box 31 and is located at the bottom side of the outlet of the output pipe 28.

[0032] The pneumatic device 30 operates to generate airflow. After the grain is discharged through the output pipe 28, grain particles of different sizes fall into different silos 33 under the impact of the airflow, thereby achieving the classification of grain particles by size.

[0033] The dust removal assembly includes a box body 35, multiple screen tubes 36, two ring bodies 37, a connecting plate 38, a fan device 39 and a driving component. The box body 35 is fixedly installed on the upper side of the machine body 1, and the upper side is inclined. The two ring bodies 37 are rotatably installed on both sides of the inside of the box body 35, and the two ends of the connecting plate 38 are respectively fixedly connected to the end faces of the two ring bodies 37 that are close to each other. The fan device 39 is fixedly installed on the bottom surface of the connecting plate 38. The upper ends of multiple discharge pipes 10 are fixedly sleeved on the rear end of the box body 35, and the rear ends of multiple screen tubes 36 are respectively rotatably connected and communicated with the upper ends of multiple discharge pipes 10. The front ends of multiple screen tubes 36 are rotatably sleeved on the rear side of the box body 35, and are respectively connected and communicated with multiple silos 33. The driving component is arranged on the bottom side of the box body 35, and the multiple screen tubes 36 are connected to the ring body 37 on the rear side through a transmission component.

[0034] The driving component includes a motor 40, a first gear 41 and a first gear ring 42. The first gear ring 42 is fixedly sleeved in the ring body 37 located on the front side. The motor 40 is fixedly installed in the box body 35. The first gear 41 is fixedly sleeved on the output shaft of the motor 40 and meshingly connected with the first gear ring 42.

[0035] The transmission components include a plurality of sprockets 43, a transmission chain 44, a second gear 45 and a second gear ring 46. The plurality of sprockets 43 are respectively fixedly sleeved on the tail ends of the plurality of screen tubes 36. The plurality of sprockets 43 are linked by the transmission chain 44. The second gear ring 46 is fixedly sleeved in the ring body 37 located at the rear side. The second gear 45 is fixedly sleeved on the tail end of the outermost screen tube 36 and meshed with the second gear ring 46. A spiral guide rod 47 is rotatably installed on the bottom side of the silo 33. A bracket 48 is fixedly installed on the front end of the screen tube 36. A second gear 45 is fixedly installed in the bracket 48. There is a ratchet 49, and the tail end of the spiral guide rod 47 is fixedly sleeved on the inner circle of the ratchet 49. When the screen tube 36 rotates, the ratchet 49 is driven to operate through the bracket 48. When the screen tube 36 turns to make the spiral guide rod 47 divert the flow backward, the ratchet 49 engages and drives the spiral guide rod 47 to rotate, and the screened grain is introduced from the silo 33 into the screen tube 36. When the screen tube 36 turns to make the spiral guide rod 47 divert the flow forward, the ratchet 49 slips. At this time, the spiral guide rod 47 does not rotate, and the grain falls freely into the screen tube 36, and the spiral guide rod 47 does not advance.

[0036] After the grain falls into the silo 33, it moves backward to the corresponding screen tube 36. The motor 40 rotates back and forth, driving the ring body 37 and the connecting plate 38 to rotate back and forth in the upper semicircle of 180 degrees through the first gear 41 and the first gear ring 42, driving the fan device 39 to operate, and performing dust removal operations on the grain flowing through the screen tube 36 to ensure that the grain is in a clean state.

[0037] During the transmission process of the ring body 37, the second gear ring 46 is driven to rotate, and the second gear ring 46 drives the screen tube 36 to rotate through the second gear 45. With the cooperation of multiple sprockets 43 and the transmission chain 44, multiple screen tubes 36 rotate at the same time, and with the rotation of the fan device 39, the grain can be more fully cleaned, thereby further ensuring the quality of the packaged grain.

[0038] Both sides of the bottom of the box body 35 are inclined outlets, and the cleaned dust is discharged through the outlets on both sides.

[0039] The entire packaging process does not require excessive human intervention, and the picking, sorting and packaging of grain grains are completed in sequence, which greatly reduces labor intensity and improves efficiency.

[0040] The above is only a specific implementation of the invention, but the protection scope of the invention is not limited to it. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the invention. Therefore, the protection scope of the invention should be based on the protection scope defined in the claims.
