DETAILED DESCRIPTION OF THE INVENTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The following will be combined with Figures 1-7 to describe the present invention in detail.

[0032] A grain packaging device for grain kernels includes: a machine body 1, a material receiving mechanism, a sorting mechanism, and a packaging mechanism. The machine body 1 is a mobile vehicle device. The material receiving mechanism is arranged at the front end of the machine body 1, the sorting mechanism is arranged in the middle of the machine body 1, and the packaging mechanism is arranged at the tail end of the machine body 1;

[0033] The packaging mechanism includes a rotary assembly, multiple pairs of adsorption assemblies, and a feeding assembly. The adsorption assembly includes a clamping block 2, a first servo motor 3, a support frame 4, two telescopic cylinders 5, two suction cups 6, an air pump device 7, and two hoses 8. The clamping block 2 is fixedly installed on the rotary assembly. The first servo motor 3 is horizontally and fixedly installed in the clamping block 2. The support frame 4 is fixedly installed at the output end of the first servo motor 3. The two telescopic cylinders 5 are symmetrically and fixedly installed on both sides of the support frame 4. The two suction cups 6 are respectively fixedly installed at the output ends of the two telescopic cylinders 5. The air pump device 7 is fixedly installed in the middle of the support frame 4. The two ends of the hose 8 are respectively fixedly connected and communicated with the suction cup 6 and the port of the air pump device 7;

[0034] A plurality of discharge pipes 10 are fixedly installed at the rear end of the machine body 1 through a plurality of connecting frames 9. Solenoid valve devices 11 are fixedly installed at the bottom output ends of the plurality of discharge pipes 10. The upper ends of the plurality of discharge pipes 10 are connected and communicated with the output end of the sorting mechanism. The opening time of the solenoid valve device 11 determines the filling amount, thereby realizing quantitative filling;

[0035] Each pair of adsorption assemblies is symmetrically arranged above the rotary assembly. The feeding assembly is arranged at the input end of the rotary assembly and is used for the transportation of packaging bags.

[0036] The entire device is controlled by a control terminal. Since the control terminal is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0037] The rotary assembly includes a frame body 12, four belt pulleys 13, two rotating shafts 14, two transmission belts 15 and a power device 16. The frame body 12 is horizontally and fixedly installed at the tail end of the machine body 1. The two rotating shafts 14 are respectively rotatably installed at both ends of the frame body 12. The four belt pulleys 13 are symmetrically and fixedly sleeved on the two rotating shafts 14. The two transmission belts 15 are respectively symmetrically and rotatably embedded on two pairs of belt pulleys 13. The clamping block 2 is fixedly installed on the transmission belt 15. The power device 16 is fixedly installed on the outer side of the frame body 12, and the output end is fixedly connected to the end of the rotating shaft 14.

[0038] The feeding assembly includes a truss 17, a reel 18, two pressing wheels 19 and a second servo motor 171. The truss 17 is vertically and 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 and rotatably installed on the upper side of the truss 17, and a packaging bag is wound around the outside. The two pressing wheels 19 are symmetrically and vertically rotatably installed at the end of the truss 17 close to the frame body 12. The beginning of the packaging bag passes through the middle of the two pressing wheels 19. The second servo motor 171 is fixedly installed at the top of the truss 17, and the output end is connected to the ends of the two pressing wheels 19 through a gear set for torque transmission.

[0039] A first heat-sealing device 20 is vertically and fixedly installed at the outer end of the truss 17. A second heat-sealing device 21 is horizontally and fixedly installed at the output end of the frame body 12 through two brackets 211. A carriage 22 is vertically and fixedly installed at the output end of the truss 17. A sliding device 23 is vertically and slidably sleeved on the carriage 22. A cutting knife 24 is horizontally fixedly installed at the side end of the sliding device 23. The cutting knife 24 is sharpened on both the upper and lower sides. The cutting knife 24 can cut open the packaging bag when moving up and down. The bottom of the packaging bag is sealed by the first heat-sealing device 20, and the top is sealed by the second heat-sealing device 21.

[0040] The two pressing wheels 19 cooperate with the suction cups 6 to tighten the packaging bag, facilitating the cutting by the cutting knife 24. The power device 16 moves intermittently, coordinating with the cutting by the cutting knife 24 and the filling. The solenoid valve device 11 opens and closes intermittently to control the cut-off and conduction of the filling.

[0041] When packaging, the power device 16 operates, causing the belt pulley 13 to drive the transmission belt 15 to rotate, thereby causing multiple adsorption assemblies to rotate. When passing through the feeding assembly, the support frame 4 is in a vertical state. When passing through the beginning of the packaging bag, the two pairs of telescopic cylinders 5 extend simultaneously, causing the four suction cups 6 to contact the packaging bag simultaneously. The air pump device 7 operates, adsorbing 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 heat-sealing device 20 passes through the position of the cutting knife 24, the power device 16 stops rotating, and the sliding device 23 moves, causing the cutting knife 24 to separate the packaging bag. Then, the second servo motor 171 starts, causing the two pressing wheels 19 to convey the packaging bag for a certain distance to prepare for the next adsorption.

[0042] Then the power unit 16 operates again, causing the divided packaging bags to move. The first servo motor 3 rotates to make the packaging bag inlet face upward. At the same time, the telescopic cylinder 5 shortens, and the packaging bag opens.

[0043] After the packaging bag opens, with the operation of the rotating component, the packaging bag passes through the bottom sides of multiple discharge pipes 10 in sequence. The solenoid valve device 11 is opened, and the grains fall into the packaging bag. After sequential filling, grains of different particle sizes enter the packaging bag in sequence, realizing quantitative and uniform packaging and ensuring the packaging quality.

[0044] After sequential filling is completed, the telescopic cylinder 5 elongates to close the packaging bag containing grains. When passing through the second heat-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 shortens, and the packaged grain bag drops, completing the entire packaging process. Then the first servo motor 3 operates to rotate the support 4 by ninety degrees to prepare for the next packaging.

[0045] The material receiving 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 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. The output pipe 28 is vertically fixedly installed at the output end of the screening device 27, and the pipe orifice faces the sorting mechanism.

[0046] Both the screening device 27 and the negative pressure suction device 26 are prior arts and will not be elaborated here. The output end of the suction nozzle 25 is fixedly connected and communicated with the input end of the negative pressure suction device 26.

[0047] Just integrate the grains that need to be packaged and dried into a vertical column. The machine body 1 moves to make the suction nozzle 25 contact the grains. Under the operation of the negative pressure suction device 26, the grains enter through the suction nozzle 25 and are conveyed into the screening device 27 to remove the sand and stones mixed in the grains during the process. Then the processed grains are sent out through the output pipe 28 and enter the sorting mechanism.

[0048] The sorting mechanism includes a pneumatic device 30, a material box 31, and a dust removal component. The material box 31 is vertically fixedly installed on the upper side of the machine body 1 through two vertical frames 32. A plurality of bins 33 are vertically opened in the material box 31. The plurality of bins 33 are horizontally and longitudinally distributed. The pipe orifice of the output pipe 28 faces the inlet of the material box 31. The pneumatic device 30 is fixedly installed outside the material box 31 through two connecting rods 34, and the air outlet faces the inlet of the material box 31 and is located at the bottom side of the pipe orifice of the output pipe 28.

[0049] The pneumatic device 30 operates to generate air flow. After the grains are discharged through the output pipe 28, under the impact of the air flow, grains of different sizes fall into different bins 33 respectively, thereby realizing the classification of grains of different sizes.

[0050] The dust removal assembly includes a box body 35, multiple sieve 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 respectively rotatably installed on both sides inside the box body 35. The two ends of the connecting plate 38 are fixedly connected to the mutually adjacent end faces of the two ring bodies 37. 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 tail end of the box body 35. The tail ends of multiple sieve tubes 36 are respectively rotatably connected and communicated with the upper ends of multiple discharge pipes 10. The front ends of multiple sieve tubes 36 are rotatably sleeved on the rear side of the box body 35 and are respectively connected and communicated with multiple bins 33. The driving component is arranged on the bottom side of the box body 35. A transmission component is connected between multiple sieve tubes 36 and the ring body 37 at the rear side.

[0051] 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 inside the ring body 37 at the front side. The motor 40 is fixedly installed inside the box body 35. The first gear 41 is fixedly sleeved on the output shaft of the motor 40 and is meshed with the first gear ring 42.

[0052] The transmission component includes multiple sprockets 43, a transmission chain 44, a second gear 45 and a second gear ring 46. Multiple sprockets 43 are respectively fixedly sleeved on the tail ends of multiple sieve tubes 36. Multiple sprockets 43 are linked by a transmission chain 44. The second gear ring 46 is fixedly sleeved inside the ring body 37 at the rear side. The second gear 45 is fixedly sleeved on the tail end of the outermost sieve tube 36 and is meshed with the second gear ring 46. A spiral guide rod 47 is rotatably installed at the bottom side of the bin 33. A clamping frame 48 is fixedly installed at the front end of the sieve tube 36. A ratchet 49 is fixedly installed inside the clamping frame 48. The tail end of the spiral guide rod 47 is fixedly sleeved inside the inner ring of the ratchet 49. When the sieve tube 36 rotates, the ratchet 49 is driven to operate through the clamping frame 48. When the rotation direction of the sieve tube 36 makes the spiral guide rod 47 flow backward, the ratchet 49 meshes and drives the spiral guide rod 47 to rotate, and the screened grains are introduced from the bin 33 into the sieve tube 36. When the rotation direction of the sieve tube 36 makes the spiral guide rod 47 flow forward, the ratchet 49 slips. At this time, the spiral guide rod 47 does not rotate, the grains freely fall into the sieve tube 36, and the spiral guide rod 47 does not push forward.

[0053] After the grains fall into the bin 33, they will move backward into the corresponding sieve tube 36. The motor 40 rotates reciprocally, drives the ring body 37 and the connecting plate 38 to rotate reciprocally within the upper semi-circle of 180 degrees through the first gear 41 and the first gear ring 42, drives the fan device 39 to operate, and performs dust removal on the grains flowing through the sieve tube 36 to ensure that the grains are in a clean state.

[0054] During the transmission process of the ring body 37, the second gear ring 46 is driven to rotate. The second gear ring 46 drives the sieve tube 36 to rotate through the second gear 45. With the cooperation of multiple sprockets 43 and the transmission chain 44, multiple sieve tubes 36 rotate simultaneously. Combining with the rotation of the fan device 39, the grains can be cleaned more thoroughly, thereby further ensuring the quality of the packaged grains.

[0055] Both sides of the bottom of the box body 35 are inclined outlets, and the dust cleaned down is discharged through the outlets on both sides.

[0056] During the entire packaging process, there is no need for excessive human intervention. The picking, sorting, and packaging of grain kernels are completed in sequence, greatly reducing the labor intensity and improving the efficiency.

[0057] As described above, it is only the specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
