[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5This utility model provides an embodiment: a bagging device for seed production, including a workbench 1, a seed hopper 2 above the workbench 1, the seed hopper 2 including a placement cavity 20 for holding seeds, a conveying box 21 at the bottom of the seed hopper 2 connected to the placement cavity 20, a feeding part inside the conveying box 21 for conveying seeds from the placement cavity 20 and the conveying box 21 to the outside of the conveying box 21, and a conveying cylinder 22 at the front of the conveying box 21. A discharge port 222 is provided on one side facing the workbench 1. A bagging section is provided on the top of the workbench 1 below the discharge port 222. The bagging section includes suction cups 311 on the left and right sides of the conveyor cylinder 22. The suction cups 311 are located below the conveyor cylinder 22. The suction cups 311 can adsorb the surface of the packaging bag. By adsorbing the packaging bag with the suction cups 311 of the bagging section, the opening of the packaging bag is opened, avoiding the trouble of manually opening the bag and increasing production efficiency. The conveyor box 21 of the feeding section concentrates the seeds in the box, making it easy to transport them to the outside for bagging.

[0023] Please see Figure 1 - Figure 4In this embodiment, support plates 11 are provided on the left and right sides of the top of the workbench 1. The support plates 11 are connected to the outer wall of the seed hopper 2. The two support plates 11 are located on the left and right sides of the conveying box 21, respectively. An auger 211 is provided inside the conveying box 21. One axial end of the auger 211 is connected to the interior of the conveying box 21, and the other axial end of the auger 211 can extend through the conveying box 21 to the interior of the conveying cylinder 22. The conveying cylinder 22 and the auger 211 are coaxially arranged. The auger 211 can rotate inside the conveying box 21 and the conveying cylinder 22. The support plates 11 support the seed hopper 2, so that the auger 211 can convey the seeds in the conveying box 21 to the conveying cylinder 22, which is convenient for discharge from the outlet 222. The opening of the conveying cylinder 22 faces the rear. A flange 221 is provided at the outer diameter of the rear side of the conveying cylinder 22. The flange 221 can be connected to the outer wall of the conveying box 21. The conveying box 21 is away from the conveying cylinder. A motor 24 is provided on the outer wall of one side of the conveyor cylinder 22. The output shaft of the motor 24 can be connected to the auger 211. The conveyor cylinder 22 is supported by the flange 221 of the conveyor cylinder 22 to reduce the lateral load on the auger 211. The motor 24 can drive the auger 211 to rotate. A bagging frame 3 is provided on the top of the workbench 1 below the discharge port 222. The bagging frame 3 includes a second plate 302. The left and right sides of the front side of the second plate 302 are provided with a first plate 301. A movable plate 31 is provided on the side of the first plate 301 facing the conveyor cylinder 22. A suction rod 312 is engaged on the movable plate 31. One end of the suction rod 312 is located on the left side of the movable plate 31, and the other end of the movable plate 31 is located on the right side of the movable plate 31. A suction cup 311 is provided on the side of the suction rod 312 facing the axis of the conveyor cylinder 22. The movable plate 31 supports the suction cup 311 and the suction rod 312, so that the movable plate 31 can move with the suction cup 311 and the suction rod 312 to realize the bag opening action.

[0024] Please see Figure 2 - Figure 5 In this embodiment, a cylinder 33 is installed on the side of plate 301 away from the conveyor cylinder 22. The output rod of the cylinder 33 can pass through plate 301 and connect to the side of the moving plate 31 away from the conveyor cylinder 22. The cylinder 33 automatically pushes the moving plate 31 to move, so that the suction cup 311 adsorbs the two sides of the opening of the packaging bag to open the bag. A guide rod 34 is provided on the side of the moving plate 31 away from the axis of the conveyor cylinder 22. Plate 301 is provided with guide holes corresponding to the guide rod 34. The guide rod 34 increases the... The stability of the moving plate 31 is improved, the radial load on the cylinder 33 is reduced, and the service life of the cylinder 33 is extended. A pad is provided on the top of the workbench 1 corresponding to the inner side of the bagging frame 3. Two guide plates 42 are provided on the front side of the bagging frame 3. The two rollers 41 are rotatably connected to each other. An inclined plate 421 is provided on the rear side of the guide plate 42. The inclined plate 421 is offset to the side away from the axis of the conveyor cylinder 22. The height difference with the roller 41 is compensated by the pad, which makes it easier to pick up the packaging bag full of seeds, saving time and effort.

[0025] During operation, seeds fall from the previous device into the placement chamber 20 of the seed hopper 2. The seeds in the placement chamber 20 slide into the conveyor box 21, filling the conveyor box 21. The motor 24 drives the auger 211 to rotate, and the auger 211 presses the seeds in the conveyor box 21 into the conveyor cylinder 22. Subsequently, the seeds in the conveyor cylinder 22 fall from the discharge port 222 of the conveyor cylinder 22 under the rotation of the auger 211. Here, packaging bags are pre-placed at the bagging section. The packaging bags here must be plastic bags or the woven bags used for packaging rice in supermarkets, not burlap bags. The bottom of the packaging bag is in contact with the pad, and one side of the opening of the packaging bag is in contact with the suction cup 311 on either side. The vacuum generating device creates a vacuum by drawing a vacuum between the suction rod 312 and the suction cup 311, so that the opening on one side of the packaging bag is in contact with the bagging section. The suction cups 311 on one side of the bag are attached to each other, and then the two cylinders 33 extend simultaneously, causing the suction cups 311 on the other side to adhere to the other side of the packaging bag. Then the two cylinders 33 retract simultaneously, thus opening the packaging bag. Here, the auger 211 drives the seeds to fall from the discharge port 222 of the conveyor cylinder 22 into the opened packaging bag. When filling the packaging bag, the bottom of the packaging bag will be filled first. After about one-quarter of the bag is filled, the suction force of the vacuum generator of the suction cups 311 weakens. When it is three-quarters full, it is considered full. The amount of seeds in the packaging bag is detected by the pressure sensing device at the bottom of the pad. The side of the suction rod 312 away from the suction cups 311 needs to be connected to the vacuum generator through a pipeline. The air circuit, electrical control and program here are all existing technologies, and their working principle will not be described in detail here.

[0026] Through the above steps, the suction cup 311 of the bagging section adsorbs the packaging bag, opening the bag and avoiding the trouble of manual bag opening, thus increasing production efficiency. The conveyor box 21 of the feeding section concentrates the seeds in the box, making it easy to transport them to the outside for bagging. This solves the problem in the prior art that the packaging bag needs to be opened manually during the bagging process, resulting in low bagging efficiency. At the same time, when the seeds need to pass through the bagging barrel once, they are easy to fall onto the surface of the device, causing great waste.
