Seed packing plant

Technical Field

The invention belongs to the field of packaging of agricultural or horticultural products, and particularly relates to a seed packaging device.

Background

The propagules characteristic of seeds (seeds), gymnosperms and angiosperms, which are formed by the ovule through pollination and fertilization, play an important role in continuing species. The seeds are closely related to human life, besides grains, oil and cotton which are necessary for daily life, medicinal (such as almond), seasoning (such as pepper) and beverage (such as coffee and cocoa) are all from the seeds, and plants, big trees and flowers and plants are also bred from the seeds. However, different plants have different sowing seasons, so that the seeds are usually packaged for storage after harvesting.

The conventional seed packaging device generally comprises a conveying belt and a storage box, wherein a discharge pipe is arranged on the storage box. During the use, place the packing box on the conveyer belt to place the seed in the storage case, through the switch of opening the discharging pipe, make the seed fall into in the packing box, fill the seed back in the packing box, close the discharging pipe, and make the conveyer belt drive the packing box and remove, thereby realize the sub-box packing to the seed. This technical scheme can be the same through the time that the discharging pipe was opened each time when packing the seed to the volume of the seed that the control got into the packing box is the same, realizes quantitative packing.

However, the above technical solutions still have the following technical problems: since some impurities or unsaturated grains are often mixed in the seeds, the impurities and the unsaturated grains are packed together when the seeds are packed, so that the germination rate is low when the seeds are sown.

the specific implementation process is as follows: the seed that will wrap up the medicine drops into in mixing box 1, the starter motor, the motor drives (mixing) shaft 2 and rotates, it makes terminal surface ring gear 31 rotate to rotate through branch 3 rotation, because terminal surface ring gear 31 and driven gear 41 mesh, make driven gear 41 drive pivot 4 and rotate, thereby realize the rotation of puddler 42, puddler 42 pivoted in-process upwards turns over the seed, make the seed collide each other, and make the seed bump with puddler 42, hit unnecessary medicine on the seed. Simultaneously start air inlet machine 6, let in ascending gas through air inlet machine 6 in to the blending barrel for the seed is kicked up, and impurity and the not full granule of mixing in the seed can be located the upper strata because weight is less.

When the stirring shaft 2 rotates, the piston rod 52 drives the piston 51 to move up and down due to the cylindrical cam structure formed by the chute 2131 and the guide block, when the piston 51 moves down, the piston 51 extrudes gas at the lower part of the piston barrel 5, and the gas enters the gas inlet section 211 through the gas inlet pipe and then flows down.

At this time, the piston 51 moves downwards to suck air into the upper part of the piston barrel 5, so that impurities and unsaturated particles in the air outlet section 213 are sucked into the upper part of the piston barrel 5 for collection.

After removing impurity and the not full granule screening in the seed through the above-mentioned step of repetition many times, start the conveying motor, the conveying motor drives sector gear 8 and rotates, when making sector gear 8 move to the below, sector gear 8 and conveying gear 72 meshing, thereby realize the rotation of drive roll, make conveyer belt 7 remove left, drive packing box 71 and move left, when sector gear 8 rotates to and breaks away from the meshing with conveying gear 72, conveyer belt 7 stops the conveying, packing box 71 just in time is located the discharge end below of discharging pipe 12, sector gear 8 meshes with rotating gear 13 simultaneously.

The continuous rotation of the sector gear 8 drives the rotating gear 13 to rotate, so that the rotating gear 13 drives the discharge valve to rotate, the discharge pipe 12 is opened, and the torsion spring starts to store energy. After the discharge pipe 12 is opened, the seeds in the mixing box 1 enter the packing box 71 through the discharge pipe 12. When the sector gear 8 is separated from the rotated wheel along with the rotation of the sector gear 8, the rotating gear 13 is reset under the action of the torsion spring, the discharge valve is closed, the sector gear 8 is meshed with the transmission gear 72 again, the transmission belt 7 is transmitted leftwards, the packing box 71 filled with seeds is transmitted leftwards, the packing box is convenient to take down, and the next empty packing box 71 is transmitted to the lower part of the discharge pipe 12.

It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, which should not be construed as affecting the effectiveness of the application and the utility of the patent.
