[0002] Seeds are reproductive bodies unique to gymnosperms and angiosperms. They are formed by ovules through pollination and fertilization. Seeds are generally composed of three parts: seed coat, embryo and endosperm. Some mature seeds of plants only have seed coat and embryo. After harvesting, the seeds of some agricultural products need to be bagged and stored for easy sale or warehousing. Patent search found that the publication number is: CN217022969U, which discloses a seed quantitative filling mechanism. By starting the conveying motor to drive the conveying rod in the conveying pipe, it is convenient to convey the seeds in the discharge hopper to the discharge trough, and flow into the quantitative groove inside the connecting plate through the hose. By starting the hydraulic cylinder, the connecting plate is connected to the packaging can through the extended hydraulic rod, and the seeds in the quantitative groove flow into the packaging can through the discharge port, which greatly reduces the use of manpower and improves production efficiency.

[0003] Publication No.: CN217022969U, discloses a seed quantitative filling mechanism. When filling peanut seeds, the distance between the filling head and the bottle mouth cannot be adjusted. When filling a filling bottle with a lower height, there is a certain distance between the filling head and the bottle mouth. There is a risk that the peanut seeds will not fall into the filling bottle, affecting the filling accuracy of the peanut seeds. At the same time, the gaps between the peanut seeds are large, resulting in the height of the peanut seeds reaching the bottle mouth after filling, which will have a certain impact on the sealing of the filling bottle. In order to solve the above problems, a seed quantitative filling mechanism is proposed in the present application. Utility Model Content
