Description
Technical Field
The invention relates to the field of seeding machines, in particular to a pneumatic flexible bowl seeder.
Background
At present, two types of precision seeding modes are commonly adopted, namely an air suction type seeder and a hole type seeder, wherein seed suction holes or seed filling holes are distributed on the cylindrical surface of a cylinder to realize three processes of precision seed taking, seed holding and seed placing so as to realize seed sowing to a designated position. The air suction type seeder adsorbs seeds on the seed suction holes by forming the pressure difference between the inside and the outside of the seed suction holes through the vacuum of the closed space on the cylindrical surface, which is provided with the back parts of the seed suction holes, and the air suction type seeder adsorbs seeds in the seed charging area, operates under the pressure difference, keeps the seeds sucked through the seed holding area, releases the negative pressure when reaching the seed releasing area, releases the seeds releasing, and can realize single seed sowing. The seed sucking hole is used for determining the size of the seed sucking hole according to the type and the size of the sucked seeds. The hole type seeder is characterized in that holes corresponding to seeds are distributed on the cylindrical surface, and the size of the holes can be set according to the size, shape and sowing quantity of the seeds. In the sowing process, in the seed filling area, seeds are filled into the holes, excessive seeds are removed, a protection element covers the holes through the seed holding area so as to prevent the seeds from falling off from the holes, in the seed placing area, the holes are separated from the protection element to cover the holes, the seeds are separated from the holes under the action of gravity, and the seeds are sowed to corresponding positions, so that the precision sowing is realized.
In reality, both precision sowers have some problems, which can affect practical application. The suction type seeder not only adsorbs seeds, but also can adsorb other substances, so that impurities (such as seed coats, micro-stems, root buds of germinated seeds and the like) in the seeds are adsorbed and blocked in the suction holes, holes are formed due to the suction leakage phenomenon during seeding, particularly, a large number of suction holes are blocked after long-time seeding, and the phenomenon that the seeds cannot be sowed is always one of the reasons for influencing the wide application of the suction type seeder, and the hole type seeder has relative movement of a seed protection element covered on the hole and a hole roller, so that the seed protection element damages the seeds in the hole, and the seeds are damaged, broken and clamped, thereby influencing the seeding quality.
