Embodiment 1

[0023] Such as Figure 1-3 As shown, it is a schematic diagram of the structure of the quick-changing hole seed suction plate of the present invention, including a plate body 1 and a plurality of seed suction holes 6, the center of the plate body 1 is provided with a central through hole 4, and the periphery of the central through hole 4 is provided with mounting holes 5. Eight first counterbores are provided on the periphery of the installation hole 5 near the negative pressure chamber of the seeder, and eight second counterbores coaxial with the first counterbore are provided at the corresponding positions near the seed filling chamber. The bottoms of the first counterbore and the second counterbore communicate with each other, and the bottom surfaces are all planes parallel to the side of the disk body. The diameter of the first counterbore is larger than that of the second counterbore, and both the first counterbore and the second counterbore are circular. The depth of the...

Abstract

Belonging to the field of agricultural technologies, the invention aims to overcome disadvantages in prior art and provide a seed suction disk with rapid transforming holes able to realize convenient and rapid transformation into different sizes as well as a seeder. The seed suction disc comprises a disk body and a plurality of seed suction holes. The disk body is equipped with several detachableseed suction sheets on one side close to a seed filling chamber, and the other side of the disk body is embed with positioning disks corresponding to the detachable seed suction sheets in position and quantity. Each positioning disk is a magnetic ring provided with a through hole in the center and made of a permanent magnetic material, and the size of the through hole is smaller than sizes of thedetachable seed suction sheets. The detachable seed suction sheets are made of a magnetic induction material at least the external surfaces, and are adsorbed on the surfaces of the magnetic rings. The seed suction holes are positioned on the detachable seed suction sheets, and at least one seed suction hole is disposed within the through hole of a magnetic ring. The seed suction disk of the invention has a simple structure, and can transform the seed suction holes into different sizes and shapes rapidly and conveniently so as to adapt to sowing of different crops.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a seed sucker and a seeder for quickly changing holes. Background technique [0002] The hole disc air suction seeder is a precision seeding device commonly used in agricultural production, and it has two areas of seed suction and seed discharge. In the seed suction area, the core working part is the seed suction plate with suction holes. On the suction hole side of the suction plate, there is a low-pressure airflow below atmospheric pressure generated by an air pump or fan, while the other side is connected to the atmosphere. There is a certain pressure difference on both sides. When the seed is close to the suction hole, under the action of Pascal's theorem, the pressure difference on both sides of the hole acts on the seed to generate pressure, making it move to the low-pressure side to tightly press the surface of the suction hole, and carry it from the sucti...
