Abstract

The invention discloses a seed metering pipe capable of preventing seed residues. The seed metering pipe comprises a rubber corrugated pipe, and further comprises a rubber pipe I, a rubber pipe II and a rubber polish pipe, the inner walls of the rubber pipe I, the rubber pipe II and the rubber polish pipe are smooth surfaces, an opening at one end of the rubber pipe I is in butt joint with an opening at one end of the rubber corrugated pipe, an opening at one end of the rubber pipe II is in butt joint with an opening at the other end of the rubber corrugated pipe, the rubber polish pipe sequentially penetrates through the rubber pipe I and the rubber corrugated pipe and is tightly attached to the inner side face of the rubber pipe I. When the rubber corrugated pipe stretches out and draws back, the rubber pipe II moves along the outer side face of the rubber polish pipe. During seeding, the external rubber corrugated pipe is stretched out and drawn back along with the fluctuation of the ground, the rubber pipe II moves along the outer side face of the rubber polish pipe, at the moment, seeds slide down along the inner wall of the rubber polish pipe all the time, the problems of blockage and the like do not exist, and the seed metering uniformity and the seed metering quality of a seeding machine are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeders, and in particular relates to a seeding pipe for preventing seeds from remaining. Background technique [0002] The seeding pipe is an important part of the seeder. The seeding pipe is connected to the seeding parts upwards, and the seeding pipe is connected to the sowing parts downward. When the seeder is working, the sowing parts will float up and down due to the uneven ground, which requires the seeding pipe to have Flexible and scalable. In the existing sowing technology, elastic and stretchable rubber bellows are generally used for the seeding pipe, but the rubber bellows has a convex and concave inner wall that will cause stuck residues on the flow of seeds, affecting the uniformity of seeding by the seeder, thereby Affect the quality of sowing, resulting in technical problems such as unequal sowing spacing. Contents of the invention [0003] Aiming at the deficiencies of th...
