Adjustable seed taking ring on seeder

Abstract

The invention discloses an adjustable seed taking ring on a seeder, and relates to the technical field of agricultural machineries. The adjustable seed taking ring comprises a shell, a seed passage ring matched with the shell is fixedly arranged at the inner side of the shell, and a seed outlet is formed in the bottom of the seed passage ring. According to the adjustable seed taking ring, by meansof the principle that a first magnet and multiple sets of second magnets attract each other in the same polarity and repel each other in the opposite polarity, the multiple second magnets drive ejector pins to sequentially slide in the manner of attracting each other or repeling each other with the first magnet, so that the whole adjustable seed taking ring is small in abrasion during operation,long in service life, firm in seed protection and free of worries about vibration, rocking and influences of the outside such as slopes; the adjustable seed taking ring is arranged, and the adjustableseed taking ring is rotated through an adjusting gear, so that three groups of seed storage pits with different sizes on the inner side of the adjustable seed taking ring correspond to the tail endsof the ejector pins, the ejector pins can be used for ejecting and fixing seeds with different sizes, and disassembly and assembly are not needed; and disc replacement is convenient and easy, and theadjustable seed taking ring is suitable for various models.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adjustable seed circle on a seeder. Background technique [0002] The seeder refers to the planting machinery that uses crops and seeds as the sowing objects. The seeder has the characteristics of uniform seeding, consistent depth, stable row spacing, good soil covering, seed saving, and high work efficiency. The seed ring technology on the seeder is particularly critical. [0003] For the size of the seeds in the current seeder, the small grains form double plants and the large grains form holes when sowing, resulting in the phenomenon of lack of seedlings, broken ridges and multiple seedlings, and the failure to reach the precision results in reduced production. Contents of the invention [0004] The purpose of the present invention is: in order to solve the size of the seed in the prior art, when sowing, small grains form double plants and large grains form...
