Quick adjustable air suction type seed taking device

Abstract

The invention discloses a rapid adjustable air suction type seed taking device which comprises a mounting table, an air chamber is arranged on the mounting table, the open end of the front end of an air cavity of the air chamber is in a cylindrical shape with a section of notch, the open end of the front end of the air cavity is closed through a seed suction disc, a transmission shaft is rotationally arranged in the center of the air chamber, and the seed suction disc is fixed to the transmission shaft. A plurality of groups of different seed suction holes are formed in the seed suction disc along the radial direction, a plurality of groups of closing assemblies are arranged in the air cavity, the plurality of groups of closing assemblies are in one-to-one correspondence with the plurality of groups of seed suction holes of the seed suction disc, and each group of closing assemblies is adjusted to be independently close to or far away from the seed suction disc through an adjusting device, so that the corresponding groups of seed suction holes in the seed suction disc are closed or opened; an adjustable seed box and a seed receiving box are further arranged on the mounting table, a height-adjustable bottom plate is arranged at the bottom of the adjustable seed box, and the seed receiving box is used for receiving seeds falling off due to loss of negative pressure at the seed suction holes in the seed suction disc. The seed taking device has the advantages that rapid and accurate seed taking of different types of seeds is realized, and the universality of the seed taking device is enhanced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a fast adjustable air suction type seed picking device. Background technique [0002] The air-suction planter is a planter that uses negative pressure to take seeds to achieve the purpose of precision sowing. Compared with the traditional mechanical planter, it has strong advantages in performance and technical content. The seed picking device is the core component of the air-suction planter. Its performance directly affects the working quality of the seeder. Compared with the mechanical seed picking, the air-suction seed picking device can better achieve single seed picking. It can effectively reduce the problems of missed seeding and re-seeding caused by insufficient seed quality during the sowing process. At the same time, in the process of seed picking, the air-suction seed picking method causes less damage to the seeds, and also has the advantage...

AI Technical Summary

Problems solved by technology

However, due to structural limitations, the air-suction seed picking device still has problems such as unstable seed picking, poor adaptability to seed picking objects, and poor versatility of seed picking components.

When the equipment is sowing, it is necessary to replace the seed picking parts according to the shape and size of the sowing seeds. Due to the complicated structural design of the air suction seeding device, the replacement process of the seed picking parts is cumbersome, which in turn reduces the use efficiency of the seeding device and increases labor. Intensity, how to improve the adaptability of the seeding device of the air-suction seeder, satisfy the rapid and accurate seeding of different types of seeds, and enhance the versatility, reliability and efficiency of the seeding device, for the development and development of the air-suction seeder It is important to promote the application
