A precision air suction seed device and operation method with variable line spacing

Abstract

The invention discloses a precision air suction seed device and an operation method with variable row spacing, and belongs to the technical field of sowing agricultural machinery. A precision air suction device with variable line spacing, including a housing, a distribution pipe and a suction assembly. The housing is provided with a row spacing adjustment mechanism. It is connected with the secondary distribution pipeline, the primary distribution pipeline is connected in the shell, the primary distribution pipeline is composed of straight pipe section I and two sets of tapered pipe sections I, two sets of tapered pipe sections I are connected at both ends of straight pipe section I, and straight pipe section I The air source interface and the secondary distribution pipeline are composed of a straight pipe section II in the middle and two sets of tapered pipe sections II. In cooperation, the suction components are evenly distributed at the bottom of the secondary distribution pipeline; the present invention utilizes the variable number and diameter of the secondary distribution pipeline to adjust the air pressure level and versatility.

Description

A precision gas suction seed device and operation method with variable row spacing technical field The present invention relates to sowing agricultural machinery technical field, relate in particular to a kind of precision gas suction seed device of variable row spacing and working methods. Background technique In recent years, along with the development demands of cultivation operations such as rice seedling raising, vegetable seedling raising and precision sowing of wheat, air-suction type Sowing technology is used more and more widely in the sowing operation of precision agriculture, and its core technology is concentrated in air-suction precision seed picking. on the device. At present, there are three types of air-suction precision seed pickers: air-suction drum type, air-suction whole disc type and suction-needle type. The seed picker has the advantages of no seed damage, high hole alignment accuracy, high single-grain rate, and good seed suction and discharge...
