Abstract

The invention discloses an accurate quantity air-suction seed taking device capable of changing row spacing and an operation method, and belongs to the technical field of sowing agricultural machinery. The accurate quantity air-suction seed taking device capable of changing row spacing comprises a housing, a flow dividing pipeline and material sucking assemblies, wherein the housing is provided with a row spacing adjusting mechanism; the flow dividing pipeline consists of one stage flow dividing pipelines and two stage flow dividing pipelines; the one stage flow dividing pipelines and the twostage flow dividing pipelines are connected; the one stage flow dividing pipelines are connected to the inner part of the housing; each one stage flow dividing pipeline consists of a straight pipe section I and two sets of conical pipe sections I; the two sets of the conical pipe sections I are connected to two ends of the straight pipe section I; an air source interface is connected to each straight pipe section I; each two stage flow dividing pipeline consists of a middle straight pipe section II and two sets of conical pipe sections II; the two sets of conical pipe sections II are connectedto two ends of the straight pipe section II; a supporting assembly is arranged on each conical pipe section II, and cooperates with the row spacing adjusting mechanism; and the material sucking assemblies are uniformly distributed at the bottom of the two stage flow dividing pipelines. According to the accurate quantity air-suction seed taking device capable of changing row spacing disclosed by the invention, air pressure balance and the generality of are adjusted through the two stage flow dividing pipelines of which the number and the diameter are variable.

Description

Technical field [0001] The invention relates to the technical field of seeding agricultural machinery, in particular to a variable row spacing precision air suction seed device and an operation method. Background technique [0002] In recent years, with the development of rice seedling raising, vegetable seedling raising, and precision seeding of wheat and other cultivation operations, air-suction seeding technology has become more and more widely used in precision agriculture planting operations, and its core technologies are concentrated on air-suction precision seeding. On the seed extractor. At present, the commonly used air-suction type precision seed extractor includes air-suction drum type, air-suction whole disc type and needle-suction type. Among them, the needle-suction type seed extractor has the advantages of not hurting the seeds, high accuracy of hole alignment, and single grain rate. It has the advantages of high suction and discharge performance. It is widely use...
