Fan assembly of air-aspiration type planting machine

Abstract

The invention discloses a fan assembly of an air-aspiration type planting machine. A fan wheel (26) in a fan (1) is connected with a wheel (10) in a unidirectional automatic clutch device through a ribbed belt (2) in a transmission manner; one end of a negative pressure suction hole (25) in the fan (1) is connected with a negative pressure stabilizer (11), and the other end of the negative pressure suction hole (25) is connected with a planter of the planting machine. By the adoption of the ribbed belt (2), the fan assembly of the air-aspiration type planting machine can change the speed in position at a time; furthermore, the ribbed belt (2) is difficult to slip, so that the transmission efficiency is improved; due to the additional arrangement of the unidirectional automatic clutch device, when a tractor is deaccelerated rapidly during working, the fan can still continuously run under the action of the inert, so that the slip abrasion of the belt is alleviated, and the stability of instant air pressure of the fan is improved; the negative pressure stabilizer (11) is designed in order to realize the stable and high-efficiency planting, so that the fan can be greatly improved during running.

Description

technical field [0001] The invention relates to an air-suction seeder fan assembly, which belongs to the technical field of agricultural machinery. Background technique [0002] The known seeder has not solved the phenomenon of missing seeding caused by the tractor idling and turning. One is to increase the speed through the gearbox; Make the wind pressure unstable during work, etc. There is also a kind of electronic fan technology that has appeared in the past two years. Due to the harsh working environment, this electronic fan technology often causes the filter screen of the fan to be blocked and the wind pressure is reduced. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the deficiencies existing in the original fan of the seeder and provide an air-suction fan assembly for the seeder. [0004] The technical solution of the present invention is: the fan wheel (26) in the fan (1) is connected with the wheel (10) i...

Problems solved by technology

[0002] The known seeder has not solved the phenomenon of missing seeding caused by the tractor idling and turning. One is to increase the speed through the gearbox; Unstable wind pressure during work, etc.

Another thing is an electronic fan technology that has appeared in the past two years. Due to the harsh working environment, this electronic fan technology often causes the filter screen of the fan to be clogged and the wind pressure is reduced.
