Anti-blocking rubber forest sulfur powder spraying machine

Abstract

The invention provides an anti-blocking rubber forest sulfur powder spraying machine. The power spraying machine comprises a rack, a powder discharging mechanism, a centrifugal blower, a driving mechanism and a discharging mechanism, and the powder discharging mechanism comprises a connecting pipe, a contracted pipe, a feeding pipe and a powder spraying pipe. The rack is installed on a tractor, the tractor provides power, compared with manual spraying and spraying by an unmanned aerial vehicle, the machine is low in working intensity and easy to operate, the discharging mechanism conveys sulfur powder to the feeding pipe, the sulfur powder in the feeding pipe can flow into the contracted pipe, the connecting pipe and the powder spraying pipe with the pipe diameter larger than that of the contracted pipe are arranged at the upper end and the lower end of the contracted pipe respectively, upward air generated by the centrifugal blower enters the contracted pipe through the connecting pipe, so that the sulfur powder is sprayed from the powder spraying pipe, powder spraying of a rubber forest is achieved, according to the Bernoulli principle, the air speed at the contracted pipe is high, the sulfur powder in the feeding pipe can be sucked into the contracted pipe, so that the sulfur powder is prevented from blocking the feeding pipe and the connecting position of the feeding pipe and the contracted pipe, blocking is prevented, and normal powder spraying work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an anti-clogging rubber forest sulfur duster. Background technique [0002] In agricultural production activities, crops need to be sprayed with dust and pesticides for pest control. As an important resource for the production of natural rubber, rubber forests need to be regularly sprayed with pesticides during their growth. Currently, the pest control drug for rubber forests is sulfur powder. The traditional powder spraying method is to spray the sulfur powder upwards through the artificial backpack sprayer with an extended nozzle. However, the powder spraying efficiency of this method is low, and the angle of work intensity required by the staff, and due to the different sizes of the sulfur powder particles, spraying Blockages often occur in the tubes and require manual cleaning, resulting in reduced spraying efficiency.
