Dusting device and flying dusting device

Abstract

The invention discloses a dusting device and a flying dusting device. The dusting device comprises a material cylinder, a material feeding mechanism and a control unit. The material cylinder comprises a primary material tank and a secondary material tank which communicate with each other. The material feeding mechanism comprises at least one screw shaft which is used for conveying the material in the primary material tank to the secondary material tank, and one motor which is coupled with the screw shaft. The control unit controls the material feeding speed of the screw shaft through the motor. At least one material discharge hole is formed in the secondary material tank. A fan is installed in the secondary material tank for blowing the material in the secondary material tank out of the material discharge hole. The dusting device has the advantages that the control unit is used for controlling the rotation speed of the rotation shaft, thus being capable of controlling the material feeding speed of the screw shaft, and attaining the predicted requirement, and the motor can drive two or more screw shafts to feed the material simultaneously, thus enhancing the dusting uniformity to attain the goal of uniform dusting.

Description

technical field [0001] The invention relates to the field of powder spreading machines, in particular to a powder spreading device and a flying powder spreading device. Background technique [0002] In agriculture, spraying fixed powdered pesticides, solid powdered feed for fish farms, or powdered solids such as pollen are often carried out. Currently, manual powder spraying devices are used, which not only has a large workload, but also has low efficiency. The use of large aircraft for dusting operations is only suitable for large fields, not small fields. When using a small unmanned remote-controlled aircraft for dusting operations, it can solve the problems of low efficiency in the manual on-site dusting process and the current problem that large-scale aircraft dusting operations are not suitable for small farmlands. However, the UAV dusting device in the prior art The uniformity of spraying is low, which affects the spraying effect of pesticides. Contents of the inven...

[0002] In agriculture, spraying fixed powdered pesticides, solid powdered feed for fish farms, or powdered solids such as pollen are often carried out. Currently, manual powder spraying devices are used, which not only has a large workload, but also has low efficiency.

Dusting operations with large aircraft are only suitable for large fields, not small fields

When using a small unmanned remote-controlled aircraft for dusting operations, it can solve the problems of low efficiency in the manual on-site dusting process and the current problem that large-scale aircraft dusting operations are not suitable for small farmlands. However, the UAV dusting device in the prior art The uniformity of spraying is low, which affects the spraying effect of pesticides
