A retractable spraying rod for a spraying device

Abstract

The invention belongs to the field of plant protection, and particularly relates to a crinkle type pesticide spraying rod used for a pesticide spraying device. The crinkle type pesticide spraying rod comprises a base, a controller, a transmission module, a winding drum and a pesticide spraying rod body, the base is connected with an external device in a bolted mode or in a welding mode, the controller is located on the base and connected with the base through bolts, the transmission module is located above the base, the winding drum is located above the base and matched with the transmission module in work, and the pesticide spraying rod body is wound along the winding drum and enters and exits from the lower portion of the winding drum. The mode that the controller, the transmission module, the winding drum and the pesticide spraying rod body are cooperated is adopted, automatic spreading and winding of the pesticide spraying rod body are achieved, and the portability of the pesticide spraying rod is greatly improved; the mode that a plurality of rod body units are spliced into the pesticide spraying rod body is adopted, the pesticide spraying rod body can be extended or shortened by adding or disassembling the rod body units so that the crinkle type pesticide spraying rod can be applicable to occasions of various widths, and the range of application of the crinkle type pesticide spraying rod is greatly enlarged.

Description

technical field [0001] The invention belongs to the field of plant protection, in particular to a retractable spraying rod for a spraying device. Background technique [0002] Plant protection is an important part of agricultural and forestry production, and one of the important measures to ensure the high yield of agricultural and forestry. In order to carry out plant protection economically and effectively, various control methods and positive effects should be brought into play, and the policy of "prevention first, comprehensive control" should be implemented to eliminate diseases, insects, weeds and other harmful organisms before they are harmful, and prevent them from causing disasters. The classification method of plant protection machinery can generally be divided into: human plant protection machinery, animal power plant protection machinery, small power plant protection machinery, tractor supporting plant protection machinery, self-propelled plant protection machine...

AI Technical Summary

Problems solved by technology

[0003] Existing spraying machines for plant protection vehicles generally use a spraying rod fixedly installed on the plant protection vehicle. The spraying rod can realize the spraying effect on the field, but the spraying rod is often long and fixed, causing the The medicine rod is not convenient to carry, and it is inconvenient to install during use
