Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a pesticide spraying vehicle with a retractable spraying rod. Background Art

[0002] In modern agricultural production, especially after large-scale planting, the mechanization of agricultural production has increased agricultural production output while reducing manpower, and agricultural machinery has replaced manual planting, which has played an important role in the development of agricultural planting. There are many types of agricultural machinery, among which sprayers are frequently used machines. The spray boom is a tool for the sprayer to disperse the liquid and is an indispensable part of the spraying operation of the sprayer.

[0003] With the continuous development of agricultural mechanization, large-scale spraying equipment is often used in agricultural work to carry out large-scale spraying operations on crops. This is only for small-scale farms or specific environments, such as small-scale, multi-regional and dense planting environments such as Shanghai green and kale. In this type of planting environment, if a sprayer is used to spray, the sprayer can only move on the road beside the field and cannot operate in the field. Therefore, if the length of the spray rod is fixed, it is impossible to spray Shanghai green and other crops on the road. The operator needs to get off the vehicle and use a long tube to operate. In addition, the pesticide storage barrels installed in most sprayers are fixed and cannot be disassembled separately. It is inconvenient to clean the pesticide storage barrels after spraying.

[0021] Specifically, two supporting brackets 8 are arranged on the top of the liquid storage barrel base 7 on one side of the pesticide liquid storage barrel 6, and a reinforcement frame 9 is hingedly installed on the top of the supporting bracket 8. A slot 10 is arranged on the bottom of the reinforcement frame 9. When installing the pesticide liquid storage barrel 6, the reinforcement frame 9 is flipped and fixed above the pesticide liquid storage barrel 6 and clamped to prevent the pesticide liquid storage barrel 6 from shaking or falling when the sprayer is moving.

[0022] Furthermore, two fixed brackets 14 are provided on the top of the liquid storage barrel base 7 on one side of the two supporting brackets 8, and two buckles 13 are provided at the top edges of the two fixed brackets 14. The buckles 13 are detachably inserted into the slots 10, and the reinforcement frame 9 is detachably installed on the top of the fixed brackets 14 through the slots 10 and the buckles 13, so as to ensure the stability of the pesticide liquid storage barrel 6 and facilitate the disassembly of the pesticide liquid storage barrel 6.

[0023] Furthermore, four rollers 2 are provided at the bottom end of the frame 1, so that the pesticide sprayer can travel on the road beside the planting field.
