Technical Field

[0001] The utility model relates to the technical field of medicine spraying vehicles, in particular to a hand-pushed medicine spraying vehicle. Background Art

[0002] A medicine spraying machine is a kind of agricultural machinery that disperses liquids. It is a type of agricultural pesticide application machinery and belongs to the plant protection machinery in agricultural machinery. It is a portable agricultural machinery, also known as a high-stem crop spraying machine or a field bathing spraying machine. The medicine spraying machine is suitable for the prevention and control of pests and diseases in forests, nurseries, orchards, and tea gardens, the prevention and control of pests and diseases in large fields such as cotton, wheat, rice, and corn, and large areas of grasslands, the prevention and control of pests and diseases in urban and suburban garden flowers, vegetable gardens, and greenhouse plants, the sanitation disinfection of hospitals, meeting rooms, cinemas, stadiums, docks, stations, buses, and passenger trains, and the disinfection and sterilization treatment of urban sewers, heating channels, basements, air raid shelters, and various cargo warehouses.

[0003] For example, a hand-pushed medicine spraying vehicle disclosed in Chinese Patent (CN209152092U) includes a main frame, a fixing mechanism, and a supporting mechanism. Casters are connected to the bottom of the main frame. An operation panel is connected to one side surface of the top of the main frame.

One end of the winding disc is connected to a winding disc handle. A water pipe is connected to the outer surface of the winding disc. The end of the water pipe is connected to a spray gun. Through the design of the fixing mechanism, it is convenient to properly place the spray gun horizontally and solves the problem that the spray gun is not easy to place when connected to the water pipe. Through the design of the supporting mechanism, the user can lift the water pipe beside the foot upward during the medicine spraying process to avoid the water pipe hanging down beside the foot and causing obstruction. Moreover, the supporting mechanism can also reduce the fatigue of the user's arm during the medicine spraying process. At the same time, the purpose that the user can hold the spray gun with one hand to spray medicine is realized.

[0004] The above solution still has the following technical deficiencies. The above solution is not convenient to remove the winding disc. The winding disc of the above solution is fixedly installed at the top end of the main frame. When the device needs to be carried, the winding disc and the main frame need to be carried together, so more force is required to carry the winding disc and the main frame together, and it is impossible for people with less strength to carry them.
