Four-wheeled spraying trolley with adjustable height

Abstract

The invention discloses a four-wheeled spraying trolley with adjustable height. Wheels are connected upwards with respective vertical supporting legs through wheel forks, and the upper ends of the vertical supporting legs are fixedly connected to four corner points of a frame respectively; each vertical supporting leg comprises a bottom section, a middle section and an upper section, wherein the bottom of each bottom section leg is connected to the corresponding wheel fork, the bottom section leg and the middle section leg are inserted and connected in a fastened mode through nut matching, the middle section leg and the upper section leg are inserted and connected in a fastened mode through nut matching, the bottom section leg and the upper section leg are inserted and connected in a fastened mode through nut matching, and the middle section legs are detachable legs which can be omitted or installed in the installing process of the four-wheeled spraying trolley. The four-wheeled spraying trolley has the advantages that compared with a common spraying trolley, the supporting legs of the walking wheels of the spraying trolley are arranged to be the structure with adjustable height, so that the four-wheeled spraying trolley is used for spraying pesticide to short crops as well as high crops like corn by adjusting the wheel legs to lift the frame. The four-wheeled spraying trolley with adjustable height has the advantages of being simple in structure and high in practicability.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a height-adjustable four-wheel spray vehicle. Background technique [0002] Different types of farmland crops have different plant heights during the growth period. Correspondingly, the required heights of pesticide spraying machinery are also different. The main body of the existing land-walking pesticide machinery frame is fixed at a certain height, which cannot be flexibly satisfied. The demand for pesticide application management of various crops. Take corn as an example. When it grows to a certain height, ordinary land-based medical equipment cannot travel in the corn field. At this time, the control of corn diseases and insect pests can only rely on aircraft or manual pesticide application. The pesticide application deviation is large, the cost is high, and the requirements for the flight environment are harsh; while the efficiency of manual pesticide application is low, and person...

[0002] Different types of farmland crops have different plant heights during the growth period. Correspondingly, the required heights of pesticide spraying machinery are also different. The main body of the existing land-walking pesticide machinery frame is fixed at a certain height, which cannot be flexibly satisfied. The demand for pesticide application management of various crops. Take corn as an example. When it grows to a certain height, ordinary land-based medical equipment cannot travel in the corn field. At this time, the control of corn diseases and insect pests can only rely on aircraft or manual pesticide application. The pesticide application deviation is large, the cost is high, and the requirements for the flight environment are harsh; while the efficiency of manual pesticide application is low, and personnel need to enter the corn bushes to spray pesticides in hot weather, which may pose a threat to personal safety
