Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, in particular to a pesticide spraying vehicle. Background Art

[0002] In the process of agricultural production, pesticides need to be sprayed on the crops. Pesticide spraying vehicles are a type of agricultural equipment, mainly used for spraying pesticides in farmland, orchards, forests and other places to prevent and control various pests and diseases. Pesticide spraying vehicles are divided into large automatic spraying vehicles and small manual spraying vehicles. Small planting areas generally use manual pushcart-shaped spraying vehicles. However, most pesticide spraying vehicles on the market have too simple spraying structures. When spraying pesticides over a large area, it is often necessary to spray pesticides in multiple areas multiple times. When spraying pesticides over a small area, the spraying structure is not easy to enter, and the operation is very inconvenient.

[0003] For example, a pesticide spraying vehicle with patent application number CN202322126246.0 discloses "comprising a vehicle frame, a medicine barrel and a medicine spraying rod, wherein a medicine barrel and a water pump are fixedly connected to the upper end of the vehicle frame, the medicine barrel and the water pump are fixedly connected via a water pipe, the water outlet of the water pump is fixedly connected to the medicine spraying rod via a water pipe, an upper cover is spirally connected to the upper end of the medicine barrel, an air hole is provided on the inner side of the upper cover, a limit block and a guide rod are fixedly connected to the inner wall of the medicine barrel, the guide rod is slidably connected to a first buoyancy plate via a limit groove, a first through hole and a hollow hole are provided on the inner side of the first buoyancy plate, a rotating shaft is provided on the inner side of one end of the first buoyancy plate The rotating groove is provided with a card slot at one end. In the utility model, when the liquid level of the medicine barrel is low, the pesticide inside the medicine barrel can be prevented from shaking greatly, thereby ensuring the stability of the water pump, and effectively improving the uniformity of the spraying rod, and further improving the uniformity of the pesticide spraying. "Although the above structure can realize the spraying function of pesticides, since the length of the spraying rod is fixed and the spraying angle of the spraying rod is also fixed, when spraying pesticides on some small plots or small areas, it is easy to spray the pesticides outside the plots or beyond the range where the pesticides need to be sprayed, which is extremely inconvenient to use and has low applicability.

[0004] In order to solve the above problems, we provide a pesticide spraying vehicle that can realize pesticide spraying, and can spray pesticides on smaller plots or plots with smaller spraying areas as needed, and can increase the spraying area as needed. Utility Model Content

[0013] When a large area of ​​land needs to be sprayed, the rotating motor is used to drive the rotating water spray pipes on the left and right sides to rotate, and the rotating water spray pipes on both sides are unfolded to increase the spraying range; then the solenoid valves on the left and right ends of the fixed water spray pipes are opened to allow the pesticide solution to enter the rotating water spray pipes on the left and right sides, and the pesticide is sprayed through the nozzles evenly distributed on the fixed water spray pipes and the rotating water spray pipes to achieve large-scale pesticide spraying. After the rotating water spray pipes are unfolded, the power of the water pump can be adjusted as needed to ensure the spraying effect.

At the same time, according to needs, the extension of the telescopic electric cylinder 1 can cooperate with the extension of the telescopic electric cylinder 2 to change the distance between the fixed water spray pipe and the rotating water spray pipe and the rear end face of the carrier.

[0015] The rotating water spray pipe on one side can also be unfolded separately as needed, and the solenoid valve on the corresponding side can be opened to control the power of the water pump to adapt to the range of pesticide spraying. When the rotating water spray pipes on both sides do not need to be unfolded, they can be stored, that is, the rotating motor drives the rotating water spray pipe to rotate, so that the slot on the card plate on the rotating water spray pipe is inserted into the corresponding card pin, and the card pin and the upper and lower parts of the card slot of the card plate are clearance-matched to prevent the rotating water spray pipe from shaking up and down during the movement of the carrier.

[0016] The control of the electrical components in the above technical solution is the prior art, and it is sufficient to realize the functional control of the above electrical components without specific technical restrictions. At the same time, the above electrical components are also the prior art, and suitable specifications and models can be selected as needed without technical restrictions.

[0028] The fixed water spray pipe 5 is connected to the rotating water spray pipe 3 via a hose 12 to adapt to the function of the rotating water spray pipe 3 when rotating.

[0029] The two ends of the connecting rod are respectively provided with a rotating motor 6, and the output end of the rotating motor 6 is provided with a rotating disk, which is fixedly connected to the rotating water spray pipe 3. A clamping plate 11 is provided on each rotating water spray pipe 3, and a clamping groove is provided on the side of the clamping plate 11; two clamping pins 10 are fixedly provided on the rear side of the connecting rod, and when the rotating water spray pipe 3 rotates to be parallel to the connecting rod, the clamping pins 10 are clamped into the clamping groove of the clamping plate 11.

Since rotating water spray pipes 3 are provided on both the left and right sides, in order to avoid interference during storage of the rotating water spray pipes 3, the sizes of the turntables driven by the rotating motor 6 are inconsistent, and the rotating water spray pipes 3 are fixed to the outer ends of the turntables, so that one of the turntables drives the corresponding rotating water spray pipe 3 to be stored to a position adjacent to the fixed water spray pipe 5; the other turntable drives the corresponding rotating water spray pipe 3 to be stored to the outside, so as to realize the storage of the two rotating water spray pipes 3.
