DETAILED DESCRIPTION

[0023] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments:

[0024] As Figures 1-5 shown, the utility model provides a garden maintenance sprayer, including liquid medicine tank 3, liquid medicine tank 3 top outside is provided with a plurality of level sensor one 7, liquid medicine tank 3 top right side front is provided with liquid inlet 1, liquid medicine tank 3 top right side rear is provided with press 2, liquid medicine tank 3 bottom is provided with self-balancing device 5, and self-balancing device 5 bottom is fixedly connected with transport plate car 4, and liquid medicine tank 3 left end lower part is provided with spray pipe 6.

[0025] Liquid medicine tank 3 is the core container of the whole sprayer, is used to store the liquid required for spraying and realizes the injection and ejection of liquid through liquid inlet 1, spray pipe 6, and level sensor one 7 can monitor the level state of liquid medicine tank 3 in real time, and press 2 can exert pressure on the liquid in liquid medicine tank 3, so that the liquid is sprayed through spray pipe 6 under the action of pressure, and self-balancing device 5 ensures that liquid medicine tank 3 always keeps the horizontal state when the sprayer is in different terrain environments, and in the spraying operation process, the liquid flows to the spray head through spray pipe 6 under the action of press 2, and finally is sprayed in the form of spray.

[0026] As Figure 2As shown, this utility model provides a technical solution for a garden maintenance sprayer: Preferably, the liquid tank 3 includes a tank body 37, with an inner stirring shaft 35 disposed at the center of the tank body 37. A stirring paddle head 34 is fixedly connected to the bottom end of the inner stirring shaft 35, and the top end of the inner stirring shaft 35 extends to the outer side of the top end of the tank body 37. An outer stirring shaft 32 is rotatably connected to the outer surface of the inner stirring shaft 35, and a stirring divider head 36 is fixedly connected to the bottom end of the outer stirring shaft 32. The top end of the outer stirring shaft 32 extends to the outer side of the top end of the tank body 37. The mixing head 36 is located above and parallel to the mixing head 34. The outer surface of the top of the mixing outer shaft 32 and the mixing inner shaft 35 are jointly provided with the mixing drive assembly 31. The bottom end of the mixing drive assembly 31 is fixedly connected to the middle of the top of the liquid tank body 37. The liquid tank body 37 is provided with a liquid outlet 33 at the lower left end. The inside of the liquid tank body 37 is connected to the liquid outlet 33 and the liquid inlet 1. The output end of the press 2 extends to the inside of the liquid tank body 37. The centers of the mixing outer shaft 32 and the mixing inner shaft 35 are on a straight line.

[0027] The liquid tank body 37 provides a space for the entire sprayer to contain liquid. The stirring drive assembly 31 can receive external power or other power sources and transmit power to the stirring inner shaft 35 and stirring outer shaft 32, so that they rotate at a certain speed and direction, thereby driving the stirring paddle head 34 and stirring dividing head 36 to stir the liquid in the liquid tank body 37. The liquid outlet 33 is the channel through which the liquid in the liquid tank body 37 flows out after being stirred evenly.

[0028] like Figure 3 As shown, this utility model provides a technical solution for a garden maintenance sprayer: Preferably, the stirring drive assembly 31 includes an assembly housing 311, the bottom end of which is fixedly connected to the top end of the liquid tank body 37. The outer surface of the stirring outer shaft 32 is rotatably connected to the bottom end of the assembly housing 311. A lower driven gear 316 is fixedly connected to the top side of the outer surface of the stirring outer shaft 32. An upper driven gear 317 is fixedly connected to the top side of the outer surface of the stirring inner shaft 35. A drive shaft 313 is provided on the left side of the stirring outer shaft 32. A drive motor 312 is provided at the top end of the drive shaft 313. The outer surface of the drive motor 312 is fixedly connected to the inside of the assembly housing 311. Two parallel drive gears 314 are fixedly connected to the outer surface of the drive shaft 313. The right side of the lower drive gear 314 is meshed with the left side of the lower driven gear 316. A steering transmission gear 315 is meshed between the upper drive gear 314 and the upper driven gear 317. The top end of the steering transmission gear 315 is rotatably connected to the inside of the assembly housing 311.

[0029] like Figure 3As shown, this utility model provides a technical solution for a garden maintenance sprayer: preferably, the diameter of the upper driven gear 317 is smaller than that of the lower driven gear 316, the upper driving gear 314, the steering transmission gear 315 and the upper driven gear 317 are on the same horizontal plane, and the lower driving gear 314 and the lower driven gear 316 are on the same horizontal plane.

[0030] Drive motor 312 drives drive shaft 313 to rotate synchronously under electric drive. Two parallel drive gears 314 rotate together with drive shaft 313. The right teeth of the lower drive gear 314 mesh with the left teeth of the lower driven gear 316, thereby transmitting the power of drive motor 312 to the lower driven gear 316, which drives the outer stirring shaft 32 to start rotating. The teeth of the upper drive gear 314 mesh with the upper driven gear 317 through steering transmission gear 315. Since the diameter of the upper driven gear 317 is smaller than that of the lower driven gear 316, according to the gear transmission principle, under the same driving conditions, the inner stirring shaft 35 will obtain a higher speed than the outer stirring shaft 32, and the two rotate in opposite directions through steering transmission gear 315.

[0031] like Figure 4 As shown, this utility model provides a technical solution for a garden maintenance sprayer: Preferably, the self-balancing device 5 includes a sliding track 52, which is cross-shaped. A support base 54 is fixedly connected to the top center of the sliding track 52. A movable positioning plate 53 is provided between every two adjacent sides of the sliding track 52. A movable groove is provided at one end of the sliding track 52 near the movable positioning plate 53. The bottom end of the sliding track 52 is fixedly connected to the top of the transport trolley 4. A balance telescopic foot 51 is fixedly connected to the top center of the movable positioning plate 53. The top of the balance telescopic foot 51 is fixedly connected to the bottom of the liquid tank body 37. Several level sensors 55 are fixedly connected to the outside of the transport trolley 4.

[0032] The sliding track 52 serves as the basic support structure, and its cross-shaped design provides a stable framework for the entire balance adjustment system. The support base 54 is used to support the medicine tank 3 when not balancing. When the balance telescopic foot 51 extends or retracts, the angle between it and the bottom of the medicine tank 3 changes. To adapt to the angle change, the movable positioning plate 53 needs to slide in the moving groove of the sliding track 52. The sliding distance between the movable positioning plate 53 and the sliding track 52 is proportional to the extension or retraction length of the balance telescopic foot 51. The balance telescopic foot 51 directly supports the medicine tank 3 and adjusts its height. The second horizontal sensor 55 can calculate the tilt state of the device by comparing data with the first horizontal sensor 7, thereby controlling the extension or retraction of the balance telescopic foot 51 to adjust it to a horizontal state for the medicine tank 3.

[0033] like Figure 5As shown, this utility model provides a technical solution for a garden maintenance sprayer: preferably, the movable positioning plate 53 includes a movable plate 531, a movable ball bearing 532 is movably connected to the middle of the bottom end of the movable plate 531, and a movable guide rib 533 that can enter the movable groove is fixedly connected to the middle of the end of the movable plate 531 near the sliding track 52.

[0034] The movable plate 531 serves to connect and support other components. The movable ball bearing 532 mainly supports the movable plate 531 while reducing the friction between the movable plate 531 and the top of the transport plate 4. The movable guide rib 533 cooperates with the movable groove to limit the movement range of the movable plate 531, so that the movable plate 531 remains connected to the sliding track 52 while adapting to the appropriate position.

[0035] like Figure 5 As shown, this utility model provides a technical solution for a garden maintenance sprayer: Preferably, the balance telescopic foot 51 includes a support connecting seat 514, the bottom end of which is fixedly connected to the middle of the top of the moving plate 531. A hydraulic telescopic rod 513 is fixedly connected to the top of the support connecting seat 514, and an angle-adapting ball 512 is fixedly connected to the top of the hydraulic telescopic rod 513. A connecting limiting block 511 is rotatably connected to the upper side of the outer surface of the angle-adapting ball 512. The top of the connecting limiting block 511 is fixedly connected to the bottom of the liquid tank body 37, and the bottom of the connecting limiting block 511 covers two-thirds of the outer surface of the angle-adapting ball 512.

[0036] The support connecting seat 514 can transmit force and provide support, so that the movement of the movable positioning plate 53 can effectively drive the overall position adjustment of the balance telescopic foot 51. During the operation of the sprayer, when the terrain of the transport cart 4 changes and causes the liquid tank 3 to tilt, the hydraulic telescopic rod 513 can extend and retract under the control of the control system according to the signal transmitted by the horizontal sensor 55. When the hydraulic telescopic rod 513 extends and retracts, the angle between it and the liquid tank body 37 will change. The angle adapting ball 512 can rotate freely within a certain range of the connecting limit block 511 to adapt to the angle change between the liquid tank 3 and the balance telescopic foot 51. At the same time, because the rotation range of the angle adapting ball 512 within the connecting limit block 511 is limited, and the movement distance of the movable positioning plate 53 is proportional to the angle, the connecting limit block 511 can prevent the movable positioning plate 53 from moving excessively and disengaging from the sliding track 52.

[0037] The working principle of this type of garden maintenance sprayer will be explained in detail below.

[0038] like Figures 1-5As shown, the raw materials such as pesticides, fertilizers and water are injected into the liquid tank body 37 through the liquid inlet 1, the stirring drive assembly 31 is started, the drive motor 312 drives the driving shaft 313 to rotate, the driving gear 314, the steering transmission gear 315, the upper driven gear 317 and the lower driven gear 316 are driven to rotate, the stirring inner shaft 35 and the stirring outer shaft 32 rotate in opposite directions at different speeds, the stirring paddle 34 and the stirring split head 36 are controlled to fully and uniformly stir the liquid, the press 2 is started, the liquid in the liquid tank body 37 is pressurized, the spray pipe 6 switch is opened to start spraying, the horizontal sensor one 7 and the horizontal sensor two 55 are monitored in real time, when the transport plate car 4 is in uneven terrain, the horizontal sensor two 55 senses the inclination and compares with the horizontal sensor one 7, the signal is transmitted to the control system, the hydraulic telescopic rod 513 of the balance telescopic foot 51 is controlled to extend or retract, the position adjusting plate 53 moves on the sliding rail 52 to adjust the position, the angle adjusting ball 512 adjusts the angle change, the pesticide liquid tank 3 is kept horizontal, and uniform spraying is ensured.

[0039] The above is a detailed description of the utility model, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
