Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Figures 1 to 3 An automatic spraying device according to an embodiment of the utility model comprises:

[0040] The spray assembly 1 includes a liquid storage tank 11, a spray pump 12 disposed in the liquid storage tank 11 for conveying liquid, and a spray pipe 13 disposed on both sides of the liquid storage tank 11, wherein the spray pipe 13 is provided with a plurality of spray heads 131;

[0041] The vehicle body 2 includes a frame 21 for carrying the spray assembly 1, a wheel assembly 22 disposed under the frame 21, and a driving assembly for driving the wheel assembly 22;

[0042] Track 3: set on the ground, the wheel assembly 22 cooperates with the track 3, so that the vehicle body 2 moves along the track 3;

[0043] Liquid adding component 4: arranged at the end of the track 3, when the vehicle body 2 moves to the end of the track 3, the liquid adding component 4 injects water into the liquid storage tank 11;

[0044] Control component: includes several timers, which are electrically connected to the spray pump 12, the drive component and the liquid adding component 4 to control the spraying time, the movement time and the liquid filling time.

[0045] In an embodiment of the utility model, the track 3 is laid according to a preset route, so that the vehicle body 2 runs along the track 3, and the start and stop of the vehicle body 2 and the opening and closing of the spraying component 1 are controlled by the control component to realize automatic liquid spraying on the planting area, and the liquid adding component 4 set at the end of the track 3 can add liquid as needed.

[0046] Specifically, the liquid storage tank 11 includes a box frame 111 and a liquid storage bag 112. The liquid storage bag 112 is made of a flexible material and is fixed in the box frame 111. The box frame 111 maintains the spatial structure. The box frame 111 is composed of detachable rods. This solution is adopted from the perspective of reducing the cost and facilitating the adjustment of the volume of the liquid storage tank 11: the liquid storage bag 112 can be made of plastic material or rainproof cloth and other materials. The device requires a lot of spraying liquid. Specially customized hard plastic barrels or metal barrels are expensive and heavy, which further affects the requirements for the laying of the track 3, resulting in an increase in the cost of the entire system. The detachable rods can be stainless steel lean pipes and corresponding accessories commonly used in industrial assembly lines. The frame made of this material is firm, easy to assemble, and can be reused. If the volume of the liquid storage tank 11 is to be adjusted, the internal volume can be simply changed by changing a certain value of the length, width, and height, thereby reducing the cost.

[0047] Optionally, the spray pipe 13 includes a spray lower pipe 132 and a spray upper pipe 133, which are threaded together. The spray lower pipe 132 is fixed to the frame 21, one end of which is connected to the liquid outlet of the spray pump 12, and the other end is provided with a spray upper pipe 133; the spray head 131 is provided on the spray upper pipe 133. The advantage of adopting this solution is that when the layout of the planting area changes and the planting height is adjusted, it is not necessary to replace the entire spray pipe 13, but it can be directly extended by superimposing the spray upper pipe 133, and this structure is also helpful for cleaning the inside of the spray pipe 13. Furthermore, the nozzle of the spray upper pipe 133 can be directly fixed, or it can be movably provided on the spray upper pipe 133 by means of threaded connection, etc., to facilitate replacement.

[0048] In combination with the solution that the liquid storage bag 112 is made of flexible material, the spray lower pipe 132 is provided with a branch pipe 1321, which extends into the liquid storage bag 112 from the top opening, and the liquid is pumped into the pipe by the spray pump 12, and further pressurized and transported to the spray head 131.

[0049] Optionally, the cross-section of the track 3 is a round tube, and the wheels in the corresponding wheel assembly 22 are concave wheels. This solution can reduce system costs and facilitate promotion and use. Compared with the common I-beam track 3, although the round tube has a smaller load-bearing capacity, the material is easy to obtain and the laying requirements are low. Compared with the channel steel track 3, the round tube is not easy to accumulate water and rust.

[0050] In an embodiment of the utility model, the wheel assembly 22 can be an independent front wheel to facilitate steering, and the rear wheel forms a mechanical transmission with the drive assembly through a speed change mechanism, with the rear wheel driven and the front wheel guided. The frame 21 can be a bottom plate structure similar to a trolley, and can be pushed manually when necessary.

[0051] The drive assembly can include a motor and a battery pack, so that it can operate without the constraints of cables, or it can be powered by an external input power source through a hanging cable to maintain the operation of the device.

[0052] Optionally, the liquid adding component 4 includes a liquid adding switch 41. When the vehicle body 2 runs to the set position, the liquid adding switch 41 is touched to allow the liquid adding component 4 to be filled with liquid. Specifically, the liquid adding switch 41 is set at a height that can be touched by the vehicle body 2. When the vehicle body 2 hits the liquid adding switch 41, the liquid adding component 4 starts to inject liquid. The liquid adding component 4 includes a liquid adding pump, a liquid adding pipe and a corresponding storage tank. The liquid adding pump is controlled by the liquid adding switch 41. Since the volume of the liquid storage tank 11 is fixed, the consumption is fixed after the spraying time is fixed, and the liquid adding time can also be fixed.

[0053] Optionally, the control component also includes a PLC, which controls the timer. The PLC is set on the vehicle body 2 and can be connected to a liquid level sensor set in the liquid storage tank 11. When the liquid level is lower than a set value, the PLC receives the sensor information and drives the vehicle body 2 to run directly to the liquid filling position. When the liquid is filled to a set volume, the PLC controls to stop adding liquid and continue the spraying operation.

[0054] In some embodiments, a liquid level control system is also included, and the liquid level control system includes a wireless water level monitoring component arranged in the liquid storage tank, and a water level monitoring signal receiving component arranged in the liquid adding component. Specifically, the wireless water level monitoring component may include a signal transmitter and a water level probe, wherein the water level probe is arranged in the liquid storage 11, and the signal transmitter transmits the signal according to the signal it senses; and the water level monitoring signal receiving component includes a signal receiver, and a water level setting controller, wherein the signal receiver receives the water level signal from the signal transmitter and then transmits it to the water level setting controller. According to the preset parameters, the water level setting controller can decide whether to add water when the vehicle body reaches the end of the track next time, and whether the amount of water added reaches the set value, so that the water adding process can be further intelligentized. It is also possible to directly recall the vehicle body to add water when necessary by connecting to the above-mentioned PLC to realize full automation throughout the entire process.
