[0027] As shown in Figures 1-4 A high-coverage frost-proof automatic spraying device, comprising a water storage tank (not shown in the figure), a water pump and a spraying system. The water storage tank is used to store water to provide water source for the whole spraying process. The water pump is installed on the water storage tank, and the water outlet end thereof is communicated with the spraying system, which is responsible for conveying the water in the water storage tank to the spraying system.

[0028] The spraying system comprises a spraying device and a height adjusting device.

[0029] As Figure 3 , Figure 4 The spraying device comprises a water delivery pipe (not shown in the figure) in communication with the water pump, and an inner pipe 24 is communicated at the end of the water delivery pipe away from the water pump. Figure 3 、 Figure 4 The outer pipe 25 is rotatably sleeved outside the inner pipe 24, specifically, one end of the outer pipe 25 is rotatably and sealingly connected with the inner pipe 24, and the other end is provided with a nozzle assembly whose water spraying direction is coincident with the vertical horizontal plane.

[0030] As Figure 4 Specifically, the driving device comprises a second motor 26 fixed on the outer surface of the inner pipe 24, and a driving gear 27 is fixedly sleeved on the output shaft of the second motor 26.

[0031] The outer pipe 25 is fixedly sleeved with a driven gear 28 engaged with the driving gear 27. When the second motor 26 is started, its rotation drives the driving gear 27 to rotate, and the engagement of the driving gear 27 and the driven gear 28 drives the outer pipe 25 to rotate, thereby driving the nozzle assembly to start rotating.

[0032] As Figure 1 、 2As shown, the height adjusting device comprises a mounting plate 11, a vertically arranged screw rod 12 is rotatably connected to the mounting plate 11, and a vertically arranged light rod 13 is also fixedly connected to the mounting plate 11. A bearing plate 14 is arranged at the top of the screw rod 12 and the light rod 13, and the bearing plate 14 is rotatably connected to the screw rod 12 and fixedly connected to the light rod 13. A first motor 17 is mounted on the bearing plate 14, and the output shaft of the first motor 17 is fixedly connected to the screw rod 12. The height adjusting device further comprises a sliding block 21, which is threadedly connected to the screw rod 12 and slidably connected to the light rod 13, and the spraying device is mounted on the sliding block 21. When the first motor 17 rotates, the screw rod 12 is driven to rotate. Since the sliding block 21 is threadedly connected to the screw rod 12, the sliding block 21 will move up and down on the screw rod 12, thereby achieving adjustment of the height of the spraying device. Such design can adapt to crops of different heights, such as peanuts, sweet potatoes, sugarcane, corn and the like. Protective shells 16 are arranged between adjacent spraying devices, the protective shells 16 are clamped between adjacent spraying devices and move with the spraying devices, thereby protecting the screw rod 12 and keeping the surface of the screw rod 12 clean.

[0033] As shown in Figure 3 , Figure 4 To adjust the spraying direction of the spraying device, the following design is made: the sliding block 21 comprises a sliding block body and a rotating sleeve 22 (specifically, limit plates are mounted on the upper and lower surfaces of the sliding block body, and the rotating sleeve is sleeved on the outer surface of the sliding block body and located between the two limit plates) rotatably sleeved on the outer surface of the sliding block 21. The rotating sleeve 22 and the sliding block body are in high-damping sliding connection, and the relative position of the rotating sleeve 22 and the sliding block body will not change without human intervention after the rotating sleeve 22 is adjusted to a preset position. The inner tube 24 of the spraying device is detachably connected to the rotating sleeve 22. By rotating the rotating sleeve 22, the position of the spraying device can be adjusted, so that the spraying device sprays at different positions in the horizontal plane, further increasing the spraying coverage. The rotating sleeve 22 is fixedly provided with a fixed block 23, an installation hole is formed in the middle of the fixed block 23, and the inner tube 24 is threadedly connected to the installation hole. This detachable connection facilitates maintenance of the spraying device. At the same time, the rotating direction of the outer tube 25 is the direction in which the inner tube 24 is tightened in the fixed block 23, preventing the inner tube 24 from loosening and coming out of the fixed block 23 during use.

[0034] The bearing plate 14 is provided with a visual sensor 15, and the mounting plate 11 is provided with a temperature sensor (not shown in the figure, and the temperature sensor is arranged on the mounting plate 11, because the cold air in the environment temperature is easy to sink, so the temperature sensor detects the temperature of the lower part of the field, when the lower temperature is above the preset temperature, the temperature of the upper part of the field will also be higher than the preset temperature), and the controller is electrically connected with the first motor 17 and the second motor 26. The visual sensor 15 is used for detecting the height of crops, and transmitting information to the controller, and the controller controls the first motor 17 to rotate according to the received information, and drives the spraying device to move up and down; and when the temperature sensor senses that the environmental temperature is lower than the preset value, the water pump (the water pump works intermittently according to the preset control program in the controller, to save water) is started, and the second motor 26 starts to work, and the nozzle assembly starts to rotate and spray water; at the same time, the visual sensor 15 can also detect the frost condition on the surface of crops, if the surface of crops starts to frost, the information is transmitted to the controller, and the controller controls the water pump to increase the water supply according to the received information, and the frost treatment is carried out on the crops, if the surface of crops does not show frost phenomenon, the water pump can keep normal water supply, and frost prevention can be carried out, through the cooperation of the temperature sensor, the visual sensor 15, the controller and other electrical appliances, the purposes of automatic water mist frost prevention and water resource saving are achieved.

[0035] The use principle of the embodiment is as follows:

[0036] When it is necessary to prevent frost and spray crops, the water pump is started, the water in the water storage tank is transported to the inner pipe 24 through the water delivery pipe, and then enters the nozzle assembly. At the same time, the second motor 26 is started, which drives the outer pipe 25 and the nozzle assembly to rotate, and the water mist is sprayed from the atomizing nozzle 292 of the nozzle assembly. In the vertical horizontal plane, with the rotation of the nozzle assembly, the centrifugal force is used to make the water mist spray farther, and can be sprayed in 360° direction, and the crops are sprayed in all directions.

[0037] The temperature sensor, the visual sensor 15, the controller and other electrical appliances in the device cooperate with each other, and automatically carry out water mist frost prevention and control water quantity.
