Fruit trees will be attacked by various pests and diseases during their growth. These pests and diseases will seriously affect the growth of fruit trees and the quality of the fruit. It is convenient to spray pesticides on the pest-affected parts of tall arbor forests during forest cultivation. The use of pesticides can effectively control the occurrence and spread of pests and diseases, protect the healthy growth of trees, and thus increase yield and quality.

[0003] In the Chinese patent application number 202320941081.X, entitled "A Garden Spraying Device", the nozzle of the device is fixed under the support rod, and multiple nozzles are evenly distributed on the side walls of the nozzle. The support rod can extend the nozzle to the far end of the garden, thereby increasing the spraying range. The spray frame drives multiple nozzles to move, thereby improving the working efficiency of the sprayer. However, the height of the device is relatively low and cannot be used to spray pesticides on taller crops and tree forests and fruit trees.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. A multi-angle spraying assembly is provided. The lifting pole is fixed by fixing bolts so that the device can be adjusted according to the height. The corresponding number of connecting male heads, rotating tubes, connecting gooseneck tubes, mounting tubes, spray guns and spray heads are installed according to the number of rows and columns of plants and the height of plants. The number of connecting gooseneck tubes is increased or decreased according to the height of the plants so that the liquid sprayed by the spray gun can act on higher field crops, arbor forests and fruit forests. The device can be flexibly adjusted as needed and has a wide range of applications. The connecting gooseneck tube has a bending shaping function. The device can adjust the curvature of the connecting gooseneck tube according to the shape of the tree crown. The distance between the spray gun nozzle and various parts of the crown is adjusted by adjusting the curvature of the connecting gooseneck tube, so that the distance between each spray gun nozzle and the target is basically the same. When spraying, the liquid sprayed by the spray gun can be sprayed more evenly on the surface of the target plant, reducing the atomized liquid from escaping into the air, thereby reducing the waste of liquid and achieving better spraying effect.

[0022] Under the driving action of the traction rope, the traction motor is controlled to drive the spraying frame to move along the moving rail. The liquid medicine in the medicine storage box enters the main medicine pipe under the conveying action of the booster pump. Part of the liquid medicine flows through the connecting male head and the rotating pipe into the connecting gooseneck pipe and the installation pipe, and is finally sprayed out through the spray gun, and the other part is sprayed out through the spray head. Driven by the traction motor, the liquid medicine sprayed by the spray gun acts on both sides of the target plant, and the liquid medicine sprayed by the spray head acts on the top of the target plant. The mutual cooperation between the spray gun and the spray head enables the device to spray medicine at multiple angles, and the spraying effect is good. At the same time, the swinging electric push rod drives the swinging plate and the guide rod to swing back and forth, and the guide rod drives the spray gun to swing back and forth at multiple angles. The swing of the spray gun enables the liquid medicine sprayed by the spray gun to act on the plant in a larger range, and the spraying effect is better.

[0023] When the swinging electric push rod drives the swinging plate to move back and forth, it also drives the linkage rod to move back and forth. The reciprocating movement of the linkage rod drives the limit head to move inside the stirring guide ear, pushing the stirring rod to rotate back and forth. The rotation of the stirring rod stirs the liquid inside the medicine storage box to ensure that the effective ingredients of the pesticide can be fully dispersed to various parts, resulting in better spraying effect.

[0024] 2. Equipped with an efficient medicine delivery component, the medicine liquid flows through the branch hose, three-way liquid box, medicine extraction hose, medicine extraction pump and medicine delivery hose into the medicine delivery tube, then flows through the opened supplementary valve and supplementary medicine tube, and finally flows into the medicine storage box through the medicine delivery head. Whenever the medicine storage box moves to the bottom of the next medicine delivery head, the medicine extraction pump starts, the adjacent supplementary valve opens, and the medicine liquid is delivered into the medicine storage box through the opened supplementary valve and supplementary medicine tube to replenish the medicine liquid inside the medicine storage box, so that the device can operate continuously and the spraying efficiency is high;

[0025] When the liquid medicine in a medicine storage barrel is used up, the sub-control valve on the top of the medicine storage barrel is closed, and the next sub-control valve is opened, and the liquid medicine is transported from other medicine storage barrels to the medicine storage box, so as to realize the uninterrupted transportation of the liquid medicine and ensure the working stability of the device. If the liquid medicine needs to be prepared, the clean water and pesticide can be transported to the empty medicine storage barrel for preparation, so as to ensure the working continuity of the device;

[0026] The rotating table can rotate to facilitate the placement of the medicine storage barrel. The high-pressure air output by the air pump flows through the air distribution box, the air supply hose and the air distribution cylinder, and is finally ejected through the one-way nozzle. The ejected high-pressure air stirs the liquid medicine inside the medicine storage barrel to prevent the precipitation of the active ingredients in the liquid medicine when spraying, ensuring that the active ingredients of the pesticide are fully dispersed to various parts, thereby achieving the best prevention and control effect.

[0027] To summarize, in the multi-angle spraying component, the traction motor is controlled to drive the spray gun to move, thereby realizing automatic spraying. In the efficient medicine delivery component, the medicine extraction pump and the corresponding replenishing valve are controlled to switch, so that the medicine liquid inside the medicine storage barrel can be continuously delivered into the medicine storage box for replenishment, so that the device can operate continuously. There is no need for manual entry into the production operation area to operate the spray gun to spray higher field crops, tree forests, fruit forests, etc., which reduces the intensity of manual labor, prevents manual inhalation of atomized pesticides, and protects the health of farmers.

A corresponding number of connecting male connectors 218, rotating tubes 219, connecting gooseneck tubes 220, installing tubes 221, medicine spraying guns 222 and spray heads 230 are installed according to the number of rows and columns and the height of target plants in the field, forest field and orchard, so that there are medicine spraying guns 222 on both sides of the plant, and the medicine spraying guns 222 on both sides facing each other are facing both sides of the plant. The connecting female connector 217 located at the top of the plant is installed with the spray head 230. The number of connecting gooseneck tubes 220 is increased or decreased according to the height of the plant so that the medicine sprayed by the medicine spraying gun 222 can act on the target position. The connecting valve 216 without the connecting male connector 218 and the spray head 230 is closed, and the connecting valve 216 connected to the connecting male connector 218 and the spray head 230 is opened.

[0056] Before spraying pesticides, the curvature of the connecting gooseneck tube 220 is adjusted according to the shape of the tree crown. The connecting gooseneck tube 220 has a shaping effect after being bent. By adjusting the curvature of the connecting gooseneck tube 220, the distance between the nozzle of the spray gun 222 and each part of the crown of the plant is adjusted, so that the distance between the nozzle of each spray gun 222 and the target is basically the same. When spraying pesticides, the liquid sprayed by the spray gun 222 can be evenly sprayed on the surface of the plant, and the spraying effect is better.

[0057] When spraying pesticides, the medicine storage barrel 305 is placed on the top of the rotating table 302, and the partition plate 304 separates the medicine storage barrel 305. The rotating table 302 can be rotated to facilitate the placement of the medicine storage barrel 305. The pesticide and clean water are mixed in proportion and transported to the inside of the medicine storage barrel 305. After stirring and mixing, the air separator 322 is placed inside the medicine storage barrel 305, and the air pump 319 is started. The high-pressure air output by the air pump 319 flows through the air separator box 320, the air supply hose 321 and the air separator 322, and finally sprayed out through the one-way spray head 323. The sprayed high-pressure air stirs the liquid medicine in the medicine storage barrel 305, prevents the effective ingredients in the liquid medicine from precipitating when spraying pesticides, and ensures that the effective ingredients of the pesticides are fully dispersed to various parts, so as to achieve the best prevention and control effect;

[0058] The traction motor 237 close to the medicine storage barrel 305 is a proximal traction motor 237, and the traction motor 237 far from the medicine storage barrel 305 is a distal traction motor 237;

[0059] The medicine delivery hose 313 is connected to one end of the medicine delivery tube 314, the filter head 310 is placed inside the medicine storage barrel 305, and the remote traction motor 237 is started. Under the connection and driving action of the traction rope 239, the remote traction motor 237 pulls the medicine spraying frame 211 to move, so that the medicine storage box 212 moves to the bottom of the first medicine delivery head 318 at one end of the medicine delivery tube 314, and the medicine pump 311 is started to open the sub-control valve 308 on the top of the medicine storage barrel 305, and open the replenishment valve 316 near the medicine storage box 212, and the medicine liquid flows through the branch hose 30 9. The three-way liquid box 307, the medicine extraction hose 312, the medicine extraction pump 311 and the medicine delivery hose 313 enter the medicine delivery tube 314, then flow through the opened replenishing valve 316 and the replenishing medicine tube 317, and finally flow into the medicine storage box 212 through the medicine delivery head 318. When the medicine liquid fills most of the medicine storage box 212, the medicine extraction pump 311 stops running, the first replenishing valve 316 is closed, the remote traction motor 237, the booster pump 213 and the swing electric push rod 225 are started, and the remote traction motor 237 drives the spraying frame 211 to move along the moving rail 206 The liquid medicine in the medicine storage box 212 enters the main medicine pipe 214 under the conveying action of the booster pump 213, and then enters the opened connecting valve 216. A part of the liquid medicine flows through the connecting male connector 218 and the rotating tube 219 into the connecting gooseneck tube 220 and the mounting tube 221, and finally is sprayed out through the spray gun 222, and the other part is sprayed out through the spray head 230. Driven by the traction motor 237, the liquid medicine sprayed by the spray gun 222 acts on both sides of the plant, and the liquid medicine sprayed by the spray head 230 acts on the top of the plant and the tree. The mutual cooperation between the spray head 22 and the spray head 230 enables the device to spray medicine at multiple angles, and the spraying effect is good. At the same time, the swinging electric push rod 225 drives the swinging plate 226 to swing back and forth, and the swinging plate 226 swings back and forth, which also drives the guide rod 229 to swing back and forth. The guide rod 229 is embedded in the swinging guide ear 224. The guide rod 229 drives the rotating tube 219 to swing back and forth, thereby driving the spray gun 222 to swing back and forth at multiple angles. The swinging of the spray gun 222 enables the sprayed liquid from the spray gun 222 to act on crops and trees in a wider range, and the spraying effect is better.

[0060] When the swinging electric push rod 225 drives the swinging plate 226 to move back and forth, it also drives the linkage rod 231 to move back and forth. The reciprocating movement of the linkage rod 231 drives the limit head 232 to move inside the stirring guide ear 234, thereby driving the stirring rod 233 to rotate back and forth. The rotation of the stirring rod 233 can stir the liquid medicine inside the medicine storage box 212, again ensuring that the active ingredients of the pesticide can be fully dispersed to various parts to achieve the best prevention and control effect;

[0061] Whenever the medicine storage box 212 moves to the bottom of the next medicine delivery head 318, the medicine pump 311 is started, the adjacent replenishing valve 316 is opened, and the medicine liquid is delivered into the medicine storage box 212 through the opened replenishing valve 316 and the replenishing medicine pipe 317, so as to replenish the medicine liquid inside the medicine storage box 212, so that the device can operate continuously and the spraying efficiency is high;

[0062] When the liquid medicine in a medicine storage barrel 305 is used up, the sub-control valve 308 on the top of the medicine storage barrel 305 is closed, and the next sub-control valve 308 is opened, and the liquid medicine is transported from other medicine storage barrels 305 to the medicine storage box 212, so that the liquid medicine is transported uninterruptedly, ensuring the working stability of the device. If the liquid medicine needs to be prepared, the clean water and pesticide are transported to the empty medicine storage barrel 305 for preparation, so as to ensure the working continuity of the device;

[0063] By controlling the traction motor 237 to drive the spray gun 222 to move, automatic spraying is achieved. By controlling the switch of the medicine pump 311 and the corresponding replenishing valve 316, the medicine liquid inside the medicine storage barrel 305 can be continuously delivered to the medicine storage box 212 to replenish the medicine liquid, so that the device can operate continuously. There is no need for manual entry into the production operation area to operate the spray gun 222 to spray the target plants, which reduces the intensity of manual labor, prevents manual inhalation of atomized pesticides, and protects the health of farmers.

[0064] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
