[0019] Example 1

[0020] like Figures 1 to 4 As shown, this utility model proposes an automatic orchard spraying device, including a spraying device body 1, a spray tank 3, a limiting mechanism, a tank cover 4, and a three-way valve 15. Two sets of first support frames 2 are provided at the top of the spraying device body 1. The spray tank 3 is rotatably connected to the top of the two sets of first support frames 2 via bearings. The limiting mechanism is located between the spraying device body 1 and the spray tank 3, limiting the spray tank 3 to the spraying device body 1. The tank cover 4 is detachably connected to the top of the spray tank 3. Both the spray tank 3 and the tank cover 4 are provided with lugs 5, and the corresponding lugs 5 are connected by a locking mechanism. The locking mechanism is existing technology, and those skilled in the art can select appropriate locking mechanisms for installation as needed. The three-way valve 15... The second support frame 16 is connected to the main body 1 of the spraying device. The output end of the three-way valve 15 is connected to the water pump 20 on the main body 1 of the spraying device via a detachable hose. The output end of the water pump 20 is connected to the atomizing nozzle. The water pump 20, the atomizing nozzle, and the mechanism for adjusting the height of the atomizing nozzle are all prior art. The specific structure and principle are detailed in the patent with publication number CN118177174A, and will not be repeated here. One set of input ends on the three-way valve 15 is connected to the medicine tank 3 via a hose, and the other set of input ends on the three-way valve 15 is connected to the external cleaning fluid via a hose. The main body 1 of the spraying device is provided with a conduit for storing the hose, which is prior art.

[0021] Furthermore, the limiting mechanism includes a locking box 11, an abutment plate 13, and a connecting seat 8; the locking box 11 is installed on the side of the main body 1 of the spraying device, and a limiting port is opened at the top of the locking box 11; the abutment plate 13 slides along the height direction of the inner wall of the locking box 11 and is elastically connected to the locking box 11, the abutment plate 13 abuts against the top of the locking box 11, and a first elastic element 14 is provided between the abutment plate 13 and the bottom of the locking box 11, the first elastic element 14 being a spring; the connecting seat 8 is installed on the side wall of the medicine tank 3, an adjusting rod 9 is movably inserted into the connecting seat 8, a locking plate 10 is installed at the bottom of the adjusting rod 9, the locking plate 10 matches the limiting port, and an anti-slip pad is provided at the top of the locking plate 10;

[0022] Furthermore, the limiting port is composed of a second port 19 and two sets of first ports 12 symmetrically distributed on the side of the second port 19. The adjusting rod 9 is in contact with the second port 19, and the locking plate 10 is in contact with the first port 12.

[0023] In an optional embodiment, in the initial state, the locking plate 10, under the elastic force of the first elastic member 14, is pressed against the top of the locking box 11 by the abutment plate 13. The locking plate 10 is perpendicular to the limiting port, and the adjusting rod 9 abuts against the second port 19. An appropriate amount of pesticide is injected into the pesticide tank 3 through the liquid inlet valve on the lid 4. The main body 1 of the spraying device moves the device to the vicinity of the fruit tree, and opens the output end of the three-way valve 15 and a set of input valves corresponding to the pesticide tank 3. The controller starts the water pump 20 to extract the pesticide from the pesticide tank 3 and transport it to the fruit tree. The atomizing nozzle sprays the pesticide onto the fruit trees. When it's time to change to another pesticide after spraying, press the adjusting rod 9 down along the connecting seat 8, causing the abutment plate 13 to slide down along the locking box 11. At the same time, the first elastic element 14 is compressed. Then, rotate the adjusting rod 9 along the connecting seat 8 until the locking plate 10 rotates along the abutment plate 13 to align with the second opening 19 and the first opening 12. Then, release the pressure on the adjusting rod 9. Under the elastic force of the first elastic element 14, the abutment plate 13 moves upward along the locking box 11, which in turn moves the locking plate 10 upward. Until it passes through the limiting port and separates from the locking box 11, the medicine barrel 3 loses its limiting position from the main body 1 of the spraying device. Rotate the medicine barrel 3 downwards along the two sets of first support frames 2 until the side wall of the medicine barrel 3 abuts against the edge of the main body 1 of the spraying device. Open the latch between the lid 4 and the medicine barrel 3. Hold the handle on the lid 4 and lift the lid 4 and the stirring mechanism on it to separate them from the medicine barrel 3. Once the stirring mechanism is separated from the medicine barrel 3, the inside of the medicine barrel 3, the lid 4, and the stirring mechanism can be rinsed to avoid medicine residue. Then, turn on the three-way valve 15, away from the medicine barrel 3. The hose at the end is connected to the external cleaning fluid, and its valve is opened while the valve corresponding to the medicine tank 3 is closed. The water pump 20 is started to draw in the external cleaning fluid. The cleaning fluid passes through the water pump 20 and is then sprayed out by the atomizing nozzle, which can clean the residual medicine and prevent contamination of subsequent medicine. It should be noted that the residual medicine in the hose between the three-way valve 15 and the medicine tank 3 can be removed by injecting a small amount of tilting liquid into the medicine tank 3 when the medicine tank 3 is perpendicular to the main body 1 of the spraying device. The cleaning fluid is then drawn out by the water pump 20, and the cleaning fluid flows through this set of hoses to flush away the residual medicine.

[0024] Example 2

[0025] like Figure 1 and Figure 3As shown, the automatic orchard spraying device proposed in this utility model differs from Embodiment 1 in that: two sets of limiting rods 7 are symmetrically installed on the barrel cover 4, and two sets of limiting seats 6 are symmetrically installed on the outer circumference of the medicine barrel 3. The limiting rods 7 are movably inserted into the corresponding limiting seats 6. The limiting rods 7 are composed of reinforcing rods and nuts connected to the reinforcing rods. The nuts are threadedly connected to the end of the reinforcing rods away from the barrel cover 4.

[0026] In an optional embodiment, the setting of two sets of limiting rods 7 allows the lid 4 to be pulled along the outer wall of the medicine barrel 3 after it is separated from the medicine barrel 3. This exposes the stirring mechanism on the lid 4 to the outside of the medicine barrel 3 for easy rinsing, without the need to completely disassemble the lid 4 and the stirring mechanism from the medicine barrel 3. This reduces lifting work and facilitates cleaning. After cleaning, it also makes it easier to install the lid 4 and the medicine barrel 3. When the stirring mechanism needs to be inspected, the nut can be separated from the reinforcing rod to completely separate the medicine barrel 3 from the lid 4, making it convenient to inspect the stirring mechanism.

[0027] Example 3

[0028] like Figure 4 As shown, the automatic orchard spraying device proposed in this utility model differs from Embodiment 1 in that: the main body 1 of the spraying device is provided with a buffer assembly corresponding to the pesticide tank 3. The buffer assembly consists of multiple sets of second elastic elements 18 installed on the main body 1 of the spraying device and a buffer seat 17 installed between the top ends of the multiple sets of second elastic elements 18. The second elastic element 18 consists of a telescopic rod and a spring movably sleeved on its outside. The top ends of the telescopic rod and the spring are connected to the buffer seat 17, and the bottom ends of the telescopic rod and the spring are connected to the main body 1 of the spraying device.

[0029] Furthermore, the top of the buffer seat 17 is provided with an arc-shaped part, which corresponds to the medicine barrel 3, and a corresponding rubber pad is provided on the arc-shaped part.

[0030] In an optional embodiment, when the medicine barrel 3 rotates along the two sets of first support frames 2 to tilt the top of the medicine barrel 3 downward, the buffer seat 17 supports the side wall of the medicine barrel 3. The rubber pad and the second elastic element 18 can buffer the medicine barrel 3 to prevent it from suddenly colliding with the body 1 of the spraying device, reduce damage, and extend its service life.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
