[0002] In the agricultural fruit tree planting, it is necessary to spray the fruit trees with pesticides and apply fertilizers on the leaves to prevent and control fruit tree diseases and pests and supplement nutrition. The current spraying and fertilizing devices mostly use backpack-type medicine boxes to hold the spray or drag long tubes to hold the spray. This method is inefficient, labor-intensive, and wastes a lot of pesticides and fertilizers. Since the staff stand under the tree and spray upward at an angle, the top cannot be sprayed evenly. At the same time, manual spraying cannot control the spraying amount. Excessive spraying will affect the environment and fruit trees. Summary of the invention

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] like Figure 1-5 As shown, an agricultural machine for spraying pesticides and fertilizing fruit trees includes a cart 1, a positioning plate 2 is bolted to the cart 1, an electric cylinder 3 is installed on the positioning plate 2, an arc guide rail 4 is fixed to the output end of the electric cylinder 3, a slider 5 is slidably connected to the arc guide rail 4, an arc support rod 6 is fixed to the slider 5, lower support rods 7 are fixed at both ends of the arc support rod 6, a middle support rod 8 is sleeved on the lower support rod 7, an upper support rod 9 is sleeved on the middle support rod 8, a spray pipe 10 is detachably installed on the lower support rod 7, a plurality of spray heads 11 are installed on the spray pipe 10, two spray pipes 10 are connected in parallel and connected to a rotary joint 12, and the rotary joint 12 is fixed to the lower support rod 7 close to the slider 5. The spray pipe 10 can be fixed by using a pipe clamp, which is threadedly connected to the middle support rod 8 and the upper support rod 9. For example, a plurality of thread holes are opened on the middle support rod 8 for threading the pipe clamp, which does not hinder the adjustment of the position of the upper support rod 9. If necessary, the pipe clamp can be removed and adjusted.

[0028] A medicine box 13, an electric control box 14, and an electric pump 15 are fixed on the cart 1. A plurality of wheels 16 are installed at the bottom of the cart 1. The input end of the electric pump 15 is connected to the medicine box 13 pipeline, and the output end of the electric pump 15 is connected to the rotary joint 12 through a hose 28. A groove 17 is provided in the middle of the cart 1. A push handle 18 is provided at one end of the cart 1, and a plurality of control buttons 19 are installed on the push handle 18. When the slider 5 moves, the hose 28 rotates relative to the spray pipe 10. If a single pipe is used, the pipe will be self-twisted, which is easy to damage the pipe. The rotary joint 12 can connect a pipe with one end rotating and the other end stationary, thereby preventing the spray pipe 10 from self-twisting during the movement of the slider 5. At the same time, the hose 28 can follow the movement of the slider 5 for self-adaptation.

[0029] The positioning plate 2 is inserted into the groove 17. The positioning plate 2 is provided with a plurality of positioning holes 20. The positioning plate 2 is bolted to the groove 17 of the cart 1 through the positioning holes 20. The end of the positioning plate 2 away from the cart 1 has an arc-shaped notch 21. The wheel 16 is installed at the bottom of the end of the positioning plate 2 with the notch 21. The electric cylinder 3 is installed above the end of the positioning plate 2 with the notch 21. The positioning plate 2 can slide in the groove 17 to adjust the distance of the positioning plate 2 protruding from the cart 1. When not in use, the protruding distance is shortened to reduce the occupied space.

[0030] The arc guide rail 4 and the arc support rod 6 are both arc-shaped, and the arc structures of the arc guide rail 4, the arc support rod 6 and the notch 21 are coaxial, and the opening positions of the arc guide rail 4, the arc support rod 6 and the notch 21 are all facing the same direction. A plurality of rollers 22 are installed at the bottom of the arc support rod 6, and the bottom ends of the rollers 22 abut against the top of the arc guide rail 4. In this way, when the trunk of the fruit tree is stuck in the notch 21 from the opening of the notch 21, the trunk is also located in the arc guide rail 4 and the arc support rod 6, thereby completing the positioning, and the slider 5 can rotate half a circle around the trunk.

[0031] Vertical plates 23 are fixed to the sides of both ends of the arc-shaped guide rail 4, and proximity switches 24 are installed on the two vertical plates 23. A baffle 25 is fixed to the slider 5, and the moving track of the baffle 25 passes through the triggering points of the two proximity switches 24. The proximity switches 24 are used to control the stroke of the slider 5. When the slider 5 moves from one end to the other end, it cannot move further. At this time, it touches the corresponding proximity switch 24 and returns. It returns to the starting position and stops after touching the corresponding proximity switch 24. This can prevent the hose 28 from being wrapped around the electric cylinder 3.

[0032] The electric cylinder 3, the electric pump 15, the proximity switch 24, the control button 19, and the slider 5 are all electrically connected to the electric control box 14. The control button 19 has buttons for controlling the opening and closing of the slider 5 and the electric cylinder 3, which can be designed according to actual conditions. The electric pump 15 can be associated with the slider 5, and when the slider 5 is started, the electric pump 15 starts to pump liquid, so that the fruit trees are sprayed when the slider 5 moves.

[0033] The lower support rod 7 and the middle support rod 8 are both square, and one end of the middle support rod 8 and the upper support rod 9 is welded with a square sleeve 26. The middle support rod 8 and the upper support rod 9 are sleeved through the sleeve 26, and the square structure can be limited when sleeved. The sleeve 26 is threaded with a fixing bolt 27, and the bolt tails of the bolts are respectively abutted against the outer walls of the lower support rod 7 and the middle support rod 8.

[0034] The lower support rod 7 is arranged horizontally, the middle support rod 8 is arranged vertically, and the nozzles 11 thereon spray the sides of the crowns of the fruit trees. The upper support rod 9 is arranged obliquely in the horizontal direction, and the nozzles 11 thereon spray the tops of the crowns.

[0035] The working principle of the present invention is:

[0036] Before use, put the medicine or water fertilizer into the medicine box 13, link the opening and closing of the electric pump 15 with the opening and closing of the slider 5, adjust the positions of the middle support rod 8 and the upper support rod 9 according to the crown height and width of the fruit tree, tighten the fixing bolts 27 after adjustment, and remove the spray pipe 10 in the process, and fix the spray pipe 10 after adjustment. Open the spray head 11 as needed, and close the spray head 11 that does not need to spray medicine, so as to control the spraying amount and spraying range.

[0037] When in use, the height of the lower support rod 7 is adjusted by the control button 19 so that the lower support rod 7 is as close to the bottom of the tree crown as possible. The notch 21 of the positioning plate 2 is stuck on the trunk of the fruit tree by pushing the push handle 18, thereby completing the positioning. The slider 5 is started by the control button 19, and the slider 5 slides along the arc-shaped guide rail 4. At the same time, the electric pump 15 is turned on, and the medicine or water fertilizer is pumped into each nozzle 11 through the hose 28, the rotary joint 12, and the spraying pipe 10 to spray the fruit trees. After the slider 5 slides to the other end of the arc-shaped slide rail and contacts the corresponding proximity switch 24, the rotation action is triggered, and the slider 5 slides back. When it slides to the starting position and contacts the corresponding proximity switch 24, the stop action is triggered, and the electric pump 15 is turned off at the same time, thereby completing the spraying of the fruit trees. When the push handle 18 is pushed to spray the next fruit tree, the trunk height of each fruit tree is different, and the height can be adjusted at any time by the electric cylinder 3. The crown height and width of each fruit tree are also different, but fruit trees need pruning and other operations, and the difference in the crown will not be very large. Therefore, when adjusting the position of the middle support rod 8 and the upper support rod 9, it is appropriate to increase it a little bit, so there is no need to adjust it again.

[0038] When the slider 5 rotates 180 degrees, the spraying pipes 10 on both sides rotate 180 degrees, so that the fruit trees are sprayed 360 degrees. After spraying, the positioning plate 2 can be retracted into the groove 17, and the lower support rod 7, the middle support rod 8, the upper support rod 9, and the spraying pipe 10 can be disassembled, thereby reducing the occupied space and facilitating storage.

[0039] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should all fall within the scope of protection of the present invention.

[0040] The techniques, shapes, and structural parts not described in detail in the present invention are all well-known techniques.
