Description

[0002] During the process of fruit tree planting, timely and appropriate irrigation and fertilization are crucial for the growth of fruit trees and the quality of fruits.

Detailed Embodiment

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0049] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] Refer to Figures 1 - 5 , the present utility model provides a fruit tree spraying device, including:

[0051] A trolley assembly, on which a control system 1 is installed; the control system 1 can be set according to the specific use environment. For example, it can be a single-chip microcomputer or controlled by methods such as PLC, ARM (Advanced RISC Machine), FPGA (Field-Programmable Gate Array), etc. No specific limitation is made in this embodiment;

[0052] A lifting mechanism, which includes a scissor lifting assembly and a platform 2. The platform 2 is installed on the trolley assembly through the scissor lifting assembly;

[0053] A water supply assembly, which is installed on the platform 2;

[0054] A rotating mechanism, which includes a rotating cylinder 3 and a driving assembly. The top of the rotating cylinder 3 is closed, and the bottom is rotatably connected to the platform 2; the driving assembly is installed on the platform 2 and is located in the inner cavity of the rotating cylinder 3. The driving assembly is used to drive the rotating cylinder 3 to rotate;

[0055] A double lead screw assembly, which is installed on the top of the rotating cylinder 3. Two symmetrically arranged sliding sleeves 15 are installed on the double lead screw assembly;

[0056] There are two spraying arms 4, and the two spraying arms 4 are respectively installed on the two sliding sleeves 15. The spraying arms 4 are communicated with the water supply assembly through hoses 16;

[0057] Among them, the scissor lifting assembly, the driving assembly, the double lead screw assembly, and the water supply assembly are all electrically connected to the control system 1; the control system 1, the scissor lifting assembly, the driving assembly, the double lead screw assembly, and the water supply assembly are powered by a storage battery (not shown in the figure);

[0058] With such a setting, the utility model can realize the flexible movement of the spraying device through the trolley assembly, thereby improving the operation efficiency. The height of the spraying arm 4 can be stably and reliably adjusted through the scissor lift assembly, so as to adjust the spraying height to facilitate the irrigation requirements of fruit trees at different heights, and improve the irrigation efficiency and effect.

[0059] The utility model drives the two spraying arms 4 to turn on the horizontal plane through the rotating mechanism, and adjusts the distance between the two spraying arms 4 through the bidirectional lead screw assembly, so as to adjust the spraying direction and spraying range of the spraying arm 4, ensuring that the irrigation water can evenly cover the fruit tree crown, and improving the irrigation accuracy and effect.

[0060] The utility model realizes the intelligent control of the scissor lift assembly, the drive assembly, the bidirectional lead screw assembly and the water supply assembly through the control system 1, which is easy to operate, reduces the manual labor intensity, and can realize automatic irrigation at fixed time, fixed quantity and fixed point, further improving the irrigation efficiency.

[0061] For a further optimized solution, the water supply assembly includes:

[0062] A water tank 5, and the water tank 5 is installed on the platform 2;

[0063] A drain pipe, which is fixedly connected to the bottom of the side wall of the water tank 5 and is communicated with the inner cavity of the water tank 5;

[0064] A water pump 6, the inlet end of the water pump 6 is fixedly connected and communicated with the drain pipe, and the drain end is fixedly connected and communicated with the two hoses 16;

[0065] Wherein, an electromagnetic valve is installed on the drain pipe, and both the water pump 6 and the electromagnetic valve are electrically connected to the control system 1, and the spraying arm 4 is communicated with the water pump 6 through the hose 16;

[0066] With such a setting, when irrigation is required, the control system 1 sends a signal to the electromagnetic valve to open it, allowing the water in the water tank 5 to flow into the inlet end of the water pump 6 through the drain pipe; subsequently, the control system 1 starts the water pump 6, and the water pump 6 pressurizes the water and transports it to the two hoses 16 through the drain end. The hose 16 is connected and communicated with the spray pipe 41 in the spraying arm 4 through the connector 42, so as to transport the pressurized water to the spray pipe 41, and finally spray it out through the nozzle 44 installed on the spray pipe 41 to realize the irrigation of the fruit trees.

[0067] For a further optimized solution, the scissor lift assembly includes:

[0068] Scissor linkages 7, and two scissor linkages 7 are arranged side by side;

[0069] Cross bars 8, and two cross bars 8 are provided. The two cross bars 8 are fixedly connected between the two scissor linkages 7;

[0070] The electric push rod 9 has its two ends respectively hinged to the two cross bars 8;

[0071] Among them, a bottom slide bar is slidably connected to the cart assembly, a top slide bar is slidably connected to the bottom surface of the platform 2, one top end of the scissor link 7 is hinged to the platform 2, and the other top end is rotatably connected to the top slide bar; one bottom end of the scissor link 7 is hinged to the cart assembly, and the other bottom end is rotatably connected to the bottom slide bar; the electric push rod 9 is electrically connected to the control system 1;

[0072] With such a setting, in the initial state, the electric push rod 9 is in a contracted state, and the scissor link 7 is in the lowest position. At this time, the platform 2 and the components installed thereon are also at the lowest height; when it is necessary to adjust the spraying height, the control system 1 sends a signal to the electric push rod 9 to make it extend. As the electric push rod 9 extends, the distance between the two cross bars 8 gradually increases, pushing the scissor link 7 to move, thereby driving the platform 2 and the components thereon to rise; on the contrary, when the electric push rod 9 contracts, the platform 2 and the components thereon descend, realizing the adjustment of the spraying height.

[0073] In a further optimized solution, an internal gear ring 10 is fixedly connected to the inner side wall of the rotating cylinder 3; the driving assembly includes a driving motor 11 electrically connected to the control system 1. The driving motor 11 is installed on the platform 2 and is located in the inner cavity of the rotating cylinder 3. The output shaft of the driving motor 11 is installed with a driving gear 12 through a coupling, and the driving gear 12 meshes and drives with the internal gear ring 10;

[0074] With such a setting, when it is necessary to adjust the spraying direction of the spraying arm 4, the control system 1 starts the driving motor 11. The output shaft of the driving motor 11 drives the driving gear 12 to rotate through the coupling. Since the driving gear 12 meshes and drives with the internal gear ring 10, the internal gear ring 10 and the rotating cylinder 3 fixedly connected thereto will also rotate accordingly. The rotation of the rotating cylinder 3 will drive the bidirectional lead screw assembly and the spraying arm 4 installed on its top to rotate together, thereby realizing the adjustment of the spraying direction.

[0075] In a further optimized solution, the bidirectional lead screw assembly includes:

[0076] A lead screw motor 13, which is installed on the top of the rotating cylinder 3;

[0077] A bidirectional lead screw 14, which is installed on the output shaft of the lead screw motor 13 through a coupling. The two ends of the bidirectional lead screw 14 are installed on the top of the rotating cylinder 3 through bearing seats;

[0078] Among them, the lead screw motor 13 is electrically connected to the control system 1. The two sliding sleeves 15 are symmetrically arranged, and the sliding sleeves 15 are slidably sleeved on the bidirectional lead screw 14;

[0079] With such a setting, when it is necessary to adjust the distance between the two spray arms 4, the control system 1 starts the lead screw motor 13. The output shaft of the lead screw motor 13 drives the bidirectional lead screw 14 to rotate through a coupling. Since the two sliding sleeves 15 are symmetrically sleeved on the bidirectional lead screw 14 and are in threaded cooperation with it, when the bidirectional lead screw 14 rotates, the two sliding sleeves 15 will move relatively or towards each other along the axial direction of the bidirectional lead screw 14. The movement of the sliding sleeve 15 will drive the spray arm 4 fixedly connected to it to move together, thereby adjusting the distance between the two spray arms 4 and realizing the adjustment of the spraying range.

[0080] For a further optimized solution, the spray arm 4 includes:

[0081] A spray pipe 41, with a sealing end cap installed at one end of the spray pipe 41;

[0082] A connecting head 42, which is installed at the end of the spray pipe 41 away from the sealing end cap;

[0083] A support rod 43, which is fixedly connected to the connecting head 42 and is fixedly installed on the sliding sleeve 15;

[0084] Spray nozzles 44, there are several spray nozzles 44, and several spray nozzles 44 are installed on the spray pipe 41, and the spray nozzles 44 are communicated with the spray pipe 41;

[0085] Among them, the flexible hose 16 is communicated with the inner cavity of the spray pipe 41 through the connecting head 42;

[0086] With such a setting, during operation, the pressurized water enters the connecting head 42 through the flexible hose 16 and flows into the inner cavity of the spray pipe 41; subsequently, the water is sprayed out through the spray nozzles 44 installed on the spray pipe 41 to form fine water mist or water flow to cover the fruit tree crown.

[0087] For a further optimized solution, the trolley assembly includes a base 17, several walking wheels are installed at the bottom of the base 17, a push rod 18 is installed on one side of the base 17, the control system 1 is installed on the push rod 18, and the bottom slide rod is slidably connected to the base 17; the operator can conveniently move the base 17 in the orchard through the push rod 18.

[0088] For a further optimized solution, a water filling port and a drain port are installed on the water tank 5, a water level observation window 19 is installed on the side wall of the water tank 5, and scales are provided on the water level observation window 19 to improve the operation convenience.
