Description

Technical Field

[0001] This invention relates to the field of agricultural fertilization technology, and more specifically, to a device for simultaneous fertilization and irrigation of fruit trees in orchards. Background Technology

[0002] In orchard management, fertilization and irrigation are two crucial and closely related operations. The coupling effect of water and fertilizer has a decisive impact on the growth, development, yield, and quality of fruit trees.

[0003] In traditional orchard management, there are two fertilization methods. One is to separate fertilization and irrigation into two independent processes. Fertilizer is first applied manually or using simple equipment by digging trenches, holes, or spreading it around the tree canopy projection, followed by irrigation. This traditional step-by-step method is cumbersome, labor-intensive, and consumes significant manpower and time. Furthermore, if the fertilizer applied to the soil surface or shallow layer does not mix thoroughly with irrigation water in time, it is difficult for the roots to absorb it effectively, resulting in low fertilizer utilization. This not only causes economic waste, but residual fertilizer may also be lost with rainwater or irrigation runoff, potentially causing pollution. The other method involves applying liquid fertilizer. However, existing equipment suffers from uneven application of liquid fertilizer. Additionally, for fruit trees of different diameters and growth stages, existing devices struggle to flexibly adjust the fertilization position and angle, making it difficult to precisely target the root zone and affecting the tree's absorption efficiency. Therefore, we propose a simultaneous fertilization and irrigation device for orchard fruit trees. Summary of the Invention

Furthermore, if the fertilizer applied to the soil surface or shallow layer fails to fully integrate with the irrigation water in time, it is difficult for the roots to effectively absorb it, resulting in low fertilizer utilization. This not only causes economic waste, but the residual fertilizer may also cause pollution due to being washed away by rainwater or irrigation runoff.

The screw is vertically disposed within the U-shaped frame and its two ends are rotatably connected to the U-shaped frame. The second motor is disposed at the top of the U-shaped frame and its output end is rotatably connected to the top of the screw. The nut seat is threadedly connected to the screw and fixedly connected to the U-shaped frame.

[0008] As a further improvement of the present invention, a guide hole is provided on the C-shaped frame along the vertical direction, and a guide rod is fixedly connected to the nut seat, the guide rod being slidably connected to the guide hole.

[0009] As a further improvement of the present invention, the plurality of discharge pipes are distributed at equal angular intervals on the corresponding arc-shaped seats.

[0010] As a further improvement of the present invention, the power assembly includes: an air pump, a multi-port pipe, an arc frame, multiple fixed pipes, and multiple air inlet pipes. The air pump and the multi-port pipe are respectively disposed on the trolley and the C-shaped seat. The arc frame is concentrically disposed with the corresponding arc frame, and the arc frame is fixedly connected to the arc frame. The multiple fixed pipes are all fixedly connected to the inner side of the arc frame, and their axes are arranged radially along the arc frame. The multiple fixed pipes correspond one-to-one with the multiple drive rods. One end of the drive rod is slidably connected to the fixed pipe, and the other end is connected to the discharge pipe. The multiple air inlet pipes correspond one-to-one with the multiple fixed pipes, and one end of the air inlet pipe communicates with the interior of the fixed pipe. The multi-port pipe is simultaneously connected to the other end of the air pump and the air inlet pipe.

[0016] 1. This invention, by setting up a trolley, a drive assembly, and two surrounding fertilization assemblies, supports the drive assembly and surrounding fertilization assemblies, facilitating mobile fertilization and making it more convenient to use. In addition, the drive assembly moves the two surrounding fertilization assemblies closer together or apart to wrap around and open the main trunk of the fruit tree. In the wrapped state, the liquid fertilizer in the fertilizer tank is transported into the cavity through the inlet pipe by the liquid pump, and then poured around the main trunk of the fruit tree through multiple outlet pipes. This can realize the surrounding application of liquid fertilizer to the main trunk of the fruit tree, improving the accuracy and uniformity of fertilization.

In this invention, the angle adjustment component, through the power component and multiple drive rods, can simultaneously adjust the discharge ports of multiple discharge pipes to move toward the center of the arc-shaped seat, thereby flexibly adjusting the fertilization angle. It is suitable for fruit tree trunks of various diameters, which can further improve the accuracy of fertilization and also enhance the applicability of the device. Attached Figure Description

Detailed Implementation

[0032] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0033] like Figures 1-13 As shown, a synchronous fertilization and irrigation device for orchard fruit trees includes a cart 1 and a fertilization mechanism 2. The cart 1 mainly serves as a support and transport mechanism. The fertilization mechanism 2 is connected to the cart 1, so that the cart 1 can drive the fertilization mechanism 2 to move, thereby facilitating the fertilization and irrigation of the fruit trees.

[0034] In addition, such as Figure 2 As shown, the fertilization mechanism 2 includes a drive assembly 21 and two surrounding fertilization assemblies 22. The drive assembly 21 is connected to both surrounding fertilization assemblies 22 and is used to drive the two surrounding fertilization assemblies 22 to selectively wrap around the trunk of the fruit tree. This design can accommodate fruit tree trunks of various diameters, improving the versatility and adaptability of the device.

[0035] Specifically, such as Figure 2 , Figure 6 , Figure 9 and Figure 13 As shown, each surrounding fertilization assembly 22 includes an arc-shaped seat 221 and an angle adjustment assembly 222. The arc-shaped seat 221 has an internal cavity 2211. An inlet pipe 2212 communicating with the cavity 2211 is located at the top of the arc-shaped seat 221, and multiple flexible outlet pipes 2213 communicating with the cavity 2211 are located at the bottom of the arc-shaped seat 221. The inlet pipe 2212 receives a mixture of fertilizer and water, i.e., liquid fertilizer, and distributes the liquid fertilizer into the multiple outlet pipes 2213 through the cavity 2211, thereby applying the liquid fertilizer around the main trunk of the fruit tree. The design of the flexible outlet pipes 2213 allows them to be flexible when adjusting the angle, making them less prone to damage and better adaptable to angle changes.

[0036] In addition, such as Figure 2 , Figure 10 and Figure 11 As shown, the angle adjustment component 222 is used to simultaneously adjust the fertilization angle of multiple discharge pipes 2213. The angle adjustment component 222 includes a power component 2222 and multiple drive rods 2221. Each drive rod 2221 corresponds to one of the multiple discharge pipes 2213. The power component 2222 is mounted on the arc-shaped seat 221 and selectively drives the discharge ports of multiple discharge pipes 2213 to move towards the center of the arc-shaped seat 221. By adjusting the direction of the discharge ports of the discharge pipes 2213, the range and angle of liquid fertilizer application can be changed, thereby allowing for more precise application of liquid fertilizer to the root zone of fruit trees.

[0037] For example, when the diameter of the main trunk of the fruit tree is smaller than the diameter of the arc-shaped seat 221, the power assembly 2222 can drive multiple drive rods 2221 to move towards the center of the arc-shaped seat 221. This causes the outlet of the corresponding discharge pipe 2213 to tilt towards the center of the arc-shaped seat 221, allowing the applied liquid fertilizer to be closer to the roots of the fruit tree, which is beneficial for the tree's absorption. When the diameter of the main trunk of the fruit tree is similar to the diameter of the arc-shaped seat 221, there is no need to adjust the position of the discharge pipe 2213. Of course, adjustments can be made flexibly according to actual working conditions.

[0038] As an optional embodiment, such as Figure 10 As shown, multiple discharge pipes 2213 are distributed at equal angular intervals on the corresponding arc-shaped seats 221. This design of equal angular intervals allows the liquid fertilizer to be distributed more evenly around the fruit tree roots, thereby improving the uniformity and accuracy of liquid fertilizer application. Of course, a solenoid valve can also be installed at each discharge pipe 2213 for more precise control of the liquid fertilizer flow.

[0039] In addition, such as Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the trolley 1 is equipped with a connecting assembly 11, which mainly serves a connecting function. The drive assembly 21 includes a motor 211, a C-shaped base 212, a first rotating shaft 213, a second rotating shaft 214, a third rotating shaft 215, a first gear 216, a second gear 217, and a third gear 218. The C-shaped base 212 is mounted on the connecting assembly 11, with its opening facing away from the trolley 1. The two parallel portions of the C-shaped base 212 are positioned vertically. The first rotating shaft 213, the second rotating shaft 214, and the third rotating shaft 215 are all rotatably connected within the C-shaped base 212, and their axes are all vertically aligned and parallel to each other. Gear 1 216, gear 2 217, and gear 3 218 are fixedly connected to shaft 1 213, shaft 2 214, and shaft 3 215, respectively, with gear 1 216 meshing with gear 2 217 and gear 2 218 meshing. Motor 1 211 is fixedly connected to the top of the U-shaped seat 212, and the output end of motor 1 211 is fixedly connected to shaft 3 215. One end of each of the two arc-shaped seats 221 is fixedly connected to shaft 1 213 and shaft 2 214, respectively.

[0040] In initial use, the other ends of the two arc-shaped seats 221 are separated. When the trolley 1 moves the main trunk of the fruit tree into the two arc-shaped seats 221, motor 1 211 is activated. Motor 1 211 drives shaft 3 215 to rotate. The rotation of shaft 3 215, through the engagement of gears 3 218, 2 217, and 1 216, drives shafts 1 213 and 2 214 to rotate synchronously, with shafts 1 213 and 2 214 rotating in opposite directions. This allows the other ends of the two arc-shaped seats 221 to move closer together, effectively wrapping the main trunk of the fruit tree. This facilitates more precise application of liquid fertilizer around the roots of the main trunk. After fertilization, reversing motor 1 211 separates the other ends of the two arc-shaped seats 221, opening the main trunk of the fruit tree.

[0041] In addition, such as Figure 3As shown, the fertilization mechanism 2 also includes a height adjustment component 223, which is used to adjust the height of the two components surrounding the fertilization assembly 22. The height adjustment component 223 includes a U-shaped frame 2231, a connecting plate 2232, a screw 2233, a nut seat 2234, and a second motor 2235. The opening of the U-shaped frame 2231 faces away from the trolley 1, and the two parallel portions of the U-shaped frame 2231 are arranged vertically. The connecting plate 2232 is fixedly connected to both the connecting assembly 11 and the U-shaped frame 2231. The screw 2233 is vertically arranged inside the U-shaped frame 2231, and both its upper and lower ends are rotatably connected to the U-shaped frame 2231. The second motor 2235 is fixedly connected to the top of the U-shaped frame 2231, and the output end of the second motor 2235 is rotatably connected to the top end of the screw 2233. Nut seat 2234 is threadedly connected to screw 2233, and nut seat 2234 is fixedly connected to C-shaped seat 212.

[0042] When adjusting the fertilization height during use, motor 2235 is started. Motor 2235 drives screw 2233 to rotate. The rotation of screw 2233 causes nut seat 2234 to move up and down along the axis of screw 2233. This causes the C-shaped seat 212, the drive component 21 on it, and the two surrounding fertilization components 22 to move up and down as a whole, thereby adjusting the height of the surrounding fertilization components 22 to adapt to different terrain heights, making it more flexible and applicable.

[0043] As an optional embodiment, such as Figure 8 As shown, a guide hole 22311 is provided on the C-shaped frame 2231 along the vertical direction. A guide rod 22331 is fixedly connected to the nut seat 2234, and the guide rod 22331 is slidably connected to the guide hole 22311. The cooperation between the guide rod 22331 and the guide hole 22311 can prevent the nut seat 2234 from rotating when moving up and down, thereby improving the stability of height adjustment.

[0044] In addition, such as Figure 3 , Figure 4 , Figures 9-11 As shown in Figure 13, the power assembly 2222 includes an air pump 22221, a multi-port pipe 22222, an arc-shaped frame 22223, multiple fixed pipes 22224, and multiple air inlet pipes 22225. The air pump 22221 and the multi-port pipe 22222 are respectively fixedly mounted on the trolley 1 and the C-shaped seat 212. The arc-shaped frame 22223 is concentrically arranged with the corresponding arc-shaped seat 221, and the arc-shaped frame 22223 is fixedly connected to the arc-shaped seat 221. It should be noted that the cross-sectional shape of the arc-shaped frame 22223 in the radial direction can be an inverted L-shape, and the top of the arc-shaped frame 22223, i.e., the horizontal part, is fixedly connected to the top of the corresponding arc-shaped seat 221.

[0045] Multiple fixed tubes 22224 are fixedly connected to the inner side of the arc-shaped frame 22223, that is, to the inner wall of the vertical part of the arc-shaped frame 22223, and the axes of the multiple fixed tubes 22224 are all arranged radially along the arc-shaped frame 22223. Each fixed tube 22224 corresponds to one of the multiple drive rods 2221. One end of the drive rod 2221 is slidably connected to the fixed tube 22224, and the other end can be fixedly connected to the discharge pipe 2213. Multiple air inlet pipes 22225 correspond to each of the multiple fixed tubes 22224, and one end of the air inlet pipe 22225 communicates with the interior of the fixed tube 22224. A multi-port pipe 22222 is simultaneously connected to the air pump 22221 and the other end of the air inlet pipe 22225.

[0046] It should be noted that the multi-port pipe 22222 has one inlet and multiple outlets. The inlet can be connected to the air pump 22221 through a hose, and the multiple outlets can be connected to the other end of multiple air inlet pipes 22225 through multiple hoses.

[0047] When it is necessary to adjust the angle of the discharge port of the discharge pipe 2213, the air pump 22221 is started. The air pump 22221 will fill the multi-port pipe 22222 with air through the inlet. The gas in the multi-port pipe 22222 will be distributed to multiple air inlet pipes 22225 through multiple outlets, and then enter the fixed pipe 22224. Under the action of air pressure, the drive rod 2221 will move towards the center of the arc-shaped seat 221, thereby realizing the adjustment of the discharge port angle of the discharge pipe 2213.

[0048] It should be noted that, since the distances between the multiple outlets of the multi-port pipe 22222 and the corresponding multiple air inlet pipes 22225 are different, to ensure that the gas entering each air inlet pipe 22225 is more synchronized and uniform, flexible hoses of different lengths can be used to connect the outlets to the corresponding air inlet pipes 22225. This ensures that the paths between the multiple outlets and the corresponding multiple air inlet pipes 22225 are approximately the same, thereby making the gas entering each air inlet pipe 22225 more synchronized and uniform. This facilitates the synchronous adjustment of the angles of the multiple discharge pipes 2213. After adjustment, the air pump 22221 is stopped, maintaining the tilted state of the discharge pipe 2213. After fertilization is completed, the air pump 22221 is started to extract the air from the fixed pipe 22224, facilitating the next adjustment of the tilt angle of the discharge pipe 2213.

[0049] As an optional embodiment, such as Figure 11As shown, a spring 22226 is installed inside the fixed tube 22224. The two ends of the spring 22226 can be fixedly connected to the bottom wall of the fixed tube 22224 and one end of the drive rod 2221, respectively. The spring 22226 mainly provides a restoring force. When the air pump 22221 extracts air, the spring 22226 can be used to return the drive rod 2221 to its original position. Additionally, the spring 22226 can be used to limit the movement of the drive rod 2221, facilitating repeated driving of the drive rod 2221.

[0050] Furthermore, as shown in the figure, a collar 22211 is fixedly connected to the other end of the drive rod 2221. The collar 22211 is vertically slidably connected to the corresponding discharge pipe 2213. The collar 22211 facilitates the engagement of the drive rod 2221 with the discharge pipe 2213, making loading and unloading convenient.

[0051] In addition, such as Figure 12 As shown, the connecting assembly 11 includes a hollow connecting base 111, a motor 112, and a turntable 113. The connecting base 111 is fixedly connected to the trolley 1. The turntable 113 is rotatably connected to the top of the connecting base 111. The motor 112 is fixedly connected inside the connecting base 111, and the output end of the motor 112 is fixedly connected to the center of the turntable 113. The connecting plate 2232 is fixedly connected to the turntable 113.

[0052] When in use, start motor 3112, which can drive turntable 113 to rotate, thereby driving connecting plate 2232 and fertilizer mechanism 2 on it to rotate horizontally as a whole, thereby adjusting the working direction of fertilizer mechanism 2 and improving the flexibility and working range of the device.

[0053] In addition, such as Figure 1 and Figure 2 As shown, the fertilization mechanism 2 also includes a fertilizer tank 23 and two liquid pumps 24. The fertilizer tank 23 can be placed or fixedly connected to the trolley 1, and the two liquid pumps 24 can be fixedly connected to the trolley 1. The inlets of the two liquid pumps 24 are connected to the inside of the fertilizer tank 23, and the outlets of the two liquid pumps 24 are respectively connected to two feed pipes 2212. The fertilizer tank 23 is used to store liquid fertilizer, and the liquid pumps 24 are used to transport the liquid fertilizer from the fertilizer tank 23 to the corresponding feed pipes 2212 surrounding the fertilization assembly 22, and then fertilize the fruit trees through the cavity 2211 and multiple discharge pipes 2213, thereby improving the continuity and stability of the fertilization process.

[0054] It should be noted that the wheels of the trolley 1 can be swivel casters, making it easy to adjust the direction of the trolley 1. In addition, a battery is installed at the rear of the trolley 1 to power the electrical components.

[0055] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
