Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation and fertilization equipment technology, specifically to a truss-mounted multi-compartment time-sharing integrated water and fertilizer assembly device. Background Technology

[0002] In large-scale field planting, the horizontal truss sprinkler irrigation machine is a commonly used irrigation equipment. To achieve integrated water and fertilizer management, existing technologies typically install a large fertilizer mixing tank at the head of the sprinkler irrigation machine or a fixed position in the field. Macronutrient fertilizers, micronutrient fertilizers, and other fertilizers are pre-mixed with water to prepare a single-formula fertilizer solution, which is then sucked into the main irrigation pipeline via a Venturi injector or metering pump and applied to the field along with the irrigation water. Some improved solutions involve adding a single fertilizer solution tank to the sprinkler irrigation machine, allowing operators to dispense the pre-mixed fertilizer solution as needed, or installing multiple fertilizer suction channels in the pipeline to draw different fertilizers from multiple fixed mother liquor tanks.

[0003] However, in practical applications, the aforementioned existing technologies struggle to automatically switch between multiple liquid fertilizer formulations without interrupting operations during continuous truss movement, based on the nutritional needs of different planting zones or crop growth stages. Operators often need to stop the machine, drain excess liquid, clean pipelines, and then refill or connect another fertilizer formulation. This process is not only labor-intensive and inefficient, but also prone to application delays and dosage deviations due to reliance on manual experience for formula switching. Consequently, fertilization accuracy is low, fertilizer waste is significant, and even crop quality and yield may be affected by nutrient mismatch. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-compartment time-sharing fertigation assembly device for the entire truss machine, so as to solve the technical problem in the prior art that the translational truss sprinkler irrigation machine cannot automatically switch between multiple fertilizer liquid formulas in different times and areas when applying fertilizer.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a truss-mounted multi-compartment time-sharing integrated water and fertilizer assembly device, comprising a translational truss main beam frame, and further comprising:

[0006] The snap-fit ​​connector is detachably installed on the main beam frame of the translation truss.

[0007] A support plate is fixedly installed on the top of the snap-fit ​​component;

[0008] Linkage plate groups are arranged at intervals along the length of the support plate, and one linkage plate group consists of two linkage plates;

[0009] Multiple independent, sealed fertilizer storage bins are located below the main beam of the translation truss, and each fertilizer storage bin is mounted on one of the linkage plate groups;

[0010] The liquid outlet pipe is installed on the bottom outer wall of each fertilizer storage bin, and its inlet end is connected to the pump body installed inside the fertilizer storage bin.

[0011] An electrically controlled switching valve is installed on each of the aforementioned outlet pipes;

[0012] A mixing main pipe, one end of which is connected to the outlet of each of the aforementioned liquid outlet pipes, is used to collect the liquids from each liquid outlet pipe together.

[0013] A mixing and conveying mechanism, installed at the top of the bearing plate, is used to convey the mixed fertilizer solution in the mixing main pipe to the spraying pipe installed on the main beam of the translation truss.

[0014] The controller is electrically connected to each of the electronically controlled switching valves and stores multiple fertilizer formulas. The controller can switch the on and off of the electronically controlled switching valves so that the fertilizer liquid flowing out from different fertilizer storage tanks is combined and flows into the mixing main pipe according to the formula.

[0015] A lifting and mounting assembly is installed between the bearing plate and the linkage plate group to adjust the height of each of the fertilizer storage bins.

[0016] Furthermore, the snap-fit ​​components are spaced apart on the main beam of the translation truss and located above each of the fertilizer storage bins; each snap-fit ​​component consists of a first snap ring, a second snap ring, and a locking component. The first snap ring and the second snap ring are fitted together and snapped onto the main beam of the translation truss, and the locking component locks the first snap ring and the second snap ring. The inner walls of the first snap ring and the second snap ring are also provided with an anti-slip layer that fits against the outer wall of the main beam of the translation truss.

[0017] Furthermore, the bearing plate is in the shape of an "H" shaped plate and is a component made of steel, which is fixedly installed on the top of the first retaining ring, and the linkage plate assembly is vertically arranged on both sides of the bearing plate.

[0018] Furthermore, each of the fertilizer storage bins is provided with a fertilizer inlet at the top, and each of the liquid outlet pipes is also provided with an electrically controlled throttle valve connected in parallel with the electrically controlled switch valve. The diameter of the mixing main pipe is larger than the diameter of each of the liquid outlet pipes.

[0019] Furthermore, the mixing and conveying mechanism consists of a mixing cylinder, a conveying pump body, and a conveying pipe. The conveying pump body is installed at the bottom of the mixing cylinder. The other end of the mixing main pipe is connected to the inlet of the conveying pump body. One end of the conveying pipe is connected to the outlet of the conveying pump body, and the other end is connected to each of the spraying pipelines.

[0020] Furthermore, a first driving component with an external power supply is installed on the top of the mixing cylinder. A vertical power shaft is provided inside the mixing cylinder. The top of the power shaft is connected to the output shaft of the first driving component through a coupling. A multi-layered positioning plate is fixedly installed on the power shaft. A stirring plate is distributed circumferentially on the outer wall of the positioning plate. The stirring plate is an inclined plate.

[0021] Furthermore, the lifting and mounting assembly consists of a guide rack, a drive gear, a second drive component, a mounting plate, and a retaining ring. The guide rack is vertically and fixedly installed on the inner side wall of each of the linkage plates. Positioning plates are symmetrically distributed at intervals on the left and right outer side walls of the bearing plate. A drive shaft is fixed on the drive gear, and both ends of the drive shaft are rotatably connected to the positioning plates. The second drive component is installed on the outer side wall of the positioning plate, and its output shaft is connected to the drive shaft through a coupling.

[0022] Furthermore, the mounting plate is fixedly connected to the bottom of each of the linkage plates. The vertical cross-section of the mounting plate is L-shaped, and the end of the horizontal section of the L-shape is fixedly connected to the linkage plate. The retaining ring is welded to the outer wall of each fertilizer storage bin. The retaining ring has symmetrical vertical positioning grooves. The retaining ring passes downward through the positioning grooves on it through the L-shaped vertical section of the mounting plate, thereby mounting the fertilizer storage bin between the two linkage plates.

[0023] Furthermore, limiting plates are fixedly installed on the left and right side walls of the bearing plate. The limiting plates are spaced apart along the length of the bearing plate. Each side of the linkage plate has a limiting plate. Limiting grooves are opened on the two opposing limiting plates, and the linkage plate is movably locked in the corresponding limiting groove.

[0024] Compared with existing technologies, this invention provides a multi-compartment time-sharing fertigation assembly for a truss-type sprinkler system. Multiple independent, sealed fertilizer storage compartments are integrally mounted on the main beam of the sliding truss via snap-fit ​​connectors. Each fertilizer compartment's outlet pipe is equipped with an electrically controlled valve connected to a controller, which stores fertilizer formulas corresponding to different planting areas. During truss operation, the controller switches the on / off states of each valve according to the formula diagram, allowing fertilizer solutions from different compartments to flow into the mixing main pipe according to a preset combination and be instantly mixed and delivered to the spraying pipeline. This achieves automatic formula switching and online fertilizer mixing for different planting areas within the same operating stroke, solving the problem that sliding truss sprinkler machines cannot automatically switch between multiple fertilizer formulas at different times and in different areas. It also avoids the operational interruptions and application delays caused by manual re-mixing of fertilizer solutions required in traditional methods. Furthermore, the lifting and mounting assembly between the support plate and the linkage plate group can adjust the height of the fertilizer storage compartments, lowering them to a convenient operating height when replenishment or maintenance is needed, further improving the ease of use of the equipment.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] As attached Figure 1 To be continued Figure 6 As shown:

[0036] Example 1:

[0037] This invention provides a truss-type sprinkler irrigation machine equipped with a multi-compartment time-sharing fertigation assembly, which is used to automatically switch the fertilization formula for different planting areas during continuous operation.

[0038] The main body of the device is mounted on the main beam frame 1 of the translation truss. For easy installation and disassembly, the device is detachably connected to the main beam frame 1 of the translation truss via snap-fit ​​connectors 2.

[0039] like Figure 2 As shown, the snap-fit ​​components 2 are arranged at intervals along the extension direction of the main beam frame 1 of the translation truss and are located above each fertilizer storage bin 5. The snap-fit ​​component 2 consists of a first snap ring 201, a second snap ring 202, and a locking component 203. The first snap ring 201 and the second snap ring 202 are semi-circular or arc-shaped. After they are engaged, they are snapped onto the members of the main beam frame 1 of the translation truss, and then locked by the locking component 203. To enhance the stability of the connection and prevent the snap-fit ​​component 2 from slipping during the vibration of the truss, an anti-slip layer 10 is also provided on the inner wall of the first snap ring 201 and the second snap ring 202. This anti-slip layer 10 is in close contact with the outer wall of the main beam frame 1 of the translation truss, increasing the friction and improving the stability and reliability of the load.

[0040] A support plate 3 is fixedly installed on the top of the snap-fit ​​component 2. The support plate 3 is a long strip structure extending along the truss direction, serving as the mounting base for all components of the entire device. On both sides of the support plate 3, multiple sets of linkage plate groups are spaced apart along its length, each linkage plate group consisting of two opposing linkage plates 4. Each linkage plate group is equipped with an independent sealed fertilizer storage bin 5, so that the multiple fertilizer storage bins 5 are located directly below the main beam frame 1 of the translation truss. This layout makes full use of the space under the truss and makes the center of gravity of the device closer to the center line of the truss. Each fertilizer storage bin 5 is equipped with a fertilizer inlet 11 on its top for adding different types of liquid fertilizers, such as macro-element fertilizer solution, micro-element fertilizer solution, or functional liquid fertilizer solution.

[0041] like Figure 3 As shown, each fertilizer storage bin 5 has an outlet pipe 6 connected to its bottom outer wall. The inlet end of the outlet pipe 6 is connected to a pump body installed inside the fertilizer storage bin 5. The pump body actively draws fertilizer solution from the fertilizer storage bin 5, ensuring the continuity and stability of fertilizer solution delivery. Each outlet pipe 6 is equipped with an electrically controlled switch valve 7 to control the on / off state of the fertilizer solution in that path. As a further optimization, each outlet pipe 6 is also equipped with an electrically controlled throttle valve 12 connected in parallel with the electrically controlled switch valve 7. The electrically controlled throttle valve 12 can regulate the flow rate of fertilizer solution through the pipeline. Working in conjunction with the electrically controlled switch valve 7, it can dynamically adjust the flow rate of fertilizer solution while simultaneously opening and closing the channel, improving the accuracy of the mixed fertilizer ratio.

[0042] The outlets of each liquid outlet pipe 6 eventually converge into a mixing main pipe 8. The diameter of the mixing main pipe 8 is larger than that of a single liquid outlet pipe 6. This provides sufficient flow space for multiple liquid streams to flow in simultaneously, avoids excessive pressure in the pipeline, and allows the multiple liquid streams to undergo initial turbulent mixing after merging.

[0043] like Figure 4 As shown, the other end of the mixing main pipe 8 is connected to the mixing and conveying mechanism. The mixing and conveying mechanism mainly consists of a mixing cylinder 13, a conveying pump 14, and a conveying pipe 15. The mixing cylinder 13 is installed at the top of the support plate 3, and the conveying pump 14 is located at the bottom of the mixing cylinder 13. The end of the mixing main pipe 8 is connected to the inlet of the conveying pump 14, and the outlet of the conveying pump 14 is connected to one end of the conveying pipe 15. The other end of the conveying pipe 15 is connected to the existing spraying pipe 9 on the main beam frame 1 of the translation truss. During operation, the fertilizer solutions from each path converge in the mixing main pipe 8, are drawn into the conveying pump 14, and are delivered into the spraying pipe 9 under conveying pressure, and finally applied to the field through the nozzles.

[0044] To achieve more thorough mixing, a first drive unit 16 with an external power supply is installed on the top of the mixing cylinder 13. The first drive unit 16 can be a motor. A power shaft 17 is vertically arranged inside the mixing cylinder 13, and the top of the power shaft 17 is connected to the output shaft of the first drive unit 16 via a coupling. On the power shaft 17, multiple positioning discs 18 are fixedly installed axially. Each positioning disc 18 has multiple agitator plates 19 circumferentially distributed on its outer wall. The agitator plates 19 are plates that are inclined relative to the horizontal plane. When the first drive unit 16 drives the power shaft 17 to rotate, the multiple agitator plates 19 stir the fertilizer solution at different heights inside the mixing cylinder 13, so that the multiple streams of fertilizer solution that have just merged are fully dispersed and mixed evenly in a short time, and then pressurized and sent out by the delivery pump 14.

[0045] The automatic control of the device is achieved by a controller, which is installed in the electrical control box of the translation truss or integrated on the bearing plate 3. The controller is electrically connected to each electrically controlled switch valve 7, electrically controlled throttle valve 12 and the first drive component 16. Its internal memory contains multiple fertilizer formulas, each formula corresponding to the type of fertilizer solution and its flow rate ratio that should be activated when the truss moves to a specific position interval.

[0046] During the truss travel operation, the controller switches the corresponding electrically controlled valves 7 on and off according to the acquired travel position information, so that the fertilizer solutions in different fertilizer storage bins 5 are collected into the mixing main pipe 8 in a preset combination at regular intervals. After mechanical stirring in the mixing cylinder 13 and conveying by the conveying pump 14, the fertilizer solution is finally output into the spraying pipeline 9. Thus, this device realizes the function of automatically switching between multiple fertilizer solution formulas as the truss travels without interrupting the irrigation operation, solving the problems of traditional horizontal truss sprinkler irrigation machines that require stopping the machine for manual remixing of fertilizer solutions and cannot accurately supply fertilizer in different zones and at different times.

[0047] Example 2:

[0048] Based on Embodiment 1, this embodiment further optimizes the ease of maintenance and lifting operation of the device.

[0049] like Figure 5 As shown, a lifting and mounting assembly is provided between the bearing plate 3 and the linkage plate group to adjust the height of each fertilizer storage bin 5. The lifting and mounting assembly is composed of a guide rack 20, a drive gear 21, a second drive component 22, a mounting plate 23, and a retaining ring 24.

[0050] In terms of specific configuration, a guide rack 20 is vertically fixedly installed on the inner side wall of each linkage plate 4 (i.e., the side facing each other of two linkage plates 4). On the left and right outer side walls of the bearing plate 3, a set of outwardly extending positioning plates 25 are symmetrically arranged corresponding to the position of each linkage plate group.

[0051] Between each set of positioning plates 25, a drive gear 21 is provided, and a drive shaft 26 is fixedly mounted on the drive gear 21. The two ends of the drive shaft 26 are rotatably connected to the two positioning plates 25 through bearings. The teeth of the drive gear 21 mesh with the guide rack 20 on the linkage plate 4. A second drive component 22 is installed on the outer wall of one of the positioning plates 25. The second drive component 22 can be a motor, and its output shaft is connected to the drive shaft 26 through a coupling.

[0052] like Figure 5 and Figure 6 As shown, the mounting structure of the fertilizer storage bin 5 is as follows: a mounting plate 23 is fixedly connected to the bottom of each linkage plate 4. The vertical cross-section of the mounting plate 23 is L-shaped, with the horizontal end of the L-shape fixedly connected to the bottom end of the linkage plate 4, and the vertical section of the L-shape extending upwards. A retaining ring 24 is welded to the outer wall of each fertilizer storage bin 5, and two vertical positioning slots 27 are symmetrically provided on the retaining ring 24. During installation, the positioning slots 27 on the retaining ring 24 pass downwards through the L-shaped vertical section of the mounting plate 23, so that the fertilizer storage bin 5 is securely mounted on the mounting plate 23 between the two linkage plates through the retaining ring 24.

[0053] When fertilizer replenishment or bottom maintenance is required, the operator activates the second drive unit 22. The drive shaft 26 drives the drive gear 21 to rotate. Since the drive gear 21 meshes with the guide rack 20, and the axial position of the drive gear 21 is constrained by the positioning plate 25, the guide rack 20, along with the entire linkage plate 4 and the mounting plate 23, moves downward in a straight line, smoothly lowering the fertilizer storage bin 5 to near the ground, making it convenient for personnel to stand on the ground for refilling and maintenance operations. Before operation, the second drive unit 22 is reversed to raise the fertilizer storage bin 5 to a high position and hold it there. This lifting method does not require the assistance of hoisting equipment, reducing the difficulty and labor intensity of daily maintenance, and also improving the safety of fertilizer replenishment operations.

[0054] like Figure 6 As shown, to ensure the verticality and smooth movement of the linkage plate 4 during lifting, limit plates 28 are fixedly installed on the left and right side walls of the support plate 3. The limit plates 28 are spaced apart along the length of the support plate 3, with one limit plate 28 on each of the left and right sides of each linkage plate 4. Each of the two opposing limit plates 28 has a vertical limit groove 29. The side of the linkage plate 4 is movably engaged in the corresponding limit groove 29, allowing the linkage plate 4 to slide only up and down along the direction of the limit groove 29, preventing it from shifting forward or backward or deflecting, thus ensuring smooth lifting and accurate positioning after loading.

[0055] The other structures and control methods in this embodiment are the same as in Embodiment 1, and will not be described again here.

[0056] In summary, this device integrates multi-compartment storage, walking-triggered formula switching, online mixing, and liftable maintenance onto a sliding truss, enabling flexible and precise fertilization in different areas. It eliminates the need for separate fertilizer mixing tanks in the field, solves the technical problem of existing technologies that cannot automatically switch fertilizer formulas by time and area, improves the accuracy of fertilization operations, and reduces fertilizer waste and the labor intensity of manual preparation.

[0057] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
