Description

Technical Field

[0001] This invention relates to the field of mechanized agricultural technology, and in particular to an integrated water and fertilizer machine that combines irrigation and fertilization. Background Technology

[0002] The fertigation machine is a modern agricultural intelligent equipment that deeply integrates irrigation and fertilization. Through components such as a control system, fertilizer pump, fertilizer mixing tank, and sensors, it automatically mixes soluble fertilizers according to crop needs and precisely injects them into the irrigation network. It uses drip irrigation or sprinkler irrigation to simultaneously deliver fertilizer and water to the crop root zone, achieving timed, quantitative, and precise supply of water and fertilizer, thereby significantly improving water and fertilizer utilization. It has significant advantages such as saving labor, water, and fertilizer, increasing yield, and reducing environmental pollution, and is widely used in greenhouses, orchards, and open fields.

[0003] Currently, the following problems still exist when using integrated water and fertilizer machines for combined irrigation and fertilization of plants: existing equipment can usually only complete irrigation or fertilization independently, so multiple devices need to be repeatedly brought into the field for management, resulting in a cumbersome operation process. Moreover, most integrated water and fertilizer machines apply water and fertilizer to the surface or shallow layer of soil, resulting in low water and fertilizer utilization rate, which can easily lead to surface runoff and environmental pollution. Furthermore, most existing equipment uses fixed-spacing operation units, which are difficult to adapt quickly to crops with different row or plant spacings. When multiple rows are operated in parallel, there is a lack of effective modular sliding adjustment means, which limits applicability. Summary of the Invention

[0004] In view of the problems that still exist in the above-mentioned or existing technologies when using integrated water and fertilizer machines to irrigate and fertilize plants, such as inaccurate water and fertilizer application location and poor adaptability to the soil in the root zone of the plants, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides an integrated water and fertilizer machine for combined irrigation and fertilization, which is achieved by the following specific technical means: A water and fertilizer integrated machine for coordinated irrigation and fertilization includes a mobile frame and a material carrier fixed thereon, wherein a number of mobile modules are slidably mounted on the mobile frame in a linear array. An irrigation and fertilization mechanism is located at the lower end of the mobile module. The irrigation and fertilization mechanism includes a lifting component located at the lower end of the mobile module. An expansion component is located at the lower end of the lifting component. Several force-bearing rods are arranged in a circular array on the expansion component. An arc-shaped shovel is fixedly installed at the lower end of the force-bearing rods. A fertilizer bin and an irrigation pipe are arranged on the arc-shaped shovel. The lifting component inserts the arc-shaped shovel into the soil around the plant, the expansion component expands the arc-shaped shovel outward to cultivate the soil, the fertilizer bin and irrigation pipe apply fertilizer and water directly to the plant roots, and the expansion component retracts the arc-shaped shovel inward to transplant the plant.

[0006] Preferably, the mobile frame includes two symmetrical triangular frames, with several positioning rods fixedly installed between the triangular frames, and the mobile module is slidably installed on the several positioning rods. Tires distributed front and rear are rotatably installed at the lower end of the triangular frames.

[0007] Preferably, a tractor is fixedly installed at the front end of the material carrier, and a fertilizer storage tank and a water storage tank are fixedly installed on the upper surface of the material carrier.

[0008] Preferably, the moving module is provided with a driving component, which includes a first motor fixedly installed on the moving module, one of the positioning rods having a guide groove, the guide groove being connected to the first motor through a rack and pinion transmission structure, the other positioning rods having limit grooves, and the moving module having balls that are tactilely connected to the limit grooves.

[0009] Preferably, the moving module is further provided with a locking component, which includes a central shaft that is rotatably mounted on the moving module, a locking disc that is fixedly sleeved on the central shaft, a semi-circular pressure block that corresponds one-to-one with the positioning rod being fixedly installed on the locking disc, a second motor being fixedly installed inside the moving module, and the second motor being connected to the central shaft through a gear transmission structure.

[0010] Preferably, the lifting assembly includes a support frame fixedly installed on the mobile module, a hydraulic cylinder fixedly installed inside the support frame, and a fixed plate fixedly installed at the telescopic end of the hydraulic cylinder.

[0011] Preferably, the expansion assembly includes a device frame fixedly installed at the lower end of the fixed plate. Several hinge rods are hinged in a circumferential array at the lower end of the device frame. A special-shaped frame is hinged to the end of the hinge rod away from the corresponding device frame. A third motor is fixedly installed inside the device frame. A screw is fixedly sleeved at the output end of the third motor. An expansion block is threaded onto the screw. The expansion block and the end of the hinge rod away from the corresponding device frame are hinged together to a push rod.

[0012] Preferably, an insertion cylinder is fixedly installed at the lower end of the irregular frame, a force-bearing rod is inserted into the insertion cylinder, and a bolt is threaded onto the outer ring wall of the insertion cylinder, with the bolt abutting against the force-bearing rod.

[0013] Preferably, the fertilizer bin is fixedly installed at the center of the arc-shaped shovel, and the fertilizer bin is a triangular prism. A fertilizer channel communicating with the fertilizer bin is fixedly installed on the force-bearing rod. The fertilizer channel is connected to the fertilizer storage tank.

[0014] Preferably, the irrigation pipe is fixedly installed at the edge of the arc-shaped shovel, and several water outlet holes are opened on the irrigation pipe. A central nozzle is fixedly installed at the lower end of the expansion block. The irrigation pipe and the corresponding central nozzle are connected by a connecting pipe. The central nozzle and the irrigation pipe are connected to the water storage tank.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: the curved shovel is inserted into the soil and expands outward, locally cultivating the soil around the roots to form a loose root zone environment. At this time, water and fertilizer are supplied simultaneously, allowing fertilizer and water to be delivered directly to the vicinity of the roots, promoting crop absorption, achieving precise supply to the root zone, reducing deep seepage of water and fertilizer and surface evaporation, and improving water and fertilizer utilization efficiency. Moreover, the moving module can adjust the relative position of each working unit to adapt to crops with different row spacing and plant spacing, ensuring that the curved shovel is accurately aligned with the soil around the plant and avoiding damage to the roots. Furthermore, the curved shovel can also be used to transplant seedlings without changing the working parts, making the equipment capable of both daily water and fertilizer management and transplanting and replanting, making its uses more flexible. In this way, the cultivation and loosening of soil, precise fertilization, root irrigation and transplanting operations are integrated into one, reducing the problem of seedling damage caused by repeated entry and exit of equipment in the field, and improving work efficiency.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 A water and fertilizer integrated machine for coordinated irrigation and fertilization includes a mobile frame 1 and a material carrier 2 fixed thereon. Several mobile modules 3 are slidably installed on the mobile frame 1 in a linear array.

[0030] The irrigation and fertilization mechanism 4 is located at the lower end of the mobile module 3. The irrigation and fertilization mechanism 4 includes a lifting component 41 located at the lower end of the mobile module 3. An expansion component 42 is located at the lower end of the lifting component 41. Several force-bearing rods 43 are arranged in a circular array on the expansion component 42. An arc-shaped shovel 44 is fixedly installed at the lower end of the force-bearing rods 43. A fertilizer bin 45 and an irrigation pipe 46 are arranged on the arc-shaped shovel 44.

[0031] The lifting component 41 inserts the arc-shaped shovel 44 into the soil around the plant. The expansion component 42 expands the arc-shaped shovel 44 outward to cultivate the soil. The fertilizer bin 45 and the irrigation pipe 46 apply fertilizer and water directly to the plant roots. The expansion component 42 retracts the arc-shaped shovel 44 inward to transplant the plant.

[0032] In actual operation, the irrigation and fertilization mechanism 4 adjusts its working position synchronously with the movement of the moving module 3. The expansion component 42 drives the force rod 43 and the arc-shaped shovel 44 to achieve radial expansion or contraction. The force rod 43 is made of metal rod, and the arc shape of the arc-shaped shovel 44 makes it easy to insert into the soil and reduce resistance.

[0033] During operation, the lifting component 41 is operated to make the arc-shaped shovel 44 move vertically downward and insert it into the soil around the plant roots. When the arc-shaped shovel 44 reaches the predetermined depth, the expansion component 42 is operated to move the force rod 43 outward, thereby causing the arc-shaped shovel 44 to expand outward, thus cultivating the soil around the plant roots and loosening the soil structure. After cultivation is completed, the pre-prepared fertilizer and water are directly delivered to the plant root area through the fertilizer bin 45 and irrigation pipe 46.

[0034] Furthermore, the expansion component 42 can also cause the force-bearing rod 43 to retract inward, driving the arc-shaped shovel 44 to converge inward. At this time, the arc-shaped shovel 44 can wrap the plant roots, thereby realizing the transplanting operation of the plant.

[0035] In this way, the linear sliding adjustment of the moving module 3 can adapt to different crop row spacings. The irrigation and fertilization mechanism 4 can insert the arc-shaped shovel 44 deep into the soil to directly cultivate, fertilize and irrigate the plant roots, improve water and fertilizer utilization, reduce surface runoff and environmental pollution. In addition, it can also complete seedling transplanting, simplify field management process and reduce operating costs.

[0036] Please see Figure 1 , Figure 2 and Figure 3 The mobile frame 1 includes two symmetrical triangular frames 11, and several positioning rods 12 are fixedly installed between the triangular frames 11. The mobile module 3 is slidably installed on the several positioning rods 12. The lower end of the triangular frame 11 is rotatably installed with tires 111 distributed in front and behind.

[0037] In actual operation, the tires 111 can drive the whole machine to move autonomously in the field, improving the flexibility of equipment operation and thus adapting to the irrigation and fertilization needs of different operating areas. Multiple positioning rods 12 provide sliding tracks and limiting bases for the moving module 3, so that the moving module 3 always moves in the preset direction during the adjustment of position, without deviation or jamming.

[0038] Please see Figure 2 A tractor 5 is fixedly installed at the front end of the material truck 2, and a fertilizer storage tank 21 and a water storage tank 22 are fixedly installed on the upper surface of the material truck 2.

[0039] In actual operation, the tractor 5 makes the entire water and fertilizer integrated machine a self-propelled, integrated mobile operating unit without the need for additional independent traction equipment. The fertilizer storage tank 21 and water storage tank 22 integrate the water and fertilizer storage functions with the whole machine, providing a stable and continuous water and fertilizer supply to the irrigation and fertilization mechanism 4 below.

[0040] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 The moving module 3 is provided with a drive assembly 31, which includes a first motor 311 fixedly installed on the moving module 3. One of the positioning rods 12 has a guide groove 312, and the guide groove 312 is connected to the first motor 311 through a rack and pinion transmission structure. The other positioning rods 12 have limit grooves 121, and the moving module 3 is provided with balls that are tactilely connected to the limit grooves 121.

[0041] In actual operation, when the first motor 311 is working, its output end is converted into linear movement of the moving module 3 along the positioning rod 12 through the meshing of gears and racks. This allows each moving module 3 to independently adjust its position automatically along the positioning rod 12. The limiting groove 121 and the ball bearings on the moving module 3 provide stable lateral support and guidance for the moving module 3, suppressing the swaying and vibration of the moving module 3 during movement, ensuring the smoothness of its sliding process and the accuracy of its direction. This improves the flexibility and operating efficiency of the water and fertilizer integrated machine to adapt to different row spacing or plant spacing, and enhances the applicability and intelligence level of the equipment.

[0042] Please see Figure 2 , Figure 3 and Figure 5 The moving module 3 is also provided with a locking component 32. The locking component 32 includes a central shaft 323 that is rotatably mounted on the moving module 3. A locking disc 321 that is symmetrically mounted on the central shaft 323 is fixedly mounted on the central shaft 323. A semi-circular pressure block 322 that corresponds one-to-one with the positioning rod 12 is fixedly mounted on the locking disc 321. A second motor 324 is fixedly mounted inside the moving module 3. The second motor 324 and the central shaft 323 are connected by a gear transmission structure.

[0043] In actual operation, after the moving module 3 is adjusted to the target position, the second motor 324 drives the central shaft 323 to rotate, which in turn drives the left and right symmetrical locking discs 321 and the semi-arc pressure block 322 on them to rotate synchronously, so that the semi-arc pressure block 322 is tightly pressed onto the positioning rod 12, thereby completing the position locking.

[0044] This improves the positional stability of the moving module 3, preventing the moving module 3 from shifting or moving along the positioning rod 12 due to vibration or external force during irrigation and fertilization operations, ensuring the arrangement accuracy of multiple work units, and guaranteeing the accuracy of irrigation, fertilization, and seedling transplanting operations.

[0045] Please see Figure 2 , Figure 3 , Figure 4 and Figure 7 The lifting assembly 41 includes a support frame 411 fixedly installed on the moving module 3, a hydraulic cylinder 412 fixedly installed inside the support frame 411, and a fixed plate 413 fixedly installed at the telescopic end of the hydraulic cylinder 412.

[0046] Please see Figure 2 , Figure 7 and Figure 8 The expansion assembly 42 includes a device frame 421 fixedly installed at the lower end of the fixed plate 413. Several hinge rods 422 are hinged in a circumferential array at the lower end of the device frame 421. A special frame 426 is hinged to the end of the hinge rod 422 away from the corresponding device frame 421. A third motor 423 is fixedly installed inside the device frame 421. A screw 424 is fixedly sleeved at the output end of the third motor 423. An expansion block 425 is threaded onto the screw 424. The expansion block 425 and the end of the hinge rod 422 away from the corresponding device frame 421 are hinged together to a push rod.

[0047] In actual operation, the hydraulic cylinder 412 can ensure that the arc-shaped shovel 44 overcomes soil resistance and smoothly and stably inserts into the soil layer at the preset depth, adapting to the operational requirements of different soil hardness, and ensuring that the lower structure of the entire irrigation and fertilization mechanism 4 smoothly completes the lifting action.

[0048] Specifically, the third motor 423 drives the screw 424 to rotate, and the screw 424 drives the expansion block 425 to move downward through a threaded connection. Since the expansion block 425 is hinged with all the hinge rods 422 through the push rod, the movement of the expansion block 425 can synchronously push or pull all the hinge rods 422, so that the irregular frame 426 and the arc-shaped shovel 44 connected to the hinge rods 422 can achieve synchronous outward expansion or inward contraction.

[0049] In addition, by precisely controlling the rotation of the third motor 423, the displacement of the expansion block 425 can be precisely controlled, thereby achieving fine adjustment of the expansion or contraction amplitude of the arc-shaped shovel 44. This allows the water and fertilizer integrated machine to flexibly adapt to the operational needs of plants of different sizes. When cultivating the soil, the expansion amplitude can be adjusted according to the distribution range of the plant roots to ensure that water and fertilizer are precisely applied to the roots.

[0050] During seedling transplanting, the shrinkage range can be adjusted according to the size of the seedlings to minimize damage to the young plants, thereby improving the efficiency and effectiveness of irrigation and fertilization coordination, and enhancing the success rate of seedling transplanting and its adaptability to different crops.

[0051] Please see Figure 7 An insertion cylinder 431 is fixedly installed at the lower end of the irregular frame 426. The force-bearing rod 43 is inserted into the insertion cylinder 431. A bolt 432 is threadedly connected to the outer ring wall of the insertion cylinder 431. The bolt 432 abuts against the force-bearing rod 43.

[0052] In actual operation, the force rod 43 is inserted into the insertion cylinder 431, leaving room for length adjustment. The length of the force rod 43 extending out of the insertion cylinder 431 can be flexibly changed according to the actual operation needs, thereby changing the distance between the arc-shaped shovel 44 and the special frame 426, realizing flexible adjustment of the working depth of the arc-shaped shovel 44 to adapt to the operation needs of plants with different root depths.

[0053] Bolt 432 abuts against the force-bearing rod 43. The threaded connection allows the operator to quickly rotate bolt 432 to loosen or lock the force-bearing rod 43. Once locked, the force-bearing rod 43 is fixed in position by the squeezing force of bolt 432, ensuring that the force-bearing rod 43 will not shift during operation and maintaining the stability of the working depth.

[0054] Please see Figure 2 , Figure 8 and Figure 9 The fertilizer bin 45 is fixedly installed at the center of the arc-shaped shovel 44, and the fertilizer bin 45 is a triangular prism. A fertilizer channel 451 connected to the fertilizer bin 45 is fixedly installed on the force rod 43. The fertilizer channel 451 is connected to the fertilizer storage tank 21. An electric push rod 452 is fixedly installed inside the fertilizer bin 45. A sealing cover 453 is fixedly installed at the telescopic end of the electric push rod 452. The sealing cover 453 corresponds to the opening at the lower end of the fertilizer bin 45.

[0055] In actual operation, fertilizer is continuously transported from fertilizer storage tank 21 to fertilizer application bin 45 through fertilizer channel 451 to ensure a stable supply of fertilizer. During the process of the arc-shaped shovel 44 being inserted into the soil, the sealing cover 453 remains closed to prevent premature leakage of fertilizer.

[0056] Once the curved shovel 44 reaches the predetermined fertilization depth, the electric push rod 452 drives the sealing cover 453 to open, allowing the fertilizer to be applied precisely and concentrated to the plant roots, thereby improving fertilizer utilization efficiency and solving the problem of inaccurate fertilizer application and easy waste.

[0057] The fertilizer bin 45 is installed at the center of the arc-shaped shovel 44 and adopts a triangular prism structure, which allows the fertilizer bin 45 to be accurately positioned in the root zone of the plant when the arc-shaped shovel 44 is inserted into the soil around the plant, while reducing insertion resistance.

[0058] Please see Figure 2 , Figure 8 and Figure 9 The irrigation pipe 46 is fixedly installed at the edge of the arc-shaped shovel 44. Several water outlet holes 461 are opened on the irrigation pipe 46. A central nozzle 463 is fixedly installed at the lower end of the expansion block 425. The irrigation pipe 46 and the corresponding central nozzle 463 are connected by a connecting pipe 462. The central nozzle 463 and the irrigation pipe 46 are connected to the water storage tank 22.

[0059] In practice, the irrigation pipe 46 is placed at the edge of the arc-shaped shovel 44, so that the irrigation pipe 46 can deliver water to the outer ring of the cultivated area, that is, the outer distribution area of ​​the plant roots, as the arc-shaped shovel 44 is inserted and expanded. The water is then evenly supplied to the outer ring through the water outlet 461. Taking advantage of the characteristic of the arc-shaped shovel 44 to penetrate deep into the soil, the irrigation water is directly delivered to the deep soil layer around the plant roots.

[0060] Meanwhile, the central sprinkler 463 is located at the center of the entire expansion irrigation operation structure, which can effectively supplement the water supply in the center of the cultivated area, thereby achieving uniform water supply to the entire cultivated area. This allows water to be fully and evenly delivered to the root system of all plant areas, improving the efficiency of water and fertilizer utilization, avoiding water and fertilizer waste and environmental pollution, and better cooperating with water and fertilizer synergy to meet the operational needs of accurately and evenly delivering water to the entire root system area.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
