Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to an integrated fertilization and irrigation device for green agriculture. Background Technology

[0002] The concept of green agriculture generally refers to the need to embody advantages such as economy, speed, and low pollution throughout the entire agricultural operation process. In terms of fertilization and irrigation, this can be reflected in the following two aspects: First, solid fertilizers should be buried at a certain depth in the soil to avoid direct application to the soil surface, which would result in significant fertilizer loss. Second, whether it is solid fertilizer, liquid fertilizer, or ordinary irrigation water, the application location should correspond to the plant location as closely as possible. Fertilizer and water should be added near the plant roots or sprayed specifically onto the leaves, avoiding excessive amounts of fertilizer and water being spilled on roads or in ditches.

[0003] On the other hand, the existing common integrated fertilization and irrigation devices mainly include a variable pipeline. When the pipeline is connected to the water tank, it is in the watering state, and when the pipeline is switched to the material tank, it is in the liquid fertilizer application state.

[0004] For example, Chinese utility model patent with patent publication number CN219068909U and publication date of May 26, 2023, discloses an integrated watering and fertilizing device for smart agriculture. Its structure includes: a support plate, a movable wheel, the movable wheel being fixedly installed at the bottom of the support plate, an adjustment device being provided on the right side of the support plate, a connecting plate being provided on the right side of the support plate, a motor being installed at the bottom of the connecting plate, a rotating rod being fixedly installed at the output end of the motor, a water spraying device being provided at the top of the support plate, the water spraying device including a connecting unit and a water spraying unit, and a control plate being fixedly installed on the left side of the box.

[0005] The integrated watering and fertilization device in this utility model patent has the following structure, principle and advantages: the spray head can be moved up and down intermittently by adjusting the device, thereby increasing the spraying range and spraying crops from different directions to improve the spraying effect; two solenoid valves ensure that irrigation water and liquid fertilizer can be sprayed out as needed, realizing the integrated effect of watering and fertilization.

[0006] However, in actual use, this device still has at least two shortcomings, which are also the technical problems that this invention aims to solve:

[0007] 1. It lacks the function of applying solid fertilizers and is only suitable for liquid fertilizers, which greatly reduces its practicality;

[0008] 2. Its nozzle structure can only adjust its own pitch angle, and can only tilt upwards to spray with a relatively small amplitude. When facing fruits and vegetables such as grapes and loofahs directly above, there will be problems with incomplete spraying.

[0009] Therefore, in summary, there is an urgent need for a new type of integrated fertilization and irrigation device that can both spread solid fertilizer and spray it vertically upwards, for use in green agriculture models. Summary of the Invention

[0010] This invention provides an integrated fertilization and irrigation device for green agriculture. By incorporating a water pump, nozzles, cylinders, a three-way pipe, a three-zone housing unit, a cover plate unit with a rod, and a rotating plate unit on the vehicle body, the following are achieved: 1. The cylinders, three-zone housing unit, and cover plate unit work together to ensure that solid fertilizer within the device can be spread downwards as needed; 2. The rotating plate unit drives the nozzles to rotate, with the nozzles having only two stable working states: horizontal and vertical, ensuring that fruits and vegetables on the sides and at higher elevations receive sufficient fertilization and irrigation.

[0011] The technical solution adopted by the present invention to solve the above problems is: an integrated fertilization and irrigation device for green agriculture, the structure of which includes a vehicle body plate, a water pump, a nozzle, a cylinder, and a three-way pipeline, and further includes a three-zone box unit set on the vehicle body plate for loading solid fertilizer, liquid fertilizer and irrigation water respectively, a cover plate unit with a rod set on the three-zone box unit and equipped with the water pump and cylinder for intermittently spreading solid fertilizer, and a rotating plate unit set on the cover plate unit with the nozzle and lifted upward by the cylinder to switch the spraying angle.

[0012] A further preferred technical solution is that the three-zone box unit includes a rectangular box disposed on the upper surface of the vehicle body panel, two partitions disposed inside the rectangular box, and a dispensing hole disposed on the bottom plate of the rectangular box and inserted into the rod cover plate unit.

[0013] A further preferred technical solution is that the rod-mounted cover unit includes a rectangular plate disposed on the upper surface of the rectangular box and with the cylinder disposed on the lower surface, an upper rod inserted into the rectangular plate and used to push the rotating plate unit upward, a shaft plate disposed on the lower end surface of the upper rod and connected to the cylinder, and a lower rod disposed on the lower surface of the shaft plate and inserted into the dispensing hole.

[0014] A further preferred technical solution is that the rod-mounted cover plate unit also includes a water pump mounting port disposed on the rectangular plate and exposed on the upper end face of the water pump for supporting the rotating plate unit.

[0015] A further preferred technical solution is that the rotating plate unit includes a perforated plate disposed on the upper surface of the rectangular plate, a circular tube inserted into the perforated plate, a right-angled fan-shaped plate disposed on the end face of the circular tube and having the nozzle thereon, and a flexible tube disposed inside the circular tube and connecting the water pump and the nozzle.

[0016] A further preferred technical solution is that the rotating plate unit further includes a pad block disposed on the rectangular side of the right-angled sector plate and used to fix the nozzle laterally by supporting the right-angled sector plate.

[0017] A further preferred technical solution is that: the rod-mounted cover plate unit further includes an opening disposed on the rectangular plate for inserting the upper rod; the rotating plate unit further includes a slide rail disposed on the rectangular side of the right-angled fan-shaped plate, engaging the pad, and blocking the opening when the nozzle sprays vertically by pushing the pad downwards onto the upper surface of the rectangular plate.

[0018] A further preferred technical solution is that the cross-sectional shape of the slide is T-shaped, and the rotating plate unit further includes a T-shaped locking block disposed on the pad.

[0019] A further preferred technical solution is that the three-zone box unit also includes a pipe hole disposed on the partition plate and used to insert and fix the three-way pipe.

[0020] A further preferred technical solution is that: the three-zone box unit further includes wire holes disposed on the rectangular box for installing the water pump and cylinder; the vehicle body plate is provided with a solid fertilizer spreading port, and the lower surface of the vehicle body plate is provided with a soil clearing plate.

Detailed Implementation

[0032] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0033] As attached Figure 1-7 As shown, an integrated fertilization and irrigation device for green agriculture includes a vehicle body plate 11, a water pump 12, a nozzle 13, a cylinder 14, and a three-way pipe 15. It also includes a three-zone box unit 1 mounted on the vehicle body plate 11 for loading solid fertilizer, liquid fertilizer, and irrigation water, respectively; a rod-mounted cover plate unit 2 mounted on the three-zone box unit 1 and equipped with the water pump 12 and the cylinder 14 for intermittently spreading solid fertilizer; and a rotating plate unit 3 mounted on the rod-mounted cover plate unit 2 and equipped with the nozzle 13, which is lifted upward by the cylinder 14 to switch the spraying angle.

[0034] In this embodiment, the water pump 12, nozzle 13, cylinder 14, and three-way pipe 15 are all commercially available products. The device equips the water pump 12 and cylinder 14 with independent power supplies. Furthermore, the three-way pipe 15 includes one three-way valve and three connecting pipes, which are respectively connected to the water pump 12, the liquid fertilizer area, and the irrigation water area, ensuring that the liquid fertilizer spraying operation and the irrigation operation can be controlled and selectively activated.

[0035] The "three zones" of the three-zone box unit 1 refer to the liquid fertilizer zone, the irrigation water zone, and the solid fertilizer zone. The solid fertilizer is spread by falling, and the interval and duration of the falling action are determined by the cylinder 14 and its matching controller.

[0036] Next, the "rod" structure of the rod-mounted cover unit 2 has at least the following two functions:

[0037] First, in the initial state of the device, the nozzle 13 is set horizontally and sprays towards the side. At this time, the "rod" structure repeatedly blocks and releases the solid fertilizer drop opening of the three-zone box unit 1 to ensure that the solid fertilizer falls in a controlled manner and is spread as needed.

[0038] Secondly, when the nozzle 13 needs to spray upwards, the "rod" structure retracts upwards significantly, thereby pushing or assisting in pushing the rotating plate unit 3 to rotate 90°. At this time, the nozzle 13 is facing upwards, ensuring that the fruits and vegetables at higher positions can receive sufficient spraying.

[0039] However, the following three points also need special explanation.

[0040] Firstly, the aforementioned "rod" structure can switch the orientation angle of the nozzle 13 by retracting upwards relatively quickly and then appropriately impacting the rotating plate unit 3. However, this places relatively high demands on the performance of the cylinder 14, and the "rod" structure wears out relatively quickly.

[0041] Secondly, when the nozzle 13 rotates from the upward position back to the side position, it can only be rotated manually, and the "rod" structure is invalid at this time.

[0042] Thirdly, when the "rod" structure controls and switches the rotating plate unit 3, if there is solid fertilizer in the three-zone box unit 1, a small amount of solid fertilizer will inevitably fall down.

[0043] The above three points are precisely the areas where this integrated fertilization and irrigation device needs further improvement.

[0044] Finally, the rotating plate unit 3 has only two stable states, corresponding to the nozzle 13, which means it can only be used horizontally or vertically and cannot be tilted. This ensures that the nozzle 13 is stable enough when spraying to the side or upwards and will not rotate or shift spontaneously.

[0045] The three-zone box unit 1 includes a rectangular box 101 disposed on the upper surface of the vehicle body plate 11, two partitions 102 disposed inside the rectangular box 101, and a dispensing hole 103 disposed on the bottom plate of the rectangular box 101 and inserted into the rod cover plate unit 2.

[0046] In this embodiment, the three areas—the liquid fertilizer area, the irrigation water area, and the solid fertilizer area—divided by the two partitions 102 are not geographically limited. However, the spreading hole 103 is definitely located in the solid fertilizer area, and the projections of the water pump 12, the cylinder 14, and the three-way valve are also definitely located in the solid fertilizer area.

[0047] The rod-mounted cover unit 2 includes a rectangular plate 201 disposed on the upper surface of the rectangular box 101 and with the cylinder 14 disposed on the lower surface, an upper rod 202 inserted into the rectangular plate 201 and used to lift the rotating plate unit 3 upward, a shaft plate 203 disposed on the lower end surface of the upper rod 202 and connected to the cylinder 14, and a lower rod 204 disposed on the lower surface of the shaft plate 203 and inserted into the dispensing hole 103.

[0048] In this embodiment, the cylinder 14 is vertically inverted and has a relatively large length, ensuring that the upper rod 202 can extend significantly above the rectangular plate 201, while the lower rod 204 can also fully block the dispensing hole 103.

[0049] In addition, a limiting rod can be sleeved on the shaft plate 203, and the limiting rod is fixedly installed on the lower surface of the rectangular plate 201.

[0050] Finally, the upper rod 202 and the lower rod 204 do not need to be aligned. Although both are controlled by the cylinder 14, their functions are completely different, which is quite ingenious.

[0051] The rod-mounted cover unit 2 also includes a water pump mounting port 205 disposed on the rectangular plate 201 and exposed on the upper end face of the water pump 12 to support the rotating plate unit 3.

[0052] In this embodiment, the water pump 12 is secured to the rectangular plate 201 via the water pump mounting port 205, ensuring that the upper end face of the water pump 12 can serve as the rotation endpoint of the rotating plate unit 3. This is highly efficient and can save one pad structure of the rotating plate unit 3.

[0053] Conversely, without the water pump 12 to support the rotating plate unit 3, the rotation angle of the rotating plate unit 3 would exceed 90°, making it impossible to simultaneously achieve the effects of fixed horizontal spraying and fixed vertical spraying.

[0054] The rotating plate unit 3 includes a perforated plate 301 disposed on the upper surface of the rectangular plate 201, a circular tube 302 inserted into the perforated plate 301, a right-angled fan-shaped plate 303 disposed on the end face of the circular tube 302 and provided with the nozzle 13, and a flexible hose 304 disposed inside the circular tube 302 and connecting the water pump 12 and the nozzle 13.

[0055] In this embodiment, the center of the right-angled sector plate 303 is the center of its rotation. This center cannot be directly set on the upper surface of the rectangular plate 201, so it must be raised. This is why the water pump 12 needs to be used as a side pad.

[0056] The openings on the perforated plate 301 are circular holes, and the center of the circular tube 302 is aligned with the center of the right-angled sector plate 303.

[0057] Furthermore, one end of the flexible hose 304 is connected to the water pump 12, and the other end is connected to the nozzle 13; its position is not particularly limited. However, the flexible hose 304 partially passes through the circular tube 302, which can prevent it from opening too wide or falling off, thus improving the structural compactness of the rotating plate unit 3.

[0058] Of course, neither end of the circular tube 302 is sealed, and it is optional whether or not a special pipe hole is opened on it for the flexible tube 304.

[0059] The rotating plate unit 3 also includes a pad 305 disposed on the rectangular side of the right-angled fan plate 303 and used to fix the nozzle 13 laterally by supporting the right-angled fan plate 303.

[0060] In this embodiment, the pad 305 serves the same purpose as the right-angled sector plate 303 of the water pump 12, ensuring that the two sides of the right-angled sector plate 303 are always one horizontal and one vertical.

[0061] The rod-mounted cover plate unit 2 further includes an opening 206 disposed on the rectangular plate 201 for inserting the upper rod 202; the rotating plate unit 3 further includes a slide 306 disposed on the rectangular side of the right-angled fan-shaped plate 303, engaging the pad 305, and blocking the opening 206 when the nozzle 13 sprays vertically by pushing the pad 305 downward onto the upper surface of the rectangular plate 201.

[0062] In this embodiment, the opening 206 ensures that the upper end of the upper rod 202 is exposed, thereby lifting the right-angled sector plate 303.

[0063] However, when the nozzle 13 sprays upwards, the opening 206 becomes harmful. At this time, the upper rod 202 has already detached downwards from the opening 206, and liquid can easily enter the directly exposed opening 206. Subsequently, the solid fertilizer becomes damp and clumps together, making it unable to fall and be spread.

[0064] Therefore, the pad 305 is made to be slidable. When the nozzle 13 sprays upwards, the pad 305 is manually pushed downwards until it falls on the upper surface of the rectangular plate 201 and seals the opening 206, thus preventing the solid fertilizer from getting damp.

[0065] It should be noted that the frictional resistance between the pad 305 and the slide 306 is set to be relatively large to ensure that the pad 305 cannot slide and shift spontaneously during the rotation of the right-angle sector plate 303, and needs to be manually pushed.

[0066] Finally, the pad 305 located on the upper surface of the rectangular plate 201 at this time is still the abutment part of the right-angled fan plate 303 to prevent it from rotating back. When the right-angled fan plate 303 needs to rotate to the nozzle 13 to be horizontal again, the pad 305 needs to slide and lift on the slide 306 first.

[0067] The slide rail 306 has a T-shaped cross-section, and the rotating plate unit 3 also includes a T-shaped locking block 307 disposed on the pad 305.

[0068] In this embodiment, the T-shaped locking block 307, in conjunction with the T-shaped slide, is one of the feasible ways for the pad block 305 to slide as needed.

[0069] In addition, the pad 305 is relatively thin, so that it will not touch the round tube 302 when it falls on the upper surface of the rectangular plate 201.

[0070] The three-zone box unit 1 also includes a pipe hole disposed on the partition plate 102 and used to insert and fix the three-way pipe 15.

[0071] In this embodiment, the aforementioned hole can adequately secure the tee pipe 15.

[0072] The three-zone box unit 1 also includes a wire hole 104 disposed on the rectangular box 101 and used for installing the water pump 12 and the cylinder 14; the vehicle body plate 11 is provided with a solid fertilizer spreading port 4, and the lower surface of the vehicle body plate 11 is provided with a soil clearing plate 5.

[0073] In this embodiment, a baffle plate is provided above the wire hole 104, and an independent power supply that simultaneously supplies power to the water pump 12 and the cylinder 14 is provided below it.

[0074] In addition, after the solid fertilizer is sown in the "soil clearing groove" at the front end of the solid fertilizer spreading port 4, the soil clearing plate 5 needs to be properly covered with soil to avoid a large amount of solid fertilizer loss.

[0075] The solid fertilizer spreading port 4 and the spreading hole 103 are aligned, with the former being larger than the latter.

[0076] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of the present invention. These are non-inventive modifications and are protected by patent law as long as they fall within the scope of the claims of the present invention.
