Description

Technical Field

[0001] This invention relates to the field of grape cultivation technology, and in particular to a grape cultivation irrigation device for improving the firmness of grape fruits. Background Technology

[0002] The firmness of fresh grapes directly determines their storage and transportation period, shelf appearance, and commercial grading value after harvest. Soil moisture supply during the pit hardening stage to the ripening stage regulates the cell wall fibrosis process, optimizes skin density and pulp structure, and a stable water and fertilizer supply model is the core cultivation management method for improving grape firmness and reducing storage and transportation losses. With the continued popularization of large-scale vineyard planting models in China, supporting irrigation equipment systems are constantly iterating and upgrading to meet the demands of refined cultivation management. The entire irrigation pipeline system, water and fertilizer mixing components, and field layout structure have all undergone standardized processing and construction processes. The pipes are made of modified plastic materials resistant to sun aging and water and fertilizer corrosion, suitable for long-term open-air service environments in orchards. All irrigation components have undergone long-term field testing, demonstrating excellent structural stability and long-term performance.

[0003] Chinese patent CN115191334B discloses a water-saving irrigation device for grapes. By inserting the bottom end of the irrigation pipe into the soil for irrigation, the roots of the grapevines can absorb water more effectively and comprehensively, improving the irrigation effect on the grapevines. This avoids direct irrigation, which can cause some water to evaporate or be absorbed by the soil far away from the grapevines, thus effectively saving water resources. Moreover, the irrigation device is easy to move and can be used to irrigate grapevines that need irrigation, which also has the effect of saving water resources.

[0004] While the above methods can achieve precise irrigation of grape roots and reduce water evaporation losses, they are insufficient for improving grape fruit firmness. Without pre-mixed, evenly applied calcium and magnesium water-soluble fertilizers, the firmness of the grapes cannot be guaranteed. Furthermore, the drill bit, constantly in contact with soil and stones during root drilling, is prone to wear and tear, significantly increasing drilling resistance. Replacing the drill bit requires complete disassembly, impacting irrigation efficiency. Soil particles can easily clog the irrigation inlet during drilling, affecting the delivery of irrigation water and fertilizer. After irrigation, root hypoxia may impair root respiration, hindering nutrient absorption and preventing the full absorption and utilization of calcium and magnesium by the roots to improve fruit firmness. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides the following technical solution: A grape cultivation irrigation device for improving grape fruit firmness, comprising a walking frame, a clear water tank and a mixing device fixedly connected to the top of the walking frame, a first water pump and a second water pump respectively connected to the sides of the clear water tank and the mixing device, the outlets of the first water pump and the second water pump respectively connected to a first diversion pipe and a second diversion pipe, a fixed part of a lateral drive assembly fixedly connected to the top of the walking frame, an irrigation mechanism fixedly connected to the movable part of the lateral drive assembly, and a three-way reversing valve fixedly connected to the top of the walking frame, the two inlets of the three-way reversing valve respectively connected to the first diversion pipe and the second diversion pipe, and the outlet of the three-way reversing valve...

The mixing rod passes through the conical guide column and the second baffle plate respectively and is rotatably connected to them. A guide scraper is evenly fixedly connected to the portion of the mixing rod above the conical receiving plate via a bracket. A connecting rod is disposed above the conical guide column. Multiple sets of the connecting rod are disposed and fixedly connected to the mixing rod. A mixing scraper is fixedly connected to the end of the connecting rod away from the mixing rod. One side of the mixing scraper is in contact with the side of the filter cylinder. Arc-shaped stirring plates are installed on the rod between the first and second partitions and between two adjacent sets of the second partitions. The arc-shaped stirring plates have evenly spaced crushing and stirring ports. The bottom of the stirring tank is fixedly connected to the top of the walking frame. The bottom side of the stirring tank is connected to the inlet of the second water pump. Sugar alcohol calcium and other fertilizers and clean water are put into the device. The stirring motor drives the stirring components at each stage to operate. The scraper removes the material adhering to the cylinder wall, and the filter retains the undissolved fertilizer to complete the first stage of dissolution. Then, the arc-shaped stirring plates and cutting structure are used for multi-stage crushing and stirring to fully dissolve the fertilizer and prepare a fertilizer solution with uniform concentration. The entire multi-stage dissolution structure has a fast mixing speed and uniform mixing, and provides a stable supply of calcium fertilizer solution to ensure nutrient absorption during the hardening period of grapes and effectively improve the firmness of grape fruits.

[0007] Preferably, the irrigation mechanism includes a connecting horizontal plate, the top of which is symmetrically and fixedly connected to the fixed end of an electric lifting rod. The movable end of the electric lifting rod passes through the top of the horizontal plate and is fixedly connected to a fixed horizontal plate. An irrigation pipe passes through and is rotatably connected to the top of the fixed horizontal plate. A drill bit assembly is fixedly connected to the bottom of the irrigation pipe. A rotating sleeve passes through and is rotatably connected to the top of the irrigation pipe. The inner wall of the rotating sleeve is symmetrically provided with guide grooves.

A driving part of a rotating assembly for driving the irrigation pipe to rotate is fixedly connected to the irrigation pipe. The fixed part of the rotating assembly is fixedly connected to a fixed cross plate via a bracket.

[0009] Preferably, the fixed end of an elastic telescopic rod is uniformly fixedly connected to the inner wall of the irrigation pipe, and a connecting vertical plate is fixedly connected to the movable end of the elastic telescopic rod. A sealing rod is fixedly connected to the side of the connecting vertical plate located on one side of the elastic telescopic rod. The sealing rod is slidably connected to the inner wall of the irrigation inlet. A wedge-shaped platform is fixedly connected to the side of the connecting vertical plate away from the elastic telescopic rod. A conical sleeve for pressing the wedge surface of the wedge-shaped platform is sleeved and fixedly connected to the telescopic pipe. The top of the connecting horizontal plate is fixedly connected to the movable part of the horizontal drive component through a bracket. The top of the annular water inlet tank is connected to the water delivery pipe. After moving to the root of the grapevine, the drill bit drills into the soil layer to implement deep underground irrigation. During the drilling stage, the sealing rod closes the water outlet, and the expansion roller prevents soil from clogging the pipeline. After reaching the root system, the control component opens the water outlet. The water path is switched according to different growth stages of the grapevine. Clean water is used for daily watering, and the prepared calcium-containing fertilizer water is directly delivered to the deep soil layer of the roots, which greatly improves the calcium absorption efficiency, improves fruit firmness from the nutrient supply level, and solves the problem of large evaporation loss from surface irrigation.

[0010] Preferably, the drill bit assembly includes a connecting platform, which has an installation groove and a sealing groove. An installation post is threadedly connected to the inner wall of the installation groove, and the mounting platform is fixedly connected to the top of the installation post. A sealing ring is fixedly connected to the inner wall of the sealing groove, and a plug ring is fixedly connected to the bottom of the mounting platform. The plug ring is slidably connected to the inner wall of the sealing groove. The drill bit body is fixedly connected to the bottom of the connecting platform. A clearance groove is provided on the side of the connecting platform, and an installation bolt is threadedly connected through and through the inner wall of the clearance groove. One end of the installation bolt, passing through the clearance groove, is threadedly connected to the installation post. The top of the mounting platform is fixedly connected to the bottom of the irrigation pipe. The drill bit body is double-locked and fixed by the mounting post and the installation bolt. The plug ring and sealing ring seal the assembly gaps to prevent irrigation water leakage and structural loosening. When the drill bit is worn, the installation bolt can be loosened to unscrew the drill bit for disassembly and replacement. During assembly, the clearance groove can prevent damage to the bolts from drilling operations. The disassembly and maintenance process is simple and quick, ensuring continuous and stable operation of deep drilling irrigation, providing long-term water and fertilizer supply for grapes, and stabilizing fruit quality.

[0011] Preferably, the telescopic pipe includes a pipe body with air jets evenly distributed on its side. A sliding cylinder is slidably connected to the inner wall of the pipe body, and a connecting port is evenly distributed on the side of the sliding cylinder.

The side of the pipe body is fixedly connected to a conical sleeve, and the side of the pipe body is slidably connected to the inner wall of a guide groove via a sliding key. The top of the side of the pipe body is connected to the end of the air supply pipe away from the air pump. During irrigation, the sliding cylinder blocks the air jets to prevent backflow and leakage of water and fertilizer. After irrigation, the hydraulic mechanism drives the sliding cylinder to move downward, and the connecting port communicates with the air jet. The air pump outputs high-pressure air to be introduced into the soil around the roots, loosening the soil, increasing the oxygen content of the roots, and enhancing the efficiency of aerobic respiration and calcium absorption of the roots. After the air supply is completed, the sliding cylinder resets and seals the air jets. The water and air channels in the pipeline are isolated from each other and do not interfere with each other, ensuring the long-term stable operation of the entire irrigation system and further optimizing the firmness and quality of the grapes.

[0012] The beneficial effects of the technical solution provided by this invention include:

[0013] 1. This grape cultivation irrigation device, used to improve grape fruit firmness, is equipped with a mixing and stirring device. Targeting the calcium and magnesium water-soluble fertilizers required for improving grape fruit firmness, it achieves step-by-step dissolution, agglomeration, and fine pulverization of the fertilizer through a multi-stage layered mixing, guiding scraping, and filter screen structure. This avoids the problems of uneven dissolution and low efficiency associated with manual mixing. The multi-stage extended mixing path ensures uniform and stable fertilizer and water concentration, enabling rapid and precise mixing. This guarantees a balanced supply of fertilizer and water nutrients during the fruit enlargement and hardening stages, preventing concentration deviations from affecting cell wall development and steadily improving grape fruit firmness.

[0014] 2. This grape cultivation irrigation device, designed to improve grape fruit firmness, is equipped with an irrigation mechanism and employs a deep-targeted irrigation mode. This avoids the problem of high evaporation loss associated with traditional surface irrigation. By inserting the drill bit deep into the root soil, water and fertilizer are directly applied, significantly improving water and fertilizer absorption efficiency. It can also switch between clear water irrigation and calcium-containing fertilizer irrigation modes according to different growth stages of the grapes, precisely adapting to the growth needs of fruit setting, fruit enlargement, and pit hardening stages, and specifically supplementing calcium. At the same time, the drilling process automatically seals the irrigation inlet and supports the holes to prevent blockage, ensuring smooth irrigation and facilitating the accumulation of calcium in the grapes, further improving fruit firmness.

[0015] 3. This grape cultivation irrigation device for improving grape fruit firmness is equipped with a drill bit assembly and adopts a detachable double-fixed sealing structure. Through bolt limiting and ring sealing, the drill bit body can be quickly disassembled, replaced, and maintained. The operation is convenient and does not require complicated procedures. The sealing structure can effectively seal the connection gaps, prevent irrigation water and fertilizer leakage that could cause structural loosening, ensure stable and smooth drilling operations, and allow for timely replacement of worn drill bits, avoiding the problem of decreased drilling efficiency. This ensures the continuity of water and fertilizer irrigation operations and thus guarantees the stability of fruit firmness improvement.

[0016] 4. This grape cultivation irrigation device, used to improve grape fruit firmness, is equipped with a telescopic pipe that allows for ventilation and oxygenation. After irrigation, the internal structure of the telescopic pipe, combined with multi-stage hydraulic rods, automatically opens the air jet path to introduce compressed air into the root soil. This effectively loosens the soil, increases root oxygen content, promotes aerobic respiration in grape roots, strengthens the root system's ability to absorb calcium and water fertilizer, accelerates nutrient accumulation, and further consolidates and improves grape fruit firmness. During irrigation, the air jet can be automatically closed to prevent fertilizer and water leakage. Thus, it can optimize the root zone growth environment without affecting normal irrigation operations, further improving the firmness of mature grape fruit. Attached Figure Description

[0026] For the first embodiment, please refer to... Figures 1-3This invention provides a grape cultivation irrigation device for improving grape fruit firmness. By incorporating a mixing device 3, and applying calcium-containing fertilizer during the grape fruit enlargement and hardening stages to enhance cell wall strength and increase fruit firmness, the device utilizes a water-soluble fertilizer containing sugar alcohol calcium, potassium dihydrogen phosphate, and a small amount of sugar alcohol magnesium. The fertilizer is added through the feeding nozzle 32, while clean water is simultaneously introduced through the water supply pipe 33. The fertilizer and water fall onto the conical receiving plate 35. Simultaneously, the stirring motor 34 operates, driving the stirring rod 311 to rotate. The stirring rod 311 then... The guide scraper 312 rotates, evenly scraping the raw material falling on the conical receiving plate 35 towards the central opening. The raw material then falls onto the conical guide column 38 and, under the conical structure of the guide column 38, further diffuses into the mixing area formed between the first partition plate 36 and the filter cylinder 37. After the raw material falls into this area, the stirring rod 311 drives the stirring scraper 314 to rotate via the connecting rod 313, performing primary mixing of the fertilizer and water in this area. Simultaneously, the stirring scraper 314 moves along the side of the filter cylinder 37, removing the fertilizer adhering to the filter cylinder. The raw materials on filter cylinder 37 are scraped off to prevent uneven fertilizer-water ratio and blockage. After primary stirring and dissolution, the fertilizer-water mixture passes through filter cylinder 37 and enters below the first partition 36. Undissolved fertilizer blocks remain in the stirring area for further stirring and dissolution. The fertilizer-water mixture after primary stirring and dissolution falls below the first partition 36 and enters the stirring area between the first partition 36 and the lower second partition 39. The stirring rod 311 drives the arc-shaped stirring plate 315 in this area to rotate, and the arc-shaped stirring plate 315 performs secondary stirring of the fertilizer-water mixture, accelerating fertilizer dissolution while removing undissolved fertilizer blocks. The completely dissolved fertilizer block is broken up by the edge of the crushing and mixing port 316 to accelerate dissolution. After secondary mixing, the fertilizer solution enters the next mixing area through the extended port 310 for further mixing. After multiple mixing and dissolutions, the fertilizer is completely dissolved, resulting in a fertilizer solution with uniform composition. This ensures that the concentration of the fertilizer solution is uniform and stable, avoiding uneven nutrient solution concentration from affecting the fertilization effect and further affecting the improvement of fruit firmness. At the same time, it can quickly mix and evenly dissolve the nutrient solution in emergencies, avoiding the uneven and slow manual mixing that affects the efficiency of irrigation and fertilization.

[0027] For the second embodiment, please refer to... Figures 1-5By incorporating an irrigation mechanism 9, during routine irrigation of the grapevine root soil, the horizontal drive component 8 moves the entire irrigation mechanism 9 to the location of the grapevine roots requiring irrigation. Then, the electric lifting rod 92 pushes the fixed horizontal plate 93 downwards, simultaneously activating the rotating component 913 to rotate the irrigation pipe 94. The irrigation pipe 94 drives the drill assembly 98 to rotate downwards and drill, directly irrigating the soil near the grapevine roots. This avoids the problem of poor irrigation efficiency caused by water evaporation during traditional surface soil irrigation. When the drill assembly 98 drills, because its overall diameter is larger than the diameter of the upper irrigation pipe 94, and simultaneously, when the fixed expansion roller 912 drills into the soil, it can... The drill bit assembly 98 provides support for the hole drilled, reducing the adhesion of excavated soil to the irrigation inlet 911 and preventing blockage, thus ensuring smooth irrigation. Simultaneously, during drilling, the sealing rod 916 continuously seals the irrigation inlet 911 under the constant pressure of the conical sleeve 918, preventing soil from entering the irrigation pipe 94 and causing blockage, ensuring unobstructed irrigation. When drilling reaches near the root, the first-stage movable end of the multi-stage hydraulic rod 99 pushes the telescopic tube 97 downwards along the guide groove 96. The telescopic tube 97 drives the conical sleeve 918 downwards. After the conical sleeve 918 moves downwards, it no longer presses against the wedge surface of the wedge platform 917, at which point the elastic telescopic rod 914 releases. The elastic force drives the connecting vertical plate 915 to move towards the telescopic pipe 97. The connecting vertical plate 915 drives the sealing rod 916 to be pulled out from the irrigation port 911, making the irrigation port 911 connected to the inside of the irrigation pipe 94. At this time, the three-way reversing valve 10 is opened, and nutrient solution or clean water can be introduced into the annular water inlet tank 910 through the water delivery pipe 11, and then into the irrigation pipe 94. It flows out from the irrigation port 911 and directly irrigates the deep soil of the grape roots. The water can be directly absorbed by the roots, improving the effect of irrigation and fertilization, and is more conducive to promoting the absorption of calcium elements by grapes, thereby improving the firmness of the fruit. In the early stage of fruit setting and the early stage of fruit enlargement, the three-way reversing valve 10 is used to switch to the inlet of the first diversion pipe 6, using the first water... Pump 4 delivers clean water from water tank 2 to annular inlet tank 910 via water pipe 11. The clean water then enters irrigation pipe 94 through annular inlet tank 910 and flows out from irrigation outlet 911, providing deep irrigation to the grape roots and meeting the grape's water requirements. When calcium-containing fertilizer is applied to improve fruit firmness during the hardening stage, the three-way reversing valve 10 is switched to the inlet of the second branch pipe 7. The second water pump 5 delivers the uniform calcium-containing fertilizer solution prepared by mixing device 3 to irrigation pipe 94, which then flows directly from irrigation outlet 911 into the deep soil around the grape roots. This allows the grape roots to directly absorb the fertilizer solution, improving calcium absorption efficiency and effectively increasing fruit firmness.

[0028] Third embodiment, please refer to Figures 1-7By incorporating the drill bit assembly 98, when the drill bit body 988 wears out after prolonged use and requires replacement or maintenance, the mounting bolts 9810 are loosened to release the limiting fixation between the mounting post 984 and the connecting platform 981. Then, rotating the mounting post 984 allows it to be unscrewed from the mounting groove 982, quickly separating the drill bit body 988 from the mounting platform 985. After replacing the drill bit body 988, the mounting post 984 is aligned with the mounting groove 982 and screwed in, causing the insertion ring 987 to be inserted into the sealing groove 983 and pressing the sealing ring 986 to complete the seal. This prevents irrigation water from leaking from the connection point during irrigation after drilling. The connection between the mounting column 984 and the connecting platform 981 was loosened. Finally, the mounting bolt 9810 was inserted into the clearance groove 989 and tightened. The mounting column 984 was then fixed in place again, completing the double-fixed installation of the drill bit body 988. The clearance groove 989 prevents the drill bit assembly 98 from damaging the mounting bolt 9810 during drilling, ensuring smooth drilling operations. This allows the drill bit assembly 98 to be quickly disassembled, replaced, and maintained, preventing a decrease in drilling efficiency due to drill bit wear, which would affect the overall irrigation progress. This ensures that the irrigation device can stably and continuously carry out deep irrigation and fertilization operations, continuously providing suitable water and fertilizer conditions for the grapes, and ensuring the effect of improving fruit firmness.

[0029] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 By incorporating a telescopic pipe 97, during irrigation with clean water or fertilizer, air can be introduced into the soil after irrigation to enhance the absorption of water and calcium by the grape roots. This increases the oxygen content of the soil around the roots, preventing oxygen deficiency and thus improving the root absorption efficiency of calcium. During irrigation, the air jet 972 is always shielded by the side wall of the sliding cylinder 973, preventing water or fertilizer from entering the pipe 971 and overflowing from the outside. After irrigation, the secondary movable end of the multi-stage hydraulic rod 99 drives the sliding cylinder 973 downward through the connecting frame 975. After the sliding cylinder 973 moves downward, the connecting port 974 aligns and connects with the air jet 972, and the air pump 13 starts, supplying compressed air through... The air supply pipe 14 enters the pipe body 971. Compressed air is ejected from the jet nozzle 972 through the connecting port 974. The compressed air flows downward along the irrigation pipe 94 and flows out from the open irrigation port 911 into the surrounding soil. This loosens the soil and increases the air content of the soil around the roots, promoting root respiration, enhancing the roots' ability to absorb water and fertilizer, further promoting calcium accumulation, and further improving the firmness of the ripe fruit. When air supply is not needed, the secondary movable end of the multi-stage hydraulic rod 99 retracts, causing the sliding cylinder 973 to move upward, causing the connecting port 974 to be misaligned with the jet nozzle 972. The sliding cylinder 973 blocks and seals the jet nozzle 972, preventing fertilizer and water from entering the pipe body 971 and causing leakage during irrigation, thus ensuring the long-term stable operation of the irrigation device.

[0030] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
