Description

Technical Field

[0001] This utility model relates to the field of integrated water and fertilizer technology, specifically to a device for precise application of integrated water and fertilizer to citrus soil. Background Technology

[0002] Citrus is an important economic fruit tree in my country. Its growth cycle is long and its demand for water and nutrients has obvious stage characteristics. Traditional fertilization and irrigation methods mostly use manual broadcasting, furrow irrigation or fixed drip irrigation systems, which have many problems.

[0003] Current fertilization and irrigation methods cannot accurately control the amount of fertilizer applied each time, making it difficult to match the nutritional needs of citrus at different growth stages (such as the budding stage and the fruit expansion stage). Furthermore, water-soluble fertilizers are prone to sedimentation and clumping in containers, and traditional mixing methods result in uneven mixing, affecting the accuracy of fertilization. Therefore, we have proposed an integrated water and fertilizer precision application device for citrus soil. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a precision water and fertilizer application device for citrus soil, comprising a movable base, a mixing cylinder fixedly installed on the upper end of the movable base, an infusion pipe fixedly connected to the lower outer end of the mixing cylinder, a metering cylinder arranged near the mixing cylinder, and the infusion pipe communicating with the metering cylinder, a large gear rotatably connected to the bottom of the movable base, a small gear meshing with the outer circumference of the large gear, a nozzle fixedly connected to the lower end of the small gear through a connecting column, and an outlet pipe fixedly connected to the lower outer end of the metering cylinder, the outlet pipe passing through the small gear and communicating with the nozzle.

[0006] As a preferred embodiment of this utility model, a drive motor is fixedly installed at the top center of the mixing cylinder, and the output end of the drive motor is connected to a rotating shaft via a coupling. The lower end of the rotating shaft passes through the mixing cylinder and is fixedly connected to a large gear.

[0007] As a preferred embodiment of this utility model, a stirring rod is fixedly connected to the upper outer periphery of the rotating shaft, a spiral blade is fixedly connected to the outer periphery of the center end of the rotating shaft, and a scraper is fixedly connected to the lower end near the spiral blade.

[0008] As a preferred embodiment of this utility model, a filter screen is fixedly connected inside the mixing cylinder, and the upper end of the filter screen is in contact with the scraper rod. A guide plate is fixedly connected to the bottom wall of the mixing cylinder.

[0009] As a preferred embodiment of this utility model, a hydraulic rod is fixedly installed on the top of the metering cylinder, and a piston is fixedly connected to the output end of the hydraulic rod, and the piston is movably connected to the inside of the metering cylinder.

[0010] As a preferred embodiment of this utility model, the upper ends of both sides of the mixing cylinder are connected to feed cylinders, the tops of the two feed cylinders are rotatably connected to sealing caps via hinges, and the lower ends of the two feed cylinders are slidably connected to feed baffles.

[0011] As a preferred embodiment of this utility model, a one-way valve is fixedly installed on the outer periphery of the infusion tube, a one-way valve is fixedly installed on the outer periphery of the outlet tube, and a rotating door is rotatably connected to the top of the mixing cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. This citrus soil precision water and fertilizer integrated device uses a hydraulic rod to drive a piston to reciprocate in a metering cylinder, which can precisely control the amount of fertilizer applied each time. This avoids the problems of uneven, excessive or insufficient application of fertilizer in traditional manual fertilization, meets the differentiated nutrient requirements of citrus at different growth stages, and improves the scientific nature of fertilization and crop quality.

[0014] 2. This citrus soil precision water and fertilizer integration device adopts a mixed structure with the synergistic action of a stirring rod and a spiral blade. The stirring rod fully mixes the water and fertilizer, while the spiral blade pushes the upper mixed liquid downward to promote liquid circulation, effectively prevent fertilizer sedimentation or clumping, ensure uniform water and fertilizer solution, and improve fertilizer utilization rate.

[0015] 3. This citrus soil precision water and fertilizer integrated device uses a large gear and a small gear meshing to drive the nozzle to rotate around its own axis, achieving circular spraying. This ensures that the water and fertilizer solution is evenly distributed in the root zone soil within the drip line range of the citrus tree, avoiding excessively high local concentrations or fertilization blind spots, and improving root absorption efficiency. This utility model has a simple and reasonable structure, novel design, and is easy and convenient to operate, and has high practical value. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, this utility model discloses a precision water and fertilizer application device for citrus soil, comprising a movable base 1, a mixing cylinder 2 fixedly installed on the upper end of the movable base 1, an infusion pipe 3 fixedly connected to the lower outer side of the mixing cylinder 2, a metering cylinder 4 arranged near the side of the mixing cylinder 2, and the infusion pipe 3 communicating with the metering cylinder 4, a large gear 5 rotatably connected to the bottom of the movable base 1, a small gear 6 meshing with the outer periphery of the large gear 5, a nozzle 7 fixedly connected to the lower end of the small gear 6 through a connecting column, and an outlet pipe 8 fixedly connected to the lower outer side of the metering cylinder 4, and the outlet pipe 8 passing through the small gear 6 and communicating with the nozzle 7.

[0025] The mixing cylinder 2 is fixedly installed with a drive motor 9 at the top center end. The output end of the drive motor 9 is connected to a rotating shaft 10 through a coupling. The lower end of the rotating shaft 10 passes through the mixing cylinder 2 and is fixedly connected to the large gear 5. The drive motor 9 provides the power source for the entire device. The linkage control of stirring and mixing and the rotation of the nozzle 7 is realized simultaneously through a single rotating shaft 10. The structure is compact and the transmission efficiency is high.

[0026] The upper outer periphery of the rotating shaft 10 is fixedly connected to a stirring rod 11, the outer periphery of the center end of the rotating shaft 10 is fixedly connected to a spiral blade 12, and the lower end near the spiral blade 12 is fixedly connected to a scraper 13. The stirring rod 11 is used to fully stir the water and fertilizer to promote dissolution; the spiral blade 12 rotates with the rotating shaft 10 to push the mixture downward; and the scraper 13 is used to remove impurities from the surface of the filter screen 14 to prevent clogging.

[0027] The mixing cylinder 2 is fixedly connected to a filter screen 14, and the upper end of the filter screen 14 is in contact with the scraper 13. The bottom wall of the mixing cylinder 2 is fixedly connected to a guide plate 15. The filter screen 14 is used to intercept undissolved particles to ensure the smooth flow of subsequent pipelines. The guide plate 15 is set at an angle to guide the mixed liquid to flow in a concentrated manner towards the infusion pipe 3 to avoid liquid accumulation at the bottom.

[0028] The metering cylinder 4 is fixedly equipped with a hydraulic rod 16 at the top. The output end of the hydraulic rod 16 is fixedly connected to a piston 17, and the piston 17 is movably connected to the inside of the metering cylinder 4. The hydraulic rod 16 drives the piston 17 to reciprocate, thereby realizing the precise extraction and quantitative delivery of the water-fertilizer mixture, ensuring that the amount of fertilizer applied each time is consistent and meeting the needs of precision agricultural management.

[0029] The mixing cylinder 2 has feeding cylinders 18 connected to the upper ends of both sides. The top of each feeding cylinder 18 is connected to a sealing cover 19 by a hinge. The lower ends of each feeding cylinder 18 are slidably connected to a feeding baffle 20. Water and fertilizer are added through the feeding cylinders 18 respectively. The sealing cover 19 can prevent liquid from splashing out or dust from entering during the feeding process. The feeding baffle 20 can control the timing of material feeding, making the operation flexible and convenient.

[0030] One-way valve 21 is fixedly installed on the outer periphery of the infusion pipe 3, and one-way valve 22 is fixedly installed on the outer periphery of the outlet pipe 8. A rotating door 23 is rotatably connected to the top of the mixing cylinder 2. One-way valve 21 and one-way valve 22 prevent backflow of the mixed liquid during the transportation process and ensure stable system pressure. The rotating door 23 can be opened to clean or maintain the inside of the mixing cylinder 2, thereby improving the maintainability and service life of the equipment.

[0031] Working principle: When in use, push the device to the vicinity of the root of the citrus tree to be fertilized via the movable seat 1, and adjust the position so that the nozzle 7 is aligned with the drip line area. Open the sealing caps 19 on the two feed cylinders 18, add appropriate amounts of clean water and water-soluble fertilizer respectively, close the sealing caps, open the feed baffle 20 to let the material fall into the mixing cylinder 2, start the drive motor 9 to drive the rotating shaft 10 to rotate, the stirring rod 11 on it to fully stir the water and fertilizer, and the spiral blade 12 pushes the upper layer of mixture downward to promote the flow of liquid to the bottom of the mixing cylinder 2, improve the fertilizer mixing efficiency, and make the fertilizer fully stirred. After being filtered by the filter screen 14, start the hydraulic rod 16 to drive the piston 17 to move upward, and draw the liquid into the metering cylinder 4 through the infusion pipe 3 and the one-way valve 21. When the piston 17 moves downward, the liquid in the metering cylinder 4 can be forced into the nozzle 7 through the outlet pipe 8 and the one-way valve 22. Simultaneously, the rotating shaft 10 drives the large gear 5 to rotate synchronously, which in turn drives the small gear 6 and its connected nozzle 7 to rotate around their own axis through gear meshing, achieving uniform ring-shaped spraying. During the mixing process, the scraper 13 continuously scrapes away impurities from the surface of the filter screen 14 to prevent clogging. After the operation is completed, the motor and hydraulic system are turned off, and the device is moved to the next work point to repeat the above process.
