Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice planting technology, specifically to a nutrient solution sprinkler irrigation device for rice planting. Background Technology
[0002] During the growth and development of rice, it has strict and comprehensive requirements for a variety of nutrients. Macroelements such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, as well as microelements such as iron, manganese, zinc, copper, boron, and molybdenum, all need to be dissolved in nutrient solution and directly absorbed by the rice roots to maintain normal physiological metabolism and promote vigorous plant growth.
[0003] Currently, plant nutrient solution sprinkler irrigation technology has achieved certain results. For example, the plant nutrient solution sprinkler irrigation device disclosed in utility model patent CN213523076U effectively solves the problem of traditional sprinkler irrigation devices not being able to completely seal when not in use, leading to dust and debris entering the inlet pipe, through the coordinated work of components such as a water storage box, outlet, rotating shaft, cover plate, and snap-fit mechanism. However, this technology still has many limitations. First, it lacks a real-time stirring function. During the storage and transportation of nutrient solution, various nutrients are prone to precipitation or stratification due to their own characteristics, resulting in an imbalance between macro- and micro-elements in the sprayed nutrient solution. This makes it impossible to provide balanced and sufficient nutrients to the rice roots, greatly affecting the rice's effective absorption efficiency and making it difficult to guarantee high-quality and high-yield rice. Second, traditional sprinkler irrigation devices mostly rely on manual operation, which is not only labor-intensive but also inefficient, failing to meet the needs of large-scale and high-efficiency production in modern agriculture. Third, existing sprinkler irrigation equipment has a fixed working mode and cannot be flexibly adjusted according to different planting scenarios and nutrient solution supply methods. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides the following technical solution: A nutrient solution sprinkler irrigation device for rice cultivation, comprising a support unit, a power unit, and a mixing unit; the support unit includes a support bracket, on which a water inlet chamber and a water inlet pipe are provided, the water inlet chamber and the water inlet pipe being in communication; the power unit includes a power transmission column rotatably disposed within the water inlet chamber, a power spray pipe being disposed on the power transmission column, a first power gear being fixedly disposed on the power transmission column, the first power gear meshing with a second power gear fixedly disposed on the output shaft of a power motor to drive the power transmission column to rotate; the mixing unit includes a mixing drive wheel, the mixing drive wheel being rotatably disposed on a mixing mounting ring, a mixing plate being fixedly disposed on the mixing drive wheel, the mixing mounting ring being detachably disposed on a mixing box via threads, a mixing connector being disposed on the mixing box via a hose, a mixing delivery pump being disposed on the hose, and the mixing drive wheel being disposed on the second power gear via a power transmission belt.
[0005] Furthermore, a worm gear is provided on the power transmission column, and the worm gear meshes with the transmission part to drive the device to move.
[0006] Furthermore, the transmission unit includes a transmission worm wheel that meshes with the worm gear. The transmission worm wheel is rotatably mounted on the support bracket. A first transmission link is fixedly mounted on both sides of the transmission worm wheel. A second transmission link is rotatably mounted on the first transmission link. The other end of the second transmission link is rotatably mounted on a third transmission link. The third transmission link is rotatably mounted on a transmission shaft. A transmission wheel is fixedly mounted on the transmission shaft.
[0007] Furthermore, a transmission pawl is rotatably mounted on the transmission link three, and the transmission pawl is mounted on the transmission link three via a transmission return spring. A transmission stop post is fixedly mounted on the transmission link three to limit the position of the transmission pawl.
[0008] Furthermore, the transmission pawl slides into the transmission wheel to drive the transmission wheel to rotate.
[0009] Furthermore, one end of the support bracket is provided with a steering part for steering. The steering part includes a steering output frame rotatably mounted on the support bracket, a steering wheel rotatably mounted on the steering output frame, and the steering output frame is fixedly mounted on the output shaft of the steering motor.
[0010] Furthermore, the power transmission column has a hollow internal structure, and the power spray pipe is S-shaped.
[0011] The advantages of this utility model compared with the prior art are:
[0012] 1. This device achieves real-time stirring of the nutrient solution through the mixing section; when the power gear two rotates, it drives the mixing transmission wheel to rotate through the power transmission belt, thereby making the mixing plate rotate continuously. This ensures that various nutrients in the nutrient solution in the mixing box are evenly distributed, effectively avoiding the problem of imbalance caused by the precipitation or stratification of nutrient elements. It provides balanced and sufficient nutrients for the rice roots, greatly improving the effective absorption efficiency of nutrients by rice and providing a strong guarantee for high-quality and high-yield rice.
[0013] 2. This device employs a coordinated operation of the power unit, transmission unit, and steering unit. The power motor drives the power transmission column and power spray pipe to rotate, achieving uniform spraying of nutrient solution. Simultaneously, the rotating power transmission column drives the transmission worm wheel through the worm gear, which in turn drives the transmission wheel through the transmission connecting rod and transmission pawl, enabling automatic movement of the device. The steering motor drives the steering output frame to deflect the steering wheel, achieving precise control of the device's movement direction. No manual operation is required, significantly reducing labor intensity and greatly improving work efficiency, meeting the requirements of large-scale and high-efficiency production in modern agriculture.
[0014] 3. This device features two operating modes, allowing for flexible selection based on actual needs. Operating mode one is used when stirring and mixing the nutrient solution, ensuring uniformity through the mixing unit's stirring function. Operating mode two is used when no stirring is required and the device is directly connected to an external nutrient solution supply pipe. This combination meets the needs of different scenarios, effectively expanding the device's applicability and providing a more flexible and practical solution for nutrient solution irrigation in rice cultivation.

[0036] like Figures 1 to 16 As shown, the mixing unit 3 includes a mixing drive wheel 301, a mixing mounting ring 302, a mixing box 303, a mixing delivery pump 304, a mixing connector 305, and a mixing plate 306.

[0037] like Figures 1 to 16As shown, the transmission unit 1 includes a transmission worm gear 101, a first transmission link 102, a second transmission link 103, a third transmission link 104, a transmission return spring 105, a transmission stop post 106, a transmission pawl 107, and a transmission wheel 108.

The transmission pawl 107 slides with the transmission wheel 108 to drive the transmission wheel 108 to rotate.
[0038] like Figures 1 to 16 As shown, one end of the support bracket 401 is provided with a steering part 5 for steering. The steering part 5 includes a steering motor 501, a steering output frame 502, and a steering wheel 503. The steering output frame 502 is rotatably mounted on the support bracket 401, and the steering wheel 503 is rotatably mounted on the steering output frame 502. The steering output frame 502 is fixedly mounted on the output shaft of the steering motor 501, and the steering motor 501 is fixedly mounted on the support bracket 401. Both the power motor 204 and the steering motor 501 are waterproof motors.
[0039] like Figures 1 to 16 As shown, the nutrient solution sprinkler irrigation device for rice cultivation disclosed in this utility model has the following working principle:
[0040] Working Mode 1: The operator first removes the mixing installation ring 302 and mixing drive wheel 301 from the mixing box 303, then injects the nutrient solution into the mixing box 303, and then installs the mixing installation ring 302 and mixing drive wheel 301 back onto the mixing box 303. The operator places the device in the paddy field, rotates the mixing connector 305 to connect it to the carrying water inlet pipe 403, and turns on the power motor 204. The rotation of the power motor 204 drives the second power gear 205 to rotate, which in turn drives the power... When gear 203 rotates, the rotation of power gear 203 drives the power transmission column 202 and the power spray pipe 201 to rotate. When the power transmission column 202 and the power spray pipe 201 rotate, the mixing and delivery pump 304 is turned on. The mixing and delivery pump 304 pressurizes the nutrient solution in the mixing box 303 and delivers it to the power spray pipe 201 through the hose, mixing connector 305, bearing water inlet pipe 403, bearing water inlet chamber 402 and power transmission column 202, so that the nutrient solution is evenly sprayed onto the rice from the rotating power spray pipe 201, and the rice is evenly fertilized.
[0041] Simultaneously, the worm gear mounted on the rotating power transmission column 202 drives the transmission worm wheel 101 to rotate. The rotation of the transmission worm wheel 101 drives the first transmission link 102 to rotate. The rotation of the first transmission link 102, through the second transmission link 103, pulls the third transmission link 104 to swing. When the third transmission link 104 swings to the right, the transmission pawl 107 contacts the transmission wheel 108, and the transmission return spring 105 is stretched, causing the third transmission link 104 to move to the rightmost end. When the third transmission link 104 swings to the left to return to its original position, the transmission pawl 107 contacts the transmission wheel 108. When the transmission wheel 108 contacts, the transmission pawl 107 is restricted in position by the transmission blocking post 106 and cannot rotate. As the transmission connecting rod 104 swings, it drives the transmission pawl 107 to rotate the transmission wheel 108, thereby realizing the movement of the device. That is, while the device moves, nutrient solution is applied evenly to the rice. The steering motor 501 drives the steering output frame 502 to deflect the steering wheel 503, thereby controlling the direction of movement of the device. No manual operation is required, and nutrient solution is sprayed on the rice from all directions.
[0042] While the second power gear 205 rotates, it drives the mixing drive wheel 301 to rotate through the power transmission belt 206. The rotation of the mixing drive wheel 301 drives the mixing plate 306 to rotate, which stirs the nutrient solution in the mixing box 303 in real time, ensuring that the various nutrients in the nutrient solution are evenly distributed, so that the rice plants can absorb balanced nutrition and avoid growth being affected by excessively high or low local nutrient concentrations.
[0043] Working Mode Two: The mixing box 303, bolted to the support bracket 401, is removed, and the mixing connector 305 is disconnected from the water inlet pipe 403, thus removing the mixing section 3 from the device. The water inlet pipe 403 is then directly connected to the nutrient solution supply pipe. The operator places the device in the paddy field and turns on the power motor 204. The rotation of the power motor 204 drives the second power gear 205, which in turn drives the first power gear 203. The rotation of the first power gear 203 drives the power transmission column 202 and the power spray pipe 201. As the power transmission column 202 and the power spray pipe 201 rotate, the nutrient solution in the nutrient solution supply pipe is evenly sprayed onto the rice from the rotating power spray pipe 201, providing uniform fertilization to the rice.
[0044] Simultaneously, the worm gear mounted on the rotating power transmission column 202 drives the transmission worm wheel 101 to rotate. The rotation of the transmission worm wheel 101 drives the first transmission link 102 to rotate. The rotation of the first transmission link 102, through the second transmission link 103, pulls the third transmission link 104 to swing. When the third transmission link 104 swings to the right, the transmission pawl 107 contacts the transmission wheel 108, and the transmission return spring 105 is stretched, causing the third transmission link 104 to move to the rightmost end. When the third transmission link 104 swings to the left to return to its original position, the transmission pawl 107 contacts the transmission wheel 108. When the transmission wheel 108 contacts, the transmission pawl 107 is restricted in position by the transmission blocking post 106 and cannot rotate. As the transmission connecting rod 104 swings, it drives the transmission pawl 107 to rotate the transmission wheel 108, thereby realizing the movement of the device. That is, while the device moves, nutrient solution is applied evenly to the rice. The steering motor 501 drives the steering output frame 502 to deflect the steering wheel 503, thereby controlling the direction of movement of the device. No manual operation is required, and nutrient solution is sprayed on the rice from all directions.
[0045] By employing these two working modes, different usage needs can be met, thus expanding the applicability of the device.
