Description

Technical Field

[0001] This utility model relates to the field of irrigation technology for seedling cultivation, and in particular to a precision irrigation and fertilization machine suitable for seedling cultivation. Background Technology

[0002] In agricultural planting, the planting area is usually carefully divided into multiple planting zones to more effectively manage and cultivate crops. During this process, seedlings need timely irrigation and fertilization at each stage of growth to ensure that they can obtain sufficient water and nutrients to grow healthily and robustly. Therefore, the application of irrigation and fertilization machines is particularly important. They not only improve the efficiency of fertilization and irrigation but also accurately meet the needs of crops, thus contributing to the sustainable development of agricultural production.

[0003] However, during spraying, fertilizer inside the mixing tank is prone to sedimentation, affecting the effectiveness of subsequent irrigation. Furthermore, traditional spraying methods have limitations in controlling fertilizer application, often failing to achieve precise delivery. This can result in insufficient application, hindering crop growth, or excessive application, leading to resource waste. This not only impacts fertilization effectiveness but also increases the difficulty of farmland management. Therefore, there is an urgent need for a precision irrigation and fertilization machine suitable for seedling cultivation to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precision irrigation and fertilization machine suitable for seedling cultivation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision irrigation and fertilization machine suitable for seedling cultivation includes a base, a fertilizer mixing tank is fixed to one top end of the base, a stirring mechanism to prevent fertilizer sedimentation is provided at the bottom of the fertilizer mixing tank, and a control mechanism to control the amount of fertilizer sprayed is provided at the other top end of the base.

[0007] The stirring mechanism includes a first rotating rod rotatably connected to the top and bottom of the inner wall of the fertilizer mixing tank. Multiple first stirring rods are fixed to the top of the outer wall of the first rotating rod. A waterproof box is provided at the bottom of the outer wall of the first rotating rod, with holes at the top and bottom of the waterproof box for the first rotating rods to pass through. Sealing rings are provided on the inner walls of the holes. A first bevel gear is fixed to the bottom of the outer wall of the first rotating rod. Second rotating rods are rotatably connected to both ends of the inner wall of the waterproof box, and the other ends of the two second rotating rods are rotatably connected to the inner wall of the fertilizer mixing tank. Second bevel gears are fixed to the sides of the two second rotating rods that are close to each other, and the two second bevel gears mesh with the first bevel gears respectively. Both the first and second bevel gears are located inside the waterproof box. Multiple second stirring rods are fixed to the outer walls of the two second rotating rods. The rotation of the second bevel gears drives the second rotating rods to rotate, which in turn drives the second stirring rods to rotate, thus stirring the bottom of the inner wall of the fertilizer mixing tank and preventing fertilizer sedimentation.

[0008] Preferably, support rods are fixed on both sides of the waterproof box, and the other ends of the two support rods are respectively fixed to the inner wall of the fertilizer mixing tank.

[0009] Preferably, a motor is installed on the top of the fertilizer mixing tank, the output shaft of the motor is fixedly connected to the top of the first rotating rod, and two feed ports communicating with the interior are provided at both ends of the top of the fertilizer mixing tank.

[0010] Preferably, a water pump is installed on the other side of the top of the base. The water inlet of the water pump is connected to and communicates with the bottom of the fertilizer mixing tank through a conduit. The water outlet of the water pump is connected to a delivery pipe. A water outlet pipe is fixed at one bottom end of the base. Several nozzles communicating with the bottom of the water outlet pipe are provided therewith. The other end of the delivery pipe is connected to and communicates with the top of the water outlet pipe.

[0011] Preferably, the control mechanism includes a hole that communicates with one end of the top of the base. A mounting bracket is fixed to one end of the top of the base and is located above the hole. An electric telescopic rod is mounted on the top of the mounting bracket. A mounting plate is fixed to the output shaft of the electric telescopic rod, and a humidity sensor is mounted on the bottom of the mounting plate. The humidity sensor can detect the humidity of the soil and transmit the signal to the controller. Then, the controller controls the pumping volume of the water pump to irrigate the soil.

[0012] Preferably, the base has two fixing plates fixed to both sides of one bottom end, and the two fixing plates are located on both sides of the hole. The two fixing plates are slidably provided with slide rods on their adjacent sides, and slots for the slide rods to pass through are opened on both sides of the two fixing plates. The two slide rods are fixed with mounting plates on their adjacent sides, and cleaning brushes are installed on the adjacent sides of the two mounting plates. One end of a spring is fixed to the opposite side of the two mounting plates, and the other end of the spring is fixedly connected to one side of the outer wall of the fixing plate. The spring can keep the cleaning brush close to the outer wall of the humidity sensor at all times, thereby increasing the cleaning effect.

[0013] Preferably, the base is equipped with casters at the four corners of its bottom.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the use of a stirring mechanism, when the first rotating rod rotates, it will drive the first bevel gear to rotate, and drive the two second bevel gears to rotate. The second rotating rod will drive the second stirring rod to rotate, and stir the fertilizer liquid at the bottom of the fertilizer mixing tank. This achieves the effect of preventing the fertilizer liquid from settling inside the fertilizer mixing tank, thereby improving the utilization efficiency of fertilizer, extending the storage time of fertilizer, and reducing waste.

[0016] 2. Thanks to the control mechanism, the humidity sensor can monitor the soil moisture, and then the controller controls the water pump to achieve precise control of the sprayed fertilizer water. Two cleaning brushes clean the surface of the humidity sensor, making the humidity sensor more accurate when monitoring in other locations, ensuring that the soil receives the appropriate amount of nutrients, realizing precision agriculture, and improving agricultural production efficiency.

[0027] In this utility model, a motor 202 is installed on the top of the fertilizer mixing tank 2. The output shaft of the motor 202 is fixedly connected to the top of the first rotating rod 203. Two feed inlets 201 communicating with the inside are provided at both ends of the top of the fertilizer mixing tank 2.

[0028] In this utility model, a water pump 3 is installed on the side of the other end of the top of the base 1. The water inlet of the water pump 3 is connected to and communicates with the bottom of the fertilizer mixing tank 2 through a conduit. The water outlet of the water pump 3 is connected to a conveying pipe 301. A water outlet pipe 302 is fixed at one end of the bottom of the base 1. Several nozzles 303 are provided at the bottom of the water outlet pipe 302 and communicate with it. The other end of the conveying pipe 301 is connected to and communicates with the top of the water outlet pipe 302.

[0029] In this utility model, the control mechanism includes a hole that is opened at one end of the top of the base 1. A mounting bracket is fixed at one end of the top of the base 1 and is located above the hole. An electric telescopic rod 4 is installed on the top of the mounting bracket. An installation plate is fixed to the output shaft of the electric telescopic rod 4. A humidity sensor 402 is installed at the bottom of the installation plate. The humidity sensor 402 can detect the humidity of the soil and transmit the signal to the controller. Then, the controller controls the pumping volume of the water pump 3 to irrigate the soil.

[0030] In this utility model, two fixing plates 401 are fixed on both sides of the bottom end of the base 1, and the two fixing plates 401 are located on both sides of the hole. The side of the two fixing plates 401 that is close to each other is slidably provided with a sliding rod 404, and the two fixing plates 401 have slots on both sides for the sliding rod 404 to pass through. The side of the two sliding rods 404 that is close to each other is fixed with a mounting plate 403. The side of the two mounting plates 403 that is close to each other is installed with a cleaning brush 405. The cleaning brush 405 can clean the surface of the humidity sensor 402. The side of the two mounting plates 403 that is far from each other is fixed with one end of a spring 406. The other end of the spring 406 is fixedly connected to one side of the outer wall of the fixing plate 401. The spring 406 can keep the cleaning brush 405 close to the outer wall of the humidity sensor 402 at all times, thereby increasing the cleaning effect.

[0031] In this utility model, universal wheels 101 are installed at the four corners of the bottom of the base 1.

[0032] Working Principle: In use, water and fertilizer are first added to the fertilizer mixing tank 2 through the two inlets 201. Then, the motor 202 is activated, driving the first rotating rod 203 to rotate. The first rotating rod 203 then drives the first stirring rod 204 to rotate, mixing the fertilizer inside the mixing tank 2. The rotation of the first rotating rod 203 also drives the first bevel gear 208 to rotate, which meshes with two second bevel gears 209, causing them to rotate. The two second bevel gears 209 then drive the second rotating rod 206 to rotate, which in turn drives the second stirring rod 207 to rotate, stirring the fertilizer solution at the bottom of the mixing tank 2 to prevent fertilizer sedimentation. The base 1 is then moved using the casters 101. When the base 1 reaches the area requiring irrigation, the controller activates the electric telescopic rod 4, which in turn activates the humidity sensor. 402 moves down, allowing the humidity sensor 402 to be inserted into the soil. The humidity sensor 402 then monitors the humidity inside the soil, and the monitoring result is transmitted to the controller. The controller processes the signal and then runs the water pump 3. Based on the signal transmitted by the humidity sensor 402, the water pump 3 extracts fertilizer from the fertilizer mixing tank 2 and sprays it out through the delivery pipe 301, the water outlet pipe 302, and the nozzle 303 to irrigate the soil. When the soil humidity changes to a suitable level, the controller shuts off the water pump 3, thus achieving precise irrigation of the soil. Then, the electric telescopic rod 4 retracts the humidity sensor 402. At this time, the spring 406 presses the mounting plate 403 and the cleaning brush 405, causing the two cleaning brushes 405 to adhere to the outer wall of the humidity sensor 402 and clean the outer wall of the humidity sensor 402 to prevent it from affecting the next monitoring.
