Description

Technical Field

[0001] This utility model relates to an irrigation device for corn cultivation, specifically an irrigation device for corn cultivation, belonging to the field of corn technology. Background Technology

[0002] Corn requires significantly different depths and quantities of water at different growth stages. Seedlings need shallow irrigation to promote root development, while after the jointing stage, deep irrigation is required to cope with vigorous growth. Existing corn irrigation equipment has three major drawbacks:

[0003] Unable to intelligently perceive demand: Most equipment uses timed or experience-based irrigation, which cannot obtain real-time soil moisture data, resulting in irrigation decisions being out of touch with the actual needs of crops, leading to water waste or insufficient water supply.

[0004] Irrigation depth is not adjustable: The irrigation depth of equipment such as sprinkler irrigation and fixed drip irrigation is fixed and cannot be dynamically adjusted according to the changes in root depth of corn at different growth stages, resulting in low irrigation efficiency.

[0005] Unable to adapt to different row spacings: The row spacing of large sprinkler or drip irrigation systems is fixed during installation, making it unable to adapt to the row spacing requirements of different corn varieties and planting patterns, resulting in poor versatility. For breeding test fields, different varieties are planted in different zones with varying row spacings, making it difficult to apply fixed equipment.

[0006] Therefore, an irrigation device for corn cultivation is proposed here. Utility Model Content

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0032] Please see Figures 1 to 11 This utility model provides an irrigation device for corn cultivation, including a frame 1, an adjustable irrigation mechanism 2 is provided on the outside of the frame 1; the adjustable irrigation mechanism 2 includes a water storage tank 201, a controller body 204 is fixedly connected to the outer surface of the water storage tank 201, and a metering pump 210 is fixedly connected to the inner wall of the water storage tank 201.

[0033] The metering pump 210 mainly consists of a power drive unit, a transmission mechanism, a pump head actuator unit, a flow regulation mechanism, and a fluid channel. The power drive unit is typically an electric motor, providing power for the equipment's operation. The transmission mechanism, such as a cam or eccentric wheel, converts the motor's rotational motion into the reciprocating linear motion of a plunger or diaphragm. The pump head actuator unit, including the plunger / diaphragm, inlet check valve, and outlet check valve, is the core of the fluid delivery system. The flow regulation mechanism, such as a stroke adjustment knob and a speed controller, is used to precisely control the delivery volume. The fluid channel consists of an inlet, an outlet, and a pump chamber. Its working principle is as follows: the motor drives the transmission mechanism to operate... The driving plunger or diaphragm reciprocates within the pump chamber. When the plunger / diaphragm moves backward, the pump chamber volume increases, the internal pressure decreases, the inlet check valve opens, and the outlet check valve closes, allowing the fluid to be transported to be drawn into the pump chamber through the inlet. When the plunger / diaphragm moves forward, the pump chamber volume decreases, the pressure increases, the outlet check valve opens, and the inlet check valve closes, allowing the pressurized fluid to be discharged quantitatively from the outlet. By adjusting the reciprocating stroke of the plunger / diaphragm or the motor speed, the fluid delivery rate per unit time can be precisely controlled, enabling accurate metering and stable delivery of liquids such as pharmaceuticals, additives, and corrosive fluids.

[0034] The output end of the metering pump 210 is fixedly connected to a three-way pipe 211. Three telescopic hoses 209 are fixedly connected to the outer surface of the three-way pipe 211. A solenoid valve 212 is fixedly connected to the outer surface of each telescopic hose 209. A groove 207 is provided on the left side of the frame 1. A ball screw 206 is rotatably connected to the inner wall of the groove 207. Three sliders 208 are threaded onto the outer surface of the ball screw 206. A fixing bracket 217 is fixedly connected to the left side of each slider 208. A groove 218 is provided on the outer surface of each fixing bracket 217. Two electric push rods 215 and a telescopic rod 213 are fixedly connected to the outer surface of each fixing bracket 217. A loading plate 216 is fixedly connected to the telescopic end of each set of electric push rods 215. Each telescopic rod 213 has a soil temperature and humidity sensor 214 fixedly connected to its telescopic end. The soil temperature and humidity sensor 214 monitors changes in the soil environment by measuring the soil temperature and humidity. Its working principle is based on the temperature sensing element and humidity sensing element inside the sensor. The temperature sensor usually uses a thermocouple or thermistor to sense temperature changes; the humidity sensor uses changes in capacitance, resistance or conductivity to measure the moisture content in the soil. The sensor consists of a sensing element, a signal processing circuit and an output interface. The sensing element converts the sensed physical quantity into an electrical signal, and the signal processing circuit amplifies, filters and converts the electrical signal. Finally, the processed data is transmitted to the monitoring system or control equipment through the output interface.

[0035] A servo motor 205 is installed on the outer side of the frame 1. The power output end of the servo motor 205 is fixedly connected to the end of the ball screw 206 near the servo motor 205.

[0036] Please refer to this carefully. Figure 1 Each loading plate 216 has its outer surface slidably connected to the inside of the groove 218, and each telescopic hose 209 has its outer surface fixedly connected to the inner wall of the fixing frame 217. The outer surface of the water tank 201 is fixedly connected to the water outlet pipe 202, and the outer surface of the water outlet pipe 202 is fixedly connected to the valve 203. After watering is completed, excess water in the water tank 201 can be discharged through the water outlet pipe 202 and the valve 203. The outer surface of the controller body 204 is fixedly connected to the fixing frame 8, and the outer surface of the fixing frame 8 is fixedly connected to the outer surface of the water tank 201. The fixing frame 8 can be used to fix and protect the controller body 204, and prevent the controller body 204 from shaking during use.

[0037] The controller consists of two parts: hardware and software. The hardware mainly includes a central processing unit (CPU) for computation, input / output (I / O) interfaces for connecting sensors and actuators, memory for storing programs and data, and power supply and communication modules. The software includes control algorithm programs, real-time operating systems (RTOS), and human-machine interfaces, all working together to ensure precise and efficient system control. It is widely used in industrial automation, smart homes, automotive electronics, and other fields. A controller is a core device that regulates system operation by processing input signals in real time and generating control commands. Its working principle can be summarized as follows: First, it collects signals from sensors or external inputs such as temperature and speed, compares them with preset target values ​​to calculate the deviation; then, it uses built-in algorithms such as PID control and logical judgment to analyze the deviation and generate adjustment commands; finally, it drives actuators such as motors through the output interface to adjust the system state, while continuously monitoring the effect through closed-loop feedback to achieve dynamic stability. The controller can control the electrical components of this technical solution.

[0038] Please refer to this carefully. Figure 1 The upper surface of the water storage tank 201 is movably hinged with a movable door 4, and the upper surface of the movable door 4 is fixedly connected with a handle 5. The movable door 4 and the handle 5 facilitate the staff to add water to the water storage tank 201 and observe the water level, thereby facilitating the operation of the staff.

[0039] Please refer to this carefully. Figure 1 Two pushers 6 are fixedly connected to the right side of the frame 1. Each pusher 6 has an anti-slip sleeve 7 fixedly connected to its outer surface. The pushers 6 and the anti-slip sleeves 7 work together to facilitate the movement of the device by the staff, thereby improving the working efficiency of the device.

[0040] Please refer to this carefully. Figure 4 Each electric push rod 215 has a fixed ring 9 fixedly connected to its outer surface. The bottom end of each fixed ring 9 is fixedly connected to the upper surface of the carrier plate 216. The fixed ring 9 can be used to fix the electric push rod 215 and prevent the electric push rod 215 from tilting during use.

[0041] Please refer to this carefully. Figure 1 An L-shaped plate 3 is fixedly connected to the outer surface of the servo motor 205. The outer surface of the L-shaped plate 3 is fixedly connected to the outer surface of the frame 1. The L-shaped plate 3 can be used to fix the servo motor 205 and prevent the servo motor 205 from shaking during use.

[0042] In use, the following steps are taken: First, connect the controller body 204, servo motor 205, metering pump 210, soil temperature and humidity sensor 214, electric push rod 215, and telescopic rod 213 to the power supply. When using this device to irrigate corn, the worker moves the device to the cornfield. Then, the worker adjusts the distance between two adjacent sliders 208 (i.e., the distance between two adjacent grooves 218) according to the corn row spacing. The controller body 204 controls the servo motor 205 to work, and the servo motor 205 works in the groove. Under the support of 207, the ball screw 206 is driven to rotate. Since the ball screw 206 and the slider 208 are threadedly connected, the rotation of the ball screw 206 drives the slider 208 to slide along the inside of the groove 207. The rotation of the ball screw 206 adjusts the distance between the two sliders 208. The sliding of the slider 208 drives the movement of the detection and irrigation structure composed of the fixed frame 217, telescopic hose 209, electric push rod 215, telescopic rod 213, soil temperature and humidity sensor 214, carrier plate 216 and groove 218.

[0043] When slider 208 is adjusted to the appropriate position, controller body 204 controls servo motor 205 to stop working. Then, the worker moves the frame 1 to the corn plant requiring irrigation. The controller body 204 then controls the telescopic rod 213 to extend and retract, causing the soil temperature and humidity sensor 214 to penetrate deeper into the soil. The soil temperature and humidity sensor 214 transmits the detected data to controller body 204. The worker then comprehensively assesses this data against the rated soil moisture data set by controller body 204 and the required irrigation depth and metering data for different growth stages of the corn. Controller body 204 determines the appropriate irrigation depth and water metering. Finally, the worker uses controller body 204 to open the solenoid valve 212 above the corn plant requiring irrigation. The solenoid valve 212 is closed, and the metering pump 210 is controlled by the controller body 204 to work according to the irrigation depth and irrigation water metering. Then, the electric push rod 215 is controlled to extend and retract. First, the extension and retraction of the electric push rod 215 drives the irrigation structure composed of the groove 218 and the carrier plate 216 to move downward along the groove 218. When the rigid stainless steel water pipe at the bottom of the groove 218 contacts the ground, the movement stops. The electric push rod 215 is controlled to move downward to a reasonable depth. Then, the solenoid valve 212 is controlled to open and the metering pump 210 is controlled to work. The operation of the metering pump 210 realizes precise irrigation of the corn plant. Through this device, the depth and amount of immersion irrigation can be precisely adjusted according to the growth stage of the corn plant, row spacing and soil moisture to achieve precise irrigation of the corn plant.
