Description

Technical Field

[0001] This utility model relates to a grain pile pesticide application device, and more specifically, to a grain pile intelligent pesticide application device that automatically controls the dosage of pesticides. Background Technology

[0002] Food is of paramount importance to our populous nation. Ensuring the basic needs of people for food, clothing, shelter, and transportation hinges on the safe storage of grain. During storage, pest infestations are inevitable, affecting grain quality and causing unnecessary losses. This necessitates the application of pesticides inside the grain pile by warehouse personnel. However, applying pesticides inside the pile makes it impossible to determine the dosage. Previously, warehouse personnel relied on personal experience to control the dosage, which could lead to two problems: either too little pesticide, leaving some pests unkilled, or too much pesticide, resulting in waste. To avoid these issues and improve the cost-effectiveness of pest control, this invention proposes an intelligent pesticide application device for grain piles. Summary of the Invention

[0052] The present invention will now be described in detail with reference to the accompanying drawings:

[0053] See Figures 1 to 3 The intelligent pesticide application device for grain piles includes an electric part and a mechanical part.

[0054] The electric components include a power bank 11, a touch screen 12, a main control board 13, control buttons 14, a flow meter 15, a solenoid valve 16, and a booster pump 17.

[0055] The electric component can input the desired dosage of the medicine and intelligently control the medicine to be output according to the desired value;

[0056] The mechanical parts include a water storage tank 21, a baffle 22, a frame 23, a four-way nozzle 24, a spray bar 25, a handle shell 26, and a handle 27;

[0057] The mechanical part is used to fix and install the electric part and store the medicine, and the electric part is mounted on the mechanical part.

[0058] The mobile power supply 11 provides the necessary power to the touch screen 12, main control board 13, control button 14, flow meter 15, solenoid valve 16 and booster pump 17;

[0059] The touchscreen 12 is used by warehouse personnel to input the desired dosage of the sprayed agent;

[0060] The main control board 13 receives the desired value input from the touch screen 12. When it receives the switch signal from the control button 14, it controls the booster pump 17 and the solenoid valve 16 to spray the medicine. It also receives the cumulative value of the current outflowing medicine from the flow meter 15 and compares it with the desired value. When the cumulative value equals the desired value, it turns off the booster pump 17 and the solenoid valve 16 to stop the medicine from being sprayed.

[0061] When the control button 14 is pressed, the medicine begins to spray out;

[0062] The flow meter 15 measures the amount of medicine sprayed out.

[0063] The solenoid valve 16 controls the opening or closing of the agent spraying channel;

[0064] The booster pump 17 provides pressure for the spraying of the agent.

[0065] See Figure 4 The portable power supply 11 is a YOOSUN L1210A lithium-ion portable power supply. This power supply has short-circuit protection, overcharge protection, over-discharge protection, overcurrent protection, and temperature protection. In this embodiment, the operating current can reach 7A. The dimensions are 160mm*90mm*60mm, and the weight is 0.75kg, making it easy to carry. The portable power supply 11 has four connection pins. V1+ and V1- are the positive and negative pins of a 12V output power supply, respectively. V1+ is connected to pin 2 of the solenoid valve 16 and the red lead of the booster pump 17, respectively. The V1- pin is connected to one pin of the control button 14 and the pad hole VG of the main control board 13, respectively. V2+ and V2- are the positive and negative pins of a 5V output power supply, respectively. This 5V output power supply provides working power to the main control board 13, the flow meter 15, and the touch screen 12.

[0066] The touchscreen 12 is a DMG32240C028_03WTC model touchscreen. The touchscreen 12 has four connection pins, of which the Vcc pin is connected to the V2+ pin of the power bank 11, the Vss pin is connected to the V2- pin of the power bank 11, the TX pin is connected to the RX1 pad hole of the main control board 13, and the RX pin is connected to the TX1 pad hole of the main control board 13. The touchscreen 12 communicates with the main control board 13 via serial port. In this embodiment, the dimensions of the touchscreen 12 are 26.9mm (W) x 19.1mm (H) x 4.6mm (T). Positioning holes are provided at the four corners for installation. The touchscreen 12 is fixed to the connecting plate 222 by screws and nuts.

[0067] Working principle: The desired value of the spraying agent dosage can be set on the screen of the touch screen 12 as needed, and the desired value is transmitted to the main control board 13 through the serial port.

[0068] The control button 14 is a CZHOBO HBZ-12A-P10 self-resetting switch. In this embodiment, the control button 14 has an opening diameter of 16mm, which matches the uppermost opening diameter of the vertical baffle 221 of the baffle 22. The control button 14 is equipped with a nut to fix it to the vertical baffle 221. The control button 14 has two pins. One pin of the control button 14 is connected to the IN pad hole of the main control board 13. The other pin of the control button 14 is connected to the V1- pin of the power supply 11.

[0069] Working principle: When the control button 14 is pressed, the two pins of the control button 14 are turned on, and the IN pad hole of the main control board 13 is at a low level, triggering the spraying operation.

[0070] See Figure 5 and Figure 6 The flow meter 15 is a Hall effect water flow meter of model YF-S201. This water flow meter has a wide operating voltage range, small size, and is easy to install. The sealing ring adopts an upper and lower force-bearing structure to prevent water leakage. The flow meter 15 is provided with 3 pins, of which the + pin is connected to the V2+ of the mobile power supply 11, the - pin is connected to the V2- of the mobile power supply 11, and the OUT pin is connected to the solder pad hole FB of the main control board 13. The flow meter 15 is provided with a passage. This passage is a cylindrical shell with open front and rear ends and external threads at both ends. In this embodiment, the threads match the internal threads of a 4-point internal thread x 14mm pagoda connector. A pagoda connector is installed at the front end of the passage. The connector body of the pagoda connector is connected to a PV hose. The other end of the PV hose is connected to the handle of the spray bar 25 through another pagoda connector. A pagoda connector is also installed at the rear end of the passage. The connector body of the pagoda connector is connected to another PV hose. The other end of the other PV hose is connected to the solenoid valve 16 through another pagoda connector.

[0071] See Figure 6 The pagoda connector includes a hexagonal prism portion at the top and a connector body at the bottom.

[0072] The pagoda connector is a common pipe fitting. In all embodiments, the pagoda connectors mentioned are selected with 4-point (G1 / 2) internal threads and a diameter of 20mm. The center of the hexagonal prism at the top has a through hole with a thread inside. The bottom of the pagoda connector is the connector body, and the outer diameter of the connector body is smaller than the diameter of the hexagonal prism at the top. The connector body is formed by several identical trapezoidal rings connected vertically. The rotation axes of the trapezoidal rings are collinear and collinear with the rotation axis of the hexagonal prism. The internal thread hole of the hexagonal prism is connected to the through hole at the center of the connector body. Adjacent trapezoidal rings are connected by the smaller diameter end of the upper trapezoidal ring and the larger diameter end of the lower trapezoidal ring. The connector body is connected to the PVC pipe.

[0073] Working principle: When the medicine flows through the flow meter 15, a corresponding pulse signal is generated on the OUT pin and fed back to the main control board 13. The main control board 13 judges the cumulative value of the medicine flow and thus determines whether the expected value set by the touch screen 12 has been reached.

[0074] The solenoid valve 16 is a normally closed solenoid valve of model 2W160-15. This solenoid valve 16 has two pins, pin 1 and pin 2. Pin 1 is soldered to the pad hole CO1 on the main control board 13, and pin 2 is connected to the V1+ pin of the power supply 11. The solenoid valve 16 has a channel from P to A. Both ends of this channel are provided with external threads. These threads match the internal threads of the hexagonal prism part of the 4-point internal thread X14mm pagoda connector. Each of the P and A ends is connected to a 4-point internal thread X14mm pagoda connector. The connector body of the pagoda connector connected to the A end is connected to one end of a PV hose. The other end of the PV hose is connected to the flow meter 15 through the pagoda connector. The connector body of the pagoda connector connected to the P end is connected to another PV hose. The other end of the other PV hose is connected to the outlet of the booster pump 17 through the pagoda connector.

[0075] Working principle: When the voltage level on the pad hole CO1 of the main control board 13 is low, the solenoid valve 16 is energized, the channel from P to A is opened, and the agent can flow through the solenoid valve 16. Conversely, when the voltage level on the pad hole CO1 is high, the solenoid valve 16 does not work, and the agent cannot pass through the solenoid valve 16. After the booster pump 17 stops, the solenoid valve 16 must also stop working immediately. Otherwise, the residual agent in the hose will continue to be sprayed out after the booster pump 17 stops, causing the sprayed agent dosage to be greater than the expected value.

[0076] See Figure 7The booster pump 17 is a vacuum self-priming diaphragm booster pump of model SFL42-013-035-12. This pump features low noise, low power consumption, and high-efficiency boosting. The booster pump 17 has two leads, one red and one black. The red lead connects to the V1+ pin of the power supply 11, and the black lead connects to the CO2 pad hole on the main control board 13. The booster pump 17 has an inlet and an outlet. The inlet has an external thread that matches the internal thread of the hexagonal prism portion of a 4-point internal thread x 14mm pagoda connector. A pagoda connector is installed on the inlet. The connector body of the pagoda connector connects to one end of the PV hose. The other end of the PV hose passes through the 16mm round hole in the middle of the vertical baffle 221 of the baffle 22 and connects to a pagoda connector with the same structure. The connector body of the head, the hexagonal prism part of this pagoda connector is connected to the water outlet of the water storage tank; the outlet of the booster pump 17 is provided with an external screw, and the thread is matched with the internal thread of the hexagonal prism part of the 4-point internal thread x 14mm pagoda connector. A pagoda connector is installed on the outlet, and the connector body of the pagoda connector is connected to the PV hose. The other end of the PV hose passes through the 16mm round hole at the bottom of the vertical baffle 221 of the baffle 22 and connects to the connector body of a pagoda connector with the same structure. The threaded part of this pagoda connector is installed on the P end of the solenoid valve 16; the base of the booster pump 17 is provided with 4 threaded posts with internal threads. The position of the threaded posts is aligned with the position of the mounting holes on the rear wall plate of the frame 23. The booster pump 17 is fixedly installed on the rear wall plate 232 of the frame 23 by matching screws.

[0077] Working principle: When the CO2 level on the pad hole is low, the built-in motor of the booster pump 17 starts to rotate, drawing the agent from the low-pressure area to the high-pressure area; conversely, when the CO2 level on the pad hole is high, the built-in motor of the booster pump 17 stops rotating.

[0078] See Figure 8The main control board 13 is a plate-shaped structural component. Mounting holes are provided at the four corners of the main control board 13. The dimensions of each pair of adjacent mounting holes are 60mm x 60mm, and the center line connecting the four mounting holes forms a square. The diameter of each mounting hole is 3mm. The position and dimensions of the mounting holes are aligned with the four small round holes on the middle wall panel of the frame 23. The main control board 13 is mounted on the left side wall of the middle wall panel 233 using screws and nuts. An MCU is located at the center of the main control board 13. U1 has nine pad holes between its two mounting holes. From left to right, these are pad holes VG, V+, V-, FB, TX1, RX1, IN, CO1, and CO2. Pad hole VG is connected to the V1- pin of the power supply 11. Pad hole V+ is connected to the V2+ pin of the power supply 11. Pad hole V- is connected to the V2- pin of the power supply 11.

[0079] See Figure 9 The MCU U1 uses an STC8A8K32AS4A12 microcontroller, operating at 1.9V to 5.5V, and is economically priced. The VCC pin of the MCU U1 is connected to the V+ pad on the main control board 13; the VSS pin is connected to the V- pad on the main control board 13; the RX pin is connected to the RX1 pad; the TX pin is connected to the TX1 pad on the main control board 13; the IN1 pin is connected to the FB pad; and the IO pin is connected to the IN pad on the main control board 13. The OUT1 pin of U1 is connected to one pin of resistor R1, the other pin of R1 is connected to the B pin of transistor Q1, the E pin of transistor Q1 is connected to the pad hole VG on the main control board 13, and the C pin of transistor Q1 is connected to the pad hole CO1 on the main control board 13.

[0080] Working principle: When warehouse personnel want to kill insects, they need to input the desired dosage of pesticide on the touch screen 12. When the MCU U1 receives the desired dosage from the touch screen 12, it stores the desired value. When the warehouse personnel press the control button 14, the IN pad of the main control board 13 is at a low level. At this time, when the MCU U1 detects that the IO level is low, the OUT2 and OUT1 pins output a high level, the transistors Q1 and Q2 are turned on, and the CO1 and CO2 pads on the main control board 13 become low. The booster pump 17 is powered on, and the built-in motor starts to rotate, drawing the pesticide from the low-pressure area to the high-pressure area. When the solenoid valve 16 is powered on, the channel PA opens, the pesticide enters the spray bar 25, and is sprayed out from the four atomizing nozzles. The flow meter 15 starts to measure the dosage of the sprayed pesticide and feeds it back to the MCU U1. The MCU U1 compares the current cumulative value with the desired value. When the cumulative value reaches the desired value, the MCU... U1 controls the OUT2 and OUT1 pins to output a low level, which cuts off transistors Q2 and Q1, de-energizes solenoid valve 16 and booster pump 17, prevents the medicine from flowing out, and precisely controls the dosage of the medicine.
