Description

Technical Field

[0001] This invention relates to the field of agricultural implements technology, and in particular to pesticide application devices for agricultural land. Background Technology

[0002] In modern agricultural production, the precise application of pesticides, fertilizers and other agents is crucial to ensuring crop yield and quality. With the development of large-scale and modern agriculture, the traditional manual application method has gradually revealed many drawbacks. Manual application is not only inefficient and unable to meet the needs of large-scale farmland operations, but also labor-intensive, placing a heavy burden on farmers. At the same time, the arbitrariness of manual operation is relatively large, which can easily lead to inaccurate pesticide ratios, affecting agricultural production results and even potentially causing damage to crops and the environment.

[0003] To address these issues, various automatic pesticide dosing devices have gradually emerged in the market. These devices achieve quantitative addition of pesticides through automation technology, improving dosing efficiency and accuracy to some extent. However, existing automatic pesticide dosing devices still have significant shortcomings. In terms of pesticide replenishment, most devices cannot achieve automatic monitoring and timely replenishment. When the pesticide solution in the tank is depleted, farmers often need to manually add pesticides and water. This not only delays the farming season but may also affect subsequent operations if the replenishment is forgotten. Moreover, the newly added pesticides and water are difficult to mix quickly and evenly in the tank. Traditional devices lack an effective automatic stirring mechanism, which cannot ensure the consistency of pesticide concentration, thus affecting the dosing effect.

[0004] In addition, existing pesticide dosing devices generally lack comprehensive alarm functions. Farmers find it difficult to monitor the remaining amount of pesticide in the tank in real time during busy farming activities. If there is no timely reminder when the pesticide in the tank runs out, the dosing will be interrupted, affecting the normal growth of crops. Even if some devices have alarm functions, they cannot accurately control the start and stop of the alarm, and the continuous noise will disturb the lives of nearby residents.

[0005] Based on the above situation, there is an urgent need for a pesticide application device that can flexibly apply pesticides and provide timely reminders, so as to improve pesticide application efficiency and reduce the workload of farmers. Utility Model Content

[0006] This utility model proposes a pesticide application device for agricultural land to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural land pesticide application device, comprising a pesticide tank, a tank cover fixedly installed at the upper end of the pesticide tank, a metering pump fixedly installed at the upper end of the tank cover, a pesticide outlet pipe fixedly connected to the upper surface of the metering pump, a pesticide inlet pipe fixedly connected to the lower surface of the metering pump, a filter element fixedly installed at the lower end of the pesticide inlet pipe, and an automatic pesticide application device, an automatic water application device, an automatic stirring device, and a pesticide application alarm device provided in the inner cavity of the pesticide tank.

[0008] Preferably, the automatic dosing device includes a medicine box, a lid hinged to the upper surface of the medicine box, a bottom hinged to the lower surface of the medicine box, a first connecting rope fixedly connected to the upper surface of the bottom of the medicine box, a counterweight fixedly connected to the lower end of the first connecting rope, a second connecting rope fixedly connected to the lower surface of the bottom of the medicine box, a float fixedly connected to the lower end of the second connecting rope, and a ball-fixing ring fixedly installed on the inner surface of the bottom of the medicine container, with the float disposed inside the ball-fixing ring.

[0009] Preferably, the automatic water filling device includes a third connecting rope, the lower end of which is fixedly connected to a switch, a solenoid valve is fixedly installed on the outer surface of the medicine tank, and a water inlet pipe is fixedly installed on the lower surface of the solenoid valve, the water inlet pipe extending into the inner cavity of the medicine tank.

[0010] Preferably, the upper end of the third connecting rope is fixedly installed on the outer surface of the float, the switch is fixedly installed on the inner surface of the bottom of the medicine container, and an electric wire is fixedly installed between the switch and the solenoid valve.

[0011] Preferably, the automatic stirring device includes two symmetrically arranged stirring paddles, and the two stirring paddles are fixedly installed with the same connecting shaft, and the outer surface of the connecting shaft is fitted with two symmetrically arranged support plates.

[0012] Preferably, the stirring paddle located below the water inlet pipe corresponds to the water outlet of the water inlet pipe, the connecting shaft and the support plate are rotatably connected, the lower surface of the support plate is fixedly connected to the inner surface of the bottom of the medicine tank, and the stirring paddle is located above the filter element.

[0013] Preferably, the dosing alarm device includes a buzzer, which is fixedly installed on the outer surface of the medicine tank. A wire is fixedly installed between the buzzer and the switch. The switch, solenoid valve and buzzer are all electrically connected to an external power source through the wire.

[0014] The agricultural pesticide application device provided by this utility model has the following improvements and advantages compared with the prior art:

[0015] Firstly, this utility model is equipped with an automatic dosing device, an automatic water inlet device, and an automatic stirring device. When the medicine liquid in the medicine tank is exhausted, the float ball pulls open the bottom of the medicine box filled with medicine, allowing the medicine to enter the medicine tank. At the same time, it presses the switch, forming a closed circuit, opening the solenoid valve, and allowing water to flow into the medicine tank through the water inlet pipe. Simultaneously, the water flows vertically down and impacts the stirring paddle, stirring and mixing the medicine in the medicine tank. This not only replenishes the medicine liquid in a timely manner but also greatly reduces the workload of farmers.

[0016] Secondly, this utility model is equipped with a dosing alarm device. When the liquid medicine in the medicine tank is almost exhausted, the float presses down and closes the switch, and the buzzer starts to sound, reminding farmers to replenish the medicine in time. When the liquid medicine in the medicine tank is full, the float rises and pulls the switch, and the buzzer stops working, keeping the tank quiet and avoiding noise that may affect the lives of nearby residents.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides an improved agricultural pesticide application device. The technical solution of this utility model is as follows:

[0025] like Figure 1 - Figure 3 As shown, the agricultural land pesticide application device includes a pesticide tank 1, a tank cover 2 fixedly installed on the upper end of the pesticide tank 1, a metering pump 3 fixedly installed on the upper end of the tank cover 2, a pesticide outlet pipe 4 fixedly connected to the upper surface of the metering pump 3, a pesticide inlet pipe 5 fixedly connected to the lower surface of the metering pump 3, a filter element 6 fixedly installed at the lower end of the pesticide inlet pipe 5, and an automatic pesticide application device, an automatic water application device, an automatic stirring device, and a pesticide application alarm device are provided in the inner cavity of the pesticide tank 1.

[0026] Furthermore, the automatic dosing device includes a medicine box 7, with a lid 8 hinged to the upper surface of the medicine box 7 and a bottom 9 hinged to the lower surface of the medicine box 7. A first connecting rope 10 is fixedly connected to the upper surface of the bottom 9, and a counterweight 11 is fixedly connected to the lower end of the first connecting rope 10. A second connecting rope 12 is fixedly connected to the lower surface of the bottom 9, and a float 13 is fixedly connected to the lower end of the second connecting rope 12. A ball-fixing ring 14 is fixedly installed on the inner bottom surface of the medicine container 1, and the float 13 is disposed inside the ball-fixing ring 14. When the float 13 descends to the bottom of the medicine container 1 as the medicine in the medicine container 1 decreases, the float 13 pulls the second connecting rope 12, thereby opening the bottom 9 and allowing the medicine in the medicine box 7 to enter the medicine container 1.

[0027] Furthermore, the automatic water filling device includes a third connecting rope 15, the lower end of which is fixedly connected to a switch 16. A solenoid valve 17 is fixedly installed on the outer surface of the medicine tank 1, and a water inlet pipe 18 is fixedly installed on the lower surface of the solenoid valve 17. The water inlet pipe 18 extends into the inner cavity of the medicine tank 1. When the float ball 13 descends to the bottom of the medicine tank 1 as the liquid decreases, the float ball 13 presses the switch 16, thereby closing the switch 16.

[0028] Furthermore, the upper end of the third connecting rope 15 is fixedly installed on the outer surface of the float 13, and the switch 16 is fixedly installed on the bottom inner surface of the medicine tank 1. A wire 23 is fixedly installed between the switch 16 and the solenoid valve 17. When the switch 16 is closed, a closed circuit is formed, the solenoid valve 17 is opened, and then the water flows into the medicine tank 1 through the water inlet pipe 18.

[0029] Furthermore, the automatic stirring device includes two symmetrically arranged stirring paddles 19, with a common connecting shaft 20 fixedly installed between the two stirring paddles 19. Two symmetrically arranged support plates 21 are sleeved on the outer surface of the connecting shaft 20. When the stirring paddle 19 located directly below the water inlet pipe 18 rotates, it can drive the other stirring paddle 19, which is away from the water inlet pipe 18, to rotate synchronously through the connecting shaft 20.

[0030] Furthermore, the stirring paddle 19 located below the water inlet pipe 18 corresponds to the water outlet of the water inlet pipe 18. The connecting shaft 20 and the support plate 21 are rotatably connected. The lower surface of the support plate 21 is fixedly connected to the inner surface of the bottom of the medicine tank 1. The stirring paddle 19 is located above the filter element 6. When water flows into the medicine tank 1 through the water inlet pipe 18, the impact force of the water falling vertically drives the stirring paddle 19 to rotate. Thus, the stirring paddle 19 can stir and mix the medicine in the medicine tank 1 by rotating.

[0031] Furthermore, the pesticide addition alarm device includes a buzzer 22, which is fixedly installed on the outer surface of the pesticide tank 1. A wire 23 is fixedly installed between the buzzer 22 and the switch 16. The switch 16, the solenoid valve 17, and the buzzer 22 are all electrically connected to an external power source through the wire 23. When the switch 16 is closed to form a closed circuit, the buzzer 22 will sound, thereby reminding the farmer to add pesticide.

[0032] Working Principle: When using this device, turn off the power switch, pour the mixed medicine into medicine container 1, the float 13 rises to its highest position, pull the switch 16, lower the counterweight 11 to ensure the bottom of medicine box 7 is closed, then pour the same dosage and type of medicine into medicine box 7, close the box lid 8, close the container lid 2, and turn on the power switch. As the medicine in medicine container 1 is continuously pumped out and consumed by the metering pump 3, the float 13 descends to the bottom of medicine container 1 as the medicine decreases. The float 13, on the one hand, pulls open the bottom 9 of the box through the second connecting rope 12, allowing the medicine in medicine box 7 to enter medicine container 1; on the other hand, the weight of the float 13 presses the switch 16, causing the switch 16 to close, thus closing the circuit. When the circuit is closed, the solenoid valve 17 opens, and water flows into the medicine tank 1 through the inlet pipe 18. The downward water flow impacts the medicine in the medicine tank 1 while driving the stirring paddle 19 to rotate. The rotating stirring paddle 19 evenly stirs the medicine in the medicine tank 1. At the same time as the switch 16 closes, the buzzer 22 starts to work and sounds to remind the farmer to replenish the medicine in time. When the medicine liquid in the medicine tank 1 returns to the highest water level, the float 13 rises to the highest position with the medicine liquid. At this time, the float 13 opens the switch 16 through the third connecting rope 15, the circuit is broken, the solenoid valve 17 closes, the buzzer 22 stops sounding, and the bottom 9 of the medicine box 7 closes again under the pull of the counterweight 11.

[0033] The foregoing description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
