Description

Technical Field

[0001] This utility model relates to the field of pest and disease control technology, and in particular to a pest and disease control device for agricultural technology promotion. Background Technology

[0002] Agriculture, a key industry of the national economy, relies on land as its core resource, cultivating plants and animals to produce food and industrial raw materials. However, crop diseases and pests, as major disasters in my country's agriculture, seriously threaten agricultural production due to their numerous types, far-reaching impacts, and tendency to erupt into widespread outbreaks. For example, frequent outbreaks of diseases and pests such as rice planthoppers, powdery mildew, corn borers, cotton bollworms, locusts, and wheat scab cause significant damage to crop yields and quality, thereby affecting the stable development of the national economy. Therefore, adopting control measures such as pesticide spraying to effectively control the spread and damage of diseases and pests has become one of the key measures to ensure the sustainable and healthy development of my country's agricultural production.

[0003] A search revealed a spraying device for agricultural pest and disease control, patent number "CN219396030U". The adjusting mechanism includes a mounting frame. The mounting frame is fixedly mounted on the top side of the pesticide storage tank. A second motor is fixedly mounted inside the mounting frame. A lead screw is fixedly mounted on the output shaft of the second motor. A movable plate is threaded onto the surface of the lead screw, and a sprayer is fixedly mounted on the bottom of the movable plate. Specifically, driving the second motor rotates the lead screw, allowing the movable plate and sprayer to move left and right, enabling spraying over a larger area. However, the lead screw is easily corroded by dust, mud, and other contaminants in complex farmland environments. Because the lead screw is a precision mechanical component, its threaded portion is relatively fragile. If impurities enter, it will accelerate wear between the lead screw and the nut, reducing transmission accuracy and efficiency. Furthermore, the height and angle of the sprayer are difficult to adjust when dealing with crops of different heights or changing growth stages. This leads to uneven spraying, with some areas either missed or over-sprayed, resulting in pesticide waste and environmental pollution.

[0004] In this regard, this application proposes a pest and disease control device for agricultural technology extension. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an agricultural technology promotion and pest control device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pest and disease control device for agricultural technology promotion includes a base plate, a rectangular cylinder fixedly connected to the upper end of the base plate, a sliding plate slidably connected inside the rectangular cylinder, a fixing mechanism for fixing the sliding plate installed on the rectangular cylinder, a mechanism box fixedly connected to the upper end of the sliding plate, a double-threaded rod rotatably connected to the inner wall of the mechanism box, two telescopic sleeves threadedly connected to the double-threaded rod, telescopic sleeves provided on opposite side walls of the telescopic sleeves, the end of the telescopic sleeve away from the nut being fixedly connected to the unthreaded position of the double-threaded rod, a guiding mechanism for guiding the nut installed inside the mechanism box, a spray box fixedly connected to the side wall of the nut, a spray pipe communicating with the lower end of the spray box, a water supply mechanism for supplying water to the spray box installed on the base plate, and a medicine tank fixedly connected to the upper end of the base plate.

[0008] Preferably, the upper end of the medicine box is threaded with a water filling cap, and the side wall of the medicine box is provided with a transparent window.

[0009] Preferably, a push handle is fixedly connected to the upper end of the base plate, and four omnidirectional wheels are provided at the lower end of the base plate.

[0010] Preferably, a motor is fixedly connected to the side wall of the mechanism box, and the output shaft of the motor is fixedly connected to a double-threaded rod.

[0011] Preferably, the fixing mechanism includes a knob and a screw, the screw being threaded onto the side wall of the rectangular tube and passing through the rotating rectangular tube, and the knob being fixedly installed at the end of the screw away from the rectangular tube.

[0012] Preferably, the guiding mechanism includes a slider, and a groove is provided on the inner wall of the bottom end of the mechanism box. One end of the slider is fixedly installed on the lower end of the nut, and the other end of the slider slides in the groove.

[0013] Preferably, the water delivery mechanism includes a water pump, two telescopic hoses and a water pipe. The water pump is located at the upper end of the base plate and is connected to the medicine tank. The water pipe is installed at the upper end of the water pump. One end of the telescopic hose is connected to the water pipe, and the other end of the telescopic hose is connected to an adjacent spray box.

[0014] This utility model has the following beneficial effects:

[0015] 1. The rotation of the double-threaded rod drives two nuts to move in opposite directions or in opposite directions, thereby moving the two spray boxes. The movement of the nuts causes the telescopic sleeves on both sides of the nuts to deform, effectively protecting the threaded portion of the double-threaded rod from dust, mud, and other impurities. The telescopic sleeves automatically adjust their length as the nuts move, ensuring that the threaded portion of the double-threaded rod is always covered, thus reducing the possibility of impurities entering and lowering the risk of thread wear and transmission failure.

[0016] 2. The height of the mechanism box can be adjusted by moving the sliding plate up and down, thereby adjusting the height of the spray box and spray nozzles. Rotating the knob drives the screw to fix the height of the sliding plate, better adapting to crops of different heights and ensuring accurate spraying. This avoids spraying pesticides into non-target areas, reducing pesticide waste and environmental pollution, while improving pest and disease control effectiveness. Attached Figure Description

[0024] like Figure 1-5As shown, an agricultural technology extension pest control device includes a base plate 1, a rectangular tube 7 fixedly connected to the upper end of the base plate 1, a sliding plate 9 slidably connected inside the rectangular tube 7, a fixing mechanism for fixing the sliding plate 9 installed on the rectangular tube 7, a mechanism box 10 fixedly connected to the upper end of the sliding plate 9, a double-threaded rod 18 rotatably connected to the inner wall of the mechanism box 10, two telescopic sleeves 19 threadedly connected to the double-threaded rod 18, telescopic sleeves 19 are provided on opposite side walls, the end of the telescopic sleeve 19 away from the nut 20 is fixedly connected to the unthreaded position of the double-threaded rod 18, a guide mechanism for guiding the nut 20 is installed inside the mechanism box 10, a spray box 11 is fixedly connected to the side wall of the nut 20, a spray pipe 14 is connected to the lower end of the spray box 11, a water supply mechanism for supplying water to the spray box 11 is installed on the base plate 1, and a medicine tank 4 is fixedly connected to the upper end of the base plate 1. During operation, the sliding plate 9 is first moved up and down according to the height of the crops to adjust the height of the mechanism box 10, spray box 11, and spray nozzle 14, accommodating crops of different heights. Then, the knob 8 is turned to fix the sliding plate 9 in the appropriate position via the screw 17, ensuring a stable spraying height. After starting the motor 12, the motor 12 drives the double-threaded rod 18 to rotate, causing the nut 20 to move in opposite directions or in opposite directions, thus adjusting the left and right position of the spray box 11 and expanding the spraying range. The telescopic sleeve 19 automatically adjusts its length as the nut 20 moves, effectively protecting the threaded part of the double-threaded rod 18, preventing impurities from corroding it, and ensuring smooth spraying operations.

[0025] like Figure 1 As shown, a water inlet cap 5 is threaded onto the upper end of the medicine tank 4, and a transparent window 6 is provided on the side wall of the medicine tank 4. Through this structure, the design of the water inlet cap 5 makes adding medicine more convenient, and the threaded connection ensures the airtightness of the medicine tank 4, preventing leakage. The transparent window 6 allows operators to observe the remaining amount of medicine in the tank in real time, ensuring timely replenishment and improving work efficiency.

[0026] like Figure 1 As shown, a push handle 2 is fixedly connected to the upper end of the base plate 1, and four casters 3 are provided at the lower end of the base plate 1. Through this structure, the combination of the push handle 2 and the casters 3 makes it easier to move the device in the field. The flexibility of the casters 3 adapts to different terrains, improving the applicability of the device. Furthermore, the casters 3 have a self-locking mechanism.

[0027] like Figure 1 and Figure 2 As shown, a motor 12 is fixedly connected to the side wall of the mechanism box 10, and the output shaft of the motor 12 is fixedly connected to the double-threaded rod 18. Through the above structure, the output shaft of the motor 12 is fixedly connected to the double-threaded rod 18, realizing the automated left and right movement of the spray box 11, reducing manual intervention and improving spraying efficiency.

[0028] like Figure 2As shown, the fixing mechanism includes a knob 8 and a screw 17. The screw 17 is threaded onto the side wall of the rectangular tube 7 and passes through the rotating rectangular tube 7. The knob 8 is fixedly installed at the end of the screw 17 away from the rectangular tube 7. Through the above structure, the combined design of the knob 8 and the screw 17 makes the height fixing operation of the slide plate 9 simple and intuitive, requiring no complicated tools and facilitating on-site operation.

[0029] like Figure 5 As shown, the guiding mechanism includes a slider 22. A groove 21 is provided on the inner wall of the bottom of the mechanism box 10. One end of the slider 22 is fixedly installed on the lower end of the nut 20, and the other end of the slider 22 slides in the groove 21. Through the above structure, the cooperation between the slider 22 and the groove 21 ensures that the nut 20 remains stable during movement, prevents deviation, and improves the straightness of the movement of the spray box 11.

[0030] like Figure 2 As shown, the water delivery mechanism includes a water pump 13, two telescopic hoses 15, and a water pipe 16. The water pump 13 is located on the upper end of the base plate 1 and is connected to the medicine tank 4. The water pipe 16 is installed on the upper end of the water pump 13. One end of the telescopic hose 15 is connected to the water pipe 16, and the other end of the telescopic hose 15 is connected to the adjacent spray box 11. Through the above structure, the combination of the water pump 13, telescopic hoses 15, and water pipe 16 ensures that the liquid medicine is efficiently delivered from the medicine tank 4 to the spray box 11, reducing pressure loss during the delivery process. The design of the telescopic hoses 15 adapts to the left and right movement of the spray box 11, ensuring that the delivery of liquid medicine is not affected when adjusting the spraying range, thus improving the flexibility of the device.

[0031] In this invention, the slide plate 9 is first adjusted according to the height of the crops. By moving the slide plate 9 up and down, the height of the mechanism box 10 is adjusted, which in turn adjusts the height of the spray box 11 and the spray nozzle 14 to accommodate crops of different heights. The knob 8 drives the screw 17 to rotate, fixing the slide plate 9 at the desired height to ensure the stability of the spraying height. Then, the motor 12 is started, which drives the double-ended threaded rod 18 to rotate, causing the nuts 20 to move in opposite directions or in opposite directions, thereby adjusting the left and right position of the spray box 11 and expanding the spraying range. The telescopic sleeve 19 automatically adjusts its length as the nuts 20 move, protecting the threaded part of the double-ended threaded rod 18 from corrosion by impurities.

[0032] The device is moved by push handle 2, and casters 3 provide flexible movement. The medicine tank 4 stores the pesticide solution, the water inlet cap 5 is used to add the solution, and the transparent window 6 allows for easy observation of the remaining solution. Water pump 13 draws pesticide solution from the medicine tank 4, delivers it through water pipe 16 and telescopic hose 15 to the spray box 11, and then sprays it onto the crops through spray pipes 14.
