Abstract
Description
Technical Field
[0001] This invention relates to the fields of agricultural machinery technology and agricultural technology promotion and application technology, and in particular to a pest and disease control device for agricultural technology promotion. Background Technology
[0002] Agricultural pests and diseases are one of the core factors affecting crop yield and quality. Currently, the mainstream methods of pest and disease control in agricultural production still have many shortcomings.
[0003] In practical applications, existing equipment for pest and disease control in the field largely relies on manual backpack sprayers. One person can only cover 3-5 acres per day. Furthermore, manual mixing of pesticides often results in uneven mixing and sedimentation, leading to large fluctuations in pesticide concentration and significant differences in control effectiveness. Additionally, the coverage area of manual spraying is limited by arm reach, with a single spray width of less than 1 meter, requiring repeated back-and-forth travel. This results in high labor intensity and extremely low efficiency, making it unsuitable for the large-scale planting scenarios promoted by modern agricultural technology. Currently, most small-scale plant protection equipment on the market is "single-function": some equipment only has a spraying function, requiring pre-mixing of pesticides externally, which easily leads to pesticide sedimentation during transportation; while some equipment integrates a mixing module, it requires an additional independent motor to drive the mixing, increasing energy consumption and procurement costs. Furthermore, the dispersed power system increases the equipment's size, making it difficult to navigate narrow crop rows, which is detrimental to practical application and operation. Summary of the Invention
[0004] One objective of this invention is to provide a pest and disease control device for agricultural technology promotion.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an agricultural technology promotion and pest control device, comprising a vehicle body: the interior of the vehicle body is provided with a stirring device, and the exterior of the vehicle body is provided with a swing structure and an automatic steering device;

[0013] Preferably, the two identification cameras have symmetrically distributed shooting angles, jointly covering the areas on both sides of the vehicle's direction of travel. One of the identification cameras has a built-in image recognition module that can collect features of crop pest and disease areas and transmit the collected data to the controller, which then synchronously adjusts the spraying range of the spray head.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] (1) This invention does not require an additional stirring motor. It directly utilizes the driving power of the drive wheel to stir, reducing equipment energy consumption by about 20%. The bidirectional counter-rotating stirring roller can prevent emulsifiable concentrates and suspensions from settling and stratifying. The mixing uniformity is increased by 25% compared to unidirectional stirring, ensuring that the concentration of pesticides in all parts of the crop is consistent after spraying, and the effectiveness of pest and disease control is increased by 15%. The 35° reciprocating spray head increases the coverage area of a single spray by 40% compared to a fixed spray head. In a 1-acre cornfield, the time taken is reduced from 20 minutes to 12 minutes, and the work efficiency is increased by 40%. The arc-shaped groove limit design ensures that the swing trajectory deviation of the spray head is ≤2°, and the missed spray rate in the edge area is reduced to below 5%, avoiding repeated operations.
[0016] (2) This invention replaces manual positioning and steering operations by recognizing the combination of camera and controller, reducing labor costs by about 60%; the precise spraying function saves 10% to 15% of pesticide usage, which not only reduces farmers' pesticide purchase costs, but also avoids farmland pollution caused by excessive pesticide application, which is in line with the promotion direction of green prevention and control in agriculture; the triangular anti-slip teeth of the drive wheel improve the grip on muddy ridges by 30%, preventing the vehicle from slipping; the buffer spring between the connecting beam and the connecting parts can buffer the bump amplitude of ≤5cm, protect the internal cone wheel, gear and other transmission components, and greatly extend the service life of the device; the overall width of the device is ≤1.2m, which is suitable for the passage between the ridges of most crops such as wheat and vegetables, and can be operated directly without adjusting the ridge spacing in the field.
[0017] (3) The integrated design of this invention reduces the equipment procurement cost by 30% compared to the combination of "independent mixer + manual sprayer", making it suitable for small farmers, agricultural cooperatives and other different entities to purchase; the mechanical transmission components have no complex and precision structure, and only simple tools are needed to complete maintenance in the field, making it suitable for grassroots operation and maintenance scenarios in agricultural technology promotion.

A swing rod 17 is provided on the outer side of the vehicle body 1 and below the turntable 15. A groove is provided on the outer side of the swing rod 17. The slider 16 is used in conjunction with the groove. A spray head 19 is installed and connected to the bottom of the swing rod 17.
[0031] The bottom of the vehicle body 1 is provided with a connecting beam 20, and both ends of the connecting beam 20 are provided with connecting parts 21. The outer side of each connecting part 21 is provided with a drive wheel 23, and a steering shaft 24 is provided between the connecting parts 21.
[0032] The partition 4 has a linkage groove 5 inside, and two gears 6 are installed and connected inside the linkage groove 5. The gears 6 mesh with each other, and the stirring rods 3 are fixedly connected to the corresponding gears 6.
[0033] Inside the vehicle body 1 and on one side of the partition 4, there is a controller 25. The output end of the controller 25 is connected to the steering shaft 24.

[0036] Working principle:
[0037] During use, as material is fed from the hopper 2 and the vehicle body 1 moves forward, the drive wheel 14 drives the drive shaft 12 to rotate. The fourth cone wheel 13 on the outer side of the drive shaft 12 meshes with the third cone wheel 10 at the bottom of the rotating rod 7, causing the rotating rod 7 to rotate synchronously. The first cone wheel 8 at the top of the rotating rod 7 with 15 teeth meshes with the second cone wheel 9 on the outer side of one of the stirring rollers 3 with 30 teeth, causing the stirring roller 3 to rotate clockwise. Because the two gears 6 in the linkage groove 5 of the partition plate 4 mesh with each other, the other stirring roller 3 will rotate counterclockwise synchronously, ultimately achieving bidirectional shearing and stirring of the material, so that the mixing uniformity of the agent and the carrier reaches more than 95%. The drive device inside the vehicle body 1 drives the turntable 15 to rotate. The slider 16 on the edge of the turntable 15 is embedded in the groove of the swing rod 17, converting the circular motion of the turntable into the linear reciprocating thrust of the swing rod. At the same time, one end of the swing rod 17 slides along the arc groove 18 to precisely limit the swing trajectory. Every time the turntable completes one revolution, The swing lever 17 drives the spray head 19 to complete one reciprocating motion of "swinging 17.5° to the left → resetting → swinging 17.5° to the right → resetting", expanding the spray coverage width to 1.5 times the width of the vehicle body 1. The two recognition cameras 26 on the top of the vehicle body 1 are symmetrically distributed with a 60° field of view, jointly covering the crop area of 120° in the direction of travel. Its built-in image recognition module collects 20 frames of crop images per second, which can identify features such as lesions and insect clusters, with an accuracy rate of over 92%. After the collected feature data is transmitted to the controller 25 in real time, the controller completes two-step command output within 0.5 seconds: controlling the steering shaft 24 to move, driving the drive wheel 23 through the connector 21 to achieve a ±15° steering angle adjustment, so that the vehicle body 1 automatically corrects the travel path and aims at the concentrated area of pests and diseases; and simultaneously adjusting the opening of the solenoid valve of the spray head 19 to adjust the spray range from the basic 20cm to 30-50cm, ensuring that the agent accurately covers the target area.
