Description

A tracked pneumatic plant protection machine for mountainous wastelands Technical Field

[0001] This utility model relates to the field of plant protection machinery technology, specifically a tracked wind-driven plant protection machine for mountainous wastelands. Background Technology

[0002] Goji berries, an important economic crop with both medicinal and edible uses in my country, are increasingly being cultivated on uncultivated land, particularly hillsides in Northwest and North China, due to the increasing scarcity of land resources. These uncultivated lands have poor soil conditions, with a surface mostly composed of sand and gravel, loose texture, and steep slopes. Traditional wheeled tractors have significant drawbacks when operating on such terrain: firstly, insufficient tire traction leads to slippage, reducing power transmission efficiency and fuel economy; secondly, poor stability, especially on slopes, makes them prone to skidding or even tipping over, posing safety hazards; and thirdly, insufficient ground clearance makes them unsuitable for rugged, gravelly surfaces, severely impacting the continuity and effectiveness of plant protection operations.

[0003] Currently, goji berry plant protection operations mainly rely on towed or self-propelled boom sprayers, whose power systems are mostly matched with wheeled tractors. However, such equipment exposes the following technical bottlenecks when operating on undeveloped land:

[0004] Insufficient adaptability of the walking mechanism: The wheeled chassis has high ground pressure, making it easy to sink into soft sand, and it causes serious damage to the ground surface when turning, exacerbating soil erosion.

[0005] Limitations of wind-assisted spraying technology: Existing wind-assisted sprayers mostly use fixed guide vanes or a single air supply mode, which is difficult to adapt to the three-dimensional canopy structure of wolfberry plants, resulting in poor droplet penetration and uneven distribution. In particular, the lower and middle leaves of wolfberry plants planted on slopes are not adequately covered, which affects the control of diseases and pests.

[0006] Therefore, how to provide a tracked, wind-powered plant protection machine for mountainous and barren land has become an urgent technical problem to be solved in this field. Summary of the Invention

The guide plate is mounted on the side of the tracked chassis away from the operating platform, and the air-assisted spray assembly is mounted at the center of the guide plate. Multiple nozzles are arranged on the guide plate and surround the air-assisted spray assembly.

[0009] Furthermore, the air-driven spray assembly includes a drive shaft, a gearbox, a drive belt, a pulley, a bearing housing, a drive rod, and a fan; one end of the drive shaft is connected to the power output shaft of the engine, and the other end is connected to the input end of the gearbox; the output end of the gearbox is connected to the pulley via the drive belt; the pulley is mounted on a frame connected to a tracked chassis via a bearing housing; one end of the drive rod is connected to the pulley, and the other end is connected to the fan.

[0010] Furthermore, the tracked chassis includes support wheels, tracks, drive wheels, and chassis brackets; multiple support wheels and drive wheels are mounted on the chassis brackets, and the tracks are fitted onto the support wheels and drive wheels.

[0011] Furthermore, the control panel is equipped with a driver's seat, an engine, and control levers.

[0012] The beneficial effects of this utility model are as follows:

[0025] As shown in Figures 1-2, this utility model provides a tracked, air-assisted plant protection machine for barren land to assist in plant protection operations. Based on the planting patterns and power requirements of barren land, research was conducted on tracked chassis and power matching, air-assisted spraying, and other technologies, focusing on solving problems related to the corresponding power matching of tracked walking and air-assisted spraying range. It includes: a tracked chassis 1, an operating platform 2, a pesticide tank 3, and a spraying device. The operating platform 2 and the pesticide tank 3 are both mounted on the tracked chassis 1, with the pesticide tank 3 located on one side of the operating platform 2. The pesticide tank 3 is connected to the spraying device via a pesticide delivery pipe 4 and is used to store pesticide solution. The spraying device includes a guide plate 5, nozzles 6, a pesticide pump 7, and an air-assisted spraying assembly 8.

Multiple nozzles 6 are arranged on the guide plate 5 and surround the air-assisted spraying assembly 8.

[0026] Referring to Figure 3, the air-assisted spray assembly 8 includes a drive shaft 9, a gearbox 10, a drive belt 11, a pulley 12, a bearing housing 13, a drive rod 14, and a fan 15. One end of the drive shaft 9 is connected to the power output shaft of the engine, and the other end is connected to the input end of the gearbox 10. The output end of the gearbox 10 is connected to the pulley 12 via the drive belt 11. The pulley 12 is mounted on a frame connected to a tracked chassis via the bearing housing 13. One end of the drive rod 14 is connected to the pulley 12, and the other end is connected to the fan 15.
