Crawler-Type Fruit Tree Spraying Robot

This crawler-type fruit tree spraying robot chassis is specifically engineered for complex agricultural environments. Serving as the core load-bearing and mobility platform for the entire machine, it delivers high stability, precise steering, and exceptional adaptability to harsh conditions. Primarily deployed in orchards, botanical gardens, vegetable farms, and greenhouses, it excels at navigating challenging terrains such as 30° steep slopes, muddy surfaces, and narrow pathways—areas where conventional equipment struggles to operate.

Table Parameters

IP55 waterproof and dustproof certification, featuring dual-layer silicone seals + stainless steel cable channels throughout the unit:

The dustproof layer resists crystalline dust and pollen dispersed during pesticide spraying, preventing motor clogging; the waterproof layer withstands sudden downpours and daily high-pressure tank rinsing, ensuring the 48V electrical system operates continuously on muddy slopes.

In the greenhouse environment of botanical gardens, IP55 protection shields against high humidity (humidity >90%) and plant spore corrosion, preventing moisture-induced short circuits in precision controllers and ensuring accurate plant protection operations for precious species. On open-air ridges at vegetable farms, its splash resistance withstands irrigation system flooding and fertilizer washouts (corrosive liquids with pH 3-11). A 220mm ground clearance combined with a sealed design prevents mud from infiltrating the gearbox. Unlike ordinary robotic chassis equipment, it can directly withstand high-pressure spraying and fertilizer corrosion in orchards.

860KG Counterweight Chassis Design: Optimized center of gravity distribution through dynamic simulation, featuring 220mm of exceptional ground clearance to effortlessly traverse tree roots and rocks.

60mm high-strength track pitch: Custom rubber-steel composite tracks deliver ground pressure as low as 18 kPa (equivalent to an adult walking), preserving soil structure. After 500 hours of continuous operation on soft mud in strawberry greenhouses, the track wear rate remains below 3%, significantly outperforming wheeled equipment.

Dual-Drive Smart Controller: Exclusively supports CAN/PWM/232/485 quad-protocol interfaces, enabling seamless integration with greenhouse IoT systems within 10 minutes.

Precision speed control from 0-3 km/h: On a compact chassis measuring 1930×1230×1250 mm (L×W×H), the low-speed gear (0.5 km/h) enables precise spraying in high-density orchards, while the high-speed gear (3 km/h) facilitates rapid movement to open vegetable plots.

Zero-radius 360° turning on the spot: Dual-motor differential control technology achieves a turning radius of zero. Within vegetable greenhouses just 1.5 meters wide, it switches between rows without reversing, preventing damage to seedlings.

Modular Tank Interface: Features a quick-release slot for tanks ranging from 20L to 500L, compatible with insecticides, foliar fertilizers, and biological agents. Paired with a 220 mm off-ground spray boom, it achieves >92% droplet coverage (laser particle size analysis report) and reduces chemical usage by 28% compared to manual application.

Orchard: Slippery muddy terrain with slopes exceeding 25 degrees (e.g., waxberry slopes, citrus terraces), GPS signal loss due to overlapping tree canopies, pesticide crystallization corroding equipment—particularly during high-frequency spraying seasons, where acidic chemical residues erode circuit board solder joints.

Botanical Garden Challenges: The tropical greenhouse's high humidity (RH > 95%) easily disrupts visual navigation. The fragile root systems of mosses and ferns require equipment vibration control below 0.3G; otherwise, root damage will occur. Narrow landscape paths (width < 1.2m) with numerous sharp turns impose extreme demands on AGV's minimum turning radius. Additionally, regulations prohibiting chemical drift necessitate centimeter-level path accuracy from the navigation system to prevent accidental contact with rare plants.

Challenges at Open-Air Vegetable Bases: After heavy rains, vehicles become stuck in muddy soil (soil moisture content >35%). Clay soils can cause standard tires to sink up to 15cm deep. Excessive sunlight causes electronic components to overheat, particularly during summer midday when cabin temperatures frequently exceed 70°C, accelerating capacitor degradation. Corrosive fertilizer solutions erode metal supports through irrigation runoff, with ammonia nitrogen components causing corrosion.

Greenhouse Challenges: Internal aisle widths of only 1.0-1.5m require AGVs with bidirectional avoidance capabilities. significant day-night temperature fluctuations cause frequent condensation issues in winter, where water droplets can short-circuit low-voltage interfaces. daily high-pressure rinsing leaves residual chemicals (e.g., sodium hypochlorite) adhering to equipment surfaces, causing metal oxidation; Steel framework obstructs signals, rendering traditional UWB positioning ineffective. Measured signal attenuation reaches up to 80dB, necessitating multi-source fusion algorithms for compensation.
