500L Oil-Electric Hybrid Remote Crawler Air Blast Sprayer, Dual 48V Brushless Motor Tracked Fruit Tree Spraying Machine

1. Product Overview

This 500L remote controlled crawler air blast orchard sprayer is a heavy-duty professional spraying equipment tailored for large-scale fruit plantations, mountain orchards and ecological forest bases.

It adopts advanced oil-electric hybrid dual-power design, separating the walking driving system and spraying fan power system completely, to ensure uninterrupted and stable spraying performance even when climbing slopes or turning. The crawler chassis is powered by dual 48V high-efficiency brushless motors matched with our self-developed heavy-load reduction gearbox, delivering strong load-bearing capacity and outstanding durability. The standard 800mm large-diameter air blast fan generates powerful long-distance airflow, which can send fine mist deep into dense tall fruit tree canopies. Wireless remote control allows operators to work far away from toxic pesticide mist, greatly improving operation safety. The wear-resistant rubber crawler chassis adapts perfectly to muddy orchard ground, steep hillsides and narrow tree rows, making it the ideal high-efficiency spraying solution for modern large orchard farms.

2. Core Product Advantages

✅ 500L Extra Large Anti-Corrosion Liquid Tank

The thickened integrated liquid tank boasts a huge 500-liter capacity, drastically cutting down the frequency of liquid refilling and supporting continuous all-day spraying operations for large orchards. The tank is constructed from acid and alkali resistant special plastic material, fully compatible with all types of pesticides, fungicides, foliar fertilizers and disinfection liquids. The sealed liquid filling port effectively prevents liquid splashing during uphill travel or sharp turns, and the tank body is firmly locked onto the crawler frame to eliminate shaking during heavy-load operation.

✅ Oil-Electric Hybrid Dual Independent Power System

This machine features an innovative oil-electric hybrid dual-power structure that divides power supply into two independent modules:

Crawler walking system: Driven by dual 48V brushless motors, supplying stable high torque for heavy-load carrying, uphill climbing and flexible turning.

Air blast fan & high-pressure spraying pump: Powered by an independent gasoline engine, outputting constant wind pressure and atomization pressure without performance loss caused by chassis movement.

Compared with single-power sprayers on the market, this dual-power design achieves higher spraying efficiency and more consistent atomization effect. Spraying strength will not weaken even when the machine is climbing steep slopes or shuttling between tree rows.

✅ Dual 48V Brushless Motors & Self-Developed Heavy-Duty Reduction Gearbox

The walking assembly is equipped with two sets of high-performance 48V brushless drive motors, featuring low energy consumption, low running noise and stable power output. Each motor is matched with our exclusive self-developed heavy-load reduction gearbox. The gearbox adopts thickened alloy gear components with excellent wear resistance, impact resistance and high load-bearing capacity. It easily handles harsh working conditions such as full liquid tank heavy loads, bumpy mountain roads and long-term uphill climbing, reducing motor wear and greatly extending the overall service life of the walking driving system.

✅ Standard 800mm Large-Diameter Air Blast Fan

The machine is equipped with an 800mm diameter large air blast fan as standard configuration, specially designed for tall, dense fruit trees including apple, pear, walnut, longan, lychee and other high-canopy economic fruit trees. The oversized fan generates strong, far-reaching airflow that penetrates deep into dense inner tree crowns, delivering fine atomized mist to the front, back and bottom of leaves, branches and fruit surfaces for full coverage. This greatly improves pesticide adhesion rate and reduces chemical waste, significantly boosting the pest and disease prevention effect of orchards.

✅ Full Wireless Remote Control for Safe Operation

All core working functions are fully controllable via wireless remote operation, including machine forward, backward, left and right turning, fan start & stop, spray switch and chassis speed adjustment. Operators can stand at a safe distance to remotely control the entire machine, completely avoiding direct inhalation of toxic pesticide mist and effectively preventing pesticide poisoning accidents. The remote controller adopts simple button layout with intuitive operation logic, which field workers can master quickly without complicated professional training.

✅ All-Terrain Wear-Resistant Rubber Crawler Chassis

Heavy-duty rubber tracks with deep anti-slip patterns provide powerful ground gripping force, enabling stable and smooth travel on muddy orchard soil, wet steep hillsides, soft farmland and uneven mountain terrain without slipping or sinking. The compact fuselage design supports small-radius flexible turning, allowing the machine to shuttle freely through narrow gaps between fruit tree rows without scratching tree trunks, tender branches or fruits, effectively improving the overall field operation efficiency of large orchards.

✅ Wide Multi-Scenario Application Range

Large Commercial Orchard Pest & Disease Control: The core spraying equipment for apple, pear, citrus, walnut, longan, lychee and other large-scale fruit tree plantations, completing full-coverage pesticide spraying, insecticide and disease prevention work.

Greenhouse & Seedling Nursery Maintenance: Suitable for regular disinfection, insecticide and nutrient liquid spraying of vegetable greenhouses, flower planting bases and seedling breeding nurseries.

Livestock & Poultry Farm Disinfection: Applied to large-area epidemic disinfection of livestock breeding farms, poultry houses and livestock pens.

Landscape & Ecological Forest Maintenance: Ideal for insecticide spraying of park landscape trees, urban green belts and mountain ecological protection forests.
