400L Electric Hybrid Remote Crawler Air Blast Sprayer, Dual 48V Brushless Motor Tracked Fruit Tree Spraying Machine

1. Product Overview

This 400L remote controlled crawler air blast sprayer is a high-performance agricultural spraying equipment independently developed for medium and large fruit orchards, mountain planting bases and ecological parks.

It adopts an advanced oil-electric hybrid power solution, separating walking power and spraying power to ensure stable operation and high working efficiency. Equipped with dual 48V brushless drive motors paired with self-developed heavy-load reduction gearboxes, the machine delivers strong bearing capacity and long service life. Customers can freely select 600mm or 800mm diameter air blast fans to match low dwarf fruit trees and tall dense fruit trees respectively. The wireless remote control operation avoids direct contact with pesticide mist, greatly improving operator safety. The wear-resistant rubber crawler chassis adapts to muddy orchards, steep slopes and narrow tree rows, making it an ideal professional spraying machine for modern large-scale orchard planting.

2. Core Product Advantages

✅ 400L Large-Capacity Anti-Corrosion Liquid Tank

The thickened integrated liquid tank has a volume of 400 liters, which greatly reduces the frequency of liquid refilling and supports uninterrupted long-hour spraying for large orchards. The tank is made of acid and alkali resistant special plastic, compatible with all kinds of pesticides, fungicides, foliar fertilizers and disinfectants. The sealed liquid inlet prevents liquid splashing during climbing or turning, and the tank body is firmly fixed on the crawler frame to avoid shaking during operation.

✅ Oil-Electric Hybrid Dual Independent Power System

This machine adopts an innovative oil-electric hybrid dual-power design, which completely separates the walking drive system and the spraying fan system:

The walking chassis is driven by dual 48V brushless motors, providing stable torque for climbing, turning and heavy-load carrying.

The air blast fan and high-pressure spraying pump are driven by an independent gasoline engine, which outputs constant wind pressure and spraying pressure without power loss caused by chassis walking.

Compared with single-power sprayers, this dual-power design delivers higher spraying efficiency and more stable atomization effect, and will not reduce spraying performance when the machine climbs slopes or turns.

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

The crawler walking system is equipped with two sets of 48V high-efficiency brushless drive motors, with low energy consumption, low noise and strong power output. Matching our self-developed customized motor reduction gearbox, the gearbox adopts thickened alloy gear structure, with strong load-bearing capacity, wear resistance and impact resistance. It can easily cope with heavy load conditions such as full liquid tank, uphill climbing and bumpy terrain, effectively reducing motor loss and greatly extending the overall service life of the walking drive system.

✅ Optional 600mm / 800mm Diameter Large Air Blast Fans

Two specifications of fan assemblies are optional to meet the spraying demands of different types of fruit trees:

600mm diameter fan: Suitable for dwarf fruit trees, young saplings, citrus, peach and other short canopy fruit trees. The wind force is soft and concentrated, which can fully cover the inner and outer layers of short tree crowns without excessive mist drift.

800mm diameter fan: For tall, dense fruit trees such as apple, pear, walnut and longan. The super large fan outputs strong far-reaching airflow, which can send fine atomized mist deep into the dense inner canopy of tall trees, realizing full coverage of branches, leaves and fruit surfaces, and significantly improving pesticide utilization rate.

✅ Full Wireless Remote Control, Safe & Easy Operation

All core functions are controlled by wireless remote operation, including machine forward, backward, left and right turning, fan start-stop, spray switch and speed adjustment. Operators can stand at a safe distance to control the machine, completely avoiding inhalation of toxic pesticide mist and effectively preventing pesticide poisoning accidents. The remote controller features simple buttons and intuitive operation, which can be quickly mastered by field workers without complex training.

✅ All-Terrain Wear-Resistant Rubber Crawler Chassis

Heavy-duty rubber tracks with deep anti-slip patterns provide powerful ground gripping force, enabling stable driving on muddy orchard soil, steep hillsides, wet farmland and uneven mountain roads without slipping or sinking. The compact body supports small-radius flexible turning, allowing the machine to shuttle freely between narrow fruit tree rows without scratching tree trunks, branches and fruits, greatly improving field operation efficiency.

✅ Wide Multi-Scenario Application

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

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

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

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