I. Product Overview
The tractor root crusher is a professional root processing equipment driven by the tractor PTO (power output shaft), which combines the mobility of a tractor and the efficiency of a professional crusher. The equipment is particularly suitable for scenarios such as orchard renewal, forest land transformation and agricultural waste treatment, and can crush tree roots with a diameter of 10-40cm into wood chips that can be directly returned to the field.
Ⅱ. Core technical parameters
Matching power: 40-120 horsepower, needs to match the tractor PTO speed (540/1000rpm);
Working width: 60-150cm, depends on the size of the knife roller;
Crushing particle size: 3-8cm, replaceable screen adjustment;
Processing efficiency: 0.2-0.6 hectares/hour, depending on the root density;
Equipment weight: 450-1200kg, three-point suspension design;
Ⅲ. Core structure analysis
1. Power transmission system
Adopt heavy-duty universal joint drive shaft (torque load ≥2000N·m);
Standard safety clutch (sliding torque adjustable range 150-180% rated value);
2-stage gear reducer (reduction ratio 1:3.5-1:4.2);
2. Crushing mechanism
Multiple rows of staggered alloy steel hammers (hardness HRC56-60);
Replaceable wear-resistant lining (service life ≥800 hours);
Bidirectional rotation design (forward and reverse switching time <30 seconds);
3. Hydraulic system
Integrated hydraulic lifting device (working pressure 16-20MPa);
Automatic obstacle avoidance protection function (response time <0.5 seconds);
Depth adjustment mechanism (crushing depth 5-25cm adjustable);
IV. Innovative technical features
1. Intelligent protection system: real-time load monitoring through speed sensor, automatically lifting the knife roller when the PTO speed drops by more than 15%;
2. Multi-terrain adaptation design: floating suspension mechanism can adapt to ±15° slope operation, ground pressure <15kPa;
3. Quick knife change technology: patented quick-release structure makes the replacement time of a single hammer <3 minutes;
4. Noise reduction treatment: The internal acoustic package design keeps the operating noise below 82dB(A);
V. Typical application scenarios
1. Orchard renewal: Processing old stumps of fruit trees such as apples and citrus, the crushed wood chips can be directly returned to the field as organic matter
2. Forestry thinning: Cleaning the roots of coniferous trees such as pine and fir, and the work efficiency is more than 20 times higher than that of manual labor
3. Biomass collection: Provide fuel for small rural biomass boilers, and 8-12 tons of dry matter can be collected per hectare
4. Post-disaster treatment: Quickly clean the root parts of trees that have fallen due to ice and wind disasters
VI. Key points of operating specifications
1. Pre-operation inspection:
Confirm that the PTO speed matches the equipment (540/1000rpm);
Check the wear of the hammer (single-side wear>5mm needs to be replaced);
Lubricate all oiling points (use lithium-based grease);
2. Note during operation:
Keep the tractor forward speed at 3-6km/h;
When encountering extra-large tree roots, they should be processed in sections;
Regularly check whether the discharge is smooth;
3. Maintenance after operation:
Clean up the residual wood chips (especially the transmission parts);
Check the torque of the fasteners (key bolt torque 120-150N·m);
Refill the grease of the knife roller bearing every 50 hours;
VII. Selection and matching suggestions
1. Applicable to small orchards:
Matching tractor: 40-60 horsepower
Equipment working width: 80-100cm
Recommended model: TG-100 (self-weight 580kg)
2. Applicable to medium-sized forests:
Matching tractor: 70-90 horsepower
Equipment working width: 120-140cm
Recommended model: TG-135 (self-weight 850kg)
3. Applicable to large-scale operations:
Tractor: 100-120 horsepower
Working width of equipment: 150cm
Recommended model: TG-150 (weight 1150kg)
VIII. Technology development trend
1. Intelligent upgrade: Add GNSS positioning system and operation volume statistics module
2. Material innovation: Carbon fiber composite shell reduces weight by 30%
3. Power diversification: Develop a special version for electric tractors (48V DC drive)
4. Function integration: Integrate additional functions such as deep loosening and fertilization
As a key equipment for agricultural and forestry waste treatment, the technology development of tractor root crusher is rapidly evolving towards a more efficient, smarter and more environmentally friendly direction. Correct selection and use of such equipment can help users reduce the cost of root treatment by more than 60% and realize the recycling of resources.
