The full name of the foldable hydraulic disc rake is the suspended hydraulic folding medium-sized opposed disc rake. Unlike ordinary fixed amplitude disc rakes, this machine is equipped with hydraulic folding wing rakes on both sides, which can be unfolded to achieve ultra wide and wide land leveling during operation;
When transporting by road, storing in warehouses, or crossing narrow roads, hydraulic pressure can be used to retract the rake groups on both sides, greatly reducing the overall width of the machine and perfectly adapting to large-scale field farms for contiguous land preparation and cross regional agricultural machinery operations. It is the mainstream land preparation equipment for large farms in Europe, America, Central Asia, and Russia.
The standard double wing folding medium-sized circular disc rake adopts a double opening bidirectional rake group structure.
The foldable hydraulic disc rake is an upgraded wide model of opposed (split) disc rake, with two core features:
Symmetrical arrangement of rake groups: front, rear, double row, left and right rake groups flip the soil in reverse, driving without deviation, and the ground surface is flat;
Equipped with hydraulic folding wing cylinders on both sides, the left and right auxiliary rakes can be easily retracted and folded upwards with one click, achieving wide width operation and narrow width road transportation. The national standard model 1BZDZ (hydraulic folding opposed disc rake) is divided into light, medium, and heavy types, mostly traction/semi suspension, suitable for large tractors with over 120 horsepower and large-scale farms.
Core structure composition
Middle fixed main beam: the main body of the machine, connected to the tractor towing frame/three-point suspension;
Left and right folding wing rake assembly: hinged on both sides of the main beam, driven and retracted by a double acting hydraulic folding cylinder;
Double row opposed rake assembly: the front row flips the soil outward, and the rear row retracts the rake inward to eliminate ridges and grooves;
Transport walking wheel+lifting oil cylinder: the whole machine is supported on the ground during road transportation and lifted during field operations;
Mechanical safety locking mechanism: automatically locks when folded in place to prevent the wing panel from accidentally opening during driving;
Adjustment components: rake angle adjustment, scraper plate, depth limiting device.
Working and Folding Principles
1. Field operation mode (fully extended wings)
Spread the left and right rake groups horizontally to form a super large operating width of 4-9 meters; The symmetrical split structure offsets lateral thrust, ensuring stable straight-line driving of the tractor, even soil crushing, stubble removal, and fertilizer mixing, without unilateral soil stacking.
2. Road transportation mode (hydraulic folding and folding)
Operate the hydraulic handle of the tractor, pull the wing rakes upward and inward with the oil cylinders on both sides, and compress the horizontal width of the whole machine to 2.5-3 meters, which meets the standards for highway traffic; The locking mechanism fixes both wings and is equipped with walking wheels for full traction and transportation, without the need to disassemble machinery.
