Description of walk-behind tractor
A walk-behind tractor is a small tractor, a type of transportation tool and agricultural machinery that is popular in Chinese towns and villages. It is powered by a diesel engine. It’s small, flexible and powerful characteristics make it very popular with farmers.
The walking tractor can run by the power of the internal combustion engine through the transmission system, and the driving wheels that obtain the driving torque then give the ground a small, backward horizontal force (tangential force) through the tire pattern and the tire surface. Driving force (also called propulsion). The structure is simple, the power is small, and it is suitable for small arable land. The driver supports the handrail to control the operating mechanism, tow or drive the supporting agricultural implements for operation.
Structure Introduction of Walking Tractor
According to operating performance, it is divided into driving type, traction type, and driving traction combined type. The drive type is mainly equipped with a rotary cultivator, so it is also called power tiller. The traction type is mainly equipped with traction agricultural tool operation. The combined type can be used with both rotary cultivator operation, and with traction agricultural tool operation or with trailer Transport operations. According to the walking device, it is divided into wheel type, track type, and tillage type. Wheeled walk-behind tractors are divided into single and double wheels according to the number of walking wheels.
In order to improve the driver’s working conditions, the walking tractors produced in China added 1 or 2 supporting wheels and installed seats to become riding tractors. Tillage walking tractors, also known as wheelless walking tractors, are characterized by no driving wheels. Instead, a rotary tillage unit is installed on the driveshaft to both cultivate the soil and walk forward. Mechanical structure Walking tractors are generally composed of a frame, a power unit, a drive train, a walking unit, a steering system, a brake, and an operating mechanism.
Horizontal single-cylinder diesel engines are mostly used. The power of the engine is transmitted to the drive train by a V-belt, and the speed of the power is controlled by a clutch. Power transmission through the chain.
The gearbox is transmitted to the gearbox, and the central drive, final drive, steering mechanism, and brakes are all installed in the gearbox. The gearbox adopts gear transmission, and the speed change position varies randomly. Generally, it is 6 + 2 speeds (ie, 6 forward speeds and 2 reverse speeds). The power after the speed change is transmitted to the driving wheels on both sides by the central transmission and the final transmission. The steering mechanism uses a toothed clutch or a copper ball clutch.
The operating mechanism is installed on the handrail to control the throttle, speed change, steering, braking, and power output. Power is directly output from the power output shaft through the gear or directly from the engine. In order to meet the needs of paddy field operations, the walking device is equipped with various iron impellers in addition to the tires and is also equipped with a tail wheel. There are two types of tail wheels, the transport wheel and the tiller wheel. The former is used to support the weight and assist the steering; the latter is used to adjust the plowing depth.
Use of walking tractor
When a walk-behind tractor is towing a one-way double hoe plow, one drive wheel is on uncultivated land and the other drive wheel is in a furrow. The adhesion coefficient between the two wheels and the ground is different, and the slip rates are different, which makes the unit always Yawing in one direction.
For the Aike-1 12 walk-behind tractor, the following adjustments can be made to solve: adjust the gap value (swing gap) between the left and right two adjustment screws on the traction frame and the intermediate connection frame, and the type 681 one-way double hoe plow is adjusted to 1.5mm Left and right, 1LS-220 and 701 type unidirectional double-reed plows are adjusted to about 5 mm.
During the plowing process, if you find that the tractor is still turning to the right, loosen the two fastening screws, short the extension of the left adjustment screw, and turn the extension of the right screw. Until the handrail unit is released, it can travel normally along the trench wall.
Possible causes of yaw during rotary tillage: the rear wheel is deformed, the tail wheel shaft is not installed in the fork, etc., and the tail wheel is deflected: the bearing on the tail wheel shaft is damaged or severely worn: the colter is incorrectly installed or broken, and falls. When deviations occur in rotary tillage operations, relevant parts should be corrected, repaired, reinstalled or replaced according to specific conditions. Before the problem is solved, the steering clutch should not be used for correction, but the method of pushing and pulling the armrest should be used for correction.
When walking tractors for sowing operations. There are two kinds of supporting conditions: one is a trailed seeder. Such as ABQ-8 grain seeder; the second is synchronous transmission ZBG-6A rice and wheat drill. The main reason for the yaw in the planting operation is that the installation height of the seeder (or opener) in the direction of the sowing is inconsistent or left-right asymmetry, the error or breakage of the rotary cutting colter is configured and installed, and the tractor collides Deformation, etc. For the above reasons. During the seeding operation, the resistance in the direction of the seeding range is unequal, which generates a twisting torque, which causes the unit to steer. For this reason, the technical status of the seeder should be carefully checked before the sowing operation, the rotary cutting colter should be configured and installed according to the regulations, and the seeding head (or opener) should be symmetrically configured.
The walk-behind tractor is mainly equipped with 4GL-130 harvester. The main reason for the deviation of the unit is that the gap between the cutters of the harvester is adjusted in different directions. There is a difference in cutting resistance: the cutter is high on the low side, the height of the stubble is different during harvest, and the operating resistance is different. The cutting width is not selected properly. the ground is uneven. Measures should be taken for specific reasons.
The configuration of general walk-behind tractors is mainly 1KSQ-35A (front-mounted) or 1KSH-35A (rear-mounted) small disc trenchers, which are mainly used to excavate field drains. The main reason for the poor straightness of the trenching operation: the deviation between the symmetrical centerline of the cutter head plane and the center plane of the drive wheel shaft of the walking tractor exceeds the specified (1KSQ-35A allowable deviation 8mm, 1KSH-35A allowable deviation 5 mm): the cutter head is distorted, Deformation. The colter was incorrectly installed, and the colter broke, fell off, etc. Attention should be paid to inspection and correction of cutter head and frame. Correctly install the rotary cutting colter, carefully adjust the position of the cutter head, and find that the colter breaks and falls off. Stop immediately and turn off the engine and replace parts.
Irrigation and threshing operations
Equipped with the corresponding water pump and thresher, the diesel engine flywheel belt is connected to the water pump or thresher. The diesel engine flywheel is used to drive the water pump or thresher to be used for irrigation and threshing of wheat and other crops.
Walk-behind tractors with trailers can be used for field transportation or road transport. Generally, 1-ton single-axle trailers are used with 12-horsepower walk-behinds, and the maximum load is 1 ton. Drivers participating in road transport operations must pass the examination of the local traffic management department before issuing a driving license to drive. The tractor should be fitted with direction arrows and mirrors.
