The first is to understand the mud moisture. After harvesting the rice field two nights later, the moisture content of the field mud should be appropriate. Generally, a handful of soil should be grabbed by hand and it should not be clumped. Too wet, equipment can not be under the field; too dry, increase the wear of the equipment.
The second is that the trencher is installed in the middle of the rotary shaft of the rotary cultivator. The original coulters and shells on the rotary cultivator must be removed, and the trencher machine components should be installed. At the same time, the rotary cultivator should be Drive gears and passive gears are swapped to get high speeds. The original rotation speed is 188 rpm, and the speed of 256 rev/min can be obtained after changing to the passive gear. This will help the soil to be chopped and thrown. Generally can be thrown 0.8-1 meters.
Third, the depth of trenching is generally 0.15-0.20 meters. The adjustment method is as follows: Loosen the 6 bolts on both ends of the rear axle of the rotary tiller so that the gap between the upper surface of the surface of the trench cutter and the rotary coulter on the trencher is 5-10 mm, and it is preferable to avoid collision. When the blade is in contact with the ground, the distance between the rotating coulter and the floor is preferably 10-20 mm. When it is necessary to increase the depth of the trench, the rotary coulter can be slightly larger than the ground clearance.
The fourth is the soft paddy fields in Tianni. The speed of hand-dragging can be used to block II. For paddy fields with hard mud, the walking speed can be blocked by I. In the trenching operation, the engine speed should be controlled above the medium and high speed, the rotation speed is high, and the soil is easily broken and scattered.
Fifth, attention should be paid to safety when operating the machine. When the implement is moved in the field, the trencher should be turned to rotate the tool and the safety should be transferred at a low speed. When starting work, the operator should wear protective glasses to prevent splashing into the eyes. When adjusting the maintenance equipment, it should be done with the engine shut down.
