Paddy field rotary tiller is a practical agricultural machinery, welcomed and loved by the majority of farmers, so how to use paddy field rotary tiller? Here we will introduce the use of paddy rotary tiller skills.
How is the paddy field rotary tiller used
First, appropriate amount of water. Too much water, the field is not easy to pulp, can not meet the quality requirements; Too little water makes the fields difficult to rake. It will also increase the friction resistance of farm tools in the soil. Therefore, the general should master in the field before the rotary rake 2-4 hours into the good water, the depth of 6 to 8 cm. Soil that has been plowed should be soaked to a suitable depth at the tip of the soil.
Two, plow knife installation. The installation direction of rotary tiller elbow is determined according to the soil surface condition. In flat ridge operation, the elbow of the plow knife is installed outwards; In trench filling operation, the elbow of the plow knife is installed inward; General ploughing, plow elbow mixed installation. In order to reduce the direct contact of rice straw mixed apples with the plow shaft, the two bolts should be lengthened by about 10 cm when the two plow blades are installed on the left and right side of the plow shaft to eliminate the phenomenon of the plow shaft tangled with grass.
Three, rotary rake speed. The forward speed of the walking tractor and the rotating speed of the plow blade shaft shall be determined according to the specific situation. For the unplowed paddy field, the tractor can choose the slow second gear and the plow shaft can choose the low speed. For the second and third rotation and ploughed paddy field, the tractor can choose the slow third gear and the plow shaft can use the rotating speed.
Four, walking direction. Many machine operators use the sleeve harrow method, so that the field edge formed heavy harrow ring, consuming time and oil. The correct method should be the oblique rake method, that is, the locomotive along the diagonal of the field to the left or right of a rake width began to rake, gradually expand outward, around the edge of the field can be raked a circle. This method has high efficiency, less fuel consumption and good quality.
Five, rake field times. According to the agronomic requirements of rice planting, the paddy field is generally raked two to three times. Planting the field manually, it is better to rake twice. Too many harrow times will destroy the soil grain structure, easy to cause soil compaction, and will accelerate the wear and fuel consumption of agricultural machinery and tools: uneven harrow, less harrow can not meet the agronomic requirements.
Six, beware of sliding. Before operation, use bamboo poles to fill ponds and ditches and make marks. Once sliding, can take the method of self-rescue pile, that is, in the front of the locomotive about 5 meters to play a stake, the wire rope tied to the stake, the other end is tied to the driving wheel. Shift, shake the handle and turn the crankshaft to make the tractor walk, and pull the tractor out of the pit through the wire rope wound around the drive wheel. In addition, it can also be used to pull out cattle or a large power tractor.
