Rotary Tiller Have A Strong Ability To Break The Soil

- Sep 27, 2017 -

The rotary tiller is a farming machine that is equipped with a tractor to complete the tillage and rake operations. Because of its strong ability to break the soil, the flat surface after farming and other characteristics, and has been widely used; at the same time be able to cut the root stubble buried in the surface, easy to sowing operations for the late planting to provide a good seed bed. According to the configuration of the rotary knife axis is divided into horizontal and vertical axis of two categories. Proper use and adjustment of the rotary tiller is important to maintain its good technical condition and to ensure the quality of farming.

There is a strong ability to break the soil, and more for the cultivation of shrubs, marshes and grass wasteland farming. The working parts consist of a rotary tiller roll and a plurality of geared blades uniformly arranged by a plurality of spirals, driven by a tractor power output shaft through a transmission, and a conventional rotational speed of 190 to 280 revolutions per minute. The direction of rotation of the roller is usually the same as the direction of rotation of the tractor wheel. The cutting blade cuts the soil layer from the front and back, and throws the pile back above the cover and the carriage to make it further broken. When the knife roll is soiled and the soil is pressed, the reaction force of the soil to the tool roll helps to propel the unit forward, so the tractor of the horizontal rotary tiller is required to have little traction, and sometimes it can even advance the unit by the knife roll. The cutting blade can be divided into chisel knives, machetes, right angle knives and curved knives. Chisel knives have a narrow front end, have better ability to enter the soil, energy consumption is small, but easy to knit grass, more for weeds less garden and garden. The curved edge of the machete has a sliding effect, easy to cut off the grass and not wrapped around the grass, suitable for rice farming. Right angle knife with vertical and horizontal cutting edge, blade wide, good rigidity, easy to manufacture, but the soil performance is poor. The strength of the curved knife is large, the rigidity is good, and the sliding effect is good, usually used on the heavy rotary tiller. In the following 15 kilowatts tractor matching, the general use of direct connection, without universal joint drive; and 15 kilowatts or more tractor matching, the use of three hanging, universal joint drive; heavy rotary tiller generally used traction. The tillage is controlled and regulated by the carriage or the limited wheel. The trays are located behind the knife roll, and both the crushed soil and the leveling effect; the deepening wheel is located in front of the knife roll. The last stage of the roller is equipped with two kinds of side drive and central drive. The side drive is mostly used for the smaller rotary tiller. Central transmission for the larger tillage of the rotary tiller, the machine's symmetry is good, the machine force evenly; but the transmission box below a strip due to the formation of loose soil blade and the lack of leakage, Of the device.

Mechanical use

1. At the beginning of the operation, the rotary tiller should be lifted, first combined with the power output shaft, the knife shaft speed to the rated speed, and then down the rotary tiller, so that the blade gradually into the required depth. It is strictly forbidden to insert the blade and then combine the power output shaft or the sharp descending rotary tiller to avoid causing the blade to bend or break and aggravate the load of the tractor.

2. In the operation, should be as low as possible slow, so that can guarantee the quality of operations, so that the soil crushed, but also reduce the wear and tear of the parts. Pay attention to listen to the rotary tiller whether there is noise or metal percussion, and observe the broken soil, till the deep situation. If there is any abnormality, it should be immediately shut down for inspection, and then the operation can be continued.

3. When the ground turns, prohibit the operation, the rotary tiller should be raised, so that the blade away from the ground, and reduce the tractor throttle, so as not to damage the blade. When lifting the rotary tiller, the inclination angle of the universal joint should be less than 30 degrees. If it is too large, it will cause the impact noise to be prematurely worn or damaged.

4. In the reverse, over the ridge and transfer the land, the rotary tiller should be raised to the highest position, and cut off the power, so as not to damage the parts. Such as the distant transfer, use a locking device to fix the rotary tiller.

5. After each shift, the rotary tiller should be serviced. Remove the soil and weeds on the blade, check the fastening of the connectors, add lubricating oil to the lubricating oil, and add butter to the joints to prevent aggravating wear.
