how to use machine Chisel plows
Chisel plows
These plows cut the soil and dismantle and dispersion without changing the ground section only slightly. They release some of the clays on the surface of the soil, which can then be destroyed by using combs, and they cut the weeds from under the surface of the soil and uproot the roots of the previous plants. It is feared that if this type of plows does not turn the surface of the earth into a full heart, it is used in lands whose fertility is concentrated in the surface layer. The following:
1. Soil is given good natural properties, especially if the field is plowed twice in two directions perpendicular, followed by a combing operation.
2 - does not bring harmful salts on the surface of the soil, which is usually concentrated in the interior as it does not turn the soil.
3 - leaves the dead grass after plowing on the surface to protect the soil from the wind and leaves the surface layer where the roots of plants grow fertile.
4 - The necessary capacity and costs for plowing one acre less when using the drill plow and increase when using any other kind of plows or rotary.
5 - The surface of the soil after the plowing is more level than if a plow was used
6 - These plows do not require great skill to adjust their machines or to work in different fields.
7. In small fields, plows are more economical in time and fuel than other plows or rotary plows.
There are many types of plows that differ in the way they are connected to the tractor, the shape of the bows, the weapons and the plow width. The best results are obtained when the soil is at a certain moisture level.
The drill plows have a set of bronchial tubes, placed at distances of about 25 cm and equipped with sharp weapons that can be changed. The bronchus may be stiff or flexible. where the soil is not intended to be replaced by plows or plows. Since the plows are not enough to break the soil as in the plows, it is necessary to conduct the plowing several times. The first time is called decomposition, the second time is drained, the third time is read and every time the plowing is done in a perpendicular direction on the previous time.
Effect of some Factor upon Draft chisel plows
Many factors affect the tensile force required by these factors, such as the shape and width of the weapon, as well as the trachea and the angle of lifting of the weapon (the angle between the face of the weapon and the horizontal plane). The best angle of lift was found to be 20 °.
The depth of tillage and tillage affect the amount of tensile strength required. The effect of the depth on the qualitative tensile depends on the shape of the weapon and its angles with the soil and soil type and soil condition of moisture and the presence of the remains of plants and stones The results indicate a trend towards increasing the tensile strength with increased depth has been found that the increase in speed increases the tensile strength required for plowing where the tensile strength of 11-16% when the speed increased from 4.8 to 9.6 km / h and generally the specific resistance of these plows ranged from 1.2, 9 N / cm2.
You have shared a nice article here about the Chisel plows machine. After reading your article I got very much information about Chisel plows machine and it resolved many of my doubts. If anyone looking for the Machinery Valuation Services, Chadils is the best for you.
