Do you know how to correctly use disc plow? Let's go to see today's blog
Compared with other types of soil tillage machinery (spike-tooth harrow, moldboard plow, rotary tiller, etc.), disc-type soil tillage machinery (disc harrow, disc plow, etc.) has the advantages of simple structure, high productivity, not easy to be blocked by plant residues, strong ability to overcome obstacles, less wear on working parts, better guarantee of ground operation quality, thus promoting the improvement of crop yield, etc. Therefore, disc-type soil tillage machinery has been widely used and developed all over the world. The disc heavy-duty (swamp) harrow is used for post-cultivation harrowing of uncultivated land, especially for valley bottoms and swamps. This machine can be effectively used for the development and improvement of grasslands and pastures; it is widely used for post-harvest cultivation of row crops and cereal crops on heavy clay soils, and often replaces moldboard plows in basic cultivation. The shallow tillage machine can till the soil to a depth of 4 - 6 cm, and can ensure a stable stubble removal depth during operation. When deep tilling in soils with low humidity and high specific resistance, it will be more ideal to use a 1-7 disc plow. The disc of a shallow tiller becomes blunt and loses its cutting ability, which will lead to a decrease in soil tillage quality and a worsening of the cutting of stubble and weeds. Therefore, double-layer metal discs with automatic sharpening effects are more popular among growers. Generally, the cutting edge of a disc is worn out after 3-4 years of use, which reduces the diameter of the disc. The service life of the shallow tiller can be extended to 7 years.
Before using the disc plow, it is necessary to check the working parts such as the universal joint drive shaft, plow blades and gear box parts. In actual operation, the plowing depth, deflection angle and other parameters of the disc plow should be adjusted according to the soil conditions and tillage requirements. If the soil is hard/wind eroded, the plowing depth should be appropriately reduced; if there are many weeds and the soil is wet and heavy, the deflection angle and plowing depth can be appropriately increased. When the machine is in use, no one is allowed to stand behind or around it to prevent flying soil from injuring people; it is strictly forbidden to enter the soil first and then engage the power output shaft, or to suddenly lower it into the soil to cause damage to the machine. After the operation is completed, the plow body should be cleaned of weeds and silt, and the wear of the machine should be checked regularly to avoid overloading the tillage machinery and increasing fuel consumption.
There are several main reasons why disc plows are difficult to enter the soil:
Disc plow factors
- Blade problem: The plow blade is worn and blunt or the blade is too thick, which increases the resistance when entering the soil and makes it difficult to cut into the soil.
- Insufficient counterweight: The whole machine is not counterweighted enough, resulting in insufficient downward pressure on the soil by the plow body, making it difficult to penetrate the soil smoothly.
- Improper deflection angle: The deflection angle of the disc plow is not set properly. If the deflection angle is too small, the plow body will weaken the ability to cut and enter the soil.
Soil condition factors
- Too hard soil: For example, when working on the land with high clay content and severe compaction, the soil is firm and the difficulty of the disc plow entering the soil will increase.
- Improper soil moisture: The soil is too dry, the friction between particles is large, and the plow body is not easy to cut into the soil; and when the soil moisture is too high and muddy, it is easy to cause
the disc to be stuck and difficult to enter the soil.
Operation-related factors
- Too fast operation speed: The tractor drives the disc plow too fast, so that the plow body is dragged away before it can enter the soil normally, affecting the soil entry effect.
- Unreasonable ploughing depth adjustment: The ploughing depth is set too deep, exceeding the normal soil entry capacity of the disc plow, which is prone to soil entry difficulties.
Equipment installation and maintenance factors
- Irregular installation: For example, when the disc plow is installed, the components are not firmly connected and there is looseness, which affects the overall soil entry performance.
- Lack of maintenance: The disc plow has not been cleaned, lubricated, and other maintenance work for a long time, resulting in inflexible operation of the components and difficulty in soil entry.
