Soil bulk density analyzer to analyze the resistance of soil bulk density to tillage
On the basis of international brush making technology and our own patented inventions, Haixing brush machines are stable and reliable and have been well accepted by the markets. Some of Haixing brush machines can produce different kinds of toilet brushes, dishwashing brushes, and other spherical or semi-spherical brushes. They have the functions of drilling holes, tufting and trimming the filaments.

Because the farmland soil contains agglomerates, organic matter and soil pores, the stress and strain produced by the soil during the action of the farming components on the soil is extremely complicated, and there are still many difficulties in quantitative determination. However, the traction resistance of the tillage is determined mainly by the soil reaction force. The soil reaction force depends on the soil strength and is consistent with the soil cohesion (usually measured by a soil hardness meter or a soil penetration meter, and the units are kg/cm3 and kPa/cm2, respectively). . The main factors affecting soil strength are cornices, organic matter, soil compaction, and moisture content. Therefore, the main factors affecting the tillage resistance are the soil bulk density and the moisture content in the case where the corn root and the organic matter are the same.
The results of soil bulk density test showed that the relationship between the cultivation resistance of the soil and the soil bulk density was a hyperbolic function and could be described by a model. The coefficients were determined by the specific soil conditions. In the case of small soil bulk density, the moisture content has little effect on the crop resistance; and the larger the soil bulk density, the more sensitive the crop resistance to moisture content. From the regression coefficients of the model, it can be seen that the square of the soil bulk density has a significant effect on the cultivation resistance, and the interaction between the bulk density and the water content is not obvious. Therefore, in the case of soil compaction or rolling by the unit, it will cause a drastic increase in the farming resistance and should be taken seriously. The model is relatively simple and has high fitting accuracy and can be used as a PQS relation model. It is of practical significance to estimate the energy input and traction efficiency of field machine operations under similar soil conditions.
