| Deep loosening operation can effectively improve the physical and chemical properties of solid, it is an
important measure to achieve sustainable development of farming. To solve the existing problems, such as unreasonable
structure and large traction resistance for general types of deep loosening machines, a type of vibrating deep loosening
machine was developed based on vibration principle in order to reduce the traction resistance. The main structural
parameters of Shank, stubble cutting disk cutter, crank rod system, depth wheel and frame were determined. The results of
machine performance test showed that the machine was reasonable designed and had a high trafficability characteristic.
Contrastive experiment of vibrating and non-vibrating subsoiling operating with 30 cm plowing depth was carried out in
arid corn field, and the result showd that the traction resistance reduction effect was obvious, and traction resistance could be reduced by 21.24%. |
