A virtual prototype of oblique rotary tilling based on SPH(Smooth Particle Hydrodynamics) was developed. Digital simulation and field test of oblique rotary tilling were conducted. The digital simulation suggested that soil mainly was torn to failure during oblique rotary tilling. Therefore, oblique rotary tilling could save energy. The given power consumption comparison of digital simulation a...

Tillage is the most energy-intensive soil operation. In actual energy situation important to explore and analyze physical laws of cultivation processes, that demand large quantities, at border technical- agricultural sciences. We studied phenomenon’s occurring during work with a rotary tiller approximated requirements computer simulation using Matlab Simulink environment. The model used was sim...

In order to increase the structural performance of rotary tillage knife, a badger claw toe was selected as bionic prototype and optimization design knife carried out. The similarity between badger’s tiller is 0.7073 by fuzzy algorithm, shape goodness fit final mole’s digging shovel 0.9556 MATLAB. Using 3D modeling software NX10.0, we established three-dimensional model knife. Furthermore, use W...

A rotary tiller or rotavator is active tillage equipment used to prepare farmland for sowing seeds, weeding, mixing manure and fertiliser into the soil, crushing soil blocks, etc. Compared with conventional farming, advantages of this are rapid seedbed preparation reduced draught. Nowadays, utilisation rate tillers has increased. However, blades key component that engages in tiller. These inter...
