Cultivation and hilling are important steps in crop field management and provide an important guarantee of crop quality and quantity. With the aim of addressing how the soil flow direction of a traditional cultivation and hilling machine is difficult to control, and because it is difficult to achieve high ridge soil cultivation, among other issues, the components of the soil flow direction control of a hilling machine was designed. The components of the soil flow direction control consisted of a soil-feeding plough device, spiral knives and guide cover devices, etc. The design and analysis of the guiding parts for the two tools of the soil-feeding plough device and the spiral knife were performed to obtain an appropriate guide wall and helix angle. The guiding principle in the flow direction control components was analyzed. The design of the guide wall adopts the torsional columnar plough surface, and the elementary line angle changes from stable to increasing. The analysis of spiral milling showed that when the spiral angle is large, the milling effect is better. According to the discrete element method, the working part of the machine-soil interaction model was established. EDEM software was used to simulate the control components for the soil flow direction of the hilling machine for compound cutting. The design method with a two-factor comprehensive test was used to study the linear velocity along the outer part of the spiral knife and the influence of the forward velocity of machine of the implement on the soil cultivation effect. The results of the discrete element simulation showed that both the linear velocity along the outer part of the spiral knife and the forward velocity of the machine have extremely significant effects on the transportation of particles to the ridge top and the hilling thickness. Following multiple comparisons of the average hilling thickness with different linear velocities along with the outer spiral knife and different forward velocities of the machine, it is concluded that the performance of the machine is better when the linear velocity along the outer spiral knife is 3.01 m/s and the forward velocity of the machine is 0.7 m/s. The research conclusion had great theoretical value and practical significance for the design of the machine, which worked for cultivation and hilling.

Small agricultural machinery with forward and reverse-rotational rotary blades was proposed for solving the problem of cultivation with compacted soil. Lagrangian smoothed particle hydrodynamics (SPH) based models of forward and reverse-rotational rotary blades were carried out using the LS-DYNA software. SPH is a mesh free method, thus large material distortions that occur in the soil cutting problem are easily managed. In most earth moving machinery, such as bulldozers or tillage tools, the working tool is a blade. Hence for tillage systems, accurately predicting the forces acting on the blade is of prime importance in helping to enhance productivity. Structural parameters of reverse-rotational rotary blade were studied and optimized with orthogonal test and numerical simulating technology. Results show that forward and reverse-rotational rotary tool can independently work for the cutting of compacted soil with different operating resistance. It is perfectly feasible to apply the proposed composite rotary tiller to compacted soil deep-tilling with low power motor. Proper structural parameters of forward and reverse-rotational rotary blades can reduce the power consumption. This method provides theoretical basis for the design of tools.
