Abstract
In order to meet the requirement of splitting wood to take out the pests in the plant protection research work, the splitting and taking pest machine is designed, which working mode is based on spiral transmission. According to the wear condition, the main structure parameters of the spiral transmission device for splitting were determined. Furthermore, the strength of the dangerous section of screw rod, the strength of nuts' teeth, the self-lock of spiral pair and the stability of screw rod were checked. The virtual prototype of splitting and taking pest machine is made by using SolidWorks software, the motion simulation results show that no interference among the various parts. The test results of the prototype indicate that the machine can meet the job requirement to split wood and take out the pests. In addition, the machine has many features, such as simple structure, working smoothly and low vibration.
