花生收获集晒机的设计

The Design of the Peanut Harvesting and Drying Machine

针对我国的花生种植区存在不同粘结的土壤,在花生收获时铲起的土块不易脱落及花生果粒易掉落的问题,为适应各地不同土壤的要求以提高花生收获质量,设计开发了花生收获集晒机。此花生收获集晒机主要由机架、铲刀、齿盘、内导板、外导板等组成。其特点是在铲刀的后面设有振动器,安装于铲刀尾部并向后延伸的多支齿条,且振动器的振幅和频率均为可调。此机具在花生收割作业时,振动器能把铲起的土垡散开,避免花生果粒脱落,能够适应多种土壤条件。该机具设计合理,为我国花生收割提供了有效的技术支持。

A type of wireless sensor network （WSN） was designed for field information collection to solve the existing problems as battery replacement difficulties and inconvenience. The node use MSP430F1611 as the processing core, Si4432 as wireless communication module, and using solar panels and rechargeable lithium battery as the power supply way. The node program were designed based on the hardware platform, choose the disturbance observation as the sun MPPT algorithm and adopted adjacent node data combination method to deal with data. In this paper, test the node power, solar charging time, and the relationship between communication distance and packet loss rate and the relationship The results show that the design can satisfy the application requirement of field information collection, can make the systern work stability and in low power consumption.
