杏仁破壳机设计 250千克，并且在设计过程中杏仁破壳机的制造成本和使用安全性也作为重要的考虑因素，这样的机器可以被广大农民接受以便更好的普及。 关键词：杏仁；分级；破壳 Design of Almond Broken Shell Machine Abstract Almond have great medical value, consumption demand is also increasing, So now many farmers are beginning to grow almonds, planting almonds in some areas have become the main economic crops. In this paper, I mainly design a small almond broken shell machine that the majority of farmers can use. This almond broken shell machine is simple in operation and clear layout of the various mechanism, this machine mainly includes the classification mechanism, transmission mechanism, breaking mechanism and kernel husk separation mechanism , etc. Through the force analysis proved that the necessary condition of almond breaking, analyzed the related mechanism of classification mechanism and the motion data of kernel husk separation mechanism. The almond broken shell machine can obviously increase the rate of shelled almond and reduce the almond broken rate, basic production capacity can reach 250 kg per hour processing .In the process of design, almond broken shell machine manufacturing costs and the use of safety is also an important consideration, such a machine can be accepted by the majority of farmers in order to better popularization.
