According to the special terrain of terraced fields in the southwest, a small integrated rice cart is designed, which consists of rice cutting device, rotating guide device, transmission device, rice beating device and vibrating screen device. The whole device is coordinated and cooperated with each other, which integrates rice cutting, rice feeding, rice beating and rice collection, improves working efficiency, reduces labor intensity and saves manpower and material costs. Rice cutting device, rice beating device, etc. can complete the whole process of rice cutting and collection, and thresh directly, so as to avoid the loss of grains caused by too many intermediate steps. The design of triangular wheel treads makes the rice cart convenient for cross-floor operation and more suitable for terraced terrain. The whole integrated rice cart not only breaks through the constraints of environmental factors such as terrain, but also avoids the complicated process of manual rice harvesting. Moreover, the device is relatively small in size and quality, has strong adaptability, improves the efficiency of harvesting rice, reduces the labor intensity, avoids the loss of seeds caused by intermediate processes such as transportation operations and field operations, and has good energy saving and emission reduction benefits.
