为解决现有纵轴流收割机粮仓布局不合理、整机重心不稳等缺点，设计一种中置

In order to solve the conventional longitudinal flow harvesters granary irrational, the whole center of gravity and other shortcomings in the design of a crawler type opposite longitudinal flow harvester, by a straddle-type layout granaries, granary increased storage space, while the harvester with a stable center of gravity and improve harvesting efficiency and safety performance. The results showed: the total loss was tested samples (1.14% wheat, rice 0.665%), impurity rate (1.065% wheat, rice 0.685%), crushing rate (0.09% wheat, rice 0.01%), the relevant standards requirements, stability, good performance, high safety performance, the model has a good application and promotion value

In order to solve the shortcomings such as unreasonable layout of the existing vertical shaft harvester grain silo and the unstable center of gravity of the whole machine, a mid-center track-type vertical shaft flow harvester is designed to increase the storage space of the granary by riding the cross-type grain silo layout, while making the harvester have a stable center of gravity, improving the harvest efficiency and safety performance. The test results showed that the total loss rate of the test prototype (1.14% wheat, 0.665% of rice), mixed rate (1.065% of wheat, 0.685% of rice), crushing rate (0.09% of wheat, 0.01% of rice), in line with the relevant standard requirements, good stability performance, high safety performance, The model has good application and promotion value

In order to solve the shortcomings of the existing longitudinal axial flow harvester, such as unreasonable grain bin layout and unstable center of gravity of the whole machine, a middle track type longitudinal axial flow harvester is designed. Through the straddle type grain bin layout, the storage space of the grain bin is increased, at the same time, the harvester has a stable center of gravity, and the harvesting efficiency and safety performance are improved. The results show that the total loss rate of the prototype is (1.14% for wheat, 0.665% for rice), the impurity content is (1.065% for wheat, 0.685% for rice), the crushing rate is (0.09% for wheat, 0.01% for rice), which meets the requirements of relevant standards, has good stability and high safety performance, and has good application and promotion value
