Abstract: Aiming at the problem of domestic forage Crusher lower adaptability, high power and unstability effect of rollers flattening in harvesting Alfalfa, and in order to improve practicability of forage Crusher based on the difference biomechanical characteristics between harvesting terraced dryland Alfalfa and irrigated Alfalfa, the effictive power of forage Crusher flattening system equiped with Tooth-cutter was designed and application, V shape flattening device in 9GYQ family of forage Crusher were developed by using Solidworks software. Setting steel rollers with 5mm deepth flattening device parameters and rubber rollers with 15mm depth were selected to orthogonal testtests and statistical analysis, respectively. Field tests results of 9GYQ family of forage Crusher show that: For terraced dryland Alfalfa Long dong, Rubber rollers were selected with initial pressure of 2200N/m, flattening gaps is adapt to 4 mm, inclination angle of 20°, respectively, and the average ratio of crushing is up to 90.77%% and the loss rates of forage is up to 3.51%% in field tests; For irrigated Alfalfa, rubber rollers were selected with initial pressure of 1650N/m, flattening gap 3 mm, inclination angle of 30°,respectively, and the average ratio of flattening is up to 91.889%% and the loss rate of broken forage is up to 3.479%% in field tests.Abstract: Aiming at the problem of domestic forage Crusher lower adaptability, high power and unstability effect of rollers flattening in harvesting Alfalfa, and in order to improve practicability of forage Crusher based on the difference biomechanical characteristics between harvesting terraced dryland Alfalfa and irrigated Alfalfa, the effictive power of f...Show More
