设计了一种驱动型凿齿式旋耕机,并在实验室土槽内进行了试验。正转凿齿式旋耕机通过土壤产生推力,并将该推力的一部分作为负阻力返回给机组。凿齿式旋耕机比普通凿式犁松动的土壤更多,碎土也更细。根据试验结果和计算的动力传递效率,表明凿齿式旋耕机比普通凿式犁具有更高的能量效率。 A driven gear-type rotary tiller was designed and tested in a laboratory soil tank. Rotary gear rotary tiller through the soil to produce thrust, and part of the thrust as negative resistance back to the unit. Chisel rotary loaders loose soil more than ordinary chisel plow, broken soil is also more detailed. Based on the experimental results and the calculated power transmission efficiency, it is shown that the chisel rotary tiller has higher energy efficiency than the ordinary chisel plow.
