Sugarcane is one of the largest economic crops in China. However, the current domestic sugarcane straw crushing and returning machines have limitations such as short service life, poor crushing effect, and low operating efficiency. In order to solve these problems, a 1GYF-240 sugarcane straw crushing and returning machine was developed in this study. First of all, the power is provided by the tractor, and at the same time, it drives the blade in the crushing mechanism to rotate at a high speed. Next, the profiling leaf collector collects the sugarcane stalks that are close to the ground and feeds them into the crushing chamber. Finally, the swinging knife and the fixed knife are used for crushing, and the crushed straw is evenly thrown to the field along the rear baffle under the action of centrifugal force, thereby completing the operation of crushing and returning the sugarcane straw to the field. The results of field experiments show that the qualified rate of sugarcane straw crushing is 93.8%, and the work efficiency is 0.78hm2·h-1, which shows good operation effect. The results of comparative experiments show that this study not only solves the environmental pollution problem of traditional incineration well, but also has the function of heat preservation and water retention. In addition, compared with similar domestic models, the experimental results show that the crushing and returning machine has obvious advantages in picking up rate and crushing rate of sugarcane straw, and has higher reliability in actual operation. This research can provide the foundation and support for the design and popularization of the sugarcane leaf crushing and returning machine. |
