Environment-friendly energy-saving green and coarse feed grinder

The utility model relates to an environment-friendly and energy-saving green and coarse fodder grinder which effectively solves the problem that certain potential safety hazards exist in the feeding process of an existing grinder. According to the technical scheme, matched negative pressure feeding rollers are arranged at the position of a feeding port of the pulverizer, and then plants moving to the position of the feeding port are fed into the pulverizer under the action of negative pressure; when a worker pushes the plants stacked at the position of the feeding port inwards with the help of tools such as a wood stick, potential safety hazards cannot be generated. 本实用新型涉及一种环保节能型青粗饲料粉碎机，本实用新型有效解决了现有的粉碎机在进行送料时存在一定安全隐患的问题；解决的技术方案包括：该粉碎机进进料口位置处设有相配合的负压送料辊，进而实现将移动至进料口位置处的植株在负压的作用下送入至粉碎机内部，针对一些体积小且短的植株，工作人员借助木棍等工具将堆积在进料口位置的植株向里推送时，也不会产生安全隐患。
