新型仿生啮齿型破骨机

为了解决常用破骨机破碎不均匀的问题，基于仿生学原理，设计了一种新型啮齿型破骨机，适用于畜禽骨产品的 前处理加工。设计了二级破碎机构，通过调节预破碎啮齿辊轮间距，对物料进行一级宽齿破碎，再经过细齿咬合破碎进 行二级破碎，达到所需破碎程度。同时一级宽齿辊轮转速低于二级细齿辊轮转速，避免了一二级破碎齿之间的物料堆 积。设备可显著降低能耗和生产成本，操作简单，维修率低。新型仿生啮齿破骨机适用于多种原料骨的破碎。

A New Type of Bionic Rodent Bone Crusher

ln order to solve the problem of uneven broken bone by crusher, a new type of bionic rodent bone crusher was designed by bionics theory. The equipment was suitable for pretreatment of livestock bone products. The double stage crushing system was designed, and each crushing stage consisted of two crushing roller. The distance of the two crushing roller in the primary crushing stage was adjustable for the variety of bone sizes. Through the fixed hopper, raw bones were sent into the crusher by conveyor belt and broken by the first crushing stage. The crushing blades was strong and sharp, and it mimiced the teeth of the rodent. Then the rough crushed bones fell into the second crushing stage in which they were crushed smaller, because the width of blades on the roller in the second stage was smaller than that of the first stage. The two stages of crushing made products the same size and met the requirement. This bionic bone crusher can reduce the cost and energy consumption, and it is easy to operate and has low maintenance rate. It is applicable to break a vary kinds of raw bones.
