气吹式筛网防堵装置及秸秆粉碎机
摘要：
本实用新型涉及农业机械技术领域，涉及一种气吹式筛网防堵装置及秸秆粉碎机。该气吹式筛网防堵装置，应用于秸秆粉碎机，该秸秆粉碎机包括机筒、粉碎主轴和设置在机筒侧壁上的至少一个筛网；该气吹式筛网防堵装置包括底座、支撑柱和喷气嘴；底座上固定设置支撑柱；支撑柱上固定设置有喷气嘴；支撑柱内设置有与喷气嘴连通的支柱空腔；喷气嘴用于与筛网的位置对应且喷气嘴喷射的气流能够入射到筛网的网孔内；底座用于与粉碎主轴连接或底座与驱动组件连接。该秸秆粉碎机包括机筒、粉碎主轴、筛网和气吹式筛网防堵装置。本实用新型的目的在于提供气吹式筛网防堵装置及秸秆粉碎机，以解决现有技术中存在的筛网的网孔极容易发生堵塞的技术问题。
摘要（英）：

The utility model relates to the technical field of agricultural machinery, and relates to an air-blowing type screen anti-blocking device and a straw pulverizer. The air-blowing type screen anti-blocking device is applied to the straw pulverizer, and the straw pulverizer comprises a machine barrel, a pulverizing main shaft and at least one screen arranged on the side wall of the machine barrel; the air-blowing type screen anti-blocking device comprises a base, a supporting column and an air nozzle. A supporting column is fixedly arranged on the base; an air nozzle is fixedly arranged on the supporting column; a supporting column cavity communicated with the air nozzle is formed in the supporting column; the air nozzles are used for corresponding to the screen in position, and airflow jetted by the air nozzles can be jetted into meshes of the screen. The base is used for being connected with the crushing spindle or the driving assembly. The straw pulverizer comprises a machine barrel,a pulverizing main shaft, a screen and an air-blowing type screen anti-blocking device. The utility model aims to provide an air-blowing type screen anti-blocking device and a straw pulverizer, and aims to solve the technical problem that meshes of a screen in the prior art are extremely easy to block.
