现有技术中，联合收割机的振动筛安装在滚筒下方，用于筛选作物籽粒，振动筛驱动轴承座安装在振动筛驱动装置安装座上，此安装座为折弯板，折弯板通过焊接的方式固定在收割机机架的尾部的左右侧壁上，折弯板上具有供轴承座安装的安装面，安装面上打连接孔，轴承座对应该连接孔，通过螺栓等紧固件固定在折弯板上。In the prior art, the vibrating screen of the combine harvester is installed under the drum to screen crop grains, and the vibrating screen drive bearing seat is installed on the vibrating screen drive device mounting seat, and the mounting seat is a bending plate, and the bending plate is welded.

The mounting surface is punched with connecting holes. The bearing seat corresponds to the connecting hole and is fixed by fasteners such as bolts. on a bent plate.
机架满焊后存在变形，从而导致左右折弯板之间的平行度存在误差，进一步会影响两侧轴承座安装的同心度。同时，轴承座先固定在折弯板上，再通过折弯板固定在机架上，振动筛在运转过程中不停地在做往复运动，长时间、高转速、大喂入量作业，仅凭折弯板支撑往复振动的振动筛，稳定性差，存在安全隐患。After the frame is fully welded, there is deformation, which leads to an error in the parallelism between the left and right bending plates, which further affects the concentricity of the bearing housings on both sides. At the same time, the bearing seat is first fixed on the bending plate, and then fixed on the frame through the bending plate. The vibrating screen is constantly reciprocating during the operation, and the long-term, high-speed and large-feeding operation is only necessary. The vibrating screen supported by the bending plate with reciprocating vibration has poor stability and has potential safety hazards.
