Working head and snow shoveling machine
The invention discloses a working head and a snow shoveling machine, and belongs to the technical field of electric tools, the working head comprises a shell, a transmission shaft, a snow sweeping paddle and a limiting device, the shell comprises a main body part and two side wings, and the main body part and the two side wings define a first containing space; the transmission shaft is located in the first containing space and rotates around the first axis, and the two ends of the transmission shaft are connected with the side wings through bearings correspondingly. The snow sweeping paddle is connected with the transmission shaft, at least one side wing is provided with a limiting device, the limiting device has a limiting state, and when the limiting device is in the limiting state, the limiting device drives the two side wings to be away from or close to each other. The snow shoveling machine comprises the working head. When the bearing moves in the axial direction, the bearing can abut against the limiting device, so that the limiting device is in a limiting state, the limiting device and the side wings where the limiting device is located are forced to be subjected to thrust from the bearing to be reversely deformed, the two side wings are made to be away from or close to each other, deformation compensation is achieved, and normal work of the working head is guaranteed.
本申请公开了一种工作头及铲雪机，其属于电动工具技术领域，工作头包括外壳、传动轴、扫雪桨和限位装置，外壳包括主体部和两个侧翼，主体部与两个侧翼围设成第一容纳空间；传动轴位于第一容纳空间内且配置为绕第一轴线转动，传动轴的两端分别通过轴承与侧翼连接；扫雪桨与传动轴连接，至少一个侧翼上设置有限位装置，限位装置具有限位状态，当限位装置处于限位状态时，限位装置带动两个侧翼相互远离或靠近。铲雪机如上所述的工作头。当轴承沿轴向窜动时，轴承能够抵住限位装置，使得限位装置处于限位状态，从而迫使限位装置连同其所在的侧翼受到来自于轴承的推力而反向变形，使得两个侧翼相互远离或靠近，因此实现变形补偿，保证工作头正常工作。
