Lump coal anti -crushing device

The utility model discloses a lump coal anti -crushing device, include to receive the material cylinder and go out the feed cylinder receive the material cylinder with it is provided with the connecting cylinder to go out between the feed cylinder, receive the material cylinder with connecting cylinder swing joint, receive the material cylinder can for the connecting cylinder rotates, the connecting cylinder with go out feed cylinder fixed connection, wherein, be in be provided with curve deceleration section on the play feed cylinder. It can reduce the speed of lump coal through set up curvedeceleration section on a feed cylinder, makes the slip of lump coal along a curved deceleration section, and speed is too big, the momentum is too big and broken because of directly falling effectively to have avoided lump coal. 本实用新型公开了种块煤防破碎装置，包括受料滚筒和出料筒，在所述受料滚筒和所述出料筒之间设置有连接筒；所述受料滚筒与所述连接筒活动连接，所述受料滚筒能够相对于所述连接筒转动；所述连接筒与所述出料筒固定连接；其中，在所述出料筒上设置有曲线降速段。其通过在出料筒上设置曲线降速段，可以降低块煤的速度，使块煤沿曲线降速段缓慢下滑，有效避免了块煤因直接跌落速度过大、冲量过大而破碎。
