Large-amplitude anti-blocking coal chute

大振幅防堵落煤管

Abstract

The utility model discloses a large-amplitude anti-blocking coal chute which comprises a coal conveying pipe and a coal chute body. The outer diameter of the tail end of the coal conveying pipe is smaller than the inner diameter of the head end of the coal chute body, the head end of the coal chute body is movably connected with the tail end of the coal conveying pipe, and a vibrator is arranged at the tail end of the coal chute body. The large-amplitude anti-blocking coal chute can effectively prevent coal bonding and blocking, the coal chute vibrates with a rotation shaft or a connection rod as a center through the effect of the vibrator, so that the coal stream surface of the coal chute can vibrate at large amplitude, coal bonded in the coal chute can be loosened, and the purpose of block breaking and dredging is achieved.
本实用新型公开了一种大振幅防堵落煤管,包括输煤管和落煤管,所述输煤管尾端的外径小于落煤管头端的内径,在落煤管头端和输煤管尾端活动连接,在落煤管的尾端安装有振动器。本实用新型落煤管能有效防止粘结堵煤。落煤管以旋转轴或连接杆为中心在振动器的作用下发生振动,使落煤管的煤流面能大幅度振动,从而疏松落煤管中粘结的煤,达到破堵疏通的目的。
