Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The two-stage tamping gangue blocking device for the filling support shown in the attached figures 1-2 comprises: the first connecting plate (2) is provided with a plurality of connecting plates,
two ends of the top of the first connecting plate 2 are vertically connected with a second connecting plate 1, and the bottom of the first connecting plate is provided with a third connecting plate 3;
the second connecting plate 1 is formed by two plates which are oppositely arranged and are parallel to each other, and one side, far away from the first connecting plate 2, of the second connecting plate is connected with a connecting rod 6 through a mounting hole 5;
a plurality of third connecting plates 3 are arranged in a straight line along the length direction of the second connecting plate 1, and a baffle 4 is arranged on one side far away from the first connecting plate 2;
one side of the baffle 4, which is far away from the third connecting plate 3, is arc-shaped;
the connecting rod 6 is parallel to the first connecting plate 2 and the baffle 4.
The working process of the utility model is as follows: the utility model comprises a rigid fixing frame and a baffle plate, wherein a rectangular first connecting plate 2, two square second connecting plates 1 and four square third connecting plates 3 are manufactured by using an iron plate, and a connecting rod 6 is manufactured by cutting waste steel bars; then, two second connecting plates 1 are oppositely placed and vertically fixed at two ends of the top side of the first connecting plate 2, and four square third connecting plates 3 are sequentially and uniformly distributed and fixed at the bottom side of the connecting plates 3 along the length direction of the first connecting plate 2; set up mounting hole 5 at the top of second connecting plate 1, connect connecting rod 6 between two second connecting plates 1 through mounting hole 5, fix baffle 4 at the bottom side of third connecting plate 3 at last, the concave surface of circular arc is towards the one side that the waste rock fell, the during operation is installed on filling support second grade tamping mechanism through rigid mount, its effect is exactly the leather that utilizes the mount to install, block the regional waste rock of filling, prevent at the tamping in-process, the waste rock gets into the back swift current through the space of support second grade tamping with the back swift current, cause the problem of filling waste rock in-process back swift current load increase and filling inefficiency.
