The both ends of driving lever 24 are provided with the driven lever 25 that sets up along the length direction of frame 1, driven lever 25 and driving lever 24 mutually perpendicular, and the one end bulb of driven lever 25 is connected in driving lever 24. When the gear motor 522 is started, the output shaft of the gear motor 522 rotates, the first hinge rod 9 rotates around the hinge shaft, so that the angle between the third hinge rod 12 and the fourth hinge rod 13 changes, and at this time, the driving rod 24 moves along the length direction of the frame 1, so as to drive the driven rod 25 to move along the length direction of the frame 1.
Referring to fig. 3 and 5, specifically, the adjusting assembly includes a first connecting rod 27 and a second connecting rod 28 hinged to the first connecting rod 27, the two sides of the frame 1 are both provided with L-shaped frames 26, the L-shaped frames 26 are located at one side of the frame 1 facing the ground, one end of the first connecting rod 27 away from the second connecting rod 28 is hinged to the L-shaped frames 26, and one end of the second connecting rod 28 away from the first connecting rod 27 is connected to one end of the adjusting plate 19 away from the protruding point. The angle between the first connecting rod 27 and the second connecting rod 28 is an obtuse angle, and the hinge point ball of the first connecting rod 27 and the second connecting rod 28 is connected to one end of the driven rod 25 far away from the driving rod 24, and the angle between the first connecting rod 27 and the adjusting plate 19 and the angle between the second connecting rod 28 and the L-shaped frame 26 are acute angles.
Referring to fig. 3 and 5, the adjusting assembly further includes a second support rod 29 hinged at a hinge point of the first link 27 and the second link 28, the second support rod 29 is used for supporting the adjusting plate 19 in an auxiliary manner, the second support rod 29 is in a telescopic arrangement, an angle between the second support rod 29 and the L-shaped frame 26 is an acute angle, one end of the second support rod 29 is hinged at the L-shaped frame 26, and the other end of the second support rod 29 is hinged at a hinge point of the first link 27 and the second link 28. When the operator adjusts the angle adjusting mechanism to change the cutting angle of the cutter 8, the driving rod 24 moves along the length direction of the frame 1 along with the rotation of the bearing plate 6, so as to drive the driven rod 25 to move towards the direction close to the connecting portion 51, and since the first connecting rod 27 is hinged to the second connecting rod 28, the angle between the first connecting rod 27 and the second connecting rod 28 gradually increases along with the movement of the driven rod 25, at this time, since the lengths of the first connecting rod 27 and the second connecting rod 28 are unchanged, the end, close to the clamping mechanism, of the adjusting plate 19 gradually rises relative to the frame 1, so that the opening of the dust hood 20 always keeps a straight line with the tangential direction of the vertex of the cutter 8.
The implementation principle of the embodiment of the application is as follows: before cutting the cable bridge, the worker starts the first driving motor 23 to enable the two screw rods 22 to rotate synchronously, and the lifting rod 4 descends to the position of the cable bridge along the length direction of the screw rods 22. At this time, the worker starts the second driving motor 43 to drive the bi-directional screw rod 41 to rotate, so that the two clamping blocks 42 move toward the direction approaching to each other until the elastic pads abut against two sides of the cable bridge, thereby clamping and fixing the cable bridge for subsequent cutting work.
When the cutting angle of the cutting knife 8 needs to be changed, the operator starts the gear motor 522 to drive the first hinging rod 9 to rotate around the hinging shaft, and as the third hinging rod 12 is hinged with the first hinging rod 9, the second hinging rod 10 is parallel to the first hinging rod 9 and the second hinging rod 10 is hinged with the bearing part 52, the crossing points of the second hinging rod 10 and the third hinging rod 12 are mutually hinged, and a parallelogram is formed among the first hinging rod 9, the second hinging rod 10 and the third hinging rod 12. The first hinge lever 9 rotates around the hinge shaft such that the inner angle of the parallelogram changes. At this time, the angle between the third hinge rod 12 and the fourth hinge rod 13 is changed, so that the cutting angle of the cutter 8 is changed, thereby effectively reducing the situation that the cutting device in the related art can only cut the cable bridge at a fixed angle, and the operator is difficult to adjust the cutting angle of the cutting device.
In addition, because the angle between the bearing plate 6 and the fourth hinging rod 13 changes, the driving rod 24 moves along the length direction of the frame 1, so as to drive the driven rod 25 to move along the length direction of the frame 1, and because the first connecting rod 27 is hinged with the second connecting rod 28, the angle between the first connecting rod 27 and the second connecting rod 28 gradually increases along with the movement of the driven rod 25, at this time, because the length of the first connecting rod 27 and the second connecting rod 28 is unchanged, one end of the adjusting plate 19 away from the salient point gradually rises relative to the frame 1, so that the opening of the dust hood 20 always keeps a straight line with the tangential direction of the vertex of the cutting knife 8, and the synchronous change of the collection angle of the dust hood 20 to the scraps is effectively realized when the cutting angle of the cutting knife 8 changes.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
