Referring to fig. 3 and 5, in particular, the adjusting assembly includes a first connecting rod 27 and a second connecting rod 28 hinged to the first connecting rod 27, L-shaped frames 26 are disposed on both sides of the frame 1, the L-shaped frames 26 are located on one side of the frame 1 facing the ground, one end of the first connecting rod 27 far away from the second connecting rod 28 is hinged to the L-shaped frames 26, and one end of the second connecting rod 28 far away from the first connecting rod 27 is connected to one end of the adjusting plate 19 far away from the salient point in a ball joint manner. The angle between the first link 27 and the second link 28 is an obtuse angle, the ball joint of the first link 27 and the second link 28 is connected to the end of the driven rod 25 away from the driving rod 24, and both the angle between the first link 27 and the adjusting plate 19 and the angle between the second link 28 and the L-shaped frame 26 are acute angles.
Referring to fig. 3 and 5, the adjusting assembly further includes a second supporting rod 29 hinged to a hinge point of the first connecting rod 27 and the second connecting rod 28, the second supporting rod 29 is used for assisting in supporting the adjusting plate 19, the second supporting rod 29 is telescopically arranged, an angle between the second supporting rod 29 and the L-shaped frame 26 is an acute angle, one end of the second supporting rod 29 is hinged to the L-shaped frame 26, and the other end of the second supporting rod 29 is hinged to the hinge point of the first connecting rod 27 and the second connecting rod 28. When the staff angle adjustment mechanism makes the cutting angle of cutting knife 8 change, the driving rod 24 moves along the length direction of frame 1 along with the rotation of loading board 6, thereby drive the driven rod 25 towards the direction that is close to connecting portion 51 and move, because first connecting rod 27 is articulated mutually with second connecting rod 28, along with the removal of driven rod 25, the angle between first connecting rod 27 and the second connecting rod 28 crescent, at this moment, because the length of first connecting rod 27 and second connecting rod 28 is unchangeable, the relative frame 1 of one end that regulating plate 19 is close to fixture risees gradually, make the opening of dust cage 20 remain a straight line with the tangential direction on the summit of cutting knife 8 all the time.
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 synchronously rotate, 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 bidirectional screw rod 41 to rotate, so that the two clamping blocks 42 move towards the direction of approaching each other until the elastic pads abut against the two sides of the cable tray, thereby clamping and fixing the cable tray for subsequent cutting work.
When the cutting angle of the cutting knife 8 needs to be changed, the worker starts the speed reduction motor 522 to drive the first hinge rod 9 to rotate around the hinge shaft, the third hinge rod 12 is hinged to the first hinge rod 9, the second hinge rod 10 is parallel to the first hinge rod 9, the second hinge rod 10 is hinged to the bearing portion 52, the intersection point of the second hinge rod 10 and the third hinge rod 12 is hinged to each other, and a parallelogram is formed among the first hinge rod 9, the second hinge rod 10 and the third hinge rod 12. The first hinge lever 9 rotates about the hinge shaft so that the inner angle of the parallelogram changes. At this moment, the angle between the third hinge rod 12 and the fourth hinge rod 13 is changed accordingly, so that the cutting angle of the cutting knife 8 is changed, and the situation that the cutting device in the related art can only cut a cable bridge according to a fixed angle, and the cutting angle of the cutting device is difficult to adjust by a worker is effectively reduced.
In addition, because the angle between the bearing plate 6 and the fourth hinge rod 13 changes, the driving rod 24 moves along the length direction of the rack 1, thereby driving the driven rod 25 to move along the length direction of the rack 1, because the first connecting rod 27 is hinged with the second connecting rod 28, along with the movement of the driven rod 25, the angle between the first connecting rod 27 and the second connecting rod 28 gradually increases, at this time, because the lengths of the first connecting rod 27 and the second connecting rod 28 are not changed, one end of the adjusting plate 19, which is far away from the salient point, gradually rises relative to the rack 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, thereby effectively realizing synchronous change of the collection angle of the dust hood 20 to the waste scraps when the cutting angle of the cutting knife 8 changes.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
