[0037] Referring to Figure 3The transmission mechanism further comprises a second electric hydraulic cylinder 10 and a triangular block 12, the cross section of the triangular block 12 is isosceles triangle, two strip-shaped sliding holes 11 are slidably connected to two side walls of the triangular block 12, so that driving the second electric hydraulic cylinder 10 can drive the triangular block 12 to slide, thereby controlling the sliding of the two L-shaped resistance rods 13, and the extension and retraction of the second electric hydraulic cylinder 10 can realize the movement of the two L-shaped resistance rods 13 and the rack 14 at the end, and further realize the left and right sliding of the L-shaped resistance rod 13 and the rotation of the gear 15 driven by the rack 14;

[0039] The output end of the first electric hydraulic cylinder 6 is provided with a supporting and crushing mechanism for supporting and crushing the plastic pipe 8 to be cut, the supporting and crushing mechanism comprises a telescopic cylinder 7 and a plurality of lifting blades 17 arranged circumferentially on the side wall of the telescopic cylinder 7 and used for extruding the inner wall of the plastic pipe 8 to be cut, so that the originally complete plastic pipe 8 to be cut can be broken into several pieces from the inner wall, thereby effectively solving the problem that the existing crushing method produces a large amount of small plastic particles, which affects the subsequent collection and causes environmental pollution, and the plastic pipe is crushed into pieces of complete and same shape, so that the subsequent collection is facilitated.

[0040] The supporting and crushing mechanism further comprises an oil cavity 18, a pressing rod 19 and a first piston 23, the output end of the first electric hydraulic cylinder 6 is fixed with the pressing rod 19, so that the first electric hydraulic cylinder 6 can drive the pressing rod 19 to move and complete the crushing of the plastic pipe 8 to be cut, the oil cavity 18 is coaxially arranged at one end of the telescopic cylinder 7, the first piston 23 slides in the oil cavity 18, the first piston 23 is fixed with the pressing rod 19, and it needs to be noted that when the first electric hydraulic cylinder 6 drives the pressing rod 19 to drive the first piston 23 to slide in the oil cavity 18, the first piston 23 drives the telescopic cylinder 7 to move in the initial state, and the first piston 23 does not slide in the oil cavity 18.

[0041] It needs to be explained that the oil cavity 18 is filled with oil, and when the pressing rod 19 moves, the oil cannot flow at this time, so that the pressing rod 19 drives the telescopic cylinder 7 to move through the first piston 23, and the position of the telescopic cylinder 7 is changed;

[0046] It needs to be explained that, as shown in Figure 5 After the plug rod 22 is squeezed into the telescopic cylinder 7, the second piston 24 originally blocking the first communication oil hole 25 moves away from the piston moving groove 27, so that the first communication oil hole 25 and the oil cavity 18 which are not connected are connected, at this time, the oil flows, so that the pressing rod 19 drives the oil in the oil cavity 18 to move through the first piston 23, the position of the oil in the oil cavity 18 is changed, and finally the lifting blade 17 in the blade lifting groove 16 is extended, and the plastic pipe 8 to be cut is crushed;

[0048] After the crushing is completed, the telescopic cylinder 7 retreats, at this time the pressing rod 22 drives the second piston 24 to reset into the piston movable slot 27 under the action of the second reset spring 28, and then reblocks the first communication oil hole 25, but at this time, due to the existence of the first reset spring 20, the first piston 23 is driven to slide in the oil cavity 18, and then the oil liquid originally flowing into the blade lifting groove 16 is drawn back to the oil cavity 18 along the one-way valve 29, so that the originally extended lifting blade 17 is retracted into the telescopic cylinder 7, facilitating the subsequent crushing.

[0049] The working principle of the present application is as follows: the plastic pipe 8 to be cut falls on the rotating flap 3 along the discharging plate 2, the cross section of the plastic pipe 8 to be cut is attached to the discharging plate 2 and falls on the rotating flap 3, and the plastic pipe 8 to be cut rolls to the lowest part of the arc-shaped groove 4, facilitating the subsequent clamping of the two clamping half plates 9 on the plastic pipe 8 to be cut.

[0050] Driving the second electric hydraulic cylinder 10 can drive the triangular block 12 to slide, complete the control of the sliding of the two L-shaped abutting rods 13, and the moving triangular block 12 not only drives the two L-shaped abutting rods 13 to slide, but also drives the rack 14 to move and drives the gear 15 to complete the rotation of the rotating flap 3, so that the plastic pipe 8 to be cut after the crushing and cutting can fall into the crushing box 1, wherein the pressing rod 19 drives the first piston 23 to complete the lifting of the lifting blade 17 in the blade lifting groove 16 driven by the oil liquid, and the inner wall of the plastic pipe 8 to be cut is abutted, so that the plastic pipe 8 to be cut is completely crushed into several pieces of the same size from the abutting and crushing of the inner wall of the plastic pipe 8 to be cut.
