When the piston rod 7 is extended to the limit position, the air hole 17 is located at the expansion hole, and the air hole 17 is communicated with the air outlet passage 16. When the piston rod 7 is retracted to the limit position, the air hole 17 is located in the first chamber 9, and the air hole 17 is communicated with the air inlet passage 15.

[0023] In order to facilitate the discharge of waste, in the present embodiment, the waste slide plate 1 is arranged at an angle. Specifically, the waste slide plate 1 is fixed to the upper end surface of the support plate 3, and the waste slide plate 1 is parallel to the support plate 3. The front end of the support plate 3 is hinged to the front end of the sliding plate 2, and the rear end of the support plate 3 is supported by the angle adjustment block 10. The left and right sides of the support plate 3 are provided with downwardly extending side panels 11, and the side panels 11 are provided with a plurality of limiting grooves, and the plurality of limiting grooves are spaced apart along the front and rear directions. The left and right end heads of the angle adjustment block 10 are provided with limiting threaded holes, and the limiting rod 12 passes through the limiting groove and is threadedly connected to the limiting threaded hole.

[0024] Specifically, in the present embodiment, an outlet joint 13 is connected to the cylinder body 4 at the outlet of the outlet passage 16, and an inlet joint 14 is connected to the cylinder body 4 at the inlet of the inlet passage 15, and flow control valves are installed on both the inlet joint 14 and the outlet joint 13; by adding a flow control valve, the speed of air inlet and outlet can be adjusted, thereby adjusting the speed of extension and retraction of the piston rod 7.

[0025] In this embodiment, there are two air holes 17, one at the front end of the piston rod 7 and one at the rear end of the piston rod 7. During the entire working process, the air hole 17 located at the rear end of the piston rod 7 is mainly responsible for the air hole 17. The reason why an air hole 17 is added to the front end of the piston rod 7 is to facilitate the adjustment of the operating speed. The air hole 17 located at the front end of the piston rod 7 can be connected to the air outlet channel 16 in advance, so that the operating speed can be adjusted as needed.

[0026] In order to reduce noise, in this embodiment, a muffler is also installed on the air outlet connector 13.

[0027] In order to improve the sealing performance and ensure the reliable operation of the automatic waste discharge mechanism, a first sealing ring 20 is installed at the rear end of the piston rod 7, and the rear end of the first sealing ring 20 is attached to the piston 6; a second sealing ring 21 is installed at the front end of the piston rod 7, and when the piston rod 7 is in a retracted state, the second sealing ring 21 is attached to the cylinder body 4.

[0028] In order to facilitate production and manufacturing, in this embodiment, the piston 6 and the piston rod 7 are an integrated structure.

[0029] Initially, the piston rod 7 is in a free state. During operation, when the air hole 17 at the rear end of the piston rod 7 has not entered a sealed state, that is, when the air hole 17 at the rear end of the piston rod 7 is not in the second chamber, the gas entering from the air inlet channel 15 enters the first chamber 9 at the rear end of the piston 6 through the air hole 17 at the rear end of the piston rod 7, the first air channel 18, and the second air channel 19, thereby pushing the piston 6 forward, thereby driving the piston rod 7 forward. When the piston rod 7 advances to the exhaust position, that is, the air hole 17 at the rear end of the piston rod 7 is closed. At the expanded hole, at this time, the air hole 17 at the front end of the piston rod 7 enters a sealed state, and the gas in the first chamber 9 at the rear end of the piston 6 is discharged through the second air passage 19, the first air passage 18, the air hole 17 at the rear end of the piston rod 7, and the expanded hole into the air outlet passage 16, so that the air pressure in the first chamber 9 at the rear end of the piston 6 is reduced, thereby causing the piston rod 7 to move backward until the air hole 17 at the rear end of the piston rod 7 is connected to the air intake passage 15 to realize air intake, and this reciprocating cycle is repeated to realize the reciprocating extension and contraction of the piston rod 7.

[0030] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
