[0061] Based on this, the utility model embodiment provides a kind of pneumatic system and cattle driving device of cattle driving device, and the following is specifically described by embodiment.

[0062] Example one

[0063] The utility model discloses an air drive system of a cattle driving device, referring to Figure 1 Including air source subassembly, air control subassembly, reversing valve 12, three -way air control valve 20, at least one air cylinder 21 and air drive motor 16,

[0071] Air control subassembly can control reversing valve 12's actuating mechanism and three -way air control valve 20's actuating mechanism action, to open or close reversing valve 12's first passageway or second passageway, and, open three -way air control valve 20's first passageway or second passageway, reversing valve 12's first passageway is first air inlet to first air outlet, reversing valve 12's second passageway is second air inlet to second air outlet, three -way air control valve 20's first passageway is first air inlet to air outlet, three -way air control valve 20's second passageway is second air inlet to air outlet.

[0072] In the embodiment, compressed air from air source subassembly can be accessed air control subassembly, three -way air control valve 20 and reversing valve 12, thereby providing power source for air cylinder 21 and air drive motor 16.

[0073] In optional implementation, referring to Figure 1 The first pressure regulating valve 3 is arranged between the air source subassembly and the air control subassembly, and the air source pressure can be adjusted to the pressure required by the air control subassembly through the first pressure regulating valve 3, so as to ensure the safety of the pipeline and the normal work of the air control subassembly.

[0074] In an optional embodiment, a second pressure regulating valve 4 is provided between the air source assembly and the first air inlet of the reversing valve 12. The second pressure regulating valve 4 can adjust the air source pressure to the pressure required by the pneumatic motor 16, thereby ensuring pipeline safety and the normal operation of the pneumatic motor 16. The first air outlet of the reversing valve 12 is connected to the forward rotation port of the pneumatic motor 16. Compressed air, after being regulated by the second pressure regulating valve 4, can reach the forward rotation port of the pneumatic motor 16 through the first passage of the reversing valve 12, thereby driving the motor to rotate forward. The pneumatic motor 16 is connected to the frame of the cattle-driving device; when the pneumatic motor 16 rotates forward, it drives the frame forward.

[0075] In an optional implementation, refer to Figure 1 As shown, a third pressure regulating valve 5 is installed between the air source assembly and the second air inlet of the reversing valve 12. This valve adjusts the air source pressure to the level required by the pneumatic motor 16, ensuring pipeline safety and the normal operation of the pneumatic motor 16. The second air outlet of the reversing valve 12 connects to the reverse port of the pneumatic motor 16. Compressed air regulated by the third pressure regulating valve 5 can reach the reverse port of the pneumatic motor 16 via the second passage of the reversing valve 12, thus driving the motor to reverse. The reverse transmission of the pneumatic motor 16 causes the vehicle frame to move backward.

[0076] In an optional implementation, refer to Figure 1 As shown, a fourth pressure regulating valve 6 is installed between the air source assembly and the first air inlet of the three-way air control valve 20. The fourth pressure regulating valve 6 can adjust the air source pressure to the pressure required for the cylinder 21 to extend, thereby ensuring pipeline safety and the normal operation of the cylinder 21. The air outlet of the three-way air control valve 20 is connected to the working port of the cylinder 21. Compressed air, after being regulated by the fourth pressure regulating valve 6, can reach the working port of the cylinder 21 through the first passage of the three-way air control valve 20, thereby driving the cylinder 21 to extend.

The outlet of the three-way air control valve 20 connects to the working port of the cylinder 21. Compressed air regulated by the fifth pressure regulating valve 7 reaches the working port of the cylinder 21 via the second passage of the three-way air control valve 20, providing back pressure to the tipping gate and preventing it from falling rapidly under gravity and injuring the cattle.

[0078] Furthermore, refer to Figure 1As shown, the number of the air cylinders 21 can be set to two. The two air cylinders 21 are arranged at the two side ends of the turnover door, and the working ports of the two air cylinders 21 are connected to the air outlet of the three-way reversing valve 12, so that the turnover door is uniformly stressed when the turnover door is opened or lowered.

The air inlet of the travel switch 14 is communicated with the first air outlet of the reversing valve 12, and the air outlet of the travel switch 14 is communicated with the actuator of the two-way air control valve 13. The actuator of the two-way air control valve 13 can open the two-way air control valve 13 under the action of pressure, so that the compressed air can pass through the two-way air control valve 13 to the forward rotation port of the air motor 16. Further, the travel switch 14 is arranged below or beside the turnover door, and can abut against the travel switch 14 when the turnover door is lowered, so as to open the travel switch 14 and open the two-way air control valve 13 to drive the air motor 16 to rotate forward, drive the vehicle frame to move forward, and realize the signal interlocking of the turnover door and the vehicle frame, that is, only when the turnover door is completely lowered, the vehicle frame can move forward, effectively preventing the cattle from being injured during the lowering of the turnover door, and improving the safety of the cattle driving device.
