It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a waste compactor escaping assistance system includes a pusher lifting cylinder 1 and a working multi-way valve 2. The pusher lifting cylinder 1 and the working multi-way valve 2 form a pusher working circuit. The working multi-way valve 2 is connected to the large chamber and the small chamber of the pusher lifting cylinder 1 respectively. The working multi-way valve 2 is used to control the extension and retraction of the pusher lifting cylinder 1, thereby driving the pusher 10 to descend or rise.

[0024] It also includes the pusher lifting circuit and the return oil circuit;

[0025] The pusher lifting circuit is connected between the hydraulic oil tank 8 and the small cavity of the pusher lifting cylinder 1. The pusher lifting circuit is connected to a hydraulic oil filter 7, a hand pump 5, a one-way valve and a manual switching valve 3. The pusher lifting circuit is used to lift the pusher 10 when the pusher working circuit fails and the pusher 10 cannot be lifted.

[0026] The return oil circuit is connected between the hydraulic oil tank 8 and the large cavity of the pusher lifting cylinder 1. A manual switching valve 3 is connected to the return oil circuit. The return oil circuit is used to return the oil in the large cavity of the pusher lifting cylinder 1 to the hydraulic oil tank 8.

[0027] The manual switching valve 3 has a closed state position 3-1 and a normally open state position 3-2. The manual switching valve 3 is normally in the closed state position 3-1. The pusher lifting circuit and the return oil circuit are simultaneously connected to the closed state position 3-1 or simultaneously connected to the normally open state position 3-2.

[0028] It should be noted that the one-way valve used is a common hydraulic component, ensuring the hydraulic oil flows in a designated direction while preventing reverse flow. The hand pump 5 is used to manually pump out the hydraulic oil. The hydraulic oil filter 7 ensures the cleanliness of the incoming oil. The hydraulic oil tank 8 stores the hydraulic oil and is used for oil intake and return.

[0029] In some embodiments, such as Figure 1 , Figure 3 As shown, the piston rod of the pusher lifting cylinder 1 is hinged to the pusher 10, and the cylinder is connected to the frame 9. The working multi-way valve 2 is connected to the pusher lifting cylinder 1 through a hydraulic line to control the oil flow in and out of the large and small chambers of the cylinder. When the working multi-way valve 2 controls the pusher lifting cylinder 1 to extend, the pusher 10 descends. When the working multi-way valve 2 controls the pusher lifting cylinder 1 to retract, the pusher 10 rises.

[0030] In some embodiments, such as Figure 1 , Figure 2 As shown, the manual switching valve 3 is a two-position four-way valve with a locking structure. The manual switching valve 3 is normally in the closed position 3-1, and can be manually switched to the normally open position 3-2 when needed. The manual switching valve 3 can be an MSV13-12 manual push valve.

[0031] In some embodiments, such as Figure 1 As shown, the one-way valve includes one-way valve 4 and one-way valve 6. One-way valve 4 is installed at the outlet end of the hand pump 5, and one-way valve 6 is installed at the inlet end of the hand pump 5. One-way valve 4 and one-way valve 6 control the unidirectional flow of hydraulic fluid from the hydraulic oil tank 8 to the small cavity of the pusher lifting cylinder 1. In some more specific embodiments, the inlet of the hydraulic oil filter 7 is connected to the hydraulic oil tank 8, the outlet of the hydraulic oil filter 7 is connected to the inlet of one-way valve 6, the outlet of one-way valve 6 is connected to the inlet of the hand pump 5, the outlet of the hand pump 5 is connected to the inlet of one-way valve 4, and the outlet of one-way valve 4 is connected to the manual switching valve 3.

[0032] In a second aspect, this utility model also provides a garbage compactor, wherein the garbage compactor is equipped with the aforementioned garbage compactor scrambling assistance system.

[0033] The waste compactor equipped with this waste compactor traction assistance system has two states: the pusher lifting cylinder 1 drives the pusher 10 to descend or rise.

[0034] Normal state: The pusher lifting cylinder 1 and the working multi-way valve 2 constitute the pusher working circuit. Oil enters the large chamber and exits the small chamber. At this time, the pusher lifting cylinder 1 drives the pusher 10 to descend; oil enters the small chamber and exits the large chamber. At this time, the pusher lifting cylinder 1 drives the pusher 10 to rise.

[0035] Manual mode: Due to malfunctions such as no power to the machine or failure of the pusher lifting device, the working multi-way valve 2 is locked, and the normal hydraulic circuit cannot work, requiring manual lifting. Switch the manual switching valve 3 from the closed position 3-1 to the normally open position 3-2 and lock it. Pump the hydraulic oil from the hydraulic oil tank 8 through the hand pump 5, and let it pass through the hydraulic oil filter 7, one-way valve 2 6, hand pump 5, one-way valve 4, and manual switching valve 3 in sequence, entering the small chamber of the pusher lifting cylinder 1. The return oil from the large chamber of the pusher lifting cylinder 1 passes through the manual switching valve 3 and returns to the hydraulic oil tank 8, ultimately driving the pusher 10 to lift. After lifting to the target position, switch the manual switching valve 3 from the normally open position 3-2 to the closed position 3-1 and lock it. At this time, the pusher 10 is locked, which is conducive to towing operations and greatly reduces the difficulty of transportation or towing away.

[0036] This utility model's waste compactor scrambling assistance system eliminates the need for external equipment in the absence of a power source. The pusher of the waste compactor can be lifted manually, ensuring that the waste compactor is not affected by the pusher when scrambling. The system is simple in structure, highly reliable, and easy to implement.
