Embodiment 1

[0025] please if Figure 1 to Figure 2 as shown, figure 1 The schematic diagram of the tailgate hydraulic system of the mobile garbage compactor provided in this embodiment, figure 2 The structural diagram of the hydraulic system of the tailgate of the mobile garbage compression box provided in this embodiment, the hydraulic system of the tailgate of the mobile garbage compression box provided in this embodiment includes a main oil circuit 1 communicating with the oil inlet, and is used to make the tailgate The first oil passage 31 for contracting the oil cylinder 2 and the second oil passage 32 for extending the tailgate cylinder 2, the first oil passage 31 communicates with the main oil passage 1, the second oil passage 32 communicates with the main oil passage 1, and the second oil passage 32 communicates with the main oil passage 1. The second oil circuit 32 communicates with the oil return port, and the main oil circuit 1 is provided with a one-way valve 4, and the tail...

Embodiment 2

[0034] please if image 3 As shown, the difference between the tailgate hydraulic system of the mobile garbage compactor provided in this embodiment and the first embodiment is that,

[0035] The tailgate hydraulic system of the mobile garbage compression box provided in this embodiment is provided with a three-way valve 84 on the second oil circuit 32, and an oil return oil circuit 9 is arranged on the three-way valve 84, and the oil return circuit 9 is connected to the oil return circuit. The mouth is connected.

[0036] Wherein, the three-way valve 84 is preferably a three-way stop valve or a three-way ball valve.

[0037] When the mobile garbage compression box compresses the garbage, because the three-way stop valve is blocked, the hydraulic oil entering through the main oil circuit 1 does not flow to the second oil circuit 32, but only flows to the first oil circuit 31, and then passes through the first oil circuit. The road 31 flows to the rod cavity of the tailgate o...

Embodiment 3

[0040] please if Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the tailgate hydraulic system of the mobile garbage compactor provided by this embodiment is also provided with an energy storage oil circuit 6, and one end of the energy storage oil circuit 6 is connected to the main oil circuit 1 The other end of the accumulator 6 communicates with the oil return port. The accumulator 5 is arranged on the energy storage oil passage 6, and the overflow valve 7 is arranged on the energy storage oil passage 6, and the overflow valve 7 is arranged on the energy storage oil passage 6. Between device 5 and the oil return port.

[0041] In this embodiment, a third cut-off valve 83 is provided on the first oil passage 31. When compressing the garbage, the first cut-off valve 81 is closed, and the hydraulic oil coming in from the oil inlet cannot enter the second oil passage 32. , directly enters the first oil passage 31, because the first oil passag...

Abstract

The invention discloses a movable trash compression box tail door hydraulic system. The movable trash compression box tail door hydraulic system comprises a main oil way communicating with an oil inlet, a first oil way used for a tail door oil cylinder to shrink, and a second oil way used for the tail door oil cylinder to extend. The first oil way communicates with the main oil way; the second oil way communicates with the main oil way and communicates with an oil returning port; and the main oil way is provided with a check valve. The movable trash can tail door hydraulic system is further provided with an energy accumulator, and therefore when the tail door oil cylinder shrinks, pressure oil can be stored, and when a tail door is opened, the energy accumulator can provide the pressure oil so that the tail door oil cylinder can extend to act. By means of the movable trash compression box tail door hydraulic system, the tail door of a movable trash compression box can be opened and closed under the conditions that no power source is needed and other pressure oil does not exist, the system is environment-friendly, fault points are reduced, and other power sources do not need to be added.

Description

technical field [0001] The invention belongs to the technical field of garbage disposal equipment, and in particular relates to a tailgate hydraulic system of a mobile garbage compression box. Background technique [0002] The garbage management in cities is often to set up garbage bins in each residential area, and people put domestic garbage into the garbage bins, and then the garbage trucks regularly go to each garbage collection point to collect the garbage in the garbage bins. In order to increase the loading capacity, the garbage will be compressed when it is loaded into the garbage bin. This mobile garbage bin with compression function is a mobile garbage compression bin. [0003] At present, in the working condition of compressing garbage, the mobile garbage compression boxes in China must carry out the two functions of feeding and compressing, so as to compress the garbage, increase the density of garbage, and improve the efficiency of garbage transfer. When compre...
