Embodiment 7

As shown in FIG. 5 and FIG. 6 , this embodiment provides a working machine 200 including a chassis 220 , the turret structure in any of the above embodiments, and two hydraulic systems 210 . The turret structure is disposed on the chassis 220 , and the chassis 220 can play a supporting role in the working machine 200 . Further, the two oil tanks of the turret structure form the oil storage tanks of the two hydraulic systems 210 respectively, that is, the two hydraulic systems 210 are supplied with oil through one oil tank respectively, which can separate the hydraulic oil used for the different hydraulic systems 210, which is beneficial to Improves overall fluid life and reduces maintenance costs.

In another embodiment, the working machine 200 is specifically a concrete pump truck. The concrete pump truck includes a pumping system 211 and a boom system 212. Through the cooperation of the pumping system 211 and the boom system 212, the concrete pump truck can deploy material distribution operations. . Further, the two hydraulic systems 210 provide power for the pumping system 211 and the boom system 212 respectively. In the concrete pump truck, the pumping system 211 and the mechanical boom have different degrees of pollution to the hydraulic oil under different working conditions. By separating the oil, it is beneficial to improve the cleanliness and service life of the overall oil.

According to the embodiments of the turret structure and the working machine proposed in the present application, the fuel tank and the turret body are integrally formed, or the fuel tank is arranged in the fuel tank in a nested structure, rather than directly installing the two independent tanks on the turret In terms of the method on the body, the space utilization rate is effectively improved, which is conducive to optimizing the overall structural arrangement of the equipment, reducing the overall weight of the equipment, so as to meet the strict requirements of overweight regulations. In addition, the hydraulic oil used for different hydraulic systems can be separated, which is beneficial to improve the service life of the whole oil and reduce the maintenance cost.
