Abstract

The invention relates to the technical field of concrete mixers, and discloses a concrete mixer which comprises a fixing plate. A fixing frame is fixedly mounted on the opposite surface of the fixing plate, and an injection mechanism is fixedly mounted in the fixing frame. According to the concrete mixer, in the rotating process of a transmission mechanism, the fixing plate can be driven to rotate, the fixing plate drives the fixing frame to rotate, then a rotating screw rod is driven to rotate, the rotating screw rod drives a sliding block to move in the fixing frame, and if the situation of oil shortage occurs in the fixing plate, the internal temperature can rise, so that the size of an expansion bag is increased; and the arc-shaped surface of the expansion bag is expanded towards the inner side, then a limiting rod is driven to move towards the inner side to leave a supporting rod, and therefore the supporting rod can extrude a storage chamber in the sliding process at the bottom of a containing plate, lubricating oil in the storage chamber is extruded into a discharging pipe to enter the transmission mechanism, and the effect of automatic lubricating oil injection is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete mixers, in particular to a concrete mixer. Background technique [0002] The concrete mixer consists of a power mechanism connected to the transmission mechanism through a shaft and a roller driven by the transmission mechanism. The roller body is equipped with a ring gear arranged around the drum body, and a gear meshed with the ring gear is arranged on the transmission shaft, which can mix cement, sand and gravel. A machine that mixes aggregate and water to make concrete mixture, and is generally used in the infrastructure industry. [0003] During the use of the concrete mixer, it is necessary to maintain and maintain the body. After mixing, it is not only necessary to clean it, but also to inject lubricating oil into the transmission part of the rotating shaft to ensure that the rotating shaft will not overheat during use. Abnormal sound, but in the process of using the current mixer, the in...
