Abstract

The invention discloses a lubricating system for a concrete stirring main machine and the concrete stirring main machine, and relates to the technical field of engineering machines, which solve the technical problem that the working environment for shaft-end sealing is not stable to cause a poor shaft-end sealing effect in the prior art. The lubricating system comprises a controller, a lubricating circuit control switch, a lubricating oil pump, a power supply and an oil filling pipe, wherein a feeding valve of the stirring main machine can send a feeding signal to the controller when in an opened state; and a detector for opening-closing state of a concrete unloading door of the stirring main machine sends a concrete unloading door opening signal to the controller when the concrete unloading door of the stirring main machine is in an opened state. The concrete stirring main machine comprises an electric concentrated lubricating system which is the lubricating system for the concrete stirring main machine provided by the invention. The invention is used for improving the sealing performance of the shaft-end sealing.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a lubrication system device for a concrete mixing main engine and a concrete mixing main engine provided with the lubrication system for a concrete mixing main engine. Background technique [0002] The twin-shaft concrete mixer main engine is a kind of mechanical equipment that mixes different raw materials such as aggregate, binder and water into ready-mixed concrete. It has two mixing main shafts and is placed parallel to the horizontal plane. [0003] When the twin-shaft concrete mixing main engine is in working state, due to the rotation of the mixing shaft, there must be a movement gap at both ends of the mixing tank. This gap becomes the invasion part of concrete cement mortar. If the protection is not proper, the concrete will seep into the mixing tank along this part. cylinder exterior. In order to solve this problem, the shaft end seal has become a key tec...
