Concrete mixer is an important engineering machinery, which is widely used in construction and transportation. Because the construction environment is complex and changeable, the equipment works continuously for a long time, which is prone to wear and failure. It is the basic work for the operators to know how to maintain the equipment before work.

混凝土搅拌机是一种将水泥、沙石和水等材料混合并搅拌成为混凝土混合料的机械，其结构主要包括加料结构、搅拌仓、卸料结构、原动机、传动结构、供水结构、机架和支撑装置组成。在混凝土搅拌机的工作过程中，必选做到以下三点：定期检查叶片和搅拌机罐体之间的间隙。

Concrete mixer is a kind of machine that mixes cement, sand, water and other materials to make concrete mixture. Its structure mainly includes feeding structure, mixing bin, discharging structure, prime mover, transmission structure, water supply structure, frame and supporting device. In the working process of concrete mixer, it is necessary to do the following three points: regularly check the gap between the blade and the mixer tank.

根据搅拌机的使用情况，制定合理的检修周期，使用频率越高，检修周期越短，使用周期较低，可以适当延长，防止砂浆滴入到间隙中对混凝土搅拌机造成损坏；定期检查轴端注油的情况。

According to the usage of the mixer, a reasonable maintenance period is formulated. The higher the usage frequency is, the shorter the maintenance period is, and the lower the usage period is, which can be appropriately extended to prevent the mortar from dropping into the gap and causing damage to the concrete mixer; Regularly check the oil filling at the shaft end.

轴端容易受到渗 透砂浆的影响，要定期检查轴端的注油装置，并及时清理轴承、轴套部位的水泥砂浆，保证搅拌机的寿命；定期检查除尘器的状况。集中除尘器的滤清或布袋需要经常进行清洗，如果除不干净要及时更换。除此之外，要注意操作规程，不可违章操作。

The shaft end is easily affected by the permeable mortar, so the oil filling device at the shaft end should be checked regularly, and the cement mortar at the bearing and shaft sleeve should be cleaned in time to ensure the service life of the mixer; Check the condition of the dust collector regularly. The filter or bag of the centralized dust collector needs to be cleaned frequently. If it is not clean, it should be replaced in time. In addition, we should pay attention to the operating procedures, not illegal operation.

在生产过程中，为了保证工程机械设备充分、有用地发挥作用，对设备的保养、维护就变得关重要，但机械维修和维护并不是一种简单更换零部件的机械重复性工作，而是要通过合理的维修和维护措施，使机械设备在保证其工作性能的基础上，具有较好的可靠性、耐用性。

In the production process, in order to ensure that the construction machinery and equipment play a full and useful role, the maintenance of the equipment becomes very important, but the mechanical repair and maintenance is not a simple mechanical repetitive work of replacing parts, but through reasonable repair and maintenance measures, the mechanical equipment has better reliability and reliability on the basis of ensuring its working performance Durability.
