Description

Technical Field

[0001] The invention relates to the technical field of building tool cleaning, and in particular to a device for cleaning attachments of building tools. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. In the process of building construction, a variety of construction tools are required, including trowels, concrete mixers, horse stools, steel tape measures, etc. that are frequently used by bricklayers. When these tools are used, it is easy for some debris such as concrete to be attached, especially concrete mixers. Since they mix concrete in the mixing drum, there is still a certain amount of concrete inside the mixing drum after each use. If the concrete inside is not cleaned quickly, it will solidify inside it, causing damage to the mixing drum. Therefore, it is necessary to use a cleaning device to clean the concrete inside the mixing drum.

[0003] In the prior art, the existing method for cleaning the concrete inside the mixing barrel is to manually use a large amount of water to flush the concrete residue inside the mixing barrel, but this cleaning method consumes a large amount of water resources and cannot effectively clean the concrete attached to the inner wall of the mixing barrel. Therefore, the Chinese patent with publication number CN 115464776 A discloses an easy-to-clean mixer, in which a cleaning device is arranged inside. By starting a driving motor to drive the rotating shaft to rotate, a scraper is used to scrape off the slag on the inner wall of the machine body, thereby cleaning the inner wall of the machine body, which is convenient for cleaning the mixer. At the same time, by arranging an annular pipe and a flushing head inside the machine body, water can be conveniently supplied to the annular pipe through an external water pump, so that the flushing head flushes the inner wall of the machine body, with less water consumption, and the scraper can be used to improve the cleaning effect of the inside of the machine body. However, when the scraper of the device scrapes off the slag, part of the concrete will adhere to the scraper, which is not easy to be flushed by water flow, and affects the normal use of the mixer after solidification.
