Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixers, in particular to a cleaning device for a compulsory concrete mixer. Background Technique

[0002] Compulsory concrete mixers are widely used in the field of concrete mixing. The existing double-horizontal-shaft compulsory concrete mixer is composed of two mixing shafts horizontally arranged in the machine body, and mixing paddles are installed on the mixing shafts, which can well solve the problem of aggregate agglomeration in cement. Therefore, the mixing quality is good and the efficiency is high. However, when the concrete mixer is in use, due to the strong adhesiveness of concrete, it is time-consuming and laborious to clean the mixer.

[0003] After retrieval, a Chinese patent discloses a cleaning device for a compulsory concrete mixer (authorization publication number CN217169096U), which includes a support plate and a mixing barrel. The mixing barrel is rotatably installed at the top of the support plate. A support block is fixedly installed at the top of the support plate, a water pump is fixedly installed at the top of the support block, a fixed cylinder is fixedly installed at the top of the support block, a water delivery pipe is sleeved in the fixed cylinder, one end of the water delivery pipe is communicated with the water outlet pipe of the water pump, and a plurality of spray heads distributed in an array are threadedly connected to the side wall of the other end of the water delivery pipe. Although this patented technology has the function of scraping the concrete adhered to the inner wall of the mixer and the function of flushing the concrete adhered to the inner wall of the mixer.

[0004] However, there are still some disadvantages in the actual use of the above device. The more obvious one is that the overall structure of the above cleaning device for a compulsory concrete mixer is a fixed design, resulting in that the cleaning device cannot be taken out of the compulsory concrete mixer, and thus the cleaning operation cannot be carried out on other concrete mixers. Therefore, it is necessary to order an additional cleaning device for use, which not only increases the cost but also reduces the applicability of the device. Content of the Utility Model

[0005] In view of the above problems existing in the prior art, the main purpose of the present utility model is to provide a cleaning device for a compulsory concrete mixer.
