[0023] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0024] Referring to Figure 1 Fig. 1, the prior art structure schematic diagram provided by the utility model, a commercial concrete mixer with stripping ring, including mixer shell 1, the inside rotating connection of mixer shell 1 has rotating shaft 2, is equipped with multiple groups of stirring blade 3 on rotating shaft 2, when using, pour the material into the inside of mixer shell 1, then drive rotating shaft 2 to rotate through the driving device set up on mixer shell 1, simultaneously, rotating shaft 2 drives multiple groups of stirring blade 3 to rotate and stirs the material, in the stirring, due to the adhesion of material and the accumulation on the surface of rotating shaft 2, the phenomenon of shaft holding appears, influence the use of rotating shaft 2, therefore, the stripping ring body 4 for preventing material holding shaft is movably sleeved on rotating shaft 2, and stripping ring body 4 is detachably connected, is convenient for installing on rotating shaft 2, however, due to the block of stirring blade 3 set up on rotating shaft 2, adjacent two stripping ring bodies 4 cannot completely move to the state of adhesion, and the position of being blocked by stirring blade 3 on the rotating shaft is prone to appear cleaning dead angle, such as Figure 1 A area position in Fig. 1, cannot be cleaned;

[0025] According to the above problems, the utility model makes the following improvements, as shown in Figures 2-6 Fig. 2, stripping ring body 4 is equipped with cleaning part 5, along with rotating shaft 2 drive stripping ring body 4 to rotate, stripping ring body 4 will move back and forth between adjacent two stirring blades 3, when stripping ring body 4 approaches stirring blade 3, the cleaning part 5 on it can extend to the dead angle position A on the rotating shaft 2 blocked by stirring blade 3, and the material is cleaned, further reduce the possibility of material holding shaft, to improve the comprehensiveness of material cleaning.

[0026] Specifically, referring to Figure 2 Fig. 1, Figure 4 Fig. 2 and Figure 6 Fig. 3, as the first embodiment of the utility model, multiple clamping grooves 6 are equidistantly set up on stripping ring body 4, clamping groove 6 can be designed according to the shape of stirring blade 3, at this time, cleaning part 5 is the part between adjacent two clamping grooves 6, when stripping ring body 4 approaches stirring blade 3, clamping groove 6 can be attached with the stem of stirring blade 3, cleaning part 5 can move synchronously with stripping ring body 4 to the position of rotating shaft 2 blocked by stirring blade 3, thereby cleaning the material of the part of rotating shaft 2 blocked by stirring blade 3, reduce the possibility of material adhesion.

[0027] Referring to Figure 3 , Figure 5 and Figure 7 , as a second embodiment of the present application, the cleaning part 5 can also be a plate structure provided on the stripper ring body 4, and the length of the cleaning part 5 is greater than the diameter of the rod body of the stirring blade 3, and the length extension direction of the cleaning part 5 is parallel to the axial direction of the rotating shaft 2. When the stripper ring body 4 rotates to drive the cleaning part 5 to approach the stirring blade 3, the cleaning part 5 can move to the A part of the rotating shaft 2 blocked by the stirring blade 3 to clean the dead angle position.

[0028] Compared with the cleaning of the A part by the cleaning part 5 in the first embodiment, since the clamping groove 6 on the stripper ring body 4 can only wrap the rod body of the stirring blade 3 on one side, it can only clean the part of the rotating shaft 2 blocked by the stirring blade 3, and cannot completely cover the dead angle position. If complete cleaning of the dead angle position is required, the stripper ring bodies 4 on both sides of the stirring blade 3 need to move towards the stirring blade 3 and abut against each other, but when the rotating shaft 2 drives the stripper ring body 4 to rotate, this probability is small. Therefore, generally, one stripper ring body 4 drives the cleaning part 5 to clean, and then when the stripper ring body 4 on the other side of the stirring blade 3 moves to the other side of the stirring blade 3, the other side of the dead angle position is cleaned. The cleaning part 5 in the second embodiment is in the form of a plate, and when the stripper ring body 4 is blocked by the stirring blade 3, the plate-shaped cleaning part 5 can directly extend to the A area for cleaning, which is more efficient. When the rotating shaft 2 drives the stripper ring body 4 to move, the adjacent two cleaning parts 5 can touch each other, so that the stirring effect of the material can be further improved by cooperating with the stirring blade.

[0029] Referring to Figures 2-7 , in order to improve the cleaning efficiency, the number of cleaning parts 5 is multiple, and the multiple cleaning parts 5 are respectively located at the two ends of the stripper ring body 4. When the stripper ring body 4 moves with the rotating shaft, the reciprocating movement of the stripper ring body 4 can drive the cleaning parts 5 at the two ends to clean the dead angle positions on the rotating shaft 2 at the two ends of the stripper ring body 4.

[0030] In order to improve the cleaning efficiency of the A position, the cross section of the cleaning part 5 is arc-shaped. When the arc-shaped cleaning part 5 moves to the A position, the curvature can match the circumferential shape of the rotating shaft 2 to realize surface contact. In the process of rotating the stripper ring body 4, the cleaning part 5 can better abut against the surface of the rotating shaft 2, and the material attached to the rotating shaft 2, especially the material close to the A position, can be cleaned more thoroughly, reducing the phenomenon of material sticking to the shaft.

[0031] Referring to Figures 2-7As shown, further, the cleaning part 5 is provided with a plurality of cleaning protrusions 7, when the cleaning protrusions 7 act on the material, for scraping the material, can penetrate into the agglomerates formed by the material, effectively destroy the structure of the agglomerates, so that the agglomerates are dispersed, for the material in the gap and corner, can ensure that these areas will not have material residues, and the cleaning protrusions 7 also change the form of the surface of the cleaning part 5, so that the material is difficult to form a continuous, large-area adhesion layer on the cleaning part 5, when the material contacts the cleaning part 5, it will be dispersed by the cleaning protrusions 7, and it is difficult to lay flat on the surface, thereby reducing the possibility of material blocking the cleaning part 5, ensuring the normal work of the cleaning part 5.
