The implementation column is implemented like this:

work process:

The concrete material to be stirred is sent into the mixing tank 2 through the feed port 21 provided on the mixing tank 2, and the driving motor 3 drives the mixing assembly 31 to run, and the concrete material is stirred in the mixing tank 2, and the mixing Stop the stirring work after completion, and then open the valve on the discharge port 22 to discharge the stirred concrete. Because the concrete is easy to adhere, there is concrete adhered to the inner wall of the mixing bucket 2. At this time, the second motor 5 operates, and its drive The bevel gear 51 drives the drive ring 6 to rotate through the inclined gear surface 61 meshing with it and is located on the drive ring 6, and the drive ring 6 drives the scraper bar 62 to rotate. Since the scraper bar 62 has a vertical section and an inclined section, The mixing tank 2 is cylindrical and has a round bucket-shaped bottom, so the scraper rod 62 forms no dead angle conflict with the inner wall of the mixing tank 2, and can completely hang down the concrete adhered to the inner wall of the mixing tank 2, and the material can be removed from the discharge port 22. Discharge ensures that the concrete is not easy to waste, and at the same time solves the problem that the concrete solidification affects the use of equipment.

working principle:

The drive motor 3 is connected to the stirring rod in the stirring assembly 31, and the stirring rod is welded with stirring blades, so the driving motor 3 drives the stirring assembly 31 to rotate in the mixing bucket to complete the stirring operation.

Further explanation: the second motor 5 drives the bevel gear 51 to rotate, the bevel gear 51 meshes with the inclined gear surface 61 on the drive ring 6, and the slide rail 62 provided on the drive ring 6 is fixed to the mixing bucket 2 The connected slider 23 is movably connected, and the drive ring 6 is coaxial with the mixing bucket 2, so the driving ring 6 rotates in the mixing bucket 2 under the positioning of the slider 23 and driven by the second motor 5, Thus, the scraper rod 62 fixedly connected to the lower end of the drive ring 6 follows the drive ring 6 to rotate in the mixing bucket 2. Since the vertical section of the scraper rod 62 collides with the inner wall above the bottom of the mixing bucket 2, The inclined section is in contact with the inner wall of the round bucket-shaped bottom of the mixing bucket 2, and the coagulation on the inner wall of the mixing bucket 2 can be completely hung down. The support frame 63 connected to the inclined section of the scraper rod 62 is movably connected through the rotating shaft seat. On the stirring rod of the stirring assembly 31, it is used to fix the scraper rod 62 so that it can closely touch the inner wall of the mixing bucket 2 during operation. Since the support rod 62 is movably connected with the stirring rod of the stirring assembly 31 through the rotating shaft seat, Therefore, the rotation of the scraper rod 62 is not affected.

It is further explained that: the annular cover plate 4 covers the drive ring 6 and the bevel gear 51 and does not interfere with each other, so the splash generated in the mixing bucket 2 during the mixing of concrete will not fall into the drive ring 6 With the bevel gear 51, the operation of the cleaning mechanism 7 is guaranteed. At the same time, the annular cover plate 4 is clamped on the inner wall of the mixing tank 2, and the scraper rod 62 is located outside the annular cover plate 4, so the annular cover plate 4 is not easy to fall off, and does not Hinder the drive ring 6 from driving the scraper bar 62 to clean up.
