The inner wall at one end is sleeved with a second pulley 9, a transmission rod 11 is fixedly connected to the center of the second pulley 9, a slapping plate 12 is fixedly connected to one side of the bottom of the transmission rod 11, and the material of the slapping plate 12 is rubber, an annular plate 13 is fixedly connected to the bottom of the mixing cylinder 4, a side plate 14 is fixedly connected to the side of the annular plate 13 close to the slapping plate 12, a feed port 15 is fixedly connected to the top of the mixing cylinder 4, and the feed port 15 is funnel-shaped, a fixed block 10 is fixedly connected to one side of the mixing cylinder 4, and the transmission rod 11 is rotatably connected to the inner wall of the fixed block 10.
[0024] In order to solve the problem that the mixer is prone to blockage, when the road surface needs to be paved, the material can be put into the mixing cylinder 4 through the feed port 15, and the rotating motor 5 is started. The rotating motor 5 drives the stirring rod 6 to rotate. When the stirring rod 6 rotates, the material will be stirred evenly. After the material is stirred evenly, the valve can be opened to allow the material to fall downward through the bottom of the mixing cylinder 4, so that the road surface can be paved. When the stirring rod 6 rotates, it will drive the first pulley 7 set on the outer wall to rotate. When the first pulley 7 rotates, it will drive the transmission belt 8 to rotate. At the same time, the rotation of the transmission belt 8 can drive the second pulley 9 to rotate. When the second pulley 9 rotates, the transmission rod 11 and the slapping plate 12 at the bottom can be driven to rotate together. When the slapping plate 12 rotates, it will hit the side plate 14 on one side, and make the side plate 14 and the annular plate 13 vibrate.

Since the material of the slapping plate 12 is rubber, after the slapping plate 12 hits the side plate 14, the slapping plate 12 will pass over the side plate 14 according to the soft characteristics of the rubber, so as to facilitate the next time to knock the side plate 14.
[0025] Reference Figure 5 The bottom of the stirring rod 6 is fixedly connected with a bottom rod 16 , and the outer wall of the bottom rod 16 is fixedly connected with a spiral plate 17 , and the spiral plate 17 is tightly attached to the bottom of the inner wall of the stirring cylinder 4 .
[0026] By arranging the bottom rod 16 at the bottom of the stirring rod 6, the spiral plate 17 can be easily installed at the bottom of the mixing cylinder 4. When the concrete is poured out from the bottom of the mixing cylinder 4, the bottom rod 16 and the spiral plate 17 can rotate with the stirring rod 6, so that the concrete at the bottom of the inner wall of the mixing cylinder 4 can be evenly transferred downward.
[0027] Reference Figure 5 A scraping rod 18 is fixedly connected to the bottom of the stirring rod 6 , and one side of the scraping rod 18 is in contact with the inner wall of the stirring cylinder 4 .
[0028] By arranging a scraper rod 18 at the bottom of the stirring rod 6, the scraper rod 18 at the bottom can be driven to rotate when the stirring rod 6 rotates. The bottom of the inner wall of the mixing tank 4 can be cleaned by the rotation of the scraper plate to prevent concrete from accumulating on the slope at the bottom of the mixing tank 4.
[0029] Reference Figure 1 A cover plate 19 is fixedly connected to the top of the mixing cylinder 4 . The shape of the cover plate 19 is consistent with the shape of the transmission belt 8 . The cover plate 19 is sleeved on the outer wall of the transmission belt 8 .
[0030] By arranging a cover plate 19 at the top of the mixing cylinder 4, the cover plate 19 can be used to protect the outside of the transmission belt 8 when the transmission belt 8 rotates, preventing external force factors from affecting the transmission belt 8 and the second pulley 9.
[0031] Reference Figure 1 The outer wall of the pull rod 3 is fixedly connected with an anti-slip sleeve 20 , the anti-slip sleeve 20 is made of rubber, and an annular groove is opened on the outer wall of the anti-slip sleeve 20 . There are multiple groups of annular grooves, which are distributed in parallel on the outer wall of the anti-slip sleeve 20 .
[0032] By providing a rubber anti-skid sleeve 20 on the outer wall of the pull rod 3, when the base plate 1 needs to be pulled to one side, the friction of the outer wall of the anti-skid sleeve 20 can be increased through the multiple groups of annular grooves provided on the anti-skid sleeve 20, thereby being more conducive to pulling the pull rod 3.
[0033] Working principle: In order to solve the problem of easy blockage inside the mixer, when the road needs to be paved, the material can be put into the mixing cylinder 4 through the feed port 15, and the rotating motor 5 is started, and the stirring rod 6 is driven by the rotating motor 5 to rotate. When the stirring rod 6 rotates, the material will be stirred evenly. After the material is stirred evenly, the valve can be opened to allow the material to fall downward through the bottom of the mixing cylinder 4, so that the road can be paved. When the stirring rod 6 rotates, it will drive the first pulley 7 set on the outer wall to rotate, and when the first pulley 7 rotates, it will drive the transmission belt 8 to start The second pulley 9 can be driven to rotate by the rotation of the transmission belt 8. When the second pulley 9 rotates, the transmission rod 11 and the slapping plate 12 at the bottom can be driven to rotate together. When the slapping plate 12 rotates, it will hit the side plate 14 on one side, and make the side plate 14 and the annular plate 13 vibrate. Since the annular plate 13 is arranged at the bottom of the mixing cylinder 4, the vibration of the annular plate 13 can be transmitted to the mixing cylinder 4, and the concrete on the inner wall of the mixing cylinder 4 can be shaken off to prevent larger particles in the concrete from sticking to the mixing cylinder 4. Since the material of the slapping plate 12 is rubber, the slapping plate 12 will hit the mixing cylinder 4. After hitting the side plate 14, the slapping plate 12 will pass over the side plate 14 according to the soft characteristics of the rubber, so that it is convenient to hit the side plate 14 next time. By arranging the bottom rod 16 at the bottom of the stirring rod 6, it is convenient to install the spiral plate 17 at the bottom of the mixing cylinder 4. When the concrete is poured out from the bottom of the mixing cylinder 4, the bottom rod 16 and the spiral plate 17 can be rotated with the stirring rod 6, so that the concrete at the bottom of the inner wall of the mixing cylinder 4 can be evenly transmitted downward. By arranging the scraping rod 18 at the bottom of the stirring rod 6, the scraping rod 18 at the bottom can be driven to rotate when the stirring rod 6 rotates, so that the concrete at the bottom of the inner wall of the mixing cylinder 4 can be evenly transmitted downward. The bottom of the inner wall of the mixing cylinder 4 is cleaned by rotating the plate to prevent concrete from accumulating on the slope at the bottom of the mixing cylinder 4. By arranging a cover plate 19 at the top of the mixing cylinder 4, the cover plate 19 can be used to protect the outside of the transmission belt 8 when the transmission belt 8 rotates to prevent external force factors from affecting the transmission belt 8 and the second pulley 9. By arranging a rubber anti-skid sleeve 20 on the outer wall of the pull rod 3, when it is necessary to pull the bottom plate 1 to one side, the friction of the outer wall of the anti-skid sleeve 20 can be increased through the multiple sets of annular grooves arranged on the anti-skid sleeve 20, which is more conducive to pulling the pull rod 3.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
