The outer wall of the front surface of the round rod 9 is fixedly connected with A support rod 11 supports a scraper 12. The middle part of the support rod 11 passes through and is slidably connected with the scraper 12. The scraper 12 can rotate to scrape off the concrete adhered to the inner wall of the mixer 1. The outer wall of the round rod 9 is slidably connected with a disc 8 near the top of the support rod 11. The disc 8 supports a guide rod 10. The outer wall of the front surface of the disc 8 is fixedly connected with the guide rod 10. The guide rod 10 can drive the scraper 12 to move toward the middle. The top of the disc 8 is rotatably connected with a pull rod 3. The pull rod 3 can drive the disc 8 to move and drive the guide rod 10 to move at the same time. The left side of the pull rod 3 passes through and is slidably connected with a limit rod 5. The limit rod 5 cooperates with the circular groove 2 to limit the pull rod 3.

[0026] Furthermore, the limiting rod 5 and the pulling rod 3 are elastically connected by a spring 14. The limiting rod 3 is released by sliding the limiting rod 5 out of the circular groove 2 and squeezing the spring 14. At the same time, the reverse force of the squeezing of the spring 14 drives the limiting rod 5 to return to the circular groove 2 to limit the pulling rod 3. A shifting block is fixedly connected to the front surface of the limiting rod 5. The limiting rod 5 is moved by shifting the shifting block. A feed box 7 is fixedly connected to the right side of the mixer 1, and concrete material can be added into the feed box 7 from the top. A screen 6 is fixedly connected to the inner wall of the left side of the feed box 7, and the screen 6 can screen out larger gravel. , preventing larger gravel from entering the mixer 1 and increasing the load of the mixer 1, thereby increasing the service life of the mixer 1. A guide block 13 is fixedly connected to the inner wall of the bottom end of the feed box 7 near the bottom of the screen 6. The guide block 13 can make the concrete material falling from the screen 6 slide into the mixer 1. The limit rod 5 slides on the inner wall of the circular groove 2, which can limit the pull rod 3.

After the smaller crushed stones fall into the top of the guide block 13 through the screen 6, they slide to the left through the inclined surface of the guide block 13 to the mixer 1 for mixing. The larger crushed stones are screened out by the screen 6 to prevent the larger crushed stones from entering the mixer 1 for mixing, thereby reducing the load of the mixer 1, increasing the service life of the mixer 1, and improving the applicability.

[0029] After the limit rod 5 is moved to the right and the spring 14 is squeezed out of the circular groove 2, the limit of the pull rod 3 is released. At this time, the pull rod 3 is moved downward to drive the disc 8 to move downward and the guide rod 10 to move downward. The scraper 12 is squeezed by the inclined guide rod 10 and the support rod 11 is cooperated to make the scraper 12 move in the direction close to the circular rod 9, so that the scraper 12 moves to the middle of the support rod 11. The reverse force of the spring 14 is squeezed to drive the limit rod 5 to reset and slide into the circular groove 2 to limit the pull rod 3 and the circular disc 8. At this time, starting the motor can drive the circular rod 9 to rotate and drive the scraper 12 to rotate through the support rod 11. The rotation of the scraper 12 increases the stirring effect, and the stirring After the mixer 1 is stirred and mixed, less material will adhere to the inner wall of the mixer 1 after the concrete material is mixed. At this time, after turning off the motor, by sliding the limit rod 5 out of the circular groove 2, the pull rod 3 is moved upward to drive the disc 8 and the inclined guide rod 10 to move upward to cooperate with the support rod 11 to move the scraper 12 toward the inner wall of the mixer 1. After the scraper 12 is released from the inner wall of the mixer 1, the limit rod 5 slides into the circular groove 2 to limit the scraper 12. At this time, the motor can be started to drive the scraper 12 to rotate and the concrete material adhered to the inner wall of the mixer 1 can be scraped off to prevent the concrete from adhering to the inner wall and causing different batches of concrete to be mixed together, thereby improving the quality of concrete.
