An anchoring agent abrasive mixing device, comprising a mixing barrel, a stirring mechanism is arranged in the mixing barrel, a screw rod is installed in the mixing barrel against the wall, and a driving motor for driving the rotation of the screw rod is arranged on the mixing barrel, so that the The screw comprises a first threaded part on the upper part and a second threaded part on the lower part, the thread directions of the first threaded part and the second threaded part are opposite, and the first threaded part and the second threaded part are symmetrically sleeved with The nut sleeve is provided with an annular scraper adapted to the inner wall of the mixing barrel, and the rotation of the screw makes the nut sleeves located on the first threaded part and the second threaded part move toward each other or relatively deviate from each other. The movement will drive the annular scraper to scrape off the material on the inner wall of the mixing barrel, so as to prevent the material from accumulating on the inner wall of the mixing barrel for a long time, and ensure the cleaning of the mixing barrel.
