[0004] Preferably: the quick-release mechanism includes: an inner cylinder, the inner cylinder is cylindrical, a bearing is installed on the inner side of the grinding roller, the inner cylinder is installed on the inner side of the bearing, the lower end of the inner cylinder is longer than the grinding roller, and a side groove is opened on one side of the lower end of the inner cylinder, a small ball is placed inside the side groove, the outer diameter of the side groove is smaller than the diameter of the small ball, the inner diameter of the side groove is consistent with the diameter of the small ball, and the side groove is inclined at 5° to the inside of the inner cylinder, the quick-release mechanism also includes: a placement groove, a placement groove is provided inside the roller shaft, and a limit groove is provided inside the placement groove.

[0005] Preferably: a stepped groove is provided inside the inner cylinder, a sliding protrusion is placed inside the stepped groove, the protrusion is integrally formed and fixedly connected to the middle part of the mounting column, the mounting column slides up and down in the inner cylinder, a spring is provided between the stepped groove and the protrusion, a groove is provided on the side wall of the lower end of the mounting column, the depth of the groove can accommodate a small ball, under normal conditions, the spring bounces the mounting column up, the groove of the mounting column is located above the small ball, the side wall of the mounting column abuts against the small ball, and one side of the small ball is clamped in the limit groove.

[0006] Beneficial effect: Press down the installation column, and the installation column moves downward, the spring is compressed, and the downward-moving installation column will drive the groove at the bottom of the installation column to contact the ball. Since the side groove has a certain slope, the ball in the side groove will slide into the groove. At this time, the ball originally stuck in the limit groove is released, and then the staff can directly pull out the grinding roller and the inner cylinder from the roller shaft to achieve disassembly. When installation is required, quick installation can be achieved in the same way. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Reference Figures 1 to 3 A concrete processing grinding machine includes a roller shaft 1 and a grinding roller 3, and a quick release mechanism is provided between the grinding roller 3 and the roller shaft 1.

[0013] Preferably: the quick release mechanism includes: an inner cylinder 302, the inner cylinder 302 is cylindrical, a bearing 301 is installed on the inner side of the grinding roller 3, the inner cylinder 302 is installed on the inner side of the bearing 301, the lower end of the inner cylinder 302 is longer than the grinding roller 3, and a side groove 305 is opened on one side of the lower end of the inner cylinder 302, a small ball 306 is placed inside the side groove 305, the outer diameter of the side groove 305 is smaller than the diameter of the small ball 306, the inner diameter of the side groove is at least the same as the diameter of the small ball 306, and the side groove 305 is inclined at 5° to the inside of the inner cylinder 302, the quick release mechanism also includes: a placement groove 101, a roller shaft 1 There is a placement groove 101 inside, and a limit groove 102 is provided inside the placement groove 101. Press down the installation column 4, and the installation column 4 moves downward. The spring 307 is compressed, and the downward-moving installation column 4 will drive the groove 402 at the lower part of the installation column 4 to contact with the ball 306. Since the side groove 305 has a certain slope, the ball 306 in the side groove 305 will slide into the groove 402. At this time, the ball 306 originally stuck in the limit groove 102 is released, and then the staff directly pulls out the grinding roller 3 and the inner cylinder 302 from the roller shaft 1 to achieve disassembly.

[0014] Preferably, a stepped groove 304 is provided inside the inner cylinder 302, a sliding protrusion 401 is placed inside the stepped groove 304, the protrusion 401 is integrally formed and fixedly connected to the middle of the mounting post 4, the mounting post 4 slides up and down in the inner cylinder 302, a spring 307 is provided between the stepped groove 304 and the protrusion 401, a groove 402 is provided on the side wall of the lower end of the mounting post 4, the depth of the groove 402 can accommodate a small ball, and under normal conditions, the spring 307 bounces the mounting post 4, and the groove 402 of the mounting post 4 is located above the small ball 306 The side wall of the mounting post 4 abuts against the ball 306, and one side of the ball 306 is engaged in the limiting groove 102. When installation is required, similarly, the mounting post 4 is first pressed down to allow the ball 306 to have space to move in the groove 402, and then the inner cylinder 302 is placed in the placement groove 101 of the roller shaft 1, and then the mounting post 4 is released. The spring 307 resets and drives the mounting post 4 to move upward.
