6. The production stirring and mixing device for freeze-thaw resistant facing plain concrete according to claim 2, characterized in that: The top and bottom of one side of the connecting plate (25) are fixedly connected to a baffle (26), the front end and the rear end of the top of the groove (27) are fixedly connected to a guide rod (28), and the lower ends of the two guide rods (28) pass through the outside of the connecting plate (25) and are fixedly connected to the inner bottom of the groove (27).

7. The production stirring and mixing device for freeze-thaw resistant facing plain concrete according to claim 2, characterized in that: Both ends of the second transmission rod (31) are movably connected to bearings fixedly installed at the top positions on both sides of the transmission box (5).

8. The production stirring and mixing device for freeze-thaw resistant facing plain concrete according to claim 2, characterized in that: A bearing is arranged at a top position on the surface of the first transmission rod (17), the surface of the first transmission rod (17) is movably connected to the inner ring of the bearing, a fixing frame is fixedly installed on the outer wall of the bearing, and the outer wall of the fixing frame is fixedly connected to the inner wall of the transmission box (5).

9. A mixing method for a production stirring and mixing device for freeze-thaw resistant facing plain concrete, comprising the production stirring and mixing device for freeze-thaw resistant facing plain concrete according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: Start the conveying motor (7), the crushing motor (12) and the driving motor (16) to operate. The conveying motor (7) drives the conveying rod (8) to rotate the spiral blade (9). The two crushing motors (12) drive the two crushing rollers (14) to rotate relative to each other. The driving motor (16) drives the rotating rod (20) to rotate the stirring rod (21) inside the stirring box (2). At the same time, the rotating rod (20) drives the transmission wheel (18) on its surface to rotate. Through the connection with the belt (19), the first transmission rod (17) and the transmission wheel (18) on its surface rotate synchronously. At this time, the first transmission rod (17) and the transmission wheel (18) on its surface rotate synchronously. The moving rod (17) drives the driving gear (32) to mesh with the driven gear (33) to rotate, thereby driving the second transmission rod (31) and the cam (35) to rotate. During the rotation of the cam (35), the spring (30) pushes the connecting plate (25) so that the contact wheel (34) at the bottom always keeps in contact with the cam (35), so that the connecting plate (25) drives the filter inclined plate (23) to move up and down as the cam (35) rotates. The connecting plate (25) slides on the two guide rods (28) in the groove (27), thereby ensuring the stability of the up and down shaking of the filter inclined plate (23). Step 2: The raw materials required for the anti-freeze-thaw facing plain concrete are fed in through the feed pipe (10), the raw materials enter the filter box (6) and fall on the filter inclined plate (23), the sand and gravel passing through the filter inclined plate (23) enter the mixing box (2) from the feed pipe (22), and the rotating stirring rod (21) stirs and mixes the raw materials. The larger sand and gravel will roll down along the inclination and shaking of the filter inclined plate (23) and enter the crushing box (3) through the feed pipe (24). The larger sand and gravel are crushed by the two rotating crushing rollers (14) during the falling process, and the crushed sand and gravel enter the conveying box (4) through the short inclined pipe (15); In step three, the crushed sand and gravel are transported upward by the spiral blades (9) until the sand and gravel enter the discharge pipe (10) through the long inclined pipe (11) and fall into the filter box (6) for filtration again. The sand and gravel after the second filtration enter the mixing box (2) for stirring and mixing. After stirring and mixing, the concrete is discharged by opening the valve on the discharge pipe on the front surface of the mixing box (2).
