[0032] In order to solve the problem of the spiral conveyor rod 13 being able to rotate, a third bevel gear 11 is fixedly installed on the outside of the crossbar 9, and a conveyor box 12 is fixedly installed on one side of the mixing cylinder 1.

[0033] In order to solve the problem of the spiral conveyor rod 13 being able to rotate, a vertical rod 14 is fixedly provided at the bottom of the spiral conveyor rod 13, and a fourth bevel gear 15 is fixedly provided at the bottom of the vertical rod 14. The fourth bevel gear 15 is located at the top of the third bevel gear 11 and meshes with the third bevel gear 11.

[0034] In order to solve the problem of further crushing of larger aggregates, a baffle 16 is fixedly installed inside the conveyor box 12. The baffle 16 is movably connected to the vertical rod 14 through a bearing. A feed inlet 17 is opened on the mixing cylinder 1, and a discharge outlet 18 is opened on the mixing cylinder 1.

[0038] In order to solve the problem of supporting the mixing cylinder 1, multiple support columns 25 are fixedly provided at the bottom of the mixing cylinder 1.

[0039] Working Principle: In use, this invention is first connected to an external power source. The materials to be mixed are then fed into the mixing drum 1 through the two feed hoppers 23. Simultaneously, the motor 2 is started, driving the rotating rod 3 to rotate. The rotation of the rotating rod 3 causes multiple crushing blades 5 and the mixing plate 6 outside the rotating rod 3 to rotate. The crushing blades 5 crush the materials inside the mixing drum 1. Due to the design of the mesh plate 4, only materials of the appropriate size can pass through the mesh plate 4 and enter the bottom of the mesh plate 4. While the rotating rod 3 is rotating, it also drives the mixing plate 6 to rotate, thus mixing the materials. The rotation of plate 6 mixes the material passing through screen 4. The rotation of rod 3 also drives the first bevel gear 7, which in turn drives the second bevel gear 8, which in turn drives the crossbar 9. The crossbar 9 then drives multiple striking plates 10 on its exterior, causing them to strike the screen 4. This, combined with the interaction of multiple springs 22, causes the screen 4 to vibrate continuously. This vibration causes the material on top of the screen 4 to vibrate, facilitating the passage of larger, non-compliant materials through the screen 4. Larger materials cannot pass through the mesh plate 4, while larger materials enter the conveyor box 12 through the feed inlet 17 on the mixing drum 1. When the crossbar 9 rotates, it also drives the third bevel gear 11 to rotate, which in turn drives the fourth bevel gear 15 to rotate. The fourth bevel gear 15 then drives the vertical rod 14 to rotate, which in turn drives the spiral conveyor rod 13 at the top of the vertical rod 14 to rotate. The spiral conveyor rod 13 can convey some larger materials inside the conveyor box 12 to the top of the conveyor box and then discharge them through the discharge port 18. After passing through the discharge port 18, the material can be further processed by the crusher 5. The aggregate is crushed using an auxiliary mechanism with multiple crushing blades. The mesh plate 4, the striking plate 10, and the spring 22 work together to strike the mesh plate 4, facilitating aggregate screening. Aggregates that are not up to size can be conveyed to the top of the conveyor box 12 via the screw conveyor 13, where they can be crushed again by the crushing blades 5. This ensures that the aggregates reach the required size and pass through the mesh plate 4, preventing larger aggregates from being easily mixed with the sand and gravel. This guarantees the quality of the mixed concrete and makes it easier for operators to use.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
