[0032] The drive unit includes a U-shaped frame, which includes a horizontal plate and vertical plates fixed at both ends of the horizontal plate. A rotating column 3 is rotatably connected between the two vertical plates. A first pulley 31 is rotatably connected to the side wall of one of the vertical plates. The first pulley 31 is coaxially fixed to the rotating column 3. A first stirring rod 11 is coaxially fixed to a first bevel gear 12. A second bevel gear 13 meshes with one side of the first bevel gear 12. A second pulley 32 is coaxially fixed to the second bevel gear 13. The first pulley 31 and the second pulley 32 are rotatably connected by a belt. The drive unit is used to drive the reciprocating mechanism to perform lateral reciprocating motion.

[0033] The rotating column 3 has a guide rail 4 that is connected end to end on its circumferential side wall, and the guide rail 4 is slidably connected to the connecting column 41.

[0034] The reciprocating mechanism includes a first slide rail 5, a first rack 51 slidably connected to one side of the first slide rail 5, a fourth gear 52 meshing with one side of the first rack 51, the fourth gear 52 being coaxially and fixedly connected to the first connecting rod 24, a rectangular opening being provided on the upper surface of the first slide rail 5, a movable seat 53 being slidably connected inside the rectangular opening, the movable seat 53 being fixedly connected to the upper surface of the first rack 51, and the movable seat 53 being hinged to the connecting column 41.

[0035] The outer wall of the first stirring rod 11 is provided with a plurality of linearly arranged first stirring blades 110, and the outer wall of the second stirring rod 27 is provided with a plurality of linearly arranged second stirring blades 270.

[0036] The first stirring blade 110 and the second stirring blade 270 are arranged in an alternating pattern.

[0037] Three circular array of support columns are fixedly connected to the upper surface of the support circular plate 10. An L-shaped plate is fixedly connected to the support columns. The L-shaped plate includes a vertical plate and a horizontal plate 6. The horizontal plate and the first slide rail 5 are fixedly connected to one of the horizontal plates 6.

[0038] In use, the first motor 30 is started, which drives the second bevel gear 13 to rotate, which in turn drives the first bevel gear 12 to rotate. The rotation of the first bevel gear 12 drives the first stirring rod 11 to rotate, thereby stirring the cement mortar inside the cylinder 1. Simultaneously, when the first bevel gear 12 rotates, it drives the first gear 21 to rotate. When the first gear 21 rotates, it drives the second gear 22 to rotate. When the second gear 22 rotates, it drives the third gear 23 to rotate, thereby driving the second stirring rod 27 to rotate. The rotation of the second stirring rod 27 improves the stirring effect of the cement mortar inside the cylinder 1. When the first bevel gear 12 rotates, it drives the second pulley 32 to rotate. When the second pulley 32 rotates, it drives the first pulley 31 to rotate. When the first pulley 31 rotates, it drives the rotating column 3 to rotate. When the rotating column 3 rotates, it drives the moving seat 53 to reciprocate. The sliding motion causes the first rack 51 to slide back and forth on the first slide rail 5. The first rack 51 drives the fourth gear 52 to rotate forward and backward. The forward and reverse rotation of the fourth gear 52 drives the first connecting rod 24 to move, thereby adjusting the angle between the first connecting rod 24 and the third connecting rod 26, which in turn adjusts the position of the third gear 23. When the second stirring rod 27 rotates, it can move closer to or further away from the first stirring rod 11, further improving the mixing effect of the cement mortar in the cylinder 1. This device is ingeniously designed and easy to operate. Through the rotation of the first stirring rod 11 and the second stirring rod 27, the mixing effect of the cement mortar in the cylinder 1 is improved. At the same time, the second stirring rod 27 can move away from or closer to the first stirring rod 11, and the first stirring blade 110 and the second stirring blade 270 are arranged in an alternating manner, further improving the mixing effect of the cement mortar in the cylinder 1.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
