[0034] In this embodiment, the rotating shaft 300 and the second pulley 112 are connected via a connecting key.

[0035] In this embodiment, the rotating motor is not limited to driving the rotating shaft 300 to rotate by belt transmission.

[0037] When this embodiment is used, the stirring paddle 600 is detachably connected to the rotating shaft 300 through the installation tube 400, which can facilitate the installation and removal of the stirring paddle 600, thereby facilitating the maintenance and replacement of the stirring paddle 600, reducing the difficulty of maintaining and replacing the stirring paddle 600 and saving labor.

[0038] In this embodiment, the connection rod 500 can be arranged to facilitate adjustment of the distance between the stirring paddle 600 and the rotating shaft 300 , thereby meeting different usage requirements.

[0039] In this embodiment, the number of connecting rods 500 arranged on the side wall of the mounting tube 400 is not limited to four, and can be selected accordingly according to actual conditions, such as the number of connecting rods 500 fixedly connected to the side wall of the mounting tube 400 along its circumference is two, three, etc.

[0040] As a further description of the above embodiment, the middle of the lower surface of the mounting tube 400 is recessed inward to form a mounting groove 113, and the rotating shaft 300 is connected to the mounting groove 113 by bolts.

[0042] In this embodiment, the inner diameter of the mounting groove 113 is equal to the outer diameter of the rotating shaft 300, which ensures that the rotating shaft 300 can be installed in the mounting groove 113 and at the same time plays a positioning role for the rotating shaft 300, preventing the rotating shaft 300 from shaking in the mounting groove 113, further improving the stability of the connection between the stirring element and the rotating shaft 300, thereby improving the stability of the stirring equipment during operation.

[0043] As a further description of the above embodiment, the stirring paddle 600 is in the shape of a triangular prism, one side of the triangular prism is a mounting surface 700 , two sets of parallel stirring members are provided on the mounting surface 700 , and the other two sides of the triangular prism are guide ends 800 .

[0044] When this embodiment is used, two sets of stirring pieces are arranged on the mounting surface 700 to increase the contact area between the stirring pieces and the concrete, and expand the contact range between the stirring pieces and the concrete, so as to better drive the concrete to rotate and improve the stirring effect of the concrete. At the same time, the guide ends 800 formed on the other two sides of the triangular prism can guide the concrete during the stirring process, reduce the resistance of the concrete to the stirring paddle 600 during the stirring process, and guide the concrete to the left and right sides through the two guide ends 800 of the triangular prism, so that the stirring piece can better stir the concrete and further improve the stirring effect.

[0045] In this embodiment, the number of stirring members on each mounting surface 700 is not limited to two groups, and can be set accordingly according to actual conditions, such as setting one group or three groups of stirring members on each mounting surface 700.

[0046] As a further description of the above embodiment, the stirring member includes a first stirring shaft 115 and a plurality of second stirring shafts 116. The first stirring shaft 115 is fixedly connected to the mounting surface 700. Both ends of the first stirring shaft 115 extend out of the mounting surface 700 and are respectively connected to a plurality of second stirring shafts 116.

[0047] When this embodiment is used, the two ends of the first stirring shaft 115 extend out of the mounting surface 700 to stir the concrete in a horizontal direction on both sides of the stirring paddle 600, thereby improving the stirring effect of the concrete.

[0048] Both ends of the first stirring shaft 115 extend out of the mounting surface 700 and are respectively connected to a plurality of second stirring shafts 116 . The second stirring shafts 116 can scoop up concrete, so that the concrete is mixed up and down, further improving the mixing effect of the concrete.

[0049] As a further description of the above embodiment, a plurality of the second stirring shafts 116 are obliquely disposed on the first stirring shaft 115 .

[0051] In this embodiment, the second stirring shaft 116 and the stirring paddle 600 are fixedly connected via the connecting rod 117 to ensure the stability of the connection between the second stirring shaft 116 and the stirring paddle 600, thereby improving the stability of the stirring device and ensuring safety during operation.

[0052] Example 2

[0053] like Figure 4 As shown, among the four sets of connecting rods 500 and stirring paddles 600, the length of one set of connecting rods 500 is shortened (for example, shortened by 50 cm), so that the set connecting rods 500 and stirring paddles 600 can stir concrete in different areas, thereby improving the mixing effect of concrete.

[0054] Of course, the four connecting rods 500 can be set to different lengths according to needs. For example, the distances between the four connecting rods 500 and the vertical center line of the rotating shaft 300 are 30 cm, 50 cm, 70 cm, and 90 cm respectively.

[0055] In summary, the working principle of the concrete mixing equipment is:

[0056] When in use, firstly, concrete raw materials are fed into the interior of the mixing drum 200 through the feeding pipe 118, and then the rotating shaft 300 is driven to rotate by the driving component, and the mixing component is driven to rotate by the rotating shaft 300.

[0057] When the stirring assembly rotates, the concrete is guided by the guide end 800 provided on the stirring paddle 600, so as to reduce the resistance of the stirring paddle 600 when stirring the concrete, and the concrete is guided to both sides of the stirring paddle 600 by the guide end 800, and the concrete is stirred by the stirring members provided on both sides of the stirring paddle 600. Since the second stirring shaft 116 is arranged at an angle, the concrete below can be scooped up, so that the upper and lower layers of concrete can be mixed more evenly, further improving the mixing effect.

[0058] In summary, the utility model guides the concrete through the guide end, reduces the resistance of the concrete to the stirring paddle during the mixing process, and guides the concrete to the left and right sides through the guide end, so that the stirring shafts arranged on both sides of the stirring paddle can better stir the concrete, thereby improving the mixing effect. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
