[0002] Concrete is highly used and widely applied in the construction industry. In buildings, concrete mainly plays the roles of framework and lubrication, making construction more convenient. Concrete materials usually mainly consist of cementitious materials, combined with water, sand, fine stone particles, etc., adding some other chemical elements and minerals, and are mixed in a mixing device according to a certain proportion, and finally formed after stirring.

[0003] The patent publication number CN202221236948.3 discloses a high-efficiency sand and stone mixing device for concrete production. This solution realizes the stirring and mixing of sand and stone materials through the mixing paddles arranged inside. However, the mixing paddles in this solution can only rotate self - rotatably during operation and cannot rotate around a fixed point (revolve). As a result, the stirring area of the mixing paddles is limited, and it is impossible to efficiently mix the sand and stone materials over a large range, having certain defects and deficiencies, so improvement is needed.

Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of this utility model.

[0023] Embodiment

[0024] As Figure 1 , Figure 2 and Figure 3As shown in the figure, an efficient sand and gravel mixing device for concrete production proposed in an embodiment of the present utility model includes a mixing tank 1 and a cover plate 5 fixedly connected to the top of the mixing tank 1. A circular cavity 14 is provided on one side of the mixing tank 1, and a circular plate 2 is rotatably connected at the circular cavity 14 of the mixing tank 1. A turntable 7 is rotatably connected to the inner wall of the mixing tank 1 corresponding to the circular plate 2. An array of stirring components 8 is arranged between the turntable 7 and the circular plate 2. The stirring component 8 includes a stirring shaft 801 rotatably connected between the circular plate 2 and the turntable 7, and a plurality of special-shaped stirring blades 802 fixedly arranged on the stirring shaft 801 at equal intervals. One end of the stirring shaft 801 extends to the outside of the circular plate 2 and is fixedly connected with a movable gear 9. A fixed frame 3 is fixedly connected to the mixing tank 1 on one side of the circular plate 2, and a static gear 10 is fixedly connected to the fixed frame 3 by bolts. The movable gear 9 is meshed with the static gear 10.

[0025] It should be noted that the cover plate 5 is used for the protection and sealing of the top of the mixing tank 1. By providing a circular cavity 14 on one side of the mixing tank 1 for the installation of the circular plate 2, both the circular plate 2 and the turntable 7 are rotatably connected to the mixing tank 1 and can rotate in the same direction. By arranging the stirring component 8 between the circular plate 2 and the turntable 7, the stirring component 8 is composed of a stirring shaft 801 rotatably connected between the circular plate 2 and the turntable 7 and special-shaped stirring blades 802 fixed on the stirring shaft 801. When the circular plate 2 and the turntable 7 rotate, it can make the stirring shaft 801 revolve. By fixing a movable gear 9 at one end of the stirring shaft 801 and meshing the movable gear 9 with the static gear 10, the automatic rotation of the stirring shaft 801 is realized. Therefore, when the circular plate 2 rotates, the revolution and rotation of the stirring shaft 801 and the special-shaped stirring blades 802 can be realized, effectively expanding the stirring area and improving the stirring effect of the sand and gravel materials.

[0026] As Figure 1 , Figure 2 and Figure 3 shown, in some embodiments, waterproof bearings are provided at the connection between the circular plate 2 and the mixing tank 1 and at the connection between the stirring shaft 801 and the circular plate 2.

[0027] It should be noted that the setting of the waterproof bearing can play a protective role and prevent liquid from leaking out.

[0028] As Figure 1 shown, in some embodiments, a toothed ring 4 is fixedly connected to the outer wall of the circular plate 2, and a motor 13 is installed on one side of the mixing tank 1. A driving gear 12 is fixedly connected to one side of the motor 13, and the driving gear 12 is meshed with the toothed ring 4.

[0029] It should be noted that when it is necessary to stir and mix sand and gravel materials, the driving motor 13 operates, the motor 13 drives the driving gear 12 to rotate, the driving gear 12 is meshed and connected with the toothed ring 4, so that the circular plate 2 can rotate on the mixing tank 1. The stirring shaft 801 is rotatably connected between the circular plate 2 and the turntable 7. When the circular plate 2 rotates, the stirring shaft 801 can revolve. Since a movable gear 9 is fixed to the end of the stirring shaft 801 and the movable gear 9 is meshed and connected with the static gear 10, the rotation and revolution of the stirring shaft 801 are realized. The movable gear 9 and the static gear 10 are both located outside the mixing tank 1, which can avoid the influence of sand and gravel and save internal space.

[0030] As Figure 1 and Figure 2 shown, in some embodiments, support legs 11 are fixedly connected to the four corners of the lower surface of the mixing tank 1, and a discharge pipe is connected to the discharge hole 15 opened at the bottom of the mixing tank 1.

[0031] It should be noted that the support legs 11 are used for supporting the device, and the discharge pipe is used for discharging the mixed materials.

[0032] As Figure 1 shown, in some embodiments, a feed hopper 6 is fixedly connected to the feed inlet of the cover plate 5 to realize the feeding of sand and gravel materials.

[0033] As Figure 3 shown, in some embodiments, a support plate 803 is integrally formed on one side of the special-shaped stirring blade 802.

[0034] It should be noted that the arc angle of the support plate 803 is set along the rotation direction of the stirring shaft 801, which can play a role in crushing sand and gravel materials, effectively removing and crushing large pieces of sand and gravel materials, and then realizing the effective mixing of sand and gravel materials.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
