Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically a concrete mixer. Background Technology

[0002] Concrete, or simply concrete, is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] Existing concrete mixers typically use a single mixing device to mix concrete raw materials, resulting in low mixing efficiency. Furthermore, a large amount of raw materials remain on the inner wall during the mixing process, reducing the utilization rate of the raw materials and making subsequent cleaning inconvenient.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0022] Please see Figure 1-3This utility model provides a technical solution: a concrete mixer, including a base plate 1, a support frame 2 fixedly connected to the upper end of the base plate 1, a mixing tank 3 arranged below the support frame 2, an mounting frame 4 fixedly connected to the middle of the top of the support frame 2, a drive device 5 fixedly connected to one end of the mounting frame 4, a main bevel gear 6 fixedly connected to the output end of the drive device 5 extending into the interior of the mounting frame 4, a secondary bevel gear 7 meshing with the upper end of the main bevel gear 6, a rotating rod 8 fixedly connected inside the secondary bevel gear 7, the other end of the rotating rod 8 extending into the interior of the mixing tank 3, a plurality of evenly distributed mixing rods 9 fixedly connected to the outer side of the rotating rod 8, a secondary bevel gear 10 meshing with the lower end of the main bevel gear 6, a rotating rod 11 fixedly connected inside the secondary bevel gear 10, the other end of the rotating rod 11 extending into the interior of the mixing tank 3, a connecting rod 12 fixedly connected to the outer side of the rotating rod 11, and a mixing frame 13 cooperating with the mixing rods 9 fixedly connected to the bottom end of the connecting rod 12.

[0023] Specifically, concrete raw materials are added into the mixing drum 3. The output of the drive device 5 drives the main bevel gear 6 to rotate, which in turn drives the secondary bevel gear 7 to rotate. The secondary bevel gear 7 drives the rotating rod 8 to rotate, which in turn drives the mixing rod 9 to rotate, thus mixing the concrete raw materials. At the same time, the main bevel gear 6 drives the secondary bevel gear 10 to rotate in the opposite direction to the secondary bevel gear 7. The secondary bevel gear 10 drives the rotating rod 11 to rotate, which in turn drives the connecting rod 12 to rotate, thus driving the mixing frame 13 to rotate, further mixing the concrete raw materials. The opposite rotation of the mixing rod 9 and the mixing frame 13 improves the mixing effect of the concrete raw materials and increases the production rate.

[0024] Understandably, the combined use of the mixing rod 9 and the mixing frame 13 further enhances the mixing effect. The mixing rod 9 is evenly distributed on the outside of the rotating rod 8, while the mixing frame 13 is connected to the rotating rod 11 via the connecting rod 12. The two form a complex mixing path inside the mixing drum 3, which allows the concrete raw materials to be mixed more thoroughly and evenly, improving the production rate and mixing quality.

[0025] In some embodiments, such as Figure 3 As shown, the inner wall of rotating rod 2 11 is rotatably connected to the outer wall of rotating rod 1 8. Specifically, rotating rod 2 11 serves to limit the movement of rotating rod 1 8.

[0026] The rotating connection design between rotating rod 11 and rotating rod 8 not only allows them to rotate relative to each other, but also ensures that their relative positions remain stable during the mixing process. This helps prevent structural deformation or damage caused by uneven force during mixing, thereby improving the overall stability and service life of the mixer.

[0027] In some embodiments, such as Figure 3As shown, a brush plate 14 is fixedly connected to one end of the connecting rod 12 near the mixing tank 3, and the brush plate 14 is fitted against the inner wall of the mixing tank 3.

[0028] Specifically, the connecting rod 12 drives the brush plate 14 to rotate, scraping off the concrete raw materials adhering to the inner wall of the mixing tank 3, and mixing them to improve the utilization rate of the raw materials.

[0029] In some embodiments, such as Figure 1 As shown, a water tank 15 is fixedly connected to one end of the support frame 2, a water pump 16 is fixedly connected to the outlet of the water tank 15, a water outlet pipe 17 is fixedly connected to the outlet end of the water pump 16, and the other end of the water outlet pipe 17 extends through the inner wall of the left end of the support frame 2 to the top of the mixing tank 3.

[0030] Specifically, the water in the water tank 15 can be added to the mixing tank 3 through the outlet pipe 17 via the output of the water pump 16, thereby controlling the water ratio in the mixing tank 3 and facilitating subsequent cleaning of the inside of the mixing tank 3 in conjunction with the brush plate 14.

[0031] In some embodiments, a fixing rod 18 is fixedly connected to both the left and right ends of the mixing tank 3, and the other end of the fixing rod 18 is fixedly connected to the inner wall of one side of the support frame 2. A fixing buckle 19 is fixedly connected to one side of the inner wall of the top of the support frame 2, and the fixing buckle 19 is fixedly connected to the outer wall of the water outlet pipe 17.

[0032] Specifically, the fixing rod 18 serves to fix and support the mixing tank 3, and the fixing buckle 19 serves to fix and support the water outlet pipe 17.

[0033] In some embodiments, such as Figure 1 As shown, the bottom of the mixing tank 3 is provided with a discharge port 20, a sealing cover 21 is provided on the outside of the discharge port 20, and a receiving box 22 is provided below the sealing cover 21.

[0034] Specifically, the concrete after mixing is discharged through the discharge port 20, the discharge port 20 is sealed through the sealing cover 21 during the mixing process, and the concrete is collected through the collection box 22.

[0035] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
