Description

Technical Field

[0001] This utility model belongs to the field of concrete mixing technology, specifically a mixing device for concrete proportioning. Background Technology

[0002] Existing concrete mixers are devices that mix cement, sand, gravel, and water in a certain proportion to make concrete. They are commonly used in construction. The emergence of mixers has replaced manual mixing, greatly reducing labor costs.

[0003] Chinese patent application CN202320120659.5 discloses a concrete mixing device, including a housing with an inlet pipe fixed on the housing and an outlet pipe fixed at the lower end of the housing. A mixing mechanism is installed inside the housing, and an anti-clogging mechanism is installed in the outlet pipe. A water inlet pipe is fixed at the right end of the housing. The mixing mechanism includes a fixed box, a first motor, a first gear, a second gear, a rotating pipe, a connecting plate, a slider, a fixed rod, a first mixing rod, a rotating rod, and a second mixing rod. The fixed box is fixedly installed on the housing. This concrete mixing device has a mixing mechanism that is operated by the first motor, causing the first gear to drive the second gear to rotate. The rotation of the second gear drives the rotating pipe and the rotating rod to rotate, which in turn drives the connecting plate to rotate. This allows the first and second mixing rods to mix the contents of the housing, resulting in more uniform mixing and better blending compared to traditional dye mixers.

[0004] In existing and above-mentioned technologies, when using a mixer, raw materials such as sand, gravel, and cement are first poured into the mixer through the feed inlet. As the sand and gravel in the raw materials come into contact with water, their physical properties change, resulting in clumping and agglomeration. This clumping not only forms clumps of varying sizes but also prevents the raw materials from fully contacting and mixing, leading to uneven mixing and a decrease in the overall quality of the concrete raw materials. Therefore, a mixing device for concrete proportioning is proposed to address the above problems. Utility Model Content

[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] Example 1 Please see Figure 1-5 As shown, a concrete mixing device includes a base 10, a support rod 9 fixedly connected to the surface of the base 10, a roller 1 fixedly connected to the surface of the support rod 9, a mixing shaft 3 rotatably connected to the surface of the roller 1, and a motor 2 connected to the mixing shaft 3 through the inner wall of the roller 1 via a coupling. Its features include: a cavity is provided inside the stirring shaft 3, and multiple stirring rods 5 are fixedly connected to its surface at equal intervals; It also includes a central rod 11, which is rotatably connected in the cavity of the stirring shaft 3. A connecting rod 19 is connected to the surface of the central rod 11 through a rotating device. The connecting rod 19 passes through the side wall surface of the stirring shaft 3, and the passing position is rotatably connected through a bearing 18. Multiple equally spaced stirring blades 6 are fixedly connected to the surface of the connecting rod 19. During operation, the motor 2, which is fixed to the surface of the drum 1, is started. The motor 2 serves as the power output component of the entire device. When the motor 2 is running, it drives the stirring shaft 3, which is fixedly connected to its surface, to rotate. At this time, the power of the motor is transmitted through the stirring shaft. As the stirring shaft 3 rotates, it drives the connecting rod 19 to rotate as well. Since multiple stirring blades 6 are fixedly connected to the surface of the connecting rod 19, these stirring blades will rotate together with the connecting rod 19, thereby performing a stirring operation on the material. Setting multiple stirring blades 6 can increase the contact area with the material, allowing the material to be more thoroughly turned over and mixed during the stirring process, effectively reducing the situation where the material is not stirred properly in some areas, thus avoiding the problem of uneven stirring and improving the stirring quality and efficiency.

[0020] The rotating device includes a first bevel gear 12, a second bevel gear 20, and a bearing 18. The first gear 12 is fixedly connected to the surface of the central rod 11, and the second gear 20 is fixedly connected to the surface of the connecting rod 19. The first gear 12 and the second gear 20 are meshed together. During operation, as the connecting rod 19 rotates around the mixing shaft 3, a second gear 20 is located at the top of the connecting rod. This gear 12, which is connected to the surface of the central rod 11, is perpendicular to and meshes with the first gear 12. Since the central rod 11 is fixed on the drum 1, the drum 1 does not rotate when the mixing shaft 3 rotates. This causes the second gear 20 to make a circular motion around the first gear 12. The connecting rod 19 is rotatably connected to the mixing shaft 3 through a bearing 18. This allows the connecting rod 19 to rotate axially while rotating around the mixing shaft 3, ensuring full contact and mixing of the raw materials. This results in uniform overall mixing, improving the overall quality of the concrete raw materials and thus increasing work efficiency.

[0021] A groove is provided on the surface of the stirring rod 5 away from the stirring shaft 3. A fixing block 14 is slidably connected in the groove by a spring 15. An arc plate 4 is fixedly connected to the top of the fixing block 14. During operation, the mixing rod 5 drives the arc plate 4 to move. The surface of the arc plate 4 is in close contact with the inner wall of the drum 1, so that the arc plate 4 can scrape off the concrete stuck to the inner wall of the drum 1 when it moves, thereby improving the mixing effect. It can also scrape off the concrete stuck to the inner wall surface of the drum 1 during the cleaning process, preventing the problem of the concrete stuck to the inner wall of the drum 1 being difficult to clean after it dries.

[0022] A convex surface 16 is fixedly connected to the inner surface of the roller 1. The convex surface 16 is located on the upper part of the roller 1 and is strip-shaped to reduce the contact area between the arc plate 4 and the convex surface 16. During operation, because the concrete is located inside the lower part of the drum 1 during mixing, and the convex surface is located inside the upper part of the drum 1, the arc plate 4 can play its maximum role when rotating from the lower part. When it rotates to the upper part and contacts the convex surface, because the convex surface is strip-shaped, the springs fixed to the surface of the arc plate 4 vibrate when they contact, which can cause the concrete adhering to the arc plate to be shaken off. It can also reduce the friction between the arc plate 4 and the inner wall of the drum, thus protecting the arc plate 4 from wear.

[0023] The surface of the roller 1 is provided with an inspection port 13, and an iron plate is rotatably connected to the surface of the inspection port 13 via a hinge. During operation, staff can enter the interior of the drum 1 through the inspection port 13 on the surface of the drum 1 to easily clean debris inside the drum 1, and can better observe the internal condition of the drum 1 through the inspection port 13 during stirring.

[0024] Example 2 Please see Figure 6-7 As shown in the first embodiment, as another implementation of the present invention, a stirring arm 7 is fixedly connected to the surface of the stirring rod 5. The stirring arm 7 is in an inclined state, and a blade 8 is fixedly connected to the surface of the stirring arm 7. During operation, the mixing arm 7 is fixedly connected to the surface of the mixing rod 5. When the mixing rod 5 rotates, it drives the mixing arm 7 to rotate. The mixing arm 7 is in an inclined state, which can play a pushing role during mixing, causing the concrete to move laterally and making the mixing more uniform. The surface of the mixing arm 7 is fixedly connected to the blade 8. During mixing, the blade 8 plays the role of cutting solids and preventing concrete from clumping together. Together with the inclined roller 1, it can achieve a very good mixing effect.

[0025] A hydraulic rod 17 is rotatably connected to the surface of the base 10. The end of the hydraulic rod 17 away from the base is rotatably connected to the surface of the roller 1. There are two hydraulic rods 17, which are symmetrically designed and located on both sides of the roller 1. During operation, the tilt and height of the roller 1 can be adjusted via the hydraulic rod 17, which facilitates feeding and discharging.
