Description

Technical Field

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

[0002] In construction, the demand for concrete is very large, and concrete mixers are needed to mix the concrete. Concrete mixers are very common on construction sites.

[0003] The most common type of concrete mixer in the existing technology is the drum mixer, which uses the rotation of the mixing drum and the blades inside the drum to carry the concrete material to a high place and then let it fall freely. The mixture is achieved by the gravity of the material. However, the existing concrete mixers have some shortcomings in use: the blades inside the drum are not easy to separate from the mixing drum for cleaning after use. Over time, the concrete will stick to the blades or the inner wall of the drum, affecting the service life of the mixer. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that the blades of existing mixers are not easily separated from the mixing drum for cleaning after use, which affects the service life of the mixer.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A concrete mixing device for building construction includes a support frame, a mixing drum fixedly connected to the upper end of the support frame, a discharge valve provided at the bottom of the mixing drum, a fixing block fixedly connected to the side wall of the mixing drum, a rotating device provided on the lower end face of the fixing block and in the fixing block, a beam plate fixedly connected to the upper end of the rotating device, an inverted L-shaped bracket fixedly connected to the upper end of the beam plate, a lifting device provided on the bracket, a base connected to the lifting device, and a mixing scraper device provided on the base and extending through the beam plate into the mixing drum.

[0006] Furthermore, the lifting device includes a motor, which is fixedly connected to the top wall of the support. The output end of the motor is connected to a lead screw and rotates on the beam plate. An ear plate is fixedly connected to the side wall of the base and threadedly connected to the lead screw.

[0007] Furthermore, the stirring and scraping device includes a second motor, which is fixed to the upper end of the base. The output end of the second motor is provided with a rotating shaft. Connecting rods are arranged in a circular array on the side wall of the rotating shaft. A stirring paddle is provided on the connecting rod. A scraper is provided at the end of the connecting rod and can fit against the inner wall of the stirring cylinder.

[0008] Furthermore, the rotary device includes a limiting plate, which is fixed to the lower end face of the fixed block. A rotary column is rotatably arranged in the fixed block and the limiting plate through a bearing. The upper end of the rotary column is fixed to the beam plate, and a gear two is fixed to the lower end of the rotary column. A motor three is fixed inside the limiting plate, and the output end of the motor three is connected to a gear one and meshes with a gear two.

[0009] Furthermore, a cylinder cover is fixedly connected to the rotating shaft, and when the cylinder cover covers the mixing cylinder, the scraper fits precisely against the inner wall of the mixing cylinder.

[0010] The beneficial effects achieved by adopting the above-described structure are as follows:

[0011] 1. This utility model, by setting up a lifting device, a motor drives the lead screw to rotate, the lead screw drives the ear plate to rise and fall, and the ear plate drives the base to rise and fall, thereby raising the stirring scraper device out of the stirring drum for easy internal rinsing of the stirring drum.

[0012] 2. This utility model, by setting up a rotary device, has a motor driving gear one to rotate, gear one meshing with gear two to rotate, gear two driving the rotary column to rotate, and the rotary column driving the beam plate to rotate. This allows the stirring scraper device to be moved to one side of the stirring drum for rinsing. This allows the stirring drum and stirring scraper device to be cleaned independently, resulting in a more thorough and clean cleaning and effectively extending their service life.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] like Figure 1-4 This utility model discloses a concrete mixing device for construction, including a support frame 1, a mixing drum 2 fixedly connected to the upper end of the support frame 1, a discharge valve 3 provided at the bottom of the mixing drum 2, a fixing block 4 fixedly connected to the side wall of the mixing drum 2, a rotating device 5 provided at the lower end face of the fixing block 4 and in the fixing block 4, a beam plate 6 fixedly connected to the upper end of the rotating device 5, an inverted L-shaped bracket 7 fixedly connected to the upper end of the beam plate 6, a lifting device 8 provided on the bracket 7, a base 9 connected to the lifting device 8, and a mixing scraper device 10 provided on the base 9, which extends through the beam plate 6 into the mixing drum 2.

[0021] like Figure 1-3 The lifting device 8 includes a motor 11, which is fixed to the top wall of the support 7. The output end of the motor 11 is connected to a lead screw 12 and rotates on the beam plate 6. An ear plate 13 is fixed to the side wall of the base 9 and threadedly connected to the lead screw 12. The base 9 is lifted by rotating the lead screw 12, thereby separating the stirring and scraping device 10 from the stirring drum 2 for cleaning.

[0022] like Figure 1-3The mixing and scraping device 10 includes a second motor 14, which is fixed to the upper end of the base 9. The output end of the second motor 14 is provided with a rotating shaft 15. Connecting rods 16 are arranged in a circular array on the side wall of the rotating shaft 15. A mixing paddle 17 is provided on the connecting rod 16. A scraper 18 is provided at the end of the connecting rod 16 and can fit against the inner wall of the mixing drum 2. A drum cover 24 is fixed to the rotating shaft 15. When the drum cover 24 covers the mixing drum 2, the scraper 18 fits against the inner wall of the mixing drum 2. By rotating the rotating shaft 15, the mixing paddle 17 is driven to rotate. The mixing paddle 17 can mix the concrete in the mixing drum 2 evenly. At the same time, the scraper 18 can scrape the inner wall of the mixing drum 2 clean to prevent the concrete from solidifying on the inner wall of the mixing drum 2.

[0023] like Figure 1-4 The rotary device 5 includes a limiting plate 19, which is fixed to the lower end face of the fixed block 4. A rotary column 20 is rotatably mounted in the fixed block 4 and the limiting plate 19 via a bearing. The upper end of the rotary column 20 is fixed to the beam plate 6, and the lower end of the rotary column 20 is fixed to a gear 21. A motor 22 is fixed inside the limiting plate 19. The output end of the motor 22 is connected to a gear 23 and meshes with the gear 21. By the gear 23 meshing with the gear 21, the rotary column 20 drives the beam plate 6 to rotate, thereby transferring the stirring and scraping device 10 to one side of the stirring drum 2, and independently cleaning the stirring paddle 17, scraper 18 and connecting rod 16.

[0024] In practical use, the concrete raw materials to be mixed are added into the mixing drum 2. Then, by starting the motor 11, the lead screw 12 rotates and drives the ear plate 13 to rise and fall. The ear plate 13 drives the base 9 to rise and fall, and the drum cover 24 also falls down until the drum cover 24 covers the mixing drum 2. At this time, the scraper 18 is in contact with the inner wall of the mixing drum 2. By starting the motor 14, the rotating shaft 15 drives the connecting rod 16 to rotate. The connecting rod 16 drives the mixing paddle 17 and the scraper 18 to rotate synchronously. The mixing paddle 17 can mix the concrete raw materials in the mixing drum 2, while the scraper 18 scrapes and cleans the inner wall of the mixing drum 2 to prevent the concrete from setting.

[0025] After mixing, the concrete material in the mixing drum 2 can be discharged by opening the discharge valve 3. After discharge, the lifting device 8 is used to drive the drum cover 24, scraper 18, and mixing paddle 17 to move upward and detach them from the upper end of the mixing drum 2. At the same time, the starting motor 22 and gear 23 mesh with gear 21 to rotate. Gear 21 drives the rotating column 20 to rotate, and the rotating column 20 drives the beam plate 6 to rotate. In this way, the mixing scraper device 10 rotates to one side of the mixing drum 2, which can independently clean the mixing drum 2 and also independently rinse the mixing scraper device 10.

[0026] When rinsing the mixing drum 2 and the mixing scraper device 10, manual rinsing with a handheld water gun is sufficient. The motor 11, motor 24 and motor 32 in this application are all equipped with control switches. The switches can be set on the fixed block 4 or the mixing drum 2, or they can be set as remote control switches. These are all existing technologies and will not be described in detail here.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
