[0001] This utility model relates to the field of concrete technology, and in particular to a concrete mixing device. Background Technology

[0002] Concrete is an engineering composite material made by mixing cementitious materials, aggregates and water in a specific ratio. As one of the most important basic materials in the modern construction field, concrete plays an irreplaceable role in civil engineering construction due to its excellent engineering performance and wide range of applications. Standard concrete usually uses cement as cementitious material, sand and stone as aggregates, and adds appropriate amounts of water and necessary admixtures and additives, and is made after scientific proportioning and thorough mixing.

[0003] Most existing concrete mixing equipment uses a single mixing method, with a fixed mixing rod and blades. This makes it difficult to achieve uniform mixing of concrete raw materials, which may affect the quality of the concrete.

[0004] Therefore, those skilled in the art have provided a concrete mixing device to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete mixing device that uses a mixing mechanism to achieve comprehensive mixing of concrete raw materials, ensuring uniform mixing of various raw materials and improving the quality of concrete.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A concrete mixing device includes a main body, a mixing mechanism inside the main body, the mixing mechanism including a motor and a rotating shaft, a drive shaft fixedly mounted on the output end of the motor, a connecting block fixedly mounted on one side of the drive shaft, an upper sliding groove opened at the upper end of the rotating shaft, a connecting groove opened on one side of the upper sliding groove, a lower sliding groove opened at the lower end of the rotating shaft, a fixing column fixedly mounted at the lower end inside the main body, a groove opened on the outside of the fixing column, and a fixing block fixedly mounted at the lower end inside the rotating shaft. Multiple stirring rods are fixedly installed on the outside of the rotating shaft, and a connecting column is axially slidably installed inside the stirring rod.

The other end of the connecting column has a first limiting part and a second limiting part is provided at the free end of the stirring rod. A spring is provided between the first limiting part and the second limiting part, and the spring is sleeved on the connecting column.

[0010] Furthermore, a discharge pipe is fixedly installed at the lower end of the main body of the equipment, and the motor is externally fixedly installed at the upper end of the inner part of the main body of the equipment.

[0011] Furthermore, a control panel is fixedly installed at the front end of the main body of the device, and multiple support legs are fixedly installed at the lower end of the main body of the device.

[0012] Furthermore, a breathable mesh is fixedly provided on the upper end of the main body of the equipment, and a feed inlet is fixedly provided on the upper end of the main body of the equipment away from the breathable mesh.

[0013] This utility model has the following beneficial effects: 1. The concrete mixing equipment proposed in this utility model, when mixing concrete, the drive shaft drives the connecting block to rotate, the connecting block drives the rotating shaft to rotate, the rotation of the rotating shaft causes the fixed block to slide in the groove outside the fixed column, thereby causing the rotating shaft to slide up and down inside the main body of the equipment, so that the mixing rod outside the rotating shaft slides up and down at the same time during the rotation, thereby expanding the mixing range, reducing the mixing dead corners, and improving the mixing efficiency.

[0017] 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.

[0018] Reference Figures 1-5 One embodiment provided by this utility model: A concrete mixing device includes a main body 1, a mixing mechanism 6 is provided inside the main body 1, the mixing mechanism 6 includes a motor 601 and a rotating shaft 603, a drive shaft 612 is fixedly provided at the output end of the motor 601, a connecting block 614 is fixedly provided on one side of the drive shaft 612, an upper sliding groove 611 is provided at the upper end of the rotating shaft 603, a connecting groove 613 is provided on one side of the upper sliding groove 611, a lower sliding groove 605 is provided at the lower end of the rotating shaft 603, a fixing column 606 is fixedly provided at the lower end inside the main body 1, a groove 607 is provided on the outside of the fixing column 606, and a fixing block 608 is fixedly provided at the lower end inside the rotating shaft 603. The fixing block 608 is externally slidably disposed inside the groove 607, the fixing column 606 is externally slidably disposed inside the lower groove 605, the connecting block 614 is externally slidably disposed inside the connecting groove 613, and the drive shaft 612 is externally slidably disposed inside the upper groove 611. Multiple stirring rods 604 are fixedly installed on the outside of the rotating shaft 603. A connecting post 609 is axially slidably installed inside the stirring rod 604. The connecting post 609 extends to the outside of the stirring rod 604 and is fixedly connected to the stirring blade 602. The other end of the connecting post 609 has a first limiting part and a second limiting part is provided at the free end of the stirring rod 604. A spring 610 is provided between the first limiting part and the second limiting part and is sleeved on the connecting post 609. Specifically, when the motor 601 operates, its output drive shaft 612 rotates accordingly, causing the connecting block 614 to rotate synchronously. The rotating shaft 603 is inside the connecting groove 613 and can slide up and down. The connecting groove 613 is in a vertical state. Since the connecting block 614 is externally slidably set inside the connecting groove 613, the rotation of the connecting groove 613 will cause the rotating shaft 603 to be driven to rotate synchronously. At the same time, the fixing block 608 fixed inside the rotating shaft 603 will slide stably in the groove 607 outside the fixing column 606. The groove 607 is inclined, so that the rotating shaft 603 can continuously slide up and down inside the main body 1 of the equipment. The lower end of the rotating shaft 603 is in contact with the outside of the fixing column 606. During the rotation of the rotating shaft 603, the stirring rod 604 fixed outside it not only makes a circular motion around the axis of the rotating shaft 603, but also slides up and down with the rotating shaft 603, thereby improving the mixing efficiency and enabling the concrete raw materials to be mixed more thoroughly in a shorter time.

[0019] Furthermore, the motor 601 has an adjustable speed function, allowing operators to flexibly adjust the motor 601 speed according to different concrete mix proportions and mixing process requirements. The adjustable speed motor 601 is a mature and publicly available technology, therefore, its specific structure and working principle will not be elaborated upon in this article. When the motor 601 is running, the mixing rod 604 rotates and mixes the concrete raw materials inside the main body 1 of the equipment. During this process, due to the centrifugal force, the connecting column 609 inside the mixing rod 604 overcomes the elastic force of the spring 610 and slides outward along the inside of the mixing rod 604. The sliding of the connecting column 609 will drive the mixing blade 602, which is fixedly connected to it, to extend outward, thereby increasing the working radius of the mixing blade 602 and further expanding the mixing range, enabling the mixing blade 602 to mix efficiently. During maintenance, a suitable harmless lubricant can be added to the connecting groove 613 and the groove 607 to improve the service life of the device.

[0020] Reference Figures 1-2 The lower end of the main body 1 is fixedly provided with a discharge pipe 7, the motor 601 is externally fixedly provided inside the upper end of the main body 1, the front end of the main body 1 is fixedly provided with a control panel 4, the lower end of the main body 1 is fixedly provided with multiple support legs 5, the upper end of the main body 1 is fixedly provided with a breathable net 2, and the upper end of the main body 1 away from the breathable net 2 is fixedly provided with a feed inlet 3. Specifically, when concrete raw materials enter the equipment body 1 through the feed inlet 3, the mixing mechanism 6 mixes and stirs them. After the mixing is completed, the finished concrete will be discharged from the discharge pipe 7 at the lower end of the equipment body 1. The ventilated net 2 at the upper end of the equipment body 1 facilitates ventilation of the motor 601. The control panel 4 is used to control the start and stop of the motor 601 and adjust the mixing speed. It is easy to operate. Multiple support legs 5 provide stable support for the equipment body 1 and improve stability.

[0021] Working principle: When in use, concrete raw materials are first put into the feed port 3 at the top of the main body 1. Then, the motor 601 inside the main body 1 is started to move, which in turn drives the drive shaft 612 at its output end to rotate the connecting block 614. Since the connecting block 614 slides inside the connecting groove 613, when the connecting block 614 is driven to rotate, it will drive the rotating shaft 603 to rotate. The rotation of the rotating shaft 603 will cause the fixing block 608 at the lower end inside to slide in the groove 607 outside the fixing column 606, which will cause the rotating shaft 603 to slide up and down continuously inside the main body 1. This will cause the stirring rod 604 outside the rotating shaft 603 to slide up and down during the rotation, thereby improving the mixing efficiency. Secondly, when the motor 601 is running, the stirring rod 604 will stir the concrete inside the main body 1 of the equipment. Under the action of centrifugal force, the connecting column 609 will slide inside the stirring rod 604, causing the spring 610 to be squeezed and contracted, thereby driving the stirring blade 602 to extend outward and stir the concrete.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
