[0002] Concrete is a commonly used material in building construction. Concrete is made by mixing cement with water, sand, gravel, etc. Currently, it is mainly done by mixing equipment. The raw materials such as cement, sand, gravel and water are added to the mixing equipment and mixed to achieve the purpose of mixing.

[0003] Existing mixing devices mostly use straight cylindrical mixing drums, which easily accumulate material at the edges. This material is difficult for ordinary mixing devices to move, resulting in insufficient mixing of concrete, affecting the mixing effect, and reducing the practicality of the equipment. In addition, the outlets of existing mixing devices are mostly simple open-mouthed outlets, which make it difficult to control the discharge of concrete with different moisture levels, and the poor sealing can easily lead to liquid loss and carry away some material, reducing the mixing ratio of concrete.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1: See Figures 1 to 10 A concrete mixing device includes a mixing drum 1. Three support columns 3 are equidistantly arranged on the bottom surface of the mixing drum 1. A cover plate 4 is provided on the upper part of the mixing drum 1. An auxiliary mixing mechanism 5 is provided inside the mixing drum 1 at the lower end of the cover plate 4. A first transmission box 7 is provided in the middle of the bottom surface of the mixing drum 1. The auxiliary mixing mechanism 5 can prevent some materials from adhering and remaining in the corners of the mixing drum 1, affecting the mixing ratio of the materials inside the mixing drum 1. A discharge port is opened on the bottom surface of the mixing drum 1. A telescopic box 6 is provided inside the lower wall of the mixing drum 1 below the discharge port. A discharge mechanism 2 is provided at the lower end of the discharge port on the bottom surface of the mixing drum 1. A support plate 8 for supporting the installation of the cover plate 4 is provided on the upper part of the mixing drum 1. The discharge mechanism 2 can better control the discharge of the mixing drum 1. The telescopic box 6 can better block the discharge port and prevent water from seeping out of the discharge port and affecting the mixing quality of the concrete.

[0030] In this invention, the discharge mechanism 2 consists of a second transmission box 9 and a rectangular sleeve. The upper end of the rectangular sleeve has a vertical hole for connecting to the discharge port. A spiral discharge rod 10 is coaxially fixed to the second transmission motor shaft of the second transmission box 9. Spiral blades are provided on the outer side of the spiral discharge rod 10. Through the arrangement of the spiral discharge rod 10 and spiral blades in the discharge mechanism 2, the discharge of concrete can be better controlled. A feed inlet is provided on the upper part of the cover plate 4, and a feed hopper 12 is provided above the feed inlet. A baffle is hinged to the top of the feed hopper 12. Several water-spraying blocks 15 are evenly spaced on the bottom surface. A water supply pipe 11 for connecting the several water-spraying blocks 15 is provided on the upper part of the cover plate 4. The material can be added better through the setting of the feed hopper 12. The water-spraying blocks 15 and the water supply pipe 11 can spray water better to accelerate the mixing of materials and water and improve the mixing efficiency. A rotating baffle 13 is provided at the upper end of the cover plate 4. A limiting slide rail 14 for limiting the rotating baffle 13 is provided on the upper part of the cover plate 4. The rotating baffle 13 can better isolate the mixing drum 1 and reduce the splashing of dust materials.

[0031] In this invention, a rotating rod 16 is coaxially fixed to the first transmission motor shaft of the first transmission box 7. Three fixed rods 17 are horizontally and equidistantly arranged on the upper part of the rotating rod 16. Each fixed rod 17 is equipped with an inclined blade. Through the arrangement of the fixed rods 17 and the inclined blades, the concrete can be better stirred, and the concrete at the bottom can be turned over and stirred, resulting in more thorough mixing. The auxiliary stirring mechanism 5 consists of a rotary motor 18, a first scraper 19, and a second scraper 21. A first support block for abutting against the cover plate 4 is fixed to the upper top surface of the rotary motor 18. A second support block for pressing and limiting the rotating baffle 13 is fixed to the upper top surface of the first support block. The rotary motor 18... A first connecting plate is horizontally mounted on the shaft. A first scraper 19 is fixedly connected to the side end of the first connecting plate. The outer wall of the first scraper 19 abuts against the inner wall of the mixing drum 1. A second scraper 21 is horizontally mounted below the first scraper 19. A ball bearing for connecting the rotating rod 16 is provided at the end of the second scraper 21. Two inclined auxiliary mixing blocks 20 are equidistantly mounted on the inner side of the first scraper 19. By setting the first scraper 19 and the second scraper 21, the material on the side of the inner wall of the mixing drum 1 can be better delivered to the middle of the mixing drum 1 to participate in the mixing, so that the mixing of the material is more thorough. By setting the auxiliary mixing blocks 20, the mixing efficiency of concrete in the mixing drum 1 can be better improved.

[0032] In this invention, a first telescopic plate 23 is provided on the side of the telescopic box 6. An installation groove is formed inside the first telescopic plate 23, and a second telescopic plate 24 is provided in the installation groove. A first telescopic rod is provided on the side of the first telescopic plate 23 inside the telescopic box 6. A first telescopic control box 22 for controlling the first telescopic rod is provided on the bottom surface of the telescopic box 6. A second telescopic rod is provided on the side of the second telescopic plate 24 inside the telescopic box 6. A second telescopic control box for controlling the second telescopic rod is provided on the bottom surface of the telescopic box 6. The first telescopic control box 22 and the second telescopic control box are symmetrically installed on the bottom surface of the telescopic box 6. Through the arrangement of the first telescopic control box 22 and the second telescopic control box, better... The first telescopic plate 23 and the second telescopic plate 24 are controlled by the ground. The top surface of the side end of the first telescopic plate 23 is provided with a lifting sleeve, and the top surface of the inner side of the lifting sleeve is provided with a lifting spring 25. The upper end of the lifting spring 25 is fixedly connected to the inner top surface of the lifting sleeve. The upper wall of the telescopic box 6 is provided with a chamfer 26. By setting the lifting spring 25, the second telescopic plate 24 can be pushed to push out the lifting spring 25, so that the lifting sleeve is lifted to block the discharge port, preventing some material from falling into the upper discharge port of the second telescopic plate 24. The material here is difficult to participate in the mixing and is easy to solidify and block the discharge port. By setting the chamfer 26, the lifting sleeve, the first telescopic plate 23 and the second telescopic plate 24 can be better recovered.

[0033] Working principle: In this embodiment, the present invention also proposes a method for using a concrete mixing equipment, including the following steps:

[0034] Step 1: First, connect the power supply to each motor and electronic component through wires. Then, connect the water pump to the water pipe 11. Next, open the baffle hinged at the top of the feed hopper 12. Then, pour the material into the feed hopper 12. The rotating baffle 13 at the top of the cover plate 4 can be rotated to open and add material to the mixing drum 1. When adding powdered material, the rotating baffle 13 can be rotated to close the top of the mixing drum 1, so that when the powdered material is added to the feed hopper 12, no large amount of smoke or dust will be generated.

[0035] Step 2: While adding materials, start the water pump to add water to the water pipe 11. The water is dispersed by the water spray block 15 to form small water columns and water mist. The setting of the water spray block 15 and the water pipe 11 can better spray water to accelerate the mixing of materials and water and improve the stirring efficiency. Then start the first transmission box 7 and the rotary motor 18 to make the auxiliary stirring mechanism 5 and the rotating rod 16 rotate.

[0036] Step 3: The first scraper 19 on the auxiliary mixing mechanism 5 abuts against the inner wall of the mixing drum 1 and rotates, and the second scraper 21 abuts against the lower inner wall of the mixing drum 1. The arrangement of the first scraper 19 and the second scraper 21 can better deliver the material on the side of the inner wall of the mixing drum 1 to the middle of the mixing drum 1 to participate in the mixing, so that the material is mixed more thoroughly. The auxiliary mixing block 20 on the first scraper 19 can better improve the mixing efficiency of concrete in the mixing drum 1.

[0037] Step 4: The rotating rod 16 drives the three fixed rods 17 at the top to rotate together. The inclined blades on the fixed rods 17 can better turn the concrete at the bottom to the upper layer for circulation and mixing, so that the concrete is mixed more thoroughly. After the concrete is fully mixed, the first telescopic plate 23 is retracted. Before the first telescopic plate 23 retracts, the second telescopic control box controls the second telescopic plate 24 to retract. The retracted second telescopic plate 24 causes the lifting spring 25 to fall into the installation groove.

[0038] Step 5: Finally, the first telescopic plate 23 retracts. The setup of the first telescopic control box 22 and the second telescopic control box allows for better control of the first telescopic plate 23 and the second telescopic plate 24. The retracted first telescopic plate 23 cooperates with the chamfer 26, causing the lifting sleeve to be flattened and retracted into the telescopic box 6. Then, the second transmission box 9 is activated, causing the spiral discharge rod 10 and the spiral blades to rotate, thereby sending the concrete out of the rectangular sleeve. At this point, the use of the concrete mixing device is completed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
