[0003] Currently, concrete mixing devices are frequently used by operators during house construction. However, while existing concrete mixing devices have basic mixing functions, the mixing rod and blades are fixed, so mixing can only be performed in the same position, which reduces the mixing efficiency of the device and causes inconvenience to operators. Therefore, improvements are needed. Utility Model Content
[0004] The purpose of this invention is to address the above problems. This invention provides a concrete proportioning device for building construction, which has the advantage of mixing by mixing from top to bottom.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete proportioning device for building construction, comprising a base, wherein there are two bases, and a support block and a rectangular block are respectively fixedly installed on the top of the two bases. A movable block and a removable block are respectively movably connected inside the support block and the rectangular block. The tops of the movable block and the removable block pass through the support block and the rectangular block and extend to the outside of the top of the support block and the rectangular block. A mixing tank is fixedly connected between the movable block and the removable block. A protective cover is movably connected to the top of the mixing tank, and a connecting block is fixedly installed on the back of the protective cover. The other end of the connecting block extends to the back of the mixing tank and is movably connected to the back of the mixing tank. A first motor is fixedly installed on the back of the movable block. A bidirectional threaded screw is fixedly sleeved on the other end of the output shaft of the first motor.

The top of the limit block passes through the long block and extends to the bottom of the slider and is fixedly connected to the bottom of the slider.
[0006] As a preferred embodiment of this utility model, a second motor is fixedly installed inside the protective cover, and a stirring rod is fixedly sleeved at the other end of the output shaft of the second motor. The bottom end of the stirring rod passes through the protective cover and the stirring tank in sequence and extends into the interior of the stirring tank, and stirring blades are fixedly installed on its outer surface. The outer surface of the stirring rod is movably connected to the interior of the stirring tank.
[0007] As a preferred embodiment of the present invention, a discharge port is fixedly installed inside the bottom end of the mixing tank, and the bottom end of the discharge port passes through the mixing tank and extends to the outside of the bottom end of the mixing tank.

[0021] 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.
[0022] like Figures 1 to 6As shown, this utility model provides a concrete proportioning device for building construction, including a base 1. There are two bases 1. A support block 2 and a rectangular block 23 are fixedly installed on the top of each base 1. A movable block 3 and a movable block 24 are movably connected inside the support block 2 and the rectangular block 23, respectively. The tops of the movable blocks 3 and 24 pass through the support block 2 and the rectangular block 23 and extend to the outside of their respective tops. A mixing tank 4 is fixedly connected between the movable blocks 3 and 24. A protective cover 5 is movably connected to the top of the mixing tank 4. A connecting block 6 is fixedly installed on the back of the protective cover 5. The other end of the connecting block 6 extends to the back of the mixing tank 4 and is movably connected to it. A first motor 7 is fixedly installed on the back of the movable block 24. The other end of the output shaft of the first motor 7 is fixedly sleeved... There is a bidirectional threaded screw 8, and sliders 9 are threadedly sleeved on both sides of the outer surface of the bidirectional threaded screw 8. A long rod 10 is hinged to the top of the slider 9, and the other end of the long rod 10 is hinged to the outside of the connecting block 6. A long block 12 is fixedly installed at the bottom of the back of the mixing tank 4. A limit block 11 is movably connected inside the long block 12. The top of the limit block 11 passes through the long block 12 and extends to the bottom of the slider 9 and is fixedly connected to the bottom of the slider 9. When the operator starts the first motor 7, the bidirectional threaded screw 8 will rotate, which will cause the two sliders 9 to move towards each other. In turn, the two sliders 9 will drive the two long rods 10 to rotate, which will push the connecting block 6 and the protective cover 5 to move upward as a whole. This will increase the mixing efficiency of the concrete during the subsequent mixing process.
[0023] The protective cover 5 houses a second motor 13, and the other end of the output shaft of the second motor 13 is fixedly connected to a stirring rod 14. The bottom end of the stirring rod 14 passes through the protective cover 5 and the mixing tank 4 and extends into the interior of the mixing tank 4. A stirring blade 15 is fixedly installed on its outer surface. The outer surface of the stirring rod 14 is movably connected to the interior of the mixing tank 4. When the operator starts the second motor 13, the stirring rod 14 and the stirring blade 15 will rotate. Due to the design of the protective cover 5, the second motor 13 is well protected.
[0024] The bottom of the mixing tank 4 is fixedly equipped with a discharge port 16. The bottom of the discharge port 16 passes through the mixing tank 4 and extends to the outside of the bottom of the mixing tank 4. Due to the design of the discharge port 16, the concrete that has been mixed inside the mixing tank 4 can be discharged to the outside through the discharge port 16.
[0025] The mixing tank 4 has two feed inlets 17 fixedly installed on the left and right sides of the top. The two feed inlets 17 are the same size. Due to the design of the two feed inlets 17, the operator can add concrete raw materials and water into the mixing tank 4 through the two feed inlets 17 respectively.
[0026] Among them, springs 18 are fixedly connected to the left and right sides of the bottom of the movable block 3 and the movable block 24. There are four springs 18. The bottom ends of the four springs 18 are fixedly connected to the bottom ends of the inner surfaces of the support block 2 and the rectangular block 23, respectively. Due to the design of the four springs 18, the movement of the movable block 3 and the movable block 24 can be well reset.
[0027] The third motor 19 is fixedly installed on the right side of the support block 2, and the other end of the output device of the third motor 19 is fixedly sleeved with the rotating shaft 20; when the operator starts the third motor 19, the rotating shaft 20 will rotate.
[0028] The left end of the rotating shaft 20 is fixedly connected to a hollow block 21, and a round shaft 22 is movably installed inside the hollow block 21. The other end of the round shaft 22 is fixedly connected to the outside of the moving block 3. When the rotating shaft 20 rotates, the inner surface of the hollow block 21 will squeeze and push the outer surface of the round shaft 22, thereby causing the round shaft 22 to drive the moving block 3, the mixing tank 4 and the moving block 24 to move upward.
[0029] Working principle and usage process of this utility model:
[0030] First, the operator pours the proportioned sand, stone, and water into the mixing tank 4 through the two feed inlets 17. Then, the operator starts the second motor 13 and the first motor 7. The operation of the second motor 13 causes the stirring rod 14 and stirring blade 15 to rotate, allowing the stirring blade 15 to mix the proportioned sand, stone, and water inside the mixing tank 4. Meanwhile, the operation of the first motor 7 causes the bidirectional threaded screw 8 to rotate, causing the two sliders 9 to move in opposite directions. This, in turn, pushes the two long rods 10, causing them to rotate. This causes the two long rods 10 to push the connecting block 6 and the protective cover 5 upwards. Then, the operator uses the first motor 7 to return the bidirectional threaded screw 8 and the two sliders 9 to their initial state. At this time, the two long rods 10 will pull the connecting block 6 and the protective cover 5 downwards. This cycle will allow the mixing blades 15 to mix the sand, stone and water inside the mixing tank 4, thereby improving its mixing efficiency. After mixing is completed, the operator opens the discharge port 16 to discharge the concrete inside the mixing tank 4.
[0031] While the above structure significantly increases mixing efficiency, a large amount of concrete remains on the inner surface of the mixing tank 4 after the concrete is discharged. At this point, the operator activates the third motor 19, causing the rotating shaft 20 and hollow block 21 to rotate. This causes the inner surface of the hollow block 21 to press against the outer surface of the round shaft 22, which in turn drives the moving block 3, mixing tank 4, and movable block 24 upwards. During this upward movement, the four springs 18 are in a stretched state. The operator then uses the third motor 19 to return the rotating shaft 20 and hollow block 21 to their initial state. The restoring force of the four springs 18 causes the moving block 3 to drive the mixing tank 4 and movable block 24 downwards. This repeated motion vibrates the entire mixing tank 4, causing the concrete adhering to its inner surface to fall off, thus reducing concrete waste and further enhancing the application of the device.
