Description

Technical Field

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

[0002] As one of the most important structural materials in modern construction engineering, the production quality of concrete directly affects the safety, durability, and economy of the project. With the continuous improvement of the performance requirements of concrete in the construction industry, traditional manual batching and mixing methods can no longer meet the needs of high-precision and high-efficiency production. Therefore, the research and development and application of quantitative addition mixing equipment for concrete production has become an important direction for the industry's technological upgrading.

[0003] In existing technologies, conventional concrete production quantitative addition mixing devices use sensors for measurement. However, existing sensors may malfunction after a long period of use. These malfunctions cannot be detected by workers in a timely manner, leading to inaccurate measurement and waste of concrete. Therefore, it is necessary to improve the concrete production quantitative addition mixing device to solve the above problems. Utility Model Content

[0004] To overcome the problem that sensors may malfunction after prolonged use, and that these malfunctions may not be detected by staff in a timely manner, leading to inaccurate measurement and wasted concrete.

[0005] The technical solution of this utility model is as follows: a concrete production quantitative addition mixing device, including a base and a discharge device, and a cylinder fixedly connected to the base. The cylinder is equipped with a mixing component for mixing concrete inside the cylinder. The discharge device is fixedly connected to the base, and a first support is fixedly connected to the discharge device. A metering blade is rotatably connected to the first support. A second support is fixedly connected to the discharge device, and a baffle plate is rotatably connected to the second support. A rotating shaft is fixedly connected to the discharge device, and a top rod is rotatably connected to the rotating shaft. A rope wheel is fixedly connected to the metering blade, and a metering rope is fixedly connected between the rope wheel and the top rod. The flowing concrete causes the metering blade to rotate and rewind the metering rope. Then, the top rod rotates, causing the baffle plate to lose its support and thus rotate to block the flow of concrete.

[0006] Preferably, a first limiting block for positioning the top rod is fixedly connected to the discharge device, a second limiting block for positioning the top rod is fixedly connected to the discharge device, and a baffle plate is fixedly connected to the discharge device to prevent concrete from splashing onto the rope wheel and the metering rope.

[0007] Preferably, an end cap is fixedly connected to the cylinder, a feed funnel is fixedly connected to the cylinder, a feed baffle is slidably connected to the feed funnel, a control panel is fixedly connected to the cylinder, and an observation baffle is rotatably connected to the end cap.

[0008] Preferably, a limiting groove is provided on the cylinder, and a discharge baffle is slidably connected inside the limiting groove.

[0009] Preferably, the feed funnel has a matching groove at the corresponding position of the feed baffle, and the feed baffle slides inside the groove, blocking the feed of the feed funnel when the feed baffle is closed.

[0010] Preferably, the mixing assembly includes a motor fixedly connected to the cylinder, a drive wheel fixedly connected to the output end of the motor, a stirring rod rotatably connected between the cylinder and the end cover, a driven wheel fixedly connected to the stirring rod, and a belt connecting the drive wheel and the driven wheel.

[0011] Preferably, the stirring rod is provided with four straight blades and four inclined blades, and the four straight blades and four inclined blades are evenly distributed from top to bottom on the stirring rod.

[0012] The beneficial effects of this utility model are:

[0013] The quantitative addition of concrete is achieved by adjusting the number of turns of the measuring rope wound on the rope wheel and the number of turns of the rope wheel when winding the measuring rope. The measuring rope and rope wheel are simple to manufacture and low in cost. When the measuring rope and rope wheel are damaged, the on-site staff can replace them immediately, making maintenance simple, measurement accurate and reliable, and preventing concrete waste.

[0014] By using belt drive, the device is protected against overload. When there are hard foreign objects inside the cylinder, the power transmission can be interrupted by belt slippage and breakage, effectively protecting the device and making it more reliable and less prone to serious damage.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-6 This utility model provides an embodiment of a concrete production quantitative addition mixing device, including a base 1 and a discharge device 2, and a cylinder 12 fixedly connected to the base 1. A mixing component for mixing the concrete inside the cylinder 12 is installed on the cylinder 12. The discharge device 2 is fixedly connected to the base 1, and a first support 22 is fixedly connected to the discharge device 2. A metering blade 23 is rotatably connected to the first support 22. A second support 24 is fixedly connected to the discharge device 2, and a baffle plate 25 is rotatably connected to the second support 24. A rotating shaft 29 is fixedly connected to the discharge device 2, and a top rod 27 is rotatably connected to the rotating shaft 29. A rope wheel 212 is fixedly connected to the metering blade 23, and a metering rope 211 is fixedly connected between the rope wheel 212 and the top rod 27. The flowing concrete causes the metering blade 23 to rotate and retract the metering rope 211. Then, the top rod 27 rotates, causing the baffle plate 25 to lose its support and thus rotate, blocking the flow of concrete. 7 is used to raise and lower the baffle plate 25. When the baffle plate 25 is raised, concrete can flow out through the discharge device 2. When the baffle plate 25 is lowered, the flowing concrete pushes the baffle plate 25 to rotate, so that the baffle plate 25 and the discharge device 2 are tightly matched, thus blocking the concrete and stopping its flow. The wall height of the discharge devices 2 on both sides of the baffle plate 25 is flush with the bottom surface of the cylinder 12 to prevent concrete from overflowing from both sides. The rope wheel 212 is manually rotated, and the length of the measuring rope 211 wound on the rope wheel 212 is calculated by the number of rotations to adjust the amount of concrete flowing out. The more rotations of the measuring rope 211 wound on the rope wheel 212, the less concrete flows out, and vice versa. When the measuring rope 211 wound on the rope wheel 212 reaches its maximum, the measuring rope 211 is taut, thereby pulling the top rod 27, lowering the baffle plate 25, and stopping the concrete flow.

[0024] Please see Figures 1-5In this embodiment, a first limiting block 28 for positioning the top rod 27 is fixedly connected to the discharge device 2, a second limiting block 210 for positioning the top rod 27 is fixedly connected to the discharge device 2, and a baffle plate 213 is fixedly connected to the discharge device 2. The baffle plate 213 prevents concrete from splashing onto the rope wheel 212 and the metering rope 211, and prevents concrete from getting stuck between the rope wheel 212 and the metering rope 211. When the concrete solidifies, it will seriously affect the performance of the rope wheel 212 and the metering rope 211. The first limiting block 28 and the second limiting block 210 restrict the rotation of the top rod 27, ensuring that the top rod 27 rotates within a specified range. An end cap 13 is fixedly connected to the cylinder 12, a feeding funnel 14 is fixedly connected to the cylinder 12, and a feeding baffle 15 is slidably connected to the feeding funnel 14. A control panel 16 is fixedly connected to the top, and an observation baffle 17 is rotatably connected to the end cover 13. The end cover 13 protects the internal structure of the cylinder 12 and prevents foreign objects from entering the cylinder 12. Concrete enters the cylinder 12 from the feed funnel 14. When the device is running, the situation inside the cylinder 12 can be observed by rotating the observation baffle 17. A limit groove is opened on the cylinder 12, and a discharge baffle 26 is slidably connected inside the limit groove. When the discharge baffle 26 is removed, the concrete will flow from the cylinder 12 to the discharge device 2. The feed funnel 14 has a matching groove at the corresponding position of the feed baffle 15, and the feed baffle 15 slides inside the groove. When the feed baffle 15 is closed, the feed funnel 14 is blocked from feeding. The feed baffle 15 is only opened when feeding to prevent foreign objects from entering the cylinder 12 during operation.

[0025] Please see Figure 6 In this embodiment, the mixing assembly includes a motor 3 fixedly connected to the cylinder 12, a drive wheel 33 fixedly connected to the output end of the motor 3, a mixing rod 35 rotatably connected between the cylinder 12 and the end cap 13, a driven wheel 34 fixedly connected to the mixing rod 35, and a belt 32 drivingly connecting the drive wheel 33 and the driven wheel 34. When the mixing rod 35 rotates, it thoroughly mixes the concrete. The belt 32 provides overload protection for the device. When a hard object enters the cylinder 12, the mixing rod 35 gets stuck with the object, and the belt 32 will slip or break, thus interrupting the power transmission, and the mixing rod 35 will stop rotating. The mixing rod 35 is provided with four straight blades and four inclined blades, which are evenly distributed from top to bottom on the mixing rod 35. The rotation of the straight blades and the inclined blades makes the concrete flow more vigorously in the cylinder 12, and the concrete is mixed more evenly.

[0026] During operation, remove the feed baffle 15, open the feed inlet of the feed funnel 14, pour in concrete, insert the feed baffle 15, and start the motor 3 using the control panel 16. The motor 3 drives the drive wheel 33 to rotate, and the drive wheel 33 transmits power to the driven wheel 34 through the belt 32. The driven wheel 34 drives the mixing rod 35 to rotate, and the rotating mixing rod 35 mixes the concrete. Rotate the observation baffle 17 to observe the mixing of the concrete inside the cylinder 12. When the concrete mixing is complete, close the observation baffle 17 and proceed according to the requirements. The required quantity is obtained by removing a metering rope 211 of appropriate length from the rope wheel 212 and removing the discharge baffle 26. Under the action of gravity and the mixing rod 35, the concrete flows into the discharge device 2. The flowing concrete drives the metering blade 23 to rotate, which in turn drives the rope wheel 212 to rotate. The rotating rope wheel 212 winds up the metering rope 211. When the metering rope 211 is taut, it pulls the top rod 27 to rotate, causing the baffle plate 25 to lose its support and thus rotate to block the flow channel of the concrete, stopping the concrete flow.

[0027] Through the above steps, the concrete drives the rope wheel 212 and the rotation of the rope wheel 212, thereby pulling the top rod 27, causing the baffle plate 25 to be lowered, blocking the flow of concrete, and thus measuring the concrete. This solves the problem that when the sensor has been used for too long, it will malfunction. This malfunction cannot be detected by the staff in time, which will lead to inaccurate measurement and waste of concrete.
