Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a recycled concrete aggregate mixing device with quantitative discharge function. Background Technology

[0002] To save resources, recycled concrete aggregate is usually thoroughly mixed with other materials using a recycled concrete aggregate mixing device to produce recycled concrete. The cost of recycled aggregate is relatively low. Using a recycled concrete aggregate mixing device to produce recycled concrete can reduce raw material costs and improve economic efficiency while ensuring concrete quality. In addition, it can realize on-site treatment and reuse of construction waste, reducing waste transportation costs and treatment fees, further saving costs.

[0003] Existing recycled concrete aggregate mixing devices simply mix and remix the materials before discharging them, and only measure the material quantity by vehicle load, lacking specific quantitative discharge function.

[0004] An existing patent (publication number: CN214293749U) discloses a recycled concrete aggregate mixing device with a quantitative discharge function. The discharge device includes a storage box located at the right end of the conveying box and a quantitative discharge mechanism located in the storage box. The quantitative discharge mechanism includes a discharge shaft rotatably located on the front and rear outer walls of the storage box, a discharge cylinder located on the outer wall of the discharge shaft, and a discharge motor located on the rear outer wall of the storage box for driving the discharge shaft.

[0005] To address the aforementioned issues, while existing patents can convey and seal materials through a quantitative discharging mechanism, in actual use, this solution cannot perform precise weighing of the materials, thus failing to improve the accuracy of quantitative measurement. Summary of the Invention

[0006] The purpose of this invention is to provide a recycled concrete aggregate mixing device with a quantitative discharge function, which can weigh the material during the conveying process to avoid errors and maintain the accuracy of the quantitative measurement of the material weight, thereby solving the problems mentioned in the background art.

[0008] The weighing mechanism includes a drive motor, which is embedded in the lower part of the outer wall of the mixing device body. The power output end of the drive motor is connected to a first bidirectional threaded rod. A sliding frame is slidably connected to the outer wall of the first bidirectional threaded rod. An abutment plate is rotatably connected inside the sliding frame. A support plate is rotatably connected to one end of the abutment plate that protrudes from the sliding frame. A pressure weighing device is embedded inside the support plate. A weighing block protrudes from the inside of the pressure weighing device. A support frame is fixedly installed on the top of the weighing block. A first support rod protrudes from one side of the first bidirectional threaded rod on the inner wall of the sliding frame.

[0009] Preferably, the sliding frame is threadedly connected to the first bidirectional threaded rod, and the sliding frame and the first support rod form a sliding structure.

[0010] Preferably, the support plate and the contact plate form a rotating structure, and the contact plate and the sliding frame form a rotating structure.

[0011] Preferably, limit blocks are fixedly installed on both sides of the outer wall of the storage shell, and limit grooves are formed on the outer wall of the main body of the mixing device at the positions corresponding to the limit blocks.

[0012] Preferably, a closing mechanism is provided on one side of the rubber sleeve above the storage shell. The closing mechanism includes a first transmission component, which is movably connected to one end of a first bidirectional threaded rod that passes through the main body of the mixing device. A transmission rod extends out from the inside of the first transmission component. A second transmission component is fixedly installed on the upper part of the outer wall of the transmission rod, and a second bidirectional threaded rod is fixedly installed on one end of the outer wall of the second transmission component.

Detailed Implementation

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A recycled concrete aggregate mixing device with quantitative discharge function includes a mixing device body 1. A placement trough 2 is provided below the mixing device body 1. A receiving shell 3 extends through the placement trough 2. A rubber sleeve 5 extends through the top of the receiving shell 3. A guide hopper 4 extends through the inner outer wall of the receiving shell 3. A weighing mechanism 6 is provided below the receiving shell 3. The weighing mechanism 6 includes a drive motor 601, which is embedded in the lower part of one side of the outer wall of the mixing device body 1. The power output end of the drive motor 601 is connected to a first bidirectional threaded rod 602. A sliding frame 603 is slidably connected to the outer wall of the first bidirectional threaded rod 602. An abutment plate 604 is rotatably connected inside the sliding frame 603, and the abutment plate 604 extends through one end of the sliding frame 603 and rotates. A support plate 605 is connected, and a pressure weighing device 606 is embedded inside the support plate 605. A weighing block 607 extends out from inside the pressure weighing device 606. A support frame 608 is fixedly installed on the top of the weighing block 607. A first support rod 609 extends out from one side of the first bidirectional threaded rod 602 on the inner wall of the sliding frame 603. The sliding frame 603 is threadedly connected to the first bidirectional threaded rod 602. A sliding structure is formed between the sliding frame 603 and the first support rod 609. A rotating structure is formed between the support plate 605 and the contact plate 604. A rotating structure is formed between the contact plate 604 and the sliding frame 603. Limiting blocks 8 are fixedly installed on both sides of the outer wall of the housing 3. A limiting groove 7 is opened on the outer wall of the mixing device body 1 at the position corresponding to the limiting block 8.

[0029] By adopting the above technical solution, the mixing device body 1 conveys materials to the receiving shell 3 through the rubber sleeve 5, and guides them to accumulate below the guide hopper 4 for easy subsequent unloading. Under normal conveying and non-weighing conditions, the limiting groove 7 supports the limiting block 8, thereby supporting and bearing the receiving shell 3. When weighing is required, the drive motor 601 drives the first bidirectional threaded rod 602, thereby pushing the two sliding frames 603, which slide stably along the first support rod 609. The two sliding frames 603 are connected by a rotating shaft and a contact plate 604. The device can adjust its angle to raise the support plate 605, allowing the pressure weighing device 606 to support the weighing block 607. The support frame 608 then stably supports the storage shell 3 for weighing. The net weight of the material is obtained by subtracting the weight of the storage shell 3 and other components from the obtained data. This allows for accurate weighing of the material and maintains the quantitative accuracy during discharge. The rubber sleeve 5, through its own flexibility and elasticity, penetrates a considerable distance into the storage shell 3, thus ensuring that the conveying process is maintained during the movement of the storage shell 3 without being affected or damaged.

[0030] Specifically, such as Figure 4 and Figure 5 As shown, a closing mechanism 9 is provided on one side of the rubber sleeve 5 above the housing shell 3. The closing mechanism 9 includes a first transmission component 901, which is movably connected to one end of the first bidirectional threaded rod 602 that passes through the main body 1 of the mixing device. A transmission rod 902 extends out of the inside of the first transmission component 901. A second transmission component 903 is fixedly installed on the upper part of the outer wall of the transmission rod 902. A second bidirectional threaded rod 904 is fixedly installed on one end of the outer wall of the second transmission component 903. The closing mechanism 9 also includes a clamping plate 905, which is slidably connected to the outer wall of one end of the second bidirectional threaded rod 904 that passes through the placement groove 2. A second support rod 906 extends out from one side of the second bidirectional threaded rod 904 inside the clamping plate 905. The second bidirectional threaded rod 904 is threadedly connected to the clamping plate 905. A sliding structure is formed between the clamping plate 905 and the second support rod 906.

[0031] By adopting the above technical solution, when the weighing reaches the required quantitative amount, the drive motor 601 continues to work, causing the first bidirectional threaded rod 602 to continue rotating. Through the first transmission component 901, transmission rod 902, and second transmission component 903, the second bidirectional threaded rod 904 rotates. The first transmission component 901 and the second transmission component 903 are in the form of worm gears, thereby causing the second bidirectional threaded rod 904 to rotate and drive the two clamping plates 905 to slide relative to each other. By sliding along the second support rod 906, the stability of the sliding process is improved, so as to clamp the rubber sleeve 5 and completely seal the mixing device body 1 and the receiving shell 3, preventing material from seeping or falling, thus affecting the accuracy of quantitative discharge.

[0032] Working principle: The main body 1 of the mixing device consists of multiple components, including a feeding hopper, a mixing chamber, a power system, a control system, and a mixing assembly. It can fully mix materials, which is existing technology and will not be elaborated further here. Simultaneously, the material is guided by the rubber sleeve 5 into the receiving shell 3 for storage. The guide hopper 4 at the bottom of the receiving shell 3 is cylindrical to facilitate material accumulation. The material is discharged through an internally installed adapter motor and screw conveyor shaft, which is existing and conventional technology. The limiting groove 7 limits and supports the limiting block 8, ensuring the receiving shell 3 is supported in a non-weighing state. The drive motor 601 drives the first bidirectional threaded rod 602, causing the two sliding frames 603 to slide relative to each other and stably along the first support rod 609. The sliding frames 603 and the support plate 605 are rotatably connected to the contact plate 604 via a rotating shaft. By rotating the support plate 605 upwards, the pressure weighing device 606 (JHHM-H series, selected according to different weight requirements) pushes the weighing block 607, causing the support frame 608 to support the storage shell 3 and rise along the placement groove 2 for accurate weighing. The limiting groove 7 is larger than the limiting block 8 to prevent the limiting block 8 from being attached and causing force dispersion, thus affecting the accuracy of the data. When the weight reaches the standard, the drive motor 601 continues to work, causing the first bidirectional threaded rod 602 to rotate. Through the worm gear combination of the first transmission component 901 and the second transmission component 903, the second bidirectional threaded rod 904 is rotated in conjunction with the transmission rod 902, thereby causing the two clamping plates 905 to slide relative to each other and stably slide along the second support rod 906, clamping the rubber sleeve 5 to prevent the material from being conveyed inside the mixing device body 1.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
