[0028] In order to better understand the technical content of the present utility model, specific embodiments are provided below, and the present utility model will be further described in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Refer to Figures 1 to 4 , the present utility model provides a device for modulating recycled concrete, a feed hopper 1, a crushing box 2 is provided at the bottom of the feed hopper 1, a plurality of rolling rollers 3 are provided in the crushing box 2, one end of the rolling roller 3 is rotatably connected to the inner side wall of the crushing box 2, and the other end extends outside the crushing box 2 and is connected to a power mechanism arranged outside the crushing box 2. The bottom of the crushing box 2 is connected to a treatment box 4, a filtering component is provided in the treatment box 4, one end of the filtering component is hinged to the inner side wall of the treatment box 4, and the other end is flexibly connected to the inner side wall of the treatment box 4. An opening 5 is provided on one side of the treatment box 4 for the filtering component to output impurities; a stirring part is provided below the filtering component, and the stirring part is used for receiving recycled aggregates and stirring and modulating them with cement and water.

[0031] Specifically, the feed hopper 1 is used to receive old concrete. During the continuous receiving process, the old concrete falls into the crushing box 2, and the rolling roller 3 is driven by the power mechanism to crush the old concrete into small particle recycled aggregates and metals or woods wrapped in the old concrete. After being crushed, the old concrete passes through the rolling roller 3 and falls on the filtering component to filter out metal or wood impurities. The impurities can fall out from the opening 5, and the remaining small particle recycled aggregates on the filtering component pass through the filtering component and fall into the stirring part. The stirring part stirs and modulates the recycled aggregates with cement and water. Compared with the traditional technology, the present utility model filters the recycled aggregates rolled in the crushing box 2 by adopting the filtering component, separates the impurities on the filtering component, obtains high-quality recycled aggregates, and finally stirs and modulates the recycled aggregates with cement and water to obtain high-quality recycled concrete.

[0032] Preferably, the filtering component includes: a filter plate 6, a filter screen 7 is arranged inside the filter plate 6, one side of the filter plate 6 is hinged to the inner side wall of the treatment box 4 through a hinge 8, the bottom of the other side of the filter plate 6 is connected to a power spring 9, and the other end of the power spring 9 is connected to the top surface of a balance plate 10 arranged inside the treatment box 4; a first motor 11 is arranged behind the treatment box 4, the output end of the first motor 11 is connected to a rotating shaft 12, two cams 13 are sleeved on the rotating shaft 12, the rotating shaft 12 extends into the treatment box 4, and among them, the cam 13 contacts the bottom surface of the filter plate 6.

[0033] During filtering, the first motor 11 rotates the cam 13. Due to the characteristics of the cam 13, the filter plate 6 is continuously bounced up and down, so that the recycled aggregates pass through the filter screen 7, and the impurities move along the downward inclined direction of the filter plate 6 when bouncing up and down. Moreover, when the filter plate 6 moves up and down, the power spring 9 is stretched, so that the power spring 9 accumulates elastic potential energy, increasing the bouncing degree of the filter plate 6 up and down and further enhancing the filtering effect.

[0034] Preferably, the power mechanism includes: a second motor 14, and a power box 15 covering the output end of the second motor 14. The output end of the second motor 14 is connected to a driving gear 16. Inside the power box 15, there are a first driven gear 17 and a second driven gear 18. The driving gear 16 is meshed with both the first driven gear 17 and the second driven gear 18. The first driven gear 17 and the second driven gear 18 are respectively connected to two rolling rollers 3 arranged in the crushing box 2. A heat dissipation plate 19 is provided at the bottom of the second motor 14.

[0035] When the second motor 14 rotates, it drives the driving gear 16 to rotate, thereby driving the first driven gear 17 and the second driven gear 18 to rotate. Among them, the rotation directions of the first driven gear 17 and the second driven gear 18 are opposite, so that the double rolling rollers 3 connected thereto can generate a pressing force on the old concrete during operation, and the old concrete is rolled into small particle recycled materials, improving the quality of the recycled aggregate.

[0036] In addition, a heat dissipation plate 19 is provided at the bottom of the second motor 14 for heat dissipation, so that the second motor 14 can continuously dissipate heat during long-term operation, extending its service life. Among them, the heat dissipation plate 19 can be arranged on the top surface of the processing box 4 to further support the stable operation of the second motor 14.

[0037] Preferably, a dust-proof plate 20 is provided at the opening 5. The top of the dust-proof plate 20 is rotatably connected to the outer side surface of the processing box 4. The bottom surface of the opening 5 is inclined, and its bottom surface is located above the bottom of the dust-proof plate 20.

[0038] The dust-proof plate 20 is used to prevent a large amount of soot from being discharged outside the processing box 4 during the filtering process of the filtering component, which affects the environment. When impurities need to be processed, the dust-proof plate 20 is opened, and the impurities fall out from the opening 5 for the next step of processing.

[0039] In addition, during actual use, the dust-proof plate 20 is connected to the outer side of the processing box 4 through a damping hinge 8, and the dust-proof plate 20 can be fixed at an angle of 10° with the opening 5 according to requirements, which is convenient for the impurities to fall out and prevents too many impurities from concentrating on the filter plate 6, affecting the work. At the same time, a wet cloth (not shown) needs to be arranged on the periphery of the dust-proof plate 20 to stick the dust scattered in the processing box 4.

[0040] It should be noted that the bottom surface of the opening 5 is inclined, and its length direction is located directly below the filter plate 6, so that the impurities filtered by the filter plate 6 cannot fall onto the balance plate 10, avoiding affecting the normal operation of the power spring 9.

[0041] Preferably, the stirring part includes: a third motor 21 and a stirring roller 22. A plurality of stirring blades 23 are provided on the outer peripheral surface of the stirring roller 22. The third motor 21 is arranged on the right side surface of the processing box 4. The output end of the third motor 21 is connected to the stirring roller 22, and the other end of the stirring roller 22 is rotatably connected to the inner side wall of the processing box 4.

[0042] Heat the cement and water in the treatment tank 4, and then mix with recycled aggregates. Drive the stirring roller 22 by the third motor 21 to drive the stirring blades 23 to stir and mix evenly into new concrete. After the modulation is completed, a flowable and plastic mixture is generated, which can easily fill the formwork during pouring. Subsequently, the old concrete is tested before crushing for its physical and mechanical properties to ensure compliance with the standards.

[0043] In addition, the treatment tank 4 is provided with an outlet (not shown) for facilitating the removal of the new concrete.

[0044] Embodiment 2

[0045] See Figure 1 , as another preferred embodiment, a base plate 24 is provided on the side of the treatment tank 4, a support frame 25 is provided on the top surface of the base plate 24, an electric push rod 26 is provided on the top of the support frame 25, and the electric push rod 26 is connected to a pressing mechanism provided on the bottom surface of the support frame 25. The pressing mechanism can slide on the inner wall of the feed hopper 1.

[0046] The support frame 25 is used to be in a right-angled shape, and its top is used to support the electric push rod 26 to drive the pressing mechanism to ensure the stability of the electric push rod 26. When the electric push rod 26 is driven, the pressing mechanism extends downward into the feed hopper 1, so that the pressing mechanism further compresses the old concrete to be crushed, which is beneficial for the crushing roller 3 to crush the old concrete.

[0047] Furthermore, the pressing mechanism includes a pressing plate 27. Symmetric cavities 28 are provided inside the pressing plate 27. A partition plate is provided between the cavities 28. Telescopic springs are connected to both the left and right sides of the partition plate. The other ends of the two telescopic springs are respectively connected to a first telescopic plate 29 and a second telescopic plate 30. The first telescopic plate 29 and the second telescopic plate 30 can both slide in the cavity 28.

[0048] Exemplarily, when the pressing mechanism extends downward into the feed hopper 1, since the diameter of the feed hopper 1 gradually becomes narrower, the first telescopic plate 29 and the second telescopic plate 30 continuously compress the telescopic springs and slide in the cavity 28 in the next process, so as to adapt to the change in the diameter of the feed hopper 1 and ensure the practicability of the pressing mechanism. Similarly, when the electric push rod 26 lifts the pressing mechanism, the diameter of the feed hopper 1 gradually becomes larger in the upward direction inside the feed hopper 1, so that the telescopic springs slide the first telescopic plate 29 and the second telescopic plate 30 outward in the cavity 28.

[0049] Furthermore, rollers 31 are provided at one end of the first telescopic plate 29 and the second telescopic plate 30 close to the inner wall of the feed hopper 1 to facilitate the up and down movement of the first telescopic plate 29 and the second telescopic plate 30 in the feed hopper 1.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
