Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a durable cement-stabilized crushed stone vibration mixing device. Background Technology

[0002] Cement-stabilized crushed stone is made by using graded crushed stone as aggregate, filling the voids in the aggregate with a certain amount of cementitious material and sufficient mortar volume, and then spreading and compacting it according to the principle of interlocking. As a semi-rigid material, it is widely used in highway pavement base construction due to its strong integrity, high load-bearing capacity, high stiffness, and good water stability. Vibration mixing effectively combines macroscopic convection and microscopic diffusion, truly achieving microscopic uniformity in cement-stabilized crushed stone. Vibration mixing is an economical and effective method for mechanically enhancing the mixing process.

[0003] Patent publication number CN208742440U discloses a vibration mixing durable cement-stabilized crushed stone device, which achieves vibration mixing by installing two vibration motors at the bottom of the box to drive the box to vibrate. However, in actual use, since the vibration is generated by the box itself, it can often only produce a vibration effect on the cement-stabilized crushed stone near the side wall of the box, and cannot effectively transmit the vibration effect to the cement-stabilized crushed stone in the more central part of the box. The vibration effect is not uniform enough. In addition, when the box is driven to vibrate by the vibration motor, not only is the noise generated large, but the energy consumption is also large, resulting in a high production cost of cement-stabilized crushed stone.

[0010] Preferably, the transmission assembly includes a second rotating rod, one end of which is fixedly connected to the center point of the end face of the rotating disk away from the transmission rod, and the other end of which passes through the side wall of the stirring rod and is fixedly connected to a first bevel gear. Two symmetrical first bevel gears are connected to a second bevel gear, which is fixedly sleeved on the side wall of the fixed rod. The inner ring of a second sealing bearing is fixedly connected to the side wall of the second rotating rod, and the second sealing bearing is fixedly installed in a first through hole, which is opened on the side wall of the stirring rod.

[0011] Preferably, the driving component is a drive motor, which is fixedly installed at the center of the top surface of the housing. The top and bottom walls of the housing are symmetrically provided with second through holes. A third sealed bearing is fixedly installed in the second through hole.

Through the transmission component in the vibration box and the fixed rod in the first cavity, the transmission component drives the striking component to strike the inner wall of the vibration box, causing the vibration box itself to vibrate. Since several vibration boxes are distributed within the box cavity and rotate synchronously with the stirring rod, the contact area with the cement-stabilized crushed stone inside the box is increased, thereby improving the vibration uniformity of the cement-stabilized crushed stone and increasing production efficiency.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Reference Figure 1-5 The present invention provides a durable cement-stabilized crushed stone vibration mixing device, including a housing 1, a mixing rod 2 rotatably connected to the housing 1 via a driving component, a plurality of mixing blades 3 fixedly installed at equal intervals on the mixing rod 2, a vibration mechanism is provided between each pair of adjacent mixing blades, a first cavity 4 is opened in the mixing rod 2, and a fixing rod 5 is provided in the first cavity 4.

[0029] The vibration mechanism includes a vibration box 6 symmetrically fixed to the outer wall of the stirring rod 2. The end of the vibration box 6 near the stirring rod 2 is open. A striking component is installed inside the vibration box 6. The two sides of the striking component are detachably connected to the inner wall of the vibration box 6. One end of the striking component is connected to a transmission component. The other end of the transmission component passes through the side wall of the stirring rod 2 and is connected to the fixed rod 5.

[0030] The driving component drives the stirring rod 2 to rotate, and several sets of stirring blades 3 rotate synchronously to stir the cement-stabilized crushed stone in the box 1. Several vibration mechanisms are set on the stirring rod 2. When the stirring rod 2 rotates, the vibration box 6 in the vibration mechanism rotates synchronously with the stirring rod 2. The transmission component in the vibration box 6 generates a transmission effect with the fixed rod 5 in the first cavity 4, which in turn drives the striking component to strike the inner wall of the vibration box 6, causing the vibration box 6 to vibrate. Since there are several vibration boxes 6 distributed in the inner cavity of the box 1 and they rotate synchronously with the stirring rod 2, the contact area with the cement-stabilized crushed stone in the box 1 can be increased, thereby improving the vibration uniformity of the cement-stabilized crushed stone.

[0031] Further optimization of the design: The striking component includes a rotating disk 7 rotatably connected to the inner cavity of the vibration box 6. One end face of the rotating disk 7 is connected to the transmission component. One end of the transmission rod 8 is fixedly connected to the outer ring of the other end face of the rotating disk 7. The other end of the transmission rod 8 is inclined downward and fixedly connected to the fixed end of the universal ball 9. The rotating end of the universal ball 9 is fixedly connected to the center point of the side wall of the first rotating rod 10. The two ends of the first rotating rod 10 are respectively fixedly connected to the inner ring of the first sealed bearing 11. The two first sealed bearings 11 are respectively fixedly installed on the inner top surface and inner bottom surface of the vibration box 6. The side wall of the first rotating rod 10 is symmetrically fixedly connected to the abutment plate 12. The two abutment plates 12 cover the universal ball 9 and a section of the transmission rod 8. The inner wall of the two abutment plates 12 is in contact with the side wall of the transmission rod 8. The side wall of the abutment plate 12 away from the transmission rod 8 is movably connected to the striking element. The striking element is detachably connected to the inner side wall of the vibration box 6.

[0032] The transmission assembly drives the rotating disk 7 to rotate, which in turn drives the transmission rod 8 to rotate. Since the transmission rod 8 is inclined and one end is fixed to the outer ring of the rotating disk 7, the transmission rod 8 can achieve a conical cross-section movement trajectory, thereby driving the two abutment plates 12 to achieve a left-right swaying effect. The first rotating rod 10 is used to fix the position of the two abutment plates 12, and the position of the first rotating rod 10 can be fixed by setting the first sealed bearing 11. By fixing the rotating end of the universal ball 9 to the first rotating rod 10, the universal ball 9 fixes the end position of the transmission rod 8 away from the rotating disk 7, so that while the transmission rod 8 and the universal ball 9 rotate relative to each other, the transmission rod 8 drives the two abutment plates 12 to sway left and right. Thus, during the left-right swaying of the two abutment plates 12, the two striking parts can continuously strike the inner wall of the vibration box 6, thereby causing the vibration box 6 to vibrate itself.

[0033] The design is further optimized so that the striking component includes a support rod 13 fixed to the side wall of the abutment plate 12, one end of an elastic rod 14 fixed to the top side wall of the support rod 13, the other end of the elastic rod 14 fixed to the side wall of the striking head 15, the striking end of the striking head 15 being detachably connected to the inner side wall of the vibration box 6, and the bottom end of the striking head 15 being detachably connected to an elastic component.

[0034] The striking point of the striking head 15 is preferably the center of the inner side wall of the vibration box 6, which is conducive to improving the overall vibration transmission effect of the vibration box 6. The elastic rod 14 is supported by the support rod 13. The elastic rod 14 can deform. When the two abutment plates 12 swing left and right, they can shake the elastic rod 14 and, together with the elastic element, make the striking head 15 shake, thus achieving the effect of multiple strikes.

[0035] The optimized solution includes a groove 16 formed on the side wall of the abutment plate 12, a sliding rod 17 slidably connected in the groove 16, one end of the sliding rod 17 extending out of the groove 16 and fixedly connected to a spring plate 18, the top surface of the spring plate 18 being detachably connected to the bottom end of the striking head 15, and a first spring 19 fixedly connected between the bottom surface of the spring plate 18 and the side wall of the abutment plate 12, the first spring 19 covering the sliding rod 17.

[0036] When the striking head 15 shakes, the bottom end of the striking head 15 contacts and presses down on the spring plate 18. The spring plate 18 moves down under the guidance of the sliding rod 17. At this time, the first spring 19 is compressed and generates elastic force, which in turn causes the spring plate 18 to push the striking head 15, increasing the striking force and shaking speed of the striking head 15, thereby increasing the striking frequency. It should be noted that the maximum extension length of the first spring 19 is less than the length of the sliding rod 17, so that the bottom end of the sliding rod 17 is always located in the groove 16, avoiding the phenomenon of dislodging.

[0037] The scheme is further optimized. The transmission component includes a second rotating rod 20. One end of the second rotating rod 20 is fixedly connected to the center point of the end face of the rotating disk 7 away from the transmission rod 8. The other end of the second rotating rod 20 passes through the side wall of the stirring rod 2 and is fixedly connected to a first bevel gear 21. Two symmetrical first bevel gears 21 are connected to a second bevel gear 22. The second bevel gear 22 is fixedly sleeved on the side wall of the fixed rod 5. The inner ring of a second sealing bearing 23 is fixedly connected to the side wall of the second rotating rod 20. The second sealing bearing 23 is fixedly installed in a first through hole, which is opened on the side wall of the stirring rod 2.

[0038] When the vibrating box 6 rotates synchronously with the stirring rod 2, it drives the second rotating rod 20 to rotate synchronously. Then, through the meshing transmission of the first bevel gear 21 and the second bevel gear 22, the second rotating rod 20 rotates on its own, thereby realizing the rotation of the rotating disk 7. Furthermore, the position of the second rotating rod 20 can be fixed by the setting of the second sealing bearing 23, which not only does not interfere with the rotation of the second rotating rod 20, but also enables the second rotating rod 20 to rotate synchronously with the stone mixing rod 2.

[0039] In a further optimized design, the driving component is a drive motor 26, which is fixedly installed at the center of the outer top surface of the housing 1. The top and bottom walls of the housing 1 are symmetrically provided with second through holes, and third sealed bearings 27 are fixedly installed in the second through holes. The top and bottom ends of the stirring rod 2 are respectively fixedly connected to the inner rings of the two third sealed bearings 27, and the top end of the stirring rod 2 passes through the third sealed bearings 27 and is fixedly connected to the output shaft of the drive motor 26.

[0040] The stirring rod 2 is rotated by the drive motor 26, and the position of the stirring rod 2 can be fixed by two third sealing bearings 27, thereby improving the sealing effect of the box 1.

[0041] The design is further optimized by fixing a support plate 28 at the center of the bottom surface of the box 1. The support plate 28 covers the second through hole, and the bottom end of the fixing rod 5 extends out of the first cavity 4 and is fixed to the support plate 28.

[0042] By setting a support plate 28 to fix the bottom end of the fixed rod 5, the fixed rod 5 remains fixed when the stirring rod 2 rotates, thereby achieving the meshing transmission effect of the first bevel gear 21 and the second bevel gear 22.

[0043] To further optimize the design, two feed inlets 29 are provided on the top wall of the housing 1. The two feed inlets 29 are located on both sides of the drive motor 26. One end of the feed inlet 29 is connected to the inner cavity of the housing 1, and the other end is connected to the feed hopper 30. The feed hopper 30 is fixedly installed on the outer top surface of the housing 1.

[0044] By setting up the feed hopper 30, it is easy to put cement-stabilized crushed stone into the inner cavity of the box 1.

[0045] To further optimize the design, two discharge ports are opened on the bottom wall of the box 1. The two discharge ports are located on both sides of the support plate 28. A discharge pipe 31 is fixedly connected inside the discharge port. One end of the discharge pipe 31 is connected to the inner cavity of the box 1, and the other end extends out of the discharge port to connect with the outside. A solenoid valve 32 is fixedly installed on the discharge pipe 31.

[0046] The discharge pipe 31 facilitates the discharge of cement-stabilized crushed stone from the box 1, and the electromagnetic valve 32 can control the opening and closing of the discharge pipe 31.

[0047] Furthermore, several support legs 40 are fixed to the bottom surface of the box 1.

[0048] Working principle: Cement-stabilized crushed stone is fed into the box 1 through the feed hopper 30. Then, the drive motor 26 is started to drive the stirring rod 2 to rotate, so that the stirring blades 3 stir the cement-stabilized crushed stone in the box 1. When the stirring rod 2 rotates, the first bevel gear 21 and the second bevel gear 22 mesh and transmit power, causing the second rotating rod 20 to rotate. In turn, the rotating disk 7 drives the transmission rod 8 to rotate, realizing the left and right swing of the two abutment plates 12. Then, the two striking heads 15 continuously strike the inner wall of the vibrating box 6, causing the vibrating box 6 to vibrate. Thus, the vibration effect generated by multiple vibrating boxes 6 is evenly transmitted to the cement-stabilized crushed stone in the box 1, thereby achieving efficient vibration mixing.

[0049] Example 2

[0050] Reference Figure 6-7 The difference between this embodiment and Embodiment 1 is that two first horizontal plates 33 are vertically arranged inside the housing 1, and the two first horizontal plates 33 are respectively fixedly connected to several vibration boxes 6 on both sides (e.g., Figure 6 As shown), a first sliding cavity 34 is provided in the first horizontal plate 33. The end of the first sliding cavity 34 away from the vibration box 6 is connected to one end of the second sliding cavity 35. The other end of the second sliding cavity 35 is connected to the outside. A second horizontal plate 36 is slidably connected in the second sliding cavity 35. One end of the second horizontal plate 36 extends out of the second sliding cavity 35 and several burrs 37 are fixed on the end face. A limiting plate 38 is fixed to the other end of the second horizontal plate 36. The limiting plate 38 is slidably connected in the first sliding cavity 34, and the width of the limiting plate 38 is greater than the width of the second sliding cavity 35. Several third springs 39 are fixed between the end face of the limiting plate 38 away from the second horizontal plate 36 and the end face of the first sliding cavity 34 away from the second sliding cavity 35.

[0051] With this configuration, when several vibrating boxes 6 vibrate, the vibration can be transmitted to the first horizontal plate 33, causing the first horizontal plate 33 and the second horizontal plate 36 to vibrate as well. This further improves the uniformity of vibration mixing of cement-stabilized crushed stone. Furthermore, the two first horizontal plates 33 rotate synchronously with the vibrating box 6, allowing the burrs 37 on the two second horizontal plates 36 to scrape away the cement-stabilized crushed stone adhering to the inner wall of the box 1, thus improving production efficiency and reducing the waste rate of cement-stabilized crushed stone. At the same time, the force of the third spring 39 allows the burrs on the second horizontal plate 36 to adhere to the inner wall of the box 1, improving the cleaning effect. The limiting plate 38 prevents the second horizontal plate 36 from coming out of the second sliding cavity 35, and the end face of the second horizontal plate 36 with burrs 37 is beveled, making it easy to insert cement-stabilized crushed stone into contact with the inner wall of the box 1.
