[0033] An embodiment of the present invention provides a vibrating device for making pervious concrete test blocks, as Figure 1-11 shown, the vibrating device for making pervious concrete test blocks includes: a base 1 for placing a mold 60; an L-shaped support plate 2 fixedly installed on the top of the base 1, the L-shaped support plate 2 having a vertical section and a horizontal section, the vertical section being located on one side of the mold 60, and the horizontal section extending above the mold 60; a hoisting plate 3 slidably installed on the horizontal section of the L-shaped support plate 2 and correspondingly arranged with the mold 60 below; an oil cylinder 4 fixedly installed on the vertical section of the L-shaped support plate 2 for adjusting the vibrating position; a U-shaped connecting frame 5 fixedly installed on the output rod of the oil cylinder 4 and the hoisting plate 3; an L-shaped assembly frame 6 liftably installed on the hoisting plate 3 and arranged to avoid the U-shaped connecting frame 5; a vibrating mechanism provided on the L-shaped assembly frame 6 for vibrating the concrete in the mold 60; the vibrating mechanism includes a vibrating motor 7, an output main shaft 8, and a vibrating rod 9, the vibrating motor 7 being fixedly installed on the L-shaped assembly frame 6, the output main shaft 8 rotatably installed on the L-shaped assembly frame 6 and having its top end fixedly connected to the output shaft of the vibrating motor 7, and the vibrating rod 9 fixedly installed at the bottom end of the output main shaft 8 for extending into the mold 60 to vibrate the concrete.

[0034] In this embodiment, the device includes a base 1, an L-shaped support plate 2, a hoisting plate 3, an oil cylinder 4, a U-shaped connecting frame 5, an L-shaped assembly frame 6, and a vibrating mechanism. The base 1 stably places the mold 60, providing a basic support for the entire device. The L-shaped support plate 2 is cleverly fixed on the base 1 with its vertical and horizontal sections, being both stable and convenient for the installation and operation of subsequent components.

[0035] The hoisting plate 3 is slidably installed on the horizontal section of the L-shaped support plate 2 and is precisely corresponding to the mold 60 below. This design enables the vibrating position to be flexibly adjusted as needed. The oil cylinder 4 is fixed on the vertical section of the L-shaped support plate 2. Through its telescopic movement, in cooperation with the connection between the U-shaped connecting frame 5 and the hoisting plate 3, the precise adjustment of the overall position of the vibrating mechanism is achieved, thus solving the problem of limited position adjustment of traditional vibrating equipment.

[0036] The L-shaped mounting frame 6 is installed on the hoisting plate 3 in a liftable manner and is arranged to avoid the U-shaped connecting frame 5. This layout not only optimizes the space utilization but also ensures that the vibrating mechanism can be lifted and lowered smoothly to adapt to the vibrating requirements at different heights. The vibrating mechanism consists of a vibrating motor 7, an output main shaft 8, and a vibrating rod 9. The vibrating motor 7 provides power for the entire vibrating process, transmits the rotational motion to the vibrating rod 9 through the output main shaft 8, and the vibrating rod 9 directly extends into the mold 60 to vibrate the concrete efficiently.

[0037] The beneficial effects of the present invention are mainly reflected in the following aspects: Firstly, through the cooperation of the oil cylinder 4 and the hoisting plate 3, the flexible adjustment of the vibrating position is realized, solving the problem of uneven vibration of traditional equipment; Secondly, the liftable design of the L-shaped mounting frame 6 enables the vibrating mechanism to adapt to the vibrating requirements at different heights, improving the versatility and flexibility of the device; Finally, the efficient operation of the vibrating mechanism ensures the full vibration of the concrete and improves the quality of the test blocks. In summary, the present invention not only simplifies the vibrating steps in the production process of concrete test blocks but also significantly improves the production efficiency and quality of the test blocks.

[0038] In a further preferred embodiment of the present invention, a lifting mechanism is provided on the hoisting plate 3 for driving the L-shaped mounting frame 6 to lift and lower. The lifting mechanism includes a lifting screw 10, a lifting slider 11, and a lifting motor 12. The lifting screw 10 is rotatably installed on one side of the hoisting plate 3 where the L-shaped mounting frame 6 is located. The lifting slider 11 is threadedly sleeved on the lifting screw 10. The lifting slider 11 is fixedly connected to the L-shaped mounting frame 6 and is in slidable contact with the hoisting plate 3. The lifting motor 12 is fixedly installed on the hoisting plate 3, and sprockets 13 are fixedly installed on both the output shaft of the lifting motor 12 and the lifting screw 10, and the same chain 14 is sleeved on the two sprockets 13.

[0039] In this embodiment, a lifting mechanism composed of a lifting screw 10, a lifting slider 11, a lifting motor 12, sprockets 13, and a chain 14 is added to the hoisting plate 3. The lifting mechanism works in the following way: The lifting screw 10 is stably installed on one side of the hoisting plate 3 corresponding to the L-shaped mounting frame 6; The lifting slider 11 is threadedly sleeved on the lifting screw 10 and is closely matched with it to achieve vertical movement; The lifting slider 11 is fixedly connected to the L-shaped mounting frame 6 to ensure that the two lift and lower synchronously; At the same time, the lifting motor 12 is installed on the hoisting plate 3, and sprockets 13 are installed on both its output shaft and the lifting screw 10 and are connected by a chain 14 to form a transmission chain.

[0040] When the lifting motor 12 starts and rotates, through the transmission of the sprocket 13 and the chain 14, the lifting screw 10 is driven to rotate synchronously. Since the lifting slider 11 is threadedly connected to the lifting screw 10, the rotation of the lifting screw 10 will be converted into the linear motion of the lifting slider 11, thereby driving the L-shaped mounting bracket 6 and the vibrating mechanism thereon to move up and down. This design not only realizes the precise adjustment of the height of the vibrating mechanism, but also improves the stability and reliability of the lifting through mechanical transmission.

[0041] Through the setting of the lifting mechanism in this embodiment, the precise adjustment of the height of the vibrating mechanism can be realized, meeting the requirements of different test block heights and vibrating depths.

[0042] In a further preferred embodiment of the present invention, a transverse sliding opening 15 is provided on the horizontal section of the L-shaped support plate 2, the hoisting plate 3 can slidably penetrate through the transverse sliding opening 15, a bearing sliding plate 16 is fixedly installed in the transverse sliding opening 15, and the bearing sliding plate 16 can slidably penetrate through the hoisting plate 3.

[0043] In this embodiment, a transverse sliding opening 15 is specially designed on the horizontal section of the L-shaped support plate 2. This innovative design enables the hoisting plate 3 to slide horizontally along the transverse sliding opening 15, thereby realizing the precise adjustment of the vibrating mechanism in the horizontal direction. In addition, a bearing sliding plate 16 is fixedly installed inside the transverse sliding opening 15. The bearing sliding plate 16 further enhances the stability and load-bearing capacity of the hoisting plate 3 during the sliding process, and it can also slide relative to the hoisting plate 3 itself. This dual-sliding design improves the flexibility and durability of the entire structure.

[0044] During specific use, the operator can precisely adjust the horizontal and vertical positions of the vibrating mechanism relative to the mold 60 by controlling the sliding of the hoisting plate 3 in the transverse sliding opening 15. This adjustment method is not only convenient and fast, but also can ensure that the vibrating rod 9 can accurately extend into the specified position inside the mold 60 to effectively vibrate the concrete.

[0045] Through the design of the transverse sliding opening 15 and the bearing sliding plate 16 in this embodiment, the precise adjustment of the vibrating mechanism in the horizontal and vertical directions is realized, improving the accuracy and uniformity of vibration. The addition of the bearing sliding plate 16 provides additional support for the hoisting plate 3.

[0046] In a further preferred embodiment of the present invention, at least one roller bracket 17 is provided above and below the horizontal section of the L-shaped support plate 2. At least two of the roller brackets 17 are fixedly connected to the hoisting plate 3. Rotatable roller shafts 18 are installed on at least two of the roller brackets 17. Transverse movement stabilizing rollers 19 are rotatably sleeved on at least two of the roller shafts 18. At least two of the transverse movement stabilizing rollers 19 are respectively in rolling contact with the upper or lower part of the horizontal section of the L-shaped support plate 2.

[0047] In this embodiment, roller racks 17 are added both above and below the horizontal section of the L-shaped support plate 2. These roller racks 17 are fixedly connected to the lifting plate 3, ensuring the stability of the structure. A roller shaft 18 is rotatably installed on each roller rack 17, and a transverse movement stabilizing roller 19 is sleeved on the roller shaft 18. These transverse movement stabilizing rollers 19 are in rolling contact with the upper or lower part of the horizontal section of the L-shaped support plate 2.

[0048] The main function of this design is that when the lifting plate 3 slides within the transverse movement sliding opening 15, the transverse movement stabilizing rollers 19 can roll along the horizontal section of the L-shaped support plate 2, thereby providing a smooth and stable sliding support. Compared with the traditional sliding method, rolling contact can significantly reduce the frictional resistance, reduce the energy loss during the sliding process, and improve the smoothness and accuracy of the sliding at the same time.

[0049] In addition, the use of the transverse movement stabilizing rollers 19 can also disperse the weight and pressure generated by the lifting plate 3 and the vibrating mechanism carried thereon during the sliding process, reduce the wear on the L-shaped support plate 2 and the transverse movement sliding opening 15, and extend the service life of the equipment.

[0050] In a further preferred embodiment of the present invention, the widths of the L-shaped assembly frame 6, the vibrating motor 7, and the lifting slider 11 are all smaller than the distance between the two walls of the U-shaped connecting frame 5.

[0051] In this embodiment, due to the limited widths of the L-shaped assembly frame 6, the vibrating motor 7, and the lifting slider 11, this design enables the L-shaped assembly frame 6 and the vibrating mechanism thereon to be lifted and moved flexibly without being restricted by the U-shaped connecting frame 5. When it is necessary to adjust the position or height of the vibrating mechanism, the lifting slider 11 can slide smoothly within the U-shaped connecting frame 5, driving the L-shaped assembly frame 6 and the vibrating mechanism thereon to achieve precise positioning.

[0052] In a further preferred embodiment of the present invention, a rotating shaft 20 is rotatably installed at the center of the base 1. Above the base 1, there is a rotating disk 21 for placing the mold 60. The bottom of the rotating disk 21 is fixedly connected to the top end of the rotating shaft 20 with the same center of the circle.

[0053] In this embodiment, a rotatable rotating shaft 20 is introduced at the center of the base 1, and its upper end is firmly connected to the rotating disk 21. This design enables the rotating disk 21 to freely rotate around the axis of the rotating shaft 20, and the main function of the rotating disk 21 is to place and support the mold 60.

[0054] Specifically, when the operator needs to evenly vibrate the concrete in the mold 60, the rotating shaft 20 can be driven to rotate, thereby driving the rotating disk 21 and the mold 60 thereon to rotate synchronously. This rotational movement enables the concrete to be more comprehensively vibrated within the mold 60, avoiding the problem of uneven vibration that may occur in traditional fixed vibration.

[0055] In a further preferred embodiment of the present invention, a plurality of ball seats 22 are fixedly installed at the bottom of the rotating disk 21. The plurality of ball seats 22 are evenly arranged in a plurality of circular arrays. A ball 23 is movably embedded at the bottom of each of the plurality of ball seats 22, and the plurality of balls 23 can all roll along the top of the base 1.

[0056] In this embodiment, the bottom of the rotating disk 21 is not only fixedly connected to the top end of the rotating shaft 20, but also a plurality of ball seats 22 are ingeniously added. These ball seats 22 are evenly distributed in a plurality of circular arrays, providing additional support and stability for the rotating disk 21. A ball 23 is movably embedded at the bottom of each ball seat 22, and these balls 23 can freely roll along the top of the base 1.

[0057] This design further enhances the stability and smoothness of the rotating disk 21 during rotation. When the rotating shaft 20 drives the rotating disk 21 to rotate, the balls 23 roll on the top of the base 1, playing a role in reducing friction and energy consumption. At the same time, the uniform distribution and rolling characteristics of the balls 23 make the rotation of the rotating disk 21 more stable, reducing vibrations and noises caused by imbalance.

[0058] Combined with the above description of the rotating shaft 20 and the rotating disk 21, the design of the balls 23 in this embodiment further improves the overall performance of the device. It not only enables the rotating disk 21 to rotate more flexibly, but also extends the service life of the device and improves work efficiency by reducing friction and vibration. In addition, the easy maintainability of the balls 23 makes the maintenance and repair of the device simpler and faster.

[0059] In a further preferred embodiment of the present invention, a plurality of positioning screw holes 24 are formed in the rotating disk 21. The plurality of positioning screw holes 24 are evenly arranged in a plurality of circular arrays. A plurality of limit seats 25 are detachably installed on the rotating disk 21 by bolts for fixing the mold 60, and the limit seats 25 are arranged opposite to the corresponding positioning screw holes 24.

[0060] In this embodiment, a plurality of positioning screw holes 24 are formed in the rotating disk 21. These screw holes are evenly distributed in a plurality of circular arrays, providing an accurate position reference for the fixation of the mold 60. At the same time, a plurality of limit seats 25 are detachably installed on the rotating disk 21 by bolts. These limit seats 25 are arranged opposite to the corresponding positioning screw holes 24, jointly constituting a stable support and positioning system for the mold 60.

[0061] The ingenuity of this design lies in its flexibility and customizability. The operator can select a suitable limit seat 25 according to the actual size and shape of the mold 60, and fix it in the corresponding positioning screw holes 24 on the rotating disk 21 through bolts. In this way, no matter how the size and shape of the mold 60 change, stable support and accurate positioning can be obtained, ensuring the smooth progress of the vibrating process.

[0062] In addition, the design of the bolts being detachably installed also brings convenience for maintenance and replacement. When it is necessary to replace the mold 60 or perform equipment maintenance, the operator can easily disassemble and install the limit seat 25 without having to perform large-scale disassembly and reinstallation of the entire rotating disk 21.

[0063] In a further preferred embodiment of the present invention, the lifting screw 10 is connected to the lifting plate 3 by a bearing seat and bearing parts, and the lifting screw 10 penetrates through the lifting slider 11 in a threaded driving manner.

[0064] In this embodiment, a combined connection method of a bearing seat and bearing parts is adopted between the lifting screw 10 and the lifting plate 3. This design realizes the separation of rotational motion and linear motion, that is, the lifting screw 10 can rotate freely in the lifting plate 3 without being restricted by the movement of the lifting plate 3 itself.

[0065] At the same time, the lifting screw 10 penetrates through the lifting slider 11 in a threaded driving manner, which means that when the lifting screw 10 rotates, it will push the lifting slider 11 to move up and down along its thread track. This driving method is not only simple and reliable, but also can accurately control the moving distance of the lifting slider 11, thereby realizing precise adjustment of the height of the vibrating mechanism.

[0066] In a further preferred embodiment of the present invention, a plurality of legs are fixedly installed at the bottom of the base 1, and the plurality of legs are arranged in an array.

[0067] In this embodiment, the plurality of legs serve as a support structure between the base 1 and the ground. By arranging them in an array, the weight of the base 1 can be evenly distributed over a larger area, thereby reducing the pressure on the ground and avoiding ground damage or equipment tilt caused by excessive local pressure.

[0068] In order to further improve the use effect of the present device, in addition to the above-mentioned solutions, this solution also has the following embodiments:

[0069] In another embodiment of the present invention, a pulley 26 is fixedly installed at the bottom end of the rotating shaft 20. A first shaft seat 27 is fixedly installed on the vertical section of the L-shaped support plate 2. A longitudinal spline cylinder 28 is rotatably installed on the first shaft seat 27. A pulley 29 is fixedly installed at the bottom end of the longitudinal spline cylinder 28. The same synchronous belt 30 is sleeved on the pulley 29 and the pulley 26.

[0070] In this embodiment, the pulley 26 fixedly installed at the bottom end of the rotating shaft 20 and the pulley 29 at the bottom end of the longitudinally spline cylinder 28 rotatably installed in the first shaft seat 27 on the L-shaped support plate 2 are in transmission connection through the same synchronous belt 30. This design enables the rotational power of the rotating shaft 20 and the longitudinal spline cylinder 28 to be transmitted efficiently and stably.

[0071] In another embodiment of the present invention, a lifting slide opening 31 is formed on the vertical section of the L-shaped support plate 2. Anti-slip openings 32 are formed on both inner walls of the lifting slide opening 31. An anti-slip rectangular rod 33 is slidably installed in the anti-slip opening 32. A synchronous sleeve plate 34 is fixedly installed on the anti-slip rectangular rod 33. The synchronous sleeve plate 34 extends above the longitudinal spline cylinder 28 and the mold 60. A rectangular slide opening 35 is formed on one side of the synchronous sleeve plate 34. The L-shaped assembly frame 6 slidably extends into the rectangular slide opening 35. A second shaft seat 36 is fixedly installed on the top of the synchronous sleeve plate 34. A transverse spline cylinder 37 is rotatably installed on the second shaft seat 36. A third shaft seat 38 is fixedly installed on the top of the L-shaped assembly frame 6. A transverse spline shaft 39 is rotatably installed on the third shaft seat 38. The transverse spline shaft 39 extends into the transverse spline cylinder 37. Tapered gears 40 are fixedly installed on both the transverse spline shaft 39 and the output main shaft 8. The two tapered gears 40 are meshed with each other. A longitudinal transmission shaft 41 is rotatably installed on the synchronous sleeve plate 34. Tapered gears 42 are fixedly installed on both the longitudinal transmission shaft 41 and the transverse spline cylinder 37. The two tapered gears 42 are meshed with each other. A longitudinal spline shaft 43 is meshed and installed in the longitudinal spline cylinder 28. The top end of the longitudinal spline shaft 43 is fixedly connected to the bottom end of the longitudinal transmission shaft 41.

[0072] In this embodiment, first of all, the formation of the lifting slide opening 31 provides space for the lifting movement, while the design of the anti-slip opening 32 and the anti-slip rectangular rod 33 ensures the stability and safety during the lifting process.

[0073] The synchronous sleeve plate 34 fixedly installed on the anti-slip rectangular rod 33 not only extends above the longitudinal spline cylinder 28 and the mold 60, but also is slidably connected to the L-shaped assembly frame 6 through the rectangular slide opening 35. This design enables the L-shaped assembly frame 6 to move synchronously with the lifting of the synchronous sleeve plate 34, thereby realizing precise adjustment of the height of the vibrating mechanism and ensuring the requirements during the lateral adjustment of the oil cylinder 4.

[0074] Furthermore, the transverse spline cylinder 37 on the second shaft seat 36 and the transverse spline shaft 39 on the top of the L-shaped assembly frame 6 achieve power transmission through the meshing of the bevel gear 1 40. At the same time, the longitudinal transmission shaft 41 and the transverse spline cylinder 37 also achieve power conversion and transmission through the meshing of the bevel gear 2 42.

[0075] Specifically, during use, the output main shaft 8 drives the bevel gear 1 40 to rotate, causing the transverse spline shaft 39 and the transverse spline cylinder 37 to rotate synchronously, and then drives the longitudinal transfer shaft 41, the longitudinal spline shaft 43, and the longitudinal spline cylinder 28 to rotate through the bevel gear 2 42, and finally drives the rotating shaft 20, the rotating disk 21 and the mold 60 to rotate, realizing synchronous driving of stirring and rotation, better vibration effect, and more energy saving.

[0076] The retractability of the transverse spline shaft 39 and the transverse spline cylinder 37, the retractability of the synchronous sleeve 34 and the L-shaped assembly frame 6, can meet the position changes of the lifting plate 3 and the vibrating mechanism when adjusting the transverse position;

[0077] The retractability of the longitudinal spline cylinder 28 and the longitudinal spline shaft 43 can meet the needs of the vibration mechanism when it is raised and lowered, ensuring smooth transmission of power.

[0078] In another embodiment of the present invention, a power assembly port 44 is provided on the longitudinal section of the L-shaped bracket plate 2, and a rotating shaft 45 is rotatably installed in the power assembly port 44. A connecting seat 46 is fixedly sleeved on the rotating shaft 45. The connecting seat 46 is located on one side of the mold 60 and is detachably installed with a connecting screw 47 in a threaded manner. The connecting screw 47 is located at one end of the mold 60 and is fixedly installed with an elastic knocking rod 48 for knocking the mold 60 to vibrate. A rotating shaft 2 49 is rotatably installed in the power assembly port 44, and a support plate 50 is fixedly installed on the longitudinal section of the L-shaped bracket plate 2. A central axis 51 is rotatably installed on the support plate 50. The central shaft 51 and the longitudinal spline cylinder 28 are both fixedly provided with a bevel gear three 52, and the two bevel gear threes 52 are meshed with each other. The central shaft 51 and the rotating shaft 2 49 are both fixedly provided with a bevel gear four 53, and the two bevel gear fours 53 are meshed with each other. A pressure plate 54 is fixedly installed on the rotating shaft 1 45, and the pressure plate 54 is staggered with the connecting seat 46. A cam 55 is fixedly provided on the rotating shaft 2 49, and the rotation of the cam 55 can press the pressure plate 54 to rotate the rotating shaft 1 45. A patch plate 56 is fixedly installed on the connecting seat 46, and a return spring 57 is fixedly installed on the top of the patch plate 56 and the top inner wall of the power assembly port 44.

[0079] In this embodiment, a power assembly port 44 and a knocking mechanism are added to the longitudinal section of the L-shaped support plate 2. A rotating shaft 45 rotatably installed in the power assembly port 44, a connecting seat 46, a connecting lead screw 47, and an elastic knocking rod 48 on it together form a knocking assembly, which is used to knock and vibrate the mold 60 while rotating and vibrating, so as to enhance the density and uniformity of the concrete. The connecting lead screw 47 and the elastic knocking rod 48 are detachably installed on one side of the mold 60 by means of threaded connection, and the selected length of the elastic knocking rod 48 can be replaced according to the size of the mold 60.

[0080] In addition, this embodiment also cleverly uses a gear transmission system to realize the automatic drive of the knocking assembly. The rotating shaft 49 is connected to the middle shaft 51 through a bevel gear 53, and the middle shaft 51 is connected to the longitudinal spline cylinder 28 through a bevel gear 52. Therefore, when the longitudinal spline cylinder 28 (i.e., the power source of the rotating shaft 20) rotates, it can drive the middle shaft 51, the rotating shaft 49, and the cam 55 to rotate synchronously. The rotation of the cam 55 periodically presses the pressure plate 54 to rotate the rotating shaft 45. This rotation compresses the return spring 57 and stores energy. When the convex part of the cam 55 rotates past, the return spring 57 releases energy, pushes the connecting seat 46 to quickly reset, and drives the elastic knocking rod 48 to knock the mold 60.

[0081] The introduction of the knocking assembly in this embodiment enables the device to add knocking vibration on the basis of rotating vibration. This composite vibration method can more effectively remove air bubbles and voids in the concrete, and improve the density and uniformity of the concrete.

[0082] The drive of the knocking assembly completely depends on the power source of the rotating shaft 20, and realizes automatic drive through the gear transmission system, without the need for an additional power source, which simplifies the device structure and reduces the manufacturing cost, and can also be replaced according to the size of the mold 60.

[0083] The connecting lead screw 47 is connected to the connecting seat 46 by means of threads, and the distance and knocking force between the knocking assembly and the mold 60 can be adjusted according to needs, improving the adaptability and flexibility of the device.

[0084] All components are cleverly installed on the longitudinal section of the L-shaped support plate 2, making the device structure compact, occupying a small area, and being convenient for installation and maintenance.

[0085] In another embodiment of the present invention, an electric control box 58 is fixedly installed on the hoisting plate 3, and a dragging guide seat 59 is detachably installed on one side of the base 1. The dragging guide seat 59 has a slope, and its vertex is consistent with the top plane of the rotating disk 21.

[0086] In this embodiment, an electric control box 58 is added to the hoisting plate 3. This design makes the control system of the entire device more centralized and convenient. The electric control box 58 not only provides power supply for the device, but also integrates various control components and switches, enabling the operator to conveniently control functions such as the start, stop, speed regulation, and vibration mode of the device. In addition, the electric control box 58 also has safety functions such as overload protection and short-circuit protection, ensuring the safety and stability of the device during operation.

[0087] At the same time, a dragging guide seat 59 is detachably installed on one side of the base 1. The dragging guide seat 59 has a ramp design, and its apex is flush with the top plane of the rotating disk 21. This design enables the test block to be conveniently slid out from the rotating disk 21 through the dragging guide seat 59 after the test block is made, avoiding the cumbersome and inconvenient manual handling. The ramp design of the dragging guide seat 59 also ensures the smoothness and safety of the test block during the sliding-out process, preventing the test block from being damaged due to collision or jolting.

[0088] In summary, compared with the related technology, the device realizes flexible adjustment of the vibration position through the cooperation of the oil cylinder 4 and the hoisting plate 3, solving the problem of uneven vibration of traditional equipment; secondly, the liftable design of the L-shaped assembly frame 6 enables the vibration mechanism to adapt to different height vibration requirements, improving the versatility and flexibility of the device; finally, the efficient operation of the vibration mechanism ensures the full vibration of the concrete and improves the quality of the test block. In summary, the present invention not only simplifies the vibration steps in the production process of concrete test blocks, but also significantly improves the production efficiency and quality of the test blocks.
