Description

Technical Field

[0001] The present invention relates to the technical field of slope protection brick preparation, and specifically to a preparation method and a preparation device for environmentally friendly river slope protection bricks. Background Technique

[0002] As an important water conservancy project material, environmentally friendly river slope protection bricks have been widely used in river regulation and ecological restoration due to their good water permeability, anti-scouring property, and ecological and environmental protection characteristics. In the process of preparing environmentally friendly river slope protection bricks, compression molding is one of the key links, which directly relates to the molding quality, overall strength, and subsequent use performance of the slope protection bricks;

[0003] At present, most of the preparation devices for environmentally friendly river slope protection bricks adopt a continuous pressing method, that is, the upper mold and the lower mold continuously maintain a closed mold state, and raw materials are continuously injected into the mold and pressed to achieve continuous production of slope protection bricks. Although this continuous pressing method improves production efficiency to a certain extent, there are also many deficiencies:

[0004] Unstable molding quality: During the continuous pressing process, the distribution and compaction of raw materials in the mold are often not uniform enough, which easily leads to defects such as air bubbles, voids, and cracks inside the slope protection bricks, affecting their density and overall strength;

[0005] Poor adaptability to raw materials: For some raw materials that require a long time to be evenly distributed and compacted, the continuous pressing method often cannot ensure that they are fully processed, thus affecting the molding quality and performance of the slope protection bricks;

[0006] Insufficient product uniformity and stability: During the continuous pressing process, due to the uneven distribution and compaction of raw materials, the size and shape of each slope protection brick are likely to be different, affecting the uniformity and stability of the product. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a preparation method and a preparation device for environmentally friendly river slope protection bricks, which solve the technical problems mentioned in the background technique.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: A preparation device for environmentally friendly river slope protection bricks includes a base frame. At the bottom of the inner cavity of the base frame, there is a workbench. On the top of the workbench, there is a lower mold. Outside the lower mold, there is a connection frame. Above the lower mold, there is an upper mold. On the top of the upper mold, there is a moving frame. On both sides of the base frame, there are guide rods, with two guide rods on each side, and the connection frame and the moving frame are slidably installed on the guide rods. On the top of the base frame, there is a control component for driving the moving frame and the upper mold to move downward;

[0009] The control component includes a positioning rod fixedly connected to a U-shaped rod fixedly installed on the base frame. A sliding plate is slidably connected to the positioning rod, and a first damping spring is sleeved on the positioning rod and located at the bottom of the sliding plate. Convex rods are fixedly connected to both ends of the sliding plate, and fixing rods are fixedly connected to both sides of the bottom of the sliding plate. The bottoms of the fixing rods are fixedly connected to the top of the moving frame. A pressing plate is arranged on one side of the U-shaped rod for intermittently pushing the sliding plate, the fixing rods, the moving frame and the upper die downward.

[0010] As a further preference of this technical solution, mounting plates are fixedly installed on both sides of the base frame. Two groups of inclined plates are arranged on the mounting plates. Chute grooves are formed on the surfaces of the inclined plates, and a rectangular plate is slidably connected in the chute grooves. A cross bar is fixedly connected to the side wall of the rectangular plate. The outer walls of two cross bars on the same side are rotatably connected to a V-shaped rod, and a first linkage rod is movably connected to the outer walls of two cross bars on the same side. The two ends of two V-shaped rods on the same side are movably connected to a second linkage rod and a vertical plate, and a row of pressing plates is fixedly connected to one side of the vertical plate.

[0011] As a further preference of this technical solution, a servo motor is fixedly installed on one side of the lower part. The output end of the servo motor is fixedly connected to a rotating rod, and the other end of the rotating rod is rotatably connected to a pushing rod. The other end of the pushing rod is movably connected to the cross bar located below.

[0012] As a further preference of this technical solution, a row of sliding rods is slidably connected to the U-shaped rod. Limit blocks and triangular blocks are respectively fixedly connected to both ends of the sliding rods. The position of the triangular block corresponds to the position of the convex rod, and a second damping spring sleeved on the sliding rod is arranged between the triangular block and the U-shaped rod.

[0013] As a further preference of this technical solution, a second air cylinder is fixedly installed on the U-shaped rod. The output end of the second air cylinder is fixedly connected to a movable rod, and a side rod fixedly installed on the side wall of the triangular block is arranged on one side of the movable rod.

[0014] As a further preference of this technical solution, a vibration motor is arranged at the bottom of the workbench, and first air cylinders fixedly installed on the base frame are arranged on both sides of the connecting frame.

[0015] As a further preference of this technical solution, rack bars are fixedly connected to both sides of the upper die. Positioning shafts fixedly installed on the connecting frame are arranged on both sides of the lower die. A chassis is fixedly connected to the side of the positioning shaft close to the lower die. A plurality of knocking rods for knocking on the outer wall of the lower die are slidably arranged in a circumferential array on the chassis.

[0016] As a further preference of this technical solution, a cylinder is rotatably connected to the outer wall of the positioning shaft. A gear ring meshing with the rack bar is fixedly connected to one side of the cylinder. A reciprocating groove is formed on the outer wall of the cylinder, and a sliding column installed at the end of the knocking rod is slidably connected in the reciprocating groove.

[0017] The present invention also discloses a preparation method of an environmentally friendly river slope protection brick, which specifically includes the following steps:

[0018] Step 1: After putting the raw materials into the lower mold, start the vibration motor, and the vibration motor drives the lower mold and the raw materials inside to vibrate;

[0019] Step 2: Then, start the servo motor to drive the rotating rod to rotate synchronously. The rotating rod drives the push rod to move reciprocally, so that the cross bar realizes reciprocating movement and swinging. At the same time, as the push rod moves, it drives the V-shaped rod to swing reciprocally during the reciprocating movement. This swinging action further drives the vertical plate and the pressing plate to move reciprocally left and right downward. When the pressing plate moves from top to bottom, it pushes the sliding plate to slide downward on the positioning rod. The moving range of the sliding plate is from one triangular block to the position of another triangular block. This design enables the sliding plate, the fixed rod, the moving frame and the upper mold to move downward intermittently, and compress the first damping spring, thereby enabling the upper mold to move toward the lower mold side and perform mold closing and mold opening operations with the lower mold, so as to realize the pressing and forming treatment of the raw materials in the lower mold;

[0020] Step 3: After the pressing and forming of the raw materials in the lower mold is completed, when the upper mold moves upward, it can drive the toothed rod to move upward, so that the toothed rod drives the meshing toothed ring to rotate, and then drives the cylinder to rotate synchronously. The rotating cylinder drives the knocking rod to move horizontally reciprocally on the chassis through the reciprocating groove and the sliding column, so that multiple knocking rods reciprocally knock the outer wall of the lower mold. The vibration generated by the knocking helps the formed slope protection brick to break away from the lower mold.

[0021] Compared with the prior art, the following beneficial effects are achieved:

[0022] Through the coordinated work of components such as the servo motor, rotating rod, push rod, inclined plate, rectangular plate, cross bar, V-shaped rod, second linkage rod and vertical plate, the intermittent pushing of the pressing plate on the upper mold is realized, thus ensuring the intermittent mold closing and mold opening operations of the upper mold and the lower mold. This intermittent pressing method not only improves the forming quality and overall strength of the slope protection brick, but also avoids uneven raw material distribution or internal defects caused by continuous high-strength pressing; the intermittent pressing method reduces the wear degree of the mold, because the mold has a short rest time after each pressing, which helps to reduce the fatigue and damage of the mold caused by long-term continuous work, thereby extending the service life of the mold; the ingenious design of the inclined plate, rectangular plate and sliding groove provides accurate guidance for the movement of the push rod, ensuring the accuracy of its movement trajectory, thus ensuring the stability and reliability of the pressing operation.

[0023] By means of intermittent pressing, it allows the raw materials to have more sufficient time to be evenly distributed and compacted within the mold. This helps to reduce the generation of defects such as bubbles, voids, and cracks, thereby improving the density and overall strength of the slope protection bricks. In addition, intermittent pressing can also ensure that the size and shape of each slope protection brick are more consistent, improving the uniformity and stability of the product. The intermittent pressing method can adapt to raw materials of different types and properties. For some raw materials that require a longer time to be evenly distributed and compacted, intermittent pressing can ensure that they are fully processed, thus producing high-quality slope protection bricks.

[0024] During the process of the upper mold descending, by utilizing the meshing of the rack and the gear ring and the rotation of the cylinder, the knocking rod is driven to reciprocally knock on the outer wall of the lower mold. The generated vibration can effectively promote the flow of the raw materials within the cavity of the lower mold, reducing the generation of defects such as bubbles and voids, thereby significantly improving the quality and yield rate of the slope protection bricks; after the pressing and forming is completed, when the upper mold rises, the knocking rod continues to reciprocally knock on the outer wall of the lower mold. This vibration helps the formed slope protection bricks to be more easily detached from the lower mold, reducing the risk of product damage and further ensuring the integrity and quality of the product.

Specific implementation mode

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Embodiment 1: In combination with Figures 1-8 As shown, the present invention provides a technical solution: a preparation device for an environmentally friendly river slope protection brick, including a base frame 1. A workbench 2 is arranged at the bottom of the inner cavity of the base frame 1. A lower mold 3 is arranged on the top of the workbench 2. A connecting frame 23 is arranged outside the lower mold 3. An upper mold 4 is arranged above the lower mold 3. A moving frame 6 is arranged on the top of the upper mold 4. Guide rods 5 are arranged on both sides of the base frame 1, with two guide rods 5 arranged on each side, and the connecting frame 23 and the moving frame 6 are slidably installed on the guide rods 5. A control component 7 for driving the moving frame 6 and the upper mold 4 to move downward is arranged on the top of the base frame 1;

[0036] The control component 7 includes a U-shaped rod 713 fixedly installed on the base frame 1. A positioning rod 714 is fixedly connected to the U-shaped rod 713. A sliding plate 715 is slidably connected to the positioning rod 714, and a first damping spring 718 located at the bottom of the sliding plate 715 is sleeved on the positioning rod 714. Convex rods 717 are fixedly connected to both ends of the sliding plate 715. Fixed rods 716 are fixedly connected to both sides of the bottom of the sliding plate 715. The bottom of the fixed rods 716 is fixedly connected to the top of the moving frame 6. A pressing plate 79 for pushing the sliding plate 715, the fixed rods 716, the moving frame 6 and the upper mold 4 to move downward intermittently is arranged on one side of the U-shaped rod 713;

[0037] On both sides of the base frame 1, mounting plates 71 are fixedly installed. Two groups of inclined plates 72 are arranged on the mounting plates 71. Sliding grooves are formed on the surfaces of the inclined plates 72, and rectangular plates 73 are slidably connected in the sliding grooves. A cross bar 74 is fixedly connected to the side wall of the rectangular plate 73. The outer walls of two cross bars 74 on the same side are rotatably connected with a V-shaped rod 75, and a first linkage rod 76 is movably connected to the outer walls of two cross bars 74 on the same side. The two ends of two V-shaped rods 75 on the same side are movably connected with a second linkage rod 77 and a vertical plate 78. A row of pressing plates 79 are fixedly connected to one side of the vertical plate 78;

[0038] A servo motor 711 is fixedly installed on the lower side. The output end of the servo motor 711 is fixedly connected with a rotating rod 712. The other end of the rotating rod 712 is rotatably connected with a push rod 710. The other end of the push rod 710 is movably connected with the cross bar 74 located below;

[0039] A row of sliding rods 719 are slidably connected to the U-shaped rod 713. Limit blocks 721 and triangular blocks 720 are respectively fixedly connected to both ends of the sliding rod 719. The position of the triangular block 720 corresponds to the position of the convex rod 717, and a second damping spring 722 sleeved on the sliding rod 719 is arranged between the triangular block 720 and the U-shaped rod 713;

[0040] A second air cylinder 725 is fixedly installed on the U-shaped rod 713. The output end of the second air cylinder 725 is fixedly connected with a movable rod 724. A side rod 723 fixedly installed on the side wall of the triangular block 720 is arranged on one side of the movable rod 724.

[0041] In the embodiment of the present invention, by starting the servo motor 711 to drive the rotating rod 712 to rotate synchronously, the rotating rod 712 drives the push rod 710 to reciprocate. This action is transmitted to the cross bar 74 through the push rod 710, enabling it to reciprocate and swing. At the same time, the ingenious design of the inclined plate 72, the rectangular plate 73 and the sliding groove provides accurate guidance for the movement of the push rod 710, ensuring that its movement trajectory is accurate. As the push rod 710 moves, the second linkage rod 77 and the V-shaped rod 75 also start to play a role. They work together to drive the V-shaped rod 75 to reciprocate and swing during the reciprocating movement. This swinging action further drives the vertical plate 78 and the pressing plate 79 to move reciprocally left and right downward;

[0042] When the pressing plate 79 moves from top to bottom, it pushes the sliding plate 715 to slide downward on the positioning rod 714. The moving range of the sliding plate 715 is from one triangular block 720 to the position of another triangular block 720. This design enables the sliding plate 715, the fixed rod 716, the moving frame 6 and the upper die 4 to move downward intermittently, and compress the first damping spring 718. Furthermore, it makes the upper die 4 move towards the lower die 3, and perform the mold closing and mold opening operations with the lower die 3, so as to realize the pressing and forming process of the raw materials in the lower die 3. The intermittent pressing can ensure that the raw materials have enough time to be evenly distributed and compacted in the lower die 3, avoiding uneven distribution of raw materials or internal defects caused by continuous high-intensity pressing, thereby improving the forming quality and overall strength of the slope protection bricks. And the intermittent pressing can reduce the wear degree of the mold, because the mold has a short rest time after each pressing, which helps to reduce the fatigue and damage of the mold caused by long-term continuous work, thus prolonging the service life of the mold;

[0043] During the downward movement, the convex rods 717 arranged on both sides of the sliding plate 715 play a key role. When the sliding plate 715 moves, the convex rods 717 contact the inclined surface of the triangular block 720 and push it to move. The triangular block 720 slides on the U-shaped rod 713 under the guidance of the sliding rod 719, and compresses the second damping spring 722. When the convex rod 717 slides past the inclined surface of one triangular block 720, the triangular block 720 resets under the elastic force of the second damping spring 722 to prepare for the next push;

[0044] When the pressing and forming of one time is completed, by starting the second cylinder 725 to drive the movable rod 724 to move towards the U-shaped rod 713, the movable rod 724 drives all the side rods 723 to move synchronously. Furthermore, the side rods 723 drive the triangular block 720 and the sliding rod 719 to move synchronously, and compress the second damping spring 722. When the triangular block 720 no longer blocks the convex rod 717, the convex rod 717, the sliding plate 715, the fixed rod 716, the moving frame 6 and the upper die 4 move upward and reset under the elastic force of the first damping spring 718 to prepare for the next pressing and forming.

[0045] Embodiment 2: Combine Figure 2As shown, on the basis of the first embodiment, a vibration motor 21 is carefully designed and installed at the bottom of the workbench 2. In addition, both sides of the connecting frame 23 are ingeniously fixed and installed on the base frame 1, and a first cylinder 22 is equipped. When production operations need to be carried out, first, the raw materials are put into the lower mold 3. Subsequently, the vibration motor 21 is started, and the motor starts to work, driving the lower mold 3 and the raw materials therein to vibrate regularly. This vibration helps the raw materials to be tightly filled in every corner of the lower mold 3, thereby significantly improving the forming effect. After the raw materials are filled by vibration, then the upper mold 4 is used to press and form the raw materials in the lower mold 3. Once the forming process is completed, the first cylinder 22 is activated to drive the connecting frame 23 to move upward, and this action realizes the demolding process. Finally, the slope protection bricks that have been demolded and placed on the workbench 2 are taken out.

[0046] In the embodiment of the present invention, after the raw materials are put into the lower mold 3, the vibration motor 21 is immediately started. The start of the vibration motor 21 causes the lower mold 3 and the raw materials therein to start vibrating. This vibration helps the raw materials to be tightly filled in the lower mold 3, thereby improving the forming effect. After the raw materials are filled by vibration, the upper mold 4 will apply pressure to the raw materials in the lower mold 3 for pressing and forming. Once the forming process is over, the first cylinder 22 is immediately activated to drive the connecting frame 23 to move upward, thereby realizing the demolding process. After demolding is completed, the slope protection bricks can be easily taken out from the workbench 2 to complete the entire production process.

[0047] Embodiment Three: Combining Figure 2 、 Figure 4 、 Figure 5 As shown, on the basis of the second embodiment, rack bars 41 are fixedly connected to both sides of the upper mold 4, while positioning shafts 42 fixedly installed on the connecting frame 23 are provided on both sides of the lower mold 3. A chassis 46 is fixedly connected to the side of the positioning shaft 42 close to the lower mold 3. A plurality of knocking rods 47 for knocking on the outer wall of the lower mold 3 are slidably arranged in a circumferential array on the chassis 46;

[0048] In addition, a cylinder 44 is rotatably connected to the outer wall of the positioning shaft 42. A toothed ring 43 meshing with the rack bar 41 is fixedly connected to one side of the cylinder 44. A reciprocating groove 45 is formed in the outer wall of the cylinder 44, and a sliding column 48 installed at the end of the knocking rod 47 is slidably connected in the reciprocating groove 45;

[0049] In an embodiment of the present invention, when the upper mold 4 moves downward, it can drive the rack 41 to move downward, causing the rack 41 to drive the engaged gear ring 43 to rotate, and further driving the cylinder 44 to rotate synchronously. The rotating cylinder 44 drives the striking rod 47 to reciprocate horizontally on the chassis 46 through the reciprocating groove 45 and the sliding column 48, so that a plurality of striking rods 47 reciprocally strike the outer wall of the lower mold 3. The vibration generated by the striking helps the flow of the raw material in the cavity of the lower mold 3, reduces the generation of defects such as bubbles and voids, and improves the quality and yield of the slope protection bricks.

[0050] After the raw material in the lower mold 3 is pressed and formed, when the upper mold 4 moves upward, it can drive the rack 41 to move upward, causing the rack 41 to drive the engaged gear ring 43 to rotate, and further driving the cylinder 44 to rotate synchronously. The rotating cylinder 44 drives the striking rod 47 to reciprocate horizontally on the chassis 46 through the reciprocating groove 45 and the sliding column 48, so that a plurality of striking rods 47 reciprocally strike the outer wall of the lower mold 3. The vibration generated by the striking helps the formed slope protection bricks to detach from the lower mold 3, further ensuring the integrity and quality of the product.

[0051] The present invention also discloses a preparation method for environmentally friendly river slope protection bricks, which specifically includes the following steps:

[0052] Step 1: After putting the raw material into the lower mold 3, turn on the vibration motor 21, and the vibration motor 21 drives the lower mold 3 and the raw material inside to vibrate.

[0053] Step 2: Then, turn on the servo motor 711 to drive the rotating rod 712 to rotate synchronously. The rotating rod 712 drives the push rod 710 to reciprocate, causing the cross bar 74 to reciprocate and swing. At the same time, as the push rod 710 moves, it drives the V-shaped rod 75 to reciprocate and swing during the reciprocating movement. This swinging action further drives the vertical plate 78 and the pressing plate 79 to reciprocate left and right downward. When the pressing plate 79 moves from top to bottom, it pushes the sliding plate 715 to slide downward on the positioning rod 714. The moving range of the sliding plate 715 is from one triangular block 720 to the position of another triangular block 720. This design enables the sliding plate 715, the fixed rod 716, the moving frame 6 and the upper mold 4 to intermittently move downward and compress the first damping spring 718, so that the upper mold 4 moves toward the lower mold 3 and performs mold closing and mold opening operations with the lower mold 3, thereby realizing the pressing and forming process of the raw material in the lower mold 3.

[0054] Step three, after the raw material in the lower mold 3 is pressed and formed, when the upper mold 4 moves upward, it can drive the gear rod 41 to move upward, so that the gear rod 41 drives the meshing gear ring 43 to rotate, and then drives the cylinder 44 to rotate synchronously, and the rotating cylinder 44 drives the knocking rod 47 located on the chassis 46 to move back and forth horizontally through the reciprocating groove 45 and the sliding column 48, so that multiple knocking rods 47 reciprocate on the outer wall of the lower mold 3, and the vibration generated by the knocking helps the formed slope protection bricks to separate from the lower mold 3.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

On one side of the movable rod (724), there is a side rod (723) fixedly installed on the side wall of the triangular block (720).

6. The preparation device of an environmentally friendly river slope protection brick according to claim 1, characterized in that: A vibration motor (21) is provided at the bottom of the workbench (2), and first cylinders (22) fixedly installed on the base frame (1) are provided on both sides of the connecting frame (23).

7. The preparation device of an environmentally friendly river slope protection brick according to claim 1, characterized in that: Toothed rods (41) are fixedly connected to both sides of the upper mold (4), positioning shafts (42) fixedly installed on the connecting frame (23) are provided on both sides of the lower mold (3), a chassis (46) is fixedly connected to the side of the positioning shaft (42) close to the lower mold (3), and a plurality of knocking rods (47) for knocking on the outer wall of the lower mold (3) are slidably arranged in a circumferential array on the chassis (46).

8. The preparation device of an environmentally friendly river slope protection brick according to claim 1, characterized in that: A cylinder (44) is rotatably connected to the outer wall of the positioning shaft (42), a toothed ring (43) meshing with the toothed rod (41) is fixedly connected to one side of the cylinder (44), a reciprocating groove (45) is formed in the outer wall of the cylinder (44), and a sliding column (48) installed at the end of the knocking rod (47) is slidably connected in the reciprocating groove (45).

9. The preparation method of an environmentally friendly river slope protection brick according to any one of claims 1-8, characterized in that: Specifically, it includes the following steps: Step 1: After putting the raw materials into the lower mold (3), turn on the vibration motor (21), and the vibration motor (21) drives the lower mold (3) and the raw materials inside to vibrate. Step 2: Then, turn on the servo motor (711) to drive the rotating rod (712) to rotate synchronously. The rotating rod (712) drives the push rod (710) to reciprocate, so that the cross bar (74) realizes reciprocating movement and swinging. At the same time, as the push rod (710) moves, it drives the V-shaped rod (75) to reciprocate and swing during the reciprocating movement. This swinging action further drives the vertical plate (78) and the pressing plate (79) to move reciprocally left and right downward. When the pressing plate (79) moves from top to bottom, it pushes the sliding plate (715) to slide downward on the positioning rod (714). The moving range of the sliding plate (715) is from one triangular block (720) to the position of another triangular block (720). This design enables the sliding plate (715), the fixed rod (716), the moving frame (6) and the upper mold (4) to move downward intermittently and compress the first damping spring (718), thereby enabling the upper mold (4) to move toward the lower mold (3) and perform mold closing and mold opening operations with the lower mold (3), so as to realize the pressing and forming process of the raw materials in the lower mold (3). Step 3: After the pressing and forming of the raw materials in the lower mold (3) is completed, when the upper mold (4) moves upward, it can drive the toothed rod (41) to move upward, so that the toothed rod (41) drives the meshing toothed ring (43) to rotate, and then drives the cylinder (44) to rotate synchronously. The rotating cylinder (44) drives the knocking rod (47) to reciprocate horizontally on the chassis (46) through the cooperation of the reciprocating groove (45) and the sliding column (48), so that a plurality of knocking rods (47) reciprocally knock on the outer wall of the lower mold (3). The vibration generated by the knocking helps the formed slope protection bricks to break away from the lower mold (3).
