Description

Technical Field

[0001] This invention relates to the field of block grooving technology, and in particular to a grooving device for building concrete blocks. Background Technology

[0002] Concrete blocks are a type of precast block material widely used in construction engineering. They are mainly used to construct walls, foundations, and other structures. With the development of construction engineering, in some application scenarios, such as when it is necessary to enhance structural strength, improve seismic resistance, or increase the embedding depth of reinforced concrete, it is often necessary to groove the blocks. Grooving refers to opening slots inside the blocks to facilitate the embedding of reinforcing bars, reinforcement bars, or other strengthening materials, thereby achieving the purpose of improving the overall performance and stability of the structure.

[0003] For example, Chinese patent CN118514216B proposes a grooving device for aerated concrete blocks. This grooving device fixes the grooving components inside a protective box and guides the aerated concrete blocks using guide rails, eliminating the need for manual grooving and thus increasing grooving efficiency. However, the debris generated during the grooving process cannot be cleaned up in time. During the discharge of the concrete blocks, the debris remaining on the concrete blocks easily falls onto the movement path of the concrete blocks, causing the equipment to jam and affecting the discharge of the concrete blocks. Therefore, we propose a grooving device for building concrete blocks. Summary of the Invention

[0004] The purpose of this invention is to provide a grooving device for building concrete blocks, which facilitates the cleaning of residual material adhering to the concrete blocks to ensure smooth discharge of the concrete blocks.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a grooving device for building concrete blocks, comprising two support frames and an upper guide assembly and a lower guide assembly installed between the two support frames.

[0006] Mounting cover, installed on top of the support frame.

[0007] The slag discharge gap is formed by the distance between the upper guide component and the lower guide component.

[0008] The connecting shell is installed on the opposite sides of the two support frames.

[0009] The slotted assembly is rotatably connected between two connecting shells and passes through the support frame.

[0010] The collection box is installed at the bottom of the support frame and is connected to the slag discharge gap.

[0011] The slag removal assembly is rotatably connected between two support frames. Both the front and rear sides of the slag removal assembly extend into the connecting shell. The slag removal assembly and the grooving assembly are connected by a transmission belt.

[0012] The pressure assembly is located inside the connecting housing and moves up and down within the mounting cover.

[0013] The transmission assembly is installed inside the connecting housing and engages with the slotted assembly.

[0014] The push component is installed inside the connecting housing and meshes with the transmission component. Its upper surface contacts the pressing component and drives the pressing component to move up and down.

[0015] By adopting the above technical solution, during the grooving process of concrete blocks, after the blocks enter through the inlet of the mounting cover, they move directionally along the upper guide component to the grooving component for precise grooving. During grooving, the rotational power of the grooving component synchronously drives the slag removal component through the transmission belt. When the block passes through the slag discharge gap, the slag removal component automatically removes the debris in the groove. The debris falls directly into the collection box for centralized treatment through the slag discharge gap, effectively avoiding secondary pollution and preventing equipment jamming. Finally, the cleaned blocks are smoothly discharged from the outlet of the mounting cover through the lower guide component. The entire process requires no manual intervention, which not only ensures the grooving quality but also significantly improves efficiency.

[0016] During the grooving process, the grooving component synchronously drives the slag removal component to rotate through a linkage design, removing the debris generated during processing. At the same time, the transmission component transmits power to the pushing component, converting it into periodic rotational motion. This, in turn, controls the pressing component to make vertical reciprocating motion within the connecting shell. When the pressing component moves downward, it applies vertical pressure to the top of the concrete block, ensuring that the workpiece does not shift during the grooving process and improving the grooving accuracy. When the pressing component moves upward, it releases the fixation. After the block is pushed a certain distance by the upper and lower guide components, the pressing component presses down again, realizing the coordinated operation of intermittent fixation and continuous grooving.

[0017] The periodic pressing and releasing of the pressing component balances the positioning accuracy and conveying efficiency of concrete blocks, avoiding processing interruptions caused by traditional single-time fixing. The transmission component and transmission belt integrate power distribution functions, synchronously coordinating grooving, slag removal and pressing actions, reducing the need for additional power sources, resulting in lower energy consumption and resource conservation.

[0018] A further configuration of the present invention is as follows: the upper guide assembly includes an upper guide plate installed between two support frames, a plurality of upper guide wheels rotatably connected to the upper guide plate and distributed at equal distances, a cylinder installed at the bottom of the upper guide plate, a horizontal plate connected to the output end of the cylinder, and a friction block installed on the horizontal plate and penetrating the upper guide plate, wherein the friction block is provided in a plurality of manner and is located between two adjacent upper guide wheels.

[0019] By adopting the above technical solution, during the conveying of concrete blocks on the upper guide plate, the rolling support of the upper guide wheel significantly reduces frictional resistance and ensures the smooth movement of the blocks. When the blocks enter the processing area of ​​the grooving component, the cylinder drives the friction block on the horizontal plate to rise to the same level as the upper guide wheel through intermittent retraction, forming a dynamic limit on the blocks. This design achieves precise adjustment of the block conveying speed, ensuring the synchronization and processing accuracy of the grooving process.

[0020] The lifting and lowering motion of the friction block is strictly matched with the working cycle of the grooving component to avoid groove deviation caused by speed fluctuations. The cylinder adopts an adjustable stroke design, which can adjust the pressure and position of the friction block according to different block specifications, further adapting to the flexibility requirements of the production line.

[0021] The upper guide wheel is responsible for unpowered rolling guidance under normal conditions, while the friction block intervenes during the slotting stage to achieve speed buffering through the friction of the contact surface. The combination of the two ensures efficiency and avoids mechanical impact.

[0022] A further embodiment of the present invention is that the lower guide assembly includes a lower guide plate installed between two support frames and a plurality of equally spaced lower guide wheels rotatably connected to the lower guide plate.

[0023] By adopting the above technical solution, the cleaned concrete blocks after grooving are smoothly discharged along the lower guide wheel on the lower guide plate.

[0024] A further configuration of the present invention is as follows: the grooving assembly includes a rotating shaft rotatably connected between two connecting shells, a blade mounted outside the rotating shaft, a transmission wheel and a bevel gear, and a grooving motor mounted on one of the connecting shells. The blade is located between two support frames, and a sawing groove is provided on the upper guide plate for the blade to pass through. The transmission wheel and the bevel gear are located inside the connecting shell.

[0025] By adopting the above technical solution, the grooving motor starts and drives the blade on the rotating shaft to rotate. The blade passes through the upper guide plate to groove the concrete block.

[0026] A further configuration of the present invention is as follows: the slag removal assembly includes a connecting shaft rotatably connected between two support frames, a brush wheel and a rotating wheel installed outside the connecting shaft, the brush wheel having bristles installed on its exterior, the front and rear sides of the connecting shaft extending into the connecting housing, the rotating wheel being located inside the connecting housing and being connected to the transmission wheel via a transmission belt, and the brush wheel being located in the slag discharge gap and corresponding to the position of the blade.

[0027] By adopting the above technical solution, when the grooving motor starts and drives the blades on the rotating shaft to rotate, the transmission wheel also rotates with the rotating shaft. The transmission wheel drives the rotating wheel to rotate through the transmission belt, which in turn causes the brush wheel to drive the brush bristles to rotate, cleaning the debris remaining in the groove of the concrete block. The debris falls directly into the collection box through the slag discharge gap for centralized treatment, effectively avoiding secondary pollution and equipment jamming, and ensuring that the concrete block can be smoothly discharged after grooving. The number of blades can be adjusted according to the actual situation, and the position of the sawing groove and the brush wheel corresponds one-to-one with the position of the blades.

[0028] A further embodiment of the present invention is that the pressing assembly includes an anti-detachment ring installed inside the connecting shell, a connecting rod that slides up and down inside the connecting shell through the anti-detachment ring, a top rod that connects the two connecting rods and passes through the inside of the mounting cover, a pressing plate installed at the bottom of the top rod, and a contact wheel that is rotatably connected to the connecting rod and located inside the connecting shell, wherein a stop block is installed at the bottom of the connecting rod.

[0029] A further configuration of the present invention is as follows: the transmission assembly includes a side plate installed inside the connecting housing, a support shaft rotatably connected to the side plate, and bevel gear two and bevel gear three installed outside the support shaft, wherein bevel gear two meshes with bevel gear one.

[0030] A further configuration of the present invention is as follows: the pushing assembly includes a base plate installed in the connecting housing, a vertical shaft rotatably connected to the base plate, and a bevel gear four and a lifting platform installed on the vertical shaft. The bevel gear four meshes with the bevel gear three, and the upper surface of the lifting platform is an inclined surface that is in contact with the contact wheel.

[0031] By adopting the above technical solution, when the grooving motor starts and drives the blade on the rotating shaft to rotate, the first bevel gear rotates synchronously. The first bevel gear meshes with the second bevel gear, which in turn drives the third bevel gear on the support shaft to rotate. The third bevel gear meshes with the fourth bevel gear, which in turn drives the lifting platform to rotate on the base plate. When the lifting platform rotates, it uses the inclined surface of its upper surface to push the connecting rod to move up and down in the connecting shell, which in turn drives the pressure plate to move up and down. When the pressure plate moves down, it applies vertical pressure to the top of the concrete block to ensure that the workpiece does not move during the grooving process and improves the grooving accuracy. When the pressure plate moves up, it releases the fixation. After the block is pushed a certain distance by the upper guide component and the lower guide component, the pressure plate presses down again, realizing the coordinated operation of intermittent fixing and continuous grooving.

[0032] A further feature of the present invention is that when the lower side of the lifting platform is in contact with the contact wheel, and the connecting rod drives the pressure plate on the top rod to move downward, the output end of the cylinder retracts, causing the friction block to move upward.

[0033] By adopting the above technical solution, the concrete block can be clamped from both the top and bottom during grooving, further causing the concrete block to shift and improving the grooving accuracy.

[0034] A further feature of the present invention is that the upper surface of the support frame is an inclined surface, and an inclined feeding plate is installed on the right side of the lower guide plate.

[0035] By adopting the above technical solution, it is easy to roll the concrete blocks under normal conditions and to properly discharge the cleaned concrete blocks.

[0036] The beneficial effects of this invention are:

[0037] 1. During the grooving process of concrete blocks, after the blocks enter through the inlet of the installation cover, they move directionally along the upper guide component to the grooving component for precise grooving. During grooving, the rotational power of the grooving component drives the slag removal component to operate synchronously through the transmission belt. When the block passes through the slag discharge gap, the slag removal component automatically removes the debris in the groove. The debris falls directly into the collection box for centralized treatment through the slag discharge gap, effectively avoiding secondary pollution. Finally, the cleaned blocks are smoothly discharged from the outlet of the installation cover through the lower guide component. The entire process requires no manual intervention, which not only ensures the grooving quality but also significantly improves efficiency.

[0038] 2. During the grooving process, the grooving component synchronously drives the slag removal component to rotate through a linkage design, removing the debris generated during processing. At the same time, the transmission component transmits power to the pushing component, converting it into periodic rotational motion. This, in turn, controls the pressing component to make vertical reciprocating motion within the connecting shell. When the pressing component moves downward, it applies vertical pressure to the top of the concrete block, ensuring that the workpiece does not shift during the grooving process and improving the grooving accuracy. When the pressing component moves upward, it releases the fixation. After the block is pushed a certain distance by the upper and lower guide components, the pressing component presses down again, realizing the coordinated operation of intermittent fixation and continuous grooving.

[0039] 3. The periodic pressing and releasing of the pressing component balances the positioning accuracy and conveying efficiency of concrete blocks, avoiding processing interruptions caused by traditional single-time fixing. The transmission component and transmission belt integrate power distribution functions, synchronously coordinating grooving, slag removal and pressing actions, reducing the need for additional power sources, resulting in lower energy consumption and resource conservation.

Detailed Implementation

[0048] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] Please see Figure 1-6 The present invention provides a grooving device for building concrete blocks, comprising two support frames 1 and an upper guide assembly 2 and a lower guide assembly 3 installed between the two support frames 1.

[0050] Mounting cover 4 is installed on top of support frame 1.

[0051] The slag discharge gap 5 is formed by the distance between the upper guide component 2 and the lower guide component 3.

[0052] Connecting shell 6 is installed on the opposite sides of the two support frames 1.

[0053] The slotted assembly 7 is rotatably connected between the two connecting shells 6 and passes through the support frame 1.

[0054] The collection box 8 is installed at the bottom of the support frame 1 and is connected to the slag discharge gap 5.

[0055] The slag removal component 9 is rotatably connected between two support frames 1. Both the front and rear sides of the slag removal component 9 extend into the connecting shell 6. The slag removal component 6 and the slotting component 7 are connected by a transmission belt 10.

[0056] The pressing assembly 11 is located inside the connecting shell 6 and moves up and down within the mounting cover 4.

[0057] The transmission assembly 12 is installed inside the connecting housing 6 and engages with the slotted assembly 7.

[0058] The push component 13 is installed inside the connecting shell 6 and meshes with the transmission component 12. Its upper surface contacts the pressing component 11 and drives the pressing component 11 to move up and down.

[0059] During the grooving process of concrete blocks, after the blocks enter through the entrance of the mounting cover 4, they move directionally along the upper guide component 2 to the grooving component 7 for precise grooving. During grooving, the rotational power of the grooving component 7 drives the slag removal component 9 to operate synchronously through the transmission belt 10. When the blocks pass through the slag discharge gap 5, the slag removal component 9 automatically removes the debris in the groove. The debris falls directly into the collection box 8 for centralized treatment through the slag discharge gap 5, effectively avoiding secondary pollution and preventing equipment jamming. Finally, the cleaned blocks are smoothly discharged from the outlet of the mounting cover 4 through the lower guide component 3. No manual intervention is required throughout the process, which not only ensures the grooving quality but also significantly improves efficiency.

[0060] During the grooving process, the grooving component 7 synchronously drives the slag removal component 9 to rotate through a linkage design, removing the slag generated during processing. At the same time, the transmission component 12 transmits power to the pushing component 13, converting it into periodic rotational motion. This, in turn, controls the pressing component 11 to make vertical reciprocating motion within the connecting shell 6. When the pressing component 11 moves downward, it applies vertical pressure to the top of the concrete block, ensuring that the workpiece does not shift during the grooving process and improving the grooving accuracy. When the pressing component 11 moves upward, it releases the fixation. After the block is pushed a certain distance by the upper guide component 2 and the lower guide component 3, the pressing component 13 presses down again, realizing the coordinated operation of intermittent fixation and continuous grooving.

[0061] The periodic pressing and releasing of the pressing component 13 balances the positioning accuracy and conveying efficiency of concrete blocks, avoiding the processing interruption caused by traditional single fixing. The transmission component 12 and the transmission belt 10 integrate the power distribution function, synchronously coordinating the grooving, slag removal and pressing actions, reducing the need for additional power sources, resulting in lower energy consumption and resource conservation.

[0062] The upper guide assembly 2 includes an upper guide plate 21 installed between two support frames 1, multiple upper guide wheels 22 rotatably connected to the upper guide plate 21 and distributed at equal distances, a cylinder 23 installed at the bottom of the upper guide plate 21, a horizontal plate 24 connected to the output end of the cylinder 23, and friction blocks 25 installed on the horizontal plate 24 and passing through the upper guide plate 21. Multiple friction blocks 25 are provided and located between two adjacent upper guide wheels 22. During the conveying of concrete blocks on the upper guide plate 21, the rolling support of the upper guide wheels 22 significantly reduces frictional resistance and ensures the smooth movement of the blocks. When the blocks enter the processing area of ​​the grooving assembly 7, the cylinder 23 drives the friction blocks 25 on the horizontal plate 24 to rise to the same level as the upper guide wheels 22 through intermittent retraction action, forming a dynamic limit on the blocks. This design realizes the precise adjustment of the block conveying speed and ensures the synchronization and processing accuracy of the grooving process.

[0063] The lifting and lowering action of the friction block 25 is strictly matched with the working cycle of the grooving component 7 to avoid groove deviation caused by speed fluctuations. The cylinder 23 adopts an adjustable stroke design, which can adjust the pressure and position of the friction block 25 according to different block specifications, further adapting to the flexibility requirements of the production line.

[0064] The upper guide wheel 22 is responsible for unpowered rolling guidance under normal conditions, while the friction block 25 intervenes during the slotting stage to achieve speed buffering through the friction of the contact surface. The combination of the two ensures efficiency and avoids mechanical impact.

[0065] The lower guide assembly 3 includes a lower guide plate 31 installed between two support frames 1 and a plurality of equally spaced lower guide wheels 32 rotatably connected to the lower guide plate 21. The cleaned concrete blocks after grooving are smoothly discharged along the lower guide wheels 32 on the lower guide plate 31.

[0066] The grooving assembly 7 includes a rotating shaft 71 rotatably connected between two connecting shells 6, a blade 72 mounted outside the rotating shaft 71, a transmission wheel 73 and a bevel gear 74, and a grooving motor 75 mounted on one of the connecting shells 6. The blade 72 is located between two support frames 1, and a sawing groove 14 is provided on the upper guide plate 21 for the blade 72 to pass through. The transmission wheel 73 and the bevel gear 74 are located inside the connecting shell 6. When the grooving motor 75 is started, it drives the blade 72 on the rotating shaft 71 to rotate, and the blade 72 passes through the upper guide plate 21 to groove the concrete block.

[0067] The slag removal assembly 9 includes a connecting shaft 91 rotatably connected between two support frames 1, a brush wheel 92 and a rotating wheel 93 installed outside the connecting shaft 91. The brush wheel 92 is equipped with bristles 94. The front and rear sides of the connecting shaft 91 extend into the connecting housing 6. The rotating wheel 93 is located inside the connecting housing 6 and is connected to the transmission wheel 73 via a transmission belt 10. The brush wheel 92 is located at the slag discharge gap 5 and corresponds to the position of the blade 72. When the grooving motor 75 starts and drives the blade 72 on the rotating shaft 71 to rotate, the transmission wheel 73 also rotates with the rotating shaft 71. The transmission wheel 73 drives the rotating wheel 93 to rotate via the transmission belt 10, which in turn causes the brush wheel 92 to drive the bristles 94 to rotate, cleaning the debris remaining in the groove of the concrete block. The debris falls directly into the collection box 8 through the slag discharge gap 5 for centralized treatment, effectively avoiding secondary pollution and equipment jamming, and ensuring that the concrete block can be smoothly discharged after grooving. The number of blades 72 can be adjusted according to the actual situation. The position of the sawing groove 14 and the brush wheel 73 corresponds one-to-one with the position of the blade 72.

[0068] The pressing assembly 11 includes an anti-detachment ring 111 installed inside the connecting shell 6, a connecting rod 112 that passes through the anti-detachment ring 111 and slides up and down inside the connecting shell 6, a top rod 113 that connects the two connecting rods 112 and passes through the mounting cover 4, a pressing plate 114 installed at the bottom of the top rod 113, and a contact wheel 115 that is rotatably connected to the connecting rod 112 and located inside the connecting shell 6. A stop is installed at the bottom of the connecting rod 112. The transmission assembly 12 includes a side plate 121 installed inside the connecting shell 6 and a rotating... The support shaft 122 is connected to the side plate 121, and bevel gear 123 and bevel gear 124 are installed outside the support shaft 122. Bevel gear 123 meshes with bevel gear 74. The pushing assembly 13 includes a base plate 131 installed in the connecting housing 6, a vertical shaft 132 rotatably connected to the base plate 131, and bevel gear 133 and a lifting platform 134 installed on the vertical shaft 132. Bevel gear 133 meshes with bevel gear 124. The upper surface of the lifting platform 134 is inclined and fits against the contact wheel 115.

[0069] When the grooving motor 75 starts and drives the blade 72 on the rotating shaft 71 to rotate, the first bevel gear 74 rotates synchronously. The first bevel gear 74 meshes with the second bevel gear 123, which in turn drives the third bevel gear 124 on the support shaft 122 to rotate. The third bevel gear 124 meshes with the fourth bevel gear 133, which in turn drives the lifting platform 134 to rotate on the base plate 131. When the lifting platform 134 rotates, it uses the inclined surface of its upper surface to push the connecting rod 112 to move up and down in the connecting shell 6, which in turn drives the pressure plate 114 to move up and down. When the pressure plate 114 moves down, it applies vertical pressure to the top of the concrete block to ensure that the workpiece does not move during the grooving process and improves the grooving accuracy. When the pressure plate 114 moves up, it releases the fixation. After the block is pushed a certain distance by the upper guide component 2 and the lower guide component 3, the pressure plate 114 presses down again to achieve the coordinated operation of intermittent fixing and continuous grooving.

[0070] When the lower side of the lifting platform 134 is in contact with the contact wheel 115, and the connecting rod 112 drives the pressure plate 114 on the top rod 113 to move down, the output end of the cylinder 23 retracts and drives the friction block 25 to move up. During grooving, the concrete block can be clamped from both the top and bottom sides, further causing the concrete block to shift and improving the grooving accuracy.

[0071] The upper surface of the support frame is inclined, and the right side of the lower guide plate 31 is equipped with an inclined discharge plate 15, which facilitates the rolling of concrete blocks under normal conditions and the normal discharge of cleaned concrete blocks.

[0072] Furthermore, the width of the slag discharge gap 5 is controlled within 1 / 5 of the length of the concrete block (e.g., if the block length is 500mm, the gap is <100mm). This not only meets the slag discharge requirements but also prevents the block from getting stuck or shifting when the upper guide component 2 and the lower guide component 3 move. The slag discharge gap 5 mainly serves the installation space requirements of the slag removal component 9 and provides a directional discharge channel for the cutting residue. Its width design must ensure that the residue (particle diameter <5mm³) can pass through efficiently without reducing the strength of the block support surface due to excessive width.
