Description

Technical Field

[0001] This invention belongs to the field of concrete feeding technology, and in particular relates to a buffer feeding device for preventing segregation of concrete. Background Technology

[0002] With the increase in the height difference of concrete conveying, conveying methods such as bucket or conveyor belt conveying cannot meet the construction requirements due to slow conveying speed and long construction period. Concrete conveying by chute has the advantages of fast speed and continuous pouring, and it is one of the main concrete conveying methods in the current construction process.

[0003] Maintaining the homogeneity of all components in concrete is key to its successful application. During the vertical transport of concrete, the aggregates and slurry in the concrete are subjected to different stresses and have different speeds. When the transport height exceeds a certain value, the aggregates will separate from the slurry, causing segregation. In order to control the speed of concrete exiting the chute and reduce segregation, a buffer needs to be installed at the chute outlet.

[0004] A high-drop cast-in-place concrete anti-segregation feeding diversion buffer, disclosed in CN118881372A, includes a hollow box, an inlet conduit and an outlet conduit located at the top and bottom of the hollow box, a support plate welded inside the hollow box, multiple vertical springs welded on the support plate, and a buffer plate welded to the top of all the springs, with the buffer plate located directly below the outlet of the inlet conduit and the top surface of the buffer plate aligned with the outlet of the inlet conduit.

[0005] The aforementioned buffer only achieves the buffering effect during the concrete impact process through a buffer plate connected to a spring inside the hollow box. This single buffer structure has limited buffering capacity for high-drop concrete and does not achieve the multiple buffering effect when transporting high-drop concrete. Summary of the Invention

[0006] The purpose of this invention is to provide a buffer feeding device for concrete to prevent segregation. Through the specific structural design of the pipe body assembly, the rotating buffer assembly, the translational buffer assembly, the linkage assembly, the wall cleaning assembly, the material feeding buffer section, and the buffer feeding mechanism, the invention solves the problem that the existing single buffer structure has limited buffering capacity for high-drop concrete and fails to achieve multiple buffering effects when transporting high-drop concrete.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a buffer feeding device for preventing segregation of concrete, comprising a first buffer feeding mechanism and a second buffer feeding mechanism that are concentrically connected; the first buffer feeding mechanism includes a first pipe assembly, the first pipe assembly includes a first feeding pipe, the top of the first feeding pipe is eccentrically connected to an inlet pipe, the inner side of the first feeding pipe is rotatably provided with a rotating buffer assembly, and the inlet pipe is configured to guide concrete to impact the rotating buffer assembly.

[0008] The second buffer feeding mechanism includes a second feeding pipe connected to the bottom of the first feeding pipe and configured to introduce concrete that has been buffered by the rotating buffer assembly; and a translational buffer assembly slidably disposed inside the second feeding pipe via a guide rod and configured to achieve concrete flow guidance and buffering through horizontal reciprocating motion.

[0009] The invention is further configured such that two fixing ears are symmetrically arranged on the circumference of the feeding tube, and fixing seats connected to the feeding tube are arranged in a circumferential array below the fixing ears. A synchronous wheel and a bevel gear are connected to the circumference of the feeding tube near the bottom via a rotating shaft. The rotating buffer assembly includes a support tube, and positioning seats with positioning grooves are symmetrically fixed on the inner wall of the feeding tube. The support tube is located in the positioning groove between the two positioning seats, and several impact buffer plates are arranged in a circumferential array on the circumferential side of the support tube.

[0011] The present invention is further configured such that the buffer feeding mechanism one further includes a wall cleaning component, the wall cleaning component includes a rotating ring attached to the bottom of the feeding pipe one, a sealed ring attached to the inner wall of the rotating ring is fixed on the inner wall of the feeding pipe one, a wall cleaning component is attached between the inner walls of the feeding pipe one and the feeding pipe two, the wall cleaning component is arranged in a circumferential array on the sealed ring, and a bevel gear ring one is concentrically fixed on the top of the rotating ring, the bevel gear ring one meshing with the bevel gear one above it.

[0012] The present invention is further configured such that a support cover 1 coaxial with the top of the feed tube 2 is fixed thereon, the top of the support cover 1 is provided with an annular sealing groove, the outer diameter of the rotating ring is the same as the inner diameter of the support cover 1, a sealing ring that rotates and cooperates with the annular sealing groove is fixed at the bottom of the rotating ring, and the support cover 1 and the fixed seat are connected by fasteners.

[0013] The present invention is further configured such that the translation buffer assembly includes a scraper frame slidably sleeved between the guide rods, an arched buffer plate with an arched structure fixed at the top of the scraper frame, a rectangular guide ring fixed at the center of the top of the scraper frame, a support plate fixed at the bottom of the second feeding pipe, a feeding hopper connected to the second feeding pipe fixed at the bottom of the support plate, and a discharge pipe connected to the bottom of the feeding hopper.

[0014] The present invention is further configured such that a drive shaft is rotatably provided on the second feeding tube, which passes through the inner side of the scraping frame. One end of the drive shaft is connected to a motor on the second feeding tube, and a synchronous wheel three is fixed on the other end of the drive shaft. A drive plate located inside the scraping frame is fixed on the drive shaft, and an eccentric push rod that cooperates with the rectangular guide ring is fixed on one side of the drive plate.

[0015] The present invention is further configured such that a second support cover is installed at the bottom of the support disk and sleeved on the outside of the hopper, and a second bevel gear ring coaxial with the support disk is rotatably provided on the inner side of the second support cover. The second bevel gear ring is a ring gear structure with teeth on both sides. The second bevel gear and the fourth synchronous wheel are connected to the second support cover by a rotating shaft. The third synchronous wheel and the fourth synchronous wheel are connected by a synchronous belt. The second bevel gear meshes with one side of the second bevel gear ring.

[0016] The present invention is further configured such that the circumferential array of the hopper is provided with a plurality of material feeding buffers, each material feeding buffer including a material feeding buffer component and a bevel gear three connected by a rotating shaft, the material feeding buffer component being fitted to the inner wall of the hopper, the bevel gear three meshing with the other side of the bevel gear ring two, and two gripping parts being symmetrically installed on the top of the support plate.

[0017] The present invention has the following beneficial effects: 1. The present invention sets up a first buffer feeding mechanism and a second buffer feeding mechanism that are concentrically connected. A rotating buffer assembly is rotatably set inside the first feeding pipe. An inlet pipe is connected to the top of the first feeding pipe at an eccentric position. The inlet pipe is configured to guide concrete to impact the rotating buffer assembly. The translation buffer assembly is configured to guide and buffer the concrete through horizontal reciprocating motion. Through the combined use of the rotating buffer assembly and the translation buffer assembly, a double buffer structure is formed in the process of conveying high-drop concrete, which can greatly improve the buffer and anti-segregation effect of high-drop concrete.

[0018] 2. In this invention, the concrete conveyed to the feed pipe through the chute directly impacts the impact buffer plate of the rotating buffer assembly. The impact buffer plate rotates under the action of the impact kinetic energy of the concrete, and the impact buffer plate converts the impact kinetic energy of the concrete into the circumferential motion kinetic energy of each wall cleaning component. This not only achieves buffering and anti-segregation of concrete conveyed with high drop, but also converts the impact kinetic energy into the rotational kinetic energy of the wall cleaning component, so as to clean the concrete splashed onto the pipe wall by the rotating impact buffer plate.

[0019] 3. In the process of controlling the horizontal reciprocating motion of the arc-shaped buffer plate, the invention drives the bevel gear two to rotate under the combined action of synchronous pulley three, synchronous pulley four, and synchronous belt. The rotating bevel gear two drives the bevel gear ring two to rotate, and under the action of the bevel gear ring two, it drives the synchronous rotation of each bevel gear three, thereby realizing the synchronous rotation of each material-pushing buffer component on the inner wall of the hopper. The concrete, after being guided and buffered by the arc-shaped buffer plate, falls onto the inner wall of the hopper. The concrete falling onto the inner wall of the hopper is scraped off into the discharge pipe under the rotation of the material-pushing buffer component. The rotation of the material-pushing buffer component further buffers the falling concrete and cleans the concrete adhering to the inner wall of the hopper, thus avoiding the problem of material waste caused by the undischarged concrete adhering to the inner wall of the hopper.

Detailed Implementation

[0032] 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.

[0033] Example 1, please refer to Figures 1-10 This invention relates to a buffer feeding device for concrete to prevent segregation, comprising a first buffer feeding mechanism 1 and a second buffer feeding mechanism 2, which are concentrically connected. The first buffer feeding mechanism 1 includes a pipe assembly 3, which includes a feeding pipe 4. An inlet pipe 5 is connected to the top of the feeding pipe 4 at an eccentric position. A rotating buffer assembly 6 is rotatably mounted inside the feeding pipe 4. The inlet pipe 5 is configured to guide concrete to impact the rotating buffer assembly 6. The second buffer feeding mechanism 2 includes a second feeding pipe 7 and a translational buffer assembly 8. The second buffer assembly 7 is connected to the bottom of the feeding pipe 4 and is configured to guide the concrete buffered by the rotating buffer assembly 6. The translational buffer assembly 8 is slidably mounted inside the second feeding pipe 7 via a guide rod 9 and is configured to guide and buffer the concrete through horizontal reciprocating motion. The combined use of the rotating buffer assembly 6 and the translational buffer assembly 8 forms a double buffer structure during the high-drop concrete conveying process, thereby greatly improving the buffering and anti-segregation effect of high-drop concrete.

[0034] In this embodiment of the invention, such as Figure 3 and Figure 4 As shown, two fixed ears 10 are symmetrically arranged on the side of the feed pipe 4. The top of the feed pipe 5 is installed at the outlet of the chute through a flange, and the fixed ears 10 are used to install the connecting rope. The connecting rope is used to control the movement of the entire buffer feed device. The fixed seats 11 connected to the feed pipe 4 are arranged in a circumferential array below the fixed ears 10. The side of the feed pipe 4 is close to the bottom and is connected to the synchronous wheel 12 and the bevel gear 13 through a rotating shaft.

[0035] In this embodiment of the invention, such as Figure 5 As shown, the rotary buffer assembly 6 includes a support tube 14. The inner wall of the feed tube 4 is symmetrically fixed with positioning seats having positioning grooves. The positioning groove on each positioning seat is located at its bottom. The support tube 14 is positioned within the positioning groove between two positioning seats to limit the horizontal movement of the rotary buffer assembly 6. Several impact buffer plates 15 are arranged in a circumferential array on the circumferential side of the support tube 14, such as... Figure 2 As shown, the concrete conveyed to the feed pipe 5 by the chute directly impacts the impact buffer plate 15 of the rotating buffer assembly 6. When the impact buffer plate 15 is impacted by the concrete, it rotates to reduce the speed of the concrete falling and achieve the effect of buffering the concrete and preventing segregation.

[0036] Example 2, based on Example 1, such as Figure 3 and Figure 6 As shown, the buffer feeding mechanism 1 also includes a linkage component 16, which includes a linkage rod 17 that is installed through the feeding pipe 4, and a support pipe 14 that is sleeved on the linkage rod 17.

[0037] The linkage rod 17 has a limiting protrusion fixed on its circumferential side, which mates with the limiting groove in the support tube 14. One end of the linkage rod 17 is fitted with a locking tube 18 by fasteners. (It should be noted that after the rotation buffer assembly 6 is installed inside the feed tube 4 via the linkage assembly 16, the end of the linkage rod 17 relative to the locking tube 18 fits into a circular groove on one side of the outer wall of the feed tube 4, while the locking tube 18 fits into a circular groove on the other side of the outer wall of the feed tube 4, thus ensuring that the linkage rod 17 can rotate freely.) A second synchronous pulley 19 is fixedly installed on the locking tube 18. The first synchronous pulley 12 and the second synchronous pulley 19 are connected by a synchronous belt 20. Matching teeth are provided on the inner surface of the synchronous belt 20 and on the inner sides of the first synchronous pulley 12 and the second synchronous pulley 19 to ensure the synchronous transmission of the first synchronous pulley 12, the second synchronous pulley 19 and the synchronous belt 20.

[0038] In this embodiment of the invention, such as Figure 3 and Figure 4As shown, the buffer feeding mechanism 1 also includes a wall cleaning component 21. The wall cleaning component 21 includes a rotating ring 22 attached to the bottom of the feeding pipe 4. A sealing ring 23 attached to the inner wall of the rotating ring 22 is fixed to the inner wall of the feeding pipe 4. The sealing ring 23 ensures that the concrete in the feeding pipe 4 can smoothly enter the feeding pipe 7 and ensures the sealing of the connection between the feeding pipe 4 and the feeding pipe 7. A wall cleaning component 24 is attached between the inner walls of the feeding pipe 4 and the feeding pipe 7. The wall cleaning component 24 is arranged in a circumferential array on the sealing ring 23. A bevel gear ring 25 is concentrically fixed to the top of the rotating ring 22. The bevel gear ring 25 meshes with the bevel gear 13 above it.

[0039] The concrete conveyed into the feed pipe 5 by the chute directly impacts the impact buffer plate 15 of the rotating buffer assembly 6. The impact buffer plate 15 rotates under the action of the impact kinetic energy of the concrete (that is, when the flowing concrete drives the impact buffer plate 15 to rotate, the rotating impact buffer plate 15 can achieve the purpose of energy dissipation, thereby reducing the wear of the flowing concrete on the impact buffer plate 15, and the impact buffer plate 15 is made of wear-resistant high-strength material commonly used in the prior art). The rotating support pipe 14 drives the linkage rod 17 to rotate, and under the action of the second synchronous pulley 19, the first synchronous pulley 12 and the synchronous belt 20, the first bevel gear is driven. 13 rotates, and then through the transmission action of bevel gear 13 and bevel gear ring 25, the various wall cleaning components 24 scrape on the inner walls of discharge pipe 1 4 and discharge pipe 2 7. In this way, the concrete splashed onto the inner walls of discharge pipe 1 4 and discharge pipe 2 7 during the buffering process can be cleaned. This application converts the impact kinetic energy of concrete into the circumferential motion kinetic energy of each wall cleaning component 24 through the impact buffer plate 15. This not only achieves buffering and anti-segregation of high-drop conveyed concrete, but also converts the impact kinetic energy into the rotational kinetic energy of the wall cleaning component 24, so as to achieve the cleaning of concrete splashed onto the pipe wall by the rotation of the impact buffer plate 15.

[0040] Example 3, based on Examples 1 and 2, as follows: Figure 2 and Figure 7 As shown, a support cover 26 coaxial with the top of the feeding tube 2 7 is fixed. The top of the support cover 26 is provided with an annular sealing groove 27. The outer diameter of the rotating ring 22 is the same as the inner diameter of the support cover 26. A sealing ring that rotates and engages with the annular sealing groove 27 is fixed at the bottom of the rotating ring 22. The support cover 26 and the fixed seat 11 are connected by fasteners. After the assembly of the buffer feeding mechanism 1 and the buffer feeding mechanism 2 2 is completed, the rotating ring 22 is attached to the bottom of the support cover 26. At this time, the sealing ring at the bottom of the rotating ring 22 is engaged in the annular sealing groove 27.

[0041] In this embodiment of the invention, such as Figure 9 and Figure 10As shown, the translational buffer assembly 8 includes a scraper 28 slidably sleeved between guide rods 9 (the contact surface between the scraper 28 and the guide rods 9 can be made of high-strength rubber rings or other high-strength sliding structures to improve the scraping effect on the surface of the guide rods 9; this is existing technology and will not be described in detail here). During the reciprocating motion of the scraper 28 along the guide rods 9, the cement adhering to the guide rods 9 can be scraped off by the scraper 28, achieving the purpose of cleaning the surface of the guide rods 9. An arched buffer plate 29 with an arched structure is fixed to the top of the scraper 28. Through the structural design of the arched buffer plate 29, the concrete falling onto the top of the arched buffer plate 29 can be buffered and guided (i.e., by moving towards...). The intermittent blocking effect of the arc-shaped buffer plate 29 in the reciprocating motion of the concrete buffers the concrete. A rectangular guide ring is fixed at the top center of the scraper frame 28. During the concrete conveying process, the scraper frame 28 protects the rectangular guide ring, drive plate, and eccentric push rod, preventing concrete from adhering to them. A support plate 30 is fixed at the bottom of the discharge pipe 27. A discharge hopper 31 connected to the discharge pipe 27 is fixed at the bottom of the support plate 30. A discharge pipe 32 is connected to the bottom of the discharge hopper 31. The concrete, after being guided and buffered by the arc-shaped buffer plate 29, falls into the discharge hopper 31 and is then discharged through the discharge pipe 32 to be transported to the construction area.

[0042] In this embodiment of the invention, such as Figure 10 As shown, a drive shaft 33 is rotatably mounted on the second feeding pipe 7, passing through the inner side of the scraper 28 (the bottom of the wall cleaning component 24 is higher than the drive shaft 33 to avoid motion interference). One end of the drive shaft 33 is connected to a motor 34 on the second feeding pipe 7 (a power supply for the motor 34 and a controller for controlling the motor 34 are installed on the outer wall of the second feeding pipe 7; this is prior art and will not be described in detail). A synchronous pulley 35 is fixed to the other end of the drive shaft 33. A drive plate located inside the scraper 28 is fixed on the drive shaft 33. An eccentric push rod (made of wear-resistant and high-strength material) is fixed on one side of the drive plate and fits into a rectangular guide ring. (The materials used in the prior art are not described in detail here). During the concrete conveying process, the drive shaft 33 is rotated by the motor 34. Under the action of the drive shaft 33, the drive plate is rotated. The eccentric push rod that moves synchronously with the drive plate pushes the rectangular guide ring to reciprocate, thereby realizing the horizontal reciprocating motion of the arc-shaped buffer plate 29 along the guide rod 9. During the movement of the arc-shaped buffer plate 29, the synchronous wheel 35 is rotated. (It should be noted that during the reciprocating motion of the arc-shaped buffer plate 29 and the scraper 28 at the bottom, the position of the drive shaft 33 will not interfere with the reciprocating motion of the scraper 28 at all.)

[0043] Example 4, based on Examples 1 to 3, as follows: Figure 10As shown, a support cover 36 is installed at the bottom of the support plate 30 and sleeved on the outside of the hopper 31. A bevel gear ring 37 coaxial with the support plate 30 is rotatably provided on the inner side of the support cover 36. The bevel gear ring 37 is a ring gear structure with teeth on both sides (this is prior art and will not be described in detail). A bevel gear 38 and a synchronous pulley 39 are connected to the support cover 36 through a rotating shaft. The synchronous pulley 35 and the synchronous pulley 39 are connected by a synchronous belt 20 (the inner surface of the synchronous belt 20 and the inner sides of the synchronous pulleys 35 and 39 are provided with matching teeth to ensure the synchronous transmission of the synchronous pulleys 35, 39 and the synchronous belt 20). The bevel gear 38 meshes with one side of the bevel gear ring 37.

[0044] Furthermore, the circumferential array around the hopper 31 is provided with several material-pushing buffer sections 40. Each material-pushing buffer section 40 includes a material-pushing buffer element 41 and a bevel gear 42 connected by a rotating shaft. The material-pushing buffer element 41 is fitted against the inner wall of the hopper 31, and the bevel gear 42 meshes with the other side of the bevel gear ring 37. Two gripping parts 43 are symmetrically installed on the top of the support plate 30. During the horizontal reciprocating motion of the arc-shaped buffer plate 29 controlled by the motor 34, the bevel gear 38 is driven to rotate under the combined action of the synchronous pulley 35, the synchronous pulley 49, and the synchronous belt 20. The rotating bevel gear 38 drives the bevel gear ring 37 to rotate, and under the action of the bevel gear ring 37, the synchronous rotation of each bevel gear 42 is achieved, thereby realizing the synchronous rotation of the material-pushing buffer inside the hopper 31. The synchronous rotation of each material feeding buffer 41 on the wall causes the concrete, after being guided and buffered by the arc-shaped buffer plate 29, to fall onto the inner wall of the discharge hopper 31. The concrete falling onto the inner wall of the discharge hopper 31 is scraped off into the discharge pipe 32 by the rotation of the material feeding buffer 41. The rotation of the material feeding buffer 41 further buffers the falling concrete (the rotation direction of each material feeding buffer 41 is opposite to the concrete discharge direction, thereby reducing the falling speed of the concrete to achieve buffering). At the same time, it can clean the concrete adhering to the inner wall of the discharge hopper 31 to avoid the waste of raw materials caused by the concrete adhering to the inner wall of the discharge hopper 31 not being discharged (after the concrete conveying operation is completed, the entire buffer discharge device is cleaned in time).
