[0002] The concrete distribution device is mainly a concrete distribution machine. The concrete distribution machine is a key equipment in concrete construction, which is specially used for transporting and distributing the mixed concrete to a designated pouring position.

[0016] The beneficial effects of the present application are as follows: 1. The concrete distributing device provided by the present application can change the final discharging point of the concrete by rotating the rectangular frame, the guide frame and the extension frame through the actual required guide position by using the rotating column, and then connecting the screw on the rectangular frame with the threaded hole at the bottom of the boss, and then fixing the rectangular frame, the guide frame and the extension frame, so that the subsequent concrete flowing out through the hanging pipe will not change the position of the guide frame and the extension frame due to external force. Meanwhile, the extension frame can be slid according to the actual requirement, so that the extension frame slides out to the required length, and the concrete is precisely guided. The designed structure realizes the precise guidance of the material of the concrete distributing machine, and changes the discharging point of the concrete according to the actual situation. Thus, when the space is narrow, the structure designed according to the present application can quickly and efficiently guide the concrete to the required distributing point, thereby reducing the difficulty of concrete distribution, and improving the precision of concrete distribution.

[0017] 2. The concrete distributing device disclosed by the application utilizes an electric push rod to move a plurality of vibrating rods away from the storage slot through a connecting plate and a plurality of ball heads, so that one end of the vibrating rod is inserted into the concrete at the bottom of the extension frame to perform the vibrating work. The mechanism is designed to realize the vibrating of the concrete at the material outlet of the extension frame, thereby solving the problem that the concrete at the material outlet of the extension frame is in a "dynamic accumulation" state, new concrete is continuously covered on the discharged concrete, the vibrating rod is buried by the new concrete as soon as it is inserted, and accurate vibrating cannot be performed on the "just discharged concrete". At the same time, the concrete at the material outlet of the extension frame continuously flows out, and cement slurry splashes, so if a worker is at the place to vibrate, there is a great safety hazard. When the output end of the electric push rod moves with the connecting plate and the vibrating rod, the first and second extension members move with the connecting plate, thereby protecting the output rod of the electric push rod. After the output rod of the electric push rod is extended out of the storage slot, the cement slurry splashes on the output rod of the electric push rod, causing problems in subsequent resetting and damage. The arc-shaped guide plate and the flexible material guide column are installed to guide the vibrating rod that is vertically lowered during resetting, so that the vibrating rod is rotated and lifted after contacting the arc-shaped guide plate, thereby facilitating the vibrating rod to enter the storage slot and avoiding the vibrating rod being stuck in the guide frame.

[0018] 3. The concrete distributing device disclosed by the application utilizes the gas in the two protection members to be squeezed into the two placement slots, and moves the sealing plate and the scraper in the placement slot, so that the scraper assists in cleaning the residual concrete impurities on the vibrating rod. After the vibrating rod is used, the scraper also cleans the concrete on the vibrating rod, thereby reducing the concrete adhering to the vibrating rod. The scraper is designed to be arc-shaped to facilitate the sealing plate to reset into the placement slot, effectively preventing the scraper from being stuck at the port of the placement slot during resetting. When the rectangular frame is removed from the rotating column, the auxiliary plate is also separated from the groove, so that the protection member in the groove resets, thereby sucking the gas in the placement slot back. At this time, the sealing plate and the scraper made of lightweight material also reset into the placement slot.

[0019] 4. The concrete distributing device disclosed by the application sprays the liquid in the first multi-stage extension member to the vibrating rod through the second liquid guide pipe after the guide frame and the extension frame are used. Since the first multi-stage extension member is continuously contracted, the liquid in the first multi-stage extension member is also continuously sprayed to the surface of the vibrating rod, thereby cooperating with the scraper to scrape off the residual concrete on the vibrating rod. The design effectively reduces the residual concrete adhering to the surface of the vibrating rod, changes the original cylindrical structure of the vibrating rod, reduces the effective vibrating radius when vibrating, reduces the contact area between the vibrating rod and the concrete, and hinders the vibration energy transmission, thereby making it difficult for the concrete to be liquefied and vented.

[0020] The liquid in the second multi-stage telescopic part enters the liquid spraying opening through the second liquid guide pipe, and is sprayed into the material guide frame and the extension frame through the liquid spraying opening, thereby assisting in reducing the solidification of concrete in the material guide frame and the extension frame, facilitating the subsequent workers to remove the residual concrete, and ensuring the efficient flow guiding operation of the extension frame and the material guide frame.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figures 1 to 10 As shown, a concrete distribution device according to an embodiment of the present invention includes a concrete distribution boom 1, mounted with a hanging pipe 2 for discharging materials; a material guide mechanism 10 is provided on the hanging pipe 2. The material guide mechanism 10 includes a boss 11 fixedly connected to the hanging pipe 2, a rotating column 12 rotatably connected to the bottom of the boss 11, a rectangular frame 13 provided at the bottom of the rotating column 12, a through slot 14 extending through the top of the rectangular frame 13, a bolt 15 threadedly connected to the inner surface of the rectangular frame 13, and a plurality of threaded holes 16 arranged in a ring on the side of the boss 11 near the rotating column 12. An inclined material guide frame 17 is fixedly mounted on one side of the rectangular frame 13, an extension frame 18 slidably connected to the interior of the material guide frame 17, and the extension frame 18 and the material guide frame 17 are fixed by an insert rod 19.

[0026] Specifically, an auxiliary mechanism 20 is disposed within the rotating column 12. The auxiliary mechanism 20 comprises two symmetrically arranged slots 21 within the rotating column 12. An auxiliary plate 22 is slidably connected to the slots 21 via springs. Both the slots 21 and the auxiliary plate 22 are L-shaped, with the bottom of the auxiliary plate 22 protruding from the rotating column 12. Two symmetrically arranged grooves 23 are defined within the rectangular frame 13 and communicate with the through-slot 14. Protective members 30 made of an elastic material are fixedly mounted within each groove 23.

[0027] During operation, when using the concrete placing boom 1 for concrete distribution, the rectangular frame 13 and the boss 11 are first assembled, so that the rotating column 12 is inserted into the through-slot 14 of the rectangular frame 13. The two auxiliary plates 22 are then slid toward each other to continue moving upward without hindering the upward movement of the rectangular frame 13. As the rectangular frame 13 continues to move upward, the two auxiliary plates 22 are loosened. When the grooves 23 in the rectangular frame 13 and the auxiliary plates 22 are aligned, the two auxiliary plates 22 return to their original position under the action of two springs and squeeze the push-open guard 30 into the grooves 23, securing the rectangular frame 13 to the rotating column 12. At this point, the rotating column 12 drives the rectangular frame 13, the material guide frame 17, and the extension frame 18 to rotate according to the actual location of the concrete being directed, thereby changing the final discharge point of the concrete.

[0028] After the above operation is completed, the bolt 15 on the rectangular frame 13 is screwed to connect with the threaded hole 16 at the bottom of the boss 11, and then the rectangular frame 13, the material guiding frame 17 and the extension frame 18 are fixed, so that after the subsequent concrete flows out through the hanging pipe 2, the position of the material guiding frame 17 and the extension frame 18 will not be changed due to external force. At the same time, the extension frame 18 can be slid according to the actual needs, so that the extension frame 18 slides out the required length, and the concrete is precisely guided.

[0029] The above-mentioned design structure realizes precise guidance of the material of the concrete distributing machine 1, and changes the concrete discharging point according to the actual situation. Therefore, when the space is narrow, the structure designed in the application can quickly and efficiently guide the concrete to the required distribution point, thereby reducing the difficulty of concrete distribution and improving the precision of concrete distribution.

[0030] The material guiding frame 17 is provided with a vibrating mechanism 40. The vibrating mechanism 40 comprises a receiving groove 41 formed in the material guiding frame 17. An electric push rod 42 is fixedly installed in the receiving groove 41. A plurality of vibrating rods 43 are connected to the output end of the electric push rod 42. A connecting plate 44 is fixedly installed at the output end of the electric push rod 42. The end of the connecting plate 44 away from the electric push rod 42 is connected to the plurality of vibrating rods 43 through a plurality of ball heads 45.

[0031] Specifically, the electric push rod 42 is provided with a protection mechanism 50. The protection mechanism 50 comprises two first multi-stage extension members 51 and second multi-stage extension members 52 which are symmetrically and fixedly installed on the electric push rod 42. The ends of the first multi-stage extension members 51 and the second multi-stage extension members 52 away from the electric push rod 42 are fixedly connected to the connecting plate 44. The first multi-stage extension members 51 and the second multi-stage extension members 52 cooperatively form a circular ring and cover the output end of the electric push rod 42. The first multi-stage extension members 51 and the second multi-stage extension members 52 are both composed of a plurality of hollow and semicircular plates which are slidingly connected.

[0032] Specifically, one side of the material guiding frame 17 is provided with a guide mechanism 60. The guide mechanism 60 comprises a guide plate 61 which is fixedly connected to the material guiding frame 17 and is arc-shaped. A plurality of guide columns 62 made of flexible material are rotatably connected to one side of the guide plate 61.

[0033] When the guide frame 17 and the extension frame 18 complete the preliminary installation work, the concrete flows out through the hanging pipe 2, and the electric push rod 42 in the receiving groove 41 is started, the electric push rod 42 moves away from the receiving groove 41 through the connecting plate 44 and the plurality of ball heads 45 with the plurality of vibrating rods 43. As the vibrating rod 43 is separated from the receiving groove 41, it is no longer limited and will rotate and droop under the influence of gravity, and as the electric push rod 42 continues to move, one end of the vibrating rod 43 will be inserted into the concrete at the bottom of the extension frame 18 for vibrating work. Through the designed mechanism, the concrete at the material port of the extension frame 18 is vibrated, thereby solving the problem that the concrete at the material port of the extension frame 18 is in a “dynamic accumulation” state, and the new concrete continuously covers the discharged concrete, so that the vibrating rod 43 is buried by the new concrete as soon as it is inserted, and cannot accurately vibrate the “just discharged concrete”. At the same time, the concrete at the material port of the extension frame 18 continuously flows out, and cement slurry splashes, if the artificial is in the place for vibrating, there is a great safety hazard.

[0034] When the output end of the electric push rod 42 moves with the connecting plate 44 and the vibrating rod 43, the first and second telescopic members move with the connecting plate 44, thereby protecting the output rod of the electric push rod 42. After the output rod of the electric push rod 42 extends out of the receiving groove 41, the cement slurry splashes on the output rod of the electric push rod 42, causing problems in subsequent resetting and damage.

[0035] At the same time, the arc-shaped guide plate 61 and the flexible material guide column 62 are installed, which can guide the vibrating rod 43 that is vertically lowered during resetting, so that the vibrating rod 43 is rotated and lifted after contacting the arc-shaped guide plate 61, thereby facilitating the entry into the receiving groove 41 and avoiding the situation that the vibrating rod 43 is stuck in the guide frame 17.

[0036] The guide frame 17 is provided with a cleaning mechanism 70, the cleaning mechanism 70 includes two placing grooves 71 opened in the guide frame 17, the two placing grooves 71 are symmetrically distributed with the center axis of the receiving groove 41, the inside of the placing groove 71 is sealingly and slidably connected with a sealing plate 72, one end of the sealing plate 72 is rotatably connected with a scraper 73 through a torsional spring. The protection piece 30 is a hollow elastic block, and the protection piece 30 is connected with the placing groove 71 through the air guide pipe 74.

[0037] When the rectangular frame 13 and the rotating column 12 are installed, and the auxiliary plate 22 is inserted into the groove 23 and extrudes the protective piece 30, the protective piece 30 in the two grooves 23 is extruded, and the gas in the two protective pieces 30 is extruded into the two placing grooves 71, and the sealing plate 72 and the scraping plate 73 in the placing groove 71 are pushed to move. The sealing plate 72 and the scraping plate 73 move away from the placing groove 71, and the torsional spring rotates the scraping plate 73 to rotate, and with the movement of the subsequent vibrating rod 43, the scraping plate 73 assists in cleaning the residual concrete impurities on the vibrating rod. After the vibrating rod 43 is used, the scraping plate 73 also cleans the concrete on the vibrating rod 43, thereby reducing the concrete adhered to the vibrating rod 43.

[0038] It should be noted that the scraping plate 73 is designed to be arc-shaped to facilitate the sealing plate 72 to reset into the placing groove 71, effectively preventing the situation that the scraping plate 73 is stuck at the port of the placing groove 71 during resetting. When the rectangular frame 13 is removed from the rotating column 12, the auxiliary plate 22 is also separated from the groove 23, so that the protective piece 30 in the groove 23 resets, thereby sucking the gas in the placing groove 71 back. At this time, the sealing plate 72 and the scraping plate 73 made of lightweight material also reset into the placing groove 71, facilitating the next use.

[0039] The storage groove 41 is provided with a liquid spraying mechanism 80, which includes a liquid storage tank 81 fixedly installed in the storage groove 41. One side of the liquid storage tank 81 is fixedly installed with a liquid inlet pipe 82 communicating with the inside and having a one-way valve. One side of the liquid storage tank 81 is fixedly installed with a first liquid outlet pipe 83 communicating with the inside and having a one-way valve. One end of the first liquid outlet pipe 83 away from the liquid storage tank 81 is communicated with the inside of the first multi-stage telescopic piece 51. The first multi-stage telescopic piece 51 is composed of a plurality of hollow and semicircular plate sealing sliding connections, and the hollow plates are communicated with each other. One side of the first multi-stage telescopic piece 51 is fixedly installed with a first liquid guide pipe 84 communicating with the inside and having a one-way valve. One end of the first liquid guide pipe 84 away from the first multi-stage telescopic piece 51 is close to the vibrating rod 43.

[0040] Specifically, one side of the liquid storage tank 81 is fixedly installed with a second liquid outlet pipe 85 with a one-way valve. One end of the second liquid outlet pipe 85 away from the liquid storage tank 81 is communicated with the inside of the second multi-stage telescopic piece 52. The second multi-stage telescopic piece 52 is composed of a plurality of hollow and semicircular plate sealing sliding connections, and the hollow plates are communicated with each other. One side of the second multi-stage telescopic piece 52 is fixedly installed with a second liquid guide pipe 86 communicating with the inside and having a one-way valve. One side of the guide frame 17 is provided with a plurality of inclined liquid spraying ports 87. One end of the second liquid guide pipe 86 away from the second multi-stage telescopic piece 52 is communicated with the liquid spraying port 87.

[0041] When the first multi-stage telescopic member 51 and the second multi-stage telescopic member 52 are stretched following the connecting plate 44, the first telescopic member will suck the liquid (a weak acid compound solution, or other suitable liquid according to actual situation) in the liquid storage tank 81 through the first liquid outlet pipe 83, and the second telescopic member will suck the liquid in the liquid storage tank 81 through the second liquid outlet pipe 85.

[0042] When the material guide frame 17 and the extension frame 18 are used up, the electric push rod 42 will reset the vibrating rod 43 through the connecting plate 44, at this time, the first multi-stage telescopic member 51 and the second multi-stage telescopic member 52 will also follow the contraction reset. The liquid in the first multi-stage telescopic member 51 is sprayed to the vibrating rod 43 through the second liquid guide pipe 86, because the first multi-stage telescopic member 51 is continuously contracted, so the liquid in it will also continuously spray to the surface of the vibrating rod 43, and then cooperate with the scraper 73 to scrape off the residual concrete on the vibrating rod 43. Through the above design, the residual concrete (especially after hardening) attached to the surface of the vibrating rod 43 is effectively reduced, the original cylindrical structure of the vibrating rod 43 is changed, the effective vibration radius is reduced when vibrating, the contact area between the vibrating rod 43 and the concrete is reduced, and the vibration energy transmission is blocked, making it difficult for the concrete to fully liquefy and exhaust.

[0043] The liquid in the second multi-stage telescopic member 52 will enter the liquid outlet 87 through the second liquid guide pipe 86, and be sprayed into the material guide frame 17 and the extension frame 18 through the liquid outlet 87, so as to assist in reducing the concrete solidified in the material guide frame 17 and the extension frame 18, facilitating the subsequent workers to remove the residual concrete, and ensuring the efficient flow guiding operation of the extension frame 18 and the material guide frame 17.

[0044] When the liquid in the liquid storage tank 81 is used up, it can be supplemented through the liquid inlet pipe 82.

[0045] Working principle: when using the concrete distributor 1 to distribute, first install the rectangular frame 13 with the boss 11, so that the rotating column 12 is inserted into the through slot 14 of the rectangular frame 13, and the two auxiliary plates 22 are moved in the direction of approaching each other, thereby not hindering the upward movement of the rectangular frame 13. As the rectangular frame 13 continues to move upward, the two auxiliary plates 22 are loosened, and when the recess 23 in the rectangular frame 13 is in the same straight line as the auxiliary plate 22, the two auxiliary plates 22 will reset under the action of the two springs and press the protective piece 30 into the recess 23, so that the rectangular frame 13 and the rotating column 12 are fixed. At this time, according to the actual position of the material to be guided, the rotating column 12 drives the rectangular frame 13, the guide frame 17 and the extension frame 18 to rotate, thereby changing the final discharge point of the concrete. After the above operation is completed, the bolt 15 on the rectangular frame 13 is screwed with the threaded hole 16 at the bottom of the boss 11, thereby fixing the rectangular frame 13, the guide frame 17 and the extension frame 18, so that after the subsequent concrete flows out through the hanging pipe 2, the position of the guide frame 17 and the extension frame 18 will not be changed due to external force.

[0046] When the guide frame 17 and the extension frame 18 complete the preliminary installation work, after the concrete flows out through the hanging pipe 2, the electric push rod 42 in the storage slot 41 is started, and the electric push rod 42 moves away from the storage slot 41 with the connecting plate 44 and a plurality of ball heads 45. As the vibrating rod 43 is separated from the storage slot 41, it is no longer restricted, and at the same time, it will rotate and droop under the influence of gravity, and as the electric push rod 42 continues to move, one end of the vibrating rod 43 will be inserted into the concrete at the bottom of the extension frame 18 for vibrating work. When the output end of the electric push rod 42 moves with the connecting plate 44 and the vibrating rod 43, the first and second extension pieces will move together with the connecting plate 44. The installed arc-shaped guide plate 61 and the flexible material guide column 62 play a role in guiding the vibrating rod 43 that is reset and droops, so that the vibrating rod 43 is rotated and lifted after contacting the arc-shaped guide plate 61, thereby facilitating the entry into the storage slot 41 and avoiding the situation of being stuck in the guide frame 17.

[0047] When the rectangular frame 13 and the rotating column 12 are installed, and the auxiliary plate 22 is inserted into the recess 23 and presses the protective piece 30, the protective piece 30 in the two recesses 23 is pressed, and the gas in the two protective pieces 30 is pressed into the two placement slots 71, and the sealing plate 72 and the scraper 73 in the placement slot 71 are moved. The sealing plate 72 and the scraper 73 move away from the placement slot 71, and the scraper 73 connected by the torsional spring rotates, and as the subsequent vibrating rod 43 moves, the scraper 73 assists in cleaning the concrete impurities remaining on the vibrating rod. And after the vibrating rod 43 is used, the scraper 73 also cleans the concrete on the vibrating rod 43, thereby reducing the concrete sticking to the vibrating rod 43.

[0048] When the first multi-stage telescopic member 51 and the second multi-stage telescopic member 52 stretch along with the connecting plate 44, the first telescopic member will suck the liquid in the liquid storage tank 81 through the first liquid outlet pipe 83, and the second telescopic member will suck the liquid in the liquid storage tank 81 through the second liquid outlet pipe 85. When the material guide frame 17 and the extension frame 18 are used up, the electric push rod 42 will reset the vibrating rod 43 through the connecting plate 44, at this time, the first multi-stage telescopic member 51 and the second multi-stage telescopic member 52 will also reset along with the contraction. The liquid in the first multi-stage telescopic member 51 is sprayed to the vibrating rod 43 through the second liquid guide pipe 86, because the first multi-stage telescopic member 51 is continuously contracted, so the liquid in it will also continuously spray to the surface of the vibrating rod 43, and then cooperate with the scraper 73 to scrape off the residual concrete on the vibrating rod 43. The liquid in the second multi-stage telescopic member 52 will enter the liquid outlet 87 through the second liquid guide pipe 86, and be sprayed into the material guide frame 17 and the extension frame 18 through the liquid outlet 87. When the liquid in the liquid storage tank 81 is used up, it can be supplemented through the liquid inlet pipe 82.
