[0003] In the process of forming shoulder by slip form machine, two to three workers need to follow the slip form machine and observe the surface condition of the formed shoulder in real time. When the surface flatness of the shoulder is not enough or there is a lack of concrete, workers need to make real-time remediation to ensure the forming effect of the shoulder. At present, for the uneven surface of the shoulder, a troweling plate is arranged on the shoulder, and the troweling plate is connected to the tail of the slip form machine by a traction rope to move with the slip form machine, so as to realize the function of troweling the surface of the shoulder. However, it is still impossible to supplement concrete in the place where the concrete is missing on the surface of the shoulder. Usually, workers still rely on hand-held scrapers to attach concrete to the side of the shoulder and then manually supplement and trowel the concrete, which not only has low efficiency, but also affects the overall flatness of the shoulder surface. At the same time, it is difficult to effectively cover the overall area of the shoulder, thereby affecting the forming effect of the shoulder. SUMMARY

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. By using side panels and trowels to move close to the sides and top of the shoulder guard, smoothing and finishing operations on all three sides of the shoulder guard can be achieved, improving the forming effect. When the worker observes that the side of the shoulder guard needs additional concrete, they directly rotate the handle. On the one hand, the pressure in the side filling bin is used to press the concrete onto the side of the shoulder guard; on the other hand, the side moving plate continuously pats the concrete onto the side of the shoulder guard, improving the adhesion of the concrete. Then, the side panels are used for smoothing and finishing, improving the forming effect of the side of the shoulder guard. When the worker observes that the top of the shoulder guard needs additional concrete, they directly rotate the operating handle to allow the concrete in the top filling bin to enter the top V-shaped cavity. Then, the trowel pushes the concrete forward on the top of the shoulder guard, achieving the work of adding concrete to the top of the shoulder guard, smoothing and finishing the surface, improving the forming effect of the side of the shoulder guard.

[0016] 2. By setting a locking plate and cooperating the locking plate with the first plate, when the pressure is too high during the process of the worker manually turning the handle to pressurize the side feeding chamber, the first plate can lock the reciprocating double-cylinder power structure through the rotating plate driving the locking plate, so that the handle cannot be turned, and thus automatically stop the pressurization process of the side feeding chamber. This can avoid the worker's operation causing excessive pressure to affect the shoulder molding and improve the use effect.

[0017] 3. The lateral movable plate can also perform scraping operations on the side of the shoulder guard, which can scrape off excess concrete on the side of the shoulder guard. The scraped concrete is located in the area behind the lateral movable plate. When the lateral movable plate switches to the concrete patting state, the scraped concrete can be used to replenish the concrete on the surface of the shoulder guard, realizing the recycling of concrete and further improving the use effect.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0021] like Figures 1 to 15 As shown, the present invention provides an integrated shoulder pad sliding mold device with automatic face-gathering function, comprising: Hopper 1 is connected to the tail of slipform machine 2 by a traction rope and is used to slide on top of the shoulder. Hopper 1 contains concrete material for replenishing the shoulder. Side cover 3 is fixedly installed on both sides of hopper 1 and is used to slide close to the side of the shoulder guard; Please refer to Figure 6 and Figure 8 As shown, there are lateral arc-shaped cavity 4 and lateral V-shaped cavity 5. Lateral arc-shaped cavity 4 is located on the inner side of lateral cover plate 3 and its inner side is open. Lateral V-shaped cavity 5 is located at the rear end of lateral arc-shaped cavity 4. Lateral cover plate 3 slides close to the side wall of shoulder guard, so that shoulder guard closes the opening of lateral arc-shaped cavity 4 and lateral V-shaped cavity 5. Please refer to Figure 6 , Figure 8 and Figure 9As shown, the lateral feeding channel 6 is located on the rear side of the lateral arc-shaped cavity 4. Concrete can enter the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5 through the lateral feeding channel 6. During the forward displacement of the lateral cover plate 3, the concrete located in the lateral V-shaped cavity 5 will adhere to the shoulder side wall. During the process of the lateral V-shaped cavity 5 passing the concrete adhering to the shoulder side wall, the part of the lateral cover plate 3 located behind the lateral V-shaped cavity 5 and closely attached to the shoulder side wall can smooth the concrete on the surface of the shoulder side wall, thereby realizing the feeding, smoothing and finishing of the shoulder side wall.

[0022] Please refer to Figure 8 and Figure 9 , Figure 12 and Figure 13 As shown, the lateral movable plate 7 is rotatably mounted inside the lateral arc-shaped cavity 4 via the lateral central shaft 8. The lateral central shaft 8 and the lateral cover plate 3 are interference-fitted to improve the airtightness between them and the lateral cover body. The end of the lateral movable plate 7 away from the center of the lateral arc-shaped cavity 4 is in contact with the inner wall of the lateral arc-shaped cavity 4. When the lateral movable plate 7 swings towards the lateral feeding channel 6, it can pat the concrete located in front of the lateral V-shaped cavity 5 towards the side of the shoulder. By swinging the lateral movable plate 7 towards the side wall of the shoulder, the concrete located in the area in front of the lateral V-shaped cavity 5 is patted and squeezed towards the surface of the side wall of the shoulder, so that the concrete can adhere more effectively to the surface of the shoulder and is not easy to fall off, thus improving the feeding effect on the side wall of the shoulder.

[0023] Please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the reciprocating dual-cylinder power structure 9 is mounted on the side cover plate 3 and is connected to the side plate body via a drive assembly. The reciprocating dual-cylinder power structure 9 drives the side movable plate 7 to reciprocate and pound the concrete via the drive assembly. The reciprocating dual-cylinder power structure 9 can adopt the structure of a reciprocating dual-cylinder engine in the prior art to provide a stable driving force for the side movable plate 7 to pound the concrete.

[0024] Please refer to Figure 2 and Figure 3 , Figure 5 , Figures 7 to 9 , Figure 12 and Figure 13 As shown, the drive assembly includes a first plate 10, a second plate 11, a torsion spring 12, a rotating ring 13, a protrusion 14, and a toothed ring 15. The first plate 10 and the second plate 11 are both rotatably sleeved on the top end of the lateral central shaft 8, and the first plate 10 is fixedly connected to the lateral movable plate 7. The torsion spring 12 is disposed between the first plate 10 and the second plate 11. Please refer to Figures 2 to 7As shown, the rotating ring 13 is rotatably mounted on the top of the side cover plate 3. Several protrusions 14 are equidistantly arranged on the surface of the rotating ring 13. When the rotating ring 13 drives the protrusions 14 to pass over the first plate 10, the protrusions 14 push the first plate 10 to rotate and compress the torsion spring 12, thus storing force for the side movable plate 7 to beat the concrete. The toothed ring 15 is fixed to the bottom end of the rotating ring 13 and meshes with the gear on the reciprocating double cylinder power structure 9.

[0025] A reciprocating twin-cylinder power structure 9 drives the gear ring 15 to rotate, which in turn drives the rotating ring 13 to rotate, causing each protrusion 14 to pass over the first plate 10 in sequence. During the process of the protrusion 14 passing over the first plate 10, it first pushes the first plate 10 to rotate, compressing the torsion spring 12 and storing its force. When the protrusion 14 separates from the first plate 10, the elastic force of the torsion spring 12 causes the first plate 10 to rotate rapidly. The first plate 10 then drives the lateral movable plate 7 to rotate rapidly. The lateral movable plate 7 can slap the concrete in front of the lateral V-shaped groove onto the shoulder sidewall, making the concrete adhere more firmly to the shoulder sidewall. Therefore, as each protrusion 14 passes over the first plate 10 in sequence, continuous slapping of the concrete is achieved, greatly improving the concrete replenishment effect.

[0026] Please refer to Figure 8 , Figure 10 and Figure 11 As shown, a cylindrical side feeding bin 16 is provided inside the side cover plate 3. The side feeding channel 6 is connected to the side feeding bin 16. A side rotating cylinder 17 is rotatably installed inside the side feeding bin 16. The side of the side rotating cylinder 17 is provided with a side discharge port 18 that is adapted to the side feeding channel 6. The side rotating cylinder 17 can be rotated to control the side discharge port 18 to be aligned or staggered with the side feeding channel 6. The side wall of the side rotating cylinder 17 is provided with an arc-shaped through hole 19. The center angle of the through hole 19 is adapted to the rotation angle of the side rotating cylinder 17. A side feed pipe 20 is connected to the side wall of the hopper 1. The bottom end of the side feed pipe 20 passes through the side cover plate 3 and extends into the through hole 19. A switch valve 21 is provided on the side feed pipe 20.

[0027] By opening the switch valve 21, the concrete in the hopper 1 can enter the side feed hopper 16 from the side feed pipe 20, thereby pre-filling the side feed hopper 16 with concrete. After that, the switch valve 21 is closed.

[0028] When workers observe that the shoulder sidewall needs additional concrete, the lateral rotating drum 17 is rotated to its maximum angle. At this point, the lateral discharge port 18 connects with the lateral replenishment channel 6. Concrete in the lateral replenishment bin 16 enters the lateral arc-shaped cavity 4 through the lateral replenishment channel 6. As the amount of concrete entering increases, the concrete completely fills the portion of the lateral arc-shaped cavity 4 located inside the first plate 10 and the entire lateral V-shaped cavity 5. Furthermore, when the lateral arc-shaped cavity 4 passes through the area of ​​the shoulder that needs additional concrete, the concrete in the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5 adheres to the surface of the shoulder sidewall, and combined with the patting action of the first plate 10, effective replenishment is achieved.

[0029] When no concrete replenishment is needed, the lateral rotating drum 17 can be rotated, causing the lateral discharge port 18 and the lateral replenishment channel 6 to be misaligned, thereby locking the concrete in the lateral replenishment bin 16. The concrete located in the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5, after contacting the surface of the shoulder sidewall, will be pushed forward by the portion of the lateral cover plate 3 located behind the lateral V-shaped cavity 5.

[0030] Please refer to Figure 2 , Figures 4 to 7 , Figure 10 and Figure 11 As shown, a piston body 22 that moves up and down is provided at the top of the inner cavity of the lateral rotating drum 17. A first guide ball 23 is provided on the side surface of the piston body 22, and a first spiral groove 24 is provided at the top of the inner wall of the lateral rotating drum 17. When the first guide ball 23 moves from the bottom end to the top end of the first spiral groove 24, it drives the lateral rotating drum 17 to rotate and align the lateral discharge port 18 with the lateral feeding channel 6. When the lateral discharge port 18 and the lateral feeding channel 6 are misaligned, the piston body 22 is in the lowest position. When the piston body 22 moves upward, it drives the first guide ball 23 to move upward within the first spiral groove 24. During this process, the piston body 22 drives the lateral rotating drum 17 to rotate, causing the lateral discharge port 18 to move towards the lateral feeding channel 6. When the piston body 22 moves upward to the highest position, the first guide ball 23 moves to the top end of the first spiral groove 24. At this time, the lateral discharge port 18 and the lateral feeding channel 6 are aligned.

[0031] Please refer to Figure 2 , Figures 4 to 7 , Figure 10 and Figure 11As shown, a piston rod 25 is provided at the top of the piston body 22, extending through the top of the side cover plate 3. Both the piston rod 25 and the piston body 22 have a central hole 26, into which a downstream pressure pipe 27 is inserted. The downstream pressure pipe 27 supplies air into the side feeding chamber 16, pressurizing it. This causes the piston body 22 to move upward under pressure, controlling the rotation of the side rotating drum 17. In other words, when the pressure inside the side feeding chamber 16 increases, the pressure automatically controls the connection between the side discharge port 18 and the side feeding channel 6. When the pressure decreases, the piston body 22 moves downward, causing the side rotating drum 17 to rotate in the opposite direction, reducing the overlap between the side discharge port 18 and the side feeding channel 6. In summary, pressure can be used to control the amount of concrete entering the side arc-shaped cavity 4 and the side V-shaped cavity 5.

[0032] Please refer to Figure 2 , Figures 4 to 6 As shown, the front ends of both cylinders of the reciprocating twin-cylinder power structure 9 are connected to upstream pressure pipes 28. One-way valves are installed within the upstream pressure pipes 28, and the output ends of both upstream pressure pipes 28 are connected to the upstream end of the downstream pressure pipe 27. The upstream pressure pipes 28 are U-shaped, with their two ends connected to the air outlets of the two cylinders of the reciprocating twin-cylinder power structure 9, respectively. Using the reciprocating twin-cylinder power structure 9 and the cooperation of the upstream pressure pipes 28 and the one-way valves, when one cylinder supplies gas into the upstream pressure pipe 28, the one-way valve at the other end of the upstream pressure pipe 28 is closed. The gas then passes through the downstream pressure pipe 27 and enters the side feed chamber 16, thereby pressurizing the side feed chamber 16.

[0033] Please refer to Figure 3 , Figure 5 , Figure 7 and Figure 12 As shown, a locking plate 29 is slidably disposed on the side cover plate 3. The locking plate 29 engages with the toothed ring 15 by displacing to one side of the toothed ring 15. A return spring 30 is disposed on the side of the locking plate 29 away from the toothed ring 15. A rotating plate 31 is rotatably connected to the side cover plate 3, and one end of the rotating plate 31 extends to the front side of the first plate body 10. When the first plate body 10 contacts the rotating plate 31, its forward swing stroke is greater than the maximum stroke driven by the protrusion 14 to swing forward. When the first plate body 10 pushes the rotating plate 31 forward to rotate, the rotating plate 31 drives the locking plate 29 to displace and engage with the toothed ring 15. The top of the crank connecting rod shaft of the reciprocating double cylinder power structure 9 is connected to a handle 32.

[0034] During the process of adding concrete to the sidewall of the shoulder guard, when the overall pressure in the lateral arc cavity 4, the lateral V-shaped cavity 5, and the lateral replenishment bin 16 is too high, the pressure will cause the concrete in the lateral arc cavity 4 to push the lateral movable plate 7 to continuously compress the torsion spring 12 and swing forward. The lateral movable plate 7 will drive the first plate 10 to swing synchronously, so that the first plate 10 can pass the critical position of forward swing during normal patting and push the inner end of the rotating plate 31, causing the rotating plate 31 to rotate. When the rotating plate 31 rotates, it will stretch the return spring 30 and push the locking plate 29 to move towards the toothed ring 15, so that the locking plate 29 is inserted into the toothed groove of the toothed ring 15. At this time, the locking plate 29 can lock the toothed ring 15, so that the reciprocating double cylinder power structure 9 can no longer pressurize the replenishment bin, and the worker cannot turn the rotating handle 32 even if he applies force to it.

[0035] Therefore, the reciprocating double-cylinder kiln structure can be automatically locked and pressurization stopped when the pressure in the replenishment hopper is too high. As the slipform machine 2 moves forward, the concrete in the lateral arc cavity 4 and the lateral V-shaped cavity 5 will gradually decrease when passing through the area of ​​the shoulder sidewall that needs to be replenished with concrete, thus achieving the pressure relief process.

[0036] During the depressurization process, both the locking plate 29 and the rotating plate 31 are reset by the action of the return spring 30, causing the locking plate 29 to separate from the toothed ring 15. At the same time, the piston body 22 loses pressure support and moves downward, driving the lateral rotating cylinder 17 to rotate, causing the lateral discharge port 18 to be misaligned with the lateral feeding channel 6, stopping the lateral feeding bin 16 from continuing to feed concrete into the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5.

[0037] In this embodiment, the reciprocating dual-cylinder power structure 9 is driven by the worker rotating the handle 32. Therefore, when the pressure is too high, the locking block locks the gear ring 15, preventing the worker from continuing to rotate the handle 32. Compared with other methods that use external power, this method is safer and simpler in structure, and it can automatically help the worker judge the material supply status.

[0038] Specifically, in this embodiment, a strip groove is provided on the outer end of the rotating plate 31, and the outer end of the rotating plate 31 passes through the locking block. A sliding rod that can slide within the strip groove is provided inside the locking block. Therefore, when the rotating plate 31 rotates, the locking block can be driven to move through the cooperation of the strip groove and the sliding rod.

[0039] Please refer to Figure 5 , Figure 7 , Figure 12 and Figure 13As shown, a rod sleeve 33 is fixedly installed at the top of the rotating plate 31, and a rod 34 is inserted into the top of the rod sleeve 33. A second spiral groove 35 is provided on the inner wall surface of the rod sleeve 33, and a second guide ball 36 is provided on the side surface of the rod 34. The second guide ball 36 slides in cooperation with the second spiral groove 35. The top of the rod 34 is fixedly connected to the top of the piston rod 25 through the support plate 37. When the first guide ball 23 moves to the top of the first spiral groove 24, the second guide ball 36 drives the rod sleeve 33 to rotate 180° through the second spiral groove 35. When the first guide ball 23 is located at the bottom of the first spiral groove 24, the end of the lateral movable plate 7 away from the lateral central axis 8 is located at the front end of the lateral arc cavity 4 and contacts the side wall of the shoulder guard, which can perform a scraping operation on the side wall of the shoulder guard.

[0040] During the forward movement of the slipform machine 2, the portion of the side cover plate 3 located in front of the side arc cavity 4 slides close to the surface of the shoulder sidewall, smoothing and finishing the shoulder surface to a certain extent. Meanwhile, the side movable plate 7, using its right-angle corner, scrapes against the shoulder sidewall to remove excess concrete from the shoulder surface. The cleaned concrete then enters the side arc wall. When concrete needs to be replenished next time, the side movable plate 7 rotates to the side of the side replenishment channel 6, allowing the scraped concrete to be used as part of the replenishment concrete.

[0041] Furthermore, when smoothing and finishing the surface of the shoulder guard, the scraping and sweeping operation of the shoulder guard surface can be combined with the smoothing operation of the added concrete, which can be adjusted according to actual needs and improve the use effect.

[0042] When the piston body 22 moves upward under pressure, it drives the insertion rod 34 to move upward through the piston rod 25. During this process, the second guide ball 36 moves upward within the second spiral groove 35, causing the rod sleeve 33 to rotate. The rod sleeve 33 then drives the second plate 11 to rotate, and the second plate 11 pushes the first plate 10 to rotate through the torsion spring 12. The first plate 10 then drives the lateral movable plate 7 to rotate. Specifically, in this embodiment, when the lateral discharge port 18 and the lateral feeding channel 6 switch from a misaligned state to an aligned state, the lateral movable plate 7 rotates from the front end of the lateral arc cavity 4 to the rear end, that is, it switches from the position of the hanging sweeping state to the position of the tapping state.

[0043] When the pressure inside the lateral feed chamber 16 decreases, the piston body 22 moves upward, causing the rotating drum to reset and reducing the amount of concrete replenished. During this process, the insert rod 34 moves upward within the rod sleeve 33, causing the second plate 11 to rotate forward. At this time, the second plate 11 can pull the first plate 10 forward via the torsion spring 12, and the lateral movable plate 7 will swing forward to increase the rear space of the lateral arc-shaped cavity 4, achieving further pressure relief and improving pressure relief efficiency. Especially when the pressure inside the lateral feed chamber 16 is too high, causing the reciprocating double-cylinder power structure 9 to lock and stop pressurizing the lateral feed chamber 16, the forward swing of the lateral movable plate 7 can achieve the pressure relief process more quickly, improving the performance.

[0044] Please refer to Figure 12 and Figure 13 As shown, an inner lifting rod 38 capable of being raised and lowered is inserted into the top of the insertion rod 34. A connecting plate 39 is fixedly connected to the top of the inner lifting rod 38. An outer lifting rod 40 is fixedly connected to the end of the connecting plate 39 away from the inner lifting rod 38. The outer lifting rod 40 is mounted on the side cover plate 3 in a way that allows it to be raised and lowered. A rotating plate 31 is rotatably mounted on the bottom end of the outer lifting rod 40. The outer lifting rod 40 can drive the rotating plate 31 to be raised and lowered. When the rotating plate 31 is in its lowest position, it is located below the first plate 10, and the support plate 37 is located below the connecting plate 39; when the second guide ball 36 moves upward in the second spiral groove 35, causing the first plate 10 to rotate to the rear side of the rotating plate 31, the top of the support plate 37 contacts the bottom of the connecting plate 39.

[0045] This configuration allows the lateral movable plate 7 to rotate backward as the first plate 10 drives it, and after passing the rotating plate 31, the rotating plate 31 rises to a height that can be pushed by the first plate 10. During the reset process, the rotating plate 31 first descends to a height lower than the first plate 10, and then the first plate 10 moves forward past the inner end of the rotating plate 31.

[0046] Specifically, during the upward displacement of the insertion rod 34 and the passage of the first plate 10 past the front of the rotating plate 31, the insertion rod 34 moves upward outside the inner lifting rod 38, and the support plate 37 does not push against the connecting plate 39. After the first plate 10 moves to the rear position of the rotating plate 31, the support plate 37 pushes against the connecting plate 39, and during the subsequent rotation of the first plate 10, the connecting plate 39 drives the rotating plate 31 to rise to its highest position through the outer lifting rod 40. At this time, the rotating plate 31 is supported by the support plate 37 in the height direction.

[0047] Please refer to Figure 10 , Figure 11 and Figure 13As shown, the bottom ends of the first spiral groove 24 and the second spiral groove 35 are both connected to longitudinal straight grooves 41. When the first guide ball 23 and the second guide ball 36 are at their lowest positions, they are both located at the bottom ends of the longitudinal straight grooves 41. A compression spring 42 is provided between the top of the piston and the inner top wall of the side cover plate 3. By setting the longitudinal straight grooves 41, when the reciprocating double-cylinder power structure 9 pressurizes the side feed bin 16, the first guide ball 23 and the second guide ball 36 will move in the corresponding longitudinal straight grooves 41 respectively. During this process, the side rotating cylinder 17 will not rotate, and the compression spring 42 will be compressed. As the pressure in the side feed bin 16 increases, concrete will enter the side arc cavity 4 and the side V-shaped cavity 5 and fill them, so as to ensure that the concrete effectively covers the side wall of the shoulder in the height direction.

[0048] The downward pressure provided by the compression spring 42 to the piston body 22 allows the piston body 22 to move downwards in real time when the pressure in the lateral feeding chamber 16 decreases, improving its responsiveness. Furthermore, when the pressure in the feeding chamber is too high and the reciprocating dual-cylinder power structure 9 stops pressurizing, the force of the compression spring 42 allows the piston body 22 to provide a certain amount of pressure to the lateral feeding chamber 16, ensuring that the concrete in the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5 adheres tightly to the surface of the shoulder sidewall, ensuring a good adhesion effect.

[0049] Please refer to Figure 6 and Figure 8 As shown, the heights of the lateral arc-shaped cavity 4, the lateral V-shaped cavity 5, the lateral feeding channel 6, and the lateral movable plate 7 are all greater than the height of the shoulder guard. A sealing plate 43 is provided on the inner side of the lateral cover plate 3 above the top of the shoulder guard. The sealing plate 43 closes the area of ​​the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5 above the shoulder guard. A smearing plate 44 that slides on the top of the shoulder guard is fixedly connected between the bottom of the opposite sides of the two sealing plates 43. The hopper 1 is fixedly installed on the top of the smearing plate 44.

[0050] The sealing plate 43, in conjunction with the smoothing plate 44, improves the airtightness of the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5, ensuring that the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5 completely cover the shoulder guard in the height direction, thus improving the smoothing effect. Simultaneously, the smoothing plate 44, under the influence of gravity, can smooth the top of the shoulder guard. Therefore, combined with the side cover plate 3, it can simultaneously smooth the top and both sides of the shoulder guard, improving the shoulder guard forming effect.

[0051] Please refer to Figure 2 , Figure 4 , Figure 14 and Figure 15As shown, a top V-shaped cavity 45 is formed between the front end of the smearing plate 44 and the top of the shoulder guard. A top feeding channel 46 is provided at the front end of the smearing plate 44. A top feeding bin 47 is provided at the top of the smearing plate 44. A top rotating cylinder 48 is rotatably installed inside the top feeding bin 47. A top discharge port 49 adapted to the top feeding channel 46 is provided on the side of the top rotating cylinder 48. Both ends of the top feeding bin 47 are provided with operating handles 50 whose inner ends are rotatably fixed to the top. A top discharge trough 51 communicating with the top bin is provided on the front side of the bottom of the hopper 1.

[0052] When the operating handle 50 is turned backward to the limit position, the top discharge port 49 rotates with the top and can communicate with the top discharge chute 51. The concrete in the hopper 1 will enter the top filling hopper 47 through the top discharge chute 51 and the top discharge port 49, and fill the top filling hopper 47.

[0053] When a worker observes that there is a lack of concrete at the top of the shoulder guard and that concrete needs to be added, he turns the operating handle 50 forward to the limit position, so that the top rotating cylinder 48 rotates to the state where the top discharge port 49 is aligned with the top replenishment channel 46. At this time, the concrete in the top replenishment bin 47 can fall from the bottom replenishment channel into the top of the shoulder guard and be located in the top V-shaped cavity 45. As the trowel 44 moves forward, it can press down the concrete in the top V-shaped cavity 45 and smooth it on the top of the shoulder guard, completing the process of adding concrete to the top of the shoulder guard and smoothing and finishing the surface.

[0054] Please refer to Figure 6 , Figure 8 and Figure 10 As shown, the bottom of the lateral arc-shaped cover is provided with two door panels. One door panel is circular and is threadedly installed at the bottom of the lateral replenishment bin 16. The other door panel is bolted to the top of the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5. By removing the two door panels, the lateral replenishment bin 16, the lateral arc-shaped cavity 4 and the lateral V-shaped cavity 5 can be cleaned.

[0055] The technical scope of this invention is not limited to the contents of the above specification. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the scope of this invention.
