Description

Technical Field

[0001] The invention relates to the technical field of precast concrete components, and in particular to a concrete placing machine and a production line of concrete components. Background Art

[0002] Concrete placing boom is a commonly used equipment on precast concrete component production lines. At present, concrete placing booms usually unload materials by feeding materials in a feeding trough with a screw shaft and discharging materials through a side door. That is, a screw shaft is arranged in the feeding trough, and a side opening is arranged at a position corresponding to the end of the feeding trough and the end of the screw shaft. The screw shaft pushes concrete to the side opening, and the concrete flows from the side opening to the formwork table to realize the distribution of concrete.

[0003] However, in some application scenarios, such as in the initial stage of concrete distribution, the screw shaft is difficult to push the concrete to the side opening in time, so that the concrete distribution machine discharges discontinuously in the initial stage of concrete distribution, often resulting in a lack of material or insufficient material in the front section of the concrete component;

[0004] In some application scenarios, such as when the fluidity of concrete is poor, concrete is prone to accumulate or get stuck in the feed trough, causing uneven material discharge from the concrete placing machine, often leading to a lack of material or insufficient material in some parts of the concrete component and excessive material in some parts.

[0005] Therefore, the existing concrete placing boom has the problem of poor discharging continuity and uniformity. Summary of the invention

[0006] In view of this, the present invention provides a concrete placing boom and a production line for concrete components to solve the problem of poor continuity and uniformity of concrete placing boom.

[0007] In a first aspect, the present invention provides a concrete placing machine, comprising a frame, a placing hopper supported on the frame, a feeding device and a discharge hopper arranged at the bottom of the placing hopper. Specifically, an opening is provided at the bottom of the placing hopper; the feeding device comprises a feeding shell and a feeding shaft arranged in the feeding shell, a spiral blade is provided on the outer peripheral side of the feeding shaft, the feeding shell has a feeding inlet and a feeding outlet, and the feeding inlet is connected to the opening. Furthermore, the discharge hopper is suitable for storing concrete and has a feeding port and a discharging port connected to each other, the feeding port is connected to the feeding outlet, the opening direction of the discharging port faces downward, and a switch structure is provided at the discharging port, and the switch structure is suitable for opening or closing the discharging port.

[0008] Beneficial effects: In this solution, the discharge hopper has the functions of material leveling and material storage, so that the material is evenly distributed and continuously supplied throughout the entire discharge range. At the beginning of the material distribution, the feed shaft rotates, and under the action of the spiral blades on its outer side, the concrete in the distribution hopper is fed from the feed outlet to the discharge hopper. The concrete collapses and mixes in the discharge hopper, so that the entire discharge width of the discharge hopper is filled with concrete, avoiding the lack of material at the initial moment of distribution and resulting in discontinuous or uneven distribution. In addition, even if the feed shaft accumulates or gets stuck in the feed housing, the material can still be distributed continuously and evenly under the action of the discharge hopper. Therefore, the concrete distribution machine of this solution greatly improves the continuity and uniformity of the material distribution.

[0012] Beneficial effect: The discharge hopper is constructed as a flat bucket-shaped structure, and the bottom is a constricted section, that is, the discharge port is flat. With the discharge hopper configured in this way, the material discharged from the discharge port is in the shape of a flat belt. When the mold platform is rotated at a predetermined speed, the concrete that collapses onto the mold platform is a uniform and flat concrete belt. The thickness of the concrete is related to the rotation speed of the mold platform, so the discharge amount of the discharge hopper can be accurately controlled. In addition, in this solution, the opening size of the discharge port is adjusted by the adjusting member, so that the opening size of the discharge port can be adaptively adjusted according to the rotation speed of the mold platform to meet the discharge amount requirements.

[0013] In an optional embodiment, the feeding shell includes an upper shell and a lower shell, one end of the lower shell is hinged to the distribution hopper, and the other end is detachably connected to the distribution hopper; grooves are provided at the bottom of the upper shell and the top of the lower shell, the feeding shaft is correspondingly arranged in the grooves, and the discharge hopper is arranged at the bottom of the lower shell.

[0014] Beneficial effect: grooves are provided at the bottom of the upper shell and the top of the lower shell, and the feed shaft is arranged in the grooves. When the feed shaft needs to be cleaned, open one end of the lower shell that is detachably connected to the cloth hopper, and rotate the lower shell around the other end to expose the internal feed shaft, which is convenient for cleaning the internal feed shaft.

The discharge hopper has a material receiving position abutting against the bottom of the lower half shell and an avoidance position away from the lower half shell; the driving structure is suitable for driving the discharge hopper to move between the material receiving position and the avoidance position.

[0018] Beneficial effect: Such arrangement can simplify the structure of the lower half shell, facilitate opening the lower half shell and revealing the internal feeding shaft, thereby ensuring the convenience of cleaning.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0046] Combine the following Figures 1 to 13 , describing an embodiment of the present invention.

[0047] On the one hand, the present invention provides a concrete placing boom, comprising a frame 1, a placing hopper 2 supported on the frame 1, a feeding device 3 and a discharge hopper 4 arranged at the bottom of the placing hopper 2.

[0048] Specifically, the top of the material distribution hopper 2 is arranged above the frame 1 and is open at the top for adding concrete into the material distribution hopper 2 , and an opening 21 is arranged at the bottom of the material distribution hopper 2 .

[0049] Furthermore, the feeding device 3 includes a feeding shell and a feeding shaft 31 arranged in the feeding shell. The outer peripheral side of the feeding shaft 31 is provided with spiral blades. The feeding shell has a feeding inlet and a feeding outlet 331. The feeding inlet is connected to the above-mentioned opening 21.

[0050] Furthermore, the discharge hopper 4 is suitable for storing concrete and has a connected feed port 411 and a discharge port 421, the feed port 411 is connected to the feeding outlet 331, the opening direction of the discharge port 421 is downward, and a switch structure 43 is correspondingly provided at the discharge port 421, and the switch structure 43 is suitable for opening or closing the discharge port 421.

[0051] In this embodiment, the discharge hopper 4 has the functions of material leveling and material storage, so that the material is evenly distributed and continuously supplied throughout the entire discharge range. At the beginning of material distribution, the feed shaft 31 rotates, and under the action of the spiral blades on its outer side, the concrete in the distribution hopper 2 is fed into the discharge hopper 4 from the feed outlet 331. The concrete collapses and mixes in the discharge hopper 4, so that the entire discharge width of the discharge hopper 4 is filled with concrete, avoiding the situation where the material is lacking at the initial moment of distribution and the material is discontinuous or uneven. In addition, even if the feed shaft 31 accumulates or gets stuck in the feeding shell, the material can still be distributed continuously and evenly under the action of the discharge hopper 4. Therefore, the concrete distributor of this embodiment greatly improves the continuity and uniformity of material distribution.

[0052] On the other hand, the opening 21 of the discharge hopper 4 faces downward, so that the concrete can fall by its own weight during discharge, thereby preventing the discharge hopper 4 from being accumulated or stuck.

[0053] It should be noted that the present embodiment does not impose any specific limitation on the size of the discharge hopper 4, as long as it can match the material distribution speed and achieve continuous, uniform and accurate material discharge.

[0054] In some embodiments, when distributing concrete, the concrete placing machine is fixed on the distributing station, and the mold platform 8 rotates in the opposite direction of the distributing direction at a preset speed. The concrete placing machine discharges concrete onto the mold platform 8 to achieve distributing concrete. At this time, the width of the discharge port 421 of the discharge hopper 4 depends on the rotation speed of the mold platform 8, and the length of the discharge port 421 depends on the width of the mold on the mold platform 8. Figure 1 As shown in the example, direction A is the material distribution direction, and the flow direction of the mold table 8 is opposite to direction A. It can be understood that the material distribution direction A referred to in this solution is the material distribution direction for the produced components, that is, the direction in which the components are distributed on the mold table 8.

[0055] Specifically, in some embodiments, the discharge hopper 4 is constructed as a flat bucket-shaped structure, and the top of the discharge hopper 4 has a flared section 41, and the flared section 41 forms a feed port 411 with an upward opening; the bottom of the discharge hopper 4 has a constricted section 42, and the constricted section 42 forms a discharge port 421 with a downward opening. The discharge hopper 4 is configured in this way, and the discharge port 421 is flat. When discharging, the discharge of the discharge port 421 is in a flat belt shape. When the formwork 8 flows at a predetermined speed, the concrete that collapses onto the formwork 8 is a uniform and flat concrete belt. The thickness of the concrete is related to the flow speed of the formwork 8, so the discharge amount of the discharge hopper 4 can be accurately controlled.

[0056] Exemplarily, the middle portion of the discharge hopper 4 also has a connecting section, and the expanding section 41, the connecting section and the shrinking section 42 are integrally formed.

[0057] Furthermore, the discharge hopper 4 further includes an adjusting member, which is suitable for adjusting the opening size of the discharge port 421. It should be noted that, in this embodiment, the adjusting member is mainly used to adjust the opening size of the discharge port 421 along the direction A, that is, the width size of the discharge port 421. Under the action of the adjusting member, the width of the discharge port 421 can be adaptively adjusted according to the flow speed of the die table 8 to meet the demand for the discharge amount.

[0058] Exemplarily, the adjusting member may be a partition, which is inserted into the discharge hopper 4 along the length direction of the discharge hopper 4 (i.e., the direction perpendicular to the material distribution direction A), and is movably arranged along the width direction of the discharge hopper 4 (i.e., the material distribution direction A). By adjusting the position of the partition in the discharge hopper 4, the width of the discharge port 421 can be adjusted.

[0059] For example, the adjusting member may also be a baffle, which is slidably connected to the bottom of the constricted section 42, that is, the position where the discharge port 421 is located. The length of the baffle matches the length of the discharge port 421, and is suitable for sliding along the width direction of the discharge port 421. By adjusting the position of the baffle at the discharge port 421, the width of the discharge port 421 can be adjusted.

[0060] Exemplarily, the adjusting member may also be a sliding mechanism, the discharge hopper 4 includes a first side plate and a second side plate along the width direction, and the sliding mechanism is suitable for adjusting the distance between the first side plate and the second side plate to adjust the width of the discharge port 421 .

[0061] Furthermore, the length of the discharge port 421 can be equal to the width of the mold platform 8, so as to realize one-time distribution and improve distribution efficiency.

[0062] The method of using the concrete placing machine is as follows: start the feeding shaft 31, and the spiral blades of the feeding shaft 31 feed the concrete to the feeding outlet 331; the concrete enters the discharge hopper 4 from the feeding port 411; the switch structure 43 opens the discharge port 421; the mold table 8 rotates and the material is discharged at the discharge port 421; after the unloading is completed, the switch structure 43 closes the discharge port 421.

[0063] In some embodiments, the feeding shell is formed with two feeding outlets 331, and the two feeding outlets 331 are arranged at intervals in a straight line; correspondingly, the concrete placing machine is provided with two discharge hoppers 4, and the feed ports 411 of the two discharge hoppers 4 are respectively connected to one of the feeding outlets 331, so as to facilitate the placing of two components at the same time.

[0064] In some embodiments, the switch structure 43 includes a first baffle 431 and a first driving member 432. The first baffle 431 is hinged to the discharge hopper 4. The first baffle 431 has a closed position covering the discharge port 421 and an open position exposing the discharge port 421. The first driving member 432 is connected to the first baffle 431. The first driving member 432 is suitable for driving the first baffle 431 to swing between the open position and the closed position. It not only has a simple structure, but also can be automatically controlled, which is convenient for timely control of the on and off of the discharge of the discharge hopper 4.

[0065] Exemplarily, the first baffle 431 may be configured as a plate-like structure, and the size thereof may be slightly larger than the size of the discharge port 421. Exemplarily, the first baffle 431 may also be configured as a "U" shape, and the two sides along the length direction are respectively hinged to the two sides of the discharge hopper 4. Exemplarily, the first driving member 432 may be a cylinder.

[0066] In some embodiments, the feed housing includes an upper half shell 32 and a lower half shell 33, one end of the lower half shell 33 is hinged to the material distribution hopper 2, and the other end is detachably connected to the material distribution hopper 2; a groove 332 is provided at the bottom of the upper half shell 32 and the top of the lower half shell 33, and the feed shaft 31 is correspondingly arranged in the groove 332, and the discharge hopper 4 is arranged at the bottom of the lower half shell 33. When it is necessary to clean the feed shaft 31, open one end of the lower half shell 33 detachably connected to the material distribution hopper 2, and rotate the lower half shell 33 around the other end to expose the internal feed shaft 31, so as to facilitate cleaning of the internal feed shaft 31.

[0067] It is understandable that the shapes of the groove 332 of the upper shell 32 and the groove 332 of the lower shell 33 are adapted to each other, so as to provide an independent accommodating cavity for the feeding shaft 31 .

[0068] Exemplarily, the feeding device 3 includes a plurality of feeding shafts 31, and the plurality of feeding shafts 31 are arranged at intervals. A plurality of grooves 332 are correspondingly provided at the bottom of the upper shell 32 and the top of the lower shell 33, and a plurality of independent accommodating cavities are formed. The plurality of feeding shafts 31 are respectively arranged in one of the accommodating cavities, and each feeding shaft 31 can work independently, and the working state of the feeding shaft 31 can be adaptively adjusted according to the width of the cloth.

[0069] Exemplarily, the concrete placing machine further includes a stirring device 7, and the stirring device 7 includes a stirring shaft 71, and the stirring shaft 71 is arranged above the feeding shaft 31 and is arranged perpendicular to the feeding shaft 31. Exemplarily, there is one stirring shaft 71. Alternatively, along the height direction of the placing hopper 2, two stirring shafts 71 are arranged at intervals up and down, and the stirring shaft 71 at a high position fully stirs the concrete in the placing hopper 2 to prevent the concrete from segregating in the placing hopper 2; the stirring shaft 71 at a low position can achieve the effect of homogenizing the material, that is, to push the concrete in the middle of the placing hopper 2 evenly to both sides.

[0070] Exemplarily, the top of the distribution hopper 2 is mounted on the frame 1, and a weighing sensor is provided between the distribution hopper 2 and the frame 1 to weigh the weight of the concrete in the distribution hopper 2, thereby controlling the discharge amount of the concrete distribution boom.

[0071] Exemplarily, the material distribution hopper 2 is constructed as an asymmetric bucket structure, so that the physical center of gravity of the material distribution hopper 2 coincides with the geometric center of gravity, especially when loaded, the two centers of gravity tend to coincide more, so as to facilitate the accurate weighing of the above-mentioned weighing sensor, and then realize precise control of unloading.

[0072] Furthermore, the discharge hopper 4 can be directly installed on the bottom of the lower half shell 33 , or can be against the bottom of the lower half shell 33 .

[0073] Specifically, in some embodiments, see Figures 1 to 7The lower half shell 33 includes a feeding part 33a and a discharging part 33b which are arranged in sequence. The feeding part 33a is provided with a groove 332, and the discharging part 33b is provided with a feeding outlet 331. The discharge hopper 4 is connected to the bottom of the discharging part 33b, and one end of the first driving member 432 is connected to the bottom of the feeding part 33a. In this way, the connection between the discharge hopper 4 and the lower half shell 33 is tight, which prevents the concrete from flowing out from the connection between the two.

[0074] Exemplarily, both sides of the flared section 41 of the discharge hopper 4 are provided with connecting ears, and the two connecting ears are respectively bolted to the lower half shell 33. Exemplarily, both sides of the discharge hopper 4 can also extend with folded edges, and the two folded edges are respectively bolted or welded to the lower half shell 33.

[0075] Exemplarily, the first driving member 432 can be a cylinder, the fixed end of the first driving member 432 is hinged to the bottom of the feeding part 33a, and the telescopic end is hinged to the first baffle 431. The first driving member 432 drives the first baffle 431 to swing between the open position and the closed position through its own telescopic movement.

[0076] In some embodiments, see Figures 10 to 13 The concrete placing machine further includes a driving structure 44, a feeding outlet 331 is formed at the end of the groove 332, and a discharge hopper 4 is arranged to be movable up and down and is arranged corresponding to the end of the groove 332. The discharge hopper 4 has a receiving position abutting against the bottom of the lower half shell 33 and an escape position away from the lower half shell 33; the driving structure 44 is suitable for driving the discharge hopper 4 to move between the receiving position and the escape position. Such an arrangement can simplify the structure of the lower half shell 33, facilitate the lower half shell 33 to open and leak the feeding shaft 31 inside, and ensure the convenience of cleaning.

[0077] For example, the driving structure 44 may be driven by a cylinder or a linear motor.

[0078] For details on what can be achieved, see Fig.12 and Fig.13 The concrete placing machine also includes a lifting frame 45 and two fixing frames 46. The discharge hopper 4 is installed on the lifting frame 45. The two fixing frames 46 are respectively fixedly connected to the frame 1. The driving structure 44 includes two second driving members 441. The two second driving members 441 are fixedly connected to the two fixing frames 46 in a one-to-one correspondence. The driving ends of the two second driving members 441 are fixedly connected to the two ends of the lifting frame 45 along the length direction thereof. The two second driving members 441 drive at the two ends of the lifting frame 45 to improve the stability of the lifting and lowering of the discharge hopper 4.

[0079] Exemplarily, the discharge hopper 4 and the lifting frame 45 can be detachably connected or fixedly connected. Exemplarily, the discharge hopper 4 is provided with folded edges on opposite sides, and the discharge hopper 4 is hung on the lifting frame 45 through the folded edges. Exemplarily, the discharge hopper 4 is welded or bolted to the lifting frame 45.

[0080] For example, see Fig.12 and Fig.13 The concrete placing machine includes a guide mechanism, which is arranged between the lifting frame 45 and the fixed frame 46.

[0081] Specifically, the guide mechanism includes two pairs of guide grooves 471 and sliders 472, which are respectively arranged at the two ends of the lifting frame 45. The guide grooves 471 are fixedly connected to the fixed frame 46, and the sliders 472 are fixedly connected to the lifting frame 45. The lifting frame 45 is suitable for moving up and down in the guide grooves 471 through the sliders 472 at both ends.

[0082] In some embodiments, see Figure 8 and Fig. 9 The concrete placing machine also includes a blocking device 5. Along the placing direction, the blocking device 5 is arranged at the rear side of the discharge port 421. The blocking device 5 includes a bracket 51 and a blocking assembly 52. ​​The bracket 51 is connected to the frame 1 movably up and down, and the blocking assembly 52 is connected to the side of the bracket 51 facing the discharge port 421 to block the concrete after discharge and prevent the concrete after discharge from overflowing.

[0083] In some embodiments, the bracket 51 is directly connected to the frame 1 so as to be movable up and down. For example, the frame 1 is provided with a plurality of connection holes along the height direction, and the bracket 51 is bolted to the plurality of connection holes respectively to achieve the up and down movement.

[0084] In some embodiments, the bracket 51 is indirectly connected to the frame 1 so as to be movable up and down through the lifting frame 45 and the fixing frame 46. Exemplarily, the bracket 51 is bolted to the lifting frame 45, and the bracket 51 is moved up and down by the lifting frame 45. Alternatively, the bracket 51 is connected to the lifting frame 45 so as to be movable up and down.

[0085] More specifically, the enclosure assembly 52 includes a second baffle 521 and two third baffles 522. The second baffle 521 is arranged side by side with the discharge port 421. The two third baffles 522 are respectively arranged at both ends of the second baffle 521. The setting height of the bottom end of the second baffle 521 is higher than the setting height of the bottom end of the third baffle 522. In this way, the second baffle 521 and the third baffle 522 form a three-surrounding shape for the concrete, further improving the effect of preventing the concrete from overflowing. In addition, the bottom end of the second baffle 521 is slightly higher, and the second baffle 521 can play the role of preliminary scraping.

[0086] Exemplarily, the length of the second baffle 521 matches the width of the mold platform 8, and the two third baffles 522 are respectively close to the molds on both sides of the mold platform 8. Exemplarily, the second baffle 521 and the third baffle 522 can be made of rubber plates, or other soft and elastic non-metal plates.
