Description

Technical Field

[0001] The invention belongs to the technical field of automatic bricklaying equipment, and in particular relates to a continuous brick feeding system for bricklaying equipment. Background Art

[0002] With the deepening of population aging and changes in the career choices of young people, the problem of labor shortage will become more and more serious. For the construction of various structures such as blast furnaces, ladles and buildings, it is very necessary to develop automatic masonry equipment to replace manual masonry operations.

[0003] Existing automatic masonry equipment usually needs to cooperate with tower cranes for brick transportation. Usually, a hanging basket is used to load brick stacks and then hoist them to the masonry workbench for stacking and standby. The disadvantage of this stack transportation method is that the brick stack occupies a large space on the masonry workbench, which affects the movement space of the masonry robot. In addition, it is impossible to achieve accurate brick delivery, and the brick transportation volume is poorly matched with the demand of the masonry robot. At the same time, the masonry robot also needs to take into account the stack dismantling action, which affects the efficiency of the masonry operation. Summary of the invention

[0004] The embodiment of the present invention provides a continuous brick feeding system for masonry equipment, aiming to achieve accurate brick feeding, improve the matching degree between the delivered brick quantity and the demanded quantity, thereby improving the working efficiency.

[0005] To achieve the above object, the technical solution adopted by the present invention is: to provide a continuous brick feeding system for masonry equipment, comprising:

[0006] A column is used to be vertically arranged on the frame and support the foundation or the bottom surface of the structure at the bottom end;

[0007] The rotary conveyor line is arranged on the column and forms a reciprocating rotary motion track. A plurality of brick boxes suitable for accommodating bricklaying units are sequentially and spacedly distributed along the rotary motion track.

[0008] A feed conveyor is fixedly connected to the frame in the horizontal direction, one end of the feed conveyor extends out of the frame and is used to receive bricks, and the other end is aligned with the rotary conveyor line and is used to push the bricks into the corresponding brick boxes in sequence;

[0009] The bidirectional conveyor is connected to the column and is spaced apart from the feed conveyor above and below. The bidirectional conveyor is used to sequentially receive bricks in each brick box and transfer the bricks alternately to both ends thereof.

[0010] In one possible implementation, the feed conveyor includes:

[0011] A hanger, fixedly connected to the frame and having a horizontally extending conveying channel;

[0012] A belt conveyor part is connected to the hanger and is located in the conveying channel, and one end of the belt conveyor part extends out of the frame to receive bricklaying;

[0013] A roller conveyor is connected to the hanger and butted against the other end of the belt conveyor, and the roller conveyor is aligned with the rotary conveyor line;

[0014] The pushing assembly is arranged on the roller conveyor and aligned with the rotary conveyor line, and is used for pushing bricks into a brick box which is flush with the height of the roller conveyor.

[0015] In some embodiments, the bidirectional conveyor comprises:

[0016] The mounting seat is encircled by the column and connected to the lifting work platform, and the mounting seat is used to move up and down along the column with the lifting work platform;

[0017] The conveyor frame is fixedly connected to the mounting seat, and a plurality of rollers are sequentially spaced from one end to the other end of the conveyor frame. At least two rollers located in the middle of the conveyor frame are aligned with the rotary conveyor line to receive bricks, and each roller is used to run synchronously in a forward and reverse direction alternately to convey bricks;

[0018] A receiving assembly, which is arranged on the mounting seat and aligned with the rotary conveyor line, is used to sequentially receive bricks in each brick box and place the bricks on the rotating roller in the middle of the conveyor frame;

[0019] Two jacking assemblies are respectively arranged at the two ends of the conveying frame, and the jacking assemblies are used to jack up the bricks on the rollers running to the ends of the conveying frame.

[0020] Exemplarily, the material receiving assembly includes:

[0021] A sliding seat is slidably connected to the mounting seat along the axial direction of the roller, and a lifting member is provided on the sliding seat;

[0022] A receiving frame is connected to the lifting output end of the lifting member, and a plurality of receiving plates are arranged at intervals on the receiving frame, and each receiving plate is suitable for passing through the gap between adjacent rollers and jointly supporting bricklaying;

[0023] A sliding drive member is arranged on the mounting seat and the output end is connected to the sliding seat;

[0024] Among them, when the material receiving rack moves to the position directly below the brick box which is flush with the height of the roller under the drive of the sliding drive member, the lifting member drives the material receiving rack to rise and hold up the bricks in the brick box. When the material receiving rack moves to the position directly above the roller under the drive of the sliding drive member, the lifting member drives the material receiving rack to descend so that the bricks are placed on the roller.

[0025] For example, both ends of the conveying frame are provided with limit stops, which are used to block the bricks from running to the rollers at both ends of the conveying frame; the jacking assembly includes a telescopic drive member and a jacking frame, the telescopic drive member is vertically arranged below the end of the conveying frame, the jacking frame is connected to the output end of the telescopic drive member, and a plurality of top plates are spaced apart on the jacking frame, each of which is suitable for passing through the gap between adjacent rollers and jointly supporting the bricks; wherein the jacking frame is used to lift up the bricks blocked on the side of the limit stop.

[0026] In a possible implementation, the rotary conveyor line includes:

[0027] A rotating driving member is fixedly connected to the column;

[0028] A driving shaft is rotatably connected to the column and connected to the output end of the rotary driving member. The driving shaft is sleeved with two driving wheels at intervals along its axial direction.

[0029] A driven shaft is connected to the column, and is located at the upper and lower ends of the column with the driving shaft respectively. The driven shaft is rotatably connected to two driven wheels, and the two driven wheels correspond to the two driving wheels respectively.

[0030] Two transmission chains are respectively mounted on the corresponding upper and lower driving wheels and driven wheels, and the two transmission chains are commonly connected to each brick box.

[0031] In some embodiments, the brick box includes:

[0032] The box body has a side facing away from the column open to form a brick inlet;

[0033] Two swing arms are arranged in a mirror image along the vertical axis of the box body, one end of the swing arm is hinged to the box body, and the two swing arms can swing relative to each other to a closed state suitable for blocking the brick inlet, and can also swing synchronously toward the two sides of the box body to avoid the open state of the brick inlet;

[0034] When the brick box moves along the rotary motion trajectory until it is flush with the feed conveyor and when it moves along the two-way conveyor, the two swing arms are switched from a closed state to an open state.

[0035] Exemplarily, two touch plates are provided on one side of the feed conveyor and the bidirectional conveyor close to the column, and the touch plates are aligned in pairs along the vertical direction, and two of the vertically aligned touch plates are aligned up and down with one of the swing arms of the brick box, and the other two vertically aligned touch plates are aligned up and down with the other swing arm of the brick box; wherein, when the brick box moves until the swing arm abuts against the touch plate, an open state is formed.

[0036] For example, the brick box also includes an elastic reset member and a limit pin; wherein, one end of the elastic reset member is connected to the box body, and the other end is connected to the swing arm, the swing arm remains in a closed state under the elastic force of the elastic reset member, and when the swing arm is in the closed state, the limit pin is against the swing arm.

[0037] In a possible implementation, the continuous brick feeding system of the masonry equipment includes two rotary conveying lines respectively located on both sides of the column, two feeding conveyors, and two bidirectional conveyors.

[0038] The beneficial effect of the continuous brick feeding system for masonry equipment provided by the present invention is that: compared with the prior art, the continuous brick feeding system for masonry equipment provided by the present invention sets a rotary conveyor line on the column to form a reciprocating rotary motion trajectory, so that each brick box on the rotary conveyor line circulates through the feed conveyor and the two-way conveyor in turn, and the bricks only need to be continuously placed on the feed conveyor, and the bricks can be sequentially entered into each brick box by the feed conveyor, and then when each brick box sequentially moves to the height of the two-way conveyor, the two-way conveyor receives the bricks in the brick box and The bricks are transported alternately to the two ends of the two-way conveyor in turn, and the masonry robot directly grabs bricks alternately from the two ends of the two-way conveyor for masonry operations. The brick delivery frequency can be synchronized with the masonry frequency, so as to achieve accurate brick delivery on demand and ensure that the brick delivery quantity matches the brick demand. It can not only avoid the stacking and accumulation of excess bricks on the masonry platform and occupying space, but also avoid the phenomenon of the masonry robot stopping and waiting due to untimely brick delivery. At the same time, the masonry robot only needs to grab materials at fixed points, without the need for additional destacking actions, thus improving the efficiency of masonry operations.

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0050] Please also read Figure 1 and Figure 7 , the continuous brick feeding system of masonry equipment provided by the present invention is now described. The continuous brick feeding system of masonry equipment includes a column 10, a rotary conveyor line 20, a feed conveyor 30, and a bidirectional conveyor 40; wherein the column 10 is used to be vertically arranged on a frame 50 and the bottom end supports the foundation or the bottom surface of the structure; the rotary conveyor line 20 is arranged on the column 10 and forms a rotary motion trajectory that reciprocates up and down, and the rotary conveyor line 20 is sequentially and spaced apart along the rotary motion trajectory with a plurality of brick boxes 200 suitable for accommodating brick units; the feed conveyor 30 is fixedly connected to the frame 50 in the horizontal direction, one end of the feed conveyor 30 extends out of the frame 50 and is used to receive bricks, and the other end is aligned with the rotary conveyor line 20 and is used to push bricks into the corresponding brick boxes 200 in sequence; the bidirectional conveyor 40 is connected to the column 10 and is spaced apart from the feed conveyor 30 in the upper and lower parts, and the bidirectional conveyor 40 is used to sequentially receive bricks in each brick box 200 and alternately transmit bricks to both ends thereof.

[0051] It should be explained that the column 10 is an essential installation component of the masonry equipment. In this embodiment, a rotary conveyor line 20 is added to the structure of the conventional column 10; specifically, the rotary conveyor line 20 can be a vertically arranged chain conveyor line or a belt conveyor line. Considering the load capacity and running stability, a chain conveyor line can be preferably used here; the feed conveyor 30 can be a conventional belt conveyor, or a roller conveyor, or a combined structure formed by connecting the two. Considering that the feed conveyor 30 needs to extend out of the frame 50 to receive bricks and has a long length, and the roller conveyor has a high cost and a large number of rollers, it is preferred to adopt a combined structure of a belt conveyor and a roller conveyor. The belt conveyor is used to receive the bricks and transport them to a position close to the column 10, and then the bricks are transported to a position aligned with the rotary conveyor line 20 by the roller conveyor. The gap between the rollers of the roller conveyor can facilitate the transfer of bricks into the brick box 200.

[0052] In this embodiment, the bidirectional conveyor 40 can be a belt conveyor or a roller conveyor. Considering the short length of the bidirectional conveyor 40, a roller conveyor can be preferably selected here, which can conveniently utilize the gap between the rollers to set up a structure for receiving bricks from the brick box 200 and placing the bricks on the rollers; the two ends of the bidirectional conveyor 40 respectively serve as fixed points for the masonry robot to grab bricks. When the bricks are transported to one end of the bidirectional conveyor 40, the masonry robot directly grabs the bricks from this end, and then the bidirectional conveyor 40 moves in the opposite direction, so that the next brick placed thereon is transported to the other end, and at the same time, the masonry robot grabs the bricks from the other end, and the alternating reciprocating motion is realized to achieve synchronous matching of the brick delivery and masonry processes.

[0053] Compared with the prior art, the continuous brick feeding system for masonry equipment provided in this embodiment is a system in which a rotary conveyor line 20 is arranged on the column 10 to form a reciprocating rotary motion trajectory, so that each brick box 200 on the rotary conveyor line 20 is circulated through the feed conveyor 30 and the bidirectional conveyor 40 in turn. It is only necessary to continuously place bricks on the feed conveyor 30, and the bricks can be sequentially entered into each brick box 200 by the feed conveyor 30. Then, when each brick box 200 sequentially moves to the height where the bidirectional conveyor 40 is located, the bidirectional conveyor 40 takes the bricks in the brick box 200 and delivers them to the feed conveyor 30. Bricks are picked up and conveyed alternately to the two ends of the two-way conveyor 40 in turn. The masonry robot directly grabs bricks alternately from the two ends of the two-way conveyor 40 for masonry operations. The brick delivery frequency can be synchronized with the masonry frequency, so as to achieve accurate brick delivery on demand and ensure that the brick delivery quantity matches the brick delivery demand. This can not only avoid the stacking and accumulation of excess bricks on the masonry platform to occupy space, but also avoid the phenomenon that the masonry robot stops waiting due to untimely brick delivery. At the same time, the masonry robot only needs to grab materials at fixed points, without the need for additional destacking actions, thereby improving the efficiency of masonry operations.

[0054] In some embodiments, see Figure 1 and Figure 2 The feed conveyor 30 includes a hanger 31, a belt conveyor part 32, a roller conveyor part 33, and a pushing assembly 34; wherein the hanger 31 is fixedly connected to the frame 50 and has a horizontally extending conveying channel; the belt conveyor part 32 is connected to the hanger 31 and is located in the conveying channel, one end of the belt conveyor part 32 extends out of the frame 50 to receive bricklaying; the roller conveyor part 33 is connected to the hanger 31 and docked with the other end of the belt conveyor part 32, and the roller conveyor part 33 is aligned with the rotary conveyor line 20; the pushing assembly 34 is arranged on the roller conveyor part 33 and is aligned with the rotary conveyor line 20, and is used to push bricklaying into the brick box 200 that travels to the same height as the roller conveyor part 33.

[0055] The frame 50 of the automatic masonry equipment is usually a gantry, and the hanger 31 is used here to suspend and fix the feed conveyor 30 on the crossbeam of the gantry to save space; the conveying channel in the middle of the frame 50 is used as the connection basis of the belt conveyor 32 and the roller conveyor 33, or a protective plate 311 is set on both sides of the belt conveyor 32 and the roller conveyor 33 on the frame 50 to form a conveying channel, so as to prevent bricks from falling during the conveying process; the belt conveyor 32 can be used to smoothly convey the received bricks to a position close to the column 10, and then the roller conveyor 33 conveys the bricks to a position aligned with the rotary conveyor line 20. The two conveying parts are driven independently, thereby ensuring The belt conveyor 32 continuously conveys bricks, while the roller conveyor 33 runs intermittently according to the walking frequency of the rotary conveyor line 20 (the distance between two brick boxes 200 is one step length, and the bricks are stopped once after each step length to receive the bricks). Of course, the roller conveyor can also run continuously, and at the same time, the bricks are blocked at a position aligned with the rotary conveyor line 20 by the limit plate 35, and then the bricks are pushed into the brick box 200 by the pushing assembly 34. During the pushing process, the sliding resistance of the bricks on the roller conveyor 33 is much smaller than that of the belt conveyor. Therefore, the structural method of using the pushing assembly 34 and the roller conveyor to push the bricks into the brick box 200 can avoid the bricks from tipping over and improve the stability of brick pushing.

[0056] Specifically, the belt conveyor section 32 may be a flat belt conveyor, and the roller conveyor section 33 may be a roller conveyor. In addition, each roller on the roller conveyor section 33 may be connected by a chain to ensure synchronization of movement, or each roller may be operated by an electric roller.

[0057] A transition bracket 36 is provided on one side of the roller conveyor 33 close to the rotary conveyor line 20. The height of the transition bracket 36 is flush with the height of the roller conveyor 33. Each brick box 200 on the rotary conveyor line 20 stops at a position flush with the height of the transition bracket 36 in turn, and the pushing assembly 34 pushes the bricks to the transition bracket 36 and then pushes them into the brick box 200. Here, the transition bracket 36 is used as a bridge between the roller conveyor 33 and the brick box 200, which can avoid the problem of bricks falling due to excessive gap between the roller conveyor 33 and the rotary conveyor line 20.

[0058] Optionally, the pushing assembly 34 includes a pushing cylinder 341 and a pushing plate 342 connected to the output end of the pushing cylinder 341. The pushing cylinder 341 moves until the bricks abutting against the limit plate 35 are aligned with the pushing plate 342. Then, the pushing cylinder 341 extends out and pushes the bricks through the transition bracket 36 into the brick box 200 aligned with the brick box 200 through the pushing plate 342. The structure is simple and reliable.

[0059] It should be noted that the bidirectional conveyor 40 can be a flat belt conveyor or a roller conveyor. Considering that a flat belt conveyor is inconvenient to receive bricks from the brick box 200 for laying bricks, a roller conveyor can be preferably used.

[0060] As a specific implementation of the bidirectional conveyor 40, please refer to Figures 3 to 6 The bidirectional conveyor 40 includes a mounting seat 41, a conveying frame 42, a material receiving assembly 43, and two jacking assemblies 44; wherein the mounting seat 41 is encircled by the column 10 and connected to the lifting work platform, and the mounting seat 41 is used to follow the lifting work platform to move up and down along the column 10; the conveying frame 42 is fixedly connected to the mounting seat 41, and the conveying frame 42 has a plurality of rollers 421 distributed in sequence from one end to the other end, and at least two rollers 421 located in the middle of the conveying frame 42 are aligned with the rotary conveyor line 20 to receive bricks, and each roller 421 is used to run synchronously in forward and reverse directions to convey bricks; the material receiving assembly 43 is arranged on the mounting seat 41 and aligned with the rotary conveyor line 20, and is used to receive bricks in each brick box 200 in sequence and place the bricks on the roller 421 in the middle of the conveying frame 42; the two jacking assemblies 44 are respectively arranged at both ends of the conveying frame 42, and the jacking assembly 44 is used to lift the bricks on the roller 421 that travels to the end of the conveying frame 42.

[0061] The mounting seat 41 is encircled by the column 10 and is raised and lowered synchronously with the lifting work platform, so that bricks can be transported to the corresponding position following the progress of masonry. The conveying frame 42 is fixed on the mounting seat 41 as the mounting base of the roller 421, and the bricks are transferred by the rotation movement of the roller 421. Specifically, each roller 421 can be connected in turn by a chain transmission to ensure the rotation synchronization. At the same time, the center distance of adjacent rollers 421 should ensure that the bricks can contact at least two rollers 421 at the same time, so as to ensure the stability of the bricklaying movement; the material receiving component 43 is preferably arranged in the middle position of the conveying frame 42, and the bricks in the brick box 200 that are flush with the height of the roller 421 are received by the material receiving component 43, and then the bricks are placed on the middle roller 421, so that the bricks are moved toward the conveying frame 4 as the roller 421 rotates. 2, when the bricklaying moves to the jacking assembly 44, the jacking assembly 44 lifts the bricklaying to a height separated from the roller 421, and then the roller 421 can rotate in the opposite direction, which can not only save the waiting time for grabbing materials, but also prevent the bricklaying from flowing back following the reverse rotation of the roller 421; the reversely rotating roller 421 transmits the next bricklaying to the jacking assembly 44 at the other end of the conveying frame 42 to be lifted up, and this is repeated repeatedly, and the masonry robot can alternately grab bricks from the two jacking assemblies 44 to carry out masonry operations, thereby realizing the synchronization of masonry and brick feeding, and because the mounting seat 41 is fixed to the lifting work platform, the spatial relative coordinates between the masonry robot fixed on the lifting work platform and the two jacking assemblies 44 are always fixed, thereby ensuring the accuracy of the masonry robot in grabbing bricks.

[0062] Specifically, see Figure 4 and Figure 5 In this embodiment, the optional structure of the material receiving component 43 is that the material receiving component 43 includes a slide 431, a material receiving frame 433, and a sliding driving member 434; the slide 431 is slidably connected to the mounting seat 41 along the axial direction of the roller 421, and a lifting member 432 is provided on the slide 431; the material receiving frame 433 is connected to the lifting output end of the lifting member 432, and a plurality of material receiving plates 4331 are distributed at intervals on the material receiving frame 433, and each material receiving plate 4331 is suitable for passing through the gap between adjacent rollers 421 and jointly supporting bricklaying; the sliding driving member 434 is provided with a plurality of material receiving plates 4331, and each material receiving plate 4331 is suitable for passing through the gap between adjacent rollers 421 and jointly supporting bricklaying; the sliding driving member 434 is provided with a plurality of material receiving plates 4331, and the plurality of material receiving plates 4331 are ... The driving member 434 is arranged on the mounting seat 41 and the output end is connected to the sliding seat 431; wherein, when the receiving rack 433 moves to the position directly below the brick box 200 which is flush with the height of the roller 421 under the drive of the sliding driving member 434, the lifting member 432 drives the receiving rack 433 to rise and hold up the bricks in the brick box 200, and when the receiving rack 433 moves to the position directly above the roller 421 under the drive of the sliding driving member 434, the lifting member 432 drives the receiving rack 433 to descend so that the bricks are placed on the roller 421.

[0063] Since the material receiving rack 433 needs to be inserted into the gap between adjacent rollers 421 and reciprocate between the conveying rack 42 and the rotary conveyor line 20, a avoidance opening is set on the side of the conveying rack 42 facing the rotary conveyor line 20. At the same time, in order to ensure the connection stability of each roller 421 aligned with the avoidance opening, a plurality of roller frames 423 are set at the position of the conveying rack 42 corresponding to the avoidance opening, and each roller frame 423 supports one of the rollers 421 aligned with the avoidance opening.

[0064] In addition, for the brick box 200, if Figure 8 As shown, a plurality of supporting rods 205 are arranged at the bottom, and the plurality of supporting rods 205 jointly support the brickwork, and each supporting rod 205 and each receiving plate 4331 of the receiving rack 433 are staggered and distributed with each other, and the top can be set to an open structure, and the sliding drive member 434 can be specifically a cylinder, a hydraulic cylinder or an electric push rod. When receiving the bricks in the brick box 200 that is flush with the height of the roller 421, the sliding drive member 434 pushes the slide seat 431 to move to drive the receiving rack 433 to reach the bottom of the brick box 200. , then the lifting member 432 lifts the receiving rack 433 upward, so that each receiving plate 4331 passes through the gap between adjacent support rods 205 to lift the bricks in the brick box 200, and then the sliding drive member 434 drives the slide 431 in the reverse direction to move, so that each receiving plate 4331 enters the gap between adjacent rollers 421. At this time, the bricks supported by the top of the receiving plate 4331 reach directly above the roller 421, and then the lifting member 432 drives the receiving rack 433 to descend and the bricks fall on the roller 421.

[0065] It should be noted that if Figure 4 As shown, both ends of the conveyor frame 42 are provided with limit stops 422, which are used to block the bricks running on the rollers 421 at both ends of the conveyor frame 42. By setting the limit stops 422, the bricks can be blocked just above the jacking assembly 44, which can prevent the bricks from falling due to over-running, and can ensure that the bricks can stay accurately above the jacking assembly 44, thereby ensuring the jacking stability of the bricks, and also improving the position accuracy of the bricks after jacking, so that the masonry robot can accurately grab the bricks.

[0066] On this basis, see Figure 6 The lifting assembly 44 includes a telescopic driving member 441 and a lifting frame 442. The telescopic driving member 441 is vertically arranged below the end of the conveying frame 42. The lifting frame 442 is connected to the output end of the telescopic driving member 441. A plurality of top plates 4421 are spaced apart on the lifting frame 442. Each top plate 4421 is suitable for passing through the gap between adjacent rollers 421 and supporting brickwork together. The lifting frame 442 is used to lift up the brickwork blocked on the side of the limit stop 422.

[0067] The telescopic drive member 441 can specifically be a cylinder, a hydraulic cylinder or an electric push rod. Before the bricklaying reaches the top of the lifting frame 442, the telescopic drive member 441 is in a retracted state. At this time, the top of each top plate 4421 is lower than the top height of the roller 421. When the bricklaying moves to abut against the limit stop 422 under the drive of the roller 421, the telescopic drive member 441 drives the lifting frame 442 to rise. At this time, each top plate 4421 passes through the gap between adjacent rollers 421 and rises above the roller 421, thereby lifting the bricklaying. The lifting process is stable and does not affect the forward and reverse switching movement of the roller 421, which can avoid the backflow of bricklaying, thereby saving the operation waiting time of the roller 421 when the masonry robot grabs the bricklaying, and improving the bricklaying transmission efficiency.

[0068] For example, see Figure 1 and Figure 7 The rotary conveyor line 20 includes a rotary drive member 21, a driving shaft 22, a driven shaft 23, and two transmission chains 24; wherein the rotary drive member 21 is fixedly connected to the column 10; the driving shaft 22 is rotatably connected to the column 10 and connected to the output end of the rotary drive member 21, and the driving shaft 22 is sleeved with two driving wheels 221 along its axial direction; the driven shaft 23 is connected to the column 10, and is located at the upper and lower ends of the column 10 respectively with the driving shaft 22, and two driven wheels 231 are rotatably connected to the driven shaft 23, and the two driven wheels 231 correspond to the two driving wheels 221 respectively; the two transmission chains 24 are respectively sleeved on the corresponding driving wheels 221 and driven wheels 231, and the two transmission chains 24 are commonly connected to each brick box 200.

[0069] The rotating driving member 21 can specifically be a motor, which drives the two driving wheels 221 on the driving shaft 22 to rotate synchronously through the rotating driving member 21, thereby synchronously driving the two driven wheels 231 on the driven shaft 23 to rotate through the two transmission chains 24, thereby ensuring the synchronization of the rotational motion of the two transmission chains 24, thereby improving the movement stability of each brick box 200 connected to the two transmission chains 24.

[0070] It should be noted that since the height of the column 10 depends on the height or depth of the structure, the required length of the transmission chain 24 is usually relatively large, and the transmission chain 24 is not suitable for applying a huge tensioning force. Therefore, in order to avoid the transmission chain 24 shaking and affecting the stability of the brick box 200, in this embodiment, chain guide grooves are provided on the column 10 at positions corresponding to each transmission chain 24, and the transmission chain 24 is embedded in the chain guide groove and slides up and down in the chain guide groove, thereby constraining the transmission chain 24 and improving the operating stability of the rotary conveyor line 20.

[0071] For some possible implementations, please combine Figure 7 and Figure 8 It is understood that the brick box 200 includes a box body 201 and two swing arms 202; the box body 201 is open on one side away from the column 10 to form a brick inlet; the two swing arms 202 are arranged along the vertical axis of the box body 201 in a mirror image, one end of the swing arm 202 is hinged to the box body 201, and the two swing arms 202 have a relative swing to a closed state suitable for blocking the brick inlet, and also have an open state of synchronously swinging toward the two sides of the box body 201 to avoid the brick inlet; wherein, when the brick box 200 moves along the rotary motion trajectory to be flush with the feed conveyor 30 and to be flush with the bidirectional conveyor 40, the two swing arms 202 switch from a closed state to an open state. The box body 201 with one side open can facilitate the horizontal entry and exit of bricks, and at the same time, the two swing arms 202 are used to block the bricks entering the box body 201, thereby preventing the bricks from falling and improving the safety of brick transmission.

[0072] It should be explained that, in the present embodiment, two touch plates 300 are provided on one side of the feed conveyor 30 and the bidirectional conveyor 40 close to the column 10, and the touch plates 300 are aligned in pairs along the vertical direction, and two of the vertically aligned touch plates 300 are aligned up and down with one of the swing arms 202 of the brick box 200, and the other two vertically aligned touch plates 300 are aligned up and down with the other swing arm 202 of the brick box 200; wherein, when the brick box 200 moves until the swing arm 202 abuts against the touch plate 300, an open state is formed.

[0073] When the brick box 200 moves to a position that is flush with or nearly flush with the height of the feed conveyor 30, the two swing arms 202 respectively contact the two touch plates 300 set at the height position, so that the two swing arms 202 swing toward the two sides of the box body 201 to avoid the brick inlet. After the bricks on the feed conveyor 30 are pushed into the box body 201, the two swing arms 202 lose the barrier of the touch plates 300 and return to the closed state after the rotary conveyor line 20 moves one step, thereby forming a barrier for the bricks. Similarly, when the brick box 2 When the box 200 moves to a position that is flush with or nearly flush with the height of the bidirectional conveyor 40, the two swing arms 202 respectively abut against the two touch plates 300 at the height position, so that the two swing arms 202 are in an open state again, thereby facilitating the brickwork to exit from the brick inlet and be transferred to the bidirectional conveyor 40; it can not only ensure that the brickwork can smoothly enter and exit the box body 201, but also use the swing arms 202 to block the brickwork. The structure is simple and ingenious, and the precise movement of the two swing arms 202 can be achieved without a control structure, which is beneficial to improving the operating stability.

[0074] On the basis of the above, see Figure 8 In some embodiments, the brick box 200 also includes an elastic reset member 203 and a limit pin 204; wherein, one end of the elastic reset member 203 is connected to the box body 201, and the other end is connected to the swing arm 202, and the swing arm 202 remains in a closed state under the elastic force of the elastic reset member 203, and when the swing arm 202 is in the closed state, the limit pin 204 is against the swing arm 202.

[0075] The elastic return member 203 can specifically be a spring or a torsion spring. By setting the elastic return member 203, a rebound force can be applied to the swing arm 202, thereby ensuring that the swing arm 202 can quickly swing back to a closed state abutting against the limit pin 204 after being separated from the touch plate 300, thereby avoiding the problem that the swing arm 202 cannot swing back in time to block the bricklaying, thereby ensuring the stability and safety of the bricklaying transmission.

[0076] For some possible implementations, see Figure 7 The continuous brick feeding system of the masonry equipment includes two rotary conveying lines 20 respectively located on both sides of the column 10, two feeding conveyors 30, and two bidirectional conveyors 40.

[0077] Normally, the masonry operation process is a collaborative operation of two or even more masonry robots. Therefore, rotary conveyor lines 20 are respectively set on both sides of the column 10. At the same time, two feeding conveyors 30 are respectively used to transport bricks to the two rotary conveyor lines 20, and two bidirectional conveyors 40 are respectively used to receive and transport bricks on the two rotary conveyor lines 20, thereby multiplying the efficiency of brick delivery and realizing accurate brick delivery to multiple masonry robots.

[0078] Specifically, since both ends of each bidirectional conveyor 40 can serve as target positions for the masonry robot to grab bricks at a fixed point, the two bidirectional conveyors 40 can form four target positions for grabbing bricks, so the synchronous masonry construction operations of four masonry robots can be satisfied at the same time, thereby improving work efficiency.

[0079] It should be understood that, depending on the type of bricks required for the structure, the two feed conveyors 30 can respectively receive bricks of the same type for transmission, or respectively receive bricks of different types for transmission, thereby improving the flexibility and adaptability of the brick transmission operation.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
