Description

Technical Field

[0001] The present invention relates to the technical field of construction waste classification, and in particular to a conveying device for regenerating and making sand from lightweight construction waste based on visual measurement. Background Art

[0002] With the acceleration of urbanization, the amount of construction waste generated is becoming increasingly large, among which the resource utilization of lightweight construction waste has become a research hotspot in the field of environmental protection and resources. Recycling lightweight construction waste into sand can effectively reduce the pressure on the environment caused by garbage accumulation. In the production process of recycling lightweight construction waste into sand, the conveying device is a vital link, and its performance directly affects the subsequent processing quality and efficiency. At present, in the process of conveying lightweight construction waste, traditional conveying devices generally have the problem of uneven distribution of construction waste on the conveyor belt, which makes it difficult for subsequent visual measurement mechanisms to obtain accurate and comprehensive data, resulting in large measurement errors and an inability to provide reliable data support for the recycled sand making process, which in turn affects the quality of recycled sand and the precise regulation of production process parameters.

[0003] The patent with announcement number CN221521381U discloses a construction waste sorting component, which uses a servo motor to drive the conveyor belt to rotate and thus move the construction waste, and uses the baffle plate of the leveling mechanism on the conveyor belt to level the construction waste. The baffle plate can move up and down using a buffer spring, and the lower end of the baffle plate is designed to be inclined. During use, it is not easy for the conveyor belt to be unable to drive it to move due to large construction waste, resulting in blockage at the leveling mechanism. As a result, the construction waste can be leveled on the conveyor belt after passing through the leveling mechanism.

[0004] Although the above scheme uses a leveling mechanism to flatten higher construction waste, the construction waste on the conveyor belt may be more in the middle and less on both sides or less in the middle and more on both sides before passing through the leveling mechanism. After these construction wastes pass through the leveling mechanism, some conveyor belts may have no construction waste or less construction waste, so that the construction waste is not evenly leveled on the conveyor belt, which is not conducive to the visual measurement mechanism to distinguish the construction waste. Therefore, it is necessary to solve the problem that the construction waste cannot be evenly leveled on the conveyor belt. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention is provided with a gathering mechanism, a dispersing mechanism and a thickness control mechanism. The two first guiding structures in the gathering mechanism can gather the messy construction waste to the middle according to the different distribution states of the construction waste on the conveyor belt, such as more on both sides and less in the middle or less on both sides and more in the middle. The V-shaped plate of the dispersing mechanism cooperates with the two second guiding structures to guide the construction waste to move to both sides of the conveyor belt.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 11As shown: A conveying device for lightweight construction waste recycled sand making based on visual measurement, comprising a conveyor belt 1 and a visual measurement mechanism 2 for visually distinguishing construction waste, and also comprising a paving mechanism, a gathering mechanism 4, a dispersing mechanism 5 and a thickness control mechanism 6; the paving mechanism comprises a frame 3 connected to both sides of the conveyor belt 1; the gathering mechanism 4 is mounted at one end of the frame 3, the gathering mechanism 4 comprises two first mounting plates 41, the lower ends of the two first mounting plates 41 are each provided with a first guide structure 42, the two first guide structures 42 are used to guide the construction waste to gather toward the middle of the conveyor belt 1; the dispersing mechanism 5 is mounted at the other end of the frame 3, the dispersing mechanism 5 comprises a V-shaped plate 51 for guiding the construction waste to disperse toward both sides of the conveyor belt 1, and both sides of the V-shaped plate 51 are provided with a second guide structure 52; the thickness control mechanism 6 comprises a second mounting plate 61 for mounting the V-shaped plate 51 and two third mounting plates 62 for mounting the two second guide structures 52, and the upper end of the second mounting plate 61 is provided with a lifting drive assembly 63.

[0034] When the light construction waste is put onto the conveyor belt 1, it immediately enters the paving mechanism and begins to be paved. First, the construction waste comes to the gathering mechanism 4, and the first guiding structure 42 at the lower end of the two first mounting plates 41 installed at the front end of the frame 3 plays a role. If the light construction waste is distributed on the conveyor belt 1 with more on both sides and less in the middle, the first guiding structure 42 will guide the construction waste on both sides to the middle of the conveyor belt 1. If there is less on both sides and more in the middle, the first guiding structure 42 will also regularize the construction waste and gather the construction waste toward the middle, so as to concentrate the light construction waste randomly distributed on the conveyor belt 1 in the middle area. Then, the gathered light construction waste continues to move forward with the conveyor belt 1 and contacts the V-shaped plate 51 in the dispersion mechanism 5 at the rear end of the frame 3. The light construction waste between the lower end of the V-shaped plate 51 and the conveyor belt 1 is directly moved due to the continuous operation of the conveyor belt 1. The construction waste that contacts the V-shaped plate 51 will move toward both sides of the conveyor belt 1 along the V-shaped plate 51 under the guidance of the V-shaped plate 51. In this process, the second guiding structures 52 set on both sides of the V-shaped plate 51 will assist the construction waste to move more smoothly to both sides, further ensuring that the construction waste can be evenly dispersed over the entire width of the conveyor belt 1. Finally, the evenly dispersed lightweight construction waste is transported to the visual measurement mechanism 2 under the drive of the conveyor belt 1. The visual measurement mechanism 2 is able to perform accurate visual identification and measurement on it, providing accurate data support for the subsequent regeneration sand making process. Through the coordinated work of the gathering mechanism 4 and the dispersing mechanism 5, the problem of uneven distribution of lightweight construction waste on the conveyor belt 1 is effectively solved. Regardless of whether there is more on both sides and less in the middle or less on both sides and more in the middle during the initial delivery, the lightweight construction waste can be evenly spread on the conveyor belt 1.

[0035] Reference Figure 3 and Figure 4 As shown: the first guiding structure 42 includes a first conveyor belt 421, and a plurality of first hooks 422 are arranged at equal intervals on the first conveyor belt 421; the second guiding structure 52 includes a first conveyor belt 421, and a plurality of second hooks 522 are arranged at equal intervals on the second conveyor belt 521; the first conveyor belt 421 and the second conveyor belt 521 guide the construction waste in opposite directions.

[0036] When the conveyor belt 1 transports the construction waste to the gathering mechanism 4 at the front end of the frame 3, the first guide structure 42 installed at the lower end of the two first mounting plates 41 starts to operate, and the first conveyor belts 421 in the two first guide structures 42, and the multiple first hooks 422 distributed at equal intervals thereon play a role. The first conveyor belt 421 drives the first hook 422 to apply a force toward the middle of the conveyor belt 1 to the construction waste located between the two first guide structures 42. The first hook 422 can effectively pull the construction waste, so that the construction waste is gradually gathered toward the middle of the conveyor belt 1. The gathered construction waste continues to move backward with the conveyor belt 1 until it meets the dispersion mechanism 5 at the rear end of the frame 3. The V-shaped plate 51 contacts the V-shaped plate 51. At this time, the second guiding structures 52 on both sides of the V-shaped plate 51 intervene to work. On the second conveyor belt 521 of the second guiding structure 52, the second hooks 522 arranged at equal intervals are opposite to the guiding direction of the first conveyor belt 421. The second hooks 522 apply a force toward the side of the conveyor belt 1 to the construction waste in contact with the V-shaped plate 51. Under the dual action of the traction of the second hooks 522 and the guidance of the V-shaped plate 51, the construction waste is dispersed to both sides of the conveyor belt 1, and finally evenly covers the entire surface of the conveyor belt 1, so that the densely stacked construction waste can be effectively gathered and dispersed, which greatly improves the uniformity of the distribution of construction waste on the conveyor belt 1.

[0037] Reference Figure 4 and Figure 5 As shown: the gathering mechanism 4 also includes two transition structures 43 respectively installed on the two first mounting plates 41, the transition structure 43 includes a guide plate 431, a movable plate 432 and a tension spring 433; one side of the guide plate 431 is connected to the first conveyor belt 421; the movable plate 432 is rotatably connected to the other side of the guide plate 431; the two ends of the tension spring 433 are connected to the guide plate 431 and the movable plate 432.

[0038] If no transition structure 43 is provided between the two first guide structures 42 and the V-shaped plate 51, after the construction waste is blocked by the V-shaped plate 51, some of the construction waste cannot enter the channel between the second guide structure 52 and the V-shaped plate 51. Therefore, a transition structure 43 is provided, and the gathered construction waste is introduced into the transition structure 43 installed on the first mounting plate 41 under the action of the first conveyor belt 421. One side of the guide plate 431 of the transition structure 43 is docked with the first conveyor belt 421, and the construction waste enters the area between the two guide plates 431 along the first conveyor belt 421. At this time, the movable plate 432 arranged on the other side of the guide plate 431 is kept in contact with the second conveyor belt 521 under the action of the tension spring 433. The construction waste passes through the channel between the two movable plates 432 and smoothly enters the channel between the second guide structure 52 and the V-shaped plate 51. When the construction waste continues to move and When the V-shaped plate 51 contacts, the second guide structures 52 on both sides of the V-shaped plate 51 start to work. On the second conveyor belt 521 of the second guide structure 52, the second hook claws 522 arranged at equal intervals exert a force toward the side of the conveyor belt 1 on the construction waste in contact with the V-shaped plate 51. During the operation of the second conveyor belt 521, the second hook claws 522 thereon will intermittently contact the movable plate 432. When the second hook claws 522 contact the movable plate 432, they will push the movable plate 432 to separate it from the second conveyor belt 521. After the second hook claws 522 are separated from the movable plate 432, the tension spring 433 quickly pulls the movable plate 432 to reset, ensuring that the movable plate 432 is re-contacted with the second conveyor belt 521. Through the cooperation between the guide plate 431 and the movable plate 432, and the resetting effect of the tension spring 433 on the movable plate 432, it is ensured that the construction waste can smoothly transition from the gathering stage to the dispersion stage.

[0039] Reference Figure 4 and Figure 6 As shown: a first cleaning claw 4311 is provided on the side where the guide plate 431 is docked with the first conveyor belt 421. The first cleaning claw 4311 is parallel to 422, and the first cleaning claw 4311 and the first hook claw 422 are staggered with each other. The first cleaning claw 4311 is used to clean the light construction waste attached to the first hook claw 422.

[0040] When the first hook claw 422 on the first conveyor belt 421 applies a force toward the middle of the conveyor belt 1 on the construction waste, some construction waste may be stuck in the first hook claw 422. When the first hook claw 422 applies a force on the construction waste again, the effect of the first hook claw 422 is reduced. Therefore, a first cleaning claw 4311 is provided. As the first conveyor belt 421 continues to operate, when the first hook claw 422 passes the first cleaning claw 4311 provided on the side where the guide plate 431 and the first conveyor belt 421 are connected, the first cleaning claw 4311 will clean the first hook claw 422. The first cleaning claw 4311 removes the construction waste stuck in the first hook claw 422, so that the first hook claw 422 is restored to a clean state, ensuring that when a force is applied to the construction waste again in the future, a good grasping and gathering effect can be maintained, thereby avoiding the reduction in the grasping effect of the first hook claw 422 due to residual construction waste.

[0041] Reference Figure 6 As shown: a limiting plate 434 is provided on the other side of the guide plate 431, one end of the limiting plate 434 is fixedly connected to the guide plate 431, and the other end of the limiting plate 434 extends into the movable range of the movable plate 432, and the limiting plate 434 is used to limit the movable range of the movable plate 432, and the side of the limiting plate 434 in contact with the movable plate 432 is attached with a flexible material that reduces the collision force between the movable plate 432 and the limiting plate 434.

[0042] After the second hook 522 contacts the movable plate 432, the movable plate 432 will rotate around the connection between it and the guide plate 431. At this time, the movable plate 432 may rotate excessively, making it impossible for the tension spring 433 to pull the movable plate 432 back to its original position. Therefore, a limit plate 434 is provided on the other side of the guide plate 431. When the second conveyor belt 521 of the second guide structure 52 is working, the second hook 522 applies a force toward the side of the conveyor belt 1 to the construction waste. The second hook 522 will intermittently contact the movable plate 432, and the second hook 522 pushes the movable plate 432 to rotate around the connection between it and the guide plate 431, so that it is in contact with the second conveyor belt 521. The conveyor belt 521 separates to provide space for the movement of the second hook 522. At this time, the limit plate 434, which is fixedly connected to the guide plate 431 and has the other end extending to the movable plate 432, comes into play to limit the rotation angle of the movable plate 432 and prevent the movable plate 432 from excessive rotation. When the second hook 522 separates from the movable plate 432, the tension spring 433 pulls the movable plate 432 to reset. Due to the presence of the limit plate 434, the movable plate 432 can return to the initial position of abutting the second conveyor belt 521 under the action of the tension spring 433, thereby effectively avoiding the problem that the movable plate 432 cannot be reset due to excessive rotation during the contact process with the second hook 522.

[0043] Reference Figure 4 and Figure 7As shown: the dispersion mechanism 5 includes a channel width adjustment structure 53 arranged on the second mounting plate 61, the channel width adjustment structure 53 is connected to the V-shaped plate 51, and the channel width adjustment structure 53 is used to control the channel width between the two sides of the V-shaped plate 51 and the two second guide structures 52.

[0044] The channel width adjustment structure 53 includes a linear moving component 531 and a moving block 532. The linear moving component 531 is fixedly mounted on the second mounting plate 61. The moving block 532 is transmission-connected to the linear moving component 531. The linear moving component 531 is used to drive the moving block 532 to move along the conveying direction of the conveyor belt 1. The moving block 532 is fixedly connected to the V-shaped plate 51.

[0045] When the particles of construction waste are small and the distance between the second guide structure 52 and the V-shaped plate 51 is large, the guiding effect of the second guide structure 52 on the construction waste is small. Therefore, a channel width adjustment structure 53 is set. The linear moving component 531 in the channel width adjustment structure 53 can adopt a screw-actuated driving member. The linear moving component 531 fixedly mounted on the second mounting plate 61 drives the moving block 532, driving the V-shaped plate 51 close to the second guide structure 52, reducing the channel width, so that the construction waste between the second conveyor belt 521 and the V-shaped plate 51 is squeezed, increasing the friction between the construction waste and the second conveyor belt 521, which is beneficial for the second conveyor belt 521 to drive the construction waste to move, thereby ensuring that construction waste of different sizes can be guided by the second guide structure 52.

[0046] Reference Figure 7 and Figure 8 As shown: the dispersion mechanism 5 also includes two blocking structures 54, which are respectively arranged at both ends of the V-shaped plate 51, and the blocking structure 54 abuts against one end of the second guide structure 52 at the edge of the conveyor belt 1. The blocking structure 54 is used to prevent the construction waste from moving out of the conveyor belt 1 under the drive of the second guide structure 52.

[0047] The blocking structure 54 includes a blocking plate 541, an adaptive support assembly 542 for applying a force to the blocking plate 541 toward the second conveyor belt 521, and a second cleaning claw 543. The side of the blocking plate 541 is in contact with the second conveyor belt 521, the adaptive support assembly 542 is installed on the V-shaped plate 51, and the second cleaning claw 543 is installed on the blocking plate 541, and the second cleaning claw 543 and the second hook claw 522 are staggered with each other.

[0048] When the second conveyor belt 521 drives the construction waste to move toward both sides of the conveyor belt 1, if the moving range of the construction waste is not restricted, the construction waste may move out of the conveyor belt 1 under the action of the second conveyor belt 521. Therefore, two blocking structures 54 are set, and the second hook 522 on the second conveyor belt 521 drives the construction waste to move toward both sides of the conveyor belt 1. At this time, the blocking structures 54 at both ends of the V-shaped plate 51 play a role, and the adaptive support component 542 installed on the V-shaped plate 51 continuously applies a force to the blocking plate 541 toward the second conveyor belt 521, so that the side of the blocking plate 541 always keeps in contact with the second conveyor belt 521. The adaptive support component 542 can adopt a guiding function When the second conveyor belt 521 is in operation, the second cleaning claw 543 which is staggered with the second hook 522 and is installed on the blocking plate 541 starts to work. When the second hook 522 passes the second cleaning claw 543, the second cleaning claw 543 removes the construction waste stuck in the second hook 522, ensuring that the second hook 522 always maintains a good grasping and guiding effect, thereby effectively preventing the construction waste from sliding off the two sides of the conveyor belt 1 under the action of the second conveyor belt 521, and ensuring that all construction waste can be evenly distributed on the conveyor belt 1 and smoothly transported to the visual measurement mechanism 2.

[0049] Reference Figure 1 and Figure 9 As shown, the gathering mechanism 4 further includes an opening and closing structure 44 , which is disposed on the frame 3 , and is used to control the distance between the two first guide structures 42 .

[0050] The opening and closing structure 44 includes a bidirectional moving component 441 and two connecting arms 442. The bidirectional moving component 441 is set on the frame 3. The two connecting arms 442 are respectively connected to the two first mounting plates 41. The bidirectional moving component 441 is used to drive the two connecting arms 442 to move in a direction perpendicular to the conveyor belt 1.

[0051] If the distance between the two first guide structures 42 is fixed, when the construction waste is stuck between the two first guide structures 42, it is not convenient to clear the passage between the two first guide structures 42. Therefore, an opening and closing structure 44 is set. When the construction waste is stuck between the two first guide structures 42, the opening and closing structure 44 is started, and the two-way moving component 441 drives the two connecting arms 442 to move in a direction perpendicular to the conveyor belt 1, so that the two first guide structures 42 move away from each other, and the distance between the two first guide structures 42 is expanded. At this time, the clamping force on both sides of the stuck construction waste is reduced, so that the friction force of this part of the construction waste is reduced, which makes it easier for the conveyor belt 1 to drive this part of the construction waste to move. After this part of the construction waste is flattened, the two-way moving component 441 drives the connecting arm 442 again to restore the two first guide structures 42 to the initial set distance, and continue to gather the construction waste, thereby effectively solving the problem of blockage that is difficult to handle under fixed spacing, greatly improving the flexibility of the conveying device to cope with different working conditions, and ensuring the continuous and stable operation of the equipment.

[0052] Reference Figure 10 As shown, a plurality of lifting guide structures 64 are provided on the third mounting plate 62 , and both ends of the lifting guide structure 64 are connected to the first mounting plate 41 and the third mounting plate 62 respectively. The lifting guide structure 64 is used to guide the third mounting plate 62 to rise and fall.

[0053] Specifically, the lifting guide structure 64 includes a bracket plate 641 and a first guide rod 642, one end of the bracket plate 641 is fixedly connected to the first mounting plate 41, the first guide rod 642 is slidingly connected to the bracket plate 641, and one end of the first guide rod 642 is fixedly connected to the third mounting plate 62.

[0054] When the first mounting plate 41 is driven by the bidirectional moving component 441 of the opening and closing structure 44 and moves in a direction perpendicular to the conveyor belt 1, the bracket plate 641 fixed on the first mounting plate 41 moves accordingly, and the first guide rod 642 connected thereto drives the third mounting plate 62 to move synchronously, ensuring that the relative position relationship between the second guide structure 52 and the first guide structure 42 is stable, which is conducive to the stable operation of the transition structure 43. When the height of the second guide structure 52 needs to be adjusted, the lifting drive component 63 drives the second mounting plate 61 to move, thereby causing the V-shaped plate 51 and the third mounting plate 62 connected to the second mounting plate 61 to generate a lifting demand. At this time, the first guide rod 642 slides along the bracket plate 641, guiding the third mounting plate 62 to rise and fall smoothly, thereby effectively avoiding the third mounting plate 62 from shaking, offsetting and other instabilities during horizontal movement and lifting movement, and ensuring that the second guide structure 52 is always in a suitable working position.

[0055] Reference Figure 11As shown: a plurality of lifting synchronization structures 65 are also provided on the third mounting plate 62, and the two ends of the lifting synchronization structure 65 are respectively connected to the second mounting plate 61 and the third mounting plate 62. The lifting synchronization structure 65 is used to keep the second mounting plate 61 and the third mounting plate 62 rising and falling synchronously.

[0056] The lifting synchronization structure 65 includes a second guide rod 651 and a slider 652. One end of the second guide rod 651 is fixedly connected to the second mounting plate 61, and the axis of the second guide rod 651 is parallel to the driving direction of the bidirectional moving component 441. The slider 652 is slidingly connected to the second guide rod 651, and the slider 652 is connected to the third mounting plate 62.

[0057] When the first mounting plate 41 is driven by the bidirectional moving component 441 of the opening and closing structure 44 and moves in a direction perpendicular to the conveyor belt 1, the bracket plate 641 of the lifting guide structure 64 drives the first guide rod 642, and then drives the third mounting plate 62 to move synchronously. At the same time, the second guide rod 651 and the slider 652 of the lifting synchronization structure 65 cooperate to further ensure that the third mounting plate 62 moves stably in the horizontal direction, and ensure that the relative position relationship between the second guide structure 52 and the first guide structure 42 and other components is stable. When the lifting drive component 63 drives the second mounting plate 61 During movement, the V-shaped plate 51 connected to the second mounting plate 61 generates a lifting demand. At the same time, the second guide rod 651 fixed on the second mounting plate 61 rises and falls accordingly. The second guide rod 651 drives the third mounting plate 62 to rise and fall synchronously through the slider 652, ensuring that the second conveyor belt 521 of the second guide structure 52 maintains a suitable working position relationship with the V-shaped plate 51 and the construction waste. The lifting synchronization structure 65 ensures that the second mounting plate 61 and the third mounting plate 62 always remain synchronized during the lifting process through the cooperation between the second guide rod 651 and the slider 652.
