[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones, and other waste generated during demolition, construction, decoration, and repair activities in the construction industry. Currently, with the acceleration of urban construction, an increasing amount of construction waste is being generated, reaching tens of millions of tons annually. Landfill sites for construction waste amount to thousands of acres, making resource-based treatment of construction waste extremely important. Currently, the resource-based treatment of construction waste typically involves using existing screening machines to separate the crushed construction waste according to particle size. Existing screening machines include a screen box, a vibrating motor mounted on the screen box, and screens inside the screen box. However, the vibrating motor in these existing screening machines has high power and high energy consumption, which increases the cost of screening construction waste. Furthermore, the high vibration frequency of the vibrating motor causes severe vibration and significant noise in the entire screening machine, affecting the working environment of construction waste screening operations and easily causing discomfort to on-site workers. Summary of the Invention

[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a construction waste screening device to reduce the energy consumption and noise of the screening machine.

The size of the roller is adapted to the space formed between the inner wall of the first annular plate and the outer wall of the second annular plate so that the roller can move on the base plate along the space formed between the inner wall of the first annular plate and the outer wall of the second annular plate.

[0008] As a further limitation of this utility model, the vibration mechanism includes a plurality of vibration components disposed between the material guiding mechanism and the screening mechanism; the vibration components include a first mounting seat fixed to the top of the material guiding mechanism, a second mounting seat fixed to the bottom of the screening mechanism, a pipe hinged to the first mounting seat, a first limiting plate fixed to the outer wall of the pipe near one end of the first mounting seat, a rod with one end slidably connected inside the pipe and the other end hinged to the second mounting seat, a second limiting plate fixed to the outer wall of the rod near one end of the second mounting seat, and a spring sleeved on the outside of the pipe and the rod and located between the first limiting plate and the second limiting plate.

[0009] As another limitation of this utility model, the conveying mechanism is a belt conveyor with partitions.

[0010] As a further limitation of this utility model, the screening mechanism includes a screening frame and an inclined screen that is detachably connected to the screening frame.

[0011] As a further limitation of this utility model, the material guiding mechanism includes a material guiding frame and an inclined guide plate fixed on the material guiding frame.

The construction waste remaining after screening by the screening mechanism can be collected in the first collection mechanism, and the construction waste removed by the screening mechanism can be collected in the second collection mechanism. The present invention can realize the screening of construction waste to be screened and the classification and storage of the screened construction waste, which can effectively improve the convenience and practicality of the present invention.

[0016] (3) The conveying mechanism of this utility model adopts a belt conveyor with partitions. When in use, it can prevent the construction waste to be screened from falling from the conveying mechanism to the ground, which can effectively improve the stability and reliability of this utility model when in use.

[0017] (4) The bottom of the screening mechanism in this utility model is an inclined screen, which can facilitate the sifted construction waste to slide into the first collection mechanism. The bottom of the guiding mechanism is an inclined guide plate, which can facilitate the sifted construction waste to slide into the second collection mechanism.

[0018] In summary, this utility model has a reasonable structure, is easy to use, and is highly practical. It replaces the existing method of using a vibrating motor to provide vibration force to the screening mechanism via mechanical transmission, thus reducing energy loss and noise, and effectively lowering the cost of screening construction waste and reducing discomfort for on-site workers.

It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0034] Example 1: A construction waste screening device

[0035] like Figure 1 , Figure 2 As shown, this embodiment includes a base plate 1, a bracket fixed on the base plate 1, a turntable mechanism 5 rotatably mounted on the bracket via a drive mechanism 4, several vertical connecting mechanisms slidably connected to the bracket and capable of reciprocating in the vertical direction synchronously with the rotation of the turntable mechanism 5, a guiding mechanism 8 fixed on the top of the vertical connecting mechanisms, a screening mechanism 11 for screening construction waste located directly above the guiding mechanism 8, several dampers 9 fixed between the guiding mechanism 8 and the screening mechanism 11, and a series of dampers 9 located between the guiding mechanism 8 and the screening mechanism 11 that reciprocate in the vertical direction synchronously with the rotation of the turntable mechanism 5. The vibrating mechanism 10 provides vibration force to the screening mechanism 11 through the reciprocating motion of the receiving mechanism; the conveying mechanism 12, which is fixed on the base plate 1 via the conveyor frame and can transport the construction waste to be screened to the screening mechanism 11; the first collection mechanism 13, which is placed on the base plate 1 to collect the construction waste that has been screened by the screening mechanism 11; and the second collection mechanism 14, which is placed on the base plate 1 to collect the construction waste that has been screened by the screening mechanism 11. The base plate 1 is a rectangular plate, the driving mechanism 4 adopts an existing rotary motor, and the conveying mechanism 12 adopts a belt conveyor with partitions.

[0036] The support includes a support body 2 fixed to the base plate 1 and several support plates 3 fixed to the support body 2 and rotatably connected to the turntable mechanism 5. Specifically, in this embodiment, the support body 2 includes four vertical rods fixed to the base plate 1, a top plate fixed to the top of the four vertical rods, a horizontal rod fixed between each two vertical rods on the same side, a support plate 3 fixed on each horizontal rod, and the bottom of each support plate 3 fixed at a corresponding position on the top of the base plate 1.

[0037] like Figure 3 , Figure 4As shown, the turntable mechanism 5 includes a chassis 50 fixedly connected to the power output end of the drive mechanism 4, a first annular plate 51 fixedly disposed on the top periphery of the chassis 50, a second annular plate 52 fixedly disposed on the top of the chassis 50 and located inside the first annular plate 51, and four guide blocks 54 fixedly disposed on the top of the chassis 50 between the first annular plate 51 and the second annular plate 52 for guiding several vertical connecting mechanisms to reciprocate synchronously in the vertical direction. 4. Guide blocks 54 are evenly distributed on the base plate 1 between the first annular plate 51 and the second annular plate 52. Each guide block 54 includes an upsloping block, a downsloping block, and a transition block with an arc-shaped top surface fixed between the upsloping block and the downsloping block. The upsloping block, the transition block, and the downsloping block are integrally formed. When the roller 6 in the vertical connecting mechanism passes through the guide block 54, the roller 6 moves upward and then downward under the action of the guide block 54, and the roller 6 can fit tightly against the top surface of the guide block 54. An annular groove 53 is provided at the bottom of the chassis 50. Several support plates 3 are inserted into the annular groove 53, and the portion of the support plates 3 inserted into the annular groove 53 is adapted to the annular groove 53 so that the base plate 1 can rotate on the support plates 3.

[0038] This embodiment includes four vertical connecting mechanisms. Each vertical connecting mechanism includes a sliding rod 7 slidably connected to the top plate of the support body 2, and rollers 6 rotatably mounted on the bottom of the sliding rod 7 via roller brackets, positioned on the top of the base plate 1 between the inner wall of the first annular plate 51 and the outer wall of the second annular plate 52. The size of the rollers 6 is adapted to the space formed between the inner wall of the first annular plate 51 and the outer wall of the second annular plate 52, allowing the rollers 6 to move along the space between the inner wall of the first annular plate 51 and the outer wall of the second annular plate 52 on the base plate 1. It is important to emphasize that when the chassis 50 rotates, the four rollers 6 always pass synchronously through the four guide blocks 54, enabling the four rollers 6 to move upwards and downwards simultaneously.

[0039] like Figure 5 As shown, the vibration mechanism 10 includes a plurality of vibration components disposed between the material guiding mechanism 8 and the screening mechanism 11. The vibration components include a first mounting base 100 fixed to the top of the material guiding mechanism 8, a second mounting base 101 fixed to the bottom of the screening mechanism 11, a pipe 102 hinged to the first mounting base 100, a first limiting plate 103 fixed to the outer wall of the pipe 102 near one end of the first mounting base 100, a rod 104 with one end slidably connected inside the pipe 102 and the other end hinged to the second mounting base 101, a second limiting plate 105 fixed to the outer wall of the rod 104 near one end of the second mounting base 101, and a spring 106 sleeved on the outside of the pipe 102 and the rod 104 and located between the first limiting plate 103 and the second limiting plate 105.

[0040] The screening mechanism 11 includes a screening frame and an inclined screen detachably connected to the screening frame. The material guiding mechanism 8 includes a material guiding frame and an inclined guide plate fixed to the material guiding frame. It should be noted that, as defined herein, the end of the screening mechanism 11 furthest from the conveying mechanism 12 is the discharge end of the screening mechanism 11, and the end of the material guiding mechanism 8 closest to the conveying mechanism 12 is the discharge end of the material guiding mechanism 8. In this embodiment, the side of the inclined screen closest to the conveying mechanism 12 is higher than the side of the inclined screen furthest from the conveying mechanism 12, and the side of the inclined guide plate furthest from the conveying mechanism 12 is higher than the side of the inclined guide plate closest to the conveying mechanism 12.

[0041] The first collection mechanism 13 includes a first box with an opening at the top, such as Figure 6 As shown, the first box includes a first rectangular plate 130, a first U-shaped plate 131 fixed on the first rectangular plate 130, a first sliding door plate 132 slidably connected to the opening of the first U-shaped plate 131 for closing the opening of the first U-shaped plate 131, and a first box support 134 provided on the first U-shaped plate 131. A first handle 133 is fixed on the first sliding door plate 132. The first box support 134 is an existing structure that can ensure that the first box is stably supported on the base plate 1. The opening at the top of the first box is located below the discharge end in the screening frame so that the construction waste remaining after being screened by the screening mechanism 11 can enter the first box from the inclined screen.

[0042] The second collection mechanism 14 includes a second box with a top opening. The second box includes a second rectangular plate, a second U-shaped plate fixed on the second rectangular plate, a second sliding door plate slidably connected to the opening of the second U-shaped plate for closing the opening of the second U-shaped plate, and a second box support plate provided on the second U-shaped plate. A second handle is fixed on the second sliding door plate. The second box support plate is an existing structure that ensures that the second box is stably supported on the base plate 1. The opening at the top of the second box is located below the discharge end in the guide frame so that the construction waste screened by the screening mechanism 11 can enter the second box from the inclined guide plate.

[0043] The working principle of this embodiment is as follows: the construction waste is accurately conveyed to the screening mechanism 11 by the conveying mechanism 12; the chassis 50 is driven to rotate by the motor. At this time, the chassis 50 can rotate stably under the action of several support plates 3. When the chassis 50 rotates, the guide block 54 on the chassis 50 can make the roller 6 move up and down. The up and down movement of the roller 6 will cause the sliding rod 7 to move up and down. The up and down movement of the sliding rod 7 can drive the material guiding mechanism 8 to move up and down. The up and down movement of the material guiding mechanism 8 will drive the vibration mechanism 10 to vibrate. This vibration will cause the screening mechanism 11 to vibrate through transmission. The vibration of the screening mechanism 11 can screen the construction waste. The construction waste screened out by the screening mechanism 11 falls into the material guiding mechanism 8 and falls into the second collection mechanism 14 under the guidance of the material guiding mechanism 8. The construction waste not screened out by the screening mechanism 11 falls into the first collection mechanism 13.

[0044] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
