Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling and treatment technology, and in particular to a construction waste screening device. Background Technology

[0002] Construction waste includes not only large pieces of gravel, steel bars, and wood, but also a significant proportion of construction waste mud. This waste mud contains a certain proportion of usable components such as fine sand and gravel particles. After proper screening and processing, these fine particles can be used for backfilling, brick making, etc., which can reduce the mining of natural sand and gravel resources, realize resource reuse, and conform to the concept of sustainable development.

[0003] Currently, the common practice for recycling construction waste involves manually or using transportation equipment to transfer the waste from storage sites to large, fixed screening devices. After screening, the separated construction waste and construction residue are then transferred to their respective storage sites. The efficiency of this entire process needs improvement. Furthermore, large, fixed screening devices are generally difficult to move, so the storage sites for construction waste must be determined based on the location of these devices, which imposes significant limitations on available space. Utility Model Content

[0004] In view of this, the present invention proposes a construction waste sludge screening device, the purpose of which is to improve the recycling efficiency of construction waste sludge to at least a certain extent.

[0006] A construction waste sludge screening device, comprising:

[0007] beam;

[0008] Two symmetrically arranged clamps on the crossbeam are hinged to the crossbeam, and the bottom of the clamps is provided with multiple sieve holes;

[0009] A first actuator, the first actuator being used to drive the two clamps away from or towards each other;

[0010] A baffle, wherein the baffle is disposed at the bottom of the clamp;

[0011] The second driver is used to drive the baffle to move so that the baffle blocks the sieve holes on the hopper, or opens the sieve holes on the hopper.

[0012] As a further optional solution, the clamp includes a bottom plate, side plates located on both sides of the bottom plate, and a rear plate located between the two side plates;

[0013] A cavity is formed between the bottom plate, the two side plates and the rear plate, and openings are provided on the opposite sides of the two clamps;

[0017] As a further alternative, the first actuator is a hydraulic cylinder, and two first actuators are provided, with the two first actuators respectively located on both sides of the two clamps;

[0018] The two side plates of the clamp are provided with mounting seats on their outer sides. One end of the first driver is hinged to the mounting seat on one clamp, and the other end of the first driver is hinged to the mounting seat on the other clamp.

[0019] As a further optional solution, the baffle is hinged to one end of the clamp and extends into a pull plate, the pull plate being provided with a pull rod;

[0020] The rear plate is provided with a hinge seat;

[0025] Compared with the prior art, the construction waste sludge screening device of this application has at least the following advantages:

[0026] This construction waste screening device features two clamps hinged to a crossbeam and equipped with screen holes at the bottom. A first actuator moves the two clamps closer together or further apart, allowing construction waste to be directly clamped into the clamps during collection. Compared to traditional methods that require transferring construction waste to large, fixed screening devices, this device reduces material transfer steps and improves screening efficiency. Furthermore, its flexible structure allows it to be moved according to the location of construction waste generation, adapting to the operational needs of different sites.

[0027] The baffle at the bottom of the hopper works in conjunction with the second actuator to block the screen holes and prevent material leakage during construction waste collection. Once moved to the appropriate position, the second actuator drives the baffle to open the screen holes, allowing construction waste to be screened out directly, while large pieces of gravel, steel bars, and other construction debris remain inside the hopper. This simultaneous collection and screening of construction waste further optimizes the processing flow. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0041] refer to Figure 1-3 An embodiment of this utility model illustrates a construction waste sludge screening device, including a crossbeam 1, two clamps 2, a first driver 3, a baffle 4, and a second driver 5. The two clamps 2 are symmetrically arranged on the crossbeam 1, and the clamps 2 are hinged to the crossbeam 1. The bottom of the clamps 2 is provided with a plurality of screen holes 211. The first driver 3 is used to drive the two clamps 2 to move away from each other or to move closer to each other. The baffle 4 is disposed at the bottom of the clamps 2. The second driver 5 is used to drive the baffle 4 to move so that the baffle 4 blocks the screen holes 211 on the clamps 2, or opens the screen holes 211 on the clamps 2.

[0042] Specifically, the first driver 3 drives the two clamps 2 to move away from or closer to each other, thereby enabling the two clamps 2 to close or separate, and thus enabling the clamping and discharge of materials; when the baffle 4 blocks the screen hole 211, the material can be stably clamped in the two clamps 2; and when the baffle 4 no longer blocks the screen hole 211, that is, when the screen hole 211 is open, the material in the two clamps 2 can be screened.

[0043] In one application example, the construction waste screening device can be mounted on a mobile device, such as the robotic arm of an excavator. This allows the device to be moved directly to the construction waste generation point at a construction site. Construction waste is loaded into the two hoppers 2, at which point a baffle 4 covers the screen holes 211 of the hoppers 2. The device then moves to the construction waste dumping point, for example, using a transport vehicle. The transport vehicle parks directly near the construction waste generation point, and the excavator can move the screening device simply by rotating its robotic arm. Above the transport vehicle; then the second drive 5 drives the baffle 4 to move. The movement of the baffle 4 includes sliding, translation, and flipping, so that the baffle 4 leaves the position of the cover screen hole 211, exposing the screen hole 211. The construction waste in the hopper 2 can be screened out through the screen hole 211 and fall into the transport vehicle, while large pieces of gravel, steel bars, wood and other construction waste remain in the hopper 2. After the construction waste is screened out, the construction waste screening device is moved to the waste dumping point, and the first drive 3 is used to open the two hoppers 2 to discharge large pieces of gravel, steel bars, wood and other construction waste.

[0044] Thus, this construction waste screening device, by setting up two clamps 2 hinged to the crossbeam 1 and equipped with screen holes 211 at the bottom, and cooperating with the first drive 3 to move the two clamps 2 away from each other or closer together, can directly clamp construction waste into the clamps 2 during collection. Compared with the traditional method of transferring construction waste to a large fixed screening device, this reduces the material transfer links and greatly improves the efficiency of the overall screening process. At the same time, the device has a flexible structure and can be moved flexibly according to the location of construction waste generation to adapt to the operational needs of different sites. The baffle 4 set at the bottom of the clamp 2 and the cooperation of the second drive 5 ensure that when collecting construction waste, the baffle 4 can block the screen holes 211 to prevent material leakage; when moved to a suitable position, the second drive 5 drives the baffle 4 to move, opening the screen holes 211, allowing construction waste to be screened directly out through the screen holes 211, while large pieces of gravel, steel bars and other construction debris remain in the clamp 2. This allows the collection and screening of construction waste to be carried out simultaneously, further optimizing the processing flow.

[0045] In some embodiments, such as Figure 1-3 As shown, the clamp 2 includes a bottom plate 21, side plates 22 located on both sides of the bottom plate 21, and a rear plate 23 located between the two side plates 22; a cavity (not marked in the figure) is formed between the bottom plate 21, the two side plates 22 and the rear plate 23, and openings (not marked in the figure) are respectively provided on the opposite sides of the two clamps 2; the upper end of the side plate 22 is hinged to the crossbeam 1.

[0046] Thus, when the two clamps 2 are closed, there is sufficient space between them to hold construction waste. Before the baffle 4 below the base plate 21 is opened, the construction waste remains stably between the two clamps 2.

[0047] In some embodiments, such as Figure 3 As shown, the surface contour of the baffle 4 matches the surface contour of the base plate 21; the baffle 4 is hinged to the clamp 2, and the second driver 5 is used to drive the baffle 4 to rotate relative to the base plate 21.

[0048] The base plate 21 can be a flat plate, an arc plate, or other structures, and the baffle 4 should match it so that it can be attached to the bottom of the base plate 21. In this embodiment, the sieve holes 211 on the base plate 21 can be exposed by rotating the baffle 4.

[0049] In some embodiments, to stably achieve the closing and separation of the two clamps 2, such as Figure 1-3 As shown, the first actuator 3 is a hydraulic cylinder, and there are two first actuators 3, which are respectively arranged on both sides of the two clamping buckets 2; the two side plates 22 of the clamping bucket 2 are provided with mounting seats 222 on the outer side, one end of the first actuator 3 is hinged to the mounting seat 222 on one clamping bucket 2, and the other end of the first actuator 3 is hinged to the mounting seat 222 on the other clamping bucket 2.

[0050] In some embodiments, to facilitate the opening of the baffle 4, such as Figure 3 As shown, the baffle 4 is hinged to one end of the clamp 2, extending out as a pull plate 41, and the pull plate 41 is provided with a pull rod 42; the rear plate 23 is provided with a hinge seat 231; the second driver 5 is a hydraulic cylinder, one end of the second driver 5 is hinged to the pull rod 42 on the baffle 4, and the other end is hinged to the hinge seat 231 on the rear plate 23.

[0051] The second driver 5 is located behind the rear plate 23, which can prevent the second driver 5 from affecting the two clamps 2 for clamping construction waste.

[0052] In some embodiments, the upper end of the side plate 22 is hinged to the crossbeam 1 around a horizontal pivot (not marked in the figure), and the upper end of the side plate 22 is provided with a transmission gear 221, which is coaxially arranged with the horizontal pivot; the transmission gear 221 of the side plate 22 on one clamp 2 meshes with the transmission gear 221 of the side plate 22 on another clamp 2.

[0053] The transmission gear 221 connects the two clamping buckets 2, resulting in higher synchronization of the two clamping buckets 2 and more stable clamping action.

[0054] In some embodiments, such as Figure 1 As shown, a flange connection 11 is provided at the top center of the crossbeam 1. Thus, the crossbeam 1 of the construction waste screening device can be connected to a mobile device, such as the robotic arm of an excavator, through the flange connection 11.

[0055] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
