DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] The embodiment of the present application discloses a conveyor belt for separating construction waste after crushing.

[0028] Reference Figure 1-2 The conveyor belt for separating construction waste after crushing includes a frame 1, a screening plate 2, a transmission belt 3 and a driving mechanism. The frame 1 is formed by fixing rods and plates to each other as a frame foundation, and the screening plate 2 is a rectangular long plate and there are multiple screening plates 2. The multiple screening plates 2 are arranged side by side and the sides are close to or in contact with each other. A plurality of sieve holes are provided on the screening plate 2, and the plurality of sieve holes are evenly distributed on the corresponding screening plates 2. The cross-sectional areas of the sieve holes on different screening plates 2 are different, so as to sort out waste materials of different sizes (such as crushed concrete) for use as raw materials for laying different foundations.

[0029] The transmission belt 3 is divided into a material dividing belt and a material feeding belt, the material dividing belt is located at the top, and the material feeding belt is located at the bottom. There is a material feeding belt under each sub-screen plate 2, and the upper belt surface of the material feeding belt extends along the length direction of the corresponding sub-screen plate 2. The driving mechanism is used to drive each transmission belt 3 to rotate.

[0030] It can be understood that each transmission belt 3 is in an annular shape.

[0031] The dividing belt is located above the dividing screen plate 2 and the extension direction of the lower belt surface is transversely perpendicular to the arrangement direction of the dividing screen plate 2. A plurality of movable plates 4 are installed on the outer belt surface of the feeding belt. The length of the movable plates 4 extends along the width of the feeding belt. The plurality of movable plates 4 are evenly distributed along the length direction of the feeding belt. The movable plate 4 located below the feeding belt extends toward the dividing screen plate 2 away from one end of the feeding belt.

[0032] During use: first send the crushed construction waste to the platform on the side of the feeding belt, then manual sorting can be carried out, and then the staff uses tools (such as: a push plate driven by a hydraulic cylinder, etc.) to push the waste little by little to the area of ​​the sub-screen plate 2 with smaller sieve holes; during the process, the driving mechanism drives the sub-screen belt to rotate and drives the movable plate 4 to rotate, and the movable plate 4 moves from the small sieve hole area to the large sieve hole area under the feeding belt, then the movable plate 4 can drive the construction waste to move little by little, and during the movement, waste of different sizes falls from sieve holes of different sizes onto the corresponding feeding belt, and at the same time, the staff can sort some materials again from the spread out waste; the waste falling on the feeding belt is deducted and sent away.

[0033] According to the above content, it can be seen that the present application can not only transport construction waste, but also separate the construction waste according to size, so as to help the staff to better carry out the recycling of construction waste.

[0034] Reference Figure 2 The present application also includes a partition 5, the length of which extends along the length of the sub-screen plate 2, and the height of the partition 5 is adapted to the distance between the sub-screen plate 2 and the upper belt surface of the feed belt. There are multiple partitions 5 and they are respectively located between each sub-screen plate 2.

[0035] Take three sub-screen plates 2 as an example: there is a partition plate 5 between two adjacent sub-screen plates 2; the partition plate 5 can be used to prevent the construction waste from colliding, jumping, and flipping during the falling process and moving to the outside of the corresponding feeding belt.

[0036] Reference Figure 2 In order to meet the needs of sorting different grades, a chute 51 extending along the length direction is provided on the upper part of the partition 5, and the side of the screening plate 2 is plugged into the chute 51, and the end of the chute 51 is open. When it is necessary to sort out waste materials of different sizes, the staff can pull out the original screening plate 2 and insert the new screening plate 2 from the end of the chute.

[0037] Reference Figure 2 The driving mechanism includes a lower linkage module 6, which is used to drive several feeding belts to rotate at the same time. The lower linkage module 6 includes a single roller 61, a gear set 62 and a motor 63, wherein the rotating shaft at the end of the single roller 61 is rotatably connected to the frame 1 through a bearing seat, and the single roller 61 is located on the inner side of the feeding belt and contacts the inner belt surface of the feeding belt; there are at least two or more single rollers 61 on the inner side of a feeding belt, which has formed a circulating transmission structure.

[0038] The gear set 62 includes a gear 1 on the end shaft of each single roller 61, and a gear 2 that rotates on the frame and makes the adjacent gear 1 rotate synchronously; or, includes a configured gear box, the input and output shafts of the gear box are connected to the shaft of the single roller 61 on the corresponding side. The setting of the gear set 62 allows the staff to adjust the gear speed ratio according to the needs to change the speed of each feeding belt; for example: the speed of the feeding belt under the small sieve hole is lower than the speed of the feeding belt under the large sieve hole. The motor 1 63 is installed on the frame 1 and the output shaft is connected to a single roller 1 61 through a coupling.

[0039] Reference Figure 2 The driving mechanism also includes an upper unit 7, which includes a single roller 2 71 and a motor 2 72; the rotating shaft at the end of the single roller 2 71 is rotatably connected to the frame 1 through a bearing seat, the single roller 2 71 is located on the inner side of the dividing belt and contacts the inner belt surface of the dividing belt, and there are at least two or more single rollers 2 on the inner side of a dividing belt; the motor 2 72 is installed on the frame 1 and is connected to a single roller 2 71 through a coupling.

[0040] In one embodiment of the present application, the movable plate 4 is hinged to the hinge seat on the feeding belt, and the hinged rotation surface is vertical. The end of the movable plate 4 away from the feeding belt is bent, and the inner angle formed by the bend is tilted downward below the feeding belt. In order to prevent the movable plate 4 from being unable to spread and drive the waste, a stop block 41 is provided on the movable plate 4. The stop block 41 is located on the back of the movable plate 4 and prevents the movable plate 4 from continuing to rotate upward when the movable plate 4 forms an angle of about 10° with the lower belt surface of the material distribution belt.

[0041] The hinge of the movable plate 4 can reduce the damage caused by the excessive height of the waste being driven and stuck between the lower end of the movable plate 4 and the sub-screening plate 2, and the movable plate 4 continues to move. The movable plate 4 can be made of alloy, and the counterweight block is preferentially welded near the bending part.

[0042] Reference Figure 3 In one embodiment of the present application, a striking mechanism 8 is installed on the side wall of the partition 5, and the striking mechanism 8 includes a lifting rod 81, an end block 82 and a cylinder 83, wherein the lifting rod 81 is vertical, the end block 82 is located at the upper end of the lifting rod 81 and below the sub-screen plate 2, and the rod end of the cylinder 83 fixes the lifting rod 81.

[0043] During use, the cylinder 83 is controlled to repeatedly expand and contract, driving the end block 82 to repeatedly collide with the sub-screen plate 2 to generate vibration, so as to help waste pass through the sieve hole. The end block 82 can be made of wood and wrapped with cloth to reduce the probability of the sub-screen plate 2 being deformed by collision.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
