Technical Field

[0001] The present application relates to the technical field of waste classification, and in particular to a construction waste sorting system. Background Art

[0002] Construction waste refers to the waste such as slag, concrete, abandoned materials, wood, etc. generated during the construction or demolition of various buildings, structures, pipe networks, etc. In the prior art, when processing construction waste, it is first necessary to crush the bulk construction waste uniformly, and then sort them into garbage piles of different materials, and then screen the construction waste of different sizes through a screening device, and then recycle them.

[0003] The existing utility model patent with announcement number CN212018915U discloses a construction and decoration waste resource disposal system, including: a screening and classification mechanism, a crushing mechanism and an intelligent sorting robot; the screening and classification mechanism and the intelligent sorting robot are suitable for classifying construction and decoration waste; the crushing mechanism is suitable for crushing large pieces of waste and classified high-clean aggregates. This construction and decoration waste resource disposal system classifies construction and decoration waste through a screening and classification mechanism, and finally crushes the classified high-clean aggregates through a crushing mechanism, thereby improving the sorting efficiency of construction and decoration waste.

[0004] The existing construction waste sorting system uses boxes or carts to receive the materials at the discharge position. If the capacity is full and is not removed in time, the garbage will fall out. Personnel need to pay attention to whether the box or cart is full in real time, which is inconvenient. Utility Model Content

[0005] The present application provides a construction waste sorting system that can automatically replace a cart to receive the garbage, thereby preventing the garbage from falling out after being full. It does not require real-time attention from personnel and is relatively convenient.

[0006] The construction waste sorting system provided in the present application includes a screening device, which has multiple discharge positions, and also includes multiple conveying devices, mobile vehicles, and mobile devices. The input ends of the multiple conveying devices correspond one-to-one to the multiple discharge positions. The mobile device includes a conveyor belt three embedded in the ground and a support plate fixed to the ground surface. The top surface of the support plate is in sliding contact with the bottom surface of the upper belt surface of the conveyor belt three. The middle part of the support plate has a hole and is equipped with a floor scale. The floor scale is located directly below the output end of the conveying device. The mobile vehicle is provided with multiple and arranged on the conveyor belt three. The belt surface of the conveyor belt three is fixed with multiple limit strips along its length direction. The bottom of the mobile vehicle is rotatably connected to a roller, and the limit strip is used to limit the roller.

[0007] Through the above technical solution, at least two mobile carts are pre-placed on each conveyor belt three. After the construction waste screened by the screening device is output from each discharge position, it falls into the mobile cart through the conveying device. As the amount of garbage in the mobile cart increases, the overall weight of the mobile cart also increases. The scale weighs the weight. When the weight detected by the scale is greater than the set value, the conveyor belt three is controlled to move the distance of a mobile cart, so that the mobile cart that is full or nearly full moves forward, and the empty mobile cart at the rear replaces the mobile cart to receive the construction waste falling from above. Through this construction waste sorting system, the mobile cart can be automatically replaced to receive the garbage, avoiding the situation where the garbage falls out after being full. The personnel only need to move the full mobile cart in front before the new mobile cart is full, and then push the empty mobile cart in the rear. The time interval is relatively long, so there is no need for personnel to pay attention in real time, which is more convenient.

[0008] Preferably, the conveying device comprises a horizontally extending conveyor belt 1 and a slantingly upwardly extending conveyor belt 2, wherein the input end of the conveyor belt 2 is connected below the output end of the conveyor belt 1.

[0009] Through the above technical solution, the function of conveyor belt one is to move the garbage out from the bottom of the screening device; the function of conveyor belt two is to lift the garbage output by conveyor belt one to a high place, so as to facilitate the collection of construction waste by large-volume containers.

[0010] Preferably, a plurality of limit plates are fixed on the belt surface of the second conveyor belt along its length direction.

[0011] Through the above technical solution, when the garbage is lifted, the limit plate prevents the garbage from falling downwards.

[0012] Preferably, the cross section of the limiting strip is triangular, and both side walls of the limiting strip are inclined surfaces tilted upward.

[0013] Through the above technical solution, personnel can push the mobile vehicle with force to roll the roller over the limit bar through the inclined surface of the limit bar, so as to facilitate manual adjustment of the position of the mobile vehicle.

[0014] Preferably, the interior of the limiting strip is hollow, and the inner bottom wall of the limiting strip and the conveyor belt are fixed by rivets.

[0015] According to the technical solution, the limit strip is fixed to the conveyor belt 3 by rivets. When the conveyor belt 3 is bent and deformed, it is less likely to break compared with an integrally fixed form.

[0016] Preferably, a flared guide cylinder is fixed on the top of the moving vehicle, and adjacent moving vehicles are in contact with each other through the guide cylinder.

[0017] Through the above technical solution, the diameter of the guide cylinder for receiving garbage is enlarged, the garbage is not easy to fall out, and the garbage can be prevented from leaking out from the gap between adjacent mobile vehicles.

[0018] Preferably, a handle is fixed to the side wall of the mobile vehicle.

[0019] Through the above technical solution, the mobile vehicle can be pushed and pulled by the handle.

[0020] Preferably, the handles are disposed on the four walls of the mobile vehicle, and the handles are combined and formed into a ring.

[0021] Through the above technical solution, the handle arranged in a ring shape is convenient for people to pull, and people can pull the mobile vehicle in any direction, which is easy to use.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through this construction waste sorting system, the mobile vehicle can be automatically replaced to receive the garbage, so as to avoid the garbage falling out after being full. The staff only needs to move the full mobile vehicle in front before the new mobile vehicle is full, and then push the empty mobile vehicle in the back. It is more convenient without the need for staff to pay attention in real time;

[0024] 2. By setting up a flared guide cylinder, garbage can be prevented from leaking out from the gap between adjacent mobile vehicles;

[0025] 3. By setting up an inclined conveyor belt 2, the garbage can be lifted to a high place, making it easier for large-volume containers to collect construction waste. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 1 This embodiment discloses a construction waste sorting system, including a screening device 1, the screening device 1 has multiple discharge positions 11, and also includes multiple conveying devices 2, mobile vehicles 3, and mobile devices 4. The input ends of the multiple conveying devices 2 correspond to the multiple discharge positions 11 one by one. The screening device 1 is any form in the prior art, which screens the construction waste through a screen plate or a screen mesh, and the screened waste of different sizes is discharged from the multiple discharge positions 11 respectively. The conveying device 2, the mobile vehicle 3, and the mobile device 4 are used as a set, and each set corresponds to each discharge position 11.

[0034] Reference Figure 1 and Figure 2 The conveying device 2 includes a horizontally extending conveyor belt 1 21 and an obliquely upwardly extending conveyor belt 2 22. The input end of the conveyor belt 1 21 is connected to the corresponding discharge position 11, and the input end of the conveyor belt 22 is connected to the lower part of the output end of the conveyor belt 1 21. The conveyor belt 1 21 and the conveyor belt 2 22 are both conventional conveyor belt structures driven by motors. The discharge position 11 of the screening device 1 is generally at the bottom of the device, with a relatively low height and a shielded top. The function of the conveyor belt 1 21 is to remove the garbage from the bottom of the screening device 1 and to increase the discharge height by a small amount; the function of the conveyor belt 22 is to lift the garbage output by the conveyor belt 1 21 to a high place, so as to facilitate the collection of construction waste by large-volume containers. A plurality of limit plates 23 are fixed on the belt surface of the conveyor belt 22 along its length direction. The limit plates 23 are horizontally arranged on the conveyor belt 22. The limit plates 23 are used to prevent the garbage from falling downward when the garbage is lifted.

[0035] Reference Figure 3 and Figure 4The mobile device 4 includes a conveyor belt 3 41 embedded in the ground and a support plate 42 fixed to the ground. The conveyor belt 3 41 is driven by a servo motor. The top surface of the support plate 42 is in sliding contact with the bottom surface of the upper belt surface of the conveyor belt 3 41. The support plate 42 supports the mobile vehicle 3 above. A hole is opened in the middle of the support plate 42 and a floor scale 43 is installed. The floor scale 43 is located directly below the output end of the conveyor device 2. The top surface of the floor scale 43 is flush with the top surface of the support plate 42. The length of the floor scale 43 can only weigh the weight of one mobile vehicle 3. The signal output end of the floor scale 43 is electrically connected to the controller, and the controller controls whether the conveyor belt 3 41 moves.

[0036] Reference Figure 3 , the mobile car 3 is provided with a plurality of and arranged on the conveyor belt 3 41, and the bottom of the mobile car 3 is rotatably connected with rollers 31, and the rollers 31 are preferably two ordinary wheels on one side and two universal wheels on the other side. A guide cylinder 32 in a flared shape is fixed on the top of the mobile car 3, and adjacent mobile cars 3 are in contact through the guide cylinder 32. Such an arrangement can prevent garbage from leaking out of the gap between adjacent mobile cars 3. A handle 33 is fixed on the side wall of the mobile car 3, and the handle 33 is arranged on all four walls of the mobile car 3, and the handle 33 is combined and surrounded in a ring. The handle 33 arranged in a ring shape is convenient for personnel to pull, and personnel can pull the mobile car 3 in any direction, which is easy to use, and the handle 33 is located in the projection of the guide cylinder 32 along the vertical direction, so the handles 33 of adjacent mobile cars 3 will not collide.

[0037] Reference Figure 3 and Figure 4 The belt surface of the conveyor belt 3 41 is fixed with a plurality of limit strips 44 along its length direction, and the limit strips 44 are used to limit the roller 31. The cross section of the limit strip 44 is a triangle, preferably an isosceles triangle, and both side walls of the limit strip 44 are inclined surfaces inclined upward. The limit strip 44 can prevent the roller 31 from rolling spontaneously, and when the limit strip 44 moves with the belt surface of the conveyor belt 3 41, the limit strip 44 can push the roller 31 to move through the inclined surface, thereby driving the mobile vehicle 3 to move. A person can push the mobile vehicle 3 with force to roll the roller 31 over the limit strip 44 through the inclined surface of the limit strip 44.

[0038] Reference Figure 5 The inner part of the limiting strip 44 is hollow, and the inner bottom wall of the limiting strip 44 and the conveyor belt 3 41 are fixed by rivets 45. A plurality of rivets 45 are arranged at intervals along the length direction of the limiting strip 44. The limiting strip 44 is fixed to the conveyor belt 3 41 by the rivets 45, and the bottom edge of the limiting strip 44 can move relative to the conveyor belt 3 41. Since the size of the rivets 45 is small, when the conveyor belt 3 41 is bent and deformed, it is not easy to cause the problem of breaking or the reduction of the flexibility of the conveyor belt compared with the form of integral fixing.

[0039] The implementation principle of a construction waste sorting system of the present application is as follows: at least two mobile vehicles 3 are pre-placed on each conveyor belt three 41, and the construction waste screened by the screening device 1 is transported from each discharge position 11 to the conveyor belt one 21, and then after being lifted by the conveyor belt two 22, it falls from the output end of the conveyor belt two 22 into the mobile vehicle 3 directly below. As the amount of garbage in the mobile vehicle 3 increases, the overall weight of the mobile vehicle 3 also increases, and the scale 43 weighs the weight, and the signal is sent to the controller. When the weight detected by the scale 43 is greater than the set value, the controller controls the conveyor belt three 41 to move the distance of a mobile vehicle 3, so that the mobile vehicle 3 that is full or nearly full moves forward, and the empty mobile vehicle 3 at the rear replaces the mobile vehicle 3 to receive the construction waste dropped from above.

[0040] Through this construction waste sorting system, the mobile vehicle 3 can be automatically replaced to receive the garbage, avoiding the garbage falling out after being full. The staff only needs to move the full mobile vehicle 3 in front before the new mobile vehicle 3 is full, and then push the empty mobile vehicle 3 in the back. The time interval is relatively long, so there is no need for staff to pay attention in real time, which is more convenient.

[0041] 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.
