Description

Technical Field

[0001] This utility model relates to the field of recycled concrete recycling technology, and in particular to a recycled concrete recycling device. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing, cleaning, and grading waste concrete blocks, mixing them with aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel, and then adding cement, water, etc. Concrete is a major building material during construction, and construction sites usually have concrete waste. Waste concrete usually needs to be recycled, which requires the use of recycling equipment.

[0003] An existing recycled concrete waste recycling device (publication number: CN222152197U) has at least the following drawbacks: Although the device sorts the crushed waste through multiple layers of filter plates, it is difficult to flexibly adjust the inclination angle of the filter plates, making it difficult to adapt to the screening requirements of waste with different particle sizes, moisture content, and densities. At the same time, the filter plates are fixed structures and lack vibration function, which makes it easy for materials to accumulate or clog the screen holes during the screening process. Especially when processing concrete waste with high moisture content or uneven particle distribution, the screening efficiency and accuracy may drop significantly, resulting in poor recycling effect of the device. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a recycled concrete recycling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A recycled concrete recycling device includes a processing box with a feed hole on its top surface. A double-roll crusher is fixed to the top surface of the processing box, and the position of the double-roll crusher corresponds to the feed hole. The processing box has a sorting structure inside, which includes three screen plates rotatably disposed inside the processing box. The three screen plates are arranged vertically. Three sliding holes are opened on one side of the processing box, and fixed shafts are slidably disposed inside each of the three sliding holes. The three fixed shafts are respectively fixed to one side of the three screen plates. A lead screw is rotatably disposed on one side of the processing box, and three movable plates are threadedly connected to the outer circular wall of the lead screw. The top surfaces of the three movable plates are respectively attached to the outer circular walls of the three fixed shafts.

[0007] As a further embodiment of this utility model, a first motor is fixed on the top surface of the processing box, and the output end of the first motor is fixed to the top end of the lead screw. A mounting hole is provided on the top surface of the movable plate, and a movable shaft is slidably inserted into the mounting hole. The top end of the movable shaft is in contact with the outer circular wall of the fixed shaft. Two snap-fit ​​shafts are fixed on the outer circular wall of the movable shaft, and a spring is wound around the outer circular wall of the movable shaft. The two ends of the spring abut against the inner wall of the mounting hole and the snap-fit ​​shaft, respectively. A second motor is fixed on the bottom surface of the movable plate, and a cam is fixed on the output end of the second motor. The outer circular wall of the cam is in contact with the bottom end of the movable shaft.

[0008] As a further embodiment of this utility model, discharge holes are provided on both sides of the processing box, and the two discharge holes correspond to the positions of the two sieve plates located above. The bottom surface of the processing box is open.

[0009] As a further embodiment of this utility model, a guide plate is fixed inside the feed hole, and the guide plate is inclined.

[0010] As a further embodiment of this utility model, the inner wall of the processing box is provided with three sliding grooves, each corresponding to a sliding hole, and the three sieve plates are slidably arranged within the three sliding grooves.

[0011] As a further embodiment of this utility model, support rods are fixed at the four corners of the bottom surface of the processing box, and the bottom diameter of the support rods is larger than the top diameter.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The recycling device, through the setting of the sorting structure, uses a double-roll crusher to crush concrete waste. The crushed debris enters the processing box through the feed hole and is screened by three screen plates. The first motor drives the lead screw to rotate, causing the three movable plates to rise. The rising movable plates drive one side of the three screen plates to tilt up through the fixed shaft, thereby adjusting the tilt angle of the three screen plates.

[0014] The second motor drives the cam to rotate. The cam, through the action of the movable shaft, spring and snap-fit ​​shaft, reciprocates against the fixed shaft, causing the screen plate to vibrate. This vibrating screens the waste material. In this way, the screening requirements of different waste materials are met, and the accumulation and clogging of the screen holes during the screening process are avoided, thereby improving the screening efficiency and recycling effect of the device.

[0024] In this embodiment, a first motor is fixed to the top surface of the processing box 1, and the output end of the first motor is fixed to the top end of the lead screw 204.

A second motor is fixed to the bottom surface of the movable plate 205, and a cam 210 is fixed to the output end of the second motor. The outer circular wall of the cam 210 is in contact with the bottom end of the movable shaft 207. Through the sorting structure, workers feed concrete waste into the roller crusher 3 for crushing. The crushed material... The waste enters the processing box 1 through the feed hole 2 and is screened by three screen plates 201. When the screen plates 201 are screening, the user can start the first motor to drive the lead screw 204 to rotate, causing the three movable plates 205 to rise. The rising movable plates 205 drive one side of the three screen plates 201 to tilt up through the fixed shaft 203, thereby adjusting the inclination angle of the three screen plates 201. At the same time, the user starts the second motor, which drives the cam 210 to rotate. When the cam 210 rotates, it continuously pushes the movable shaft 207. Under the action of the spring 209 and the snap-fit ​​shaft 208, the movable shaft 207 pushes the fixed shaft 203 back and forth, thereby causing the screen plates 201 to vibrate. This vibrating screening of waste materials is achieved by the above methods, which meet the screening requirements of different waste materials, avoids the accumulation and clogging of screen holes during the screening process, and improves the screening efficiency and recycling effect of the device.

[0025] In this embodiment, discharge holes 301 are provided on both sides of the processing box 1. The two discharge holes 301 correspond to the positions of the two screen plates 201 located above.

[0027] In this embodiment, the inner wall of the processing box 1 is provided with three sliding grooves 5, which correspond to the positions of three sliding holes 202 respectively. The three sieve plates 201 are slidably arranged inside the three sliding grooves 5 respectively.

[0029] Working Principle: During operation, the operator feeds concrete waste into the roller crusher 3 for crushing. The crushed debris enters the processing box 1 through the feed hole 2 and is screened by three screen plates 201. While the screen plates 201 are screening, the user can start the first motor to drive the lead screw 204 to rotate, causing the three movable plates 205 to rise. The rising movable plates 205, through the fixed shaft 203, cause one side of the three screen plates 201 to tilt, thereby adjusting the inclination angle of the three screen plates 201. At the same time, the user starts the second motor, which drives the cam 210 to rotate. When the cam 210 rotates... The movable shaft 207 is continuously pushed, and under the action of the spring 209 and the snap-fit ​​shaft 208, the movable shaft 207 reciprocates against the fixed shaft 203, thereby causing the screen plate 201 to vibrate, thus performing vibratory screening of the waste material. The materials of different particle sizes screened by the three screen plates 201 are discharged from the two discharge holes 301 and the bottom surface of the processing box 1, respectively.
