[0032] When construction waste is in the final recycling stage, some of the small pieces of metal waste materials in it are also subjected to final treatment at the same time; if the small pieces of metal waste materials mentioned above can be recycled and sorted before the final recycling stage, it can avoid the waste of resources and provide the beneficial effect of renewable energy recovery for the overall recycling process of material waste; therefore, please refer to Figure 1-4 , the utility model provides a technical solution: a metal product screening device for construction engineering, comprising a frame 1, wherein a detection mechanism 3 and a selection mechanism 4 are arranged inside the frame 1;

[0035] In some specific embodiments of this application, please refer to Figure 1 Or 2: A conveyor belt 2 is installed inside the frame 1, and the conveyor belt 2 is used to transport construction waste and is inspected by the inspection mechanism 3 and sorted and screened by the sorting mechanism 4;

[0036] In this solution, in specific applications, the staff will lay the construction waste crushed by the crusher (which is now in small pieces) on the conveyor belt 2 to ensure uniform laying without overlapping;

[0038] Through the above-mentioned driving mode, the first power member 302 of the detection mechanism 3 drives the first ball screw 303 to rotate, generates the first linear degree of freedom, and then drives the lifting frame 304 to perform lifting and lowering adjustment, so as to provide a preliminary basis for the focusing function of the detection components under different detection environments on the material areas laid by the conveyor belts 2 of different specifications, or the staff can adjust the other detection coefficients to lift and lower;

[0039] In this solution, the detection component includes a CCD industrial vision camera 305 and a metal detector 306;

[0040] The CCD industrial vision camera 305 is used to distinguish the metal or rusty metal parts in the current material pile, and detect them through the metal detector 306 to determine whether they are metal materials;

[0041] For details, please refer to Figure 3 In the figure, there are more than one metal detectors 306 and they are arranged in an array to expand the detection options and their range and to achieve point-to-point detection.

[0042] In some specific embodiments of this application, please refer to Figure 4 The picking mechanism 4 includes a second frame 401, a second power member 402 installed on the second frame 401, a second ball screw 403 driven by the second power member 402, and a third frame 404 fixedly matched with a movable nut of the second ball screw 403; the third frame 404 is slidably matched with the second frame 401, and a picking component is installed on the third frame 404.

[0043] In this solution, the second power member 402 drives the second ball screw 403 and generates a second linear degree of freedom on the third frame 404 to adjust and control the basic detection space area of ​​the picking component; wherein the picking component is a mechanical arm type component, and its picking range is controlled based on the above second linear degree of freedom, and the specific selection is made by the staff;

[0044] In this solution, the picking assembly includes a fourth frame 405 and a hinge arm 407 driven by a third power member 406; the two ends of the hinge arm 407 respectively cooperate with the body and the output shaft of the third power member 406, and the fourth frame 405 is fixedly matched with the inner wall of a hinge arm 407; the third power member 406 at the very end is equipped with a metal adsorption part for picking and screening metal objects.

[0045] At the same time, the third power member 406 and the hinge arm 407 are Figure 4 As shown, the third power member 406 - hinge arm 407 - third power member 406 - hinge arm 407 ... type of matching relationship is presented, which further enables the third power member 406 to drive the hinge arm 407 and the components connected to the rear thereof to adjust the angle and position.

[0046] It should be pointed out that in this specific embodiment, the output shaft axes of each third power member 406 do not overlap with each other, thereby enabling each third power member 406 to drive linear degrees of freedom from different axes and ultimately drive the metal adsorption member to achieve universal position adjustment.
