[0023] It should be understood that the specific embodiments described herein are merely exemplary and not intended to limit the present application.

[0024] As Figs. 1-3 shown: a sorting device for scrap iron, including multiple groups of sorting units, each group of sorting units including a main conveying belt 1, a branch conveying belt 2 and a sorting assembly 3, the branch conveying belt 2 is vertically connected to the side of the main conveying belt 1, the sorting assembly 3 is arranged at the connection between the branch conveying belt 2 and the main conveying belt 1, and the main conveying belts 1 in each sorting unit are connected in series.

[0025] The sorting assembly 3 includes a push cylinder 31 and a group of metal spectrum analyzers 32, the push cylinder 31 can push the scrap iron to the branch conveying belt 2, and the metal spectrum analyzer 32 can detect the element content in the scrap iron.

[0026] In use, the scrap iron moves on the main conveying belt, and after the type of the scrap iron is detected by the metal spectrum analyzer 32 of the sorting assembly 3, the push cylinder 31 pushes the scrap iron of the same type to the branch conveying belt 2 to complete automatic and accurate sorting. Multiple sorting units can be combined to complete the sorting of multiple types of scrap iron.

[0027] In one preferred embodiment, the main conveying belt 1 is provided with a cylinder support 11 on the side of the branch conveying belt 2, the push cylinder 31 is arranged on the cylinder support 11, the main conveying belt 1 is provided with a mounting column 12 on both sides, the metal spectrum analyzer 32 is arranged on the mounting column 12, and the mounting column is diagonally arranged.

[0028] Please refer to Fig. 2The piston rod end of the push cylinder 31 is connected with a push plate 33, the push plate 33 is L-shaped, and the baffle 34 is arranged on the mounting column 12 at the rear end of the push cylinder 31. The push cylinder 31 is connected with one side of the push plate 33, the other side of the push plate 33 faces the tail of the push cylinder 31, and the baffle 34 is rotatably arranged on the mounting column 12. When the metal spectrum analyzer 32 detects that the piece of scrap iron is the sorting target of the sorting unit, the baffle 34 rotates to close the main conveying belt 1, and the push cylinder 31 pushes out the push plate 33, one side of the push plate 33 pushes the scrap iron to the branch conveying belt 2, and the other side can temporarily block the subsequent incoming material to avoid confusion. Since the conveying belt is always running during sorting, in order to avoid the scrap iron being sent to deviate from the branch conveying belt 2 under the driving of the conveying belt and the pushing of the push plate 33, the scrap iron is blocked by the baffle 34.

[0029] The side of the main conveying belt 1 and the side of the branch conveying belt 2 are provided with a driving motor 4.

[0030] In addition, an electric control box 13 is further included, the electric control box 13 is arranged on the side of the main conveying belt 1, and the driving motor 4, the push cylinder 31 and the metal spectrum analyzer 32 are electrically connected with the electric control box 13. The metal spectrum analyzer 32 feeds back the detection result to the electric control box 13, the electric control box 13 sends an instruction according to the information, and controls the push cylinder 31 and the baffle 34 in the corresponding sorting unit to act or not to act.

[0031] Specifically, the end of the branch conveying belt 2 and the end of the main conveying belt 1 are provided with a material receiving frame, and the branch conveying belt 2 and the main conveying belt 1 are both belt type conveying belts. The material receiving frame is not shown in the figure, and the material receiving frame is used for collecting scrap irons of the same type. The belt type conveying belt is beneficial to the conveying of metal pieces, and the use life of the conveying belt is improved by selecting a wear-resistant and corrosion-resistant conveying belt.

[0032] The push cylinder 31 includes a group of parallel arranged cylinders. Since the self-weight of the scrap iron is large, a pushing force needs to be provided to push the scrap iron, and the time required is preferably as short as possible. The parallel arranged cylinders can provide sufficient pushing force, and preferably two cylinders are arranged in parallel, which is beneficial to saving installation space.
