[0033] The present invention is further described in detail below in conjunction with specific embodiments:

[0034] like Figure 1-Figure 5 As shown, a grading and sorting device includes a detection mechanism 1 and a sorting mechanism, the sorting mechanism includes a conveying component 2, a separation component 3 and a sorting component 4, the separation component 3 is arranged above the sorting component 4, the conveying component 2 is arranged above the separation component 3, and the detection mechanism 1 is arranged above the conveying component 2. In this embodiment, the detection mechanism 1 is a visual detection system or an infrared detection system. The conveying component 2 is a second conveyor belt 21 and is a flat conveyor belt. The conveying component 2 is arranged in parallel with the separation component 3, and the downstream end of the separation component 3 extends out of the downstream end of the conveying component 2, so that the material can be directly conveyed from the conveying component 2 to the separation component 3. Specifically, when the material is transmitted on the second conveyor belt 21 and passes through the detection mechanism 1, the detection mechanism 1 can obtain the corresponding reflection spectrum, collect various information of the material, and compare it with the information in the database, and automatically classify the material into grades; the material continues to be transmitted to the separation component 3, and by controlling the transmission rhythm of the separation component 3, there is only one material between every two groups of pushing plates; it continues to be transmitted to the sorting component 4, and a plurality of sorting devices 42 are arranged on the sorting component 4, each sorting device 42 corresponds to a classification grade, and when the material is transmitted to the sorting device 42 of the corresponding grade on the sorting component 4, the sorting device 42 moves and falls into the collection box 5 below it, and the sorting is completed.

[0035] The separation component 3 includes a first conveyor belt 31, on which a plurality of pusher plates 32 are arranged. The pusher plates 32 move in a circular motion under the drive of the first conveyor belt 31. When the pusher plates 32 move to the bottom of the first conveyor belt 31 along with the first conveyor belt 31, the pusher plates 32 are cross-connected with the sorting component 4. In this embodiment, the first conveyor belt 31 is provided with a plurality of pusher plates 32 arranged in parallel at intervals, and the plurality of first conveyor belts 31 move synchronously; the pusher plates 32 are fixedly connected to the first conveyor belt 31, and a plurality of pusher plates 32 are evenly arranged and installed on each first conveyor belt 31, and the pusher plates 32 on the plurality of first conveyor belts 31 are all arranged in parallel. When the plurality of first conveyor belts 31 are running at the same time, a loading area 32a is formed between every two rows of pusher plates 32, and each loading area 32a can carry one material at a time by controlling the conveying rhythm.

[0036] In addition, in order to prevent the material from falling on the push plate 32 when being transferred from the conveying component 2 to the separating component 3, a material blocking device 22 is provided at the downstream end of the conveying component 2, and a sensor (not shown in the figure) that can sense the push plate can be provided on the separating component. The sensor can be placed directly below the second baffle 223. When the sensor senses the push plate, the second driving device 221 drives the first baffle 222 to rotate, so that the first baffle 222 and the second baffle 223 collide. At this time, if there is material being transferred on the conveying component 2, the material will fall between the first baffle 222 and the second baffle 223, and will not fall on the separating component. When the sensor does not sense the push plate, the second driving device 221 drives the first baffle 222 away from the second baffle 223, so that the material falls. At this time, the material can enter the loading area 32a. This structural design can completely avoid the interference between the material and the push plate during transmission.

[0037] The sorting assembly 4 includes a plurality of second guide plate groups 41, and a second gap 41a is formed between the plurality of second guide plate groups 41; each second guide plate group 41 is composed of a plurality of second guide plates 411 arranged in parallel, and a third gap 411a is formed between two adjacent second guide plates 411, and when the push plate 32 moves to the bottom of the separation assembly 3, the end portion extends into the third gap 411a and moves along the third gap 411a;

[0038] A sorting device 42 is arranged in the second gap 41a, and a collecting box 5 is arranged directly below the sorting device 42. There are multiple sorting devices 42, and there are multiple corresponding collecting boxes 5. A plurality of first guide plates 43 are connected to the upper end of the second guide plate 411 at the upper end of the sorting component 4, and the plurality of first guide plates 43 are connected to the second guide plate 411 in a one-to-one correspondence; the end of the first guide plate 43 away from the second guide plate 411 is arranged above the separation component 3. The first guide plate 43 is arc-shaped, and the arc surface forms a concentric circle with the rotating shaft of the lower end of the first conveyor belt 31. The first guide plates 43 are spaced apart from each other to form a first gap 43a. When the push plate 32 moves with the first conveyor belt 31, the end of the push plate 32 extends into the first gap 43a and moves along the first gap 43a. In this embodiment, when the push plate 32 follows the first conveyor belt 31 to the downstream end of the separation component 3, the end of the push plate 32 extends into the first gap 43a and continues to move along the first gap 43a to the third gap 411a until the push plate 32 follows the first conveyor belt 31 to the downstream end of the sorting component 4. When there is material in the loading area 32a, the material is pushed by the push plate 32 and can fall onto the second guide plate 411 along the arc surface of the first guide plate 43. When the push plate 32 moves to the second guide plate 411, it continues to push the material to be transmitted on the second guide plate 411. This arrangement can ensure that the posture of the material is consistent during transmission, especially for long strips of material, to avoid being squeezed or bumped due to changes in posture during the transmission process. It can also ensure that the material remains neatly stacked when entering the collection box 5, facilitating subsequent collection.

[0039] The sorting device 42 includes a first driving device 421 and a plurality of sorting plates 422. The first driving device 421 is connected below the sorting assembly 4. The plurality of sorting plates 422 are connected to the second guide plates 411 one by one. The sorting plates 422 include a first connecting plate 4221 and a second connecting plate 4222. The two ends of the first connecting plate 4221 are respectively connected to the second guide plates 411 on the two adjacent second guide plate groups 41. The second connecting plate 4222 is connected to the lower end of the first connecting plate 4221, and one end away from the first connecting plate 4221 is connected to the first driving device 421. The upper end of the first connecting plate 4221 is lower than the upper surface of the second guide plate 411, and the lower end is rotatably connected to the second guide plate 411, and the lower end of the first connecting plate 4221 is higher than the upper surface of the second guide plate 411. The first driving device 421 can drive the first connecting plate 4221 to rotate along the connection between the first connecting plate 4221 and the second guide plate 411 through the second connecting plate 4222, so that the upper end of the first connecting plate 4221 moves upward.

[0040] In this embodiment, a collecting box 5 is provided at the lower end of each sorting device 42, and each collecting box 5 corresponds to a different grade; when the material is conveyed on the sorting component 4, according to the detection and classification of the detection mechanism 1, the corresponding sorting device 42 is started at the collecting box 5 of the corresponding grade, so that the material falls into the corresponding collecting box 5, and the graded sorting is completed. Specifically, the first driving device 421 pushes the second connecting plate 4222, and the first connecting plate 4221 rotates along the connection between it and the second guide plate 411, so that the upper end of the first connecting plate 4221 is tilted, and the material automatically falls from the second gap 41a into the collecting box 5. It should be noted that in this embodiment, Figure 1 As shown, five sorting devices 42 and six collecting boxes 5 are provided, and the materials can be classified into six grades. Of course, the materials can also be classified into less than five grades. The sorting devices 42 and collecting boxes 5 can also be added according to actual needs to classify the materials into more grades.

[0041] In other preferred embodiments, Figure 3 As shown, in order to further prevent the material from being stuck at the connection, a notch 4111 is set at the downstream end of the second guide plate 411, and the upstream end of the first connecting plate 4221 is connected in the notch 4111. When the material passes through, it can move smoothly from the second guide plate 411 to the first connecting plate 4221.
