Description

TECHNICAL FIELD

[0002] As an excellent material sorting device, the color sorter is widely applied in the industries of grain processing and ore sorting, and the color sorter as a whole comprises key components such as a feeding conveying mechanism, an optical signal acquisition and identification mechanism, and a sorting and rejecting mechanism. The sorting and rejecting mechanism is used to reject the color-irregular materials identified by the optical signal acquisition and identification mechanism, so as to realize the sorting of good and bad materials. The existing small materials such as beans and rice are mostly rejected by blowing, specifically, a gas nozzle is arranged above the material falling path at the discharge end of the conveying belt, the gas nozzle is communicated with a gas source, when the optical signal acquisition and identification mechanism acquires color-irregular materials, the signal is processed and transmitted through an intelligent algorithm, and then the blowing action of a high-pressure spray valve is controlled to change the falling path of the color-irregular materials, so that the color-irregular materials fall into a waste material container; and the materials meeting the requirements are freely thrown into a finished product container of the color sorter, thereby completing the sorting of the materials. For reference can be made to the related content disclosed in the Chinese patent application for invention with the publication number CN114871150A, namely, a clamping and relay type intelligent track color sorter.

[0034] Embodiment one

[0035] Please refer to Figure 1As shown, the present embodiment provides a push plate type rejection mechanism 300, which is mainly used in a color sorter to achieve better rejection and separation of light and fluffy materials such as leaves. The color sorter also includes an inlet mechanism 100 and an optical signal acquisition and identification mechanism 200, the inlet mechanism 100 is connected to one end of the optical signal acquisition and identification mechanism 200, and the other end of the optical signal acquisition and identification mechanism 200 is connected to the push plate type rejection mechanism 300. During separation, the material is transported from the inlet mechanism 100 to the optical signal acquisition and identification mechanism 200 through dispersion and arrangement, and when the optical signal acquisition and identification mechanism 200 acquires a foreign material, the signal is processed and transmitted through an intelligent algorithm, and the material is transported to the push plate type rejection mechanism 300 for separation.

[0036] Please refer to Figures 2-7 As shown, the push plate type rejection mechanism 300 includes a waste material hopper 1 and a finished product material hopper 2, and after the material flows out of the optical signal acquisition and identification mechanism 200, it falls into the finished product material hopper 2 along the throwing path 3.

[0037] Eight push plate assemblies 4 for sending bad materials in the material to the waste material hopper 1 and a bracket for mounting the eight push plate assemblies 4 are provided above the finished product material hopper 2. Corresponding to the formation of unitized push plate assemblies 4, each push plate assembly corresponds to a small rejection area, achieving small-range single-point rejection. Of course, other numbers of push plate assemblies 4 can be set according to actual use requirements. For example, if the range of material falling is wider, a certain number of push plate assemblies need to be increased to ensure that the total width of the push plate assemblies 4 is greater than the width of the material laid flat, and all bad materials mixed in the material can be rejected.

[0038] Please refer to Figures 2-5 As shown, the eight push plate assemblies 4 are fixed in two rows on the bracket, four in each row, and the two rows of push plate assemblies 4 are arranged in a staggered manner, that is, the push plate assemblies in the second row are located at the gap between the adjacent push plate assemblies in the first row. The push plate assembly 4 includes a push plate 401 and a guide rod air cylinder 402 for driving the push plate 401 to move. One end of the guide rod air cylinder 402 is fixedly connected with the bracket, and the other end is fixedly connected with one end of the push plate 401. The guide rod air cylinder 402 has low gas pressure requirements and low gas consumption, and has low requirements for air compressors and other accessory devices, so that the customer's on-site conditions are more easily met, and the economic benefits are improved. Of course, other types of telescopic cylinders can also be used to achieve the same functional effect. In the direction perpendicular to the surface of the push plate 401, the push plate 401 of the first adjacent two push plate assemblies 4 and the push plate 401 of the push plate assembly 4 located at the gap of the second row overlap to cover the falling range of the material. In addition, the two side edges of the push plate 401 have a folding edge 4011 to prevent the material from sliding off the two sides of the push plate 401.

[0039] Please refer to Figure 7 and Figure 8As shown, the push plate 401 is arranged perpendicular to the material throwing path 3. At the same time, the push plate 401 is inclined downward along the extension direction of the telescopic cylinder, and the angle between the push plate 401 and the extension direction of the telescopic cylinder is 20°. After the material hits the push plate 401, it is more likely to fall into the waste collecting hopper 1.

[0040] When the material is running and the optical signal acquisition and recognition mechanism 200 acquires a foreign color material, the signal is processed and transmitted by an intelligent algorithm. The guide rod cylinder 402 gas circuit at the corresponding position is connected, driving the push plate 401 to extend in the direction of the material falling path, and the waste material is blocked and falls into the waste collecting hopper 1, realizing timed and fixed-point rejection of waste material, accurate positioning, small-range rejection, and high efficiency and low loss.

[0041] Embodiment two

[0042] Based on embodiment one, the difference between embodiment two is:

[0043] Please refer to Figure 2 , Figure 3 and Figure 6 , Figure 7 As shown, the support includes a first support 5 and a second support 6. The first support 5 is in the shape of “n”. The two ends of the first support 5 are fixedly connected to the two sides of the finished product collecting hopper 2 and are arranged above the finished product collecting hopper 2. The second support 6 is in the shape of “7”. The lower surface of the first support 5 is provided with a plurality of first long circular holes 501. One side surface of the second support 6 is fixedly connected to the first long circular holes 501 by bolts, so as to integrally adjust the initial positions of the plurality of push plate assemblies 4 relative to the material throwing path 3. The other side surface of the second support 6 is provided with a plurality of second long circular holes 601. The telescopic cylinders are fixedly connected to the second long circular holes 601 by bolts, so as to independently adjust the initial positions of each push plate assembly 4 relative to the material throwing path 3. The two-stage adjustment can realize a larger adjustable range of the positions of the telescopic cylinders, higher adjustment efficiency, more compatible material varieties, and better universality of the equipment.

[0044] Embodiment three

[0045] Based on embodiment one or embodiment two, the difference between embodiment three is:

[0046] Please refer to Figure 7 As shown, a separation adjusting plate 7 is arranged between the waste collecting hopper 1 and the finished product collecting hopper 2. The connection between the separation adjusting plate 7 and the waste collecting hopper 1 and the finished product collecting hopper 2 is hinged. By rotating the separation adjusting plate 7, the size of the inlet of the waste collecting hopper 1 and the size of the inlet of the finished product collecting hopper 2 are adjusted. After adjustment, the separation adjusting plate 7 is locked by bolts and the inner wall of the hopper. For different types of materials, adjusting the separation adjusting plate 7 ensures that the materials can completely fall into the finished product collecting hopper 2 when normally thrown, and at the same time, the waste materials can completely fall into the waste collecting hopper 1 when blocked by the push plate assembly 4.
