[0018] The following is combined with Figures 1 - 3 This application is described in further detail.

[0019] This embodiment of the present application discloses a classification device suitable for the production and processing of plastic runway particles. Refer to Figure 1 and Figure 2 as well as Figure 3 , a classification device suitable for the production and processing of plastic runway particles, in which two support cross plates 2 are symmetrically provided with two support frames 1 between them, forming the support frame of the device main body to ensure the overall stability of the device. At the same time, a first enclosure 12, a second enclosure 18 and a third enclosure 8 are successively arranged on the two support cross plates 2 from top to bottom, and the first enclosure 12, the second enclosure 18 and the third enclosure 8 are internally connected in sequence, facilitating the graded falling of particles. At the same time, a first sieve plate 14, a second sieve plate 15 and a third sieve plate 16 are respectively installed inside the first enclosure 12, the second enclosure 18 and the third enclosure 8, and the screening aperture of the first sieve plate 14 is larger than that of the second sieve plate 15, while the screening aperture of the second sieve plate 15 is larger than that of the third sieve plate 16, so as to realize the graded screening of particles;

[0020] A driving motor 11 is installed outside the upper support cross plate 2, the output end of the driving motor 11 is installed with a driving main shaft 9, and the driving main shaft 9 sequentially penetrates through the first sieve plate 14, the second sieve plate 15 and the third sieve plate 16, facilitating the driving main shaft 9 to rotate inside the first enclosure 12, the second enclosure 18 and the third enclosure 8 by driving the driving motor 11. At the same time, the bottom of the driving main shaft 9 rotates with the upper surface of the lower support cross plate 2, providing support for the lower part of the driving main shaft 9 to ensure the stability of the driving main shaft 9 during rotation. A plurality of groups of stirring rods 17 are circumferentially arranged on the driving main shaft 9 from top to bottom, and each group of stirring rods 17 is respectively placed inside the corresponding first enclosure 12, the second enclosure 18 and the third enclosure 8. The driving main shaft 9 can synchronously drive a plurality of groups of circumferentially arranged stirring rods 17 to rotate inside the first enclosure 12, the second enclosure 18 and the third enclosure 8, continuously colliding with the particles above the first sieve plate 14, the second sieve plate 15 and the third sieve plate 16, facilitating the separation of the particles adhered together, and effectively reducing the appearance of defective finished particles.

[0021] Refer to Figure 1 and Figure 2 as well as Figure 3 , rectangular openings are provided inside the first sieve plate 14, the second sieve plate 15 and the third sieve plate 16 to prevent the driving main shaft 9 from affecting the reciprocating movement of the first sieve plate 14, the second sieve plate 15 and the third sieve plate 16. At the same time, rectangular openings identical to those of the first sieve plate 14 are also provided on the top wall of the support cross plate 2, facilitating the driving main shaft 9 to penetrate the top wall of the first enclosure 12 and the reciprocating movement of the first enclosure 12.

[0022] Refer to Figure 1 and Figure 2 as well as Figure 3A plurality of circular cover plates 10 are fixed from top to bottom on the outside of the driving main shaft 9, and the plurality of circular cover plates 10 are respectively attached to the top wall of the No. 1 enclosure 12 and the upper surfaces of the No. 1 sieve plate 14, the No. 2 sieve plate 15 and the No. 3 sieve plate 16. The circular cover plates 10 are convenient for closing the rectangular openings opened by the No. 1 sieve plate 14, the No. 2 sieve plate 15, the No. 3 sieve plate 16 and the No. 1 enclosure 12, so as to prevent the particles screened by the No. 1 sieve plate 14, the No. 2 sieve plate 15 and the No. 3 sieve plate 16 from falling directly from the opened rectangular openings, thereby ensuring the screening effect of the particles.

[0023] Reference Figure 1 and Figure 2 Rectangular sleeves 6 are installed on both sides of the exterior of the No. 1 enclosure 12, the No. 2 enclosure 18 and the No. 3 enclosure 8. A guide rod 7 runs through the interior of the rectangular sleeve 6, and both ends of the guide rod 7 are fixed between the two support frames 1. The rectangular sleeve 6 and the guide rod 7 cooperate with each other to provide support for the No. 1 enclosure 12, the No. 2 enclosure 18 and the No. 3 enclosure 8, while ensuring that the No. 1 enclosure 12, the No. 2 enclosure 18 and the No. 3 enclosure 8 form a reciprocating motion along a fixed trajectory, which is convenient for screening particles.

[0024] Reference Figure 1 and Figure 2 In the device, a fixed plate 5 is installed inside one side support frame 1, and two hydraulic cylinders 4 are symmetrically installed at both ends of the fixed plate 5, and the telescopic ends of the hydraulic cylinders 4 are fixed to the side of the No. 2 enclosure 18, so that the hydraulic cylinders 4 can provide power for the No. 1 enclosure 12, the No. 2 enclosure 18 and the No. 3 enclosure 8 to reciprocate between the two support frames 1.

[0025] Reference Figure 1 and Figure 2 In the device, a discharge door 13 is installed on the same side of the No. 1 enclosure 12, the No. 2 enclosure 18 and the No. 3 enclosure 8. Through the discharge door 13, it is convenient for the staff to clean the screened particles inside the No. 1 enclosure 12, the No. 2 enclosure 18 and the No. 3 enclosure 8. At the same time, a feeding port 3 is provided on the side of the No. 1 enclosure 12 away from the discharge door 13, so that the plastic particles that need to be screened can be added into the No. 1 enclosure 12 through the feeding port 3.

[0026] The implementation principle of a grading device for the production and processing of plastic track particles in the present application embodiment is as follows:

[0027] When in use, the particles to be screened are quantitatively added into the No. 1 enclosure 12 through the feeding port 3, and then the hydraulic cylinder 4 and the driving motor 11 are started, and the rectangular sleeve 6 is sleeved on the outside of the guide rod 7, so that the telescopic end of the hydraulic cylinder 4 can drive the No. 2 enclosure 18, the No. 1 enclosure 12 and the No. 3 enclosure 8 to reciprocate, and then the No. 1 sieve plate 14, the No. 2 sieve plate 15 and the No. 3 sieve plate 16 to reciprocate synchronously, so that the plastic particles can be graded and screened in sequence according to the diameter size;

[0028] Meanwhile, the output end of the driving motor 11 can drive the driving main shaft 9 to rotate. Then, the driving main shaft 9 can synchronously drive a plurality of stirring rods 17 arranged circumferentially to rotate inside the first enclosure 12, the second enclosure 18, and the third enclosure 8, continuously colliding with the particles above the first sieve plate 14, the second sieve plate 15, and the third sieve plate 16, facilitating the separation of the particles adhered together, effectively reducing the occurrence of defective particles in the finished product, and improving the quality of the particles of the finished product after classification.
