DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] Reference Figures 1 to 7 As shown, a sealing device for the feeding end of a vibrating screen of the utility model comprises 1, and a 61 is fixedly installed on the top of the 1;

[0030] Also included is a sealing mechanism for sealing the top of the vibrating screen;

[0031] A 663 is fixedly installed on one side of the top of the 61, and the output shaft of the 663 is fixedly connected to 651. The outer surface of the 651 is threadedly connected to 652. 62 is opened on both sides of the 61, and a plurality of 621 are slidably installed on the inner surface of the 62. A 6211 is fixedly installed on the top of the 621, and the 652 is slidably installed on one side of the 61. The 652 is fixedly connected to the 621 located near the top of the 61.

[0032] To clean and inspect the inside of the vibrating screen, the upper seals must be completely removed, which will cause dust to overflow and affect the surrounding environment. In order to avoid dust overflow when the vibrating screen is working and to facilitate the inspection and maintenance of the vibrating screen, the top of the vibrating screen needs to be covered.

[0033] First, when the vibrating screen is working, a number of 621 are evenly distributed on the top of 61, and the evenly distributed 621 pulls 6211 apart, so that 6211 can completely cover the top of 61. Before use, a number of 621 are gathered on one side of the top of 61 in sequence. When 6211 needs to be unfolded, 651 is rotated with 663, and 651 can drive 652 to slide along the outer surface of 61. When 652 slides, it also slides with 621. Under the pull of 652, 6211 is completely unfolded and covers the top of 61.

[0034] When the vibrating screen needs to be inspected, 6211 covering the top of 61 needs to be removed. At this time, 651 is rotated with 661, and 652 at the top of 61 slides down along 651 with 621, and 6211 also slides down with 621 and gathers together to complete the storage of 6211.

[0035] Further, such as Figure 2 As shown, there are four 1, two 11 are fixedly installed between two adjacent 1, and one side of the two 11 is fixedly connected with 12.

[0036] When the vibrating screen is working, it will generate greater vibration. In order to ensure the stability of the vibrating screen, the four 1s are reinforced by two 11s.

[0037] Further, such as Figure 2 and Figure 3 As shown, the top of 12 is fixedly connected with 31, the output shaft of 31 is fixedly connected with 32, the middle of 32 is fixedly connected with 33, the other end of 33 is fixedly connected with 34, one side of 34 is fixedly connected with 35, four 36 are fixedly installed on the outer surface of 35, the four 36 are respectively located at the two ends of 35 in a group of two, and 35 is rotatably installed in the middle of 61;

[0038] The top of 1 is fixedly installed with 41, the top of 41 is fixedly connected with 42, one side of 42 is fixedly connected with 43, and 43 is fixedly installed on one side of 61.

[0039] The vibrating screen needs to generate vibration all the time when it is working. Here, 31 drives 35 to rotate. Since 35 is no longer on the same axis as the output shaft of 31 when rotating, in order to protect 31, 32 is connected to 31 and 35. The soft connection method is used to reduce the impact of the vibrating screen on 31 during vibration. The vibrating screen is driven by an eccentric swing block. The positions of two 36 in a group can be adjusted to adjust the vibration amplitude. In combination with four 41, the impact of 61 on 1 during vibration can also be reduced.

[0040] Further, such as Figure 4 and Figure 6 As shown, 51 is fixedly installed on one side of 61, one end of 51 penetrates into the inner cavity of 61, 52 is fixedly installed on the inner surface of 51, 53 is fixedly installed on one side of 52, and the output shaft of 53 is fixedly connected with 54;

[0041] A 63 is fixedly installed in the middle of the inner surface of the 61, a 64 is fixedly connected to one end of the 61, a 641 is fixedly connected to the 61 located at the upper part of the other side, and a 642 is fixedly connected to the 61 located at the lower part.

[0042] When the vibrating screen is working, a lot of dust will be generated, and the top of the vibrating screen is covered with 6211. Although the dust cannot be blown out through the top of the vibrating screen, the dust will be blown out through 64 or 641. In order to control the outflow of dust, 53 drives 54 to rotate, and the dust generated inside 61 is sucked out to reduce the amount of dust flowing out of 64 and 641. 63 divides 61 into two layers, upper and lower.

[0043] Further, such as Figure 6 and Figure 7 As shown, 65 is fixedly installed on both sides of 61, 651 is rotatably installed on one side of 65, and there are two 652, which are slidably installed on both sides of 61 respectively;

[0044] The top of the 61 is fixedly installed with 66, the two 651s penetrate and extend out of 66 and are rotatably connected with 66, the tops of the two 651s are fixedly connected with 661, the two 661s are rotatably installed on one side of 66, the outer surfaces of the two 661s are commonly wound and connected with 662, one side of the 61 is fixedly installed with 664, the top of 664 is fixedly connected with 663, and the output shaft of 663 is fixedly installed on one side of 661.

[0045] In order to use the vibrating screen, the vibrating screen needs to be frequently inspected and repaired, so 6211 needs to be frequently retracted and released. In order to make the retraction and release of 6211 more convenient, 6211 needs to be able to slide smoothly on the top of 61 during use. Therefore, power is provided by 663, and 662 is used to rotate the two 661. The two 661 rotate with the two 651, and the two 651 drive 652 to slide. The two 652 can also slide with 621 while sliding, and 621 slides along 62.

[0046] Working principle: When in use, 31 rotates with 35 through 33, and cooperates with four 36 and four 41 to make 61 vibrate. First, the raw materials to be screened are input into 61 through 64. Since 61 is in a vibrating state, the smaller raw materials fall into 61 at the bottom and pass through 642, and the larger raw materials flow out through 641.

[0047] Before use, 6211 needs to be covered on 61. Driven by 663, the two 651 rotate. The two 651 drive the two 652 to slide along the side wall of 61. The two 652 jointly control the sliding of 621. 621 slides upward with 6211. Several gathered 621 gradually disperse in the process of rising. 6211 is completely unfolded and completely covers the top of 61.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
