Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0038] Please refer to the attached Figures 1 to 14 A screen rod type screen gap adjustment mechanism according to some embodiments of the present invention is described.

[0041] Furthermore, the screen rod 1 includes a screen rod connecting portion 101 , a screen gap control piece 102 , and an end 103 .

[0042] The sieve gap control piece 102 is fixedly connected to both ends of the sieve rod connecting portion 101 , the end head 103 is fixedly connected to the outer end of the sieve gap control piece 102 , and the sieve gap control piece 102 is located at the sieve gap position of the sieve shaft 5 .

The setting of the end head 103 can effectively prevent material from getting stuck in the gap between the screen shaft 5 and the end of the screen slot control plate 102, thereby ensuring the normal rotation of the screen shaft 5.

[0044] Optionally, the screen rod 1 is made of wear-resistant material. In the embodiment of the present disclosure, the screen rod 1 may be made of wear-resistant alloy steel.

[0045] Furthermore, the sliding rod mechanism 2 includes a sliding bearing 201 , a sliding rod 202 , and a connecting end 203 .
