DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] Reference Figure 1-Figure 3As shown, a discharge end cover plate adjustment mechanism of a three-drum dryer comprises an outer drum body 1, a cover body 3 is arranged on the right side of the outer drum body 1, and a discharge pipe 4 is installed on the cover body 3; it also comprises a guiding movement mechanism, the guiding movement mechanism comprises a hollow ring 2 fixedly sleeved on the outside of the outer drum body 1, a piston cylinder 7 is fixedly connected to the right side of the hollow ring 2, a second piston block 14 which can slide left and right is arranged in the piston cylinder 7, a plurality of second piston blocks 14 are fixedly connected to the right sides of a piston rod 8, and the right sides of a plurality of piston rods 8 are fixedly connected to the cover body 3.

[0015] An annular sealing gasket 15 is fixedly connected to the outer side of the right side of the outer cylinder body 1. The outer side of the annular sealing gasket 15 contacts the inner side of the cover body 3. The use of the annular sealing gasket 15 can ensure the sealing performance of the sliding connection.

[0016] The driving mechanism also includes a driving mechanism, which cooperates with the guiding and moving mechanism. The driving mechanism includes a rectangular box 5 fixedly connected to the upper end of the outer cylinder body 1, a columnar cavity 9 is arranged in the rectangular box 5, and a first piston block 10 that can slide up and down is arranged in the columnar cavity 9. The inner bottom space of the columnar cavity 9 is connected to the interior of the hollow ring 2 through a connecting pipe 12, and the interior of the hollow ring 2 is connected to multiple piston cylinders 7 through a connecting port 13. A screw 6 is arranged through the inner top space of the columnar cavity 9, and the screw 6 is rotatably connected to the top of the columnar cavity 9. A thread groove 11 is opened at the upper end of the first piston block 10, and the lower end of the screw 6 extends to the inside of the thread groove 11 and is threadedly connected to the inner wall of the thread groove 11.
