[0034] The screening assembly 6 includes a first screen cylinder 61, a gear ring 62 and a limiting ring 63 connected to the outside of the first screen cylinder 61.

A second hydraulic cylinder 68 is rotatably connected to one of the fixed rods 65. The movable end of the first hydraulic cylinder 68 is hinged to a rocker arm 67 through a pin. The other end of the rocker arm 67 is connected to the second screen cylinder 66. The second screen cylinder 66 is rotatably connected inside the first screen cylinder 61.

[0036] The working principle and usage process of this utility model are as follows: When the screening machine needs to be used, and when the angle of the screening component 6 needs to be adjusted, the first oil cylinder 21 is first controlled to extend or retract. The working first oil cylinder 21 can drive the second fixed frame 31 to rotate around the pin shaft, so that the angle between the second fixed frame 31 and the first fixed frame 11 changes. During this process, the working first oil cylinder 21 drives the two rotating rods 22 to rotate in the two limiting sleeves 12 respectively.

When organic matter is poured into the first screen cylinder 61 from the end near the limiting ring 63, the screening machine can control the screening time of the organic matter in the screening component 6 by controlling the angle of the screening component 6.

[0037] When it is necessary to screen the organic matter poured into the first sieve cylinder 61, the control motor 42 is activated. The activated motor 42 drives the first pulley 44 to rotate via the reducer 43. The rotating first pulley 44 drives the second pulley 46 to rotate via the belt 45. The rotating second pulley 46 drives the gear 47 to rotate outside the fixed shaft 48. The rotating gear 47 drives the first sieve cylinder 61 and several fixed rods 65 to rotate via the gear ring 62. The rotating fixed rods 65 drive the second hydraulic cylinder 68 to rotate synchronously. The organic matter is then filtered into the first sieve cylinder 61 and the second sieve cylinder 66. The second hydraulic cylinder 68 is controlled to extend or retract when the gap of the screening holes of the screening component 6 needs to be adjusted. The working second hydraulic cylinder 68 drives the second screen cylinder 66 to rotate inside the first screen cylinder 61 through the cantilever. During this process, the rotating cantilever can synchronously drive the second hydraulic cylinder 68 to rotate outside the fixed rod 65. The screening component 6 with the screening hole gap adjusted can screen out organic wood blocks of different sizes according to the actual situation. Debris and wood chips that are not large enough are screened out from the screen. This screening machine can screen out wood blocks of specific specifications with long strip screening holes.
