[0027] In order to solve the problem that fertilizer particles are easily blocked by the screen when the organic fertilizer is screened by the drum screen in organic fertilizer production, which affects the screening efficiency of the drum screen for organic fertilizer, such as Figures 1 to 4 A drum screen for organic fertilizer production shown in the figure includes a bottom plate 1 and a fixed barrel 2 for screening organic fertilizer. The fixed barrel 2 is provided to store fine particles of the organic fertilizer. A rotating motor 3 is installed on the side of the fixed barrel 2. Power is provided by rotating the output shaft of the rotating motor 3. The output shaft of the rotating motor 3 is fixedly connected to a baffle 4. The organic fertilizer is shielded by providing the baffle 4. A screening tube 5 with a plurality of through holes is fixedly connected to the side of the baffle 4. The organic fertilizer is screened through the plurality of through holes on the surface of the screening tube 5, thereby realizing the screening of the organic fertilizer. A knob 11 is rotatably connected to the top end of the fixed barrel 2, and a threaded rod 12 is fixedly connected to the bottom end of the knob 11.
[0028] By setting the knob 11, it is convenient to rotate the threaded rod 12. A rotating block 13 is fixedly connected to the side of the threaded rod 12. The top of the rotating block 13 is in contact with the fixed barrel 2. The rotating position of the threaded rod 12 is fixed by setting the rotating block 13. The threaded rod 12 is threadedly connected to the threaded block 14. By rotating the threaded rod 12, the threaded block 14 is moved along the thread path of the threaded rod 12. A moving rod 15 is fixedly connected to the bottom end of the threaded block 14. A sliding groove is provided at the top of the moving rod 15. The moving rod 15 is slidably connected to the limiting block 16 through the sliding groove, and the limiting block 16 is cylindrical, which is convenient for realizing the relative rotation of the moving rod 15 and the limiting block 16. The limiting block 16 is provided to prevent the moving rod 15 from falling off, thereby improving the structural stability of the drum rotary screen parts.
[0029] The top of the limit block 16 is fixedly connected to the threaded rod 12, and the bottom of the movable rod 15 is fixedly connected to a cleaning plate 17. The brush at the bottom of the cleaning plate 17 contacts the screening tube 5. The organic fertilizer blocked in the through hole of the screening tube 5 is cleaned by the brush installed at the bottom of the cleaning plate 17 to prevent the organic fertilizer from being blocked and affecting the screening efficiency of the drum screen for the organic fertilizer. By conveniently moving the position of the cleaning plate 17, the brush is more closely in contact with the screening tube 5, thereby improving the cleaning effect.
[0030] Both ends of the outer wall of the screening tube 5 are rotatably connected to the limit ring 6, and the rotation position of the screening tube 5 is fixed by setting the limit ring 6. The top and bottom ends of the limit ring 6 are fixedly connected to the limit rod 7. The outer peripheral side of the screening tube 5 is fixedly connected with a fixing ring 8. The end of the limit rod 7 away from the limit ring 6 is fixedly connected to the fixed barrel 2. The position of the limit ring 6 is fixed by setting the limit rod 7. The baffle 4 and the adjacent sides of the fixing ring 8 are respectively in contact with the limit ring 6, thereby further fixing the rotation position of the screening tube 5. A screening door 9 is installed at the end of the fixing ring 8 away from the screening tube 5. The screening door 9 is set to facilitate the placement and removal of organic fertilizers in the screening tube 5. The outer wall of the fixed barrel 2 is fixedly connected with a support plate 18.
[0031] The fixed barrel 2 is supported by a support plate 18, and a fixed door 10 is installed at one end of the fixed barrel 2 away from the rotating motor 3.

The bottom end of the support plate 18 is fixedly connected to a rotating rod 19, and both ends of the side of the rotating rod 19 are rotatably connected to fixed plates 20. The rotating position of the rotating rod 19 is fixed by setting the fixed plate 20. The bottom end of the fixed plate 20 is fixedly connected to the bottom plate 1, and a groove is provided at the top of the bottom plate 1. The bottom plate 1 is rotatably connected to a screw rod 21 through the groove. A driving motor 25 is installed on the side of the bottom plate 1, and the output shaft of the driving motor 25 is fixedly connected to the screw rod 21. The output shaft of the driving motor 25 is rotated to provide power, thereby driving the screw rod 21 to rotate. The screw rod 21 is threadedly connected to a screw block 22, so that the screw block 22 moves along the thread path of the screw rod 21, and the screw block 22 is rotatably connected to a movable plate 23 through a pin shaft.
[0032] The movable plate 23 is pushed by the screw block 22. One end of the movable plate 23 away from the screw block 22 is rotatably connected to the limit plate 24 through a pin shaft. The angle of the movable plate 23 is changed to adjust the height of the limit plate 24. The top of the limit plate 24 is fixedly connected to the fixed barrel 2, so that the fixed barrel 2 rotates with the rotating rod 19 as the center. By adjusting the height of the open end of the fixed barrel 2, the organic fertilizer can be conveniently put in and taken out.

The universal wheels 28 are conveniently provided to move the drum screen.
[0033] The rotating motor 3 and the driving motor 25 are both prior arts, and their working principles, sizes and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
[0034] How it works
[0035] When using the drum screen for producing organic fertilizer, the user opens the fixed door 10, then opens the screening door 9, starts the driving motor 25, rotates the screw rod 21, and then moves the screw block 22 along the thread path of the screw rod 21, pushes the movable plate 23 through the screw block 22, and then pushes the limit plate 24, so that the fixed barrel 2 rotates with the rotating rod 19 as the center of the circle, so that the opening end of the fixed barrel 2 is higher than the end of the fixed barrel 2 close to the rotating motor 3, so that it is convenient to put the organic fertilizer to be screened into the screening tube 5, close the screening door 9 and the fixed door 10, start the rotating motor 3, and the output shaft of the rotating motor 3 drives the baffle 4 to rotate, and then drives the screening tube 5 to rotate, so as to realize the screening of the organic fertilizer, and the fine particles of organic fertilizer pass through the plurality of through holes on the surface of the screening tube 5 and flow into the fixed barrel 2, so as to prevent the plurality of through holes of the screening tube 5 from being blocked by the organic fertilizer.
[0036] The screen tube 5 is cleaned by arranging a brush at the bottom of the cleaning plate 17 to prevent the screen tube 5 from being blocked and affecting the screening efficiency of the organic fertilizer. The cleaning plate 17 is prevented from being used for a long time and the brush is worn, resulting in loose contact between the brush and the screen tube 5. The knob 11 is rotated to drive the threaded rod 12 to rotate, so that the threaded block 14 moves along the threaded path of the threaded rod 12. During the transmission process, the cleaning plate 17 is driven to move, so that the brush at the bottom of the cleaning plate 17 is in closer contact with the screen tube 5, thereby improving the cleaning effect of the organic fertilizer blocked in the several through holes on the surface of the screen tube 5. When the organic fertilizer is completely screened, the driving motor 25 is started to make the opening of the fixed barrel 2 lower than the end of the fixed barrel 2 close to the rotating motor 3, and then the fixed door 10 is opened to allow the completely screened fine organic fertilizer to flow out. After the organic fertilizer in the fixed barrel 2 is taken out, the screening door 9 is opened to allow the completely screened large organic fertilizer particles to flow out, thereby improving the convenience of using the drum rotary screen.
