By setting up a series of structures, it solves the problem that people currently use drum screens to screen organic fertilizers. However, the screen holes of the drum screen are easily clogged during the screening process, thereby reducing the screening efficiency of the drum screen. In the prior art, in order to prevent the clogging of the drum screen, the screen is usually manually knocked. However, if the knocking is frequent, the screen will be damaged. In addition, this method has high labor intensity and there are certain safety hazards during the knocking process.

[0004] The present application proposes a screening and anti-blocking device for fertilizers, comprising a shell, a motor is mounted on the outside of one side wall of the shell, an output end of the motor is connected to a rotating shaft, the other end of the rotating shaft extends through the side wall of the shell to the inner cavity of the shell and is rotatably connected to the side wall of the inner cavity of the shell, a drum screen is mounted on the outer sleeve of the rotating shaft, the rotating shaft and the drum screen are connected by a plurality of support rods, a feeding mechanism is provided on the drum screen, two anti-blocking mechanisms are symmetrically provided on the outside of the shell, the other end of the anti-blocking mechanism extends through the side wall of the shell to the inner cavity of the shell and contacts the outer wall of the drum screen, and a discharging mechanism is provided at the bottom of the shell;

[0005] The anti-blocking mechanism includes a cross bar that is laterally symmetrically arranged on the outer wall of one side of the shell, the two cross bars are connected by a vertical bar, and two sliding sleeves are symmetrically provided on the vertical bar. The sliding sleeve on one side is connected to the cross bar by an electric telescopic rod, and the sliding sleeve is hinged with a moving rod at one end close to the drum screen, and the other ends of the two moving rods are jointly hinged with a moving component, the moving component is located between the two cross bars and fixedly arranged on the outer wall of the shell, and the end of the moving component close to the drum screen is connected to a connecting block, and the other end of the connecting block slides through the side wall of the shell to extend to the inner cavity of the shell and is connected to an arc plate, and an arc scraper is provided at one end of the arc plate close to the drum screen, and a brush is provided at one end of the arc scraper close to the drum screen, and the brush is in contact with the outer wall of the drum screen.

[0006] Furthermore, the moving component includes a limit block fixed to the outer wall of the shell, the limit block is located between the two cross bars, a limit groove is horizontally opened on the limit block, a moving block is slidingly arranged in the limit groove, a cylinder is arranged on the moving block, the other ends of the two moving rods are rotatably sleeved on the cylinder, and the moving block is connected to the connecting block.

It should be noted here that the curvature of the arc scraper fits the side wall of the drum screen, and the fertilizer after screening is discharged through the discharging mechanism arranged at the bottom of the shell, which solves the current problem of people commonly using drum screens to screen organic fertilizers. However, the sieve holes of the drum screen are easily blocked during the screening process, thereby reducing the screening efficiency of the drum screen. In order to prevent the clogging of the drum screen in the prior art, the screen is usually manually knocked. However, frequent knocking will cause damage to the screen, and this method is labor-intensive. There are also certain safety hazards in the knocking process.

Specifically, the fertilizer is passed into the drum screen, and the motor is started. The motor drives the rotating shaft to rotate and the drum screen to rotate to screen the fertilizer. By simultaneously starting the two electric telescopic rods, the two sliding sleeves are brought close to each other, driving the moving part to move, and at the same time driving the connecting block to move in the direction of the drum screen until the brush contacts the drum screen. At this time, during the normal operation of the drum screen, the brush sweeps the side wall of the drum screen in a circular manner to prevent the sieve holes of the drum screen from being clogged. The screened fertilizer is discharged through the discharging mechanism provided at the bottom of the shell, which solves the problem that in order to prevent the clogging of the drum screen in the existing technology, the screen is usually manually knocked.

[0022] Fertilizer processing plants generally need to perform secondary processing on fertilizers. During the secondary processing of fertilizers, organic fertilizers need to be graded and screened to remove lumps or powdered fertilizers. At present, people often use drum screens 4 to screen organic fertilizers. However, the screen holes of the drum screen 4 are easily clogged during the screening process, which reduces the screening efficiency of the drum screen 4. In order to prevent the clogging of the drum screen 4, the existing technology usually uses manual knocking of the screen. However, if the knocking is frequent, the screen will be damaged, and this method is labor-intensive. There are also certain safety hazards in the knocking process. For this reason, the present application proposes a screening and anti-blocking device for fertilizers, including a shell 1, a motor 2 is installed on the outside of one side wall of the shell 1, and the output end of the motor 2 is connected to There is a rotating shaft 3, the other end of the rotating shaft 3 extends through the side wall of the shell 1 to the inner cavity of the shell 1 and is rotatably connected to the side wall of the inner cavity of the shell 1, and a drum screen 4 is arranged on the outer cover of the rotating shaft 3.

The sliding sleeve 8 on one side is connected to the cross bar 6 by an electric telescopic rod 9. The end of the sliding sleeve 8 close to the drum screen 4 is hinged with a moving rod 10, and the other ends of the two moving rods 10 are jointly hinged with a moving component. The moving component is located between the two cross bars 6 and is fixedly arranged on the outer wall of the shell 1. The end of the moving component close to the drum screen 4 is connected to a connecting block 11. The other end of the connecting block 11 slides through the side wall of the shell 1 to extend to the inner cavity of the shell 1 and is connected to the arc plate 1 2. An arc-shaped scraper 13 is provided at one end of the arc-shaped plate 12 close to the drum screen 4. A brush 14 is provided at one end of the arc-shaped scraper 13 close to the drum screen 4. The brush 14 contacts the outer wall of the drum screen 4. Specifically, by simultaneously starting the two electric telescopic rods 9, the two sliding sleeves 8 are brought close to each other, driving the moving part to move, and at the same time driving the connecting block 11 to move toward the drum screen 4 until the brush 14 contacts the drum screen 4. When the drum screen 4 is in normal operation, the distance between the brush 14 and the outer wall of the drum screen 4 is controlled by the electric telescopic rod 9, and the side wall of the drum screen 4 is swept in a surrounding manner to prevent the screen holes of the drum screen 4 from being blocked.

[0024] Furthermore, the moving component includes a limit block 15 fixed to the outer wall of the shell 1, the limit block 15 is located between the two cross bars 6, and a limit groove 16 is horizontally opened on the limit block 15, and a moving block 17 is slidably arranged in the limit groove 16, and a cylinder 18 is provided on the moving block 17.

By starting the motor 2, the motor 2 drives the rotating shaft 3 to rotate and drives the drum screen 4 to rotate to screen the fertilizer. At this time, by simultaneously starting the two electric telescopic rods 9, the two electric telescopic rods 9 respectively push the two sliding sleeves 8 to move on the vertical rod 7, so that the two sliding sleeves 8 are close to each other. When the two sliding sleeves 8 are close to each other, When approaching each other, the two moving rods 10 will drive the moving block 17 to move in the limiting groove 16 toward the drum screen 4, and at the same time, the connecting block 11 will also move toward the direction of the drum screen 4, so that the brush 14 is in contact with the drum screen 4. It should be noted here that the end of the connecting block 11 close to the drum screen 4 is connected to the curved plate 12, and the other end of the curved plate 12 is provided with a curved scraper 13, and the end of the curved scraper 13 close to the drum screen 4 is provided with a brush 14, so the connecting block 11 will drive the curved scraper 13 to move in the direction of the drum screen 4 until the brush 14 is in contact with the drum screen 4;

[0029] When the drum screen 4 is in normal operation, the distance between the brush 14 and the outer wall of the drum screen 4 is controlled by the electric telescopic rod 9 to prevent the sieve holes of the drum screen 4 from being blocked. It should be noted that the curvature of the curved scraper 13 fits the side wall of the drum screen 4. At the same time, the curved plate 12 and the curved scraper 13 are connected by bolts 23 to realize the detachable function of the curved scraper 13. When the brush 14 is damaged to a certain extent, it is only necessary to loosen the bolts 23 and replace the curved scraper 13. It should be noted that the curved scraper 13 and the brush 14 are fixedly connected and matched. Finally, the fertilizer after screening passes through The discharge mechanism is arranged at the bottom of the shell 1 for discharge. Specifically, the fertilizer after screening will be discharged through the discharge port 21 opened at the bottom of the shell 1, and the setting of the inclined platform 22 can prevent the fertilizer from accumulating at the corner of the bottom of the shell 1, which solves the problem that people currently use the drum screen 4 to screen organic fertilizers, but the screen holes of the drum screen 4 are easily clogged during the screening process, thereby reducing the screening efficiency of the drum screen 4. In order to prevent the clogging of the drum screen 4 in the prior art, the screen is usually manually knocked, but if the knocking is frequent, the screen will be damaged, and this method is labor-intensive, and there are certain safety hazards in the knocking process.
