Therefore, it is necessary to control the size of the particulate matter processed in fertilizer production to realize the separation of materials with different particle sizes. And the traditional rotary sieve is prone to blockage during use, which leads to a decrease in its screening and filtering efficiency. Therefore, a cleaning device also needs to be set up during use.

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0026] The present utility model provides as Figures 1-5A cylindrical rolling sieve for fertilizer production as shown, includes a screening cylinder 1, a fixed plate 2 and a driven gear 3. One end of the screening cylinder 1 is fixedly connected with the driven gear 3. A fixed plate 2 is arranged on the side of the driven gear 3 away from the screening cylinder 1. A baffle 4 is arranged at the end of the screening cylinder 1 away from the driven gear 3. A rotating assembly 5 is installed at the top of the side wall of the baffle 4 close to the screening cylinder 1. At one end of the screening cylinder 1 for screening, away from the driven gear 3, there is a central cylinder 101. At one end of the central cylinder 101 away from the screening cylinder 1, there is a connecting cylinder 102. Filter holes 103 are opened on the outer walls of the screening cylinder 1, the central cylinder 101 and the connecting cylinder 102 close to the driven gear 3. The diameters of the filter holes 103 on the side walls of the screening cylinder 1, the central cylinder 101 and the connecting cylinder 102 are different.

[0027] As Figure 3 , Figure 4 shown, at the corresponding positions of the outer wall of the driving rod 202 and the side walls of one ends of the central cylinder 101 and the connecting cylinder 102, there are respectively rotatably connected with filter net plates 104. The outer wall of the filter net plate 104 at one end of the central cylinder 101 is fixed to the inner wall of the screening cylinder 1. The filter net plate 104 at one end of the connecting cylinder 102 is fixed to the inner wall of the connecting cylinder 102. The diameters of the inner parts of the two filter net plates 104 are different. Since the diameters of the filter holes 103 on the outer walls of the screening cylinder 1, the central cylinder 101 and the connecting cylinder 102 are different, thus materials with multiple different particle sizes do not mix with each other, which is convenient for separating them.

[0028] As Figure 2 , Figure 5 shown, the top of the driven gear 3 for rotation is meshed and connected with a driving gear 301. A transmission rod 303 is arranged through the inner part of the driving gear 301 close to the baffle 4. One end of the transmission rod 303 is rotatably connected with the baffle 4 through a bearing. One end of the connecting cylinder 102 is rotatably connected with one side wall of the baffle 4 through a rotating shaft. And a feed inlet 401 is opened at a position inside the baffle 4 close to the inside of the connecting cylinder 102.

[0029] During use, fertilizers can be conveniently poured into the interior of the connecting cylinder 102 through the feeding port 401. Then, the rotating motor 302 is started, driving the driving gear 301 to rotate, which in turn causes the driven gear 3 to rotate, driving the screening cylinder 1 to rotate. At the same time, the screening cylinder 1 drives the central cylinder 101 to rotate through the filter screen plate 104, and the central cylinder 101 drives the connecting cylinder 102 to rotate through the filter screen plate 104, thus realizing the rotation of the material. Through the filter holes 103 on the outer wall of the connecting cylinder 102 and the filter screen plate 104, granular materials can be filtered into the interior of the central cylinder 101. Meanwhile, when the central cylinder 101 rotates, smaller particles can also be filtered into the interior of the screening cylinder 1 through the filter holes 103 and the filter screen plate 104. Finally, through the rotation of the screening cylinder 1, smaller materials are filtered again by the filter holes 103 for separation. Since the diameters of the filter holes 103 on the outer walls of the screening cylinder 1, the central cylinder 101, and the connecting cylinder 102 are different, materials of multiple different particle sizes do not mix with each other, facilitating their separate packaging and processing.

[0030] As Figure 3 , Figure 5 shown, the rotating assembly 5 for cleaning includes a rotating rod 501 and a cleaning roller 502. Cleaning rollers 502 are provided at the top of the outer walls of the central cylinder 101 and the connecting cylinder 102. The interior of the cleaning roller 502 is eccentrically fixed to the rotating rod 501. Belt pulleys 503 are fixedly connected to one end of the rotating rod 501 and the transmission rod 303 close to the baffle 4. The outer walls of the cleaning rollers 502 are respectively in contact with the tops of the central cylinder 101 and the connecting cylinder 102. The multiple belt pulleys 503 are drivingly connected through a transmission belt 504. One end of the rotating rod 501 is rotatably connected to the baffle 4 through a bearing. By driving the transmission belt 504 to rotate through the belt pulley 503, the belt pulley 503 at one end of the rotating rod 501 is driven by the transmission belt 504, and then the cleaning roller 502 is driven to rotate through the rotating rod 501.

[0031] As Figure 1 , Figure 5 shown, a driving motor 201 is installed at the position near the center of the driven gear 3 on the fixed plate 2. The power output end of the driving motor 201 passes through the fixed plate 2 and the interior of the driven gear 3 and is connected to a driving rod 202. Stirring rods 203 are provided at the corresponding positions on the outer wall of the driving rod 202. An installation frame is provided at the bottom of the fixed plate 2. A rotating motor 302 is fixedly installed on one side wall of the top of the fixed plate 2 away from the transmission rod 303. The power output end of the rotating motor 302 is fixed to the transmission rod 303. The diameter of the driving gear 301 is smaller than that of the driven gear 3.

[0032] During use, the drive motor 201 can also be started, so that the drive rod 202 rotates to drive the stirring rod, realizing the rotation of the material to improve the filtration efficiency. And when the transmission rod 303 rotates, it can drive the transmission belt 504 to rotate through the pulley 503, so that the transmission belt 504 drives the pulley 503 at one end of the rotating rod 501, and then drives the cleaning roller 502 to rotate through the rotating rod 501. At the same time, since the diameters of the driven gear 301 and the driving gear 3 are different, the different rotations of the cleaning roller 502 and the central cylinder 101 and the connecting cylinder 102 are realized. Then, through the rotation of the cleaning roller 502, it intermittently fits and presses against the central cylinder 101 and the connecting cylinder 102, which can effectively clean the materials blocked inside the filter holes 103 and improve the filtration efficiency.

[0033] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
