[0031] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 as well as Figure 7 As shown, the utility model proposes a cleaning device for bagged fertilizers, including a horizontally arranged roller conveyor belt, wherein the conveyor belt includes a base 1 and a plurality of rollers 2 installed in parallel on the base 1, with gaps between the rollers 2. The gaps are reserved by adopting the conveying mode of the rollers 2 to install a cleaning component 5 for the bottom of the bagged fertilizers, so that the cleaning can be carried out without leaving any dead corners, and it is also convenient for the fertilizer particles to slide from the gaps to the bottom.

[0033] The base 1 also includes a transmission mechanism 3 arranged in parallel on one side of the base 1, the transmission mechanism 3 drives the roller 2 to rotate, and a shell 4 is fixedly connected to the top of the roller conveyor belt, and the shell 4 is open front and back along the conveying direction. A suction mechanism 7 is also provided on the top of the shell 4, and movable doors 41 are also provided at both ends of the shell 4. The movable door 41 can be rotated and opened along the conveying direction of the conveying device. A one-way hinge is provided on the top of the movable door 41. After the movable door 41 is pushed open, after the fertilizer enters the clean space as a whole, the movable door 41 automatically falls back and closes under the action of gravity, and a clean space is formed between the shell 4 and the base 1. The shell 4 covers the base 1 to avoid dust particles flying during cleaning. The shell 4 can effectively block the flying of materials. The movable door 41 can be opened and closed. After closing, a relatively sealed space is formed, which is conducive to the suction mechanism 7 to extract dust.

[0034] A plurality of parallel cleaning components 5 and flushing components 6 are installed in the cleaning space. The cleaning components 5 and the flushing components 6 are arranged in the gap between the rollers 2. The cleaning component 5 includes four cylindrical brushes 51 arranged in a rectangular shape. The rotation axis of the cylindrical brush 51 is perpendicular to the conveying direction. Adjacent cylindrical brushes 51 are drivingly connected. The cylindrical brush 51 at the bottom of the cleaning component 5 is connected to the transmission mechanism 3, so that the transmission mechanism 3 drives the roller 2 and the cylindrical brush 51 at the bottom at the same time. The flushing component 6 is fixedly connected to the inner wall of the shell 4. The entire bagged fertilizer can be cleaned by the surrounding cylindrical brush 51. At the same time, connecting the cylindrical brush 51 to the transmission mechanism 3 can save the device for driving the cleaning component 5, and also make the control roller 2 and the cylindrical brush 51 rotate in an integrated manner. The flushing component 6 is used to finish the corners that the cleaning component 5 has not cleaned, so as to ensure that the surface of the bagged fertilizer is clean.

[0035] like Figure 1 and Figure 5 As shown, the transmission mechanism 3 includes a transmission rod 31 arranged in parallel on one side of the conveyor belt, the transmission rod 31 is perpendicular to the roller 2, and a plurality of driving gears 32 are also provided on the transmission rod 31. A driven gear 21 is provided at one end of the roller 2. The driving gear 32 and the driven gear 21 are bevel gears meshing with each other. The transmission rod 31 drives the roller 2 to rotate through the driving gear 32 and the driven gear 21. The various components are mechanically connected and powered by the transmission rod 31 to achieve an automated effect.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the cleaning assembly 5 includes a first passive gear 52 installed on one side of the cylinder brush 51, and the first passive gears 52 between adjacent cylinder brushes 51 are connected to each other through a bevel gear structure. A second passive gear 53 is also provided at the end of the cylinder brush 51 at the bottom, which is away from the first passive gear 52. The second passive gear 53 and the driving gear 32 are mutually meshing bevel gears. The transmission rod 31 drives the cylinder brush 51 to rotate through the driving gear 32 and the second passive gear 53. The diameter of the second passive gear is also smaller than that of the driven gear. Through the above structure, four mutually perpendicular and surrounding cylinder brushes 51 are connected to the cylinder brush 51 through the first passive gears 52 at both ends of the cylinder brush 51 by a bevel gear structure. Together, the transmission rod 31 drives the second passive gear 53 to rotate, thereby driving the entire cleaning assembly 5 to work. At the same time, the diameter of the second passive gear 53 is smaller than that of the driven gear 21, and the cylinder brush 51 rotates faster. The cone tip of the driving gear 32 can be adjusted to face the conveying direction of the cleaning device, and the meshing position of the driving gear 32 with the second passive gear 52 with the changed orientation can be transferred from one side of the cone surface of the second passive gear 52 to the other side, so that the rotation direction of the second passive gear 52 is changed, and then the rotation direction of the cylinder brush 51 is also changed, so that the rotation direction of the working cylinder brush 51 can clean the surface of the bagged fertilizer relative to the conveying direction of the bagged fertilizer.

[0037] like Figure 6 In another embodiment of the utility model shown, a first pulley 54 is further provided on one side of the cylinder brush 51 located at the bottom, and a second pulley 22 is further provided on the rotating shaft of a roller 2 at an adjacent position of the cylinder brush 51. The first pulley 54 is connected to the second pulley 22 by a belt 55. The diameter of the first pulley 54 is smaller than that of the second pulley 22. The roller 2 drives the first pulley 54 to rotate through the second pulley 22. By replacing pulleys of different diameters, the rotation speed of the cylinder brush 51 can be adjusted to a more suitable speed to achieve the maximum cleaning effect.

[0038] like Figure 1 As shown, a fertilizer collecting box 8 is also provided at the middle position of the bottom of the base 1, and the fertilizer collecting box 8 can collect fertilizer particles adhering to the surface of the bagged fertilizer for secondary recycling.

[0039] like Figure 1 and Figure 4 As shown, the flushing assembly 6 is an annular flushing air gun arranged on the inner wall of the shell 4. The flushing air gun is also provided with a plurality of blowing ports 61. The blowing ports 61 are inclined toward the conveying direction. By arranging the blowing ports at an angle, a larger flushing area can be obtained, thereby better cleaning the pollutants involved.

[0040] like Figure 1 and Figure 7As shown, the suction mechanism 7 includes a suction fan 71 and a filter element 72 close to the air outlet.

[0041] like Figure 7 As shown, the roller 2 is provided with anti-skid patterns 23, so that the packaged fertilizer will not slip when moving on the conveying device, thereby preventing the cleaning device from being affected.

[0042] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 as well as Figure 7 In the embodiment of the utility model, the staff transports the bagged fertilizer to the utility model through other conveying devices. Under the transportation of the roller 2, the bagged fertilizer pushes open the movable door 41, and the movable door 41 rotates upward. As the fertilizer enters, it automatically closes under the action of gravity. The cylinder brush 51 cleans the surroundings of the fertilizer, and the fertilizer particles are brushed down and fall into the fertilizer collection box 8. The air outlet 61 is connected to the high-pressure gas for secondary cleaning of the fertilizer surface. The raised dust is discharged through the suction mechanism 7, and the dust is blocked on the filter element 72. The cleaned bagged fertilizer pushes open the movable door 41 from the other end of the cleaning device and is transported out. From then on, the cleaning of the bagged fertilizer is completed.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
