[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0021] At present, when screening microbial fertilizers, vertical vibration screening is mostly used for screening. However, this screening method can easily cause clogging of the screening equipment, and continuous vibration can easily shake off the formed fertilizer, which will affect the subsequent collection of the fertilizer and bring inconvenience to the subsequent processing of the staff.

[0022] In view of this, the utility model provides a screening device for compound microbial fertilizer. Through the cooperation of the box, the screening device and the support plate, the fertilizer can be screened in an arc motion, which can greatly reduce the accident of blockage of the screening device and effectively avoid the phenomenon of fertilizer being shaken and scattered due to high-frequency vibration. Therefore, the production quality of the fertilizer can be guaranteed, and the subsequent processing operations of the fertilizer are also facilitated, thus bringing convenience to the staff.

[0023] Example 1: By Figure 1 、 2, 3 and 4 show that a screening device for a compound microbial fertilizer comprises a box body 1, support plates 5 are rotatably connected to both sides of the box body 1, and a screening structure 2 is provided on the side of the two support plates 5 close to each other, and the screening structure 2 comprises: a filter screen 21, mounted on the inner wall of the box body 1; a first servo motor 22, detachably connected to one side of the support plate 5, and an output end detachably connected to one side of the box body 1; a controller 23, detachably connected to the outer wall of the support plate 5 close to the side of the first servo motor 22; a stirring device 24, arranged inside the box body 1; wherein the first servo motor 22 drives the box body 1 to rotate in an arc along the outer wall of the support plate 5, and the stirring device 24 stirs the fertilizer when the box body 1 moves;

[0024] In the specific implementation process, it is worth noting that the mesh number of the filter 21 is not limited, as long as it meets the use requirements. The models of the first servo motor 22 and the controller 23 are not limited, as long as they meet the use requirements. The staff can adjust the rotation angle of the first servo motor 22 during operation through the controller 23, thereby controlling the rotation angle of the box 1. This is a well-known technology, so it will not be described in detail. Those skilled in the art should have a broad understanding of it.

[0025] Furthermore, the stirring device 24 includes: two brackets 241, which are respectively installed on the top of the two support plates 5; a stirring rod 242, which is installed below the two brackets 241; wherein, when the box body 1 moves, the stirring rod 242 stirs the fertilizer inside the box body 1;

[0026] In the specific implementation process, it is worth noting that when the box body 1 moves, since the stirring rod 242 is in a stationary state, the fertilizer inside the box body 1 can be stirred by the stirring rod 242 to improve the efficiency and quality of its screening;

[0027] Specifically, when using the screening device for compound microbial fertilizer, when the fertilizer enters the interior of the box 1, the staff turns on the external power supply of the first servo motor 22. At this time, the first servo motor 22 can drive the box 1 to rotate along the outer wall of the support plate 5. Since the stirring rod 242 is in a stationary state, the fertilizer inside the box 1 can be stirred as the box 1 moves, and then the fertilizer can be screened through the filter 21.

[0028] Example 2: By Figure 1 and 4As can be seen, a crushing device 3 is provided above the box body 1. The crushing device 3 includes: a top box 31, which is installed at the ends of the two brackets 241; two second servo motors 34, which are both detachably connected to the outer wall of the top box 31; two crushing rollers 32, which are rotatably connected to the inner wall of the top box 31 through sealed bearings and are detachably connected to the output ends of the two second servo motors 34; two guide plates 33, which are both installed above the top box 31; wherein the second servo motor 34 drives the crushing rollers 32 to crush the fertilizer guided by the guide plates 33;

[0029] In the specific implementation process, it is worth noting that the model of the second servo motor 34 is not limited, as long as it meets the use requirements. The second servo motor 34 can drive the crushing roller 32 to rotate. At this time, the agglomerated fertilizer can be crushed by the cooperation of the two crushing rollers 32.

[0030] Specifically, when using the screening device for compound microbial fertilizer, the staff pours the fertilizer into the crushing device 3, and then turns on the external power supply of the second servo motor 34. The second servo motor 34 can drive the crushing roller 32 to rotate. At this time, as the two crushing rollers 32 rotate, the fertilizer can be crushed.

[0031] Example 3: By Figure 1 and 2 As can be seen, a collecting device 4 is provided below the box body 1. The collecting device 4 includes: a collecting box 41, which is provided below the box body 1; two connecting plates 42, which are respectively installed on both sides of the collecting box 41 and are respectively fixed to the outer walls of the two supporting plates 5; a processing device 43, which is provided on both sides of the interior of the collecting box 41; wherein the processing device 43 is capable of drying the fertilizer collected inside the collecting box 41;

[0032] In the specific implementation process, it is worth noting that the connecting plate 42 can connect and fix the collection box 41 to the support plate 5, and the front and rear sides of the collection box 41 have protruding parts, the protruding height of which can be selected according to actual use requirements, in order to prevent the fertilizer from being thrown out of the collection box 41 due to inertia;

[0033] Furthermore, the processing device 43 includes: a plurality of mounting racks 431, each mounted on the inner wall of the collection box 41; two conduits 432, each mounted on the inner wall of the plurality of mounting racks 431; wherein the external gas supply device can transport gas through the conduits 432 and spray it toward the fertilizer, and finally dry the fertilizer;

[0034] In the specific implementation process, it is worth noting that the conduit 432 is connected to the external air supply device, and the external air supply device can transport gas to the inside of the conduit 432, and then blow the air to the surface of the fertilizer through the conduit 432, thereby accelerating the air flow rate on the surface of the fertilizer, so as to dry the fertilizer. There is no restriction on the equipment selection of the external air supply device, as long as it meets the use requirements. When using it, it should be noted that the wind force should not be too strong, thereby avoiding blowing the fertilizer out of the collection box 41. The wind force can be selected according to the use requirements and is not limited here, so as to meet the technical characteristics of this case.

[0035] Specifically, based on the above-mentioned embodiments 1 and 2, when the fertilizer enters the interior of the collection box 41, if the humidity of the fertilizer is high, the external power supply of the external air supply device can be turned on. At this time, the external air supply device can transport air to the interior of the conduit 432, and then blow it toward the surface of the fertilizer through the conduit 432, and the fertilizer can be dried.
