Detailed implementation manners

[0016] The following will further elaborate on this application in conjunction with the Figure 1-3 accompanying drawings.

[0017] An embodiment of this application discloses a screening device for processing nursery substrate. Refer to Figure 1-3, including a bottom plate 11, a lower movable frame 31, an upper movable frame 32 and two C-shaped rods 41. Columns 12 are welded to both ends of the top of the bottom plate 11. A storage box 2 is movably placed in the middle of the top end of the bottom plate 11. The storage box 2 can be used to collect the screened matrix. The lower movable frame 31 is located on top of the storage box 2. A driving assembly 5 for driving the lower movable frame 31 to rotate is arranged on one side of one of the bottom plates 11. The driving assembly 5 is composed of a driving motor 51 and a rotating rod 52. Through holes are formed on one side of both columns 12. The driving motor 51 is fixedly installed on one side of one of the columns 12. The power shaft of the driving motor 51 is rotatably inserted into the inside of one of the through holes. There are two rotating rods 52. The two rotating rods 52 are respectively welded to the other two sides of the lower movable frame 31. The two rotating rods 52 are respectively rotatably inserted into the inside of the two through holes to support the lower movable frame 31. One of the rotating rods 52 is welded to the end of the power shaft of the driving motor 51. When the power shaft of the driving motor 51 drives the rotating rod 52 to rotate, the rotating rod 52 can drive the lower movable frame 31 to rotate. The upper movable frame 32 is located on top of the lower movable frame 31. Filter meshes 33 are welded to the inner bottom of the lower movable frame 31 and the inner top of the upper movable frame 32. By placing the matrix to be screened inside the lower movable frame 31 and then movably penetrating the two ends of the two C-shaped rods 41 through the two corners on one side of the lower movable frame 31 and the two corners on one side of the upper movable frame 32 respectively, the docked lower movable frame 31 and upper movable frame 32 can be limited. At the same time, the lower movable frame 31, the upper movable frame 32 and the two filter meshes 33 cooperate to cover the matrix. Fixed blocks 42 are welded to the two corners on the other side of the lower movable frame 31. One end of the top of each of the two C-shaped rods 41 is threadedly penetrated by a bolt 43. The two bolts 43 are respectively threadedly penetrated through the two fixed blocks 42 to fix the two C-shaped rods 41 and the two fixed blocks 42. Then when the power shaft of the driving motor 51 drives the rotating rod 52 to rotate, the rotating rod 52 drives the lower movable frame 31 to rotate and roll, and the lower movable frame 31 drives the upper movable frame 32 to rotate and roll, so that the matrix rolls inside the lower movable frame 31 and the upper movable frame 32, and the matrix with smaller particles is screened out from inside the two filter meshes 33 into the storage box 2.

[0018] Referring to Figure 1 and Figure 2, handles 6 are welded to the other two sides of the upper movable frame 32. After the screening of the substrate is completed, the upper movable frame 32 is rotated below the lower movable frame 31, and the large-particle impurities will fall into the interior of the upper movable frame 32. One worker holds the two handles 6, and then another worker rotates the two bolts 43 to separate them from the two U-shaped rods 41 and the two fixing blocks 42, and pulls the two U-shaped rods 41 to separate them from the lower movable frame 31 and the upper movable frame 32. At this time, the upper movable frame 32 can be separated from the lower movable frame 31, so as to lift the upper movable frame 32 from the bottom of the lower movable frame 31, and then process the large-particle substrate.

[0019] Refer to Figure 1 and Figure 2 , two fixing rods 71 are welded to the edge of one side of the storage box 2. A holding rod 72 is welded to one side of one of the fixing rods 71, and one end of the holding rod 72 is welded to one side of the other fixing rod 71. The two fixing rods 71 cooperate to support the holding rod 72. Hold the holding rod 72 and apply a pulling force to it, then the storage box 2 can be pulled away from the bottom plate 11.

[0020] The implementation principle of a screening device for processing nursery substrates in an embodiment of the present application is as follows: When in use, pour the substrate into the lower movable frame 31, and then place the upper movable frame 32 above the lower movable frame 31. At the same time, the two ends of the two U-shaped rods 41 are respectively movably penetrated through the two corners on one side of the lower movable frame 31 and the two corners on one side of the upper movable frame 32. Then, use the two bolts 43 to fix the two U-shaped rods 41 to the two fixing blocks 42. Then, start the driving motor 51. When the power shaft of the driving motor 51 drives the rotating rod 52 to rotate, the rotating rod 52 drives the lower movable frame 31 to rotate and roll, and the lower movable frame 31 drives the upper movable frame 32 to rotate and roll, so that the substrate rolls inside the lower movable frame 31 and the upper movable frame 32, and the substrate with smaller particles is screened out from the inside of the two filter meshes 33 into the storage box 2;

[0021] After the screening is completed, rotate the upper movable frame 32 below the lower movable frame 31, and the large-particle impurities will fall into the interior of the upper movable frame 32. One worker holds the two handles 6, and then another worker rotates the two bolts 43 to separate them from the two U-shaped rods 41 and the two fixing blocks 42, and pulls the two U-shaped rods 41 to separate them from the lower movable frame 31 and the upper movable frame 32. At this time, the upper movable frame 32 can be separated from the lower movable frame 31, so as to lift the upper movable frame 32 from the bottom of the lower movable frame 31, and then process the large-particle substrate.
