The organic fertilizer screening device with the quickly-disassembled and assembled screen provided by the invention has the following working principle:
firstly, all the limit plates 43 are respectively pulled outwards, the limit plates 43 slide in the chutes 42, the sliding plates 48 slide relative to the limit plates 43 due to the sliding plates 48 being blocked by the inner walls of the protection boxes 41, the sliding plates 48 slide in the guide rails 49, finally, the limit blocks 44 at one ends of the limit plates 43 abut against the inner walls of the sorting frames 23, then, the four corners of the frame 31 are clamped in the baffles 29, so that the outer side walls of the frame 31 abut against the baffles 29, then, the limit plates 43 are pushed inwards, the limit plates 43 slide in the sorting frames 23, finally, the limit plates 43 are inserted into the top surfaces of the frame 31, the limit plates 43 abut against the top surfaces of the frame 31, and the limit blocks 44 at the other ends of the limit plates 43 abut against the side walls of the protection boxes 41, at this time, the screw rods 45 are rotated, the bottom end of the screw 45 and the pressing plate 46 rotate relatively and simultaneously push the pressing plate 46 to move downwards, the pressing plate 46 abuts against and pushes the limiting plate 43 downwards, the limiting plate 43 tightly presses the frame 31 until the screw 45 cannot rotate, meanwhile, the limiting plate 43 pushes the sliding plate 48 downwards, the sliding plate 48 compresses the second spring 47, and the second spring 47 shortens; switch on external power source, start two vibrating motor 24, vibrating motor 24 drives letter sorting frame 23 vibrations, vibrations pass through supporting sleeve 22 transmits to on the first spring 21, first spring 21 will constantly extend and shorten, make letter sorting frame 23 can keep high frequency vibrations, can drive while letter sorting frame 23 vibrations frame 31 vibrations together, will need the fertilizer of screening to pour into immediately in the storage hopper 51, fertilizer follows the drain hole 52 of storage hopper 51 bottom evenly drops in screening structure 3, vertical iron wire 33 with the screen cloth that horizontal iron wire 34 formed will satisfy the fertilizer granule of specified size and leak, and the fertilizer that the granule is big is stayed on the screen cloth, reaches the fertilizer of specified size and falls into in letter sorting frame 23, through the vibrations of letter sorting frame 23, no matter be vertical iron wire 33 with the large granule fertilizer more than the screen cloth that horizontal iron wire 34 formed or in the letter sorting frame 23 Qualified fertilizer on the bottom surface moves downwards, finally the qualified fertilizer is discharged through the discharge hole 27 at the lower end of the sorting frame 23 and enters other storage devices through the discharge hopper 28, while unqualified fertilizer is separated from the screening structure 3 and enters the material distribution channel 26, and the unqualified fertilizer is conveyed to the side leakage pipe 25 by utilizing the inclined inner wall of the material distribution channel 26 and is discharged through the side leakage pipe 25; if the screen formed by the longitudinal iron wires 33 and the transverse iron wires 34 is blocked, the gear 32 can be rotated, the gear 32 drives the first transmission gear 36 inside the frame 31 to rotate, so that the belt pulley 37 on the surface of the frame rotates synchronously, the belt pulley 37 drives the belt 38 to rotate, the belt 38 drives all the belt pulleys 37 to rotate, further all the transmission gears 36 rotate, each longitudinal iron wire 33 fixedly connected with the transmission gear 36 also rotates synchronously, the longitudinal iron wires 33 drive a plurality of shifting pieces 35 on the side walls of the longitudinal iron wires 33 to rotate, the shifting pieces 35 continuously penetrate through the screen holes formed by the longitudinal iron wires 33 and the transverse iron wires 34 in the rotating process, fertilizer particles clamped in the screen holes are pushed upwards, and the fertilizer particles are returned to the screen formed by the longitudinal iron wires 33 and the transverse iron wires 34 again, and convey these fertilizer granules into the said distributing chute 26 by shaking, and then out of the machine; after the screening is finished, the vibration motor 24 is turned off, the sorting frame 23 stops vibrating, and the first spring 21 also stops deforming; when taking off the screening structure 3, at first the antiport the screw rod 45, the screw rod 45 drives the clamp plate 46 rises, the limiting plate 43 loses the conflict of clamp plate 46 under the promotion of second spring 47, slide 48 with limiting plate 43 rises together, limiting plate 43 no longer conflicts the frame 31, then outwards draw limiting plate 43, limiting plate 43 is in slide in the spout 42, because slide 48 is blockked by protection box 41 inner wall, consequently slide 48 with limiting plate 43 relative slip, slide 48 is in slide in the guide rail 49, finally the stopper 44 of limiting plate 43 one end conflicts the inner wall of letter sorting frame 23, takes out next the screening structure 3, will at last limiting plate 43 pushes back.
Compared with the prior art, the organic fertilizer screening device with the quickly-disassembled and assembled screen has the following beneficial effects:
the invention provides an organic fertilizer screening device with a quickly-disassembled screen, which is characterized in that the installation position of a screening structure 3 is limited through a baffle 29, then the movement of the screening structure 3 is flexibly limited through the transverse sliding of a limiting plate 43, and the limiting plate 43 is pushed to descend by a screw 45, so that the limiting plate 43 compresses a frame 31; the gears 32 are used for driving the transmission gears 36 to rotate, so that each longitudinal iron wire 33 is controlled to rotate, the poking pieces 35 are driven to penetrate through the sieve meshes, large-particle fertilizers in the sieve meshes are pushed out upwards, unqualified fertilizers in the sieve meshes are cleaned, the efficient sorting capacity of the screening structure 3 is guaranteed, and meanwhile the problems that the unqualified fertilizers penetrate through the sieve meshes and fall into the sorting frame 23 to cause incomplete fertilizer sorting and the like can be avoided.
