Wherein, be able to maintain under the elastic force of second spring 42 shift(ing) ring 41 be close to 22 outer wall of drainage conduit, moving cylinder 43 with Installation 231 inner wall of lid is close to and 43 sets of moving cylinder outside the first driven rod 44 and the second driven rod 45.

It can be driven to realize multiple flabellums 232 only by cylinder 211, be provided in installation lid 231 for swingle 46 driving chambers protruded into；

Each mounting portion 233 includes installation part 47, column 48, pull rod 49, sleeve 400, third spring 401 and connection Block 402, swingle 46 are fixed to an installation part 47 away from 44 one end of the first driven rod, and installation part 47 is mounted on driving with being able to rotate On cavity wall, swingle 46, which is located on the edge of driving chamber inner end, is fixed with a column 48, and column 48 passes through 49 one end of pull rod, Pull rod 49 can be rotated relative to column 48, and 49 other end of pull rod stretches in 400 one end of a sleeve, and 400 other end of sleeve is fixed to On one link block 402, the mobile direction of 49 relative sleeve 400 of pull rod is vertical with swingle 46, and pull rod 49, which passes through, third spring 401,401 one end of third spring and sleeve 400 are fixed, and 401 other end of third spring and pull rod 49 are fixed；

Driving mechanism includes two cylinders 211 and two drive rods 212, all link blocks 402 positioned at 22 side of drainage conduit It is all secured to a drive rod 212, all link blocks 402 positioned at 22 other side of drainage conduit are all secured to another drive rod 212, often One drive rod 212 is all secured on the piston rod of a cylinder 211, and each cylinder 211 is mounted on installation lid 231 and each cylinder 211 piston rod stretches in driving chamber, and the telescopic direction and pull rod 49 and swingle 46 of each cylinder 211 are vertical.

It accommodates and is stood on ground outside cylinder 11 by stand 6, vibrating motor 5 is installed in stand 6.Biological organic fertilizer from Feed hopper 18 enters in second mounting ring 17, and sieve 16 blocks the particle beaten of diameter in second mounting ring 17, when needing to sieve When mitogenetic organic fertilizer, start vibrating motor 5, vibrates, make on the ground so that accommodating cylinder 11, stand 6 and vibrating motor 5 It obtains fine particle in biological organic fertilizer to expose from below, particle is big to be trapped in second mounting ring 17.

The working principle of the present embodiment：

When needing replacing sieve 16, firstly, knockout screw；Then, 43 lid 14 of moving cylinder, so that cover 14 is from vertical side It is upwardly separated from and accommodates cylinder 11, realize mobile bar 151, second mounting ring 17 and sieve 16 etc. is exposed outside；After again, squeeze Mobile bar 151 is pressed, so that mobile bar 151 is close to second mounting ring 17, the first spring 153 is further compressed, and bayonet lock 152 is de- From the first mounting ring 13, can be moved together from top by mobile bar 151, the first spring 153, second mounting ring 17 and sieve 16 It walks, realizes the disassembly of sieve 16, can be shifted the coarse granule in second mounting ring 17 after disassembly, also sieve 16 easy to clean With replacement sieve 16.When needing to install sieve 16, firstly, keeping mobile bar 151 close to second mounting ring 17, the first peace is avoided Fill the movement that ring 13 hinders bayonet lock 152；Then, by mobile bar 151, the first spring 153, second mounting ring 17 and sieve 16 1 It rises and is inserted into the first mounting ring 13, so that support ring 12 is close to 17 bottom surface of second mounting ring, while keeping the first mounting ring Jack on 13 is aligned with bayonet lock 152；After again, mobile bar 151 is discharged, under the elastic force of the first spring 153, keeps bayonet lock 152 It is inserted into the first mounting ring 13, realizes the placement of sieve 16；After again, by cover 14, upper cover is accommodating cylinder 11 from vertical direction On, so that cover 14 is passed through by mobile bar 151, second mounting ring 17 is pressed in support ring 12 by cover 14；Finally, screwing in spiral shell Nail, so that cover 14 is connect by screw with cylinder 11 is accommodated.

When switching mechanism 23 works normally, while starting two synchronous cylinders 211, there is cylinder 211 in only one end certainly It can also be in the elongation of 211 piston rod of cylinder, each link block 402 drives pull rod 49 mobile, and pull rod 49 drives swingle 46 Rotation, what is played due to flabellum 232 is switching function, the closing of drainage conduit 22 when leaf body 31 is located at horizontal plane, when leaf body 31 The aperture of drainage conduit 22 is maximum when on vertical direction, thus flabellum 232 only need to rotate back and forth 90 degree can, therefore will not Because the presence of installation part 47 hinders pull rod 49 that swingle 46 is driven to rotate, when swingle 46 rotates, column 48 has in 49 side of pull rod Upward componental movement, and the relative motion of pull rod 49 and sleeve 400 can decompose the movement of swingle 46, therefore can guarantee to fan The opening and closing work of leaf 232 can be normally carried out.When rotation, mounting rod 32 is cylinder, avoids mounting rod 32 and mounting groove inner wall It rubs and damages, since the first driven rod 44 and the second driven rod 45 are cuboid, then swingle 46 drives by first Bar 44 drives moving cylinder 43 to rotate, and moving cylinder 43 drives the rotation of the second driven rod 45, and moving cylinder 43 is located at 44 He of the first driven rod When second driven rod 45 is outer, moving cylinder 43 cannot be rotated relative to the first driven rod 44 and the second driven rod 45.

When needing to dismantle flabellum 232, firstly, protruding into below installation lid 231, moving cylinder 43 is slided, so that moving cylinder 43 is mobile to the second driven rod 45, and final moving cylinder 43 is detached from the first driven rod 44, and second spring 42 is compressed, and keeps each leaf The moving cylinder 43 at 31 both ends of body is detached from the first driven rod 44；Then, mobile flabellum 232, the second driven rod 45, shift(ing) ring 41, Second spring 42 and moving cylinder 43, realize the disengaging of flabellum 232 and the first driven rod 44 and swingle 46, and disassembly is completed. When needing to install flabellum 232, firstly, the moving cylinder 43 at 232 both ends of flabellum is kept to be close to mounting rod 32, the first drive is avoided Bar 44 hinders the movement of moving cylinder 43, keeps this state；After again, mobile flabellum 232, the second driven rod 45, shift(ing) ring 41, second Spring 42 and moving cylinder 43, so that moving cylinder 43 is aligned with the first driven rod 44, mounting rod 32 is located in its mounting groove；Most Afterwards, moving cylinder 43 is discharged, so that moving cylinder 43, under 42 elastic force of second spring, holding is covered to be driven in the first driven rod 44 and second Outside bar 45, and then realize installation.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
