A dispersing assembly located below the extrusion cylinder is rotatably installed in the collection trough. A hot air blower opposite to the dispersing assembly is fixed in the collection trough.

[0007] As an improvement of the present invention: the feeding assembly includes a feeding bin vertically fixed on the conveying cylinder, the feeding bin being in communication with the inside of the conveying cylinder, a servo motor being fixed on the conveying cylinder, and a spiral shaft extending into the conveying cylinder being coaxially fixed to the output shaft of the servo motor.

[0008] As an improvement of the present invention: the reversing drive assembly includes a drive shaft rotatably mounted on the gearbox, two coaxially fixed reversing bevel gears are rotatably mounted inside the gearbox, and an incomplete bevel gear is coaxially fixed on the drive shaft, which alternately meshes with the two reversing bevel gears.

[0009] As an improvement of the present invention: the reversing drive assembly further includes a main gear fixed coaxially with the reversing bevel gear, a secondary gear meshing with the main gear, a worm gear coaxially fixed with the secondary gear, a worm wheel meshing with the worm gear, the worm wheel being fixed coaxially with the central shaft, and the central shaft being connected to the output shaft of the servo motor via a pulley mechanism.

[0010] As an improvement of the present invention: the transmission assembly includes a central gear fixed coaxially with the central shaft, and rack I and rack II are respectively meshed on both sides of the central gear. A connecting frame I is fixed between rack I and the sliding column, and a connecting frame II is fixed between rack II and the sleeve. Rack II is slidably mounted on the extrusion cylinder, and rack I is slidably mounted on the liquid collection cylinder.

[0011] As an improvement of the present invention: the side wall of the extrusion cylinder is provided with a plurality of filtrate holes I, the side wall of the filter press cylinder is provided with a plurality of filtrate holes II, a liquid collecting cylinder is fixedly sleeved on the extrusion cylinder, a rotating sleeve is rotatably installed on the liquid collecting cylinder, the rotating sleeve is rotatably sleeved on the extrusion cylinder, the rotating sleeve and the liquid collecting cylinder are connected through a connecting hole provided on the liquid collecting cylinder, and a discharge pipe is connected and installed at the bottom of the liquid collecting cylinder.

[0012] As an improvement of the present invention: a dual-shaft motor is fixed on the liquid collecting cylinder, a drive gear is driven and connected to the dual-shaft motor, an external gear ring is meshed and connected to the drive gear and fixedly sleeved on the rotating sleeve, and a scraper is fixed on the inner wall of the rotating sleeve and abuts against the outer wall of the extrusion cylinder.

[0017] In this invention, after the filter press and extrusion column have finished extruding the organic fertilizer, the filter press can move above the collection tank. The baffle can block the end of the push rod, allowing the filter press to slide relative to the push plate. This allows the dehydrated organic fertilizer to be pushed into the collection tank by the push plate. The dispersion component in the collection tank can rotate and disperse the organic fertilizer. Combined with the hot air generated by the hot air blower, the organic fertilizer is fully dehydrated. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments:

[0030] Example 1

[0031] Please see Figure 1-10 A dehydration device for microbial organic fertilizer production includes a support frame 3, an extrusion cylinder 4 fixed on the support frame 3, a collection trough 2 below the extrusion cylinder 4, a conveying cylinder 16 fixed on the extrusion cylinder 4, and a feeding through-hole 35 connecting the conveying cylinder 16 and the extrusion cylinder 4. A feeding assembly is installed on the conveying cylinder 16. A sliding column 7 is slidably installed inside the extrusion cylinder 4, a sleeve 11 is slidably sleeved on the sliding column 7, and an extrusion column 36 fixed to the sleeve 11 is slidably sleeved on the sliding column 7. A filter cylinder 10 is fixed on the sliding column 7 and slidably connected to the extrusion cylinder 4. The extrusion column 36 and the filter cylinder 10 move along the sliding column 7. The extrusion cylinder 4 is axially opposite to the filter cylinder 10. A gearbox 26 is fixed on the extrusion cylinder 4. A reversing drive assembly is installed on the gearbox 26. A central shaft 42 that rotates alternately clockwise and counterclockwise is connected to the reversing drive assembly. A transmission assembly for driving the extrusion column 36 and the filter cylinder 10 to move alternately towards and away from each other is installed on the central shaft 42. A pusher plate 39 is slidably installed inside the filter cylinder 10. A discharge assembly for driving the pusher plate 39 to slide relative to the filter cylinder 10 is installed on the filter cylinder 10. A dispersing assembly located below the extrusion cylinder 4 is rotatably installed inside the collection tank 2. A hot air blower 8 opposite to the dispersing assembly is fixed inside the collection tank 2.

[0032] This device uses a feeding assembly to transport the microbial organic fertilizer that needs to be dehydrated into the extrusion cylinder 4. The extrusion column 36 and the filter cylinder 10 are used to extrude and dehydrate the organic fertilizer that has entered the extrusion cylinder 4.

[0033] The feeding assembly includes a feeding bin 1 vertically fixed on a conveying cylinder 16, which is connected to the inside of the conveying cylinder 16. A servo motor 14 is fixed on the conveying cylinder 16, and a spiral shaft 43 extending into the conveying cylinder 16 is coaxially fixed to the output shaft of the servo motor 14. The spiral shaft 43 is driven to rotate by the servo motor 14, and the spiral shaft 43 transports the organic fertilizer inside the conveying cylinder 16 to the extrusion cylinder 4. During the reciprocating sliding process of the extrusion column 36, the extrusion column 36 can intermittently close the feed through hole 35, realizing the intermittent addition of organic fertilizer to the extrusion cylinder 4 for extrusion and dehydration. This achieves single-time small-volume extrusion and dehydration of organic fertilizer, greatly improving the dehydration effect of organic fertilizer.

[0034] The reversing drive assembly of this device includes a drive shaft 31 rotatably mounted on a gearbox 26. Two coaxially fixed reversing bevel gears 29 are rotatably mounted inside the gearbox 26. Partially bevel gears 30, which alternately mesh with the two reversing bevel gears 29, are coaxially fixed on the drive shaft 31. The reversing drive assembly also includes a main gear 25 coaxially fixed to the reversing bevel gears 29. A secondary gear 24 meshes with the main gear 25. A worm gear 27 is coaxially fixed to the secondary gear 24. A worm wheel 23 meshes with the worm gear 27. The worm wheel 23 is coaxially fixed to a central shaft 42. The central shaft 42 is connected to the output shaft of the servo motor 14 via a pulley mechanism 15.

[0035] The transmission assembly includes a central gear 28 fixed coaxially with the central shaft 42. The two sides of the central gear 28 are respectively connected to a rack I5 and a rack II13. A connecting frame I6 is fixed between the rack I5 and the sliding column 7. A connecting frame II12 is fixed between the rack II13 and the sleeve 11. The rack II13 is slidably mounted on the extrusion cylinder 4, and the rack I5 is slidably mounted on the liquid collection cylinder 19.

[0036] With the above configuration, the servo motor 14 drives the transmission shaft 31 to rotate via the belt pulley mechanism 15. The transmission shaft 31 drives the incomplete bevel gear 30 to rotate. At this time, the incomplete bevel gear 30 alternately drives the two reversing bevel gears 29 to mesh, so that the main gear 25 can rotate clockwise and counterclockwise alternately. The main gear 25 drives the auxiliary gear 24 to rotate, the auxiliary gear 24 drives the worm 27 to rotate, and the worm 27 drives the worm wheel 23 to rotate. This enables the central gear 28 to drive the central shaft 42 to rotate clockwise and counterclockwise alternately. At this time, the central shaft 42 drives the rack I5 and rack II 13 to move in opposite directions alternately. The connecting frame I6 drives the sliding column 7 and the filter cylinder 10 to reciprocate, while the connecting frame II 12 drives the extrusion column 36 to reciprocate, thereby realizing the automatic extrusion and dehydration treatment of the organic fertilizer inside the extrusion cylinder 4.

[0037] Example 2

[0038] Please see Figure 1-10 Based on Embodiment 1, additionally, several filtrate holes I37 are provided on the side wall of the extrusion cylinder 4, and several filtrate holes II38 are provided on the side wall of the filter press cylinder 10. A collection cylinder 19 is fixedly sleeved on the extrusion cylinder 4, and a rotating sleeve 17 is rotatably mounted on the collection cylinder 19. The rotating sleeve 17 is rotatably sleeved on the extrusion cylinder 4, and the rotating sleeve 17 and the collection cylinder 19 are connected through a connecting hole 32 provided on the collection cylinder 19. A discharge pipe 34 is connected to the bottom of the collection cylinder 19. A dual-shaft motor 21 is fixedly mounted on the collection cylinder 19, and a drive gear 41 is driven and connected to the dual-shaft motor 21. An external gear ring 18 is meshed and connected to the drive gear 41 and fixedly sleeved on the rotating sleeve 17. A scraper 44 is fixedly mounted on the inner wall of the rotating sleeve 17 and abuts against the outer wall of the extrusion cylinder 4.

[0039] The water generated during the dehydration process of the organic fertilizer by the extrusion column 36 and the filter press 10 enters the rotating sleeve 17 through the filter liquid hole II 38 and the filter liquid hole I 37. Then the water flows through the connecting hole 32 into the collection cylinder 19. The water squeezed out of the organic fertilizer can be easily discharged through the discharge pipe 34.

[0040] The dual-axis motor 21 can drive the drive gear 41 to rotate. The drive gear 41 drives the drive gear 41 to rotate. The drive gear 41 drives the rotating sleeve 17 to rotate through the meshing external gear ring 18. The scraper 44 on the rotating sleeve 17 rotates and scrapes the filtrate hole I37 of the extrusion cylinder 4, so that the water on the filtrate hole I37 can be scraped off into the rotating sleeve 17, promoting the accumulation of water.

[0041] The discharge assembly of this device includes a push rod 20 that slides through the filter cylinder 10. One end of the push rod 20 is fixed to the push plate 39. A return spring 40 is fixedly connected between the push plate 39 and the filter cylinder 10. A baffle 22 corresponding to the end of the push rod 20 is fixed on the collection trough 2. The dispersion assembly includes a rotating roller 9 driven by a dual-axis motor 21. Several dispersion blades 33 are fixed on the side wall of the rotating roller 9.

[0042] As the filter press cylinder 10 slides away from the extrusion cylinder 4 under the drive of the sliding column 7, the organic fertilizer inside the extrusion cylinder 4, after being squeezed and dehydrated, moves to the top of the collection tank 2. The push rod 20, as the filter press cylinder 10 moves, abuts against the baffle 22, causing the filter press cylinder 10 to slide relative to the push plate 39. That is, the push plate 39 can push out the organic fertilizer inside the filter press cylinder 10. The organic fertilizer can be automatically discharged into the collection tank 2 for collection after being squeezed and dehydrated. The dual-shaft motor 21 drives the rotating roller 9 to rotate, and the rotating roller 9 drives the dispersing blade 33 to rotate, thereby rotating and dispersing the fertilizer in the collection tank 2. At the same time, the hot air generated by the hot air blower 8 blows towards the dispersed organic fertilizer, which greatly promotes the full drying of the organic fertilizer.

[0043] In summary, the sleeve 11 and sliding column 7 in this invention move alternately towards or away from each other under the driving action of the transmission component. That is, the extrusion column 36 and the filter cylinder 10 can move alternately towards or away from each other, realizing the extrusion and dehydration treatment of the organic fertilizer inside the extrusion cylinder 4. During the reciprocating sliding process of the extrusion column 36, the extrusion column 36 can intermittently block the feed hole 35. Under the action of the feeding component, the automatic feeding effect of organic fertilizer is realized, realizing the integrated automatic operation of automatic addition, automatic extrusion and discharge of organic fertilizer, which greatly improves the dehydration effect of organic fertilizer. After the organic fertilizer is squeezed, the filter cylinder 10 and the extrusion column 36 in this invention can move the filter cylinder 10 above the collection tank 2. The baffle 22 can block the end of the push rod 20, so that the filter cylinder 10 slides relative to the push plate 39. The dehydrated organic fertilizer is pushed into the collection tank 2 by the push plate 39. The dispersion component in the collection tank 2 can rotate and disperse the organic fertilizer. Combined with the hot air generated by the hot air blower 8, the organic fertilizer is fully dehydrated.
