[0016] The beneficial effects of the present invention are:
[0017] (1) The present invention relates to a drying device for fertilizer production, wherein a turning structure is provided inside the drying box, and a driving structure is provided inside the base. The turning structure can improve the drying efficiency of the fertilizer and reduce the caking phenomenon. The driving structure can simultaneously drive multiple drying boxes to dry the fertilizer, namely: first, a drying box is provided on the base, and the feed port on the top of the drying box is used to place fertilizer and additives. After the fertilizer is added to the drying box, the conveyor belt is driven to rotate by the transmission roller, so that the scraper provided on the surface of the conveyor belt can stir and mix the fertilizer in the drying box. Since the conveyor belt and the inner supporting mesh plate can allow the fertilizer particles to pass through, as the conveyor belt rotates, the end of the scraper always contacts the inner wall of the drying box under the action of the torsion spring, and at the same time pushes the fertilizer particles to the top side of the conveyor belt, and then falls back to the bottom side of the drying box through the conveyor belt. In this way, the fertilizer particles can be fully stirred and mixed, and good mixing can be achieved with the bottom hot air device. The drying effect is improved. At the same time, since the space on the top side of the conveyor belt is smaller than that on the top side, the scraper will appropriately squeeze the pushed fertilizer particles when it moves to the top side of the conveyor belt, thereby breaking up certain agglomerated fertilizers and reducing the phenomenon of fertilizer agglomeration. The drying boxes can be stacked. The first pulley can facilitate the stacking of the drying boxes. At the same time, when the first pulley slides to the "V"-shaped groove of the slide, it can play a certain positioning effect between the currently stacked drying boxes. The motor installed on the inside of the base is used to provide a driving effect for the rotation of the conveyor belt in the drying box. The end of the motor is connected to the first plug-in block. When the drying box is placed on the top side of the base, the second plug-in block on the bottom side of the drying box will be spliced with the first plug-in block on the base. At this time, the motor is connected to an external power supply and started to drive the connecting rod connected to the second plug-in block, and then the transmission roller is driven to rotate through the transmission effect of the worm gear. At the same time, the first plug-in block and the second plug-in block can also facilitate the accurate position of the drying boxes when stacking.
[0018] (2) The present invention relates to a drying device for fertilizer production, wherein the drying box is provided with a screening structure, and the screening structure is connected to a locking structure. The screening structure can be used to screen the fertilizer particles in the drying process, and the locking structure can be used to avoid leakage of fertilizer due to misoperation, that is, since fertilizer may have particles of different sizes, the drying boxes can be stacked to achieve drying and screening of fertilizer particles at the same time. A first sieve plate and a second sieve plate are provided at the bottom of the drying box. The first sieve plate is used to screen fertilizer particles and can be directly withdrawn for replacement. The user can judge whether it is installed in place by the engagement state between the first positioning hole and the positioning block. By selecting the first sieve plates with different apertures, fertilizer particles smaller than the aperture of the sieve plate will fall during the stirring process of the fertilizer. The user can stack multiple drying boxes according to the screening category, and select the first sieve plates with smaller apertures from the top to the bottom, and select the first sieve plate without mesh holes at the bottom. In this way, the drying box at the top will screen out larger fertilizer particles. The bottom side of the first sieve plate is provided with a second sieve plate. The second sieve plate is divided into a second through hole on the surface and a raised parallelogram part. The raised part will be embedded in the first through hole on the surface of the first sieve plate. At this time, the fertilizer particles being stirred can only pass through the mesh part and the second through hole of the second sieve plate in turn and fall to the feed port of the drying box on the bottom side until they are screened to the bottom layer. The second sieve plate is supported by the support block and the first spring. When the dried fertilizer needs to be taken out, the second sieve plate is slid so that the second through hole part of the second sieve plate coincides with the first through hole of the first sieve plate. At this time, the fertilizer can be discharged directly and discharged from the drying box on the bottom side. The drying box can obtain dried fertilizers of different particle sizes by pulling the second sieve plate in sequence, which is convenient for subsequent targeted processing of the fertilizers. An extension block is connected to the end of the second sieve plate, which can limit the sliding range of the second sieve plate. When another drying box is placed on the top of the drying box, the locking rod of the top drying box will be lifted up by the sliding plug rod of the bottom drying box, so that the locking rod is engaged with the second positioning hole of the extension block, thereby preventing the operator from pulling the second sieve plate of the top drying box, ensuring that the fertilizer particles that have been screened separately will not be mixed or leaked.
[0019] (3) The present invention relates to a drying device for fertilizer production, wherein a collecting structure is provided on the inner side of the base, and an oscillating structure is connected between the collecting structure and the base. The dried fertilizer can be collected by the collecting structure without interfering with the drying process. The oscillating structure can prevent the fertilizer from piling up during collection, that is, since the second sieve plate is relatively narrow and long as a whole, the bottom slope of the collection box may cause the fertilizer to pile up while collecting the fertilizer. When the motor is working, the transmission action of the first gear and the second gear will cause the wheel to rotate, and the slider on the side of the wheel will slide along the slit at the end of the traction rod, which will drive the traction rod to slide back and forth. At this time, the oscillating structure connected to the end of the traction rod The raised part on the side of the swing block will repeatedly push the hanging block, causing the hanging block to vibrate in the vertical direction, thereby causing the collection box to vibrate as a whole, and the fertilizer will accumulate at the bottom of the collection box. When drying the fertilizer, in order to allow the hot air generated by the hot air device on the bottom of the base to be transmitted upward from the drying box at the bottom, the user needs to release the engagement between the push rod and the side hanging rod. At this time, the bottom opening of the drying box on the bottom side allows hot air to enter, thereby achieving the fertilizer drying effect. When collecting fertilizer, the hook end of the push rod can be engaged with the hanging rod on the same side, and the fertilizer particles falling from the top drying box can flow along the inclined bottom surface of the collection box, which is convenient for collection.

After the fertilizer is added to the drying box 2, the transmission roller 303 drives the conveyor belt 301 to rotate, so that the scraper 302 provided on the surface of the conveyor belt 301 can stir and mix the fertilizer in the drying box 2. Since the conveyor belt 301 and the supporting mesh plate 307 supported on the inner side can allow the fertilizer particles to pass through, as the conveyor belt 301 rotates, the end of the scraper 302 always contacts the inner wall of the drying box 2 under the action of the torsion spring 309, and at the same time pushes the fertilizer particles to the top side of the conveyor belt 301, and then falls back to the bottom side of the drying box 2 through the conveyor belt 301, and the fertilizer particles can be repeatedly stirred. The fertilizer particles are fully turned over and stirred, and the bottom hot air device 9 is used to achieve a good drying effect. At the same time, because the space on the top side of the conveyor belt 301 is smaller than that on the top side, the scraper 302 will appropriately squeeze the pushed fertilizer particles when it moves to the top side of the conveyor belt 301, thereby breaking up certain agglomerated fertilizers and reducing the phenomenon of fertilizer agglomeration. The drying boxes 2 can be stacked and used. The first pulley 305 can facilitate the stacking between the drying boxes 2. At the same time, when the first pulley 305 slides to the "V"-shaped groove of the slide 304, it can play a certain positioning effect between the currently stacked drying boxes 2. The motor 406 installed on the inside of the base 1 is used to provide a driving effect for the rotation of the conveyor belt 301 in the drying box 2. The end of the motor 406 is connected to the first plug Connecting block 401, when the drying box 2 is placed on the top side of the base 1, the second plug-in block 403 on the bottom side of the drying box 2 will be spliced with the first plug-in block 401 on the base 1. At this time, the motor 406 is connected to the external power supply and started to drive the connecting rod 402 connected to the second plug-in block 403, and then the transmission effect of the worm gear 405 and the worm 404 drives the transmission roller 303 to rotate. At the same time, the first plug-in block 401 and the second plug-in block 403 can also facilitate the accurate position of the drying box 2 when stacking. Since the fertilizer may have particles of different sizes, the fertilizer particles can be screened while drying by stacking the drying box 2. A first sieve plate 501 and a second sieve plate 502 are provided at the bottom side of the drying box 2. The first sieve plate 501 and the second sieve plate 502 are provided. 01 is used to screen fertilizer particles and can be directly pulled out for replacement. The user can judge whether it is installed in place by the engagement state between the first positioning hole 509 and the positioning block 510. By selecting the first sieve plates 501 with different apertures, fertilizer particles smaller than the aperture of the sieve plate will fall during the stirring process of the fertilizer. The user can stack multiple drying boxes 2 according to the screening category, and select the first sieve plates 501 with smaller apertures from the top to the bottom, and select the first sieve plate 501 without mesh holes at the bottom. In this way, the drying box 2 at the top will screen out larger fertilizer particles. The bottom side of the first sieve plate 501 is provided with a second sieve plate 502. The second sieve plate 502 is divided into a second through hole 508 on the surface and a raised parallelogram part.The raised portion will be embedded in the first through hole 507 on the surface of the first sieve plate 501. At this time, the fertilizer particles being stirred can only pass through the mesh portion and the second through hole 508 of the second sieve plate 502 in turn and fall to the feed port 306 of the bottom drying box 2 until they are screened to the bottom layer. The second sieve plate 502 is supported by the support block 503 and the first spring 506. When the dried fertilizer needs to be taken out, the second sieve plate 502 is slid so that the second through hole 508 of the second sieve plate 502 coincides with the first through hole 507 of the first sieve plate 501. At this time, the fertilizer can be discharged directly, and the drying box 2 on the bottom side pulls the second sieve plate 502 in turn. 02 can obtain dried fertilizers of different particle sizes, which is convenient for subsequent targeted processing of the fertilizers. An extension block 802 is connected to the end of the second sieve plate 502. The extension block 802 can limit the sliding range of the second sieve plate 502. When another drying box 2 is placed on the top of the drying box 2, the locking rod 803 of the top drying box 2 will be lifted up by the sliding plug rod 801 of the bottom drying box 2, so that the locking rod 803 is engaged with the second positioning hole 805 of the extension block 802, thereby preventing the operator from pulling the second sieve plate 502 of the top drying box 2, ensuring that the fertilizer particles that have been screened separately will not be mixed or leaked. When drying fertilizer, in order to allow the hot air generated by the hot air device 9 on the bottom side of the base 1 to be transmitted upward from the drying box 2 at the bottom, the user needs to release the engagement between the push rod 604 and the side hanging rod 605. At this time, the bottom opening of the drying box 2 on the bottom side allows the hot air to enter, thereby achieving the drying effect of the fertilizer. When collecting fertilizer, the hooked end of the push rod 604 can be engaged with the hanging rod 605 on the same side, and the fertilizer particles falling from the drying box 2 on the top side can flow along the inclined bottom surface of the collection box 602, which is convenient for collection. Since the second sieve plate 502 is relatively narrow and long as a whole, the bottom inclined surface of the collection box 602 is While collecting fertilizer, it may accumulate. When the motor 406 is working, the transmission action of the first gear 701 and the second gear 702 causes the wheel disc 703 to rotate. The slider 705 on the side of the wheel disc 703 slides along the slit at the end of the traction rod 704, driving the traction rod 704 to slide back and forth. At this time, the raised part on the side of the vibration block 706 connected to the end of the traction rod 704 repeatedly pushes the suspension block 603, causing the suspension block 603 to vibrate in the vertical direction, thereby vibrating the entire collection box 602, causing the fertilizer to accumulate at the bottom of the collection box 602.
