[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

[0031] See also Figure 1-8 A granulation device provided by an embodiment of the present invention includes a central axis 1, a stirring chamber 2 and a collecting chamber 3. The upper end of the central axis 1 is rotatably arranged in the stirring chamber 2, the collecting chamber 3 is arranged below the stirring chamber 2, a grinding plate 4 is arranged on the bottom surface of the stirring chamber 2, and a plurality of extrusion holes 5 are arranged on the grinding plate 4. The granulation device also includes: a sleeve 6, which is movably sleeved on the upper end of the central axis 1 and can rotate synchronously with the central axis 1; a plurality of extrusion rollers 7 are arranged, which are rotatably connected to the sleeve 6 and are evenly distributed in the stirring chamber 2 with the central axis 1 as the axis; a linkage component, which is used to link the extrusion rollers 7 to actively rotate when the central axis 1 rotates.

[0032] Specifically, the mixing bin 2 and the collecting bin 3 are connected up and down in a cylindrical shape. A feed hopper is arranged at the upper end of the mixing bin 2, a discharge port is arranged on the side wall of the collecting bin 3, and a transmission bin is arranged at the lower end of the collecting bin 3. The side wall of the transmission bin is connected to a power bin, and the input end of the power bin is connected to a motor to provide power. A distribution cabinet is arranged on the power bin, and a control circuit is integrated in the distribution cabinet. The transmission bin, the power bin and the motor are arranged on the same base, and the central axis 1 can be switched forward and reverse under the control of the circuit. The grinding plate 4 separates the mixing bin 2 from the collecting bin 3; the extrusion holes 5 are evenly distributed on the grinding plate 4 to ensure uniform extrusion of the material. The set 6 is coaxial with the central axis 1; the extrusion rollers 7 are preferably 2-4; preferably, the outer wall of the extrusion roller 7 can be provided with rib grooves to improve the rolling and discharging efficiency; the outer wall of the set 6 is fixedly provided with a core shaft 8, and the extrusion roller 7 is rotatably connected to the core shaft 8. When the central axis 1 rotates, the linkage assembly is passively triggered to make the extrusion roller 7 rotate actively. In actual use of this technical solution, after the production raw materials are added into the mixing bin 2, the central axis 1 is driven by the servo system to rotate, and then the extrusion rollers 7 are driven to rotate through the kit 6 to stir the production raw materials in the mixing bin 2. At the same time, the extrusion rollers 7 actively rotate under the action of the linkage assembly to cooperate with the grinding plate 4 to rub and squeeze the production raw materials, thereby fully mixing the production raw materials, crushing the production raw materials, and making the production raw materials tightly blended, which greatly improves the quality of organic fertilizer products.

[0033] Compared with the prior art, a granulating device proposed in an embodiment of the present invention can be provided with a linkage component, when the central axis 1 drives each squeezing roller 7 to rotate through the set 6 to stir the production raw materials in the mixing bin 2, the squeezing roller 7 can be linked to actively rotate to cooperate with the grinding plate 4 to rub and squeeze the production raw materials, thereby fully mixing the production raw materials, crushing the production raw materials, and making the production raw materials tightly blended, thereby greatly improving the quality of the organic fertilizer product.

[0034] As the preferred technical scheme of this embodiment, the linkage assembly includes a linkage bin 9 arranged on the side wall of the mixing bin 2, a stop sleeve 10 is arranged on the inner wall of the mixing bin 2 for rotation, the rotating shaft of the extrusion roller 7 rotates through the stop sleeve 10 to extend into the linkage bin 9 and is connected to a gear 11 for transmission, the gear 11 is rotatably connected to the stop sleeve 10, and an inner gear ring 12 matching the gear 11 is arranged in the linkage bin 9. Specifically, the linkage bin 9 is arranged in the form of an annular protrusion on the outside of the mixing bin 2, and the annular structure of the linkage bin 9 is coaxial with the central axis 1; the stop sleeve 10 fits the inner wall of the mixing bin 2 to block the linkage bin 9 and prevent the material in the mixing bin 2 from entering the linkage bin 9; the axial direction of the gear 11 is arranged parallel to the axial direction of the central axis 1; the inner gear ring 12 is arranged on the inner wall of the linkage bin 9, and the axial direction is parallel to the axial direction of the central axis 1; the inner gear ring 12 is extended in the axial direction, so that the gear 11 can move axially within a certain range of height and remain in meshing with the inner gear ring 12. In actual use of the present technical solution, when the central shaft 1 rotates in a certain direction, it drives the set 6 to rotate synchronously, the set 6 drives each squeezing roller 7 to rotate, the squeezing roller 7 drives the stopper sleeve 10 to rotate, the stopper sleeve 10 drives the gear 11 thereon and the inner gear ring 12 to transmit, and then drives the rotating shaft of the squeezing roller 7 to rotate, the squeezing roller 7 thereby rotates, and the rotation direction of the squeezing roller 7 is opposite to the stirring direction of the squeezing roller 7 at its lower end, thereby ensuring that the material is sent between the squeezing roller 7 and the grinding plate 4 for grinding.

[0035] As the preferred technical solution of this embodiment, a support 13 is fixedly provided on the outer wall of the stop sleeve 10, and a transmission shaft 14 is rotatably connected to the support 13. One end of the transmission shaft 14 is connected to the rotating shaft of the extrusion roller 7 through a bevel gear transmission, and the other end is coaxially fixedly connected to the gear 11. Specifically, the axial direction of the transmission shaft 14 is parallel to the axial direction of the middle axis 1, and the bevel gear transmission between the upper end of the transmission shaft 14 and the rotating shaft of the extrusion roller 7 ensures that the rotation direction of the extrusion roller 7 at its lowermost tangential direction is opposite to the stirring direction of the extrusion roller 7 rotating with the middle axis 1; when the middle axis 1 rotates, the stop sleeve 10 drives the gear 11 to transmit with the inner gear ring 12, thereby causing the gear 11 to rotate, so as to drive the rotating shaft of the extrusion roller 7 to rotate through the transmission shaft 14 via the bevel gear transmission, and the extrusion roller 7 rotates smoothly.

[0036] When the raw materials are crushed and squeezed through the extrusion hole 5, the raw materials need to be discharged continuously. When the extrusion hole 5 is suspended, part of the material is retained in the extrusion hole 5, which may cause blockage due to hardening or adhesion after a period of suspension.

[0037] In another embodiment of the present invention, the set 6 is axially movable and arranged on the central axis 1. The central axis 1 can be switched to perform forward and reverse bidirectional rotation. The central axis 1 is connected to the set 6 through a two-way transmission component. The two-way transmission component is used to drive the set 6 to rotate synchronously when the central axis 1 rotates forward, and when the central axis 1 rotates reversely, the linkage set 6 moves axially back and forth, thereby driving the squeezing roller 7 to reciprocate and knock the grinding plate 4. Specifically, the axial movement of the set 6 on the central axis 1 drives the squeezing rollers 7 and the stopper sleeve 10 to move up and down as a whole; the two-way transmission component The arrangement of the parts enables the bidirectional rotation of the central axis 1 to drive the set 6 through two transmission modes respectively, specifically: when the central axis 1 rotates forward, it drives the set 6 to rotate synchronously, that is, each extrusion roller 7 can rotate with the set 6 and rotate in linkage to stir and crush the materials; when the central axis 1 rotates reversely, the rotation of the set 6 in this direction is limited, and the set 6 is linked to move axially back and forth, that is, it drives the extrusion roller 7 to rise and fall back and forth, so that the extrusion roller 7 repeatedly hits the grinding plate 4, and the grinding plate 4 vibrates, which can shake off the material retained in the extrusion hole 5 to a certain extent.

[0038] As a preferred technical solution of this embodiment, the dual-path transmission assembly includes a cavity 15 arranged in the kit 6, a convex ring 16 arranged in the cavity 15 is coaxially fixedly connected to the middle shaft 1, a one-way gear ring 17 meshing with each other is arranged between the top surface in the cavity 15 and the upper end of the convex ring 16, and a top ring 19 abutting against the lower end of the convex ring 16 is connected to the bottom surface of the cavity 15 through an elastic member 18. Specifically, the cavity 15 is cylindrical and sleeved on the middle shaft 1; the convex ring 16 can move axially relative to the cavity 15; each single tooth of the one-way gear ring 17 has one side arranged as a bearing surface parallel to the axial direction of the middle shaft 1, and the other side arranged as a slope surface; the tooth surface direction of the one-way gear ring 17 is specifically arranged as follows: when the middle shaft 1 rotates forward, it drives the convex ring 16 and the one-way gear ring 17 thereon to push the one-way gear ring 17 on the top surface of the cavity 15 with the bearing surface, and at this time, the kit 6 in this direction can rotate freely, thereby driving the kit 6 to rotate synchronously; and on the middle shaft 1 When reversing, it drives the convex ring 16 and the one-way toothed ring 17 on it to push the one-way toothed ring 17 on the top surface of the cavity 15 with the slope surface. At this time, the rotation of the set 6 in this direction is restricted, and the two one-way toothed rings 17 are squeezed to make the convex ring 16 move relatively in the cavity 15, that is, the set 6 rises axially on the central axis 1, and the convex ring 16 approaches the inner bottom surface of the cavity 15, then the elastic member 18 compresses and stores elastic potential energy. When the two one-way toothed rings 17 miss a single tooth each time, the elastic member 18 releases the elastic potential energy to move the position of the convex ring 16 in the cavity 15 back, that is, the set 6 descends axially on the central axis 1, and so on, so that the set 6 drives each squeezing roller 7 to rise and fall reciprocally to repeatedly knock the grinding plate 4; the elastic member 18 is preferably a spring, and the top ring 19 is used to resist the convex ring 16, and the contact surfaces of the two are smooth or lubricated to reduce the influence of the relative rotation of the convex ring 16 in the cavity 15.

[0039] As the preferred technical solution of this embodiment, a sleeve 20 is provided at the position where the shaft of the squeezing roller 7 passes through the stop sleeve 10, and a one-way bearing 21 is connected between the sleeve 20 and the shaft of the squeezing roller 7 to limit the one-way rotation of the squeezing roller 7. Specifically, when the middle axis 1 rotates forward, the rotation direction of the shaft of the squeezing roller 7 driven by the linkage assembly can rotate relative to the sleeve 20 through the one-way bearing 21, and when the middle axis 1 is reversed, the rotation direction of the shaft of the squeezing roller 7 that has a tendency to rotate is restricted by the one-way bearing 21, thereby also restricting the rotation of the set 6 relative to the middle axis 1, promoting the reciprocating lifting and lowering of the set 6.

[0040] In another embodiment of the present invention, an elastic ring 22 is provided on the bottom surface of the mixing chamber 2, and the grinding plate 4 is movably connected to the upper side of the elastic ring 22 and forms an elastic gap with the bottom surface of the mixing chamber 2. An extrusion tube 23 is provided at the lower end of the extrusion hole 5, and a through hole 24 matching the extrusion tube 23 is provided on the bottom surface of the mixing chamber 2. Specifically, the elastic ring 22 is arranged near the edge of the bottom surface of the mixing chamber 2; the setting of the elastic gap allows the grinding plate 4 to be lifted and lowered relative to the bottom surface of the mixing chamber 2; the lower end of the extrusion tube 23 can be elastically opened and closed, and a protrusion 25 is provided on the outer wall of the lower end of the extrusion tube 23, and a conical inner wall is provided at the lower end of the through hole 24 and is arranged against the protrusion 25; a deformation groove is provided at the lower end of the extrusion tube 23, and the lower end of the extrusion tube 23 is slightly opened outward when not subject to external force, so that the aperture of the lower end of the extrusion tube 23 is larger than the aperture of the upper end of the extrusion tube 23; With the elastic support of the elastic ring 22, when the elastic gap is the largest, the height of the grinding plate 4 drives the raised portion 25 at the lower end of the extrusion tube 23 to abut against the upper side of the tapered inner wall at the lower end of the through hole 24. At this time, the upper and lower end apertures of the extrusion tube 23 are uniform, and after the grinding plate 4 is struck by the extrusion roller 7, the grinding plate 4 moves downward, driving the extrusion tube 23 to move downward, and the extrusion tube 23 drives the raised portion 25 to move downward to approach the lower side of the tapered inner wall at the lower end of the through hole 24 or to leave. As a result, the lower end of the extrusion tube 23 is elastically slightly expanded to expand the aperture, making it more convenient for the material retained in the extrusion tube 23 to be discharged downward after being struck; after the grinding plate 4 is affected by the striking, it is elastically supported by the elastic ring 22 to reset, that is, the lower end of the extrusion tube 23 rises back to the position corresponding to the tapered inner wall at the lower end of the through hole 24, and the upper and lower end apertures of the extrusion tube 23 are restored to be consistent.

[0041] An organic fertilizer production line includes the above-mentioned granulation equipment, and also includes: a feeding pipe 26 and a discharging belt 27. The feeding pipe 26 feeds the production raw materials into the mixing bin 2, and the discharging belt 27 receives the products discharged from the collecting bin 3 and transports them. Specifically, the end of the feeding pipe 26 is bent downward to correspond to the feed hopper at the upper end of the mixing bin 2, and the discharging belt 27 is connected to the lower side of the side discharge port of the collecting bin 3.
