DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] The utility model provides two technical schemes:

[0027] Figures 1-5 The first embodiment is shown: a kind of organic fertilizer processing granulator, including rack 1, and the top of rack 1 is equipped with granulating mechanism, and granulating mechanism includes:

[0028] Machine body assembly 2 is arranged at the top of rack 1;

[0029] The roller assembly 3 is arranged in the machine body assembly 2, and the roller assembly 3 comprises a center block 31, the outer surfaces of both sides of the center block 31 are fixedly connected with fixed rods 33, the outer walls of the fixed rods 33 are fixedly sleeved with bearing rings 34, the outer walls of the bearing rings 34 are fixedly sleeved with hollow compression rollers 35, the hollow compression rollers 35 are coaxially arranged with the fixed rods 33, and a plurality of straight slots 36 are formed through the outer walls of the hollow compression rollers 35.

[0030] The end portions of the fixed rods 33 are fixedly connected with connecting plates 37, the connecting plates 37 are arranged in the hollow compression rollers 35, the outer surface of one side of each connecting plate 37 is fixedly connected with an eccentric rod 38, the axis line of the eccentric rod 38 is arranged above the axis line of the fixed rod 33, and a T-shaped ring groove 39 is formed in the outer wall of the eccentric rod 38. The outer surface of one side of each stretchable block 310 is fixedly connected with a connecting rod 311, the outer wall of the connecting rod 311 is fixedly connected with a connecting shaft 312 at a position close to the distal end, the end portion of the connecting shaft 312 is rotatably provided with a roller 313, and the roller 313 is rotatably connected with the inner portion of the T-shaped ring groove 39.

[0031] Specifically, when the hollow compression roller 35 rolls, the stretchable blocks 310 make circular motion in the T-shaped ring groove 39 of the eccentric rod 38 through the cooperation of the connecting rod 311 and the roller 313, thereby driving the stretchable blocks 310 to rotate around the eccentric rod 38. Since the axis line of the eccentric rod 38 is arranged above the axis line of the fixed rod 33, the lower half of the stretchable blocks 310 is retracted, so that the straight slots 36 on one side of the contact surface between the hollow compression roller 35 and the material are exposed, the friction with the material is increased, and the material is prevented from slipping. The upper half of the stretchable blocks 310 is extended, so that the material filled in the straight slots 36 can be extruded, the straight slots 36 are kept unobstructed, the friction between the hollow compression roller 35 and the material is continuously maintained, the material is stably extruded, and the granulation efficiency is improved.

[0032] Further, the friction of the connecting rod 311 during movement can be reduced through the arrangement of the roller 313, so that the smoothness of the extension and retraction of the stretchable blocks 310 is improved.

[0033] Figures 1-5 The second embodiment is shown, and the main difference from the first embodiment is that the machine body assembly 2 comprises a machine cylinder 21, the inner wall of the machine cylinder 21 is provided with a flat die disc 22, the top surface of the flat die disc 22 is in contact with the outer wall of the hollow compression roller 35, the inner portion of the machine cylinder 21 is provided with a driving shaft 23, the driving shaft 23 is movably penetrated through the flat die disc 22, the outer wall of the driving shaft 23 is fixedly sleeved with a support plate 24 at a position above the flat die disc 22, and the top end of the support plate 24 is fixedly connected with two positioning pins 25.

[0034] Specifically, the center block 31 is driven to rotate synchronously by rotating the external motor drive shaft 23. When the center block 31 rotates, the hollow compression roller 35 rolls on the flat die disc 22 to extrude and granulate the material.

[0035] In the embodiment, the center block 31 is movably sleeved on the drive shaft 23, the bottom surface of the center block 31 is provided with a positioning hole 32 matched with the positioning pin 25, and the outer wall of the drive shaft 23 is threadedly connected with a nut 4 at a position close to the top end, and the bottom surface of the nut 4 is in close contact with the top surface of the center block 31.

[0036] Specifically, the positioning hole 32 in the bottom surface of the center block 31 is matched with the positioning pin 25 of the support plate 24, so that the center block 31 and the drive shaft 23 are positioned in the circumferential direction, ensuring that the drive shaft 23 can drive the center block 31 to rotate synchronously, and at the same time, the nut 4 limits the center block 31 to prevent the center block 31 from moving axially on the drive shaft 23, ensuring the stability of the entire granulator structure and the reliability of the transmission, and the nut 4 is removed to facilitate the removal of the entire roller compression assembly 3, facilitating the later maintenance.

[0037] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0038] Working principle: during granulation, the drive shaft 23 rotates to drive the center block 31 to rotate synchronously. When the center block 31 rotates, the hollow compression roller 35 rolls on the flat die disc 22 to extrude and granulate the material.

[0039] During the granulation process, the hollow compression roller 35 continuously rolls, but the fixed rod 33 and the eccentric rod 38 remain stationary and do not rotate. When the hollow compression roller 35 rolls, it drives the expansion block 310 to rotate, and the expansion block 310 is constrained by the connecting rod 311, the connecting shaft 312 and the roller 313, so that the expansion block 310 makes a circular motion around the fixed eccentric rod 38, and the axis of the eccentric rod 38 is arranged above the axis of the fixed rod 33. When the expansion block 310 makes a circular motion, the upper half of the expansion block 310 is pushed out, and the lower half of the expansion block 310 is pulled in. When the lower half of the expansion block 310 is pulled in, the straight slot 36 on the side of the hollow compression roller 35 in contact with the material is exposed, increasing the friction with the material and preventing the material from slipping. When the upper half of the expansion block 310 is pushed out, the material filled in the straight slot 36 is extruded, keeping the straight slot 36 unobstructed, thereby continuously maintaining the friction between the compression roller and the material, ensuring that the material is stably extruded and improving the granulation efficiency.
