Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Reference Figure 1-5 , a seed pelletizing device, comprising a stirring device 1, the stirring device 1 comprising a shell 2 and a stirring assembly 3, and a screening device 4 is provided at the output end of the stirring device 1; The screening device 4 comprises a support 41, on which a screen 42 is arranged, and on which a collecting frame 43 matching with the screen 42 is also arranged; The stirring assembly 3 includes a base 31 on which a stirring drum 32 is rotatably arranged. A driving device 33 for driving the stirring drum 32 to rotate is arranged between the base 31 and the stirring drum 32 . An angle adjustment mechanism 5 is arranged between the base 31 and the housing 2 . A feeding port 21 is arranged on the housing 2 .
[0020] In the present invention, the driving device 33 drives the mixing drum 32 to rotate, the seeds in the mixing drum 32 are mixed with the adhesive, and then the powder is added through the feeding port 21 to mix the seeds and the powder evenly. The angle of the base 31 and the mixing drum 32 is adjusted by the angle adjustment mechanism 5. During mixing, the mixing drum 32 can be rotated to mix the seeds inside evenly, and the force generated by the shaking of the seed mixing can be used to separate the seeds adhered to the mixing drum 32, so that the seeds can be fully mixed with the powder to form a complete coating. In some embodiments, a switch door is provided on the mixing drum 32 to prevent the seeds and powder from being scattered and wasted when the mixing drum 32 is rotated.
[0021] Furthermore, in this embodiment, a movable frame 44 is slidably provided on the bracket 41, and the screen 42 is fixedly provided on the movable frame 44. The movable frame 44 and the collecting frame 43 are both provided with discharge ports. By driving the movable frame 44 to move, the screen 42 and the seeds are driven to move, so that the seeds are screened and the excess powder is screened out. The screen 42 is an inclined structure to facilitate the movement of the seeds.
[0022] In this embodiment, the driving device 33 includes a first motor 331, the output shaft of the first motor 331 is fixedly provided with a gear 332, and the outer wall of the mixing drum 32 is fixedly provided with a gear ring 333 meshing with the gear 332. The first motor 331 drives the gear 332 to drive the gear ring 333 and the mixing drum 32 to rotate, so as to mix the seeds inside with the adhesive or powder.
[0023] Furthermore, in this embodiment, a second motor 45 is fixedly provided on the bracket 41, and the output shaft of the second motor 45 is connected to the movable frame 44 through a linkage structure 46. The second motor and the linkage structure 46 cooperate to control the reciprocating movement of the movable frame 44 to push the seeds forward and separate the seeds from excess powder. In some embodiments, a vibrator is provided on the movable frame 44 or the screen 42.
[0024] In this embodiment, the linkage structure 46 includes a cam 461 and a connecting rod 462. The connecting rod 462 is connected to the movable frame 44. The cam 461 is fixedly arranged on the output shaft of the second motor 45 and is dynamically connected to the connecting rod 462. The connecting rod 462 is eccentrically connected to the cam 461. When the second motor 45 drives the cam 461 to rotate, it will reciprocate and push the connecting rod 462 and the movable frame 44 to move, thereby screening the seeds.
[0025] It should be noted that, in this embodiment, the connecting rod 462 is rotatably connected to the cam 461, and a connecting seat 463 rotatably connected to the connecting rod 462 is fixedly provided on the movable frame 44. The connecting rod 462 includes a double-headed screw and two sleeves threadedly connected to the two ends of the double-headed screw respectively, and the two sleeves are rotatably connected to the cam 461 and the connecting seat 463 respectively.
[0026] In addition, in this embodiment, a guide rail 47 is fixedly provided on the bracket 41, and a guide wheel 48 is rotatably provided at the lower end of the movable frame 44. A groove corresponding to the guide rail 47 is provided on the guide wheel 48. The guide wheel 48 cooperates with the guide rail 47 to limit the moving trajectory of the movable frame 44, thereby preventing the movable frame 44 from deviating from the preset trajectory and causing damage to the connecting rod 462.
[0027] In detail, in this embodiment, the angle adjustment mechanism 5 includes a first rotating shaft 51 and a height adjustment structure 52. The first rotating shaft 51 is fixedly connected to the outer shell 2, and the base 31 is rotatably connected to the first rotating shaft 51. The base 31 and the mixing drum 32 can rotate around the first rotating shaft 51 to adjust the angle, and the height adjustment structure 52 provides the base 31 with rotational power.
[0028] In this embodiment, the height adjustment structure 52 includes a scissor-type lifting mechanism 521 and a base 522. The scissor-type lifting mechanism 521 is arranged on the base 522. The output end of the scissor-type lifting mechanism 521 is fixedly connected to the base 31. The scissor-type lifting mechanism 521 drives the base 522 and the base 31 to move up and down, so that the base 31 and the mixing drum 32 rotate around the first rotating shaft 51 as the center to adjust the angle.
[0029] In more detail, in this embodiment, a second rotating shaft 523 is rotatably provided on the base 522, and the second rotating shaft 523 is rotatably connected to the outer shell 2. When the angle of the base 31 and the mixing drum 32 changes, the base 522 will change the angle of the scissor-type lifting mechanism 521 by rotating with the second rotating shaft 523 as the center, thereby preventing the scissor-type lifting mechanism 521 from being damaged or broken.
[0030] Working mode: When working, the first motor 331 drives the gear 332 to drive the gear ring 333 and the mixing drum 32 to rotate, and the seeds inside are mixed with the adhesive or powder. The scissor-type lifting mechanism 521 drives the base 522 and the base 31 to move up and down, so that the base 31 and the mixing drum 32 rotate and adjust the angle with the first rotating shaft 51 as the center. When stirring, the seeds are shaken and mixed, and the force generated by the seed mixing and shaking is used to separate the seeds adhered to the mixing drum 32, so that the seeds can be fully mixed with the powder to form a complete coating. The angle of the mixing drum 32 can also be adjusted to facilitate the transportation of the mixed seeds to the screening device 4, and the cam 461 is driven to rotate by the second motor 45, thereby reciprocatingly pushing the connecting rod 462 and the moving frame 44 to move, and the seeds are screened to separate the seeds from the excess powder.
