[0037] A granulating method of a feed mixing and granulating device, comprising the following steps:

[0038] (1) The raw materials for preparing the feed are poured into the hopper 201, and are preliminarily extruded and broken by the pressing roller 202.

[0039] (2) The broken raw materials enter the discharge cylinder 302, and are extruded and formed by the forming roller one 306 and the forming roller two 307 inside the discharge cylinder 302.

[0040] (3) The formed feed particles are collected by the upper collecting box 401 and the lower collecting box 402.

[0041] Working principle: in the preparation of feed particles, first of all for the preparation of feed raw materials are poured into the hopper 201. At the same time start two-way motor 203, at this time two-way motor 203 on both sides of the output shaft drive two first gear 204 rotation, so that the first gear 204 meshing with the second gear 204 will rotate, through two second gear 205 through the pulley and belt assembly 1 206 in the belt connection, so the belt assembly 1 206 will also rotate, then the third gear 207 with the second gear 205 meshing will drive a pressure roller 202 rotation, belt assembly 1 206 through the pulley connected pressure roller 202 will also rotate, so that two pressure roller 202 rotating towards each other, can be a preliminary extrusion broken raw materials, at the same time, when encountered difficult to break the material between the two pressure roller 202, pressure roller 202 will be subjected to a thrust, at this time with the adjusting rod 209 connected pulley pressure roller 202 will drive the adjusting rod 209 on the hopper 201 sliding, this time will pull the return spring 1 210, the return spring 1 210 is to assist the adjusting rod 209 and pressure roller 202 reset. Of course, set to pressure roller 202 and adjusting rod 209 sliding, is also a kind of protection of two-way motor 203, to prevent damage due to overload two-way motor 203, while the adjusting shaft 208 is also to prevent damage to two-way motor 203, the role of the return spring 214 is to assist the adjusting shaft 208 connected pulley reset. And the surface of the pressure roller 202 is provided with pattern, the purpose of this is to increase the friction of the raw materials, improve the crushing effect.

[0042] After the raw materials through the pressure roller 202 fall, will fall into the crushing box 211, at this time the rotating shaft 7 will drive the two layers of crushing blade 212 on the center shaft 7 rotation, on the one hand, the crushing blade 212 can be through the pressure roller 202 of raw materials are no longer into a group of stirring, on the other hand, the crushing blade 212 can be broken again raw materials stirring, at this time the raw materials will be through the crushing blade 212 on the bottom surface and side of the discharge hole 213 fall into the forming barrel 301 below the crushing box 211.

[0043] After the raw materials enter into the forming barrel 301, the raw materials will continue to fall into the discharging barrel 302 under the action of gravity, at this time, the triangular disc 305 and the rotating disc 308 fixedly installed on the central shaft 7 will rotate, so that the forming roller one 306 on the triangular disc 305 and the forming roller two 307 on the rotating disc 308 rotate, so that the forming roller one 306 and the forming roller two 307 extrude the raw materials, and the feed particles after extrusion will enter into the upper collecting box 401 and the lower collecting box 402 through the discharge hole one 303 and the discharge hole two 304 respectively, and then fall into the pocket through the opening two 404 and the opening one 403 respectively, the diameters of the discharge hole one 303 and the discharge hole two 304 are different, so that the feed with different diameters can be prepared, and the screening of the feed particles with different diameters is reduced. Of course, in the process of rotation of the central shaft 7, the scraper 309 located inside the forming barrel 301 on the central shaft 7 can clean the inner wall of the forming barrel 301, so as to prevent the raw materials from adhering to the surface of the forming barrel 301. It should be noted that the rotation of the central shaft 7 relies on the transmission of the bevel gear set 6 and the power of the bevel gear set 6, which is derived from the driving motor 5.

[0044] In addition, in the process of rotation of the central shaft 7, the central shaft 7 can drive the rubber wheel 410 to rotate through friction, the rotating rubber wheel 410 drives the rotating shaft 408 to rotate through the belt assembly two 409, so that the belt 407 rotates, and the belt 407 can drive the rotating table 406 to rotate, so that the pushing plate 405 fixedly connected to the rotating table 406 rotates, the pushing plate 405 pushes the raw materials falling into the upper collecting box 401 to the opening two 404, so as to improve the collecting speed. At the same time, when the rotating table 406 rotates, the mounting plate 411 fixedly installed on the rotating table 406 also rotates, so that the trapezoidal plate 413 rotates relative to the discharging barrel 302, and the purpose of this is to scrape the residues in the discharge hole one 303 of the discharging barrel 302 clean through the surface of the trapezoidal plate 413 in contact with the discharging barrel 302. Of course, the distance between the trapezoidal plate 413 and the discharging barrel 302 can be adjusted, and the specific adjustment method is to rotate the lead screw 412 to move the trapezoidal plate 413 on the optical axis 414.
