A feed pellet forming apparatus as claimed in claim 1, wherein: the inside of squeeze roll (14) is equipped with a plurality of annular striking cavities (23), and the middle part that strikes cavity (23) is equipped with dead lever (24), and annular distribution has many tip and striking cavity (23) lateral wall fixed connection's impact bar (25) on dead lever (24), and sliding sleeve is equipped with striking block (26) on impact bar (25).
5. A feed pellet forming apparatus as claimed in claim 1, wherein: the frame body (1) is provided with an installation plate (27); the scraper device (16) comprises a motor (28) positioned on the mounting plate (27), the output end of the motor (28) is connected with a plurality of rotary blades (29), and the rotary blades (29) are positioned below the extrusion holes (15).
6. A feed pellet forming apparatus as claimed in claim 5, characterized in that: and a collecting frame (30) positioned below the rotary blade (29) is arranged on the mounting plate (27).
7. A feed pellet forming apparatus as claimed in claim 1, wherein: the feeding cavity (4) is trumpet-shaped.
8. A pellet forming method of a pellet forming apparatus as claimed in any one of claims 1 to 7, wherein: the raw materials fall into the upper surface of the grinding block through the feeding cavity for standby, and the raw materials on the upper surface of the grinding block are stirred to fall into the feeding hole and reach between the lower surface of the grinding block and the upper surface of the material crushing hammer; in the process that a telescopic oil cylinder drives a grinding block to move up and down through a piston rod, the grinding block is in threaded fit with a crushing cavity to rotate, raw materials between the lower surface of the grinding block and the upper surface of a crushing hammer are ground in the rotating process of the grinding block, the ground raw materials fall onto a stress plate through a gap between the crushing hammer and the side wall of the crushing cavity, and the crushed hammer is driven by the telescopic oil cylinder to beat and crush the ground raw materials on the stress plate and then enter an extrusion cavity through filter holes in the stress plate; in the extrusion intracavity, because the threaded rod can drive rather than screw-thread fit's rotation cover positive and negative rotation along with crushed aggregates hammer up-and-down motion, rotate the cover and drive the extrusion roller through the pivot and rotate positive and negative again to through extrusion hole extrusion to the kibbling raw and other materials that fall into the extrusion intracavity, cut by the scraper device of support body below again and form the fodder granule.
9. A method of forming a feed pellet as claimed in claim 8 wherein: because the threaded rod drives the swivel becket rotation along with crushed aggregates hammer up-and-down motion, the swivel becket drives the gyro wheel through the pivot and rolls on the rolling track, provides pivoted stability on the one hand, and the epaxial round brush of on the other hand brushes the atress board lower surface, prevents that kibbling raw and other materials from taking place to block up in the filtration pore of atress board for kibbling raw and other materials fall into the extrusion intracavity as far as.
10. A method of forming a feed pellet as claimed in claim 8 wherein: when the impact rod of the impact cavity inside the extrusion roller rotates upwards in the rolling process of the extrusion roller, the impact block at the end part of the impact rod rises along with the impact rod and slides downwards along the impact rod to the fixed rod at the rotating center, so that the rotating moment at the upper end of the impact rod is reduced; when the impact rod in the inside impact cavity of the squeeze roller rotates downwards, the impact block at the joint of the fixed rod and the impact rod slides downwards along with gravity to impact the side wall of the impact cavity, so that vibration is formed when impact is completed, the extrusion effect of the squeeze roller is increased, and vibration is provided to vibrate materials in the extrusion hole to perform blanking.
