Further, the connecting line of the scraping teeth passes through the center of the circle of the stator, and the stator is manufactured by casting.
Further, the scraping teeth are positioned at the positions of a plurality of grinding teeth, are arranged in a crossing manner, and the stator is formed by casting or milling.
Further, 3-4 rows of teeth scraping and the like are arranged.
Further, the center of the stator is sequentially provided with a feed hopper, a blanking port and a bulk hopper from top to bottom, and the edges of the bulk hopper gradually reduce in height.
Further, a spiral presser is arranged in the bulk hopper at the center of the rotor.
The utility model has the advantages compared with the prior art that:
The utility model improves the structures of the grinding groove and the grinding teeth, so that the grinding groove and the grinding teeth have shearing angles when in a ring shape to grind, but the grinding groove with the structure can scrape internal powder through the continuously rotating scraping teeth, thereby avoiding the difficulty in discharging the powder after being continuously compressed in the grinding groove, influencing subsequent products and reducing grinding capability due to internal deterioration.

Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
As shown in fig. 1-6:
The utility model provides a powder fodder grinding equipment, grinding equipment includes rotor 2 and stator 1 of concentric installation, and stator 1 is located the upside, and rotor 2 is located the downside, rotor 2 upper surface sets up a plurality of annular grinding grooves 21 with one heart, sets up a plurality of grinding teeth 15 at stator 1 lower surface, and grinding teeth 15 all are certain contained angle setting with the line at its root and stator 1 centre of a circle, and still is provided with the scraping teeth 14 of a plurality of rows one-to-one annular grinding grooves 21 at stator 1 lower surface, scrapes teeth 14 and all be with the fan-shaped structure of corresponding grinding groove 21 inside and outside diameter.
The utility model improves the existing radial grinding grooves 21 and grinding teeth 15, firstly, the grinding grooves 21 adopt concentric annular structures, and in order to match the design of the grinding grooves 21, the connecting lines of the grinding teeth 15 and the root parts of the grinding teeth and the circle center of the stator 1 are all arranged at a certain included angle (the included angle alpha is only required to be 50-60 degrees), so that shearing angles can be still generated between the grinding teeth 15 and the grinding grooves 21 when the grinding teeth 15 rotate, the grinding capability is ensured, when the rotor 2 rotates, the scraping teeth 14 rotate relative to the grinding grooves 21, the internal feed powder is continuously scraped out for grinding, then the first stage and the first stage move outwards, finally the grinding formation is carried out, and the scraping teeth 14 are all fan-shaped structures corresponding to the inner diameter and the outer diameter of the grinding grooves 21, so that the scraping teeth 14 can always be attached to the grinding grooves 21 when rotating.
The scraping teeth 14 are arranged in a plurality of modes, but in consideration of convenient processing, one is that the connecting line of the scraping teeth 14 passes through the center of the stator 1, and as the grinding teeth 15 are arranged at a certain included angle with the connecting line of the root part of the grinding teeth and the center of the stator 1, part of the scraping teeth 14 are interfered with the grinding teeth 15, and the stator 1 with the structure is most convenient to manufacture by casting.
