In the normal working process, the upper cover 32 is attached to the top wall of the box body 1, at the moment, the switch 31 is extruded by the upper cover 32, and the electromagnetic valve 30 is in an open state; in the working process, the feed in the box body 1 is gradually ground, so that workers need to add the feed into the box body, and in order to prevent the gas circularly flowing in the box body 1 from leaking to the outside and polluting the outside, the gas circulation needs to be stopped when the feed is added; when the feed is added to the worker, the worker rotates the upper cover 32, the upper cover 32 is separated from the switch 31, the electromagnetic valve 30 is powered off, the circulating pipe 12 and the box body 1 are in a separation state, and therefore when the feed is added to the worker, the air flow in the box body 1 stops circulating, so that the gas containing the feed powder can be prevented from leaking to the outside, and the effect of preventing the damage to the body of the worker due to the fact that the feed powder is sucked is achieved.

The working principle is as follows: when needs grind the fodder, at first start first motor 4 and second motor 7, then pour the fodder into box 1, part fodder will drop the grinding district that forms between first grinding roller 3 and the second grinding roller 5 this moment, meanwhile first motor 4 drives first grinding roller 3 through dwang 2 and rotates, because second grinding roller 5 is in quiescent condition, consequently at first grinding roller 3 rotation in-process, produce relative displacement between first grinding roller 3 and the second grinding roller 5, at this in-process, the fodder that is arranged in grinding the district is ground into the likepowder gradually, thereby the grinding of fodder has been realized.

In the rotating process of the rotating rod 2, the rotating rod 2 drives the extrusion plate 15 to rotate together, and in the process, the feed stacked above the first grinding roller 3 and the second grinding roller 5 is stirred by the extrusion plate 15, so that the feed can be prevented from being stacked together; when the stripper plate 15 promoted elasticity piece 14, elasticity piece 14 crooked and take place deformation, because elasticity piece 14 fixed mounting is on the roof of second grinding roller 5, consequently when stripper plate 15 breaks away from the contact with elasticity piece 14, elasticity piece 14 recovers and shakes back and forth, thereby the range of rocking of fodder has been increased, at stripper plate 15 rotation in-process, the fodder that contacts with stripper plate 15 lateral wall receives the thrust on inclined plane, under the effect of thrust along vertical decurrent component force, the fodder will be pushed and get into the grinding zone.

Along with operating time's increase, the fodder in the grinding district is ground into the slice gradually, under the effect of gravity, the slice fodder drops downwards gradually and finally drops the lowest end in grinding district, the bottom of slice fodder contacts with the roof of abrasive disk 8 this moment, because second motor 7 drives abrasive disk 8 high-speed rotation, and when the slice fodder drops on the roof of abrasive disk 8, can be fixed the slice under limiting plate 9's effect, thereby prevent that abrasive disk 8 from driving slice fodder and moving together, consequently under limiting plate 9's effect, when abrasive disk 8 rotates, can produce relative displacement between slice fodder and the abrasive disk 8, consequently when the fodder drops on the roof of abrasive disk 8, under the effect of frictional force, the great slice of surface area will be ground into the powder gradually.

And the lamellar fodder on 8 roofs of abrasive disc that drop can be along with abrasive disc 8 fast turn together before contacting with limiting plate 9, in the twinkling of an eye in fodder and 9 contacts of limiting plate, bump between fodder and the limiting plate 9, the impact force that limiting plate 9 received at this moment transmits for second grinding roller 5, thereby can make the powdered fodder vibrations of attaching to on 5 inner walls of second grinding roller, and shake powdered fodder from the inner wall of second grinding roller 5 and fall, thereby ensure that the second grinding roller 5 surface has great frictional force.

Meanwhile, the second motor 7 drives the fan blades 11 to rotate, in the process of rotating the fan blades 11, the fan blades 11 discharge the air in the limiting sleeve 6 into the box body 1, in the process, the powder on the upper surface of the grinding disc 8 is separated from the disc grinding disc under the action of centrifugal force and flows into the collecting box 10 along with the air flow, after the powdered feed enters the collecting box 10, the feed is gathered in the collecting box 10 under the action of the filter screen 13, then the air flow enters the circulating pipe 12 and enters the top of the box body 1 along the circulating pipe 12, at the moment, the air on the top of the box body 1 flows downwards, so that the air flow in the box body 1 and the collecting box 10 is in a circulating flow state, the impact force on the powder on the side wall of the first grinding roller 3, the inner wall of the second grinding roller 5 and the top wall of the grinding disc 8 is increased, and the surfaces of the first grinding roller 3, the second grinding roller 5 and the grinding disc 8 are ensured to be in a rough state.

In the initial state, the first pneumatic telescopic rod 18 is in a state of incomplete contraction, the impact rod 17 is in close contact with the side wall of the first cavity 33, and the second cavity 34 is in a negative pressure state; when the elastic block 14 is extruded, the air in the second cavity 34 enters the first pneumatic telescopic rod 18 along the first air pipe 19, at this time, the output end of the first pneumatic telescopic rod 18 extends and drives the mounting rod 16 to move along the chute, and in the process that the mounting rod 16 moves along the chute, the impact rod 17 is separated from contact with the side wall of the first cavity 33; at the moment when the squeezing plate 15 is separated from contact with the elastic block 14, the elastic block 14 is rapidly restored, and at this moment, the second cavity 34 is restored, so that the gas in the first pneumatic telescopic rod 18 flows back into the second cavity 34 along the first gas pipe 19, so that the second telescopic rod is contracted and drives the mounting rod 16 to move together, at this moment, the mounting rod 16 drives the impact rod 17 to impact the side wall of the second cavity 34, so that the side wall of the second cavity 34 is subjected to horizontal impact force, the impact force is transmitted to the powder attached to the surface of the second grinding roller 5, and the powder attached to the surface of the second grinding roller 5 falls off from the surface of the second grinding roller 5 under the action of the horizontal impact force; as the working time is accumulated, the surface of the striking rod 17 is gradually deformed by impact, so that the worker can quickly remove the broken striking rod 17 from the mounting rod 16 by screwing the screw 20 and replace the striking rod 17 by the communicating tube 21.

In the initial state, the second pneumatic telescopic rod 25 is in a contraction state; during operation, the pressing plate 15 intermittently presses the elastic block 14, when the elastic block 14 is pressed, part of the air in the second cavity 34 flows into the fifth cavity 37 along the fourth air pipe 29, at this time, the air in the fifth cavity 37 passes through the fourth cavity 36 and the third air pipe 28 and then enters the second pneumatic telescopic rod 25, at this time, the second pneumatic telescopic rod 25 stretches and drives the first magnet 26 to move downwards, during the downward movement of the first magnet 26, under the attraction force of the first magnet 26 and the second magnet 27, the second magnet 27 drives the scraper 24 to move downwards along with the first magnet 26, during the downward movement of the scraper 24, the powder attached to the surface of the first grinding roller 3 is cleaned by the scraper 24, so that the surface of the first grinding roller 3 can be ensured to be kept in a rough state, during normal operation, the upper cover 32 is attached to the top wall of the box body 1, at this time, the switch 31 is pressed by the upper cover 32, and the electromagnetic valve 30 is in an open state; in the working process, the feed in the box body 1 is gradually ground, so that workers need to add the feed into the box body, and in order to prevent the gas circularly flowing in the box body 1 from leaking to the outside and polluting the outside, the gas circulation needs to be stopped when the feed is added; when the worker adds the feed, the worker rotates the upper cover 32, the upper cover 32 is separated from the switch 31, the electromagnetic valve 30 is powered off, the circulating pipe 12 is separated from the box body 1, and therefore when the worker adds the feed, the air flow in the box body 1 stops circulating, and therefore the air containing the feed powder can be prevented from leaking to the outside.

The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
