the collecting box 10 with the input end communicated with the box 1 is fixedly inserted on the side wall of the box 1, the fan blade 11 which blows downwards is fixedly sleeved on the power output end of the second motor 7, the circulating pipe 12 with the top end extending to the inner top wall of the box 1 is fixedly inserted on the top wall of the collecting box 10, the filter screen 13 matched with the circulating pipe 12 is fixedly installed on the inner wall of the collecting box 10, and the vibrating mechanism matched with the fan blade 11 is arranged on the box 1.
Elastic blocks 14 are uniformly and fixedly arranged on the top wall of the second grinding roller 5; the rotating rod 2 is horizontally and fixedly provided with an extrusion plate 15 matched with the elastic block 14, and the side wall of the extrusion plate 15 is an inclined plane.
When the feed needs to be ground, the first motor 4 and the second motor 7 are started firstly, then the feed is poured into the box 1, at the moment, part of the feed falls into a grinding area formed between the first grinding roller 3 and the second grinding roller 5, meanwhile, the first motor 4 drives the first grinding roller 3 to rotate through the rotating rod 2, and as the second grinding roller 5 is in a static state, relative displacement is generated between the first grinding roller 3 and the second grinding roller 5 in the rotating process of the first grinding roller 3, and the feed in the grinding area is gradually ground into powder in the process, so that the feed is ground.
In the process of rotating the rotating rod 2, the rotating rod 2 drives the extruding plate 15 to rotate together, and in the process, the feed accumulated above the first grinding roller 3 and the second grinding roller 5 is stirred by the extruding plate 15, so that the feed can be prevented from accumulating together; when the extrusion plate 15 pushes the elastic block 14, the elastic block 14 is bent and deformed, and since the elastic block 14 is fixedly installed on the top wall of the second grinding roller 5, when the extrusion plate 15 is out of contact with the elastic block 14, the elastic block 14 is restored and shakes back and forth, thereby increasing the shaking amplitude of the feed, and playing a role in ensuring that the feed can normally fall into the grinding area.

In the normal working process, 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 a worker needs 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 to pollute the outside, the gas circulation needs to be stopped when the feed is added; when the staff adds the fodder, the staff rotates upper cover 32, and upper cover 32 breaks away from the contact with switch 31 this moment, therefore solenoid valve 30 outage, and circulating pipe 12 is in the separation state with box 1 this moment, therefore when the staff adds the fodder, the air current in box 1 stops circulating to can prevent that the gas that contains fodder powder from revealing to the external world, play the effect that prevents that the staff from causing harm to the health because of inhaling the powder.
Working principle: when the feed needs to be ground, the first motor 4 and the second motor 7 are started firstly, then the feed is poured into the box 1, at the moment, part of the feed falls into a grinding area formed between the first grinding roller 3 and the second grinding roller 5, meanwhile, the first motor 4 drives the first grinding roller 3 to rotate through the rotating rod 2, and as the second grinding roller 5 is in a static state, relative displacement is generated between the first grinding roller 3 and the second grinding roller 5 in the rotating process of the first grinding roller 3, and the feed in the grinding area is gradually ground into powder in the process, so that the feed is ground.
In the process of rotating the rotating rod 2, the rotating rod 2 drives the extruding plate 15 to rotate together, and in the process, the feed accumulated above the first grinding roller 3 and the second grinding roller 5 is stirred by the extruding plate 15, so that the feed can be prevented from accumulating together; when the extrusion plate 15 pushes the elastic block 14, the elastic block 14 is bent and deformed, and since the elastic block 14 is fixedly installed on the top wall of the second grinding roller 5, when the extrusion plate 15 is out of contact with the elastic block 14, the elastic block 14 is restored and shakes back and forth, thereby increasing the shaking amplitude of the feed, and in the rotation process of the extrusion plate 15, the feed contacting with the side wall of the extrusion plate 15 is pushed by the inclined surface, and under the action of the partial force of the pushing force along the vertical downward direction, the feed is extruded into the grinding area.
With the increase of the working time, the feed in the grinding zone is gradually ground into a flake, the flake feed gradually drops downwards under the action of gravity and finally drops to the lowest end of the grinding zone, at this time, the bottom of the flake feed is contacted with the top wall of the grinding disc 8, because the second motor 7 drives the grinding disc 8 to rotate at a high speed, and when the flake feed drops to the top wall of the grinding disc 8, the flake can be fixed under the action of the limiting plate 9, so that the grinding disc 8 is prevented from driving the flake feed to move together, and therefore, under the action of the limiting plate 9, when the grinding disc 8 rotates, relative displacement can be generated between the flake feed and the grinding disc 8, and therefore, when the feed drops to the top wall of the grinding disc 8, the flake with larger surface area is gradually ground into powder under the action of friction force.
And the lamellar feed on the top wall of the falling grinding disc 8 can rotate rapidly along with the grinding disc 8 before contacting with the limiting plate 9, and at the moment of contacting the feed with the limiting plate 9, the feed collides with the limiting plate 9, and the impact force received by the limiting plate 9 is transmitted to the second grinding roller 5, so that the powdery feed attached to the inner wall of the second grinding roller 5 can vibrate and the powdery feed is vibrated from the inner wall of the second grinding roller 5, and the larger friction force exists on the surface of the second grinding roller 5.
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 gas in the limit sleeve 6 into the box body 1, in the process, powder on the upper surface of the grinding disc 8 is separated from contact with the disc grinding disc under the action of centrifugal force and flows into the collecting box 10 along with the gas flow, after the powdery feed enters the collecting box 10, the feed is collected in the collecting box 10 under the action of the filter screen 13, then the gas flow enters the circulating pipe 12 and enters the top of the box body 1 along the circulating pipe 12, at the moment, the gas at the top of the box body 1 flows downwards, so that the gas flow in the box body 1 and the collecting box body 10 is in a circulating flow state, and the impact force exerted 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 an incompletely contracted state, the striking 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 gas in the second cavity 34 enters the first pneumatic telescopic rod 18 along the first gas pipe 19, at this time, the output end of the first pneumatic telescopic rod 18 stretches and drives the mounting rod 16 to move along the sliding groove, and in the process that the mounting rod 16 moves along the sliding groove, the impact rod 17 is out of contact with the side wall of the first cavity 33; when the extrusion plate 15 is separated from the elastic block 14, the elastic block 14 is quickly restored, and at the 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, and the second telescopic rod contracts and drives the mounting rod 16 to move together, and at the 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 receives the impact force in the horizontal direction, 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 impact force in the horizontal direction; as the working time is accumulated, the surface of the striking rod 17 is gradually deformed by striking, so that a worker can rapidly remove the damaged striking rod 17 from the mounting rod 16 by screwing the screw 20 and replace the striking rod 17 by the communicating pipe 21.
In the initial state, the second pneumatic telescopic rod 25 is in the contracted state; in the working process, the extrusion plate 15 intermittently extrudes the elastic block 14, when the elastic block 14 is extruded, part of gas in the second cavity 34 flows into the fifth cavity 37 along the fourth air pipe 29, at the moment, the gas 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 the moment, the second pneumatic telescopic rod 25 stretches and drives the first magnet 26 to move downwards, in the process of moving downwards the first magnet 26, under the attraction force of the first magnet 26 and the second magnet 27, the second magnet 27 drives the scraping plate 24 to move downwards along with the first magnet 26, in the process of moving downwards the scraping plate 24, the powder attached to the surface of the first grinding roller 3 is cleaned by the scraping plate 24, so that the surface of the first grinding roller 3 can be kept in a rough state, 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 a worker needs 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 to pollute the outside, the gas circulation needs to be stopped when the feed is added; when the worker adds the fodder, the worker rotates the upper cover 32, and at this time, the upper cover 32 is out of contact with the switch 31, so that the solenoid valve 30 is powered off, and at this time, the circulation pipe 12 is in a blocking state with the case 1, so that when the worker adds the fodder, the circulation of the air flow in the case 1 is stopped, and thus the leakage of the air containing the fodder powder to the outside can be prevented.
