[0002] Low-protein pig feed, also known as "low-protein diet", is a type of feed widely used in the industry. Its core concept is to use relatively low-cost miscellaneous proteins (such as miscellaneous meal, by-products and other protein raw materials) and synthetic amino acids to replace high-cost conventional proteins (such as soybean meal, fish meal, etc.) to reduce feed costs. At the same time, through amino acid balance and protein utilization improvement technology, low-protein diets can maintain production performance comparable to high-protein diets.

[0003] The crushing of low-protein pig feed is an important part of the feed processing process. The purpose of crushing is to increase the surface area of ​​the feed, which is beneficial to the digestion and absorption of animals, and at the same time improve and enhance the processing performance of the material. For low-protein pig feed, due to the particularity of its composition and nutritional value, it is necessary to pay attention to keeping the nutrients of the feed from being lost during the crushing process, and avoid excessive water entering to cause feed deterioration.

[0025] Example

[0026] like Figure 1-4 As shown, the utility model provides a crushing mechanism for processing low-protein pig feed, including a box body 1, a feed port 2 is arranged on the top of the box body 1, and a feed hopper 3 is arranged above the feed port 2. A baffle 17 is arranged at the bottom of the feed hopper 3, and a rotating shaft 3 18 is fixedly connected to one side of the baffle 17, and a rotating motor 3 19 is fixedly connected to the end of the rotating shaft 3 18 through the box body 1. After starting the rotating motor 3 19, the baffle 17 can be rotated. When the pig feed poured into the box body 1 is sufficient, the baffle 17 is controlled by the rotating motor 3 19 to maintain a horizontal state to ensure that the pig feed cannot leak from the feed port 2. When the pig feed is too little, the baffle 17 is controlled to be tilted or vertical, so that the pig feed can enter the box body 1 through the feed hopper 3. An observation window is arranged on the outer surface of the box body 1, through which the crushing and screening conditions inside the box body 1 can be understood.

[0027] Two crushing rollers 4 are arranged inside the box 1, and a rotating shaft 1 5 and a rotating shaft 2 6 are fixedly arranged at the center of the crushing rollers 4, respectively. The rotating shaft 1 5 and the rotating shaft 2 6 pass through the box 1 and are respectively fixedly connected with a driving wheel 9 and a driven wheel 10, and the driving wheel 9 and the driven wheel 10 are meshed and connected, and the other end of the rotating shaft 1 5 passes through the box 1 and is fixedly connected with a rotating motor 1 11. Start the rotating motor 11 to drive the rotating shaft 1 5 and the driving wheel 9 to rotate, and the driving wheel 9 drives the driven wheel 10 to rotate. The driven wheel 10 rotates in opposite directions to the driving wheel 9, so the rotation directions of the two crushing rollers 4 are also opposite, thereby achieving the crushing of pig feed.

[0028] A filter screen 7 is arranged below the crushing roller 4, and both ends of the filter screen 7 are fixedly connected to the inside of the box body 1, and a collision block 8 is fixedly arranged at the bottom of the filter screen 7. A rotating motor 2 12 is arranged outside the box body 1, and a rotating rod 13 is fixedly connected to the output end of the rotating motor 2 12, and a fixed block 14 is arranged at the other end of the rotating rod 13 penetrating the box body 1, and a chute is arranged inside the fixed block 14, and a spring 15 is fixedly connected in the chute, and a slider 16 is fixedly connected at the other end of the spring 15, and the slider 16 is slidably connected to the fixed block 14, and the slider 16 is slidably connected to the collision block 8. The rotating motor 2 12 is started, and the rotating motor 2 12 drives the fixed block 14 to rotate through the rotating rod 13, so that the slider 16 also rotates with the fixed block 14, and when the slider 16 passes the collision block 8, it hits, and the impact vibrates the filter screen 7, and then the pig feed accumulated on the filter screen 7 falls to the bottom of the box body 1 through the vibration.

[0029] A discharge pipe 20 is provided on one side of the box body 1, and a valve 21 is provided on the discharge pipe 20. The bottom of the box body 1 is arranged in an arc structure, and the discharge pipe 20 is arranged on one side of the lowest point of the arc structure, so that the crushed feed can flow out through the discharge pipe 20.

The air pump 24 draws air from the inside of the box 1 into the dust box 23 through the air pipe 22, and dust generated by crushing pig feed enters the dust box 23 together with the air.

[0031] When the pulverizing mechanism for processing low-protein pig feed of the present embodiment is used, the rotating motor 3 19 is started to control the baffle 17 to rotate, and then the pig feed enters the interior of the box body 1 through the feed hopper 3, and is pulverized by the pulverizing roller 4. The pulverized pig feed falls on the filter screen 7, and the rotating motor 2 12 is started to make the slider 16 continuously hit the collision block 8, so that the pig feed accumulated on the filter screen 7 falls to the bottom of the box body 1, and at the same time, the air pump 24 is started to suck the dust inside the box body 1 into the dust collecting box 23, and the pig feed at the bottom of the box body 1 can flow out through the discharge pipe 20.

[0032] Therefore, the utility model adopts a pulverizing mechanism for processing low-protein pig feed with the above structure, which can clean the dust and ensure that the pig feed accumulated on the filter net after being pulverized can fall into the box body in time.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
