[0002] In modern cattle and sheep breeding, feed is the most important resource. In order to make cattle and sheep grow faster and better, feed is often mixed with multiple ingredients, and after mixing, granulation is completed through wetting and drying.

[0003] Cattle and sheep feed is mainly grain. Grains are often mixed with sand and gravel during transportation and harvesting. At the same time, the grains contain some unfilled grains or rotten grains, which will affect the nutritional structure and taste of the feed. Therefore, at this stage, the screening and separation mainly adopts the method of air separation to target the different impurity densities of these common feeds.

[0004] However, in the modern air separation process, only sand and gravel with large density differences can be separated from grains, but bad grains in the grains cannot be effectively separated, resulting in the need for secondary separation after the separation is completed. The separation cannot be completed in one device, resulting in complex procedures and more equipment usage. In view of this, in-depth research on the above-mentioned problems led to the creation of this case. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides an implementation scheme: in the process of cattle and sheep breeding, feed is mainly grains. In order to improve the taste of feed and avoid affecting the intestines of animals, it is necessary to screen the grains for cattle and sheep breeding at this stage. The current grain screening mainly adopts wind selection, but wind selection can only separate sand and gravel with larger dead weight. The replaced grains need to be screened with supporting equipment, which not only increases the equipment cost, but also increases the complexity of the process.

[0023] According to the instruction manual Figure 1-3 It can be seen that in view of the above problems, the present application discloses a feed screening device for cattle and sheep breeding and processing, comprising a casing 1, a feeding port 2 is provided at one end of the casing 1, a discharge port 3 is provided at the corresponding end of the casing 1, a discharge port 4 is provided at the bottom of the casing 1, a pair of separation conveyor belts 5 are arranged in parallel on the discharge port 3, and a wind selection mechanism is provided between the discharge port 4 and the discharge port 3;

[0024] In the specific implementation process, the casing 1 is used as the main space for air separation, and the feeding port 2 at one end of the casing 1 is used for adding grains. After the grains are added into the casing 1 from the feeding port 2, they are sorted by the sorting mechanism on one side of the casing 1. The sorting is divided into two stages. The first stage is to sort sand and gravel, and the sand and gravel are discharged from the discharge port 4. The second stage is to screen unfull or diseased grains. After the second stage sorting, good grains and bad grains are respectively sent out from a pair of separation conveyor belts 5 on the discharge port 3. A throwing conveyor belt 12 is arranged below the feeding port 2. The material is firstly sent out horizontally through the throwing conveyor belt 12. The throwing conveyor belt 12 does not exceed the throwing separator 10. A guide roller 13 is arranged between the throwing conveyor belt 12 and the pair of separation conveyor belts 5, which is used to divert and guide the grains and sand and gravel separated once;

[0025] Specifically, according to the instructions Figure 1-3It can be seen that the above-mentioned air separation mechanism includes an air separation fan 6. The air separation fan 6 is arranged on one side of the casing 1. The air outlet of the air separation fan 6 is respectively connected to the first air supply pipe 7, the second air supply pipe 8 and the third air supply pipe 9. The first air supply pipe 7 extends to the bottom of the casing 1 and is connected to a throw-out separator 10. The throw-out separator 10 is provided with a plurality of air nozzles with their nozzles facing upward. A descending separator 11 is arranged on one side of a pair of separation conveyor belts 5. The descending separator 11 is also provided with a plurality of air nozzles. The air nozzles of the descending separator 11 face downward.

[0026] In the specific implementation process, the air separation fan 6 provides high-speed and high-pressure separation air, and the separation air is respectively sent to three different positions in the casing 1 from the first air supply pipe, the second air supply pipe 8 and the third air supply pipe 9. The first air supply pipe 7 first sends the air to the position of the throwing separator 10, and the air is blown upward through the throwing separator 10. The sand and gravel will not be disturbed by the weight problem and fall into the discharge port 4 under the action of the throwing conveyor belt 12, while the grains will fall into the separation due to the air supply of the throwing separator 10 over the guide roller 13. On one side of the conveyor belt 5, and then on one side of the separation drum, a downward separator 11 is provided to guide the grain to move downward toward the separation conveyor belt 5. Finally, an auxiliary separator 14 is connected to the third air supply pipe 9. The auxiliary separator 14 is provided with a plurality of air nozzles facing upward. The auxiliary separator 14 is used to perform secondary sorting of the grain. The wind force for sorting is less than the wind force for the primary sorting. The supporting effect of the tiny wind force affects the incomplete grains, so that the bad grains are blown to the upper separation conveyor belt 5.

[0027] As a preferred solution, further, a separator is connected to the air outlet of the air separation fan 6, and the separator is respectively connected to the first air supply duct 7, the second air supply duct 8 and the third air supply duct 9. The separator is used to divert the wind force generated by the air separation fan 6 and supply it to the first air supply duct 7, the second air supply duct 8 and the third air supply duct 9 respectively.

[0028] As a preferred solution, further, a separation regulating valve 15 is connected between the third air supply pipe 9 and the auxiliary separator 14 , and the wind force of the third air supply pipe 9 can be adjusted by the separation regulating valve 15 .

[0029] As a preferred solution, further, a pair of separation conveyor belts 5 are arranged in parallel and staggered, and the upper separation conveyor belt 5 is closer to the discharge port 3, providing a jumping distance for the bad grains.

[0030] As a preferred solution, further, a pair of separation conveyor belts 5 located at the discharge port 3 are matched with the end of the separation conveyor belt 5 near the bottom, and the good grains are sent to the other side through the diversion discharge trough 16 to avoid being mixed with the bad grains at the separation point again.

[0031] As a preferred solution, further, the directions of the ejection separator 10 and the downward separator 11 both have an angle with the horizontal.

[0032] From the above, it can be generally known that the feed screening device for cattle and sheep breeding and processing is designed with a three-channel air separator for separating cattle and sheep feed grains. The wind force generated by the air separation fan 6 is unified to supply air to three air supply ducts. After the first ventilation duct separates the sand and gravel from the grains, after being guided by the second ventilation duct, the auxiliary separator 14 connected to the third ventilation duct separates the bad grains in the grains, thereby reducing the number of supporting tools required and improving the screening efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
