Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a raw material screening device for feed production. Background Technology

[0002] Feed is a general term for the food of all animals raised by humans. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Screening is the process of using a sieve to allow fine particles smaller than the sieve holes to pass through the sieve surface, while coarse particles larger than the sieve holes are retained on the sieve surface, thus completing the separation of coarse and fine materials. This separation process can be regarded as consisting of two stages: material stratification and fine particle screening. Material stratification is a condition for completing the separation, and fine particle screening is the purpose of the separation.

[0003] In the process of feed production, in order to ensure feed safety and improve feed quality, a screening device is needed to screen raw materials.

[0026] refer to Figure 3 The rotating assembly 402 includes a motor 402a, which is located on the back of the feed hopper 3. The output end of the motor 402a is fixedly connected to a first gear 402b. The bottom of the first gear 402b is meshed with a second gear 402c, and the right side of the second gear 402c is meshed with a third gear 402d. The inner walls of the second gear 402c and the third gear 402d are both fixedly connected to the surface of the magnetic rod 401.

[0027] As a technical optimization of this utility model, the rotation component 402 facilitates the rotation of the magnetic rod 401, enabling the magnetic rod 401 to adsorb metal debris inside the feed hopper 3.

[0028] refer to Figure 4 The filter assembly 503 includes a housing 503a, the surface of which is connected to the output end of the pipe 501, a dust bag 503b is provided inside the housing 503a, and a fan 503c is connected to the bottom of the housing 503a.

[0029] As a technical optimization of this utility model, the filter component 503 can be set to easily filter metal debris in the air and prevent metal debris from entering the interior of the fan 503c.

[0030] refer to Figure 4 The top of the box 503a is provided with a cover plate 6, the surface of the cover plate 6 is threadedly connected to the inner wall of the box 503a, the top of the surface of the dust bag 503b is fixedly connected with a frame 7, the surface of the frame 7 is slidably connected to the inner wall of the box 503a, and pressure blocks 8 are fixedly connected to both sides of the top of the frame 7, the top of the pressure blocks 8 is in contact with the bottom of the cover plate 6.

[0031] As a technical optimization of this utility model, the dust bag 503b inside the box 503a can be easily disassembled and replaced by the cover plate 6. The position of the dust bag 503b can be positioned by the pressure block 8 and the frame 7 to prevent the dust bag 503b from falling out of the box 503a.

[0032] refer to Figure 3 The surface of the motor 402a is covered with a protective shell 9, and the first gear 402b, the second gear 402c and the third gear 402d are all located inside the protective shell 9.

[0033] As a technical optimization of this utility model, the protective shell 9 can protect the motor 402a, the first gear 402b, the second gear 402c and the third gear 402d, preventing the first gear 402b, the second gear 402c and the third gear 402d from pinching the user when rotating.

[0034] refer to Figure 2 A bushing 10 is fitted on both the front and rear sides of the magnetic rod 401. The surface of the bushing 10 is fixedly connected to the inner wall of the feed hopper 3. A scraper 11 is provided on the top of the magnetic rod 401. The side of the scraper 11 near the feed hopper 3 is fixedly connected to the inner wall of the feed hopper 3.

[0035] As a technical optimization of this utility model, the position of the magnetic rod 401 can be limited by the bushing 10 to prevent the magnetic rod 401 from shifting or shaking during rotation. The scraper 11 can clean the metal debris on the surface of the magnetic rod 401.

[0036] The working principle and usage process of this utility model are as follows: When in use, the user pours the raw material into the inside of the feed hopper 3. When the raw material passes through the magnetic rod 401, the magnetic rod 401 will adsorb the metal impurities in the raw material to the surface, thus removing impurities from the raw material. The raw material after impurity removal enters the inside of the screening device 1 for screening. At this time, the output end of the motor 402a drives the first gear 402b to rotate counterclockwise. The counterclockwise rotation of the first gear 402b drives the second gear 402c and the third gear 402d to rotate relative to each other. The rotation of the second gear 402c and the third gear 402d drives the magnetic rod 401 to rotate. Then, the scraper 11 cleans the rotating magnetic rod 401, causing the metal impurities to detach from the magnetic rod 401. At the same time, the blower 503c sucks up the cleaned metal impurities through the box 503a, the pipe 501 and the collection cover 502. After passing through the collection cover 502 and the pipe 501, the impurities enter the dust bag 503b inside the box 503a for collection.

[0037] In summary, this raw material screening device for feed production uses an adsorption mechanism 4 to adsorb metal impurities in the raw materials inside the feed hopper 3, and then a collection mechanism 5 collects the metal impurities from the adsorption mechanism 4, preventing the metal impurities from mixing with the raw materials. This solves the problem that screening devices cannot remove metal impurities from raw materials during use, and that the mixing of metal impurities with raw materials can easily damage subsequent feed processing equipment and affect feed quality.
