Description

Technical Field

[0001] The utility model relates to the field of feed screening devices, in particular to a screening device for laying hen feed production. Background Art

[0002] The main components of chicken feed are moisture, crude protein, sugar, crude fat, minerals, vitamins, etc. Since the nutrition of chicken flocks comes from feed, they must regularly ingest certain nutrients to maintain life, grow healthily, and lay eggs normally. When formulating chicken feed, it mainly includes corn, millet, sorghum, barley, and then an appropriate amount of wheat bran, soybean cake, fish meal, shell powder, salt, additives, etc. The feed formula should be adjusted for each age stage and rationally matched to meet the growth nutrition requirements of each stage. During the chicken feed processing process, operations such as granulation, drying, and screening are required.

[0003] When screening feed, a conventional screening machine is often used to divide the feed into two sizes of particles through a sieve mesh. For example, the Chinese utility model patent discloses a feed screening and collecting device for organic chicken feed processing, with the publication number CN221157587U, which screens the feed through an inclined sieve plate. However, the screening process is a one-time operation. When the sliding speed of the feed on the sieve plate is too fast, small particle feed often has difficulty passing through the sieve holes and falling, resulting in more small particle feed still being mixed in the large particle feed after screening, and multiple repeated screenings are required. Content of the Utility Model

[0004] In order to solve the above-mentioned problems in the prior art, the utility model provides a screening device for laying hen feed production, with a simple and reasonable structural design, which can screen large particle feed multiple times and improves the screening effect.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: A screening device for laying hen feed production, comprising a chassis and a feed inlet; a feed inlet is provided at the top of the chassis; two inclined blanking pipes are provided below the left and right sides of the feed inlet, and the two blanking pipes gradually decrease from the middle of the chassis to the outside; a feeding mechanism is provided directly below the feed inlet. The feeding mechanism consists of a feeding pipe, a feeding shaft, and a motor. A longitudinally arranged feeding shaft is installed inside the feeding pipe. The top of the feeding shaft is connected to the top wall of the feeding pipe through a bearing, and the bottom of the feeding shaft is connected to the output shaft of the motor; openings are respectively provided at the top and bottom of the left and right side walls of the feeding pipe; the bottom of the feeding pipe is connected to the bottom of the chassis through a support shaft; electric telescopic rods are installed on the left and right side walls inside the chassis. There are also two inclined sieve plates inside the chassis. The two sieve plates are located on the left and right sides of the feeding pipe. The lower end of the sieve plate is hinged to the outer wall of the feeding pipe and corresponds to the opening area at the bottom of the feeding pipe. The upper end of the sieve plate is located above the electric telescopic rod and corresponds to the area below the blanking pipe; the two openings at the top of the feeding pipe communicate with the top openings of the corresponding two blanking pipes; two storage boxes are also provided inside the chassis, and the two storage boxes are respectively located below the two sieve plates.

[0006] The top of the feeding pipe is a conical structure that is narrower at the top and wider at the bottom. When the feed is poured from the feed inlet, this structure prevents the feed from remaining at the top of the feeding pipe.

[0007] A box door is hinged to the front side wall of the chassis at the position corresponding to the storage box. After opening the box door, the storage box can be accessed and the internal components can be assembled and disassembled.

[0008] The beneficial effects of the present utility model are as follows: The screening device for laying hen feed production has a simple and reasonable structural design. After the feed is input from the feed inlet, it will fall onto the sieve plate through the blanking pipe. Under the reciprocating knocking of the electric telescopic rod, the feed will gradually move downward into the feeding mechanism. During the downward movement, the small-particle feed will pass through the sieve plate and fall into the storage box, while the feeding mechanism will lift the feed into the blanking pipe and then fall onto the sieve plate again for screening; after multiple screenings, the large-particle feed and the small-particle feed can be fully separated.

[0013] In order to make the purpose, technical solution and advantages of the present utility model more clear and understandable, the following further details the present utility model in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0014] Refer to Figure 1-2 , this embodiment provides a screening device for laying hen feed production, including a chassis 1 and a feeding port 2; a feeding port 2 is provided at the top of the chassis 1; two inclined discharging pipelines 3 are communicated below the left and right sides of the feeding port 2, and the two discharging pipelines 3 gradually decrease from the middle of the chassis 1 to the outside; a material lifting mechanism 4 is provided directly below the feeding port 2, and the material lifting mechanism 4 is composed of a material lifting pipe, a material lifting shaft and a motor. A longitudinally arranged material lifting shaft is installed inside the material lifting pipe. The top of the material lifting shaft is connected to the top wall of the material lifting pipe through a bearing, and the bottom of the material lifting shaft is connected to the output shaft of the motor; openings are respectively provided at the top and bottom of the left and right side walls of the material lifting pipe; the bottom of the material lifting pipe is connected to the bottom of the chassis 1 through a support shaft 5; electric telescopic rods 6 are installed on the left and right side walls inside the chassis 1, and there are also two inclined sieve plates 7 inside the chassis 1. The two sieve plates 7 are located on the left and right sides of the material lifting pipe. The lower end of the sieve plate 7 is hinged to the outer wall of the material lifting pipe and corresponds to the opening area at the bottom of the material lifting pipe, and the upper end of the sieve plate 7 abuts above the electric telescopic rod 6 and corresponds to the area below the discharging pipeline 3; the two openings at the top of the material lifting pipe are communicated with the top openings of the corresponding two discharging pipelines 3; two storage boxes 8 for collecting small particle feed are also provided inside the chassis 1, and the two storage boxes 8 are respectively located below the two sieve plates 7.

[0015] Preferably, in order to prevent material accumulation at the top of the material lifting pipe, the top of the material lifting pipe is of a conical structure with a narrow top and a wide bottom. When the feed is poured from the feeding port 2, this structure makes the feed not remain at the top of the material lifting pipe.

[0016] Preferably, in order to access the storage box 8 and install and disassemble internal components, a box door 9 is hinged on the front side wall of the chassis 1 at the position corresponding to the storage box 8.

[0018] The working principle of this device is as follows: After the feed is put into the feeding port 2, it will fall on the top of the sieve plate 7 through the feeding pipe 3. Under the reciprocating knocking vibration of the electric telescopic rod 6, the feed will gradually move downward and enter the lifting pipe through the bottom opening of the lifting pipe. During the downward movement, the small-particle feed will pass through the sieve plate 7 and fall into the storage box 8, while the lifting shaft will lift the feed and enter the feeding pipe 3 again through the top opening, and then fall on the sieve plate 7 again for screening; after multiple screenings, the large-particle feed and the small-particle feed can be fully separated.
