Description

Technical Field

[0001] This utility model belongs to the technical field of feed production equipment, and in particular relates to a screening device for crayfish feed production. Background Technology

[0002] With the rapid development of the crayfish farming industry, feed quality is crucial to the growth and farming efficiency of crayfish. In the crayfish feed production process, the raw materials are complex, the particle size varies after crushing, and there may be impurities. Since the quality of the feed is directly related to the growth rate and health of crayfish, screening devices play a vital role in the crayfish feed production process.

[0003] However, existing screening devices for crayfish feed production are not convenient for collecting larger feeds in a centralized manner, causing them to scatter in different areas of the screening device. This requires multiple manual cleaning and transportation, increasing the operational process and affecting overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a screening device for crayfish feed production. By setting up a collection section, it solves the problem that existing screening devices for crayfish feed production are not convenient for collecting larger feeds in a concentrated manner, causing them to be scattered in different areas of the screening device, requiring multiple manual cleaning and transfers, increasing the operation process, and affecting the overall production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a screening device for crayfish feed production, comprising a screening box, and further comprising: a main body mounted on the screening box for screening crayfish feed; a collection part disposed inside the screening box for collecting larger feed particles; and a screening unit disposed on the screening box and cooperating with the main body to distribute the feed evenly on the main body. After the crayfish feed is poured into the main body, the screening unit is activated to distribute the crayfish feed evenly on the main body for easy screening. After screening, the collection part collects the larger feed particles.

[0007] Furthermore, the main body includes a cover hinged to the outer wall of the screening box, a storage box fixedly connected to the outer wall of the screening box, and a sieve plate fixedly connected to the inner wall of the screening box; wherein, the storage box is used to store larger feed, and the sieve plate is used to screen the feed.

[0008] Furthermore, the collection section includes a threaded assembly fixed to the inner wall of the screening box for controlling the opening and closing of the collection section; and a sliding assembly mounted on the threaded assembly for restricting the threaded assembly; wherein, when the threaded assembly is rotated, the threaded assembly is restricted by the sliding assembly, thereby opening and closing the collection section to facilitate the centralized collection of larger feed after screening.

[0009] Furthermore, the screening unit includes a drive assembly mounted on the screening box to provide the necessary power output to the screening unit; and a scraping assembly mounted on the drive assembly to scrape and agitate the feed; wherein, when the drive assembly is activated, the drive assembly transmits power to the scraping assembly to scrape and agitate the feed, ensuring that the feed is evenly distributed within the device.

[0010] Furthermore, the threaded assembly includes a support frame fixedly connected to the inner wall of the screening box, a threaded rod passing through the support frame, the threaded rod being rotatably connected to the support frame, a handle fixedly connected to the top of the threaded rod, and a lifting block threadedly connected to the outer wall of the handle; wherein, the top of the support frame is tapered to prevent feed from accumulating on the support frame when pouring.

[0011] Furthermore, the sliding assembly includes several sliding rods fixedly connected to the bottom of the support frame. The bottom of each sliding rod passes through the lifting block, and the sliding rods are slidably connected to the lifting block. Several Z-shaped connecting rods are fixedly connected to the outer wall of the lifting block, and each Z-shaped connecting rod has an opening and closing component on the side away from the lifting block. The sliding rods are used to limit the lifting block. When the threaded rod rotates, the lifting block is restricted by the sliding rods, ensuring that the lifting block moves up and down with the rotation of the threaded rod.

[0012] Furthermore, the drive assembly includes a motor fixedly connected to the bottom of the screening box, the output shaft of the motor being fixedly connected to a rotating shaft via a coupling, the top of the rotating shaft extending into the screening box, the top of the rotating shaft penetrating the screen plate, and the rotating shaft being rotatably connected to the screen plate; wherein, when the motor is started, the rotating shaft transmits the rotational power of the motor to the scraping assembly.

[0013] Furthermore, the scraping assembly includes several scrapers fixedly connected to the outer wall of the rotating shaft, the bottom of each scraper being in contact with the screen plate, and several stirring rods fixedly connected to the outer wall of the rotating shaft; wherein, the rotation of the scrapers will cause the feed on the screen plate to be evenly distributed, and the rotation of the stirring rods will cause the feed with smaller particle size after filtration to be evenly distributed in the screening box, thus avoiding the accumulation of feed.

[0014] Furthermore, the opening and closing component includes several discharge troughs formed on the screening box, and a baffle is fixedly connected to the side of the Z-shaped connecting rod away from the lifting block. The baffle cooperates with the discharge troughs. During the screening process, the baffle is in a state of blocking the discharge troughs. When screening stops, the baffle opens, and larger particle sizes of feed flow into the storage box through the discharge troughs.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a collection section, after screening, the handle can be turned to drive the threaded rod to rotate. At this time, the lifting block will be restricted by the sliding rod. As the threaded rod rotates, it drives the Z-shaped connecting rod to move upward, which in turn drives the baffle to move upward until the baffle is separated from the discharge chute. Larger feed will fall into the storage box through the discharge chute. During this process, the centrifugal force generated by the rotation of the scraper will also accelerate the speed at which larger feed falls into the storage box. Larger feed can be collected in the storage box, avoiding the tedious operation of multiple manual cleaning and transfer, thereby shortening the production cycle, improving production efficiency, reducing unnecessary operation links, avoiding waste caused by scattering, and reducing production costs.

[0017] 2. By setting up a screening section, when feed screening is required, the motor can be started. The motor will drive the scraper to rotate through the shaft, scraping the feed on the screen plate. Larger particles will remain on the screen plate, while smaller particles will fall to the bottom of the screening box. As the shaft rotates, the stirring rod will also rotate, thus preventing smaller particles from accumulating in the screening box. When the scraper rotates, it applies mechanical force to the feed on the screen plate, pushing the feed to move on the screen plate surface, promoting full contact between the feed particles and the screen holes. This prevents large particles from clogging the screen holes due to accumulation, and allows small particles to pass through the screen holes faster, reducing retention and thus increasing the screening volume per unit time.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5As shown, this utility model is a screening device for crayfish feed production, including a screening box 111, and further including: a main body 1, which is installed on the screening box 111 and used to screen crayfish feed. The main body 1 includes a box cover 112 hinged to the outer wall of the screening box 111, a storage box 113 fixedly connected to the outer wall of the screening box 111, and a sieve plate 114 fixedly connected to the inner wall of the screening box 111; wherein, the storage box 113 is used to store larger feed, and the sieve plate 114 is used to screen the feed; a collection part 2, which is installed inside the screening box 111 and used to collect larger feed; and a screening part 3, which is installed on the screening box 111 and cooperates with the main body 1 to make the feed evenly distributed on the main body 1; wherein, after the crayfish feed is poured into the main body 1, the screening part 3 is activated to make the crayfish feed evenly distributed on the main body 1 to facilitate the screening of crayfish feed. After screening, the larger feed is collected by the collection part 2.

[0029] The collecting section 2 includes a threaded assembly 21 fixed to the inner wall of the screening box 111 for controlling the opening and closing of the collecting section 2; and a sliding assembly 22 mounted on the threaded assembly 21 for restricting the threaded assembly 21. When the threaded assembly 21 is rotated, it is restricted by the sliding assembly 22, thereby opening and closing the collecting section 2 to facilitate the centralized collection of larger feed after screening. The threaded assembly 21 includes a support frame 211 fixedly connected to the inner wall of the screening box 111, with the support frame 211 extending through... A threaded rod 212 is inserted, rotatably connected to a support frame 211. A handle 213 is fixedly connected to the top of the threaded rod 212, and a lifting block 214 is threadedly connected to the outer wall of the handle 213. The top of the support frame 211 is tapered to prevent feed from accumulating on it during feeding. The sliding assembly 22 includes several sliding rods 221 fixedly connected to the bottom of the support frame 211. The bottoms of each sliding rod 221 pass through the lifting block 214, and the sliding rods 221 are slidably connected to the lifting block 214. Several Z-shaped connecting rods 222 are fixedly connected to the outer wall, and each of the Z-shaped connecting rods 222 has an opening and closing component on the side away from the lifting block 214. A sliding rod 221 is used to limit the lifting block 214. When the threaded rod 212 rotates, the lifting block 214 is restricted by the sliding rod 221, ensuring that the lifting block 214 moves up and down with the rotation of the threaded rod 212. The opening and closing components include several discharge slots 223 formed on the screening box 111, and a baffle 224 is fixedly connected to the side of the Z-shaped connecting rod 222 away from the lifting block 214. The baffle 224 and the discharge chute 223 cooperate with each other. During the screening process, the baffle 224 is in a state of blocking the discharge chute 223. When screening stops, the baffle 224 opens, and the larger particles of feed flow into the storage box 113 through the discharge chute 223. By setting up the collection part 2, the larger particles of feed can be collected into the storage box 113, avoiding the tedious operation of multiple manual cleaning and transfer, thereby shortening the production cycle, improving production efficiency, reducing unnecessary operation links, avoiding waste caused by scattering, and reducing production costs.

[0030] The screening unit 3 includes a drive assembly 31, which is mounted on the screening box 111 to provide necessary power output to the screening unit 3; and a scraping assembly 32, which is mounted on the drive assembly 31 to scrape and agitate the feed. When the drive assembly 31 is started, it transmits power to the scraping assembly 32 to scrape and agitate the feed, ensuring uniform distribution within the device. The drive assembly 31 includes a motor 311 fixedly connected to the bottom of the screening box 111. The output shaft of the motor 311 is fixedly connected to a rotating shaft 312 via a coupling. The top of the rotating shaft 312 extends into the screening box 111, and the top of the rotating shaft 312 penetrates the screen plate 114, with the rotating shaft 312 rotatably connected to the screen plate 114. When the motor 311 is started, the rotating shaft 312 transmits the rotational power of the motor 311. The feed is transmitted to the scraping assembly 32, which includes several scrapers 321 fixedly connected to the outer wall of the rotating shaft 312. The bottom of each scraper 321 is in contact with the screen plate 114. Several stirring rods 323 are fixedly connected to the outer wall of the rotating shaft 312. The rotation of the scrapers 321 will make the feed on the screen plate 114 evenly distributed, and the rotation of the stirring rods 323 will make the feed with smaller particle size after filtration evenly distributed in the screening box 111, avoiding the accumulation of feed. By setting the screening part 3, when the scrapers 321 rotate, they apply mechanical external force to the feed on the screen plate 114, pushing the feed to move on the surface of the screen plate 114, so that the feed particles can fully contact the screen holes, thereby avoiding the large particles of feed from clogging the screen holes due to accumulation, and also allowing the small particles of feed to pass through the screen holes faster, reducing the retention phenomenon, thereby increasing the screening amount per unit time.

[0031] One specific application of this embodiment is as follows: In use, the crayfish feed to be screened is first poured into the screening box 111. The feed will be located on the sieve plate 114. When screening is required, the motor 311 can be started. The motor 311 will drive the scraper 321 to rotate via the rotating shaft 312, scraping the feed on the sieve plate 114. Larger particles will remain on the sieve plate 114, while smaller particles will fall through the sieve plate 114 to the bottom of the screening box 111. Since the stirring rod 323 also rotates when the rotating shaft 312 rotates, this prevents smaller particles from accumulating in the screening box 111 after screening. After completion, the handle 213 can be turned to drive the threaded rod 212 to rotate. At this time, the lifting block 214 will be restricted by the sliding rod 221. As the threaded rod 212 rotates, it drives the Z-shaped connecting rod 222 to move upward, which in turn drives the baffle 224 to move upward until the baffle 224 is separated from the discharge chute 223. The larger feed will fall into the storage box 113 through the discharge chute 223. During this process, the centrifugal force generated by the rotation of the scraper 321 will also accelerate the speed at which the larger feed falls into the storage box 113. Then, open the box cover 112, take out the smaller feed particles, and then take out the larger feed particles from the sieve plate 114.
