[0002] In the eel farming industry, the uniformity of eel feed pellet size directly affects the feeding efficiency and growth status of eels. Therefore, precise grading of pellets is necessary during feed production.

[0003] Currently, eel feed screening largely relies on traditional vibrating screen equipment. This type of equipment mainly uses a single vibrating motor to drive the screen movement to achieve particle separation. However, traditional equipment lacks a real-time cleaning mechanism. Eel feed particles often get stuck in the screen holes due to their moisture and stickiness, causing the screen blockage to gradually worsen over time. This not only significantly reduces screening efficiency but also requires frequent shutdowns to clean the screen, increasing production downtime and labor costs. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screening device for eel feed production. The device uses a drive component to move a scraper along the groove of a rectangular plate to scrape off feed stuck in the screen holes. In conjunction with the cleaning and knocking components on the lower side of the sliding component, the screen is cleaned in real time, reducing the amount of feed particles clogging the screen holes and thus reducing screening efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A vibrating screening device for eel feed production includes a housing. A vibrating motor and four return springs are fixedly connected to the lower side of the housing. Support legs are fixedly connected to the lower ends of the four return springs. A first discharge port and a second discharge port are opened on the right side of the housing.

A scraper is fixedly connected to the sliding bracket, with the lower end of the scraper abutting against the upper end of the screen. A connecting block is fixedly connected to the sliding bracket, and the connecting block is connected to the driving component for transmission.

[0009] Furthermore, the driving component includes a servo motor fixedly connected to the left side of the housing, and a screw movably disposed on the housing; a round rod is fixedly connected to the inner wall of the housing, the screw and the round rod are parallel to each other, a connecting block slides laterally on the round rod, the connecting block is threadedly connected to the screw, and the output end of the servo motor is fixedly connected to one end of the screw.

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-6As shown, a vibrating screening device for eel feed production includes a housing 1. A vibrating motor and four return springs are fixedly connected to the lower side of the housing 1. Support legs are fixedly connected to the lower ends of the four return springs. A first discharge port 4 and a second discharge port 6 are opened on the right side of the housing 1. A rectangular plate 11 is installed inside the housing 1. An installation groove is opened on the rectangular plate 11. A screen 5 is fixedly connected in the installation groove. The screen 5 is fixedly connected between the first discharge port 4 and the second discharge port 6. Two grooves are opened on the rectangular plate 11. Sliding parts are slidably connected in both grooves. Scraping parts are fixedly connected to the upper side of the two sliding parts. A driving part is fixedly connected to one side of the housing 1. One end of the driving part is connected to the scraping part. A cleaning part is installed on the lower side of the sliding part and is located below the screen 5. A knocking part is installed on one side of the cleaning part. In use, the device generates vibration through a vibration motor on the lower side of the housing 1. With the cooperation of four return springs, the housing 1 and the internal rectangular plate 11 and screen 5 vibrate at high frequency. When the eel feed to be screened is put into the housing 1, the vibration of the screen 5 achieves particle grading. Feed particles larger than the aperture of the screen 5 remain on the surface of the screen 5 and move towards the first discharge port 4 for discharge. Feed particles smaller than the aperture of the screen 5 pass through the screen 5 and fall below, and are finally discharged from the second discharge port 6. At the same time, the drive unit drives the scraper to slide along the groove of the rectangular plate 11 to scrape the feed stuck in the holes of the screen 5. With the help of the cleaning and knocking parts on the lower side of the sliding part, the screen 5 is cleaned in real time, reducing the decrease in screening efficiency caused by feed particles clogging the screen holes.

[0026] like Figure 3 , Figure 4 , Figure 5 As shown, the sliding component includes two sliders 12 and two slide rods 17. The two slide rods 17 are fixedly connected inside the two mounting slots, and the two sliders 12 are slidably connected to the outside of the two slide rods 17. In use, when the driving component rotates, it drives the sliders 12 to move. At that time, the sliders 12 slide along the axial direction of the slide rods 17, providing a stable moving track for the scraper above and the cleaning component below, reducing the possibility of deviation.

[0027] like Figure 3 , Figure 4 , Figure 5 As shown, the scraping component includes a sliding bracket 14, with both ends of the sliding bracket 14 fixedly connected to the upper sides of two sliders 12. A scraper 15 is fixedly connected to the sliding bracket 14, with the lower end of the scraper 15 abutting against the upper end of the screen 5. A connecting block 13 is fixedly connected to the sliding bracket 14, and the connecting block 13 is connected to the driving component for transmission. When the slider 12 moves along the sliding rod 17, driving the sliding bracket 14 and the scraper 15 to slide, the scraper 15 scrapes away large particles of feed remaining on the surface of the screen 5, reducing their accumulation and clogging of the screen holes. At the same time, the connecting block 13 transmits the power of the driving component to the sliding bracket 14, realizing the reciprocating motion of the scraping component, reducing material residue, and increasing the effective screening area of ​​the screen 5.

[0028] like Figure 2 , Figure 3 , Figure 4 As shown, the driving component includes a servo motor 2 fixedly connected to the left side of the housing 1, and a screw 3 movably mounted on the housing 1. A round rod 7 is fixedly connected to the inner wall of the housing 1, with the screw 3 and the round rod 7 running parallel to each other. A connecting block 13 slides laterally on the round rod 7 and is threadedly connected to the screw 3. The output end of the servo motor 2 is fixedly connected to one end of the screw 3. When the servo motor 2 drives the screw 3 to rotate, the connecting block 13 reciprocates along the axial direction of the round rod 7 under the action of the screw 3's thread, thereby driving the scraper to move synchronously. During the movement, the round rod 7 limits the connecting block 13, ensuring that the scraper moves only in a straight line.

[0029] like Figure 3 , Figure 4 , Figure 5 As shown, the cleaning component includes two mounting plates, both of which are fixedly connected to the lower side of the two sliders 12. A brush 10 is rotatably connected between the two mounting plates. Gears 20 are fixedly connected to both sides of the brush 10. Racks 16 are fixedly connected to the lower front and rear ends of the rectangular plate 11. The racks 16 are meshed with the gears 20. When the mounting plates on the lower side of the sliders 12 move synchronously with the sliders, they will drive the brush 10 to slide on the lower surface of the screen 5. The gears 20 on both sides of the brush 10 mesh with the racks 16 at the lower end of the rectangular plate 11. During the movement, the gears 20 rotate and drive the brush 10 to rotate, thus removing the fine feed particles attached to the lower surface of the screen 5.

[0030] like Figure 4 , Figure 5 , Figure 6 As shown, the striking component includes a frame 19, which is fixedly connected to one side of the mounting plate. One side of the frame 19 is open. A rotating roller 18 is rotatably connected inside the frame 19. A lever 21 is fixedly connected to the lower side of the rotating roller 18. One side of the gear 20 is connected to the lever 21 for transmission. A rubber ball 22 is fixedly connected to the upper side of the rotating roller 18. When the gear 20 meshes with the rack 16 and rotates, the teeth of the gear 20 actuate the lever 21 inside the frame 19, causing the rotating roller 18 to rotate up and down. The rubber ball 22 on the rotating roller 18 strikes the lower surface of the screen 5 as it rotates, causing the stubborn particles embedded in the screen holes to loosen and fall off.

[0031] like Figure 4 , Figure 5 As shown, a folding cover plate 8 is slidably connected inside the mounting groove. One end of the folding cover plate 8 is fixedly connected to the inner wall of the mounting groove, and the other end is fixedly connected to one end of the slider 12. When the slider 12 moves, it causes the folding cover plate 8 to unfold, blocking the opening of the groove of the rectangular plate 11 and reducing the impact of feed particles falling into the groove on the movement of the sliding parts.

[0032] like Figure 2As shown, an inclined plate 9 is fixedly connected to the floor inside the housing 1. One side of the inclined plate 9 is flush with one side of the second discharge port 6. In use, the inclined plate 9 inside the housing 1 is set at an angle. Its high end receives the fine feed particles that pass through the screen 5, and its low end is flush with the second discharge port 6. The fine particles are quickly discharged by gravity, reducing the accumulation of feed particles at the bottom of the housing 1.

[0033] The working principle of this utility model is as follows: When in use, the device generates vibration through the vibration motor on the lower side of the housing 1. With the cooperation of four return springs, the housing 1 drives the internal rectangular plate 11 and screen 5 to vibrate at high frequency. When the eel feed to be screened is put into the housing 1, the vibration of the screen 5 achieves particle grading. Feed particles larger than the aperture of the screen 5 remain on the surface of the screen 5 and move towards the first discharge port 4 for discharge. Feed particles smaller than the aperture of the screen 5 pass through the screen 5 and fall below, and are finally discharged from the second discharge port 6. At the same time, the driving component drives the scraping component to slide along the groove of the rectangular plate 11 to scrape the feed stuck in the holes of the screen 5. With the help of the cleaning component and the knocking component on the lower side of the sliding component, the screen 5 is cleaned in real time, reducing the feed particles from clogging the screen holes and causing a decrease in screening efficiency.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
