Description

Technical Field

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

[0002] Leeches are omnivorous animals, primarily feeding on the blood and body fluids of animals. They also consume plankton and insects in the water. To ensure a balanced diet, artificially raised leeches need to be supplemented with easily digestible and nutrient-rich artificial feed. Feed particles vary in size and may contain impurities. Screened feed is generally easier for leeches to digest and absorb, thus improving feed utilization. This not only reduces feed waste but also lowers farming costs. Therefore, a screening device is needed to process the leech feed. During operation, the device vibrates up and down to screen the feed. The finished feed is then fed into containers placed on the ground. When a container is full, it needs to be replaced with an empty one. During this replacement process, the device continuously feeds the leech feed, causing a significant amount of feed to spill outside the containers, resulting in waste. Utility Model Content

The first discharge cylinder 56 is slidably connected to the inner wall above the second discharge cylinder 92.

[0024] Working principle: During operation, the operator pours the feed into the inlet 4, and the feed enters the screen 51 through the inlet 4. The screen 51 vibrates up and down during operation. The up and down vibration of the screen 51 is existing technology and not the focus of this utility model. It is the common type of vibrating screening machine on the market. Therefore, the structure and working method of driving the screen 51 to vibrate up and down will not be described in detail here. After the feed falls into the screen 51, it is vibrated up and down. Some of the qualified-sized feed will fall into the discharge box 53 below through the screen 51. The remaining large pieces of feed that do not fall in are discharged from the first discharge port 52 of the screen 51 and fall into the first receiving bucket 8. The dust collector 64 is turned on. Dust generated during the up-and-down shaking of the screen 51 is sucked into the dust suction pipe 63 through the dust suction port 62 connected to the bracket 61, and flows into the dust collector 64. Qualified feed, after being shaken again in the discharge box 53, slides into the inclined connecting cylinder 55. Two inclined blocks 54 are provided on both sides of the discharge box 53 to prevent feed from falling into the corners and failing to discharge. The connecting cylinder 55 of the discharge box 53 has an enclosed design to prevent feed from flying out of the device when discharged. When the second receiving bucket 11 is placed on top of the lifting platform 916, the lifting platform 916 descends due to the weight of the second receiving bucket 11. During the descent of the lifting platform 916, it drives the connected second rack 9. 15 moves downwards, and the second rack 915 meshes with the second gear 914. When the second rack 915 moves downwards, it drives the meshing second gear 914 to rotate clockwise. The second rotating shaft 913, which is bolted to the second gear 914, is driven to rotate. The second pulley 911, which is bolted to the second rotating shaft 913, drives the first pulley 910 through the belt. The first rotating shaft 98, which is bolted to the first pulley 910, rotates clockwise under its influence, which in turn drives the first gear 99 bolted to it. The first gear 99 meshes with the first rack 96. When the first gear 99 rotates clockwise, it drives the meshing first rack 96 to rotate clockwise. When the first rack 96 slides to the right, it drives the blocking plate 94. After leaving the second discharge cylinder 92, the spring 93 is compressed, and the feed enters the second receiving hopper 11 directly through the first discharge cylinder 56 and the second discharge cylinder 92. When the second receiving hopper 11 is almost full, it is taken out. Due to the lack of weight, the spring 93 of the lifting platform 916 is released, which drives the connected baffle plate 94 to slide into the second discharge cylinder 92. The feed falls into the second discharge cylinder 92 for temporary storage. After the second receiving hopper 11 is put back in, the baffle plate 94 is moved towards the third connecting plate 10 due to the contraction of the spring 93 and slides out of the second discharge cylinder 92. This reduces feed leakage and waste when changing feed.
