A vibrating screen device for grading and screening pellet feed

Abstract

This application provides a vibrating screen device for grading and screening pelleted feed, relating to the field of feed grading and screening technology. It includes a fixed base, a pelleted feed vibrating screening and collection component, and a first motor that drives a drive shaft and a conveyor auger to rotate. The conveyor auger, upon rotation, lifts the material and feeds it through an inclined discharge pipe. The material is guided by a discharge guide plate to the center of the crushing roller, where a second motor drives the crushing roller to crush the pelleted material. The crushed material falls onto multiple screening plates for screening. A striking wheel, upon rotation, strikes the screening box. Under pressure, the screening box vibrates up and down through the cooperation of springs and limit blocks, causing the pelleted feed above the screening plates to vibrate, thus preventing accumulation and blockage during screening.

Description

Technical Field

[0001] This utility model relates to the field of feed grading and screening technology, and in particular to a vibrating screen device for grading and screening pellet feed. Background Technology

[0002] Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed mainly refers to the food raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed ingredients such as soybeans, soybean meal, corn, fishmeal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Pelleted feed is favored by aquaculture farmers due to its comprehensive nutrition, high stability, resistance to water breakdown and pollution, easy digestibility and absorption, and labor-saving benefits. Existing grading and screening devices leave larger feed particles that fail to pass the screening process above multiple grading and screening screens. This requires workers to disassemble the side panels of the device, remove the large feed particles, collect them, and crush them again. The operation process is cumbersome and significantly reduces work efficiency. Therefore, we have proposed a vibrating screen device for grading and screening feed particles.

The supporting slide rod 14 is fixedly installed on the top of the limiting block 13, and the screening box 15 is fixedly installed on the top of the supporting slide rod 14.

[0018] In this embodiment, a conveying screw 8 is fixedly installed on the outside of the drive shaft 7, a feeding pipe 9 is fixedly installed on the outside of the first fixed cylinder 5, and a pellet feed grading and screening component 2 is provided on the pellet feed vibrating screen collecting component 1.

[0019] In this embodiment, the pellet feed vibrating screening and collecting assembly 1 further includes a mounting plate 16, a rotating shaft 17, a bevel gear 18, and an impact wheel 19. The mounting plate 16 is fixedly installed on the top left and right sides of the fixed base 3. The rotating shaft 17 is rotatably installed on the inner side of the mounting plate 16.

The impact wheel 19 is fixedly installed on the outer side of the rotating shaft 17 and abuts against the screening box 15.

[0020] In this embodiment, the pellet feed grading and screening assembly 2 includes a screening plate 21, a feeding guide plate 22, a second motor 23, and a crushing roller 24. The two screening plates 21 are fixedly installed between the inner walls of the front and rear sides of the screening box 15, the feeding guide plate 22 is fixedly installed on the inner side of the screening box 15, the two second motors 23 are fixedly installed on the front side of the screening box 15, and the crushing roller 24 is fixedly installed at the output end of the second motor 23.

[0021] In this embodiment, the pellet feed grading and screening assembly 2 also includes a discharge chute 25 for unscreened pellets, a collection hopper 26, an electric slide rail 27, an electric slider 28, and a movable collection box 29. The discharge chute 25 for unscreened pellets is located on the upper and lower left sides of the screening box 15. The collection hopper 26 is fixedly installed on the top of the storage box 4 and on the left side of the screening box 15. The electric slide rail 27 is fixedly installed on the front and rear left sides of the screening box 15. The electric slider 28 is slidably installed on the outside of the electric slide rail 27.

The discharge chute 25 for unscreened pellets is connected to the screening plate 21, allowing unscreened material above the inclined screening plate 21 to be discharged through the discharge chute 25.

[0022] In this embodiment, the hopper 26 is trapezoidal in shape, and two triangular guide blocks are provided inside the hopper 26. The electric slider 28 moves above the electric slide rail 27, thereby opening the discharge chute 25 for unscreened particles, allowing the unscreened feed above the screening plate 21 to enter the hopper 26. The hopper 26 can guide the feed and let it fall into the storage box 4 for further cyclic crushing and screening, making the device highly efficient and eliminating the need for manual cleaning and collection of feed.

[0023] In this embodiment, the striking wheel 19 is elliptical in shape and made of rubber. While the drive shaft 7 is rotating, it can drive the rotating shaft 17 and the striking wheel 19 to rotate through the bevel gear 18. After rotating, the striking wheel 19 can strike the screening box 15. After being subjected to force, the screening box 15 can shake up and down through the cooperation of the spring 12 and the limiting block 13, thereby causing the granular feed above the screening plate 21 to vibrate, so that the feed will not accumulate and block during the screening process. The rubber striking wheel 19 can deform during the striking process, so as not to damage the screening box 15.

[0024] In this embodiment, a sliding groove is provided at the bottom of the screening box 15, and the movable collection box 29 fits into the sliding groove. Multiple pulleys are rotatably installed at the bottom of the movable collection box 29.

Multiple pulleys are provided above the movable collection box 29, and a braking device is provided above the pulleys. The pulleys and the braking device are existing technologies, so they are not described in detail in this utility model.

[0025] The specific operation is as follows: the pelleted feed to be screened is placed inside the storage bin 4, and the first motor 6 drives the drive shaft 7 and the conveying screw 8 to rotate. After the conveying screw 8 rotates, it can lift the material and feed it through the inclined feeding pipe 9. The material can be guided by the feeding guide plate 22 to the middle of the crushing roller 24, so that the second motor 23 can drive the crushing roller 24 to crush the pelleted material. The crushed material falls above the multiple screening plates 21 for screening. While the drive shaft 7 is rotating, it can drive the rotating shaft 17 and the striking wheel 19 to rotate through the bevel gear 18. After the striking wheel 19 rotates, it can strike the screening box 15. After being subjected to force, the screening box 15 can shake up and down through the cooperation of the spring 12 and the limit block 13, so that the material above the screening plate 21 can be screened. The pelleted feed is vibrated to prevent accumulation and blockage during screening. The screened material falls into the movable collection box 29 for collection. Multiple pulleys are installed on top of the movable collection box 29, and a braking device is installed on top of the pulleys. The pulleys and braking device are existing technologies, so they are not described in detail in this utility model. The screening plate 21 is inclined. After screening, the electric slider 28 can be controlled to move above the electric slide rail 27, thereby opening the discharge chute 25 for unscreened pellets. This allows the unscreened feed above the screening plate 21 to enter the collection hopper 26. The collection hopper 26 can guide the feed and let it fall into the storage box 4 for further recycling, crushing, and screening. This makes the device highly efficient and eliminates the need for manual cleaning and collection of feed.
