[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc. Feed pellets are feed processed into granular form to facilitate feeding by staff and eating by animals. In the process of processing feed pellets, both the raw materials and the formed feed pellets need to be screened.

[0003] The existing feed screening device generally screens the feed through a filter plate, and during the screening process, a vibration motor is generally used to vibrate the filter plate to improve the screening efficiency of the filter plate.

For example, "connected" can be a fixed connection, welding, riveting, bonding, etc., or a detachable connection, threaded connection, key connection, pin connection, etc., or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0022] like Figure 1-4As shown, a feed particle screening device proposed by the utility model comprises a workbench 1, the upper end surface of the workbench 1 is rotatably connected to a screening barrel 2 with one end extending thereunder, a screening component 3 is provided below the screening barrel 2, a driving component 4 for driving the screening barrel 2 to rotate is provided above the workbench 1, an output end of the driving component 4 is connected to the screening barrel 2, a toggle component 5 is provided above the workbench 1, and four evenly distributed support columns 6 are provided on the lower end surface of the workbench 1.

[0023] In the utility model, the raw materials or feed particles inside the screening barrel 2 can be screened through the screening barrel 2 and the screening component 3, and the screening barrel 2 and the screening component 3 can be driven to rotate by the driving component 4, so that the movement amplitude of the screening barrel 2 and the screening component 3 is increased, and the screening efficiency of the screening device is improved. When the screening barrel 2 and the screening component 3 rotate, the raw materials or feed particles inside can be moved by the toggling component 5, and the screening efficiency of the screening device is further improved. The support column 6 can stably support the workbench 1.

[0024] In an optional embodiment, the screening component 3 includes a filter plate 31 and two connecting components 32. The filter plate 31 is arranged below the screening barrel 2. The upper end surface of the filter plate 31 contacts the lower end surface of the screening barrel 2. The two connecting components 32 are both arranged on the outside of the screening barrel 2 and are axially symmetrically distributed.

[0025] It should be noted that the filter plate 31 can be fixed to the bottom of the screening barrel 2 through two connecting components 32, so that the screening barrel 2 and the filter plate 31 form a whole, and by placing the raw materials or feed particles inside the screening barrel 2, the raw materials or feed particles can be screened through the filter plate 31.

[0026] In an optional embodiment, the connecting assembly 32 includes a connecting block 321 and a connecting bolt 322. The connecting block 321 is arranged on the outside of the screening barrel 2. The connecting bolt 322 passes through the connecting block 321 and extends to the inside of the filter plate 31. The connecting bolt 322 is threadedly connected to the filter plate 31.

[0027] It should be noted that, by rotating the connecting bolt 322 with a tool, when the connecting bolt 322 is disengaged from the filter plate 31, the filter plate 31 can be removed, so that a new filter plate 31 can be installed. By replacing the filter plate 31, during the pellet feed production process, both the raw materials and the pellet feed can be screened by a screening device, and at the same time, feed particles of different particle sizes can also be screened.

[0028] In addition, after the screening is completed, the filter plate 31 can be disassembled to clean the filter plate 31 and discharge the raw materials and feed particles that have not passed the screening.

[0029] In an optional embodiment, the driving assembly 4 includes a driven gear ring 41, a driving gear 42, a driving motor 43 and a rotating shaft 44. The driven gear ring 41 is arranged on the outside of the screening barrel 2, the driving gear 42 is arranged above the workbench 1, the driven gear ring 41 is meshed with the driving gear 42, the driving motor 43 is arranged on the lower end surface of the workbench 1, one end of the rotating shaft 44 is arranged on the output shaft of the driving motor 43, and the other end of the rotating shaft 44 passes through the workbench 1 and is connected to the lower end surface of the driving gear 42.

[0030] It should be noted that by starting the drive motor 43, the output shaft of the drive motor 43 will drive the rotating shaft 44 to rotate, the rotating shaft 44 will drive the driving gear 42 to rotate, and the driving gear 42 will drive the driven gear ring 41 meshing therewith to rotate, and the driven gear ring 41 will drive the screening barrel 2 to rotate. Under the action of the connecting component 32, the screening barrel 2 will drive the filter plate 31 to rotate, ensuring that the movement amplitude of the filter plate 31 is further increased, thereby further improving the screening efficiency of raw materials or feed particles.

[0031] In an optional embodiment, the toggle assembly 5 includes a vertical plate 51, a horizontal plate 52, a connecting column 53 and a plurality of toggle plates 54. The vertical plate 51 is arranged on the upper end surface of the workbench 1, the horizontal plate 52 is arranged on the outer end surface of the vertical plate 51 and is located above the screening barrel 2, one end of the connecting column 53 is arranged on the lower end surface of the horizontal plate 52, and the other end of the connecting column 53 is located inside the screening barrel 2 and at the center of the screening barrel 2. A plurality of toggle plates 54 are evenly arranged on the outer surface of the connecting column 53, and the lower end surfaces of the plurality of toggle plates 54 are all slidably connected to the upper end surface of the filter plate 31.

[0032] It should be noted that, because the toggle assembly 5 is arranged on the upper end surface of the workbench 1, the toggle assembly 5 will not rotate, thereby ensuring that the multiple toggle plates 54 will not rotate. However, when the filter plate 31 rotates, the raw materials or feed particles above it will rotate with the filter plate 31, and the raw materials or feed particles can be toggled by the relatively stationary multiple toggle plates 54, so that the raw materials or feed particles and the filter plate 31 move relative to each other, thereby further improving the screening efficiency of the screening device.

[0033] In this embodiment, the drive motor 43 is a DC motor, and the drive motor 43 is electrically connected to an external power supply and a controller. The drive motor 43 can be powered by an external power supply, and can be controlled by an external controller.

[0034] Working principle:

[0035] When the screening device for feed particles is used, the raw materials or feed particles are placed inside the screening barrel 2, and then the driving motor 43 is started. The output shaft of the driving motor 43 drives the rotating shaft 44 to rotate, and the rotating shaft 44 drives the driving gear 42 to rotate, and the driving gear 42 drives the driven gear ring 41 meshed therewith to rotate, and the driven gear ring 41 drives the screening barrel 2 to rotate. Under the action of the connecting component 32, the screening barrel 2 drives the filter plate 31 to rotate, ensuring that the movement amplitude of the filter plate 31 is further increased, thereby improving the screening efficiency of the raw materials or feed particles. While rotating and screening, the raw materials or feed particles can be toggled by a plurality of relatively stationary toggling plates 54, so that the raw materials or feed particles and the filter plate 31 move relative to each other, thereby further improving the screening efficiency of the screening device. After the screening is completed, the connecting bolt 322 is rotated by a tool. When the connecting bolt 322 is disengaged from the filter plate 31, the filter plate 31 can be removed, which is convenient for replacing the filter plate 31, and the raw materials and feed particles that have not passed the screening can also be discharged.
