Description

Technical Field

[0001] The utility model relates to the field of feed processing, in particular to a feed screening machine. Background Art

[0002] Feed is the general term for food for animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types 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.

[0003] China's authorized patent announcement number: CN 217569655 U records "a high-precision speed-adjustable feed screening machine", which adjusts the size of the gap between the screen frame and the adjustable screen by sliding the screen frame and the adjustable screen. After adjusting the position of the adjustable screen, the position of the adjustable screen is limited, so that the size of the screened particles can be accurately determined during feed screening, ensuring that feed of appropriate size passes through the adjustable screen and enters the upper end of the slope panel.

[0004] However, there are still the following defects and shortcomings in the application process:

[0005] When screening feed, any feed smaller than the holes in the screen will leak through, and the size of the leaked feed itself will also vary significantly, so the screening itself is relatively rough.

[0006] Therefore, it is necessary to provide a new feed screening machine to solve the above-mentioned technical problems. Utility Model Content

[0010] The number of adjustable screens is the same as that of the fixed screens and they are slidably connected to the fixed screens;

[0011] The adjusting component is installed on the fixed screen and the adjusting screen, and drives the adjusting screen to slide along the surface of the fixed screen through the adjusting component.

[0012] Preferably, the fixed screen is arranged obliquely, and the apertures of the screen holes of the fixed screen increase successively from the highest point to the lowest point.

[0013] Preferably, a plurality of vertically arranged partition plates are fixed on the mounting frame, and the upper ends of the partition plates are welded to the plate body between two adjacent fixed screens, and the interior of the mounting frame is divided into a plurality of independent spaces by the partition plates.

[0014] Preferably, a plurality of lower hoppers corresponding to independent spaces are fixed to the lower end of the mounting frame.

[0015] Preferably, an L-shaped limiting strip is welded to the upper end of the fixed screen, a slide groove is formed between the limiting strip and the fixed screen, and the adjustable screen slides inside the slide groove.

[0016] Preferably, the adjustment assembly includes a positioning seat welded to the upper end of the fixed screen and away from the center position, a tightening bolt with a rotatable connection passes through the positioning seat, and a connecting seat welded to the adjusting screen is also provided on one side of the positioning seat, and the tightening bolt extends into the interior of the connecting seat and is threadedly connected thereto.
