Description

A peanut multi-stage screening device

Technical Field

The utility model relates to the technical field of peanut processing, in particular to a multi-stage screening device for peanuts.

Background Art

Peanuts, formerly known as groundnuts, are a kind of nut that is abundant in production and widely consumed in my country. In addition to full peanuts, there are also some smaller ones and some relatively shriveled ones. When processing peanuts, vibrating screens and other screening devices are usually used to grade and screen peanuts of different sizes to screen out peanuts of different qualities.

An existing peanut vibrating screen usually has multiple screens inside for multi-level screening, and the screens are usually installed in the vibrating screen by bolt connection. When people need to dismantle and replace the screens in the middle or inside of the vibrating screen, due to the cramped internal space of the peanut vibrating screen, it is often necessary to remove the top screen first before dismantling the screens in the middle or inside. It is also necessary to rotate the bolts back and forth during disassembly, which is time-consuming and inconvenient.

The screen can be disassembled by pulling up the L-shaped rod and pulling down the screen. When the screen is disassembled and replaced, the surrounding screens cannot be disassembled, and there is no need to rotate the bolts back and forth for disassembly and assembly, which is more convenient and quick.

2. By controlling the movement of the adjustment plate in the feed hopper, the flow rate of the feed hopper to the vibrating screen body can be controlled to prevent the vibrating screen body from feeding too much and too quickly, causing a large amount of peanuts to accumulate on the screen and reduce the screening effect. People only need to shake the handle to control the flow rate of peanuts in the feed hopper, which is convenient and practical, and the support rod can support the adjustment plate to improve the stability of the movement of the adjustment plate in the feed hopper.

In conjunction with the connection of the rotating block 53, the adjustment plate 6 can be driven to move to control the peanut flow in the feed hopper 11.

The implementation principle of a peanut multi-stage screening device according to the embodiment of the utility model is:

When in use, peanuts of different particle sizes can be graded and vibrated and screened through the screening and filtration of the multiple screens 2 and the vibration of the vibrating screen body 1, thereby removing small impurities such as broken soil blocks in the peanuts and collecting different peanut particles.

When people need to disassemble and replace the screen 2, they pull up the L-shaped rod 43 to make the magnet block 42, the counterweight block 41 and the pin rod 4 rise together, so that the bottom end of the pin rod 4 is separated from the screen 2. At this time, the screen 2 will be unfixed, and then people pull down the screen 2 from the bottom of the vibrating screen body 1, and the screen 2 will slowly separate from the iron fixing frame 3 and the U-shaped plate 31 to disassemble the screen 2.

Then people can insert another screen 2 into the iron fixing frame 3 and the U-shaped plate 31, and then lower the L-shaped rod 43. After the pin rod 4 falls, it will be inserted into the fixing holes of the iron fixing frame 3 and the screen 2 to fix the screen 2, thereby completing the replacement process of the screen 2.

When people shake the handle 52, the threaded rod 51 will be driven to rotate and move laterally, and the connection with the rotating block 53 can drive the adjustment plate 6 to move. After the adjustment plate 6 moves, the shielding area in the feed hopper 11 can be controlled, thereby controlling the peanut flow rate of the feed hopper 11 to the vibrating screen body 1.
