Technical Field

[0001] The utility model relates to the technical field of impurity removal devices, in particular to a nut screening and impurity removal device. Background Art

[0002] There are many kinds of nuts. Many nuts are spherical, such as hazelnuts, walnuts and macadamia nuts. They have high nutritional value and are loved by people. After these spherical nuts are collected, there will be certain impurities mixed in, and they need to be removed. Nut screening and impurity removal equipment is needed.

[0003] For example, Chinese patent CN220496996U discloses a nut screening and impurity removal device, which includes a screening box, a door and a feeding hopper on the top. A plurality of cross bars are fixedly installed on the inner walls of both sides of the screening box, and a plurality of rings are movably sleeved on the cross bars. An inclined rod is fixedly installed on the side of the ring. A plurality of side openings are symmetrically opened on the adjacent two sides of the screening box, and a plurality of strips are also fixedly installed on both sides of the screening box. The scheme can drive the side plates to rotate by starting the motor to control the unloading speed. The nuts can be screened after passing through the inclined rods. The larger nuts can be guided to the corresponding side openings, and the smaller nuts can be screened again by the inclined rods below. Nuts of different volumes can be screened. The gap between the adjacent inclined rods below is smaller than the gap above. The debris can fall into the top of the receiving plate and slide down. The material can be discharged from both sides and can be piled up to improve the quality.

[0004] Although the above patent can screen nuts of different sizes, the gap between adjacent inclined bars at the bottom is smaller than the gap at the top, and debris can fall to the top of the receiving plate and slide down, and can be discharged from both sides and piled up to improve quality, but in this patent, the upper and lower inclined bars are in a stationary state during screening, the screening fluidity is general, and blockage is prone to occur.
