Secondary screening device for almonds

Abstract

The invention discloses a secondary screening device for almonds. The secondary screening device for almonds comprises a screening box, a storage cone barrel is vertically and fixedly installed in thescreening box, and ribbon type stirring blades are fixedly installed on the surface of a stirring shaft and located inside the storage cone barrel; the left side wall of the screening box is providedwith a feed pipe communicating with the interior of the storage cone barrel; an L-shaped discharge baffle transversely penetrates through the lower portion of the storage cone barrel in a horizontalsliding mode; an inclined storage sloping plate is arranged at the bottom of the screening box; and the side wall of the lower right portion of the screening box extends rightwards to form a dischargepipe. The almonds inside the storage cone barrel are rotationally scattered through the ribbon type stirring blades and prevented from blocking the lower end of the storage cone barrel to cause discharge difficulty, an upper screening plate and a lower screening plate move left and right in a reciprocating mode through rotation of an incomplete gear, the almonds falling to the upper screening plate and the lower screening plate can be evenly spread, the almonds of proper sizes can penetrate through the upper screening plate and the lower screening plate, and the screening efficiency is effectively improved.

Description

technical field [0001] The invention relates to the mechanical technical field of screening devices, in particular to a secondary screening device for almonds. Background technique [0002] Almonds, also known as apricots, muluozi, etc., the almond fruit grows on a short distance and has an immature appearance. When the fruit is ripe, its green shell will crack, revealing the nucleolus wrapped in a rough shell. The kernel is yellow and has many small holes, and the outer shell is hard wood. The almond fruit is flat oval, with a round end and a pointed end, covered with a thin brown skin. Nucleolus contains 20% protein and does not contain starch. After being ground and pressurized, the oil squeezed out is about half of its own weight. Almond oil is light yellow. Although it has no fragrance, it has the effect of softening the skin. In all parts of China except tropical regions such as Guangdong and Hainan, it is mainly distributed in Hebei, Liaoning, Northeast China, North...

AI Technical Summary

Problems solved by technology

[0003] Before the further processing of almonds, it is necessary to classify different quality grades according to the size of the almond particles. Usually, a screening device is used for screening. The screening effect of the existing almond screening device is not ideal, and the feeding process is prone to Excessive accumulation of almonds is not conducive to the rapid passage of almonds through the sieve holes of the sieve plate, and the screening efficiency is low, which cannot meet the current rapid screening requirements for almonds
