Description

Technical Field

[0001] This utility model relates to a device for collecting and sorting hazelnuts. Background Technology

[0002] Hazelnuts are the fruit of the hazel tree, belonging to the genus *Corylus* in the family Betulaceae. They resemble chestnuts in shape, with a hard outer shell and a plump, white, round kernel that is edible. Hazelnuts are also known as mountain chestnuts, pointed chestnuts, and jujubes, and are considered one of the "four major nuts" along with almonds, walnuts, and cashews, with the latter even earning the reputation of "King of Nuts." Hazelnut trees are characterized by their cold resistance, drought resistance, tolerance to poor soil, early fruiting, high yield, good economic benefits, and long lifespan, making them an important ecological economic forest species. As the fruit of the hazelnut tree, the growth cycle is generally one year, from spring budding to autumn maturity. Hazelnut kernels serve as a source of high-quality plant protein, rich in arginine, aspartic acid, and other eight essential amino acids. Hazelnut production in my country has shown a slow but steady growth trend in recent years.

[0003] Hazelnuts are harvested in autumn, and should be picked promptly after ripening to ensure quality. The harvested hazelnuts undergo screening to remove incomplete, insect-damaged, moldy kernels, and impurities such as branches and leaves, leaving only whole, clean hazelnuts. Vibrating screens are commonly used for screening, using vibration to move the hazelnuts on the screen. The screen's mesh size separates substandard hazelnuts and impurities, while qualified hazelnuts remain on the screen. For example, patent CN211587471U discloses a hazelnut screening device, which includes a screening shell. An inclined first vibrating screen is fixedly connected inside the screening shell, and an inclined second vibrating screen is fixedly connected below the first vibrating screen inside the screening shell. Two opposing inclined plates are fixedly connected to the bottom plate of the screening shell. A feed inlet is opened on the top plate of the screening shell, and a feed pipe is fixedly connected to the feed inlet. A feeding hopper is fixedly connected to the feed pipe. An insert plate is slidably connected to the feed pipe. This hazelnut screening device achieves the purpose of screening hazelnuts by setting up a first vibrating screen and a second vibrating screen. However, this type of vibrating screen is difficult to remove impurities such as branches and leaves mixed in, and the hazelnuts are irregularly shaped, resulting in a slow screening speed and low screening efficiency when using vibrating screens to screen hazelnuts. Utility Model Content

The sorting bins consist of a hopper (2) and a collection hopper (3). The hopper (2) is a horizontal cylinder with an opening at the bottom. The collection hopper (3) is located at the bottom of the hopper (2). The upper end of the ) is the feed inlet, which opens towards the bottom of the hopper (2); multiple sorting hoppers are connected end-to-end and connected by flanges (4); the feed end of the leftmost sorting hopper is equipped with a sealing plate, and the discharge end of the suction pipe (1) is set on the sealing plate of the leftmost sorting hopper, and the suction pipe (1) is connected to the sorting hopper; the left end of the second air pipe (6) is sleeved on the right end of the first air pipe (5), and the left end of the third air pipe (7) is sleeved on the second air pipe. (6) The right end of the third air pipe (7) is connected to the inlet of the impurity bin (8); the left end of the first air pipe (5) is provided with a connecting pipe, which is connected to the discharge end of the rightmost sorting bin; the first air pipe (5), the second air pipe (6) and the third air pipe (7) are all round pipes, the pipe walls of the round pipes are all cavities, the left end of the pipe wall of the round pipe is sealed, and multiple exhaust holes (12) are provided on the right end face of the pipe wall of the round pipe.

[0006] The principle and beneficial effects of this utility model are as follows:

[0007] In this utility model of hazelnut fruit collection and sorting device, the suction pipe (1) is used to collect hazelnuts. During the collection process, high-pressure air is introduced into the first air pipe (5), the second air pipe (6), and the third air pipe (7) by the first blower (9). The high-pressure air is discharged from multiple exhaust holes (12) set on the right end face, so that a high-speed airflow is generated in the suction pipe (1) and multiple sorting bins, which flows from the suction pipe (1) to the impurity bin (8). The feed end of the suction pipe (1) sucks in hazelnuts and enters multiple sorting bins. Hazelnuts of different weights have different landing points under the same airflow. Therefore, hazelnuts of different weights will fall into different collection hoppers (3) to achieve sorting. During the sorting process, the gas flow rate can be adjusted by adjusting the amount of high-pressure air introduced into the first air pipe (5), the second air pipe (6), and the third air pipe (7), so as to facilitate the adjustment of the sorting ratio for different fruits. Multiple sorting bins are arranged opposite each other at their ends and connected by flanges (4), so the number of sorting bins can be adjusted to adjust the number of sorting types. A second blower (13) introduces high-speed gas into the bottom of the sorting bins to further disperse and separate hazelnuts from impurities such as branches and leaves, improving the impurity removal effect. The impurities are finally collected in the impurity bin (8). This hazelnut fruit collection and sorting device can achieve efficient hazelnut fruit collection and sorting, and is flexible in assembly, adaptable, has a good impurity removal effect, and high screening efficiency.
