Multi-stage screening device for red kiwifruit classification

Abstract

The invention belongs to the technical field of screening, and particularly relates to a multi-stage screening device for red kiwifruit classification. The multi-stage screening device comprises a screening seat, a supporting seat is fixedly connected to the lower surface of the screening seat, a hollow pipeline is fixedly connected to the interior of the screening seat, and a first bevel gear isrotatably connected to the interior of the supporting seat; and second bevel gears are engaged with the left side and the right side of the first bevel gear correspondingly, threaded columns are rotatably connected to the side surfaces of the second bevel gears, rotating gears are engaged with the outer surfaces of the threaded columns, stretching rods are rotatably connected to the outer surfacesof the rotating gears, and a compression shaft is movably connected to the interior of the hollow pipeline. When the multi-stage screening device is used, the angle between V-shaped frames is regularly increased or decreased, meanwhile, the V-shaped frames drive screening nets to be in a contracted or unfolded state, and therefore at the moment, kiwi fruits on the surfaces of the screening nets can be screened to a certain degree; and the multiple screening nets with different hole diameters are arranged, so that multi-stage screening can be achieved.

Description

technical field [0001] The invention belongs to the technical field of screening, and in particular relates to a multistage screening device for sorting kiwifruit with red hearts. Background technique [0002] Kiwi fruit, also known as kiwi fruit, is generally oval in shape; the early appearance is green-brown, and it becomes reddish-brown when mature; the skin is covered with thick fluff, and the inside is bright green pulp and a row of black or red seeds; the texture is soft, The taste is sweet and sour. In addition to organic substances such as actinine, proteolytic enzymes, tannin pectin and sugars, as well as trace elements such as calcium, potassium, selenium, zinc, germanium and 17 kinds of amino acids needed by the human body, it is also rich in vitamins C. Glucoic acid, fructose, citric acid, malic acid, and fat are very popular among people. Before kiwi fruit is classified, it is often necessary to sieve it. [0003] At present, when kiwi fruit is screened, the st...

Problems solved by technology

[0003] At present, when kiwi fruit is screened, the staff usually screens it by themselves, the workload is large, and time is wasted. Although some screening devices are used for screening, the screening effect is not good, and it is difficult to achieve as many Level screening will affect the subsequent classification and packaging of kiwifruit, and the operation is more cumbersome. Therefore, in view of this, we will study and improve the existing structure and lack, and provide a multi-level screening device for the classification of kiwifruit with red hearts. To achieve a more practical purpose
