Description

Vegetable winnowing equipment

Technical Field

The invention belongs to the technical field of vegetable winnowing, and particularly relates to vegetable winnowing equipment.

Background

The winnowing machine is used for separating light materials and heavy materials through blowing, is widely applied to winnowing operation of various fruits and vegetables, separates fruit bodies from miscellaneous leaves, and greatly saves the production time of enterprises due to the application of the winnowing machine.

The Chinese patent number is: (CN 202211468305.6) discloses a self-circulation air separator of dehydrated vegetables, relates to vegetable processing technical field, includes: the air separation device comprises a fixing frame, wherein an induced draft fan is arranged on the fixing frame, a mounting frame is arranged on the left side of an air separation bin and is matched with the elastic action of a first compression spring, a sliding block drives a vibrating screen to float up and down in the air separation bin, fruit bodies and miscellaneous leaves cannot be sufficiently dispersed, so that the separation efficiency is lower, the screen structure of a recovery box and a discharge opening is simple, a large amount of materials are easily deposited on the surface of the screen, and the screening efficiency can be reduced.

The above scheme still has the following disadvantages in the implementation process:

1. above-mentioned scheme only vibrates the material through vibrating screen in the implementation process to can not make the material dispersion more abundant, when disposable throw-in material is too much, the dispersion effect is limited, is difficult for discharging impurity when taking place to pile up easily, has reduced selection by winnowing efficiency.

2. According to the scheme, the mixed leaves and the materials are separated through blowing of the induced draft fan, but the air outlet area is fixed and cannot be quickly adjusted, when different vegetable varieties are met, the wind force of the fan can be adjusted, the flexibility of the equipment is reduced, and the use requirement cannot be met.

3. When using vibrating screen, the air separator wholly also can vibrate thereupon, and above-mentioned scheme lacks the protection, and the whole collision of structure can greatly reduced life, and vibrating screen is fixed in addition and is difficult to dismantle, inconvenient later maintenance and cleanness.

Accordingly, in view of the above, research and improvement are made on the existing structure and the existing defects, and a vegetable winnowing device is provided, so that the purpose of higher practical value is achieved.
