Description

TECHNICAL FIELD

[0001] The utility model relates to fruit and vegetable screening blowing mechanism technical field, specifically is a fruit and vegetable screening double blowing mechanism. BACKGROUND

[0002] Air blowing screening, also known as air flow screening, is a technology that uses air flow as a screening medium to separate fruits and vegetables. Its working principle is mainly based on the power and direction control of air flow. During the screening process, fruits and vegetables are sent into the screening chamber and are screened by the action of air flow. Specifically, air flow blows up fruits and vegetables, making fruit and vegetable particles suspended and dispersed in the air flow. Because of the differences in size, weight and shape of fruits and vegetables, their movement trajectories in the air flow will also be different. Therefore, by adjusting the air flow parameters, fruits and vegetables of different sizes can be separated, achieving the purpose of screening and grading. The above-mentioned screening equipment is commonly used in fruit and vegetable screening.

[0003] The existing fruit and vegetable conveying machine generally uses a single blowing form, which is usually divided into up blowing or side blowing. Single blowing only installs a blowing device at the condition selection channel or the result channel. When the fruit and vegetable runs to this position, the blowing device acts. However, when the shape of the fruit and vegetable is irregular and there is a difference, if only one blowing mechanism is set, there may be a situation of missed blowing or blowing out of place, which affects the screening of fruits and vegetables.
