Fruit and vegetable screening machine

Abstract

The invention discloses a fruit and vegetable screening machine. The fruit and vegetable screening machine comprises a supporting frame, wherein a guide plate is arranged above the supporting frame; the top of the guide plate is provided with a feeding box; front and rear ends of the guide plate upwards extend to form baffle plates; a plurality of guide baffle plates are arranged between the baffle plates; a guide channel is formed between every two guide baffle plates; ends, away from the feeding box, of the guide baffle plates are provided with screening devices; each screening device comprises a screening board, a screening box, and a plurality of screening slots which are formed in the screening plate, wherein screening holes of different sizes are formed in the screening slots, the screening holes are sequentially arranged to the bottom ends of the screening slots from big to small in a longitudinal direction of the screening slots, the bottom ends of the screening slots are provided with screening baffle plates, a plurality of transfer slots are formed in the screening box, each transfer slot corresponds to multiple screening holes of the same dimension, transfer tubes are arranged between the screening holes and the transfer slots, notches are formed in side walls of joints of the transfer tubes and the screening holes, and distance adjustable devices are inserted into the notches. The fruit and vegetable screening machine disclosed by the invention is convenient for relieving a blockage phenomenon while quantity of fruits and vegetables is great.

Description

technical field [0001] The invention relates to a screening device, in particular to a fruit and vegetable screening machine. Background technique [0002] After the current fruits and vegetables are mature, due to light, nutrition and other reasons, the sizes of fruits and vegetables are not the same, and the prices of fruits and vegetables of different sizes are also different, so they need to be screened, but the current screening mechanism usually pours the fruits and vegetables into the The material port enters the screening mechanism from the feed port. The existing screening mechanism is prone to blockage when there are a large number of fruits and vegetables, and it is relatively smooth when a small amount of fruits and vegetables are screened. Therefore, those skilled in the art provide a fruit and vegetable screening machine , to solve the problems raised in the background art above. [0003] The patent application with the publication number CN207521294U disclose...
