Agricultural product screening and weighing system

Abstract

The invention discloses an agricultural product screening and weighing system which comprises a sorting device, an opening device, weighing-conveying belts, a packaging box conveying roller bed, a protective cover and a console, wherein the sorting device mainly comprises a screening body; the screening body is composed of lateral plates, a bottom tray and a screening plate which are supported bya bracket; through the vibrating action of vibrating motors fixed on two sides of the screening body, hazelnuts are subjected to three-stage impurity removal and classification by utilizing the natural slope of the screening plate and by adopting the vibrating screening principle; defective hazelnuts obtained from the classification and screening process are boxed and collected through a first discharging port; second-stage non-defective products are loaded into packaging boxes through a second-stage discharging port; through a lateral non-defective product weighing-conveying belt, the second-stage non-defective products are conveyed to a discharging roller bed for quantitative packaging after being weighed; finally-sorted high-quality hazelnuts reach the opening mechanism through an end-part discharging hopper and are opened under the squeezing action of a motor connecting rod; finally, the high-quality hazelnuts are loaded into the packaging boxes; and through a lateral high-qualityproduct weighing-conveying belt, the high-quality hazelnuts are conveyed to the discharging roller bed for quantitative packaging after being weighed. The integrated flow operation of impurity removal, screening, opening, weighing and packaging is achieved.

Description

technical field [0001] The invention relates to the field of agricultural product processing machinery, more specifically, it relates to an agricultural product screening and weighing system, which is also suitable for processing granular nuts such as walnuts and plantains by changing the sieve plate. Background technique [0002] Traditional hazelnuts are mainly sorted manually or by small machinery, the sorting is not standardized and the size is uneven. The opening method mainly adopts grinding, polishing, soaking with chemical solution, frying in high temperature oil to implement opening or adopting pure manual opening. Workers clamp the hazelnuts with opening pliers to make the opening, which is extremely inefficient. There are also small mechanical openings, but the crushing rate is too high due to uneven extrusion. Most of the packing adopts offline manual packing and weighing. Traditional processing methods are time-consuming, labor-intensive, inefficient, and the ...

AI Technical Summary

Problems solved by technology

Traditional processing methods are time-consuming, labor-intensive, inefficient, and the particle size is uneven, which easily damages the pulp and makes the overall quality of hazelnuts not high.
