Description

The fresh and dried fruit grader

Technical field

The utility model relates to a kind of fresh and dried fruit grader, especially relates to a kind of grader that is applied to fresh and dried fruit, belongs to agricultural machinery technological field.

Background technology

Existing fresh and dried fruit stage division has several like this: (1) Gate bar drum-type; (2) vibratory sieve formula; (3) electromechanical integration formula classification; (4) artificial staging.First method, application is wider comparatively speaking, but the classification inaccuracy; Second method because the fresh and dried fruit volume is bigger, easily results in blockage bad control in practical operation; The third precision of method height, but cost height; The 4th kind of required labour of method is many, and labour intensity is big, and efficient is low.

The domestic fresh and dried fruit grading plant of having researched and developed has: (1) grid formula cylinder grading plant, this device is made up of the grizzly bar with certain taper, the rotation of cylinder drives dry fruit ceaselessly rises, falls, and moves forward under the driving of gravity and centrifugal force, until deviating from from roll letter; (2) awl roll-type grading plant.Awl roll-type grading plant adopts a pair of tapered roller in relative rotation, and dry fruit ceaselessly rises under the drive of two tapered rollers and falls, and simultaneously, dry fruit moves down at gravity and the upper end dry fruit acting in conjunction lower edge tapered roller to its lateral compression power.During greater than the diameter of dry fruit, dry fruit falls by the gap until the gap of two tapered rollers.(3) semi-automatic grading plant.Based on mechanical device, utilize detection control apparatus, carry out the automatic classification of mechanization.Through the Searches of Patent Literature, existing dry fruit grader, as Chinese patent: 200420002579.5, adopt cylindrical bar shaped sieve cage according to ascending being linked in sequence of grating interbody spacer size, dry fruit is in addition classification when sieving cage; 200420043157.4 adopt the housing of cylinder sieve nest and pack roller sieve nest, dry fruit carries out classification by sieve nest; 200420084433.1 employing when the bar shaped that the dry fruit of different sizes does not wait through each spacings is sieved, is carried out classification by the drum-type grader of two frameworks and number rod member institute structure.03273524.3 by thereon leading portion arrangement collating unit of belt conveyor and dress, detect belt conveyor, Photoelectric Detection sensing device and be that the automatic selecting device of jet thrust of power is formed with compressed air, by detecting feedback control signal, with the jet sorting of jet thrust.

Because the fresh and dried fruit kind is numerous and diverse, size difference is bigger, and shape is very irregular, simultaneously owing to the dry fruit particle reaches reasons such as fresh fruit cracky greatly than other solids thing classes, makes fresh and dried fruit be difficult to accurately classification by size.

Summary of the invention

At the deficiencies in the prior art part, the utility model provide a kind of simple in structure, classification efficiency is high, easy to operate, can realize fresh and dried fruit is carried out the device of the accurate classification of mechanization.

The utility model is for reaching above purpose, be to realize: a kind of novel fresh and dried fruit grader is provided, comprises frame, feeding hopper, feeding conveyer belt, receiving hopper, cutting plate, cutting plate bracing frame, protective cover, driven classification roller, main transmission classification roller by following technical scheme.Conveyer belt is positioned at the below of feeding hopper, and the cutting plate bracing frame is installed on the frame, and cutting plate on the cutting plate bracing frame, passes the classification roller by bolted on connection during Bolt Connection.

A kind of design as fresh and dried fruit grader of the present utility model: described cutting plate is the prismatic cylinder by 5-10 group profile, equidistantly arranges along the cutting plate bracing frame, forms up big and down small trapezoid space.

A kind of design as fresh and dried fruit grader of the present utility model: described cutting plate is parallel with the classification roller axis, is positioned at the grading roller top, on the material importing classification roller to be fractionated with conveyer belt output.

A kind of design as fresh and dried fruit grader of the present utility model: described grading roller tilts to place, and two adjacent classification rollers are done reverse outward turning and rotated, and classification roller spacing is ascending.

A kind of design as fresh and dried fruit grader of the present utility model: described when fresh fruit is carried out classification, should the discharging conveyer belt be installed at the case lower ending opening that connects material.

Fresh and dried fruit grader of the present utility model, except power section that common mechanical possessed, running part, feeding part, the core of invention is: the utility model adopts the stepless accurate classification of major axis formula, and guiding mechanisms such as bracing frame and cutting plate are the servicing units of fresh and dried fruit grader.The utility model has changed many drawbacks that hierarchical approaches is in the past brought, as: effectiveness of classification is not high, and versatility is not strong etc., has realized the mechanization of nut classifications such as fresh and dried fruit.Fresh and dried fruit grader of the present utility model, frame for movement is simple, and whole cost is low, and high efficiency is easy to operate, saves manpower and time, and guarantees the classification rate of fresh and dried fruit.
