Description

Fruit vibration separation is equipped

Technical field

The present invention relates to fruit graded technical field, more particularly to a kind of fruit vibration point based on multi-stage oscillating screen net Grade equipment.

Background technology

Fruit and vegetable food has higher economic value added, can create better economic benefit, in recent years fruit and vegetable food Planting scale and total output are continuously improved, this just proposes higher to the harvest of fruit and vegetable food, classification, processing, package packing machine Requirement.

Fruits and vegetables classification refers to that fruit and vegetable food size, shape, color of field production etc. can not possibly be completely the same, by dividing Grade, is classified by quality, color and luster, size, maturity, cleannes and degree of injury, makes the standardization of product-quality indicators.Classification makes not at the same level Other product captures different market, reduces the wasting of resources.Fruits and vegetables after classification, quality, size are basically identical, and product is neat Beauty provides common trade language for each link of production, supply and sales, and the strange land transaction, information convenient for fruits and vegetables difference market of the same race are mutual Change, be the basis for realizing high quality and favourable price conducive to price fixing, fruits and vegetables classification conducive to auction, agency, contract, online etc. it is efficient, advise The formation and market specifications management of the modernization mode of doing business of model, the important symbol of modern management.

General fruit graded machinery can be divided into size classifier by operation principle, such as engineering technology institute of Hua Zhong Agriculture University The Grid Cylinder Dry Apricot Sorting Machine that three layers of drum-type gingko classier of development, traffic machine institute of Xinjiang Agricultural Univ develop Deng；Weight grader, such as YCM-002 type electronic type fruits and vegetables weight graders；Fruit colour grader, such as Mitsubishi electric appliance public affairs Take charge of the fruit maturity grader developed and the fruit colour weight grader such as U.S. " Inspecttronic " device.

The fruit size and shape that size classifier is selected are basically identical, are conducive to package storage and working process, therefore It is most widely used in fruit classifier, walnut is classified just in this way.The development comparative maturity of size classifier utilizes Different classification means, achieve the purpose that classification.Generally speaking, following several types can be divided into, we are introduced respectively：

Perforated tape and grid roller grader suitable for round fruits and vegetables, are classified according to its size.It is equipped with the broadband of sieve pore Generally it is made of fibre, canvas, rubber, metal or other materials.Conveyer belt can only have a kind of sieve pore of size, and incite somebody to action The small a product for falling into sieve pore that cannot be sold is removed or conveyer belt is divided into several stages, has small sieve pore in the first stage, after Each section gradually increases sieve pore, and the screening part of grid cylinder grader is made of 3 sections of rollers, the grizzly bar gap of every section of roller Difference, the 1st grade gradually increases to the gap of 3rd level grizzly bar, when fruit diameter is less than grizzly bar gap, just falls in contrast down In the receiving hopper answered.But due to classification when may make fruit by larger collision, impact and cause damage, so usually It is insensitive to mechanical load and to do the fruit grading being processed further therewith for those.

V shape grader, V shape grader are called belt or chain type classification machine, and classification position can be by two round conveyer belts (chain) or a conveyer belt (chain) and a rotary shaft pairing are formed.It is above-mentioned it is each pair of be not it is parallel but it is oblique fork form " eight " word Shape.Pairing position starts very close to the two distance regularly increases later, so smaller product rising at classification position Beginning just has fallen, and larger product may then be transported to and remotely fall.During sorting, two tape speeds can differ, and make Fruit generates certain rotation when interband conveys, thus is more suitable for sorting the aspherical fruit as pears.

Adjustment height grader and baffle-type grader, adjustment height grader and baffle-type grader are on the conveyor belt Portion is spaced apart to set a cross bar, and big in height of the starting end cross bar away from conveyer belt, rear side rod is gradually dropped away from conveyer belt height Low, when conveyer belt, which carries fruit, to march forward, big fruit wears only cross bar, is installed under the rotating circular disk effect on cross bar from defeated Band is sent to fall, smaller fruit passes through the first cross bar, but has part to wear only the second cross bar and fallen from conveyer belt, in this way production Product are divided into different brackets from big to small.Circular table center is micro- a protrusion, 2~3m of diameter, platform during rotating, Fruit is made always to roll to fixed annular plate washer while rotation with platform, plate washer lower edge is installed, and adjustable with respect to table inclination It is whole, it is different by gap so as to be formed, play the role of sorting.In order to help fruit easily by this gap, rotary work A certain number of hairbrush are also installed by gap location on platform.This sorting unit is suitble to the spherical for example many kinds of veterinary antibiotics Apple, tomato etc. is classified.

Hopper hole diameter expands grader automatically, and hopper hole diameter expands grader and is also referred to as membrane flap type grader automatically.Grader Variable hopper by conveyer belt connecting by rows.Hopper has multiple components to form, in the mistake that conveyer belt forwards Cheng Zhong, the component of hopper expand automatically, at leisure, and a piece flower of likeness in form is slowly opening, and the trepanning of classification hopper is made gradually to expand Greatly, the smaller material of size is first fallen from hopper, is fallen on conveyer belt is intersected, is transported to big wooden case.Conveyer belt with hopper continues Advance, hopper continues automatic expand, and first class product falls below intersect on conveyer belt.Since hopper is in transmit process hole itself Diameter constantly expands automatically, so as to be divided into several grades material is ascending.

Roller grader is bored, cone roller grader is made of pairs of tapered roller, there is gap therebetween.Fruit is located at two axis On gap, and advance with conveying device, when fruit diameter is less than roll shaft, drop into the fruit tray below roller.It is because flat Capable cone roller gap is gradually increasing, therefore fruit can be divided into different grades according to the variation in gap.

But existing size classifier is mostly bulky mechanical equipment, and equipment cost is high；Function is single, is only applicable to The fruit vegetable materials of several fixed shape sizes, Flexible Equipment are poor；Especially the grader of sieve or grid type is to stock grading When, can all effect of impact be generated to fruit, easily damage fruit, and during material falls, the posture of itself is random, makes It is not high into effectiveness of classification；Most of size separation machines can effectively realize classification by shape screening, but most machineries do not design Anti- overstocked blockage mechanism, odd fruit easily make equipment occur blocking interim card, affect the normal operation of the equipment.

Company in Chongqing devises walnut classified screening device, and inner cylinder and outer barrel, inner cylinder are equipped on supporting rack Internal portion is divided into first chamber, second chamber and third chamber by partition board with holes, and outer barrel is sleeved on the outside of inner cylinder, Chamber between inner cylinder and outer barrel is divided into 3 cavitys by corresponding partition board in outer inner barrel by two annular partitions, Corresponding first chamber, second chamber and third chamber set the first export of walnut, the second export of walnut respectively on each cavity With third export of walnut, walnut overfall, the diameter of walnut overfall are respectively provided on first chamber, second chamber and third chamber It is sequentially reduced, the center installation shaft of inner cylinder side, shaft is by belt connection mounted on the motor of supporting rack lower part The present invention realizes classification by the way that sorting screen drum is divided into different screening stages, time saving and energy saving, greatly improves work efficiency, subtracts The light labor intensity of worker improves the quality of screening.

But above device screens fruit by size shape, does not account for shape especially lopsided fruit and machine is made Into unexpected Caton phenomenon, not designing specific mechanism prevents the blocking of overfall.And each chamber overfall is single, if any The blocking of one outlet interim card can impact entire machine.

In summary factor is fully considered by team's many experiments and size classifier are technologic, is found existing Size classifier is difficult to meet simultaneously the precisely requirement such as classification and automatic anti-blocking, can not meet the needs of client and market, institute It to equip to solve problem encountered so that there is an urgent need to a kind of perfect fruit automatic classifications, fill up the blank in market, push outer Sell the great change of industry.
