Abstract
The invention discloses a litchi sieving and grading machine and a litchi sieving and grading method. The litchi sieving and grading machine consists of a fence type fruit discharging slot, a mesh-belt conveyor, a cull fruit conveyor and at least two size grading machines, wherein grids for filtering small foreign matters are arranged in the fence type fruit discharging slot; a spreading device and a sprinkling and cleaning device are arranged in the mesh-belt conveyor; rotten fruit throwing holes are arranged at both sides of the mesh-belt conveyor and led to the cull fruit conveyor; each group of size grading machine is provided with a flowing sieve which consists of two groups of chains and chain guide racks, a friction rack and a supporting roller; and the supporting roller space of the first group of size grading machine is smaller than that of the second group of size grading machine. The invention has simple structure, easy production and manufacture and convenient use and operation and is used for sieving and grading litchi with high precision and the lowered labor strength; and the sizes of the sieved litchi of the same grade are uniform, thus market demands are satisfied.
Description
Technical field
The present invention relates to a kind ofly be used for the equipment of lichee size fractionation and utilize this equipment to carry out the method for litchi sieving and grading, belong to fruit processing equipment technical field.
Background technology
Existing lichee size classification mainly relies on artificial selection, not only the working time long, labour intensity is big, and can't guarantee the lichee consistent size that same ranking score is selected, thereby influences sharpness of separation.Though existing fruit grader is a lot, for example, fruit graders such as apple, oranges and tangerines are not because the excesssive gap between the carrying roller is suitable for the lichee classification.Along with social progress, people's standard of living improves constantly, and people strengthen the selectivity of food fruit, and the lichee size of selling on the market mixes, and can not satisfy people's demand.
Summary of the invention
Purpose of the present invention is exactly for satisfying the needs in market, uses for reference existing fruit grader on the market, is studied improvement, a kind of litchi sieving and grading machine is provided and utilizes the method for this litchi sieving and grading machine sieving and grading.
First purpose of purpose of the present invention is achieved in that litchi sieving and grading machine, form by mesh-belt conveying section and size classification section, the mesh-belt conveying section is provided with fence type and unloads fruit groove, wired belt conveyer, cull fruit conveyer, fence type unloads in the fruit groove and is provided with the grid that filters little foreign material, be provided with lying device and spraying and cleaning apparatus in the wired belt conveyer, the wired belt conveyer both sides are provided with decayed fruit and throw in the hole, and the cull fruit conveyer is led in decayed fruit input hole; Two packet size graders before and after size classification section is provided with at least, every packet size grader is provided with the overcurrent sieve that two groups of chains and chain sliver, fricting strip, carrying roller constitute, and the carrying roller gap of the overcurrent sieve of preceding packet size grader is less than the carrying roller gap of the overcurrent sieve of back packet size grader.
The technical scheme that second purpose of the present invention realizes is:
(1) adopts litchi sieving and grading machine, will put in order the frame lichee earlier and pour fence type into and unload the fruit groove, unload by fence type that little foreign material of grid filtering part in the fruit groove are laggard goes into the guipure conveyer;
(2) lying device of wired belt conveyer and spraying and cleaning apparatus pave the lichee of piling up smooth and clean, the decayed fruit of decayed fruit by the wired belt conveyer both sides thrown in the hole and enters the cull fruit conveyer and deliver to assigned address, and remaining lichee then enters the size classifier of size classification section;
(3) parallel two groups of synchronous chains move along chain sliver drive carrying roller in the size classifier, the bearing pin that carrying roller stretches out around chain under the fricting strip effect rotates, under the acting in conjunction of synchronization chain and fricting strip, make carrying roller move forward on one side, carry out the constant rotation of spacing on one side, rotate thereby drive lichee, make size from adjacent trustship gap, leak down less than the lichee of idlers pitch;
(4) lichee is through at least two packet size grader classifications, is provided with gathering-device below every packet size grader, forms the grade lichee that the lichee diameter is arranged from small to large, and each grade lichee that classification is come out collects.
Litchi sieving and grading machine provided by the invention, simple in structure, manufacture easily, utilize this litchi sieving and grading machine to carry out litchi sieving and grading, use easy to operate, sieving and grading precision height, improve sieving and grading efficient, reduce labour intensity, the lichee consistent size of the same grade that sub-elects is met the need of market.
The design fence type unloads the fruit groove, can effectively leak except that foreign material such as silt and leaves.Wired belt conveyer cleans pave even water of lichee, is convenient to manually choose inferior fruit, with the concentrated appointed place that outputs to of the cull fruit of artificial sort out.The overcurrent sieve of litchi sieving and grading machine can make adjacent two idlers pitches keep basic weighing apparatus fixed by adjusting the distance between the carrying roller, thereby guarantees the lichee size basically identical of same grade sorting.The sorting of installing machines to replace manual labor guarantees the lichee equal and opposite in direction that same ranking score is selected.And can carry out the size classification by customer requirements, make the lichee of each grade have identical outward appearance and quality; Its spray Cleaning for High Capacity part washes dust, residues of pesticides and other external dirts on lichee surface, and increases the fresh keeping time of lichee.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is an overcurrent sieve structure schematic diagram of the present invention;
Fig. 3 is the idler assembly structural representation of overcurrent sieve of the present invention;
Among the figure: 1 fence type unloads fruit groove, 2 wired belt conveyers, 3 cull fruit conveyers, 4 one packet size graders, 5 two packet size graders, 6 three packet size graders, 7 chains, 8 chain slivers, 9 fricting strips, 10 carrying rollers.
The specific embodiment
Litchi sieving and grading machine is made up of mesh-belt conveying section and size classification section, and the mesh-belt conveying section is connected with size classification section.The mesh-belt conveying section is provided with fence type and unloads fruit groove 1, wired belt conveyer 2, cull fruit conveyer 3, fence type unloads fruit groove 1 and connects wired belt conveyer 2, cull fruit conveyer 3 be arranged on wired belt conveyer 2 below, fence type unloads in the fruit groove 1 and is provided with the grid that filters little foreign material, be provided with lying device and spraying and cleaning apparatus in the wired belt conveyer 2, wired belt conveyer 2 both sides are provided with decayed fruit and throw in the hole, and cull fruit conveyer 3 is led in decayed fruit input hole.Size classification section is provided with 4,5,6 three packet size graders, also can be arranged to two groups or four groups, five packet size graders etc.One packet size grader, the 4 anterior wired belt conveyers 2 that connect, the rear portion connects two packet size graders, 5, two packet size graders, 5 rear portions and connects three packet size graders 6.Every packet size grader constitutes the overcurrent sieve by two groups of chains 7 and chain sliver 8, fricting strip 9, carrying roller 10, and the carrying roller gap of the overcurrent sieve of preceding packet size grader is less than the carrying roller gap of the overcurrent sieve of back packet size grader.The bottom of every packet size grader is provided with gathering-device.
