A kind of Green Chinese onion harvester
Technical field
The utility model relates to a kind of Green Chinese onion harvester, belongs to the Modern Agricultural Machine technical field.
Background technology
Through long market survey: the shallot cultivated area in Jinan every year is more than 200,000 mu; From the whole nation, shallot is as a kind of Important Economic crop, and its cultivated area is considerable especially; Because the biological nature of shallot, and planting habit, always take artificial results as main, labour intensity is very large, and artificial labour cost has compressed the profit margin at plantation family greatly.Agricultural mechanization is the dominant direction of current agricultural production, because mechanized harvest generally has higher efficiency of crop, and can very large reducing labor intensity.
Just present, mainly contain following two kinds of Green Chinese onion harvesters on the market: a kind of is towed Green Chinese onion harvester take tractor as supporting power, and another kind is the self-propelled Green Chinese onion harvester of self-powered platform.Towed Green Chinese onion harvester mainly contains vibrations plough formula and two kinds of full-automatic Green Chinese onion harvesters, and vibrations plough formula Green Chinese onion harvester mainly adopts the vibrations plow structure, and shallot root envelope soil is become flexible, and realizes the purpose of shallot results; Full-automatic towed Green Chinese onion harvester mainly comprises frame, propelling sheave, drive the soil plough, etc. parts, be intended to realize shallot results entire mechanization, but manufacturing cost is high, not strong without depth adjustment, versatility.Self-propelled Green Chinese onion harvester home products then has inconvenient operation, the shortcoming that manufacturing cost is higher; Although external product is functional, price is too high, also the small-scale cropping pattern of inapplicable and Chinese shallot.
In a word, domestic Green Chinese onion harvester ripe product without comparison also; The same kind of products at abroad price is too high, not too adapts to the domestic market.
Summary of the invention
The needs of producing for satisfying shallot plantation family, the purpose of this utility model is to overcome above-mentioned deficiency and a kind of Green Chinese onion harvester is provided, be the towed Green Chinese onion harvester of trifilar suspension, simple and compact for structure, labor aptitude is strong, flexible operation safety, high efficiency, stable and reliable for performance, the complete machine cost performance is higher.
The technical scheme that the utility model is taked is:
A kind of Green Chinese onion harvester, comprise supporting leg, supporting leg is provided with frame, be fixed wtih the driving gearbox on the frame, the power shaft that drives gearbox links to each other with the power output structure of tractor, and the output shaft that drives gearbox is connected with the plough main shaft, plough is the wheel knife structure with cutter, establish the arc guard shield above the plough, the rear side of plough is provided with rear cutter, and the rear end of frame is provided with gauge wheel.
Described supporting leg has three.Described driving gearbox adopts two stage speed change, drives gearbox and is fixed on the frame, and the gearbox biasing is realized on the right side of the position deflection tractor center line of frame and driving gearbox.
Described plough links to each other with the output shaft that drives gearbox, can realize endwisely slipping at axle; Rear cutter is connected with frame by the back tool rest pipe, and back tool rest pipe and frame are flexibly connected, and can laterally slide.
Described gauge wheel is fixed on frame rear end, fixes by bearing pin and frame, and a plurality of pin-and-holes are arranged on the gauge wheel, can regulate by vertical direction, plays the effect of regulating working depth.
The utility model moves ahead as supporting power traction frame with tractor, and power output drives the plough rotation as driving power behind the PTO, one side of close tractor is opened and is got groove on the shallot ridge, rear cutter gos deep into channel bottom, on large verdant bottom cutting lifting green onion ridge, plays the purpose of shallot results.
The utility model compared with prior art has following characteristics:
1. employing three-point suspension-type, the above tractor of available 65HP is as supporting power, and the product highly versatile operates more convenient;
2. drive gearbox and adopt two stage speed change, gearbox bias scheme, improve stationarity and the transmission efficiency of transmission, product structure is compact;
3. plough and rear cutter adopt horizontal adjustable scheme, improve Green Chinese onion harvester to the applicability in different plot;
4. increase gauge wheel has strengthened the adjustability of Green Chinese onion harvester, more is applicable to the results of the shallot of different growing ways.
The utility model has reduced the labour intensity of shallot results, has improved the operating efficiency that shallot is gathered in the crops, has reduced labour cost.

Embodiment
Further specify below in conjunction with embodiment.
A kind of Green Chinese onion harvester, comprise supporting leg 5, supporting leg 5 is provided with frame 6, be fixed wtih on the frame 6 and drive gearbox 7, the power shaft that drives gearbox 7 links to each other with the power output structure of tractor, and output shaft is connected with plough 2 main shafts, plough 2 is the wheel knife structure with cutter, establish arc guard shield 1 above the plough 2, the rear side of plough 2 is provided with rear cutter 3, and the rear end of frame 6 is provided with gauge wheel 4.
Described supporting leg 5 has three.Described driving gearbox 7 adopts two stage speed change, drives gearbox 7 and is fixed on the frame, and frame and driving gearbox 7 are realized the gearbox biasing on the right side of tractor center line.
Described plough 2 links to each other with output shaft of gear-box, can realize endwisely slipping at axle; Rear cutter 3 is connected with frame 6 by the back tool rest pipe, and back tool rest pipe and frame are flexibly connected, and can laterally slide.
Described gauge wheel 4 is fixed on frame 6 rear ends, and is fixing by bearing pin and frame 6, and a plurality of pin-and-holes are arranged on the gauge wheel 4, can regulate by vertical direction, plays the effect of regulating working depth.
Its operation principle is: move ahead as supporting power traction frame 6 with tractor, power output is as driving power behind the tractor PTO, drive gearbox 7 by gimbal coupling, drive plough 2 turn clockwise (observing from the tractor left side) by main shaft, one side of close tractor is opened and is got dark 600mm on the shallot ridge, the groove of wide 90mm, plough dish out earth be directed on the frame plough 2 and drive gearbox 7 by guard shield 1 in the middle of the neutral gear places fall on the ground, rear cutter 3 gos deep into channel bottom, on cutting lifting green onion ridge, bottom, shallot ridge, play the purpose of shallot results, gauge wheel 4 can be gathered in the crops for the shallot of different growing ways the adjustment of the degree of depth; Reaping machine puts down supporting leg 5 supports and deposits when idle.
