Background technology
The widely used multishare plough of China mainly contains Two-furrow plough three turnplow four-furrow ploughs at present ...
(1) the colter frame adopts square tube to be welded into the whole flat frame of front and back colter, and the colter support adopts the ironcasting manufacturing, and after the fine finishining, four screws are fixed on flat frame square tube, stressed back pipe deformation, and screw is loosening, ploughs under the point and plants, the very effort of ploughing, even draw motionless.
(2) adopt single-wheel, be fixed on the back colter, in the middle of the flat frame, the stressed back of wheel is parallel with towing plate, at uneven soil cultivating, to cradle, back colter has at present plants, and draws motionless going up sometimes to jump, and formation is balked, preceding colter, do not have wheel control, plant under the colter, pull-up is required great effort very much, even draws motionless.
(3) because the tractor that each factory produces is just different, the tractor height difference of 12-20 model, differ the 60-100 millimeter, the width difference differs the 20-60 millimeter, complete on the tractor, the shadoof screw is adjusted up and down, and width by adjusting before and after an extension pin on the colter frame, is adjusted entirely like this, all be tiltedly to plough plough, pull-up is required great effort very much, and 12 model tractors draw motionless, all uses the farming of 15-20 model tractor.
(4) colter support and wheel bone all are to adopt ironcasting, and casting and fine finishining want plurality of devices just can finish, and take a lot of work, cost height, quality be bad again.
(5) can not completely plough (merchant raises) plot both sides has 30-40 centimetre soil not turn over, and must use hand steered Dan Li, just can carry out additional cultivation, and each farming need two people be operated, and is with two plough, a hand steered Dan Li, a double-bladed plough.
(6) tractor-drawn is tiltedly ploughed ploughing and is done, on one side wheel walk in the ditch, askew to the right, the colter frame is also askew to the right, because frame and integral body of extension pin weldering, at uneven soil cultivating, can not swing up and down, the plough degree of depth is 180 millimeters before causing during farming, back plough degree of depth 120-150 millimeter, adjusted, greedy ripe, not well done, the arable land is the same to a snake, does not form straight line operator on the tractor's farming, before and after looking after, the time this gets off to adjust plow frame, entirely by two shadoofs on the tractor, upwards carry for one, one to pressing down and the movable pin adjustment front and back that hang, if adjust bad, plant under the preceding plough point, the back plough is sharp not to be gone down, and formation is balked, draw motionlessly, adjust very inconvenient.
(7) the old foreign Two-furrow plough of import
1, a chain articulates the tractor back, and tractor is to plow frame, and control ability is very weak, needs two people operation, and a people sets frame in the back, could farming.
2, two-wheel adjustment, front-wheel control is very weak, can not fall soil block in the ditch, if soil block is arranged, jumps on the front-wheel, goes back and forth between two places, and cultivated ditch is not straight, resembles a snake, preceding colter degree of depth 120-150 millimeter, 180 millimeters of the back colter degree of depth, it is greedy ripe to plough.
3, can not be completely cultivated, need hand steered Dan Li, hang over the tractor back with chain, just can carry out additional cultivation.
4, trailing wheel handle spring pin improves the trailing wheel height, stressed after, upwards jump, formation is balked, it is very inconvenient to plough.The soil of China is very complicated, and sandy soil ground is ploughed easily, its afterimage magma ground, blackland, clay ground is all harder, adds that per season ploughs all to go up chemical fertilizer, soil more than 200 millimeters, all chemical fertilizer soil is hard year by year, the soil is very not stiff when raining, and all now turnplow plough points are ploughed not go down, draw motionless, must drought resisting could farming, use 15-20 model tractor, the ability stretchy, the peasant is generally reflected the difficulty of ploughing.
