Description
Technical field
The present invention designs a kind of plough, particularly a kind of straw-returning plough.
Background technology
At present, the plough plowed does not have straw-returning function mostly, if will, by straw-returning, also need to increase straw cutting apparatus more in addition before plowing.And now the maize straw large area in rural area also mostly adopts first to pulverize and plows afterwards or rotary tillage two links in field, also handlebar maize straw exempts to pulverize overall burying, no matter all there is a shortcoming in which kind of straw-returning method, very effectively stalk can not be buried completely exactly, after having ploughed ground, some stalk is exposed at earth's surface, and rotary tillage dew is more, thus cause having quite a few wheat seeds just to broadcast on this stalk during sowing, this just causes after planting, and germination rate is low, the amount of tillering is little, 5 ~ 10 jin are sowed more than every mu, and seedling is weak, winter easily freezes to death.In addition, although also there is now the straw cutting apparatus used together with ploughing and arranging in pairs or groups, it is still more shallow to the burying depth of stalk, still has some stalks and is exposed at earth's surface.Be more than the deficiencies in the prior art.
Summary of the invention
The object of the invention is: design a kind of straw-returning plough, this straw-returning plough can realize straw-returning while arable land, no matter be plow straw-returning after first crushing straw, still exempting to pulverize directly to plow buries and field by stalk entirety, stalk can both be buried completely, and dark to the burying depth of stalk, stalk can not be exposed at earth's surface, in order to overcome the deficiencies in the prior art.
Object of the present invention can be realized by following technical proposals:
A kind of straw-returning plough, comprise plough, described plough is provided with the universal joint that one end is connected with tractor output shaft, be arranged on the gear-box speed changer on plough front-axle beam, be arranged on the jackshaft on plough crossbeam, be arranged on the some wheel shafts before each ploughshare and some saw break bars with point of a knife, the other end of described universal joint is connected with the input axle of gear-box speed changer, the output axle of gear-box speed changer is connected with jackshaft by sheave and belt, described some saw break bars are arranged on described some wheel shafts respectively, described some wheel shafts are all connected with jackshaft by sheave and belt, it is characterized in that: also comprise hydraulic pump, some hydraulic motors, some stalk platens, high-pressure oil pipe, high-pressure series oil pipe and oil return pipe, hydraulic pump is arranged on after jackshaft, the power shaft of hydraulic pump is connected with jackshaft by sheave and belt, before some hydraulic motors are separately positioned on each ploughshare, several being connected with plough crossbeam can be gone up, on the lower elastic support floated, the below of each elastic support is provided with each stalk platen be connected with the output shaft of each hydraulic motor, each stalk platen is positioned at the outside of each saw cutter, high-pressure oil pipe one end is connected with the oil-feed port of hydraulic pump, the other end connects the oil-in of one of them hydraulic motor, all be connected by high-pressure series oil pipe respectively between some hydraulic motors, the oil-out of last hydraulic motor is connected with one end of oil return pipe, the oil return opening of the other end connecting fluid press pump of oil return pipe.
The each elastic support of the present invention is by auricular branch seat, ring seat, adjustable shelf, bearing pin, spring and movable post composition, auricular branch seat is before each ploughshare, be fixedly connected with plough crossbeam, the right flank upper position of auricular branch seat is welded with ring seat, adjustable shelf is flexibly connected with auricular branch seat by bearing pin, the upper end of spring is connected with ring seat, movable post is installed in spring and ring seat, the lower end of movable post is connected with the erection column be positioned on the right side of adjustable shelf, the upper end of movable post is stretched out by ring seat, each hydraulic motor is fixed on adjustable shelf, the each stalk platen be connected with the output shaft of each hydraulic motor is provided with in the below of adjustable shelf.
The point of a knife that the present invention saws on break bar is integral type structure with saw break bar body, or is split-type structural; When sawing the point of a knife on break bar and being Split type structure with saw break bar body, point of a knife is the self-mountable & dismountuble point of a knife it being welded with alloy, and point of a knife is arranged on the outer circumference surface of saw break bar body.
Advantage of the present invention is: 1) this straw-returning plow structure is simple, easy to use, straw-returning can be realized while arable land, straw-returning power foot, no matter be plow straw-returning after first crushing straw, still exempt from that pulverizing directly plows to bury also field by stalk entirety, stalk can both be buried completely, and dark to the burying depth of stalk, stalk can not be exposed at earth's surface; 2) use this straw-returning ploughing soil will and by after straw-returning, because the burying depth of stalk is dark, during sowing, wheat seeds would not be broadcast on the stalk in also field, therefore more save wheat seeds, after planting germination rate is high, the amount of tillering large, Miao Zhuan.
