Abstract
The utility model relates to a suspension drawing rod flexible amplitude-modulated double-bladed plow, composed of a frame, a breast, a plowshoe, a ground wheel, a beam, an amplitude modulator, a suspender, and a suspension drawing rod device, wherein the suspension drawing rod device comprises an upper lead screw, a lower lead screw and an adjusting nut. The right and left screws at two ends of the adjusting nut are respectively connected with the right and left screws of the upper and lower lead screws, another end of the upper lead screw is movably connected with the suspender, and another end of the lower lead screw is fixed with the frame. When the frame translates, the suspension drawing rod rotates, and the length of the suspension drawing rod can be adjusted according to the translated distance of the frame, to hold the plow position, improve plowing quality and improve the service life of plow.
Description
The utility model relates to a kind of agricultural tillage machine tool---amplitude modulation double-bladed plough, especially a kind of amplitude modulation double-bladed plough that hangs the scalable adjustment of pull bar.
In the agricultural tillage machine tool, the amplitude modulation double-bladed plough is generally adopted at present.Patent Office of the People's Republic of China discloses a kind of " amplitude modulation double-bladed plough " in the CN2171977Y bulletin, be characterized in, when the operation of angle, border district, the ridge, can make frame along cross beam translation, can solve the problem that the common double turnplow is ploughed partially.But the shortcoming of this double-bladed plough is to hang pull bar to be connected on the frame, the other end and suspension gear flexibly connect, and during along cross beam translation, the end of fixing that hangs pull bar rotates along a movable end in frame, hanging pull bar is a fixed length, non-telescoping, so during the frame translation, the rear end must be lifted, make the depth in farming soil inhomogeneous, influence cultivating quality, and the plough body stressing conditions is worsened, reduce service life.
The purpose of this utility model is to provide a kind of suspension pull bar telescoping amplitude modulation double-bladed plough in order to overcome above-mentioned the deficiencies in the prior art part, and it can make frame translation position more accurate, improves cultivating quality, improves the service life of double-bladed plough.
The purpose of this utility model realizes by following measure: a kind of suspension pull bar telescoping amplitude modulation double-bladed plough, by support assembly, plough body assembly, mouldboard, plowshoe, wheel assembly, crossbeam and amplitude modulation mechanism, hitch and suspension drag link mechanism etc. form.Wherein hang drag link mechanism and comprise upper screw rod, following screw mandrel and setting nut; The upper end and the hitch of upper screw rod flexibly connect with pin, and the right-hand thread part of lower end partly is connected with the right-hand thread of setting nut upper end; The left-hand thread part of following screw mandrel upper end partly is connected with the left-hand thread of setting nut lower end, and the frame of following screw mandrel lower end and support assembly connects firmly.
The utility model compared with prior art has following advantage: the utility model is improved on the basis of existing amplitude modulation double-bladed plough, owing to adopted above-mentioned technology, make the suspension pull bar of original regular length become adjustable, length can be stretched, therefore when the frame translation, hang pull bar rotates thereupon, can regulate the length that hangs pull bar according to the size of frame translational movement, make the plough body upper-lower position constant, stressing conditions is constant, guarantee that the arable land depth is even, improve cultivating quality, improve the life-span of amplitude modulation double-bladed plough.
Below in conjunction with Figure of description the utility model is further described.
Fig. 1 is a front view of the present utility model.
Realize best way of the present utility model: with reference to Fig. 1, hang pull bar telescoping amplitude modulation double-bladed plough by support assembly 1, plough body assembly 2, mouldboard 3, plowshoe 4, wheel assembly 5, crossbeam and amplitude modulation mechanism 6, hitch 7 and hang drag link mechanism etc. and form; Wherein support assembly 1, plough body assembly 2, mouldboard 3, plowshoe 4, wheel assembly 5, crossbeam and amplitude modulation mechanism 6, hitch 7 etc. all identical with the amplitude modulation double-bladed plough; Keystone configuration characteristics of the present utility model are to hang drag link mechanism to be made up of upper screw rod 8, setting nut 9 and following screw mandrel 10, and upper screw rod 8 one ends are made hangers, and the other end is made the right-hand thread with certain-length; Endoporus one end of setting nut 9 is made the right-hand thread other end and is made left-hand thread; Following screw mandrel 10 1 ends are made the left-hand thread with certain-length, and the other end bores an aperture, and the nominal diameter of the negative thread of the threaded portion of screw mandrel and setting nut 9 is consistent about making.The hangers of upper screw rod 8 flexibly connects with hanging assembly 7 with pin, and threaded portion is connected with setting nut 9; Following screw mandrel 10 threaded portions are connected with setting nut 9, and the other end connects firmly by aperture and support assembly 1.
