Abstract

The utility model relates to an agriculture cultivation mechanical device, particularly an agricultural double-row four-share plow. The utility model is provided with four plow beams. Front plow legs and back plow legs are all arranged in front of and at the back of the plow beams. The back plow legs are longer than the front plow legs. A plowshare and a plow sole are arranged at the bottom of each plough leg. The plowshares are provided with the same specifications. The intervals of the plowshares can be adjusted. For cultivation, the soil penetrating depth of the plowshares of a front row is shallow; the soil penetrating depth of the plowshares of a back row is deep. Thus, cultivated ridges are smooth. The utility model has the advantages of good effect of soil crushing, convenient sowing, and convenient crop growth.

Description

Agricultural double-row four-shared plough

The utility model relates to a kind of agricultural primary tillage equipment device.

At present, carried out mechanized farming in some areas, China rural area, resembled and use dilatory tractor-ploughing to plow to popularize gradually, can not regulate but the shortcoming of this plough is its ploughshare spacing, the field that can not adapt to the different row spacings of farming, and this plough tool is single, and when farming, it is big to rout up the soil block that comes, can not fine hack, become the ridge out-of-flatness, the soil property poor air-tightness influences the quality of emerging.

The deficiency that the utility model purpose is done at single cultivated ploughing proposes a kind of double four-furrow plough, the adjustable primary tillage equipment device of ploughshare spacing, and it can improve farmland quality, increases machinery and ploughs the plough job area.

The utility model is double four-furrow plough, and front-seat ploughshare buries shallowly when ploughing, and back row's ploughshare buries deeply, and the ridge of ploughing out like this is smooth, and hack is effective, is convenient to sow, and helps crop growth.

Elaborate the utility model principle and structure below in conjunction with Fig. 1, Fig. 2: small frame 19 is supported on the big frame 20 by bearing 1,25,33,34 in the utility model, by axis hole 4 jack back 17 is installed on big frame 20 both sides, jack back 17 two ends are fixed with

gear

15 and 26 respectively,

gear

15,26 is meshed with the teeth groove on the small frame 5, teeth groove 5 is on two edges, small frame 19 front and back, with small frame 19 is one, when rocking-turn jack back 17, can make small frame 19 move left and right on big frame 20.On small frame 19, middle plow beam 27 is welded on small frame 19 middle parts, and both sides plow beam the 29, the 14th is supported on the small frame 19 by bearing 2,30 and 31,33 respectively, both sides plow beam 29 with 14 can relative in the middle of plow beam 27 is equidistant moves to centre or both sides, respectively be welded with a leading screw 3 on the both

sides plow beam

29,14, their same fiber tubes 6 of cranking arm connect.The fiber tube 6 of cranking arm is fixed on the middle plow beam hole 18; it can not move left and right; but can in middle plow beam hole 18, rotate; left and right sides plow beam 14 can stretch when it rotates; 29 draw close or separate to middle plow beam is equidistant; right-hand member at big frame 20 is equipped with the plow beam that can upwards mention 28 by hinge 8; in plow beam 28 front portions one hinge 9 is housed; an axis hole 12 is arranged on plow beam 28 rear portions; on big frame 20 right-hand member axis holes 10, fix a shadoof 11; the shadoof other end passes axis hole 12, and when mentioning shadoof 11, can make plow beam 28 serves as that axle is raised with hinge 8 and hinge 9; do not recur arable land effect allows three remaining plow beam work.Plow standard 21 and back plow standard 22 before before and after each plow beam, all having, back plow standard 22 is than preceding plow standard 21 length, be equipped with at the bottom of the plough of ploughshare 13 and parallel plow beam 16 in the plow standard bottom, each ploughshare all is same specification, the draw ring 7 and the draw ring 24 that connect with tractor be housed on the big frame, in the middle of big frame, be welded with crossbeam 23, draw ring 24 is welded on the crossbeam 23.

The utility model changes the deficiency of single cultivated plough for improving the agricultural mechanization degree, and improving farmland quality and efficient all has important function.The utility model can guarantee that the ridge of ploughing out is smooth, and hack is effective, quite in the past twice arable land effect of single plough.
