Description

The herringbone plough of band clod-crusher

The utility model relates to the structure of the plough in the agricultural machinery, refers in particular to a kind of herringbone plough with clod-crusher.

Plough is important farm implements of finishing the farming of soil down tilt in the whole ground of agricultural or forestry, the plough of China mainly contains three kinds of forms at present, be single-beam plough, parallel plough, gangplow, the single-beam plough is meant that the plow frame of suspension ploughshare has only a crossbeam, though it can dig the soil and be split into large clod, but owing to have only row's ploughshare, therefore, the efficient of planing the ground is low, more shallow soil layer can only be opened, parallel plough is meant that the plow frame of suspension ploughshare is made up of two parallel crossbeams, and promptly ploughshare has two rows, therefore darker soil layer can be opened, its shortcoming be plane the ground inhomogeneous.Gangplow is meant that the girder of plow frame has multilayer, a plurality of, and therefore, volume is big, the cost height will be drawn by large sized tractor, generally is applicable to large-scale land reclamation, being not suitable for common peasant household uses, and three kinds of above mouldboard plows by syllabus all be as digging native machine, it can only open into large clod with the soil, in order to help the soil extensive use of chemical fertilizer and to improve emergence rate, generally also to harvesting and tillage machine large clod evenly be pulverized again, the whole soil of rake, so farming complex steps, the amount of labour is big.

The purpose of this utility model is to provide a kind of chevron shaped plough with clod-crusher, and ploughshare and clod-crusher are combined as a whole, and is evenly smooth with the soil scarifying of its farming, do not have large clod, simplified the ploughing work step, improved labor productivity.

The purpose of this utility model is achieved in that

A kind of herringbone plough with clod-crusher comprises plow frame, hanger bracket, under the plow frame ploughshare is housed, and it is characterized in that:

Plow frame is made up of the trapezoidal big frame of front end rectangle small frame and rear end, and this big frame is fixed in rear cross beam by two open backward cant beams and constitutes and be isosceles trapezoid;

Hanger bracket is made of pressure pin and pull bar, two supporting legs of pressure pin are fixed in the end face of the dual-side of plow frame small frame, its junction, upper end has linking arm to be connected with the lifter of tractor, there is the lambdoid pull bar that is backward junction, pressure pin upper end, and two tail ends of this pull bar are consolidated in the two ends of plow frame rear cross beam respectively;

In the upper and lower bearing block that stretch out backward at plow frame rear cross beam two ends, power transmission shaft and clod-crusher axle are housed respectively, two are parallel to each other and with the drive interlock, power transmission shaft connects uni-drive gear box, its position is last, the clod-crusher of helical blade shape is housed on the clod-crusher axle, its position is following, and the clod-crusher rear side is provided with block cover, and drive is provided with protective cover;

The gear-box of described power transmission shaft is connected in the line shaft of tractor with universal drive shaft, and this universal drive shaft is by the bearing block support that is contained on the plow frame.

The purpose of this utility model can also realize by following measure:

The lower end of described clod-crusher rear side block cover is scratched with hinge and is connected to baffle plate, and this baffle plate is by the compression spring reset that is sleeved on the pull bar, and this pull bar is contained in baffle plate bearing and the upper bracket.

Totally 7 of the ploughshares that described plow frame is installed down, its orientation is: each two of the left and right cant beams of plow frame, the plough point slopes inwardly; Every side is one under the plow frame small frame, and the plough point is outward-dipping; The small frame middle part is by 1 of the back lower place, and the plough point forward.

Described turnplow is fastened in plow frame with U bolt and becomes can change connection.

The utility model has following positive beneficial effect:

1, ploughshare is the herringbone distribution with plow frame, when loosening the soil large clod opened and concentrate to the centre, clod-crusher is positioned at the ploughshare rear, spiral vane is arranged on the clod-crusher, the large clod of concentrating can be blended, herringbone plough therefore of the present utility model loosens the soil ploughing and harrows whole these two processes of hack and combines dexterously, the associating farming, simplify the step of ploughing work, alleviated the workload that the smooth ridge in farmland is ploughed, improved labor productivity.

2, compact integral structure, tissue is reasonable, and cost is low, and is flexible, and easy operating uses small hand tractor can draw, be suitable for common peasant household and uses.

Now be described in further detail as follows in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is a structural representation of the present utility model, is front view.
