The requirement of different tillage forms on the consistency of the operation depth of the opener is successfully met.

Description

Dual spring controlling type plough copying device

Technical field

The utility model relates to agricultural machinery technological field, particularly a kind of plough copying device that is applied on the no-tillage seeding machine.

Background technology

In agricultural machinery technological field; The plough parts of no-tillage seeding machine are many to be connected with rigidity of frame, especially for wedge angle type plough, therefore; The trench digging degree of depth of plough will move up and down with the fluctuating situation of the soil surface of no-tillage seeding machine land wheel process; Be difficult to guarantee the uniformity of sowing depth, for fixedly ridge culture industry pattern is particularly evident, the soil surface fluctuating quantity on furrow and the ridge is generally bigger.Yet sowing depth is the key factor that influences crop yield, and for this reason, developing a kind of plough copying device that is applied on the no-tillage seeding machine is to have very much practical significance.

At present; The copying device that is adopted for solution sowing depth consistency problem has multiple; Comparatively commonly used is to realize profiling through linkages such as parallelogram; But the common problem that the feeler mechanism that is based on this principle exists is: contour wheel is installed in plough or front or rear position, can not realize synchronized profile modeling, thereby influences the profiling effect.In addition; The copying device that also has other is that the Hydrauservo System of passing through that 200410070115.4 " hydraulic servo automatic copying device of walking machinery " are invented is regulated the workbench height to realize profiling, though theoretical advanced like the patent No.; But a whole set of hydraulic system structure is complicated; Not only increased the cost of agricultural machinery, and failed to realize synchronized profile modeling equally, practicality is relatively poor.

Summary of the invention

The purpose of the utility model is to provide a kind of no-tillage seeding machine sowing depth that can realize consistent, improves the dual spring controlling type plough copying device of seeding operation quality.

In order to achieve the above object, the utility model provides following technical scheme:

A kind of dual spring controlling type plough copying device, it comprises plough 8, plough frame 1, wherein, said device comprises the plough fixed mount 2 that joins with the no-tillage seeding machine frame 9 of supporting operation; Symmetry is fixed in the contour wheel fixed mount 10 of plough frame 1 bottom, and contour wheel 7 is installed on the contour wheel fixed mount 10; Plough frame 1 top is provided with adjusting nut 4, is furnished with upper springs 3 between adjusting nut 4 and the plough fixed mount 2; Plough fixed mount 2 arranged beneath have lower springs 6, and are spacing by the shaft shoulder on the plough frame 1; Plough fixed mount 2 is connected through the gap spline pair with plough frame 1.

The beneficial effect of the utility model is:

1, the trench digging degree of depth of plough is not subject to the no-tillage seeding machine land wheel, and profiling is effective;

2, package unit is simple in structure, easy to operate;

3, can be used on all kinds of sowers highly versatile.

Therefore the utility model helps realizing the uniformity of sowing depth under all kinds of farming patterns, improves seeding quality, and then increases crop yield, promotes the development of agricultural machinery.

Embodiment

According to accompanying drawing the utility model is described further below.

As shown in Figure 1, the dual spring controlling type plough copying device of the utility model, it comprises plough 8, plough frame 1, contour wheel 7, contour wheel fixed mount 10, plough fixed mount 2,

spring

3 and 6, adjusting nut 4, U type card 5.Wherein, contour wheel fixed mount 10 balanced weldings are connected on the plough frame 1, and contour wheel 7 is installed on the contour wheel fixed mount 10 through rolling bearing.Plough fixed mount 2 is fixed on through U type card 5 on the no-tillage seeding machine frame 9 of supporting operation, spline 12 on the plough fixed mount 2 and the spline 11 composition gap spline pairs on the plough frame 1.Plough frame 1 top is provided with adjusting nut 4, is furnished with upper springs 3 between adjusting nut 4 and the plough fixed mount 2; Plough fixed mount 2 arranged beneath have lower springs 6, and are spacing by the shaft shoulder on the plough frame 1.

As shown in Figure 2, the dual spring controlling type plough copying device of the utility model, wherein, contour wheel fixed mount 10 symmetries are fixed in plough frame 1 bottom, and the both sides synchronized profile modeling has guaranteed good profiling effect.

Like Fig. 3, shown in 4; Spline 11 composition gap spline pairs on the dual spring controlling type plough copying device of the utility model, the spline 12 on the plough fixed mount 2 and plough frame 1 have limited the circumferential movement of plough 8; Simultaneously; Guarantee the axially-movable of plough 8, and then under the effect of lower springs 6, accomplished the profiling operation of plough 8 with moving up and down of operation surface relief through contour wheel 7.

The dual spring controlling type plough copying device of the utility model, in use: confirm the roughly screw-in degree of adjusting nut 4 according to the hardness situation of operation soil, make upper springs 3 and lower springs 6 all be in compressive state.When soil was hard, the screw-in depth that increases adjusting nut 4 was to increase the pressure of lower springs 6; When soil is soft, reduce the screw-in depth of adjusting nut 4, make the pressure of lower springs 6 be enough to guarantee that plough 8 buries gets final product.And when the plough 8 contact faces of land but before not starting working, the weight through no-tillage seeding machine makes lower springs 6 further compress, with the pressure of increase lower springs 6, is convenient to plough 8 and buries.In addition, when the recessed serious and plough 8 in the face of land was unearthed, upper springs 3 can play cushioning effect, avoids the impact between adjusting nut 4 and the plough fixed mount 2.

The dual spring controlling type plough copying device of the utility model is simple in structure, easy to operate, highly versatile, profiling are effective, is applicable to the no-tillage seeding machine that is complementary with various farming patterns.
