Description

A kind of active disk knife zero-tillage anti-blocking cell cube

Technical field

The utility model relates to a kind of active disk knife zero-tillage anti-blocking cell cube that is applied on the sower, belongs to agricultural machinery technological field.

Technical background

Protective farming technique is the agricultural revolution that agricultural machinery combines with agronomy, domestic in Shanxi, 10 provinces and regions such as Hebei, the Inner Mongol carry out demonstration and promote and use.Facts have proved that conservation tillage has soil moisture conservation, increase soil fertility, reduce water erosion and wind erosion, inhibition sandstorm, reduce flow chart, reduce operating cost and remarkable economical, society and ecological benefits such as increase farmers' income.The no-till maize machine is mature on the whole at home, and wheat no-tillage planter, and particularly in the area of yielding two crops a year, the preceding stubble of sowing wheat is a corn, and solve that the stalk amount is big, anti-clogging, breaking are buried etc. is the problem that numerous scholars concentrate on studies always.This shows that be wheat no-tillage planter in the implementation of two crops a year area with the core of using protective farming technique, and anti-blocking, the cut-out of maize straw root stubble of wheat no-tillage planter are its key technologies.

The domestic and international at present research to no-tillage seeding facility anti-blocking technology mainly concentrates on passive type anti-block apparatus and powder actuated anti-block apparatus.Though various passive type anti-block apparatus are simple in structure, cost is low, to the bad adaptability of stalk overlay capacity, still is difficult to solve the blockage problem of stalk overlay capacity when big.As shovel formula breaking device, be only applicable to the hard stubble sowing of wheat field; Double-disk is cut a batch device, the chaffcutter weak effect, and long stalk is easy to hang to cause obstruction on the breaking ridge buster, the little or plot operation of stalk through pulverizing in the stalk amount only suits.The active anti-block apparatus of research generally adopts the flail knife or the hammer pawl formula cutter of high speed rotating at present, and its stationarity is poor, and consumed power is big, and the rotating speed height is that have even higher, owing to be high speed rotating, safety, dust problem in the operation process become increasingly conspicuous.

Summary of the invention

The purpose of this utility model provides a kind of active disk knife zero-tillage anti-blocking cell cube, uses the no-tillage seeding machine of this cell cube configuration to cut off stalk, root stubble by the active cutting disc, thereby prevents that plough from stopping up; Cut table soil, thereby reduce the amount of breaking ground of the no-tillage operation of plough.

Comprise in order to reach the technical scheme that this purpose takes: frame 4, the plough assembly 1 that is connected with frame 4, cutting disc assembly 2 and parallelogram lindage 3, it is characterized in that described cutting disc assembly 2 has the active cutting disc 5 of a reverse high speed rotating.

In the above-mentioned active disk knife zero-tillage anti-blocking cell cube, described cutting disc 5 embeds between the plough assembly 1.

In the above-mentioned active disk knife zero-tillage anti-blocking cell cube, described parallelogram lindage 3 comprises the connecting rod 9 of clutch disk cutter 5, the set bolt 10 of stationary links 9, stay bolt 11 and cover compression spring 12 and adjusting nut 13 thereon.According to the situation on the cutting disc 5 work faces of land, cutting disc 5 can fluctuate around set bolt 10, by the size of adjusting nut 10 definite compression springs 12, realizes that cutting disc 5 and ground clearance are adjustable.

In the above-mentioned active disk knife zero-tillage anti-blocking cell cube, described plough assembly 1 comprises left ditching shovel tip 15, right plough spear 18, and it is fixed on the plough seat 17 by stove bolt 16.For ease of left plough spear 15, right plough spear 18 and cutting disc 5 gap adjustment, trench digging seat 17 is provided with chute 14, thereby realizes the adjustable gaps between cutting disc 5 and the ditching shovel tip.

In the above-mentioned active disk knife zero-tillage anti-blocking cell cube, described cutting disc assembly 2 comprises square shaft 6, is installed in the cutting disc 5 on the square shaft 6, bearing 7 and bearing block 8, and power is by square shaft 6 inputs, thus the continuous reverse high speed rotating of realization cutting disc.

The utlity model has following advantage:

1. cutting disc embeds between the ditching shovel tip of the plough left and right sides, thereby has prevented that effectively trench digging from stopping up.

2. parallelogram lindage not only can be controlled the road clearance of cutting disc, by adjusting the compression spring, can effectively increase the soil nature of going into of cutting disc.

3. make up slidingtype about the plough spear adopts, not only be beneficial to and the cutting disc location, and be beneficial to and change.

4. adopt powder actuated anti-blocking, by adjusting rotating speed, blocking-proof result is more obvious.

5. the square shaft axle connects by shaft coupling between the cell cube, and it is adjustable to realize sowing line-spacing, is applicable to the different regions operation.

6. save raw material, reduced cost; Be beneficial to the further popularization that promotes conservation tillage.
