Description

Compound type rotary tillage multiple purpose aeroplane stubble-cleaning transmission device

The utility model relates to the soil cultivation machining machine and tool in the field machine.

In cultivated tillage operation machinery, the compound type rotary tillage multiple purpose aeroplane large tracts of land place in operation in agricultural production of once going to the field and finishing dark pine, rotary tillage, three operation functions of ridging becomes one of main separation type in the tillage equipment then, is subjected to the peasant and welcomes.In recent years, development and progress along with agricultural cultivating technology, the peasant presses for when compound type rotary tillage multiple purpose aeroplane is finished dark pine, rotary tillage, ridging operation, on same facility, increase and finish the stubble-cleaning operation function synchronously, promptly on facility, once go to the field and to bear and to finish the farming type of stubble-cleaning, rotary tillage, dark pine, ridging events in operation.At present, the structure design of setting up special-purpose stubble ploughing knife pivot on compound type rotary tillage multiple purpose aeroplane occurs, but, because its drive mechanism is not very reasonable, cause the invalid part of stubble ploughing knife pivot long, stubble ploughing knife pivot intensity difference, vibration be big, the transmission adopted two-stage chain-driving of the type that has, it is not steady to produce transmission, service life is short, and the disadvantage that fault is many, stubble-cleaning quality are difficult to guarantee.

The purpose of this utility model is exactly the technical matters at the existing transmission scheme that adopts during equipped special-purpose stubble ploughing knife pivot assembly on compound type rotary tillage multiple purpose aeroplane, design provides a kind of compound type rotary tillage multiple purpose aeroplane stubble-cleaning transmission device of new construction, by adopting the two-stage al-gear drive to make the transmission device of stubble ploughing knife pivot assembly high speed revolution, reach and reduce the invalid length of stubble ploughing knife pivot, increase cutter shaft intensity, the purpose that operation is vibrated, increased the service life, reduces fault, improves the stubble-cleaning effect that reduces.

Basic design of the present utility model is, in this stubble-cleaning transmission device, be provided with the transmission gearbox of two al-gear drives of firsts and seconds, be packed on the frame of compound type rotary tillage multiple purpose aeroplane, wherein the rear lateral portion of one-level al-gear drive case and main transmission box are directly affixed, and the active force output shaft of main transmission box is connected with the one-level power input shaft; Secondary al-gear drive case is configured in the end or the place, middle part of stubble ploughing knife pivot assembly, the stubble ploughing knife pivot assembly is connected with the second motive force output shaft, captiveing joint with the second motive force input shaft with the one-level power take-off shaft respectively in the two ends of torsion bar axle, so far constitutes the utility model basic structure.

Secondary al-gear drive of the present utility model design has that complete machine intensity is good, operation steadily, vibration is little, fault is few, long service life, characteristics that the stubble-cleaning quality is high.

Fig. 1 is a compound type rotary tillage multiple purpose aeroplane stubble-cleaning transmission device overall arrangement structural representation;

Fig. 2 is the side direction view of Fig. 1;

Fig. 3 is that the drive mechanism of compound type rotary tillage multiple purpose aeroplane stubble-cleaning transmission device launches scheme drawing.

Piece number explanation among the figure:

1, main transmission box, 2, one-level al-gear drive case, 3, torsion bar axle, 4, secondary al-gear drive case, 5, stubble ploughing knife pivot assembly, 6, frame, 7, active force output shaft, 8, one-level power input shaft, 9, one-level power take-off shaft, 10, second motive force input shaft, 11, second motive force output shaft.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.In compound type rotary tillage multiple purpose aeroplane stubble-cleaning transmission device, be provided with one-level al-gear drive case 2 and secondary al-gear drive case 4, wherein, one-level al-gear drive case 2 is packed on the frame 6, its rear portion and main transmission box 1 are affixed, and the active force output shaft 7 of main transmission box 1 is connected with the one-level power input shaft 8 of one-level al-gear drive case 2; Secondary al-gear drive case 4 is configured in the end or the place, middle part of stubble ploughing knife pivot assembly 5, and is packed on the frame 6, and stubble ploughing knife pivot assembly 5 is connected with second motive force output shaft 11; Captiveing joint with second motive force input shaft 10 with one-level power take-off shaft 9 respectively in the two ends of torsion bar axle 3, constitutes this stubble-cleaning transmission device.

When the stubble ploughing knife pivot assembly is finished the stubble-cleaning operation, main transmission box 1 passes to stubble ploughing knife pivot assembly 5 with the rotary power of trac. input through one-level power input shaft 8, one-level power take-off shaft 9, torsion bar axle 3, the second motive force input shaft 10 of secondary al-gear drive case 4, the second motive force output shaft 11 of active force output shaft 7, one-level al-gear drive case 2, realize the high speed revolution of stubble ploughing knife pivot assembly 5, utilize the stubble-cleaning cutter to finish stubble cultivation.Simultaneously, compound type rotary tillage multiple purpose aeroplane is finished operations such as the rotary tillage of soil, dark pine, ridging synchronously.This stubble-cleaning transmission device can be realized the structure exchange of transmission of two-stage chain cover and two-stage al-gear drive case, to satisfy the different requirements of different user.
