Heavy double-side land preparation device
Technical field
The present invention relates to the soil preparation machine in a kind of agricultural machinery.
Background technology
Publication number be CN2552303's " Multifunction soil preparation machine " a kind of soil preparation machine is disclosed, as depicted in figs. 1 and 2, these facility have that complete machine configuration is reasonable, in light weight, reliable transmission, the steady safety of operation, operation quality is good, efficient is high, fault is few characteristics, once go to the field and can finish stubble-cleaning, rotary tillage, dark pine, ridging, suppression operation.But because need be rotary ploughing cutter shaft 11 and stubble ploughing knife pivot 8 certain distance that on fore-and-aft direction, staggers, make the center of gravity of rotary ploughing cutter shaft gear-box 17 and stubble ploughing knife pivot gear-box 7 certain distance that on fore-and-aft direction, also staggers, it is all asymmetric to make that the overall weight of soil preparation machine distributes on fore-and-aft direction and left and right directions, causes the distribution of weight of soil preparation machine imperfectly equalized.In addition, along with the development of Tendency of Agricultural Machinery in Chinaization, farm tractor power constantly increases, and objectively provides the support on the power for farm machinery improve ability to work.And at present the rotary ploughing cutter shaft and the stubble ploughing knife pivot of soil preparation machine are all shorter, and the width on the whole ground of single is very limited, drag the suspicion that existing soil preparation machine has " low load with strong power " with the tractor of high-power.Therefore be necessary to improve the ability to work of existing soil preparation machine.
Summary of the invention
The purpose of this invention is to provide a kind of heavy double-side land preparation device, improve the ability to work of soil preparation machine on the one hand, solve the imperfectly equalized problem of distribution of weight of soil preparation machine on the other hand.It comprises right plate 53, left plate 54, frame and main transmission box 51 that rear cross beam 55 and front beam 56 are constituted, main transmission box 51 is fixed on right plate 53, left plate 54, on the centre position of the rectangle frame body structure that rear cross beam 55 and front beam 56 are surrounded, riser 64 in the middle of it also comprises, left side stubble ploughing knife pivot gear-box 57, right stubble ploughing knife pivot gear-box 58, left-handed cultivated knife shaft gear case 59, knife shaft gear case 69 is ploughed in dextrorotation, left side stubble ploughing knife pivot assembly 60, right stubble ploughing knife pivot assembly 61, left-handed cultivated cutter shaft assembly 62, cutter shaft assembly 63 is ploughed in dextrorotation, left side rotary tillage power transmission shaft 65, right side rotary tillage power transmission shaft 66, left side stubble-cleaning power transmission shaft 67 and right side stubble-cleaning power transmission shaft 68, the two ends of a power take-off 511 of main transmission box 51 connect an end of left side rotary tillage power transmission shaft 65 and an end of right side rotary tillage power transmission shaft 66 respectively, the two ends of No. two power take-offs 512 of main transmission box 51 connect an end of left side stubble-cleaning power transmission shaft 67 and an end of right side stubble-cleaning power transmission shaft 68 respectively, left side stubble ploughing knife pivot gear-box 57 and left-handed cultivated knife shaft gear case 59 are arranged on the outer wall of left plate 54, right stubble ploughing knife pivot gear-box 58 and dextrorotation are ploughed knife shaft gear case 69 and are arranged on the outer wall of right plate 53, middle riser 64 is fixed on the centre position of frame below and is parallel to left plate 54 and right plate 53, in the middle of being connected in, left side stubble ploughing knife pivot assembly 60 is connected between riser 64 and the left plate 54 and with the power take-off of left stubble ploughing knife pivot gear-box 57, in the middle of being connected in, right stubble ploughing knife pivot assembly 61 is connected between riser 64 and the right plate 53 and with the power take-off of right stubble ploughing knife pivot gear-box 58, in the middle of being connected in, left-handed cultivated cutter shaft assembly 62 is connected between riser 64 and the left plate 54 and with the power take-off of left-handed cultivated knife shaft gear case 59, in the middle of being connected in, the cultivated cutter shaft assembly 63 of dextrorotation is connected between riser 64 and the right plate 53 and with the power take-off of the cultivated knife shaft gear case 69 of dextrorotation, left side stubble ploughing knife pivot assembly 60 and right stubble ploughing knife pivot assembly 61 coaxial lines, left-handed cultivated cutter shaft assembly 62 is ploughed cutter shaft assembly 63 coaxial lines with dextrorotation, the other end of left side rotary tillage power transmission shaft 65 and the other end of right side rotary tillage power transmission shaft 66 are connected on the power input shaft of left-handed cultivated knife shaft gear case 59 and the cultivated knife shaft gear case 69 of dextrorotation, and the other end of the other end of left side stubble-cleaning power transmission shaft 67 and right side stubble-cleaning power transmission shaft 68 is connected on the power input shaft of left stubble ploughing knife pivot gear-box 57 and right stubble ploughing knife pivot gear-box 58.
In the present invention, the direction of advance of definition soil preparation machine is the place ahead of soil preparation machine, thereby is the left side and the right side of the definite soil preparation machine of visual direction with the direction that whole machine advances.During work, the power of tractor output shaft at first is delivered to main transmission box 51, two power take-offs of main transmission box 51 power distribution in four gear-boxes that are arranged on the frame both sides equably, again by these four gear-boxes on transmission of power to four cutter shaft.Since four cutter shafts be about, front and back are symmetrically arranged, four gear-boxes also be about, front and back are symmetrically arranged, main transmission box 51 is positioned at the centre position of frame, therefore soil preparation machine is not laid particular stress in any one direction, the distribution of weight of soil preparation machine is in admirable proportion, and has improved the stability of soil preparation machine work greatly.The present invention has extended one times to rotary ploughing cutter shaft and stubble ploughing knife pivot, and ability to work and efficient have also strengthened one times naturally, matches with the tractor of high-power just, extremely is suitable for 120 horsepowers of tillage operations to 200 horsepowers of tractors.Characteristics of the present invention are: the workpiece moment of torsion that frame is firm, global design is rationally compact, transfer motion power disperses, be used for transmission of power is little, multinomial whole ground purposes such as can realize stubble-cleaning, loosen the soil.
