Abstract
The utility model relates to an agricultural mechanical equipment, in particular to a transverse cutter stubbing mechanism of the rotary cultivator, the utility model comprises cutting blades which adopt straight plate shapes, the cutting blades are fixed on a disc shape cutter frame, and the angular degree of the included angle between the cutting blade and the direction of the circumferential tangent line is more than 0 degree and smaller than 90 degrees. The utility model adopts the disc shape cutter frame, the cutting blades adopts straight plate shapes, not only the processing and manufacture are simple, but also both ends of the cutting blades and a rotary axle are fixed on the disc shape cutter frame in parallel, and the cutting blades are not easy to be dropped off; the whole cutter frame is formed by two semicircular steel plates which are fixedly connected through bolts, and the installation and disassembly are convenient; a plurality of cutting blades are installed on the cutter frame, the cutting blades and the direction of the circumferential tangent line form a certain angle, the rotating speed of the original rotary axle can be greatly enhanced when being used, the turning radius of the cutter edges are reduced, the depth of plunging into the soil is reduced, the resistance moment is small, therefore, the power consumption is reduced, and the stubbing effect is improved simultaneously.
Description
Technical field:
The utility model relates to agricultural machinery, particularly soil cultivation stubble-cleaning tillage implement.
Background technology:
Be extensive use of a kind of stubble-cleaning, rotary tillage, whole ground of ridging combination rotovator when putting the corn stubble in order in the agricultural production at present, blade is equipped with by bolt on the knife rest in the stubble-cleaning mechanism of this kind rotovator, the blade cantilever is fixed on the knife rest respectively at an angle, blade shapes is crooked L shaped, the stubble-cleaning blade turning radius is bigger, and it is darker to bury.In use plough bolt easily comes off, and blade becomes flexible or wearing and tearing promptly need in time to change blade, therefore exists the blade life cycle short, broken stubble weak effect, and tool changing bothers, and the operation resistance square is big, and consumption of power waits not enough problem more.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and the horizontal cutter stubble-cleaning of rotovator mechanism is provided, and has simple in structurely, and life cycle is long, and broken stubble is effective, and tool changing is easy, and advantage such as cut down the consumption of energy.
The technical scheme that the utility model is adopted for achieving the above object is: the horizontal cutter stubble-cleaning of rotovator mechanism, relate to blade, and blade is a straight plate shape, and blade is fixed on the disc knife rest, and blade and tangent to periphery angular separation angle are greater than 0 ° and less than 90 °.
Described blade and tangent to periphery orientation angle are 35 °-45 °.
Described disc knife rest cutter quantity is the 6-10 sheet.
Described blade is welded on the disc knife rest.
Described disc knife rest is to connect into disc by fixed block in the middle of two semicircles.
The utility model adopts the disc knife rest, and blade is a straight plate shape, and not only processing and manufacturing is simple, and blade two ends and rotating shaft secured in parallel be on the disc knife rest, the blade difficult drop-off; By the whole disk knife rest of the fixed formation of bolt, installing/dismounting power just with two semicircle steel plates for knife rest; A plurality of blades are installed on the knife rest, and blade and tangent to periphery direction are angled, can increase substantially the rotating speed of original rotating shaft during use, reduce the blade turning radius, embedded depth reduces, and the moment of resistance diminishes, thereby the reduction power consumption improves broken stubble effect simultaneously.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model and transmission mechanism assembling schematic diagram.
Embodiment:
The horizontal cutter stubble-cleaning of rotovator as shown in Figure 1 mechanism, the horizontal cutter stubble-cleaning of rotovator mechanism, relate to blade, blade 8 is a straight plate shape, eight uniform being weldingly fixed on the disc knife rest 9 of stubble-cleaning blade, blade and tangent to periphery angular separation angle are greater than 0 ° and less than 90 °, knife rest 9 is made by two blocks of semicircle steel plates, and during use, 10 butt joints form stubble-cleaning mechanism 4 to two semicircle knife rest groups of symmetry by bolt, stubble-cleaning mechanism 4 is fixed on the rotating shaft 5, be two ridge rotovators as shown in Figure 2, the ridge is corresponding stubble-cleaning mechanism 4 on line 3, and rotating shaft 5 two ends are hinged on the fixed head 1 by bearing 2, the overhanging bidentate sprocket wheel 7 that is equipped with in its two ends, sprocket wheel is driven by bidentate chain 6.
