Abstract
The utility model discloses a double-edged rotary blade. A rotary cutting edge opening is respectively arranged at both sides of the soil rotational cutting part of the rotary blade, when the rolling blade rotates in positive direction or in the negative direction, the corresponding edge opening can cut rotationally the soil, the utility model is convenient for the machine operator, the time is saved, and the utility model is suitable for promoting that the straw stalk is returned to the field through using the rotary cultivator.
Description
Technical field
The utility model relates to a kind of agricultural machinery parts, particularly a kind of twolip rotary blade of using with rotovator.
Background technology
The rotary blade of rotovator adapted is the IS type at present, the IS type can only a direction rotary-cut soil, because early to bury batch effect with the reverse rotation operation better for field straw-returning cutter roller bearing, and paddy-field-working cutter roller bearing is rotated in the forward and is advisable, continuous development along with planting technology, paddy rice planting method is more, has paddy field rice transplanting, rice transplanting, water direct seeding live early.Several kinds of method for planting all appear in peasant household of village's group, and because of rotavator knife roller bearing forward or reverse will be adjusted the rotary-cut direction of rotary blade cutting edge, the tractor driver is unwilling to use, and has therefore increased the difficulty of promoting straw-returning.
Summary of the invention
The purpose of this utility model provides a kind of twolip rotary blade.
Scheme of the present utility model is: a kind of twolip rotary blade, the both sides that are in rotary blade rotary-cut soil portion all are shaped on the rotary-cut cutting edge.
The utility model twolip rotary blade need not dismantled when the cutter roller bearing rotates forward or backwards and adjust the rotary blade edge direction, saves trouble, and helps promoting using the rotovator straw-returning.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model front view
Fig. 2 is the utility model left view
Embodiment
Twolip rotary blade as shown in Figure 1 and Figure 2, both sides at rotary blade rotary-cut soil position all are shaped on cutting edge, corresponding cutting edge rotary-cut soil when rotating forward or backwards, the cutter roller bearing is all arranged, having solved needs dismounting to adjust the trouble of rotary blade cutting edge, the twolip rotary blade is installed on the patent No. ZL200720001544.5 buried batch reversing rotovator, the rotating operation of floods and droughts field cutter roller bearing, both do not change driving member and dismantled adjustment rotary blade edge direction yet, both greatly facilitated the tractor driver, saved the time, helped again promoting and use the rotovator straw-returning.
Claims (1)
1. twolip rotary blade, it is characterized in that: the both sides at described twolip rotary blade rotary-cut soil position all are shaped on the rotary-cut cutting edge.
