Description
Technical field
The present invention relates to agricultural machinery, particularly straw crusher, specifically a kind of universal straw cutter of and combine coupling.
Background technology
At present, use straw crusher, can finish the overall process of field-crop from harvesting, threshing to the stalk fragmentation with combine coupling.The broken also field of stalk, or otherwise fully utilize broken stalk, be the effective measure of handling straw refuse.But find in using, because some disintegrating machines limitation structurally, so exist following weak point to some extent: as power bigger disintegrating machine, can only with large-scale rice/wheat combine coupling, the about 10-15 centimetre of crushed straws length can not satisfy the requirement of many-sided stalk comprehensive utilization; And some small-sized rice/wheat combines, can't drive high-power disintegrating machine operate as normal again, reluctantly operation also is intermittent, rice and wheat straw that per hour can only broken about 3 mu of ground, and it is motionless to meet the just basic cutting of moist stalk, disintegrating machine usually takes place by the stalk phenomenon of blocking.And the cutting dynamics of some low power disintegrating machines is poorer.In addition, the cutter structure of existing disintegrating machine is normally installed the cutter that revolves that is similar to rotovator on single shaft, and with the speed rotation that per minute 5000-8000 changes, flies out in case broken cutter fracture can be passed the shell of iron sheet material easily, has safety hidden danger; Also have the type variation along with combine, the installation rate of the disintegrating machine of existing model and rice/wheat combine is lower, and versatility is relatively poor.A kind of cracker that is referred to as hammer slice type is arranged, the rice wheat is had crushing effect preferably, but load is too big, use also influential to harvesting speed with the combine coupling; And its hammer slice axis running up down, because axis body concentricity deficiency, it is impaired that the violent shake that is produced is easy to fuselage, often used less than 1 year, and grain header grass outlet place is just torn to shreds.At to the problems referred to above, " a kind of and combine coupling stalk cutter " (patent No.: 200920048071.3 has been proposed applicant and in August, 2009; Application number: 200910034402.2).The advantage of this cutter mill is to install with the grass outlet of various rice/wheat combines is collaborative, power is little, energy consumption only is 3/10 of existing disintegrating machine, and chopping speed reaches per hour 7-8 mu, and the maximum length of chopping stalk only is 1-5 centimetre, go out the carelessness height, do not stop up, save comprehensive farming originally.But this cutter mill structure is complicated, requirement on machining accuracy is high, transmission system maintenance is bothersome, also is not the most desirable.
Summary of the invention
The present invention proposes universal straw cutter a kind of and the combine coupling, purpose is to pass through architecture advances, not only make the big or small rice/wheat combine coupling of this chopping function and various models, simultaneously can under higher efficient, lower energy consumption, finish stalks cutting, and structure is more simple.
