Description
Technical field
The utility model relates to a kind of farm machinery, is specifically related to a kind of combine.
Background technology
The structure of existing combine mostly as depicted in figs. 1 and 2, its structure is reasonable inadequately, following problem can occur.
One, engine behind front wheel is in the operating desk below, causes the position of threshing cylinder must be arranged on the orientation that complete machine is taken back, and that is to say the top of left crawler belt.This structure is brought following harmful effect.
1, the right cane of the ceding of Taiwan carries elevator chain longer, causes the length of the ceding of Taiwan itself long.
2, the position of threshing cylinder is forced to raise, and causes the threshing mode can only adopt down the mode of threshing.
3, engine drives front-wheel, and causing in the process of advancing increases the wearing and tearing of crawler belt, and has reduced the tractive force efficient of engine.
4, cause the vibration of operating desk and even complete machine and noise magnitude excessive, in the service life of promptly reducing complete machine, had a strong impact on operator's operating experience again.
Two, since this cane transfer unit for threshing cylinder side on the lower side, cereal be with the cane transfer unit from the below of threshing cylinder by and by threshing., inconsistent under this structure with the threshing nail direction of motion on the threshing cylinder because the fringe head of cereal is sagging, cause the fringe head to be easy to fracture.Most foreign material impouring concave grate and piling up, the threshing system of existing half-feeding combine is open, most foreign material impouring concave grate, very easily result in blockage, cause a large amount of grain can not pass through concave grate, drop on foreign material on the contrary, and together discharge, caused the waste of grain with foreign material.And the foreign material that fly upward fly into cleaning and sorting system easily, and cleaning plant is resulted in blockage, and work is cleaned in influence.Very easily result in blockage, cause a large amount of grain can not pass through concave grate, drop on foreign material on the contrary, and together discharge, caused the waste of grain with the foreign material cane.And the foreign material that fly upward fly into cleaning and sorting system easily, and cleaning plant is resulted in blockage, and work is cleaned in influence.
Three, the cleaning and sorting system of the combine on the existing market mainly is made up of vibratory sieve, blower fan, attraction fan, secondary levels screw feeder, oblique screw feeder, Lysimachia sikokiana chain etc., and above-mentioned cleaning and sorting system structure is very complicated, and manufacturing cost and maintenance cost are all higher.And, taken very big space because above-mentioned parts all are installed in below threshing cylinder and the Lysimachia sikokiana chain, make the threshing cylinder rising height of having to.The threshing cylinder height is put, and the center of gravity of complete machine is raised, and influences the stability of complete machine, and has increased the hoisting depth and the difficulty of the ceding of Taiwan.And this kind threshing mode can be brought such as easy obstruction concave grate, cereal and together discharges problems such as causing waste with foreign material.
Four, in the design of the Lysimachia sikokiana chain structure of existing combine,, when the stem stalk is directly discharged, can be deposited on the standing crop, adopt segmentation to carry because cylinder is taken back, not smooth but this mode causes Lysimachia sikokiana chain junction to be carried easily, form and stop up.
Five, because the direction of motion of holding up the standing grain moving tooth of the ceding of Taiwan of existing combine is vertical with the direction of advance of grain header, for the lodging direction with hold up standing grain to dial the consistent crop of the finger direction of motion to be difficult to play the effect of holding up standing grain, to cause the harvesting difficulty of crop.
