Abstract

The utility model discloses a crop combined harvester that can change the direction backwards and forwards, which belongs to the device of agriculture machinery. The structure of the crop combined harvester is that a header is arranged at the right front of the machine body; a front driving steering wheel and a rear steering wheel are respectively arranged in front and at the back of the lower part of the machine body; a roller-typed threshing device is installed at the middle part of the machine body, and a middle conveying device is coupled with the header and the roller-typed threshing device; a stalk-chasing wheel and a key-typed separation device are arranged at the rear part of the roller-typed threshing device; and a foreign-matter secondary threshing device, a riddling sieve, a granule impeller and a ventilator are arranged below the roller-typed threshing device; an internal semi-shaft is coupled with the driving-wheel shaft, and the internal semi-shaft is connected with the middle part of the driving-wheel shaft through a constant-angle-velocity universal joint; and a front driving steering wheel is arranged on the driving-wheel shaft and is fixed by a main pin.

Description

A kind of can before and after the crops combine that turns to

One, technical field:

The utility model relates to a kind of agricultural machinery, especially a kind of can before and after the crops combine that turns to.

Two, background technology:

Present crops combine, because the body height, size is big, and turning radius is big, and backpack combine body is long, causes short plot, narrow plot to gather in fully.Harvesting also can roll bad adjacent crops reluctantly.And easily cause contradiction dispute between adjoining farmland neighbour, the plot of the trees of especially in the farmland, planting.Because the influence of trees, crops can't be gathered in totally in the side near trees, moreover when woodland gathers in, grain header tune in stays can only unidirectionally be gathered in, and grain header is refunded after promptly having cut one time again, harvesting forward again, operating efficiency is very low, the very unwilling harvesting of operator of farm machinery.Damage trees, the phenomenon that breaks grain header takes place often.Customer has complaints, and the operator of farm machinery has complaint.In the course of time, formed all chance patch, short plot, woodland ground and hilly and mountainous land, grain header are refused into harvesting, have formed the grain header forbidden area in the course of time.Put in storage as if can not in time getting the harvest in quickly crops especially wheat, happen the cloudy weather for several days running sky and will cause great loss to the peasant.How the peasant expects that the combine that adapts to multiple ground condition can be arranged.

Three, summary of the invention:

The purpose of this utility model provide can adapt to that multiple ground condition gathers in a kind of can before and after the crops combine that turns to, it has solved the harvesting difficult problem that at present existing grain header exists, the purpose of this utility model is to realize like this.It is failed standing grain device, drum threshing device, is formed by straw wheel, driver's cabin, grain storage box, engine, key formula separator, back deflecting roller, assorted surplus secondary thrasher, sorting screen, seed pusher, fan, driving wheel bridge, inner shaft, CV joint, stub, live axle and the connection of front wheel driving deflecting roller by the ceding of Taiwan, centre, and the ceding of Taiwan is positioned at the positive front portion of body; Front wheel driving deflecting roller and back deflecting roller lay respectively at the front and back of underpart; Drum threshing device is installed in the middle part of body, and middle defeated standing grain device connects the ceding of Taiwan and drum threshing device; Grain storage box be positioned at drum threshing device directly over, engine is installed after grain storage box, driver's cabin is positioned at a side of grain storage box, is positioned at the rear portion of drum threshing device by straw wheels and key formula separator; It is down assorted surplus secondary thrasher, sorting screen, seed pusher and blower fan successively; Inner shaft is connected on the driving wheel bridge, and the centre of inner shaft and live axle is connected by CV joint; Follow the front wheel driving deflecting roller and be connected and fixed at the live axle first line of a couplet by stub.

During work, combine is sent into cylinder sheller by the defeated standing grain device in centre and is carried out threshing, cleans after the drive lower cutting table of engine is cut off crop, enters grain storage box then; Complete machine is in the following walking of the driving limit harvesting of front wheel driving deflecting roller; When turning to, front driving wheel is coordinated simultaneously to rotate with the back deflecting roller in opposite directions, need turn left to the time, the front wheel driving deflecting roller turns left, and back deflecting roller then turns right, and has both reduced the radius of turning greatly, increase steering flexibility again, can adapt to the harvesting of multiple ground condition crop easily; As short plot, narrow plot and woodland ground, even part hilly and mountainous land, the crop in terraced fields plot is the same can gather in; Break the forbidden area that to gather in of large-scale combine, can satisfy peasant's requirement and hope to greatest extent.The size that suitably reduces driver's cabin in addition will prolong the harvesting time greatly in order to increase the volume of grain storage box, further enhances productivity.

Four, description of drawings:
