Abstract

The utility model relates to a harvester repeated cutting apparatus which can respectively cut straw and ear of cereals, which is composed of a cutting device and an adjustment device; the cutting device composed of a cutter and a driving device is arranged between a cutting table and a front bridge of the prior art harvester. The adjustment device is composed of an adjustment chain and a following ring; the cutting device is hung at the lower part of a driving table of the harvester by the adjustment chain, and is in slide connection with the cutting table of the harvester by the following ring. The utility model is characterized in that the cutting table can be freely lifted within a limit height; when the lifted height exceeds the limit height, the repeated cutting apparatus follows the prior art cutting table to move; thus, the utility model has the advantages of low and smooth straw cutting, small feed quantity, and convenient operation and adjustment, and obviously improves work efficiency.

Description

The grain header repeated cutting apparatus

The utility model relates to a kind of grain header repeated cutting apparatus, for having the usefulness that grain combine cuts again now.

The cutter sweep of present known combine only has the individual layer cutter to constitute, and with the grain straw cut off and fringe feeding harvester inside together, finishes threshing and stalk is discharged.Its shortcoming be cut the stubble high, feed quantity is big, inefficiency.

And existing combine repeated cutting apparatus is to be made of cutter sweep and elevator.Cutter sweep is installed on the below of existing combine harvester cutting table, and two ends link to each other with the ceding of Taiwan by elevator.Its shortcoming is that stubble is high difficult fixing, and the height of the ceding of Taiwan must constantly be adjusted in the work, and the problem of bringing is that repeated cutting apparatus is moving thereupon, and it is high to readjust stubble, and is reverse operating, and the ceding of Taiwan raises, and repeated cutting apparatus decline, the ceding of Taiwan descend, and repeated cutting apparatus raises.When the ceding of Taiwan descended, the repeated cutting apparatus of prior art very easily contacted to earth and damages cutter.

For cutting technique that overcomes existing grain combine and the weak point of cutting technology again, the utility model provides a kind of stalk and fringe that can downcut cereal respectively, fringe is sent into grain header inside finish threshing, grain straw does not enter grain header inside, cut low and smooth, the simple to operate grain header repeated cutting apparatus of stubble.

The utility model solves technical scheme that its technical problem adopts: the utility model is made of cutter sweep and adjusting device.Cutter sweep is installed between the ceding of Taiwan and grain header propons of prior art combine, and cutter sweep is made of cutter and drive unit.

Drive unit is by the driving wheel annex, connecting rod, and lever arm constitutes.The driving wheel annex is an eccentric body shaft.

Adjusting device constitutes by adjusting chain and phantom ring.Adjusting the length of chain can regulate.The two ends of repeated cutting apparatus hang under the bridge of under-cab by adjusting chain.And slide by phantom ring and harvester header and to link to each other.The effect of phantom ring is that the lifting of the ceding of Taiwan in constrain height does not influence repeated cutting apparatus, and when surpassing constrain height, repeated cutting apparatus will be by phantom ring and ceding of Taiwan servo-actuated.

The beneficial effects of the utility model are that feed quantity is few, the efficient height; It is low and smooth, easy to operate to cut stubble.

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment is as follows.

Fig. 1 and Fig. 2 represent the structure of the utility model first embodiment, are made up of cutter sweep and adjusting device.Cutter sweep is made up of cutter and drive unit, and cutter is made up of moving knife 1 and stationary knife 2.Cutter is installed on the carrier base 12 on the grain header propons 14 by support 11, and is fixedly prevented to swing by two fastening pull rods 13.Drive unit is by driving wheel annex 3,4, three actuating arms 5 of drive link, and 6, three lever arms 7 of intermediate connecting rod, moving knife connecting rod 8 constitutes.Driving wheel annex 3 is installed on that (seeing Fig. 3, Fig. 4), is an eccentric body shaft on the prior art grain header gap bridge output pulley 15.Gap bridge output pulley 15 passes through driving wheel annex 3,4, three actuating arms 5 of drive link, and 6, three lever arms 7 of intermediate connecting rod, moving knife connecting rod 8 drives moving knife 1 and swings on stationary knife 2, to downcut the stalk of cereal.

For cutter sweep is carried out lifting, high to adjust stubble, the utility model is provided with adjusting device.Adjusting device constitutes by adjusting chain 9 and phantom ring 10.The cutter sweep two ends hang under the grain header driver's cabin on the bridge 17 by adjusting chain 9, and slide with the prior art ceding of Taiwan 16 by phantom ring 10 and to link to each other.

When needs adjustment stubble is high, get final product adjusting the length increase of chain 9 or dwindling.Keep away when barrier when need, the ceding of Taiwan 16 can be raise rapidly, phantom ring 10 drive cutter sweeps raise together (as Fig. 5).

Fig. 6 and Fig. 7 are the diagram of second embodiment of the present utility model.Different is the below that cutter sweep is installed on the prior art ceding of Taiwan 16, and the ceding of Taiwan jackshaft that driving wheel annex 3 is installed in the prior art ceding of Taiwan 16 is imported on the belt wheel 18.Its adjusting device is identical with the first embodiment mounting means.
