Abstract

The utility model discloses a combine harvester header second auxiliary cutter. Elastic supporting rods (4) are movably arranged at the two ends of square steel (1) with nuts, an angle iron (2) is welded at the inner side end of the square steel (1), fixing cutters (6) are fixed at the lower end of the angle iron (2) with rivets in an equally spaced mode, moving cutters (7) are fixed on a cutter support (13) with rivets and placed at the inner side ends of the fixing cutters (6), a swing box (9) is arranged on the left and middle upper portion of the square steel (1) and connected with the cutter support (13) through a swing rod (11), and the header second auxiliary cutter is arranged at the rear end of a header first auxiliary cutter and placed on a baffle located at the front and middle lower portion of a combine harvester through the elastic supporting rod (4) and a supporting post (3). Due to the fact that a group of cutter blades, namely, the second auxiliary cutter, are additionally installed on the rear portion of the header, original harvested wheat stubbles are cut for a second time and scattered to the ground after being directly cut, load of the harvester is greatly reduced, mechanical idle work is reduced, the harvester runs fast, does not have machine blocking phenomenon, and is small in grain loss, and work efficiency is greatly improved.

Description

Combine harvester cutting table second mate cutter

Technical field: the utility model relates to a kind of combine harvester cutting table second mate cutter.

Background technology: at present, country forbids that wheat stalk burns, and avoids environment.Advocate energetically straw-returning, be conducive to fertilizing soil, promote crop growth, thereby straw-returning become the development trend of agricultural tillage from now on, the straw cutting apparatus of different model and structure also arises at the historic moment.Country is to wheat wheat stubble limitation in height 10-12cm now, and the length of therefore takeing in straw in cabin is 60cm, is exactly this effective dimensions 60cm straw length, the one, increase cracker, thereby strengthen load, amount of fuel is increased, wasted oil plant, harvesting speed is slow, and the 2nd, mechanical wear is serious, had a strong impact on the service life of machine, the 3rd, because the header charging is too many, easily cause the feed system card machine, form traffic congestion, cleaning and maintenance are lost time, and delay work and mistake, and have affected the harvesting progress.

The utility model content: the utility model has overcome the drawback that present combine exists, provide a kind of and installed one group of blade additional at ceding of Taiwan rear portion, can carry out secondary to former harvesting wheat stubble and cut and cut, reduce the load of grain header, reduce the combine harvester cutting table second mate cutter that idle work uses.The technical scheme that the utility model adopts for achieving the above object is: its elastic fulcrum bar 4 use nuts are movably arranged on square steel 1 two ends, angle bar 2 is welded on square steel 1 medial extremity, stationary knife 6 use rivets equidistantly are fixed on angle bar 2 lower ends, moving knife 7 use screws equidistantly are fixed on knife rest 13, and be placed in stationary knife 6 the inners, swing case 9 and be arranged on square steel 1 left top, and are connected connection with knife rest by fork 11, ceding of Taiwan second mate cutter is arranged on the secondary cutter of the ceding of Taiwan one rear end, and is placed on the baffle plate of the front middle and lower part of combine by elastic fulcrum bar 4 and support column 3.

The beneficial effects of the utility model are: be second mate's cutter owing to having installed one group of blade additional at ceding of Taiwan rear portion, former harvesting wheat stubble carried out secondary cut and cut, and directly cut cut after just unrestrained ground, greatly reduce the load of grain header, reduce the idle work that machinery is done.Set up elastic fulcrum bar, the easy ditch of crossing in bottom easily will paste the ground wheat stalk and pick up chopping, the stability when having guaranteed work, and run a good foot, the machine of not choking, lose grain less, greatly improved operating efficiency.

Description of drawings: Fig. 1 is the straw cutting apparatus schematic diagram.

Fig. 2 is turning cylinder cutting knife schematic diagram.

Embodiment: as shown in Figure 1 and Figure 2, its elastic fulcrum bar 4 use nuts are movably arranged on square steel 1 two ends, angle bar 2 is welded on square steel 1 medial extremity, stationary knife 6 use rivets equidistantly are fixed on angle bar 2 lower ends, moving knife 7 use screws equidistantly are fixed on knife rest 13, and be placed in stationary knife 6 the inners, swing case 9 and be arranged on square steel 1 left top, and are connected connection with knife rest by fork 11, ceding of Taiwan second mate cutter is arranged on the secondary cutter of the ceding of Taiwan one rear end, and is placed on the baffle plate of the front middle and lower part of combine by elastic fulcrum bar 4 and support column 3.

As shown in Figure 1 and Figure 2, described stationary knife 6 is the half opening shape, built-in groove, and knife rest 13 is movably placed in groove.

As shown in Figure 1 and Figure 2, described angle bar 2 tops equidistantly arrange location-plate 8 with screw, location-plate 8 one ends and moving knife 7 flexible connections.

As shown in Figure 1 and Figure 2, described elastic fulcrum bar 4 upper ends arrange suspension ring 5, and spring 12 is movably placed in elastic fulcrum bar 4 middle parts, and elastic fulcrum bar 4 lower ends and square steel 1 are flexibly connected.

As shown in Figure 1 and Figure 2, described ceding of Taiwan second mate cutter is lower than the secondary cutter of the ceding of Taiwan one.

As shown in Figure 1 and Figure 2, the axle head of described swing case 9 arranges belt pulley 10, and is connected connection with main drive belt by belt.

Operation principle of the present utility model is: the original-pack blade adjustment of grain header is highly apart from ground 20cm, second mate's cutter positioning height reduces 10cm on the basis of last group of blade, original-pack like this blade first gathers in, actual harvesting straw is 60cm, take in the storehouse and carry out threshing, second mate's cutter is cut harvested wheat stubble and is cut 10cm, and the 10cm straw that cuts away just no longer advances grain header but directly trickles down ground, by actual effectively straw 20cm, can reduce the workload of grain header nearly 1/3rd, grain header per hour can increase the wheat harvesting area of 1-2 mu.
