Description

Wide cut stalk cutter

One, technical field

The utility model relates to a kind of farm machinery, is specifically related to a kind of wide cut stalk cutter.

Two, background technology

Crops straw returning field helps increasing the organic matter in the soil, the structure of improving the soil, and culture fertility is eliminated the influence to sowing and farming.Machinery is cut throwing and can be enhanced productivity, and strengthens degree of crushing, and the area of scale establishing in large scale is had use value preferably.In cotton stalk cutter tool, usually adopt hobboing cutter to impact and cut throwing, the layout that cutter rolls mostly is vertical, also have horizontal, require hobboing cutter should have certain rotary speed and cutting impulse force, reach more than the cutting speed that can make cotton stalk fracture, power consumption is bigger, causes working width to be subjected to certain limitation.The general common 2-3 rice of cotton stalk cutter working width with car pusher-55 tractor-drawn.Continuous development along with the wide cut film-mulching cultivation technique, the sowing fabric width is commonplace about 5 meters, for realizing cutting polishing working with the width of cloth with rut with sowing, traditional cotton stalk cutter can not adapt to production requirement, and because the variation of cultivation mode, the wide cut cutter need adapt to different plantation line-spacing configurations and sowing fabric width, the reality production requirement is cut outside the fabric width that polishing working should have broad, to wide, the narrow versatility of cutter and the adaptability of different rows square setting is also had higher requirement.

Three, summary of the invention

The utility model is based on solve increasing working width and realize appropriate luffing and design, and the wide cut stalk cutter that provides a kind of fabric width adjustable is provided its purpose.

For achieving the above object, the technical solution adopted in the utility model is: a kind of wide cut stalk cutter comprises: hitch frame, road wheel, crossbeam, longeron and be consolidated in the below carriage constitute whole frame; Squirrel-cage combination cutter rolls by central shaft and links to each other with carriage, and the drive and the driving wheel belt transmission at central shaft middle part link, and driving wheel cooperates with the railroad traction output shaft by conical tooth case and shaft coupling and links to each other.Install horizontal supporting plate in the carriage bottom, and the type that the colludes flail knife under horizontal supporting plate front portion is provided with blade and the squirrel-cage cutter rolls matches.Described squirrel-cage cutter rolls that rimmer knife by a side rolls that short sword with opposite side rolls and secondary cutter rolls and constitutes; Hitch frame and crossbeam flexibly connect by bearing, and roll a side at the deflection rimmer knife and set up the inclined to one side bearing of traction.Front portion at described conical tooth case is provided with directional overrunning clutch, and fixed shaft coupling is set between conical tooth case and driving wheel.

The utility model characteristics are: the supporting plate of setting up and on fixed blade cooperate with flail knife on the hobboing cutter and form cutting angle, strengthen cutting effect, the required momentum of stalk fracture is reduced greatly, reducing unit stalk cutting power consumption, is that the wide cut operation becomes possibility under the onesize power output condition.And good by the whole steadiness of the fixed frame that forms of mainframe, carriage and lower pallet, for the wide cut operation provides safeguard.Long and short, the secondary cutter of combined type design rolls independently working, can arrange according to the fabric width needs, but the hitch frame installation site is adjusted in the translation of the biasing of setting up simultaneously traction bearing, realizes the luffing operation.Directional overrunning clutch can prevent effectively that cutter from rolling the destruction of inertia opposition to power take-off.As above design realizes wide cut, the adjustable polishing working of cutting of fabric width appropriateness, and can effectively protect transmission mechanism.Cotton stalk is thrown cut production efficiency by per hour 10 mu bring up to 50 mu.

Five, embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises road wheel 13, and hitch frame 15 flexibly connects by bearing 16 with mainframe crossbeam 1, constitutes whole frame by crossbeam 1 and longeron 2 and the carriage 3 that is consolidated in the below; The horizontal supporting plate 12 that installs in carriage 3 bottoms, and in horizontal supporting plate 12 front portions blade 22 is set and matches with the type that the colludes flail knife 17 that the squirrel-cage cutter rolls under 30,31,32.Described squirrel-

cage cutter rolls

30,31,32 and is Combination Design, the one side is that rimmer knife rolls 30, opposite side be short sword roll 31 and secondary cutter roll 32, rimmer knife roll 30 and short sword roll drive 5 on 31 in the relatively independent setting of central rack, and link with driving wheel 4 belt transmission simultaneously, driving wheel 4 matches with railroad traction output shaft 24 by conical tooth case 20 and mobile shaft coupling 23, and fixed shaft coupling 25 is set between conical tooth case 20 and driving wheel 4.And between conical tooth case 20 and mobile shaft coupling 24, directional overrunning clutch 21 is set.Secondary cutter rolls 31 and rolls 32 by being installed in spline housing 9 tandem drives on the carriage 3 with short sword.Described squirrel-

cage cutter rolls

30,31,32 structure at the two ends of central shaft disc an ancient measure 7 to be set vertically respectively, on totally 6 on disc an ancient measure 7 outer rim dead knife beams 10, support ring 8 is set in cutter beam 10 inside fixes strengthening, and is provided with on cutter beam 10 and colludes type flail knife 17.About two road wheels 13 slightly be down " splayed configuration ", the axle that turns of road wheel 13 inserts in the wheel carrier guide pin bushing 14 be fixed on the carriage 3.Operator is rolled a side and is set up deflective traction bearing 26 on crossbeam 1, and described traction bearing 16 and deflective traction bearing 26 are the fan-shaped ear that has position-arresting hole, and this position-arresting hole is in order to regulate the connection angle of hitch frame 15 and frame.

Power take-off 25 passes through portable shaft coupling 23, directional overrunning clutch 21, tapered tooth case 20, permanent coupling 25, driving wheel 4, drive 5 with power during the work of the utility model wide cut stalk cutter, drive the squirrel-cage cutter and roll the rotation of 30,31,32 forward directions, it colludes type flail knife 17 and forms the supporting cutting with fixed blade 22 on the supporting plate 12, throws that to cut the labor-saving effect good.Directional overrunning clutch 21 efficiencies prevent that cutter from rolling the reaction force of 30,31,32 inertia rotation to power take-off 24.

If need dwindle working width the time, the secondary cutter of this throwings cutter is rolled 32 dismountings, change supporting plate 12 into short supporting plate, will move in the right lateral travelling wheel 13, and hitch frame 15 moved to left on the deflective traction bearing 26 get final product.If the setting of sowing row is abnormal several ridge (as five duplicate rows), then rimmer knife rolls and can cut the stalk of throwing on the center line, realizes that symmetrical cutter rolls the nothing that can not finish and leaks operation.

As the another kind of situation of this wide cut stalk cutter, be to be symmetrical set rimmer knife to roll 30, the realization wide cut is stablized operation.

This wide cut cutter is particularly suitable for cotton stalk and cuts throwing, also can be used for the throwing of cutting of short stalks such as soybean.
