Description

Put the bean cutter of shop voluntarily

One, technical field:

The utility model relates to the grain header of harvesting legume crop, specifically is a kind of bean cutter of putting the shop voluntarily.

Two, background technology:

The Northeast plantation rice bean area is big, and autumn is when gathering in rice bean, because shortage of manpower needs to use the rice bean grain header, used grain header is a colter formula rice bean grain header, installation colter under the plow beam, and being moved ahead by the carriage traction slices off rice bean.The problem that exists is: when colter moves ahead, in case run into barriers such as stone, will produce the phenomenon of dragging heap, overwhelm the beans seedling, damage beanpod: in addition, this grain header is placed on the field after crop is cut down, can not put the shop voluntarily, also need manually will cut the crop that is poured on the field and put together and be paved into heap, labour intensity is big.

Three, summary of the invention:

The utility model provides a kind of bean cutter of putting the shop voluntarily, drags heap when being used to solve the rice bean cutting mill harvesting of former usefulness, can not put the problem of shop voluntarily.

The technical scheme that its technical problem that solves the utility model adopts is: the bean cutter of putting the shop voluntarily comprises carriage, frame, gearbox, the tooth-like cutter of rotation, rake teeth; On the big wheel shaft of carriage sprocket wheel is installed; Gearbox is installed in above the frame, and the output shaft at two ends connects the tooth-like cutter of rotation by two conical tooths that are meshing with each other, and power shaft connects power transmission shaft; Rotating tooth-like cutter is the rotating disc that circular periphery has tooth; Frame connects the semiaxis of carriage by hitch frame, semicircle opening is housed below the front end to pick up the seedling device; Rake teeth connects the rake axle, and the rake teeth drive unit is equipped with between rake axle and the power transmission shaft in the movable rear end that is fixed on frame of rake axle; The rake teeth drive unit is made of eccentric shaft, pull bar, pull bar swing cover, and eccentric shaft is installed in the end of power transmission shaft, and eccentric shaft, pull bar swing are set with catch, is connected by pull bar between pull bar swing cover and the rake spool.

Beneficial effect: the utility model integral body is drawn by carriage, come the tooth-like cutter of driven rotary by sprocket wheel, power transmission shaft, gearbox, conical tooth, the frame front end is installed pick up the seedling device beans seedling can be held together to adjacent two hold together between, rotate tooth-like cutter and under the ridge, be rotated cutting on the outer side edges on the adjacent two ridges limit of advancing, rake teeth can be put the shop voluntarily with the beans seedling under the cutting, do not exist and drag the heap phenomenon, do not damage beanpod; Can reduce labour intensity.

The utility model is mainly used in the harvesting rice bean, also can be used for gathering in other beans.

Five, embodiment:

Fig. 1 is the utility model structural representation, and as shown in the figure, this bean cutter of putting the shop voluntarily comprises carriage, frame, gearbox, the tooth-like cutter 8 of rotation, rake teeth 9; Gearbox 5 is installed on the frame 4, and the output shaft 14 of gearbox 5 both sides respectively connects a tooth-like cutter 7 of rotation by two intermeshing

conical tooths

21,22, and power shaft connects power transmission shaft 13.Specifically be that output shaft 14 with gearbox 5 is connected with 21 of conical tooths, the output shaft 14 of conical tooth 22 is connected with 7 of tooth-like cutters of rotation.Rotating tooth-like cutter 7 has the rotating disc of tooth for circular periphery.Respectively have semicircle opening to pick up seedling device 10 below the front end of frame 4, rake teeth 9 connects rake axle 8, and rake axle 8 is fixed on the rear end of frame 4 by the fixture activity.Frame 4 drives the lifting of lifter drawing bars 12 control frames 4 by the semiaxis of hitch frame 6 connection carriages by the lifting arm 11 of carriage.In order to regulate the angle of frame 4 by operation, at the front end setting angle frame 16 of frame 4, angle frame 16 is connected with adjustment leading screw 17 pins of carriage, is used to regulate the angle of frame 4.Between rake axle 8 and the power transmission shaft 13 the rake teeth drive unit is housed, the rake teeth drive unit is made of eccentric shaft, pull bar 18,19, pull bar swing cover 15, eccentric shaft is equipped with catch 20, be installed in the end of power transmission shaft 13, be connected by pull bar 18,19 between pull bar swing cover 15 and the rake axle 8, pull bar is swung and is overlapped 15 and be fixed on the frame, and the side also has catch, drive rake axle 8 by the rake teeth drive unit, rake axle 8 drives rake teeth 9 and carries out work.Sprocket wheel 3 is installed in power transmission shaft 13 1 end ends, and when rotating under the drive of sprocket wheel, the eccentric shaft of installing on it is along with rotation.When turning to catch 20 when touching catch on the pull bar swing cover 15, the catch of pushing drawing rod swing cover 15 upwards rotates, the other end of pull bar swing cover 15 is to lower swing and drive pull bar 18, the other end of pull bar 19 is moved downward, the other end of pull bar 19 is upturned, rake axle 8 upwards lifts rake teeth 9 along with moving upward.When eccentric shaft was rotated further to certain position, rake axle 8 and rake teeth 9 fell under the effect of gravity, and the beans seedling that the tooth-like cutter 7 of rotation is cut off draws in together, realizes putting voluntarily the shop.

Fig. 2 is a gearbox and the syndeton schematic diagram that rotates tooth-like cutter in the utility model, as shown in the figure, output shaft of gear-box 14 connects disc type cutter 7 by two intermeshing

conical tooths

21,22, specifically be that output shaft of gear-box 14 connects a vertical conical tooth 21, this conical tooth 21 again with conical tooth 22 engagement of another one level, conical tooth 22 with rotate 7 of tooth-like cutters and be connected.Gearbox 5 is installed in above the frame 4, and casing is fixed on above the

crossbeam

23,24 of frame, and

crossbeam

23,24 is fixing with bolt and frame 4 respectively, and the distance between two

crossbeams

23,24 can be regulated according to actual operating position.

Fig. 3 is the structural representation that picks up the seedling device in the utility model, as shown in the figure, picks up the semicircle that seedling device 10 is rivered bend by reinforcing bar, and leave opening, be installed on frame 4 front end both sides, its effect is before tooth-like cutter 7 cuttings of rotation the beans seedling to be drawn in the middle of adjacent two ridges, is convenient to cutting.

Fig. 4 is the structural representation of pull bar swing cover in the utility model, as shown in the figure, and pull bar swing cover 15 axle sleeves for the band catch.

The utility model integral body is moved ahead by carriage traction frame 4, and when advancing, along with the rotation of the big wheel shaft 1 of carriage, the machine driving between sprocket wheel 2, sprocket wheel 3, the turning cylinder 13, gearbox 5 speed changes are come tooth-like cutter 7 work of driven rotary.Frame 4 is regulated by lifting arm 11, the lifter drawing bar 12 of carriage apart from the height on ground.During work, about two tooth-like cutters 7 of rotation lay respectively at the outside on adjacent two beans ridges, earlier draw the beans seedling in swing to adjacent two ridges centre by picking up seedling device 10 in the front, rotate that tooth-like cutter 7 rotations move ahead and the root to the beans seedling carries out cutting under the ridge in the outside on adjacent two beans ridges.Work by rake teeth driving device controls rake axle 8, rake teeth 9 between turning cylinder 13 and the rake axle 8, the beans seedling that cuts is down put together put the shop.Rake teeth 9 is along with the lift adjustment of frame 4 height apart from ground.

In order to make the utility model that maloperation take place in travels down or when not gathering in work, clutch and clutch handle 25 are installed between big wheel shaft 1 of carriage and sprocket wheel 2, by pressing clutch handle 25, can be with disconnected closing between big wheel shaft 1 of carriage and the sprocket wheel 2.When not needing to cut, big wheel shaft 1 of carriage and sprocket wheel 2 disconnections are got final product.
