Description

Baby combine

Technical field:

The utility model relates to a kind of agricultural machinery---grain header, particularly baby combine.

Background technology:

Existing baby combine, mainly by corn harvester structure, straw shift wheel, sheller unit, windmill, vibratory sieve and go out paddy mechanism, turn to and braking maneuver mechanism, manually connect grain supporting plate, driver's seat, frame, gear, running gear composition, there are some drawbacks in existing baby combine; The one, because its driver's seat is to link through separating mechanism and harvester, similar one is the lever construction of central pivot point with the sheller unit, when the driver takes driver's seat or disseat the operation grain header, meeting influence the cutter device lifting or fall, the upper and lower thereupon displacement of cutter, to make and cut the standing grain height and differ, influence harvesting matter grain; The 2nd, turn to and the brake operating device of existing small-sized combining is the steering linkage of the vertical both sides, driver's seat the place ahead that are placed in hand pulling type of pedal brake pedal, when running into the mud field, can not work for exempting from the cutting mill depression, the driver must descend the machine station to handle in grain header one side, and is very difficult; And, the eccentric stiffener complex structure of straw shift wheel, it is to drive the eccentric rotation of straw shift wheel by the several rows travelling wheel that turns round on eccentric annulus, in addition, the grain supporting plate that connects of existing small harvester is fixedly connected on frame, when the sheller unit lifting, the space length variation that goes out between the mouth of a valley and supporting plate that goes out the paddy device can not guarantee definite value, and influence connects the grain utensil and settles.

Summary of the invention:

The purpose of this utility model is to provide a kind of small harvester, overcomes the above-mentioned drawback of prior art grain header.

Technical solution of the present utility model is a kind of baby combine, mainly comprise corn harvester structure, straw shift wheel, sheller unit, windmill, vibratory sieve and go out paddy mechanism, turn to brake operating mechanism, connect grain supporting plate, driver's seat, frame, gear, running gear and form: (1) driver's seat is articulated on the frame through the elasticity movable arms, and the walking single wheel is equipped with in the driver's seat below; (2) turning to brake operating mechanism is to connect two stacked semilune pinch roller A, B by the control wheel center-pole, left and right two ends, pinch roller lower edge limit separately with the horizontal fork one end crimping of vertical rotation, the fork other end of A wheel crimping connects steering mechanism through steel cable, and the fork other end of B wheel crimping connects arrestment mechanism through steel cable.Straw shift wheel and the eccentric pendulum of crux are hinged, and eccentric center of oscillation axle and straw shift wheel central axes stagger, and be hinged through plate, and eccentric pendulum cross 4 ends are hinged through limit plate and connecting rod one end, and group straw end of the connecting rod other end and straw shift wheel is hinged.Connect the grain supporting plate and be articulated on the pallet stand, support is fixed on the sheller unit, and movable cushion block transfer supporting plate levelness is arranged between supporting plate and support.

Embodiment:

The utility model further specifies as follows in conjunction with specific embodiments:

A kind of baby combine, referring to accompanying drawing 1, mainly comprise corn harvester structure 1, straw shift wheel 2, sheller unit 3, windmill 4, vibratory sieve and go out paddy mechanism 5, turn to, connect grain supporting plate 7, driver's seat 8, frame 9, gear 10, running gear 11 and form with brake operating mechanism 6.

Driver's seat 8 is articulated on the frame 9 through movable arms 12, movable arms 12 middle parts via spring 13 be lifted on frame 9 after stretch on the cantilever 15 dress walking single wheel 14 on the movable arms 12 of driver's seat 8 belows.

Movable arms 12 is referring to accompanying drawing 2, it by armed lever 16 1 ends and tripod 18 one jiao by vertical hinged to pivot pin 17, tripod 18 is hinged on the frame 9 at relative horizontal sides two ends of angle therewith, the driver's seat 8 of this structure, the heavy grain of human pilot is by 14 carryings of independent rows travelling wheel, and the movable arms 12 of driver's seat 8 be connected in frame 9 after stretch on the cantilever 15, therefore human pilot take or disseat the perk that can not cause the anterior corn harvester structure 1 of grain header, fall, thereby guarantee that skive falchion movement is steady, avoid cutting the influence of standing grain height change and cut standing grain matter grain; When running into grain header simultaneously and need take a sudden turn significantly, very convenient, or when moving on the ridge arrow path of field, what can remove grain header top cuts standing grain and sheller unit, plays walking mechanism with the lever thick stick and with single wheel 14 carryings grain header is pushed away away.

Turn to brake operating mechanism 6 referring to accompanying drawing 3, it be center-pole 21 by control wheel 20 connect two levels stacked vertically to semilune pinch roller A and B, be installed on the frame 9, the horizontal fork 22 1 end crimping of the left and right two ends, lower edge limit of pinch roller A and vertical rotation, fork 22 other ends connect with steering mechanism through steel cable 25, the horizontal fork 23 1 end crimping of the left and right two ends, lower edge limit of pinch roller B and vertical rotation, fork 23 other ends connect arrestment mechanisms through steel cable 24.This turn to arrestment mechanism 6 when running into the mud field and need under the driver machine operation, operation is very easy and laborsaving, horizontal fork 22,23 middle parts a bit are articulated on the frame 9.

Straw shift wheel 2 is referring to accompanying drawing 4, one end of straw shift wheel 2 connects with the eccentric pendulum 26 of a crux, the

central shaft

28 and 33 parallel staggering of straw shift wheel central shaft of eccentric pendulum 26, two central shafts, one end is hinged through plate 27, eccentric center of oscillation axle 28 other ends connect thumb wheel transmission arm 29, cross 4 ends of eccentric pendulum are hinged through plate 30 with an end of a connecting rod 31 respectively separately, and connecting rod 31 other ends connect with group straw 34 1 ends hinge.The eccentric structure of this straw shift wheel 2 is very simple, is easy to make, and is firm not fragile.

Connecing grain supporting plate 7 is to be connected on the sheller unit 3 through pallet stand 35, and holder grain support 35 is that the horizontal edge frame by two ∏ shape frameworks is connected as one, and is the wishbone that level is dehisced, and the wishbone end of dehiscing is fixed on the sheller unit 3; Connect the middle part that grain supporting plate one end is articulated in the ∏ shape framework of wishbone bottom, the supporting plate other end is filled in transfer supporting plate levelness between supporting plate 7 and pallet stand 35 by correcting wedge 36.This grain supporting plate 7 that connects can guarantee out spatial altitude distance between the mouth of a valley and supporting plate, can regulate the supporting plate levelness simultaneously, and convenient the arrangement connects the grain utensil.

The advantage of the utility model small harvester is: the single wheel structure of driver's seat makes conveniently takes a sudden turn significantly, when on the ridge arrow path of field, walking, detachable again grain header upper unit, push away away grain header with lever with the single wheel carrying, turn to arrestment mechanism easy to operately, the straw shift wheel eccentric structure is simple, easily makes and firm, connect the height distance that the grain supporting plate can keep and go out the mouth of a valley, and adjustable water saving Pingdu, the convenient arrangement connect the grain utensil.
