Description

Crop is sheared reaping apparatus

The utility model relates to a kind of agricultural machinery, is specifically related to the harvesting machinery of a kind of crop.

Harvesting machinery on the Tendency of Agricultural Machinery in China adopts large-scale grain header mostly at present, and this machinery must be applied in large-scale farm, the flat-bottomed land, and inapplicable for the crop in hills, area, mountain area.Some small-sized grain header adopts shoveling formula structure now, promptly in this mechanism, establish a shoveling, a wedge-shaped indentation that has certain circular arc is left in the shovel off-centered left position of front end, the end, and a pointed dentation blade is fixed on the breach limit, utilizes the power that promotes scoop to shovel and cuts crop.Though this device has certain applicability, have following shortcoming: 1. blade weares and teares easily, and shoveling easily pushes away motionless; 2. crop easily is stuck in and can not produces shovel among the wedge-shaped indentation and cut effect, the rice bar will be extracted with root if add high thrust by force.3. the shoveling rice cutting machine is owing to be provided with pay-off, and the rice bar that cuts that shovels is punch-drunk spilling in the field basically, need compile again during threshing.

The purpose of this utility model provides a kind of convenient and strength-saving, and blade is not easy to wear, and the harvesting ensuing crop is stacked neat crop and shears reaping apparatus.

The technical solution of the utility model is finished like this: whole device is divided into former and later two half-sections, depart from centre bit left at this bottom of device anterior half-sclerotome and install a wedge-shaped indentation, two bottom sides is established the anti-pulley that size diameter does not wait, join with axle, establish a bevel gear in the middle of the axle, another bevel gear with its engagement is established in the angular wheel shaft lower end, and circular shear blade is established in the stage casing, can mesh with the fixed blade that is arranged on bottom left, a swivel feeding frame is fixed in the angular wheel shaft upper end; The bottom caudal half-sclerotome is established material-storing frame, and a bucket-tipping device is established in the bottom, and a torsion pair of pages divider gate is installed in the material-storing frame side.

The utlity model has following technique effect:

1. blade adopts the rotational shear mode, and is easy to operate, laborsaving.

2. blade is not easy to wear, and the set reconditioning piece of its circular shear blade can keep the blade minister phase sharp.

3. the crop of shearing harvesting can neatly be stacked crop through the set frame bottom plate of swivel feeding frame and material-storing frame bottom.

4. the set antislip metal wheel in material-storing frame bottom is by not equal diameter left small and right large the bottom to be tilted to the left, and crop can be taken advantage of a situation after shearing lean to guardrail, and neatly move into material-storing frame under the cradle effect; Simultaneously get out of the way pocket at the bottom of the crop when low right high inclination angle, a left side can make crop be sheared, reduce resistance because the bottom produces.

The utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 1～5, the utility model car bottom 1 is fixing integral body, the bottom is divided into former and later two half-sections, be positioned at direction of advance keep left depart from center position have one the band circular arc wedge-shaped indentation, establish circular shear blade 8 and fixed blade 24 on the breach respectively, large pulley 18 and truckle 4 are established in 1 both sides, car bottom, and whole device is tilted to the left or to the right, are convenient to plant lodging.2 join with axle between two pulleys, fixing by supporting base 3, establish a bevel gear 6 in the middle of the axle 2, another bevel gear 5 is installed on the angular wheel shaft 7, with bevel gear 6 engagements, makes the lateral rotation of axle 2 change vertical rotation of angular wheel shaft 7 into.Fix a circular shear blade 8 in angular wheel shaft 7 stage casings, can mesh, form shearing condition with the fixed blade 24 that is arranged on 1 left side, car bottom.A cradle 10 is fixed in the upper end of angular wheel shaft 7, makes it produce swivel feeding and rotational shear synchronously.Topple over when shearing for preventing crop, shear ineffective, above fixed blade 24, establish guardrail 11, the top of circular shear blade 8 is established and is helped bar 28, make the crop supported at three point and the state of being kept upright, shear and carry out smoothly, crop after the shearing is driven by the cradle 10 of rotation and continues to move forward, and enters in the material-storing frame 13 that is arranged on half-section after the car bottom 1, and material-storing frame 13 is established a base plate 16, base plate lower link one pole 14, pole 14 links with rotating shaft 15 again, and handle 22 is enclosed within on the pivot pin 19, and turning handle 22 can make rotating shaft 15 drive pole 15, make pole 14 prop material-storing frame base plate 16, make it into an inclined-plane.When crop when breach enters, just can be subjected to the shearing of fixed blade 24 and circular shear blade 8, under the effect of cradle 10, pour material-storing frame 13 successively into, when being filled with crop in the material-storing frame 13, the operator can stir handle 22, by pole 15 16 of material-storing frame base plates is become the inclined-plane, the crop of having gathered in is pushed the torsion pair of pages divider gate 27 that is arranged on material-storing frame 13 sides open and pours ground into and finish under action of gravity after, torsion pair of pages divider gate 27 can self-returns.For ease of this moment operation, the utility model is established a depression bar 12 on the guardrail 11 of device middle part, links with handle 21, and depression bar 12 1 ends hold up the pin 25 of bar 28 tail ends to touch mutually with being arranged on.When depressing handle 21, depression bar 12 can push up pin 25 axial lines with pin 25, and under spring 26 effects in it is set, pin 25 tops are leaned on into guardrail 11, and the crop that does the front can not enter material-storing frame 13, is convenient to crop and neatly pours ground into.

For making things convenient for this device walking, turn to flexibly, fix an everything wheel carrier 17 in material-storing frame 13 bottoms, with everything wheel 20 admittedly thereon with pivot pin 19.

For in time repairing the blade of blunt, divide into a reconditioning piece 29 at circular shear blade 8, to keep the sharp of blade.

The utility model can also harvesting rape except that shearing harvesting paddy, wheat, buckwheat, also can shear cogongrass, reed etc.The power that is disposed can adopt foot-operated power (as shown in Figure 6), also can establish to push away with handle 23 and carry out shearing, and also can dispose minitype motivation, makes things convenient for the mountain area, and the knob peasant uses.

The utility model is simple in structure, and is convenient, flexible, is fit to the needs in vast rural area.
