Description

Corn harvester ear-picking roll

Technical field

The utility model is related to farm machinery accessory technical field, more particularly to a kind of corn harvester ear-picking roll.

Background technology

At present, snapping bar is widely used on maize harvesting machine, and its operation principle is, during harvesting, with maize harvesting machine Advance, snapping bar leading portion guiding corn stem enter snapping bar stage casing gap, stalk between two snapping bars on one side axially It is mobile to be pulled downwardly on one side, fruit ear i.e. by snapping bar stop and plucked from.But existing snapping bar is limited due to structure, is caused There are the following problems when using：1st, feeding effect is poor；2nd, snapping bar easily skids in stem pulling, and easy damaged stalk；3rd, fruit ear is plucked Easily it is bruised from rear contacted with snapping bar.

Utility model content

In view of this, the utility model is directed to a kind of corn harvester ear-picking roll, and fruit ear is hindered can avoid squeezing, and can Prevent from pulling stalk.

To reach above-mentioned purpose, what the technical solution of the utility model was realized in：

A kind of corn harvester ear-picking roll, including roll body and the starting taper for being fixed on the roll body front end, in the roll body Outer peripheral face be provided with multistage spiral bar, the spiral bar is gradually big along the direction radial dimension away from the starting taper；Adjacent to institute State spiral bar, in the roll body tail end along its circumference be evenly equipped with it is a plurality of hale muscle, the muscle of haling is along away from the spiral bar Direction height it is gradually small, and smoothly connect with the tail end of the roll body.

Further, multiple passages are provided with the spiral bar.

Further, multiple teeth are provided with the leading portion for haling muscle.

Further, the direction width for haling muscle along the remote spiral bar is gradually wide.

Further, in being laid with a plurality of anti-skidding muscle in the circumference of the roll body, the anti-skidding muscle is located at the roller Multistage on body axial direction.

Further, multiple projections, the raised axial spiral shell along the starting taper are provided with the outer peripheral face of the starting taper Rotation arrangement, the rotation direction of the starting taper is consistent with the rotation direction of the spiral bar.

Relative to prior art, the utility model has the advantage that：

(1) corn harvester ear-picking roll described in the utility model, because the radial dimension of spiral bar is gradually big, can make snapping bar There is transient process to the pulling force of stalk and become larger, stalk can be avoided damage to, meanwhile, the height for haling muscle reduces, can be Fruit ear is plucked from rear, two snapping bars is diminished the extruding force of fruit ear, and fruit ear is hindered so as to avoid squeezing, and can have preferably makes Use effect.

(2) passage can promote the air current flow between two snapping bars, so that the stalk crushed descends slowly and lightly in time, can prevent Block snapping bar and shut down.

(3) teeth are set to be easy to pluck separating fruit fringe.

(4) width for haling muscle is gradually wide, it is possible to decrease hales extruding dynamics of the muscle to fruit ear, and avoids fruit ear from damaging.

(5) anti-skidding muscle is set snapping bar to be avoided to skid, it is ensured that drawing effect of the spiral bar to corn stem.

(6) projection can improve feeding effect of the starting taper to plant.

Brief description of the drawings

Constitute a part of accompanying drawing of the present utility model to be used for providing further understanding to of the present utility model, this practicality is new The schematic description and description of type is used to explain the utility model, does not constitute to improper restriction of the present utility model. In accompanying drawing：

Fig. 1 is the structural representation of the corn harvester ear-picking roll described in the utility model embodiment；

Description of reference numerals：

Embodiment

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can To be mutually combined.

Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

The utility model is related to a kind of corn harvester ear-picking roll, as shown in fig. 1, and it includes roll body 1 and is fixed on The starting taper 2 of the front end of roll body 1, is provided with multistage spiral bar 11, adjacent to spiral bar 11, in the tail of roll body 1 in the outer peripheral face of roll body 1 End is evenly equipped with along its circumference and a plurality of hales muscle 13.Wherein, spiral bar 11 is moved down for pulling corn stem, and hales muscle 13 Then be used for when fruit ear is pulled to and haled at muscle 13 by spiral bar 11, by fruit ear pluck from.

Specifically, the spiral bar 11 in the present embodiment is gradually big along the direction radial dimension away from starting taper 2, can so make Used time, make this corn harvester ear-picking roll that there is transient process to the traction force of plant and gradually increase, it is possible to decrease to jade The damage of rice stalk.Spiral bar 11 is specially that along the axial arranged of roll body 1, and the two ends of two sections of spiral bars 11 connect arrangement, Certainly, spiral bar 11 also can set three sections, four sections etc. except setting two sections according to the specific length of roll body 1.In addition, in spiral shell Revolve muscle 11 and be provided with multiple passages 111, to promote the air circulation between two snapping bars, the stalk of crushing is floatd in time Fall, shut down so as to prevent stalk from blocking the gap between two snapping bars.

The drawing effect to plant is reduced to avoid roll body 1 from skidding, it is a plurality of in being laid with the circumference of roll body 1 Anti-skidding muscle 12, and anti-skidding muscle 12 is the multistage on the axial direction of roll body 1, two sections of adjacent anti-skidding interlaced arrangements of muscle 12.For ease of Processing and manufacturing, the anti-skidding muscle 12 is specially vertical bar shape, certainly, and except using strip, anti-skidding muscle 12 also can be using the bar bent Shape structure.

The present embodiment hale muscle 13 along away from spiral bar 11 direction height it is gradually small, and with the smooth phase of tail end of roll body 1 Connect, further, hale muscle 13 along away from spiral bar 11 direction width it is gradually wide, thus, it is possible to decrease hale muscle 13 to fruit ear Extruding dynamics and prevent squeeze hinder fruit ear.Meanwhile, for ease of plucking from snapping bar, multiple teeth 131 are provided with the leading portion for haling muscle 13.

In addition, importing effect to the feeding of plant to improve starting taper 2, it is provided with multiple convex in the outer peripheral face of starting taper 2 21 are played, axial screw of the projection 21 along starting taper 2 is arranged, and the rotation direction of starting taper 2 is consistent with the rotation direction of spiral bar 11.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
