Abstract
The utility model discloses a kind of corn picker stem pulling roller, it comprises two roll bodies, and roll body sidewall is provided with some mounting grooves angularly distributed, and has been bolted tool rest in mounting groove, tool rest be installed on be parallel to each other and near blade and stem pulling plate; Blade is parallel with roll body, and blade is positioned in the diametric(al) of roll body, and blade front end is provided with blade; Stem pulling plate inner end is provided with pilot hole, is provided with the guide finger inserted in pilot hole, is provided with pushing top spring between tool rest and stem pulling plate in tool rest; In two roll body rotary courses, the blade of the some blades on a roll body is supported mutually with another roll body sidewall successively.It adopts stem pulling plate to realize stem pulling, and blade realizes cutting, and compared with blade type stem pulling roller in the past, it is more stable to the pulling force of stem stalk, not easily skids, and harvesting efficiency is high, and stalk disintegrating is effective, and percentage of impurity is low, has practicality significantly.
Description
Technical field
The utility model relates to field of agricultural machinery, particularly relates to a kind of corn picker stem pulling roller.
Background technology
Stem pulling roller is a kind of parts conventional in corn picker corn snapping unit, and it orders about corncob with harvesting plate cooperating and is separated with stem stalk.The stem pulling roller of main flow only has the effect of downward tractive stem stalk, after corncob results, stem stalk still in a whole bar, must set up the object that stalk powder millstone just can reach go back to field in addition on reaping machine, and stalk powder millstone complex structure, power consumption are high, add the operating cost of combine.
In addition, also a kind of blade type stem pulling roller is had at present, it adopts blade to move down to clamp stem stalk, and can stem stalk be cut off machine in due course, but this stem pulling roller is in operation process, stem stalk easily cuts off by blade in advance, and can not provide larger traction force to stem stalk, finally causes harvesting can not be successful.It is low to there is efficiency of crop in it, and percentage of impurity is high, easily to drawbacks such as corncob cause damage.
Utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of reasonable in design, working stability, and harvesting efficiency is high, at the corn picker stem pulling roller that stem stalk is effectively cut into pieces by harvesting simultaneously.
For realizing above-mentioned technical purpose, the utility model adopts following technical proposals: a kind of corn picker stem pulling roller, comprise roll body that is two columniform, that be arranged in parallel, it is characterized in that: roll body sidewall is provided with some mounting grooves angularly distributed, be bolted tool rest in described mounting groove, described tool rest be installed on be parallel to each other and near blade and stem pulling plate; Described blade is parallel with roll body, and blade is positioned in the diametric(al) of roll body, and blade front end is provided with blade; Described stem pulling plate inner end is provided with pilot hole, is provided with the guide finger inserted in pilot hole, is provided with pushing top spring between described tool rest and stem pulling plate in tool rest; When described pushing top spring shrinks, the blade of blade is positioned at the front of stem pulling plate, and when pushing top spring stretches, the front end of stem pulling plate is positioned at the front of blade cutting edge; In two described roll body rotary courses, the blade of the some blades on a roll body is supported mutually with another roll body sidewall successively.
Described roll body sidewall is separately evenly equipped with filler strip, and when two roll bodies rotate, the blade of the some blades on a roll body is supported mutually with filler strip on another roll body sidewall successively, so avoid blade directly and roll body support and cause wearing and tearing.
The utility model has following beneficial effect: it can realize stem stalk to cut off in corn-cob picking procedure, thus without the need to installing stalk disintegrating equipment on corn picker, reduces the operating cost of grain header.It adopts stem pulling plate to realize stem pulling, and blade realizes cutting, and compared with blade type stem pulling roller in the past, it is more stable to the pulling force of stem stalk, not easily skids, and harvesting efficiency is high, and stalk disintegrating is effective, and percentage of impurity is low, has practicality significantly.

In figure, 1, roll body, 2, mounting groove, 3, filler strip, 4, tool rest, 5, blade, 6, stem pulling plate, 7, pushing top spring, 8, stem stalk, 9, blade, 10, guide finger, 11, pilot hole.
Embodiment
Shown in accompanying drawing 1-2, a kind of corn picker stem pulling roller disclosed in the utility model, comprises roll body 1 that is two columniform, that be arranged in parallel; Roll body 1 sidewall is provided with some mounting grooves 2 angularly distributed, and has been bolted tool rest 4 in described mounting groove 2, described tool rest 4 be installed on be parallel to each other and near blade 5 and stem pulling plate 6; Described blade 5 is parallel with roll body 1, and blade 5 is positioned in the diametric(al) of roll body 1, and blade 5 front end is provided with blade 9; Described stem pulling plate 6 inner end is provided with pilot hole 11, is provided with the guide finger 10 inserted in pilot hole 11, is provided with pushing top spring 7 between described tool rest 4 and stem pulling plate 6 in tool rest 4; When described pushing top spring 7 shrinks, the blade 9 of blade 5 is positioned at the front of stem pulling plate 6, and when pushing top spring 7 stretches, the front end of stem pulling plate 6 is positioned at the front of the blade 9 of blade 5; In two described roll body 1 rotary courses, the blade 9 of the some blades 5 on a roll body 1 is supported mutually with the sidewall of another roll body 1 successively.
In order to reduce the rate of wear of the blade 9 of blade 5, when described roll body 1 sidewall being separately evenly equipped with the rotation of some filler strip 3, two roll bodies, the blade 9 of the some blades 5 on a roll body 1 is supported mutually with filler strip 3 on another roll body 1 sidewall successively.
Operation principle of the present utility model is: when two roll bodies reversely rotate, stem stalk 8 contacts with stem pulling plate 6, there is provided lower pulling force to stem stalk 8 when stem pulling plate 6 rotates, along with the rotation of stem pulling plate 6, its spacing apart from another roll body is more and more less, so the elastic force overcoming pushing top spring 7 bounces back by it, thus the blade 9 of blade 5 is come out, when blade 5 move to contact with the filler strip 3 of another roll body 1 time, stem stalk 8 can be cut off, back and forth run thus, stem stalk 8 is cut into homogeneous segment.
