Description

Complete beet harvester

Technical field

The utility model relates to a kind of agricultural harvesting machine, the combining machinery device of especially relevant beet.

Background technology

Beet presses for complete beet harvester at the northern China establishing in large scale during its harvesting, to raise labour efficiency, reduce labour intensity.Existing complete beet harvester, generally has the frame crossbeam, wheel, the speed change chassis, diesel engine, cut the tassel device, excavating gear and pick up native conveying plant, for example Chinese patent literature CN2357475 discloses a kind of such structure, in this structure, it cuts the square box that the tassel device has the pair of engaged gears of being equipped with, main shaft and the brush-type tassel dish of cutting, square box is contained in the recess of one " U " shape chase, and by of the extension spring pulling of a direction to the side top, square box is at gravity, the support force of " U " shape chase and the pulling force of extension spring keep certain height down, thereby make and cut the tassel dish and remain on certain height, so that cut the height of tassel dish according to the beet shape adjustments, finish the tassel work of cutting.Because the power that square box is subjected in " U " shape chase is not on same straight line, extension spring easily makes square box offset to one side, it is dumb to cause square box to move up and down, even also cut the upper and lower mobile dumb of tassel dish, thereby when work, easily produce the unclean phenomenon of brush tassel, perhaps produce the phenomenon that reams the beet body.

Summary of the invention

The purpose of this utility model is to provide a kind of tassel dish of cutting to adjust the complete beet harvester of height up and down flexibly according to the beet shape.

In order to achieve the above object, the utility model is by the following technical solutions: a kind of complete beet harvester, has the frame crossbeam, wheel, the gearbox chassis, diesel engine, cut the tassel device, excavating gear, pick up native conveying plant and gathering unit, cut the tassel device and have gear-box, main shaft, travelling gear, brush-typely cut tassel dish and extension spring, travelling gear is contained in the main shaft upper end, the output gear of gear-box and travelling gear engagement, cut the tassel dish and be contained in the main shaft lower end, main shaft has axle sleeve outward, be rotatably assorted by bearing between main shaft and the axle sleeve, axle sleeve has the sleeve of joining with the sleeve outer circle cunning outward, sleeve is fixed on the frame crossbeam, the sleeve upper end has the through hole that can supply main shaft to pass, the sleeve upper end is rotatably assorted by bearing and travelling gear, the travelling gear endoporus has internal spline, this internal spline matches with the external splines on main shaft top, the corresponding both sides of sleeve have axial long hole, one end of connector passes axial long hole and axle sleeve top is connected, the other end is positioned at outside the sleeve, and be connected with an end of extension spring, the other end of extension spring is connected with the frame crossbeam.

After adopting said structure, because two extension springs are held axle sleeve and are symmetrically located at sleeve and the both sides of axle sleeve, make axle sleeve be subjected to making a concerted effort of making progress all the time, and the cylindrical of axle sleeve is joined with sleeve endoporus cunning, sleeve play the guiding role to axle sleeve, deflection not when axle sleeve is slided up and down, so axle sleeve can keep certain height under the elastic force effect of gravity and extension spring, cut the tassel dish and also just remain on certain height, when cutting the tassel dish and run into top of sugar heet, ornamental tassels is just brushed away, when running into the beet body, the convex shape of beet body is easy to push away cutting on the tassel dish, makes and cuts the tassel dish, main shaft and axle sleeve rise, to avoid injuring the beet body; In case cross this beet body, gravity makes again to be cut the tassel dish and descends, so that brush away another top of sugar heet, can adjust height up and down neatly according to the beet shape owing to cut the tassel dish, thus brush tassel totally thorough, and do not hinder the beet body.
