Abstract

The utility model relates to a three-part rotary cutter head of a sugarcane harvester, which consists of a shaft sleeve, a shaft, drive gears which are respectively arranged at the upper ends of the shaft sleeve and the shaft, a circular flat gear, a revolution gear and a cutter gear which are arranged in the cutter head at the lower end of the shaft sleeve and the shaft and are sequentially engaged with each other, and disc blades which are arranged on a cutter gear shaft. Power coming from a drive gear at the upper end of the shaft finally drives the disc blades to rotate to cut. Since a shaft sleeve drive gear drives the shaft sleeve to rotate and the cutter head rotates at the moment, three parts rotate for operation at the same time, the rotating speed of the disc blades is faster and the power is higher. Therefore, not only can the sugarcane harvesting efficiency be improved, but also the striking force of a straight-edge cutter to sugarcanes during harvesting can be eliminated, sugarcane roots can be kept intact and the stable and high yield of sugarcane fields can be ensured.

Description

Cane harvester three rotary cutting knife dishes

Technical field

The utility model is about the agricultural machinery parts, particularly about cane harvester three rotary cutting knife dishes.

Background technology

Cutter sweep on the general cane harvester is mostly on the cutterhead of disc, and radially installs and fixes the cutter of straight sword along this cutterhead.Circular motion is made in rotation by cutterhead, drives that cutter of straight sword breaks apart by chopping sugarcane on it.This cutter sweep is in the moment of cutter contact sugarcane bar, can give one on sugarcane bar impacting with sudden force, and this action can break the sugarcane root and stem of certain plants, batter down usually.The utmost point is unfavorable for the germinating growth of the sugarcane root and stem of certain plants in the coming year, and influences the output in sugarcane field.

The utility model content

The purpose of the utility model is to provide a kind of can cut sugarcane fast, reposefully, cane harvester three rotary cutting knife dishes that again can the intact retention sugarcane root and stem of certain plants.

The utility model has been taked following technical measures:

Have one to become discoid outstanding axle sleeve head to periphery with it fuses in the bottom of said pipe shape axle sleeve; Become steppedly to the cavity that is provided with a depression from the bottom surface of this axle sleeve head; And seal said cavity and constitute the flat box-like disc cutterbar of said circle with a round iron plate, in said axle sleeve, penetrate one; And make them become each other rotatably setting with one heart; In said disc cutterbar, the bottom of said axle is inlaid with a circle flat gear, is provided with a pair of respectively with the revolution gear and the cutter gear of revolution gear axle and cutter gear shaft at least with this circle flat gear with meshing successively; Prolong the lower end of said cutter gear shaft; And become to be inlaid with a dish-shaped cutting blade, respectively be inlaid with a travelling gear respectively in the upper end of axle and axle sleeve, also be provided with a dust cover at the outer surface of said disc cutterbar. with penetrating said round iron plate rotationallyConstituted the utility model therefrom.

In the utility model; Power drive lower end circle flat gear rotation from axle upper end travelling gear; Drive dish cutter tooth crop rotation and shaft transmission gear rotatablely moving in the same way through revolution gear again; Thereby drive dish-shaped cutting blade rotation, accomplish the sugarcane tip and the sugarcane root and stem of certain plants that the rotary-cut sawing of sugarcane bar are cut off sugarcane.At this moment, axle sleeve travelling gear drive axle sleeve and disc cutterbar rotate together in addition, have not only strengthened the strength of rotary-cut sawing, and can make the rotating speed of dish-shaped cutter faster through changing gear-driven speed ratio.The sugarcane bar is at this high speed rotating, and powerful sawing is disconnected sooner down, thereby has improved harvesting efficiency, and can eliminate in the past impacting of blade and make the sugarcane root and stem of certain plants of leaving over remain intact, thereby guaranteed the stable and high yields in the sugarcane field coming year.

Embodiment

Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model:

Description of reference numerals

1; Cane harvester three rotary cutting knife dishes 2; Axle sleeve 3; Axle 4; Circle flat gear 5; Revolution gear 6; Cutter gear 7; Dish cutting blade 8; Shaft transmission gear 9; Axle sleeve travelling gear 10; Axle sleeve head 11; Cavity 12; Round iron plate 13; Bolt 14; Disc cutterbar 15; Bearing 16 revolution gear axles 17; Cutter gear shaft 18; Bearing 19; Cutting blade bolt 20; Bolt 21; Dust cover 22; Bolt 23; End cap 24; Nut

Among the figure, the three rotary cutting knife dishes 1 of the utility model mainly are made up of axle sleeve 2, axle 3, oblate gear 4, revolution gear 5, cutter gear 6, dish-shaped cutting blade 7 and shaft transmission gear 8 and axle sleeve travelling gear 9.Axle sleeve 2 is one section round tube; Its lower end is provided with one and becomes discoidly to the outstanding axle sleeve head 10 of periphery with it with fusing; Become stepped to the cavity 11 that is provided with patty depression from the bottom surface of this axle sleeve head 10, the periphery of axle sleeve head 10 forms a downward chimb simultaneously, seals this cavity 11 with a round iron plate 12; With bolt 13 it is installed with on the chimb of axle sleeve head 10 simultaneously, has constituted the flat box-like disc cutterbar 14 of circle thus.Upper/lower terminal mouth of pipe place at axle sleeve 2 respectively is inlaid with a bearing 15, and bearing 15 inner rings snugly are provided with one 3 therewith, and this length of 3 is greater than the length of axle sleeve 2, and its two ends respectively make progress respectively, the upper/lower terminal from axle sleeve 2 stretches out downwards.In the cavity 11 of the lower end of axle sleeve 2, disc cutterbar 14, be inlaid with the round flat gear 4 of a diameter less than cavity 11 diameters; With a pair of revolution gear 5 of having at least of meshing successively of this circle flat gear 4 and cutter gear 6; Above-mentioned three gear diameter sums are greater than the radius of cavity 11, and revolution gear 5 is embedded in separately revolution gear axle 16 and cutter gear shaft 17 middle parts respectively separately with cutter gear 6, and on these two ends are installed in the band chimb respectively by means of separately bearing 18 axle sleeve head 10 and the round iron plate 12; Revolution gear 5 is provided with cutter gear 6 in pairs; Can be a pair of, also can be many circumference by five equilibrium cavity 11 to be provided with, in this embodiment; The lower end of three pairs of prolongation cutter gear shafts 17 is set; On said round iron plate 11, the position to should extension is provided with a through hole; Said cutter gear shaft 17 lower end extensions pass downwards in the hole thus; With dish-shaped cutting blade bolt 19 that dish-shaped cutting blade 7 (seeing the patent No. for details is: ZL 200820210787.4, and title is " bar stem crop dish cropping knife " specification) is on it fastening on the extension of each cutter gear shaft 17 lower end, and can be with cutter gear shaft 17 to rotate together.On the outer surface of the disc cutterbar 14 of axle sleeve 2 lower ends, be installed with one with bolt 20 and cover this surperficial dust cover 21, and with bolt 22 fixedly end cap 23 seal the bearing 15 of the upper end oral area of axle sleeve 2.Respectively be inlaid with the
