Abstract
The invention discloses a threshing constant-speed change drive box of a longitudinal axial flow harvester and relates to agricultural equipment. The threshing constant-speed change drive box is installed between a threshing room and an operation room. A gearbox support is connected with a threshing support above the position of a threshing air blower driven plate. A fourth shaft is a grass discharging cylinder driving shaft, and grass discharging and heading automatic clutches can be selectively installed. A third shaft is a threshing cylinder transmission shaft, wherein two gears are arranged on the shaft, during high-speed transmission, the shaft conducts rice harvesting correspondingly, and during low-speed transmission, the shaft can be used for threshing wheat, rape and other legume crops. Second shafts are two transition driving wheels. A first shaft is driven by an air blower, wherein the shaft is provided with two gears for controlling the high-speed and low-speed operation of heading, grass discharging and threshing mechanisms. The walking speed of the harvester is increased, the feeding amount is increased, the overall speed of heading, grass discharging and threshing is increased, the work effect cannot be changed, only the circumstances that a grain conveying auger and stepless speed change need enough flow are needed, the power reserve is sufficient, the walking traction is enhanced, the structure is strengthened, and a granary is enlarged. Accordingly, the purpose of manufacturing high-speed and large-feeding-amount harvesters is achieved.
Description
Technical field
Longitudinal axial flow harvester threshing constant speed change gearbox, relates to agricultural equipment manufacture.
Background technology
On July 28th, 2014, I proposes the patent application of longitudinal axial flow harvester threshing chamber improvement opportunity to State Intellectual Property Office, application number: 201410369213.1, and December 24 announced, publication No.: CN104221621A.This technology is refer in application.
Longitudinal axial flow harvester threshing chamber improvement opportunity, scientifically discloses the operation principle of threshing chamber of harvester, has filled up the defect of Kubo field grain header, substantially solves the phenomenon of " entrainment loss ", " blocking " of grain header.Feed quantity is improved.
Last century the eighties not, I used thresher, and the rated speed of thresher is exactly 1100 revs/min, but the speed of manpower Lysimachia sikokiana, more a lot of than present grain header Lysimachia sikokiana doubly.The rotating speed of harvester threshing drum, below 1100 revs/min, is to produce cereal fragmentation.Cereal broken with screw feeder speed, gap, screw feeder blade smoothness etc. factor relevant.
Grain header tackles the cereal of difficult threshing, as paddy rice, can strengthen Lysimachia sikokiana and threshing toothed bar linear differential (linear velocity difference is vector), strengthens threshing dynamics; To wheat, rape and other legume crop, threshing ratio is easier to, and linear differential wants less.To reduce the impurity in sorting screen.
The threshability of grain header, is determined by factors such as the linear differential of Lysimachia sikokiana and threshing toothed bar and assembling differences.Improve the bulk velocity of the ceding of Taiwan, Lysimachia sikokiana and separating mechanism, the effect of threshing does not have too many change.
Longitudinal axial flow harvester threshing chamber operation principle: material is in the moment entering threshing chamber, and threshing initial velocity is zero, utilizes the vertical impact of threshing toothed bar and rubs brush with the hands, completing the threshing of exhausted most regions cereal.Promote to clash on concave grate through grass guide board by threshing toothed bar again, take off again and tremble grass, cereal remaining in cleaning material.
The rotating speed of longitudinal axial flow harvester threshing cylinder can between 300-900 rev/min, and the rotating speed of transverse-axis-flow harvester threshing drum can only set between 600-900 rev/min.
Longitudinal axial flow harvester threshing chamber will a little spaciousness a bit, such flow just likely strengthens.Threshing chamber sieve can be lengthened to 30--35 and go through rice.Key wants the circulation of specification material, and the threshing cylinder of threshing chamber part, with closing style, prevents threshing bar band grass, results in blockage.Can analyze: the speed that ordinary material leaves Lysimachia sikokiana cylinder is about 2 meter per seconds, the linear velocity of threshing toothed bar is then more than more than 4.5 meter per seconds again.If threshing toothed bar can effective convey materials, that blocking is impossibility.
For this reason, I designs longitudinal axial flow harvester threshing constant speed change gearbox, and it is not problem that maximum feed quantity reaches 6 Kilograms Per Seconds, if also will strengthen feed quantity, will strengthen the diameter of threshing cylinder.Wish that full feeding harvester appears on the market early at a high speed, serving agriculture.
Summary of the invention
Longitudinal axial flow harvester threshing constant speed change gearbox, is arranged between operating room and threshing chamber.4th axle is Lysimachia sikokiana cylinder driving shaft, axle has the friction tight clutch discs with axle, clutch bouncing plate, friction plate, and also have the 7th dynamic cooperation 60 gear, gear one side of something connects friction plate.Vertical axial arranges clutch lever, and the 7th gear is by the 3rd gear drive.3rd axle is threshing cylinder power transmission shaft, and axle has the 5th gear and axle move and coordinate, the 6th change-speed gearing spline fitted, axially can be engaged transmission between the five or six gear.Second axle is transition splined shaft, axle has spacer sleeve in three, four gears, the 3rd gear drive the 5th gear, the 4th gear can with the 6th gear drive.First axle is by the transmission of ancient customs arbor, and the first gear coordinates with axle is dynamic, transmission the 3rd gear.Second stud gear and an axle spline fitted, first and second gear axially can be engaged transmission, and the second gear also can transmission the 4th gear.Gear coordinates available needle bearing or neck bush with axle is dynamic.
When second stud gear and four gear drives, threshing cylinder can select 459.7 and 560 revs/min
When second stud gear and the first gear shaft are to being engaged transmission, threshing cylinder can select 560 and 682 revs/min.
The size of gearbox can be determined with different type of machines, is generally: 45 × 22 × 54cm
Constant speed change gearbox partial parameters following (for reference):
1,3,5 gears are 60 teeth; 2,6 change-speed gearing 55 teeth; 4 gear 65-70 teeth: 7 gear 60 teeth
First axle input speed is 560 revs/min.。
The speed that threshing cylinder may occur is respectively: 459.7; 560; 682.
The speed that Lysimachia sikokiana driving shaft (and passive ceding of Taiwan) can occur is respectively: 459.7; 560.(calculating by rated speed during dynamic work)
3rd axle and the 4th wheelbase are from being decided to be threshing cylinder radius.
