Description
Technical field
The present invention relates to a kind of agricultural machinery, be specifically related to a kind of double-shaft straw chopper.
Background technology
Straw cutting apparatus claims water, dry land to bury stubble (grass) harvesting and tillage machine again, wherein is divided into two kinds of single shaft straw cutting apparatus and double-shaft straw choppers again.
The operation principle of single shaft straw cutting apparatus is to change cutter to finish its transaction capabilities on the basis of former rotovator.Its major defect has:
One, rotating speed problem: the rotating speed of straw cutting apparatus requires to 260-310 rev/min.And the casing rotating speed of single shaft generally can only be about 215-280 rev/min at present, and the stubble-cleaning effect is difficult to reach optimum state;
Two, operating efficiency: the single shaft stubble cleaner is because be a coulter shaft operation, and a stubble-cleaning is difficult to meet the stubble-cleaning requirement during actual job, so efficient is low.
At these problems minority twin shaft stubble cleaner has also appearred in the market, though solved an above-mentioned part difficult problem, but increased new contradiction:
One, the transmission mechanism of all twin shafts all is the casing that utilizes former single shaft stubble cleaner, takes the method for single side face transmission, and its maximum weakness is that concussion property is big, the transmission torque is big, is subjected to force unbalance, occurs drive shafts fracture, frame deformation easily;
What two, some twin shaft side transmission was adopted is the V-belt transmission, only is confined to the nonirrigated farmland operation;
Three, also there are indivedual twin shaft side transmissions to adopt gearbox drive, but except comprising the said shortcoming of article one, also have because complete machine three gear-boxes occur and cause manufacturing cost to increase.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the double-shaft straw chopper of a kind of power output by the two-way output of intermediate gear box is provided.
The technical solution used in the present invention is: a kind of double-shaft straw chopper comprises idler gear box assembly, rotary ploughing cutter shaft assembly, stubble ploughing knife pivot assembly and framework; Described idler gear box assembly, rotary ploughing cutter shaft assembly, stubble ploughing knife pivot assembly are installed on the framework;
Described idler gear box assembly comprises intermediate gear box, power shaft, bevel gear, roller gear, carrier gear in the middle of the stubble-cleaning, carrier gear in the middle of the rotary tillage, stubble-cleaning spline gear and rotary tillage spline gear, bevel gear in described power shaft and the intermediate gear box is connected, bevel gear drives roller gear, roller gear drives middle carrier gear of stubble-cleaning and the middle carrier gear of rotary tillage simultaneously, carrier gear drives the stubble-cleaning spline gear in the middle of the stubble-cleaning, carrier gear drives the rotary tillage spline gear in the middle of the rotary tillage, the stubble-cleaning spline gear is connected with the stubble ploughing knife pivot assembly, and the rotary tillage spline gear is connected with the rotary ploughing cutter shaft assembly.
Its operation principle is: power is imported by power shaft, slows down and the change direction through bevel-gear sett, passes through a pair of roller gear again, passes to stubble-cleaning spline gear and rotary tillage spline gear by carrier gear in the middle of carrier gear, the rotary tillage in the middle of the stubble-cleaning respectively then.
The difference of the maximum of other type is on the present invention and the market: adopt the intermediate gear box transmission, thoroughly solved the side driving force apart from unbalanced shortcoming, intermediate gear box is gear drive.Whole box body is a seal form, not only can the nonirrigated farmland operation, can also paddy-field-working, and be not affected, garrulous soil rate, stubble-cleaning rate and flatness are very good.
In order to reach the stubble-cleaning optimum efficiency, through test of many times, comparison, the paring shaft rotating speed is generally 290～320 rev/mins, and the rotary tillage rotating speed is 210～350 rev/mins, so the gearratio of rotary tillage spline gear and stubble-cleaning spline gear is 1: 4.
The invention has the beneficial effects as follows:
One, stable performance: the power output of intermediate drive gear case is transmitted to two ends by two splined shafts (being stubble-cleaning colter splined shaft, rotary tillage splined shaft).Its torque is 1/2 of an one-sided transmission torque, and complete machine each several part weight is even, and running steadily;
Two, good airproof performance: tank body blank is a cast member, and it is whole to form sealing after operations such as processing, assembling, can cut off muddy water fully and invade when paddy-field-working, then can guarantee ne-leakage when the operation of nonirrigated farmland;
Three, versatility is good: all accessories in this gear-box are general part, and are simple in structure, and the tractor driver that generally can operate equal specification rotovator can skillfully use.And, maintenance, the same with rotovator, simple, the convenience of maintenance;
Four, cost is low: this gear-box collection trisome is an one.Promptly three gear-boxes of common twin shaft type are focused on the intermediate gear box, manufacturing cost reduces greatly, and dissipation power obviously reduces.
Five, efficient height: during general facility operation, at least need to plough and wholely just can reach the stubble-cleaning effect more than twice, these facility have adopted the mode that stubble-cleaning runs up, the normal speed of rotary tillage turns round, possesses the multiple operation function, generally speaking, no matter the paddy field still is the nonirrigated farmland only needs operation once just can satisfy the stubble-cleaning requirement.Operating efficiency is a times of other facility, is subjected to numerous tractor drivers' welcome deeply.
