Abstract

Single-ridge copying mechanism for soybean harvester makes it possible for the cutter to profile ridge and flexibly move vertically and horizontally so as to reduce harvest loss. The said aims are reached through setting oscillating ring at one end of transmission shaft, setting spline sleeve on the oscillating ring, forming spline matched with the spline sleeve at one end of rocker shaft and the rocker and hinging rocker driving cutter to the other end of the rocket shaft.

Description

Single-ridge copying mechanism

The present invention relates to a kind of harvest machinery, particularly a kind of reaping apparatus that is specifically designed to the machinery of results soybean.

Existing have harvest machinery of a great variety, from large-scale different to small-scale structure, function.For example, the combine that the results paddy and wheat is used, its structure is known, if but such harvesting machinery is used to accommodate soybean, then can have very big problem.Main cause is that the fruit of crop such as paddy and wheat is long on top, very long tangerine bar is arranged between from the root to the fruit, can be from any position cut-out of bar portion with most fruit harvest, soybean then is ridge culture, and the beans of all growing from top to bottom folder, therefore the characteristics of this crop have required the cutter of harvest machinery must the profiling along with the landform of ridge platform, and the position harvesting from very low so also can reduce field loss.Grain header with the results paddy and wheat does not obviously reach above-mentioned requirements, and is specifically designed to the mechanical actually rare of results soybean.

Disclose a kind of baby combine that is used to gather in the crops soybean the application's applicant in utility model patent 99204796.X number of application in 99 years, its cutter can tilt along with the height of ridge platform in lifting, thereby realizes the results of soybean.But the mounting structure of the cutter of above-mentioned grain header on header is unreasonable, simultaneously, because cutter is a rippling, one side is gathered in, therefore its transmission mechanism that drives cutter harvesting motion is provided with unreasonablely, easily cause the motion of cutter bad or stuck, thereby can't carry out the profiling harvesting.

The single-ridge copying mechanism that the purpose of this invention is to provide a kind of soybean grain header no matter how cutter rises and falls jolts, and can both allow cutter operate freely, thereby realizes the landform profiling of cutter upper and lower, left and right Sui Long platform, and field loss is reduced to Min..

Above-mentioned purpose of the present invention realizes by following structure, this single-ridge copying mechanism comprises: the header that is positioned at grain header the place ahead, be arranged on the cutter of described header lower front, described cutter by being separately fixed at the header both sides guide rail and in guide rail reciprocating guide pillar be connected on the header, it is characterized in that: be provided with the pendulum ring in the end of the power transmission shaft that is positioned at the header rear portion, have spline housing on the described pendulum ring, a rocker shaft is arranged on the cutter beam of cutter by block bearing, one end of rocker shaft has spline, match with the spline housing on the above-mentioned pendulum ring, the other end of rocker shaft is connected with the knife bar of cutter by rocking bar, drives cutter and moves back and forth.

Like this, when cutter gathers in along with tableland, ridge height rippling, because the lower end and the rocking bar of rocker shaft are articulated and connected, and the upper end of rocker shaft is to match with spline housing on being connected pendulum ring by spline, like this, no matter how cutter moves, when the distance of cutter and power transmission shaft changes, by the back and forth flexible length that just can regulate rocker shaft of spline in spline housing, and at the cutter dipping and heaving, when making the angle variation of rocker shaft, because rocker shaft and rocking bar are articulated and connected, therefore can change both angles freely, the motion of power transmission shaft successfully is delivered on the cutter, thereby realize harvesting efficiently.

Fig. 1 is mounted in the structural representation of the single-ridge copying mechanism on the header.

Among the figure: the 1st, power transmission shaft, the 2nd, pendulum ring, the 3rd, spline housing, the 4th, rocker shaft, the 5th, block bearing, the 6th, supporting base, the 7th, cutter beam, the 8th, rocking bar, the 9th, knife bar, the 10th, header, the 11st, guide rail, the 12nd, guide pillar.

Embodiments of the invention are described with reference to the accompanying drawings.

See Fig. 1, header 10 is the scraper bowl shape that (left side) tilts towards the place ahead, wherein is being provided with and is gathering in the crops mechanism's (not shown) that soybean is used.The power transmission shaft 1 that is being provided with at the rear portion of header 10 is being provided with pendulum ring 2 at a side end of this power transmission shaft 1, and the direction towards preceding bottom on described pendulum ring 2 is being provided with the spline housing 3 that is cylindric hollow, has spline on the inwall of these spline housing 3 hollow bulbs.The shaft-like rocker shaft 4 that has spline on back end outer surface is obliquely installed side at header 10 along the rear portion down to anterior direction, the rear end of this rocker shaft 4 is spent to be good for and is matched with the spline of described spline housing 3 hollow bulbs, and can be flexible back and forth in above-mentioned hollow bulb.On the position forward of rocker shaft 4 block bearing 5 is being set, this block bearing 5 is bearing on the cutter beam 7 of cutter by supporting base 6, moves with cutter.The articulated rocking bar 8 of the other end of described rocker shaft 4 (front end), one end of this rocking bar 8 (illustrated upper end) is hinged by pivot pin and rocker shaft 4, make that it can be around pivot pin driving angle in illustrated plane, the other end then is connected with the knife bar 9 of cutter by pivot pin, when described rocker shaft 4 is driven swing by power transmission shaft 1, stir cutter and move back and forth, realize the harvesting action.

The course of work to the single-ridge copying mechanism of this soybean grain header describes below.

When the harvesting soybean, the characteristics of this crop have required necessary close mowing, can reduce field loss like this.And, realize that close mowing must carry out Single-ridge copying because soybean is ridge culture, device of the present invention is finished under such requirement.

When the cutter profiling, cutter beam 7 moves up and down and causes that rocker shaft 4 rotates around power transmission shaft 1, be fixed on the variation that the distance of block bearing 5 and power transmission shaft 1 on the supporting base 6 of cutter beam 7 just takes place, and the change that also takes place of the angle of rocker shaft 4, therefore when rocker shaft 4 transmits moment of torsion, along with the profiling of cutter also will change itself length and supporting angle, otherwise cutter just can not carry out forming movement.

And use single-ridge copying mechanism of the present invention, as can be seen from the figure, because this device has adopted tipping spline housing 3 on the pendulum ring 2, rocker shaft 4 one ends form the such structure of splined shaft, allow splined shaft in spline housing 3, axially move, make rocker shaft 4 when transmitting moment of torsion, can also change its length at any time, and when the length of rocker shaft 4 changes, its supporting angle variation taken place, and connect rocking bar 8 in hinged mode by front end at this rocker shaft 4, thereby can change both angles along with the fluctuating of cutter, thereby successfully realize the Single-ridge copying of soybean harvesting, be controlled in the scope of soybean harvesting requirement cutting stubble.

In addition, because variation has also taken place the bearing angle of block bearing 5 when profiling, for fear of the interference of mechanism, block bearing 5 can adopt the UC bearing.
