Detailed Description
The structure of the present utility model will be further described by way of examples with reference to the accompanying drawings. It should be noted that the present embodiments are illustrative and not restrictive.
A header folding device of a corn harvester, please refer to fig. 1-3, comprising a header frame, the header frame is composed of a header main frame 3, a left side frame 1 and a right side frame 5. The main frame of the header is a fixed frame and is used for installing a stalk cutting mechanism, a spike picking unit, a feeding auger and the like. The left side frame and the right side frame are respectively connected to the left side position and the right side position of the cutting table main frame after approaching through the left folding driving mechanism 2 and the right folding driving mechanism 4, the outer sides of the left side frame and the right side frame are respectively fixedly arranged on the left side shield and the right side shield, and the left side shield and the right side shield are respectively extended to the front end position of the cutting table forward to play a supporting role and prevent corn stalks from falling outwards. The left side frame and the right side frame can be turned inwards and folded above the main frame of the header under the action of the respective folding driving mechanisms, so that the width of the header is reduced, and the width of the whole harvester is reduced. The problem that a corn harvester with a wider cutting table can meet a vehicle coming from a lane in the process of running on a road is solved.
The left side frame and the right side frame adopt the same structural form, are arranged in a bilateral symmetry manner on the header, and when the left side frame and the right side frame are positioned at the horizontal positions on the two sides of the header main frame, the heights of the left side frame and the right side frame are lower than the height of the header main frame so as to reserve enough overturning movement space for overturning the left side frame and the right side frame to the upper part of the header main frame. The left folding driving mechanism and the right folding driving mechanism adopt the same structural form and are arranged on the cutting table in a bilateral symmetry manner.
The left folding driving mechanism and the right folding driving mechanism respectively comprise a folding driving oil cylinder 4.1, a supporting rotating arm 4.2, a driving arm 4.4 and two connecting arms 4.5. The two connecting arms are arranged in parallel front and back. The outer ends of the two connecting arms are fixedly connected with the front inner upper corner part and the rear inner upper corner part of the corresponding side frame respectively through welding, bolting and the like, the inner ends of the two connecting arms are rotatably connected with the corresponding end of the rear upper cross beam of the main frame of the header through a first pin shaft 4.7 arranged along the front-rear direction, and the first pin shaft forms a turnover center of the corresponding side frame. The lower end part of the driving arm is rotatably connected with the upper corner of the inner side of the corresponding side frame through a second pin shaft 4.6. The second pin shaft is fixed at the inner corner of the upper end of the corresponding side frame along the front-back direction. The upper end part of the driving arm and the upper end part of the supporting rotating arm are connected in a relatively rotatable manner through a third pin shaft 4.3. The lower end part of the supporting rotating arm is connected with the position, close to the end part, of the main frame of the header in a relatively rotatable manner through a fourth pin shaft 4.8. The supporting rotating arm is a bent arm arranged at an included angle (an obtuse angle larger than 90 degrees), so that the reinforcing connection effect of the side frame and the main frame of the cutting table is achieved, and the overturning stability of the side frame is guaranteed. The cylinder end of the folding driving oil cylinder is hinged with the position, close to the middle part, of the rear cross beam of the header main frame, and the cylinder end of the folding driving oil cylinder is connected with the third pin shaft in a relatively rotatable mode.
The working principle of the header folding device of the corn harvester is as follows:
when the corn harvester performs harvesting operation in a farmland, cylinder rods of two folding driving cylinders of the left folding driving mechanism and the right folding driving mechanism extend out, so that a left side frame and a right side frame are respectively positioned outside the left side and the right side of a main frame of the header, and smooth harvesting of the harvester is realized as shown in the figure 1; when the corn harvester runs on a road, in order to avoid the phenomenon that the harvester is too wide to influence a meeting vehicle, cylinder rods of the two hydraulic cylinders are retracted, and in the process of retraction of the cylinder rods, the driving arm and the supporting rotating arm drive the side frames to turn upwards and inwards around the corresponding turning centers, so that the left side frames and the right side frames are respectively turned and folded to the upper part of the left end and the upper part of the right end of the main frame of the header, the folding of the header frame in the width direction is realized, and the width of the header is reduced.
Although the embodiments of the present utility model and the accompanying drawings have been disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit of the utility model and the appended claims, and therefore the scope of the utility model is not limited to the embodiments and the disclosure of the drawings.
