DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, with reference to the drawings and specific embodiments, a further description will be made of the utility model:
[0018] Please refer to Figure 1-2, The profiling device for the harvester cutting table according to an embodiment of the present utility model includes a cross-bridge panel 1 and a profiling frame 3. A cutting table inclination adjuster 2, a cross-bridge panel slideway 5, a cross-bridge panel oil cylinder pin 12 and a profiling frame support shaft seat 14 are welded on the cross-bridge panel 1. A cutting table lock pin 10 for locking with the harvester cross-bridge is welded on the rear side of the bottom of the cross-bridge panel 1. The profiling frame 3 is installed on the front of the cross-bridge panel 1. A profiling frame upper bearing seat assembly 6, a profiling frame lower bearing seat assembly 7 and a cutting table stop 4 are welded on the profiling frame 3. A profiling frame oil cylinder seat 13 is welded on one side of the lower part of the profiling frame 3. A cutting table lock piece 9 is installed in the lower side rectangular tube of the profiling frame 3. By the extension or contraction of the hydraulic cylinder in the present utility model, the profiling frame of the cutting table on the profiling device for the cutting table rotates slightly left and right with the profiling frame support shaft seat on the cross-bridge panel 1 as the fulcrum and the profiling frame upper bearing seat assembly 6 and the profiling frame lower bearing seat assembly 7 as the attachment points, so as to realize the profiling of the cutting table and the ground.
[0019] According to the above solution of the present utility model, the profiling frame upper bearing seat assembly 6 is sleeved with the cross-bridge panel slideway 5, the profiling frame lower bearing seat assembly 7 is in contact with the cross-bridge panel 1. A profiling frame support shaft sleeve 8 is provided on the lower side of the profiling frame 3. The profiling frame support shaft sleeve 8 is fixedly connected with the profiling frame support shaft seat 14 by bolts. A rotary oil cylinder 11 is provided at the bottom end of the cross-bridge panel oil cylinder pin 12. The rotary oil cylinder 11 is respectively connected with the cross-bridge panel oil cylinder pin 12 and the profiling frame oil cylinder seat 13, which is convenient for the assembly of the cross-bridge panel 1 and the profiling frame 3.
[0020] According to the above solution of the present utility model, the cross-bridge panel 1 is installed on the harvester cross-bridge through a cross-bridge lock piece. The cutting table of the harvester is hoisted on the profiling frame 3, and the cutting table lock piece 9 is locked with the harvester cutting table.
[0021] Working principle: The adjustment of the inclination angle of the harvester cutting table is realized by adjusting the length of the bolt on the cutting table inclination adjuster 2. When adjusted clockwise, the cutting table tilts upward. When adjusted counterclockwise, the cutting table tilts downward. When the rotary oil cylinder 11 extends, under the action of the rotary oil cylinder 11, the profiling frame 3 takes the profiling frame support shaft seat 14 as the fulcrum, and the bearing of the profiling frame upper bearing seat assembly 6 is in the cross-bridge panel slideway 5, and together with the bearing of the profiling frame lower bearing seat assembly 7, they support and roll on the contact surface of the cross-bridge panel 1. The cutting table and the profiling frame 3 rotate to one side by a certain angle (≤5°); when the rotary oil cylinder 11 contracts, the cutting table and the profiling frame 3 rotate in the opposite direction together (≤5°), and the cutting table reaches the initial position. When the rotary oil cylinder 11 continues to contract, the cutting table continues to rotate in this direction. After the rotary oil cylinder 11 retracts, the cutting table rotates to reach the maximum reverse angle (≤5°). Through the forward and reverse rotations, the cutting table changes with the terrain height during work, always maintains a suitable working height with the working surface, and the stubble height of the harvested crops is consistent, so as to achieve the profiling purpose.
