Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco harvesters, and in particular to a chassis tilt adjustment mechanism for hilly and mountainous areas. Background Technology
[0002] Currently, tobacco needs to be harvested after it has grown. However, harvesting in hilly areas is difficult and requires high-performance chassis.
[0003] Existing patent CN216397863U discloses a tilt angle adjustment mechanism for a rolling mill. It includes a left bearing seat and a right bearing seat for fixing the two ends of the forming roller, a left bearing fixing frame rotatably connected to the left bearing seat, and a right bearing fixing frame rotatably connected to the right bearing seat. An adjusting block is provided on the bottom surface of the right bearing fixing frame, and the adjusting block is horizontally slidable. The upper surface of the adjusting block is inclined and abuts against the bottom surface of the right bearing fixing frame. Because the adjusting block is located below the right bearing fixing frame, during operation, simply moving the adjusting block allows the right bearing fixing frame to move up and down, thereby adjusting the tilt angle of the forming roller, achieving adjustment without stopping the machine.
[0004] However, in practical application, the inventors believe that the following defects exist:
[0005] Disadvantages: (1) During use, the adjustment block needs to be moved so that the fixed frame can move up and down. Due to the different terrain in hilly and mountainous areas, the angle of the chassis needs to be adjusted during use. If it cannot be adjusted according to the terrain, it will affect the ease of use of the mechanism; (2) During use, due to the uneven terrain in hilly and mountainous areas, if the mechanism cannot be buffered and protected during use, it will cause damage to the mechanism and reduce the service life of the structure.
