A combine harvester profiling header for harvesting tall stalks and its lodging crops

Abstract

The invention discloses a combined harvester profiling cutting table capable of harvesting high stems and laid crops thereof. The combined harvester profiling cutting table comprises a cutting table frame, a cutting table forward stretching device, a feeding auger, a swinging ring mechanism, a horizontal cutter, a reel supporting arm, a triangular reel, a profiling grain lifting device and the like. The combined harvester profiling cutting table is mainly and structurally characterized in that the triangular reel is located above a horizontal cutter, the profiling grain lifting device is installed behind the horizontal cutter, and the front end of the profiling grain lifting device stretches out of the horizontal cutter. The harvesting requirement of high stems and laid crops thereof can be met, the novel profiling grain lifting device and the triangular reel are adopted, land profiling is achieved through the forward-stretching grain lifter, laid crops are supported, harvesting of the high stems and the laid crops thereof is achieved through the matching of the triangular reel and the horizontal cutter, and when the triangular reel dials in the high-stem crops, the grass winding phenomenon normally existing on a pentagonal reel can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of a combine harvester profiling header, in particular to a combine harvester profiling header for harvesting tall stems and lodging objects. Background technique [0002] When the combine harvester is working in the field, the driver must adjust the harvesting status in time by observing the terrain undulations and crop lodging while harvesting. The workload is heavy, it is easy to cause fatigue, and the work efficiency is low. Commonly used combine harvesters are generally pentagonal reels, which have better results when harvesting conventional low-stalk crops; but when harvesting high-stalk crops, pentagonal reels are easy to entangle grass, which has a great impact on harvesting efficiency. Impact. Chinese patent ZL201020170439.6 discloses a harvester reel anti-wrapping device. The scheme is mainly to add a protective plate at the side end of the harvester reel, and install the reel tube shaft and the r...

But for tall crops, pentagonal reels are not effective and less efficient

Chinese patent ZL201110197941.5 discloses a header of a rapeseed combine harvester. The header can realize the functions of cutting, dividing and pushing rapeseed plants at the same time in one operation. It has high functional integration, compact process, and low loss rate. However, the transmission is complicated, and it is not convenient to realize the flexible adjustment of imitating terrain and harvesting lodging crops

Chinese patent ZL201320630976.8 discloses a header profiling control system, one end of the profiling rod is installed on the angle sensor, the other end of the profiling rod hangs down on the ground by its own weight, and the profiling rod and the profiling rod at the movable connection end of the angle sensor The hydraulic system is connected. Both the hydraulic system and the angle sensor are connected to the programming controller. The programming controller judges whether self-profiling action is required according to the range of the received signal. The profiling device of this scheme is installed behind the horizontal cutter, although it can protect the However, when encountering undulating ground or ridges, there is still the danger of cutting the knife into the soil, which will reduce the working efficiency of the machine and shorten the life of the machine
