Dredging type header for grain combine harvester

Abstract

The invention discloses a dredging type header for a grain combine harvester. A cutter is connected to the front end of a bottom plate, the cutter face of the cutter is parallel to the bottom plate, a dredging device is installed on the upper end face of the cutter in a stacked mode and is parallel to the bottom plate, the front end of the dredging device extends to the front of the front end of the cutter, two seedling dividing plates are fixed to two side plates in a one-to-one correspondence mode, meanwhile, the two seedling dividing plates are limited to the two sides of the dredging device in a one-to-one correspondence mode, dredging intervals are formed by the dredging device and the two seedling dividing plates, and reels are installed on the two side plates correspondingly and located above the position between the dredging intervals and harvesting intervals. According to the dredging type header for the grain combine harvester, in the plant harvesting process, disordered branches of disordered plants can be dredged into linear bundles, then the plants are cut off, and therefore the harvesting efficiency is improved, and the loss rate of rapeseeds is reduced.

Description

technical field [0001] The invention relates to the technical field of headers, in particular to a dredging header for a grain combine harvester. Background technique [0002] Rapeseed has tall plants, strong stems and many branches. The branches are intertwined and staggered. Ripe siliques are easy to fry. Its unique biological characteristics make the combined harvesting of rapeseed very difficult. At present, most domestic rapeseed combined harvesting is It is harvested by traditional grain combine harvester or modified on this basis, and mainly completes the functions of rapeseed harvesting, threshing, and cleaning. [0003] However, the traditional harvesting table directly cuts the stems of the plants through the cutter at the front end of its walking, and cannot effectively separate the stems that are entangled and pulled together, resulting in the inability to effectively cut the stems of the plants, resulting in low harvesting efficiency. Rapeseed branches are mech...

Problems solved by technology

[0003] However, the traditional harvesting table directly cuts the stems of the plants through the cutter at the front end of its walking, and cannot effectively separate the stems that are entangled and pulled together, resulting in the inability to effectively cut the stems of the plants, resulting in low harvesting efficiency. Rapeseed branches are mechanically pulled, which can easily cause shattering loss and fried pod loss. The uprooted rapeseed will also block the header, and the harvesting interval in the prior art is relatively shallow, resulting in the harvesting process. It is easy to cause the rapeseed to splash and rebound, resulting in a large loss rate of the rapeseed
