The remote control video monitor is an infrared video monitoring remote control device for remotely controlling the operation of the combine harvester. The manual control platform is used for carrying out manual control under the condition that remote control is inconvenient.
When the sunflower disc, sunflower seeds and sunflower stem combine harvester capable of being remotely controlled is adopted, workers can operate the combine harvester in front of a computer monitor screen (or on a mobile phone) in a home, and the combine harvesting period can reach a harvested land block under the remote control of artificial intelligence to harvest. When harvesting, the working face of the sunflower disc moves forwards, the poking roller of the sunflower disc rotates to poke the downwards bent sunflower disc upwards gently, and then the sunflower disc enters the cutting piece (as the sunflower disc root part is static, when the sunflower disc enters the knife edge, the knife edge moves, the sunflower disc is pulled, and the stalks enter the narrow part of the knife edge to squeeze, so that the aim of scribing and cutting is achieved) (for more convenience and rapidness, the sunflower disc can be cut directly by the electric cutting piece). The cut sunflower discs are pushed into a sunflower rubbing roller by a later poking wheel to be threshed, and are sent into a storage box through a sunflower seed conveying groove, and after the storage box is fully stored, the sunflower discs can be connected into a bag from a sunflower receiving port at one side of the storage box. Or the storage box is jacked up by a hydraulic jack and is dumped into the transport vehicle to be pulled away. When the sunflower disc is cut off, the sunflower stems are cut off by the sunflower stem cutting sheet at the lower end, and pushed to one side to be placed on the ground (if the sunflower stems are not used as organic fertilizer in the ground, the sunflower stems can be crushed by a crushing roller and then spread into the ground to be used as fertilizer).
Cutting with a sunflower disc, threshing sunflower seeds and crushing sunflower stems. The sunflower disc, sunflower seeds and sunflower stem combine harvester has the advantages of remote control, safe and convenient use, and labor and time saving. The full manual operation is changed into remote control operation and manual operation, so that the method is more convenient and flexible, and saves labor and effort.
