Header and harvesting system of millet harvester and millet harvester

Abstract

The invention discloses a header and a harvesting system of a millet harvester and the millet harvester, and belongs to the technical field of crop combine harvesting. The header of the millet harvester comprises a header rack, a reciprocating sickle, a left divider, a right divider and a header spiral auger, wherein the reciprocating sickle is transversely arranged at an inlet of the header rack, the left divider and the right divider are arranged on the two side edges of the inlet of the header rack respectively, and the header spiral auger is horizontally arranged on the back of the header rack. A reel is rotatably supported on a rear side cross beam which is transversely mounted on a picking rack. A transmission mechanism is in transmission connection with the reciprocating sickle, the header spiral auger and the reel. The harvesting system comprises the header and a controller used for controlling the header to move. The millet harvester comprises the header. Uncut crops and crops to be cut are effectively and forcibly separated without being wound, the crops to be cut are shifted towards the header without being thrown outwards, and cut crops are smoothly conveyed backwards into a feeding opening without being wound; moreover, applicability is high, the requirements for the millet of different heights can be met, and harvesting efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of combined harvesting of crops, and in particular relates to a harvesting table of a millet combine harvester, a harvesting system and a millet harvester. Background technique [0002] At present, there is no real millet combine harvester on the market, because it is very difficult to harvest millet. In summary, there are the following points before threshing: 1. The ear width of millet is very different, and the stalks under the ear of millet are also very different. The short ones are more than ten centimeters, and the long ones are seventy to eighty centimeters. As a result, the ears of millet have just bent down, and some have been bent to half; The toughness of the stalks is constantly changing, and the corn plants are tilted under the influence of the gravity of the ears, especially in autumn when the wind is strong, and the entangled stalks bring great difficulties to mechanical harvesting; It is di...

[0002] At present, there is no real millet combine harvester on the market, because it is very difficult to harvest millet. In summary, there are the following points before threshing: 1. The ear width of millet is very different, and the stalks under the ear of millet are also very different. The short ones are more than ten centimeters, and the long ones are seventy to eighty centimeters. As a result, the ears of millet have just bent down, and some have been bent to half; The toughness of the stalks is constantly changing, and the corn plants are tilted under the influence of the gravity of the ears, especially in autumn when the wind is strong, and the entangled stalks bring great difficulties to mechanical harvesting; It is difficult to determine the depth of the harvesting table due to such a large difference in plant height; 4. The length of millet ears varies greatly. The difference is that during mechanical harvesting, with the rotation of the reel, the ear of grain is thrown forward along the center of gravity under the action of centrifugal force, which is easy to cause a large amount of ear drop and the loss of header

5. Once the millet lodging occurs, it is difficult to harvest. The ears of millet are heavy, especially for varieties with long ear stems. hard to harvest

That is to say, the current millet harvester restructured from rice-wheat combine harvester or rapeseed combine harvester is not suitable for the depth of the header (the rice-wheat machine is too short, the rapeseed machine is too long), the grain divider is too low, too Short (easy to cause grain ears to hang on both sides of the header), the speed of the reel is too high and there is a gap between the reel teeth and the tooth bar (the ear stalks are entangled, and the ears are pressed down and are accidentally cut by the cutter), the header The diameter of the auger is too small and the rotation speed is too high (high-stalk crops are easy to entangle and the ears are easy to throw out) so that the ideal harvesting effect cannot be obtained
