Description
Technical Field
The utility model relates to a maize picker technical field, specific theory relates to a stem ear of grain is received maize picker header concurrently and horizontal ear of grain stem pulling device is plucked to stem ear of grain.
Background
The arrangement form of the header of the corn harvester for harvesting stems and ears is mainly divided according to the arrangement form of ear pluckers, and the existing ear pluckers are all roller type and are divided into a longitudinal horizontal plucking roller, a vertical plucking roller and a transverse horizontal plucking roller. The longitudinal and horizontal picking rollers are longitudinally arranged in front and back, the compression degree of the stalks is small when the longitudinal and horizontal picking rollers pick the ears, so that the power consumption is low, the adaptability to different states of the stalks is strong, the work is reliable, and the picked ears have more bracts. The vertical picking rollers comprise a pair of oblique picking rollers, the compression degree of stems in picking is large, bracts of ears are more stripped, the working performance is better under general conditions, but the stems are easily broken to cause blockage under the conditions of large stems, inconsistent sizes and more water content. The horizontal type picking roller comprises a pair of horizontal type picking rollers which are transversely arranged, although the horizontal type picking roller is simple in structure and low in power, the horizontal type picking roller has a high ear biting rate and is easy to block, and more of the horizontal type picking roller is used for harvesting green feed corns.
The invention discloses a corn stalk and ear combined harvesting platform, which is an improvement on a horizontal ear-picking and stalk-pulling device, wherein ears are picked by using an ear-picking pair roller, stalks are pulled by using a stalk-pulling pair roller, and ear-picking and stalk-pulling are respectively completed by different pair rollers. The stalk is pulled out by the stalk pulling pair roller with large diameter, so the stalk is not easy to block, the harvesting operation speed is high, the corn stalk can be orderly fed into the stalk cutter, and the quality of the recovered forage is good.
The above application solves the problems of stem blockage and cluster breakage to some extent, but still has the following problems:
(1) The thread pitch of the ear picking double rollers is too large, so that the ears are easy to bite into the ear picking double rollers, and convex ribs on the surfaces of the ear picking double rollers are easy to crush seeds;
(2) The stalks are conveyed to the ear picking roller pair through the standing grain pulling chain, the feeding chain and the auxiliary feeder, and then are conveyed backwards to the stalk pulling roller pair through the ear picking roller pair, so that the structure is complex, the cost is high, the failure rate is high, and the stalks are easily gathered at the ear picking roller to cause blockage when the ear picking roller conveys the stalks backwards;
(3) The stalks are conveyed to the stalk pulling pair rollers by the ear picking pair rollers, the stalk pulling pair rollers actively bite the stalks by self, the problem of unsmooth stalk pulling exists, and the stalks are easy to break and not easy to reach and block due to the long distance between the stalk pulling pair rollers and the ear picking pair rollers.
