Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an adjustable corn ear picking plate device. Background Art

[0002] In the prior art, a corn harvester is a device that performs multiple operations such as picking ears, peeling, threshing, and stalk chopping and returning mature corn to the field at one time. Usually, a cutting table is provided at the front end of the corn harvester, which is used for picking ears of corn while it is growing. During operation, as the corn harvester moves, the corn stalks are fed between the two ear picking plates of the cutting table. A stem pulling roller and a stem cutting wheel are provided under the ear picking plate. The stem cutting wheel is used to cut off the corn stalks from the root. The cut corn stalks are pulled downward by the stem pulling roller. When the stalks are pulled to a certain extent, the corn cob stalks come into contact with the ear picking plates. The gap between the two ear picking plates is used to allow the stalks to pass through. The ear stalks of the ears are pulled off by the ear picking plates, thereby completing the ear picking operation. The ears separated from the stalks are conveyed to the end of the cutting table along the ear pulling chain, and are gathered by the dragon and enter the peeling channel.

[0003] During the ear-picking operation on the header, the distance between the two ear-picking plates is a key factor affecting the ear-picking effect. If the distance is too close, the corn stalks will not be able to slide smoothly between the two ear-picking plates. Moreover, when the corn stalks slide between the two ear-picking plates, the two ear-picking plates that are too close to each other can easily cause the corn stalks to be pulled apart by the stalk-pulling rollers, causing the corn stalks to enter the peeling channel and block the equipment. Two ear picking boards that are too far apart are also not conducive to the corn ear picking operation. It is easy for the kernels near the ear stalk of the corn ear to fall off or be damaged by the action of the ear picking boards, or some small ears of corn are chopped and returned to the field along with the stalks. In order to meet the need to adjust the gap of the ear picking boards when switching the working environment, the mounting holes of the ear picking boards are usually designed to be oblong. When the gap of the ear picking boards needs to be adjusted, the screws fixing the ear picking boards are loosened, the position of the ear picking boards is manually adjusted, and then the screws are tightened. However, this method of adjusting the ear picking boards is relatively cumbersome, and it is easy to affect the operating efficiency of the harvester and delay the harvesting time. In addition, the position of each ear picking board cannot be accurately adjusted, which leads to inconsistent gaps between the two ear picking boards, inconsistent gaps between different ear picking boards, and other consequences, affecting the corn harvesting effect.

[0004] A Chinese invention patent application numbered 201510188996.8 discloses a corn harvesting platform with self-adjusting ear-picking plate gaps, comprising a frame, a gearbox, a stem-pulling roller assembly, an ear-picking plate assembly, and a straw chain assembly. The frame comprises a main frame, a chain guard plate, and a chain guard plate support plate. The stem-pulling roller assembly comprises a stem-pulling knife roller, a ball head, a connecting fixing sleeve, and an inlet cone. The ear-picking plate assembly comprises an ear-picking plate, a rotating shaft, an ear-picking plate gap adjustment device, and a spring adjustment device. The straw chain assembly comprises a straw chain, a driving sprocket, a driven sprocket, and a driven sprocket tensioning adjustment device. However, this corn harvesting platform with self-adjusting ear-picking plate gaps can only adjust a single ear-picking plate structure, and cannot uniformly adjust the positions of multiple sets of ear-picking plate structures. The adjustment method is relatively complex, requiring the coordination of multiple sets of components to achieve ear-picking plate gap adjustment, resulting in high cost. Utility Model Content
