Description

An elastic splitting device for millet combine harvester

Technical field

The invention belongs to the technical field of agricultural machinery and equipment, and specifically relates to an elastic grain dividing device of a millet combine harvester.

Background technique

The harvester is widely used in combine harvesters. Its function is to separate the harvested crops from the crops to be harvested, and at the same time guide the harvested crops into the header.

When the millet matures, the ears bend and droop, with a large gap in the position of the ear layers. The ears grow in no direction, causing the ears to intersect and the stems to become entangled. When harvested by a combine harvester, the ears and stems are entangled and difficult to separate. It is easy to cause ear loss from the header, and when the existing millet combine harvester is dividing the grain, the grain divider is inserted between the two ridges of millet, and the entangled millet is forcibly separated while advancing forward. The ears of grain will be torn off, causing greater losses.

The traditional grain divider is as described in the application number CN201420532091.9 "A new type of combine harvester grain divider structure". The grain divider structure includes a grain divider tip, an inner grain dividing rod, an outer grain dividing rod, and an inner grain dividing support. The rod, external grain dividing support rod, two upper support rods, two lower support rods, lower support reinforcement rod, and grain divider fixed plate are all rigidly connected and fixed together to form a front tip that is wider at the back and a lower tip that is wider at the top. The rigid structure of the machine forcibly separates the intertwined grains while pushing forward, which can easily break the ears of grains, causing the ears of grains to fall off and prevent harvesting, resulting in a certain amount of waste and economic losses.

Detailed ways:

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, an elastic grain dividing device for a millet combine harvester includes a grain divider main body 2 installed on both sides of the millet combine harvester cutting frame through a connecting seat 1. The grain divider main body 2 is forward The front end of the main body 2 of the grain divider is detachably equipped with a grain divider tip 3, which is small and tapered, and is convenient for maintenance and replacement, and can extend the service life. The surface of the grain divider tip 3 is smooth and arc-shaped; the upper end of the grain divider main body 2 is A support 4 is provided, a top grain dividing plate 5 is provided above the support 4, and side grain dividing plates 6 are provided on both sides. The rear is large, and the top grain dividing plate 5 is hinged with the side grain dividing plate 6. The top grain dividing plate 5 is connected to the support 4 through the push rod 7, and the side grain dividing plate 6 is connected to the support 4 through the side push rod 7. Push The rod 7 and the side push rod 8 can move along the axial direction. The push rod 7 and the side push rod 8 are covered with springs 9 to help the push rod 7 and the side push rod 8 reset. The inner end of the push rod 7 is provided with a triangular slope. Block 10, the two inclined surfaces of the inclined block 10 are in contact with the inner end of the side push rod 8, so that when the push rod 7 moves downward, the side push rod 8 is pushed out. Since the top grain dividing plate 5 and the side grain dividing plate 6 are hinged , when the top grain dividing plate 5 comes into contact with the intertwined millet stalks, it moves downward under pressure, causing the top push rod 7 to move downward and pushing the side push rod 8 outward, causing the side grain dividing plate 6 to rotate outward and open. The side grain dividing plate 6 separates the intertwined millet stalks. After separation, the top grain dividing plate 5 and the side grain dividing plate 6 reset under the action of the spring 9 to prepare for the next grain dividing.

Further, the main body 2 of the grain divider is connected to the connection base through the angle adjustment device 11. The angle adjustment device 11 includes a cylinder. The main body 2 of the grain divider is hingedly connected to the connection base 1. One end of the cylinder is connected to the main body 2 of the grain divider, and the other end of the cylinder is connected to the connection base 1. The angle adjustment device 11 can also adopt a hydraulic cylinder or multi-link structure.

Furthermore, the main body 2 of the grain divider is also provided with a vibration device 12, so that the top grain dividing plate 5 and the side grain dividing plate 6 are driven by the vibration device 12 to open and close rhythmically, even if the millet stalks are intertwined Without pressing down the top grain divider plate 5, the side grain divider plates 6 will also open and close to separate the millet stalks, and gradually separate them step by step, instead of directly pulling them apart at once with the traditional grain divider.

Further, the inclined block 10 adopts an isosceles triangle structure, and two equal sides are in contact with the inner end of the side push rod 8, so that when the push rod 7 moves downward, the side push rod 8 is pushed out simultaneously.

Furthermore, the top grain dividing plate 5 and the side grain dividing plate 6 have an outwardly convex arc shape in cross section.

Further, as shown in Figure 4, the upper surfaces of the longitudinal sections of the top grain dividing plate 5 and the side grain dividing plates 6 adopt a sinusoidal structure, so that the intertwined millet stalks are aligned with each other relative to the top grain dividing plate 5 and the side grain dividing plate 6. When the grain board 6 is moved backward and separated, it is separated by shaking and shaking, instead of being separated directly, so that the separation effect is better and it is less likely to tear the ears of grain.

Further, an inner grain dividing rod 13 and an outer grain dividing rod 14 are respectively provided on both sides of the main body 2 of the grain divider. The outer grain dividing rod 14 pushes the uncut grain away from the grain dividing device, and the inner grain dividing rod 13 pushes the uncut grain away from the grain dividing device. The millet plants are pushed into the header, closer to the reel, and easily moved into the header.

Further, the outer grain dividing pole 14 and the inner grain dividing pole 13 are low in front and high in rear, and tilt upward by 5-15°.

Further, the top grain dividing plate 5 and the side grain dividing plate 6 are hinged through hinges 15 .

The specific working process is as follows. When the machine is moving forward, when the top splitting plate 5 on the grain dividing device comes into contact with the intertwined millet stalks, the intertwined stalks make the top splitting plate 5 move downward, and the pushing rod 7 Move downward and push out the side push rod 8 at the same time, causing the side grain dividing plates 6 to rotate outward and open. The side grain dividing plates 6 separate the intertwined millet stalks. Under the action of the grain dividing rod 13, the outer grain dividing rod 14 pushes the uncut millet away from the grain dividing device, and the inner grain dividing rod 13 pushes the millet plants to be cut into the cutting table, closer to the reel and easy to be dialed in. In the header, with the support of the reel, the bottom is cut by the reciprocating cutter, which can effectively alleviate the problem of ear falling due to pulling of the grain dividing. After the grain dividing is completed, the top grain dividing plate 5 and the side grain dividing plate 6 are in the spring Under the influence of 9, it returns to its original state and continues to divide the crops.
