Corn harvester

[0016] The corn harvester involved in this embodiment is a machine capable of harvesting corn ears and collecting straw. Mainly include crop divider (function: to introduce the corn stalk branches into the machine), cutting knife (function: cut off the corn stalk), ear picking roller (function: separate the ear of corn from the stalk), and straw collector (function: Collect the straw after picking into a pile), straw conveying mechanism (function: transfer the straw after picking to the straw collector) and corn ear collection trough (function: collect corn ears) and other components.

[0017] The technical solution of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, the corn harvester involved in this embodiment includes a frame 1, a side of the frame 1 is installed with a number of component croppers 2, each group of the crop divider 2 is installed with a cutting knife 4, the There are several pairs of picking rollers 3 above the frame 1, and each pair of picking rollers 3 is inclined to the ground. There is a gap between two adjacent rollers of each pair of picking rollers 3, and each pair of picking rollers 3 are adjacent to each other. The gap between the two rollers is larger than the diameter of the corn stalk and smaller than the diameter of the ear of corn. Here, the diameter of the corn stalk and the diameter of the ear of corn can be obtained by taking the average diameter of the corn stalk and the ear of corn in a certain area due to individual differences in individual crops. Each group of straws 2 is located between two adjacent pairs of picking rollers 3, and each group of straws 2 is located at the lower end of the picking rollers 3 and the ground. A corn ear collecting trough 5 is installed on the frame 1, and the corn ear collecting trough 5 is located directly below the lower end of the ear picking roller 3 and the ground. A conveyor belt 6 is installed under the ear picking roller 3, and the conveyor belt 6 transports the corn stalks falling under the ear picking roller 3 to a straw collector.

[0019] Such as Figure 5 As shown, the straw collector includes a fixed plate 7, a movable plate 8, an active cam 9, a connecting rod 10, a fixed rod 11, and a transition rod 12. The fixed plate 7 is fixedly installed on the frame 1 obliquely. The plate 8 is hinged to the fixed plate 7, the movable plate 8 is rigidly fixed with a force transmission rod 13, the force transmission rod 13 is hinged to one end of the transition rod 12, and the other end of the transition rod 12 is connected to the One end of the connecting rod 10 is hinged, the other end of the connecting rod 10 is located below the active cam 9, one end of the fixing rod 11 is rigidly fixed to the frame 1, and the other end is hinged to the connecting rod 10. The active cam 9 is installed on the frame 1.

[0020] The action mechanism of this embodiment is: the corn stalks are cut by the cutting knife after branching through the crop divider, and then enter the ear picking roller. Since the diameter of the ear of corn is larger than the corn stalk, the distance between the ear picking rollers is smaller than the diameter of the ear of corn Therefore, the ear picking roller only allows corn stalks to pass through, and the ears of corn are on top of the ear picking rollers. Because the ear picking rollers are inclined, the ears of corn will slide down into the ears of corn collection trough for easy collection. The corn stalks falling under the ear picking roller fall onto the conveyor belt, and the conveyor belt drives the corn stalks to the straw collector, which can be opened periodically. When the movable plate and the fixed plate are in a V shape, the corn stalks are accumulated in the straw collector. When the movable plate on the straw collector hinges along the fixed plate under the action of the active cam, the straw collector is opened and the straw is collected The corn stalks collected in the container are dumped in piles to the ground to facilitate subsequent manual collection.

[0021] The above examples are only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the industry should understand that all modifications or equivalent substitutions made without departing from the essence of the present invention should fall within the protection scope of the present invention.
