Description

Technical Field

[0001] The utility model relates to an ear picking device for a fresh corn harvester, and more particularly to a fresh corn ear picking device. Background Art

[0002] Fresh corn is highly nutritious, with the contents of its protein, sugar and other components far exceeding those of ordinary corn, and containing various elements such as vitamins and minerals. It has a sweet taste and excellent quality. Fresh corn can play a certain preventive effect on cancers, diabetes, etc., can reduce blood pressure and blood lipids, and has health preservation and maintenance effects.

[0003] At present, ear picking plates are widely used on corn harvesters. Due to the fresh, crispy and tender characteristics of fresh corn, the kernels at the root of the corn are easily squeezed out of water when the ear picking plate picks ears, resulting in a high kernel breakage rate of the corn. There are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve it. Summary of the Invention

[0004] The purpose of the utility model is to provide an ear picking device for a fresh corn harvester. The ear picking device picks fresh corn by the relative rotation of the stem pulling rollers, pulling down the fresh corn stalks and cooperating with the forward movement of the ear picking plate and the unit. The device can increase the contact area between the fresh corn ear and the ear picking plate, thereby reducing the impact received when the fresh corn ear collides with the ear picking plate, realizing the reduction of the kernel breakage rate of the fresh corn, reducing the damage to the corn ear, and ensuring the integrity of the fresh corn ear.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: An ear picking device for a fresh corn harvester, including an ear picking plate, stem pulling rollers, and a fixing frame; characterized in that: the side end of the ear picking plate is installed on the fixing frame, and symmetrically arranged stem pulling rollers are provided at the lower end of the ear picking plate; the ear picking plate includes a horizontal part and an arc part, the arc part is recessed downward, one section of the arc part is connected to the horizontal part and the other end is an arc and integrally formed, and at the same time a triangular cut angle with the same angle is provided on one side of the horizontal part and the arc part of the ear picking plate; there are gaps and angles between the ear picking plates, so that the gaps between the ear picking plates are wider at the front and narrower at the rear; on the stem pulling rollers, a plurality of stem pulling roller blades are provided along the circumferential direction thereof, making the whole stem pulling rollers present an inverted trapezoid shape that is thinner at the front and thicker at the rear.

[0006] The beneficial effects of the utility model: The contact part of the ear picking plate provided by the utility model with the fresh corn ear is the arc part, and the arc part is recessed downward, which can increase the contact area between the fresh corn ear and the ear picking plate, reduce the impact received when the fresh corn ear collides with the ear picking plate, prevent the kernels at the bottom of the fresh corn ear from being squeezed out of water, greatly reduce the kernel breakage rate at the root of the fresh corn ear, reduce the damage to the fresh corn, ensure the integrity of the fresh corn ear, and can promote the increase of agricultural production and income.

[0011] For a clearer understanding of the technical features, objectives, and effects of the present invention, the following further description is made with reference to the accompanying drawings: As Figure 1 shown, an ear-picking device for a fresh corn harvester includes an ear-picking plate 1, a stem-pulling roller 2, and a fixed frame 3. The fixed frame 3 is arranged on the fresh corn harvester; As Figure 2 shown, the ear-picking plate 1 is divided into an arc portion and a horizontal portion. The arc portion is a downwardly concave arc. One side of the arc portion is connected to the horizontal portion, and the other side is an arc. The arc portion and the horizontal portion are integrally formed. The side surfaces of the arc portion and the horizontal portion of the ear-picking plate 1 are mounted on the fixed frame 3. There is a triangular cut on the other side, and there are gaps and angles between the two ear-picking plates.

[0012] Working Principle: As Figure 3As shown in the figure, the entire ear picking device is fixed on the fresh corn harvester. The power on the harvester is transmitted to the stalk pulling rollers 2. The two stalk pulling rollers 2 rotate relatively inward simultaneously, and at the same time, cooperate with the forward movement of the machine tool, so that the fresh corn stalks enter the gap 2 between the two ear picking plates 1 from the incision at the front end of the ear picking plate 1. If there are any toppled fresh corn stalks, they will be righted by the spiral ribs at the front end of the stalk pulling rollers 2, and cooperate with the triangular incision at the front end of the ear picking plate 1 to guide the fresh corn stalks into the gap between the two ear picking plates 1. Since the stalks of fresh corn become thinner from the root, the diameter of the stalks at the root is larger than that at the top, so there is a gap for ear picking and an angle to prevent the corn stalks from being blocked between the two ear picking plates 1, making the gap between the ear picking plates 1 wider at the front and narrower at the back. At the same time, in order to prevent the stalk pulling rollers 2 from being blocked or damaging the corn stalks, multiple stalk pulling roller blades are arranged on and around the stalk pulling rollers 2, and the stalk pulling rollers 2 are in an inverted trapezoid shape that is thinner at the front and thicker at the back. At this time, the relative rotation of the stalk pulling rollers 2 gives a force to the corn stalks to make the corn stalks move backward and downward. When the fresh corn stalks move to the point where the corn ear contacts the ear picking plate 1, since the arc part of the ear picking plate 1 is a downward concave arc, it can increase the contact area between the corn ear and the ear picking plate 1, and can reduce the impact received by the corn ear when it contacts the ear picking plate 1, so as to achieve the purpose of reducing the breakage rate of fresh corn kernels. At the same time, because the fresh corn ear is thicker than the corn stalk, the bottom of the fresh corn ear will be stuck above the gap between the two ear picking plates 1, and the corn stalk continues to be pulled downward, resulting in the fresh corn ear falling off from the corn stalk and completing the ear picking operation.

[0013] The above is an example of the best implementation mode of the present invention. The parts not described in detail are all common knowledge of those skilled in the art. The protection scope of the present invention shall be subject to the content of the claims, and any equivalent transformation based on the technical inspiration of the present invention is also within the protection scope of the present invention.
