Description

Technology Field

[0001] The present invention relates to a cutting device for a sesame composite harvester, and more specifically, to a cutting device for a sesame composite harvester equipped in a sesame composite harvester that separates and sorts sesame pods and sesame seeds from sesame stalks, and is configured to cut the base of the sesame stalk, transport it, and then smoothly feed it into a threshing unit. Background Technology

[0003] Sesame is an annual herbaceous plant that bears numerous pods at the top of a straight stem, and contains a large number of sesame seeds inside the pods. The edible part is the sesame seed, and to harvest the seeds, the pods must be separated from the stem and the seeds inside the pods must be shaken out.

[0005] The traditional method for harvesting sesame seeds involves laying plastic sheeting or cloth on the ground, laying the sesame stalks on top of it, and then striking the pods of the stalks with a tool called a flail to shake out the seeds. Additionally, impurities such as fallen leaves are separated using a mesh sieve to harvest the sesame seeds.

[0006] However, this traditional method of harvesting sesame seeds requires not only strenuous labor but also long working hours, as workers must manually thresh and separate the seeds. Therefore, it is an extremely difficult task for the labor-scarce rural population.

[0008] Therefore, methods for harvesting sesame using agricultural machinery such as threshing machines are being considered; however, because sesame has long and tough stems, it is difficult to use conventional threshing machines, and there is a problem in that it is very difficult to separate foreign substances when crushing for threshing.

[0010] Accordingly, a sesame multi-purpose threshing machine is being developed that cuts off the base of the sesame stalks and feeds them into the threshing unit; however, this machine has a problem in that long sesame stalks are not properly fed into the threshing unit.

[0012] Meanwhile, Public Patent No. 10-2019-141853 proposes and discloses a power harvester for soybeans and sesame that includes a cart capable of movement equipped with casters, a prime mover mounted on the cart to generate power for transmitting rotational force to the casters, and a cutter mounted to rotate on the lower part of the cart and receiving rotational force from the prime mover. Due to a structure in which the machine moves autonomously when the operator controls only left and right steering, the inconvenience of the operator having to support the machine with their body can be eliminated, and the work load is reduced, allowing for long hours of work and enabling the elderly and infirm to fully participate in the work, thereby improving work efficiency. Furthermore, as the machine moves forward, the cut crops come into close contact with a guide and fall neatly to the side, making subsequent harvesting easier.

[0013] Registered Utility Model No. 20-0370809 comprises: a conveying means for conveying a sesame bundle in an inverted state along a predetermined conveying line; a shattering means installed on the conveying line to apply a lateral impact to the conveyed sesame bundle to shake off the sesame; a separating means installed at the bottom of the conveying line to separate sesame and impurities such as leaves that have fallen from the sesame bundle; side walls installed on both sides along the conveying line to guide sesame and impurities such as leaves that have fallen from the sesame bundle toward the separating means; a second shattering means for shaking off sesame from impurities such as unshattering pods and leaves separated by the separating means; and a conveying means for conveying impurities such as unshattering pods and leaves separated by the separating means to the second shattering means. The sesame bundle is moved in an inverted state while applying an impact to shake off the sesame, and impurities such as unshattering pods and leaves that have fallen together with the sesame are separated from the sesame, and the separated unshattering A stirring impact type sesame hulling machine is proposed and disclosed, which improves sesame hulling efficiency by completely hulling the pods through a secondary hulling and separation process to reliably separate impurities such as sesame and leaves.

[0014] Public Patent No. 10-1998-0007950 proposes and discloses an automatic sesame shedding device in which a series of processes are automatically carried out, in which sesame shedding is automatically conveyed by a conveying means, a shedding process is performed by a shedding means that vibrates up and down, and the shedding is separated and collected by a sorting shedding unit below, thereby achieving excellent workability and productivity. Furthermore, the sorting shedding unit is a vibrating body consisting of a multi-stage mesh that vibrates back and forth to separate sesame seeds, leaves, pods, and foreign substances, and then selects and collects only the seeds through a seed recovery port.

[0015] In Public Utility Model No. 20-2021-0002498, a power harvester for harvesting crops that can maximize work efficiency by cutting the base is proposed and disclosed, comprising: a chassis that is inclined obliquely from the front to the rear, a handle formed for driving connected to the rear of the chassis, a basket that holds the object and is installed at the bottom of the handle and at the rear of the chassis, and a driving wheel located at the bottom of the chassis; a conveyor unit for transporting the object to the container by a belt installed on the upper surface of the chassis; a cutter unit installed at the front of the main body and formed to cut the base of the object; a reel unit for transporting the object cut by the cutter unit to the conveyor unit; a driving unit composed of a motor and a power source for driving the driving wheel, the conveyor unit, the cutter unit, and the reel unit; and a control unit capable of controlling the ON / OFF of the driving unit.

Specific details for implementing the invention

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0034] The terms used in this invention are defined in consideration of their functions within the invention; however, since these may vary depending on the intentions or practices of the user or operator, the definitions of these terms should be interpreted in a sense and concept consistent with the technical details of this invention.

[0036] Figure 1 of the attached drawings is a drawing showing a sesame composite harvester equipped with a cutting device according to the present invention, and Figures 2 to 9 are drawings for explaining a cutting device for a sesame composite harvester according to the invention.

[0038] In the present invention, the cutting device for a sesame composite harvester is installed at the front of the sesame composite harvester. That is, as shown in FIG. 1, the sesame composite harvester comprises a driving unit (30), a main body (20) installed on the upper side of the driving unit (30) and equipped with a threshing unit (21) for separating and sorting sesame from sesame pods, a rotary guide reel (40) installed at the front of the main body (20) to grip sesame stalks, and a cutting device (10) installed at the front of the main body (20).

[0040] And the cutting device (10) includes a reciprocating cutting blade (11), an inclined conveying part (12), a pressure conveying part (13), and an angle adjustment piece (15), as shown in FIGS. 1 and FIGS. 2.

[0041] The reciprocating cutting blade (11) cuts the base of the sesame stalk and is provided at the lower end of the inclined conveying unit (12). The inclined conveying unit (12) transmits the sesame stalk cut by the reciprocating cutting blade (11) to the upper threshing unit (21) via a lower conveyor belt (121) arranged at an angle, and its upper end is rotatably installed in the threshing unit (21).

[0042] The pressure conveying unit (13) pressure conveys the sesame stalks moving along the inclined conveying unit (12) and feeds them into the threshing unit (21), and is rotatably installed on the upper side of the inclined conveying unit (12).

[0043] And the angle adjustment piece (15) is installed in the threshing unit (21) to allow the installation angle of the inclined conveying unit (12) and the pressure conveying unit (13) to be adjusted.

[0045] As shown in FIG. 2, the above-mentioned pressure conveying unit (13) comprises a conveying unit frame (131), an upper conveying belt (132) formed in a triangular shape so as to protrude downward toward the inclined conveying unit (12) and rotated, a plurality of lugs (133) formed in a trapezoidal shape protruding from the outer surface of the upper conveying belt (132) to hold the sesame stalks and arranged along the width direction of the upper conveying belt (132) and arranged at regular intervals along the length direction of the upper conveying belt (132), a first tensioning unit (134) installed on the conveying unit frame (131) to adjust the tension of the longitudinal edge of the upper conveying belt (132), and a second tensioning unit (135) installed on the conveying unit frame (131) to raise and lower the lower edge of the upper conveying belt (132).

[0046] Accordingly, the lug (133) of the upper conveyor belt (131) presses the sesame stalk, so that the sesame stalk is smoothly conveyed along the lower conveyor belt (121) of the inclined conveyor section (12).

[0047] And by using the second tension part (135), the pressure applied to the sesame stalks by the lug (133) can be adjusted, and by using the first tension part (134), the tension of the upper conveyor belt (131) can be maintained uniformly.

[0049] Meanwhile, the lugs (133) are arranged parallel to each other along the length direction of the upper conveyor belt (132) as shown in FIG. 3, in which case the sesame stalks may not be conveyed as they get stuck in the gaps between the lugs (133).

[0050] Accordingly, as shown in FIG. 4, the lugs (133) may be arranged in a zigzag shape by being crossed along the length direction of the upper conveyor belt (132) so that the sesame stalks being conveyed do not get caught.

[0051] As shown in FIG. 5, these lugs (133) pressurize the sesame stalks when transporting them using the lower conveyor belt (121) of the inclined transport unit (12) and the upper transport belt (132) of the pressurized transport unit (13), thereby allowing the sesame stalks to be transported smoothly and fed into the threshing unit (21) of the main body (20).

[0053] And, as shown in FIG. 6, a wing portion (133') formed at an angle along the conveying direction may be connected to the top of the lug (133), and the wing portion (133') is preferably made of a soft material.

[0054] In this way, the reason for connecting the wing portion (133') to the lug (133) is to prevent the lug (133) of the upper conveyor belt (132) from pressing the sesame stalks with excessive pressure when transporting the sesame stalks using the lower conveyor belt (121) of the inclined conveyor portion (12) and the upper conveyor belt (132) of the pressurized conveyor portion (13) as shown in FIG. 7.

[0056] Meanwhile, as shown in FIG. 8, the angle adjustment piece (15) that allows the angle of the pressure transfer part (13) and the inclined transfer part (12) to be adjusted is formed such that a first elongated section (151) with a curved shape is formed at a certain distance from the upper side to adjust the angle of the pressure transfer part (13), and a second elongated section (152) with a curved shape is formed at a certain distance from the lower side to adjust the angle of the inclined transfer part (12).

[0057] Accordingly, as shown in FIG. 9, the angle of the pressure transfer unit (13) can be adjusted and fixed through the first length unit (151), and the angle of the inclined transfer unit (12) can be adjusted and fixed through the second length unit (152).

[0059] Accordingly, the cutting of sesame stalks using the cutting device for the sesame composite harvester of the present invention configured as described above, and the subsequent transfer and feeding of the stalks to the threshing section of the main body, is explained as follows.

[0060] First, the angle of the inclined conveying unit (12) is adjusted and fixed through the second elongated hole (152) formed in the angle adjustment piece (15) of the threshing unit (21) provided in the main body (20) of the sesame complex harvester so that the reciprocating cutting blade (11) is spaced a certain distance from the ground.

[0061] Then, the angle of the pressure transfer unit (13) is adjusted through the first slot (151) formed in the angle adjustment piece (15) to fix the gap between the pressure transfer unit (13) and the inclined transfer unit (11), thereby completing the preparation for the operation.

[0063] When the operation begins, the main body (20) is advanced by the driving unit (30), and while the main body (20) is moving, the upper part of the sesame stalk is gathered using the guide reel (40) and at the same time, the base of the sesame stalk is cut through the reciprocating cutting blade (11).

[0064] The cut sesame stalks are transported to the threshing section (21) of the main body (20) via the lower conveyor belt (121) of the inclined transport section (12).

[0065] Then, the sesame stalks are pressed and transported using the lug (133) of the upper conveyor belt (132) of the pressure conveyor unit (13), and then fed into the threshing unit (21).

[0066] That is, after the sesame stalks are introduced between the pressure conveying section (13) and the inclined conveying section (11), they are pressure-conveyed by the lugs (133) of the upper conveying belt (132) and fed into the threshing section.

[0068] Afterwards, in the threshing section (21), sesame pods and sesame seeds are separated from the sesame stalks, and sesame seeds are separated from the sesame pods.

[0069] And the sesame stalks and impurities are discharged separately, and the sesame seeds are discharged after being sorted in the sorting section within the main body (20).

[0071] The embodiments described above are merely illustrative of preferred embodiments of the present invention and are not strictly limited to such embodiments. Various modifications and variations may be made by those skilled in the art within the technical spirit and scope of the claims of the present invention, and such modifications and variations fall within the technical scope of the present invention.
