Description

Onion Transplanting device < RTI ID = 0.0 >

The present invention relates to an onion implanter, and more particularly, to a transplanting apparatus having a simpler structure and capable of precisely transferring an onion seedling cultivated at a constant size with a minimum force to a cultivation land.

It is common to grow onions by growing them in a certain size after sprouting from the tray and then transplanting them again into the cultivation area. When onion seedlings are transplanted to the field, they usually use a pair of implant cups. For example, such a graft cup is supported to be movable up and down, and its lower end has a sharp conical shape. Such a graft cup is configured to receive the transferred onion seedlings and then descend to dig a certain depth of the ground surface of the cultivation land and raise the onion down.

For example, according to the onion implant machine proposed in Korean Utility Model Registration No. 20-0343103, the graft cup has an inverted conical shape as a whole, and two members are combined on both sides to form one graft cup. Such a graft cup is opened and closed while the lower end of the graft is rotated around the upper end. In addition to the onion grafting apparatus, most grafting apparatuses that transfer the seedlings to the cultivation plant use the graft cup structure.

When such a graft cup is used, both sides of the graft cup constituted by a pair are rotated around the support shaft so that the seedlings inside are transferred to the growing site. In the above-mentioned conventional technique, the graft cup is composed of a front graft blade and a rear graft blade to form an inverted conical shape as a whole, and the front graft blade and the rear graft blade can be rotated outward .

However, according to this conventional structure, two power transmission structures are provided so that two graft blades constituting the graft cup can be opened to the outside, and in each power transmission structure, most of the links from the driving source to the graft cup And the power transmission system using the power transmission system is configured to have the structure of a very complicated disadvantage can be said. Structural complexity is not only disadvantageous in terms of the production of the product, but also causes a disadvantage in terms of maintenance. This structural complexity means that there is a large loss due to friction during the power transmission process, which means that there is a disadvantage of power loss in opening and closing the graft cup.

It is an object of the present invention to provide a graft cup opening / closing device having a simple structure in the process of power transmission from a driving source to a graft cup and simplifying its own structure for opening and closing the graft cup.

It is another object of the present invention to provide an opening and closing apparatus capable of minimizing power loss from a driving source to a graft cup opening / closing apparatus.

It is still another object of the present invention to provide an opening and closing apparatus which is capable of easily deforming or changing the structure of a design of an onion implanter by using wire as much as possible, .

In order to achieve the above object, an apparatus for opening and closing a transfer cup of an onion implanter according to the present invention is an apparatus for opening and closing a transfer cup of an onion implanter having an engine and a transmission supported by a frame (F) A cam; A cam follower elastically supported so that one side thereof is in close contact with the operation cam; A wire having one end connected to the other side of the cam follower and being pulled toward or away from the cam follower side in accordance with rotation of the actuating cam; A first driving plate rotatably supported around a support shaft in a hopper frame and rotatable about a support axis by a predetermined interval by the movement of the wire; A second driving plate rotatably connected to the hopper frame around a support shaft; A first graft cup and a second graft cup connected to the lower ends of the first driving plate and the second driving plate, respectively; An interlocking means for interlocking the first driving plate and the second driving plate to simultaneously open the first transplanting cup and the second transplanting cup; And a spring connected between the first driving plate and the second driving plate for supporting the first graft cup and the second graft cup in directions of closing each other.

According to another embodiment of the present invention, the driving plate and the driven plate, and the first and second graft cups are each composed of a plurality of longitudinally arranged members. At this time, the wire is configured such that the opening and closing shafts connecting the upper ends of the plurality of driving plates are connected to the other end, and the opening and closing shafts are pulled to rotate the driving plate about the supporting shaft so that the first and second graft cups are opened have.

According to the embodiment of the interlocking means of the present invention, the projecting portion formed on the drive plate on the side contacting the driven plate and the concave portion formed on the driven plate on the side in contact with the drive plate, to which the projecting portion is engaged, The projecting portion pushes the concave portion and the follower plate is pivoted about the support shaft so that the first and second graft cups are simultaneously opened.

According to the structure of the present invention as described above, it can be seen that the cam, the cam follower, and the wire are used to generate the driving force for opening and closing the graft cup. Such a cam actually has a small configuration, and the wire can freely adjust its path in the internal configuration of the onion implanter. Therefore, it is expected that the overall design of the onion implanter is highly flexible and the configuration can be easily changed.

According to the present invention, when the wire rotates the drive plate in a predetermined direction in one direction, it can be seen that the driven plate is also interlocked with the driven plate to open the graft cup. Therefore, it can be seen that the graft cup can be opened and closed with a remarkably simple structure as compared with the structure for driving the first graft cup and the second graft cup, respectively. Therefore, it can be seen that there is a merit advantageous in terms of a simple construction as a whole and manufacturing and maintenance due to this.

Further, according to the present invention, since the wire is used as the power transmission medium, it is expected that the onion implanter can be opened and closed with the minimum force by solving the problems such as frictional force generated in the conventional link and the like.

1 is an overall side view of an onion implanter of the present invention.
2 is an exemplary perspective view illustrating the implanting device of the present invention.
3 is an exemplary side view for explaining the opening and closing structure of the implanting device of the present invention.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. Fig. 1 is a side view of a part related to the opening / closing apparatus of the present invention, among the whole onion implanter of the present invention. Such an onion implanter includes an engine (not shown) as a drive source and a transmission 2 for changing to an appropriate number of revolutions that requires an output from such an engine. That is, it can be understood that the onion implanter of the present invention is capable of running using an engine.

The above-described engine and transmission 2 are supported by the frame F. Then, the output from the engine is transmitted to the transmission 2, and the output shaft 4 is rotated. The output shaft 4 is provided with an operation cam 10, which is the same as that known in the art, in that the operation cam 10 has a portion having a different radial length. One side of the cam follower 12 is in contact with the operation cam 10. The cam follower 12 is in contact with the operation cam 10 at one side with respect to the center shaft 12a supported by the frame.

Therefore, the cam follower 12 performs the arc motion in which the cam follower 12 repeats a predetermined interval around the central axis 12a by the rotation operation of the operation cam 10. A wire 14 is connected to one side of the cam follower 12. Therefore, according to the repetitive arc motion of the cam follower 12, the wire 14 is pulled to a certain length in the direction of the cam follower 12 and then repeatedly released again. That is, since the cam follower 12 is resiliently supported to be in close contact with the cam follower 12, when the operation cam 10 rotates in a state where one side is in close contact with the operation cam 10, And is pulled toward the follower (12) side, and is repeatedly released.

In the present invention, by using the wire 14 as described above, compared with the structure using a link or a lever as in the prior art, more convenient design is possible and operation can be more conveniently performed. In FIG. 1, the wire 14 is illustratively supported by the frame F, but it is needless to say that the supporting structure of the wire 14 may be variously modified.

The other end of the wire 14 is connected to the wire hook 26 for opening and closing the graft cup 30 as described later. As shown in Fig. 2, the implanting device 20 according to the present invention is provided at the rear lower end of the onion implanter of the present invention. The transplanting apparatus 20 includes a plurality of hoppers 21 for receiving onion seedlings supplied while being dropped from the upper portion and a hopper frame 22 for supporting the hopper 21 and the implantation cup 30 described below .

Then, the hopper frame 22 of the grafting device 20 is planted with onion seedlings in the cultivation field while repeating the upward and downward movement by the action link 27. Here, the structure of the operating link 27 is substantially not directly related to the present invention, and a known structure can be used, so that a detailed description and a detailed description thereof will be omitted. The up and down movement of the hopper frame 22 is guided by the pair of sliding rods 23.

The hopper 21 is linearly arranged on the hopper frame 22 and moves up and down by the link mechanism 27 (not shown in detail) provided on the onion implanter, as described above. Then, the hopper 21 receives the onion seedlings falling from above and supplies it to the implantation cup 30 to be described later. In the hopper frame 22, a plurality of graft cups 30 are provided at the lower portion of the hopper 21. An opening / closing shaft 24 is installed at one side of the horror frame 22 in the same longitudinal direction as the transplanting cup 30 is disposed.

2 and 3, the structure of the implantation cup 30 and its opening / closing structure will be described below. The opening and closing shaft 24 is connected to the upper end portion 32aa of the driving plate 32a. The driving plate 32a is rotatably supported about the support shaft 32c with respect to the hopper frame 22. A driven plate 32b driven by the driving plate 32a is rotatably connected to the hopper frame 22 around a support shaft 34c.

The transplanting cup 30 can be said to plant the onion seedlings substantially in the ground of the cultivation land. The transplanting cup 30 has an inverted conical shape as a whole and is composed of a first transplanting cup 32 and a second transplanting cup 34. That is, the first graft cup 32 and the second graft cup 34 have a shape corresponding to a vertically half of a conical shape, and when they are combined, they have a semi-conical shape as a whole. When they are opened, as shown in Fig. 3, the lower end is opened, and the onion seedlings inside the seedlings fall into the ground.

As described above, the first graft cup 32 and the second graft cup 34 constituting the graft cup 30 are connected to the drive plate 32a and the driven plate 34b, respectively. Therefore, when the driving plate 32a and the driven plate 34b are respectively pivoted outward around the support shafts 32c and 34c supporting them, the lower end of the graft cup 30 is opened Reference). The first and second grafting cups 32 and 34 are elastically supported substantially in a direction to close the first and second grafting cups 32 and 34.

For example, at the lower positions of the support shafts 32c and 34c, a spring S for pulling the drive plates 32a and 34a in directions close to each other is provided. The driving plate 32a and the driven plate 34a are urged toward each other by the force of the spring S so that the first and second graft cups 34 and 34 Can be kept closed with each other.

The driving plate 32a and the driven plate 34a are configured to be interlocked with each other. That is, in the present invention, when the above-described wire 14 is opened to the outside of the drive plate 32a, the follower plate 34a is also opened to the outside in conjunction with this. The drive plate 32a is formed with a protrusion 32b having an arc shape at an end thereof and the driven plate 34a is provided with the protrusion 32a, 32b are joined to each other by a recessed portion 34b having an arc-shaped inside end. It can be seen from FIG. 3 that the protruding portion 32b and the recessed portion 34b are kept in contact with each other.

Hereinafter, the operation of the apparatus for opening / closing the graft cup according to the present invention will be described. The onion implants of the present invention allow the onion seedlings to be transplanted into the ground of the cultivation ground while traveling. Since the onion seedling is moved in the up and down direction and the onion seedling is planted in the ground, it is not directly related to the present invention, so a detailed description thereof will be omitted.

When the onion implanter is driven, the operating cam 10 is rotated by the output shaft 4 of the transmission 2. The cam follower 12, one side of which is in close contact with the operation cam 20, is repeatedly moved circularly around its central axis 12a by the rotation of the operation cam 20. Therefore, the wire 14, one end of which is connected to one side of the cam follower 12, is pulled by the cam follower 12 and is repeatedly released to the opposite side.

The other end of the wire 14 is hooked to the wire hook 26 shown in Fig. Therefore, when pulled by the operation cam 10 and the cam follower 12, the wire hook 26 is pulled in the direction shown by the arrow C. Since the wire hook 26 is connected to the opening and closing shaft 24, the opening and closing shaft 24 is pulled substantially in the direction of arrow C.

When the opening and closing shaft 24 is pulled, the driving plate 32a provided at the lower portion is rotated clockwise about the supporting shaft 32c. At the same time, the driven plate 32a having the concave portion 34b engaged with the projecting portion 32b of the driving plate 32 also rotates counterclockwise about the support shaft 34c. That is, the driven plate 34 rotates in the counterclockwise direction due to the rotation of the projecting portion 32b of the drive plate 32a in contact with the concave portion 34b of the driven plate 34. [

The rotation of the drive plate 32a in the clockwise direction (see the arrow A direction) and the rotation of the driven plate 34a in the counterclockwise direction (see the arrow B direction) occur substantially simultaneously. Therefore, the first and second graft cups 32 and 34, which are coupled to the lower ends of the driving plate 32a and the driven plate 34a, respectively, are opened at the lower end as shown in the figure. The opening of the lower end of the graft cup 30 as described above means that the onion seedlings supplied through the hopper 21 can fall downward.

The lower end of the graft cup 30 is opened as described above. In fact, the graft cup 30 is lowered to a certain depth into the ground of the cultivation ground. And, after the graft cup 30 is opened and the onion seedlings are dropped in this way, the graft cup 30 will rise like the hopper frame 22. At this time, as the operation cam 10 rotates, the cam follower 12 in contact with the rotation causes the wire 14 to be pulled out.

The drive plate 32 and the driven plate 34 are brought close to each other by the resilient restoring force of the spring S when the force of the wire 14 pulling the opening and closing shaft 24 through the wire hook 26 is removed, . That is, the driving plate 32 is rotated in the counterclockwise direction and the driven plate 34 is rotated in the clockwise direction, so that the first and second graft cups 32 and 34 are closed.

Since the above-described operation is repeated with a predetermined period by the rotation of the operation cam 10, the graft cup 30 substantially repeats the opening and closing operation periodically. Therefore, it can be seen that the implant cup 30 can drop the onion seedlings downward with a certain period of time, such as running the onion seedlings.

As described above, according to the present invention, it is understood that one of the driving plates is driven by wires and the driven plate is interlocked with the driving plate while using the operation cam and wire. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
