The configuration and operation of the seed film laying apparatus 100 according to an exemplary embodiment of the present invention will be first described herein below, and then the method for laying a rice seed in a way of dibbling and bio-distribution using the seed film laying apparatus 100 will be described. First,
As illustrated in
The seed film laying apparatus 100 according to an exemplary embodiment of the present invention, as illustrated in
The seed film 2 used in the seed film laying apparatus 100 according to an exemplary embodiment of the present invention is not limited to its specific material or type as far as such a seed film 2 could be biologically degradable.
The seed film 2 is wound around the roller type seed film holding unit 20. The wound seed film 2 may be rotated and unrolled by a rotation unit configured to rotate the seed film holding unit 20 and may be spread over the soil of the rice paddy. A holding unit support 21 is disposed between the seed film holding unit 20 and the top of the frame for interconnecting the seed film holding unit 20 and the frame.
In addition, the seed film holding unit 20 rotates by the rotation unit, and the seed film 2 wound around the seed film holding unit 20 is unrolled, and the seed film 2 is spread over the soil of the rice paddy, and the spread seed film 2 is pressed by the seed film pressing unit 40 (S20).
Next, the seed film fixing unit 50 presses the ends of each of both sides of the pressed seed film 2, and the both sides of the seed film 2 are buried under the soil, and the seed film 2 is spread over the soil of the rice field and is fixedly laid (S30). The above-described procedures are automatically and continuously performed while the agriculture machine 1 moves forwards. In addition, when the laying procedure of the seed film 2 is finished, which will be described later, the cutter unit provided at the seed film laying apparatus 100 starts and automatically cuts the seed film 2.
The operation and function of each component of the seed film laying apparatus 100 will be described step by step in detail.
As illustrated in
As illustrated in
The seed film laying apparatus 100 according to an exemplary embodiment of the present invention further includes an elastic member 32 for balancing the left and right sides of the leveling board 30.
In addition, the seed film laying apparatus 100 according to an exemplary embodiment of the present invention, as illustrated in
As illustrated in
In addition, the seed film laying apparatus 100 according to an exemplary embodiment of the present invention includes a seed film fixing unit 50.
Referring to
The fixing unit support 51, as illustrated in
In addition, the seed film laying apparatus 100 according to an exemplary embodiment of the present invention may further include an absorber unit 57 disposed between the end portion of the top of the top support 52 and one side of the bottom support 53. Since the absorber unit 57 is provided, it is possible to adjust the depth where the seed film fixing unit 50 is buried under soil based on the height and hardness of the soil of the rice paddy when fixing both ends of the seed film at the soil of the rice paddy while absorbing and alleviating the impacts generating due to any changes in the height and hardness of the soil of the rice paddy.
In addition, a cutter unit may be provided at the seed film fixing unit 50 of the seed film laying apparatus 100 according to an exemplary embodiment of the present invention.
The cutter unit according to an exemplary embodiment of the present invention includes a rotation member 62 of which an intermediate portion is secured through a second hinge 65 to an end portion of the bottom of the bottom support 53, a cutter 61 installed at one side of the rotation member 62, a cutter operation unit 64 secured to one end of the rotation member 62, and a spring member 63 disposed between the other end of the rotation member 62 and the bottom support 53.
Therefore, in a state where the cutter operation unit 64 is not driven (namely, when the laying work of the seed film 2 is going on), the cutter 61 attached to the rotation member 62 has been already moved upward by means of the elastic force of the spring member 63. When it needs to cut the seed film 2 after the laying work of the seed film 2 is finished, the cutter operation unit 64 starts, and the rotation member 62 rotates in the clockwise direction about the direction as illustrated in
In addition, a plurality of pressing wheels 56 may be further provided at the seed film fixing unit 50 of the seed film laying apparatus 100 according to an exemplary embodiment of the present invention. As illustrated in
