Description

Technical Field

[0001] The present invention relates to a technology for producing a seed film by attaching seeds to a biodegradable film while minimizing damage to the seeds using a seed applicator, spreading drip irrigation water and the seed film on agricultural land using a laying machine, and covering the top with soil to fix the seed film to the agricultural ground and sowing seeds. It is a seed film production device for cultivating agricultural crops by utilizing the precision of drip irrigation, the ability to supply water near the roots of crops, and the evaporation suppression function of the biodegradable film, and a seeding system that minimizes wasteful use of water including the same.

Background Art

[0002] Agriculture consumes 70% of the clean water withdrawn worldwide, such as groundwater and river water, and rice cultivation and wheat farming consume 70% of the water consumed in crop cultivation worldwide. Rice and wheat are the staple foods of the largest number of people, and not only the production volume but also the amount of irrigation water consumed per 1 kg of production is enormous. According to the water footprint published by UNESCO, 3000 liters of water are required to produce 1 kg of rice, and 1350 liters of water are required to produce 1 kg of wheat. If the temperature in the atmosphere rises due to global warming, an increase in irrigation water is inevitable. Saudi Arabia, which cultivates wheat in a hot and dry climate, consumes about 2000 liters of water per 1 kg of wheat production, using 50% more irrigation water than the world average. Considering the research findings that the likelihood of severe drought increases 20-fold as climate change intensifies, the need for irrigation water saving technologies is increasing.

[0003] For these reasons, there have been many efforts to save water in the cultivation of wheat and rice. According to the 2011 - 14 research of ICAR - Central Institute of Agricultural Engineering in the Indore region of India, about 310 liters of water were consumed to cultivate 1 kg of wheat using drip irrigation, which represents a 77% reduction compared to the world average water footprint of 1350 liters / kg. Netafim cultivated rice using the drip irrigation method, and not only had a higher yield than existing rice, but also used 70% less water. Drip irrigation is reported to be the most efficient among all irrigation methods, achieving an increase in yield of up to 100% and water savings of up to 40 - 80% (Burney·2009; Lodhi·2014; Kumari·2014).

[0004] However, even when using drip irrigation, it is not possible to prevent evaporation occurring on the farmland, and an irrigation method has emerged that attempts to further suppress the waste of water by mulching the drip irrigation surface with a film. Q Jia (2021) compared the cases of drip irrigation with soil covering and film mulching. When only covering the soil without film mulching, the soil evaporation was 2.4 times higher than when film mulching was used. Also, when drip irrigation is carried out under film mulching, the crop yield and water use efficiency increased by about 20% and 30% respectively compared to non - mulching drip irrigation. (W Zhang·2022). Such a drip irrigation method under film mulching is widely applied in the cultivation of cotton in the Xinjiang region of China. However, this method has not been applied in regions outside Xinjiang of China or to other crops other than cotton in Xinjiang, and the main reasons are the large amount of labor required to install drip irrigation under the film while mulching the film, and the serious environmental pollution problem caused by residual plastic films after agriculture.

[0012] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and can be embodied in various different forms. Merely, these embodiments are provided to complete the disclosure of the present invention and to fully inform those skilled in the art of the scope of the invention. The same reference numerals in the drawings denote the same elements.

[0013] When adding reference numerals to the components of each drawing, it should be noted that for the same components, as much as possible, the same reference numerals are used even if they are shown on other drawings. Further, in describing the present invention, when it is determined that a detailed description of related known configurations or functions may obscure the gist of the present invention, the detailed description thereof is omitted.

[0014] Hereinafter, with reference to the drawings, a device for supplying a seed film is described, in which an environmentally friendly adhesive is applied through a slit adhesion part to a mulching film, which is a plant-derived biodegradable film supplied according to an embodiment of the present invention, and the seed is supplied using a seed attachment part in a state where damage to the seed is minimized.

[0015] A seed film supply device according to an embodiment of the present invention includes a slit adhesion part 10 that enables the formation of a germination gap for the attachment of seeds on a biodegradable film 1 supplied from a mulching film supply part 2, a seed supply part 50 that enables the input of seeds onto the germination gap formed through the slit adhesion part 10, and a mulching film laying part 60 that spreads the biodegradable film with seeds attached thereon and covers the biodegradable film 1 with soil scattered by a rotary tiller 70 which is a soil scattering part. In the present invention, a device including the slit adhesion part 10 and the seed supply part 50 is a seed biodegradable film production device.

[0016] A germination gap is formed in the biodegradable film 1 supplied from the mulching film supply unit 2 through the slit adhesion part 10. After supplying the adhesive, the mulching film is wound around the mulching film recovery unit 3 in a state where seeds are supplied onto the germination gap through the seed supply unit 50. During the above process, the plurality of rotating rollers 4 enable smooth transfer of the mulching film.

[0017] Thereafter, a drip hose 62 is buried through a plurality of roller members 64 and 65 under the mulching film to which seeds are supplied through the mulching film laying unit 60, fertilizer is supplied to the mulching film through the fertilizer applicator 80, and the soil is dispersed through the rotary tiller 70.

[0018] The present invention produces a mulching film based on a biodegradable film derived from plants. It is desirable that the adhesive used for the mulching film is environmentally friendly and does not generate VOCs.

[0019] The slit adhesion part 10 includes a slit actuator 11, a rotating plate 12 rotatably coupled through the slit actuator 11, a cutting blade part 20 coupled to the rotating plate 12, an adhesive supply part 30 coupled to the cutting blade part 20 for supplying an adhesive, and an adhesive roller part 40 for transferring the adhesive supplied from the adhesive supply part 30 to the side of the germination gap formed on the biodegradable film 1.

[0020] The slit actuator 11 has a cylinder part 11a and a cylinder rod 11b that is retractably coupled to the cylinder part and reciprocally movable on a single axis. That is, according to the operation signal of the control unit, the cylinder rod 11b can change the position of the rotating plate 12 by performing an operation along the outer or inner direction in the cylinder part 11a.

[0021] The rotating plate 12 has a triangular shape that gradually narrows toward the rear from both ends of the plate surface where the cutting blade part 20 and the adhesive roller part 40 are joined, and the upper end of the cylinder rod 11b is rotatably joined to the rear tip end.

[0022] The cutting blade part 20 has a blade support part 21 that is extended and joined to the rotating plate 12 at an upper part on one side, and a cutting blade 22 that is arranged along the vertical direction at the outer end of the blade support part 21.

[0023] The adhesive supply part 30 includes an adhesive supply main body 31 that is fixed along the vertical direction to the blade support part 21, an adhesive supply path 32 that is arranged at the lower part of the adhesive supply main body 31 and functions as a movement path for the adhesive, and a roller ball 33 that is attached to the lower end of the adhesive supply path. The roller ball 33 has a function similar to that of the ball arranged at the tip of a ballpoint pen, and enables the supply of the adhesive in the adhesive supply path 32 to the adhesive roller part 40 through contact with the roller ball 33 when the adhesive roller part 40 rotates. Through this, the adhesive supplied onto the outer peripheral surface of the adhesive roller part 40 is supplied to the side of the germination gap formed on the biodegradable film by the rotation of the adhesive roller part.

[0024] The adhesive roller part 40 includes a roller support part 41 that is extended and joined to the rotating plate 12 at a lower part on one side, and an adhesive roller 42 that is rotatably joined on the roller support part 41 and supplies the adhesive supplied through the roller ball 33 of the adhesive supply part to the side of the germination gap formed on the biodegradable film.

[0025] The seed supply unit 50 includes a seed supply hopper 51, a seed supply hose 52 connected to the lower part of the seed supply hopper 51 for transferring seeds to the side of the germination gap formed on the biodegradable film, a seed supply nozzle 53 coupled to the lower end of the seed supply hose 52, a seed collection hose 54 connected to the upper part of the seed supply hopper 51 for collecting seeds leaked from the germination gap formed on the biodegradable film, and a seed bowl 55 arranged at the lower end of the seed collection hose 54 for temporarily storing seeds detached from the germination gap formed on the biodegradable film.

[0026] When a part of the seeds supplied to the biodegradable film through the seed supply nozzle 53 detaches, timely recovery of the seeds is enabled through a structure that causes them to fall into the seed bowl 55 arranged on the lower side of the seed supply nozzle 53.

[0027] Looking at the overall process of attaching seeds to the biodegradable film to produce the seed film, it is as follows.

[0028] First, simultaneously with the start, the incision and adhesion part 20 that had been lowered downward and to the right rotates through the incision actuator 11 and is positioned vertically. While unwinding the biodegradable film roll wound from the mulching film supply unit 2, a germination gap is created with the cutting blade 22, and an environmentally friendly adhesive is applied between the germination gaps formed by the cutting blade part through the adhesive supply unit 30. At this time, the adhesive is supplied through a roller ball 33 having a tubular structure like a ballpoint pen. The seeds are transferred and supplied with air through the seed supply hose 52 and the seed supply nozzle 53 in order to minimize damage to the seeds.

[0029] Seeds are dropped and adhered to the adhesive application site through the adhesive supply unit 30, and the seeds that have not yet adhered are recovered again by the air inflow method through the seed bowl and the seed collection hose.

[0030] The mulching film laying unit 60 includes a drip hose supply unit 61, an upper alignment roller 63 that advances a primary pre-alignment operation for the drip hose 62 that unfolds from the drip hose supply unit, a fertilizer applicator 80 that supplies a predetermined amount of fertilizer to the drip hose while rotating, a fertilizer supply pipe 67 that houses the drip hose 62 in a state of being continuously provided at the lower end of the fertilizer applicator 80, a plurality of roller members 64, 65 for integrally positioning the seed film on the upper part of the supplied drip hose, and a rotary tiller 70 that enables the scattering of soil so as to easily scoop up the soil of the farmland onto the seed film spread on the farmland.

[0031] The plurality of roller members 64, 65 include a touch roller 64 that guides the first lamination between the drip hose 62 to which fertilization has been performed through the fertilizer supply pipe 67 and the supplied seed film, and a deployment roller 65 that stably spreads the combined body between the laminated seed film and the drip hose on the farmland.

[0032] Looking at the process of laying the biodegradable film with seeds attached on the farmland using a laying machine towed by a tractor (T), it is as follows.

[0033] First, a pre-alignment operation is carried out on the drip hose 62 that unfolds from the drip hose supply unit 61, and a certain amount of fertilizer is transmitted to the drip hose 62 through the fertilizer applicator 80.

[0034] While spreading the seed film on the farmland, the drip hose is buried under the seed film. At this time, the drip hose 62 is positioned below the seed film through the lower touch roller 64 via the upper alignment roller 63.

[0035] In order to be laid in a state where the seed film and the drip hose are integrated, it simultaneously passes through the deployment roller 65. Side dressing of fertilizers is performed under the seed film.

[0036] While spreading the seed film laminated on the drip hose over the farmland, cover it with the soil scooped up from the farmland through a rotary tiller on top of the seed film. At this time, to facilitate scooping up the soil of the farmland, stack a soil scattering plate perpendicular to the rotation direction of the rotary tiller to facilitate the scattering of the soil.

[0037] The seed film production apparatus according to the present invention produces a seed film by supplying, using a seed applicator in a state where damage to seeds is minimized, a mulching film which is a biodegradable film derived from plants supplied with an environmentally friendly adhesive applied through a slit adhesive portion.

[0038] The above description is merely an exemplary explanation of the technical idea of the present invention, and those skilled in the art will be able to make various modifications and variations without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not for limiting the technical idea of the present invention, but for explanation purposes, and the scope of the technical idea of the present invention is not limited by such embodiments. The protection scope of the present invention must be interpreted according to the scope of the claims, and any technical idea within the equivalent scope must be interpreted as being included in the scope of rights of the present invention.
