Description

Technical Field

[0001] The invention relates to a drip irrigation trough in the field of irrigation technology, in particular to a drip irrigation trough manufactured by plastic lamination and a use method thereof. Background Art

[0002] In desert areas, water evaporation is a serious problem for irrigation agriculture. In irrigation areas far away from the water source, the amount of water evaporated is often far less than what the plants need.

[0003] In the prior art, metal or plastic cloth is often used as a carrier of water and soil. When metal is used, the water evaporates more quickly, but when plastic cloth is used, it is not possible to shape the plants because the plastic cloth is a soft material, which is not beautiful.

[0004] Therefore, in order to solve the above-mentioned existing technical problems, it is urgent to propose a drip irrigation trough and a use method thereof. Summary of the invention

[0005] In order to solve the problems of the prior art mentioned above, a main purpose of the present invention is to relate to a drip irrigation trough body, which includes a bottom plate, two side plates and at least one water supply trough. The two side plates are respectively connected to the two sides of the bottom plate, and together with the bottom plate, form a receiving space for carrying at least one medium. The at least one water supply trough is arranged on the other side of the side plate relative to the receiving space in the horizontal direction, and the at least one water supply trough is used to carry at least one liquid. Each of the at least one water supply troughs includes a plurality of sub-drip areas arranged from bottom to top in the vertical direction, and the lowest sub-drip area of ​​the plurality of sub-drip areas is communicated with the receiving space.

[0006] In a preferred embodiment, the plurality of sub-drip areas further include a plurality of drip layers, which are individually arranged between every two adjacent plurality of sub-drip areas, and each of the plurality of drip layers includes a plurality of holes for passing the at least one liquid.

[0007] In a preferred embodiment, the plurality of sub-drip areas have different heights in the vertical direction.

[0008] In a preferred embodiment, the holes of the plurality of sub-drip areas have different sizes.

[0009] In a preferred embodiment, the density of the at least one hole in different areas of each of the sub-drip areas is different.

[0010] In a preferred embodiment, the density of the at least one hole in the plurality of sub-drip areas increases from small to large from top to bottom in the vertical direction.

[0011] In a preferred embodiment, in the vertical direction, adjacent holes of one of the drip layers between the lowermost sub-drip area and the upper sub-drip area are closed, so that the at least one liquid can only pass through half of the holes to reach the lowermost sub-drip area.

[0012] In a preferred embodiment, the bottom plate, the side plate and the at least one water supply trough are made of paper products through lamination.

[0013] In a preferred embodiment, a paperboard is formed into the bottom plate, the side plate and the at least one water supply trough through a concave folding process and a hot-melt process.

[0014] In order to solve the problems of the above-mentioned prior art, a main purpose of the present invention is to relate to a method for using a drip irrigation trough as mentioned above, which comprises: first, forming a groove corresponding to the shape of the drip irrigation trough in soil; then, placing the drip irrigation trough into the groove; then, placing the at least one medium into the receiving space; then, the topmost sub-drip area of ​​the plurality of sub-drip areas is connected to the at least one liquid; finally, the at least one liquid is transported to the receiving space to contact the at least one medium after it sequentially descends from the topmost sub-drip area to the bottommost sub-drip area through the topmost sub-drip area.

[0015] The present invention brings the following technical benefits: Compared with the prior art, the trough body of the present invention is made of paper coating. Since paper has certain toughness, strength, flatness, water absorption and decomposability, it can be used to shape the plants in the pipeline to make the overall appearance beautiful, and can also help retain water on the soil surface. In addition, the use of a material that is easier to decompose and waterproof than plastic as a coating material also utilizes the characteristics of recycled paper that can be moderately decomposed in the natural environment to reduce the residual harmful substances in the planting process, such as: plastics, heavy metals and other substances. Furthermore, this case can also cooperate with the city government to solve the local waste paper problem. In addition to reducing the waste gas and pollution in the papermaking process, the effective recycling of waste paper can save the waste of raw materials. The most important thing is that the drip irrigation trough body can be made through the integrally formed cardboard through the concave folding and heat fusion process, and then the multiple sub-drip areas of the trough body arranged from top to bottom are used to reduce the evaporation of water, so that the water can be transported to a distant place in the pipeline even in desert areas.

[0034] The following descriptions of the embodiments are used in conjunction with the accompanying drawings to illustrate specific embodiments of the present invention that can be implemented. Directional terms mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inner", "outer", "side", etc., are only used to illustrate the directions of the drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0035] refer to Figures 1 to 4 . Figure 1 A schematic diagram of a paperboard 10 according to the present invention is shown; Figure 2 A schematic diagram of a drip irrigation trough 20 according to the present invention is shown; Figure 3 Draw a basis Figure 2 A magnified schematic diagram of the circled area; Figure 4 Draw a basis Figure 2 A schematic cross-sectional view of a water supply tank 23 in the direction of arrow A.

[0036] See also Figure 1As shown, the paperboard 10 is made of a paper product by laminating. Preferably, the paper product can be recycled paper. The laminating material can be selected from PLA, lignin-like materials that are easy to decompose, but not limited to this. It can be noted that there are two solid lines and two dotted lines in the paperboard 10, which are only used for illustration. Taking the left side as an example, the paperboard 10 is first folded 180 degrees to the right along the dotted line (the first fold), at which time the left first area (the left side of the left dotted line) and the left second area (the right side of the left dotted line and the left side of the left solid line) of the paperboard 10 overlap to form a water supply trough 23; then, it is folded 90 degrees to the right along the left solid line (the second fold), that is, the left first area is equivalent to the side plate 22 and the central area (the right side of the left black line and the left side of the right black line) is a bottom plate 21; similarly, the same operation is performed on the right side of the paperboard 10 to obtain a drip irrigation trough 20. The angles of the first fold and the second fold are not limited to this and can be changed according to needs. Among them, a hot melt process is also used to form the various components described later (to be discussed later).

[0037] See also Figure 2 As shown, after the above molding, the drip irrigation trough 20 includes a bottom plate 21, two side plates 22 and two water supply grooves 23. In this preferred embodiment, the second concave angle is 90 degrees to form a U-shaped groove of the drip irrigation trough 20 and both sides of the side plates 22 are provided with water supply grooves 23, but the concave angle and the number of water supply grooves 23 are not limited thereto. For example, the water supply groove 23 can be provided only on one side.

[0038] Please also refer to Figure 2 and Figure 3 As shown, the two side plates 22 are respectively connected to the two sides of the bottom plate 21, and together with the bottom plate 21, form a receiving space 24 for carrying at least one medium. The at least one medium is usually a mixture of soil and seeds in the present invention (not shown). Furthermore, the two water supply troughs 23 are horizontally arranged on the other side of the side plate 22 relative to the receiving space 24, and the two water supply troughs 23 are used to carry at least one liquid. Preferably, the at least one liquid is usually water or water containing nutrients, such as fertilizer. Each of the two water supply troughs 23 includes five sub-drip areas 26 arranged from bottom to top in the vertical direction (the preferred embodiment uses five sub-drip areas 26 as an illustration), and the lowest sub-drip area 26 is connected to the receiving space 24. Figure 3 In the figure, the direction of arrow B is the moving direction of the at least one liquid in the vertical direction under the force of gravity.

[0039] Preferably, the five sub-drip areas 26 further include four drip layers 27, which are respectively disposed between every two adjacent sub-drip areas 26, and each of the drip layers 27 includes a plurality of holes 28 for passing the at least one liquid. Figure 3 In the embodiment, the plurality of holes 28 are the blank areas of the dotted lines of the drip layer 27, that is, the plurality of holes 28 may be of the same size or of different sizes; for example, Figure 4 In the embodiment, the plurality of holes 28 are solid lines between the drip layers 27, and the plurality of holes 28 are arranged from top to bottom, and the spacing between the holes 28 is gradually reduced. However, according to actual use requirements, the height of the sub-drip area 26 can be gradually increased from bottom to top as in the preferred embodiment, or at least one hole 28 with different densities or sizes can be arranged in different areas of the drip layer 27.

[0040] Preferably, the hot melt process can be adjusted so that the adjacent holes 28 of a drip layer 27 between the bottom sub-drip area 26 and the upper sub-drip area 26 are closed, so that at least one liquid can only pass through half of the holes 28 to reach the bottom sub-drip area 26.

[0041] The water supply trough 23 is formed after the paperboard 10 is folded 180 degrees. Figure 2 As in the macroscopic perspective, Figure 3 From a microscopic perspective, the paperboard 10 has a certain thickness and deformability, so before the at least one liquid is injected, the water supply tank 23 will be like Figure 3 and Figure 4 The water supply tank is a rectangular parallelepiped; after the at least one liquid is injected, the water supply tank may be squeezed by the liquid and the carrier medium to form a plurality of connected irregular shapes.

[0042] The manufacturing process of the drip irrigation trough 20 is as follows: the first stage, the sub-drip area 26. Strictly speaking, after the first concave folding, only the periphery of the water supply trough 23 is formed, and the sub-drip area 26 has not yet been formed; the paperboard 10 that has passed the first concave folding is subjected to four hot-melt processes to form the following Figure 4 The four drip layers 27 are formed. The second stage is to accommodate the space 24. After the sub-drip area 26 is completed, the second concave fold is performed, and then the left area of ​​the paperboard 10 and the central area of ​​the paperboard 10 are hot-fused to achieve fixation and make the paperboard 10 Figure 3 The sub-drip area 26 at the bottom forms a water-permeable area in dashed lines.

[0043] Preferably, the hot melting process may be high frequency or other technical means with the same effect, but is not limited thereto.

[0044] In this preferred embodiment, Figure 4 For example, the drip irrigation tank 20 is 1,000 meters long, and the cross section is a U-shaped bottom plate 21 of 40 cm and the height of the two side plates 22 of 15 cm. The cross section of the water supply tank 23 is a rectangle with a length of 15 cm on both sides (i.e. the height of the side plates 22) and a width of 1 cm (adjustable as needed). There are 9 holes 28 (one per 100 meters) between the first and second layers, and the height of the first layer is 5 cm, one hole 28 is set every 10 meters between the second and third layers, and the height of the second layer is 4 cm, one hole 28 is set every 1 meter between the third and fourth layers, and the height of the third layer is 3 cm, one hole 28 is set every 0.1 meters between the fourth and fifth layers, and the height of the fourth layer is 2 cm, and the height of the fifth layer is 1 cm. This arrangement allows water to quickly flow from one end (the water inlet side) of the 1,000-meter-long tube to the other end; the water can then enter the next layer through the nine holes 28 between the first and second layers, reducing the evaporation rate; as the water enters the lower layers, the slower the evaporation rate, and because there are more and more holes 28, the purpose of slow water supply can be achieved.

[0045] Therefore, compared with the irrigation water delivery method of the prior art, the multi-layer sub-drip area 26 of the present invention allows water to first pass through a plurality of holes 28 in the first layer, such as the first layer first flowing down to the second, third, etc. layers, to avoid water staying in the first layer for a long time and being wasted due to evaporation. However, it should be noted that the present invention can arrange the plurality of holes 28 on the two side plates 22 relatively according to actual use requirements, or can be staggered, that is, the two side plates 22 can be designed to have the same number of sub-drip areas 26, the same number of holes 28, the same height of the sub-drip areas 26, and the same density of holes 28; they can also be staggered so that the soil covered by the entire drip irrigation trough 20 can be kept moist.

[0046] Compared with the prior art, the trough body of the present invention is made of paper coating. Since paper has certain toughness, strength, flatness, water absorption and decomposability, it can be used to shape the plants in the pipeline to make the overall appearance beautiful, and can also help retain water on the soil surface. In addition, the use of a material that is easier to decompose and waterproof than plastic as a coating material also utilizes the characteristics of recycled paper that can be moderately decomposed in the natural environment to reduce the residual harmful substances in the planting process, such as plastics, heavy metals and other substances. Furthermore, this case can also cooperate with the city government to solve the local waste paper problem. In addition to reducing the waste gas and pollution in the papermaking process, the effective recycling of waste paper can save the waste of raw materials. The most important thing is that the drip irrigation trough body 20 can be made through the integrally formed cardboard 10 through the concave folding and heat fusion process, and then the multiple sub-drip areas 26 of the trough body arranged from top to bottom are used to reduce the evaporation of water, so that the water can be transported to a distant place in the pipeline even in desert areas.

[0047] Figure 5 A flowchart of the method of using the drip irrigation tank 20 according to the present invention is shown. Figures 1 to 4 The method for using the drip irrigation trough 20 of the present invention is as follows: first, perform step S01 to form a groove corresponding to the shape of the drip irrigation trough 20 in a soil; perform step S02 to place the drip irrigation trough 20 in the groove; perform step S03 to place the at least one medium in the receiving space 24; perform step S04 to connect the at least one liquid to the topmost sub-drip area 26 of the plurality of sub-drip areas 26; perform step S05 to sequentially descend from the topmost sub-drip area 26 to the bottommost sub-drip area 26 before being transported to the receiving space 24 to contact the at least one medium.

[0048] In addition, the drip irrigation trough 210 can preferably be used in deserts and farmland, and there is no limitation here. Before the drip irrigation trough 20 is placed on the soil, the staff will first observe and confirm the site to construct an environment for placing the drip irrigation trough 20, for example: whether the road to the site is unobstructed, whether the site is flat, and whether the site can be powered on. The method of constructing the environment for placing the drip irrigation trough 20 of the present invention is as follows: first, a soil leveling step is performed. During the construction process, appropriate corrections can be made in combination with the actual situation on site, and the soil is leveled to level the ground; a positioning step is performed: positioning is performed in the planned site, the prepared rope is tightened according to the planned orientation, and the length of the bottom plate 21 is drawn along the rope direction with lime, and then the width of the bottom plate 21 is determined. Note that when drawing the line, the long side and the wide side of the bottom plate 21 should be at a 90-degree angle, and the line is drawn; a placement step is performed: a groove corresponding to the shape of the drip irrigation trough 20 is formed in a preset planning area, and the bottom plate 21, the side plate 22 and the at least one water supply trough 23 in the drip irrigation trough 20 are formed by a paperboard 10 through a concave folding process and a hot melt process.

[0049] The above are only preferred embodiments of the present invention. It should be pointed out that a person having ordinary knowledge in the technical field to which the present invention belongs can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the appended claims.
