Description

Technical Field

[0001] This utility model relates to the field of soilless cultivation equipment technology, specifically to an automatic irrigation device for substrate trough cultivation. Background Technology

[0002] Substrate cultivation is a soilless cultivation technique that uses solid substrates (such as vermiculite, perlite, peat, and coconut coir) to immobilize plant roots and combines this with a drip irrigation system to supply nutrient solution and oxygen, providing the plants with the nutrients and environment necessary for growth. Its core advantages lie in its simple equipment, low cost, and ability to effectively reduce soil-related diseases, conserve water and fertilizer resources, and simultaneously improve crop yield and quality. A variety of substrates are available, and they can be mixed and formulated according to crop needs, ensuring both aeration and water retention while buffering nutrient supply.

[0003] However, most of the drip irrigation capillaries in drip irrigation devices currently used in substrate cultivation are in direct contact with the substrate, which can easily cause substrate particles to seep into the dripper channel, leading to dripper blockage. This can result in localized reductions in irrigation volume and uneven water output. Furthermore, the substrate remains moist for extended periods during drip irrigation, and the outer wall of the capillaries is in continuous contact with a high-humidity environment, which accelerates the aging of the plastic material and reduces the lifespan of the capillaries. Utility Model Content

[0004] The purpose of this invention is to provide an automatic irrigation device for substrate trough cultivation to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic irrigation device for substrate trough cultivation includes a water and fertilizer integrated machine, planting troughs, a film, a substrate, and drip irrigation capillary tubes. The film is laid inside the planting trough, and the substrate fills the inside of the planting trough and contacts the inner wall of the film. There are three planting troughs. The rear side of the water and fertilizer integrated machine is connected to a main water pipe via a solenoid valve. The rear side of the main water pipe is connected to three connecting pipes. There are three drip irrigation capillary tubes, which are distributed above the three planting troughs. Positioning components are fixedly installed on the rear side of each of the three planting troughs. The front and rear sides of each of the three drip irrigation capillary tubes are respectively engaged with the corresponding connecting pipes and positioning components. Two limiting components are provided on the top of each of the three planting troughs, which are symmetrically distributed front and back. Support components are provided on the top of each of the three planting troughs. The front and rear sides of each of the three drip irrigation capillary tubes are respectively connected to the two limiting components on the corresponding sides.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, all of the positioning components include an L-shaped support plate, a positioning rod is fixed to the front side of the vertical section of the L-shaped support plate, the rear side of the drip irrigation capillary tube is sleeved on the outside of the positioning rod and fixed by a snap ring, and the front side of the drip irrigation capillary tube is sleeved on the outside of the connecting pipe and fixed by a snap ring.

[0009] Furthermore, all of the aforementioned limiting components include a placement seat, a first fixing ring, and a second fixing ring. The placement seat is fixed to the top of the planting trough by fasteners. An installation groove is provided inside the placement seat. The first fixing ring is located on the top of the placement seat and is partially located inside the installation groove. The second fixing ring is located above the first fixing ring. The top of the second fixing ring is fixed to the placement seat by fasteners passing through the first fixing ring. The front and rear sides of the drip irrigation capillary tube extend into the space formed by the front and rear first fixing rings and the second fixing rings.

[0010] Furthermore, the connecting pipe extends into the space formed by the first and second fixing rings on the front side, and the positioning rod extends into the space formed by the first and second fixing rings on the rear side.

[0011] Furthermore, all of the support components include two sliding blocks and a support plate. The two sliding blocks are symmetrically distributed from left to right and are slidably connected to the top of the planting trough. Each of the two sliding blocks has a placement groove on its top. The support plate is placed between the two sliding blocks through the placement groove, and its top is in contact with the bottom of the drip irrigation capillary tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Within the space formed by the first and second fixing rings, the drip irrigation capillary tube is fixed by the connecting pipe and positioning rod under the action of the snap ring, thus ensuring that the drip irrigation capillary tube does not come into contact with the substrate during use. Furthermore, the drip irrigation capillary tube is stably supported by the support plate, thereby ensuring that the drip irrigation capillary tube is located above the substrate, maintaining a certain height from the substrate, preventing substrate impurities from seeping in during planting, reducing contact with high humidity environments, and extending the service life of the capillary tube.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] Example 1, such as Figures 1 to 7 As shown, an automatic irrigation device for substrate trough cultivation includes a water and fertilizer integrated machine 1, planting troughs 2, a film 3, a substrate 4, and drip irrigation capillary tubes 7. The film 3 is laid inside the planting trough 2, and the substrate 4 is filled inside the planting trough 2 and in contact with the inner wall of the film 3. There are three planting troughs 2. The rear side of the water and fertilizer integrated machine 1 is connected to a main water pipe 5 through a solenoid valve. The rear side of the main water pipe 5 is connected to three connecting pipes 6. There are three drip irrigation capillary tubes 7, which are distributed above the three planting troughs 2 respectively. Positioning components 8 are fixedly installed on the rear side of each of the three planting troughs 2. The front and rear sides of the three drip irrigation capillary tubes 7 are respectively engaged with the corresponding connecting pipes 6 and positioning components 8. Two limiting components 9 are provided on the top of each of the three planting troughs 2, and they are symmetrically distributed front and back. Support components 10 are provided on the top of each of the three planting troughs 2. The front and rear sides of the three drip irrigation capillary tubes 7 are respectively connected to the two limiting components 9 on the corresponding sides.

[0025] The planting trough 2, the film 3, and the substrate 4 form a growing environment for substrate-grown crops. Under the action of the integrated water and fertilizer machine 1, water and fertilizer can be delivered in a timely and quantitative manner. The integrated water and fertilizer machine 1 can also be connected to multiple main water pipes 5, which facilitates irrigation of large-area substrate-grown crops (this is a technical means well known to those skilled in the art, so it will not be described in detail). The front and rear sides of the drip irrigation capillary tube 7 are restricted by the connecting pipe 6 and the positioning component 8, so that under the action of the support component 10, the drip irrigation capillary tube 7 is positioned above the substrate 4 during use and does not come into contact with the substrate 4. The crops are also planted by being interspersed on the left and right sides of the drip irrigation capillary tube 7.

[0026] Example 2 is a further improvement based on Example 1, and is as follows: all positioning components 8 include an L-shaped support plate 801. A positioning rod 802 is fixed to the front side of the vertical section of the L-shaped support plate 801. The rear side of the drip irrigation capillary tube 7 is sleeved on the outside of the positioning rod 802 and fixed by a snap ring. The front side of the drip irrigation capillary tube 7 is sleeved on the outside of the connecting pipe 6 and fixed by a snap ring.

[0027] With this configuration, when installing the drip irrigation capillary tube 7, the front side of the drip irrigation capillary tube 7 can be provided with the necessary support through the connecting pipe 6, and the rear end of the drip irrigation capillary tube 7 can be provided with the necessary support through the positioning rod 802. The snap ring is a commonly used means of fixing the drip irrigation capillary tube 7, so it will not be described in detail.

[0028] Example 3 is a further improvement on Example 2, and is as follows: All limiting components 9 include a placement seat 901, a first fixing ring 902, and a second fixing ring 903. The placement seat 901 is fixed to the top of the planting trough 2 by fasteners. The placement seat 901 has an installation groove 904 inside. The first fixing ring 902 is located on the top of the placement seat 901 and is partially located inside the installation groove 904. The second fixing ring 903 is located above the first fixing ring 902. The top of the second fixing ring 903 is fixed to the placement seat 901 by fasteners passing through the first fixing ring 902. The front and rear sides of the drip irrigation capillary tube 7 extend into the space formed by the first fixing ring 902 and the second fixing ring 903 on the front and rear sides.

[0029] With this configuration, the first fixing ring 902 is placed on top of the placement base 901, and then the second fixing ring 903 is connected to the first fixing ring 902. The installation of the first fixing ring 902 and the second fixing ring 903 is completed under the action of the fasteners. Since the drip irrigation capillary tube 7 needs to be installed on both the front and rear sides, the space formed by the first fixing ring 902 and the second fixing ring 903 on the front and rear sides allows the front and rear sides of the drip irrigation capillary tube 7 to extend into its interior, which facilitates the support and stability after subsequent installation. In addition, a rubber pad can be placed inside the installation groove 904 to provide certain support for the first fixing ring 902, thereby enhancing the stability of the drip irrigation capillary tube 7 during subsequent use.

[0030] Example 4 is a further improvement on Example 3, and it is as follows: the connecting pipe 6 extends into the space formed by the first fixing ring 902 and the second fixing ring 903 on the front side, and the positioning rod 802 extends into the space formed by the first fixing ring 902 and the second fixing ring 903 on the rear side.

[0031] With this configuration, after the connecting pipe 6 is fitted onto the front side of the drip irrigation capillary tube 7, its position is restricted by the action of the first fixing ring 902 and the second fixing ring 903 on the front side, and the fixing effect of the buckle ring is strengthened. After the positioning rod 802 is fitted onto the rear side of the drip irrigation capillary tube 7, its position is restricted by the action of the first fixing ring 902 and the second fixing ring 903 on the rear side, and the fixing effect of the buckle ring is strengthened. With the synergistic action of the front and rear, the position of the drip irrigation capillary tube 7 on both the front and rear sides is ensured.

[0032] Example 5 is a further improvement based on Example 1, and is as follows: All support components 10 include two sliding blocks 1001 and a support plate 1002. The two sliding blocks 1001 are symmetrically distributed from left to right and are slidably connected to the top of the planting trough 2. The top of each of the two sliding blocks 1001 is provided with a placement groove 1003. The support plate 1002 is placed between the two sliding blocks 1001 through the placement groove 1003, and its top is in contact with the bottom of the drip irrigation capillary tube 7.

[0033] This design prevents the middle of the drip irrigation capillary tube 7 from bending under the weight of water. The support plate 1002 supports the middle of the drip irrigation capillary tube 7, ensuring the height of the drip irrigation capillary tube 7 during use. Furthermore, the position of the support plate 1002 can be adjusted by the two sliding blocks 1001, which is very convenient. In cultivation processes with longer lengths, the support components 10 can be added as needed to support the drip irrigation capillary tube 7, reducing the occurrence of bending.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
