Description

Technical Field

[0001] The present invention relates to the technical field of irrigation devices, and more specifically, to an agricultural automatic irrigation device. Background Art

[0002] Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation, and micro-irrigation. Traditional surface irrigation includes border irrigation, furrow irrigation, flood irrigation, and wild flooding. However, such irrigation methods often consume a large amount of water and have a low water utilization rate, which is a very unreasonable agricultural irrigation method. In addition, ordinary sprinkler irrigation technology is a relatively common irrigation method in China's agricultural production. However, the water utilization efficiency of ordinary sprinkler irrigation technology is also not high. Modern agricultural micro-irrigation technologies include micro-sprinkler irrigation, drip irrigation, subsurface irrigation, etc. These irrigation technologies generally have good water-saving performance and a higher water utilization rate than traditional irrigation modes. Modern scientific irrigation technology can not only effectively utilize limited water resources, alleviate the severe situation of excessive groundwater extraction and land subsidence, but also, equally importantly, improve the growth conditions of crops, fruit trees, etc. by organically combining with precise fertilization, increase the yield per unit area and the fruit quality, and have good social and economic benefits.

[0003] The existing agricultural automatic irrigation devices have the following defects: 1. There are many types of agricultural irrigation devices. For large areas of farmland that require mechanized sowing and harvesting, in order to facilitate the operation of agricultural machinery, buried irrigation devices are mostly used. The telescopic pipes of such irrigation devices are usually buried 40 cm to 1.5 m underground. However, in arid regions, the ground dries quickly, and it is difficult for the telescopic pipes to drill out from the ground during operation. During irrigation, it is extremely easy to cause damage to the buried irrigation devices, and the installation and maintenance costs are relatively high; 2. Some farmlands use inserted irrigation devices. However, such irrigation devices are not convenient for the operation of agricultural machinery, and the irrigation devices inserted above the ground have low stability during operation, occupy a large area, and during the growth of crops, the height of the nozzles needs to be adjusted, and the workload of height adjustment operation is relatively large; 3. In order to perform large-scale irrigation operations on farmland, some farmlands choose rocker atomizing spray guns for irrigation operations. Its internal structure is complex, the installation cost is relatively high, and at the same time, the maintenance and replacement costs are relatively high when the irrigation device is damaged, and the irrigation uniformity is relatively low; 4. During irrigation, a large amount of water will directly penetrate deep into the ground, causing waste of water resources. At the same time, a large amount of water will accumulate at the root parts of crops, resulting in the roots of crops being soaked in water for a long time, and the phenomenon of root rot occurs, thus affecting the growth of crops.

[0004] Therefore, an agricultural automatic irrigation device is proposed to solve the above problems by an irrigation device buried on the ground surface and a recovery hopper for recovering the surplus water. Summary of the Invention

[0029] Optionally, the residual liquid recovery mechanism 12 further includes a filter plate 1202 fixedly connected to the top end of the recovery hopper 1201. There are three groups of filter plates 1202 and they are communicated with the inner cavity of the recovery hopper 1201. A grid plate 1203 is fixedly connected inside the filter plate 1202. A clamping frame 1204 is provided at the top end of the grid plate 1203. The clamping frame 1204 is clamped with the filter plate 1202. A permeable membrane 1205 is fixedly connected inside the clamping frame 1204.

[0030] Optionally, the residual liquid recovery mechanism 12 further includes a hose 1206 fixedly connected to the inner wall of the recovery hopper 1201. The hose 1206 is communicated with the guiding connection pipe 11. One end of the hose 1206 is fixedly connected with a drainage column 1207, and a concave hole is formed in the outer end of the drainage column 1207. The purpose of this setting is that during the operation of the pumping pump 10, the drainage column 1207 drains water into the interior of the hose 1206.

[0031] In this embodiment, when installing the irrigation device, first dig an embedded groove at the surface position of the farmland, install multiple groups of connecting pipes 1 according to the irrigation requirements, and use conduits to connect the multiple groups of connecting pipes 1. After burying the connecting pipes 1, perform the filling operation and make the top end of the sleeve 2 flush with the bottom surface. During the irrigation of crops, as water flows inside the connecting pipe 1, the water enters the telescopic pipe 3 inside the sleeve 2. The water pressure drives the telescopic pipe 3 to slide inside the sleeve 2 and makes the telescopic pipe 3 extend out of the sleeve 2. At the same time, water sprays out from the nozzle 5 to irrigate the surrounding crops. The spray holes at the outer end of the nozzle 5 are flat, so that the water flow sprayed by the nozzle 5 is dispersed, improving the uniformity of crop irrigation. Since the heights of crops are different in different growth cycles, the nozzles 5 with lower heights directly spray on the stalks of plants. The relatively large water pressure easily causes the crops to tilt, and at the same time, it also affects the irrigation range. At this time, according to the height of the crops, rotate the screw 604 at the top of the mounting plate 601. The rotating screw 604 drives the positioning block 603 to move inside the side plate 602. During irrigation, the sliding plate 4 at the bottom of the telescopic pipe 3 abuts against the bottom of the positioning block 603, so as to fix the elongation amount of the telescopic pipe 3 inside the sleeve 2. The adjustment method is simple, the structure is simple, and the installation cost of the irrigation device is relatively low. During irrigation, water enters the spiral conduit 703 inside the rotating sleeve 702. The impact force generated by the water flow makes the rotating sleeve 702 rotate inside the clamping sleeve 701, so that the nozzle 5 rotates 360 degrees at the top of the telescopic pipe 3. The rotating nozzle 5 increases the irrigation range. The water absorption capacity of the soil is limited. When more water is poured, some water is difficult to completely penetrate into the ground. The excessive water makes the roots of the crops soak in the water for a long time, which is extremely likely to cause the crops to rot and even develop diseases, affecting the growth of the crops. When the water seeps into the ground, the excess water penetrates from the top of the filter plate 1202 into the inside of the recovery hopper 1201 for collection. During the process of recovering the excess water, the permeable membrane 1205 separates the soil and water, so that the clean water is recovered into the inside of the recovery hopper 1201. The provided grid plate 1203 supports the permeable membrane 1205 to prevent the permeable membrane 1205 from collapsing and being damaged. In some areas, it is relatively dry and there is less rain. The recovered water can be reused, achieving the purpose of saving water resources. When reusing the recovered water, the water flow inside the connecting pipe 1 can be reduced, and the water pump 10 is controlled to discharge the water in the recovery hopper 1201 into the connecting pipe 1 through the diversion pipe 9, so as to achieve the effect of water conservation.

[0032] Embodiment 2 Referring to Figures 1 to 7 , this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: Compared with Embodiment 1, further, a mounting base 13 is fixedly connected to the bottom end of the connecting pipe 1. A positioning pin 14 is slidably connected inside the mounting base 13, and a fixing pin 15 is slidably connected to the top end of the mounting plate 601. The purpose of this setting is that the provided mounting base 13 has an anti-settlement effect to prevent the connecting pipe 1 from sinking due to wet soil. The provided positioning pin 14 facilitates fixing the mounting base 13 connected to the connecting pipe 1 in the embedded groove. The provided fixing pin 15 has three groups and is arranged in a triangle to increase the gripping strength of the mounting plate 601.

[0033] Optionally, filter pipes 16 are threadedly connected to both ends of the connecting pipe 1. The filter pipes 16 are communicated with the connecting pipe 1. A funnel 17 is snap-connected inside the filter pipe 16. The cross-section of the funnel 17 is in a W shape. An assembly pipe 18 is threadedly connected to the outer end of the filter pipe 16, and a fixing nut 19 is threadedly connected to the outer end of the assembly pipe 18. The purpose of this setting is that the water for crop irrigation is mostly introduced from ponds and pools. However, there is a lot of sediment in ponds and pools, and the sediment is extremely likely to block the connecting pipe 1, resulting in a decrease in the water pressure inside the nozzle 5 and a reduction in the irrigation range of the nozzle 5. After the water enters the filter pipe 16, the internal funnel 17 filters the sediment. The funnel 17 arranged in a W shape prevents the sediment from adhering to the bottom end and the side wall of the funnel 17, thereby reducing the water flux inside the connecting pipe 1.

[0034] In this embodiment, when installing the connecting pipe 1, the mounting base 13 at the bottom of the connecting pipe 1 is fixed inside the embedded groove using the positioning pin 14. After landfill, the mounting plate 601 at the top end of the sleeve 2 is fixed using the fixing pin 15. When assembling multiple groups of connecting pipes 1, one end of the external pipeline is inserted into the assembly pipe 18 and fixed using the fixing nut 19. The installation method is simple. During the flow of water, the internal funnel 17 of the filter pipe 16 filters the sediment to prevent the inner side of the connecting pipe 1 from being blocked by sediment.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
