Description
Technical Field
[0001] The utility model relates to a ditchless rice-snail integrated planting and breeding circulating flowing water cultivation device, which can be applicable to flat fields and mountain terraced fields with scattered heights. Background Art
[0002] "Rice-snail" integrated planting and breeding is one of the seven typical technical models such as rice-fish integrated planting and breeding in China. The main breeding varieties are Chinese field snails, ringed snails, etc. For ditchless "rice-snail" integrated planting and breeding, the field snails are cold-resistant but heat-sensitive, and the water body in paddy fields for breeding is small and the water layer is shallow. In the traditional "static water" rice-snail planting and breeding mode, it is necessary to dig activity spaces such as snail ditches and snail pits for the snails to avoid heat and cold and increase the effective breeding water body, resulting in low breeding yield. By using the natural terrain difference and adopting the micro-flowing water rice-snail planting and breeding mode, due to the inability to recycle the water body in paddy fields, it often leads to the loss of fertilizer in paddy fields and increases agricultural non-point source pollution. All existing paddy field circulating flowing water cultivation technologies involve digging circulating water channels and fish ditches or setting up separate breeding areas, with relatively large investment in field engineering costs, and occupying some paddy field planting areas. Although the proportion of ditches and pits is limited, it also increases the difficulty of stabilizing rice yield and harvesting. To solve the drawbacks of the existing rice-snail integrated planting and breeding mode and the deficiencies of the existing circulating flowing water cultivation technology, we thus propose a ditchless rice-snail integrated planting and breeding circulating flowing water cultivation device. Content of the Utility Model
[0003] Aiming at the deficiencies of the existing technologies, the purpose of the utility model is to provide a ditchless rice-snail integrated planting and breeding circulating flowing water cultivation device. Through the matching of circulating flowing water and oxygenation, small contiguous paddy fields are connected in series to form a large area, forming a new ditchless paddy field circulating flowing water integrated planting and breeding mode, which not only improves the breeding yield and income of paddy fields, but also protects the ecological environment.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] The ditchless rice-snail integrated planting and breeding circulating flowing water cultivation device of the utility model is characterized in that it includes at least two rows of multiple paddy fields arranged in a matrix. In each paddy field, there are a water lifting pit, a water lifting pump, a three-way shunt valve, an upper water inlet pipe, a lower water inlet pipe and a Venturi injector; the water lifting pump is fixedly installed in the water lifting pit of the paddy field, the upper water inlet pipe and the lower water inlet pipe are connected to the water outlet of the water lifting pump through the three-way shunt valve, the upper water inlet pipe and the lower water inlet pipe are respectively arranged in adjacent different paddy fields, and a number of Venturi injectors are arranged at intervals on the upper water inlet pipe and the lower water inlet pipe. After the water lifting pump pumps water from the water lifting pit, it sprays into the paddy field through the Venturi injector to push the breeding water body in the paddy field to form a circular water flow.
[0006] Preferably, the above-mentioned water lifting pits are all arranged at the diagonal corners of adjacent two rice fields, and wire mesh fences are arranged on the water lifting pits to prevent foreign objects from entering the water lifting pits along with the water flow and blocking the water lifting pumps.
[0007] Preferably, the mesh number of the above-mentioned wire mesh fence is 20 meshes.
[0008] Preferably, the above-mentioned upper water inlet pipe and lower water inlet pipe are both installed below the rice field water surface on the side of the rice field ridge; the upper water inlet pipe and the water lifting pump are installed in the same rice field, and the lower water inlet pipe is installed in the next rice field; the upper water inlet pipe and the lower water inlet pipe installed on the same water lifting pump form a right angle, and the upper water inlet pipe and the lower water inlet pipe in the same rice field are parallel and opposite to each other.
[0009] Preferably, a Venturi injector is installed every 1 meter on the above-mentioned upper water inlet pipe and lower water inlet pipe; the air inlet of the air guide pipe of the Venturi injector is arranged above the rice field water surface so as to be able to suck air to oxygenate the water body when the Venturi injector works.
[0010] Preferably, the installation directions of the above-mentioned Venturi injectors are all at a horizontal 45° angle along the water flow direction of the water inlet pipe to achieve inclined jet flow.
[0011] Preferably, the number of rice fields in each row is an even number.
[0012] Preferably, the above-mentioned rice fields are rectangular in shape, and they are flat fields or mountain terraced fields with high and low levels.
[0013] When the ditchless integrated rice and snail polyculture circulating flowing water aquaculture device of the present utility model works, the water body flows into adjacent two rice fields through the water lifting pump, the three-way flow valve and the water inlet pipe, forming circulating flowing water between the rice fields; the water flow reaches the purpose of oxygenation through the Venturi injector, and the ejected water flow promotes the formation of a circulating flow of the aquaculture water body in the rice field, realizing the circulating flow and exchange of the integrated rice and snail polyculture water body.
[0014] Compared with the prior art, the present utility model has the following beneficial effects:
[0015] The ditchless integrated rice and snail polyculture circulating flowing water aquaculture device has a simple structure, is easy to operate, has a low cost, is economical and practical, and is applicable not only to flat fields but also to mountain terraced fields with high and low levels; the integrated rice and snail polyculture water body forms circulating flowing water between the rice fields and circular water flow in the rice fields through the water lifting pump, the three-way flow valve, the water inlet pipe and the Venturi injector, further promoting the exchange and diffusion of the integrated rice and snail polyculture water body while oxygenating, greatly improving the environmental conditions of the integrated rice and snail polyculture water body, avoiding the integrated rice and snail polyculture water body from becoming "stagnant water", effectively improving the survival rate, aquaculture yield and income of snail aquaculture, and also protecting the ecological environment and reducing agricultural non-point source pollution; the water flow formed in the rice field can also make the fed snail feed evenly distributed in the field to form a feeding ground, reducing the waste of feed;

Detailed Embodiment
[0021] To make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are given below in conjunction with the accompanying drawings and described in detail as follows, but the present utility model is not limited thereto.
[0022] Refer to Figure 1 、 Figure 2 and Figure 3 for the embodiments of:
[0023] The ditchless integrated rice and snail polyculture circulating flow aquaculture device of the present utility model is formed by arranging two rows of paddy fields 1 in a matrix. Of course, it can also be three rows, four rows, or multiple rows of paddy fields arranged flush to form a matrix. In this embodiment, the number of single-row paddy fields is an even number (it can also be an odd number).
[0024] A water-lifting pit 2, a water-lifting pump 3, a three-way shunt valve 4, an upper inlet pipe 5, a lower inlet pipe 6 and a venturi injector 7 are provided in the paddy field; the upper inlet pipe 5 and the lower inlet pipe 6 are connected to the water outlet of the water-lifting pump 3 through the three-way shunt valve 4. The upper inlet pipe 5 and the lower inlet pipe 6 are respectively arranged in adjacent different paddy fields 1. Multiple venturi injectors 7 are arranged at intervals on the upper inlet pipe 5 and the lower inlet pipe 6 (the venturi injector 7 is a pipe with a trumpet shape at both ends, one end is connected to the inlet pipe, and the other end is used as the water outlet). After the water-lifting pump 3 pumps water from the water-lifting pit 2, it sprays into the paddy field 1 through the venturi injector 7 to drive the aquaculture water body in the paddy field 1 to form a circular water flow.
[0025] Specifically, the water lifting pits 2 are all arranged at the diagonal corners of two adjacent rice fields 1. A wire mesh fence 8 with a mesh size of 20 meshes is provided on the water lifting pit 2 to prevent sundries such as snails and weeds from entering the water lifting pit 2 with the water flow and blocking the water lifting pump 3.
[0026] In this embodiment, the water lifting pump 3 is fixedly installed in the water lifting pit 2. The upper water inlet pipe 5 and the lower water inlet pipe 6 are connected to the water outlet 3-1 of the water lifting pump through a three-way flow dividing valve 4.
[0027] In this embodiment, both the upper water inlet pipe 5 and the lower water inlet pipe 6 are installed below the water surface 1-2 of the rice field on the side of the rice field ridge 1-1. The upper water inlet pipe 5 and the water lifting pump 3 are installed in the same rice field 1, and the lower water inlet pipe 6 is installed in the next rice field 1. Through the guiding action of the water lifting pump 3 and the three-way flow dividing valve 4, a circulating water flow between the rice fields 1 and a circulating water flow within the rice field 1 are formed.
[0028] In this embodiment, the upper water inlet pipe 5 and the lower water inlet pipe 6 installed on the same water lifting pump 3 form a right angle, and the upper water inlet pipe 5 and the lower water inlet pipe 6 within the same rice field 1 are parallel to each other.
[0029] In this embodiment, a Venturi injector 7 is installed on the upper water inlet pipe 5 and the lower water inlet pipe 6 at intervals of 1 meter. The air inlet 7-2 of the air duct 7-1 of the Venturi injector is arranged above the water surface 1-2 of the rice field. When the Venturi injector 7 is working, it can suck in air to increase the oxygen content of the water body, effectively improving the dissolved oxygen level of the water body in the rice field aquaculture.
[0030] In this embodiment, the installation directions of the water outlets 7-3 of the Venturi injectors are all at a horizontal 45° angle along the water flow direction of the water inlet pipe to form an inclined jet flow. Through the water flow thrust generated by the Venturi injectors 7 installed on the upper water inlet pipe 5 and the lower water inlet pipe 6, the aquaculture water body in the rice field is pushed to form a circular water flow, preventing the occurrence of "dead water areas" in the aquaculture water body in the rice field.
[0031] Although the specific embodiments of the present invention have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative only and not used to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should all be covered within the scope protected by the claims of the present invention.
