As shown in fig. 1 to 9, when the irrigation ditch valve for modern agricultural production in environment protection according to the present invention is used, firstly, the lubricating oil is poured into the third frame 43 through the liquid inlet hole 431, and then flows into the second frame 42 through the fourth through hole 432 and the second through hole 421, and in an initial state, the third through hole 422 is not communicated with the first through hole 411, so that the lubricating oil is stored in the second frame 42, and the floating blocking ring 44 rises along with the rise of the lubricating oil level in the second frame 42 until the floating blocking ring 44 rises to the height of the second through hole 421, so as to block the second through hole 421, so that the rest of the lubricating oil is stored in the third frame 43. When lubricating oil needs to be sprayed on the threaded rod 3, the third frame 43 or the second frame 42 can be manually rotated, then the connecting rope 49 is inclined, the second elastic member 48 is stretched, the second elastic member 48 pulls the sealing positioning rod 47 downwards so as to indirectly pull the extrusion plate 46 downwards, so that the extrusion plate 46 moves downwards, the first elastic member 45 is stretched, further, the elastic coefficient of the second elastic member 48 is greater than that of the first elastic member 45, then the second elastic member 48 is stretched, and the extrusion plate 46 moves downwards, so that the lubricating oil in the second frame 42 can be extruded, because the third through hole 422 is arranged opposite to the first through hole 411, in the process that the second frame 42 rotates relative to the first frame 41, the third through hole 422 is periodically communicated with the first through hole 411, and when the third through hole 422 is communicated with the first through hole 411, the pressing plate 46 moving downwards enables the air pressure below the pressing plate to be increased remarkably, then lubricating oil can flow out rapidly through the third through hole 422 and the first through hole 411 and is sprayed onto the outer wall of the threaded rod 3 rapidly through the spray head 5, so that the purpose of spraying lubricating oil onto the threaded rod 3 is achieved, in the embodiment, four third through holes 422, four first through holes 411 and four spray heads 5 are arranged, so that lubricating oil can be sprayed onto the threaded rod 3 from four directions, the lubricating oil can be sprayed onto the threaded rod 3 more uniformly and efficiently, meanwhile, the second frame body 42 can be sprayed onto the threaded rod 3 comprehensively only by rotating a small angle (such as 45 degrees and not more than 90 degrees at most), the operation is simple, the use is convenient, and the above manner has many advantages that firstly, in the rotating process of the second frame body 42, the sealing positioning rod 47 and the pressing plate 46 are driven to move downwards by the connecting rope 49 and the second elastic member 48, the lubricating oil in the second frame body 42 is automatically pressurized, so that the lubricating oil can be rapidly sprayed when the third through hole 422 and the first through hole 411 are communicated, the spraying efficiency is high, and the operation is simple; secondly, the lubricating oil is sprayed to the threaded rod 3 through the spray head 5, so that oil is saved, the waste of the lubricating oil is reduced, the lubricating area of the threaded rod 3 by the same amount of lubricating oil is increased, and the cost is reduced; thirdly, the floating plug ring 44 can automatically cut off the flow of the lubricating oil when the lubricating oil in the second frame 42 is too much, and when the lubricating oil in the second frame 42 is too little (at this time, the floating plug ring 44 moves downwards to the lower part of the second through hole 421 along with the liquid level), the lubricating oil in the third frame 43 can be automatically supplemented into the second frame 42, so that the automatic degree of automation is high, the structure is simple, the cost is low, and the device is suitable for popularization and application. After spraying, the first elastic member 45 is stretched to pull the pressing plate 46 upwards, so that the pressing plate 46 is reset upwards, then the second elastic member 48 is pulled upwards through the sealing positioning rod 47 to gradually reset, and the second frame body 42 is automatically rotated and reset on the first frame body 41 until the initial state is recovered. In the process of spraying lubricating oil, the threaded rod 3 can also be driven to rotate, so that the threaded rod 3 can be sprayed more comprehensively, and the effect is more ideal.
