For ordinary skilled persons in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances. The embodiments will be described below according to the overall structure of the utility model.

[0026] Referring to Figures 1-2 , in the utility model embodiment, a kind of saline-alkali soil winter wheat quantitative nitrogen application drip irrigation device, comprising: support frame 1, one end of support frame 1 is fixedly connected with mixing barrel 2, mixing barrel 2 is provided with discharging assembly 3, mixing barrel 2 is provided with nitrogen adding assembly 4, one end of mounting bracket 31 is fixedly connected with collecting hopper 5, and collecting hopper 5 collecting mouth is arranged below discharge port 22, and one end of collecting hopper 5 is connected with drip irrigation pipe 6.

[0027] Referring to Figure 3 , water inlet 21 is throughly provided in the top of mixing barrel 2, discharge port 22 is throughly provided in the bottom of mixing barrel 2, feed inlet 23 is throughly provided in the side end of mixing barrel 2, water storage plate 24 is rotatably arranged in mixing barrel 2, mixing plate 25 is rotatably arranged in mixing barrel 2, and mixing plate 25 is arranged below water storage plate 24 and above discharge port 22, and magnetic block one 26 is embedded in the side end of mixing barrel 2, and magnetic block one 26 is magnetically connected with the end surface of water storage plate 24, water storage plate 24 is composed of a group of straight rods and four groups of straight plates, the straight rod in water storage plate 24 penetrates through mixing barrel 2 and is rotatably connected with mixing barrel 2, and the four groups of straight plates in water storage plate 24 are symmetrically distributed on the outer side of straight rod and are distributed at ninety degrees, and the straight rod and straight plate in mixing plate 25 are also composed of a group of straight rods and four groups of straight plates, the size of the straight rod and straight plate in mixing plate 25 is smaller than that of the straight rod and straight plate in water storage plate 24, the straight rod in mixing plate 25 penetrates through mixing barrel 2 and is rotatably connected with mixing barrel 2, and the four groups of straight plates in mixing plate 25 are symmetrically distributed on the outer side of straight rod and are distributed at ninety degrees, the cross section of mixing barrel 2 is drop-shaped, the top end is circular, and the bottom end is triangular, and the straight plate in water storage plate 24 abuts against the circular top end of mixing barrel 2.

[0028] With the above scheme: the cross section of the mixing barrel 2 is designed in the shape of a water droplet, the top end is circular, and the bottom end is triangular. This unique shape fits well with the water storage plate 24. During the water storage stage, the circular top end can make the straight plates of the water storage plate 24 tightly abut against it, ensuring that water can be stably stored between the two groups of straight plates of the water storage plate 24. In the initial stage of rotation of the water storage plate 24, it is tightly attached to the upper end of the barrel body, effectively preventing water leakage, and providing stable preliminary conditions for subsequent mixing and discharging links.

[0029] With reference to Figures 4-5 , the discharging assembly 3 includes a mounting frame 31 fixedly connected to the outer side of the mixing barrel 2, a baffle 32 slidingly inserted into the mounting frame 31, a magnetic block two 33 embedded on the inner side of the baffle 32 and magnetically connected to the end face of the water storage plate 24, a spring one 34 fixedly connected to the top end of the baffle 32, one end of the spring one 34 fixedly connected to the inner top end of the mounting frame 31, and a discharge port 35 throughly formed on one end of the baffle 32. The spring one 34 is provided with multiple groups and uniformly distributed on the top end of the baffle 32. The baffle 32 is made of flexible material and can be bent according to the shape of the mounting frame 31. The mounting frame 31 is in the shape of J.

[0030] With the above scheme: through the magnetic linkage mechanism between the baffle 32 and the water storage plate 24, the discharging time is controlled. Initially, the straight plates of the water storage plate 24 are magnetically connected to the magnetic block one 26, and water accumulates between the straight plates of the water storage plate 24. When the water volume increases to a certain extent, the water storage plate 24 rotates, and the straight plates are magnetically connected to the magnetic block two 33, thereby driving the baffle 32 to slide downward in the mounting frame 31. This makes the discharge port 35 accurately move below the discharging port 22, opening the communication channel between the mixing barrel 2, the collecting hopper 5 and the drip irrigation pipe 6. When the water storage plate 24 rotates to a specific position, the straight plates are separated from the barrel wall, the baffle 32 no longer rotates and is reset under the action of the spring one 34, timely closing the channel, accurately controlling the discharging time, and ensuring that the amount of mixed solution discharged each time meets the quantitative nitrogen application requirement.

[0031] With reference to Figures 6-7 , the nitrogen adding assembly 4 includes a storage barrel 41 fixedly connected to the outer side of the mixing barrel 2, a feeding port 42 throughly formed on one end of the storage barrel 41, the feeding port 42 in communication with the feeding port 23, a sleeve 43 fixedly connected in the feeding port 42, a closing plate 44 slidingly inserted into the sleeve 43, a spring two 45 fixedly connected to one end of the closing plate 44, one end of the spring two 45 fixedly connected to the inner wall of the sleeve 43, a push plate 46 fixedly connected to the other end of the closing plate 44, and multiple groups of the spring two 45 uniformly distributed on one end of the closing plate 44. The storage barrel 41 is in the shape of J. When the water storage plate 24 rotates, it abuts against the push plate 46, thereby pushing the closing plate 44 to insert into the sleeve 43. When inserted for a distance, the push plate 46 is separated from the rotation track of the water storage plate 24 and no longer abuts against the push plate 46.

[0032] With the above scheme: nitrogen assembly 4 controls the addition of nitrogen fertilizer by the rotation of water storage plate 24. When the water storage plate 24 rotates, the front straight plate will abut against the push plate 46, pushing the closing plate 44 to insert into the sleeve 43 against the elastic force of the spring 45, opening the filling port 42, and making the nitrogen fertilizer in the storage barrel 41 fall into the bottom of the mixing barrel 2 due to gravity. When the push plate 46 is out of the rotation track of the water storage plate 24, the closing plate 44 is reset under the action of the spring 45 to block the filling port 42. This process is closely related to the rotation of the water storage plate 24, ensuring that the nitrogen fertilizer is added to the mixing barrel 2 at the right time, achieving precise quantitative addition.
