[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figures 1 to 6 As shown, in this embodiment, the corn dense planting water-nitrogen coupling irrigation equipment includes a main pipeline 1, a control valve for controlling the on-off of the main pipeline 1 is installed on the main pipeline 1, a plurality of branch pipes 2 are installed in parallel on one side of the main pipeline 1, and a manual valve for controlling the on-off of the branch pipes 2 is installed on each of the plurality of branch pipes 2, a barrel 3 is installed on the main pipeline 1 through a bracket, a transparent area 19 is provided on one side of the barrel 3, a scale bar is added to the transparent area 19, the top of the barrel 3 is open, and a discharge pipe 4 is installed at the bottom of the barrel 3, the discharge pipe 4 is connected to the main pipeline 1, and at the discharge A No. 1 one-way valve is installed at the end of the tube 4 for unidirectionally delivering the medium into the main pipeline 1; a feed pipe 5 is installed at the bottom of one side of the barrel 3, and a No. 2 one-way valve is installed at the end of the feed pipe 5 for unidirectionally introducing the medium into the barrel 3; a piston 6 is installed at the top of the barrel 3 in a sliding seal, and an electric cylinder 7 is installed at the top of the barrel 3 through a bracket, and the output end of the electric cylinder 7 is connected to the upper surface of the piston 6; and an interception mechanism is added to the feed pipe 5, which follows the piston 6, and the active cleaning action is completed by synchronously linking the interception mechanism through the movement of the piston 6.

[0025] like Figure 5 and Figure 6As shown, the interception mechanism includes a No. 1 sleeve 8 detachably connected to the feed pipe 5 through a flange, a filter screen 9 is detachably installed in the No. 1 sleeve 8, a No. 2 sleeve 10 is concentrically arranged at one side of the No. 1 sleeve 8, a ring member 11 is rotatably installed between the No. 1 sleeve 8 and the No. 2 sleeve 10, and slideways matching the ring member 11 are provided on the side walls of the No. 1 sleeve 8 and the No. 2 sleeve 10, and fixed arms 12 are installed on the top and bottom of the side close to the No. 1 sleeve 8 and the No. 2 sleeve 10, and the two ends of the fixed arm 12 are detachably fixedly connected to the No. 1 sleeve 8 and the No. 2 sleeve 10 respectively, and the No. 1 sleeve 8 and the No. 2 sleeve 10 are connected as a whole through the two fixed arms 12, and a scraper 13 is detachably installed in the ring member 11, and the scraper 13 is in contact with the filter screen 9 to complete the cleaning, and an annular flange 14 is added in the No. 1 sleeve 8, and the annular flange 14 is detachably fixed to the filter screen 9 by bolts;

[0026] It should be noted that: when intercepting: by providing an interception mechanism, when the piston 6 moves downward to add fertilizer into the main pipeline 1, the vertical rod 16 is driven to move downward, and the rack 18 is driven to move downward at the same time. Since the rack 18 is meshed with the outer gear ring 15, the downward movement of the rack 18 pushes the outer gear ring 15, the ring 11 and the scraper 13 to complete the follow-up work, and the scraper 13 scrapes the filter 9 to complete the rapid cleaning work, avoiding the problem of filter 9 being blocked. At the same time, when the rack 18 moves upward, the outer gear ring 15, the ring 11 and the scraper 13 can also be linked to complete the rotation, so that the piston 6 can complete the active cleaning of the filter 9 on the path of completing the fertilizer filling and automatic feeding, which greatly reduces the subsequent maintenance difficulty of the staff, and the No. 1 casing 8 and the No. 2 casing 10 are detachably connected through the fixed arm 12, so that the filter 9 can be disassembled and replaced later, reducing the subsequent maintenance workload of the equipment;

[0027] Among them, an outer gear ring 15 is sleeved on the outside of the annular member 11, and a vertical rod 16 is installed on one side of the top of the piston 6. The top of the vertical rod 16 is higher than the top height of the barrel 3, so that the rack 18 can move up and down stably to avoid interference. A cross arm 17 is installed on one side of the barrel 3, and a rack 18 is slidingly restricted on the cross arm 17. The rack 18 is meshed and connected with the outer gear ring 15, and the top of the rack 18 is detachably fixedly connected to the vertical rod 16. The meshing of the rack 18 and the outer gear ring 15 drives the annular member 11 and the scraper 13 to complete the follow-up rotation.

[0028] The utility model provides a corn dense planting water-nitrogen coupling irrigation device, and the specific working principle is as follows: first, the feed pipe 5 is connected with the external fertilizer to ensure the sufficient supply of fertilizer. At the same time, since the feed pipe 5 and the discharge pipe 4 are respectively installed with a second check valve and a first check valve, the fertilizer is introduced into the barrel 3 in a single direction, and is also sent into the main pipeline 1 in a single direction to mix with the irrigation water. Subsequently, the fertilizer and the irrigation water are sent to the vicinity of the corn plants through the main pipeline 1 through the pre-buried pipeline to complete the irrigation treatment, thereby completing the rapid irrigation of the fertilizer, and at the same time The irrigation amount can be controlled at the same time. In specific operation, it is only necessary to start the electric cylinder 7 to drive the piston 6 to move downward in the barrel 3, so that the fertilizer stored in the barrel 3 is pushed into the main pipeline 1 through the discharge pipe 4 to complete the subsequent irrigation work. Subsequently, the electric cylinder 7 drives the piston 6 to move upward and reset, and the piston 6 moves upward accordingly. At this time, the external fertilizer is unidirectionally added into the barrel 3 through the feed pipe 5 to complete the automatic feeding. Therefore, under the up and down reciprocating motion of the piston 6, the automatic filling and automatic feeding of the fertilizer can be completed, which greatly reduces the difficulty of manual irrigation operation;

[0029] At the same time, an interception mechanism is added, which can intercept unmelted particles in the fertilizer to avoid accumulation and poor circulation in the pipeline. The interception mechanism is also linked with the piston 6. When the piston 6 moves up and down, the scraper 13 in the interception mechanism is driven to complete follow-up scraping and cleaning, avoiding blockage of the interception mechanism and ensuring stable irrigation work.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
