[0002] The integrated water and fertilizer automatic irrigation equipment is a new type of agricultural irrigation and fertilization technology. It mixes fertilizer and water in a fixed ratio and delivers them to the roots of crops in a quantitative, regular and uniform manner through a pressure system in the form of drip irrigation or sprinkler irrigation. This equipment greatly improves the absorption efficiency of crops for water and fertilizer, saves water and fertilizer resources, and reduces energy consumption in agricultural production.

[0003] In order to increase the spraying range of the sprinkler, the existing integrated water and fertilizer automatic irrigation equipment is equipped with a related structure so that the sprinkler can swing left and right, so that crops can be irrigated over a large range, reducing the irrigation time. Because the rows of different crops are planted differently, the spacing between them will also be different, which results in the sprinkler of the integrated water and fertilizer automatic irrigation equipment not being able to spray crops with larger row spacing, affecting the irrigation effect. For crops with smaller row spacing, water and fertilizer will be sprayed to the gap between two rows of crops, resulting in a waste of water and fertilizer. Utility Model Content

[0025] Combine the following Figure 1-Figure 3 The utility model is described in detail.

[0026] Example

[0027] A water-fertilizer integrated automatic irrigation device comprises a base plate 3, a liquid storage tank 15 is arranged on the base plate 3, the liquid storage tank 15 is connected to a liquid discharge pipe 5, the liquid discharge pipe 5 is connected to a delivery pump 6, the delivery pump 6 is connected to a hose 12, the hose 12 is connected to a nozzle 14, a sleeve 11 is vertically rotatably arranged on the base plate 3, a movable rod 13 fixedly connected to the nozzle 14 is movably arranged in the sleeve 11, a locking mechanism for limiting the movement of the movable rod 13 is arranged on the sleeve 11, a torsion spring is arranged at the rotation position of the sleeve 11, and a driving mechanism for driving the sleeve 11 to rotate intermittently is arranged on the base plate 3.

[0028] The water-fertilizer solution in the liquid storage tank 15 is transported by the delivery pump 6 and finally sprayed from the nozzle 14; the nozzle 14 deflects to one side under the action of the torsion spring, and the driving mechanism drives the sleeve 11 to rotate, so that the nozzle 14 deflects to the other side. During the rotation of the sleeve 11, the torsion spring is twisted and deformed, and then the driving mechanism does not drive the sleeve 11 to rotate. The sleeve 11 returns to the initial position under the elastic action of the torsion spring, thereby realizing the reciprocating swing of the nozzle 14, that is, increasing the spraying and irrigation range of the nozzle 14. After the extended length of the movable rod 13 is adjusted, the position of the movable rod 13 is fixed by a locking mechanism. The extended length of the movable rod 13 affects the height position of the nozzle 14. The water-fertilizer solution sprayed by the nozzle 14 moves in a parabolic trajectory. Therefore, the higher the height of the nozzle 14, the larger the spraying range. Therefore, the spraying and irrigation range of the nozzle 14 can be adjusted by adjusting the extended length of the movable rod 13. The "automatic" in this application means automatic spraying of water and fertilizer. Compared with traditional manual sprayer pesticide machines, this application eliminates the process of manual pressurization and is more convenient to use.

[0029] The driving mechanism includes a gear 9 fixedly mounted on the sleeve 11 and a half gear 8 meshing with the gear 9, and the half gear 8 is connected to the first motor 7. The first motor 7 drives the half gear 8 to rotate, and after the half gear 8 meshes with the gear 9, it drives the sleeve 11 to rotate. When the half gear 8 rotates to the toothless part, the half gear 8 is disengaged from the gear 9, and the gear 9 and the sleeve 11 rotate back to the original position under the action of the torsion spring.

[0030] A protective cover 10 is fixedly arranged on the bottom plate 3 and covers the gear 9, the half gear 8 and the first motor 7, and the sleeve 11 is rotatably connected to the protective cover 10. The protective cover 10 protects the gear 9, the half gear 8 and the first motor 7 to prevent the water fertilizer solution from dripping on the gear 9, the half gear 8 and the rotating part of the sleeve 11, causing them to rust and affect normal rotation. The protective cover 10 can also support the sleeve 11 and increase the rotation stability of the sleeve 11.

[0031] The locking mechanism includes a latch 24 that movably penetrates the sleeve 11 transversely, and a plurality of transverse through holes 25 are provided on the movable rod 13 along the length direction. The latch 24 movably penetrates the sleeve 11 and the through holes 25 on the movable rod 13, thereby limiting the position of the movable rod 13 and preventing the movable rod 13 from moving. The locking mechanism can also be a fixed knob screw, which threads through the sleeve 11 and abuts against the movable rod 13 to fix the movable rod 13.

[0032] The liquid storage tank 15 is provided with a water injection port 20 and a feed hopper 22, a solenoid valve 4 is provided in the liquid discharge pipe 5, and a second motor 21 is provided on the top of the liquid storage tank 15. The second motor 21 is connected to a rotating shaft 18 that vertically rotates and penetrates the liquid storage tank 15, and a stirring rod 19 is connected to the rotating shaft 18. Fertilizer enters the liquid storage tank 15 from the feed hopper 22, and water enters the liquid storage tank 15 from the water injection port 20; the second motor 21 drives the rotating shaft 18 and the stirring rod 19 to rotate so as to stir the fertilizer and water, so that the fertilizer is melted into the water to form a water-fertilizer solution; after the stirring is completed, the solenoid valve 4 is opened and the delivery pump 6 is started to perform the spraying and irrigation operation.

[0033] Two crushing rollers 23 are rotatably arranged in the feed hopper 22. The crushing rollers 23 are connected to a driving motor (not shown in the figure), and the crushing rollers 23 crush the fertilizer in the feed hopper 22 so that it can be quickly dissolved in water.

[0034] The stirring rod 19 is connected with a scraper 17 in contact with the bottom and side walls of the liquid storage tank 15. The scraper 17 can clean the impurities attached to the bottom and side walls of the liquid storage tank 15, reducing the difficulty of subsequent cleaning.

[0035] The side wall of the liquid storage tank 15 is provided with a glass viewing window 16. The glass viewing window 16 can facilitate the operator to check the content of the water-fertilizer solution and the water content when the water-fertilizer solution is configured.

[0036] Wheels 2 are arranged at the bottom of the base plate 3, and handrails 1 are installed on the base plate 3. The operator can push the entire device to move in the cultivated land through the handrails 1. The power source used by the electrical appliance in this application is a battery (not shown in the figure).

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
