Description

Technical Field

[0001] The utility model relates to the field of alternate irrigation, in particular to a drip irrigation water-fertilizer alternate irrigation device. Background Art

[0002] Agricultural irrigation is a technical measure to replenish the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops need to be irrigated and fertilized to ensure the water and nutrients needed by crops. In areas where water resources are scarce, when irrigating and fertilizing crops, excessive water irrigation can easily lead to water evaporation and waste, and excessive fertilization can make it difficult for crops to fully absorb, resulting in nutrient loss.

[0003] The current drip irrigation device that uses alternating water and fertilizer for irrigation is difficult to reasonably supply water for drip irrigation and fertilization. A large amount of nutrient solution is wasted when drip irrigation is performed at one time, making it difficult to fully utilize the nutrient solution. The nutrient solution is easily separated after being left for a long time, making it difficult to drip irrigate the nutrient solution evenly. The small drip irrigation area is not conducive to the crops fully absorbing the nutrients in the fertilizer. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the utility model provides a drip irrigation water-fertilizer alternating irrigation device, which can reasonably supply water for drip irrigation and fertilization, so that the nutrient solution can be more fully utilized, and the nutrient solution can be prevented from being separated for a long time, so that the nutrient solution can be drip irrigated more evenly, and the nutrient solution drip irrigation area is larger to facilitate the crops to fully absorb the fertilizer.

[0005] A device for alternate irrigation of water and fertilizer for drip irrigation comprises a water tank, a nutrient solution tank, a valve body, a baffle, a reset spring, a hose and a drip irrigation head. A nutrient solution tank is installed on one side of the water tank. Valve bodies are installed at the liquid outlets of the water tank and the nutrient solution tank. Baffles are slidably connected to the middle of the two valve bodies. Drain holes are opened on the baffles. A reset spring is connected between each baffle and the valve body. A hose is connected to the bottom of each valve body. Each valve body is connected to the hose. A drip irrigation head is connected to the bottom of each hose. An alternate irrigation mechanism is installed on the water tank and the nutrient solution tank. The alternate irrigation mechanism is used for drip irrigation and fertilization respectively, so as to avoid waste of more nutrient solution caused by one-time drip irrigation, so that the nutrient solution can be more fully utilized.

[0006] Furthermore, the alternating irrigation mechanism includes a push rod 1, a push rod 2, a servo motor, a rotating shaft, a rotating plate, a bevel cam and a protrusion. The push rod 1 is fixedly connected to the baffle below the water tank, the push rod 2 is fixedly connected to the baffle below the nutrient solution tank, a servo motor is installed at the bottom of the water tank and the nutrient solution tank, the output shaft of the servo motor is connected to the rotating shaft, the rotating plate is fixedly connected to the rotating shaft, an bevel cam is installed on one side of the rotating plate, the bevel cam has an opening, the push rod 1 is in contact with one side of the rotating plate, the contact point of the push rod 1 and the rotating plate is located at the opening of the bevel cam, a protrusion is installed on the other side of the rotating plate, and the push rod 2 is in contact with the other side of the rotating plate.

[0007] Furthermore, it also includes a stirring roller, a driving wheel, a driven wheel and a transmission belt. The stirring roller is rotatably connected to the nutrient solution tank, the driving wheel is installed on the rotating shaft, the driven wheel is installed on the stirring roller, and a transmission belt is wound around the driving wheel and the driven wheel.

[0008] Furthermore, it also includes a rotating disk, a support frame, a movable frame and a straight groove rod. The rotating disk is installed on the rotating shaft, the support frame is installed at the bottom of the nutrient solution tank, the movable frame is slidably connected to the support frame, one end of the movable frame is slidably connected to the drip irrigation head, and the other end of the movable frame is fixedly connected to the straight groove rod, which is slidably connected to the rotating disk.

[0009] Furthermore, the movable frame is located below the nutrient solution tank, and the movable frame is used to push the dropper head below the nutrient solution tank.

[0010] The beneficial effect is that the baffle is driven to move alternately by the inclined cam and the convex block, so that the equipment can drip water for a long time and drip a small amount of nutrient solution in a short time, thereby completing the alternating irrigation of water and fertilizer, and can drip the nutrient solution reasonably, avoiding the waste of a large amount of nutrient solution caused by one-time drip irrigation, so that the nutrient solution can be more fully utilized.

[0011] The rotating shaft and the driving wheel drive the driven wheel and the stirring roller to rotate together through the transmission belt. The stirring roller stirs the nutrient solution in the nutrient solution tank to prevent the nutrient solution in the nutrient solution tank from separating due to long-term storage, so that the nutrient solution can be drip-irrigated more evenly, thereby improving the fertilization effect.
