Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, and more specifically to a crop irrigation device. Background Art

[0002] Agricultural irrigation mainly refers to the irrigation work in agricultural cultivation areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. When planting cotton, it is sometimes necessary to improve the soil environment through fertilizers. The fertilizers are dissolved in water and then irrigated on the roots of crops to increase the elements needed for crop growth.

[0003] After searching, the existing patent (publication number: CN219019558U) discloses a crop irrigation device. During use, the frame is driven by wheels to move in the gap between fields, and the frame is kept stable by handles to prevent the frame from tipping over. Fertilizer is added to the water tank, and the water and fertilizer inside the water tank are pumped by a water pump and introduced into the spray pipe. The roots of cotton plants are fertilized by the spray pipe, so that the water source is maximized, the fertilizer in the water is irrigated at the roots, and the fertilizer is prevented from adhering to the surface of the branches and leaves of crops, which will not cause waste. However, the inventor discovered the following problems in the prior art during the process of realizing the utility model: the above-mentioned crop irrigation device is a vehicle-type structure, which cannot be used inside a field with small gaps between crops. When fertilizing inside a field with small gaps, a backpack-type irrigation and fertilization method is often used, that is, the worker uses a backpack to carry a water tank on his back, and then holds a nozzle in one hand. A delivery pipe is provided at one end of the nozzle. The liquid medicine inside the water tank enters the nozzle through the delivery pipe, and then is sprayed onto the crops from the nozzle at the end of the nozzle, thereby achieving the purpose of irrigating and fertilizing the crops. For this irrigation method, when the worker holds the nozzle and brings the nozzle close to the roots of the crops, it is blocked by the dense branches and leaves of the crops. When the user holds the nozzle and moves, the nozzle often collides with the crops or the ground. There are tiny water outlet holes on the surface of the nozzle. When the nozzle is collided, the nozzle holes are easily blocked and the nozzle is damaged, making it difficult to complete the irrigation operation smoothly.

[0004] In view of this, the utility model proposes a crop irrigation device to solve this problem. Utility Model Content

[0013] Furthermore, a support pad is provided at the bottom of the water tank. There are four support pads, which are arranged in a rectangular array at the four corners of the bottom of the water tank. By providing the support pads, it is convenient to maintain the balance and stability of the water tank when the water tank is placed on the ground.

[0014] Furthermore, a sealing rubber pad is adhered to one side of the baffle plate close to the spray hole; by providing the sealing rubber pad, the blocking effect of the baffle plate on the spray head can be improved, thereby preventing the liquid from dripping from the spray hole during the movement of the handle.

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model uses a nylon strap to wear the water tank, and holds the handle. During the movement, the operator directs the nozzle of the handle toward the root of the crop, and then presses the pressure handle.
