Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer spreaders, in particular to a fertilizer spreader with a backwashing function. Background Art

[0002] Fertilizer applicator is also called integrated water and fertilizer machine; integrated water and fertilizer technology is a new agricultural technology that integrates irrigation and fertilization. Integrated water and fertilizer is to use a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type, and mix the fertilizer liquid with irrigation water through a controllable pipeline system to supply water and fertilizer. After the water and fertilizer are mixed, sprinkler irrigation or drip irrigation is formed through pipes, spray guns or nozzles, and sprayed evenly, regularly and quantitatively on the crop development and growth area, so that the soil in the main development and growth area always remains loose and has an appropriate water content. At the same time, according to the fertilizer requirements of different crops, the soil environment and nutrient content, and the fertilizer requirements, the needs of different growth periods are designed, and water and nutrients are provided to crops directly in a regular and quantitative manner in proportion.

[0003] At present, a Chinese patent with publication number CN219577834U and publication date August 25, 2023 discloses a precision water-fertilizer integrated machine, including three mixing tanks, a water pump and a fertilizer pump, the water outlet of the water pump is fixedly connected to a first water inlet pipe, the rear ends of the three mixing tanks are fixedly connected to a feed pipe, the front ends of the three mixing tanks are fixedly connected to a second water inlet pipe, the front ends of the second water inlet pipes are through-connected with the first water inlet pipe, the lower parts of the front ends of the three mixing tanks are fixedly connected to a first fertilizer suction pipe, the front ends of the first fertilizer suction pipes are through-connected with the second fertilizer suction pipe, and one side of the second fertilizer suction pipe is fixedly connected to the feed port of the fertilizer pump; the discharge port of the fertilizer pump is fixedly connected to a first fertilizer discharge pipe, the front end of the first fertilizer discharge pipe is fixedly connected to several second fertilizer discharge pipes, the front end of the second fertilizer discharge pipe is fixedly connected to a third fertilizer discharge pipe, the outside of the front end of the first fertilizer discharge pipe is fixedly connected to three agricultural PH sensors, and the middle part of the upper surface of the mixing tank is rotatably connected to a servo motor.

[0004] The mixing tank is a fertilizer tank, which is usually placed on the ground. However, since the integrated water and fertilizer machine often needs to be installed on the land where crops grow, and the land full of loose soil is often not flat, the fertilizer tank cannot be placed flat, which affects the pipe connection of the fertilizer tank. At the same time, when the fertilizer tank is stirred by the servo motor, the vibration of the fertilizer tank will also cause the fertilizer tank to be unstable on the ground. Utility Model Content
