Abstract

The invention relates to an intelligent layered controllable precision deep scarification fertilization device, comprising a frame fixing device, a fertilizer ejecting device, a layered fertilization deep scarification device, a hydraulic driving system and a control system, wherein the fertilizer ejecting device is used for supplying a fertilizer to ensure the growth conditions of crops; the layered fertilization deep scarification device is used for deeply scarifying soil and applying the fertilizer to different soil layers; the hydraulic driving system changes the rotating speed of a fertilizer ejecting shaft of the fertilizer ejecting device by controlling the rotating speed of a hydraulic motor, and then changes the fertilizer ejecting speed; and the control system realizes fertilizer compensation by controlling the rotating speed of a hydraulic motor in the hydraulic driving system. A few of fertilizer ejecting pipes of a fertilization shovel separately reach different soil layers; each fertilizer ejecting branch is provided with an electromagnetic proportional velocity regulating valve, a hydraulic motor and an outer grooved wheel fertilizer ejector, so that layered control can be realized, the fertilization precision is higher, and the controllability is stronger; and the device realizes 'single pipe single control', layered control of the fertilization amount and intelligent precision deep fertilization, thereby improving the utilization rate of the fertilizer, relieving the labor intensity and improving the working efficiency.

Description

[0001] 1. Technical field [0002] The invention relates to an intelligent layered and controllable precision subsoiling fertilization device. [0003] 2. Background technology [0004] Precision fertilization technology is an important part of precision agricultural technology research, and layered precision fertilization device is a key component of precision fertilization seeder. With the development of precision agriculture and intelligent agriculture, subsoiling and full-layer fertilization can break the hard plow bottom layer and open up the infiltration channels of rainwater and irrigation water; fertilizer can also be applied to the soil at one time to ensure that the maize There is enough fertilizer in the whole process of growth, which breaks the traditional farming mode, does not need topdressing, and reduces the labor required for topdressing; at the same time, it also solves the problems of nitrogen volatilization, phosphorus not moving down, and premature aging of...
