Description

Technical Field

[0001] The utility model relates to a precise topdressing device for agricultural planting roots, belonging to the technical field of agricultural planting. Background Art

[0002] There are two main ways for plants to absorb nutrients: one is absorption through the roots, and the other is absorption through the leaves. Root fertilization is to apply nutrient fertilizers into the soil, and the fertilizers dissolve in the soil solution, then come into contact with the roots, and are absorbed and utilized by the capillary roots or root tips of the plants, and then transmitted to the roots, stems, leaves, flowers, and fruits of the crops. Plants absorb nutrients mainly through their roots. According to statistics, 90% of the nutrients absorbed by crops come from absorption, transmission, and redistribution by the roots, while leaf absorption is only an auxiliary role.

[0003] The existing patent number is CN221152009U, which is a precise topdressing device for agricultural planting roots. This device drives the connecting plate to move through the cylinder, and then the slide seat drives the baffle to move through the suspension rod, closing the outlet of the fertilizer box to prevent fertilizer leakage when not in use. At the same time, the fertilizer discharge speed can be adjusted, and the spring action can prevent excessive pressure under the baffle and collision damage to the bottom of the fertilizer box. The double-headed motor drives the screw to rotate and the support plate to make a threaded movement, so that the support plate drives the ramp to slide on the outside of the material channel, thereby changing the distance between the end of the material channel and the fertilizer box. , so that the device can accurately fertilize the roots of crops at different distances from the fertilizer box, but the precise topdressing structure used in this device is a frame type, which cannot accurately guide the fertilizer and is prone to leakage. At the same time, there is no fertilizer guiding structure inside it, which easily causes a large amount of fertilizer to accumulate inside and be difficult to discharge, thereby affecting the smooth discharge of the fertilizer; and the method of this device for discharging and blocking materials by controlling the lifting and lowering of the baffle is not convenient enough, and it is difficult to accurately control the amount of topdressing, which easily causes excessive discharge of fertilizer, which is not conducive to the normal growth of plants.
