A deep root fertilizer applicator for agricultural planting

Abstract

The invention discloses an agricultural planting deep-root fertilizer which discloses a fertilizer which rotates the soil layer through the outer helical blade, and pushes the fertilizer into the soil through the relative rotation between the guide pipe and the leaf plate. Single-person operation, no need to fill soil, effectively improving the efficiency of fertilization operations. It is characterized in that one end of the guide pipe is placed at the bottom of the hopper and communicated with the hopper, the diameter of the bottom of the hopper gradually decreases, the diameter of the guide pipe gradually increases from the other end to one end, and the diameter of the other end of the guide pipe is the guide One-half of the diameter of one end of the tube, the rotary block is rotatably placed on the other end of the guide tube, the rotary block is an arc-shaped cover structure, the middle part of the rotary block extends to the inside of the guide tube to form a rotating shaft, a plurality of leaf plates, etc. The distance is placed on the rotating shaft, and there is a gap between the leaf plate and the inner wall of the guide tube. There is a blanking hole on the guide tube, which corresponds to the page plate. The diameter of the blanking hole gradually decreases from the inside to the outside. , the helical blade is placed on the outer wall of the guide tube.

Description

technical field [0001] The invention relates to a deep root fertilizer for agricultural planting, which relates to a fertilizer for quantitatively fertilizing crops when fertilizing the crops at the edge of the agricultural planting field, and belongs to the field of agricultural planting. It particularly relates to a fertilizer applicator which performs rotary cutting on the soil layer through the outer helical blade, and pushes the fertilizer into the soil through the relative rotation between the guide pipe and the leaf plate. Background technique [0002] At present, during agricultural planting, it is necessary to apply fertilizer to the crops to ensure the nutrition of the crops. The current fertilization method is to directly sprinkle the fertilizer on the soil surface of the field ridge, and cannot directly reach the root of the crop.

Problems solved by technology

[0002] At present, during agricultural planting, it is necessary to apply fertilizer to the crops to ensure the nutrition of the crops. The current fertilization method is to directly sprinkle the fertilizer on the soil surface of the field ridge, and cannot directly reach the root of the crop. Only when it rains, the fertilizer penetrates into the soil through the rainwater Deep, but because a lot of rainwater will be discharged along the ditch of the field ridge, especially the crops near the outside, the rainwater drainage will be large, and the fertilizer will be taken away, which will easily lead to insufficient nutrition at the root position, and finally lead to ineffective fertilization. Therefore, it is necessary to Manually replenish fertilizers to the crops at the edge, and send the fertilizer directly into the soil. The traditional method is to use a hoe to remove the soil layer, send the fertilizer in and then bury it. It requires two people to work together. Large, and the amount of fertilizer fed during operation cannot be controlled. There are also fertilizer applicators that can only fertilize in soft soil, but cannot penetrate dry and hard soil layers, and the amount of fertilizer applied cannot be controlled.

[0003] Publication number CN105052328A discloses a root fertilizer applicator, which includes a fertilizer applicator body. The fertilizer applicator body includes a fertilization cylinder, a feed pipe connected with the fertilization cylinder, and a perforating rod that passes through the fertilization cylinder from top to bottom. The perforation rod is fixed on the The elastic part in the fertilization tube is tightened, the piston is fixed on the punching rod, the side wall of the fertilization tube is provided with a cavity, and the cavity is provided with a pressure plate that is clamped with the piston near the end of the feed pipe, and a torsion spring that is connected to the pressure plate is provided under the pressure plate. With the connected adjustment plate, the invention can only apply fertilizer to the corresponding depth position, and cannot gradually carry out fertilizer layout along the depth, and the fertilizer application is concentrated
