Agricultural-planting deep root fertilizing device

Abstract

The invention discloses an agricultural-planting deep root fertilizing device. According to the fertilizing device, rotary cutting is carried out on a soil layer through an spiral blade at the outer side, and a fertilizer is pushed into soil through relative rotation between a guide pipe and blade plates. The fertilizing device can be operated by a single person, soil filling is not needed, and fertilization operation efficiency is effectively improved. The fertilizing device is characterized in that one end of the guide pipe is arranged at the bottom of a hopper and communicates with the hopper, the diameter of the bottom of the hopper is gradually reduced, the diameter of the guide pipe is gradually increased from the other end to one end, and the diameter of the other end of the guide pipe is one half of the diameter of one end of the guide pipe; a rotating block is rotatably arranged at the other end of the guide pipe, the rotating block is of an arc-shaped cover structure, the middle of the rotating block extends towards the inner part of the guide pipe to form a rotating shaft, and a plurality of the blade plates are arranged on the rotating shaft at equal intervals; a gap isformed between the blade plate and the inner wall of the guide pipe, a blanking hole is formed in the guide pipe and corresponds to the bade plates, and the diameter of the blanking hole is graduallyreduced from inside to outside; and the spiral blade is arranged on the outer wall of the guide pipe.

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
