Soil deep fertilizing device capable of preventing fertilizer loss

Abstract

The invention discloses a soil deep fertilizing device capable of preventing fertilizer loss. The soil deep fertilizing device capable of preventing fertilizer loss comprises a bottom plate and a discharging bent tube at the bottom of the bottom plate, wherein a triangular block is welded to the bottom end of the discharging bent tube; a circular hole is formed in a bent position of the discharging bent tube; a spiral conveying rod is arranged in the discharging bent tube; a discharging motor is fixed on a top plate in a fertilizer box through a fixing rack; and the discharging motor is in transmission connection with a bolt conveying rod through a speed reducer. By the discharging bent tube at the bottom of the bottom plate, the discharging bent tube can be inserted into soil through a triangular block when moving through a roller on the bottom plate, then a fertilizer is applied into the soil through the circular hole formed in the discharging bent tube, and fertilizer loss is prevented effectively; and furthermore, by the bolt conveying rod in the discharging bent tube, the fertilizer is conveyed by the spiral conveying rod, the discharging speed is stable, the discharging bent tube cannot be blocked, and therefore, stability of the soil deep fertilizing device is improved effectively.

Description

technical field [0001] The invention relates to the technical field of fertilization devices, in particular to a deep soil fertilization device for preventing fertilizer loss. Background technique [0002] When the soil cannot provide the nutrients needed for crop growth and development, the act of artificially supplementing crops with nutrient elements is called fertilization. Fertilization must consider the soil because: first, only when the soil has insufficient supply of a certain nutrient When fertilization is needed, it is not necessary to apply all the essential elements to the soil, because most of the nutrient elements are in sufficient supply, otherwise it will cause waste and even cause crop poisoning. This point is sometimes overlooked. Second, after the fertilizer is applied to the soil, a series of changes will occur, which will affect the fertilizer effect to varying degrees. If the soil is not considered, it is impossible to talk about real and reasonable fe...

Second, after the fertilizer is applied to the soil, a series of changes will occur, which will affect the fertilizer effect to varying degrees. If the soil is not considered, it is impossible to talk about the real rational fertilization

[0003] However, existing soil fertilization devices have some disadvantages in use. Existing soil fertilization devices generally apply fertilizers on the surface of the soil, resulting in serious loss of fertilizers. Secondly, the feed pipes used for fertilization It is easy to block due to the moisture of the fertilizer, and the feeding speed of the feeding pipe is also unstable, resulting in low quality of fertilization
