Deep-layer soil fertilizing device for directly promoting soil remediation

Abstract

The invention discloses a deep-layer soil fertilizing device for directly promoting soil remediation. The device comprises a top plate and an inner-layer pipe; the outer wall of the top of the top plate is fixedly provided with a mounting plate through bolts, the outer wall of the top of the mounting plate is fixedly provided with a controller and a switch through bolts, the outer wall of the topof the top plate is fixedly provided with a first motor through bolts, a gear disc is welded to an output shaft of the first motor, a hollow threaded rod is in threaded connection with the center of the outer wall of the top of the top plate, the outer wall of one side of the threaded rod is provided with a thread, and the specifications of the thread are matched with those of the gear disc. According to the device, the pressure of a drill bit on soil per unit area is increased through a conical arc-surface structure, staggered teeth of different specifications can crush the soil at differentlevel heights around the drill bit, at the same rotation speed, the rotation speed of the inner-layer pipe gets slow, so that the inner-layer pipe and a threaded pipe are misaligned, through holes areexposed, and fertilizer liquid can be splashed out through the through holes in the rotation process.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a deep soil fertilization device for directly propelling soil remediation. Background technique [0002] In recent years, my country's soil pollution has become more and more serious. Soil pollution refers to soil pollution caused by the organic matter entering the soil exceeding the self-purification capacity of the soil. At present, with the rapid development of modern industry and agriculture, the large-scale application of chemical fertilizers and pesticides and the discharge of chemical, pesticide, pharmaceutical production and other enterprises have led to the continuous deterioration of soil pollution. Soil organic pollutants are mostly volatile and semi-volatile compound pollutants. These pollutants are constantly migrating and transforming in the soil. They can not only enter the food chain through agricultural production, but also enter the human body through b...
