Ditcher for eliminating red earth by confrontation of red earth by means of magnetism and friction heat

Abstract

The invention discloses a ditcher for eliminating red earth by confrontation of red earth by means of magnetism and friction heat. The ditcher structurally comprises an earth retaining hood, a mounting rack, a hydraulic cylinder, a ditching plate, ditching knives, cutterheads and a transmission. The cutterheads are mounted at two ends of the bottom of the transmission, and the ditching knives aremechanically connected to the cutterheads. Compared with the prior art, the ditcher disclosed by the invention has the beneficial effects that as red earth contains ferrum and magnesium parent materials, attached red earth is driven to move as an electromagnet is electrified by means of the magnetic principle, so that the moving red earth and the splashing red earth form confrontation during ditching, and therefore, the red earth falls off while the attached amount of the red earth can be reduced, and ditching is facilitated further; in addition, the viscidity of the red earth is reduced as the red earth and a matrix friction to generate heat, so that the red earth is prevented from being solidified; the ditcher is demagnetized by cutting off the electromagnet, so that the red earth can beeliminated quickly.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a ditch opener which utilizes magnetism and frictional heat to clear red soil against each other. Background technique [0002] Citrus is a precious fruit for human beings. It has a wide range of adaptability to the soil. It can grow with a pH value of 4.5-8, and the most suitable pH value is 5.5-6.5. The pH value of red soil is 5.5-6.0, so red soil is suitable for planting For the good soil of citrus, in order to better develop the root system of citrus, it is necessary to ditch the soil before planting citrus. In order to prevent the soil from splashing around, the existing ditching machines are equipped with fenders above the ditching wheels. As far as red soil is concerned, due to the imperfection of the existing ditching machine technology in ditching, it has the following defects: [0003] 1) When ditching, the red soil will be thrown out by the centrifugal ...

AI Technical Summary

Problems solved by technology

[0003] 1) When ditching, the red soil will be thrown out by the centrifugal force of the ditching wheel. Due to the inertia, the red soil will continue to splash towards the fender. There is a certain pressure on the fender, which will make the red soil adhere to the inner wall of the fender, and the amount of red soil attached to the inner wall of the fender is proportional to the ditching time, so that the distance between the fender and the ditching wheel becomes smaller , so that the ditching wheel is subject to certain resistance during ditching, which is not conducive to ditching;

[0004] 2) Since the fender is fixed and located above the ditching wheel, and the red soil is attached to the inner wall of the fender, it is difficult and cumbersome to remove the red soil. The red soil on the inner wall is removed. Once the red soil is solidified, it is difficult to remove it from the fender
