Furrowing and ridging device for saline and alkaline land

Abstract

The invention discloses a furrowing and ridging device for a saline and alkaline land. The furrowing and ridging device for the saline and alkaline land is mounted at the rear of a tractor and comprises a furrowing rack, wherein a connecting rack is arranged at the front end of the furrowing rack; a rotary tillage shaft is rotatably arranged below the front portion of the furrowing rack; rotary tillage knives are distributed on the rotary tillage shaft; the rotary tillage knives positioned at the two ends of the rotary tillage shaft are oppositely arranged obliquely; a speed-changing box is arranged at the front of the furrowing rack; an outputting end of a speed changing box is connected with the rotary tillage shaft; two furrowing plates are arranged below the rear of the furrowing rack;the rear ends of the two furrowing plates are oppositely and obliquely arranged towards the inner sides; the distance between the upper portions of the rear ends of the two furrowing plates is smaller than the distance between the lower portions of the rear ends of the two furrowing plates; a protective cover is arranged on the furrowing rack and is positioned above the rotary tillage knives; therear end of the protective cover is positioned on the inner sides of the front ends of the two furrowing plates; and the two sides of the protective cover are bent to the outwards and lower direction. The furrowing and ridging device for the saline and alkaline land is convenient to operate, and the furrowing and ridging efficiency of the saline and alkaline land is high.

Description

Technical field [0001] The invention relates to the field of agricultural equipment, in particular to a bordering and ridging device for saline-alkali soils. Background technique [0002] In agricultural production, the traditional method of bordering and ridging is mainly that operators use tools such as shovels to manually border and ridge. This method of bordering and ridging requires heavy manual labor and low efficiency, especially on saline-alkali land. During the ridge operation, the soil structure of saline-alkali soil is damaged, the phenomenon of compaction is more serious, the surface is hard, the artificial ridge and ridge is more difficult, the ridge is uneven, and cannot meet the requirements, and the efficiency of the ridge and ridge in saline-alkali soil is low. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a saline-alkali soil bordering and ridging device with convenient operation and high efficiency of...

Problems solved by technology

[0002] In agricultural production, the traditional furrowing and ridging method is mainly that the operator uses tools such as shovels to manually dig the furrows and riddles. This method of furrowing and ridging is labor-intensive and inefficient, especially on saline-alkali land. During ridge operation, due to the destruction of the soil structure in saline-alkali land, the compaction phenomenon is more serious, the ground surface is hard, and it is difficult to manually ridge and ridge, and the ridge is uneven, which cannot meet the requirements.
