Helical oblique cross-row adjustable cultivator

Abstract

The invention discloses a spiral inclined cross-ridge adjustable ridging machine. The spiral inclined cross-ridge adjustable ridging machine comprises a machine frame. A hydraulic mechanism is arranged on the machine frame, and the lower portion of the machine frame is provided with a depth limiting mechanism, a soil loosening mechanism, a soil distributing mechanism and a spiral ridging mechanism from front to back in sequence. The spiral inclined cross-ridge adjustable ridging machine further comprises a ridging spacing adjusting mechanism arranged on the back of the machine frame. The ridging spacing can be adjusted according to the growing situation of crops in the intertillage ridging period and the soil situation through the ridging spacing mechanism, and the damage to the crops due to the over-wide or over-narrow ridging spacing is avoided. Ridge forms with different gradients can be formed through a ridge form adjusting mechanism according to the soil terrain situations, and the ridge form formed after ridging can be kept with a good original shape. The soil can be slantly milled and conveyed through the spiral ridging mechanism, the original mode that a ridging cutter blade pushes the loosened soil to the outer side of a packing auger, and the soil is thrown to the roots of the crops through the inertia is changed, the soil flow direction can be controlled, the mechanical damage to crops leaves can be reduced, and the soil ventilation performance is improved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a helical inclined straddle-row adjustable soil cultivator. Background technique [0002] During the growth period of crops in large fields, weeds often grow rapidly, and the ridges also drop a lot due to rain erosion, etc., and the soil will become compacted after the field has not been plowed for a long time. Therefore, it is necessary to loosen the topsoil and improve the soil compaction. Comfortable soil environment. Cultivation and soil cultivation is a weeding and soil cultivation operation achieved by mechanically improving the physical properties of the topsoil. Through intertillage, the relationship between crops, the environment and environmental factors during the field growth period can be coordinated, soil moisture can be adjusted, soil aeration can be enhanced, soil nutrient transformation can be accelerated, Raise the soil temperature while eradicating weeds in the field...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the existing defects of the above-mentioned soil cultivator, the technical problem to be solved by the present invention is that the soil cultivator in the prior art cannot adapt to the growth height of crops due to the fixed ridge distance and ridge shape, and it will inevitably be used in intertillage. The crops are damaged during the soil cultivation process. The existing soil cultivation methods will cause the loose soil to be thrown onto the crop leaves due to inertia, resulting in crushing of the crop leaves. The work efficiency is low, the function is relatively single, and the major disadvantages of mechanical damage to the crops
