Detachable flood and dry dual-purpose rotary embedded knife roller

Abstract

The invention relates a dismountable amphibious rototillingknife roller which resolves the problems of poor universality, high energy consuming, disable detachingand uneven stress of the knife. The rototillingknife comprises knife tools and a knife shaft. The knife tools comprise rotary blades, lateralscrew blades and curved blades groups. The knife shaft is provided with a plurality of knife disks and the knife shaft between the two adjacentknife disksis provided with a plurality of knife bases that the lateralscrew blades are installed inside,a plurality of the curved blades groups and rotary blades are alternately installed around the edge of the knife disk, and the lateralscrew blades are welded between the adjacent curved blades. On the two sides of the knife shaft, the knife tools are symmetrically arranged, rotating directions of the rotary blades are opposite and in the same rotary interval, the rotary blades and lateralscrew blades are arranged in reverse directions. The knife roller has the advantages of reasonable and compact structure, uniform stress, energy consumingconservation, high working efficiency, and goodreliability, dismounting easily, flexibility and convenience, good universality.

Description

technical field [0001] The invention relates to a cutter roll in agricultural equipment, in particular to a detachable rotary buried cutter roll for both water and dry use. Background technique [0002] Straw returning to the field can not only solve the problem of straw burning indiscriminately, but also is the most direct and economical method to reduce the amount of chemical fertilizers, improve soil quality, and increase soil fertility. The traditional rotary tiller roller has a simple structure and strong versatility, but the serious grass wrapping of the cutter roller causes unnecessary power consumption, and most of the straw cannot be buried into the plow layer, which affects the subsequent sowing and insertion work. The grass-burying knife roller has a good effect of throwing soil and turning the soil and covering it, but the resistance of the horizontal knife to the soil is large, so that the cutting edge wears seriously, the plowing depth is not enough, the power ...

AI Technical Summary

Problems solved by technology

The traditional rotary tiller roller has a simple structure and strong versatility, but the serious grass entanglement of the cutter roller causes unnecessary power consumption, and most of the straw cannot be buried in the plow layer, which affects the subsequent sowing and insertion work

The grass-burying knife roller has a good effect of throwing soil and turning the soil and covering it, but the resistance of the horizontal knife to the soil is large, so that the cutting edge wears seriously, the plowing depth is not enough, the power consumption increases sharply, and the efficiency is low

[0003] Invention patent 201410436141.8 "Combined straw returning rotary tiller roller" combines the traditional rotary tiller roller and grass-burying cutter roller in a reasonable combination, and one cutter roller realizes the functions of plowing and grass-burying, but the cutter roller The versatility is not strong, the spiral horizontal knife cannot be disassembled, the arrangement of the rotary tiller is complicated, and the force is uneven

For soils with high firmness (>1260kpa), the rare problem of horizontal knife entry into the soil is still unsolved
