Seedling-protecting, soil-cutting, rotary-tilling and pressing combined device

Abstract

The invention provides a combined soil preparation machine with functions of seedling protection, soil cutting, ditching, rotary tillage, soil crushing, pressing and soil moisture conservation for crops such as vegetables and corns. The combined soil preparation machine comprises three parts: firstly, a breast board type seedling protection device is designed, and crop stems and leaves are pushedto the peripheries of a disc cutter and a rotary cultivator during operation, so that the stems and leaves are prevented from being cut; secondly, a disc type soil cutting device is designed and installed on a machine body of a common mini-tiller, the position of a cutter head is adjusted according to the row spacing of the crops during operation, a soil cutting disc is tightly attached to the roots of the crops to cut soil according to the growth characteristics of roots of the crops, and small ponding ditches are formed; and thirdly, a rear output shaft of the common mini-tiller is connectedwith the rotary cultivator, the rotary cultivator is used for unscrewing the soil and preliminarily crushing the soil, the rotary tillage depth is adjusted by utilizing the height of a pressing roller and the pre-tightening force of a floating spring, and the pressing roller not only can limit the rotary tillage depth of a subsoiler, but also can further crush soil blocks to achieve the effects of limiting the depth, crushing the soil and preserving soil moisture.

Description

technical field [0001] The invention relates to intertillage equipment for vegetables, corn and other crops, in particular to an agricultural machine for protecting seedlings, cutting soil, crushing soil and suppressing it. Background technique [0002] Intertillage and weeding of crops and squatting seedlings to promote growth are effective means to promote crop yield, prevent lodging, and save water. At present, the micro-tillers produced in my country drive rotary tillers to loosen soil and squat seedlings. They have no function of cutting soil and are easy to damage crop roots. Cause crop malnutrition, water can not be well absorbed, affect crop yield. The invention can protect the seedlings and cut the soil in advance, integrate the functions of seedling protection, soil cutting, crushing soil, suppression and moisture preservation, and complete the processes of cutting soil, crushing soil and suppression at one time, so as to ensure that the stems, leaves and roots of t...
