Description
Technical field
The utility model relates to a kind of trench digging, fertilization all-in-one machine.
Background technology
In existing orchard planting or field planting operation process, using mechanization production is to improve efficiency and ensure the effective measures of product yield.Phase before planting, need to use machine to ditch and sow seeds, phase or the middle and later periods before planting, need to carry out fertilizer apparatus and apply fertilizer for kind of a plant, thus, above-mentioned trench digging to be realized and fertilising needs plough and fertilizer apparatus two to overlap engineering goods.The running of plough is to output kind of ditch or fertile ditch on whole good field, and seed or fertilizer is imported in ditch；The running of fertilizer apparatus is to output fertile ditch between rural area, is buried by fertilizer by soil in fertilizer imports ditch simultaneously again.
Existing plough is divided into portable and roller two class, and portable plough is that ditching knife front end spine enters soil, realizes trench digging by the dragging of engine, and its ability of burying is strong, and shortcoming is that ditching depth is limited and trench digging width is uncontrolled；The mechanism of action of roller plough is to install ditching knife in the rotating shaft that engine drives, under the turning effort of ditching knife, soil is dug, thus kind of ditch or fertile ditch occur, its trench digging speed is fast and ditching depth is big, but the part in the soil dug due to it and kick up can fall back in above-mentioned kind of ditch or fertile ditch, thus its trench digging uniformity is poor, trench digging width is undesirable, during fruit tree etc. needs the fertilising of big fertile amount, need carry out secondary boring ditch and then ensure the width of ditch, also the plough having uses the structure that the soil dug carries out sidepiece conveying, the soil making plane rise is transported to kind of ditch or the side of fertile ditch, its structure is complicated and there is the problem of earthing difficulty after fertilising or plantation.
The structure of existing fertilizer apparatus is, anterior at bracing frame installs colter, it is provided with at the rear portion of colter and is connected fertilising pipe with fertilizing box, it is also connected with being positioned at the trailing bar of fertilising pipe bottom rear on bracing frame, trailing bar is splayed, when engine drives bracing frame to run forward, ditched by colter, fertilising pipe falls fertilizer, trailing bar can scrape the soil on upper strata and be backfilled by fertilizer ditch, there is trench digging width in it and ditching depth is the least, the shortcoming of running resistance big (needing big power vehicle), and trailing bar can be scraped by surface dust elsewhere in fertile ditch and rigid burying is filled out, it is unfavorable for ensureing the soil moisture conservation of soil.Currently there are no a kind of machine both to have realized trench digging, ditching-fertilizing two kinds work can also be realized.
