Description

A kind of subsoiler

Technical field

The utility model belongs to agricultural mechanical field, relates to a kind of subsoiler.

Background technology

Subsoiler is to be widely used in that arable soil is carried out deep layer is loose, to improve precipitation infiltration speed, increases the Work machine of soil water storage amount.The structure of the subsoiler of China's production at present mainly comprises frame, deep soil loosing shovel handle, spear, regulating wheel, upward suspension is sold, suspension is sold down, but there is following problem in the subsoiler of this structure, 1) in the middle of operation, foreign material stop up before being easy to be shoveled, and influence operation quality, increase operation resistance: 2) because the soil layer of the drying on ground and dark pine is thicker, occur the large clod phenomenon easily, cause face of land injustice, influence subsequent job, simultaneously, easily cause the soil moisture loss.

Summary of the invention

At the shortcomings and deficiencies that exist in the above-mentioned prior art, the purpose of this utility model is to provide a kind of subsoiler simple in structure, easy to operate, easy to utilize, this subsoiler has effectively solved the weeds that occur in the operation and has stopped up and the large clod phenomenon, reduce the water evaporates loss, improved operation quality and production efficiency.

The technical scheme that realizes above-mentioned utility model purpose is a kind of subsoiler, it comprises that there is the frame of connecting plate a positive front end top, one be opposite to the frame front end on, lower suspension arm, a pair of by the gauge wheel axle, the gauge wheel bracing frame, the gauge wheel bracing frame connects the gauge wheel that screw rod is connected the frame both sides, a deep soil loosing shovel handle that has the deep soil loosing shovel point that is connected with the frame postbrachium by deep soil loosing shovel fixed head and deep soil loosing shovel fastening screw has one by colter connecting rod fastening screw in the front upper place of deep soil loosing shovel point, the colter connecting rod, the disk plow cutter shaft, the rolling coulter that the rolling coulter support is connected with connecting plate; Described rolling coulter and deep soil loosing shovel handle center are on a line; Described deep soil loosing shovel point is a flechette-type, and the deep soil loosing shovel handle is a bending, and deep soil loosing shovel handle radius of curvature is taked gradual change design, with the raising effect of loosening the soil, reduces working resistance.

Between frame postbrachium and gauge wheel bracing frame, also be connected with and regulate the adjusting rod of the gauge wheel degree of depth by adjusting nut and adjusting rod fastening screw.

Subsoiler operation principle of the present utility model:

During operation; to place frame the place ahead to use; lower suspension arm is in being connected with the corresponding linking arm of tractor; tractor moves forward the traction subsoiler and moves forward; make the rolling coulter and the ground that are positioned at deep soil loosing shovel point and deep soil loosing shovel handle front upper place produce frictional rotation; rolling coulter rotates the weeds and the top layer, ground in the place ahead is cut open; make the deep soil loosing shovel handle of back when work, can not be subjected to the influence of the place ahead weeds; simultaneously; because locating the rotary disk colter in the place ahead cuts the top layer, ground open; the back when dark pine, reduced greatly by the resistance of ground surface dry ground layer; the scope of soil activity is diminished, the large clod phenomenon can not occur, also play the effect of protection moisture loss.

The deep soil loosing shovel handle of subsoiler of the present utility model is a bending, and radius of curvature changes mild, and the deep soil loosing shovel point is positioned at the back lower place of rolling coulter, and the deep soil loosing shovel handle has cutting edge in direction of advance, when effect is loosened the soil in assurance, reduces its working resistance.

The anthropogenic soil degree of depth of subsoiler of the present utility model changes two adjusting rod length by adjusting nut, realizes the stepless control to gauge wheel.

The height of the rolling coulter of the utility model subsoiler is realized by regulating colter connecting rod fastening screw, colter connecting rod and connecting plate position.

Subsoiler of the present utility model has effectively solved and has been stopped up by weeds in the operation and the large clod problem occurs, and simultaneously, also the soil moisture conservation effect of loosening the soil is really played in effectively protection soil moisture loss.
