Abstract

The utility model relates to a shovel type deep loosening machine comprising a frame, a shovel type deep loosening shovel, a dept limiting land wheel, and a land roller. The shovel type deep loosening shovel comprises a plane trapezoid shovel head and a shovel handle. The trapezoid shovel head of the shovel type deep loosening shovel is inserted into the soil, and therefore the soil is lifted and loosened; the depth limiting land wheel is used to limit the work depth. The land roller is used to compact the loose soil, crush the soil blocks, and press down the standing straws properly.

Description

The shovel subsoiler

Affiliated technical field

The utility model relates to a kind of agricultural machinery, and a kind of new-type subsoiler particularly can significantly reduce dark loose operation resistance and the subsoiler that improves dark loose operation quality.

Background technology

Subsoiler is to be widely used in that arable soil is carried out deep layer (30cm following) is loose, to improve precipitation infiltration speed, increases the Work machine of soil water storage amount.At present domesticly organize by the Ministry of Agriculture; " protective farming technique " in the enforcement of northern area large tracts of land; exactly based on dark loose operation; without ploughing; cover ground with discarded agricultural crop straw, stubble; with no-tillage seeding machine sowing, reach and surge, getting fat, reduce cost, increase farmers' income, realize an advanced technology of agricultural sustainable development.The subsoiler in China present production and supply market has " omnibearing-deep ploughing machine ", " dental formulas subsoiler " two kinds of basic models.Operation stalk occurs to the omnibearing-deep ploughing machine easily under the situation on stalk, stubble covering ground, stubble blocks up, and the dark loose scope in top is big, and the dark loose scope in bottom is little, can not eliminate effectively and hinder the tillage pan that oozes under the moisture.The dental formulas subsoiler can be worked under the situation that stalk, stubble cover, but the dark loose scope in same bottom is little, the tillage pan that oozes under the moisture of can not effectively eliminating the effects of the act.And above-mentioned two kinds of type working resistances are all bigger; the dilatory machinery of China rural area present a fairly large number of car pusher-55 type (40 kilowatts of power) traction; depth of implements can only reach below the 30cm; operation quality does not reach the elimination tillage pan; improve the best requirement of soil poultry outlet capacity, the implementation result of influence " conservation tillage project ".

Summary of the invention

In order to solve problem anxious to be solved in the above-mentioned production, the utility model provides a kind of novel shovel subsoiler.What this subsoiler was different with existing subsoiler is that dark loose workpiece is a kind of shovel type structure, can reduce working resistance significantly, enlarges the dark loose scope of bottom simultaneously, improves operation quality.

The technical scheme in the invention for solving the technical problem is: 5 novel shovel deep soil loosing shovels, 2 dark land wheels of limit, one group little arc press wheel packer parts are installed on frame.This novel shovel deep soil loosing shovel is made up of spade and shovel head.For alleviating working resistance, spade is connected to positive circular arc transition with the shovel head, and the shovel head is the planar trapezoidal structure, and the posterior transversal size is bigger, can increase horizontal loose range.The shovel head forms the wedge structure with the angle (equaling penetrating angle) of horizontal direction.Shovel head has the component that upwards lifts to soil all the time during work, compares with the workpiece of other forms of subsoiler, and to soil forward and less to the component of both sides pushing, the component that upwards lifts soil is bigger.Reach purpose with the loose topsoil soils of smaller working resistance.Limit dark land wheel to control the dark loose degree of depth.The soil block that press wheel is crushed and produced in the dark loose process, the soil appropriate compacting with fluffy makes soil crack up, prevents moisture loss, and overwhelms upright stalk, makes its close proximity to ground, more helps soil moisture conservation.

The beneficial effects of the utility model are:

(1), working resistance significantly alleviates, through model machine production practice examining, the tractor of label power about 40 kilowatts, in the area of height above sea level 1450m, dark loose depth of implements can reach 35cm-40cm.(2), big to the loose range of topsoil bottom, through model machine production practice examining, can realize that full working width (1.65m) is with interior whole loosening.(3), the suppression effect can crush soil block, soil that appropriate compacting is fluffy, overwhelm upright stalk, help soil moisture conservation.Above-mentioned beneficial effect is that the dynamic economics and the operation quality of dark loose operation reaches a new high.

Among the figure 1, shovel deep soil loosing shovel spade, 2, frame, 3, limit dark land wheel, 4, press wheel, 5, shovel deep soil loosing shovel shovel head.

Embodiment

In tractor-drawn subsoiler when work,, under the moment loading that buries, deep soil loosing shovel (1) buries rapidly, meet the requirements of working depth after, gauge wheel (3) supports ground, controlling depth, and with the ground profiling.The degree of depth that makes deep soil loosing shovel (1) is in desired scope (35-40cm) all the time, and it is steady to reach depth of implements one living load of making peace.The first tillage pan of incision topsoil soils bottom of the shovel head (5) of deep soil loosing shovel in the work along with advancing of machine, upwards under the effect of component, lifts soil at shovel head (5), makes soil loosening.And 5 deep soil loosing shovels make fabric width 1.65m all loose with interior topsoil soils each other to the effect that involves of soil.Press wheel (4) rolls on the ground after loosening, and under the effect of self gravitation, soil that appropriate compacting is loose and crushing soil block overwhelm upright stalk and make the soil crack of generation in deep soil loosing shovel (1) motion up.

Claims

1, a kind of shovel subsoiler, by frame, shovel deep soil loosing shovel, limit dark land wheel, packer to be linked in sequence to form, it is characterized in that: deep soil loosing shovel is a kind of shovel type structure.

2, according to the described shovel subsoiler of claim 1, it is characterized in that: the shovel deep soil loosing shovel is made up of spade and shovel head, and the shovel head is a planar trapezoidal, and the shovel head is connected to positive circular arc transition with spade.
