Description

The loose plowing device of the shallow dark pine associating of a kind of soil

Technical field

The utility model belongs to agricultural mechanical field, is specifically related to the loose plowing device of the shallow dark pine associating of a kind of soil.

Background technology

Protective farming technique is applied the whole world; Produced the huge social economic benefit; But on clayey soil, carry out conservation tillage, can cause soil compactibility to increase, unit weight increases; Particularly increased topsoil unit weight, had a strong impact on that seeding quality and conservation tillage are conserved water and soil, the performance of cost-saving synergistic.Therefore, it is necessary that suitable pine is ploughed, even the U.S. etc. carry out conservation tillage country early, after having experienced more than 20 year no-tillage, is increasing table soil and dark loose operation again no-tillagely.But dark loose method is chesson not only, and the tillage pan of the operation that can also break traditions improves the soil organisms vigor, enlarges the root system living space.And table such as shallow pine soil is handled, and can reduce face of land unit weight, improves soil physical property, and enhance air permeability improves surface layer accumulated temperature, replaces broadcasting preceding weeding, and resistance is corresponding during sowing reduces, and makes the sower trafficability characteristic good, improves seeding quality.But under the conservation tillage condition, there are following problem in shallow pine of present soil and dark loose operation: (1) common rotary tillage is ploughed bigger to soil disturbance with rake; (2) homemade subsoiler is littler than the soil subsoiling degree of depth of external advanced type; (3) generally speaking, different units carry out shallow pine and dark loose operation to soil at twice, have increased the soil packing effect, although the subsoiler that can his-and-hers watches soil unscrews is also arranged, it does not meet the protective farming technique requirement to the big disturbance of soil.

Summary of the invention

To the problems and shortcomings that exist in the above-mentioned prior art; The purpose of the utility model is to provide the shallow dark pine associating of a kind of new soil loose plowing device, at first, and the motion of tractor motive power output shaft; After the gearbox speed change; Pass to slider-crank mechanism, utilize the fixing slide block of relative frame to drive shallow loose cutter and insert down and mention, reduce when loosening the soil disturbance as far as possible soil; Secondly, soil is to promote the effective force that unit advances to shallow loose cutter reaction force in the horizontal direction; And after soil top was loose, the resistance that loosens the soil of deep soil loosing shovel also can suitably reduce; Thereby reduce the tractive resistance of tractor; Therefore, under the certain prerequisite of tractor power, this associating pine is ploughed machine can increase the dark loose degree of depth to soil; The 3rd, the shallow dark pine combination operation of soil reduces unit and advances the ground number of times, reduces soil packing; In addition, for adapting to 2～3 years dark pines in conservation tillage ground once, annual shallow pine needs once, dark loose cutter can be dismantled as required, only as the shallow loose machine use of soil.

Realize that foregoing invention purpose technical scheme is the loose plowing device of the shallow dark pine associating of a kind of soil, form that described deep soil loosing shovel is installed in the rear end of frame by frame, deep soil loosing shovel; It is characterized in that; Be fixed with crankwheel on the described frame, the center of circle of said crankwheel is connected with the output shaft bearing of gearbox, is connected with an end of connecting rod on the described handle wheel; The described connecting rod other end is connected with upper end of slide block; The lower end of described slide block is provided with mounting groove, the shallow loose cutter that has been connected through the hinge in the described mounting groove, and described shallow loose cutter is fixed in the middle of the described mounting groove through back-moving spring.

The power input shaft of said gearbox is connected with the power take-off of tractor, and said deep soil loosing shovel is positioned at the back lower place of shallow loose cutter, and concrete depth location is relevant with the soil subsoiling degree of depth that needs; Shallow loose mechanism of said crank block and deep soil loosing shovel are connected with frame respectively, and deep soil loosing shovel is detachable.The relative tractor pace of the speed that pumps of said shallow loose cutter is higher, and cutter is under inserting and in the circulation of mentioning, and the displacement of along continuous straight runs is less, so that reduce the disturbance of shallow loose cutter to soil as far as possible; The reciprocating motion of said shallow loose cutter and unit direction of advance have an angle, so that cutter is inserted downwards when loosening the soil, soil produces a motive force forward to unit.

The operation principle of the loose plowing device of the shallow dark pine associating of the utility model soil: during unit work; Tractor at the uniform velocity advances, and the traction deep soil loosing shovel carries out dark loose operation to soil, simultaneously; Output shaft is through the unit gearbox; Drive the crankwheel rotation of slider-crank mechanism, promote slide block through connecting rod and do straight reciprocating motion, the shallow loose cutter that is positioned at the deep soil loosing shovel front upper place moves in the X-axis direction on the guide rail that frame is fixed relatively with slide block and loosens the soil.Cutter is from the beginning of burying; Break away from the face of land through maximum cutting-in to blade; Because tractor is at the uniform velocity advancing, cutter can receive soil obstruction in the horizontal direction, and at this moment spring is regulated automatically; Cutter will be around hinge deflection certain angle, thereby avoids cutter because the cross force of soil and cisco unity malfunction.

The utility model is in order to reduce the disturbance of shallow loose operation to soil; The relative tractor pace of the speed that pumps of cutter is higher; Cutter is being inserted down and in the circulation of mentioning, the displacement of along continuous straight runs is less, so that make cutter insert in position down and mention as far as possible; Under the certain prerequisite of tractor drawbar pull; The utility model has designed an angle in order to increase the degree of depth of unit chiselling earth between the reciprocating motion of the relative frame of shallow loose cutter and the unit direction of advance, so that cutter is inserted when loosening the soil downwards; Soil produces a motive force forward to unit; Thereby, under the certain condition of tractor-drawn resistance, increase pine soil depth.The utility model is for adapting to the annual shallow pine in conservation tillage ground once, and 2～3 years dark pines needs once, dark loose cutter can be dismantled as required, only uses as the shallow loose machine of soil.
