Abstract

The utility model relates to a semi-suspension loosener which belongs to the technical field of agricultural tillage machinery. The utility model aims to provide a minimum tillage implement which loosens the land as the plowing and combines the loosening with the raking. The semi-suspension loosener is characterized in that a disk rake set (1), a deep loosening machine frame and a soil loosening component (2) are oppositely arranged in the front row, a disk rake set (3) is oppositely arranged in the rear row, the disk rake set (1), the deep loosening machine frame, the soil loosening component (2) and the disk rake set (3) are orderly arranged on a machine frame (4), and the semi-suspension loosener adopts the semi-suspension mode to be hung and connected with a tractor. The semi-suspension loosener has the advantages of compact structure, flexible operation and transport and low cost. The utility model can be adapted to the minimum tillage rotation agriculture requirement, loosens the land as the plowing and combines the loosening with the raking under the conditions of the heavy soil and the dense stubble crops. The semi-suspension loosener is particularly suitable to being matched with a crawler tractor to use.

Description

Semi-pendulous loosener

The utility model belongs to the agricultural tillage mechanical field.

Since the eighties, the conventional tillage method of year after year ploughing is just progressively replaced by new cropping system.Wherein, turn over, pine, the less-tillage system that combines of rake combine with the Different Crop rotation system, formed one and overlapped the effective crop rotation agronomy of minimal tilling, just push open in vast state farm of northern China and rural area.But the facility of realizing this class farming agronomy at present are still based on single entry operation mouldboard plow, subsoiler, disk harrow, and the multiple operation type is in lead-in stage.This class multiple operation type roughly has dark pine to combine with ploughing, and is combined in the combination plow of a machine by ploughshare and Rod tine for working subsoil; Dark pine combines with the top layer hack, is combined in the dark loose tiller combine of a machine by Rod tine for working subsoil and astrolabe; Loosening the soil combines with rotary tillage and ridging, is combined in " pine, revolve, rise " facility of a machine by break shovel, rotary ploughing part and ridging shovel; Dark pine combines with rake stubble hack, is combined in dark pine rake stubble machine of a machine or the like by Rod tine for working subsoil and disk harrow group.Wherein, dark pine rake stubble type is particularly suitable for the supporting crawler tractor that has a large capacity and a wide range and uses because it is intrinsic, demonstrates good prospects for application.But, only there is suspension type a kind of so far, promptly utility model patent " moves readjustment angle suspension type loosener " (patent No. 92224631.9) automatically.

The purpose of this utility model provides a kind of semimounted loosener, minimal tills the crop rotation agriculture requirement with what adapt under heavy soil and close stubble crop condition substituting-loose-to-ploughing, the combination of pine rake.

The utility model semimounted loosener is formed, and is installed on the frame successively by prostatitis symmetrical disc harrow group, subsoiler frame and the parts that loosen the soil, rank rear symmetrical disc harrow group.Rake group drift angle, the break shovel degree of depth and position are all adjustable, and half suspension realizes by the sharp tail wheel of hanger bracket.Tail wheel drives the parallel-crank mechanism interlock and lifting by a connecting rod that is hinged with last hitch point, and can swing within the specific limits.

The utility model semimounted loosener has a good application prospect.Compare with the pickup harrow machine, owing to adopt half hang, machine is heavy can be increased the weight of, and adapts to substituting-loose-to-ploughing under heavy soil and close stubble crop condition, the combination of pine rake minimal till the crop rotation agriculture requirement; Because this type is determined master-plan by rake, pine, rake operation, present, rank rear rake is organized opposed layout, so compact conformation, and operation effectiveness is good.This is because the downward component that produces when loosening the soil the parts operation is limited by prostatitis rake group, not only can save the dark measure of limit, and helps the prostatitis disk effect of burying; The relative position of deep soil loosing shovel and disk harrow group can rationally be adjusted, so the low bank of earth between fields in the middle of the unlikely generation has guaranteed grading.Compare with towed, because the connecting rod that employing and last hitch point are hinged drives parallel-crank mechanism interlock lifting tail wheel, so can save one tunnel hydraulic system, cost is low, maneuverability, and avoided the difficult difficult point of arranging of towed loosener travelling wheel system.

Fig. 1 is the elevational schematic view of semimounted loosener;

Fig. 2 is the schematic top plan view of semimounted loosener;

Below in conjunction with accompanying drawing most preferred embodiment is illustrated:

The semimounted loosener is made up of prostatitis symmetrical disc harrow group (1), subsoiler frame and the parts that loosen the soil (2), rank rear symmetrical disc harrow group (3), is installed in turn on the frame (4), and rake group drift angle and break shovel and depth of implements and position all can be adjusted.Half suspension is to realize by hanger bracket and tail wheel.Lower link is hinged on hanger bracket and the tractor, and tail wheel drives parallel-crank mechanism (6) by a connecting rod that is hinged mutually with last hitch point (5) and realizes the interlock lifting, and can swing within the specific limits.

Claims

1, the utility model semimounted loosener is made up of subsoiling component and disc set, it is characterized in that prostatitis symmetrical disc harrow group (1), subsoiler frame and the parts that loosen the soil (2), rank rear symmetrical disc harrow group (3), be installed in turn on the frame (4), tail wheel by one with facility on the connecting rod (5) that is hinged of hitch point drive parallel-crank mechanism (6) and realize the interlock lifting and can swing within the specific limits.
