Description
Technical field
The utility model relates to field furrower tool technical field in the agricultural machinery, be specifically related to the towed trench digging device of a kind of associating seed-sowing machine, emphasis is to solve the problem that resistance is big, tractor dynamic power can not get effective utilization of ditching when the associating seed-sowing machine is opened railway carriage or compartment ditch operation, and this system also can be used for the ditching operation of other farm working machinery.
Background technology
China's southern area rainwater is more, generally need leave every several row in the time of sowing to be used for irrigating when a railway carriage or compartment ditch is beneficial to draining or meets drought.Machinery leaves the railway carriage or compartment trench culture and already mainly contains dual mode: a kind of is that trench digging is sowed again earlier, this kind method is successively finished out railway carriage or compartment ditch and seeding operation with different machines, both time-consuming, take a lot of work, cause the repeatedly compacting of machine again, and sowing the time may destroy the ditch type of holding successfully originally to ground; Another kind is to use the integration of operation sower to finish out the railway carriage or compartment ditch in seeding operation.The mode that present domestic integration of operation sower is opened the railway carriage or compartment ditch mainly also has two kinds: a kind of is with rotary blade soil to be smashed again to go out complete ditch type clearly with earth-cleaning shovel.The method trench digging ditch type is more neat, but needs tractor motive power output shaft that power is provided, and adopts gear-box to give the rotary ploughing cutter shaft transferring power, generally need add kind of a bed band rotary tillage, causes complete machine structure complexity, weight heavier, requires to be equipped with powerful tractor.Another kind is to rely on tractor drawbar pull, and with the twin wrest trench digging, the complete machine structure of employing the method is simple, weight is lighter, but trench digging ditch type is neat inadequately, and the trench digging resistance is big, power consumption is high.
Summary of the invention
The purpose of this utility model is to overcome the technological deficiency of existing ditching machine, tractor dynamic power can not obtain reasonable use and problems such as the trench digging resistance is big, the difficult assurance of ditch type when opening railway carriage or compartment ditch operation at combined drill, and a kind of towed trench digging device of being made up of plough after plough and the clear native shaping before the breaking trench digging is provided.
The utility model is realized by following technical proposal:
The matching used towed trench digging of a kind of associating seed-sowing machine system, plough (13) before the place ahead of sower side plate (14) is symmetrically installed with two, plough (12) after the rear of sower side plate (14) is symmetrically installed with two; Plough (13) is the single face mouldboard plow before described, it comprises the preceding plough plow standard (1) that is welded as a whole, preceding plough plough face (2), preceding landside (3) and preceding slade (4), landside (3) is in alignment with direction of advance before described, preceding plough plough face (2) deflection face inboard, railway carriage or compartment; Described back plough (12) comprises back plough plow standard (5), back plough plough face (6), back plough earth separation plate (8), back landside (7) and the back slade (9) that is welded as a whole, and the working curved surface and the direction of advance of described back plough (12) are 20~30 ° of angles; Plough (13) and back plough (12) are connected on the holder (11) by bolt respectively before described; Described holder (11) is welded on the sower side plate (14); Be reserved with 3 installing holes on preceding plough plow standard (1) and back plough plow standard (5), its setting height(from bottom) is adjustable (the supporting setting height(from bottom) that can adjust plough in the hole of installing hole and holder).
In the utility model, the warping surface of plow bottom of described preceding plough unit line angle is 40 °~45 °, and the ratio of lead curve height h and aperture L is 1.7~1.8, and ploughshare sword earth lifting angle is 25 °~30 °, and two-end-point tangent line angle is 110 °~120 °.
During work, under the tractive force effect of tractor, preceding plough breaking, play soil, hack, dig, form smooth bottom of trench and certain furrow width; The back plough is cleared up the surface dust of bottom of trench, and surface dust is dug throwing to the face of railway carriage or compartment, and shaping operation is played in extruding to furrow bank simultaneously.
The plough body combination round trip of both sides is left a complete trapezoid-shaped trench.
The beneficial effects of the utility model are:
1, the utility model is made up of plough before two groups and back plough, preceding plough breaking trench digging, and the clear native shaping of back plough, the ditch type of ditching is neat, respond well;
2, plough is the single face mouldboard plow before the utility model, buries easily, and the trench digging resistance is little;
3, the utility model relies on the tractive force trench digging, has alleviated complete machine weight with respect to rotary tillage ditching, has rationally utilized the power of tractor, effectively reduces power consumption.
