seed is taken away, rotary blade is less than derotation rotary tillage compared to derotation cutter shaft group more sparse and embedded depth of arranging Knife, cutter shaft group rotation direction are buried for forward direction, and dextrorotation makes pushing of digging, and soil is avoided to splash forward, are subtracted on the influence of planting blockage It is small.Hydraulic lifting apparatus 11 is installed in dextrorotation little cutter shaft group 10, the upper and lower of cutter shaft bracket is realized by the stretching motion of hydraulic cylinder It swings, achievees the purpose that adjust thickness of earth-fill cover by job requirements.It is fixedly mounted and passes in the center of two cross bearers of rack 1 Dynamic case 12, the left output shaft of transmission case 12 drive derotation cutter shaft group 7 by cardan drive to left side side box, and transmission case 12 is right Output shaft is connected to the upper gear box 13 of selective ditching machine, and the right output shaft of upper gear box 13 of selective ditching machine passes through universal Section and chain conveyer drive dextrorotation little cutter shaft group 10 to work, and 13 vertical output shaft of upper gear box of selective ditching machine passes through universal joint The lower tooth roller box 14 for being connected to selective ditching machine provides trench digging power, and the lower tooth roller box 14 of selective ditching machine is opened selectively 15 right side of machine body of ditch machine, selective ditching machine 15 include main support 151, arc bracket 152, cutterhead 153, dissipate native deflector 154, Reshaping device 155.Main support 151 realizes mounting with rack 1 by being spirally connected, and cutterhead 153 is in complete machine center, dissipates soil deflector Main support 151 is welded in 154 two sides, and centre is welded on arc bracket 152, in conjunction with throw the earthwork to angle of digging to scattered native water conservancy diversion 154 metal plate configuration of plate optimizes, and drops into the groove held successfully to avoid trench digging from throwing native caudad dish out, elongates tail end cover Plate arc prevents back soil, throws soil to tail end and carries out inhibition gathering, collapses and arranges again into groove progress ditch type.Reshaping device 155 includes Ditch cleaning shovel 1551, side trim panel 1552, it is preceding stick up bottom plate 1553, flat underside 1554, function respectively correspond for ditch cleaning, side shaping and Bottom surface shaping, ditch cleaning shovel 1551 cambered surface radius slightly larger than trench digging cutter shaft radius, and that removes groove returns soil, and side trim panel 1552 has one Fixed toe-in and flare carries out outer support plastotype to groove, and bottom surface shaping plate is by preceding sticking up 1554 two parts of bottom plate 1553 and flat underside Composition, it is preceding to stick up bottom plate 1553 the front is high and the back is low, there is certain warpage angle, the soil that returns of groove is all pressed into bottom surface, and through flat Plate 1554 is compacted, and for the setting of 1554 depression depths of flat underside slightly larger than trench digging prescribed depth, the whole being compacted in groove returns soil, Guarantee groove it is clean and tidy, reshaping device 155 is screwed on arc bracket 152 by U-type groove, and can according to ditch requirement for height above and below It is adjustable.Wheat After Getting Rice rotary tillage stubble-cleaning ferti-seeding ditches the suitable caterpillar tractor of multiple operation principles of action selection power as traction On the one hand machine meets the farm work consumption of corresponding power, on the other hand mitigate wheeled tractor and sink in the operation of high humidity field And to the soil compression negative effect such as big, the high moisture work environment of matching combined working machine work.

Working principle:

The power input of composite working rig is transmitted to the power of transmission case by the power output shaft of dynamic power machine through universal joint Then input shaft exports respectively by transmission case power output shaft and drives derotation cutter shaft group and dextrorotation little cutter shaft group and selectivity Ditching machine.In the course of work, fertilizer apparatus feed mechanism for seed is driven by motor control respectively, and in a work direction, fertilizer is fallen through fertilizer road Onto untilled field, derotation cutter shaft rotary tillage is broken ground mixed soil and fertilizer, and seed is through plastic tube, planting pipe seeding, dextrorotation Cutter shaft, which gently revolves realization, gives seed earthing, and available hydraulic lifting device adjusts thickness of earth-fill cover, and selective ditching device is by hydraulic device Adjust working condition.

The clay attachment issue of planting pipe is solved from former and later two directions of planting pipe, before using adjustable damper block derotation The wet soil that cutter shaft group is got backward, behind using dextrorotation little cutter shaft group have certain firming function, guarantee that soil is dished out not high reduction Adhering to blocking to planting pipe influences, while replacing press wheel to solve suppression band soil, band kind, row in wet soil with dextrorotation little cutter shaft group The problems such as kind is uneven；

Ditching machine dissipates native deflector and reshaping device from structural modeling principle, and it is anti-to dissipate soil deflector elongation cover plate arc Soil is returned to open channels in rear, and ditch cleaning shovels cambered surface radius slightly larger than trench digging cutter shaft radius, removes groove and return soil, trim panel is prenex outer Incline, bottom is good after height before bottom surface solves the problems, such as that ditch type is not whole, groove profile is unclear.

This utility model adheres to adapt to wet field block rice after attribute carries out brand-new design to composite machine for wet soil Stubble wheat sows institutional operation condition, meets job requirements.

The utility model is disclosed with preferable implementation above, so it is all to take not to limit the utility model With replacement or equivalent transformation technical solution obtained, all fall in the protection scope of the utility model.
