Abstract

A novel intertillage weeding machine comprises a frame, traveling wheels, a spherical disc and a herringbone shovel. When in cultivation, the spherical disc can not only cut off the soil layer and cut off residual films of stubble roots in the soil, but also can turn up and break up ridges in intertillage with the soil layer, and the herringbone shovel at the back can immediately deeply loosen and level the ridges.

Description

A kind of extirpator

The utility model relates to agricultural machinery, a kind of extirpator that has particularly improved.

The middle plowing device of existing cultivating tillage equipment is generally rotary hoe and shovel.Before seedling or seedling stage intertillage is loosened the soil, during weeding, because the vertical backplate area of left and right sides single-blade shovel is little, it is very poor to keep off native seedling-protection effect, the part that double-vane shovel or scalpriform shovel will be ploughed pine is loosened the soil and soil block is translated into Miao Hangshang, weigh wounded and kill the seedlings of cereal crops, the horizontal edge of shovel tilling depth of single-blade shovel only has 4-6 centimetre, when level is cut off weeds, not dead grass roots will regrow, in addition, when disconnected stubble of crops undesirable root and residual plastic sheeting for farm use earth working how, shovel is ploughed the table that is unearthed with stubble root, residual film, causes and drags seedling, hinders seedling or workpiece and stop up, intertill of poor quality, inefficiency.

The purpose of this utility model is to provide a kind of hack ability strong for fear of the weak point of above-mentioned technology, do not gather around soil and bury seedling, the weeding ratio height, the stubble root that occurs in the time of avoiding farming again, residual membrane stack collection are hindered the extirpator of a kind of high efficiency of seedling phenomenon.

The utility model is achieved in that this extirpator by frame, travelling wheel, sphere garden dish, and the herringbone shovel is formed.Frame front is equipped with travelling wheel, fixedly mounting vertical shaft seat respectively on the crossbeam of the left and right sides, middle part of frame, the vertical shaft upper end is installed in the vertical shaft seat, the vertical shaft lower end is provided with the transverse axis cover, sphere garden dish is bound up by bearing and transverse axis, the other end of transverse axis is installed in the transverse axis cover of vertical shaft lower end, and two sphere garden dishes are installed in the frame both sides respectively, are installed with the herringbone shovel at the rear portion of frame.

When the intertill and clean tillage machine operation, rim, sphere garden seedling-protection regional boundary cuts soil layer, and blocks the herringbone shovel simultaneously and dig loosening the soil and soil block at the band that loosens the soil.Because the drift angle of sphere garden dish is adjustable, except that cutting native hack, and make intertillage band soil layer turn over broken ridging, weeds connect root and rout up the face of land, and the dark immediately loose level ridges of herringbone shovel of back seethes weeds once again, and most of grass roots is exposed at the soil table and dries up.In addition, during farming, sphere garden dish cuts off the residual film of stubble root in the soil, has avoided the accumulation of stubble root, residual film and the pressure seedling that causes, and the phenomenon and the workpiece of hindering seedling stop up the parking accident that causes.

This utility model is simple in structure, and is reasonable in design, easy to use, and not only the hack ability is strong, do not gather around soil and hinder seedling, and herbicidal effect is good, the heap of having avoided the residual film of stubble root tired and cause drag seedling, hinder the shortcoming that seedling and workpiece stop up, improved intertillage operation work efficiency.

Fig. 1 is the front view of extirpator, and Fig. 2 is the attached view of extirpator, and Fig. 3 is a sphere garden disc assembly front view, and Fig. 4 is the partial sectional view of sphere garden dish.

The utility model is described in further detail below in conjunction with accompanying drawing.In the front portion of frame 1 travelling wheel 2 is housed, on the crossbeam 6 of the left and right sides at the middle part of frame 1, fixedly mounting spindle drum 5 respectively, the upper end of vertical shaft 8 is installed in the vertical shaft seat 5, the lower end of vertical shaft 8 is provided with transverse axis cover 9, one client link of the bearing of sphere garden dish 3 by dress in the bearing block 10 and transverse axis 7 together, the other end of transverse axis 7 is installed in the transverse axis cover 9 of vertical shaft 8 lower ends, 3 both sides that are installed in frame 1 are respectively coiled in two sphere gardens.The mounting shift angle of two sphere garden dishes 3 and height can rotate and move up and down in vertical shaft seat 5 and regulate by vertical shaft 8, use bolted after the adjusting.Lateral separation between two sphere gardens dish 3 can laterally move adjusting by transverse axis 7 in the transverse axis cover 9 of vertical shaft 8 lower ends, use bolted after the adjusting.Be installed with herringbone shovel 4 at frame 1 rear portion.

When using this extirpator, at first according to line-spacing of crops and the lateral separation between the seedling-protection width adjustment two sphere gardens dish 3, according to soil property and the definite drift angle of regulating two sphere gardens dish 3 of the intertillage degree of depth, generally between 10-20 °, soil property is sticking heavy, and tilling depth is dark more, and then the drift angle is big more.When this extirpator was worked, sphere garden dish 3 cut soil layer along the seedling-protection regional boundary, and blocked herringbone shovel 4 simultaneously and dig loosening the soil and soil block at the band that loosens the soil, thereby had avoided burying seedling, pressed the phenomenon of seedling.For the tough soil that hardens, sphere garden dish 3 cuts native dash board crust, has improved the hack effect, and the bulk soil block of having avoided hardening is connected the soil zone seedling by herringbone shovel 4 and opens the situation of hindering seedling.Because two sphere gardens dish 3 has certain drift angle, when cutting soil layer, not only the residual bar of stubble root in the soil is cut off, and make intertillage band soil layer turn over broken ridging, weeds connect root and rout up the face of land, and the herringbone shovel 4 dark immediately loose level ridges at rear portion seethe weeds once again, most of grass roots is exposed at the soil table and dries up, and herbicidal effect is good.Because a stubble root residual bar has been cut off, thereby the interrupted trouble of shutdown of having avoided the obstruction of extirpator workpiece to cause makes intertillage work operations efficient improve 15-20%.

Claims (1)

1. extirpator, form by frame 1, travelling wheel 2, sphere garden dish 3 and herringbone shovel 4, travelling wheel 2 is equipped with in the front portion that it is characterized in that frame 1, fixedly mounting vertical shaft seat 5 respectively on the crossbeam 6 of the left and right sides, middle part of frame 1, the upper end of vertical shaft 8 is installed in the vertical shaft seat 5, the lower end of vertical shaft 8 is provided with transverse axis cover 9, sphere garden dish 3 is bound up by bearing and transverse axis 7, the other end of transverse axis 7 is installed in the transverse axis cover 9 of vertical shaft lower end, two sphere garden dishes 3 are installed in the both sides of frame 1 respectively, are installed with herringbone shovel 4 at the rear portion of frame 1.
