In this embodiment, referring to fig. 2 with 6, the width of the bending part of the rotary machetes 1b and applicator boot 2 Similar width.
In this embodiment, referring to fig. 2, the shaft of the rotary cultivator 1 is equipped with an opposite side block clearing straight knife 1c, and an opposite side is clear Stifled straight knife 1c is separated by 180 °.
In this embodiment, referring to fig. 2,5,6, the gap of rotary machetes 1b and applicator boot 2 is 5-10mm;Side block clearing Straight knife 1c and 2 side clearance 3-8mm of applicator boot.
In this embodiment, referring to fig. 2,3,7, the front end of 2 lower part of applicator boot has prone circular arc Structure, the rotary machetes 1b turn to the arc structure apart from it is nearest when, both rotary machetes 1b and arc structure are most The respective tangent line of near point is parallel to each other;Side block clearing straight knife 1c is provided with single-side cutting edge, and cutting edge side is close to 2 side of applicator boot.
In this embodiment, referring to Fig. 8-9, the bottom surface of the long band 705 of rubber is plane, and the long band 5 of rubber is length Cube structure;The support construction includes a support arm 701, and support arm 701 has two cantilever arms up and down, divides on each cantilever arm Not Zhuan You bearing, upright bar 704 is mounted on cantilever arm by bearing, is connected with sprocket wheel between two cantilever arms in upright bar 704 703, seeder is connect by chain with sprocket wheel 703, and upright bar 704 is driven to rotate;Bottom of upright rod and disk 707 weld, outside disk Edge has 4 holes, is connect by 4 long bands 705 of connection ring 708 and 4 rubber.
In this embodiment, referring to Fig. 7, the sprocket wheel 703 is located at two cantilever arm middles position.
Working principle is described in detail below: with continued reference to Fig. 1, forefront has rotary cultivator 1, will in operation on uncultivated land Soil rotary tillage arranges.Rotary cultivator 1 is followed by applicator boot 2, and feature is deep fertilizer spraying, applies fertilizer than general seeder deeper, And it in the direction of machine travel, is located along the same line with the seed opener at rear, the depth of applicator boot 2 is opened than sowing 5-8 centimetres of the ditching depth depth of ditch device 6, that is to say, that after seeder is passed by, 5-8 of the fertilizer line position immediately below kind of sub-line Centimetre depth.At the rear of applicator boot 2, there is an axis, the middle section of axis is equipped with rotary-cutting type plough 3, engaged therewith It is gutter ditching plow 5, effect is that the soil for unscrewing rotary-cutting type plough clears out, makes channel forming, thus in sowing width A gutter is opened in wide middle position;The both sides of plough are equipped with auger conveyor 4 on axis, and effect is to open centre The soil that ditch device is left shakeouts toward two sides conveying, while playing the role of that soil is made to become consolidation, keeps seeder bed smooth tight It is real, it is conducive to germination and grows.It is seed opener 6 backward again, seed opener 6 is a Duan Yuanguan, and rear portion bending is opened tiltedly Mouthful, a deep 2-4 centimetres of ditch is marked in the lower part of angle in soil, and seed is after feed mechanism for seed discharge through plough internal cavities Into in the ditch held successfully.In the flexible casing mechanism 7 in 6 rear of seed opener, seed furrow two sides soil is squeezed into ditch and is covered Lid seed, and appropriate compacting soil.
Use background about flexible casing mechanism 7: the glutinous weight of southern area soil, rotary tillage are not easy fine crushing, and consistency of soil Greatly, it is easily adhered on press wheel, causes suppression of soil effect poor.
When flexible casing mechanism 7 works, the disk in upright bar 704 quickly turns under seeder power drive close to ground Dynamic, long band also rotates under disk drive, and under 706 metal blocks and the long centrifugal action of band 705 of rubber itself, the long band of rubber is got rid of It opens, soil block and stalk are broken under the action of long band 705 and break up.The earthing compacting device phase of the long band of flexible rubber and metal Than having the advantage that: 1, flexible rubber length can be deformed constantly with itself, and the soil adhered to it can Automatic-falling.2, long band exists It is thrown away outward under centrifugal action, if having adhered to soil and stalk, soil and stalk are also thrown out of quickly.Length takes just in this way It is not easy clay.3, such mechanism can avoid being not easy large clod fine crushing automatically, only smash out a small amount of hack, and hack will plant ditch Interior seed earthing, stalk, which is also broken up, is covered on soil surface, is conducive to germination and growth.
It is the preferred embodiment of the utility model above, those of ordinary skill in the art can also carry out respectively on this basis Kind of transformation improves, and under the premise of not departing from the utility model total design, these transformation or improves this reality all should belong to Within the scope of novel be claimed.
