Description
Technical field
The invention belongs to agricultural machinery technological field, in particular to a kind of patch ground seeding and fertilizing composite working rig.
Background technique
Traditional crop seeding fertilising is carried out generally by artificial, with the development of technology, currently, crop seeding
It applies fertilizer and realizes mechanical work extensively, first ditches before sowing, sowed at trench digging, finish kind and refertilize.In the prior art, open
One patent name is the Chinese invention patent of " wheat cultivation fertilizer applicator ", day for announcing 2018.04.20, which includes
Frame body, frame body are equipped with seeder combined with fertilising apparatus, and seeder combined with fertilising apparatus includes the fertilizer box and plants case being arranged in above frame body, under fertilizer box
Side is provided with fertilizer guiding tube, and grain conductor is provided with below plants case, and grain conductor insertion is sowed in conduit, and fertilizer guiding tube is inserted into fertilizing tube
In, in this technology, the seed in plants case successively pass through grain conductor and sowing conduit falls into the ditch held successfully, the fertilizer in fertilizer box according to
Secondary to fall into the ditch held successfully by fertilizer guiding tube and fertilizing tube, the length of grain conductor and sowing pipe is very long, and fertilizer guiding tube and fertilising are led
The length of pipe is also very long, and under the biggish external environment of wind-force, wind can blow fertilizer guiding tube, fertilizing tube, grain conductor and sowing pipe,
Fertilizer guiding tube is easily separated from fertilizing tube and fertilizer is directly dropped out out of fertilizer guiding tube, and grain conductor is easily separated from sowing conduit and to plant
Son is directly dropped out out of grain conductor, at this point, the direction that seed and fertilizer fall is unknown, seed and fertilizer will not may all fall on ditch
Interior, fertilizer is also possible to not fall on seed, can not provide sufficient nutrient to seed；Even if fertilizer guiding tube and grain conductor can be with
It is steadily respectively inserted in fertilizing tube and sowing conduit, fertilizer guiding tube, fertilizing tube, grain conductor and sowing pipe are easy in wind-force
Under the action of rock, for shallow ridges, seed, fertilizer can not accurately be fallen into ditch, not can guarantee seeding and fertilizing
Depth.
Summary of the invention
It is an object of the present invention to overcome shortcoming in the prior art, a kind of patch ground compound work of seeding and fertilizing is provided
Industry machine solves the technical problem that not can guarantee seeding and fertilizing depth in the prior art, and seed and fertilizer can be accurate in the present invention
It falls into the ditch held successfully, it is ensured that seeding and fertilizing depth, operating efficiency are high.
The object of the present invention is achieved like this: a kind of patch ground seeding and fertilizing composite working rig, including rack, the rack
On be fixed with seeder combined with fertilising apparatus, front support roller, seeding and fertilizing have been rotatably coupled in the rack in front of seeder combined with fertilising apparatus
Rear support roller is rotatably coupled in the rack at device rear, in the rack between the front support roller and seeder combined with fertilising apparatus
It has been rotatably coupled trench digging axis, has been placed with several seed manure trench diggings portion, seeder combined with fertilising apparatus and rear support roller on the trench digging axis
Between rack on be rotatably coupled earthing axis, be placed with several earthing knives on the earthing axis, the earthing knife setting
On the direction of seed manure trench digging portion outwardly, the rack rear portion is connected with liftable support device and ditching device, described to open
Ditch device is on seed manure trench digging portion direction outwardly.
The front of rack and rotary cultivator or the liftable connection of tractor in the present invention, the power output of tractor is through passing
Dynamic structure drives the rotation of trench digging axis, earthing axis respectively, and when work, tractor or rotary cultivator first fall the working rig, trench digging
Device is fallen, and when being contacted with ground, this working rig no longer declines current support roller, and front support roller carries out the field after rotary tillage flat
Whole, seed manure trench digging portion carries out out kind of ditch to the field after smooth and opens fertile ditch, and seeder combined with fertilising apparatus is sprinkled into seed simultaneously in kind of ditch
Fertilizer, the rotation of earthing axis are applied into fertile ditch, earthing knife is thrown after smashing soil, makes to finish in the ditch cave covering of kind and Shi Wanfei
One layer of soil, rear support roller will finish kind and cover native ground and suppress, and ditching device ditches to the field after suppression,
In turning, support device is fallen to be risen working rig with ground face contact, ditching device, and ditching device with ground face contact, does not improve
Stationarity when working rig is turned, working rig turning terminate, and ditching device is fallen, and support device rises, and repeat the above work
Industry step, until seeding and fertilizing all terminates；Present invention realization patch ground seeding and fertilizing, front support roller and rear support roller are set
Setting keeps seeding and fertilizing more steady, provides more stable planting fertilising plane, falls into seed and fertilizer accurately in shallow ridges,
Bud ratio is high, and budding is neat；The smooth ditch of ploughing the first furrow as a guideline of seeding and fertilizing earthing is integrated in one by this working rig, and operating efficiency greatly improves,
Without secondary operation, operation quality is further increased；It can be applied in the work of agricultural tillage.
In order to further increase operation quality, seed manure trench digging portion includes opening fertile ditch portion, and the two sides for opening fertile ditch portion are to open
Kind ditch portion, opening fertile ditch portion and opening kind of a ditch portion can be integrated, and the earthing knife is opening the side of kind of ditch portion outwardly；This design, which is realized, to be opened
Kind ditch and the synchronous progress for opening fertile ditch, disposable to complete trench digging movement of kind of the ditch with fertile ditch, each ditch cave is obvious, guarantees operation matter
Amount.
As a further improvement of the present invention, the seeder combined with fertilising apparatus includes Seeding box and fertilizing box, and Seeding box is being applied
The front side of fertilizer box, the bottom of Seeding box are placed with several sowing openings, and the bottom of the fertilizing box is placed with several fertilization mouthes, each
The two sides of fertilization mouth are flushed with the two sides for each opening fertile ditch portion.
In order to realize the controllability of sowing and fertilising, the bottom of the Seeding box is placed with several electric seed sowing mechanisms, described
The seed inlet of electric seed sowing mechanism and the position of sowing opening are corresponding, and the downside of electric seed sowing mechanism is equipped with partition, the left and right sides of partition
Respectively planting mouth, in the lateral direction, the planting mouth are corresponding with the position for opening kind of ditch portion, two sides of each planting mouth and every
A two sides for opening kind of ditch portion flush；In this design, by the setting of independent electric seed sowing mechanism, the application rate in each ditch cave is obtained
To effective control；The bottom side of the fertilizing box is placed with several several groups jettron components corresponding with fertilization mouth, the gas
Dynamic switch block include fertilization mouth two sides are set there is accommodating chamber and the identical bearing seat one of structure and bearing seat two, backgauge
