Background technology
China is one of serious water shortage country in the world, and in recent years because water resource lacks, and the professional of agriculture has thought thousand and one way aspect the limited water resource making full use of, wherein implementing the film plantation of full shop at ground surface is more effective cropping pattern at present.This cropping pattern also is the planting patterns that present northwest, North China large tracts of land are promoted.The film plantation of full shop has the soil moisture conservation effect of increasing production but has also brought many inconveniences to plantation, because spread the film mulch film both sides press mold that can't fetch earth entirely, manual work is time-consuming, and labour intensity is big.The domestic two furrows that worked out are spread the film drag links entirely at present; Form is had nothing in common with each other, and various types also all respectively have advantage, but various type all adopts the great-leap-forward squeeze-film mechanism that fetches earth; This mechanism also is not very ripe at present, causes facility aspect dependability, all to exist some problems.Because the conveyer belt that great-leap-forward fetches earth and needs to install around on the moving belt pulley of principal and subordinate; Several native angle bar that send are housed on the conveyer belt, and driven pulley must be contained in the furrower rear, could the soil that furrower scoops up excessively be arrived the conveyer belt top; Conveyer belt need be with the position rotation in low of driven belt pulley thus; Ridge, both sides side soil also be prone to get between conveyer belt and the belt pulley, if when soil moisture content is higher, earth will soon be bonded on the belt pulley; Make diameter pulley constantly become big, conveyer belt snaps or goes out to draw back from joint the most at last.Angle bar on the conveyer belt rotates with belt pulley, and the angle bar connecting portion contacts with interior soil soil block and the hard thing of ditch for a long time, and angle bar is prone to come off from conveyer belt.In addition, field crops root stubble is more when big, and the root stubble also is prone to stop up and gets lodged in furrower and conveyer belt connecting place top, and the furrower top can occur equally stopping up and blocks up when soil moisture content is higher, thereby influences the facility operate as normal.
Summary of the invention
The object of the invention be to provide a kind of simple in structure, operate steadily, the rotary tillage ditching ridging of long service life spreads the film drag links entirely.
The present invention solves the employed technical scheme of its technical problem:
One kind of rotary trenching ridge full Filming casing machines, including racks, rotary knife, repression plastic wheels, trenching soil bodies, soil transport and distribution agencies and hanging racks, said rotary ditching borrow institutions Knife in the lower front of the rack; said soil transport and distribution facilities are in the middle rack, soil transport and distribution agencies, including soil belt, soil and soil movement guide plate diversion channels, soil belt in the drive pulley and the driven pulley between the outside of the soil with soil conveyor belt angle iron, a driven pulley connected to Cheongju processors, Cheongju soil belt located inside the processor.
Said frame is provided with the soil movement guide plate, and the soil movement guide plate is positioned at the rotary blade top.
Qing processor of said triangular shape.
Said soil movement guide plate is an arc.
The present invention fetches earth shovel trench digging and makes rotary tillage ditching into and fetch earth.Rotary blade runs into corn stubble, soil block and can root stubble soil block be smashed and throw to above the conveyer belt when trench digging fetches earth.When soil moisture content is higher, rotary blade still can get rid of earth above conveyer belt under centrifugal action, thereby has avoided the fetch earth heap soil or fertilizer over and around the roots of mechanism of trench digging stifled.With shovel trench digging fetch earth make rotary tillage ditching into and fetch earth after, the driven pulley of conveyer belt front lower place can be worked in the ditch and brought up to the ridge and work, thereby has avoided both sides, ridge soil to get into the conveyer belt inside front.Can all get into the soil conveying mechanism in order to ensure the soil that has revolved, this structure has been installed an arc soil movement guide plate in the conveyer belt top position, makes the soil that revolved drop on the conveyer belt top along the cambered surface tangential direction of soil movement guide plate.For reliable equipment, the equipment is also driven belt pulley is mounted inside the rear of a triangular Qing processor when turning the work belt, triangular scraper Qing processor and conveyor to the inside of the driven pulley obstruct removal of soil, but can also be involved in crop stubble rotating belt removal, improve the overall service life.
