Furrow ridging furrow plough is decided in a kind of rice stubble field
Technical field
The utility model relates to a kind of soil cultivating machine, and the furrow plough of furrow ridging is decided in especially a kind of rice stubble field that is applicable to, belongs to agricultural machinery technological field.
Background technology
Publication number is the Chinese utility application of CN101766093A, a kind of rape no-tillage place-transplanting total straw application high production high efficiency method is disclosed, the concrete steps of this method are: at first, directly on paddy field after the results, decide the furrow ridging with creeper, furrow face width 90cm, furrow furrow width 30cm, and form the ridge respectively in furrow ditch both sides; Then, the delegation's rape of planting in every furrow both sides, spacing in the rows 15~18cm is close to the ridge with Brassica campestris L seedling and puts, and with soil block at all; Again, straw is laid in (in the middle of the two row Brassica campestris L seedlings) on the furrow face, from the furrow ditch, fetches earth gland on straw.The major advantage of this rape method for planting, the one, the rape rice shoot is planted on the ridge of furrow limes marginis, can not be subjected to the stain evil; The 2nd, furrow face mulching straw can either reduce soil water evaporation speed, is beneficial to the Brassica campestris L seedling root growth, shortens seedling-slowing stage, can avoid rice straw burning to pollute, increase the soil organic content again, suppress weed growth; The 3rd, wide line-spacing, narrow spacing in the rows are planted, and ventilation and penetrating light is good, can reduce disease, convenient fertilising, the operation of spray medicine.Facts have proved, adopt this kind method rape of planting, can obtain highly efficient and productive, the effect of increasing income.
Use above-mentioned rape method for planting, at first be just to have gathered in the crops on the big heavy soil of back water content in paddy rice to decide the furrow ridging, and the both sides that require bulk soil to be deposited in the furrow ditch when opening the furrow ditch form the ridge, owing to also there is not to satisfy at present the agricultural machinery product of this instructions for use, have only employing manually to decide the furrow ridging with creeper, not only labour intensity is very big, and operating efficiency is very low, can only finish the workload of 0.07 hectare in artificial one day for one, thereby restrict applying of this advanced rapeseed cultivation technology.
Summary of the invention
The purpose of this utility model is at above-mentioned rapeseed cultivation method the requirement of furrow ridging to be decided in the farmland, proposes a kind of rice stubble field and decides furrow ridging furrow plough, thereby promote applying of rape no-tillage place-transplanting total straw application high production high efficiency method.
In order to achieve the above object, furrow ridging furrow plough is decided in rice stubble of the present utility model field, comprise plow frame, be installed in the two mouldboard ploughshare formula furrow ploughs on the plow frame, its improvements are: comprise also being positioned at the preceding group careless wheel component of furrow plough that described group of careless wheel component mainly formed by dialling grass wheel, movable jib and Support bracket; One end of described Support bracket is connected on the plow frame of described furrow plough front side, and the other end extends towards the front lower place; Described movable jib is born on described Support bracket, and has the left and right arm that lays respectively at described furrow plough both sides; The upper end and the Support bracket of described left and right arm is hinged, the lower end is installed left and right group of grass wheel respectively.
When furrow ridging furrow plough and tractor operation are decided in rice stubble of the present utility model field, be positioned at the preceding grass wheel of dialling of double-walled ploughshare formula furrow plough the cutted straw that is cut off on the ground is pushed aside to both sides, furrow plough can be deposited in Tu Fa the both sides of furrow ditch when opening the furrow ditch afterwards.
The utility model further improves, described movable jib is born on Support bracket by eccentric cam, being shaped on the described eccentric cam with the eccentric cam shaft is one group of adjustment hole that the center circumferentially distributes, described eccentric cam shaft and movable jib are hinged, and are connected by latch and the movable jib that passes pin-and-hole on described adjustment hole and the movable jib.Like this, movable jib is pressed against on the Support bracket by eccentric cam, can utilize one group of adjustment hole to change the high and low position of dialling the grass wheel, to adapt to the different trench digging degree of depth.
The utility model further improves again, also comprises the land wheel with elevating mechanism, and described land wheel and plow frame are connected.The effect one of this land wheel is to limit the trench digging degree of depth, the 2nd, and balance plow frame vertical direction is stressed, improves the stability of facility operation.
Use rice stubble of the present utility model field to decide furrow ridging furrow plough, can satisfy the cultivated whole ground requirement that the rape no-tillage place-transplanting total straw application high production high efficiency method is decided the furrow ridging, operation quality is good, production efficiency is high.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Shown in Fig. 1~2, the rice stubble field of present embodiment decide furrow ridging furrow plough by plow frame 1, left and right two groups of land wheels 2, dial careless wheel component and two mouldboard ploughshare formula furrow plough 7 is formed, wherein dial careless wheel component comprise dial that grass takes turns 3, eccentric cam 4, movable jib 5 and Support bracket 6.The back shaft of land wheel 2, Support bracket 6 and two plough arm mouldboard plow 7 are connected with plow frame 1 respectively.Particularly, an end of Support bracket 6 is connected on the plow frame 1 of furrow plough 7 front sides, and the other end extends towards the front lower place.Movable jib 5 have lay respectively at furrow plough 7 both sides left and right arm, a pair of group of grass wheel 3 is installed in the left and right arm lower end of movable jib 5 respectively, the upper end and the Support bracket 6 of movable jib 5 left and right arms are hinged.It is that the center one group of adjustment hole and the movable jib 5 that circumferentially distribute are hinged that eccentric cam 4 is shaped on the wheel shaft, and is connected by Fixed latches and the movable jib 5 that passes pin-and-hole on adjustment hole and the movable jib.Gravitate, movable jib 5 is pressed against on the Support bracket 6 by eccentric cam 4.
Furrow ridging furrow plough and four-wheel tractor operation are decided in the rice stubble field of present embodiment.During work, can regulate left and right two groups of spacings of dialling careless wheel component and two mouldboard ploughshare formula furrow ploughs 7 according to the wide requirement of furrow, once finish trench digging, decide furrow, the ridging operation, by adjusting the different adjustment hole of using on the eccentric cam 4, can change the high and low position of dialling grass wheel 3, to adapt to the different trench digging degree of depth.
Furrow ridging furrow plough is decided in rice stubble of the present utility model field, have simple in structure, cost is low, easy operating, advantage that operation quality is good, operating efficiency is artificial more than 20 times.Therefore, after the utility model is promoted application, will promote applying of rape no-tillage place-transplanting total straw application high production high efficiency method, and the development that promotes China's south rice stubble rape production mechanization is produced positive role.
