Description

Trench digging, fertilising, rotary tillage, sowing all-in-one

Technical field

The utility model relates to a kind of agricultural machinery, refer in particular to can ditch simultaneously, the farm equipment of fertilising, rotary tillage, sowing.

Background technology

In agricultural production, to wheat, barley and highland barley, plot in the Soybean and Other Crops sowing process is ploughed whole, applying of fertilizer, broadcasting sowing and earthing and suppression of seed, the work that is absolutely necessary of the excavation of drain ditch in the field, its usual way has two kinds: a kind of mode is that operation break-down is interrupted operation, the concrete course of work of this mode is for to be spread on the surface, field by manually shedding mode with fertilizer, by farm cattle or rotovator rotary tillage is carried out in the field again, then by manually sowing seeds, earthing and suppression, excavate the drain ditch at last, this mode is owing to adopted artificial, labour intensity is big, production efficiency is low, uneven sowing is even, and fertilizer is exposed to the volatile loss of overlong time on the face of land, in addition farming season the manpower anxiety, easily stop over farming season, influence grain yield; Another kind of mode is for adopting man-machine mixture operation, the concrete course of work of this mode is for passing through artificial broadcast application, after carrying out operation by the machinery that has the double sowing function of rotary tillage then, carry out the excavation in drain ditch again, owing to used machinery, it is artificial to have replaced part, and production efficiency is improved on the one hand for this mode, it is the operation break-down operation manually and still that this but then mode is not substituted by mechanical work fully, and production efficiency is difficult to be further enhanced.

The utility model content

Technical problem to be solved in the utility model provides a kind of high efficiency, and is simple and reasonable, integrates trench digging, fertilising, rotary tillage, the sowing all-in-one of multiple farmland operation.

In order to solve the problems of the technologies described above trench digging of the present utility model, fertilising, rotary tillage, the sowing all-in-one, comprise frame and be loaded on transmission case on the frame, and include kind of a case, seeding control assembly, the seeding apparatus of discharging tube and include rotary tillage shaft, the rotary cultivator attachment of rotary blade, be arranged at the earth level(l)er of rotary tillage shaft rear side, what be connected with the seeding apparatus lower end starts device, be arranged at the covering device of starting the device rear side and the press wheel that is arranged in parallel with rotary tillage shaft, adjacent side at described kind of case is provided with fertile case, this fertilizer lower box part is provided with the fertilizer expelling shaft assembly parallel with rotary tillage shaft, this fertilizer case bottom surface is connected with a defertilizing tube at least, and fertile case is connected with defertilizing tube; Rotary blade on the described rotary tillage shaft along axis direction in the shape of a spiral shape arrange, rotary blade about dividing on the rotary tillage shaft two sections, this rotary blade rotation direction of two sections is opposite.

After adopting said structure, because the adjacent side at kind of case is provided with fertile case, after the fertilizer expelling shaft assembly control of the fertilizer of in this fertilizer case, placing through being arranged at fertile case bottom, be guided to the inclined to one side front side, top of rotary plow and drop on the rotary blade by the defertilizing tube that is connected with fertile case, shed out equably and be mixed in by in the soil after the rotary tillage by the rotary blade that is rotating, realized mechanized application, guaranteed the uniformity of fertilising so on the one hand, reduced on the other hand because of manually shedding the overlong time that makes fertilizer be exposed to the face of land and caused the loss of volatilization, save production cost, improved production efficiency; Again because the rotary blade on the described rotary tillage shaft is arranged twist, rotary blade about dividing on the rotary tillage shaft two sections, these two sections rotary blade rotation directions are opposite, when carrying out the rotary tillage operation, can twist soil in the lump like this, realized that promptly soil can move to the rotary tillage shaft two ends along the hand of spiral of rotary blade in rotary tillage, the soil of eminence can be moved to fill and lead up the depression to low-lying place, fully guaranteed the plot flatness after the rotary tillage.

Again owing to be provided with furrow plough, then the effect by this plough can plow a drain ditch at the axial middle part of rotary tillage shaft, and the earth that plows is not through rotary blade effect on the rotary tillage shaft can be trapped in the drain ditch to the passing of machine both sides by, eliminate the earth of leaving and weighed the hidden danger that falls into the drain ditch earlier and stop up the drain ditch, guaranteed the unimpeded of field water system, this device and fertilising, rotary tillage, the seeding apparatus of will ditching carries out effective compound mode, and the earth has improved operating efficiency.

Again owing to be provided with cutting grass knife, this cutting grass knife can and buriedly cut off in underground foreign material weeds, makes that the cutting edge of furrow plough is unlikely at work to be curled up by weeds and foreign material, thereby has fully ensured the operate as normal of furrow plough.

In a preferred implementation of the present utility model, be horizontally arranged with a plurality of dividing plates on the inwall of described fertile case bottom.Adopt this structure to make fertile case bottom form a plurality of isolated spaces on the one hand, avoid under the less situation of the plot operation fertilizer that tilts, fertilizer is heaped to casing one end, and the other end does not have fertile phenomenon, makes unevenness of application, and the situation of fertilise occurs leaking; Processing on the other hand, maintenance all can be carried out easily.

In another preferred implementation of the present utility model, described fertilizer expelling shaft assembly is two sections, adopt this structure on the one hand the fertilizer control section is matched easily with the machine of wide cut, the difficulty of having got rid of slender axles processing in the mechanical processing process, on the other hand can to the fertilizer in the fertile case realize segmentation control promptly wherein arbitrary section fertilizer expelling shaft assembly work then the fertilizer of this side will be discharged, the fertilizer that two sections fertilizer expelling shaft assemblies are all worked in the then fertile case will all be discharged.

In a preferred implementation more of the present utility model, described fertilizer expelling shaft assembly is one, adopts this structure can be easily to match with machine in a narrow margin, and assembling is safeguarded all very convenient.

In further preferred implementation of the present utility model, described rotary tillage shaft is two sections, adopts this structure on the one hand the fabric width of machine is expanded, and increases the area of single work, adapts to the needs of big plot operation; Can adjust the angle on rotary tillage shaft and ground on the other hand according to features of terrain easily, make the soil of ground level after the drain ditch inclination tiltedly the is convenient to rain draining fast after the rotary tillage, reduce field humidity, provide a good growing environment to crop.
