Description

A kind of multiple operation sower

The utility model relates to sower, particularly handles the multiple operation sower relevant with tillage operation with results back stalk.Belong to seeding machinery.

With China North China grain growth belt is two batches of multiple cropping cropping patterns of field crop of representative, and quite nervous when the summer harvest, autumn harvest two subjobs, particularly results are many with the link that overlaps of seeding operation, operation intersects, the manpower anxiety, the power anxiety, the time is more nervous.As handling wheat straw behind the summer harvest harvesting wheat, plough whole ground, sow corn then; Apply fertilizer, sow wheat after will handling stalk, whole ground during autumn harvest behind the harvest corn.The mechanized that has will successively be used straw cutting apparatus, tractor plough, rake, ridging machine, applies fertilizer at last, sows.Secondly being pressed for time is unfavorable for robbing farming season, and facility enter ground often, to soil stir, number of machine passes is many, causes the evaporation of water in soil and soil compaction, be unfavorable for emerging and plant growth.Cargo handling operation is many besides, has increased power demand quantity and power consumption, causes operating cost to increase, and becomes two big bottlenecks of restriction farm working machinery development.Therefore uniting compound working tool is developing direction.Particularly no-tillage seeding is advocated in some place in recent years, the also corresponding no-tillage seeding machine that stalk processing or scarification equipment back have occurred sower is bound up on.As CN1383923A disclosed " crushed stalk no-tillage with straw mulch seeding and fertilizer spreading machine " and CN2543329Y disclosed " with the no-tillage seeding machine of vertical straw millstone ", on addressing the above problem, obtained certain progress.This shows that multiple operation is the important development direction of sower from now on.But existing technology also exists body long, and shortcomings such as complex structure are not also really handled sowing organically combining with preceding stubble.Its key is, so far also solves well without comparison technically under the results back exists a large amount of straws, weeds and root stubble on ground the situation and finishes the sowing problem, mainly is to solve the problem that straw, weeds stop up plough.

The purpose of this utility model is to provide a kind of sowing and crushed stalk or tillage operation to organically combine becomes a machine, overcomes the multiple operation sower of straw, weeds obstruction plough problem.

The purpose of the utility model multiple operation sower realizes that by following measure this multiple operation sower comprises frame, gear-box, roller, feed mechanism, grain tube, plough, wheel mechanism.Gear-box, roller, feed mechanism are installed on the frame, connect grain tube under the feed mechanism, frame connects by suspension arrangement and tractor, drive roller by gear-box, roller can be installed straw stalk pulverizing knife or the rotary tillage weak cutter that goes out, the ground wheel mechanism drives feed mechanism, and its characteristics are that the installation position of grain tube and plough handle is to pass through between the gap of roller blade, and the blade of grain tube or plough handle both sides is straight shape impurity-discharging knife.

From the practice of seeding machinary integration of operation in the past, no matter be the summer harvest or autumn harvest, sowing has a large amount of stalks, weeds on the preceding ground, must handle, otherwise stalk is jammed in the seed-furrow opener place.Use disk coulter, meet stalk and be difficult to bury, almost can't operation.Here it is causes the foregoing reason weak, that put in order operations such as ground of must going out.From the operation principle of existing crushed stalk roller, the knife section of roller high speed rotating and the combination of stationary knife reach the purpose of crushed straw again.But stationary knife does not twine grass or straw clogging.This principle of utilizing the utility model realizes compound sowing, fertilising operation.Key is that plough, grain tube pass through between the blade of high speed rotating, be it is believed that it is impossible realize always.In fact, plough handle or grain tube pass through in the gap of rotating blade, if having straw, weeds to be blocked in therebetween, under the effect of impurity-discharging knife, are forced to rapidly get rid of, and can not stop up.The in a single day instantaneous extension grass of plough also can be removed clean by impurity-discharging knife at any time effectively.According to experience in the past, even if through sowing behind the whole ground, plough is still often hung grass and is stopped up.Iff the pulley type impurity-discharging knife being set in order to prevent plough from stopping up, increased machine complexity, " cost " paid some is big.Yet, when satisfying the stalk crushing and returning requirement, solve plough and hung careless blocking problem, just become ingenious and rational the design.The most suitable no-tillage seeding of being advocated in recent years promptly under the synergy of cylinder and plough, realizes that promptly the straw pulverizing has overcome plough again and hung grass, blockage problem.Plough just can reduce as far as possible finish under the situation that soil is stirred sowing, the fertilising and the suppression.Stalk, the weeds thrown by roller are dropped on again and have broadcast on the face of land, also play the soil moisture conservation effect.This has just realized " no-tillage operation " truly.If get used to old tillage method, drum speed is reduced, change the weak cutter that goes out, also can go out and finish sowing in weak, apply fertilizer in rotary tillage.Like this, the utility model just can be finished two even several the operations that facility can be finished several times by the one-stop operation after results of a multiple operation sower, for reducing soil packing and destruction, keeps soil moisture, improves tillage condition; Reduce and reduce the operation number of times with advancing, reduce operating cost and play an important role.
