Description
Affiliated technical field
The present invention relates to a kind of stubble collecting and returning machine, especially can realize playing stubble and going back the stubble collecting and returning machine of field function of stalk simultaneously, belong to agricultural mechanical field.
Background technology
At present, abolishing of corn stubble is the link that harvest corn operation in autumn presses for solution, when especially adopting corn combined harvester or during protective farming technique, needs especially to solve.Current, when harvest corn, generally adopted straw-returning, the stubble-cleaning operation is also few, mainly is because the problem of machinery.Even it also is the mode that adopts stubble-cleaning behind the field also that stubble-cleaning is arranged; Or field-returning machine and stubble cleaner separate operaton; Accomplish also field and stubble-cleaning operation respectively, also can form the stubble cleaner of returning crop stocks to the field, after returning crop stocks to the field, carry out the stubble-cleaning operation at once by field-returning machine and rotovator.This type machine is that straw cutting apparatus and rotovator are placed on machine (suspension type is at tractor) tractor rear portion (also have self-propelling field-returning machine is positioned over the machine middle part) basically; All there are tractor or the serious problem of combined harvester tire depression bar; It is relatively poor the straw chopping effect to occur; Can't satisfy the problem that agricultural requires, in order to improve operation quality, that part of stalk that is especially overwhelmed by tire; Need the field-returning machine moving knife of high-speed cruising from soil, it to be picked up chopping; With regard to the soil of cutting that must be serious, not only cause serious power consumption can cause that also the transmission system slip rate increases because of the obstruction of soil, causing cutting knife speed to descend influences cutting quality.
Adopt earlier and deliver in the field-returning machine of back with existing corn stubble has been dug together with the stem stalk of the corn rootstalk cutting device of rotation at a slow speed; Make the cutting knife chopping stem stalk and the root stubble of field-returning machine high speed rotating; Field-returning machine high speed cutter does not directly contact with soil; Thereby reduced power consumption, and guaranteed that the rotating speed of high speed cutter does not reduce, and has guaranteed operation quality.Solve the problem of wheel tire pressure stalk, realized also field stubble-cleaning institutional operation.
Summary of the invention
The purpose of this invention is to provide an a kind of stubble and and stubble collecting and returning machine of field function that can overcome above defective, can realize stalk simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stubble collecting and returning machine comprises gearbox, tripod, frame, crop plant cutter shaft, crop plant tool rest, plays stubble cutter, stubble breaking knife, returning device cutter shaft, goes back field cutter tool rest, goes back field cutter, stationary knife, case, depth control skid, stem stalk feeding mouth.Wherein gearbox is installed on the frame; Tripod is installed on the frame through the suspension ear, and crop plant cutter shaft level is installed on the frame, and the crop plant tool rest is arranged by spiral to be welded in and supplies to have installed stubble cutter and stubble breaking knife on the cutter shaft; Returning device cutter shaft level is installed on the frame; Also cutter tool rest in field is arranged by spiral to be welded on the cutter shaft and supplies to install also field cutter, and case is installed in the outside of returning device through frame, and stationary knife is welded on the anterior inboard of case; Depth control skid is installed on the case, and stem stalk feeding mouth is installed on the frame.During work, crop plant plays stubble, and all throws in the returning device together with stalk, goes back the field by returning device, has realized that facility carry out stalk with once advancing simultaneously and play stubble and also field operation.
Described stubble collecting and returning machine plays stalk batch function and forms a functional unit and the field functionalities lumps together, and crop plant plays stubble, and all throws in the returning device together with stalk, goes back the field by returning device.
Described stubble collecting and returning machine, crop plant tool rest (3) tilts towards deviating from crop plant cutter shaft (4) direction of rotation, with radially angle be 10 °; Playing stubble cutter (a 5) cutter type is left and right sides tulwar, and the blade mid portion is spiral of Archimedes shape, and the top is that circular arc is linear; Stubble breaking knife (2) cutter type is a straight knife; And blade is a spiral of Archimedes shape, and the layout of two kinds of cuttves is to divide 180 degree, symmetric arrangement in the same cutting plane; Crop plant tool rest (3) is arranged according to helix, plays stubble cutter (5) and stubble breaking knife (2) and arranges respectively.
Described stubble collecting and returning machine, crop plant blade axis rotary speed are 300r/min, and the returning device blade axis rotary speed is more than the 1000r/min, and the two all is a backwards rotation.
Described stubble collecting and returning machine is installed depth control skid and is carried out profiling on the returning device case, and the adjustable height of depth control skid.
The invention has the beneficial effects as follows; Stalk crop plant and returning device are combined functional unit of formation; Crop plant plays stubble; And all throw in the returning device together with stalk, go back the field by returning device, realized that facility carry out stalk with once advancing simultaneously and play stubble and also field operation; Crop plant tool rest (3) tilts towards deviating from crop plant cutter shaft (4) direction of rotation, with radially angle be 10 °, can effectively avoid twining grass; Playing stubble cutter cutter type is left and right sides tulwar, can dig crop root residue and also be transported in the returning device backward, and a stubble cutter mid portion is a spiral of Archimedes; The top is a circular arc line, has very strong sliding cutting effect and plays a batch effect preferably, and stubble breaking knife (2) cutter type is a straight knife; And blade is a spiral of Archimedes shape, has very strong sliding cutting effect equally, and the layout of two kinds of cuttves is to divide 180 degree in the same cutting plane; Symmetric arrangement, the crop plant tool rest is arranged according to helix, plays stubble cutter and stubble breaking knife and arranges respectively; The total length of cutter shaft and blade the revolution circumference on dispose blade equably, cutter shaft is stressed evenly during adjacent two blade works, cutter shaft does not shake when rotating; The crop plant blade axis rotary speed is 300r/min, and the returning device blade axis rotary speed is more than the 1000r/min, and the two all is backwards rotation, and is both energy-conservation, can the stalk of lodging all be thrown in the field-returning machine of back again and pulverize, and avoided leaking and cut; Depth control skid is installed on the returning device case is carried out profiling, and adjustable height, prevent that the power consumption that causes and the field cutter is directly beaten soil is excessive too fast with tool wear.
