Abstract

The invention relates to a shovel head shaking type stubble digging device and belongs to the technical field of agricultural machines. The shovel head shaking type stubble digging device comprises a shake generator, a rack, a connecting rod, a stubble digging shovel handle, a first hinge connecting pin, a second hinge connecting pin, a third hinge connecting pin, a fourth hinge connecting pin, a shovel handle fixing base, a grid bar type stubble digging shovel, an eccentric shaft, a power input chain wheel, a swing rod, a stubble digging shovel head, a shovel handle mounting groove, a hinged long groove, a swing rod connecting hole, grid bars and the like. The shovel head shaking type stubble digging device can simultaneously perform stubble digging, separation, clearing, collection, throw-conveying and straw smashing and field return operation at a time. First, the root stubble disposal problem is solved; second, the problems such as soil throwing and air pollution caused by the situation that soil exists on root stubble are solved; third, the problem that the straw smashing percent of pass is lowered because straw is pressed by tires is solved; fourth, only the grid bars shake, and thus power consumption is reduced; fifth, the problem that in order to improve the field return effect, power is seriously consumed and a tool is seriously worn because of high-speed rotary soil hitting of the field return tool, and consequentially the service life is very short is solved. The shovel head shaking type stubble digging device has the advantages of being high in smashing rate, small in power consumption, capable of effectively disposing the root stubble and the like.

Description

An a kind of shovel limb shaking digs a batch device
Technical field
The present invention relates to an a kind of shovel limb shaking and dig a batch device, can coordinate cleaning shredding mechanism complete collection and cleaning and the pulverizing of the digging stubble of stem stalk, broken stalk (lodging stem stalk) simultaneously and go back the functions such as field function, adopt shake to dig stubble and can greatly reduce the root stubble band soil amount of digging out, reduce that loss is raised in destruction to soil and throwing and the environmental pollution that causes thus etc., and spade is fixed, only have the shake of shovel head, reduced power consumption, belong to agricultural machinery technological field.
Background technology
At present; the straw chopping of lodging and the processing of root stubble are in the middle of farmland operation; an insoluble difficult problem; especially the chopping of corn stem and the going out except more outstanding of root stubble to lodge; be problem in the urgent need to address in harvest corn operation in autumn, when especially using corn combine results or adopting protective farming technique, there will be serious obstruction and affect operation; also can cause wheat emerge difficulty etc. problem, more need to solve as early as possible.In current corn results process, also the mode of field and stubble-cleaning integration of operation is little to adopt stem stalk, and the corn stem of lodging cannot mincing and returning to the field, and this is mainly the problem of mechanized equipment self design.Existing stubble-cleaning mode is to go back stubble-cleaning behind field, forms machine for returning stalk and cleaning stubble by field-returning machine and rotovator, after carrying out straw-returning, carries out stubble-cleaning operation at once, or field-returning machine and stubble cleaner separate operaton, completes respectively also field and stubble-cleaning operation.This class machine is stem stalk field-returning machine and rotovator to be placed on to machine (suspension type is at tractor rear portion substantially, also have and self-propelling field-returning machine is positioned over to machine middle part), all there is tractor or the serious problem of combined harvester wheel tire pressure stalk, cause stalk to be picked up by shredding mechanism, if shredding mechanism is too high apart from earth's surface, there will be serious leakage to cut, if too low, can cause again shredding mechanism to cut soil serious, except increasing power consumption, also can cause that the decline of shredding mechanism speed seriously causes straw chopping effect poor, also can in operation, stop up the problems such as machine and tool wear aggravation life-span shorten greatly, cannot meet agriculture requirement.
Summary of the invention
The object of this invention is to provide a kind of device that can overcome above defect, the shovel head that batch device digs by a shovel vibrating type in elder generation has dug crop root residue, and be transported to backward on grizzly bar, after according to spherical track shake, soil is separated with root, soil is shaken off to root stubble under grizzly bar is continued transported to shredding mechanism below below by shredding mechanism mincing and returning to the field, and an one shovel limb shaking of simultaneously realize digging stubble, trembling the function that soil separates, carries digs a batch device.
The technical solution adopted for the present invention to solve the technical problems is: an a kind of shovel limb shaking digs a batch device, comprises jitter generator, connecting rod, digs a batch spade, chain connection pin I, II, III and IV, spade holder and grid type dig stubble shovel etc.It is characterized in that: can support the use with self-propelled, suspension type combine harvester for corn; The shake of shovel head is dug batch device and is used in conjunction with cleaning shredding mechanism, and jitter generator is fixed in frame, drives eccentric shaft rotation by input sprocket, eccentric shaft is equivalent to crank, drive fork to swing by connecting rod, meanwhile, digging on stubble shovel at grid type is trough type with the pin-and-hole that is connected of spade, make shovel head except swinging, also play in the middle of elongated slot, the spherical swinging track of two motion blended spaces, to increase shake separating effect, only have the shake of shovel head, reduced power consumption; Shake is dug in batch device, digs a batch cutter and is arranged on bending spade, and grid type digs stubble and shovels the below that is positioned at cleaning plant and stalk crushing device in underground; When work, grid type digs stubble shovel and inserts underground, root stubble is dug out, and after root stubble is separated with soil, flow to the supporting low speed cleaning plant that is positioned at earth's surface, by digging out the root stubble of separation, stem stalk and the residual stalk of lodging picked up and thrown in the middle of the supporting shredding mechanism in rear along earth's surface, the crushing knife tool being rotated by shredding mechanism high speed adopt the mode of sliding cutting and with stationary knife to cutting after straw chopping, shed go back to also field, field.
The invention has the beneficial effects as follows, at corn stem also in the operation of field, this vibrating type dig batch device and cleaning, chopping and also field function combine and form the functional unit in ground, to maize straw and root stubble dig stubble, collect, chopping and also field integrated treatment.Specifically first by digging a batch device, milpa is dug out from field, thoroughly solve root stubble and processed problem, and effectively clear up by the rationally shake of this device the soil separating on root stubble, again by low speed rotation cleaning plant by the stem stalk of this plant and field lodging and stubble (be scattered field straw and the weeds etc. of causing because of a variety of causes, because be low speed cutter, be to cut soil, can not cause heavy wear yet) collect throw in shredding mechanism, by the chopping cutter of High Rotation Speed, (this cutter is away from ground again, avoid cutting soil) stem stalk and root stubble are shredded and go back field, the disposable stubble that simultaneously digs, separate, cleaning, collect, throw, stalk disintegrating and also field operation.The one, solve root stubble and processed problem; The 2nd, solve the problem such as throwing soil, air pollution that root stubble band is made with local methods; The 3rd, solve the stalk disintegrating qualification rate decline problem causing because of wheel tire pressure stem stalk; The 4th, the shake of shovel head, has reduced power consumption; The 5th, solve as improving field effect, also field cutter High Rotation Speed is beaten the problems such as serious and cutter heavy wear life-span of power consumption that soil causes is extremely short.
