Description
Technical field
The utility model relates to a kind of agricultural machinery technological field, specifically a kind of transformation of maize harvesting machine.
Background technology
Maize harvesting machine is in the time that corn is ripe, according to its planting patterns, agriculture requirement, processes and gather in the work tool of the production links such as rear rotary tillage soil with mechanical stem cutting, harvesting, peeling, threshing, the stalk completing corn.One of them important step, the simple preposition field-returning machine of stalk processor, reaping machine and rearmounted field-returning machine stage have been passed through in stalk processing.If corn picker and stalk processor carry out respectively operation, so not only consuming time, and increase the weight of manual work amount, agriculture wonderful stage gradually has been eliminated out.In existing maize harvesting machine, mostly be preposition field-returning machine or rearmounted field-returning machine.And in existing maize harvesting machine, mostly being four-wheel drive device, preposition and rearmounted field-returning machine has a lot of deficiencies.Preposition field-returning machine, owing to being arranged on maize harvesting machine front end, has more the defects such as existing card stalk, obstruction, most importantly existing maize harvesting machine four wheel drive, and power transmission shaft transmits power backward, and preposition installation is still immature.Rearmounted field-returning machine is mounted in the rearmost end of corn picker, and can fall 7-8 rice during to the edge of a field at reaping corn machine operation can not chopping and returning, so just can not bring into play the effect of field-returning machine completely.But because existing corn picker four wheel drive, power transmission shaft transmits power backward, straw cutting apparatus can not be installed at central frame beam position due to the location of power transmission shaft.
Summary of the invention
For overcoming the defect of above-mentioned prior art, the utility model provides a kind of four wheel drive maize harvesting machine with mid-field-returning machine, can four wheel drive can settle at vehicle frame middle part again the grain header framework of straw cutting apparatus, thereby realize the perfect adaptation of grain header and straw cutting apparatus, made up the deficiency of preposition field-returning machine, rearmounted field-returning machine, also made up can not four wheel drive deficiency.
A kind of four wheel drive maize harvesting machine with mid-field-returning machine of technical scheme that the utility model adopts, comprise front two wheels, gearbox drive axle, power transmission shaft, field-returning machine, rear driving axle and rear two wheels, described power transmission shaft is divided into front propeller shaft, inter-axle shaft, drive axle gap bridge gear-box is installed between front propeller shaft and inter-axle shaft, drive axle gap bridge gear-box is mainly made up of upper transfer gear and lower transmissioning gear, upper transfer gear and lower transmissioning gear are by chain drive, lower transmissioning gear is fixedly connected with transmission one axle, transmission one axle is connected with front propeller shaft by universal joint, upper transfer gear is fixedly connected with transmission two axles, transmission two axles are connected with inter-axle shaft by universal joint, described field-returning machine is arranged on transmission one axle front, transmission two axle belows, the power of field-returning machine is provided by main frame engine, engine is by chain drive, drive the pinion of field-returning machine, pinion drives main shaft to rotate, main shaft drives the belt pulley of the main shaft other end, then drive field-returning machine driving wheel to rotate by belt.
Power transmission principle: described front propeller shaft accept gearbox drive axle power power transmission to drive axle gap bridge gear-box, described drive axle gap bridge gear-box will be accepted front propeller shaft power two wheels after inter-axle shaft and rear driving axle are transferred to.
The utility model has the advantages that: owing to straw cutting apparatus being arranged on to the middle part of maize harvesting machine, there will not be the defects such as card stalk, obstruction, overcome and be arranged on a front-end technology difficult problem, also while there will not be operation to the edge of a field, fall the deficiency that 7-8 rice can not chopping and returning, thereby overcome the disadvantage that is arranged on rear end, the large function of a grain header two is brought into play completely.Originally, power transmission shaft is one, the inconvenient straw cutting apparatus of installing at middle part, and two power transmission shafts before and after the utility model becomes, have reached the features such as fixed installation, the dynamic property of field-returning machine is strong, powder of straw fragility better effects if, thus be more conducive to straw-returning.Design science of the present invention, rational in infrastructure, easy and simple to handle, save labor, with low cost, be adapted at promoting the use of in maize harvesting machine.
