Reciprocating Harrow Design And Experiment

Reciprocating harrow duplex working machine is to use the plow and rotary cultivator loosen the joint production of tillers,the overall structure is the former plow,rotary tiller home after.Four front-end plow plowing the soil,the soil break the rear end of rotary tiller,smooth surface after plowing,while capable of shredding plant stubble,easy planter operations,provide a good seed bed as late sowing.Position than the rear end of the front rotary offset machine four plow right,can better be deep plowing the clods break,loosen.Conventional tillage soil tillage operations overlooked finishing and seed bed preparation is important as a production base,resulting in food production can not be increased or cut,in order to continue to cultivate the land to maximize the effective protection,so that high-yielding crop yield,achieve maximize production efficiency,aiming at the technical requirements of maize straw: the straw crushed finer,deeper tillage,straw and soil mixture evenly,developed Reciprocating harrow duplex working machine,the prototype portion of the rotary plow land preparation continuous part of the job,covering close and can be adjusted according to the plots conditions,managed to complete the deep and pulverizer two jobs,job requirements maize straw.And improve operational efficiency,reduce the number of times into the ground.Joint development work more equipment,both to increase productivity,but also play to the performance of the tractor.Reciprocating harrow design and three-dimensional modeling duplex working machine main parts,including the plow,rotary tiller assembly,gearbox.Through research and agronomic requirements according to Anhui Province,to determine the specific size of the blade materials and components,complete virtual prototype model and machine assembly.Applying principles of organization,the three-dimensional model in CATIA import into ABAQUS in statics analysis,modal and frequency corresponding to one to ten bands subsoiler pear shelves and plow through analysis of the deep pine pear shelves and plow body kinematics and dynamics,verify the reasonableness of the agency.The use of related equipment,for the whole experimental modal analysis method by hammering obtained before 14 Order experimental modal frequencies and mode shapes results in Fig.,And through the coherence function method to test the quality of the test data,drawn its work to avoid the occurrence of a resonance phenomenon.Modal test analysis reciprocating harrow,Reciprocating harrow structural optimization analysis,design provides a theoretical basis for guiding verify the correctness of its natural modes.According to the theoretical analysis performed prototype trial,and two field trials,which are reciprocating harrow duplex operating machinery straw effect tests and different tillage sowing methods(Reciprocating harrow)physical and chemical properties of soil and crop yield impact test.The results showed that treatment Qiancha leave stubble and straw removal acres chattels NTC highest seeding integration,up to 661.1kg;for 1Reciprocating harrow and rotary fertilizer sowing integration followed.Qiancha straw under conditions,both to ensure the flatness of the soil after tillage can better reduce the weight of the whole production is expected to achieve a good structure.
