Because the northern area of China is drought for many years, water resources shortage, severe water and soil erosion, country widelys popularize conservation tillage.In the Ministry of Agriculture " conservation tillage engineering construction planning (2009-2015 years) ", require: in 2.06 hundred million mu in the Northeast plain ridge culture district 5,040,000 mu, 1.28 hundred million mu of West of The Northeast China Arid Sandy Areas 2,960,000 mu, realize conservation tillage.The Northeast is take ridge culture as main, and it has the effects such as drought-relief, waterlogging-preventing, raising ground temperature, uses area large.But a little less than the ridge culture conservation tillage gordian technique Study of Thin, the technology integrated horizontal is low.What used in present northeastward area mainly is band rotary tilling-type Ridge-till and No-till Corn Planter, 2BML-2(Z such as the production of the holy imperial agricultural machinery in Fuxin, Liaoning Province two factories) Ridge-till and No-till Corn Planter, and the 2BJM-4 type stubble-cleaning that the Heilongjiang Province produces is sowed combine, all adopt mode Treating straw, the root stubble of band rotary tillage, its cleaning effect is good, and anti-blocking ability is strong; But the rotary blade havoc soil aggregate of its High Rotation Speed is thrown soil, is got rid of soil seriously, has increased power consumption, the shortcomings such as the machine vibration noise is large, operating environment is poor, poor stability; And destroy former ridge and form new ditch, cause and emerge slowly, lose the advantage of ridge culture, be not suitable with the requirement of northeast ridge culture no-tillage seeding.In " conservation tillage No-tillage Maize Planter test shaping recommendation type in 2004 "; stalk amount≤0.6 ㎏/㎡ does not reach the level that Ministry of Agriculture's " no-tillage seeding machine type Selection Test outline " requires 2-6 month milpa stalk amount 0.8 ~ 1.5 ㎏/㎡ of the northeast rear leisure of (black, lucky, the Liao Dynasty) results, and no-tillage seeding machine facility trafficability characteristic not yet thoroughly solves.The technical matters of northeast ridge culture machinery no-tillage seeding, its core is the anti-blocking problem of breaking that keeps ridge shape, the i.e. optimization design problem of the corn rootstalk cutting device of no-tillage seeding machine.
Summary of the invention
The purpose of this utility model is for the problems referred to above, a kind of corn stubble breaking resistance measurement device is provided, can test the breaking resistance of different corn stubble physical characteristicss, for design, improvement and the evaluation of No-tillage Maize Planter provides scientific basis and method, easy operating, applied widely, simple in structure, cost is low.
The technical scheme that the utility model provides is as follows: it comprises frame, buncher and speed reduction unit, and its special card is: connect cutterhead at upper rack by cutter shaft, and at the fixing makeup torque speed probe of frame; Rotating shaft one end of the torque rotary speed sensor speed reduction unit that is in transmission connection, the rotating shaft other end of the torque rotary speed sensor cutter shaft that is in transmission connection; In the bottom of frame guide rail and leading screw are set; Between upper plate and the lower plate pressure transducer is set, is fixedly connected with screw and slide block below the lower plate, lower plate is assembled on guide rail and the leading screw by screw and slide block, and the clamping pliers is set on upper plate.
Good effect of the present utility model is:
(1) can test the breaking resistance of different corn stubble physical characteristicss.Suffered drag size provides test unit when studying multi-form colter breaking, and then for overall design, improvement and the evaluation of no-tillage seeding machine provides theoretical foundation, satisfies the needs of present stage no-tillage seeding machine research.
Power, rotating speed, the torque of the extension instrument (torque rotational speed meter) that (2) can utilize torque rotary speed sensor during to breaking tested.By level of torque suffered lateral resistance size can be in the hope of multi-form colter breaking the time; Suffered vertical direction drag size when the extension instrument by pressure transducer also can be in the hope of multi-form colter breaking.Test unit when work, the rotating speed of torque rotary speed sensor in its regulation range, the situation the when rotating speed of breaking colter meets the field actual job.
What (3) device was whole has good stability, the personal safety the during work of warranty test device, and the while easy operating, applied widely, simple in structure, cost is low.
