Abstract
The magnetic ploughshare is made up of carbon steel, chromium steel or cobalt steel through smelting, casting, heat treatment and then magnetization, and features low ploughing resistance, excellent mechanical performance, stable magnetic properties and low cost.
Description
The invention belongs to a kind of agricultural land soil tillage equipment.
Each the subject infiltration of modern magnetics forward, the domestic and international research data shows, externally-applied magnetic field is to the soil water potential of soil, improve the micelle kernel structure of soil, these variations will cause the reduction of plowing resistance, Agricultural University Of Shenyang once had been developed into hangs four ploughshare magnetized ploughs, this magnetized plough is the permanent magnetic device that installs high field intensity in the back of common four-share mounted plow additional, experiment shows, use this ploughshare to carry out farm work and can reduce plowing resistance 11.7%, reduce the tractor main fuel and consume 11.3%, but this magnetized plough also exists following shortcoming: 1, cost is higher; A four-share mounted plow needs more than 400 yuan of many investment at least; 2, the contradiction of the installation site of permanent magnetic device and field intensity is difficult to thorough solution.Because the mounted angle of ploughshare is less, for guaranteeing the ploughshare sword enough magnetic field intensities are arranged, permanent magnetic device should be tried one's best near the ploughshare sword, but the closer to the ploughshare sword, the easy more scraping of permanent magnetic device.3, install permanent magnetic device additional at the ploughshare back, be difficult to form effective space magnetic field, to the magnetization of ploughshare top and anterior soil a little less than.
The object of the present invention is to provide that a kind of cost is low, magnetic property and the better magnetic plow share of mechanical property.
Ploughshare of the present invention is made by the carbon steel with magnetic, chromium steel or cobalt steels.
Its manufacture method is as follows: adopt carbon steel, chromium steel or cobalt steels to make ploughshare through smelting, casting technique, again through Technology for Heating Processing, then ploughshare is magnetized.
Experiment shows, adopts above-mentioned magnetic plow share to have following advantage:
1, energy-saving effect is remarkable
Autumn is turned over the energy-conservation data table of comparisons of performance test
| The unit classification | Area (Nn) | Fuel consumption | The mu fuel consumption | Rate of economizing gasoline |
| Magnetic plow share | ????560 | ????450 | ????0.7633 | ???17.43％ |
| Plain share | ????450 | ????416 | ????0.9244 |
Magnetic plow share is than plain share fuel-economizing about 17.34% as seen from the above table, and energy-saving effect is remarkable.
2, mechanical property is good
The measuring mechanical property table

| Hardness HRC | ?42 | ?45 | ?50 | ?57 |
| Impact value kg/mm | ?0.0035 | ?0.0032 | ?0.0040 | ?0.0028 |
Find in the test, plough in operation season that under the same conditions, the contrast ploughshare is scrapped because of wearing and tearing whole, changed twice, and weight is 4750 grams before the magnetic plow share test, 140 mu plough operation after, weight is 3750 grams, still can use, this shows, magnetic plow share high abrasion resistance of the present invention.
3, magnetic property is stable, and the Distribution of Magnetic Field that produces helps the magnetization to soil.
Each magnetic plow share magnetic property table
