DEVICE FOR THE AUTOMATIC ADJUSTMENT OF THE CUTTING PLATFORM POSITION AT GRAIN HARVESTING MACHINES |
摘要 |
<p>A device for the automatic adjustment of the position of the cutting platform of a grain-harvesting machine has a hydraulic cylinder attached both to a harvester body and to the cutting platform, the cylinder being supplied with oil under pressure from a pump by means of a differential distributor driven by feelers (sensors) mounted at the ends of the cutting platform. The differential distributor of the device , according to the invention is made up of a body provided with holes by means of which the distributor is connected to the pump to an oil tank and to the cylinder; inside the body, a casing and a plug are mounted. The casing is provided with holes which when the cutting platform is parallel with the soil register with holes in the plug which has a diametral channel, and with peripheral channels through which the oil passes when the cutting platform is not parallel to the soil.</p> |
