FIELD: agriculture.SUBSTANCE: device for silage sampling comprises a probe with a sharp-edged cutting edge in the lower part, a flange in the upper part, which is rigidly attached to the bar with a measuring scale, and a sample extractor. The probe 1 of square or rectangular cross section is provided in the lower part with two sharpened cutting edges 2 in the form of a dovetail. In the upper part the probe is provided with two fixing holes 3 providing its attachment to the flange 4 of the square or rectangular cross section by means of its spring-loaded clamps 6. For smooth transition from the square section of the probe 1 to the circular, the rod flange 4 in the upper part is made in the form of a truncated pyramid 11. The rod consists of bars 10 of circular section screwed into each other, with measuring technological holes 12, applied on its surface after every 100 mm. In these holes on the rod with the pin 15 a device is fixed, consisting of a sleeve 13 with two handles 14, and the extractors of the sample from the probe is the upper part of the rod, the diameter of which is less than the internal dimension of the probe.EFFECT: reduction of labour intensity of sampling due to easier penetration of the device in the estimated mass, providing the possibility of batch selecting at a depth of 1,5-2 m.5 dwg |
