DEVICE FOR AGRICULTURAL RESEARCH mechanical strength of materials, particularly of bumps, FIELD

摘要

The invention relates to a technique of measurement, particularly, to devices for the study of strength characteristics of materials and can be used in agriculture and irrigation at scientific and engineering research. The technical result is to increase the informative value and reliability of the results of research of mechanical strength of agricultural materials to improve the structure of working bodies of agricultural machines from the results. An apparatus for investigating the mechanical strength of the agricultural materials, especially bumps, in the field, comprises a frame 1 on which is installed the axis 2 with a pendulum 3 provided with a holder 4 for mounting various elements working organs for destroying agricultural materials and configured to change the impact force by test specimen, and a recording device 5. pendulum 3 is rigidly connected with the axis 2 and is a telescopic rod with the holder 4 at the end and to be mounted thereon load 8, and the axis 2 is mounted on the frame 1 horizontally by means of two bearings 10, 11 rotatably therein and longitudinal movement, the pendulum is located between the supports 3, 10, 11, one of which is detachable 10. Furthermore, the axis 2 is provided with removable bushings 12 of the same diameter and different lengths, with their installation on the axle 2 in such a way that when the distance between the pendulum 3 and each of the supports 10, 11 of the sleeve 12 tightly mating with one another, stacked along the axis 2 between the pendulum 3 and each supports 10, 11 without a gap, wherein one end 13 of the axle 2 is provided with an arrow 14, with its longitudinal displacement along the axis 2, followed by fixation, and the limb 15 with the graduated scale of the recording device is mounted on the frame 1. The frame 1 is made in the form of interconnected beams at its upper part two identical n- shaped supports, which are fixed onto the soil surface by means of screw pins 7. NRM f-ly; ZP f-ly; 2 yl.
