The drawing shows a silo-installation.
The silage assembly contains a frame 1 on which a frame 2 is installed, consisting of vertical columns 3, connected at the bottom with a support ring k and at the top with a slab 5. To plate 5 it is freely suspended on tension cushion springs 6 and an exemplary dynamometer 7 stretching the upper traverse 8 of an additional frame 9. On the upper traverse, on spherical hinges 10, rods 11 are installed, which with a gap are passed through the holes 12 of the support ring and at the bottom are fastened by a lower traverse 13, on which is placed a glass with a spherical bottom inside. The 8 cylinder is inserted into the hydraulic cylinder 15, the end 16 of which is made on the sphere and is adjacent to the sphere in the glass. A test dynamometer 17 of compression is fixed on the rod of the hydraulic cylinder and abuts against the support ring from below. A compression spring 18 is mounted on top of the support ring, on which the upper traverse is supported. The silometer installation is designed for graduation of dynamometers 17 for compression (force sensors) with a force range of 1; ten; 25; 50; 75 and 100 i.e. Each range of forces corresponds to its own hydraulic cylinder 15 and an exemplary tensile dynamometer 7. Their masses are different; therefore, the compression spring 18 is made exchangeable, with forces corresponding to the masses of the hydraulic cylinders 15 and tension dynamometers 7. The load capacity of the spring shock absorbers is such that the sub-frame 9 is in a suspended state. Spring 18 force squeeze

The suspension cylinder 15 with the dynamometer under test, a cup and an exemplary dynamo ™ meter 7 are suspended in a suspended state. Thus, the total carrying capacity of all shock absorbers and springs is such that they keep the moving parts of the installation in suspension.
The silage installation works as follows.
In the hydraulic cylinder 15, line 19 supplies the working fluid under pressure. Under the action of pressure, the piston of the hydraulic cylinder moves and presses the tested compression dynamometer 17 to the support ring k, as a result of which the additional frame 9 simultaneously moves and acts on the model tensile dynamometer 7 from which the readings are taken. Calibration of the dynamometer 17 is performed at different pressures of the working medium in the hydraulic cylinder. Each pressure corresponds to a specific force on the compression dynamometer under test, the values of which indicate the reference tension tensile tester 7. In this case, all moving masses are de-weighed by springs 6 and 18 and do not affect the readings. The spherical hinges 10, the spherical end 16 and the sphere in the glass 1 allow the rods 11 to take a vertical position parallel to the axis of the exemplary tensile dynamometer 17, as a result of which the hydraulic cylinder 15 is coaxial with the compression dynamometer 17.
The de-weighting of the moving parts of the silojining unit improves the precision of the calibration of compression dynamometers. The use of springs as anti-idling elements simplifies the operation of the stand. The use of one model tensile dynamometer located in the center instead of a few
exemplary compression dynamometers located at the periphery increases the accuracy of setting loads and controlling them. Making the bearing surface of the hydraulic cylinder over the sphere and installing it in a return cup, as well as hinging the traverse rods in an additional frame, compensates for technological inaccuracies in the manufacture of the installation and thereby improves the calibration accuracy.
