Description

Dynamographers are already known in the art, in which a movable clip holding the end of the test specimen is connected to a spring in order to record the developed efforts on the drum of the dynamograph.

In the proposed dynamograph, in order to exclude from the pa diagram of the chart recorder the magnitude of the force applied to the deformation of the sample, to obtain the force that characterizes, for example, the plant stem is pulled out of the soil, two indicators are attached, one of which is attached its compression, and the second to the opposite end and registers the linear deformation of the sample.

In FIG. 1 shows a general view of the device; FIG. 2-view of the chart obtained on the recorder; FIG. 3-7 are various adaptations to a dynamograph in order to expand its field of application.

The frame of the dynamograph is made in the form of a tubular stand / (Fig. 1), provided at the bottom of the fifth 4 with a pinch 2, immersed in the soil for stability. The rack is held in a vertical position by braces 23.

At the front, with the help of the brace 72,

drum 3 is attached to record the chart; the upper part of the drum is provided with a grooved wheel b, which is covered by cable 75. One end of the cable is attached to the cup 4, and the second, passage through the blocks 7 and S, pesetas cargo 9.

On CToiiKe 7, clamp 76 is fixed with the possibility of permutation, which serves to keep the load 9 from falling, and the stop ./, to stop the load at the end of it.

Inside the cup 4 is placed the JO JOURNAL, supported by its dissolution on the spiral spring. A cable 77 is attached to the rod W, and a clamp i J8 is used at the end of the latter, which serves to hold the test specimen (in this case, the stem of the plant).

On the glass there is one indicator 7Я and the second 20 is attached to the upper end of the JO rod. Both indicators are equipped with pencils.

The dynamograph operates as follows. After fixing the test specimen in the clamp 18 and setting the indicators J9 and 20 to the proper position, release the cable from the clamp 76. The released load drops down and begins to pull the cup 4 through the cable J3 upwards, rotating

The use of a bracket with a roller 25 (Fig. 6) will allow one to determine the force required to overcome friction between any material fastened on the plate 27 and the soil or other material on which the plate is to be laid.

Finally, the last use of the instrument is the determination of the display: if the density of the soil can be obtained by using a device, as shown in FIG. 7. This device consists of a bracket 28 fixed also on the tubular stand 7 of the device. KronuiieiiH this one is equipped with a yoke 29, having a shoulder length with a ratio of 1: 2. The ends of the rocker arms are equipped with arcs, representing a part of the circle described from the point of the rocker, as the center of the arm.

The short arm is connected to the ground; 77 with a dynamometer, while the long arm is connected by a cable 30 to a cylindrical rod 5 /. The rod moves freely in the guides 32 and under the action of the bolt. The cargo may be immersed in the soil}: a certain depth. The soil float will be determined by usi .I e; -; necessary for this dive, recorded on the iipnap chart. The obtained value, of course, can only be relative, as such, can be considered for setting the soil a different raft;: 0.

The diameter of the rod, as well as the shape cio of the submersible is the end soil,

must be set by experiment. Since the force curve recorded in the diagram will characterize the variability of the force during the entire immersion of the rod, it will be easy to detect any random resistances or voids in the diagram and to study such diagrams specifically or discard them.

The proposed universal dynamograph is particularly suitable for determining the physicomechanical properties of plants and soil and can be successfully applied in field conditions without the need for qualified personnel.

That may be of great importance. that all the determinations in this case can be made by the same methods and on the instruments of the same system, which allowed bu 1 to produce the corresponding comparisons and generalizations with sufficient accuracy and reliability.

The subject matter of the invention.

1. A spring dynamograph, characterized in that, in order to exclude the sample strain from the readings on the chart of the recorder, two indicators are used, one of which / 9 is connected to one end of the spring and the other 20 to the opposite one.

2. When using a dynamograph, the use of clamps 18, 21, 22, 24, blocks 25, and gears 29-30, which are used for determination 55, is known per se. Stretching of plants, tearing and squeezing, etc., and installed alternately on the stand / frame of the dynamograph.
