Description

one

I Kobreteiie will respond to the region p.11) SC () of the household and can be used to determine the physical and mechanical properties of the fruit.

A device for investigating the co-motivation of fruits with cyclical loads is known, which contains a supporting table, a shock gab, a means for holding) to test: your fetus, software and recording equipment.

In order to increase the possibility of fixing various - according to the size of the fruit without first deforming, in the proposed device the means for holding the fetus is made in the form of a flat elastic element with concentric 1 notch in the central part for the part of the fruit that comes in contact with the body, and one end is elastic. The coping is fixed on the impacting head without movement, and the second one - by means of clamps.

FIG. 1 shows the proposed device, a general view; in fig. 2 — Shock head with means for holding the test fruit.

The device for the study of co-fetal co-load cyclic loads includes a choke-crank-type mechanism /, on the brush of which the shock head 2 is attached.

water rod-crankshaft mechanism / is realized from the electric motor 3. In the housing 4 on two sub-platforms, a shaft is installed, on one end of the KOTOpoio a stepped jaw J is fixed, on the other-m - an eccentric 6. The start of the electromotor 3 is produced by the switch 7 through the starting relay 8. Programmable time relay 9 is intended for receiving adjustable programs of operation of the device. To record the number of perfect cycles of the shock head 1, set the counter 10 number of revolutions, connected by a flexible shaft // with the end of the shaft of the stepped pulley 5. The 12 hour indicator serves to control the magnitude of the vibration amplitude of the shock head 2. Support table J3 for placement and securing the impacted body is adjustable in height. Pa blowHoii head 2 one end of the flat elastic element fixed still. All units and mechanisms of the device are located on three bases 75.

Prnbar works as follows.

The fruit 16 is covered with a flat elastic element 14 and pressed against the impact head 2. Then it is fixed with clips 17. Pa the supporting body 13 is fixed to the impact body. Programmable relay 9 time setup: -1ay for the defined period of work. .- The amplitude of oscillations is established by means of eiocene.tricase. The height of the olor table is 13, the water is located: on it is a striking body to the fruit 16 before the contact of their surfaces. The support table 13 is in this position secured. The count of 10 revolutions is set in 1pule; The motor 3 is turned on, and the fruit 16 is subjected to cyclic loads. After working off the required time schedule, the electric motor 3 is automatically switched off. In this case, the counter 10 of the number of revolutions fixes the number of cycles of exposure to the cylinder. The fruit is inspected and: the necessary measurements of the times of CPs and OB1 are expected.
