Description

The invention relates to the construction, in particular to the determination of the properties of concrete and mortar mixes.

The purpose of the invention is to increase the measurement accuracy and reduce the size of the device.

FIG. 1 shows the proposed device, a general view in FIG. 2, view A in FIG. 1, in FIG. 3 is a section BB in FIG. one.

The device consists of a housing 1, a working body 2, which has a cavity 3. The mechanism for moving the working body 2 consists of a drive motor 4, transmitting rotation to the drive sleeve 5, which interacts through slots 6 with stops 7 of the shaft 8 connected to the working body 2. Case 1 is provided with a cup 9 installed in the cavity 3 of the working body 2 and connected to the nut 10. The electric motor 4 has a meter 11 of power consumption. Between working body 2 and housing 1, bearing 12c is mounted with disk 13. Carpus 1 is equipped with a valve 14 and a seal 15 between working body 2 and glass 9.

The drive sleeve 5 is rigidly connected to gear 16, mounted in bearings 17 and on it are two disc springs 18 and 19.

The device works as follows.

The rotation of the electric motor 4 through the gear 16 of the gearbox is transmitted to the drive sleeve 5, which, by rotating, causes the shaft 8 to rotate. Under the action of the disc spring 19, the threaded part of the shaft 8 engages with the nut 10, and the shaft 8 begins to make a forward-translational movement to the right. Together with him, the same movement is made by the working body 2, embedded in a concrete (mortar) mixture. After the full progress of the worker

Body thread on the shaft 8. is disengaged from the nut 10 and the working body 2 continues to perform only a rotational movement. When changing the direction of rotation of the engine under the action of the spring 18, the threaded part of the shaft 8 engages with the nut 10, and the shaft 8 begins to perform a rotational-translational movement to the left until the working body 2 is completely removed from the concrete mixture and the threaded part of the shaft 8 does not get out of engagement with the nut 10. During the movement of the working body 2 to the left, it is automatically cleaned from the concrete (mortar) mixture due to movement in the disk 13. At the same time, an excessive air pressure is generated in the cavity of the housing 1. Thu movement of the working member 2 into the housing 1, the presence of the seal 15 and closing valve 14 which opens at vschvizhenii working body 2 to prevent creating a cavity 1 housing discharge voltage. At this point, the cycle of operation of the device ends.

F. formula
