Moreover, the angular velocity of the stirring of the blade, controlled by the back pressure from the mass of the abrasive and the parts above the blade (at the moment of its release to the upper position) or through the use of the braking mechanism, will be slightly lower than the speed of stirring, of individual parts and abrasive grains, due to What they will get additional movement in the volume between the two blades. The cumulative (taking into account this movement and the angular movement of the blades themselves) will be a petal movement trajectory.

When a workpiece hits

A crankshaft 3 is mounted for rotation in them, on the neck of which a agitator is mounted with integral two-section blades 4 and stops 5. The device is equipped with an unloading mechanism 6 and a loading device 7.

The blades 4 (Fig. 2.) are mounted on the sleeve, which is placed on the neck of the crankshaft 3 with the possibility of turning. The crankshaft is assembled and fixed in bearings fixed in the side wall of container 1. Additional link 8 is attached to blade 4 by means of eyelets connected by axle 9. The stop element is rigidly fixed on additional link of blade and can mix in guide 10, made on the blade itself (Fig. 3). It can also be made in the form of a tail protrusion located both on the additional link (Fig. 4) and on the blade itself (Fig. 5).

The device works as follows.

The mass of abrasive material and parts located in container 1 (Fig. 1), by acting on it. The vibrator 2 is moved in the container along the path to the U-pattern forming the container wall. The mass of abrasive and parts under the action of inertial forces puts pressure on both links of the blade 4, ensuring their full (until it stops)

After unfolding and parts, it continues to press on the blade of the agitator, trying to deform the part and turn the agitator. This creates a moment of back pressure from the side of the jamming part, leading to a partial folding of the blade in the direction indicated in fig. 3, 4 and 5, which facilitates the passage of parts.

After the passage of the part, the link 8 returns to its original position up to the stop 5 under the action of inertial forces of the abrasive mass and details, thus ensuring the reliability of the device operation.
