SU18576A1 - Grain Sampling Device - Google Patents

Description

In the device for sampling grain in the tolob or pipe adjacent to the mills or elevators, two valves are articulated with each other, one of which serves to block the outlet of the grain, and the other at the same time to keep the grain from going down in the open position first valve during grain discharging through the outlet.

In FIG. 1 is a side view of the device; FIG. 2 - its top view; FIG. 3 is a vertical section of it along the line AB in FIG. one.

The rotating pulley 1 (Fig. 1 and 2) is mounted on the shaft 2 with a worm 3, engaging with a worm gear 4 on the shaft b, on which a single-tooth gear 5 is mounted, driving gear 7 on the shaft 9 with an eccentric 8, with rods P in guides 10 connecting the eccentric 8 with the lever 1.2. The lever 12 end presses the lever arm 14 pivotally connected to the lever 17 pivotally connected in turn, the first (14) with the valve 19 and the second (17) with the valve 20 of the mill or elevator chute; the end of the lever 12 (toward the shoulder of the lever 14) is pivotally connected to the rest of the lever and is provided with a spring to pass when lifting it up at the end of the shoulder of the lever 14; the other end of the lever 12 by the springs 13 all the time is pressed to the eccentric 8. The spring 22 serves to bring the levers 14 and 17, and hence the valves 19 and 20 to their original position. Periodic rotation of the gear 7 and the eccentric 8 produces the corresponding pressing of the lever 12 on the lever arm 14 pivotally connected to the lever 17, as a result of which the valves 19 and 20 are raised, the valve 19 will open the hole for grain loading into the sample, and the valve 20 will keep the grain stream in the chute from moving along the latter for the time of dumping.

The subject of the patent.

1. A device for sampling grain, made in the form of an inclined chrome or pipe adjacent to grain elevators or the like, characterized by the use of valves 19 and 20 connected to each other, the first of which serves to block the grain outlet and the second detaining the grain from descending down ajar to its position at the moment of grain discharging through the outlet.

2. The form of implementation of the device indicated in Clause 1, characterized in that for opening the valve 19, serving as an outlet for the sample, and the valve 20, designed to restrain the flow of grain, the arms 14 and 17 are hinged between themselves to , for the purpose of periodically opening the valves, serves as a lever 12 connected by means of guides 10 to an eccentric 8 gear 7, connected through a single-tooth gear 5 to a gear 4, rotated from a worm gear, and to return the levers 14, 17 and 12 to the original field voltage are springs 22 and 13.
