Description

The invention relates to devices for sampling grain in a branch pipe, consisting of two fist washers, seated on a common shaft and driven by a pulley. Washers are supplied with ratchet device. In the attached device, the valve opening fist sits on the same shaft with a washer fitted with a spring-loaded lever with a roller. The specified roller may engage with recesses on the inner surface of the rim of the drive pulley by removing the locking roller from the cut-out of the washer, using a cam washer.

In FIG. 1 is a side view of the device; FIG. 2 - front view; FIG. 3 - device diagram.

The proposed device for sampling grain in the branch pipe (FIGS. 1 and 2) consists of a ratchet wheel 5 receiving slow rotation from a pulley / through a ratchet device 2, 3, 4, and washers 6 fixed on a common roller with the help of dowels. A pulley 8, fitted on the inner surface of the rim of the recess 9, and a washer 9, having on itself, a spring-loaded lever / O with a roller 7 / and a fist 16 (FIG. 3) for periodically opening the valve, are freely seated on the same shaft. The pulley 8 is driven by the pulley 7. The corresponding notches of washers b and P include a locking roller 14, which holds both washers and lever 10 in place. To lift roller 14, which is sitting on lever / 5, which actuates the valve, the washer is used which, rotating at the same speed with the wheel 5, gradually removes the roller 14 from the notches of the washers. When the roller 14 is pulled out of the cut-outs of the washers, the lever 10, under the action of the spring 13, pushes its roller 11 into the recess 8 of the pulley 8 and, thus, the pulley 8 will be connected to the washer 9, as a result of which the latter will begin to rotate at the same speed Like the pulley 8, With one turn, the washer 9 with its projection will again drive roller 14 into the notches of both washers and deflect lever 10 to a non-working position. The washer 9 will remain at rest until the washer does not link it with the pulley 8.

The subject matter of the invention.

A device for sampling grain in a branch pipe consisting of two.

provided with cut-out knuckle washers sitting on a common shaft and driven in rotation by a pulley and ratchet device, characterized in that for opening the valve: with a fist / 5 the washer 9 that sits freely on the shaft is provided with a spring-loaded lever W with a roller // that can engage. with notches 8 on the inner surface of the rim of the drive pulley 8, by removing the locking roller / 4 from the cut-out of the washer 9, with the help of the cam washer 6.
