Description

FIELD OF THE INVENTION The invention relates to auto feeders for fattening pigs in liquid and semi-liquid feeds with distribution through a tubular feed line.

The known auto feeders for these purposes allow liquid and semi-liquid feeds to be filtered from the feed line to the feed trough mainly due to the slow response of the valve mechanism, which can lead to loss of feed and its excessive consumption.

This disadvantage is largely excluded in the proposed automatic pig feeder, in which the inlet valve is designed as a cylinder with windows. This cylinder covers the output end of the feeding tube and is rigidly connected to the float. The float is attached to the feed line by means of an articulated multi-link mechanism. The multi-link mechanism is under the influence of a spring, contributing to its rapid transfer of its links with the float and valve from the neutral position to the upper or lower position, corresponding to the closing or opening of the valve.

FIG. 1 shows the proposed automatic pig feeder, side view, in axial section; in fig. 2 -klapap automatic feeders in the closed position.

The proposed pig pig feeder has a round or rectangular feeding trough 1, in the middle of which there is a float-valve device, connected through pipe 2 to the feed pipe 5. At the end of the pipe there are diametrically opposed windows. The valve is fitted on the nozzle 4, made in the form of a cylinder with the same windows. The valve is attached to the float 5, which is connected to the feed line using a multi-link articulation mechanism 6.

In the absence of liquid feed in the auto-feed vessel, the float together with the valve is lowered by its own weight. In this case, the windows at the end of the nozzle and in the valve cylinder match the feed.

naching1 enters the aft trough. As the trough is filled, the float rises and the windows at the end of the nozzle slowly close with a valve. At the same time, the spring 7 of the multi-link mechanism is compressed to stand against its rotary hinge rods 8.

Upon further raising of the float, the multi-link mechanism comes out of the neutral position and the valve quickly closes the windows at the end of the nozzle, since in this case the spring of the mechanism contributes to the raising of the float.

When the feed is consumed, the float with the valve is again lowered under the action of its weight, overcoming the tension of the spring of the multi-link mechanism.

Subject invention

An automatic pig feeder consisting of a feed line, a feed trough, a nozzle for connecting the feeder with a feed line and a valve device, characterized in that, in order to accelerate the actuation of the valve mechanism and thereby reduce the filtration of liquid and semi-liquid feeds at the exit of the nozzle in the trough, a valve, made in the form of a cylinder with windows and covering the outlet end of the nozzle, is rigidly connected to the float attached to the corona housing by means of a multi-linkage, which is under the action of a spring us, it promotes the rapid transition units from the dead position to the upper or lower and accordingly the instantaneous transfer valve with a float.
