This invention relates to the mechanization of animal husbandry and can be used in systems for removing liquid manure from animal houses.

The purpose of the invention is to simplify the design and operation, as well as to eliminate the consumption of flush liquid.

FIG. 1 shows a slurry device, top view; in fig. 2 shows section A-A in FIG. one.

The device includes trays 1, which are made in the floor of the cattle-breeding premises, and are closed with gratings 2 on top and equipped with gates 3 at the exit. Trays are made with a slope 005 ... 0.01 towards the gates. Trays 1 are adjoined by a transverse collector 4. The end sections of trays 1 are communicated by means of a horizontal channel 5, whose width is 0.7 ... 1.0 times the width of the tray. The bottom of channel 5 is located at the level of the bottom of the trays, and the height h is equal to 0.2 ... 0.3 of the height I of the trays in the end part. Gates 3 are made in the form of flat shields moving in grooves 6 located in the walls of the trays.

The slope of the bottom of the trays within the range of 0.005 ... 0.0 provides the required mode of operation of the device when performing trays of a length of 20 ... 50 m. When the slopes of the bottom are less than the specified values, the speed of the liquid is not necessary, and with large slopes the depth of the trays in the face plots is reduced, which leads to a decrease in the volume of accumulated liquid here, and, as a consequence, a decrease in the efficiency of the device. The height of the channel is chosen from the need to prevent the flow of suspended layer of manure from one tray to another with different feed rations and, accordingly, different height of the suspended layer. For example, when feeding pigs only with factory finished feeds, the suspended layer is practically absent, and when using coarse and succulent fodder in the ration, the height of the suspended bed increases.

It was established experimentally that the height of the channel, 2 ... 0.3 heights H trays. The smaller height provides the necessary intensity of the flow of the liquid fraction from one tray to another, and with a large one there is a free flow of the liquid fraction without flushing of sediment in the tray.

The lower and upper limits of the channel width (0.7 ... 1.0 tray width) correspond to the upper and lower limits of its height, which is justified by the need to ensure the required flow of liquid fraction through the channel for effective flushing of the trays.

The device works as follows.

Before manure starts, trays 1

when closed, the gates 3 are filled with water

so that the bottom is covered with a layer of at least 5 cm. After that, manure begins to flow into the trays 1, which the animals take over the grates 2. 5 residues of feed and technical water from the self-dumping system are received here, after washing the corsets, etc. As the dung mass accumulates in the trays, it separates to form a sediment, a layer of liquid fraction and a raised layer.

After filling the trays 1, one of the tweezers 3 is opened and the manure from the corresponding tray begins to flow into the transverse collector 4. When

Level 5 of manure in this tray begins to flow into it the liquid fraction from the second tray (the schiter is closed) through channel 5, which helps to remove sediment and suspended layer deposited on it. Emptying the first tray continues until the level of manure in the second tray begins to fall in the area adjacent to the gate. In this case, about 20% of the liquid fraction flows from the second tray to the first, which, depending on the tray size, is 4 ... 8 m. This amount of liquid fraction is sufficient to effectively flush the first tray. After this, the spike of the first tray is closed and the second tray is opened. When the emptying process of the second tray is completed, the gate is closed. The subsequent emptying of the trays is carried out in reverse order, i.e., the gate of the tray that was previously opened second is initially opened.

Thus, by alternately rinsing the trays connected to each other through the channel 5, the need to use flush water is eliminated, regardless of the type of feed used.
