Abstract

SUMMARY OF THE INVENTION: a feed distributor is provided with a feed pipe 1 with unloading internal 2 cylinders and external 3 metering cylinders. The feeders are located under the outer cylinders. The device for feeding feed to the feeders is in the form of a tray 5 in the shape of a parallelepiped. The length of the greater side of the base of the tray is determined from the ratio:

Description

The invention relates to agriculture, in particular to devices for the dosed delivery of bulk feed to animals.

The purpose of the invention is to reduce material consumption and expand functionality.

In FIG. 1 is a side view of a feed dispenser for dispensing bulk feed; in FIG. 2 is the same, view along arrow A with the control lever removed; in FIG. 3 is a diagram for determining the length of a tray; in FIG. 4 is a diagram for determining tray height.

A device for dispensing bulk feed includes a transport pipe 1 with a feed member. Near each animal, a cylindrical container 2 is fixed to the transport pipeline, onto which a cylindrical container 3 is coaxially mounted, the upper end of which is pivotally connected to the forked arm 4. Coaxially located cylinders 2 and 3 form a measuring container. With the help of the lever 4, the outer cylinder 3 can be moved up and down relative to the bottom of the tray 5, which on the one hand is pivotally mounted at a certain distance on the suspension 6. and, on the other hand, is suspended through a roller 7 to a flexible cable (cable) 8. Under the tray there is a guide bell 9 and a feeder 10. The end of the lever 4 is fixed on a graduated scale 11.

The device operates as follows. Before the distribution of feed is started, the operator sets the dispensing rate on the graded scale 11 using the lever 4. When the end of the lever 4 is turned down, the fork turns upward and pulls out the outer cylinder 3. The distance to the bottom of the tray 5 is increased and a large dose is poured into it stern. When the end of the lever 4 is turned upward, the cylinder 3 is lowered down, the distance to the bottom of the tray is reduced and a smaller dose of food is poured into it.

After adjusting all the dispensers to a specific dose of final feed to each animal, the operator turns on the working body of the transport pipeline 1, which fills it with feed. At the same time, the bulk feed enters the cylinders 2 and 3 of the measuring container and then pours out onto the bottom of the tray 5, being positioned at an angle of repose.

Then the operator stops the working body of the transport pipeline and releases the flexible rod 8. Under the influence of its weight and feed, the tray overturns (in black

is shown by a dashed line) and the feed in the measuring container and tray is poured through the bell 9 into the feeder 10. Pulling the flexible rod 8 to the left, the operator sets the bucket to its original horizontal position and is ready for the next cycle of operation.

The proposed device is simple in design and allows a large range to be dispensed to animals in both the upper and lower rivers.

The minimum tray length is determined from the circuit shown in FIG. 3. It can be seen from the diagram that the minimum length of the tray will be equal to the large diameter of the truncated feed cone, which is located on the bottom of the tray at an angle of repose, with the top cylinder located at a distance of maxax of its lower edge from the bottom.

It can be seen from the diagram that the minimum tray length is:

I-2C + D, (1)

where O is the diameter of the outer pipe.

The segment C is determined through Pmax and the angle

From the diagram (Fig. 4), we determine the minimum height of the rectangular tray for a given width B of the tray:

The segment K is determined through the minimum length I and a given width B of the tray:

Substituting expression (5) into expression (4) we obtain the minimum height of the tray at a given width:

It has been experimentally established that at the moment the feed is poured into the tray with a minimum length and height, part of the feed is sent from the tray.

We determined that there would be no partial spilling of feed from the tray at the time of loading, its dimensions obtained analytically should be increased by 30%.

Then the final expressions for determining the optimal length and height of the tray at a given width are given by:
