Suomi-Finland (FI) (7 * 0 Yrjänä Vuori (5M Automatic Feeder - Automatic Matrix)

Automatic animal feed rations have been developed in many ways to minimize the number of working hours.

One such automatic feed dispenser is based on a scale on which the feed flowing from the feed chute is weighed in the weighing tube and when a predetermined amount of feed has been spilled into the tube, the horizontal device closes the chute drain opening. The scale is a conventional-shaped arm scale with steplessly displaceable counterweights for the articulated bracket, which weight is usually tightened on the arm with a screw. The disadvantage of such a scale is that it. the joints are very easily contaminated with dust from the feed, which stiffens and disrupts the operation of the scale. Counterweight adjustment is also cumbersome due to screw tightening and may even loosen the screw and shift the counterweight.

In addition, a balance device such as that described is quite valuable.

The scale device according to the present invention is simple to manufacture and eliminates the disadvantage described above, being mainly characterized in that the suspension rods of the scale are replaced by a flexible rope or wire and that the counterweight consists of plastic or a corresponding two-hole tubular body. and a flat-shaped arm of the balance is threaded into the smaller oval hole, whereby the counterweight with its own weight is tightened on the arm of the balance.

, 58710 2

An application of the device according to the invention is shown in the accompanying figure. The arm 1 of the balance with its counterweights 2 is suspended by a flexible rope 3 in the feed chute 4, twisting the rope 3 through the folding points 5 and 6 on the arm 1 of the scale, and a weighing tube 7 is suspended at one end thereof.

When the weighing tube 7 is empty or partially filled, the situation is as shown in Fig. 1 and the shut-off flap 9 mounted at point 8 is open.

When the desired amount of feed has flowed into the weighing tube 7, the balance operates horizontally by turning it around the suspension point 5 to the position shown in Fig. 2. The second end 10 of the arm 1 of the balance then presses the other end 11 of the closing flap 9, closing the flap. When the feed in the weighing tube 7 is emptied into the feed tray by a separate remote control, the balance returns to the position of Fig. 1, the flap 3 opens and filling can start again. The weight of the filling is adjusted by the counterweight 2 of the scale, which is shown in more detail in Figure 3.

The counterweight 2 consists of a two-hole tubular body, of which the larger circular 12 has an actual counterweight, e.g. a steel bar 13 and a smaller hole 14 with an elliptical cross-section and dimensioned according to the balance arm 1, is threaded onto the balance arm 1, whereby the counterweight 2 is attached to the scale. 1 and is easily portable.
