(54) УСТРОЙСТВО ДЛЯ ДОЗИРОВАНИЯ КОРМОВ(54) DEVICE FOR FEEDING FOOD

II

Изобретение относитс к сельскохоз йственному машиностроению, в частности к устройствам дл дозировани кормов.FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, feed metering devices.

Известно устройство дл дозировани кормов, содержащее задатчик, бункер-дозатор с приводом от электродвигател , двум емкост ми с балансирами , пружинами и зубчатыми передачами , и мостовую измерительную схему l.A device for metering feed is known, which contains a setting unit, a metering hopper driven by an electric motor, two tanks with balancers, springs and gears, and a bridge measuring circuit l.

Недостатком такого устройства вл етс низка точность дозировани из-за колебани удельного веса молока , служащего эталоном дл взвешивани корма.The disadvantage of such a device is low dosage accuracy due to fluctuations in the specific gravity of milk, which serves as a benchmark for weighing the feed.

Цель изобретени - повышение точности дозировани корма.The purpose of the invention is to improve the accuracy of dosing feed.

Указанна цель достигаетс тем, что в устройство введена емкость с эталонной жидкостью, в нижней части которой установлен перепускной клапан, а также мерник с запорным клапаном в верхней части и след ща система положени мерника, при этом мерШ1КThis goal is achieved by the fact that a container with a reference liquid is inserted into the device, in the lower part of which a bypass valve is installed, as well as a measuring device with a shut-off valve in the upper part and a tracking system of the measuring device, and

расположен внутри емкости с эталонной жидкостью а перепускной и запорный клапаны св заны с задатчиком.It is located inside the vessel with the reference liquid and the bypass and shut-off valves are connected to the setpoint device.

На чертеже схематично изображено устройство дл дозировани корма.The figure schematically shows a device for dispensing feed.

Устройство содержит задатчик I, емкость 2 с эталонной жидкостью, в нижней части которой установлен перепускной клапан 3. Внутри емкости 2. расположен мерник 4 с запорным клапаном 5 в верхней части. Запорный 5 и перепускной 3 клапаны св заны с задатчиком 1. Устройство содержит, также след щую систему 6 положени мерника 4, котора управл ет положением мерника 4 в зависимости от сигнала задатЧика I, дл чего на мернике 4 имеетс зубчата передача 7.The device contains a setting device I, a container 2 with a reference liquid, in the lower part of which a bypass valve 3 is installed. Inside the container 2. there is a measuring device 4 with a shut-off valve 5 in the upper part. The shut-off 5 and bypass 3 valves are connected to the setting device 1. The device also contains a tracking system 6 of the position of the measuring device 4, which controls the position of the measuring device 4 depending on the signal of the setting I, for which there is a gear 7 on the measuring device 4.

Claims

The container 2 has drain holes 8 and 9, a container 10 with a balance bar 11, a spring I2 and a gear 13 connected to the slide potentiometer 14 of the bridge measuring circuit 15 is installed under the tank 2 with the reference liquid, the device contains a tank 16 with a balance bar 17, a spring 18 and a gear 19 connected to the engine of the potentiometer 20 of the bridge measuring circuit 15. The metering hopper 21 is driven by an electric motor 22 included in the diagonal of the bridge circuit 15. The device for dispensing feed works as follows anavlivaets predetermined dose of food. In proportion to a given dose (weight), the tracking system shifts the measuring device A by means of a gear transmission by the value L into a container 10 filled with a standard liquid with a specific weight of 1 g / cm. After the displacement of the measuring device 4, the signal of the setting device 1 triggers the valve 5 (for example, electric magnets) and closes the upper opening of the measuring device. The dip of the dipstick L determines the volume of the reference liquid or the weight of the reference liquid (taking into account its specific weight equal to 1 g / cm) Next, the valve 3 is triggered by a signal from the setting device 1, resulting in the discharge of the reference liquid through the opening 8. At In this case, the liquid column with the LI L from the closed valve 5 of the measuring device 4 does not galtete. When the position of the valve 3 changes and the valve 5 is simultaneously opened, the fluid is drained from the measuring device 4 to the container 10. Under the weight of the incoming liquid, the container 10 goes down and through the balance bar 11, the spring 12 and the gears 13 transfers the slider of the potentiometer 14 in the bridge circuit 15. 94 Circuit 15 is unbalanced, and electric current flows through motor 22. During operation of the engine 22, the dosing material from the dosing bin 21 enters the tank 16. The dosing of the dosing feed from the dosing bunker 21 to the tank 16 causes the displacement of the potentiometer 20 of the circuit 15 through the balance bar 17, spring 18 and gear gear 19. Once the weight of the dosing feed in the tank 16, it reaches the weight of the reference fluid in the tank 10, balance occurs in the bridge circuit 15, the current through the excitation winding of the electric motor 22 does not flow, and the feed from the metering hopper 21 is stopped. The application of the invention allows the dosing of feeds with high accuracy. Claims An apparatus for dispensing feed containing an actuator, an electric motor driven metering hopper, two tanks with balancers, springs and gears, and a pavement measuring circuit, characterized in that, in order to improve metering accuracy, it is equipped with a tank with a reference liquid the lower part of which is equipped with a bypass valve, a measuring device and a shut-off valve in the upper part and a tracking system of the position of the measuring device, the measuring device being located inside the container with the reference liquid, and the bypass valve shutoff valves associated with setpoint Sources of information received note in the examination 1.
