RU203037U1 - PNEUMATIC FEEDER WITH REGULATED FEEDING INTENSITY - Google Patents

Abstract

The proposed utility model is intended for dispensing granulated feed through a pipeline to a place of direct feeding with an adjustable intensity. the fact that the feed line is made in the form of telescopically connected pipes, and the pipe with the largest diameter is connected at one end with the lower part of the hopper, and at the other with a compressor. The device allows you to adjust the rate of delivery of feed without changing the pressure in the duct.

Description

The proposed utility model is designed for dispensing pelleted feed through a pipeline to the place of direct feeding with adjustable intensity.

Known device for distributing food to fish [1], consisting of a frame with a bunker installed on it, a bunker-dispenser. A damper is installed in the intermediate part of the transition between the hopper and the metering hopper. The metering hopper has a feed flap and a feed rate regulating flap. The unit is connected to a high pressure fan using a duct system.

The device does not have the ability to reduce the intensity of feed delivery without reducing the pressure in the air duct, which reduces the distance of transportation and delivery of feed.

Known feed dispensing device [2]. The pneumatic feed dispenser consists of a frame and a hopper mounted on it. The feed is supplied by a pneumatic spreader through a pipeline system. The spreader is powered by a continuous motor.

The dispenser drive and metering controller of the dispensed portions require electricity.

Known device for distributing food to fish [3], consisting of a frame with a bunker installed on it, a bunker-dispenser. A damper is installed in the intermediate part of the transition between the hopper and the metering hopper. The metering hopper has a feed flap. The unit is connected to a high pressure fan using a duct system.

The closest of the known analogs is a device for distributing food to fish [4], adopted as a prototype, consisting of a frame with a bunker installed on it, a direct drive blower with an autonomous power unit, and flap control levers. The feed is supplied by manual control of the feed flap and piping system.

The device does not have the ability to reduce the intensity of feed delivery without reducing the pressure in the air duct, which reduces the distance of transportation and delivery of feed.

The technical result of the proposed device for dispensing feed consists in the possibility of adjusting the intensity of dispensing feed without reducing the pressure in the duct.

The technical result is achieved by the fact that the feed line is made in the form of telescopically connected pipes, and the pipe with the largest diameter is connected at one end with the lower part of the hopper, and at the other with a compressor.

FIG. 1 shows a general view of the device.

The device consists of a frame 1, with a bunker 2 installed on it, into which feed 3 is poured. The feed line 5 is connected to the bunker 2 by means of a branch pipe 4 that does not have a damper. A pipe of a smaller diameter 6 is inserted into the feed line 5. The pipe connection is hermetically sealed, but it allows you to change the size A (see Fig. 1), that is, to move the pipe of a smaller diameter 6 inside the feed line 5. A compressor 7 is connected to the upper part of the feed line 5.

The device works as follows. The hopper 2 is filled with feed, which fills part of the internal volume of the feed duct 5 (see Fig. 1). A pipe with a smaller diameter 6 extends outward from the feed line 5 (dimension A is reduced, see Fig. 1). Further, the compressor 7 is turned on. The air flow passes through the annular gap between the feed pipe 5 and the pipe of a smaller diameter 6 and sharply changes directions and rushes through the pipe of a smaller diameter 6. Further, the pipe of a smaller diameter 6 is pushed into the feed pipe 5 (size A increases). At a certain position of the pipe of smaller diameter 6, the feed located in the lower part of the feed line 5 begins to be captured by the vortex air flow and is transported through the pipe of smaller diameter 6 to the point of delivery. At the same time, the intensity of dispensing is minimal. If it is necessary to increase the intensity of feed delivery, a pipe of a smaller diameter 6 is pushed into the feed line 5 (size A increases).
