Description

The invention relates to the technology of transportation and relates to pneumatic transport devices for batch transportation to technological machines piece goods or granular material.

The purpose of the invention is the expansion of the technological capabilities of the device by providing automatic batching and transportation of piece goods or granulated substances.

FIG. 1 shows a diagram of the proposed device, front view; in fig. 2 - the same, a fragment of the issuance of a portion of products in the pipeline, in FIG. 3 - section A — A in FIG. one; in fig. 4 - section B — B in FIG. 2

The device contains a hopper 2 for items 1, a transport pipeline 3 with an intake opening 4, a metering chamber 5 with a mesh bottom 6 and a channel 7 for supplying compressed air from the highway 8, an actuator 9. The metering chamber 5 is made in the form of a glass with an outer face 10 on its upper end, and the glass is installed in the bottom of the hopper 2 on the same axis BB with the intake port of the transport pipeline with the possibility of reciprocating movement

along its axis GG by means of the actuator 9 and contacting its upper end with the intake port 4, having an annular seal 11, the transport pipe _{5 of the} wire at the time of delivery of the portion of products (Fig. 3).

The device works as follows. Pieces (or granular material) is loaded into hopper 2. When the motor is turned on, it starts

⁰ rotate the cylindrical cam 12, transmitting through the lever 13 reciprocating motion to the glass. At that moment, when the glass 5 is in its lowest position (Fig. 1), the products fill 15 the glass, then during its upward movement due to shaking, all extra products spontaneously pour into the bunker (outer chamfer 10 at the end of the glass 5 does not allow the products to linger at the end), glass 5 enters the intake

20 4 pipe and sealed by sealing 11. At this point, the channel 7 of the glass is combined with the main channel 8, and the compressed air through the grid 6 enters the product and pushes them into

25 pipe 3. After that, the glass 5 is moved to the lowest position and the cycle repeats.
