RU180557U1 - Reception and distribution device of a grain cleaning machine - Google Patents

Abstract

The utility model relates to receiving and distributing devices of grain cleaning machines and units and can be used in other sectors of the economy engaged in sorting bulk material. The receiving and distributing device of the grain cleaning machine contains a grain distributor in the form of an inlet pipe with a conical flow distributor and four pipes installed above the metering hopper with a feed slot. EFFECT: increased uniformity of input of bulk material across the width of the air separation channel of a grain cleaning machine. 1 silt

Description

The utility model relates to agricultural engineering, in particular to the reception and distribution devices of grain cleaning machines and assemblies, and can be applied in other sectors of the economy engaged in the sorting of bulk materials.

Known devices for the distribution of bulk materials containing a grain distributor in the form of a distribution screw connected to a loading grain line, and a pressure valve for regulating the thickness of the material to be distributed. The valve opens under the pressure generated by the screw, which is transmitted through a grain pile (Volosevich NP, Druzhkin AV Machines for post-harvest grain processing. - Saratov, 1993, p. 45).

The main disadvantage of the known devices is the uneven distribution when changing the performance of the machine.

A device for separating the flow of bulk material, comprising a grain distributor in the form of an inlet pipe with a flow divider and two symmetric diverging output pipes. The flow divider is rotated by applying a signal from the pressure sensors to the pushers. Each outlet pipe has an additional grain distributor and their subsequent number doubles depending on the width of the air separation channel, (description of patent No. 148656, IPC IPC B07B 11/06 (2006.01), published on December 10, 2014).

The known device does not provide an even distribution of bulk material due to the large number of stages of flow separation.

The technical result from the use of the claimed utility model is to increase the uniformity of the distribution of grain heaps over the width of the separating channel.

The technical result is achieved by the fact that in the receiving and distributing device of the grain cleaning machine, including a loading pipe, a grain flow divider and outlet flexible pipes. The flow divider is made in the form of a cone located in the center of the cylindrical body, the bottom of which is provided with holes made with the possibility of fixing the outlet flexible pipes in them.

The drawing shows the receiving and distributing device of a grain cleaning machine.

The device consists of a grain distributor, including an inlet 1 pipe and a conical flow distributor 2, a distributor housing 3, pipes 4,5,6,7 which are located at the base of the conical distributor. The outlets of the nozzles are arranged in a row above the hopper with the dispenser 8. Through the metering flap 9, the bulk material is fed into the air separation channel.

The receiving and distributing device of a grain cleaning machine operates as follows.

The flow of bulk material is fed into the inlet pipe 1, enters the cone distributor 2, at the exit from which a cylindrical stream is formed, which is sent to the outlet pipes 4, 5, 6, 7. The outlet pipes direct the material flow to the hopper 8. Through the metering flap the material is fed into the air separation channel. In this way, a batch feed of material for cleaning is eliminated.

Claims (1)

Reception and distribution device of a grain cleaning machine, including a loading nozzle, a grain flow divider and outlet flexible nozzles, characterized in that the flow divider is made in the form of a cone located in the center of a cylindrical body, the bottom of which is provided with holes made with the possibility of fixing the outlet flexible nozzles in them .
