Description

The invention of machines for cleaning and sorting grain, comprising a series of vertical air 1; canals arranged successively one after the other above the grain discharge screen and separated by vertical partitions into two halves, one of which serves to catch the loss of lice or impurity fractions.

In the proposed .ManjHHe, for the purpose of a more intrinsic separation of impurities and the separation of grain into fractions, the channel partitions are made in the form of one-sided rotary) sashes. In order to create a dimensionally wide canal of air flow, the receiving mouth of each air caiaaa is divided by partitions into a number of sleeves. In order to trap wild pests, a flare nanometer, a device in the form of a mesh movement of an endless belt installed in the grain was used: this is a cyclone and a reflective zero in the discharge sleeve of the cyclone.

The schematic drawing shows a longitudinal section of the proposed machine.

Mashia encloses several vertical air ducts 5, located successively one after another 1.ad cnycKinJM by an inclined sieve 15 Each droplet is divided by two vertical halves into two halves. The partitions are made in the form of pivotal reticular flaps 6, located one above the other. Lattice sash can be installed with various slopes to the vert ::; a.1; 1.

On the left side 7 of each, through the regaeto 15, an upward air flow is attached by means of a vellor tor. Air: each channel is fed by sleeve 2, to which: in the follower-whip; order, the left part of the 7 channels is attached at the mouth of the L. air intake, depending on its flow rate, with each individual

the channel is adjusted by the valves, and 3. The mouth of each channel, in order to create a cross section: the channel of a uniform air vent, is divided by partitions 4 into a number of sleeves. The right part of each canal: ala is used for suction and sedimentation of lost windage grain of lightweight grain or weeds.

All these channels, with their upper airflow to the cyclone 8 for trapping chaff and dust, have three vertical baffles 9 in it to clean the air coming out of the cyclone, which blows air, due to which the chaff and dust particles lose speed cyclone bottom. All settled in the cyclone. The mass is brought out by the screw 10.

At the end of the sieve U5, there is a channel 20 for the refined grain. The upper part of this channel is attached. Paragraph Inen cyclone 12.

The original m-atherzal is fed to the conveyors in the receiving bucket 13, where the screw 14 is spread across the sieve width 19. Large impurities are separated from the grain on this sieve, which converge into the screw 16 and go outside. The grain, passed through the grate 19, falls on the seeded pipette / 5, which makes longitudinal oscillations and scans: along this screen in the direction to the channel 20. Under the screen there is an L7 hopper and a chute to catch small weeds. From the bunker with the aid of a screw weeds are brought out. Sliding further along sieve 15, the grain gets successively under the jets of ascending air streams going through channels 5. The lightest impurities (dust, m kink , weed seeds, etc.). Impurities that are carried along by the jet: nalu upward have a different specific gravity and sail, are lifted to different heights and between the doors 6 are distilled into the second part of the channel, where they are deposited in the grooves 18, from where snoods are brought out; lighter impurities are diverted by a stream of air into the cyclone 8. On the second channel, a lightweight grain is removed from the grain-a. The third caval is intended to divide the refined grain into two grades. The air jet is stronger through this channel than in the first two channels. A second grade of grain rises along the channel and, entering the second part of the channel between the flaps 6, settles in the groove 18.

Grain of the first grade, moving further along sieve 15, falls into channel 20, where it rises up through the channel and blows into cyclone 12 with a strong jet of air.

In the upper part of the air jet path of the cyclone Hia, a mesh tape 2 / is mounted, which is installed vertically and has a bottom-up movement. All trapped grains (even with a grain of impurity, including a tick, if it AND | Meets in the grain, stick to the mesh tape and are drained into the chute 22,. The grain from the mesh is reflected and falls into the cyclone drain sleeve.

Channel 20 is made telescopic, so that the path of movement of the grain can be changed depending on these or other conditions.
