The invention relates to agriculture and can be used for cleaning and grading of seeds and grain length to thermocontroller points.

A known method of cleaning and screening or in General tienovania described in the book Vimalananda and Vierbuchen "Agricultural machinery", M. Colossus, 2004, str., namely, that the seed or grain is passed through Trier - rotating cylinder with cells on the inner surface and the tray with screw inside, and at the outlet of Trier receive two streams differing in length, one - similarity, which is longer than the cell, and the second thread is all that could fit in a cell and hit the tray and millet displayed outside.

A significant drawback of this method is the low quality of cleaning and screening, as to obtain a desired size of the seed or grain is necessary several times to skip through Trier. Another disadvantage - low productivity and low maintainability.

The purpose of the invention is to improve the treatment quality and performance, and maintainability of the mechanism.

For the implementation of the tasks is proposed a method of triebovaniia where tienovania provide a device for screening grain or seed length, which represents the indent sections, each of which is equipped with privado is, frame with vertical supports and Trier with cells, and the cell size Trier of each subsequent section differs from the previous one by the same amount in the order of increasing from minimum to maximum, vertical supports each section is made telescopic, and their grounds with rolling bearings and retainers, the hopper also performed with the supports of the rolling elements and the retainer, the device is equipped with a boot Noria and handling conveyors, body parts are in the middle of their length are connected by telescopic joints, parallel to each indent sections have additional screening with the same cell size as the primary Trier, each Trier the inside section has a hinge with adjustable angle of inclination to the longitudinal axis, while tzerovani first load the sorted material in the first section where they separate the grain or seeds of the appropriate size, after which the grain or seeds, proceed to the next section and so on until the last.

Significant new features:

- first make the indent section, consisting of the drive frame with vertical supports and the Trier

- then install these sections so that screening with cells of various sizes were on the same horizontal axis and which follow each other is the order of increasing cell size, differing by the same amount, starting from the minimum to the maximum possible size of the diameter of the cell

- the drive is performed in the shape of a belt, a gear, friction and other programs with the possibility of adjusting the position of each of Trier in height and on the horizon, for which the vertical supports of each section perform telescopic and grounds comply with rolling bearings and retainer,

- the hopper perform on supports rolling with the possibility of movement in a horizontal plane and lock,

- boot Noria and handling conveyors perform telescopic connection of body parts in the middle of their length,

- each indent section do with the ability to complement parallel treename on the sides the same size as the one already installed;

- telescopic parts of the supports are sections provide electromagnetic clamps and the inner part of the support - rod - supply serrated surface along the vertical axis along the side and interconnected with it the worm, pivotally mounted in the walls of the outer part of the telescopic support;

- the number of sections of the COP determined as: Kc=(lmax-lmin)/Δli, where lmax is the maximum length of the seed in the sample, lmin is the smallest length of the seed in the sample, Δli - interval changes the length of the seed equal to 1 mm or 0.5 mm;

every Trier inside of saccountable hinge with adjustable angle of inclination to the longitudinal axis.

These new significant features in conjunction with the known necessary and sufficient to achieve a technical result, in all cases, to which the requested amount of legal protection.

Technical result: improved productivity, quality cleaning and screening, improving the maintainability is achieved due to the fact that

- first make the indent section, consisting of the drive frame with vertical supports and Trier, and set them so that screening with cells of various sizes were on the same horizontal axis and which follow each other in order of increasing cell size, differing by the same amount, starting from the minimum to the maximum possible size of the diameter of the cells to flow sorted grain sequentially passed through all the sections and thereby increased productivity, maintainability, because in case of failure of one of Trier can be replaced by a new one;

- boot elevators and handling conveyors telescopic connection of body parts, as well as the implementation of struts sections and supply bearings rolling allows you to change the number of sections in the chain, if the need arises, and this is possible if processing samples from the seed lot or ze is to be found, for processing this batch of seeds need three partitions, and installed, for example, four or, on the contrary, you want more partitions than there, i.e. there is a new feature - the ability to reconfigure the supply chain and thereby increase the technological capabilities triebovaniia.

An example of the method of triebovaniia. If the received batch of seed or grain, that must be done first indent section, consisting of the drive frame with vertical supports and Trier, and then install them so that screening with cells of various sizes were on the same horizontal axis and to follow each other in order of increasing cell size, differing by the same amount, starting from the minimum to the maximum possible size of the diameter of the cells, the actuator are in the form of a belt, a gear, friction and other programs with the possibility of adjusting the position of each of Trier in height and on the horizon, for which vertical supports each section perform telescopic, and their grounds do with rolling bearings and retainer, hopper performs on supports rolling with the possibility of movement in a horizontal plane and clamp, boot Noria and handling conveyors perform telescopic connection of body parts in the middle of their length, etc is what every indent section can be supplemented with parallel treename on the sides are the same size as already established, while the telescopic parts of the supports are sections provide elektromagnitnykh clamps and the inner part of the support - rod - supply serrated surface along the vertical axis along the side and interconnected with it the worm, pivotally mounted in the walls of the outer part of the telescopic leg, and the number of sections of the COP determined as: Kc=(lmax-lmin)/Δli, where lmax is the maximum length of the seed in the sample, lmin is the smallest length of the seed in the sample, Δli - interval changes the length of the seed, 1 mm or 0.5 mm, and each Trier inside section has articulated with adjustable angle to the longitudinal axis.

How triebovaniia, characterized in that tienovania provide a device for screening grain or seed length, which represents the indent sections, each of which is supplied by the drive frame with vertical supports and Trier with cells, and the cell size Trier of each subsequent section differs from the previous one by the same amount in the order of increasing from minimum to maximum, vertical supports each section is made telescopic, and their grounds with rolling bearings and retainers, the hopper also performed with the supports of the rolling elements and the retainer, the device is equipped with a boot Noria and handling conveyors, hull de is Ali are in the middle of their length are connected by a telescopic connection, in parallel, each indent sections have additional screening with the same cell size as the primary Trier, Trier each inside section has a hinge with adjustable angle of inclination to the longitudinal axis, while tzerovani first load the sorted material in the first section where they separate the grain or seeds of the appropriate size, after which the grain or seeds, proceed to the next section and so on until the last.
