Device for separation of grain and seeds by length

FIELD: agriculture.

SUBSTANCE: device consists of at least three grain-cleaning modules installed successively one after another with a possibility of increasing their number each having an independent drive, grain-cleaning machine, pick-and-place device, frame composed of four vertical posts connected below by crossbeams one of which is removable and a receiving diverter for factions. The first grain-cleaning module also has a loading device and the last one has a shipping device. The size of cells of each following grain-cleaning machine in relation to the previous one decreases at an equal value starting from the first one to the last one and their horizontal axes are away from each other by height at an equal value: Nt.> Lt. tg γ, where γ is a natural angle of slope, Lt. is a distance between grain-cleaning modules. The support parts of each post except for the last grain-cleaning module, which is secured firmly on its stand, have rollers and holders for firm mounting of the post in a new position and increasing the number of grain-cleaning modules at the same time. The tanker of the loading device can move horizontally for which purpose it has rolling-contact bearings and holders. The vertical posts of the module frames are telescopic capable of changing height due to the fact that the ends of their posts are made as round rods with teeth on the side facing the frame centre to couple with the worm gear teeth and installed on hinges on top of the telescopic part of the two vertical post opposite diagonally. All grain-cleaning modules are installed so that their rotation speed can be changed.

EFFECT: improved quality of cleaning due to a prompt setup of the device by installing an additional grain-cleaning module.

The invention relates to agriculture and can be used to create devices screening of grains and seeds in length.

Known Trier as a separate work body for grading of seeds and grains along the length described in the book Vimalananda and Everbach "Agricultural machinery", M, "Colossus", 2004, str. It consists of a cylinder with cells on the inner surface and the tray installed inside, and the screw for removal of small seeds or grains caught in the tray to the result of the division.

A device with multiple treename the patent RU NO. 2275242 WV 1/02, which consists of several treerow installed at each other, but a significant disadvantage of this device is poor cleaning and the inability to sort multiple sizes of seeds and quick changeover from one type to another.

The problem is solved due to the fact that the device for screening grain and seed length is at least three consecutive installed indent modules with the possibility of increasing their number, with - each - Autonomous drive, Trier, overload device, a frame comprising four vertical posts connected bottom crossbars, one of which is made removable and receiving retractor DL the fractions, with the first indent module also has a boot device, and the last shipment of the device, the cell size of each subsequent Trier relative to previous decreases by the same amount, from the first to the last, and the horizontal axis are separated from each other in height by the same amount: NT.>L. tgγ, where γ is the angle of repose of the grain, L. - the indent distance between the modules and the supporting part of each column, except the last indent of the module, which is fixed at its base with rollers and clamps for rigid fastening of racks in the new position when the number of indent modules, bunker boot device is made with the possibility of lateral movement, which is provided with supports the rolling elements and the retainer, while the upright frames of the modules in the lower part is made telescopic with the ability to change their height by performing all of the racks in the form of round bars with teeth on the side facing the center of the frame for coupling with the teeth of the worm wheel, set the hinge at the top of the telescopic parts of the two opposite diagonal uprights, all screening is installed with the possibility of changing the speed of their rotation.

Consider the device are chains. It consists of several (3 or more) consecutive installed indent modules 1 with the possibility of increasing their number, each having Autonomous drive 2, Trier 3, the boot 4 and the loading device 5, a frame 6 of the four vertical posts 7, connected at the bottom by cross members 8, one of which is made removable 9, otodama-receiving device 10 for fractions. The size of cells in each subsequent Trier relative to previous decreases by the same amount, starting with the first 11 (reception) to the last 12, and the horizontal axis are separated from each other in height by the same amount - HT.≥L.tgγ where L. - the distance between the indent modules horizontally, γ - angle of repose sort of grain.

The boot of the bucket Elevator 13, 14 reloading and discharge conveyors 15 are made with the possibility of changing their length by performing the Central part of the Central Committee., telescopic and is equal to the CC.=4-5 KV, where K=1,618, the width of the duct 16 of the bucket 13 or conveyor 14 is 15. The supporting part 17 of each rack 7, except for the last indent of the module 12, which is fixed at its base 18 provided with rollers 19 and the retainer 20. The hopper 21 of the boot device 22 is made with the possibility of horizontal movement and for this purpose is provided with supports roller 19 and the retainer 20. Vertical posts 7 frames 6 modules 1 in the lower part is made telescopic with the ability to change their height by performing the ends of the uprights 7 in the form of round rods 23 with the teeth 24 on the side facing the center of the frame 6, and mating with the teeth of the worm wheel 25 mounted pivotally at the top of the telescopic part 26 of the two opposite diagonal uprights 7. Autonomous drive 2 Trier 3 of each module 1 can be performed by using a belt, gear or friction gear with the possibility of changing the speed of rotation of treerow 3. Strokes 27 shows installable module 1.

Consider the workflow indent chain. Grain or seeds come first in a hopper 21 boot device 22, and the bucket Elevator 13 is fed in the first indent module 11, which selects from the received mass short impurities, which are allocated by the device 10, and the remaining mass by gravity through the loading device 14 is transmitted to the next Trier and so successively until the last three are gathered together the module 12, and then sorted the weight of grain is sent to storage.

The indent number of modules 1 can be calculated, and if necessary, install additional indent module thanks to the supports rolling those modules that are to newly installed, rolling it back and lift up through the worm gear (teeth 24 and the worm wheel 25) on the telescopic parts of the uprights 7, then install the indent module at a specified distance so as to conform to the condition HT.≥L.tgγ. The rise of treerow carried out by any known worm gearbox. Then by telescopically change the length of the boot of the bucket Elevator 13, transshipment 14 and outlet 15 of the conveyors.

This conversion circuit of treerow ends.

One additional technical result of the invention is that the invention allows to obtain an intermediate fraction of seed or grain size characteristics within a given interval of screening, as well as in mixture can be the seeds and grains with useful properties within a given range of screening, for example, if the mixture consists of oats and barley including, and even the presence of other seeds with other features, allows you to select them separately, which is impossible to achieve using other technical is rest.
