Недостатки такого триера — низкая производительность и некачественное разделение исходной смеси сырья.The disadvantages of this trier are low productivity and poor separation of the initial mixture of raw materials.

Наиболее близким к предлагаемому по 15 технической сущности и достигаемому результату является триер, включающий барабан, выполненный из отдельных планок, щеточный отражатель, приспособление для загрузки, приемники готовой продукции и привод [2]. ²⁰ Closest to the proposed technical essence and the achieved result is a trier, including a drum made of individual strips, a brush reflector, a loading device, receivers of the finished product and a drive [2]. ²⁰

Недостатками этого триера являются низкая производительность, сложность конструкции и большая трудоемкость наладки и обслуживания.The disadvantages of this Trier are low productivity, design complexity and the great complexity of commissioning and maintenance.

Цель изобретения — повышение производительности триера за счет увеличения скорости вращения барабана.The purpose of the invention is to increase the performance of the trie by increasing the speed of rotation of the drum.

Поставленная цель достигается тем, что в триере, включающем барабан, выполненный из отдельных планок, щеточный отражатель, приспособление для загрузки, приемники готовой продукции и привод, планки выполнены с пазами, причем пазы смежных планок размещены с образованием ячеек, а привод расположен на внешней поверхности барабана.This goal is achieved by the fact that in the trier, which includes a drum made of separate planks, a brush reflector, a loading device, finished product receivers and a drive, the planks are grooved, the grooves of adjacent planks being placed to form cells, and the drive is located on the outer surface drum.

Кроме того, привод выполнен в виде зубчатого колеса.In addition, the drive is made in the form of a gear wheel.

На фиг. 1 представлен триер, продольный разрез; на фиг. 2 — разрез А—А на фиг. 1; на фиг. 3 — привод и зона выгрузки коротких частиц; на фиг. 4 — вид на ячеистую поверхность барабана.In FIG. 1 shows a trier, a longitudinal section; in FIG. 2 — section A — A in FIG. 1; in FIG. 3 - drive and discharge zone of short particles; in FIG. 4 is a view of the cellular surface of the drum.

Триер содержит барабан 1, выполненный из отдельных планок 2, установленных своими концами в боковые кольца 3, имеющие кольцевые пазы 4, опорные ролики 5, щеточный отражатель 6, привод, выполненный в виде зубчатого колеса 7. Планки 2 имеют пазы 8, причем при совмещении планок пазы 8 образуют ячейки 9. Планки 2 уста новлены в пазы 4 колец 3 вплотную друг к другу и только в зоне выгрузки коротких частиц имеется щель 10, образованная сопряжением зубчатого колеса 7 и планок 2.The trier contains a drum 1 made of separate strips 2, installed at their ends in the side rings 3, having annular grooves 4, support rollers 5, a brush reflector 6, a drive made in the form of a gear 7. The strips 2 have grooves 8, and when combined of the slots, the grooves 8 form the cells 9. The slats 2 are mounted in the slots 4 of the rings 3 close to each other and only in the discharge zone of short particles is there a gap 10 formed by pairing the gear 7 and the slats 2.

Электродвигатель, приспособление для загрузки и приемники готовой продукции на чертеже условно не показаны.An electric motor, a loading device and receivers of finished products are not conventionally shown in the drawing.

Триер работает следующим образом.Trier works as follows.

При включении электродвигателя зубчатое колесо 7, находясь в зацеплении с планками 2, начинает вращать барабан триера. Исходная смесь из загрузочного устройства подается на ячеистую поверхность в нижнюю часть барабана 1, образованную плотным взаимным прилеганием планок 2, увлекается к щеточному отражателю 6, который сметает с ячеистой поверхности барйбана 1 выступающие из ячейки длинные частицы и излишйюю, не попавшую в ячейки смесь. Длинные, частицы накапливаются в основании барабана и сходят с его торцов в приемники для длинных частиц. Короткие частицы, заполнившие ячейки 9, пройдя щеточный отражатель, покидают барабан через щель 10 между планками 2 в зоне выгрузки коротких частиц за счет центробежной силы, действующей на частицы. Барабан 1 опирается на опорные ролики 5, которые, легко вращаясь, позволяют неограниченно увеличить скорость вращения барабана 1 триера.When you turn on the electric motor, the gear 7, being in mesh with the straps 2, begins to rotate the drum of the triera. The initial mixture from the loading device is fed to the cellular surface in the lower part of the drum 1, formed by the tight mutual fit of the straps 2, is carried away to the brush reflector 6, which sweeps long particles protruding from the cell from the mesh surface of the drum 1 and the excess mixture that does not get into the cells. Long, particles accumulate at the base of the drum and descend from its ends to receivers for long particles. Short particles that fill the cells 9, passing the brush reflector, leave the drum through the slot 10 between the strips 2 in the discharge zone of short particles due to the centrifugal force acting on the particles. The drum 1 rests on the support rollers 5, which, easily rotating, allow you to unlimitedly increase the speed of rotation of the drum 1 triera.

Такая конструкция предлагаемого триера позволяет значительно повысить производительность за счет увеличения скорости 5 вращения барабана триера.This design of the proposed triera can significantly increase productivity by increasing the speed 5 of the rotation of the drum triera.

Claims

(54) TRIER The invention relates to a technique for separating a raw material mixture into fractions according to geometry, in particular, cleaning grain from impurities, and can be used in agriculture, seed production and other folk products. The known Trier, containing a cylindrical drum with an inner cellular surface, a brush reflector, adapting the loading and unloading of the processed raw material and the drive 1. The disadvantages of such a Trier are low productivity and poor quality separation of the initial mixture of raw materials. The closest to the proposed technical essence and the achieved result is the Trier, which includes a drum made of separate planks, a brush reflector, a device for loading, receivers of finished products and a drive 2. The disadvantages of this Trier are low productivity, complexity of design and greater complexity of setup. and service. The purpose of the invention is to increase the performance of the trimer by increasing the speed of rotation of the drum. The goal is achieved by the fact that in the trier, which includes a drum made of separate slats, a comic reflector, a device for loading, receivers of finished products and a drive, the slats are grooved, the slots of adjacent slats are placed with the formation of cells, and the drive is located on the outer surface the drum. In addition, the drive is made in the form of a gear. FIG. 1 shows the Trier, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - drive and discharge zone for short particles; in fig. 4 - view of the cellular surface of the drum. Trier contains drum 1, made of separate planks 2, installed with their ends in side rings 3, having annular grooves 4, support rollers 5, brush reflector 6, drive made in the form of a gear wheel 7. Planks 2 have grooves 8, and when combined the slats 8 form slots 9. The slats 2 are installed in the slots 4 of the rings 3 closely to each other and only in the discharge zone of short particles there is a slit 10 formed by the coupling of the gear wheel 7 and the slats 2. Electric motor, device for loading and receivers of finished products on h Conditionally not shown. Trier works as follows. When the electric motor is turned on, the gear wheel 7, which is in engagement with the strips 2, begins to rotate the triemer drum. The initial mixture from the loading device is fed to the cellular surface in the lower part of the drum 1, which is formed by tight intersection of the strips 2, is carried to the brush reflector 6, which sweeps long particles protruding from the cell surface of the drum 1 and is missing from the cell. The long, particles accumulate at the base of the drum and descend from its ends to receivers for long particles. Short particles filling the cells 9, pass the brush reflector, leave the drum through the slit 10 between the strips 2 in the zone of unloading short particles due to the centrifugal force acting on the particles. The drum 1 rests on the support rollers 5, which, when easily rotated, allow an unlimited increase in the rotational speed of the drum 1 of the Trier. Such a design of the proposed Trier allows to significantly IMPROVE productivity by increasing the speed of rotation of the Trier drum. Claims of the invention I.
