Description

Изобретение относится к отвально-транспортирующим машинам, а именно к роторным метателям и может быть использовано в горнодобывающей, строительной и других отраслях промышленности.The invention relates to dumping and transporting machines, namely to rotary throwers and can be used in mining, construction and other industries.

Известен метатель грунта, включающий 5 установленный на раме барабан с лопастями для подачи материала в ковш скрепера из зоны его подрезающего ножа [1].Known soil thrower, including 5 mounted on the frame of the drum with blades for feeding material into the scraper bucket from the area of its cutting knife [1].

Расстояние, на которое перемещается материал, очень незначительно и составляет 2—Зм. ⁰ The distance over which the material moves is very small and amounts to 2 — 3m. ⁰

Наиболее близким к изобретению техническим решением является метатель грунта, включающий ротор с выбросными лопатками и соосно расположенный с ним кожух, имеющий зону загрузки и зону выброса грун- 15 та, расположенные по наружному контуру кожуха [2].The technical solution closest to the invention is a soil thrower, comprising a rotor with exhaust blades and a casing coaxially located with it, having a loading zone and a soil discharge zone 15 located along the outer contour of the casing [2].

Известная конструкция метателя не может обеспечить большую дальность метания материала из-за того, что зона . загрузки расположена на периферии рабочего колеса с лопатками по его наружному контуру. При такой конструкции в случае увеличения числа оборотов рабочего колеса для получения большой окружной скорости, ве2 личина которой и обуславливает большую дальность метания, резко возрастают момент сопротивления и ударные нагрузки на лопатки в момент забора материала.The known design of the thrower cannot provide a large throwing range of material due to the fact that the zone. loading is located on the periphery of the impeller with blades along its outer contour. With this design, in the case of an increase in the number of revolutions of the impeller to obtain a high peripheral speed, the value of which determines a large throwing distance, the moment of resistance and shock loads on the blades sharply increase at the moment of material intake.

Цель изобретения — увеличение дальности метания материала путем увеличения окружной скорости вращения ротора.The purpose of the invention is to increase the throwing range of the material by increasing the peripheral speed of rotation of the rotor.

Лопастной метатель работает следующим образом.Blade thrower works as follows.

Посредством питателя 16 горная масса подается в приемный желоб 7, по которому она через загрузочное окно 6 поступает в поворотный секторный желоб 5, скользя ₃₀по его днищу, образованному колосниками 8, к выходу из него. Горная масса, во время своего движения по колосникам 8, под воздействием силы тяжести, разгоняется дополнительно гребнями 9 верхних кромок выбросных лопастей 3, которые, пере- 35 мещаясь между консольными колосниками 8, проталкивают нижний слой потока горной массы в направлении вращения ротора 1, кинематически связанного с приводом 17. При выходе из секторного желоба поток ₄₀горной массы приобретает скорость верхних кромок 9 лопастей 3. При дальнейшем движении частиц горной массы они ускоряются под действием центробежной силы и перемешиваются по изогнутой поверхности лопасти 3, ограниченной с боков кожухом, 45 к ее нижней периферийной кромке. Конструкция метателя рассчитана таким образом, что при срыве потока горной массы с нижней кромки лопасти 3 во время вращения ротора 1, происходит ее метание под угломBy means of the feeder 16, the rock mass is fed into a receiving chute 7, through which it enters through a loading window 6 into a rotary sector chute 5, sliding ₃₀ along its bottom, formed by grates 8, to the exit from it. The rock mass, during its movement along the grates 8, under the influence of gravity, is further accelerated by ridges 9 of the upper edges of the exhaust blades 3, which, moving 35 between the cantilever grates 8, push the lower layer of rock mass in the direction of rotation of the rotor 1, kinematically associated with the drive 17. When leaving the sector trench, the rock mass ₄₀ acquires the speed of the upper edges of the 9 blades 3. With further movement of the rock particles, they are accelerated by centrifugal force and are mixed along the curved surface of the blade 3, limited by the casing on the sides, 45 to its lower peripheral edge. The design of the thrower is designed in such a way that when the rock mass flows from the lower edge of the blade 3 during rotation of the rotor 1, it is thrown at an angle

45° к горизонту. При изменении дальности метания изменяют скорость вращения ротора 1 и положение секторного желоба 5 вокруг оси ротора 2, фиксируя сектор 5 болтами 10. В этом случае метание горной массы происходит под углом больше или меньше 45°.45 ° to the horizon. When changing the throwing range, the rotational speed of the rotor 1 and the position of the sector groove 5 around the axis of the rotor 2 are changed, fixing the sector 5 with bolts 10. In this case, the rock mass is thrown at an angle greater than or less than 45 °.

Ротор 1 установлен на стойках И на поворотной раме 12, посредством которой производится изменение направления метания в горизонтальной плоскости. От случайных просыпей горной массы в радиальном направлении (кроме направления метания) оборудование и обслуживающий персонал защищается предохранительным козырьком 14 и поддоном 15 для сбора случайной просыпи.The rotor 1 is mounted on racks And on a rotary frame 12, through which the direction of throwing is changed in the horizontal plane. From accidental spills of rock mass in the radial direction (except for the direction of throwing), equipment and maintenance personnel are protected by a safety visor 14 and a pallet 15 to collect accidental spills.

Применение изобретения обеспечивает возможность безударного разгона материала поступающего в центральную часть ротора и метаемого с его периферийной части, до больших скоростей, за счет чего и увеличивается дальность метания. Кроме того, безударный вход горной массы в приемную часть ротора (секторный желоб) и плавное ее прохождение по изогнутой выбросной лопасти позволяет метать крупнокусковую скальную породу непрерывным потоком.The application of the invention provides the possibility of shockless acceleration of the material entering the Central part of the rotor and tossed from its peripheral part to high speeds, due to which the throwing range is increased. In addition, the unshocked entrance of the rock mass into the receiving part of the rotor (sector trough) and its smooth passage through the curved ejection blade allows the lumpy rock to be thrown in a continuous stream.

Claims

The invention relates to waste transporting machines, namely rotary throwers and can be used in the mining, construction and other industries. A soil thrower is known, which includes a drum mounted on a frame with blades for feeding material into the scraper carriage from the area of its undercutting knife 1. The distance that the material moves is very small and is 2–3 m. soil thrower, which includes a rotor with discharge vanes and a casing coaxially located with it, having a loading zone and a soil ejection zone located along the outer contour of the casing 2. The known thrower construction cannot provide a large yes Flax metania material due to the fact that the zone. loading is located on the periphery of the impeller with blades along its outer contour. With such a design, in the event of an increase in the number of revolutions of the impeller to obtain a high peripheral speed, the magnitude of which causes a large throwing range, the moment of resistance and the shock loads on the blades at the moment of material intake increase sharply. The purpose of the invention is to increase the range of material sweeping by increasing the peripheral speed of rotation of the rotor. The goal is achieved by the fact that in a paddle tiller, including a rotor with discharge vanes, coaxially arranged with it a fixed casing with a material loading unit and a drive, the central part of the casing has a side loading window in which the loading unit is installed, made in the form of a sector trough rotation around the axis of the rotor, while the bottom of the gutter is formed by concave cantilevered grates, and the discharge vanes on their edges in the central part of the rotor have ridges that are arranged with the possibility of passage between cantilevered grate when the rotor rotates. FIG. I shows the thrower, front view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3. The proposed blade thrower contains a rotor 1, with an axis of rotation 2 with discharge curved blades 3, enclosed in a fixed casing 4 in the form of side cheeks, with a loading unit in the central part in the form of a pie trough 5 with a loading window 6 and receiving chute 7. The bottom of the sector gutter 5 is formed by concave cantilevered grate 8. The edges of the outboard blades 3, located near the central part of the rotor 1, are made in the form of ridges 9 located between the concave grate 8. Sector chute 5 has the ability to turn around rotor 2 when setting range propelling Later Click, to her fixation screws 10 after adjustment. The axis of the rotor 2 is mounted on racks 11 mounted on a pivoting frame 12 equipped with a chassis 13. The upper part of the rotor 1 is closed by a safety hood 14, and under the lower part of the rotor 1 is installed a pallet 15 for collecting spills. The material for throwing is fed into the receiving chute 7 by means of a separate feeder 16. The rotor 1 of the paddle thrower is rotated by the drive 17. The paddle thrower works in the following way. Through the hearth feeder 16, the mass is fed into the receiving chute 7, through which it enters through the loading window 6 into the rotary sector chute 5, along its bottom, which is formed by the grate 8, to exit from it. The mountain mass, during its movement through the grates 8, under the influence of gravity, accelerates with additional ridges 9 upper edges of the outflow vanes 3, which, moving between the cantilevered grates 8, push the lower layer of the rock mass flow in the direction of the rotor rotation 1, kinematically associated with the drive 17. When leaving the sector trough, the flow of rock mass acquires the speed of the upper edges of 9 blades 3. With further movement of the particles of the rock mass, they are accelerated by centrifugal force and move a curved blade surface 3 bounded laterally casing to its lower peripheral edge. The design of the thrower is designed in such a way that when the flow of rock mass is disrupted from the lower edge of the blade 3 during rotation of the rotor 1, it is thrown at an angle of 45 ° to the horizon. When the throwing distance is changed, the speed of rotation of the rotor 1 and the position of the sector chute 5 around the axis of the rotor 2 are changed, fixing the sector 5 with bolts 10. In this case, the rolling of the rock mass occurs at an angle greater or less than 45 °. The rotor 1 is mounted on pillars 11 on the pivoting frame 12, by means of which the direction of the throwing is changed in the horizontal plane. The equipment and the maintenance personnel are protected from accidental requests from the mountain mass in the radial direction (except for the direction of throwing) equipment. The personnel are protected by a protective cover 14 and a pallet 15 for collecting accidental spills. The application of the invention provides the possibility of shock-free acceleration of the material entering the central part of the rotor and swept from its peripheral part to high speeds, due to which the range of the throwing is increased. In addition, the shock-free entrance of the mountain mass into the prim. Small part of the rotor (sector trough) and its smooth passage through the curved outward blade allows one to sweep the large-scale rock in a continuous flow.
