(54) БАШМАК КОВШОВОГО ЭЛЕВАТОРА(54) BASHMAK BUCKET ELEVATOR

Изобретение относитс к промышленному транспорту, а именно к баш.макам ковшовых элеваторов дл сыпучих грузов.The invention relates to industrial transport, in particular, to bucket elevators for bulk cargoes.

Известен башмак ковшового элеватора, содержащий корпус, днище которого закреплено на нем шарнирно, эксцентрик, кинематически св занный с валом концевого элемента , и т гу дл кинематической св зи эксцентрика с днищем (;A bucket elevator shoe is known, comprising a housing, the bottom of which is hinged on it, an eccentric connected kinematically to the shaft of the end member, and a rod for kinematically connecting an eccentric to the bottom (;;

Однако в этом башмаке дл псевдоожижени груза неподвижное днище колеблет- Ю с в вертикальных направл ющих, имеющих в абразивной среде малый срок службы и больщую веро тность заклинивани днища. Кроме того, отсутствие возможности регулировани амплитуды колебаний днища сужает технологические возможности элеватора .However, in this shoe for fluidizing the load, the stationary bottom oscillates in vertical guides, which have a short service life in the abrasive medium and a greater likelihood of the bottom becoming jammed. In addition, the inability to control the amplitude of oscillations of the bottom narrows the technological capabilities of the elevator.

Целью изобретени вл етс расширение технологических возможностей путем регулировани амплитуды колебаний днища и повышение надежности в работе.20The aim of the invention is the expansion of technological capabilities by adjusting the amplitude of the oscillations of the bottom and increasing the reliability in operation.

Эта цель достигаетс тем, что днище закреплено одним своим концом на корпусе посредством оси, параллельной валу концевого элемента, а на другом его конце вы2This goal is achieved by the fact that the bottom is fixed at one end on the housing by means of an axis parallel to the shaft of the end element, and at the other end thereof

полней р д отверстий дл шарнирного закреплени в них конца т ги.a full row of holes for hinging the end of the rod in them.

На фиг. 1 изображен башмак элеватора, общий вид; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the elevator shoe, general view; in fig. 2 shows section A-A in FIG. one.

На корпусе 1 башмака установлен загрузочный лоток 2. Внутри башмака смонтирован на валуЗ концевой элемент 4, который огибает т говйй орган 5 с ковшами 6. На валу 3 закреплено зубчатое колесо 7, наход щеес в посто нном зацеплении с шестерней 8, закрепленной на консольно установленной в подшипниках 9 оси 10. На свободном конце оси 10 закреплена эксцентрикова втулка (эксцентрик) И, котора с помощью подшипника 12 соединена с т гой 13. Т га 13 посредством пальца 14 соединена с подвижным полукруглым днищем 15 башмака элеватора. Палец 14 устанавливаетс в одном из р да отверстий 16 подвижного днища 15. Подвижное днище 15 с помощью оси 17, параллельной оси концевого элемента, закреплено на корпусе 1 башмака.On the case 1 of the shoe, a loading tray 2 is installed. Inside the shoe, an end element 4 is mounted on the shaft3, which bends around the traction body 5 with buckets 6. On the shaft 3 there is a gear wheel 7 fixed in constant engagement with the gear wheel 8 mounted on the console in bearings 9 of axis 10. At the free end of axis 10 an eccentric bushing (eccentric) I is fixed, which with the help of bearing 12 is connected to a thrust 13. Th 13 with a finger 14 connected to a movable semicircular bottom 15 of an elevator shoe. The finger 14 is mounted in one of a series of holes 16 of the movable bottom 15. The movable bottom 15 is fixed by means of an axis 17, parallel to the axis of the end member, on the body 1 of the shoe.

Claims

The movement from the endless traction unit 5 Q by buckets 6 is transmitted to the shaft 3, which rotates, transmits torque through the gear wheel 7 and the bristle 8 to the axis 10. The axis 10 rotates in the bearings 9 together with the eccentric 11, through the latter acts on tug 13, forcing it to perform oscillatory movements in a vertical plane. T ha 13 through the finger 14 interacts with the movable bottom 15, which performs harmonic oscillatory movements in the vertical plane, turning at an angle relative to the axis 17. Due to the oscillatory movement of the bottom 15, the load into it through the tray 2 and the cargo to be transported becomes fluid in which the mobility of the particles of the load is increased, and the bonds between them are reduced. By changing the properties of the bulk load in the bottom 15, it is facilitated by scooping it with the buckets 6. The oscillation frequency of the movable bottom 15 is determined by the gear ratio of the gear pair 7 and 8, and its amplitude is determined by the position of the finger 14 in the holes on the bottom 15. The values of these parameters are selected depending on from the properties of the transported cargo. The proposed implementation of the shoe expands the technological capabilities of the elevator and increases its reliability. An invention of a shovel bucket of a bucket elevator containing a corpur, the bottom of which is hinged on it, an eccentric, kinematically connected to the shaft of the end element, and a pull for kinematic connection of an eccentric with the bottom, characterized in that in order to expand technological capabilities by adjusting the amplitude of oscillation bottom and increased reliability in operation, the bottom is fixed at one end on the housing by means of an axis parallel to the shaft of the end element and at its other end there are a number of holes for pivotally about fixing them end thrust.
