Description

Изобретение относитс к погрузочным машинам, имеющим исполнитель .ный орган непрерывного действи в виде парных нагребаквдих лап, и может быть использовано в подземных услови х на открытых разработках, на складах сыпучих и кусковатых материалов , в портах на перевалочных базах и т.п.The invention relates to loading machines having a performer. A continuous body in the form of paired feet, and can be used in underground conditions in open-cast mining, in bulk and lumpy materials warehouses, in ports at transshipment bases, and the like.

Известны погрузочные органы непрерывного действи , содержащие приемный стол, конвейер и нагребающие лапы , приводимые в действие, от гидромотора через систему передачtilНедостатком известных погрузочных органов вл етс сложность приводного механизма нагребающих лап.Continuous loading bodies are known, comprising a receiving table, a conveyor and scooping legs, which are driven from the hydraulic motor through a gear system. The disadvantage of known loading bodies is the complexity of the scooping gear drive mechanism.

Известен также погрузочный орган, включающий приемный стол, конвейер, нагребающие лапы клинообразной формы, жестко закрепленные на ос х, расположенных перпендикул рно приемному столу. Лапы привод тс в возвратноповоротное движение через рычаг с помощью двух гидроцилиндров поступательного действи 2.A loading body is also known, which includes a reception table, a conveyor, wedge-shaped scoring legs rigidly fixed on axes arranged perpendicular to the receiving table. The paws are driven backward through the lever by means of two hydraulic cylinders of translational action 2.

Недостатком известного погрузочного органа вл етс то, что он не дает расположить конвейер ближе к погружаемому материалу дл сокращени времени погрузки материёша лапами на конвейер. Расположение гидроцилиндров в передней части приемного стола увеличивает угол наклона приемного стола к грризонтгшьнсй поверхности . Это с одной стороны, создает дополнительные нагрузки на механизм внедрени всего погрузочного органа в штабель погружаемого мате10 риала, с другой стороны, при погрузке материала объем материала, захваченный гребком в процессе перемещени раздел етс на две части. Одна часть доставл етс гребком на A disadvantage of the known loading body is that it does not allow the conveyor to be positioned closer to the material to be immersed in order to reduce the loading time of the material by the paws on the conveyor. The arrangement of hydraulic cylinders in the front part of the receiving table increases the angle of inclination of the receiving table to the grounding surface. This, on the one hand, creates additional loads on the mechanism for inserting the entire loading unit into the stack of the immersed material, on the other hand, when loading the material, the volume of material seized by the paddle during the movement is divided into two parts. One part is delivered to the

15 конвейер, а друга часть отрываетс от гребка и под действием силы т жести устремл етс в сторону, попада под захват второго гребка. С уменьшением угла наклона приемного стола 15, the conveyor, while the other part is detached from the stroke and, under the action of gravity, rushes to the side, falling under the grip of the second stroke. With a decrease in the angle of inclination of the receiving table

20 к горизонтальной поверхности часть материала, уход щего на перелопачивание , уменьшаетс и при расположении приемного стола, близком к горизонтальному , весь материал, захватываемый лапой, погружалс бы на конвейер.20 to the horizontal surface, a portion of the material that is subject to shoveling is reduced, and if the receiving table is located close to horizontal, all the material captured by the paw would be immersed on the conveyor.

Цель изобретени - повышение пройзводительности .The purpose of the invention is to increase productivity.

Claims

The goal is achieved by the fact that in the loading body of a continuous action / including a reception table, a conveyor, scoring legs mounted on shafts with the possibility of reciprocating motion, and a drive of scavenging legs mounted under the receiving table, the driving of scoring legs is made in the form of torque hydraulic cylinders connected with shafts of raking paws and. has a synchronization mechanism. Moreover, the latter is made in the form of asterisks rigidly connected to the shafts of scoring legs connected to each other through a chain. In addition, the synchronization mechanism is made in the form of gears, rigidly connected to the shafts of the scoring legs and connected to each other by means of a fresh rack. The drawing shows the loading body, top view. The loading body of continuous action includes a receiving table 1-, a conveyor 2 driven by an electric motor located in the tail part of the conveyor, scooping legs 3, torque hydraulic cylinders 4 located under the receiving table. The rams of the hydraulic cylinders are rigidly connected with the drive shafts 5, passing through the receiving table, and on them are mounted the base of the foot. The paws in cross-section are wedge-shaped, so that the side of the wall facing the conveyor is vertical and the opposite has a curved shape. The synchronization of the operation of the heating legs is carried out by means of coupling the drive shafts between each other by a chain V-belt or rack-and-pinion gears. The continuous loading body works as follows. When the loading body is inserted into the stack, the scoring feet are put into operation by supplying the working fluid to the cavities of the torque cylinders. Punching feet make a swinging movement. In this case, one paw moves in the direction of the conveyor and, with its vertical side, collects a portion of the material, the other paw moves in the opposite direction and with its wedge-shaped side passes through the material. When the paws are in the extreme position, the flow of the working fluid will be directed to other cavities of the hydraulic moment cylinders. The work cycle will be repeated with the difference that the paw that moved towards the conveyor will now move away from it and, with its wedge-shaped side, pass through the material on the receiving table. The other paw will reload the portion of material onto the conveyor, i.e. move towards the conveyor. The application of the invention provides an increase in productivity of the loading body with raking legs. Claims of the invention 1. The loading body is of continuous action, including a receiving table, a conveyor, scooping pads mounted on shafts with the possibility of a reciprocating motion, and a drive of the scrubbing paws installed under the receiving table, so as to increase productivity , the drive of the scrubbing legs is made in the form of torque hydraulic cylinders connected to the shafts of scoring legs and has a synchronization mechanism. 2. A loading unit according to claim 1, characterized in that the synchronization mechanism is in the form of sprockets rigidly connected to the shafts of scoring legs connected to each other by means of a chain. 3. A loading unit as claimed in claim 1, wherein the synchronization mechanism is made in the form of gears rigidly connected to the shafts of the scooping feet connected to each other by means of a gear rack.
