BACKGROUND OF THE INVENTION 1. Field of the Invention

[0003] The prior art belt conveyor cleaning machines based on the interval cleaning method and utilizing for cleaning the space created by placing the connecting rail of the central parts at such a height above the substructure that it is possible to insert the digging member of the cleaning device they do not comply with the current requirement of clearing long-distance track transport routes, both in terms of depth of cleaned space and performance in cubic meters of cleared material per hour. The performance aspect of the equipment is closely related to the labor intensity of the operator, which is very strenuous in the present equipment, since the operator controls several movements of the working member, which he manipulates in the very confined space of the central belt conveyor parts. Technological plant innovation leads to the use of increasingly wide conveyors with a relatively low construction profile of the structure and thus a minimum space between the lower branch of the conveyor belt and the substructure where the abrasion of the lower zone and other material is deposited and accumulated.

To clean these areas, either universal machines with modified digging organs or special equipment are used. The common feature of these devices is the digging body in the form of a long slender heel, which is inserted under the connecting rail of the central parts of the long-distance belt conveyor. Such a digging organ limits the depth of the cleaned space by its construction length, during digging the material accumulates in the front part of the digging organ due to considerable stickiness of clay-gathered material and thus

- 2 233 273 utilization of the entire ladle space of this organ, which in turn leads to a decrease in the hourly performance parameter in cubic meters of purified material. Manipulation of such a long and long digging body is very demanding, not only when inserting into the space of the middle part construction, but also during emptying, especially when emptying to the upper zone of long-distance belt conveyor. The kinematics of the equipment is given by the movement of the system of arms controlled in the vast majority of equipment by three hydraulic cylinders, similarly to the classic shovel excavators. Telescopic pull-out devices make the whole kinematics easier to operate, but only for cleaning via the connecting rail located directly on the sleepers of the long-distance conveyor structure. In summary, the kinematics of the equipment used for cleaning the area under the long-distance tracked conveyor structure, particularly for cleaning under the connecting rail, is very demanding for the operator of the equipment, which has to coordinate several basic movements in coordination. which significantly affects device performance.

The above-mentioned drawbacks are solved by a device for interval cleaning of long-distance tracked conveyor routes mounted on a mobile, wheeled or caterpillar chassis provided with a fixed frame according to the invention, which is based on the rear part of the support bracket anchored in the front part by means of a pivot. pivot swinging mounted rear part of the carrier rod. The front part of the support bracket is fitted with a common pin into which the swinging bracket is pivotally anchored. Furthermore, the right and left connecting arms are pivoted to the common pin.

The front portion of the support rod and the adjusting hydraulic cylinder are pivoted to the opposite portion of the right connecting arm and the front portion of the adjusting rod and the piston rod of the adjusting hydraulic cylinder are pivotably anchored to the opposite portion of the left connecting arm. The adjusting rod is rotatably anchored by its upper part in the digging member and the swinging arm is rotatably anchored by its lower pin in the digging member. A working hydraulic cylinder is pivotally mounted in the central part of the supporting boom, whose piston rod is pivotally anchored in the middle part of the swing arm and the piston rod of the lifting cylinder, which is anchored by its rear part to the fixed frame of the mobile chassis.

The advantage of this device is that it allows simplified control of the digging organ, especially when sliding under the belt conveyor structure, where there is minimal space between the belt conveyor structure and the substructure. By connecting two ogram parallels, the device keeps the digging body always in the specified horizontal position, regardless of the movement of the support arm controlled by the hydraulic lift cylinder or the movement of the swing arm controlled by the working hydraulic cylinder. Moreover, when sliding under the belt conveyor construction, the movement can only be controlled by a working hydraulic cylinder and the lift hydraulic cylinder for this part of the operation can be left uncontrolled or only corrected by adjusting the boom position _; and hence the digging authority. The adjusting hydraulic cylinder is used only to correct the operation of the parallelogram system when the device is operating on a plane not parallel to the longitudinal track construction. The operation of the device is therefore simpler and less tiring over the cycle than the operation of conventional excavators or long-distance conveyor cleaners, and can be used to achieve higher performance. In addition, the system of parallelograms also guarantees energy savings, because when the digging member is inserted under the belt conveyor construction, when the hydraulic cylinder is lifted, the load of the booms also contributes to the pushing force (digging). it is relieved by means of parallelgrams by the reaction of the mass of the digging organ filled with the excavated material. Discharging of the digging organ can be carried out forced, again in a horizontal position, which is advantageous for conditions of sticky clay materials of brown coal quarries in Czechoslovakia.

AND

An exemplary embodiment of a device for interval cleaning of long-distance conveyor tracks with a horizontally moving cleaning element is shown schematically in the attached drawing.

The device for interval cleaning of long-distance conveyor tracks with a horizontally moving digging body is mounted on a mobile wheeled or caterpillar chassis 21, on whose fixed frame 22 the rear part of the boom 2 is pivotably anchored in its front part by means of a frame pin J. The front part of the boom 2 is fitted with a common pin 5, into which the upper part of the swing arm 16 is rotatably anchored. Furthermore, the right connecting arm 6 and the left connecting frame are rotatably anchored to the common pin 5. 273 ntf 7. The front part of the support rod 4 and the adjusting hydraulic cylinder 9 are anchored to the opposite part of the right connecting arm 6 and the front part of the adjusting rod 11 and the piston rod 12 are anchored to the opposite part of the left connecting arm. hydraulic The adjusting rod 11 is pivotally anchored by its upper part 13 with the upper pin 13 in the digging member 15 and the swing arm 16 is rotatably anchored with its lower part 14 by the lower pin 14 in the digging member 15. a hydraulic cylinder 17, the piston rod of which is pivotally anchored in the central part of the rocker arm 16 and a stroke hydraulic cylinder 20, which is anchored by its rear part on the fixed frame 22 of the mobile chassis 21.

The rigid frame 22, the boom 2, the carrier rod 4, the right linkage 6 and the digging member 15, the swing arm 16, the adjusting linkage 11, the left linkage 7 form a system of two parallelograms that hold the digging member over the adjusting hydraulic cylinder 9. at any position of the support boom 2 and the swing boom 16 during the entire operating cycle of the device, a fixed horizontal position. The digging member 15 can be adjusted by the adjusting hydraulic cylinder 9 as a correction of the inclination of the working surface of the device relative to the subsoil surface of the longitudinal conveyor belt structure by an appropriate angle without altering the operation of the parallelograms.

This device, in conjunction with the forced discharge of the digging organ, can reliably clean, including the quality of the cleaned space under the long-distance tracked track construction with a side rail, the long-distance tracked transport up to a width of 2500 mm.
