The combined device is a landfill working machine designed for work on large landfills in power plants, ports, smelters, coke ovens, cement plants, chemical plants and other landfills of raw materials and construction materials. It is a reloading device that replaces the previously separate devices (recipient and depositor), two more expensive, heavier and in terms of time incompletely used devices on landfills. In addition, it enables the homogenization of heterogeneous raw materials and thus guarantees a more economical and uniform operation of the plant. The advantages of the device are as follows:
- Savings in purchase costs
- Reducing the number of servers
- Increasing the area of the landfill served by one device
- Greater elasticity and driveability
- Lower production costs
Depending on technological needs, the following operating modes can be achieved on the combined device:
- Landfill disposal
- Taking (loading) from the landfill
- Taking (loading) from the landfill
- Combined: release and take (capacity replenishment) transport directly to the consumer, with simultaneous taking of material from the landfill
- Combined: disposal and throughput, where the transported material is divided into two parts: one is disposed of and the other is transported to the consumer
Combined devices can be designed according to customer specific requirements if necessary.
The combined device consists of the following basic structural groups:
- Lower line in portal design
- Rail running gear
- Arrow with roto wheel and conveyor
- Mechanism for rotating the upper structure
- Hydraulic installation (boom lifting, lifting court, spreading of dump carts and rail grippers)
- Counterweight arrow
- Loading trolley with conveyor
- Dump truck
- Electrical equipment
- Central lubrication
The steel structure is made of solid and box girders. The connection between the main assemblies is articulated. Two drives installed on the upper structure of the revolving platform are used to rotate the boom with the revolving platform. At the end of the output shaft, which is passed through the revolving platform, there is a gear that is connected to the toothed crown of the central bearing, placed on the lower platform. The ring gear is fixed to the lower platform, so that rotation is provided by the relative rolling of the small drive gear on the ring gear of the central bearing.
