Abstract

Release of compressed material as well resulting arches provide cyclic movement erosion ropes systems located inside the container that is derived from the drive that secures them vertically movement.

Description

The invention relates to a device for releasing wood waste in containers. It is mainly sticky material (chips, sawdust).

The up-to-date top-up and release devices of the prior art are poorly effective. The discharge and ivhrer devices are installed at the bottom of the dispensers and do not prevent the pile material from being squeezed, weighted and thus arched. Of the known solutions to this problem, one relies on the systematic filling of the container and thus the movement of the system of ropes vertically interconnected with one another, and the other on the possibility of occasionally piercing the already existing vault with weights. These vibration and air breakers are less effective against arching. Therefore, the capacity of the containers is reduced. Removal of arches is done manually by undermining the bottom, interventions from above and from the service bridges through openings in the sides of the tanks. This increases the number of operating personnel.

These drawbacks are overcome by the wood waste recovery device according to the invention. The device is shown in FIG. 1. Its essence consists in a system of horizontally spaced sets of ropes (2) which are firmly anchored on the walls of the hopper (1). The rope assemblies (2) are interconnected in the axis of the magazine (1) by a drawbar (4) and connected to a drive (3) which ensures the vertical movement of the rope assemblies (2) over the working height H and thereby avoids volume of the container (1).

The invention relates to a device for releasing wood waste in containers. This is mainly sticky material (chips, sawdust, etc.).

The up-to-date roll-up and release devices of the prior art are poorly effective. The discharge devices are installed in the lower part of the containers and do not impede the pressing of the material by its own weight and thus the creation of arches. Of the known solutions to this problem, one relies on the systematic filling of the container and thus the movement of the system of ropes vertically interconnected with one another, and the other on the possibility of occasionally piercing the already existing vault with weights. Also, the vibration and air disruption device is less effective against arching. This capability reduces the capacity of the cartridges. Removal of arches is done manually by undermining the bottom, interventions from above and from the service bridges through openings in the sides of the tanks. This increases the number of operating personnel.

These drawbacks are overcome by the wood waste releasing device according to the invention. Its essence consists in the fact that it consists of horizontally arranged sets of ropes interconnected in the axis of the magazine and firmly anchored on its walls and connected to the vertical drive. The rope assembly may be connected to a linear hydraulic motor, a traction chain guided via a pulley, and a sprocket with a drive shaft or a traction cable guided via a pulley and a rope drum with a shafting shaft.

The advantage of said device is that at relatively low loading costs, it ensures a continuous emptying of the container and eliminates the possibility of creating vaults with a complete turning of the operator's intervention, which has always been associated with the risk of injury. The device can be operated remotely from the operator's station.

An exemplary embodiment of the device according to the invention is shown in the accompanying drawing, where in FIG. 1 is a front view of the device; FIG. 2 is a bottom view of FIG. 3 is a detail A of FIG. 1 in front view, FIG. 4 is a detail A in side view and FIG. 5 is a detail Z of FIG. First

An assembly of ropes 2 which are rigidly anchored to the walls of the magazine 1 are interconnected in the axis of the magazine 1 by a drawbar 4 and connected to a drive 3 which ensures vertical movement of the assembly 2 in the range of working height li. the entire volume of container 1.

The piston of the linear hydraulic motor 3 is elongated by a rod 4 extending through the center of the magazine 1. Ropes 2 are attached to the rod 4. in the range of the working height H, the vaults formed are disrupted simultaneously in the entire volume of the container 1.

The drive shaft 7 is provided with a cable drum 8 and a pulley 5 located in the axis of the magazine 1. By reversing the drive shaft 7 the traction rope 2 moves and thus the vertical movement of the ropes 2 attached to the traction rope 2 located inside the magazine 1 is fixed. The drive shaft 7 may be provided with a sprocket 6 and a pulley 5 located inside the axis of the container 1. By reversing the drive shaft 7, the traction chain moves and thus the vertical movement of the assembly of ropes 2 attached to the traction chain.
