Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dosing device and, more particularly, to grind wood and wood-like materials having a rotatably mounted and drivable shredding assembly and a feed roller. Related to a dosing device for a machine.

[0002]

2. Description of the Prior Art Such a device generally comprises a dosing system which allows only manual (not automatic) feeding of the material to be ground, the material to be ground being pre-connected to an associated conveyor belt. Is supplied to the supply roller. Mechanical dosing is done by fixed or movable conveyors, grabs, front and back dosing machines and similar dosing conveyors.

[0003]

DISCLOSURE OF THE INVENTION In the commercially available charging system, the charging trough and the members for supplying and charging are spatially limited, and the members for supplying and charging are limited. Being present and operating in a manner, there was an essential problem that the operator had to perform extensive, physically extremely difficult, time consuming and even dangerous manual operations . The object of the invention is to eliminate this problem. Therefore, the technical problem of the present invention exerts a fairly rational effect on physical labor and increases the efficiency of work,
This is to make it possible to grind a larger amount for a certain period of time.

[0004]

To this end, the object is to provide a construction according to the characterizing part of the invention of claim 1, namely two chain conveyors which form a substantially horizontal feed gap in the feed hopper (4). Belts (1, 2), each said belt being drivably guided around two chain wheels (15, 16; 17, 18) spaced apart from each other and the upper chain This is achieved by the conveyor belt (2) being displaceable towards the lower chain conveyor belt (1). Further, preferable embodiments of the present invention are described in claims 2 to 7. According to the invention, the material to be shredded, which is supplied by the conveying means of the dosing device, can be conveyed by the lower steel chain conveyor belt to the front of the supply opening, and the material can vibrate in this position. By an upper steel chain conveyor belt attached to
It is further collected, pre-compressed and conveyed in front of the lower toothed feed roller. The material collected by the feed rollers is fed to the shredding assembly without the manual intervention required to achieve this. A great advantage of this aspect of the dosing device of the present invention is that material can be automatically and safely dispensed into the shredder assembly without the use of mechanically complex means.

The components of the dosing device are adapted to cooperate with one another, the speeds of which are hydraulically adapted to one another and are interlocked with one another.

[0006]

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. A rotary shredder assembly 14 is provided within the housing, the rotary shredder assembly being operated by a diesel engine 7 to a V-
It can be driven by the belt drive device 12. In front of the shredder assembly 14 is a supply hopper 4, which tapers in cross section when viewed from the loading direction. An upper steel chain conveyor belt 2 is oscillatingly attached to the feed hopper 4. One of the chain wheels (15) of the steel chain conveyor belt 2 is rotatably mounted on the free ends of two retaining projections 5 extending downwards from the upper part of the hopper 4. The other chain wheel 16 of the chain conveyor belt 2 hangs on the horizontal bearing guide means 6 and is rotatably mounted thereon. Lower steel chain conveyor belt 1
Runs around the two chain wheels 17, 18. Inside the supply hopper 4, two chain conveyor belts 1, 2 are vertically spaced from each other. As shown in FIG. 2, a foldable support table 10, which can be used when necessary, is arranged at the upstream end of the chain conveyor belt 1. Adjacent to the other chain wheel 18 is the toothed feed roller 3. This arrangement with a lower steel chain conveyor belt 1, an upper steel chain conveyor belt 2 and a toothed feed roller 3 shows a shredding assembly 14 for the material to be conveyed, precompressed and fed and also ground. It is effective in moving and supplying to.

The material to be fed and ground is conveyed into the feed hopper 4 by a chain conveyor belt 1 with offset conveying teeth (entraining teeth) 20. The material to be ground is guided and directed by the special shape of the hopper towards the feed opening and the feed roller 3. As mentioned above, the upper chain conveyor belt is mounted in the feed hopper in an oscillating manner. This chain conveyor belt 2 is vertically movable upwards and downwards because the chain wheels 16 are suspended by horizontal bearing guide means 6, this movement being the material supplied for crushing. It is adjusted according to the height of the layers. The material conveyed by the lower steel chain conveyor belt 1 is centered as it enters the feed hopper 4 and is further collected by the upper steel chain conveyor 2 with offset conveying teeth (entraining teeth) 19. The material is compressed and tightly packed with the weight of the upper steel chain belt 2,
As a result, the material is a toothed feed roller 3 which leads directly to a steel chain conveyor belt 1 in which offset conveying teeth 20 extend into a recess carved in the feed roller 3.
Carried in front of.

The dosing device is equipped with an automatically operating overflow system which overrides the manual operation of the feeding system, the overflow system being electrohydraulic when the speed of the shredding system is reduced. The components of the supply means are switched off and when normal speed is restored the switch is switched on again. In the upper region of the base frame 13 of this machine there is a discharge pipe 8 for the ground material. The operation of this machine, including the dosing device, is monitored by the service station 9.
