Description

[0001] ARRANGEMENT FOR DRIVING A FEED CONVEYOR, AND CRUSHER [0002]

Industrial technology

The known feed conveyor has a given angular position fixedly installed. The feeding station of the feeding conveyor is provided with a limiting surface that 'cuts' the thickness of the material layer conveyed to the conveying conveyor belt when necessary to avoid excess capacity of the conveyor. Most simply, this limiting surface is a corresponding surface disposed on the conveyor belt in a manner to 'cut' the opening or transverse boom or excess material. The material surface, in particular, must be 'cut off' when a large batch of material is loaded into the supply station from, for example, a bucket of a wheel loader or the like. A problem with this configuration is that the limiting surface is subjected to large forces and wear stresses, which may cause problems with the durability of the limiting surface. 'Cutting' the material layer to an appropriate thickness by the confined surface is achieved by a supply conveyor with sufficient power. The drive motor of the feed conveyor, the power train and the conveyor belt are subject to great stresses, which must be taken into account when dimensioning the component. In addition, the known feed conveyors consume a large amount of energy to limit the thickness of the material layer to be conveyed, which naturally increases the operating cost of the feed conveyor.

The method of the present invention is characterized by monitoring the thickness of the material layer and adjusting the slope of at least the slope of the feed conveyor to adjust the thickness of the material layer, We want to avoid errors.

In order to solve the problem of the present invention, a sensor capable of detecting the velocity and tilt mass of the conveyor is installed so that the problem of thickness recognition can be eliminated and crushing can be performed.

It is an object of the present invention to provide a novel improved feed conveyor drive method, feed conveyor and crusher.

The method of the invention is characterized in that it comprises the steps of monitoring the thickness of the material layer and adjusting the slope of the slope of the feed conveyor at least in order to adjust the thickness of the material layer.

The conveyor of the present invention is characterized in that the supply conveyor is connected to the carrier along the end portion at the side of the at least one turning link and the supply station and the support member has at least one lifting device for adjusting the inclination of the slope of the supply conveyor, Characterized in that the thickness of the material layer is arranged to be adjusted by adjusting at least a part of the slope of the slope

All. The crusher of the present invention is characterized in that the supply conveyor is connected to the carrier at the conveyor end of the side of the supply station by a rotary link and the crusher is located at the side of the supply conveyor on the side of the discharge station which adjusts the slope of the supply conveyor with a slope inclined with respect to the horizontal plane Wherein the thickness of the material layer conveyed to the feed conveyor can be adjusted by varying the slope of the slope of the feed conveyor and the crusher comprises a feed conveyor in the longitudinal direction relative to the crushing unit Characterized in that the position of the drop point of the material flow falling on the feed conveyor at the feed opening of the shredding unit can be adjusted.

The second crusher of the present invention is characterized in that the supply conveyor is connected to the carrier at the conveyor end of the side of the supply station by a rotating link and the crusher is located at the side of the discharge station for controlling the slope of the supply conveyor at a slope Characterized in that it comprises at least one lifting device for raising and lowering the end of the feed conveyor, wherein the thickness of the material layer conveyed to the feed conveyor and the capacity of the conveyor can be adjusted by varying the slope of the slope of the feed conveyor.

The idea of the present invention is that the thickness of the material layer conveyed to the feed conveyor is not limited by the mechanical restraint surface but by adjusting the control parameters of the conveyor. By doing so, the shortest distance from the moving top surface of the conveyor belt at the feeding station to the nearest fixing structure on the conveyor belt

A smaller layer of material is conveyed to the feed conveyor. By adjusting the slope of the slope of the feed conveyor, it can affect the thickness of the material layer being batched on the conveyor belt at the feed station.

The advantage of the present invention is that the thickness control of the material layer does not add any additional stress to the conveyor belt of the feed conveyor and the power train. In addition, no limiting surface is required to limit the thickness of the material layer.

As a result, due to the present invention, the load on the feed conveyor structure is reduced and also the wear stress is made smaller, which makes the feed conveyor more durable than before, and the need for maintenance is reduced. Also, the energy consumption in the feed conveyor according to the invention can be clearly lower than when the material layer being transported is cut off by the mechanical limiting surface.

The idea of embodiments of the present invention is to adjust the speed of the conveyor belt as well as the slope of the slope to adjust the thickness of the material layer. By adjusting the slope of the slope and the speed of the belt, the thickness of the material layer can be effectively influenced.

The idea of embodiments of the present invention is to adjust the slope of the speed and slope of the belt to adjust the capacity of the feed conveyor. In this case, the capacity is adjusted based on the capacity of the crusher or other device following the feed conveyor. For example, the feed capacity required by the crusher may be determined based on the amount of material at the feed opening.

The idea of an embodiment of the present invention is to displace the feed conveyor in the longitudinal direction to control the position of the material flow falling from the conveyor belt at the drop point at the discharge station and also to adjust the position of the drop point.

The idea of embodiments of the present invention is that the feed conveyor comprises at least one measuring device for determining the thickness of the material layer being transported.

The idea of embodiments of the present invention is that the shredding unit comprises a descending station and the position of the descending station is preferably predetermined in terms of operation of the shredding unit. In addition, one or more measuring devices for determining the position of the drop point of the material flow falling at the feed conveyor for the descending station are arranged connected to the feed opening. The operation of the feed conveyor can be controlled by a control unit arranged to adjust the feed conveyor in the longitudinal direction by means of a displacement device which sets the drop point in the determined descent station.

The idea of an embodiment of the present invention is that the feed conveyor has at least one lifting foot and the lifting foot allows the feed conveyor to be driven from the transport position to the working position or vice versa. The lifting foot comprises a linkage which, by the action of the linkage, allows the delivery station of the delivery conveyor to move from the transport position

And at the same time, the entire conveyor is displaced forward in the longitudinal direction. In addition, by the action of the lifting foot, the discharge station of the supply conveyor is displaced from the working position to the transport position during downward driving, and at the same time, the entire conveyor is displaced backward in length. Thereby, the discharging station of the conveyor is moved to the crushing unit

On the other hand, can be driven laterally of the shredding unit in the transport position.

The present invention includes a shredder that can include a movable carrier, a feed conveyor, a shredding unit, and a discharge conveyor. The feed conveyor is used to transport the material to be treated, such as a rock material, into the feed opening of the shredding unit from which the material is transported towards the shredding member which breaks the material into smaller particle sizes. The crushing member is a crushing chamber enclosing the eccentrically rotating vertical crushing cone and the cone, for example, so that the processed material is broken into wedge-shaped spaces between the cone and the chamber and broken into smaller particles. After treatment, the material falls on a discharge conveyor under the crushing fluid,

The material may be transported, for example, into a file at an appropriate exit site.

The feed conveyor includes two or more pulley drums in which a closed loop shaped conveyor belt is disposed. The at least one pulley drum is a so-called drive pulley, which is rotated by the drive motor and the required power transmission member around the longitudinal axis. The pulley drum, to which no rotational force is transmitted, is a so-called returning pulley in which the conveyor belt changes its direction of movement. At the upper part of the feed conveyor, a conveyance section is provided, where the conveyor belt advances in the conveying direction. A return portion is provided at the lower portion of the feed conveyor, where the conveyor belt advances in the return direction. A feed station is installed in the transport section, and the transported material is fed onto the movable upper surface of the conveyor belt. The material is discharged from the transport section in the discharge station. The feed station may include a feed funnel, and the material to be conveyed may be fed into the feed funnel, for example, by another conveyor or wheel loader. The lower surface of the conveyor belt is supported by a plurality of support rolls

Called impact bar.

The default setting for the inclination of the ascending slope of the conveyor can be, for example, 20 ° and can be adjusted, for example, from 18 ° to 25 °. This is to ensure that the fixed surface above the transport section does not contact the transported material layer, but instead the thickness of the material layer is controlled by adjusting the control parameters of the feed conveyor. The manner in which the conveyed material is batched onto the conveyor belt at the feeding station depends, for example, on the internal friction of the material, the friction between the conveyor belt and the material, and the environmental conditions. In addition to the slope of the ascending slope, the speed of the conveyor belt can also be adjusted. If the conveyor is to be driven at a constant capacity, the following principles should be observed during control. The faster the speed of the conveyor belt,

The thickness of the material layer becomes smaller, and vice versa. As the drive motor, for example, a hydraulic motor can be used, and the rotational speed of the motor can be adjusted in a stepless manner. The related description is only intended to explain the spirit of the present invention.
