Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a deflector chute for charging raw materials onto a pallet truck in a mining section of a sintering machine.

With respect to this charging technique, in recent years, importance has been placed on the adjustment of particle size segregation in the thickness direction of the raw material layer, as well as the adjustment of the compaction of the surface of the charging raw material. The present invention relates to this consolidation adjustment.

(Prior Art) The particle size segregation adjustment with respect to the type of the charging raw material and the particle size composition is performed by changing the angle of the inclined surface of the chute body of the deflector chute. On the other hand, the consolidation of the surface of the charging raw material is adjusted by changing the angle of the cut plate attached to the lower end of the chute body.

However, conventionally, since the cut plate was fixedly attached to the chute body, the consolidation adjustment could not be performed independently of the grain size segregation adjustment. For example, if you want to make the chute main body gentle and swing the cut plate tilt angle in the pallet advancing direction with respect to the vertical, the cut plate will follow the chute body and will be swung in the opposite direction. . On the contrary, when the inclination of the chute main body is made steep and the inclination angle of the cut plate is desired to be swung in the direction opposite to the traveling direction of the pallet with respect to the vertical, the result is that the same is swung in the opposite direction.

Also, a pipe extending in the lateral direction, which is attached to the lower end of the cut plate and comes into contact with the surface of the charging raw material on the pallet truck, is important for determining the raw material charging layer thickness. Wears out. If the operation is continued while the wear is progressing, sufficient consolidation adjustment cannot be performed. However, in the past, since the pipe was welded and fixed to the cut plate, the entire worn pipe had to be replaced. Since the pipe is sometimes made of expensive stainless steel to prevent the adhesion of raw materials, replacement of the pipe is expensive in terms of material cost and construction cost. Was becoming.

(Problems to be solved by the invention) The object of the invention is to adjust the consolidation of the surface of the raw material charged on the pallet truck in the sintering machine ore feeding section without being affected by other independent requirements. , So that it can be implemented in the most appropriate state.

(Means for Solving the Problems) In order to solve the above problems, according to the present invention, a deflector chute for charging raw materials supplied from a raw material feeder in a sintering machine ore feeding section onto a pallet truck. A deflector having a chute body and a cut plate attached to a lower end portion of the chute body, wherein the cut plate is tiltable so that a relative angle with respect to an inclined surface of the chute body can be changed. In the chute, a laterally extending pipe for contacting the raw material surface of the pallet truck is attached to the cut plate, the pipe is located rearward of the front surface of the cut plate, and the lower end of the pipe is cut. It is mounted so as to be located below the lower end of the plate, and its mounting rotation angle position can be changed. There is provided a deflector chute for charging a raw material of a sinter feeding section of the sintering machine.

(Operation) Since the cut plate in the deflector chute of the present invention can be tilted so that the relative angle with the inclined surface of the chute body can be changed, the inclined surface of the chute body is set to a certain angle for adjusting the grain size segregation. Even if it does, an arbitrary inclination angle for the consolidation adjustment can be taken independently thereof.

In addition, even if the pipe attached to the lower end of the cut plate is worn at the contact part with the raw material surface, if it is reattached and used while changing the attachment rotation angle position, a new contact is made each time. Parts are provided,
The useful life of a single pipe can be very long.

(Embodiment) FIG. 1 is a schematic side view showing an embodiment of a raw material charging deflector chute according to the present invention together with a raw material feeder and a pallet truck.

The raw material 3 cut out from the surge hopper 1 by the roll feeder 2 which is a raw material feeder is loaded onto the pallet truck 6 through the deflector chute having the chute body 4 and the cut plate 5 attached to the lower end thereof, and is uniformly loaded. It is assumed that the raw material charging layer is thick.

The chute body 4 is for adjusting the particle size segregation of the raw material,
It is possible to tilt so as to change the angle of the inclined surface, and it is also possible to move up and down and move. Also,

It is fixed to the drive shaft 15 supported by. Drive shaft 15,
For example, it may be connected to a worm speed reducer or the like that can be operated by a manual handle. In this case, the worm reducer or the like is fixed to the mounting rib 7 of the chute body 4 so that it can follow various movements of the chute body 4.

When the drive shaft 15 is rotated counterclockwise in FIG. 1, the cut plate 5 is moved in the traveling direction of the pallet truck 6 (rightward in FIG. 1) by the action of the first and second links 11 and 12. Get dumped. When the drive shaft 15 is rotated clockwise, the cut plate 5 is swung in the direction opposite to the traveling direction of the pallet truck 6 (leftward in FIG. 1). These operations can be performed independently of the tilting of the chute body 4. Therefore, the charging material consolidation adjustment can be performed independently of the particle size segregation adjustment.

The worm speed reducer and the like have a self-locking mechanism so that the inclination angle of the cut plate 5 is not changed by the pressure reaction force of the raw material.

FIG. 2 is an enlarged side view showing the cut plate 5, the tilting rib 9 and the pipe 8. The lower edge of the tilting rib 9 of the cut plate 5 is curved downward in a concave shape, and the pipe 8 is engaged with the curved portion.
