Abstract

PURPOSE:To always carry out appropriate and efficient raking for a conveyor provided at its front end with a raking cutter, by rotatably attaching, to the front end of the conveyor, lift arms which rotatably carry the raking cutter. CONSTITUTION:A flexible conveyor 8 which is wound around a conveyor arm 6 is arranged such that bellows in each side plate 8a of the conveyor 8 expand in a sector-like shape when the conveyor turns around a wind roller 6b at the front end section of the arm 6 so that the intervals of the bellows in the outer section of the side plate 8a is enlarged. In this arrangement lift arms 10 are attached to both sides of the front section of the above-mentioned arm 6 by means of a supporting shaft 9, and is made vertically rotatable by a hydraulic cylinder 11. Further, a raking cutter 12 is rotatably attached to the front end of the lift arms 10 so that it may be driven by a hydraulic motor 14 through a chain, etc. With this arrangement a desired purpose may be attained by suitably adjusting the inclined angles of the conveyor arm 6 and the lift arms 10, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a collecting device comprising a scraping cutter provided at the tip of a conveyor for collecting bulk materials such as soil and coal, and particularly relates to a rotating device for the scraping cutter. .

Conventionally, this type of collecting device has a device in which a scraping cutter is rotatably mounted on an extension of an axis connecting the centers of two rollers around which a collecting conveyor is wound, and the rotation axis of the scraping cutter is was fixed at a predetermined position on the above extension line.

Therefore, in the collection device developed by the present inventors, a flexible conveyor made of rubber is used as the collection conveyor, so that the partition plate constituting the conveyor expands once as it goes around the rollers. In addition, in the conventional fixed type scraping cutter, loose materials are scraped into the closing area of the partition plate, and a part of it is thrown up. Not only will the scraping be scattered outside and not enough scraping can be done on the sampling conveyor, but if the sampling conveyor moves upwards and upwards and its inclination angle changes, the scraping cutter and the partition plate of the sampling conveyor may There were drawbacks such as the relative position of the material being changed, making it impossible to efficiently collect the material at the optimal location within the collection conveyor.

The present invention has been made in order to eliminate the drawbacks of the conventional collection device described above, and its purpose is to always reliably scrape the loose material scraped by the scraper cuckoo into the optimum location on the collection conveyor. To provide a scraping cutter rotating device in a collecting device for a pile of bulk materials, which can efficiently scrape whatever state the collecting conveyor is inclined.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a movable beam, which is constructed so as to be movable while being supported by a retaining wall (not shown) of a storage area for waste materials such as coal C. Two rails 2 are laid on the moving beam 1, on which a cart 3 runs. A turning table 4 is rotatably mounted on the truck 3, and a main body frame 5 mounted on the turning table 4 can be turned left and right.

The base of a conveyor arm 6 is pivotally attached 6a to the upper end of the main body frame 5, and can be rotated up and down by an elevation sill 7.

A flexible conveyor 8 made of rubber is wound around the conveyor arm 6, and its two sides move continuously in the direction of arrow A, that is, in the direction of the main body frame 5. As is clear from FIGS. 2 to 4, this flexible conveyor 8 includes a plurality of partition plates 8B oriented perpendicularly to the moving direction at appropriate intervals, and integrally formed on both sides of the partition plates 8a. It is composed of a bellows-shaped side plate 8b. In the flexible conveyor 8, when the tip of the conveyor arm 6 wraps around the roller 6b (see FIG. 5), the bellows of the side plate 8b expands into a fan shape, and the partition plate 8
The outer spacing of a widens, and immediately returns to the original spacing when moved toward the upper surface.

A lift arm 10 is attached to both sides of the tip of the conveyor arm 6 via a support shaft 9, and a hydraulic sill.
11, it can be rotated up and down.

A scraping cutter 12 is provided at the tip of the lift arm 10.
The lift arm 10 is rotatably attached to the lift arm 10.
It is designed to be rotated in the direction of arrow B by a hydraulic motor 14 via a suitable transmission means such as a chain 13 disposed therein (see FIG. 4).

As is clear from Fig. f53, the above-mentioned scraping cutter 12
is provided with a large number of scraping claws 15, and scraping screws 16 are provided symmetrically on both sides of the scraping claws 15.

17 is a side cutter;
2 is fixed to both ends of a shaft 12a (see FIG. 5) so that they rotate together, and spiral pawls 17a are provided on the outer surface thereof.

In addition, 18 in FIG. 1 is a conveyor for a moving beam.

Next, the sampling operation by the above-mentioned embodiment device will be explained. .

First, the movable beam 1, the cart 3, etc. are moved to appropriate positions, the elevation sill 7 is extended and contracted to adjust the inclination angle of the conveyor arm 6, and the scraping cutter 12 provided at its tip is used to remove the pile. Position it at the scraping location. Note that the conveyor arm may be rotated as necessary.

Next, let the hydraulic cylinder 11 work 7 to arm 10
is rotated by an appropriate angle around the support shaft 9, and set at a position suitable for being pulled into the flexible conveyor 8, as shown in FIG.

Subsequently, the flexible conveyor 8, moving beam conveyor 18, etc. are driven, and the hydraulic motor 14 is operated to rotate the scraping cutter 12. The scraping cutter 1
2 rotates, the coal C in front corresponding to the width of the side plate 8b of the flexible conveyor 8, the conveyor arm 6, etc. is scraped up by the scraping screw 16 toward the scraping claw 15 in the center, and The coal C is scraped into the flexible conveyor 8 together with the coal C in the claw 15 portion.

The coal C taken in by the flexible conveyor 8 is transferred in the direction of the main body frame 5, dropped onto the moving beam conveyor 18, and is discharged as appropriate.

In the first embodiment, the collecting device is of a type mounted on a moving beam and a trolley, but the present invention is not limited to this, and a self-propelled collecting device such as a reclaimer may be used.

In addition to the above-mentioned flexible conveyor, the collection conveyor may be any conveyor such as an apron conveyor or a pan conveyor, as long as it can transport the bog material while tilting freely.

Furthermore, both the sills 7 and 11 are interlocked to automatically adjust the rotation angle of the lift arm 10 according to the inclination angle of the conveyor arm 6, and to control the scraping cutter 12 so that it is always at the optimum position. Good too.

As described above, in the present invention, since the scraping canter is rotatably mounted, scraping can be carried out efficiently and always in the optimum condition, regardless of the condition of the collection conveyor, such as its inclination or piles. .
