Description

[Detailed explanation of the invention] (a) Technical field to which the invention pertains The present invention enables the required number of transport bodies each having an arbitrary number of rotatable rollers to be stacked up and down, and to be delivered. This invention relates to a rod feeding device for a rod mill, which allows an arbitrary number of rods to be placed on a rod body, fed out, fixed to each conveyor, and then easily fed into the chamber of the rod mill main body.

(b) Explanation of the prior art In general, in a rod mill that uses the falling impact of the rod to crush raw ore, as the rod repeatedly rolls and falls, collisions with the raw ore, between the rods, and even inside the main body are caused. As rods gradually wear out with use due to impact with walls, etc., and their crushing capacity inevitably decreases, rods must be supplied quickly, and they must be installed to suit the site of use. Since it is long and heavy, it is difficult to handle, and there is a desire for something that solves these problems.

(C) Purpose of the invention The present invention consists of stacking a required number of transport bodies each consisting of an arbitrary number of rotatably arranged rollers vertically, and then moving the upper transport member over the rollers of the lower transport member. It can be easily fed out by rolling through rollers, and furthermore, a rod for the rod mill is placed on the top stage of the rod, guided into the main body of the rod mill, and inserted through the discharge port. The object of the present invention is to provide a rod feeding device for a rod mill that can be easily fed, and that allows the extension distance to be changed as appropriate by changing the number of stages of the conveyor depending on the installation location, and that also saves space. do.

(d) Structure of the invention The present invention is a rod mill in which a supply port and a discharge port face each other horizontally. The upper stage is stacked up and down so that it can be held, so that it can be fed out, and when it is fed out, the end of the upper stage transport body is fixed with a lock pin through a guide installed upright on the lower stage transport body, and the top stage transport body is attached to the rod mill. The rod is formed so as to be able to hold the rod facing the discharge port and placed on the topmost conveyance body, and is arranged adjacent to the conveyance body group in order to supply an arbitrary number of rods onto the topmost conveyance body. This is a rod feeding device for a rod mill consisting of a rod mounting table and a rod mounting table.

(E) Description of Examples In order to clarify the gist of the present invention,
One embodiment will be described with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention, in which a conveying body 1 (hereinafter simply referred to as a conveying body) that can be fed out in different stages using rollers is a lower conveying body 11 and an upper conveying body. It consists of 12.

The lower conveyor 11 has two L-shaped steel pieces slightly longer than the entire length of the rod 2 to be used, which are laid flat back to back, and a plurality of rollers 111 are rotatably disposed between them. A plurality of guides 112 are fixed to the outer walls of both L-shaped steels 111 facing each other to prevent the upper conveyor 12 from derailing when rolling, etc. A lock pin 113 is attached to the guide 112 at the right end).
An insertion hole 114 is provided therethrough.

Note that the lower conveyor 11 is close to the outside of the trommel H provided at the discharge port E that opens on the axis of the shell body C that rotates around a horizontal axis, and further,
The rod mill L is fixed to a fixing frame (not shown).

Next, the upper conveyor 12 has two L-shaped steel pieces approximately 30 to 50% longer than the lower conveyor 11 arranged in parallel, and a plurality of rollers 111 rotatably arranged between them. The total width of the rollers 111 of the lower conveying body 11 is made slightly smaller than the interval between the guides 112 provided facing the lower conveying body 11.
It is arranged so that it can roll on the top.

In addition, an insertion hole 114' having the same diameter is inserted near one end of the L-shaped steel (the rightmost end in FIG. 1) at a position overlapping with the insertion hole 114 provided through the guide 112 of the lower conveyor 11. It is set up. In addition, side plates 115 having approximately half the length of the entire length of the upper conveyor 12 are fixed to both side walls of the left side of this L-shaped steel in FIG. It is prevented.

Further, a rod mounting table 21 is provided adjacent to the upper conveyor 12 and having the same height as this, and the rods 2 before replenishment etc. are placed on the mounting table 21.
In addition, in order to prevent the rod 2 from falling on the rod holder 21, a pair of supports 21 are provided on the upper transport body 12 side.
1,211 is disposed on the rod mounting base 21 so as to be freely fitable and removable.

In the rod supply device configured as described above, when it is necessary to replenish the rods 2, the upper conveyor 12 is moved to the right end in FIG. The required number of upper rods 2 to remove 211 from the upper transport body 1
2, the support columns 211, 211 are fitted and erected, and then the upper conveyor 12 is inserted into the insertion hole 1 of the upper conveyor 12.
14' overlaps with the insertion hole 114 of the lower conveying body 11, and by inserting the lock pin 113, the upper and lower conveying bodies are fixed in a stepped configuration.

Next, the rod 2 is inserted into the chamber of the shell main body C through the discharge port E by hand or by using an extruder (not shown) or the like, and is then fed.

Next, FIG. 2 shows a second embodiment of the present invention, in which, due to the installation location, etc., if only one stage of feeding is insufficient as in the first embodiment, the middle conveyor 13 is used. Lower carrier 11 and upper carrier 12
A structure interposed between the middle conveyor 3
, 22 L-shaped steels are arranged in parallel, and a plurality of rollers 111 are rotatably arranged between them, and a guide 112 and an insertion hole 114 are provided in the same way as the lower conveyor 11, and a As shown in Figure 2, the upper conveyor 1
2 and an insertion hole 11 provided at the right end of the middle conveyor 13.
4' and the insertion hole 114 provided through the guide 112 are fixed to each other by fitting a lock pin 113, and the lower transport body 11, the middle transport body 13,
It is formed to fix the upper conveyor 12 in a stepped manner.

In the second embodiment of the present invention constructed as described above, the rod 2 can be transported to a longer distance with great ease.

(f) Effects of the invention The present invention stacks the required number of conveyors one on top of the other so that the lower one can hold the upper one, and forms them in different levels. By placing the rod for the rod mill on top of the upper conveyor and rolling each conveyor in sequence, the upper conveyor rolls on the rollers of the lower conveyor, and the upper conveyor rolls via the rollers of the lower conveyor. Therefore, even heavy rods can be transported in a rolling manner in a rolling manner, so that they can be fed deep into the rod mill body easily, quickly, and accurately, resulting in labor savings.

Therefore, it is possible to use the installation location effectively, and since the conveyor is of the type that is stacked vertically, the extension distance can be adjusted to any desired length by easily selecting the number of stages according to the installation location. In addition, it is safe and secure because the upper conveyor is fixed with the lower conveyor in sequence as it expands, and it saves energy because it does not require complicated operating devices. Since the above-mentioned problems are solved very simply and effectively, it must be said that the practical benefits brought about by the present invention are extremely large.

The specific shape, number of stages, structure, etc. of the conveyor of the present invention may be arbitrarily determined within the scope of achieving the above-mentioned purpose of the present invention and the operation and effect, and these changes may be made at any time. Needless to say, this does not change the gist of the present invention.
