In general, when a conveyed object is lifted and conveyed, a carry-in compare, a vertical movement compare, and a discharge compare are connected and connected. A belt conveyor is used for the carry-in conveyor and the carry-out compare, and the conveyor transfer path is often made a closed type in order to prevent dust and the like. However, in a belt conveyor in which a conveyed object is placed and moved on the upper surface of the belt, the conveyed object adhered to the surface of the conveyed belt adheres to the inverted belt at the inverted discharge side end and enters a return path, and the path is conveyed. there was to be dropped into. For this reason, frequent maintenance such as stopping and cleaning the transport system has to be performed. This problem was more pronounced when the transported product contained moisture.
[0003]
In view of the above, there is also provided one in which a carry-in compare and a carry-out compare are formed by a scraper type compare. In the scraper type conveyor, since the scraper scrapes off the conveyed material accumulated in the lower trough, there is no problem of being returned to the return side of the compare.
[0004]
Also, when using a bucket elevator as lifting conveyor, conventionally, since the bucket is to pass a stable conformation bare-or we receive the conveyed object at a position elevated in position, the formation position of the transfer part is It was often set at a relatively high position from the reversal rising portion of the bucket elevator.
[0005]
[Problems to be solved by the invention]
However, when performing horizontal or inclined conveyance with a scraper-type conveyor, when transferring abradable powder such as coke powder or glassy granules, if the moving speed is high, the chain or case part of the compare may be early. There is a problem of wearing.

The present invention has been made in view of such a point, and an object of the present invention is to provide a small-sized lifting / ejecting type comparison apparatus having good transport efficiency.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a carry-in compare and a discharge compare, each of which is formed by a scraper conveyor, and a lift-transport compare is constituted by a full-discharge bucket elevator, and is transported to a lower inverted portion of the lift-transport compare. to form a rope throttle portion, the discharge-side reversing portion of the carry compare with the to plunge into the transport cord aperture portion, the upper reversing part of the conveying compare constituted by the upper side by the overhang of the input-side reversing portion of the unloading compare lifting The constriction section of the transport cable is formed by a guide wheel coaxially arranged with a chain wheel located at a discharge side reversal portion of the carry-in conveyor .
[0009]
Effect of the Invention
According to the present invention, the transfer rope narrowing portion is formed at the lower inverted portion of the lifting transport compare constituted by the full discharge bucket elevator, and the discharge side inverted portion of the carry-in comparison is rushed into the transport rope narrowed portion. Is located in a state of overhanging the bucket moving space of the lifting / conveying compare. As a result, the discharge section of the carry-in compare is located in the casing of the lift transport compare. Further, the discharge portion of the lifting transport compare is overhanged above the input portion of the output compare , and the transport rope narrowing portion is formed by a guide wheel coaxially arranged with a chain wheel located at the discharge-side inverted portion of the input conveyor. Therefore, the casings of the carry-in conveyor, the lifting conveyor, and the carry-out compare can be integrally formed, and the overall size can be reduced.

The lifting conveyor (2) comprises a bucket elevator composed of a pair of endless chains (6) and buckets (7) fixedly mounted at fixed intervals between the endless chains (6) (6). The unloading conveyor (3) is composed of a pair of endless chains (8) and a scraper conveyor (9) fixedly mounted between the endless chains (8) at regular intervals. It consists of.
[0012]
As shown in FIG. 2, the connecting connection between the discharge section (10) of the carry-in conveyor (1) and the input section (11) of the lifting conveyor (2) constitutes a discharge-side inverting section of the carry-in conveyor (1). The guide wheel (13) supported coaxially with the rotating shaft of the chain wheel (12) is pressed against the endless chain (6) of the lifting conveyor (2), thereby causing the lifting conveyor (2) to rotate. A narrowed portion (14) is formed near the lower end. By arranging the discharge-side reversing part of the carry-in conveyor (1) so as to protrude into the squeezing part (14), the discharge-side reversal part of the carry-in conveyor (1) is moved to the bucket moving space of the lifting conveyor (2). It is located in the state of overhang on the upper side of.
[0013]
A discharge section (15) formed on the upper side of the lifting conveyor (2) is connected to an input section (16) formed on the unloading conveyor (3). In this case, the upper reversing portion (17) of the lifting conveyor (2) is overhanged so as to be located above the input section (16) of the unloading conveyor (3). In this case, a guide mechanism such as a guide rail or a guide wheel can be used as a mechanism for changing the movement path of the lifting conveyor (2).
[0014]
The lifting / discharging type conveyor device is formed by enclosing a carry-in conveyor (1), a lifting / conveying conveyor (2), and a carry-out conveyor (3) with a casing (18) integrally formed.
[0015]
In the lifting / discharging type comparing apparatus formed in this way, the transported object loaded into the loading conveyor (1) is conveyed to the discharging section while being scraped by the scraping plate (5), and is loaded into the loading section of the lifting transport conveyor (2).
