Abstract

PROBLEM TO BE SOLVED: To easily discharge even a claylike material and moreover a material which is apt to flow relatively, by a specified amount, by providing a device comprising a bottom board, a moving frame and transport boards which are layed in a style almost perpendicular to the moving frame, fixing the bottom board, and circulating the moving frame while it is made upside-down. SOLUTION: A bottom plate is of a fixed type and has a structure in which a fore end is curved downward and extends to a foremost end. A moving frame 3 is composed of a combination of low height boards fixed to rollers 4 of a conveyor. Transport boards 5 are mounted on the bottom board 2 at a specified distance and held between both sides of the moving frame 3, and are moved together with the frame 3. A material to be conveyed which is placed on a front part of the transport board 5 is pushed forward in accordance with the movement of the board. The material is dropped when it comes to the fore end since the bottom board 2 terminates at the foremost end and the moving frames serving as side boards are inverted. With such a constitution where the bottom board is not moved together with the material to be transported, even a claylike material can be dropped at a specified position easily.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a viscous material conveying device.

[0002]

2. Description of the Related Art A viscous material refers to a so-called clay material, but here refers to various soils, powders, granules, and other viscous substances having properties similar to those. The purpose of the present invention is to convey these objects, but it goes without saying that conveying other objects using the present apparatus is included in the right.

[0003] A hopper and a feeder are usually used when treating or improving soil or the like, or when continuously supplying or receiving a predetermined amount. this is,
It continuously discharges batch-type materials, for example, temporarily stores a large amount of soil intermittently removed by a power shovel or yumbo, and discharges it from a belt conveyor etc. almost quantitatively continuously from there. And so on.

In such a case, a belt conveyor is conventionally provided below a hopper having an opening at an upper portion, and soil or the like falls onto the belt conveyor from an outlet below the hopper, and is conveyed quantitatively by the conveyor. You. At this time, the amount of the soil falling on the belt conveyor is determined by the size of the outlet below the hopper, and even if a large amount of soil or the like is stored in the hopper, it can be discharged relatively quantitatively.

[0005]

However, in the case where there is no consistency such as sand, the above-mentioned conventional apparatus may be used. A phenomenon occurs in which the thick substance does not fall, and even if it falls, it cannot be transported by the conveyor and remains at that position. This is because the viscous material slips on the lower conveyor belt, and only the belt moves. In such a case, the transported object cannot be sent at all, or an interval affecting downstream processes is opened.

[0006] In order to prevent such a situation, there is a so-called bucket conveyor. In this method, a bucket is rotatably fixed to a conveyor, and is forcibly transported by the bucket. Although this can certainly be transported in a bucket without slipping, it is difficult to drop the transported object in the bucket to a predetermined position. That is, even if the bucket filled with the viscous material is inverted, the viscous material does not easily fall because the bottom of the bucket is evacuated. In particular, since the viscous material is forcibly scraped off with a bucket, it is basically difficult to fall.

[0007]

In view of the above situation, the present inventor has completed the present invention as a result of intensive studies, and the features of the present invention are a bottom plate, a moving frame, and the like. A carrier plate provided at a predetermined interval on the moving frame at a substantially right angle to the moving direction, wherein the moving frame goes around the top and bottom of the bottom plate, and the bottom plate is of a fixed type. .

[0008] The hopper is a portion for temporarily storing the conveyed object, and a conveyed object is sent out by a conveying plate, which will be described later, in a substantially constant amount. It is for absorbing the fluctuation of the amount. The upper part is a mere opening, and the lower part is opened so as to drop an object to be conveyed to an area pressed and conveyed by a conveying plate.

[0009] The bottom plate is the one on which an object to be conveyed (a viscous object or the like) slides and moves, and in a conventional belt conveyor, the belt itself moves to convey the object to be conveyed. There is a decisive difference from the past, where the base on which the goods are placed does not move. This bottom plate is made of metal, plastic or the like, and need not be special. The bottom plate may exist only in a substantially straight portion or in a portion where the moving frame descends. Further, a wall surface may be provided on a side surface parallel to the traveling direction.

The moving frame body is configured to rotate around the bottom plate in the vertical direction, and is like a peripheral portion of a chain conveyor. This may be a ladder shape, a double ladder shape, or a wall surface (unnecessary if provided on the bottom plate) in the left-right direction. Basically, it is only necessary that the conveyed object can be rotated and moved without preventing the object from dropping from above to the bottom plate.

The transport plate transports the transported object by its movement. The transport plate is fixed to the moving frame and presses and transports the transported object in the moving direction according to the movement of the movable frame. This is just a plate and need not be specially shaped. This is fixed at a predetermined interval substantially perpendicular to the traveling direction of the moving frame.

Further, a tunnel having a length equal to or longer than the fixed interval of the transport plate may be provided at a portion where the transport plate enters and exits below the hopper. This is to prevent the object to be conveyed from the part where the conveying plate comes out of the hopper and from the part where the conveying plate comes out from the hopper and to overflow to the next object to be conveyed even when the object to be conveyed has a relatively large flow rate. It is.

As another configuration of the present invention, the side wall of the hopper may be vibrated when the transferred object is difficult to drop downward from the hopper. For example, it is caused to vibrate by a motor. Further, an inclined baffle may be provided inside the hopper to reduce a shock when the transported object is thrown into the hopper from above.

Further, a rubber plate may be provided at the bottom of the transport plate so as to prevent stones or the like from being caught between the bottom plate and the transport plate, or a pebble shield such as a front portion of a train may be provided.

Further, a wall surface may be provided on a falling portion of the transported object so that the transported object is dropped to a predetermined position without being scattered around.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 shows one of the devices 1 of the present invention.
It is an outline perspective view showing an example. The bottom plate 2 is of a fixed type, is curved downward at the tip end, and is interrupted at the tip end. The moving frame 3 is fixed to a roller 4 of a conveyor and has a low plate shape. The transport plate 5 is attached to the moving frame 3 at a predetermined interval, and moves together with the moving frame 3. The roller 4 is driven by a rotary drive (not shown) like a normal roller conveyor. The left and right wall surfaces 6 at the bottom of the hopper are located above the movable frame 3. Although the transported object is not shown in this figure, the transported object located at the front of the transport plate 5 is pushed forward as the transport plate moves. Then, at the forefront, the bottom plate disappears and the side wall disappears, so that only the front and rear transport plates 3 and the moving frame are present around the transported object and fall. With this configuration, even clay can be dropped to a predetermined position.

In the example shown in FIG. 1, the bottom plate is provided only in the upper half, but may be provided in the entire periphery. In this case, although the transportability of the transported object is inferior, the bottom plate does not move in the same manner as the transported object, so that the transported object falls down very easily as compared with a conventional bucket conveyor or the like.

In the example of FIG. 1, there is a difference between the height of the moving frame 3 and the height of the transport plate 5, but the height may be the same if the structure of the conveyor permits. If the transport amount is small or even if the side wall of the moving frame is large, if it can easily go around,
That is enough. Further, the moving frame may not have any portion such as a side wall, and may be constituted only by a chain and a roller.

FIG. 2 shows an example in which tunnels 8 are provided at exits before and after the hopper 7 (however, a rear portion is not shown). A tunnel 8 in which the left, right, top and bottom are sealed forward from the exit of the hopper 7
Is provided. The length of the tunnel 8 is longer than the fixed interval of the transport plate 5. Without the tunnel 8, the transported object overflows from the hopper outlet between the transport plates. Since the distance between the transport plates 5 is longer than the interval between the transport plates 5, at least one transport plate is always present in the tunnel 8, and the overflow is stopped there. The transport amount of the transported object is defined by the entrance of the tunnel.

[0020]

The present invention described in detail above has the following significant effects. By this tunnel and the fixed bottom plate, a predetermined amount can be easily discharged, whether it is clay-like or relatively easy to flow. It can be easily improved from the conventional chain conveyor. Compared with a screw conveyor or the like, the structure is simple, and even if it is large, it is very inexpensive.
