Description

[Detailed Description of the Invention] This invention particularly relates to an inclined conveyor capable of conveying irregularly shaped fluid objects such as gravel, other granular materials, and powder down a steep slope.

Conventionally, in order to convey the above-mentioned fluids to high places, it was necessary to use bucket conveyors, screw conveyors, or other special conveyors with containers that can securely accommodate them, and installation and loading were difficult. Even when a simple belt conveyor can be used, the inclination is limited to about 18°, and conveyance at an inclination greater than that is almost impossible or extremely inefficient.

On the other hand, excavated soil made of clay is highly adhesive and the conveyor must be cleaned in preparation for the next conveyance. The problem is that it cannot be used.

Additionally, the present inventor has developed a steeply inclined belt conveyor that allows the belt to slacken at regular intervals and transports the conveyed items by storing them in the recesses created by the slack. (For example, as shown in the specification and illustrations of Utility Model Application No. 58-61317 (Utility Model Application No. 59-187610)), in this system, the belt reversal curve due to the belt winding drum at the upper end of the conveyor is too gentle. However, the problem is that belt slack is corrected early on, making it easy for loads to spill from the sides.

This invention aims to provide an inclined conveyor that solves the above problems.In particular, a chain foil is pivotally supported at both upper and lower ends of both sides of the frame, and an endless chain is wound around the chain foil. A belt mounting rod is attached to the belt, and between each of the above-mentioned mounting rods, the end of a belt piece made of a flexible member whose central part hangs down in a concave shape with respect to the end is fixed in a rotatable state, A turning roll for turning the belt is supported at the upper end of the frame, and a number of guide rolls are supported on a pitch circle concentric with the upper chain wheel at the lower arc-shaped periphery to extend the belt. It is characterized by a structure that makes it difficult to move.

To explain in detail the embodiment shown below, chain foils 2 and 3 are pivotally supported at the left and right upper and lower ends of a long frame 1, respectively, and an endless chain 4 is wound around the chain foils 2 and 3 over the entire length. A chain wheel 2 at the upper end is rotationally driven by a motor 5 attached to an arbitrary part of the frame 1. Guide rollers 6 are rotatably supported between the links of the chain 4 or on the outside at regular intervals, and when the chain is driven, the guide rollers 6 contact a rail-shaped chain guide 7 made of angles attached to the frame 1 and roll on the upper surface thereof. By doing so, the load applied to the chain 4 is supported and the running trajectory of the chain is maintained.

Brackets 8 of a predetermined height are attached to each of the chains at regular intervals so as to protrude from the outer periphery of the chain via auxiliary brackets 21, and a pair of rod-shaped belts is installed between the brackets 8 on both sides. Mounting rods 9a and 9b are installed in parallel and close to each other,
A rectangular or square belt having a width approximately equal to that of the adjacent belt mounting rod 9b or 9a and made of a material containing flexible rubber or resin having water resistance and abrasion resistance. Piece 10
The front and rear ends of the chain 4 are fixed to each other, and these many belt pieces 10 connected endlessly around the outer periphery of the chain 4 form one endless belt 11 as a whole.
It consists of

Clip tubes 13 are attached to each belt mounting rod 9a, 9b.
are rotatably fitted, and the ends of the belt piece 10 are inserted into two mounting plates 14 which are tangentially abutted to the clip tube 13, and are fixed with rivets, bolts, or the like. Closely supported clip tube 1
Spacer 1 between 3 and 13 to prevent cargo from spilling
2 is accommodated. Further, on both side edges of the surface of the belt piece 10, there are a large number of rubber or resin materials whose side surfaces are trapezoidal, fan-shaped, or triangular, and which form inclined surfaces such that the front and rear adjacent surfaces approach or contact each other as the belt piece curves. The side protrusions 10a are arranged in a straight line and protruded by adhesion or integral molding. These side protrusions 10a are used to prevent the conveyed items placed on the belt 10 from spilling out, and when the belt piece 10 forms a recess on the upper surface due to slack as shown in FIG. In this structure, the front and rear surfaces are adjacent to each other to form a side wall having a shape corresponding to the slack of the belt piece 10.

On the other hand, on the back side of the belt piece 10, a plurality of rows of reverse protrusions 10b are protruded from the lower peripheral edge of an auxiliary frame 16, which will be described later, and abut against a belt extrusion guide roll 19 pivotally supported thereon. It is made of rubber or resin and is adhered to the belt piece 10 or fixed by integral molding,
The reverse protrusions 10b and 10b are arranged in the vertical direction so as to have cuts, so that the belt piece 10 is not obstructed from curving.

The upper end of the frame 1 connects the chain wheel 2 to the drive shaft 3.
An auxiliary frame 16 is attached, which is made up of two left and right plates or structures that are pivotally supported by the frame 1. The belt piece 10 and the belt attachment rod 19 are configured to rotate around the outer periphery of the semicircular surface.

That is, the chain 4 and the belt attachment rod 19 supported by the chain 4 are both driven upward along the straight inclined upper surface of the frame 1, but the auxiliary frame 16
At the tip of the chain 4, the chain 4 is wrapped around the foil 2 and rotated in the opposite direction along its circumference. However, although the belt piece 10 stores the conveyed object inside the slack and rises straight up diagonally, when it reaches the upper end (tip) position of the auxiliary frame 16, it rolls onto the rotating roll 18 provided at the tip. The belt 11 twists and turns suddenly, causing the load to fall.
is extended and moved along the semicircular circumferential surface of the auxiliary frame 16.

At this time, the reverse protrusion 10b protruding from the back side of the belt 11 is kept in an arcuate shape in contact with the guide rolls 19 which are supported in large numbers on the periphery of the auxiliary frame 16, and the reverse protrusion 10b
The height of the back surface (the surface located on the inside) of the belt is approximately equal to or higher than that of the clip tube 13, so there is no level difference between the clip tube 13 and the back side of the belt, and the rolls 18, 1
The clip tube 13 will not collide with the clip tube 9.

On the other hand, a chain foil 3 is attached to the lower end of the frame 1.
A guide roll 17 coaxial with the belt 11 is supported so that the belt 11 does not interfere with chain drive. In particular, an iron cover 22 is installed on the side of the auxiliary frame 16 to cover the above-mentioned mechanisms and to prevent soil removal and other loads from falling into the equipment.
is attached, and furthermore, a cleaner 24 consisting of a scraper or a cleaning roll is provided below the peripheral edge of the auxiliary frame 16 to circumscribe the stretched belt piece 10 and remove clay soil etc. attached thereto. There is.

According to the conveyor of the present invention constructed as described above, the belt pieces constituting the belt form a bucket-shaped concave portion for loading by the slack on the inclined upper surface, and furthermore, the belt pieces constituting the belt form a bucket-shaped concave portion for loading cargo on both sides. Since the side protrusions forming the side walls are provided to prevent cargo from spilling, the cargo loaded below the conveyor can be efficiently carried upwards. In addition, at the upper end of the conveyor, the belt piece is expanded by rapid rotation, so that even granular and powdered objects can be transferred to other places without causing spillage. In addition, since the belt can be extended in an arcuate shape, it is possible to remove deposits from the belt using a scraper or a cleaning roll, which has the advantage of further increasing conveyance efficiency.

In addition, the conveyor of the present invention can be carried from deep locations such as underground excavations by sequentially connecting multiple stages, that is, by receiving and retransferring objects that have fallen from one conveyor to the next conveyor. The soil can be transported on a steep slope, that is, with a small number of conveyors and a small conveyor space.
