BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-type continuous conveyor suitable for use in vertical earth and sand conveying machines for transporting large amounts of earth and sand generated during the formation of underground spaces to the surface.

0002

2. Description of the Related Art Conventionally, various vertical earth and sand transport machines have been developed as earth lifting equipment. Examples include screw conveyors, bucket conveyors, grab bucket conveyors, belt conveyors, and muddy water pumps. A conventional example of a belt conveyor will be explained with reference to FIGS. 12 and 13. Reference numeral 207 denotes a pedestal, which includes upper and lower guide rollers 205 attached to the upper and lower surfaces of the pedestal 207, a drive sprocket 203 attached to one end of the pedestal 207, and the pedestal 207. An endless belt 201 made of fiber or rubber is supported so as to be cyclically movable via a driven sprocket 204 attached to the other end. 20 again
Reference numeral 2 denotes a transported object such as earth and sand, 206 a transported object loading section, and 208 a transported object discharge section.

When conveying the conveyed object 202, the drive sprocket 203 is driven to circulate the endless belt 201 in the direction of the arrow, and the conveyed object 202 that has fallen from the conveyed object loading section 206 onto the endless belt 201 is removed. The conveyed object 202 is transported in the direction of the conveyed object discharge section 208, and when it reaches the conveyed object discharge section 208, the endless belt 201 is reversed downward, and the conveyed object 202 on the endless belt 201 is caused to fall downward.

0004

[Problems to be Solved by the Invention] The belt conveyor shown in FIGS. 12 and 13 has the following problems. That is, (
1) When conveying the conveyed object 202, the endless belt 201 does not restrain the conveyed object 202 piled up in a chevron shape on it so that it does not move, so if the belt conveyor is inclined, the conveyed object 202 may move or spill. Spillage or scattering of the conveyed object 202 also occurs when the conveyed object 202 is dropped from the downstream end of the endless belt 201 in the conveying direction. (2) The belt conveyor itself cannot actively take in the conveyed object 202, and the conveyed object 202 must be loaded onto the endless belt 201 manually or mechanically, resulting in poor conveyance efficiency. (3) Belt conveyors are only capable of continuous conveyance in a horizontal or slightly inclined state; vertical conveyance is not possible.

The present invention has been proposed in view of the above-mentioned problems, and its purpose is to prevent the movement and spillage of conveyed objects during conveyance. Transport efficiency can be improved. Furthermore, it is an object of the present invention to provide a belt-type continuous conveyor that can carry out vertical conveyance.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the belt-type continuous conveyor of the present invention includes two parallel endless chains, and two parallel endless chains arranged at equal intervals in the longitudinal direction. A conveyance belt consisting of a plurality of connecting rods installed on the ground, a plurality of formworks attached to each of the connecting rods, and a deformable endless belt placed outside the movement locus of each of the formworks.
The conveyor belts are arranged side by side, and each conveyor belt is provided with a conveyance take-in section at one end, and a conveyance object discharge section is provided at the other end of each conveyance belt.

[0007]

[Operation] The belt-type continuous conveyor of the present invention is constructed as described above, and drives the endless chains of one and the other conveyor belts, and connects each connecting rod, each formwork, and a deformable endless belt. is circulated between the driving sprocket and the driven sprocket, and the formwork of one and the other conveyor belt is lowered and approached at the conveyance material intake section, making it possible to deform the conveyance materials such as earth and sand that are piled up here. The objects are taken in and joined via an endless belt to form a pocket, and the object to be conveyed is supported in a state of being wrapped by these formworks and the endless belt between them, and is conveyed toward the object discharge section. Near the object discharge section, one conveyance belt is separated from the other conveyance belt, and at the conveyance object discharge section, the other conveyance belt is reversed in the downward direction, and the conveyed object is discharged from the formwork.
