The movable cover 8 arranged at the hinge joint of the first conveying section 1 and the second conveying section 2 can always shield the gap between the first conveying section 1 and the second conveying section 2 when the second conveying section 2 rotates, namely, no matter how much degree the second conveying section 2 rotates, the movable cover 8 can always shield the gap between the first conveying section 1 and the second conveying section 2. Of course, when the movable cover 8 is arranged, the movable cover 8 can be arranged at the hinge position of the first conveying section 1 and the second conveying section 2, the movable cover 8 can be arranged at the hinge position of the second conveying section 2 and the third conveying section 3, and the movable cover 8 can be arranged at the hinge positions of the first conveying section 1 and the second conveying section 2, the second conveying section 2 and the third conveying section 3, so that the movable cover is arranged according to actual requirements by a person skilled in the art.
With continued reference to fig. 4 and 5, the movable cover 8 includes a stretchable fabric and at least two backbones 81. Both ends of the frame 81 are respectively connected with both ends of the hinge shaft one by one, the first and last frames 81 are respectively fixed with the protective cover 7, for example, the first and last frames 81 are respectively fixed with the third cover 73 and the second cover 72 at the hinge position of the third conveying section 3, the first and last frames 81 are respectively fixed with the second cover 72 and the first cover 71 at the hinge position of the second conveying section 2, and the first and last frames 81 are respectively fixed with the second cover 72 and the first cover 71. Two adjacent skeletons 81 are connected by a telescopic cloth.
The cross section of the skeleton 81 may be arc-shaped, as shown in fig. 4 and 5, of course, the skeleton 81 may further include an arc-shaped piece and two flat pieces, the end faces of the arc-shaped piece where the two arc-shaped pieces are located are integrally connected with one end of the flat piece respectively, and the other ends of the two flat pieces are connected with two ends of the hinge shaft respectively, so that when the movable cover 8 is unfolded or contracted, the outer peripheral surface of the movable cover is a cylindrical surface, the connection is smoother, and meanwhile, the flat pieces are arranged, so that the faces of the two flat pieces of the movable cover 8 are more attached to the side face of the protective cover 7, the installation is more convenient, and the space is also saved.
The number of the backbones 81 may be two, three, four, etc. … …, which is not limited in the embodiment of the present application. By way of example, fig. 4 and 5 show a schematic structural diagram of the first conveyor section 1 and the second conveyor section 2 with eight skeletons 81 and the second conveyor section 2 and the third conveyor section 3 with nine skeletons 81. Of course, the greater the number of skeletons 81, the stronger the structure of the protective cover 7, which can extend its useful life.
The two adjacent frameworks 81 are connected through the telescopic cloth, the telescopic cloth not only has the function of shielding the space below, but also has the function of connecting the last framework 81 with the next framework 81 in the process of rotating the second conveying section 2 or the third conveying section 3 so that the last framework 81 pulls the next framework 81 to rotate. The arrangement of the telescopic cloth can enable the expansion and condensation of the movable cover 8 to be more convenient and rapid, and enable the whole movable cover 8 to have a better shielding effect.
Of course, the movable cover 8 may further include only a plurality of frameworks 81, if the frameworks 81 include an arc-shaped sheet and two planes, the end surfaces of the arc-shaped sheets are integrally connected with one end of a flat sheet respectively, the other ends of the two flat sheets are connected with two ends of the hinge shaft respectively, the length of the flat sheet of each framework 81 is gradually increased along the clockwise direction or the anticlockwise direction, a first baffle extending upwards is disposed on the peripheral wall of one side of the arc-shaped sheet of the previous framework 81 adjacent to the next framework 81, a second baffle extending downwards is disposed on the inner peripheral wall of one side of the arc-shaped sheet of the next framework 81 adjacent to the previous framework 81, and when the movable cover 8 is installed, the first baffle can be clamped into the second baffle, so that when the movable cover 8 is unfolded, the first baffle can pull the second baffle to enable the movable cover 8 to be unfolded smoothly, and when the movable cover 8 is folded, due to the gradual increase of the length of the flat sheet, the previous framework 81 can be inserted into the inner cavity of the next framework 81, and the movable cover 8 can be condensed smoothly.
Optionally, the protective cover 7 and the movable cover 8 are made of transparent materials, so that the running condition of the materials on the conveyor belt can be conveniently monitored.
In practice, the folding conveyor device also comprises a base 9. The base 9 is arranged on the placing surface, and the first conveying section 1 is arranged on the supporting surface of the base 9. Referring to fig. 1 to 5, the base 9 is a groove, and the first conveying section 1 is disposed on an inner bottom surface of the groove. When the folding transmission belt device comprises a second telescopic mechanism 6, the first transmission section 1 is hinged with the second transmission section 2, two ends of the hinge shaft can be respectively connected with two side walls of the groove in a rotating mode, and therefore the hinge shaft is more stable, and the fixed end of the second telescopic mechanism 6 is connected with the upper end face of the side wall of the groove. The base 9 is arranged, so that the folding conveyor belt device is an independent whole, and the folding conveyor belt device can be moved to any working occasion by moving the base 9, so that the folding conveyor belt device is more convenient to use and wider in applicability. Of course, when the base 9 is not provided, the fixed ends of the first conveying section 1 and the second telescopic mechanism 6 of the device can be fixed on a certain fixed occasion, such as the bottom surface of a carriage of a truck, and when the truck is driven to different occasions, the folding conveyor belt device can be carried to different working occasions.
In practical application, as shown in fig. 5, a top cover 10 is further disposed at an end of the third cover 73 facing away from the second cover 72, so as to protect the material conveyed by the top of the third conveying section 3 from being polluted or damaged. The top cover 10 includes a main body and an outer edge, the main body is in the shape of a quadrangular prism, the bottom surface of the quadrangular prism is in the shape of a right trapezoid, a plane where the height of the right trapezoid is located is connected with one end of the third cover 73, which is far away from the second cover 72, and the outer edge is arranged on an end surface where the bottom edge of the right trapezoid is located.
In this specification, each embodiment is described in a progressive manner, and the same or similar parts of each embodiment are referred to each other, and each embodiment is mainly described as a difference from other embodiments.
