Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1 to 14, an embodiment of the present invention provides a transmission device, including:

a support frame 1; the support 1 can be mounted on a predetermined plane, which can be the ground or other plane on which the conveyor can be mounted or fixed;

the lifting roller 2 is arranged on the support frame 1, the axis of the lifting roller 2 is horizontal, and the lifting roller 2 can rotate around the axis of the lifting roller;

a first conveyor belt 3 and a second conveyor belt 4; the first end 31 of the first conveyor belt 3 is located on the preset plane, the first end 31 of the first conveyor belt 3 is lower than the second end 32, and the second end 32 of the first conveyor belt 3 extends into the lifting roller 2; the third end 41 of the second conveyor belt 4 extends into the lifting roller 2, the fourth end 42 of the second conveyor belt 4 extends out of the lifting roller 2, and the fourth end 42 of the second conveyor belt 4 is higher than the third end 41; the vertical height from the third end 41 of the second conveyor belt 4 to the preset plane is greater than the vertical height from the second end 32 of the first conveyor belt 3 to the preset plane; and

a driving device 5 for driving the lifting roller 2 to roll circumferentially;

wherein: the first conveyor belt 3 conveys the material from the initial position to the lifting roller 2, the lifting roller 2 is driven by the driving device 5 to roll circumferentially to lift the material to the second conveyor belt 4, the second conveyor belt 4 conveys the material to the target position, and the target position is higher than the initial position.

In this embodiment, by arranging the lifting roller 2 between the first conveyor belt 3 and the second conveyor belt 4, the first conveyor belt 3 has an inclination angle with respect to the horizontal plane, so that the first conveyor belt 3 can convey the material from the initial position into the lifting roller 2, the material can be further conveyed onto the second conveyor belt 4 by the lifting roller 2, the vertical height of the third end 41 of the second conveyor belt 4 from the plane is greater than the vertical height of the second end 32 of the first conveyor belt 3 from the plane, so that the material can be conveyed to a higher position by the lifting roller, but when the material is conveyed onto the second conveyor belt 4, the second conveyor belt 4 has an inclination angle with respect to the horizontal plane, for example, the same as the inclination angle between the first conveyor belt and the preset plane, so that the material can be conveyed to a higher height when conveyed onto the second conveyor belt 4, and the conveyer is not easy to fall off, so that the conveyer greatly reduces the space required by the conveyer and increases the applicability of the conveyer in different use environments.

When the preset gradient of the conveyor belt and the preset height to which materials need to be conveyed are fixed, the whole length of the conveying device is shorter than that of a single conveyor belt, so that the occupied area is greatly reduced. When the preset slope and the preset overall length of the conveyor belt are constant, the height of a target to be conveyed by the conveyor belt is higher than that of a single conveyor belt, so that materials can be lifted higher.

In the embodiment illustrated in fig. 1, the first conveyor belt 3 and the second conveyor belt 4 are arranged in the same direction, i.e. two conveyor belts arranged in the same direction and the lifting drum 2 replace a single conveyor belt, the two conveyor belts being located on both sides of the lifting drum 2. The inclination angles of the two belts may be the same, and the first belt 3 extends into the bottom of the lifting drum 2, and the second belt 4 extends into the top of the lifting drum 2, and there is a height difference between the two belts, that is, a height difference between the second end 32 of the first belt 3 and the third end 41 of the second belt 4, which is a distance lift realized by the lifting drum 2. When the same conveyor belt slope and target height are set, the overall length of the conveyor of this embodiment is shorter than a single conveyor belt, and therefore the footprint is greatly reduced.

Further, the first conveyor belt 3 and the second conveyor belt 4 can be arranged in the same direction and transversely in a collinear manner, namely, the two conveyor belts do not have distance difference in the transverse direction, so that the overall width in the transverse direction is reduced, and the occupied area is saved.

In the embodiment illustrated in fig. 12, the first conveyor belt 3 and the second conveyor belt 4 are arranged in opposite directions, i.e. both conveyor belts are located on the same side of the lifting drum 2, the first conveyor belt 3 extends into the bottom of the lifting drum 2, and the second conveyor belt 4 extends into the top of the lifting drum 2, with a height difference between the two conveyor belts, i.e. the height difference between the second end 32 of the first conveyor belt 3 and the third end 41 of the second conveyor belt 4, which is the distance increase achieved by the lifting drum 2. When the same belt slope and device length are set, the object height that can be conveyed by the conveyor device of this embodiment is higher than a single belt, so that the material can be lifted higher.

In an embodiment of the invention, the lifting drum 2 comprises: a cylinder 21 and a first driven ring 211 and a second driven ring 212 located at the edge of the cylinder 21 and surrounding the axis of the lifting drum 2;

In the embodiment of the present invention, at least two partition plates 213 are radially disposed on the inner wall of the cylinder 21, side walls 22 are respectively disposed on two sides of the lifting drum 2, a space for accommodating the material is formed between the side walls 22 and the partition plates 213, and after the material enters the space, the material is transferred from the space to the top of the cylinder 21 along with the rotation of the lifting drum 2, so as to achieve the transfer in the height direction.

The partition 213 may be inclined or offset with respect to the radial direction of the lifting drum 2, i.e. the partition 213 may be inclined with respect to the inner wall of the drum 21, rather than being perfectly vertical, to facilitate the dumping of the material when reaching the top of the lifting drum 2. The material in the lifting drum 2 can be conveyed from a lower position to a higher position by the partition 213 and further onto the second conveyor belt 4, so that the material can be conveyed to a higher position without falling off easily.
