Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and more particularly to a rotary feeder. Background Technology

[0002] In long-distance belt conveyor transport of bulk materials, intermediate transfer stations are inevitably needed to transfer materials and change their transport direction. The conventional solution is to use electric tee boxes or other feeders for transfer, but these transfer devices typically require a large installation space. If electric tee boxes are used, the transfer station needs a high ceiling; if other feeders are used, especially with multi-point feeding, multiple downstream receiving belt conveyors need to be arranged side-by-side. Due to the feeder's own structure, the spacing between these conveyors needs to be large, thus requiring a significant area and resulting in high project costs, sometimes even failing to meet installation requirements. Summary of the Invention

[0003] To address the aforementioned technical problems, a rotary feeder is provided.

[0004] The technical means employed in this invention are as follows:

[0005] A rotary feeder includes a rotary support, an arc-shaped track device, a rotary device, and a belt conveyor. The rotary support includes a rotary seat and a rotary bearing. The axis of the rotary seat is perpendicular to the horizontal plane, and the axis of the rotary bearing is on the same straight line as the axis of the support. The outer ring of the rotary bearing is fixedly mounted on the top surface of the rotary seat. The axis of the arc-shaped track device is on the same straight line as the axis of the rotating part. The rotary device includes a rotary structure, a rotary drive device, and a wheel. The axis of the rotary structure is parallel to the horizontal plane. The bottom surface of one end of the rotary structure is fixedly mounted on the inner ring of the rotary bearing. The fixed end of the rotary drive device is fixedly mounted on the other end of the rotary structure. The wheel is fixedly mounted on the output end of the rotary drive device and can rotate around its axis under the drive of the output end of the rotary drive device. The wheel is rolled on the arc-shaped track device. The belt conveyor is coaxial and fixedly mounted on the rotary structure.

[0006] Furthermore, the arc-shaped track device includes a track beam device and an arc-shaped track body; the axis of the track beam device is perpendicular to the horizontal plane; the axis of the arc-shaped track body and the axis of the rotating part are on the same straight line, and the bottom surface of the arc-shaped track body is fixedly installed on the top of the track beam device; the wheel is rolled on the arc-shaped track body.

[0007] Furthermore, the belt conveyor includes an idler assembly, a conveyor belt, and an idler drive device; the idler assembly includes several idler rollers, each including a head roller and a tail roller, the several idler rollers being evenly distributed along the axis of the rotary structure and rotatably mounted on the rotary structure; the conveyor belt is sleeved on the idler assembly and can rotate under the drive of the idler assembly; the fixed end of the idler drive device is fixedly mounted on the rotary structure, and the output end of the idler drive device is fixedly mounted on the head roller and can drive the head roller to rotate.

[0008] Furthermore, the belt conveyor also includes a tensioning device; the fixed end of the tensioning device is fixedly installed on the rotating structure, and the output end of the tensioning device is fixedly installed on the tail roller and can drive the tail roller to move away from the head roller.

[0009] Furthermore, it also includes a guide trough; the guide trough is fixedly installed on the rotary structure, and the output end of the guide trough is positioned opposite to the top surface of the conveyor belt.

[0010] Compared with the prior art, the present invention has the following advantages: 1. In this invention, the bottom surface of one end of the rotary structure is fixedly installed on the inner ring of the rotary bearing, and the other end of the rotary structure is rolled on the arc-shaped track device through a wheel. That is, multi-point feeding is achieved by fixing the tail and rotating the head, which greatly reduces the installation space and saves engineering land and investment costs. At the same time, this invention can be widely used in industries such as coal, docks, mines, chemicals, and power.

[0011] 2. In this invention, the tensioning device can keep the conveyor belt taut at all times, preventing the conveyor belt from becoming loose and thus unable to be driven to rotate by the idler roller group. Attached Figure Description

[0022] Specifically, the outer ring of the slewing bearing 301 is fixedly mounted on the slewing seat 302 by bolts.

[0023] In this embodiment, the arc-shaped track device 4 includes a track beam device 402 and an arc-shaped track body 401; the axis of the track beam device 402 is perpendicular to the horizontal plane; the axis of the arc-shaped track body 401 is on the same straight line as the axis of the rotating part, and the bottom surface of the arc-shaped track body 401 is fixedly installed on the top of the track beam device 402; the wheel 202 is rolled on the arc-shaped track body 401.

[0024] In this embodiment, the belt conveyor 1 includes an idler roller assembly 104, a conveyor belt 102, and an idler roller drive device 105. The idler roller assembly 104 includes a plurality of idler rollers, each including a head roller and a tail roller. The plurality of idler rollers are evenly distributed along the axis of the rotary structure 201 and are rotatably mounted on the rotary structure 201. The conveyor belt 102 is sleeved on the idler roller assembly 104 and can rotate under the drive of the idler roller assembly 104. The fixed end of the idler roller drive device 105 is fixedly mounted on the rotary structure 201, and the output end of the idler roller drive device 105 is fixedly mounted on the head roller and can drive the head roller to rotate.

[0025] Specifically, the belt conveyor 1 also includes a tensioning device 101; the fixed end of the tensioning device 101 is fixedly installed on the rotary structure 201, and the output end of the tensioning device 101 is fixedly installed on the tail roller and can drive the tail roller to move away from the head roller. The tensioning device 101 is existing technology in the field and will not be described in detail here.

[0026] Specifically, it also includes a guide trough 103; the guide trough 103 is fixedly installed on the rotary structure 201, and the output end of the guide trough 103 is arranged opposite to the top surface of the conveyor belt 102.

[0027] The working principle of this embodiment: Fix the slewing seat 302 to the ground, so that the center of the slewing bearing 301 is aligned with the discharge port of the upper belt conveyor 1.

[0028] The arc-shaped track device 4 is straddled above the next-stage belt conveyor 1 and fixed to the ground. The tail end of the rotating structure 201 is fixed to the inner ring of the slewing bearing 301, while the head of the rotating structure 201 is rolled onto the arc-shaped track body 401 via wheels 202. Driven by the rotating drive device 203, the wheels 202 of the rotating device 2 roll on the arc-shaped track body 401, causing the rotating device 2 to rotate around the center of the slewing bearing 301. Since the belt conveyor 1 and the rotating structure 201 are fixed together, the belt conveyor 1 and the rotating structure 201 rotate together on a fixed axis. When the discharge port of the belt conveyor 1 rotates to different positions, it can discharge material to different next-stage belt conveyors 1, completing the material transfer function.

[0029] This embodiment uses a three-in-one motor as the rotary drive device 203 and a rotary bearing 301 as the rotary central shaft, realizing the function of changing the unloading position of the feeder by rotation. It makes full use of its compact structure and is an ideal choice in compact working conditions.

[0030] Material from the previous belt conveyor 1 is directly unloaded onto the conveyor belt 102 via the guide chute 103. Driven by the idler drive device 105, the conveyor belt 102 slides on the idler roller group 104, carrying the material into the next belt conveyor 1. When the receiving point is changed, the material conveying is stopped first, and then the rotary drive device 203 drives the wheel 202 to roll on the arc track body 401. Driven by the wheel 202, the belt conveyor 1 and the rotary structure 201 rotate together with the wheel 202 around the rotary bearing 301 as the central axis. When the head of the belt conveyor 1 rotates to the receiving point of the next belt conveyor 1, the wheel 202 stops rotating and is fixed, thus realizing the change of the unloading point.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
