Description

Technical Field

[0001] This invention patent relates to the field of material transfer technology, specifically to a rotary material conveying chute device. Background Technology

[0002] Material conveying chutes are core guiding equipment in bulk material conveying systems in industries such as mining, metallurgy, building materials, thermal power generation, and port bulk material transfer. They primarily rely on gravity to achieve continuous transfer and transport of powder, granular, and lumpy materials. Existing traditional chutes have several prominent defects in long-term production operation: First, sticky materials such as clay, wet mineral powder, and clinker are very easy to adhere and accumulate on the inner wall of the chute. As the accumulation continues to thicken, it will reduce the flow cross section, causing frequent blockages and bridging. Each blockage requires a complete shutdown and manual clearing, which significantly interrupts the continuous production process and significantly reduces the overall conveying efficiency. Secondly, the disassembly and maintenance of the chute is complicated, the flange connection is prone to leakage, and the disassembly and maintenance process is cumbersome and time-consuming. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology and solve the problems of easy clogging and difficult maintenance of chutes, this invention provides a rotary material conveying chute device, the specific technical solution of which is as follows: A rotary material conveying chute device includes a mounting frame, a feed hopper, a chute, and a discharge pipe. A support frame is mounted on top of the mounting frame. The feed hopper is mounted on top of the chute via a flange. The discharge pipe is fixed to the mounting frame. The chute is mounted on the support frame, with its bottom end penetrating the support frame and inserted into the inner cavity of the discharge pipe. The chute and discharge pipe are coaxially aligned and rotatably coupled. A first driven wheel is sleeved on the outer wall of the chute. A drive motor is mounted on one side of the chute, and a transmission gear is sleeved on the output shaft of the drive motor. A second driven wheel is mounted on the other side of the chute. Both the transmission gear and the second driven wheel mesh with the first driven wheel. A scraper is arranged inside the chute cavity, with its lower end fixed to the inner wall of the discharge pipe. The cutting edge of the scraper abuts against the inner wall of the chute and cleans residual material from the inner wall as the chute rotates.

[0004] Preferably, the second driven wheel and the transmission gear are symmetrically arranged on the left and right sides of the first driven wheel along the central axis of the chute.

[0005] Preferably, the second driven wheel is mounted on the gear frame via a connecting rod, and the gear frame is fixedly mounted on the top of the support frame.

[0006] Preferably, the second driven wheel is sleeved on the bottom of the connecting rod via a bearing.

[0007] Preferably, one or more scrapers are provided; when multiple scrapers are provided, the scrapers are evenly distributed along the circumference of the inner wall of the discharge pipe.

[0008] Preferably, the scraper is made of polyurethane material with a thickness of 10-20 mm.

[0009] Preferably, the drive motor is connected to the support frame via a motor mount.

[0010] More preferably, the motor base is provided with at least two reinforcing ribs at equal intervals along its length.

[0011] Furthermore, preferably, the operating speed of the drive motor is 10-15 r / min.

[0012] More preferably, a sealing gasket is provided at the flange connection between the feed hopper and the chute.

[0013] The beneficial effects of this invention are: 1. The present invention has a simple structure and is easy to assemble and disassemble. The second driven wheel and the transmission gear are symmetrically arranged on both sides of the first driven wheel, thereby ensuring the rotational balance of the chute, reducing mechanical stress, and extending the service life of the components; 2. The present invention is equipped with a static scraper in the inner cavity of the chute. As the chute rotates, the scraper continuously cleans the inner wall of the chute, reducing material residue and reducing the frequency of downtime maintenance. Attached Figure Description

Detailed Implementation

[0016] The specific implementation of a rotary material conveying chute device provided by the present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0017] like Figures 1-2As shown, a rotary material conveying chute device includes a mounting frame 6, a feed hopper 1, a chute 2, and a discharge pipe 3. The mounting frame 6 has a support frame 4 on its top; the feed hopper 1 is mounted on top of the chute 2 via a flange; and the discharge pipe 3 is fixed to the mounting frame 6.

[0018] Preferably, the chute 2 is rotatably mounted on the support frame 4, with its bottom end penetrating the support frame 4 and inserted into the inner cavity of the discharge pipe 3. It is worth emphasizing that the chute 2 and the discharge pipe 3 are coaxially arranged and rotatably fitted together.

[0019] To achieve the rotation of the chute 2, a first driven wheel 201 is fitted onto the outer wall of the chute 2. A drive motor 5 is installed on one side of the chute 2, and a transmission gear 501 is fitted onto the output shaft of the drive motor 5. A second driven wheel 4021 is installed on the other side of the chute 2 (the second driven wheel 4021 and the transmission gear 501 are symmetrically arranged on the left and right sides of the first driven wheel 201 along the central axis of the chute 2). Both the transmission gear 501 and the second driven wheel 4021 mesh with the first driven wheel 201: the output shaft of the drive motor 5 drives the transmission gear 501 to rotate, synchronously driving the first driven wheel 201 to rotate, thereby realizing the rotation of the chute 2. The second driven wheel 4021, which also meshes with the first driven wheel 201, can form a double-sided symmetrical support transmission with the single-sided transmission gear 501, thereby improving the smoothness of the chute 2's rotation operation, reducing the radial off-center mechanical stress generated by gear meshing, reducing the wear between various transmission components, and effectively extending the service life of the entire machine's parts.

[0020] The second driven wheel 4021 is mounted on the gear frame 402 via a connecting rod, and the gear frame 402 is fixedly mounted on the top of the support frame 4; the second driven wheel 4021 is sleeved on the bottom of the connecting rod via a bearing (not shown in the figure).

[0021] Preferably, a scraper 202 is arranged in the inner cavity of the chute 2, and the lower end of the scraper 202 is detachably fixed to the inner wall of the discharge pipe 3; the cutting edge of the scraper 202 is attached to and abuts against the inner wall of the chute 2, and cleans the residual material on the inner wall as the chute 2 rotates.

[0022] It is worth noting that one or more scrapers 202 can be provided according to actual needs; when multiple scrapers 202 are provided, they are evenly distributed along the inner circumference of the discharge pipe 3. The scrapers 202 are made of polyurethane material, and the thickness is preferably 10-20mm.

[0023] Preferably, the drive motor 5 is connected to the support frame 4 via a motor mount 401.

[0024] More preferably, the motor base 401 is provided with at least two reinforcing ribs at equal intervals along its length direction, which are used to improve the overall structural rigidity and load-bearing strength of the motor base 401, suppress the operating vibration of the drive motor 5, prevent the motor base 401 from deforming, and ensure the stability of the meshing accuracy of the transmission gear 501.

[0025] Furthermore, preferably, the operating speed of the drive motor 5 is 10-15 r / min.

[0026] More preferably, a sealing gasket is provided at the flange connection between the feed hopper 1 and the chute 2 to prevent material leakage.

[0027] In use, the material enters the chute 2 through the feed hopper 1. At the same time, the drive motor 5 is started, which drives the first driven wheel 201 and the second driven wheel 4021 to rotate synchronously through the transmission gear 501, driving the chute 2 to rotate at a speed of 10 to 15 r / min. The scraper 202 located in the inner cavity of the chute 2 scrapes off the material adhering to its inner wall as the chute 2 rotates. The scraped material is discharged from the discharge port of the discharge pipe 3 through the bottom of the chute 2 to avoid accumulation.

[0028] When maintenance is required, the flange between the feed hopper 1 and the chute 2 can be removed to separate them, thereby completing the cleaning or replacement of the chute 2.

[0029] It is worth noting that the discharge angle of chute 2 can be adjusted to accommodate materials with different dryness / wetness, particle size, and angle of repose characteristics. Operators only need to replace the support frame 4 with one of different sizes and specifications, changing the assembly angle between the support frame 4 and the mounting frame 6, and simultaneously adjusting the overall inclination slope of chute 2. Properly adjusting the inclination angle can control the material's downward flow velocity, prevent material accumulation and blockage in the chute, and reduce the impact and wear of the material on the inner wall of the chute, meeting the needs of conveying various types of bulk materials.
