Description

Technical Field

[0001] This disclosure belongs to the technical field of industrial material conveying equipment, specifically relating to a scraper conveyor for collecting rock wool. Background Technology

[0002] The statements herein provide only background information in relation to this disclosure and do not necessarily constitute prior art.

[0003] Rock wool is a high-performance inorganic fiber material made from natural basalt. It possesses fire-resistant, heat-insulating, sound-insulating, and corrosion-resistant properties, and is widely used in building insulation and fireproofing structures. In the production of rock wool, raw materials such as basalt are melted and then spun into fibers using a centrifuge, followed by processing by a fiber collector and a fiber distributor. During production, uncured raw fibers are easily derailed by wind and air turbulence, falling below the production line. To collect these rock wool fragments, scraper conveyors are typically installed below the rock wool production equipment.

[0004] Existing scraper conveyors use ordinary chain drives, which present several problems. The chain is divided into upper and lower parts, and the relative movement of the scrapers during operation causes rock wool debris to easily get stuck on the scraper bars, leading to deformation. Furthermore, the relative movement of the upper and lower scraper bars poses a safety hazard, potentially causing personal injury or equipment damage. Since scraper conveyors are often over 20 meters long, the excessive chain length and weight make chain tensioning difficult, leading to sagging. Therefore, a drag chain plate is usually installed at the bottom of the scraper conveyor, but the dynamic friction between the drag chain plate and the chain requires wear-resistant plates to reduce wear. Due to the excessive weight of the chain, most of the weight needs to be supported by the drag chain plate, resulting in significant energy waste. The power consumption difference between no-load and loaded operation is not significant, leading to low effective power of the scraper conveyor. Utility Model Content

[0005] The purpose of this disclosure is to provide a scraper conveyor for collecting rock wool that can at least solve one of the aforementioned technical problems.

[0006] To achieve the above objectives, one or more embodiments of this disclosure provide a scraper conveyor for collecting rock wool, including a frame and a transmission mechanism mounted on the frame. The transmission mechanism includes a drive sprocket mounted at the tail of the frame and a driven sprocket mounted at the head of the frame. A transmission chain is mounted on the drive sprocket and the driven sprocket. A base plate is mounted horizontally to the frame at the middle of the frame, and a certain gap is maintained between the base plate and the transmission chain.

[0007] Furthermore, a guide plate is provided on the top of the frame, and the guide plate is in the shape of an inverted cone and is provided on both sides and the tail of the frame.

[0008] Furthermore, the head of the frame is provided with a tensioning sleeve for adjusting the tension of the transmission chain, and the tensioning sleeve is fixed to the frame by bolts.

[0009] Furthermore, the transmission chain consists of an outer link and an inner link that are hinged to each other. An axial baffle is provided on the outer side of the hinge joint between the outer link and the inner link, and a roller is provided on the inner side of the inner link.

[0010] Furthermore, the width of the axial baffle is greater than the horizontal projection area of ​​the hinge joint between the inner and outer links, forming a unidirectional bending limiting structure.

[0011] Furthermore, the drive sprocket is located at the bottom of the base plate and is connected to the reduction motor via the drive shaft.

[0012] Furthermore, the driven sprocket is located on the lower part of the base plate and connected to the driven shaft.

[0013] Furthermore, the central axes of both the driving sprocket and the driven sprocket are located below the base plate, causing the lower section of the chain to hang unsupported below the base plate.

[0014] Furthermore, the transmission chains are arranged parallel to each other on both sides of the frame, and multiple scrapers are vertically installed between the transmission chains at intervals.

[0015] Furthermore, a certain gap is maintained between the scraper and the base plate.

[0016] The beneficial effects of one or more of the above technical solutions are as follows:

[0017] This disclosure utilizes an axial baffle on the transmission chain to ensure that the chain can only bend along the rotation of the sprocket, preventing the chain from sagging due to its own weight. No support structure is needed; the sag is converted into tension on the upper chain, keeping it straight and ensuring a constant gap between the scraper and the base plate, thus avoiding frictional losses. The lower placement of the drive and driven sprockets, combined with an adjustable tension sleeve structure, eliminates energy loss caused by friction in traditional drag chain plates. The combination of a transmission chain with a unidirectional bending limiting structure and an inverted conical guide plate effectively limits the lateral displacement of the scraper during operation, maintaining a constant gap between the scraper and the base plate and preventing rock wool debris from embedding into the scraper gap.

Detailed Implementation

[0024] like Figures 1-4 As shown, this embodiment provides a scraper machine for collecting rock wool, including a frame 1 and a transmission mechanism mounted on the frame 1.

[0025] like Figure 1 As shown, the transmission mechanism includes a drive sprocket 2 located at the tail of the frame 1 and a driven sprocket 3 located at the head of the frame 1. A transmission chain 9 is mounted on the drive sprocket 2 and the driven sprocket 3. A base plate 4 is located in the middle of the frame 1 and is arranged horizontally with the frame 1. The base plate 4 and the transmission chain 9 maintain a certain gap in the vertical direction. A guide plate 5 is also provided on the top of the frame 1. The guide plate 5 has an inverted conical structure and is located on both sides and the end face of the head of the frame 1.

[0026] Specifically, the drive sprocket 2 is located at the bottom of the base plate 4 and is connected to the geared motor 8 via a coupling connected to the drive shaft; the driven sprocket 3 is located at the bottom of the base plate 4 and is connected to the driven shaft; and a double-row roller transmission chain 9 is installed on both sprockets.

[0027] A stamped base plate 4 is provided in the middle of the frame 1, which is horizontally arranged with the frame 1. The base plate 4 and the transmission chain 9 have a certain dynamic gap in the vertical direction, which ensures the smoothness of material conveying and avoids contact friction.

[0028] A tensioning sleeve 7 for adjusting the tension of the transmission chain 9 is provided on one side of the head position of the frame 1. The tensioning sleeve 7 is fixed to the base on both sides of the frame 1 by bolts in a symmetrical distribution. The bolt tail is equipped with an elastic washer to prevent loosening.

[0029] like Figure 2 As shown, the transmission chain 9 consists of an outer link 10 and an inner link 11 that are hinged to each other. An axial baffle 12 is provided on the outer side of the hinge joint between the outer link 10 and the inner link 11, and a roller is provided on the inner side of the inner link 11.

[0030] Specifically, the outer link 10 assembly includes two parallel outer link plates, which are rigidly connected by a press-fit pin; the inner link 11 assembly consists of two inner link plates and a sleeve with an interference fit; the outer link 10 and the inner link 11 are hinged by a clearance fit between the pin and the sleeve, and an axial baffle 12 is fitted on the outside of the hinge. The width of the axial baffle 12 is greater than the horizontal projection area of ​​the hinge part of the inner link 11 and the outer link 10, forming a one-way bending limiting structure.

[0031] The contact interference between the side edge of the axial baffle 12 and the hinge pair effectively limits the bending angle of the hinge pair in the non-working direction. This ensures the normal flexural movement of the chain in the transmission plane, while the physical blocking effect of the baffle creates a mechanical constraint in the perpendicular transmission direction, thus ensuring that the chain link system can only undergo controllable elastic deformation along the preset transmission direction; this avoids abnormal wear and mechanism failure caused by multi-directional bending.

[0032] like Figure 3 As shown, the central axes of both the driving sprocket 2 and the driven sprocket 3 are located below the base plate 4, so that the lower section of the chain is unsupported below the base plate 4 and does not require any additional support device. This avoids friction between the lower chain and the support device, thus preventing increased no-load loss.

[0033] like Figure 2 and Figure 4 As shown, the transmission chain 9 is arranged parallel to both sides of the frame 1, and multiple scrapers 6 arranged in a comb-like pattern are vertically installed between the transmission chains 9; a certain gap is maintained between the scrapers 6 and the base plate 4.

[0034] A continuous working surface is formed along the conveying direction by scrapers 6 arranged in a comb-like pattern. There is an adjustable gap of 3-5mm between the bottom edge of the scraper 6 and the bottom plate 4 of the conveyor. This design ensures material pushing efficiency and avoids wear caused by direct metal friction. The running trajectory of the scraper 6 is always parallel to the plane of the bottom plate 4, and synchronous reciprocating motion is achieved under the drive of the sprocket transmission system.

[0035] The working principle of this utility model:

[0036] The driving sprocket 2 drives the driven sprocket 3 to rotate synchronously via the transmission chain 9, causing the transmission chain 9 to form a continuous closed-loop motion. During equipment operation, the upper part of the transmission chain 9 requires no support and can remain straight on its own, maintaining a constant gap between the scraper 6 and the base plate 4. Combined with the lossless suspended design of the lower half of the chain, this eliminates the sliding friction loss between the chain and its own support or between the scraper 6 and the base plate 4 during the no-load operation of traditional scraper conveyors, achieving frictionless operation with zero contact throughout the transmission path and significantly reducing no-load energy consumption.

[0037] When the raw cotton enters the system, the scraper 6, which moves synchronously with the transmission chain 9, continuously pushes the raw cotton towards the drive sprocket 2 based on its special angle and movement trajectory. When the material is conveyed to the end of the bottom plate 4, the scraper 6 completes a smooth transition along the inclined guide structure of the bottom plate 4, and the material falls precisely into the conveying channel of the inclined scraper 6 through gravity and inertia, forming an efficient and continuous raw cotton conveying operation.

[0038] While the specific embodiments of this disclosure have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this disclosure. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this disclosure are still within the scope of protection of this disclosure.
