Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment, and in particular to a scraper conveyor. Background Technology

[0002] Scraper conveyors, widely used in mining, coal mining, and other material handling industries, consist primarily of a drive unit, chain, scrapers, and a central trough. Traditionally, the central trough of scraper conveyors is made of metal (such as steel) to ensure sufficient mechanical strength and wear resistance, adapting to harsh working environments. However, the metal material results in a heavier overall weight for the central trough, increasing the conveyor's load and hindering installation and maintenance. Especially in humid or chemically-containing environments, the metal central trough is susceptible to corrosion, reducing its service life and increasing maintenance frequency. Furthermore, metal central troughs also suffer from high noise levels and high manufacturing costs. Utility Model Content

[0003] This solution addresses the problems and needs raised above by proposing a scraper conveyor that achieves the aforementioned technical objectives and brings about several other technical benefits due to the adoption of the following technical features.

[0004] This utility model proposes a scraper conveyor, including a head, a transition trough, a body, and a tail, which are connected sequentially. The body includes at least one set of scraper chains, which are sleeved on the outside of the head, transition trough, body, and tail along the extension direction of the scraper conveyor.

[0005] The feature is that the fuselage further includes:

[0006] Multiple central slots are arranged sequentially and connected along the extension direction of the fuselage, wherein the central slot at the front end is connected to the transition slot, and the central slot at the rear end is connected to the tail section; the central slots are either split-type or integral-type structures.

[0007] Multiple scrapers are spaced apart along the outer wall of the integral structure formed by the machine head, transition groove, machine body and machine tail, and are fixedly connected to the scraper chain;

[0008] The central groove and the scraper are both made of flame-retardant and anti-static non-metallic materials.

[0009] In this technical solution, a drive unit on the machine head drives the scraper chain to rotate, which in turn drives the scrapers connected to it to rotate, thereby transporting the material located between the two scrapers from one end of the scraper conveyor to the other. Firstly, because the central trough and scrapers of this scraper conveyor are made of flame-retardant and anti-static non-metallic materials, the overall weight of the scraper conveyor is reduced, energy consumption is decreased, and transportation efficiency is improved. Secondly, by using the high-polymer wear-resistant material in this technical solution, the required power of the drive unit can be effectively reduced when transporting the same amount of live material per unit time and length. Thirdly, compared with existing technologies, this technical solution improves installation and transportation convenience and reduces labor costs. Existing steel central troughs typically weigh around 150 kg, while the density of flame-retardant and antistatic non-metallic materials differs from steel by several times. This means that using the central trough of this technical solution will significantly improve the efficiency of workers in transporting, assembling, and disassembling scraper conveyors, reducing labor intensity and providing antistatic properties. Furthermore, it offers excellent corrosion resistance: flame-retardant and antistatic non-metallic materials possess superior chemical stability and corrosion resistance, extending equipment lifespan. Next, it reduces noise: the contact noise between flame-retardant and antistatic non-metallic materials is lower, providing a quieter operating environment. Then, it offers excellent thermal insulation: good thermal insulation properties reduce unnecessary heat loss. Finally, it is cost-effective: flame-retardant and antistatic non-metallic materials are low-cost and easy to form and process, reducing manufacturing difficulty and costs.

[0010] In addition, the scraper conveyor according to this utility model may also have the following technical features:

[0011] In one example of this utility model, the split-type central groove includes:

[0012] Middle section;

[0013] The grooves are detachably connected to both sides of the central plate 110, wherein each central plate is connected to four grooves, and the four grooves are symmetrically arranged in the transverse and thickness directions of the central plate.

[0014] In one example of the invention, the groove includes:

[0015] Support section;

[0016] The connecting part and the extension part are respectively provided on both ends of the support part and extend in a direction away from each other; wherein, the connecting part is connected to the middle plate, and the extension part extends in the lateral direction to the groove (120) that is symmetrical to it.

[0017] In one example of the invention, the groove further includes:

[0018] A reinforcing part is provided at the first connection between the connecting part and the supporting part, and extends in the lateral direction away from the connecting part.

[0019] In one example of this utility model,

[0020] The groove side and the middle plate are connected by fasteners. A plurality of first positioning holes are provided at intervals along the extension direction of the groove side, and second positioning holes corresponding to the first positioning holes are provided at intervals along the extension direction of the middle plate. The fasteners pass through the first positioning holes and the second positioning holes in sequence.

[0021] In one example of this utility model, in the plurality of central grooves, the first connecting gaps of two adjacent central plates and the second connecting gaps of two adjacent groove sides are staggered from each other in the thickness direction.

[0022] In one example of this utility model, the integral central groove includes:

[0023] Middle section;

[0024] The groove is integrally formed on both sides of the middle plate, and the middle plate is connected to the groove near the middle in the thickness direction; wherein, a through hole is provided at the second connection between the middle plate and the groove along the extension direction of the middle groove, configured to connect two adjacent middle grooves.

[0025] In one example of this utility model, the through hole has a circular or polygonal shape.

[0026] In one example of this utility model, a connecting plate is also included, located at the lower end of the groove and connecting two symmetrically arranged grooves.

[0027] In one example of this utility model, a groove is formed on one of the groove side and the connecting plate, and a slider adapted to the groove is formed on the other.

The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model.

[0083] This utility model proposes a scraper conveyor 10, such as Figure 1 and Figure 2 As shown, it includes a head unit 3, a transition groove 2, a body 1, and a tail unit 4, which are connected sequentially. The body 1 includes:

[0084] At least one set of scraper chains 200 are sleeved on the outside of the head 3, transition groove 2, body 1 and tail 4 along the extension direction X of the scraper conveyor 10;

[0085] Multiple central slots 100 are arranged sequentially and connected along the extension direction X of the fuselage 1, wherein the central slot 100 at the front end is connected to the transition slot 2, and the central slot 100 at the rear end is connected to the tail 4; the central slot 100 is a split structure or an integral structure.

[0086] Multiple scrapers 300 are spaced along the outer wall of the integral structure formed by the machine head 3, transition groove 2, machine body 1 and machine tail 4, and are fixedly connected to the scraper chain 200.

[0087] The central groove 100 and the scraper 300 are both made of flame-retardant and anti-static non-metallic materials.

[0088] For example, the scraper chain 200 includes two chains, which are disposed on both sides of the scraper conveyor 1 in the width direction;

[0089] For example, pivotable shafts 5 are respectively provided on the head 3 and the tail 4. Each shaft 5 has two rotating grooves 51. Two scraper chains 200 are respectively fitted into the rotating grooves 51 of the shaft 5 of the head 3 and the rotating grooves 51 of the shaft 5 of the tail 4, and the two scraper chains 200 are fixedly connected by a connector 52.

[0090] For example, the machine head 3 includes a drive device and a reducer. The output shaft of the drive device is connected to the input end of the reducer, and the output end of the reducer is fixedly connected to the rotating shaft of the machine head 2. The drive device drives the rotating shaft to rotate, thereby driving two interconnected scraper chains 200 to rotate synchronously and periodically along the outer side of the machine head 3, transition groove 2, machine body 1 and machine tail 4.

[0091] For example, the drive device may include either a hydraulic motor or a permanent magnet variable frequency motor.

[0092] The specific working process is as follows: The drive device on the machine head 3 drives the scraper chain 200 to rotate, and the scraper chain 200 drives the scraper 300 connected to it to rotate, thereby transporting the material located between the two scraper 300 from one end of the scraper conveyor 10 to the other end. First, because the middle trough 100 and scraper 300 of the scraper conveyor 10 are made of flame-retardant and anti-static non-metallic materials, the overall weight of the scraper conveyor is reduced, energy consumption is reduced, and transportation efficiency is improved. After using the flame-retardant and anti-static non-metallic materials in this technical solution, the scraper conveyor can effectively reduce the required power of the drive device when transporting the same amount of live goods per unit time and length. Second, compared with the prior art, this technical solution improves the convenience of installation and transportation and reduces labor costs. The existing steel central trough 100 typically weighs around 150kg, while the density of flame-retardant and antistatic non-metallic materials differs from that of steel by several times. This means that when using the central trough 100 of this technical solution, the efficiency of workers in transporting, assembling, and disassembling scraper conveyors will be multiplied, reducing the labor intensity of workers and providing antistatic properties. Furthermore, it has good corrosion resistance: flame-retardant and antistatic non-metallic materials have excellent chemical stability and corrosion resistance, which can extend the equipment's lifespan. Next, it has low noise: the contact noise between flame-retardant and antistatic non-metallic materials is relatively low, providing a quieter operating environment. Then, it has good thermal insulation performance: good thermal insulation characteristics reduce unnecessary heat loss. Finally, it is cost-effective: flame-retardant and antistatic non-metallic materials have low cost and are easy to form and process, reducing manufacturing difficulty and costs.

[0093] In one example of this utility model, such as Figures 3 to 7 As shown, the split-type central groove 100 includes:

[0094] Middle plate 110;

[0095] The grooves 120 are detachably connected to both sides of the middle plate 110, wherein each middle plate 110 is connected to four grooves 120, and the four grooves 120 are symmetrically arranged in the lateral direction Z and the thickness direction Y of the middle plate 110 respectively.

[0096] By designing the sidewall 120 and the central groove 100 as detachable structures, assembly and transportation can be facilitated, the space occupied by the central groove 100 during transportation can be simplified, and processing can be made more convenient.

[0097] In one example of the present invention, the groove 120 includes:

[0098] Support part 121;

[0099] The connecting part 122 and the extension part 123 are respectively provided on both ends of the support part 121 and extend in a direction away from each other; wherein, the connecting part 122 is connected to the middle plate, and the extension part 123 extends in the transverse direction Z towards the groove 120 symmetrical to it.

[0100] By providing the connecting part 122, the connecting part 122 can be easily fixed to the middle plate. By providing the support part 121 and the extension part 123, the trough structure for transporting materials can be defined together with the support part 121 and the extension part 123 arranged symmetrically thereto.

[0101] In one example of the present invention, the groove 120 further includes:

[0102] A reinforcing part 124 is provided at the first connection 150 between the connecting part 122 and the supporting part 121, and extends in the lateral direction Z in a direction away from the connecting part 122.

[0103] By setting the reinforcing part 124, the overall structural strength of the groove side 120 can be improved, making the connection between the groove side 120 and the middle plate more reliable.

[0104] Preferably, the cross-section of the reinforcing part 124 is a triangular structure.

[0105] In one example of this utility model,

[0106] The groove 120 and the middle plate 110 are connected by fasteners 130. A plurality of first positioning holes are provided at intervals along the extension direction X of the groove 120, and second positioning holes corresponding to the first positioning holes are provided at intervals along the extension direction X of the middle plate 110. The fasteners 130 pass through the first positioning holes and the second positioning holes in sequence.

[0107] By setting fastener 130, the connection between the groove side 120 and the middle plate 110 can be made more reliable and easier to disassemble and assemble; of course, this utility model is not limited to this, the groove side 120 and the middle plate 110 can also be connected by riveting or welding.

[0108] In one example of this utility model, such as Figure 7 As shown, in the plurality of central grooves 100, the first connecting gap A of two adjacent central plates 110 and the second connecting gap B of two adjacent groove sides 120 are staggered from each other in the thickness direction X.

[0109] In other words, the connection gap between two adjacent middle plates 110 and the connection gap between the groove side 120 do not coincide in the thickness direction Y, which allows multiple middle grooves 100 to be effectively connected into a whole.

[0110] It is understandable that the connection method of two adjacent middle slots 100 is as follows: a first connecting hole 111 is opened on the middle plate 110 of the previous middle slot, and a second connecting hole 126 corresponding to the first connecting hole 111 is opened on the connecting part 122 of the slot side 120 of the next middle slot 100, and the first connecting hole 111 and the second connecting hole 126 are connected by bolts.

[0111] In one example of this utility model, such as Figures 8 to 10 As shown, the integral central groove 100 includes:

[0112] Middle plate 110;

[0113] The groove side 120 is integrally formed on both sides of the middle plate 110, and the middle plate 110 is connected to the groove side 120 at a position near the middle in the thickness direction YH; wherein, the second connection 160 between the middle plate 110 and the groove side 120 is provided with a through hole 161 extending along the X direction of the middle groove 100, configured to connect two adjacent middle grooves 100.

[0114] For example, the channel 120 is formed by die casting in one piece;

[0115] The one-piece molding method results in high structural strength and avoids the trouble of subsequent assembly. When two adjacent central grooves 100 are connected, they are connected through through holes 161 opened on the central grooves 100.

[0116] In one example of this utility model, the through hole 161 has a circular or polygonal shape.

[0117] For example, polygons can be triangles, quadrilaterals, pentagons, etc.

[0118] The circular or polygonal through holes 161 are easy to process and have reliable connections.

[0119] In one example of this utility model, it further includes: a connecting plate 140, located at the lower end of the groove 120, and connecting two symmetrically arranged grooves 120;

[0120] By setting a connecting plate 140 at the lower end of the trough side 120, it is possible to prevent debris from entering the upper end of the middle plate 110 from the lower end of the scraper conveyor 10 during the operation of the middle trough 100, and it can also improve the overall structural strength of the middle trough 100.

[0121] In one example of this utility model, a groove 125 is provided on one of the groove side 120 and the connecting plate 140, and a slider 141 adapted to the groove 125 is formed on the other.

[0122] For example, such as Figure 6 , Figure 7 As shown, sliding grooves 125 are respectively provided on the opposite end faces of the two grooves 120, and sliders 141 are respectively formed on both ends of the connecting plate 140, and the sliders 141 are adapted to the sliding grooves 125.

[0123] For example, sliders 141 are respectively provided on the opposite end faces of the two grooves 120, and grooves 125 are respectively formed on both ends of the connecting plate 140, and the sliders 141 are adapted to the grooves 125.

[0124] The above structure facilitates the connection between the connecting plate 140 and the groove 120, and it can also be used by removing the middle groove 100 of the connecting plate 140.

[0125] In one example of this utility model, the machine head 3 can be selected as a split machine head frame 31 or an integral machine head frame 32, depending on the central slot used, such as... Figure 11 and Figure 12 As shown, the split-type machine head frame 31 has a connecting plate 311 with a through hole 3111. The split-type machine head frame 31 is connected to the split-type central groove 100 by bolts through the through hole 3111 on the split-type machine head 31 and the empty threaded hole on the Z-shaped groove side 120 of the split-type central groove 100. The integral machine head frame 32 has two cylindrical joints 321 with threaded holes, such as... Figure 13 and Figure 14 As shown, the connection method between the integral machine head frame 32 and the integral central groove 100 is as follows: the two cylindrical connectors 321 on the integral machine head frame 32 are respectively inserted into the cylindrical through holes on the integral central groove 100 to be connected, and the cylindrical connectors 321 and the integral central groove 100 are fixed with self-tapping screws.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this utility model, and various combinations can be made to the various technical features and structures proposed by this utility model without exceeding the protection scope of this utility model, which is determined by the appended claims.
