[0002] In recent years, with the development and progress of society, higher requirements have been put forward for the construction safety and environmental protection of mining equipment. Therefore, tunnel boring machines using non-blasting mining methods have been widely used in fields such as coal mines and tunnels. At present, the material transportation device of the tunnel boring machine usually includes a scraper conveyor and a belt conveyor. When the tunnel boring machine is working, the cut material is first transported to the scraper conveyor through the star wheel on the loading device, and then the sprocket on the drive assembly in the scraper conveyor rotates, driving the scraper chain to rotate, so as to transfer the material to the belt conveyor. The belt in the belt conveyor rotates to transport the material to the transfer vehicle, and finally the material is transported by the transfer vehicle. However, during the operation of the scraper conveyor, the scraper chain is easily stuck in the groove of the sprocket, and the machine needs to be shut down for maintenance, resulting in low movement smoothness and low transportation efficiency.

[0003] For example, Chinese utility model patent CN20630608U discloses an anti-chain jamming structure for the first conveyor of a tunnel boring machine. Although it can prevent the chain jamming phenomenon when the scraper chain assembly rotates in the reverse direction, it still has the above-mentioned shortcomings. Utility Model Content

[0008] Furthermore, the scraper conveyor also includes a wear-resistant component, which includes a first wear-resistant plate arranged in the transport trough component and supporting the scraper chain, and a second wear-resistant plate connected to the sliding mounting seat, and the first wear-resistant plate and the second wear-resistant plate are matched in a concave and convex manner.

[0009] Furthermore, the concave and convex matching surfaces between the first wear-resistant plate and the second wear-resistant plate are arranged in a V shape.

[0010] Furthermore, the scraper chain includes a slewing chain rotatably arranged in the transport trough assembly and connected to the transmission sprocket, and a scraper plate connected to the slewing chain. There are multiple scraper plates, and the multiple scraper plates are arranged at intervals along the rotation direction of the slewing chain. The scraper plates are arranged obliquely along the material conveying direction.

[0011] Furthermore, the scraper conveyor also includes a chain presser, which includes a mounting plate connected to the transport trough assembly, a limiting plate connected to the mounting plate and vertically abutting the slewing chain, and a reinforcing rib plate respectively connected to the mounting plate and the limiting plate.

[0017] The scraper conveyor of the utility model has a conveying trough assembly connected to the loading trough of the excavator to receive the materials generated during the working process of the excavator, and then drives the scraper chain to rotate through the driving assembly to transport the materials. During the working process of the scraper conveyor, the driving assembly can be driven to slide by the tensioning assembly to adjust the slack of the scraper chain, thereby improving the stability and reliability of the scraper chain during movement. The driving assembly is installed with a driving member, a transmission sprocket and a chain de-clipper through a sliding mounting seat, and the sliding mounting seat is driven by the tensioning assembly to slide relative to the conveying trough assembly to adjust the slack of the scraper chain. The driving member drives the transmission sprocket to rotate, thereby driving the scraper chain to rotate and transport materials. At the same time, the chain de-clipper is engaged in the groove of the transmission sprocket to fundamentally avoid the scraper chain from circumferentially rotating relative to the transmission sprocket, thereby preventing the scraper chain from being stuck in the groove of the transmission sprocket, thereby improving the movement stability and transportation efficiency of the scraper chain.

[0033] like Figure 1 、 Figure 2 and Figure 5 As shown, the scraper conveyor of this embodiment includes a transport trough assembly 100, a scraper chain 200 rotatably arranged in the transport trough assembly 100, a drive assembly 300 slidably arranged on the transport trough assembly 100 and connected to the scraper chain 200, and a tensioning assembly 400 arranged on the transport trough assembly 100 and connected to the drive assembly 300 for driving the drive assembly 300 to slide to adjust the slackness of the scraper chain 200; the drive assembly 300 includes a sliding mounting seat 310 slidably arranged on the transport trough assembly 100 and connected to the tensioning assembly 400, a driving member 320 arranged on the sliding mounting seat 310, a transmission sprocket 330 connected to the output end of the driving member 320 and connected to the scraper chain 200, and a chain decoupler 340 arranged on the sliding mounting seat 310 and stuck in the groove of the drive sprocket 330 for preventing the scraper chain 200 from being stuck in the groove of the drive sprocket 330. It should be understood that the groove of the transmission sprocket 330 is a groove portion between two adjacent teeth in the axial direction of the transmission sprocket 330 .

[0034] like Figure 1 、 Figure 2 and Figure 5 As shown, in the scraper conveyor of this embodiment, the transport trough assembly 100 is connected to the loading trough of the tunnel boring machine to receive the materials generated during the operation of the tunnel boring machine, and then the scraper chain 200 is driven to rotate by the drive assembly 300 to transport the materials. During the operation of the scraper conveyor, the drive assembly 300 can be driven to slide by the tensioning assembly 400 to adjust the slackness of the scraper chain 200, thereby improving the stability and reliability of the scraper chain 200 during movement. The drive assembly 300 is installed with the driving member 320, the transmission sprocket 330 and the chain releaser 340 through the sliding mounting seat 310, and the sliding mounting seat 310 is driven by the tensioning assembly 400 to slide relative to the transport trough assembly 100 to adjust the scraper chain 200. The slackness of the plate chain 200 is driven by the driving member 320 to drive the transmission sprocket 330 to rotate, thereby driving the scraper chain 200 to rotate and transport materials. At the same time, the chain decoupler 340 is stuck in the groove of the transmission sprocket 330 to fundamentally prevent the scraper chain 200 from rotating circumferentially relative to the transmission sprocket 330, and then prevent the scraper chain 200 from being stuck in the groove of the transmission sprocket 330, thereby improving the movement stability and transportation efficiency of the scraper chain 200. Compared with the existing technology, this solution fundamentally eliminates the chain sticking phenomenon of the scraper chain 200 being stuck in the groove of the transmission sprocket 330, improves the movement stability and transportation efficiency of the scraper chain 200, is highly practical, and is suitable for wide promotion and application.

[0035] like Figure 1As shown, the transport trough assembly 100 optionally includes a front trough 110, a middle trough 120, and a tail trough 130. The front trough 110 is used to connect to the loading trough on the loading device of the roadheader to transfer materials from the loading device to the scraper conveyor. The rear end of the front trough 110 is connected and fixed to the middle trough 120 via a connecting block 140 and a pin 150. The rear end of the middle trough 120 is connected and fixed to the tail trough 130 via a flange plate 160 and a screw 170. Each component is detachably connected to facilitate the installation and removal of various components of the scraper conveyor, improving the installation and maintenance efficiency of the scraper conveyor while ensuring the operating efficiency of the scraper conveyor. Optionally, in another embodiment, the transport trough assembly 100 can also add a transport trough between the middle trough 120 and the tail trough 130 to change the horizontal position and vertical height of the output end of the tail trough 130, thereby meeting the unloading requirements in different occasions, and has strong applicability. Optionally, in one embodiment, the transport chute assembly 100 further includes a support cylinder 180 arranged to support the tail chute 130 from the bottom, tilting the tail chute 130 upward. The support cylinder 180 adjusts the tilt of the tail chute 130, thereby changing the horizontal position and vertical height of the output end of the tail chute 130. Optionally, a drive assembly 300 and a tensioning assembly 400 are arranged on the tail chute 130, and materials are output via a drive sprocket 330 on the drive assembly 300.

[0036] like Figure 2 and Figure 3 As shown, optionally, the tensioning assembly 400 includes a cylinder seat 410 arranged on the tail groove 130, a sliding groove opened on the tail groove 130 and accommodating the sliding mounting seat 310, guide blocks 430 arranged on both sides of the sliding groove for limiting and guiding the sliding mounting seat 310, a tensioning cylinder 420 connected to the cylinder seat 410 and the sliding mounting seat 310 respectively for driving the sliding mounting seat 310 to slide in the sliding groove, and a limiting portion 440 arranged on the end of the sliding groove facing away from the cylinder seat 410 for preventing the sliding mounting seat 310 from falling out. Through the extension and contraction of the tensioning cylinder 420, the sliding mounting seat 310 slides in the sliding groove along the guide block 430 to adjust the position of the driving member 320 and the transmission sprocket 330, thereby adjusting the slackness of the scraper chain 200, and the sliding mounting seat 310 is prevented from falling out by the limiting portion 440, thereby ensuring that the movement of the driving assembly 300 is within a safe range. Optionally, two tensioning assemblies 400 are provided, and the two tensioning assemblies 400 are arranged on opposite sides of the transport trough assembly 100 to drive the two ends of the driving assembly 300 to move synchronously. Optionally, the driving member 320 includes a driving motor and a reducer, the output end of the driving motor is connected to the reducer, and the output end of the reducer is connected to the transmission sprocket 330.

[0037] like Figure 5 and Figure 7As shown, in this embodiment, the chain remover 340 includes a connecting plate 341 connected to the sliding mounting base 310 and a chain removal plate 342 connected to the connecting plate 341. The chain removal plate 342 is arranged in an arc shape at the end facing the drive sprocket 330 and engages with the groove of the drive sprocket 330. Specifically, the connecting plate 341 is connected to the sliding mounting base 310, and the chain removal plate 342 is connected to the connecting plate 341. The chain removal plate 342 is arranged in an arc shape at the end facing the drive sprocket 330 and engages with the groove of the drive sprocket 330, preventing the scraper chain 200 from getting stuck in the groove of the drive sprocket 330. This reduces sudden and violent shaking of the scraper chain 200 during transmission, and the occurrence of chain jamming and chain jumping, thereby improving the smooth operation of the scraper conveyor. Optionally, a predetermined distance is maintained between the chain removal plate 342 and the drive sprocket 330 to prevent the chain removal plate 342 from obstructing the operation of the drive sprocket 330.

[0038] like Figure 1 and Figure 4 As shown, in this embodiment, the scraper conveyor further includes a wear-resistant assembly 500, which includes a first wear-resistant plate 510 arranged in the transport trough assembly 100 and supporting the scraper chain 200, and a second wear-resistant plate 520 connected to the sliding mounting seat 310. The first wear-resistant plate 510 and the second wear-resistant plate 520 are matched with each other in a concave-convex manner. Specifically, the first wear-resistant plate 510 supports the scraper chain 200, and the second wear-resistant plate 520 is connected to the sliding mounting seat 310 to reduce the wear of the scraper chain 200 on the transport trough assembly 100 during operation. It should be understood that when the tensioning assembly 400 drives the sliding mounting seat 310 to slide, the second wear-resistant plate 520 slides synchronously with the sliding mounting seat 310, and an opening and closing gap may be generated between the first wear-resistant plate 510 and the second wear-resistant plate 520. The concave and convex matching of the first wear-resistant plate 510 and the second wear-resistant plate 520 can ensure the smooth operation of the scraper chain 200 on the first wear-resistant plate 510 and the second wear-resistant plate 520 to the greatest extent, and avoid the scraper chain 200 from falling into the opening and closing gap after the first wear-resistant plate 510 and the second wear-resistant plate 520 are separated, so that the scraper chain 200 runs smoothly.

[0039] like Figure 4 As shown, in this embodiment, the concave-convex mating surface between the first wear-resistant plate 510 and the second wear-resistant plate 520 is arranged in a V-shape. Specifically, the first wear-resistant plate 510 and the second wear-resistant plate 520 are mated together via the V-shaped concave-convex mating surface to maximize the ability of the scraper chain 200 to operate on the first wear-resistant plate 510 and the second wear-resistant plate 520, and to prevent the scraper chain 200 from getting stuck in the opening and closing gap between the first wear-resistant plate 510 and the second wear-resistant plate 520, thereby ensuring smooth operation of the scraper chain 200. Optionally, in another embodiment, the concave-convex mating surface between the first wear-resistant plate 510 and the second wear-resistant plate 520 is arranged in an arc shape.

[0040] like Figure 6 As shown, in this embodiment, the scraper chain 200 includes a rotary chain 210 rotatably arranged in the transport trough assembly 100 and connected to the drive sprocket 330, and a scraper plate 220 connected to the rotary chain 210. There are multiple scraper plates 220, and the multiple scraper plates 220 are arranged at intervals along the rotation direction of the rotary chain 210. The scraper plates 220 are arranged obliquely along the material conveying direction. Specifically, the rotary chain 210 is connected to the transmission sprocket 330, and the transmission sprocket 330 rotates to drive the rotary chain 210 to rotate, and then drives multiple scraper plates 220 to move synchronously, thereby transporting materials. Moreover, since the scraper plates 220 are arranged obliquely along the material conveying direction, a large amount of material is prevented from accumulating in front of a single scraper plate 220, ensuring that multiple scrapers convey materials evenly, and preventing a large amount of material from accumulating and jamming the scraper chain 200, thereby damaging the driving member 320. Moreover, when the scraper plate 220 moves, the component force of the material's own weight on the inclined surface of the scraper plate 220 can also press the scraper plate 220, thereby avoiding the shaking of the rotary chain 210 during the transmission process and improving the stability of the scraper chain 200 during movement.

[0041] like Figure 8 As shown, in this embodiment, the scraper conveyor further includes a chain press 600. The chain press 600 includes a mounting plate 610 connected to the transport trough assembly 100, a stop plate 620 connected to the mounting plate 610 and vertically abutting the slewing chain 210, and a reinforcing rib plate 630 respectively connected to the mounting plate 610 and the stop plate 620. Specifically, the stop plate 620 is mounted on the mounting plate 610, and then connected to the mounting plate 610 and the stop plate 620 via respective rib plates to ensure the overall structural strength of the chain press 600. The stop plate 620 vertically abuts the slewing chain 210 to prevent the scraper chain 200 from disengaging, limit the amplitude of the slewing chain 210's runout, and prevent debris or rocks from falling into the slewing chain 210, causing the chain to become uncoupled. It should be understood that the chain press 600 is arranged above the slewing chain 210 to vertically abut the slewing chain 210.

[0042] like Figure 9 As shown, in this embodiment, the end of the limit plate 620 is bent upward at an angle to form an arc. Specifically, the arc prevents debris and rocks from falling into and getting stuck in the drive sprocket 330, thereby preventing the chain from becoming uncoupled. Alternatively, in another embodiment, the limit plate 620 is arranged straight. It should be understood that the shape of the limit plate 620 in the material conveying direction can be customized as needed.

[0043] like Figure 1As shown, in this embodiment, multiple chain pressers 600 are provided, spaced apart within the transport trough assembly 100 along the material conveying direction. Specifically, the multiple chain pressers 600 limit the position of the slewing chain 210 in different areas, thereby maximizing the smooth movement of the slewing chain 210. Optionally, in one embodiment, chain pressers 600 are uniformly distributed within the front trough 110, the middle trough 120, and the rear trough 130.

[0044] like Figure 2 As shown, optionally, in one embodiment, the chain decoupler 340 and the chain presser 600 work together to prevent the scraper chain 200 from jumping and getting stuck during transmission to the greatest extent. The structure is simple and applicable, and the effect is significant.

[0045] like Figure 2 As shown, in this embodiment, the scraper conveyor further includes a flow guide 700 disposed at the output end of the transport trough assembly 100. Specifically, the flow guide 700 guides the material to effectively reduce splashing during material transfer, ensuring smooth transfer of the material to subsequent transport equipment. Optionally, the flow guide 700 is made of rubber. Optionally, the flow guide 700 includes three deflector plates disposed on opposite sides and the bottom of the output end of the transport trough assembly 100.

[0046] The tunnel boring machine of this embodiment includes the above-mentioned scraper conveyor. Specifically, by adopting the above-mentioned scraper conveyor in the tunnel boring machine to realize the transfer and transportation of materials, the transportation stability and efficiency can be greatly improved, the practicality is strong, and it is suitable for wide promotion and application.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
