[0022] Figure 1 A top perspective view of an embodiment of the blade of the present application.

[0023] The blade of the present application is arranged below the cutting part of the tunneling machine and close to the ground, and is used to collect and transport the materials such as coal and gravel cut down by the tunneling machine. Specifically, the materials cut down by the tunneling machine are collected by the blade and then transported by the blade. Figure 1 As can be seen from the drawings, the blade has a top panel 14, a blade head end 15 and a blade tail end 16, the blade head end 15 of the blade is used to shovel the materials cut down by the tunneling machine to the top panel 14 of the blade, and the blade tail end 16 of the blade is used to be connected to the lower part of the tunneling part of the tunneling machine.

[0024] The top panel 14 of the main blade 1 has a star wheel 11 and a conveying device 12, the star wheel 11 collects and pushes the materials shovelled into the top panel 14 of the blade head end 15 to the conveying device 12, and the conveying device 12 conveys the materials out. In the embodiment shown in the drawings, the conveying device 12 is located at the middle part of the main blade 1, and two star wheels 11 are located at both sides of the conveying device 12, the materials cut down are pushed from both sides of the conveying device 12 to the conveying device 12 for conveying. Figure 1

[0025] ​When the heading machine deviates in the roadway, the two sides of the shovel plate will abut against the roadway wall surface along with the deviation of the heading machine.

[0026] As can be seen from the figure, the shovel plate comprises a main shovel plate 1, a secondary shovel plate 2 and a pressure pump 6 (as shown in Figure 4 The secondary shovel plate 2 has a first side 17 (as shown in Figure 2 ) close to the main shovel plate 1 and a second side 18 away from the main shovel plate 1.

[0027] In the embodiment shown in Figure 1 , two secondary shovel plates 2 are symmetrically arranged on the two sides of the main shovel plate 1, and the two secondary shovel plates 2 are respectively connected to the two sides of the main shovel plate 1 through shafts 10, so that the secondary shovel plates 2 can respectively expand from the two sides of the main shovel plate 1 at an angle with the shaft 10 as the center to the second side 18, so that the entire shovel plate is fan-shaped as shown in Figure 1 , and the secondary shovel plates 2 can also be folded from the two sides of the main shovel plate 1 at an angle with the shaft 10 as the center to the first side 17. When the secondary shovel plates 2 are expanded, the secondary shovel plates 2 can abut against the roadway wall surface of the heading machine, so as to exchange force with the roadway wall surface. In alternative embodiments, the number of secondary shovel plates 2 on the two sides of the main shovel plate 1 is not limited, and multiple symmetric secondary shovel plates 2 can also be arranged.

[0028] The pressure pump 6 can be arranged between the main shovel plate 1 and the secondary shovel plate 2, specifically, the two ends of the pressure pump 6 are respectively connected to the main shovel plate 1 and the secondary shovel plate 2, the pressure pump 6 is used to control the expansion or folding of the secondary shovel plate 2 relative to the main shovel plate 1, and when the secondary shovel plate 2 is expanded to abut against the roadway wall surface, the support force is transmitted to the roadway wall surface through the secondary shovel plate 2, so that the heading machine can be pushed to correct the deviation by the reaction force transmitted back through the roadway wall surface.

[0029] Alternatively, the secondary shovel plate 2 can be embedded inside the two sides of the main shovel plate 1, so that the secondary shovel plate 2 can be expanded or folded inside the main shovel plate 1, so that the secondary shovel plate 2 can maintain the original volume of the shovel plate in the folded state, and the expansion of the secondary shovel plate 2 will not bump into the roadway ground and affect the expansion of the secondary shovel plate 2. Figure 1 The expanded state of the secondary shovel plate 2 is shown in the figure, and the secondary shovel plate 2 can also be folded and embedded inside the two sides of the main shovel plate 1. In other embodiments, the secondary shovel plate 2 can also be arranged at the bottom of the main shovel plate 1.

[0030] According to the embodiment shown in the figure, the top panel 14 of the main shovel plate 1 is inclined towards the bottom of the shovel plate at the shovel head end 15, so that the shovel head end 15 of the main shovel plate 12 is close to the tunnel floor at its bottom to facilitate shoveling materials. Specifically, the top panel 14 of the main shovel plate 1 is provided with a downward inclined plate 13 at the shovel head end 15. The downward inclined plate 13 forms a stable slope between the tunnel floor and the top panel 14 of the main shovel plate 1 to facilitate shoveling the cut materials that fall to the ground and guide them into the top panel 14 of the main shovel plate 1.

[0031] In the embodiment shown in the figure, the auxiliary shovel plate 2 includes a top plate 22 and a baffle plate 23. The top plate 22 has an arc along the shovel head end 15, and the shovel head end 15 of the top plate 22 is inclined to its bottom and close to the bottom ground, smoothly transitioning with the downward inclined plate 13 of the main shovel plate 1. The shovel head end 15 of the top plate 22 facilitates shoveling up ground materials and guiding the materials into the top plate 22 of the shovel plate.

[0032] As shown in the figure, the baffle 23 is set on the edge of the second side 18 of the top plate 22 to prevent the material entering the top plate 22 from falling from the side edge, and when the auxiliary shovel plate 2 is retracted, the baffle 23 can drive the material on the top plate 22 to gather towards the star wheel 11.

[0033] exist Figure 1 In one embodiment, optionally, the secondary shovel plate 2 may also be equipped with a roller 5. The roller 5 is located at the angle between the second side 18 of the secondary shovel plate 2 and the shovel head end 15. When the secondary shovel plate 2 is unfolded, the roller 5 moves away from the main shovel plate 1 and abuts against the tunnel wall. The pressure pump 6 can transmit supporting force to the tunnel wall through the roller 5. The roller 5 can roll along the tunnel wall, thereby reducing the friction between the secondary shovel plate 2 and the tunnel wall, reducing the wear rate of the secondary shovel plate 2, and reducing the wear of the secondary shovel plate 2. Figure 2 This is a perspective view of one embodiment of the auxiliary shovel plate of the present invention; Figure 3 for Figure 2 A bottom-view perspective view of an embodiment of the auxiliary shovel plate.

[0034] It should be noted that the auxiliary shovels 2 on both sides of the main shovel 1 have the same shape and structure and are symmetrically arranged. The following explanation will take the auxiliary shovel 2 on one side of the main shovel as an example.

[0035] Combination Figure 2 and Figure 3 It can be clearly seen that the complete structure of the auxiliary shovel plate 2 is formed by a shell with an internal space 29, which is supported by a surrounding panel. This shell is adapted to be embedded inside the two sides of the main shovel plate 1 and is connected to the top panel 14 of the main shovel plate 1 (as shown in the image). Figure 1 (as shown) and bottom panel 8 (as shown) Figure 5 (As shown) Smooth transition.

[0036] Specifically, the auxiliary shovel plate 2 has a top plate 22, a bottom plate 24, a first side plate 25 located on the first side 17, a second side plate 27 located on the second side 18, and a rear panel 28. The top plate 22, the bottom plate 24, the first side plate 25, the second side plate 27, and the rear panel 28 form an internal space 29 of the auxiliary shovel plate 2.

[0037] The top plate 22, bottom plate 24, first side plate 25, second side plate 27 and rear panel 28 can isolate the interior space 29 from the external environment, thereby protecting the interior space 29 from external dust pollution.

[0038] The internal space 29 of the auxiliary shovel plate 2 opens to the first side 17 for connecting the pressure pump 6 (such as...). Figure 4 As shown), specifically, the first side plate 25 is located on the first side 17 near the head end 15, and the internal space 29 is open to the first side 17 near the tail end 16.

[0039] As can be seen from the figure, the bottom plate 24 and the top plate 22 have the same shape and are arranged opposite each other. The top plate 22 and the bottom plate 24 are narrower at the tail end 16 and gradually transition to a wider shape at the head end 15. The top plate 22 and the bottom plate 24 gradually close at the head end 15, smoothly transitioning with the downward inclined plate 13 of the main shovel plate 1. The head end 15 of the auxiliary shovel plate 2 also plays the role of scooping up the ground material and guiding the material into the top plate 22.

[0040] The top plate 22 and bottom plate 24 can be integrally formed and gradually close at the shovel head end 15. Alternatively, as shown in the figure, the top plate 22 and bottom plate 24 can be respectively connected to the front top plate 21 and the front bottom plate 26 at the shovel head end 15, and the front top plate 21 and the front bottom plate 26 gradually close at the shovel head end 15. The added front top plate 21 and front bottom plate 26 can be flexibly adjusted at the closing angle to adapt to the angle of the downward inclined plate 13 of the shovel head end 15 of different tunneling machines, so as to achieve a better material shoveling effect.

[0041] from Figure 2 It can be seen that the shape of the first side plate 25 changes with the top plate 22 and the bottom plate 24, and its width gradually decreases from the tail end 16 to the head end 15; from Figure 3 It can be seen that the shape of the second side plate 27 also changes with the top plate 22 and the bottom plate 24. Its width gradually decreases from the tail end 16 to the head end 15. Thus, the tail end 16 of the auxiliary shovel plate 2 is higher than its head end 15 and the side is triangular, so that the panels fit together to separate the internal space 29 from the external environment.

[0042] As can be seen from the figures, the auxiliary blade 2 is provided with a shaft sleeve 4, specifically, the shaft sleeve 4 is provided at the intersection of the first side 17 of the top plate 22 and the bottom plate 24 and the shoveling tail end 16, and the rotating shaft notch 41 is adapted to be provided with the shaft sleeve 4. Correspondingly, the main blade 1 is provided with a shaft column 42 (as shown in Figure 4 FIG. 2), and the shaft sleeve 4 is used to be embedded in the shaft column 42 of the main blade 1, forming the shaft connection between the auxiliary blade 2 and the main blade 1, so that the shaft sleeve 4 can rotate around the shaft column 42 as the center.

[0043] As can be seen from the figures, the auxiliary blade 2 also includes a pump shaft 3, which is located in the internal space 29 between the top plate 22 and the bottom plate 24 and is close to the shaft sleeve 4, and the pump shaft 3 is used to connect one end of the pressure pump 6 (as shown in Figure 4 FIG. 2), and the pressure pump 6 can transmit the supporting force through the pump shaft 3.

[0044] As can be clearly seen from the embodiments in the figures, the roller 5 is arranged in the internal space 29 between the top plate 22 and the bottom plate 24 and is located at the corner where the shoveling head end 15 and the shoveling tail end 16 meet, and the roller 5 is half covered by the top plate 22 and the bottom plate 24 of the auxiliary blade 2, part of the roller 5 protrudes from the corner, and the other part is in the internal space 29. The roller 5 arranged in this way can also keep the shell of the auxiliary blade isolated from the internal space 29 and the external environment of the tunnel at the roller 5, thereby preventing external substances from entering the internal space 29 and damaging the equipment and facilities in the internal space 29. Moreover, when the material falls to the roller 5, the material will be blocked by the top plate 22 and guided to the top of the top plate 22, and will not enter the internal space 29 with the roller, thereby further ensuring the isolation of the internal space 29 from the external environment and reducing the damage to the facilities and equipment in the internal space.

[0045] When the auxiliary blade 2 is unfolded, the roller 5 can abut against the tunnel wall surface, and the supporting force transmitted by the pressure pump 6 can be transmitted from the pump shaft 3 to the tunnel wall surface through the roller 5.

[0046] Figure 3 The thick arrow in the figure indicates the reaction force of the roller 5 from the tunnel wall surface to the supporting force of the pressure pump 6. As can be seen from the figure, the reaction force from the wall is decomposed, respectively, extending from the second side 18 to the first side 17 at the shoveling head end 15 and extending along the second side 18 from the shoveling head end 15 to the shoveling tail end 16, thereby dispersing the reaction force to reduce the supporting pressure of the pressure pump 6. It can be known that the structure of the auxiliary blade 2 and the angle of unfolding from the main blade 1 can reduce the stress of the pressure pump 6 during the correction process, thereby reducing the damage of the pressure pump 6 and prolonging the service life of the pressure pump 6. The pressure pump 6 can also be provided with a safety valve, when the pressure pump 6 is overloaded, opening the safety valve can relieve the pressure of the pressure pump 6, thereby further protecting the pressure pump 6 from being damaged due to overload.

[0047] In an optional embodiment, a power source (not shown in the figure) can be provided at the roller 5, which can drive the roller 5 to roll. It can be understood that the wall surface of the roadway is usually uneven, with recesses or corners, etc. When the roller 5 sinks into the uneven part of the wall surface, the power source can be activated to drive the roller 5 to roll so that the roller 5 has a driving force to climb out of the uneven part of the wall surface, thereby accelerating the deviation correction and reducing the wear of the roller and the pressure pump. The power source can be a combination of a motor and a reducer to drive the roller 5 to roll.

[0048] The roller 5 can be welded to the top plate 22 and the bottom plate 24 at the roller shafts in the internal space 29. Alternatively, the roller 5 can be a pair of wheels connected by a shaft and riveted to the top plate 22 and the bottom plate 24 at the roller shafts, thereby facilitating the installation and replacement of the roller 5.

[0049] In response to the size of the recesses or corners of the wall surface of the roadway, rollers 5 of different sizes can be replaced, or the roller 5 can be replaced with a gear to make the roller 5 leave the recesses or corners of the wall surface more quickly and conveniently, thereby enabling the roadheader to continue the tunneling work quickly.

[0050] In combination Figure 2 With Figure 3 As can be clearly seen, the baffle 23 of the auxiliary shovel plate 2 is provided at the edge of the second side 18 of the top plate 22 and close to the shovel tail end 16, and is open at the shovel head end 15 to provide space for the roller 5 to abut against the wall surface of the roadway. The baffle 23 is used to block the cut material located on the top plate 22 to prevent it from falling out of the second side 18.

[0051] Further, in order to make the baffle 23 better block the material, the baffle 23 is also provided with a mounting hole for mounting a raised baffle or leather, as shown in the figure. When the height of the baffle 23 on the top plate 22 is not high enough to block the material, a raised baffle or leather can be mounted on the mounting hole of the baffle 23 by screws, rivets, etc. to increase the height of the baffle 23, thereby better preventing the material from falling out of the second side 18.

[0052] From Figure 3 It can also be seen that the back plate 28 of the auxiliary shovel plate 2 has a hook ring 7 for hoisting and installing the auxiliary shovel plate 2.

[0053] Figure 4 An internal structure diagram of an embodiment of the auxiliary shovel plate of the present application connected with the main shovel plate.

[0054] In combination Figure 1 As can be seen, the top plate 14 and the bottom plate 8 on both sides of the main shovel plate 1 have an internal accommodating space 19, and the auxiliary shovel plate 2 is adapted to be embedded in the accommodating space 19.

[0055] The main blade 1 is provided with a shaft column 42 and a pressure pump 6 near the second side 18. The shaft column 42 is fixedly installed on the main blade 1, and the shaft sleeve 4 of the auxiliary blade 2 is sleeved on the shaft column 42, so that the main blade 1 and the auxiliary blade 2 are connected in the shaft, and the auxiliary blade 2 can rotate around the shaft column 42 as the center.

[0056] The two ends of the pressure pump 6 are connected to the containing space 19 and the internal space 29 respectively, that is, the pressure pump 6 is located inside the main blade 1 and the auxiliary blade 2, so that the shell of the main blade 1 and the auxiliary blade 2 can protect the equipment such as the pressure pump 6 in the containing space 19 and the internal space 29, and prevent the dust in the external environment from affecting the normal work of the equipment such as the pressure pump 6.

[0057] The pressure pump 6 is connected with the pump shaft 3 in the shaft, and specifically, as shown in the figure, the pressure pump 6 has a piston rod 61 and a pump body 62, the pump body 62 is connected with the main blade 1, and the piston rod 61 is connected with the pump shaft 3, so that the auxiliary blade 2 can be pushed by the pump shaft 3 to expand around the shaft column 42 to the second side 18 or to contract to the inside of the main blade 1 away from the second side 18. In the process of correcting deviation, the roller 5 abuts against the wall surface of the roadway, and the pressure pump 6 applies a supporting force against the wall surface of the roadway through the pump shaft 3, so as to achieve the effect of correcting deviation through the reaction force of the wall surface.

[0058] As can be seen from the embodiment in the figure, the pump body 62 of the pressure pump 6 is connected with the main blade 1, and the piston rod 61 of the pressure pump 6 is connected with the pump shaft 3, so that the pressure pump 6 can more conveniently apply pressure to the auxiliary blade 2. In an alternative embodiment, the pump body 62 of the pressure pump 6 can be connected with the pump shaft 3, and the piston rod 61 of the pressure pump 6 can be connected with the main blade 1, as long as the pressure can be applied to the auxiliary blade 2.

[0059] The connection mode of the pressure pump 6 and the pump shaft 3 can be fixed connection or shaft connection. The connection mode of the pressure pump 6 and the main blade 1 can also be fixed connection or shaft connection, and the specific connection mode can be designed according to the actual situation. The shaft connection mode of the pressure pump 6 will be described in detail in the following Figure 5 embodiment.

[0060] Figure 5 It is an embodiment of the internal connection structure of the auxiliary blade and the main blade at the tail end of the blade.

[0061] As can be clearly seen from the embodiment Figure 5 , the shaft sleeve 4 can also have a bottom support 45 and a pressing plug 44, the bottom support 45 is used to be sleeved on the bottom of the shaft column 42 to support the shaft sleeve 4, and the pressing plug 44 is used to be sleeved on the top of the shaft column 42 to press and fix the shaft sleeve 4, so that the shaft sleeve 4 is axially fixed and more stable in the axial direction.

[0062] Further, as can be seen from the figure, the plug 44 is a truncated cone with a top end diameter larger than a bottom end diameter, and the top end edge of the shaft sleeve 4 is provided with a partial side wall 43, which has an inclined surface to match the side surface inclined surface shape of the truncated cone of the plug 44 to be embedded in the pressing, and the top surface of the side wall 43 is flush with the top surface of the plug 44, so that the plug 44 can compact the shaft sleeve 4 towards the bottom support 45, thereby preventing it from falling off from the top during rotation.

[0063] As can also be seen from the figure, a notch is provided at the top end of the shaft column 42, which is used to set the shaft column gland 46, which is used to fix the top panel 14 to the plug 44 from the top of the top panel 14, so that the top panel 14 presses the plug 44, and the fixing method can be but not limited to pin shaft fixing, welding, bolt fixing, riveting, etc.

[0064] Further, in order to adapt to different diameter shaft columns 42, the top end and the bottom end of the internal pipeline of the shaft sleeve 4 can also be respectively provided with a sleeve ring (not shown in the figure), which makes the internal pipeline of the shaft sleeve 4 closer to the shaft column 42, so that the shaft sleeve 4 can more stably rotate with the shaft column 42 as the center.

[0065] From Figure 5 As can also be seen, the pressure pump 6 is connected with the shaft of the main shovel plate 1 and the auxiliary shovel plate 2 respectively, and the main shovel plate 1 is provided with a mounting shaft near the auxiliary shovel plate 2, which is used to be connected with the shaft of the pressure pump 6.

[0066] Specifically, one end of the pressure pump 6 is provided with a first sleeve ring 63, which is used to be sleeved on the pump shaft 3 of the auxiliary shovel plate 2 and can rotate with the pump shaft 3 as the center. Optionally, as shown in the figure, the top end and the bottom end of the pump shaft 3 are respectively sleeved with a bottom limiting sleeve 32 and a top limiting sleeve 33, which limit the first sleeve ring 63 to the middle segment of the pump shaft 3, so that the piston rod 61 is level with the pump body 62, and the pump shaft gland 34 is fixed to the top plate 22, so that the support force transmitted by the pressure pump 6 will not deviate towards the top or the bottom.

[0067] The other end of the pressure pump 6 can also be provided with a second sleeve ring 64, which is used to be sleeved on the mounting shaft of the main shovel plate 1, and the pressure pump 6 can also rotate with the shaft of the main shovel plate 1 as the center, so that the auxiliary shovel plate 2 can have a larger angle of rotation, and the pressure pump 6 can have more flexibility when correcting deviation, and can adjust the angle according to the support pressure, so that the support force output by the pressure pump 6 can better act on the roadway wall surface through the auxiliary shovel plate 2, thereby completing the deviation correction.

[0068] The application further provides a tunneling machine comprising the aforementioned shovel plate, and thus has the respective features of the shovel plate in the aforementioned embodiments, and thus has the corresponding advantages.

[0069] It should be noted that the shovel plate of the application can be used for individual deviation correction or can assist other deviation correction systems to correct deviation.

[0070] The technical scope of the application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the application, and these modifications and changes should be within the scope of the application.
