They are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0021] In the description of this disclosure, "multiple" means at least two, such as two, three or more, unless otherwise expressly and specifically limited.

[0022] Figure 1 This is a side view schematic diagram of an embodiment of the integrated cutting and slag removal device of the present invention.

[0023] The integrated cutting and discharging device is the cutting arm of the equipment, used to cut the vertical shaft mining face while transporting the cut-off slag. The equipment is a device with cutting function, including but not limited to vertical shaft tunneling machines, tunneling machines, coal mining machines, etc. As can be seen from the figure, the integrated cutting and discharging device includes a support arm 1, a scraper conveyor 2, and a cutting head 3.

[0024] The support arm 1 is used to connect to the equipment body. The support arm 1 has an end 14, a top 15, an upper side 17, and a lower side 18. The support arm 1 is capable of swinging so that its end 14 can swing to the mining face 16. A cutting head 3 is installed on the end 14. When the end 14 of the support arm 1 swings to the mining face 16, the cutting head 3 can cut the mining face 16. Specifically, the cutting head 3 has a slag guide plate 33 (e.g., ...). Figure 2 As shown, the slag guide plate 33 is used to guide the direction of the cut rock debris.

[0025] The scraper conveyor 2 is arranged along the contour of the support arm 1, that is, the conveyor belt of the scraper conveyor 2 surrounds the contour of the support arm, and the conveyor belt has scrapers 21, which are used to carry the cut rock debris.

[0026] As shown by the arrow in the figure, the conveyor belt moves around the outline of the support arm 1. Specifically, the conveyor belt located on the upper side 17 moves towards the top 15 to transport the rock cuttings upward. Then, the conveyor belt turns around the top 15, moves to the lower side 18 towards the end 14, and turns around the end 14 again towards the top 15, thus running around the support arm 1.

[0027] The rotation direction of the cutting head 3 is as shown by the arrow in the figure, which is consistent with the circumferential running direction of the scraper conveyor 2. Thus, the slag guide plate 33 of the cutting head 3 guides the cut rock cuttings into the scraper 21 of the scraper conveyor 2, and the scraper conveyor 2 transports them out of the shaft, thereby realizing the real-time transportation of rock cuttings and eliminating the trouble of well cleaning.

[0028] Furthermore, the rotating conveying speed of the scraper conveyor 2 can be slower than the rotating cutting speed of the cutting head 3, so that each scraper 21 can carry more rock cuttings.

[0029] exist Figure 1 In this embodiment, the support arm 1 includes a support arm panel 11, a hinge portion 13 located at the top 15 of the support arm panel 11, and an ear seat 12 located in the middle of the support arm panel 11. The hinge portion 13 is used to hinge with the body of the equipment, and the ear seat 12 is used to connect to the body of the equipment via a hydraulic cylinder. The hydraulic cylinder can control the support arm 1 to rotate around the hinge portion 13, thereby controlling the swing of the support arm 1 so that the cutting head 3 at its end swings to the mining face 16. This connection method can be, but is not limited to, a hinge, thereby allowing the support arm 1 to swing with a larger amplitude. The design of the ear seat 12 and the hinge portion 13 facilitates the assembly and disassembly of the integrated cutting and slag removal device, and facilitates the maintenance of the integrated cutting and slag removal device.

[0030] As shown in the figure, the support arm panel 11 is elongated, with rounded ends. The scraper conveyor 2 is arranged around the outline of the elongated support arm panel 11. The elongated shape facilitates the installation of the conveyor belt of the scraper conveyor, and the rounded ends facilitate the installation of the cutting head 3.

[0031] When the support arm 1 swings, the scraper conveyor 2 moves along with the support arm 1. This integrated cutting and slag removal design of the support arm 1 allows the cut rock debris to be transported out while cutting.

[0032] Furthermore, a monitoring device (not shown in the figure) can be installed at the top 15 of the support arm 1. This monitoring device is used to monitor and observe the operation of the integrated cutting and slag removal device and the mining situation of the mining face in real time.

[0033] Figure 2 for Figure 1 A front view of an embodiment of the integrated cutting and slag removal device.

[0034] from Figure 2 As can be seen from the embodiments, the support arm 1 includes two opposing support arm panels 11, the scraper conveyor 2 is located on the inner side of the two opposing support arm panels 11, and the integrated cutting and slag removal device includes two cutting heads 3 located on the outer sides of the ends 14 of the two support arm panels 11 respectively.

[0035] A pipeline channel can be provided between the two support arm panels 11 and the upper side 17 and lower side 18 of the scraper conveyor 2. The pipeline channel can be equipped with power lines, spray pipes, etc. The power line is used to provide power to the cutting head 3 and the scraper conveyor 2, and the spray channel is used to cool the cutting head 3 and remove dust while cutting.

[0036] Combination Figure 1 It can be seen that the integrated cutting and slag removal device includes two hinge parts 13 respectively located at the top 15 of the two support arm panels 11, and located between the upper side 17 and the lower side 18 of the scraper conveyor 2, so as not to affect the operation of the scraper conveyor 2.

[0037] Specifically, in combination Figure 1 As can be seen, the support arm panel 11 has a panel mounting hole 4 at its top end 15, which is used to mount the hinge part 13. The hinge part 13 has a mounting bracket 41 and a protrusion 42 located in the middle of the mounting bracket 41, which is mounted in the panel mounting hole 4.

[0038] The mounting bracket 41 can be as follows Figure 1 As shown, multiple mounting feet extend from the central circle and are fixedly connected to the edge of the panel mounting hole 4. The protrusion 42 is located at the central circle, and as shown... Figure 2 As shown, the protrusion 42 protrudes from the support arm panel 11 and is used for hinge connection with the equipment body.

[0039] In other embodiments, the hinge portion 13 may also have only a protrusion 42 provided near the top end 15 of the support arm panel 11, the protrusion 42 protruding from the support arm panel 11 for hinged connection with the body of the device.

[0040] Combination Figure 1 It can also be seen that the integrated cutting and slag removal device includes two lugs 13 respectively disposed in the middle of the two support arm panels 11. Each lug 13 has a support leg 43 and a lug panel 45, which is mounted to the middle of the support arm panel 11 via the support leg 43. Figure 2 As shown, the support leg 43 supports the ear seat panel 45 away from the support arm panel 11. The ear seat panel 45 is provided with an ear seat mounting hole 44, which is used to hinge the hydraulic cylinder and connect to the equipment through the hydraulic cylinder.

[0041] from Figure 2 As can be seen in the embodiments, the integrated cutting and slag removal device includes two cutting heads 3, which are respectively installed on the outer sides of the two side support arm panels 11 near the ends 14. Each cutting head 1 has a slag guide plate 33, which can guide the cut rock cuttings to the intermediate scraper conveyor 2. The design of the cutting heads 3 on both sides of the ends 14 of the scraper conveyor 2 can expand the cutting area, improve cutting efficiency, and achieve better excavation results.

[0042] In an optional embodiment, a cutting head 3 can be installed on the upper side 17 of the two side arm panels 11 near the end 14. The cutting head 3 protrudes from the end 14 of the arm panel 11, and the width of the scraper conveyor 2 is greater than or equal to the width of the cutting head 3. During cutting, the scraper conveyor 2 is always located below the cutting head 3, thereby facilitating the complete collection of rock cuttings and debris cut by the cutting head.

[0043] Figure 3 for Figure 1 An enlarged schematic diagram of the cutting head portion of an embodiment of the integrated cutting and slag removal device.

[0044] As can be clearly seen from the figure, the cutting head 3 is located on both sides of the end 14 of the scraper conveyor 2, and the cutting head 1 is a roller-type cutting head. Specifically, the cutting head 3 includes a cylinder 31, cutting teeth 32, and slag guide plates 33. The slag guide plates 33 are spirally arranged along the surface of the cylinder 31, and the cutting teeth 32 are evenly arranged on the cylinder 31 along the spiral slag guide plates 33, with the slag guide plates 33 being lower than the cutting teeth 32. The spiral shapes of the slag guide plates on both sides are arranged opposite each other, so that the cut rock cuttings are concentrated at the middle scraper conveyor 2 by the spiral rotation.

[0045] Combination Figure 1 As can be seen, the cutting head 3 rotates close to the mining face 16, and its cutting teeth 32 cut the mining face 16. The cut rock cuttings fall into the slag guide plate 33 near the cutting teeth 32. Through the rotation of the cutting head 3, the rock cuttings spiral along the slag guide plate 33 and enter the scraper 21 of the scraper conveyor 2 in the middle, so that cutting and transportation of rock cuttings can be realized at the same time.

[0046] Figure 4 for Figure 1 A cross-sectional schematic diagram of the scraper of the scraper conveyor in an embodiment of the integrated cutting and discharging device.

[0047] exist Figure 4 In this embodiment, the scraper conveyor 2 has a scraper 22 fixedly installed at the end of the scraper 21. As shown in the figure, the cross section of the scraper 22 gradually narrows from the connection point with the scraper 21 towards the middle to form the cutting edge of the scraper 22, which is used to scrape the mining face 16.

[0048] It is understood that during the actual cutting process, the cutting head 3 cannot completely flatten the mining face 16, therefore, some protruding rock blocks will appear on the mining face 16. Combined with... Figure 1It can be seen that when the cutting head 3 is close to the mining face 16, the shovel 22 at the end of the scraper 21 of the scraper conveyor 2 is also close to the mining face 16. When encountering some protruding rock blocks in the mining face 16, the shovel 22 can shovel and cut the protruding rock blocks as the conveyor belt of the scraper conveyor 2 operates, so as to assist the cutting head 3 in cutting the mining face 16.

[0049] Figure 5 for Figure 1 A cross-sectional schematic diagram of another embodiment of the scraper conveyor of the integrated cutting and slag removal device.

[0050] from Figure 5 As can be seen from the embodiments, the scraper 21 has a blade 22 fixedly installed at the end of the scraper 21. The cross-section of the blade 22 can be a right-angled trapezoid, and the right-angled face of the right-angled trapezoid is fixedly connected to the end of the scraper 21. The inclined face of the right-angled trapezoidal blade 22 and the wider base face form a tip 23, which is used to cut the mining face to be cut.

[0051] In one embodiment, the wider base of the right-angled trapezoidal blade 22 can be flush with the surface of the scraper 21, which is used to hold the cut rock debris. Figure 1 It can be seen that during the transportation process, the tip 23 is used to cut the protruding rock blocks.

[0052] Furthermore, such as Figure 5 As shown, the wider base of the right trapezoid extends to the surface of the scraper 21, and the extension of the blade 22 protrudes from the surface of the scraper 21, forming a groove 26 on the surface of the scraper 21. The groove 26 is used to hold the rock cuttings and debris, and during the conveying process, the groove 26 can prevent the rock cuttings and debris from spilling out.

[0053] The shovel 22 can be like Figure 5 In one embodiment, the extension is fixed to the surface of the scraper 21 by bolts 24, or it can be fixed to the scraper 21 by means of welding, riveting, etc.

[0054] Furthermore, the protruding tip 23 of the scraper 22 can be a carbide insert. This carbide insert is highly hard and wear-resistant. The scraper 22 serves as a support for this carbide insert, facilitating the cutting of protruding rock blocks, reducing the wear rate and replacement frequency of the scraper 22, increasing its service life, and improving cutting efficiency. When the carbide insert wears out, it is easy to replace.

[0055] The present invention further provides a shaft tunneling machine having multiple of the aforementioned integrated cutting and discharging devices, and thus also has its corresponding advantages. The integrated cutting and discharging device has a simple structure.

[0056] Because the shaft tunneling machine of this invention can transport rock cuttings and excavated material simultaneously while tunneling and cutting the mining face, forming an integrated cutting and excavation system, there is no need to inject water into the shaft to transport the rock cuttings and excavated material. This achieves a water-free and pressure-free mining face, reducing the space occupied by the rock cuttings and excavated material transportation device. Moreover, this integrated cutting and excavation device has a simple structure, is easy to disassemble and assemble, is easy to maintain, and is adaptable to a wide range of geological conditions. Furthermore, monitoring equipment can be configured to monitor and observe the shaft tunneling machine and the condition of the shaft mining face at any time.

[0057] The present invention further provides a method for muck removal in vertical shaft excavation. This method employs the aforementioned vertical shaft excavator. Specifically, the cutting head 3 of the integrated cutting and muck removal device of the vertical shaft excavator and the scraper conveyor 2 are started and operated. The cutting head 3, as described above... Figure 1 As the arrow rotates, the conveyor belt of the scraper conveyor 2 moves as follows: Figure 1 Move in the direction of the arrow.

[0058] The hydraulic cylinder starts and controls the support arm 1 to rotate and swing around the hinge 13 via the lug 12, so that the cutting head 3 at the end of the support arm 1 is close to the mining face. The cutting head 3 cuts the mining face, and the slag guide plate 33 of the cutting head 3 guides the cut rock cuttings into the scraper 21 of the scraper conveyor 2. As the conveyor belt of the scraper conveyor 2 operates, the scraper blade 22 of the scraper 21 scrapes the protruding rock blocks on the mining face and transports the scraped rock blocks and cut rock cuttings out, completing the slag removal of the vertical shaft excavation.

[0059] The technical scope of this invention is not limited to the contents of the above specification. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the scope of this invention.
