[0002] The expansion of inclined shafts is still in the manual drilling and blasting stage. The inclined shaft expansion trolley is used for excavation and transportation of materials and equipment to the face. Personnel enter the working face through a safety ladder. The rock formation of the face is complex, and it is necessary to lay movable tracks when the equipment moves on the face. After the drilling is completed, the expansion trolley and equipment are removed, and then the movable track is removed. After the blasting is completed, the slag removal equipment is transported to the face by a trolley for slag removal. When the bucket is removing slag, the bucket teeth will be worn and need to be replaced.

[0003] Chinese patent application number CN202223099886.9 discloses an excavator bucket, including a bucket body, a bucket connecting shaft, and a bucket quick-change bucket tooth group. The bucket connecting shaft is welded to the top of the rear side of the bucket body, and a reserved position is set at the front side of the bottom end of the bucket body. The bucket quick-change bucket tooth group is fixed in the reserved position on the front end side of the bucket body through large and small long shaft pins. The front end of the inner bottom side of the bucket body is provided with neat protrusions and neat grooves, and the neat protrusions and neat grooves are arranged at intervals. The utility model optimizes the structural design of the excavator bucket, changes the traditional integrated excavator bucket structure, and improves it into a detachable and split excavator bucket structure. The structure is designed with a bucket quick-change bucket tooth group that can be quickly disassembled. Not only can the bucket teeth be replaced and disassembled separately, but also the front end plate of the bucket teeth can be replaced, which reduces the cost of replacing the entire bucket and improves the replacement efficiency. It is suitable for popularization and use.

[0004] Chinese patent application number CN202221903834.X discloses a bucket tooth and bucket tooth seat connection device, including a bucket, a bucket tooth seat is provided at the end of the bucket, a first limiting hole extending into the inner side of the bucket tooth seat is provided along the side of the bucket tooth seat, a mounting groove is provided on the front of the bucket tooth seat, a bucket tooth is detachably connected in the mounting groove, a second limiting hole is provided on the bucket tooth, the mounting groove and the first limiting hole have an intersection, and also include a limiting assembly, the limiting assembly includes a limiting rod, the limiting rod can be inserted into the first limiting hole and the second limiting hole in sequence and the bucket tooth is clamped, the bucket tooth can be installed in the mounting groove through the provided mounting groove, the first limiting hole and the second limiting hole are inserted into the limiting rod, and the two are connected, so that the design can be quickly replaced, and secondly, the second limiting hole is provided at different positions of the bucket tooth according to different needs, so that the angle between the bucket tooth and the bottom surface of the bucket can be adjusted, so that excavation operations can be performed on the above-mentioned specific terrain.

[0005] The above existing solutions may have the following problems during use: 1. When scraping, the bucket teeth will wear out after working for a long time, and they need to be replaced. When connecting, the pin is knocked into the bucket teeth and the tooth seat so that the two can be firmly connected; when removing, the pin is also knocked out. The disassembly and assembly process is more laborious. During the excavation process of the bucket teeth, the bucket teeth will hit the rock and there will be a small displacement between the tooth seat, which makes the pin easy to get stuck, further increasing the difficulty of disassembly and assembly. At the same time, due to the heavy weight of the bucket teeth, it is difficult to find the alignment and even more difficult to dock, making the installation process of the bucket teeth more troublesome.

[0006] 2. The tooth seat and bucket teeth are also connected and fixed by bolts. Compared with the pin-fixed connection method, bolts make it easier to disassemble the tooth seat and bucket teeth. However, during the slag removal process, the bolts are loosened by the collision of broken rocks, making the tooth seat and bucket teeth not firmly fixed, and causing wear between the tooth seat and bucket teeth. In severe cases, the bolts will directly detach, causing the tooth seat and bucket teeth to separate.

[0007] 3. There is a gap between the existing tooth seat and the bucket teeth, which is convenient for the bucket teeth to be matched on the tooth seat and then fixed on the bucket teeth. However, the remaining gap will be filled and blocked by slag during the slag removal process, so that the tooth seat firmly connects the bucket teeth together, resulting in a large force required to separate the tooth seat from the bucket teeth when replacing the bucket teeth, which is inconvenient to replace the bucket teeth.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By screwing the lockbolt into the bucket seat and the bucket tooth, the lockbolt moves against the sliding rod, and the sliding rod abuts against the bucket tooth for clamping. At the same time, during the movement of the sliding rod, the extrusion arc surface abuts against the fixed rod for movement, and the fixed rod is clamped in the placement hole of the bucket tooth, and the limiting ring moves in the lower chamber for extrusion, so that the ejector rod extends into the corresponding groove in the bucket tooth, realizing the fixed connection between the bucket seat and the bucket tooth.

At this time, the bucket tooth can be replaced, and the operation is simple.

[0020] 2. When fixing the lockbolt with a wrench, the wrench is sleeved on the lockbolt. Through the action of the extrusion surface, the lock prevention connecting rod enters the gap in the lockbolt.

After the fixed rod enters the placement hole, it will squeeze the compressed deformer. The compressed deformer is connected to the anti-loosening connecting rod, causing the balancing deformer to bulge, sealing the gap between the bucket seat and the bucket teeth, preventing the slag from entering the gap between the bucket seat and the bucket teeth when the device is scraping slag.

When the device performs slag removal operation, the leg devices 16 are extended and pressed against the inner wall of the inclined shaft to support and fix the frame 1 to prevent the slag removal system 18 from moving the frame 1 during the slag removal operation. The upper and lower ends of the slide rail 13 are provided with a pulley block 14 fixedly connected to the frame 1, and a traction wire 15 is connected to the pulley block 14, and the traction wire 15 is connected to an external hoisting device. The pulley block 14 is used to connect the traction wire 15, and the traction wire 15 is hoisted by an external hoisting device, thereby realizing the up and down movement of the frame 1 in the inclined shaft. The hoisting device is an existing device and will not be described in detail here.

[0026] See also Figure 3 , Figure 4 , Figure 5 , Figure 8 and Fig.10, considering that the bucket teeth will wear out after working for a long time during slagging, they need to be replaced. When connecting, the pin shaft is knocked into the bucket teeth and the tooth seat so that the two can be firmly connected; when removing, the pin shaft is also knocked out, and the disassembly and assembly process is more laborious. Sometimes the pin shaft is easily stuck, which further increases the difficulty of disassembly and assembly. At the same time, due to the heavy weight of the bucket teeth, it is difficult to align them accurately, and it is even more difficult to dock them, making the installation process of the bucket teeth more troublesome. The bucket seat 3 is slidably connected with a slide bar 31. By screwing the anti-loosening bolt 5 into the bucket seat 3 and the bucket tooth 4, the anti-loosening bolt 5 moves against the slide bar 31, and the slide bar 31 is clamped against the bucket tooth 4. The lower end of the slide bar 31 is engaged with the bucket tooth 4, and the bucket seat 3 is symmetrically provided with a slide bar 31. The locking cam 332 is provided with a plurality of locking cams 314, wherein the locking cam 332 is provided with a plurality of locking cams 316, and the locking cams 318 are provided with a plurality of locking cams 319. The guide block 313 in the circumferential direction, the slide bar 31 is provided with a guide groove corresponding to the guide block 313, and the guide block 313 slides correspondingly with the guide groove inside the bucket seat 3, so that the slide bar 31 can slide up and down smoothly to prevent the slide bar 31 from rotating or getting stuck. The upper end of the slide bar 31 is provided with a limit seat 33, and the limit seat 33 is connected to the bucket seat 3 by a spring. By arranging a spring between the limit seat 33 and the bucket seat 3, when the slide bar 31 moves downward, the spring will be compressed. After the anti-loosening bolt 5 is removed, the elastic force of the limit seat 33 will push the slide bar 31 upward, thereby causing the lower end of the slide bar 31 to disengage from the bucket tooth 4, thereby releasing the fixation with the bucket seat 3 and the bucket tooth 4. The bucket seat 3 has two symmetrically distributed The lower chamber 34 and two symmetrically distributed upper chambers 35 are connected one by one. The upper chambers 35 are slidably connected with top columns 36, and the top columns 36 are engaged with the bucket teeth 4. At the same time, during the movement of the slide bar 31, the slide bar 31 moves against the limit seat 33, and the piston column 331 on the limit seat 33 slides and squeezes in the lower chamber 34, so that the top column 36 in the upper chamber 35 moves upward and engages with the groove on the bucket tooth 4 to complete the fixation of the bucket seat 3 and the bucket tooth 4. After the anti-loosening bolt 5 is released, the spring moves upward against the limit seat 33, and the piston column 331 moves upward to extract the gas in the upper chamber 35, so that the top column 36 is restored, and the fixation of the bucket seat 3 and the bucket tooth 4 is released. The bucket seat 3 is provided with an anti-slip groove 38.The anti-skid groove 38 is clamped on the grab bucket 26, and the bucket seat 3 and the grab bucket 26 are fixed by bolts. The anti-skid groove 38 and the grab bucket 26 are clamped to prevent the anti-skid groove 38 from sliding between the grab bucket 26 during operation.

[0027] See also Fig.10 Considering that there is a gap between the tooth seat and the bucket tooth, it is convenient to match the bucket tooth to the tooth seat and then fix the bucket tooth. However, the remaining gap will be filled and blocked by slag during the slag removal process, so that the tooth seat firmly connects the bucket teeth together, resulting in that it takes a lot of force to separate the tooth seat from the bucket tooth when replacing the bucket tooth, which is inconvenient to replace the bucket tooth. The inner wall of the bucket tooth 4 is provided with two symmetrically arranged placement holes 41, and the placement holes 41 are each provided with a compressed deformation body 42. A U-shaped balancing deformation body 43 is fixed in the bucket tooth 4. By setting the compressed deformation body 42 and the balancing deformation body 43, the slide rod 31 is moved to drive the fixing rod 32 moves, and the fixing rod 32 enters the placement hole 41 to squeeze the compressed deformer 42. The compressed deformer 42 is connected to the anti-loosening connecting rod 53, causing the balancing deformer 43 to bulge, and the gap between the bucket seat 3 and the bucket tooth 4 is sealed, preventing the slag from entering the gap between the bucket seat 3 and the bucket tooth 4 when the device is scraping slag. When the sliding rod 31 moves upward, the fixing rod 32 loses the squeezing force, and the balancing deformer 43 and the compressed deformer 42 need to be restored. The force generated by the restoration of the balancing deformer 43 and the compressed deformer 42 will push the fixing rod 32 to restore and enter the bucket seat 3, thereby releasing the fixation between the bucket seat 3 and the bucket tooth 4.

[0028] See also Figure 5 and Figure 6, considering that the tooth seat and the bucket tooth are also connected and fixed by bolts, compared with the pin-fixed connection method, the bolts make it easier to disassemble the tooth seat and the bucket tooth. However, in the process of slagging, the bolts are loosened by the collision of broken rocks, making the fixation between the tooth seat and the bucket tooth not firm, and causing wear between the tooth seat and the bucket tooth. In severe cases, the bolts will directly detach, causing the tooth seat and the bucket tooth to separate. A gasket 51 is fixed to the outer wall of the anti-loosening bolt 5, and a connecting ring 52 fixedly connected to the anti-loosening bolt 5 is provided on the upper end of the gasket 51. A plurality of anti-loosening connecting rods 53 are slidably connected to the inside of the anti-loosening bolt 5 along its circumference. A spring sheet 54 is provided between the anti-loosening connecting rod 53 and the anti-loosening bolt 5. Through the setting of the spring sheet 54, the anti-loosening connecting rod 53 After the movement, the spring piece 54 will be compressed, and after the external force is released, the spring piece 54 will restore against the anti-loosening connecting rod 53, and the lower end of the anti-loosening connecting rod 53 is clamped with the bucket seat 3, and a connecting hole 37 is provided on the bucket seat 3, and the connecting hole 37 corresponds to the anti-loosening bolt 5, and the cross-section of the connecting hole 37 is an inverted convex shape, and a plurality of anti-loosening grooves 371 are provided on the lower inner wall of the connecting hole 37 along its circumference, and the anti-loosening grooves 371 correspond to the anti-loosening connecting rod 53 one by one, and a plurality of circles of anti-loosening blocks 372 distributed in an annular manner are fixed to the upper end of the connecting hole 37, and the upper inner wall of the connecting hole 37 is serrated, and by setting a serrated and triangular anti-loosening block 372 in the connecting hole 37, when the gasket 51 is located in the connecting hole 37, the gasket 51 is squeezed The cam 532 is engaged with the anti-loosening groove 371, and the cam 532 is engaged with the anti-loosening block 372 to prevent the anti-loosening bolt 5 from being loosened and reversed. 4 is disengaged, the anti-loosening bolt 5 is threadedly connected to the bucket tooth 4 through the connecting ring 52, and a sliding gap is provided inside the anti-loosening bolt 5 for the anti-loosening connecting rod 53. By providing a gap inside the anti-loosening bolt 5, space is reserved for the movement of the anti-loosening connecting rod 53, so that the anti-loosening connecting rod 53 can be easily moved. The anti-loosening connecting rod 53 is C-shaped, and the upper end of the anti-loosening connecting rod 53 is an extrusion surface 531. When the wrench is connected to the anti-loosening bolt 5, the wrench will be pressed against the extrusion surface 531, thereby squeezing the anti-loosening connecting rod 53 to extend into the anti-loosening bolt 5. The lower end of the anti-loosening connecting rod 53 is a convex block 532, and the convex block 532 corresponds to the anti-loosening groove 371. The gasket 51 corresponds to the anti-loosening block 372. The depth of the anti-loosening groove 371 is greater than the height of the convex block 532.The number of the anti-loosening grooves 371 is greater than the number of the anti-loosening connecting rods 53. By setting the depth of the anti-loosening grooves 371 to be greater than the height of the protrusions 532 and setting the number of the anti-loosening grooves 371 to be greater than the number of the anti-loosening connecting rods 53, it is easy for the protrusions 532 to engage with the anti-loosening grooves 371, and prevents the protrusions 532 from failing to engage with the anti-loosening grooves 371.

[0029] See also Figure 5 and Figure 7 , considering that the top column 36 rises, and after the top column 36 enters the bucket tooth 4, the top column 36 no longer moves, in order to prevent the piston column 331 from being unable to continue to move downward, the lower end of the limit seat 33 is fixed with a limit ring 332, and the lower end of the limit seat 33 is fixed with two symmetrically arranged piston columns 331, and the piston columns 331 correspond to the lower chamber 34 one by one. The piston column 331 slides in the lower chamber 34, and the top column 36 is clamped in the bucket tooth 4 through the cooperation of the limit seat 33 with the lower chamber 34 and the upper chamber 35. The interior of the top column 36 is slidably connected with a piston block 361, and the piston block 3 A spring is fixed to the upper end of 61, and the upper end of the spring is fixedly connected to the piston block 361. A hole corresponding to the top column 36 is opened inside the bucket tooth 4. When the piston column 331 moves down to squeeze the lower chamber 34, it pushes the top column 36 to rise. After the top column 36 enters the bucket tooth 4, the top column 36 no longer moves. In order to prevent the piston column 331 from being unable to move further downward, piston blocks 361 and 362 are set in the top column 36. When the top column 36 and the bucket tooth 4 are abutted, the piston column 331 continues to squeeze, and the piston block 361 will move in the top column 36, and the piston block 361 will squeeze 362.

[0030] See also Fig. 9 , Fig.10 and Fig.11, considering that when the bucket tooth 4 breaks the rock, the cutting head 44 and the cutting edge 45 of the bucket tooth 4 need to have greater rigidity to prevent deformation of the cutting head 44 and the cutting edge 45. A plurality of triangular prism-shaped fixing strips are fixed at the upper end of the bucket seat 3. Grooves corresponding to the fixing strips are formed in the bucket tooth 4. A cutting head 44 is provided on the bucket tooth 4. Cutting edges 45 are provided on the front and rear sides of the cutting head 44. Reinforcing ribs A46 corresponding to the cutting edges 45 one by one are fixed at the upper end of the cutting head 44. When the bucket tooth 4 is inserted into the bucket seat 3, the fixing strips on the bucket seat 3 will first be clamped with the grooves on the bucket tooth 4, preventing the bucket tooth 4 from slipping off the bucket seat 3 without being fixed.

Hydraulic devices are provided between the arm seat 23 and the boom 24, between the boom 24 and the dipper arm 25, and between the dipper arm 25 and the scraper bucket 26. By providing hydraulic devices between the arm seat 23 and the boom 24, between the boom 24 and the dipper arm 25, and between the dipper arm 25 and the scraper bucket 26, it is beneficial to adjust the angle of the scraper bucket 26 to achieve the effect of scraping or crushing rocks.

[0032] When the present invention is used: First, the frame 1 is placed in the inclined shaft under construction, and the traction wire 15 is hoisted by an external hoisting device. At the same time, the frame 1 is moved up and down in the inclined shaft through the cooperation of the walking wheel 11 and the track 12. When it is necessary to remove slag, the hoisting device stops working, and the leg device 16 is extended and pressed against the inner wall of the inclined shaft to support and fix the frame 1 to prevent the frame 1 from moving when the slag removal system 18 is working. The slag removal and rock crushing operations are realized by the slag removal system 18. Then, after working for a long time, the teeth 4 on the bucket 26 will be worn and need to be replaced; The locking cam 33 is then released, and the locking cam 33 is released, and the locking cam 33 is in a state of being pushed upward, so that the locking cam 33 is released, and the locking cam 33 is in a state of being pushed upward, so that the locking cam 33 is released, and the locking cam 33 is in a state of being pushed upward, so that the locking cam 33 is in a state of being pushed upward ... Finally, place the new bucket tooth 4 on the bucket seat 3. The fixing strip on the bucket seat 3 will first engage with the groove on the bucket tooth 4 to prevent the bucket tooth 4 from sliding off the bucket seat 3 without being fixed. Connect the wrench to the anti-loosening bolt 5, squeeze the anti-loosening connecting rod 53, and fix the anti-loosening bolt 5 on the bucket tooth 4. After removing the wrench, the spring piece 54 pushes the anti-loosening connecting rod 53 to restore and extend. At the same time, the protrusion 532 is engaged in the anti-loosening groove 371, and the gasket 51 and the anti-loosening connecting rod 53 are added. The block 372 is pressed against the washer 51, and the washer 51 is fully and perfectly fitted with the serrated anti-loosening block 372 after being squeezed to prevent the anti-loosening bolt 5 from being reversed and loosened. During the fixing process of the anti-loosening bolt 5, the anti-loosening bolt 5 moves against the slide bar 31, and the extruded arc surface 312 on the slide bar 31 is pressed against the fixed rod 32. Then, during the downward movement of the slide bar 31, the extruded arc surface 312 pushes the fixed rod 32 to move slowly, and the end of the fixed rod 32 is then slowly The bucket tooth 4 is clamped in the placement hole 41 to complete the clamping and fixing with the placement hole 41. The lower end of the slide bar 31 is re-engaged and fixed with the bucket tooth 4. The slide bar 31 moves against the limit seat 33. The piston column 331 on the limit seat 33 slides and squeezes in the lower chamber 34, so that the top column 36 in the upper chamber 35 moves upward. The top column 36 is fixed corresponding to the groove on the bucket tooth 4 to achieve the fixation of the bucket seat 3 and the bucket tooth 4. When the slide bar 31 moves, the fixing rod 32 is driven to move. After the fixing rod 32 enters the placement hole 41, it squeezes the compressed deformation body 42. The compressed deformation body 42 is connected to the anti-loosening connecting rod 53, causing the balancing deformation body 43 to bulge, thereby sealing the gap between the bucket seat 3 and the bucket tooth 4, preventing the slag from entering the gap between the bucket seat 3 and the bucket tooth 4 when the device is scraping slag. At the same time, the fixing rod 32 enters the placement hole 41, realizing the engagement of the fixing rod 32 and the placement hole 41, thereby completing the entire fixation of the bucket tooth 4 and the bucket seat 3.
