Description

Technical Field

[0001] This application relates to the technical field of muck loaders, and in particular to a modular muck loader scraper quick-change structure. Background Technology

[0002] Slag loaders are widely used in mining, tunnel excavation, and other engineering operations. Their scrapers are one of the key components, directly contacting rocks, slag, and other materials during operation, and bearing significant friction and impact forces, making them prone to wear. When the scrapers wear down to a certain extent, they need to be replaced promptly to ensure the normal operating efficiency and quality of the slag loader.

[0003] A search revealed Chinese Patent Publication No. CN219566609U, which discloses a scraper for a slag remover, including a slag remover bucket with a cleaning mechanism. A support box is fixedly connected to the bottom of the slag remover bucket, and a storage groove is provided on the support box. Two servo motors are fixedly installed at the end of the support box, and the output shafts of the two servo motors extend into the inner cavity of the storage groove and are fixedly connected to threaded rods. Extension plates are threaded onto the two threaded rods, and scraper strips are installed at the ends of the extension plates. The sides of the extension plates are in contact with the inner wall of the storage groove, and a protective cover is provided at the end of the support box outside the servo motors.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, the retaining plate is connected to the muck loader via bolts. When the retaining plate needs to be replaced, the disassembly of multiple bolts increases the working time, thereby reducing the efficiency of the device. To address the issue of the slow replacement speed affecting work efficiency in the prior art, this application employs a modular design. This allows for replacement of only the scraper section when the scraper wears out, eliminating the need to disassemble the entire complex structure and reducing maintenance workload and costs.

[0030] The following is in conjunction with the appendix Figure 1-9 The accompanying drawings provide a further detailed description of this application. The technical solutions in the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] This application discloses a quick-change structure for the scraper 2 of a modular muck remover. For example... Figure 1 As shown, the device includes a body 1, on which a quick-release mechanism is provided. The body 1 is connected to a scraper 2 via the quick-release mechanism. The quick-release mechanism includes a quick-release component and a fixing component. The quick-release component includes a positioning groove 4 on the body 1 and a positioning block 3 on the scraper 2. The positioning block 3 is adapted to the positioning groove 4. A first fixing hole 5 is provided on the end face of the positioning groove 4, and a second fixing hole 6 adapted to the first fixing hole 5 is provided on the positioning block 3. A first nut 7 is provided on the first fixing hole 5, and a rotating rod 8 is threadedly connected to the first nut 7.

[0032] In this embodiment, the connection between the scraper 2 and the machine body 1 is achieved by inserting the positioning block 3 into the positioning groove 4; at this time, the first fixing hole 5 and the second fixing hole 6 coincide, and by rotating the rotating rod 8, the rotating rod 8 is inserted into the first fixing hole 5 and the second fixing hole 6 to fix the connected scraper 2 and the machine body 1; through the fixing component, the connection between the rotating rod 8 and the scraper 2 and the machine body 1 is made tighter.

[0033] Please see Figure 2 The fixing component includes a first radial groove 9, a second radial groove 10 and an axial hole 11 formed on the rotating rod 8; a stop rod 12 is slidably connected in the axial hole 11; a locking block 13 is slidably connected in the first radial groove 9 and a fixing block 14 is slidably connected in the second radial groove 10.

[0034] In this embodiment, the abutment 12 is inserted into the axial hole 11, causing the fixing block 14 in the second radial groove 10 to slide outward in the radial direction, thereby making the fixing block 14 contact and tighten with the inner wall of the first fixing hole 5; the locking block 13 locks the abutment 12 when it reaches the working position, thereby making the tightening of the fixing block 14 more secure.

[0035] Please see Figure 7 The locking block 13 is provided with a first inclined surface and a second inclined surface, and a first spring is provided between the locking block 13 and the side wall of the first radial groove 9; the end face of the rotating rod 8 is provided with a through groove communicating with the first radial groove 9, and an unlocking rod 15 is slidably connected in the through groove, and a third inclined surface is provided at the lower end of the unlocking rod 15; a second spring is provided between the end face of the unlocking rod 15 away from the first radial groove 9 and the end face of the rotating rod 8; the abutment rod 12 is provided with a fourth inclined surface;

[0036] In this embodiment, when it is necessary to lock the rotating rod 8 to the first fixing hole 5, the abutment 12 is inserted into the axial hole 11, the fourth inclined surface on the abutment 12 contacts the first inclined surface on the locking block 13, and drives the locking block 13 to slide outward along the radial direction of the rotating rod 8, and compresses the first spring.

[0037] When the abutment rod 12 is fully inserted, the first spring drives the locking block 13 to reset, and the side wall of the locking block 13 abuts against the end face of the abutment rod 12, thus locking the abutment rod 12.

[0038] When unlocking is required, pressing down on the unlocking lever 15 causes the third inclined surface of the unlocking lever 15 to drive the locking block 13 to slide outward through the second inclined surface on the locking block 13, compressing the first spring and preventing the locking block 13 from locking the abutment lever 12.

[0039] Please see Figure 6 A third spring is provided between the abutment 12 and the bottom wall of the axial hole 11; a connecting part is provided on the bottom wall of the axial hole 11, a fourth spring is provided between the fixing block 14 and the connecting part, and a fifth inclined surface adapted to the fourth inclined surface is provided on the fixing block 14;

[0040] In this embodiment, when the abutment rod 12 is inserted, the fourth inclined surface on the abutment rod 12 drives the fixing block 14 to slide outward along the radial direction of the rotating rod 8 through the fifth inclined surface, and compresses the fourth spring, so that the fixing block 14 is pressed tightly against the inner wall of the first fixing hole 5 and the second fixing hole 6, thereby locking the rotating rod 8.

[0041] When unlocked, the third spring drives the stop rod 12 to pop outward, and the stop rod 12 no longer contacts the fixing block 14. The fourth spring drives the fixing block 14 to reset, and the fixing block 14 no longer contacts the inner wall of the first fixing hole 5 and the second fixing hole 6.

[0042] Please see Figure 2 The outer wall of the rotating rod 8 is slidably connected to a gear 16; the machine body 1 is provided with a first support frame 17, a second support frame 18 and a third support frame, the first support frame 17 is provided with a second nut 19, and the second nut 19 is threadedly connected to a screw; a sliding rod 20 is slidably connected between the second support frame 18 and the third support frame, and a rack 21 adapted to the gear 16 is provided on the sliding rod 20; one end of the sliding rod 20 is rotatably connected to the screw; a rotating handle 22 is provided at one end of the screw;

[0043] In this embodiment, a slide rail is provided on the outer wall of the rotating rod 8 in the radial direction, and a through hole is provided on the end face of the gear 16, and a slide groove adapted to the slide rail is provided in the through hole.

[0044] By rotating the handle 22, the screw drives the sliding rod 20 to move the rack 21 to one side. The moving rack 21 meshes with and drives the gear 16 to rotate. The gear 16 drives the rotating rod 8 to rotate, so that the rotating rod 8 is inserted into the first fixing hole 5 and the second fixing hole 6.

[0045] Because the sliding rod 20 is provided with a limit block and the second bracket is provided with a limit groove, and the sliding rod 20 and the screw are slidably connected, the screw will not drive the sliding rod 20 to rotate.

[0046] The implementation principle of the modular slag remover scraper 2 quick replacement structure in this application embodiment is as follows: by inserting the positioning block 3 into the positioning groove 4, the scraper 2 is connected to the machine body 1; at this time, the first fixing hole 5 and the second fixing hole 6 coincide.

[0047] Rotate the handle 22 to drive the screw to drive the sliding rod 20 to move the rack 21 to one side. The moving rack 21 meshes with the gear 16 to rotate. The gear 16 drives the rotating rod 8 to rotate, so that the rotating rod 8 is inserted into the first fixing hole 5 and the second fixing hole 6 to fix the connected scraper 2 to the machine body 1.

[0048] When it is necessary to lock the rotating rod 8 with the first fixing hole 5, the abutment 12 is inserted into the axial hole 11, the fourth inclined surface on the abutment 12 contacts the first inclined surface on the locking block 13, and drives the locking block 13 to slide outward along the radial direction of the rotating rod 8, and compresses the first spring.

[0049] When the stop rod 12 is inserted, the fourth inclined surface on the stop rod 12 drives the fixing block 14 to slide outward along the radial direction of the rotating rod 8 through the fifth inclined surface, and compresses the fourth spring, so that the fixing block 14 is pressed tightly against the inner wall of the first fixing hole 5 and the second fixing hole 6, thus locking the rotating rod 8.

[0050] When the abutment rod 12 is fully inserted, the first spring drives the locking block 13 to reset, and the side wall of the locking block 13 abuts against the end face of the abutment rod 12, thus locking the abutment rod 12.

[0051] When unlocking is required, by pressing down on the unlocking lever 15, the third inclined surface of the unlocking lever 15 drives the locking block 13 to slide outward through the second inclined surface on the locking block 13, and compresses the first spring, so that the locking block 13 no longer locks the abutment lever 12.

[0052] The third spring drives the stop rod 12 to pop outward, and the stop rod 12 no longer contacts the fixing block 14. The fourth spring drives the fixing block 14 to reset, and the fixing block 14 no longer contacts the inner wall of the first fixing hole 5 and the second fixing hole 6.

[0053] At this point, rotate the handle 22 in the opposite direction. The sliding rod 20 drives the rack 21 to rotate in the opposite direction, which in turn drives the gear 16 to rotate the rotating rod 8 in the opposite direction. This causes the abutment rod 12 to gradually move out of the second fixing hole 6, thus completing the unlocking of the scraper 2 from the body 1.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
