Description

TECHNICAL FIELD

[0001] The utility model belongs to toothed roll crusher technical field, concretely relates to a toothed roll crusher toothed roll. BACKGROUND

[0002] The double-toothed roll crusher utilizes high extrusion force generated by relative rotation of two wear-resistant alloy toothed rolls to crush high-calcium stone, and can quickly crush the high-calcium stone into the required particle size under the action of extrusion, shearing and meshing, greatly improves the production efficiency, meets the needs of large-scale production, and can effectively adjust the particle size of the product by controlling the gap between the two rolls, so as to ensure that the size of the crushed high-calcium stone meets the production requirements and meets the specific needs of different industries for the particle size of high-calcium stone, such as the particle size requirement of high-calcium stone for concrete production in the construction industry.

[0003] When the toothed roll on the crusher is crushing, the overall rotating toothed roll drives the multiple crushing teeth on the outer periphery to rotate and crush the high-calcium stone by clawing and shearing. When a hard stone block is encountered, the overall rotating toothed roll causes a crushing tooth to be stuck on the stone block, so that the overall inertial rotation force acts on the crushing tooth stuck on the stone block, causing the crushing tooth to be instantaneously braked, resulting in an opposite force between the crushing tooth and the toothed roll, and thus easily causing the separation of the crushing tooth and the toothed roll, and the breakage of the crushing tooth, thereby reducing the crushing effect and service life of the toothed roll. SUMMARY

[0004] The utility model aims at providing a toothed roll crusher toothed roll, which can solve the above technical problems.

[0005] The technical scheme adopted by the utility model is as follows:

[0006] The utility model provides a toothed roll crusher toothed roll, which comprises a central shaft, a fastening mechanism, two symmetrical buffer mechanisms and a stabilizing mechanism, the fastening mechanism, the two buffer mechanisms and the stabilizing mechanism are all arranged on the central shaft, the two buffer mechanisms are arranged between the fastening mechanism and the stabilizing mechanism, the opposite sides of the fastening mechanism and the stabilizing mechanism are respectively provided with two symmetrical sealing covers, the outer periphery of the fastening mechanism, the two buffer mechanisms and the stabilizing mechanism is provided with a plurality of interval-distributed short-tooth groups and long-tooth groups, and the shape of the long-tooth group is T-shaped.

[0007] The fastening mechanism comprises a fastening roll, two first force-accumulating springs and a first rotating ring, first insertion grooves are formed on the two sides of the fastening roll, one of the sealing covers is inserted into one of the first insertion grooves in a matched mode, a first fixing plate is arranged in the fastening roll, a jacking sleeve shaft is arranged on the first fixing plate at the center of the fastening roll, a transmission rod is arranged on the central shaft, and the jacking sleeve shaft is sleeved with the transmission rod through a formed transmission hole.

[0008] The buffer mechanism includes a buffer roller and two rotating plates. The buffer roller has interlocking rings with misaligned inner and outer circumferential surfaces on both sides. A second fixing plate is provided inside the buffer roller. A stabilizing sleeve shaft is provided on the second fixing plate at the center of the buffer roller. An expansion shaft connected to a transmission rod is provided on the central shaft. The stabilizing sleeve shaft is sleeved with the expansion shaft through a formed sleeve hole. The two interlocking rings on the two buffer rollers are interconnected and interlocked.

[0009] When the toothed roller of the toothed roller crusher described above is used, if the short or long tooth groups on the surface of the buffer roller on the buffer mechanism get stuck while crushing high-calcium stone blocks, the rotating fastening and stabilizing mechanisms will drive the first and second fixed plates to continue rotating. This will cause the first and second fixed bolts to pull the first or second energy storage spring, thereby buffering the short and long tooth groups on the buffer roller that have stopped rotating due to the sticking. In this way, the short and long tooth groups on the outer periphery of the buffer roller can provide static buffering for the stone blocks. At the same time, due to the sticking, the tension on the first or second energy storage spring increases, thereby continuing to crush and discharge the stone blocks. This allows the first or second energy storage spring to pull the buffer roller to flip and reset, thereby continuing the crushing process. This buffering and protection of the short and long tooth groups can improve the service life of the toothed roller.

[0010] Preferably, the stabilizing mechanism includes a synchronizing roller, a second rotating ring, and two second energy storage springs. The synchronizing roller has second insertion grooves formed on both sides, one of which is inserted into the other sealing cover. A third fixing plate is provided inside the synchronizing roller. A fixing sleeve shaft connected to the central shaft is provided on the third fixing plate at the center of the synchronizing roller. Second fixing bolts are respectively sleeved on both sides of the second energy storage springs. One of the second fastening bolts is screwed onto the third fixing plate. A top-tightening plate slidably sleeved on the central shaft is tightened against the side of the top-tightening sleeve shaft by bolts.

[0011] Preferably, the second rotating ring is disposed inside the synchronous roller and sleeved on the outer periphery of the fixed sleeve shaft. Two second fastening bolts and two other second fixing bolts are sleeved on the second rotating ring. First fixing bolts are sleeved on both sides of the first energy storage spring. One of the first fixing bolts is spirally disposed on the first fixing plate. The first rotating ring is disposed inside the fastening roller. Two first fastening bolts and two other first fixing bolts are sleeved on the first rotating ring.

[0012] Preferably, two rotating plates are symmetrically arranged on the second fixing plate with the stabilizing sleeve shaft as the center. The two rotating plates are respectively located on both sides of the first fixing plate inside the fastening roller or on both sides of the third fixing plate inside the synchronous roller.

[0013] Preferably, two rotating plates inside one of the buffer rollers press the first rotating ring onto the rotating plates by two threaded first fastening bolts, and the first fixing bolt slides through the first rotating ring and is threadedly connected to the rotating plate on one of the buffer rollers.

[0014] Preferably, the second rotating ring is pressed onto the rotating plate by two threaded second fastening bolts in the other buffer roller, and the second fixing bolt slides through the second rotating ring and is threadedly connected to the rotating plate on the other buffer roller.

[0015] Preferably, the outer periphery of the fastening roller, the two buffer rollers and the synchronization roller are provided with multiple short tooth groups and long tooth groups distributed at intervals, and the insertion ring is inserted into the first insertion groove and the second insertion groove.

[0016] The beneficial effects are:

[0017] This invention, through a fastening mechanism, two buffering mechanisms, and a stabilizing mechanism, allows the short and long toothed groups on the buffering mechanism to stretch the first energy storage spring by driving the first rotating ring on the fastening mechanism or the second rotating ring on the stabilizing mechanism by driving the second energy storage spring when the short and long toothed groups on the buffering mechanism are jammed by a stone. This provides elastic tension buffering for the rotating buffer roller, thereby reducing the inertial shear force on the short or long toothed groups during rotation. It also facilitates buffering and crushing of harder, high-calcium stones, and improves the service life of the short and long toothed groups on the toothed roller. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-5 As shown, a toothed roller crusher includes a central shaft 1, a fastening mechanism 2, two symmetrical buffer mechanisms 3 and a stabilizing mechanism 4. The fastening mechanism 2, the two buffer mechanisms 3 and the stabilizing mechanism 4 are all arranged on the central shaft 1. The two buffer mechanisms 3 are arranged between the fastening mechanism 2 and the stabilizing mechanism 4. Two symmetrical sealing covers 5 are respectively arranged on the opposite sides of the fastening mechanism 2 and the stabilizing mechanism 4. Multiple short tooth groups 6 and long tooth groups 7 are arranged at intervals on the outer periphery of the fastening mechanism 2, the two buffer mechanisms 3 and the stabilizing mechanism 4. The long tooth group 7 is T-shaped.

[0027] The fastening mechanism 2 includes a fastening roller 201, two first energy storage springs 205 and a first rotating ring 208. Both sides of the fastening roller 201 are formed with first insertion grooves 202. One of the sealing caps 5 is inserted into one of the first insertion grooves 202. A first fixing plate 203 is provided inside the fastening roller 201. A top-tightening sleeve shaft 204 is provided on the first fixing plate 203 at the center of the fastening roller 201. A transmission rod 9 is provided on the central shaft 1. The top-tightening sleeve shaft 204 is sleeved with the transmission rod 9 through a formed transmission hole.

[0028] The buffer mechanism 3 includes a buffer roller 301 and two rotating plates 305. The buffer roller 301 has two interlocking rings 302 with misaligned inner and outer circumferential surfaces on both sides. The buffer roller 301 has a second fixing plate 303 inside. The second fixing plate 303 has a stabilizing sleeve shaft 304 located at the center of the buffer roller 301. The central shaft 1 has an expanding shaft 8 connected to the transmission rod 9. The stabilizing sleeve shaft 304 is sleeved with the expanding shaft 8 through a formed sleeve hole. The two buffer rollers 301 have two interlocking rings 302 that are opposite to each other.

[0029] As an optional implementation, the stabilizing mechanism 4 includes a synchronous roller 401, a second rotating ring 405, and two second energy storage springs 406. The synchronous roller 401 has second insertion grooves 402 formed on both sides, one of which is inserted into the other sealing cover 5. A third fixing plate 403 is provided inside the synchronous roller 401. A fixing sleeve shaft 404 connected to the central shaft 1 is provided on the third fixing plate 403 at the center of the synchronous roller 401. Second fixing bolts 407 are respectively fitted on both sides of the second energy storage springs 406. One second fastening bolt 408 is spirally mounted on the third fixing plate 403. A top-tightening plate 10, slidably fitted on the central shaft 1, is tightened against the side of the top-tightening sleeve shaft 204 by bolts. This arrangement allows the top-tightening plate 10 to tighten the fastening roller 201, thereby driving the two buffer rollers 301 to fully engage and improving the sealing effect.

[0030] See attached document Figure 5 The second rotating ring 405 is disposed inside the synchronous roller 401 and sleeved on the outer circumference of the fixed sleeve shaft 404. Two second fastening bolts 408 and two other second fixing bolts 407 are sleeved on the second rotating ring 405. First fixing bolts 206 are sleeved on both sides of the first energy storage spring 205. One of the first fixing bolts 206 is spirally disposed on the first fixing plate 203. The first rotating ring 208 is disposed inside the fastening roller 201. Two first fastening bolts 207 and two other first fixing bolts 206 are sleeved on the first rotating ring 208. This arrangement facilitates convenient installation and fixing during installation, thereby improving the assembly and fixing effect.

[0031] See attached document Figure 4 Two rotating clamping plates 305 are symmetrically arranged on the second fixed plate 303 with the stabilizing sleeve shaft 304 as the center. The two rotating clamping plates 305 are respectively located on both sides of the first fixed plate 203 in the fastening roller 201 or on both sides of the third fixed plate 403 in the synchronous roller 401. In this way, the rotating clamping plates 305 can be locked with the first fixed plate 203 or the third fixed plate 403 after rotating to a certain angle, thereby ensuring the continuous rotation of the buffer roller 301.

[0032] Furthermore, two rotating plates 305 inside one of the buffer rollers 301 are connected by two threaded first fastening bolts 207 to press the first rotating ring 208 onto the rotating plate 305. The first fixing bolt 206 slides through the first rotating ring 208 and is threadedly connected to the rotating plate 305 on one of the buffer rollers 301. This arrangement allows the first fixing bolt 206 to transmit the elastic tension generated by the first energy storage spring 205 to the first rotating ring 208, thereby facilitating the rotation plate 305 to elastically buffer the buffer roller 301.

[0033] Furthermore, the two rotating plates 305 inside the other buffer roller 301 are pressed onto the second rotating ring 405 by two threaded second fastening bolts 408. The second fixing bolt 407 slides through the second rotating ring 405 and is threadedly connected to the rotating plate 305 on the other buffer roller 301. With this arrangement, the second storage spring 406, under the fixed support of the third fixing plate 403, can be synchronously stressed by the second fastening bolts 408, thereby facilitating the elastic tension support when the other buffer roller 301 rotates.

[0034] Furthermore, the outer periphery of the fastening roller 201, the two buffer rollers 301, and the synchronizing roller 401 are all provided with multiple short tooth groups 6 and long tooth groups 7 distributed at intervals. The insertion ring 302 is inserted into the first insertion groove 202 and the second insertion groove 402. In this way, the buffer roller 301 can be inserted into the first insertion groove 202 on the fastening roller 201 or the second insertion groove 402 on the synchronizing roller 401 by the insertion ring 302, thereby improving the splicing and fit of the fastening roller 201, the synchronizing roller 401 and the buffer roller 301 and reducing the entry of impurities into the interior.

[0035] With the above structure, during use, when the short tooth group 6 or long tooth group 7 on the surface of the buffer roller 301 on the buffer mechanism 3 is caught by the crushed high-calcium stone block, the rotating fastening mechanism 2 and stabilizing mechanism 4 drive the first fixing plate 203 and the second fixing plate 303 to continue rotating. This causes the first fixing bolt 206 and the second fixing bolt 407 to pull the first storage spring 205 or the second storage spring 406, thereby stopping the short tooth group 6 and the long tooth group 7 on the buffer roller 301 from rotating. The buffer roller 301 uses short tooth group 6 and long tooth group 7 on its outer periphery to provide static buffering for the stones. At the same time, due to the jamming, the tension of the first storage spring 205 or the second storage spring 406 increases, thus continuing to crush and discharge the stones. This allows the first storage spring 205 or the second storage spring 406 to pull the buffer roller 301 to flip and reset, thus continuing the crushing process. This buffering and protection of the short tooth group 6 and long tooth group 7 improves the service life of the toothed roller.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
