Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for jaw crushers, specifically to an arc-shaped moving jaw body for a jaw crusher. Background Technology

[0002] Jaw crushers are mainly used for crushing large materials such as various ores, so that the material size meets the requirements for further crushing or grinding. Its main structure consists of a crushing chamber composed of a moving jaw plate and a stationary jaw plate, which can simulate the movement of an animal's jaws to achieve the crushing of materials.

[0003] The moving jaw plate and stationary jaw plate of a jaw crusher are in direct contact with the material. Under the high-speed movement of the moving jaw plate, the material is subjected to great compressive force and crushed, and the crushed material is discharged downward. The moving jaw plate and stationary jaw plate of the jaw crusher must not only resist the impact force, but also resist the huge friction force of the material on the surface of the jaw plate. Therefore, the jaw plates of the jaw crusher often need to be replaced due to wear, which not only brings a large maintenance cost, but also affects the production progress.

[0004] However, in the existing technology, specifically for the moving jaw of a crusher, the moving jaw plate is usually a single piece of structure. This means that when it is replaced later, the entire moving jaw plate needs to be replaced, which is costly. Moreover, the moving jaw plate is usually fixed by adding anchor bolts, which is not convenient to disassemble and assemble, making it time-consuming and laborious to replace later. Utility Model Content

[0005] The purpose of this utility model is to provide an arc-shaped moving jaw body for a jaw crusher in order to solve the above problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention provides an arc-shaped moving jaw body for a jaw crusher, including a moving jaw body, the front part of which is covered and fixed with a fixed base, and the front of the fixed base has multiple rows of mounting grooves.

[0008] In front of each row of mounting slots, there are multiple jaw crushers with closely adjacent sides. Each jaw crusher has a mating seat fixed horizontally on its back. Each jaw crusher is assembled in the corresponding row of mounting slots by sliding horizontally into the mounting slot through the mating seat.

[0009] Both ends of the mounting slot can be detachably combined with blocking and limiting components to restrict the mating seat within the corresponding mounting slot and prevent it from moving.

[0010] Preferably, the back of the moving jaw body is an arc-shaped surface.

[0011] Preferably, the fixing base is fixed to the front of the moving jaw body by anchoring, and both sides of the fixing base extend beyond the sides of the moving jaw body.

[0012] Preferably, the upper and lower jaw plates are closely adjacent to each other, and the front of the jaw plates is evenly distributed with jaw ribs to increase the jaw crushing force.

[0013] Preferably, the lateral length of the mating seat is consistent with the lateral length of the jaw crusher, and both end faces of the mating seat are flush with the corresponding end faces of the jaw crusher.

[0014] Preferably, the mounting groove is one of a dovetail groove, an I-shaped groove, or a T-shaped groove.

[0015] Preferably, each of the blocking and limiting components includes a blocking end block and a locking bolt. The blocking end blocks are provided at both ends of the mounting groove in a lateral sliding fit, and each blocking end block is closely adjacent to the mating seat on the corresponding side. The back of the fixed base has mating holes longitudinally formed on the portion extending beyond the outer side of the moving jaw body, and each mating hole is a through hole. The back of each blocking end block has locking holes longitudinally formed on the back, and each locking hole is longitudinally coaxial with the corresponding mating hole. The number of locking bolts corresponds to the number of mating holes, and each locking bolt passes coaxially from the rear end through the corresponding mating hole and enters the locking hole.

[0016] Preferably, the mating hole is a threaded through hole, the locking hole is a threaded blind hole, and the locking bolt is coaxially and detachably assembled with the corresponding mating hole and the locking hole through threaded engagement.

[0017] Preferably, the locking bolt is an external hexagonal bolt, and the portion of the locking bolt extending beyond the rear end of the mating hole is coaxially and slidably fitted with an anti-loosening washer. When the end of the locking bolt presses against the anti-loosening washer, the inner end of the locking bolt does not contact the bottom of the locking hole.

[0018] Preferably, the end faces of the blocking end blocks on both sides that are far apart from each other are provided with force-applying grooves to facilitate pulling and pushing.

[0019] In the above-mentioned arc-shaped moving jaw body of a jaw crusher, specifically in the actual use of the moving jaw body, after the fixed base is anchored to the front of the moving jaw body, multiple rows of mounting grooves are opened on the front of the fixed base. Then, through the lateral sliding engagement between the mating seat on the back of the jaw plate and the mounting groove, multiple jaw plates arranged side-by-side can be combined in each row of mounting grooves. This facilitates the individual replacement of the jaw plates at corresponding positions based on actual wear, reducing replacement costs. Furthermore, because the blocking end block laterally slides into the mounting groove and the locking bolt passes longitudinally coaxially through the mating hole and the locking hole, the blocking end block can limit and stop the mating seat in the corresponding row. The stop is fixed in the mounting groove and cannot move, thus allowing the corresponding row of jaw crushers to be detachably assembled in the mounting groove. The limiting and fixing method of the jaw crusher in front of the mounting groove is simple and easy to implement, making it convenient to assemble multiple jaw crushers in the corresponding row of the mounting groove for use. Furthermore, since the stop end block can be laterally slid out of the mounting groove after the locking bolt is removed, the corresponding row of multiple jaw crushers can be disassembled in sequence by moving the mating seat laterally along the mounting groove from the end. The method of removing the jaw crusher in front of the mounting groove is simple and easy to implement, making it convenient to replace multiple jaw crushers in the corresponding row of the mounting groove after they are disassembled in sequence or to change the arrangement order according to the actual wear condition.

[0020] The beneficial effects are as follows: 1. After the fixed base is anchored and fixed to the front of the moving jaw body, multiple rows of mounting grooves are opened on the front of the fixed base. Then, by means of the lateral sliding cooperation between the mating seat on the back of the jaw plate and the mounting groove, multiple jaw plates can be arranged side by side in the mounting grooves of each row. This makes it convenient to replace the jaw plates at the corresponding positions individually according to the actual wear condition, thus reducing the replacement cost.

[0021] 2. By using the blocking end block to slide laterally with the mounting groove and the locking bolt to pass longitudinally coaxially through the mating hole and the locking hole, the mating seat of the corresponding row can be limited and fixed in the mounting groove by the blocking end block, so that the jaw plates of the corresponding row can be detachably assembled in the mounting groove. The limiting and fixing method of the jaw plates in front of the mounting groove is simple and easy to implement, and it is convenient to combine multiple jaw plates in the mounting groove of the corresponding row for use.

[0022] 3. After simply removing the locking bolts, the blocking end block can slide out of the mounting slot. Then, by moving the mating seat laterally along the mounting slot from the end, multiple jaw plates in the corresponding row can be removed one by one. The method of removing the jaw plates in front of the mounting slot is simple and easy to achieve, which facilitates the subsequent replacement of multiple jaw plates after they are removed from the mounting slot of the corresponding row, or the arrangement order can be changed according to the actual wear condition.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] See Figures 1-7 As shown, this utility model provides an arc-shaped moving jaw body for a jaw crusher, including a moving jaw body 1. A fixed base 2 is fixedly covered on the front of the moving jaw body 1, and multiple rows of mounting grooves 201 are opened on the front of the fixed base 2. Multiple jaw crushing plates 3 with closely adjacent sides are arranged side by side in front of each row of mounting grooves 201. A mating seat 302 is horizontally fixed on the back of each jaw crushing plate 3, and the jaw crushing plates 3 are combined in the corresponding row of mounting grooves 201 by sliding the mating seat 302 horizontally into the mounting groove 201. The purpose of this arrangement is that multiple jaw crushing plates 3 arranged side by side can be combined in each row of mounting grooves 201 by the horizontal sliding engagement between the mating seat 302 on the back of the jaw crushing plate 3 and the mounting groove 201, which facilitates the individual replacement of the jaw crushing plates 3 at the corresponding positions according to the actual wear.

[0035] See Figures 1-5As shown, both ends of the mounting groove 201 can be detachably assembled with blocking and limiting components 4 to restrict the mating seat 302 within the corresponding mounting groove 201 and prevent it from moving. Specifically, each blocking and limiting component 4 includes a blocking end block 401 and a locking bolt 403. Both ends of the mounting groove 201 are provided with blocking end blocks 401 in a transverse sliding fit, and each blocking end block 401 is closely adjacent to the mating seat 302 on the corresponding side. The back of the fixed base 2, on the portion extending beyond the outer side of the moving jaw body 1, has longitudinally formed mating holes 405, and all mating holes 405 are through holes. The back of each blocking end block 401 has longitudinally formed locking holes 406, and each locking hole 406 is longitudinally coaxial with the corresponding mating hole 405. The number of locking bolts 403 corresponds to the number of mating holes 405, and the number of locking bolts 403 is... All of them pass coaxially from the rear end through the corresponding mating hole 405 and into the locking hole 406. The purpose of this setting is that, by using the blocking end block 401 to slide laterally with the mounting groove 201 and the locking bolt 403 to pass longitudinally coaxially through the mating hole 405 and the locking hole 406, the blocking end block 401 can limit and fix the mating seat 302 of the corresponding row in the mounting groove 201 so that it cannot move. In this way, the jaw crusher 3 of the corresponding row can be detachably assembled in the mounting groove 201. At the same time, by simply removing the locking bolt 403, the blocking end block 401 can slide out of the mounting groove 201. Then, by moving the mating seat 302 laterally along the mounting groove 201 from the end, the multiple jaw crushers 3 of the corresponding row can be removed one by one. The method of removing the jaw crusher 3 in front of the mounting groove 201 is simple and easy to achieve.

[0036] See Figures 1-7 As shown, the moving jaw body 1, the crushing jaw plate 3, and the blocking and limiting assembly 4 have been optimized as follows: Specifically, the back of the moving jaw body 1 is an arc-shaped surface, which allows the arc-shaped design of the back of the moving jaw body 1 to adapt to the internal space of the jaw crusher, and also helps to reduce stress concentration at the corners by using the arc-shaped design. Furthermore, the fixed base 2 is fixed to the front of the moving jaw body 1 by anchoring, and both sides of the fixed base 2 extend beyond the sides of the moving jaw body 1. This arrangement firstly facilitates the stable fixing of the fixed base 2 to the front of the moving jaw body 1, and secondly, ensures that the fixed base 2 has sufficient dimensions to allow for the easy installation of locking bolts 403 at the rear. Furthermore, the upper and lower jaw plates 3 are closely adjacent to each other, and the front of the jaw plates 3 is evenly distributed with jaw ribs 301 to increase the jaw crushing force. Preferably, the jaw ribs 301 are arc-shaped ribs arranged in the transverse direction, and the multiple jaw ribs 301 of the jaw plates 3 are evenly arranged in the vertical direction so as to enhance the jaw crushing force of the jaw plates 3 with the help of the jaw ribs 301. At the same time, there are cases where the gap between adjacent jaw plates 3 is too large and there is random movement and displacement during use.

[0037] See Figures 1-7 As shown, the lateral length of the mating seat 302 is consistent with the lateral length of the jaw crusher plate 3, and both end faces of the mating seat 302 are flush with the corresponding end faces of the jaw crusher plate 3. This arrangement ensures that after adjacent jaw crusher plates 3 are in close contact with each other, adjacent mating seats 302 can also be in close contact with each other to prevent random movement. Optionally, the mounting groove 201 can be a dovetail groove, an I-shaped groove, or a T-shaped groove, so that the mating seat 302 can only slide laterally along the mounting groove 201 and cannot be dislodged from other directions. The mating hole 405 is a threaded through hole, and the locking holes 406 are threaded blind holes. The locking bolt 403 is coaxially and detachably assembled with the corresponding mating hole 405 and locking hole 406 through threaded engagement. This arrangement facilitates quick assembly and disassembly of the locking bolt 403 with the mating hole 405 and locking hole 406 by tightening. Optionally, the locking bolt 403 is an external hexagonal bolt. The portion of the locking bolt 403 extending beyond the rear end of the mating hole 405 is coaxially fitted with an anti-loosening washer 404. When the end of the locking bolt 403 presses against the anti-loosening washer 404, the inner end of the locking bolt 403 does not contact the bottom of the locking hole 406. This design facilitates the anti-loosening effect of the locking bolt 403 by pressing the anti-loosening washer 404, and also allows for tightening of the locking bolt 403 using tools such as a torque wrench. Furthermore, the obstructing end blocks 401 on both sides have force-applying grooves 402 on their far-away end faces to facilitate pulling and pushing. Preferably, the force-applying grooves 402 are rectangular recesses with iron rods welded between the two sides. This design allows for easy pulling or pushing of the obstructing end blocks 401 into the mounting groove 201 by hooking onto the force-applying grooves 402.

[0038] Using the above structure, specifically in the actual use of the moving jaw body 1, after the fixed base 2 is anchored to the front of the moving jaw body 1, since the front of the fixed base 2 has multiple rows of mounting grooves 201, multiple jaw crushers 3 can be arranged side by side in the mounting grooves 201 by the lateral sliding engagement between the mating seat 302 on the back of the jaw crusher 3 and the mounting groove 201. This facilitates the individual replacement of the jaw crusher 3 at the corresponding position according to the actual wear condition, reducing replacement costs. Furthermore, by the lateral sliding engagement between the blocking end block 401 and the mounting groove 201 and the longitudinal coaxial passage of the locking bolt 403 through the mating hole 405 and the locking hole 406, the blocking end block 401 can limit and fix the mating seat 302 of the corresponding row in the mounting groove 201. The jaw plates 3 cannot move within the mounting slot 201, allowing for the detachable assembly of the corresponding row of jaw plates 3 within the mounting slot 201. The limiting and fixing method of the jaw plates 3 in front of the mounting slot 201 is simple and easy to implement, facilitating the sequential assembly of multiple jaw plates 3 into the corresponding row of mounting slots 201 for use. Furthermore, since the blocking end block 401 can be laterally slid out of the mounting slot 201 after removing the locking bolt 403, the multiple jaw plates 3 in the corresponding row can be sequentially removed by moving the mating seat 302 laterally along the mounting slot 201 from the end. The method of removing the jaw plates 3 in front of the mounting slot 201 is simple and easy to implement, facilitating the subsequent replacement of multiple jaw plates 3 after sequentially removing them from the corresponding row of mounting slots 201 or adjusting their arrangement order according to actual wear conditions.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
