Description
Technical Field
[0001] The utility model belongs to the technical field of swing tooth plates, and in particular relates to a high-strength composite swing tooth plate. Background Art
[0002] Jaw crusher is a commonly used crushing equipment. Its core structure consists of two jaw plates, the movable jaw and the static jaw, forming a crushing chamber, which simulates the movement of the two jaws of an animal to complete the material crushing operation. Its working principle is mainly to crush materials through the periodic movement of the movable jaw. In the process of the movable jaw swinging around the suspension mandrel to the fixed jaw, the material is subjected to a comprehensive effect of crushing, splitting and bending, thereby achieving crushing. In the prior art, the swinging tooth plate on the movable jaw plate of the Russian crusher needs to withstand a strong impact force when in use, and there is a lack of a buffer structure between the two. Therefore, the possibility of structural damage during the crushing process is high, resulting in a short service life of the tooth plate. Utility Model Content
[0003] In view of the above problems, the purpose of the utility model is to provide a high-strength composite swing tooth plate, and the rubber support blocks and rubber pads set therein can play a buffering role in the process of transmitting the impact force generated by the collision between the tooth plate and the material during crushing, thereby reducing the possibility of structural damage to the device caused by the impact force.
[0004] To achieve the above objectives, the utility model provides the following technical solutions: a high-strength composite swinging gear plate comprises a movable jaw plate, one side of the movable jaw plate is provided with a first embedding groove inwardly, the side of the movable jaw plate is provided with a first screw hole, one side of the movable jaw plate is provided with a gear plate fixing base plate, one side of the gear plate fixing base plate is provided with an integrally formed first embedding strip, the first embedding strip and the first embedding groove are embedded and connected, one side of the gear plate fixing base plate and the outer side of the first embedding strip are provided with a rubber pad, one side of the gear plate fixing base plate is provided with a weight reduction groove inwardly, and a rubber support block is also provided inside the weight reduction groove, a second screw hole is penetrated between the two side surfaces of the gear plate fixing base plate, a second embedding groove is provided on one side of the gear plate fixing base plate, a gear plate is provided on one side of the gear plate fixing base plate, a second embedding strip is provided on one side of the gear plate, the second embedding strip is embedded and connected between the second embedding strip and the second embedding groove, an upper rack and a lower rack are provided on the other side of the gear plate, and a countersunk screw hole is penetrated between the left and right sides of the gear plate.
[0005] The beneficial effects of the utility model are as follows: when the device is performing crushing work, the movable jaw plate swings under the drive of the jaw crusher driving mechanism, driving the tooth plate fixed base plate and the tooth plate together, and the upper rack, the lower rack and the tooth plate on the fixed jaw plate cooperate to crush the material. During the crushing process, the first embedded strip and the second embedded strip not only play a role in assisting the tooth plate fixed base plate and the tooth plate to fix, but also play a role in strengthening the structural strength of the two. The rubber support block is arranged in a partition groove separated by reinforcing ribs in the weight reduction groove, and the side surfaces on both sides are in contact with the weight reduction groove and the movable jaw plate respectively, and the rubber pad is directly spaced between the tooth plate fixed base plate and the movable jaw plate. Therefore, the rubber support block and the rubber pad can play a buffering role in the process of transmitting the impact force generated by the collision between the tooth plate and the material during crushing, thereby reducing the possibility of structural damage to the device caused by the impact force.
[0006] Since the lower part of the tooth plate is generally more severely worn than the upper part during use, we set the upper rack to an arc shape and the lower rack to a trapezoidal quadrangular prism shape. The thickness of the upper rack gradually increases from lower than the lower rack to the same as the lower rack, so that the thickness of the rack from top to bottom is proportional to the wear. The tooth plate of this device has a lower thickness, and the tooth plate is fixed and structurally supported and reinforced by a non-disposable tooth plate fixing base plate fixed on the movable jaw plate, thereby reducing the overall material consumption required to produce the tooth plate, thereby reducing production costs.
[0007] In order to strengthen the structural strength of the tooth plate fixing base plate:
[0008] As a further improvement of the above technical solution: reinforcing ribs are provided on the inner side of the weight-reducing groove.
[0009] The beneficial effect of this improvement is that the reinforcing ribs are used to strengthen the structural strength of the tooth plate fixing base plate.

[0012] The beneficial effect of this improvement is that the first screw hole, the second screw hole and the countersunk screw hole are connected by the first bolt, so as to fix the tooth plate fixing base plate, the tooth plate and the movable jaw plate.
[0013] In order to fix the movable jaw plate and the tooth plate fixed base plate:
[0014] As a further improvement of the above technical solution: the movable jaw plate and the tooth plate fixed base plate are connected by a second bolt.
[0015] The beneficial effect of this improvement is that the movable jaw plate and the tooth plate fixed base plate are connected by the second bolt, thereby fixing the movable jaw plate and the tooth plate fixed base plate.
[0016] In order to strengthen the tooth plate fixing base and the tooth plate:
[0017] As a further improvement of the above technical solution: an upper reinforcement plate and a lower reinforcement plate are provided on one side of the tooth plate fixing base plate, and reinforcement slots are provided on the top and bottom of the tooth plate. The upper reinforcement plate and the reinforcement slot, as well as the lower reinforcement plate and the reinforcement slot are inserted and connected, and the thickness of the upper reinforcement plate gradually increases from lower than the lower reinforcement plate to the same as the lower reinforcement plate from top to bottom.
[0018] The beneficial effect of this improvement is that the upper reinforcement plate and the reinforcement slot, as well as the lower reinforcement plate and the reinforcement slot are inserted and connected, which has the effect of mutual cooperation and limitation, thereby playing a role in reinforcing the tooth plate fixing base and the tooth plate.

The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.
[0029] like Figure 1-7 As shown, a high-strength composite swing tooth plate comprises a movable jaw plate 1, a first embedding groove 2 is opened inwardly on one side of the movable jaw plate 1, a first screw hole 3 is provided on the side of the movable jaw plate 1, a tooth plate fixing base plate 4 is provided on one side of the movable jaw plate 1, a first integrally formed embedding strip 5 is provided on one side of the tooth plate fixing base plate 4, the first embedding strip 5 and the first embedding groove 2 are embedded and connected, a rubber pad 6 is provided on one side of the tooth plate fixing base plate 4 together with the outer side of the first embedding strip 5, a weight-reducing groove 7 is opened inwardly on one side of the tooth plate fixing base plate 4, and the weight-reducing groove 7 A rubber support block 9 is also provided inside, a second screw hole 10 is penetrated between the side surfaces of the toothed plate fixing base plate 4, a second embedding groove 11 is provided on one side of the toothed plate fixing base plate 4, a toothed plate 12 is provided on one side of the toothed plate fixing base plate 4, an integrally formed second embedding strip 13 is provided on one side of the toothed plate 12, the second embedding strip 13 and the second embedding groove 11 are embedded and connected, an upper rack 14 and a lower rack 15 are provided on the other side of the toothed plate 12, and a countersunk screw hole 16 is penetrated between the left and right sides of the toothed plate 12.
[0030] When the device is performing crushing work, the movable jaw plate 1 swings under the drive of the jaw crusher driving mechanism, driving the tooth plate fixed base plate 4 and the tooth plate 12 together, and the upper rack 14, the lower rack 15 and the tooth plate on the fixed jaw plate cooperate to crush the material. During the crushing process, the first embedded strip 5 and the second embedded strip 13 not only play a role in assisting the tooth plate fixed base plate 4 and the tooth plate 12 to be fixed, but also play a role in strengthening the structural strength of the two. The rubber support block 9 is arranged in the partition groove separated by the reinforcing rib 8 in the weight reduction groove 7, and the side surfaces on both sides are in contact with the weight reduction groove 7 and the movable jaw plate 1 respectively, and the rubber pad 6 is directly spaced between the tooth plate fixed base plate 4 and the movable jaw plate 1. Therefore, the rubber support block 9 and the rubber pad 6 can play a buffering role in the process of transmitting the impact force generated by the collision between the tooth plate 12 and the material during crushing, thereby reducing the possibility of structural damage to the device caused by the impact force.
[0031] Since the lower half of the tooth plate is generally more severely worn than the upper half during use, we set the upper rack 14 to an arc shape and the lower rack 15 to a trapezoidal quadrangular prism shape. The thickness of the upper rack 14 gradually increases from top to bottom from lower than the lower rack 15 to the same as the lower rack 15, so that the thickness of the rack from top to bottom is proportional to the wear. The tooth plate 12 of the device has a lower thickness, and the tooth plate 12 is fixed and structurally supported and reinforced by a non-disposable tooth plate fixing base plate 4 fixed on the movable jaw plate 1, thereby reducing the overall material consumption required for the production of the tooth plate, thereby reducing the production cost.
[0032] A reinforcing rib 8 is provided on the inner side of the weight-reducing groove 7 .
[0033] The reinforcing ribs 8 are used to strengthen the structural strength of the tooth plate fixing base plate 4 .
[0034] The first screw hole 3 , the second screw hole 10 , and the countersunk screw hole 16 are connected by a first bolt 20 .
[0035] The first screw hole 3 , the second screw hole 10 , and the countersunk screw hole 16 are connected by a first bolt 20 , so as to fix the tooth plate fixing base plate 4 , the tooth plate 12 , and the movable jaw plate 1 .
[0036] The movable jaw plate 1 and the tooth plate fixed base plate 4 are connected by a second bolt 21 .
[0037] The movable jaw plate 1 and the tooth plate fixing base plate 4 are connected by the second bolts 21 , so as to fix the movable jaw plate 1 and the tooth plate fixing base plate 4 .
[0038] An upper reinforcement plate 17 and a lower reinforcement plate 18 are provided on one side of the tooth plate fixing base plate 4, and reinforcement slots 19 are provided on the top and bottom of the tooth plate 12. The upper reinforcement plate 17 and the reinforcement slot 19, and the lower reinforcement plate 18 and the reinforcement slot 19 are inserted and connected. The thickness of the upper reinforcement plate 17 gradually increases from lower than the lower reinforcement plate 18 to the same as the lower reinforcement plate 18 from top to bottom.
[0039] The upper reinforcing plate 17 and the reinforcing slot 19 as well as the lower reinforcing plate 18 and the reinforcing slot 19 are inserted and connected to cooperate with each other to limit the position, thereby reinforcing the tooth plate fixing base plate 4 and the tooth plate 12 .
[0040] Working principle and use process of the utility model: when the device is performing crushing work, the movable jaw plate 1 swings under the drive of the jaw crusher driving mechanism, driving the tooth plate fixed base plate 4 and the tooth plate 12 together, and the upper rack 14, the lower rack 15 and the tooth plate on the fixed jaw plate cooperate to crush the material. During the crushing process, the first embedded strip 5 and the second embedded strip 13 not only play a role in assisting the tooth plate fixed base plate 4 and the tooth plate 12 to be fixed, but also play a role in strengthening the structural strength of the two. The rubber support block 9 is arranged in the partition groove separated by the reinforcing ribs 8 in the weight reduction groove 7, and the side surfaces on both sides are in contact with the weight reduction groove 7 and the movable jaw plate 1 respectively, and the rubber pad 6 is directly spaced between the tooth plate fixed base plate 4 and the movable jaw plate 1, so the rubber support block 9 and the rubber pad 6 can be in the process of transmitting the impact force generated by the collision between the tooth plate 12 and the material during crushing. It plays a buffering role in reducing the possibility of structural damage to the device caused by impact force. Since the wear of the lower part is generally more serious than that of the upper part during the use of the tooth plate, we set the upper rack 14 to an arc shape and the lower rack 15 to a trapezoidal quadrangular prism shape. The thickness of the upper rack 14 gradually increases from lower than the lower rack 15 to the same as the lower rack 15 from top to bottom, so that the thickness of the rack from top to bottom is proportional to the wear. The traditional one-piece tooth plate is generally designed to be thicker for the structural strength of the tooth plate and the stability of installation on the movable jaw plate 1. The tooth plate 12 of the device is thinner, and the tooth plate 12 is fixed and structurally supported and reinforced by a non-disposable tooth plate fixing base plate 4 fixed on the movable jaw plate 1, thereby reducing the overall material consumption required for the production of the tooth plate, thereby reducing the production cost.
