Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to an impact plate adjustment device and an impact crusher. Background Art

[0002] In the impact crusher, the position adjustment of the impact plate directly affects the crushing particle size and capacity of the crusher. Therefore, during the debugging stage, the gap between the impact plates will be adjusted according to different feed and discharge particle sizes to maximize the capacity while ensuring the operation quality.

[0003] During use, the wear-resistant parts of the rotor and the impact plate will gradually wear out as the use time increases, causing the gap between the impact plates to gradually increase over time. When the gap between the impact plates increases to the point where it affects the crushing effect, the wear-resistant parts of the rotor and the impact plate need to be replaced, and the position of the impact plate needs to be readjusted.

[0004] At present, the adjustment device of the impact plate usually adopts manual and hydraulic auxiliary adjustment, that is, it needs hydraulic cylinder auxiliary adjustment, pre-pushing the impact plate, and then additional manpower adjustment. However, in this way, the adjustment device needs to match the hydraulic system, resulting in a more complicated device structure. In addition, it needs to rely on manual participation in adjustment, which affects the efficiency of debugging and maintenance, and the user experience is poor. Utility Model Content

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Combine the following Figures 1 to 5 The impact plate adjustment device of some embodiments of the utility model is described.

[0041] like Figures 1 to 5 As shown, the embodiment of the utility model provides a counter-attack plate adjustment device, including a mounting frame 1, an adjustment member 2, a worm wheel 3, a worm 4 and a motor 5. Specifically, as Figure 1 As shown, the mounting frame 1 is used to connect with the housing 16 of the impact crusher. Figure 3 As shown, the mounting frame 1 can be equipped with a mounting plate, which can be fixedly connected to the housing 16 by a bolt assembly, so as to facilitate disassembly and assembly. The adjusting member 2 is provided through the mounting frame 1 and the housing 16, and the adjusting member 2 is slidably connected to the mounting frame 1 and the housing 16. The adjusting member 2 is used to be connected to the impact plate 17 of the impact crusher to drive the impact plate 17 to rotate, adjust the position of the impact plate 17, and then adjust the gap between the impact plates. The motor 5 is used to drive the adjusting member 2 to move, and the output end of the motor 5 is connected to the adjusting member 2 through a transmission mechanism.

[0042] Such a configuration uses a motor 5 to drive, has a simple structure, does not require an additional matching hydraulic system, and eliminates the problems caused by the traditional use of hydraulic cylinders. At the same time, the transmission mechanism drives the adjustment member to move, so that the counter-attack plate 17 can be automatically adjusted, which is convenient to operate and does not require additional manpower to participate in the adjustment, saving time and effort, and improving the debugging and maintenance efficiency.

[0043] In some embodiments of the present invention, the impact plate adjustment device further includes a suspension beam 6, a guide member 7, an elastic member 8, and a stop member 9. Specifically, Figure 4 As shown, the suspension beam 6 is connected to the adjustment member 2, and the adjustment member 2 can rotate relative to the suspension beam 6. Specifically, the adjustment member 2 can be connected to the suspension beam 6 through a bearing, so that the two can move synchronously and the adjustment member 2 can rotate. The guide member 7 is fixedly connected to the housing 16. For example, the guide member 7 can be a guide rod, and its end is provided with an external thread, and the guide rod can be fixed to the housing 16 by a nut. The guide member 7 is arranged along the axial direction of the adjustment member 2, and the guide member 7 passes through the suspension beam 6, and the guide member 7 is slidably connected to the suspension beam 6. The elastic member 8 can be a spring, and the spring is sleeved on the guide member 7. The limit member 9 can be a limit plate, and the limit plate is arranged at one end of the guide member 7 away from the impact plate 17. The limit member 9 is used to limit the displacement of the suspension beam 6. One end of the elastic member 8 abuts against the suspension beam 6, and the other end abuts against the limit member 9.

[0044] With such a configuration, when the impact on the impact plate 17 is too great, the impact plate 17 will drive the adjustment member 2 and the suspension beam 6 to move along the axial direction of the guide member 7 as a whole, close to the limit member 9, at which time the elastic member 8 will be deformed. The elastic force of the elastic member 8 can be used to buffer and reset, ensuring the stability of the working position of the impact plate 17, preventing the equipment from being overloaded and causing damage to the crushing host, and improving the reliability of the equipment and ensuring the service life of the device. It should be noted that, with the following configuration, Figure 4 As for the placement position of the impact plate adjustment device shown in the figure, the up and down directions in the figure are the axial directions of the adjustment member 2 and the guide member 7.

[0045] In some embodiments of the present invention, Figure 2 As shown, the guide member 7 passes through the limit member 9, and the limit member 9 is slidably connected to the guide member 7. The impact plate adjustment device also includes at least two locking members 10, which are threadedly connected to the guide member 7, and locking members 10 are respectively provided on both sides of the limit member 9. Specifically, the locking member 10 can use a locking nut, and the end of the guide member 7 is provided with an external thread that matches the locking nut. In this way, the position of the limit member 9 can be adjusted according to actual use requirements. After it is adjusted into place, it is fixed by the locking nuts on both sides to limit the position of the limit member 9. In addition, double nut locking can be used to ensure reliable locking. With this arrangement, the position of the limit member 9 can be adjusted to meet different use requirements. In addition, if Figure 2 As shown, the upper end of the elastic member 8 is sleeved outside the locking member 10, so a sleeve 18 can be arranged between the lower end of the elastic member 8 and the outer wall of the guide member 7 to ensure that the elastic member 8 and the guide member 7 are reliably matched and prevent the elastic member 8 from twisting during the deformation process. The sleeve 18 is fixedly connected to the suspension beam 6, and the sleeve 18 is sleeved on the guide member 7, and the sleeve 18 and the guide member 7 are slidably matched.

[0046] In some embodiments of the present invention, the number of guide members 7 is at least two, and each guide member 7 is spaced apart along the circumference of the adjusting member 2, and the elastic member 8 is disposed one by one with the guide member 7. Figure 3 As shown, the number of guide members 7 and elastic members 8 are both two, which are symmetrically distributed on both sides of the adjusting member 2, so as to better play the role of guiding and buffering reset. In addition, each guide member 7 can share a limit member 9 and be fixed by a locking member 10.

[0047] Since the counter-attack plate 17 is swing-adjustable, it cannot be ensured that the adjusting member 2 is always perpendicular to the mounting plane of the housing 16. Therefore, in some embodiments of the present invention, the counter-attack plate adjusting device further includes an elastic pad assembly 11, such as Figure 2 As shown, the elastic pad assembly 11 is sleeved on the adjustment member 2, and the elastic pad assembly 11 is arranged between the suspension beam 6 and the mounting frame 1. Specifically, the elastic pad assembly 11 may include a pair of flat washers and an elastic washers, and the elastic washers are located between the pair of flat washers. In this way, the deformation of the elastic pad assembly 11 can be used to adapt to different angle changes, so that the mounting frame 1 and the suspension beam 6 are always in close contact through the elastic pad assembly 11. Of course, the elastic pad assembly 11 is not limited to the above-mentioned combination form, and other structures with elastic deformation capabilities such as rubber pads and rubber springs can also be used.

[0048] In some embodiments of the present invention, the transmission mechanism includes a meshing worm wheel 3 and a worm 4. Specifically, Figure 2 As shown, the adjusting member 2 is provided with an external thread section, and the worm wheel 3 is provided with a threaded hole adapted to the external thread section. The adjusting member 2 is rotatably arranged in the threaded hole, and the adjusting member 2 moves along the axial direction of the worm wheel 3. Specifically, the worm wheel 3 and the adjusting member 2 can be connected by T-type thread matching, which has good transmission performance and is not easy to loosen. The output end of the motor 5 is connected to the worm 4 in a transmission manner, so that the motor 5 can drive the worm 4 to rotate. For example, the motor 5 can be a servo motor. It should be noted that, as shown in FIG. Figure 2 As for the placement position of the impact plate adjustment device shown in the figure, the up and down direction in the figure is the axial direction of the worm gear 3.

[0049] With such a configuration, the impact plate 17 can be automatically adjusted by the motor 5 in cooperation with the worm gear transmission mechanism, which is easy to operate and does not require additional human intervention. Moreover, when the crusher is working, the impact plate 17 will be displaced by impact. Since the worm gear transmission mechanism has good self-locking performance, it can ensure that the motor 5 will not rotate due to force, thereby ensuring the stability of the impact plate 17 position in the operating state and improving the reliability of the equipment.

[0050] In some embodiments of the present invention, the impact plate adjustment device further includes a driving gear 12 and a driven gear 13. Figure 4 As shown, the driving gear 12 is connected to the output end of the motor 5, for example, the output shaft of the motor 5 is connected to the driving gear 12 via a key. The driven gear 13 is meshed with the driving gear 12, and the driven gear 13 is connected to the worm 4. For example, the worm 4 and the driven gear 13 are connected via a key, or the two can be integrally formed.

[0051] With this arrangement, during adjustment, the motor 5 rotates forward / reverse, driving the driving gear 12 to rotate synchronously, the driving gear 12 drives the driven gear 13 to rotate, the worm 4 and the driven gear 13 rotate together, and then the worm 4 drives the worm wheel 3 to rotate. When the worm wheel 3 rotates, the adjusting member 2 rotates accordingly and moves along the axial direction of the worm wheel 3, thereby driving the impact plate 17 to swing. Moreover, through the gear transmission mechanism, speed reduction, speed matching, etc. can be achieved to meet the adjustment requirements of the impact plate 17.

[0052] In some embodiments of the present invention, the counter-plate adjustment device further includes a protective cover 14, specifically, as Figure 5 As shown, the protective cover 14 is fixedly connected to the suspension beam 6. The protective cover 14 is arranged outside the driving gear 12 and the driven gear 13, and the worm wheel 3 and the worm 4 are located in the protective cover 14. Therefore, the protective cover 14 can protect the transmission mechanism, avoid the intrusion of dust and other impurities, ensure the reliable operation of the device, and extend the service life of the device. In addition, Figure 3 As shown, the adjusting member 2 can penetrate the protective cover 14. The motor 5 can be installed outside the protective cover 14, and its output shaft penetrates into the protective cover 14 and is connected to the driving gear 12.

[0053] In some embodiments of the present invention, Figure 2 As shown, a limiting space 15 adapted to the worm wheel 3 is provided in the protective cover 14, and the limiting space 15 is used to prevent the worm wheel 3 from moving along the axial direction of the adjusting member 2. Thus, the displacement of the worm wheel 3 in the up and down directions is limited by the limiting space 15, so as to ensure that the adjusting member 2 works reliably, and the structure is simple and the operation is convenient. Figure 2 For the placement position of the impact plate adjustment device shown in the figure, the up and down directions in the figure are the upper and lower positions referred to.

[0054] In some embodiments of the present invention, the adjusting member 2 is hinged to the counter-attack plate 17. For example, the adjusting member 2 can be an adjusting screw. Figure 3As shown, an n-shaped hinge seat 19 is provided at the end of the adjusting member 2. The counter-plate 17 extends into the opening of the hinge seat 19, and the hinge seat 19 and the counter-plate 17 are provided with hinge holes for the pins 20 to pass through. The pins 20 pass through the hinge holes in sequence to rotatably connect the adjusting member 2 and the counter-plate 17. Such a configuration can ensure that the adjusting member 2 can drive the counter-plate 17 to swing flexibly, which is convenient for operation. In addition, in order to prevent the pin 20 from falling off, stoppers such as pins, bolts and nuts can be inserted at both ends of the pin 20.

[0055] The impact crusher provided by the utility model is described below. The impact crusher described below and the impact plate adjustment device described above can be referred to each other.

[0056] The present utility model also provides an impact crusher, including the impact plate adjustment device in the above-mentioned embodiments. Figure 1 As shown, the impact crusher includes a shell 16 and an impact plate 17. The impact plate 17 is hinged to the inner wall of the shell 16 through a rotating shaft, and the gap between the impact plate 17 and the rotor can be adjusted by an impact plate adjustment device. In addition, the impact plate 17 may include a primary impact plate and a secondary impact plate, and the primary impact plate and the secondary impact plate are respectively provided with an impact plate adjustment device. With such a configuration, the motor 5 is used for driving, the structure is simple, and there is no need to match the hydraulic system, thereby eliminating the problems caused by the traditional use of hydraulic cylinders for auxiliary adjustment. At the same time, the adjustment member is driven to move by the transmission mechanism, so that the impact plate 17 can be automatically adjusted, which is convenient to operate, does not require human intervention in the adjustment, saves time and effort, and improves the debugging and maintenance efficiency. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-mentioned impact plate adjustment device, so it will not be repeated here.
