Description

Technical Field

[0001] The utility model belongs to the technical field of impact crushers, and in particular relates to a crushing liner adjustment mechanism of an impact crusher. Background Art

[0002] The main purpose of setting the crushing liner adjustment mechanism of the impact crusher is to be able to quickly and conveniently adjust the position and angle of the impact plate according to different crushing requirements and material characteristics, so as to optimize the crushing efficiency and obtain better product particle shape.

[0003] The crushing liner adjustment of traditional impact crushers is often only equipped with manual adjustment of lead screws and spring screws. The position of the lead screw is adjusted by manually rotating the bolt or nut to adjust the position of the impact plate. The stability and anti-swing ability of the impact plate after adjustment are improved by the pre-tightening force of the spring screw. This method is simple to operate, but the adjustment speed is slow, the accuracy is not high, and manual operation is required, which is labor-intensive. When the distance between the impact plate and the rotor hammer needs to be adjusted quickly or frequently, this manual adjustment mechanism equipped with only lead screws and spring screws often increases the complexity of adjustment and affects the continuity and efficiency of production. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model proposes a crushing liner adjustment mechanism for an impact crusher.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A crushing liner adjustment mechanism of an impact crusher comprises a support plate located on a crusher housing and an adjustment frame located outside the support plate, an adjustment screw connected to the impact plate, two spring screws located on both sides of the adjustment screw and two hydraulic cylinders located on both sides of the two spring screws are arranged at the center of the support plate;

[0007] Pull the impact plate from the support plate by adjusting the screw rod to prevent the impact plate from falling;

[0008] The spring screw rod presses the adjustment frame onto the support plate and maintains the preload force adapted to the normal crushing force, so as to prevent the impact plate from swinging backwards when subjected to the normal crushing force;

[0009] The distance between the impact plate and the rotor hammer is adjusted by a hydraulic cylinder.

[0010] The coordinated use of the adjusting screw rod, spring screw rod and hydraulic cylinder can realize the position adjustment of the impact plate to meet the needs of different materials and crushing conditions.

[0011] Preferably, a fixing sleeve is provided at the end of the adjusting screw rod, and a U-shaped plate connected to the impact plate through a pin shaft is fixed at the end of the fixing sleeve. The end of the adjusting screw rod away from the fixing sleeve presses the shock-absorbing disc spring onto the support plate through an inner clamping nut and an outer clamping nut.

[0012] Preferably, an inner thread sleeve is provided above the outer clamping nut and is threadedly connected to the outside of the adjusting screw and limited above the adjusting frame. The inner thread sleeve is limited on the mounting block on the adjusting frame.

[0013] The coordinated use of the adjusting screw and nut makes the position adjustment of the impact plate more precise and convenient, and can quickly adapt to different crushing needs.

[0014] Preferably, one end of the spring screw is fixed on the support plate and the other end passes through the sleeve and the pressure plate on the adjusting frame and is threadedly connected to the pressure cap and the wire adjusting nut. A spring is sleeved on the spring screw between the sleeve and the adjusting frame. The sleeve and the pressure plate are pressed against the spring by screwing the pressure cap, so that the spring away from the end of the pressure plate presses the adjusting frame onto the support plate.

[0015] Preferably, the two spring screw rods share a pressing plate, and a relief opening is opened on the pressing plate to provide a space for the inner thread sleeve to be screwed.

[0016] By screwing the spring screw and the pressure cap, the position of the impact plate can be adjusted quickly and conveniently to meet different crushing requirements.

[0017] Preferably, the main body of the hydraulic cylinder is fixed on the adjustment plate, and the piston rod is connected to the support plate.

[0018] By applying pressure to the hydraulic cylinder, the piston rod will extend, pushing the adjustment plate to move relative to the support plate, thereby adjusting the position of the impact plate.

[0019] Compared with the prior art, the technical effects and advantages of the utility model are:

[0020] The adjusting screw of the crushing liner adjustment mechanism of the impact crusher is connected to the impact plate through a fixed sleeve and a U-shaped plate, and the U-shaped plate is connected to the impact plate through a pin shaft to form a rotatable joint. In this way, the position of the impact plate can be accurately adjusted by rotating the adjusting screw. Two spring screws are located on both sides of the adjusting screw and are connected to the shock-absorbing disc spring and the support plate through a clamping nut. The position of the adjusting nut can change the compression amount of the shock-absorbing disc spring, thereby affecting the position of the impact plate. The inner thread sleeve provides a limit reference point for adjustment to ensure that the position of the impact plate does not exceed the set range.

[0021] The two main parts of the hydraulic cylinder are fixed on the adjustment plate, and the piston rod part is connected to the support plate. By applying pressure to the hydraulic cylinder, the piston rod extends, pushing the adjustment plate to move relative to the support plate, thereby adjusting the position of the impact plate. The hydraulic cylinder provides an effective power source that can achieve fast and accurate position adjustment.

[0022] The pre-tightening design of the spring screw and the limiting function of the inner thread sleeve ensure the stability of the impact plate when subjected to crushing force, and avoid excessive swing of the impact plate under the impact force. The design of the support plate and the adjustment frame enables the adjustment mechanism to flexibly adjust around the impact plate. The coordinated use of the adjustment screw, spring screw and hydraulic cylinder makes the position adjustment of the impact plate more direct and efficient, and can meet the needs of different materials and crushing conditions.

[0023] The crushing liner adjustment mechanism of the impact crusher uses a variety of adjustment methods (such as rotating the adjustment screw, adjusting the compression of the spring screw, and using a hydraulic cylinder) to accurately control the position of the impact plate to adapt to different crushing requirements and material characteristics. At the same time, the mechanism also ensures the stability and safety of the impact plate during the crushing process through pre-tightening design and limit function, thereby improving the overall performance and reliability of the crusher.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0030] The following is combined with Figure 1-4 To further explain this application in detail,

[0031] The embodiment of the present application discloses a crushing liner adjustment mechanism of an impact crusher, comprising:

[0032] The support plate 1 is located on the shell of the crusher and an adjusting screw rod 3 connected to the impact plate is provided at the center of the support plate 1; the impact plate is pulled from the support plate 1 by adjusting the screw rod 3 so that the impact plate will not fall down;

[0033] Two spring screw rods 4 are provided and are located on both sides of the adjusting screw rod 3 and penetrate the support plate 1 and the adjusting frame 2;

[0034] A fixing sleeve 6 is provided at the end of the adjusting screw rod 3, and a U-shaped plate 7 connected to the impact plate through a pin shaft is fixed at the end of the fixing sleeve 6. The end of the adjusting screw rod 3 away from the fixing sleeve 6 presses the shock-absorbing disc spring 10 onto the support plate 1 through an inner clamping nut 8 and an outer clamping nut 9. An inner thread sleeve 11 is provided above the outer clamping nut 9 and is threadedly connected to the outside of the adjusting screw rod 3 and limited above the adjusting frame 2. The inner thread sleeve 11 is limited on the mounting block 12 on the adjusting frame 2.

[0035] The design of the fixed sleeve 6 and the U-shaped plate 7 allows the adjusting screw rod 3 to be connected to the impact plate through a pin shaft to form a rotatable joint, so that the impact plate can be adjusted relative to the adjusting screw rod 3; the two ends of the adjusting screw rod 3 are respectively connected to the shock-absorbing disc spring 10 and the support plate 1 through the inner clamping nut 8 and the outer clamping nut 9. By adjusting the position of these nuts, the compression amount of the shock-absorbing disc spring 10 can be changed, thereby affecting the position of the impact plate. The inner thread sleeve 11 is connected to the outside of the adjusting screw rod 3 through a threaded connection and is limited on the mounting block 12 above the adjusting frame 2. In this way, a limit reference point can be provided when adjusting the position of the impact plate to ensure that the position of the impact plate does not exceed the set range.

[0036] Through the design of the fixed sleeve 6 and the U-shaped plate 7, the impact plate can be easily connected or disconnected with the adjusting screw rod 3, which is convenient for maintenance and replacement. The coordinated use of the adjusting screw rod 3 and the nut makes the position adjustment of the impact plate more precise and convenient, and can quickly adapt to different crushing requirements. The limiting function of the inner thread sleeve 11 ensures that the position of the impact plate will not be over-adjusted, avoiding equipment damage or poor crushing effect due to improper position. This design can also provide a certain shock absorption effect, reducing the damage to the equipment caused by the impact force generated during the crushing process.

[0037] One end of the spring screw rod 4 is fixed on the support plate 1 and the other end passes through the sheath 13 and the pressure plate 14 on the adjusting frame 2 and is threadedly connected with the pressure cap 15 and the wire adjusting cap 16. A spring 17 is sleeved on the spring screw rod 4 between the sheath 13 and the adjusting frame 2. By screwing the pressure cap 15, the sheath 13 and the pressure plate 14 are pressed against the spring 17, so that the spring 17 at one end away from the pressure plate 14 presses the adjusting frame 2 on the support plate 1, and has a certain preload force to adapt to the normal crushing force, thereby ensuring that the entire impact plate will not swing backward when subjected to the normal crushing force; the two spring screw rods 4 share a pressure plate 14, and a avoidance opening 18 is opened on the pressure plate 14 to provide space for screwing the inner thread sleeve 11.

[0038] The design of the spring screw rod 4 allows the adjustment mechanism to compress the spring 17 by screwing the pressure cap 15. The spring 17 is sleeved on the spring screw rod 4 between the sheath 13 and the adjustment frame 2. By screwing the pressure plate 14 and the pressure cap 15, the spring 17 can press the adjustment frame 2 on the support plate 1, thereby achieving pre-tightening and stabilization of the position of the counter-attack plate. The design of two spring screw rods 4 sharing one pressure plate 14 can simplify the structure and save materials, while providing space for screwing the inner thread sleeve 11 for easy adjustment.

[0039] By screwing the spring screw 4 and the pressure cap 15, the position of the impact plate can be quickly and conveniently adjusted to meet different crushing requirements. The pre-tightening design of the spring screw 4 provides a certain stability and anti-swing ability to protect the stability of the impact plate when subjected to crushing force.

[0040] The design of two spring screw rods 4 sharing one pressure plate 14 can improve the reliability and service life of the adjustment mechanism while saving costs. The space design between the sheath 13 and the adjustment frame 2 can facilitate the adjustment operation and avoid restrictions and obstacles to the adjustment space.

[0041] Two hydraulic cylinders 5 are provided and located on both sides of the two spring screw rods 4. The main body of the hydraulic cylinder 5 is fixed on the adjustment plate, and the piston rod is connected to the support plate 1. The hydraulic cylinder 5 is used to adjust the distance between the impact plate and the rotor plate hammer.

[0042] The main body of the hydraulic cylinder 5 is fixed on the adjustment plate, which means that the position of the hydraulic cylinder 5 is fixed and will not move with the extension and retraction of the piston rod. The piston rod is connected to the support plate 1, so that the movement of the piston rod will be directly converted into the movement of the adjustment plate, thereby pushing the impact plate to be adjusted. By applying pressure to the hydraulic cylinder 5, the piston rod will extend, pushing the adjustment plate to move relative to the support plate 1, thereby adjusting the position of the impact plate.

[0043] The hydraulic cylinder 5 provides an effective power source and can achieve fast and accurate position adjustment. The movement of the piston rod and the adjustment plate is driven by the hydraulic cylinder 5, which can reduce mechanical wear and extend the service life of the equipment. Since the piston rod is directly connected to the support plate 1, the position adjustment of the impact plate is more direct and efficient. The hydraulic cylinder 5 can be easily integrated into the control system of the crusher to achieve automatic control and remote operation.

[0044] The design of the support plate 1 and the adjustment frame 2 enables the adjustment mechanism to be flexibly adjusted around the impact plate. The coordinated use of the adjustment screw rod 3, the spring screw rod 4 and the hydraulic cylinder 5 can realize the position adjustment of the impact plate to meet the needs of different materials and crushing conditions. The preload force of the spring screw rod 4 can provide a certain stability and anti-swing ability to protect the stability of the impact plate when it is subjected to crushing force.

[0045] Through the adjustment mechanism, the crusher can adapt to different crushing needs. For materials of different hardness and particle size, the position and angle of the impact plate can be adjusted to improve the crushing efficiency. The preload force of the spring screw rod 4 can provide certain protection to prevent the impact plate from swinging backward when impacted, thereby improving the service life and reliability of the equipment. The adjustment function of the hydraulic cylinder 5 can control the distance between the impact plate and the rotor plate hammer, thereby achieving the fineness adjustment of material crushing. The entire adjustment mechanism is easy to operate and can achieve fast and accurate adjustment, thereby improving the use efficiency and production capacity of the crusher.

[0046] In summary, the crushing liner adjustment mechanism of the impact crusher can provide good crushing effect and equipment performance through reasonable structural design and technical coordination.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
