Accordingly, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In addition, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Referring to fig. 1 to 5, the impact frame adjusting apparatus includes: mount 10, resilient mounting assembly 20, and a plurality of connecting rods 30 passing through crusher housing 40 to connect mount 10 with impact bracket 50. Wherein the resilient mounting assembly 20 comprises: a plurality of adjusting rods 21, a limiting component 22, and a spring 23, a first nut 24, a second nut 25 and a third nut 26 which are arranged corresponding to the adjusting rods 21 one by one; the adjusting rod 21 sequentially penetrates through the crusher shell, the mounting seat 10 and the spring 23 from the inner side to the outer side of the crusher shell; the first nut 24 is mounted on one end of the adjusting rod 21 inside the crusher housing 40; the second nut 25 and the third nut 26 are arranged at one end of the adjusting rod 21, which extends out of the spring 23, and are abutted together, wherein the third nut 26 is positioned at one side far away from the spring 23; the spring 23 is in a compressed state; the position-limiting part 22 is sleeved on the third nut 26, and a position-limiting structure 22a which is matched with the third nut 26 in shape to limit the rotation of the third nut 26 is formed on the position-limiting part.

It should be noted that the impact frame adjusting device is used for connecting the crusher shell and the impact frame, and the impact plate is installed on the impact frame. The spring 23 is in a compressed state and can provide a pre-load force. The pre-tightening force provided by the spring 23 can make the impact plate absorb part of kinetic energy when being impacted by materials, and provide certain buffering to protect other components. When the crusher works, materials impact the impact plate continuously, so that the elastic force generated by the spring 23 is changed continuously, and the connecting parts at the two ends of the adjusting rod 21 need to bear the extrusion force changed continuously, so that the threaded connection at one end of the adjusting rod 21 extending out of the spring is easy to loosen.

In the embodiment of the application, a second nut 25 and a third nut 26 are mounted at one end of the adjusting rod 21, which extends out of the spring 23, and are abutted together; two nuts arranged in succession can effectively improve the reliability and stability of connection. The limiting component 22 limits the rotation of the third nut 26 positioned at the outer side through the limiting structure 22a, and further improves the reliability and stability of the connection of the end of the adjusting rod 21.

Specifically, since the elastic mounting assembly 20 has the plurality of adjustment rods 21 and the plurality of third nuts 26 corresponding to the adjustment rods 21 one by one, the stopper member 22 is also provided with the plurality of stopper structures 22a corresponding to the third nuts 26 one by one. The rotation of the third nut 26 is limited, and the second nut 25 is limited to an inner position by the third nut 26.

Referring to fig. 4 and 5, the position restricting member 22 is a plate; the position-limiting structure 22a is a hexagonal through hole adapted to the cross-sectional shape of the third nut 26. The third nut 26 is fitted in the hexagonal through hole and is prevented from rotating due to the shape restriction.

Referring to fig. 4, the resilient mounting assembly 20 further includes a spring hold down 27; the spring holding plate 27 is embedded between the spring 23 and the second nut 25. The spring hold down 27 is used to compress the spring 23 against the spring 23.

Further, the spring pressing plate 27 and the limiting component 22 are connected together through bolts, and a limiting sleeve 28 through which the bolts can pass is arranged between the two. Here, the connection of the spring pressing plate 27 and the position restricting member 22 by the bolt may be used to fix the position of the position restricting member 22. Wherein, the limiting sleeve 28 is used for limiting.

Referring to fig. 6, the connecting rod 30 is mounted with nuts on both sides of the mount 10; a spherical washer 31 and a conical washer 32 are arranged between the nuts on the two sides and the mounting seat 10; wherein, the conical washer 32 is arranged in the annular groove 11 on the side surface of the mounting seat 10; the spherical surface of the spherical washer 31 and the tapered surface of the tapered washer 32 are in contact with each other. Annular groove 11 may be used to define the location of beveled washer 32; when the nuts on both sides are tightened, the spherical surface of the spherical washer 31 and the conical surface of the conical washer 32 are in contact with each other, so that the tie rod 30 and the corresponding mounting hole of the mount base 10 are held in substantially fixed relative positions. The relative position here may be such that the connecting rod 30 is coaxial with the inner surface of the mounting hole. Therefore, the contact and extrusion between the outer surface of the connecting rod 30 and the inner surface of the mounting hole can be avoided, and the stress condition between the connecting rod 30 and the mounting seat 10 is improved.

Since the annular groove 11 is used for mounting the bevel washer 32, the diameter of the annular groove 11 may be set to be equal to the outer diameter of the bevel washer 32 or slightly larger than the outer diameter of the bevel washer 32.

Referring to fig. 5 and 6, the connecting rod 30 is fitted with a fourth nut 33 and a fifth nut 34 on the side of the mounting block 10 remote from the crusher housing 40, and the two abut together; wherein, the fifth nut 34 is located at a side far away from the mounting seat 10; the mounting base 10 is fixed with a blocking component 12, which is provided with a blocking structure 12a that can block the fifth nut 34. The detent structure 12a can be used to limit rotation of the fifth nut 34, increasing the stability of the threaded connection thereat.

In some embodiments, the detent structure 12a is a hexagonal through hole that is adapted to the cross-sectional shape of the fifth nut 34.

Referring to fig. 7, in some embodiments, the connecting rods 30 are distributed on both sides of the resilient mounting assembly 20. The connecting rod 30 is directly connected to the impact beam 50, and is a directly stressed component, so that it is distributed on both sides of the elastic mounting assembly 20 to be beneficial to optimize the stress condition of the mounting seat 10.

Further, the end of the connecting rod 30 extending into the crusher housing 40 is provided with a hinged seat 35 for connection to the counterattack frame.

In addition, the embodiment of the application also shows a crusher, and the crusher adopts the impact frame adjusting device described in the embodiment part. For a detailed description, reference may be made to the description of the adjustment device for the impact frame in the above embodiments, and details are not repeated here.
