Description

Technical Field

[0001] This utility model belongs to the technical field of jaw crusher components, specifically a jaw crusher inclined wedge adjustment rotating seat. Background Technology

[0002] Jaw crushers, also known as jaw breakers or tiger's mouth crushers, consist of two jaw plates—a moving jaw and a stationary jaw—forming a crushing chamber. They mimic the jaw movements of an animal to crush materials. They are widely used in mining, metallurgy, building materials, highway, railway, water conservancy, and chemical industries for crushing various ores and large materials. Existing jaw crushers have an oil injection hole on the wedge-adjusting rotating seat, sealed with a common sealing plug. However, during use, when the plug is inserted into the oil injection hole, oil residue may adhere to the hole. Forcing the plug in may cause it to rotate briefly at the injection hole, making a seal difficult. Furthermore, dust and impurities remaining near the injection hole can easily fall into it, affecting the oil and causing insufficient lubrication, resulting in uneven rotation of the rotating seat. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a jaw crusher oblique wedge adjustment rotating seat, which has the advantages of anti-rotation and dust prevention.

[0004] The purpose of this utility model can be achieved through the following technical solution: a jaw crusher inclined wedge adjustment rotating seat, including a seat body, a first through hole is provided through the seat body, an oil injection pin is installed on the seat body, the oil injection pin has an oil injection hole, and a third through hole for placing the oil injection pin is opened on the top of the seat body, the third through hole is connected to the first through hole.

[0005] The oil injection pin is engaged with the third through hole at the top of the seat body;

[0006] The base and the third through hole are also provided with a stepped part, and a dustproof ring is installed on the stepped part to prevent dust from falling into the third through hole. The dustproof ring is arranged around the outside of the oil injection pin to prevent dust and seal the third through hole.

[0007] Preferably, the base has four second through holes arranged at the same distance from the first through hole as the center for connection and fixation.

[0008] Preferably, a material placement groove is provided around the stepped portion, and the dustproof ring is installed in the material placement groove of the stepped portion.

[0009] Preferably, the third through hole is located at the exact center of the top of the base.

[0010] Preferably, the first through hole is located at the center of the front surface of the base.

[0011] Compared with the prior art, the advantages of this utility model are: by adding a third through hole and a dustproof ring, and because the base body and the third through hole are also provided with a stepped part, it is beneficial to improve the anti-rotation and seal the third through hole. At the same time, by setting a dustproof ring at the third through hole, some dust particles are blocked by the dustproof ring, which helps to prevent dust from entering the third through hole, thus playing a good role in dust prevention and anti-rotation, and making it more practical.

[0014] Figure 3 This is an enlarged view of point A in this utility model.

[0015] In the figure, 2 is the base; 21 is the first through hole; 3 is the third through hole; 31 is the stepped part; 32 is the material trough; 4 is the oil injection pin; 41 is the oil injection hole; 5 is the dustproof ring; and 6 is the second through hole. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] A jaw crusher inclined wedge adjustment rotating seat includes a seat body 2, a first through hole 21 is provided through the seat body 2, an oil injection pin 4 is installed on the seat body 2, the oil injection pin 4 has an oil injection hole 41, and a third through hole 3 for placing the oil injection pin 4 is opened on the top of the seat body 2, the third through hole 3 is connected to the first through hole 21.

[0018] The oil injection pin 4 is engaged with the third through hole 3 at the top of the seat body 2;

[0019] The base 2 and the third through hole 3 are also provided with a step portion 31. A dustproof ring 5 is installed on the step portion 31 to prevent dust from falling into the third through hole 3. The dustproof ring 5 is arranged around the outside of the oil injection pin 4 to prevent dust and seal the third through hole 3.

[0020] With the above structure, by adding a third through hole 3 and a dustproof ring 5, before lubricating the rotating seat, the oil injection pin 4 is inserted into the third through hole 3. Since the seat body 2 and the third through hole 3 are also provided with a stepped part 31, after the oil injection pin 4 is inserted into the third through hole 3, its top pin end can just abut against the stepped part 31, and the pin shaft surface of the oil injection pin 4 abuts against the inner wall of the third through hole 3. At the same time, a dustproof ring 5 is provided, and the top pin end of the oil injection pin abuts against the dustproof pad on the stepped part 31. Since the surface roughness of the dustproof ring 5 and the pin end is relatively large, it can prevent the oil injection pin 4 from rotating too much, which is beneficial to improving the anti-rotation and sealing of the third through hole 3. At the same time, by providing a dustproof ring 5 at the third through hole 3, some dust particles are blocked by the dustproof ring 5, which is beneficial to prevent dust from entering the third through hole 3, which plays a good role in dust prevention and anti-rotation, and is more practical.

[0021] Specifically, such as Figures 1 to 3 As shown, the base 2 has four second through holes 6 arranged at the same distance from the first through hole 21, with the first through hole 21 as the center, for connection and fixation.

[0022] By adopting the above structure and setting the second through hole 6, it is easier to connect and fix the rotating seat with other adjacent jaw crusher components, resulting in higher mechanical integration and more reliable connection and fixation.

[0023] like Figures 1 to 3 As shown, a material placement groove 32 is provided around the stepped portion 31, and the dustproof ring 5 is installed in the material placement groove 32 of the stepped portion 31. By providing the material placement groove 32, it is convenient to put the dustproof ring 5 into the material placement groove 32, and to prevent the dustproof ring 5 from falling out of the third through hole 3 in some special circumstances. This helps to ensure the normal operation of the device and extend the service life of the device.

[0024] like Figures 1 to 3 As shown, the third through hole 3 is located at the center of the top of the base 2.

[0025] like Figures 1 to 3 As shown, the first through hole 21 is located at the center of the front of the base 2.

[0026] The first through hole 21 and the third through hole 3 are respectively located at the center of the top of the base 2 and the center of the front of the base 2, which facilitates better matching and connection with other components and makes the device highly integrated.
