Description

Technical Field

[0001] This utility model relates to the field of crusher components, specifically a three-cheek plate for preventing material leakage in a crusher. Background Technology

[0002] During operation, material leaks from the gap between the pressure rollers and the three cheek plates on both sides of the existing crusher, causing uncrushed material to mix with the crushed material, resulting in a decrease in the quality of the finished product. During long-term operation, material may accumulate and get stuck between the pressure rollers and the inner wall of the crusher frame during the leakage process. The pressure rollers will experience abnormally high temperatures due to friction with the stuck material. This heat will be conducted to the bearings mounted on the pressure rollers, reducing their lubrication capacity, increasing the internal friction coefficient of the bearings, and shortening their service life.

[0038] This utility model proposes a three-cheek plate for preventing material leakage in crushers, which can be used in the design and process of crusher components. This utility model does not limit the type of crusher, but the structure of the three-cheek plate body 1, upper sealing plate 2 and lower sealing plate 3 is particularly suitable for preventing material leakage in crushers.

[0039] In general, the three-cheek plate for preventing material leakage in a crusher proposed in this utility model mainly includes: a three-cheek plate body 1, an upper sealing plate 2, and a lower sealing plate 3. (See also...) Figure 1 It shows the arrangement of the three-cheek plate body 1, the upper sealing plate 2, and the lower sealing plate 3.

[0040] In this preferred embodiment, a first elongated hole 11 is provided in the center of the three-cheek plate body 1, and a second elongated hole 21 is provided in the center of the top of the upper sealing plate 2. The first elongated hole 11 and the second elongated hole 21 are coaxially arranged.

[0041] In the above structure, the oblong hole can be used to finely adjust the relative position of the sealing plates 2 on the three cheek plate main body 1 during installation according to the tolerance of the frame.

[0042] In this preferred embodiment, the three-cheek plate body 1 and the upper sealing plate 2 are fixedly attached by bolt No. 4. One side of bolt No. 4 abuts against the three-cheek plate body 1, and the other side passes through the first elongated hole 11 and the second elongated hole 21 in sequence, and is connected to the inner wall of the crusher frame 6 by threaded engagement. The upper sealing plate 2 is located between the left and right end faces of the pressure roller 7 and the inner wall of the crusher frame 6. One side of the upper sealing plate 2 is in close contact with the inner wall of the crusher frame 6, and the other side of the upper sealing plate 2 does not contact the left or right end face of the pressure roller 7.

[0043] In the above structure, the upper sealing plate 2 mainly fills the gap between the pressure roller 7 and the inner wall of the crusher frame 6. At the same time, in order to prevent affecting the operating efficiency of the pressure roller, the upper sealing plate 2 will be in close contact with the inner wall of the frame, but will not contact the pressure roller 7.

[0044] In this preferred embodiment, the bottom of the upper sealing plate 2 is provided with a positioning groove 22 on the side near the crusher frame 6, and the top of the lower sealing plate 3 is provided with an installation strip 31 on the side away from the inner wall of the crusher frame 6. The top of the lower sealing plate 3 and the bottom of the upper sealing plate 2 are connected by the positioning groove 22 and the installation strip 31. The bottom of the lower sealing plate 3 is provided with three elongated holes 32 on the left and right sides. Two bolts 33 are inserted into the three elongated holes 32. One side of the two bolts 33 abuts against the outer side of the lower sealing plate 3, and the other side of the two bolts 33 passes through the three elongated holes 32 and is connected to the inner wall of the crusher frame 6.

[0045] In the above structure, the positioning groove 22 and the mounting strip 31 work together to reduce the amount of fasteners used on the lower sealing plate 3, making it easier to disassemble and, at the same time, making it easier to position the lower sealing plate 3 during installation.

[0046] In this preferred embodiment, the bottom left and right sides of the three-cheek plate body 1 are provided with a material-blocking arc groove 12. The material-blocking arc groove 12 is sleeved on the outside of the chamfer on the left and right sides of the pressure roller 7. The material-blocking arc groove 12 is coaxial with the center of the pressure roller 7. The diameter of the material-blocking arc groove 12 is greater than the minimum diameter of the chamfer on the left and right sides of the pressure roller 7 and less than the maximum outer diameter of the pressure roller 7.

[0047] The above-mentioned three-cheek plate main body 1 structure can be compared Figure 5 , 6 In the prior art, the existing three-cheek plate body 1 is designed to prevent material from leaking into the crusher's casing. In order to prevent friction between the material-blocking arc groove 12 and the pressure roller 7 and to facilitate installation, the diameter of the material-blocking arc groove 12 is larger than the diameter of the pressure roller 7. Furthermore, the center of the friction material-blocking arc groove 12 and the center of the pressure roller 7 are not on the same axis.

[0048] In this embodiment, preferably, the maximum distance between the lower sealing plates 3 located on the left and right sides of the pressure roller 7 is less than the width of the discharge chute 61 at the bottom of the crusher frame 6.

[0049] The above structure is designed to prevent material from accumulating on the discharge chute 61 platform of the frame.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
