[0002] After a period of use, the hammer and screen roller of the crushing device will be worn to a certain extent. At this time, the gap between the hammer and the screen roller will become larger. The last screen roller of the crusher and the hammer are mainly crushed by extrusion, which makes the gap between the hammer and the screen roller particularly important and directly controls the particle size of the material. Usually, the last screen roller is set as a movable adjustable screen roller. By changing the position of the adjustable screen roller to control the gap between the hammer and the screen roller, the wear of the hammer and the screen roller can be compensated.

[0031] At least one pair of the first supporting ribs 11 are respectively disposed at two ends of the bottom of the adjusting portion to support the adjusting portion; and the supporting plate 13 is disposed at one side of the adjusting portion.

[0037] Example 2

[0038] Second, see Figures 1 to 3 The embodiment of the utility model provides a screen roller adjustment mechanism as described in any of the above items, characterized in that the two ends of the bearing seat are symmetrically arranged, and are both provided with the supporting part and the adjusting part; the adjusting parts at both ends of the bearing seat simultaneously adjust the position of the wedge block; the adjustment position of the wedge block is determined according to the scale mark; the gap between the hammer head of the crushing device and the screen roller 2 is also determined according to the scale mark, and directly controls the size of the discharge particle size of the material.

[0039] Example 3

[0040] See also Figures 1 to 3 The embodiment of the utility model provides a screen roller adjustment mechanism for a crushing device. The screen roller adjustment mechanism for a crusher is composed of a screen roller 2, a bearing seat 3, a sealing ring, a fastening bolt, an end cover, a wedge block 21, a slideway 22, a plurality of support ribs, an adjustment bolt and a support plate 13. For details, please refer to Figure 1 and Figure 2 ; The screen roller 2 is mounted on the bearing seat 3 through a bearing, and a seal is provided inside the bearing seat 3; The bearing seat 3 is mounted on the crusher shell 1 through a bolt connection, and the bolt holes on the bearing seat 3 are strip holes. The function of the strip holes is to provide more screening surfaces on the screen roller 2 to improve the screening efficiency. These strip holes can increase the path for the material to pass through, thereby increasing the chance of screening and helping to prevent blockage. They allow the material to pass through the screen more easily while maintaining an effective screening area, thereby improving screening efficiency and screening capacity. The screw of the fastening bolt that fixes the bearing seat 3 faces the outside of the crusher, and the head of the bolt is welded to the inside of the crusher shell 1. The bearing seat 3 is fixed by a nut on the outside of the crusher shell 1. The lower part of the bearing seat is an inclined surface. The wedge block 21 is installed under the bearing seat. The inclined surface of the wedge block 21 is installed in contact with the inclined surface of the bearing seat 3. The wedge block 21 is installed in the slideway below. The wedge block 21 can move back and forth in the slideway 22. The slideway 22 is also marked with a scale of "the distance between the screen roller and the hammer head (before wear)". For details, please refer to Figure 3The slideway 22 is welded to the outside of the casing and supported by the first support rib 11. There are two adjustment bolts on one side of the wedge block 21, and the adjustment bolts are inserted into the adjustment bolt holes on the support plate 13. A second support rib 12 is installed on one side of the support plate 13 to reinforce the support plate 13. After the crusher has been used for a period of time, the gap between the hammer head and the screen roller 2 becomes larger. When it is necessary to adjust the distance between the screen roller 2 and the hammer head, loosen the four sets of adjusting bolts that fix the bearing seat 3, but do not need to remove them, and then rotate the adjusting bolts to move the adjusting bolts along the inner side of the support plate. The adjusting bolts push the wedge block 21 to move in the direction of the support plate 13 as described in the principle, and the inclined surfaces of the wedge block 21 and the bearing seat 3 will push the bearing seat 3 upward, and the bearing seat 3 will drive the components on the bearing seat 3 and the screen roller 2 to move upward together, thereby reducing the gap between the screen roller 2 and the hammer head. When the screen roller is adjusted to the right position, tighten the fastening bolts of the bearing seat 3 to fix the bearing seat 3 to prevent the bearing seat 3 from moving downward, and at the same time, install the nut 23 on the adjusting bolt close to the support plate to prevent the adjusting bolt from moving backward during use. By observing the position of the lower end of the wedge block 21 corresponding to the scale on the slideway 22, the specific gap between the hammer head and the screen roller 2 can be known.

[0041] If you want to increase the distance between the hammer head and the screen roller, the adjustment process is opposite to the above steps.

[0042] The screen roller adjustment mechanism can move the screen roller 2 to adjust the distance between the hammer head and the screen roller 2. Through multiple fixations, the position of the screen roller 2 will not change during use. At the same time, the position of the scale of the head of the wedge block 21 on the slideway 22 can be observed, and the specific gap between the screen roller 2 and the hammer head can be clearly known.

[0043] Example 4

[0044] Third, see Figures 1 to 3 The embodiment of the utility model provides a crushing device, including a screen roller adjustment mechanism as described in any of the above embodiments; by directly adjusting the screw 24 and pushing the wedge 21, the position of the screen roller of the bearing seat is adjusted to ensure the processing accuracy. This adjustment is simple, and the position of the screen roller will not change during use. At the same time, the position of the scale of the wedge 21 on the slide 22 can be observed, and the specific gap between the screen roller and the hammer head can be clearly known.

[0045] Example 5
