[0028] Referring to the drawings Figures 1-4 The utility model discloses an ore crusher with adjustable filter hole size, comprising:

[0029] The base 1 is provided with a vibrating motor on the side plate.

[0030] The crushing box 3 is located above the base 1, and one supporting frame 4 is arranged on each side of the crushing box 3;The supporting frame 4 is fixed on the base 1 at the bottom of the supporting frame 4 on both sides, which can support the crushing box 3 stably;The top of the crushing box 3 is provided with a feeding port 5, and the bottom is provided with a discharging port 6.

[0031] The first adjusting assembly 7 is located below the crushing box 3, comprising symmetrically arranged supporting plate one 8 and supporting plate two 9 and adjusting frame 10 located between the two supporting plates;The two ends of the adjusting frame 10 are fixed on the supporting plate one 8 and the supporting plate two 9 through bolts respectively, and the inside is provided with two symmetric guide rods 11;A plurality of compression springs one 12 are arranged on the guide rod 11;A plurality of adjusting plates 13 are arranged in the adjusting frame 10, and the two ends of the adjusting plate 13 are slidably connected with the guide rods 11 on both sides respectively;The compression spring one 12 is located between the adjacent two adjusting plates 13;The vertical plate of the supporting plate one 8 is provided with an avoiding slot 14, and the avoiding slot 14 is provided with a limiting plate 15;The limiting plate 15 is penetrated by the two guide rods 11, and the two ends are fixed on the supporting plate one 8 through bolts;A push plate 16 is further arranged between the limiting plate 15 and the adjusting plate 13;The two ends of the push plate 16 are penetrated by the two guide rods 11, and the middle part is rotatably connected with a threaded rod 17;The threaded rod 17 penetrates the limiting plate 15 and is threadedly connected with the limiting plate 15;The end of the threaded rod 17 away from the push plate 16 is provided with a ring handle 18;

[0032] The second adjusting assembly 19 is arranged below the first adjusting assembly 7 and is arranged vertically with the first adjusting assembly 7; the second adjusting assembly 19 is the same structure as the first adjusting assembly 7, and when the interval adjustment of the internal adjusting plate 13 is performed, the second adjusting assembly 19 is adjusted synchronously with the first adjusting assembly 7.

[0033] In the embodiment, a vibration motor is arranged on the side plate of the base 1, which is shown in the drawings, for continuously vibrating the first adjusting assembly 7 and the second adjusting assembly 19, so as to facilitate the falling of the crushed materials from the material leakage hole 2. A screening area is arranged between the top plate of the support plate one 8 and the top plate of the support plate two 9; the screening area is located directly above the material leakage hole 2 and corresponds to the position of the material outlet 6. After the ore is crushed in the crushing box 3, the ore is divided by the flow dividing plate 21 and then falls through the material outlet 6 to the screening area. The smaller crushed materials will fall from the intervals of the adjusting plate 13 in the process of continuous vibration. When the crushing is blocked or there are too many crushed materials that cannot fall, the handle 18 can be rotated to increase the interval of the adjusting plate 13, so as to screen the larger crushed materials.

[0034] The rotation of the handle 18 drives the threaded rod 17 to rotate and drives the push plate 16 to slide along the guide rod 11, so as to press the adjusting plate 13. When the adjusting plate 13 is pressed by the push plate 16, the compression spring one 12 between the adjusting plate 13 is compressed, so as to change the interval between the adjusting plate 13, which is convenient for screening the crushed materials of different sizes. When the crushed materials are stuck in the square filter hole formed by the cooperation of the adjusting plate 13 of the first adjusting assembly 7 and the adjusting plate 13 of the second adjusting assembly 19, the crushing is easily blocked, which affects the screening efficiency. At this time, the staff can rotate the handle 18 to expand the interval between the adjusting plate 13, so that the stuck crushed materials can fall smoothly, avoiding long-term blocking.

[0035] When the screening area on the adjusting plate 13 accumulates too many large crushed materials, the crushing operation of the crushing roller 20 can be temporarily stopped, the handle 18 is rotated to completely expand the compression spring one 12, so that the accumulated large crushed materials are completely dropped out, and then the interval between the adjusting plate 13 is adjusted again for subsequent screening operation. When the compression spring one 12 is completely expanded, the interval between the adjusting plate 13 is slightly larger than the minimum interval between the two crushing rollers 20, so that the large crushed materials can fall smoothly.

[0036] Two crushing rollers 20 are arranged in the crushing box 3, and a flow dividing plate 21 is arranged below the cooperation area of the two crushing rollers 20. The flow dividing plate 21 is arranged on the load bearing rod 22, and the two ends of the load bearing rod 22 are fixedly welded to the inner wall of the crushing box 3. The flow dividing plate 21 can divide the crushed materials of the ore, so that the materials fall on both sides of the screening area, avoiding the materials from piling up in the middle of the screening area, which is beneficial to speed up the screening efficiency.

[0037] In addition, the load-bearing rod 22 is provided with a containing groove 23 at the top; the bottom of the flow distribution plate 21 is located in the containing groove 23 and is provided with a containing groove 24; a plurality of compression springs 25 are arranged in the containing groove 24; the bottom of the compression spring 25 abuts against the bottom of the containing groove 23, and the top of the compression spring 25 abuts against the top of the containing groove 24, so as to play a damping effect, avoid damage of the flow distribution plate 21 under continuous impact of the crushed materials, and be beneficial to prolong the service life.

[0038] It should be noted that the top of the flow distribution plate 21 is triangular, so as to facilitate distribution of the crushed materials; the two sides of the flow distribution plate 21 are provided with baffle plates 26, and the inner sides of the baffle plates 26 are attached to the outer wall of the load-bearing rod 22. When the top of the flow distribution plate 21 is impacted by the crushed materials, the compression springs 25 are compressed, at this time, the baffle plates 26 can slide downward along the outer wall of the load-bearing plate to buffer, and can also play a limiting effect, so as to avoid random shaking of the top of the flow distribution plate 21.

[0039] The ore crusher with adjustable filter hole size can adjust the interval between the adjusting plates 13 in the first adjusting assembly 7 and the second adjusting assembly 19 through the annular handle 18, so as to facilitate screening of ore crushed materials with different sizes; meanwhile, when blockage occurs, the interval of the adjusting plates 13 can be increased to make the blocked crushed materials fall down smoothly, so that the blockage can be quickly dredged, the long-term blockage can be avoided to affect the subsequent screening efficiency of the crushed materials, the ore crusher is very practical, and has good market application prospect.

[0040] The foregoing description of specific exemplary embodiments of the present application is intended to be illustrative only and is not intended to limit the present application to the precise forms described. Many modifications and variations are possible in light of the above teachings without departing from the spirit or essential characteristics of the present application. The exemplary embodiments were chosen and described in order to explain the principles of the present application and its practical application and to allow others skilled in the art to understand the present application for various exemplary embodiments with various modifications as are suited to the particular use contemplated. The scope of the present application is intended to be defined by the claims and their equivalents.
