DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: Refer to Figures 1-5 A height adjustment mechanism for the grate bars of a fine crusher shown, which includes a grate bar seat 2 slidably connected in a fine crusher base 1. The grate bar seat 2 is limited by a support mechanism provided on the fine crusher base 1, and a tilting mechanism is provided in a hinge hole 11 provided on the outer wall of the fine crusher base 1. The tilting mechanism is used to change the distance between the grate bar seat 2 and the crushing roller, and the support mechanism realizes the limitation and support of the grate bar seat 2.

[0021] Tilting mechanism: A hinge member 3 is hinged in the hinge hole 11. The hinge member 3 is a transparent cylindrical structure, and a crowbar 4 is slidably connected in the hinge member 3. And a support member cooperating with the crowbar 4 is provided at the bottom of the grate bar seat 2. When the crowbar 4 tilts and abuts against the support member, the grate bar seat 2 slides in the fine crusher base 1, and in this process, in cooperation with the support mechanism, the height of the grate bar seat 2 is limited, so that materials of different hardnesses and humidities can be processed.

[0022] Support mechanism: A cushion block bin 7 is provided on the outer wall of the fine crusher base 1, and a perforation adapted to the bin chamber 71 is provided on the fine crusher base 1 so that the cushion blocks can be inserted between the base 6 and the bottom block 5 through the perforation. During the process of the tilting mechanism lifting the grate bar seat 2, in order to prevent the cushion blocks 8 in the bin chamber 71 from accidentally entering the insertion holes 51 of the bottom block 5, therefore, during this process, tools such as bandages are first used to connect the lever rods 81 on the outer walls of the cushion blocks 8 so that the four cushion blocks 8 are integrated. When the lifting task is completed, the bandage is loosened. Under the action of the spring 9, the bottom cushion block 8 is inserted between the base 6 and the bottom block 5 to act as a "cushion block", and the high cushion block 8 is inserted into the insertion hole 51 to complete the limitation of the grate bar seat 2.

[0023] Grate bar seat 2: Pressure plates 22 and limit strips 23 are provided on the opposite surfaces of two groups of mounting plates 21. In the space between the pressure plates 22 and the limit strips 23, grate bars are placed. In order to limit the grate bars, positioning holes 24 are provided at the ends of the mounting plates 21. Positioning members 25 are threadedly connected in the positioning holes 24, and positioning blocks are sleeved on the positioning members 25 in order to press the grate bars.

[0024] The working principle of this utility model: During processing, according to the condition of the material, after completing the processing of the material inside this time, the machine is temporarily stopped. Subsequently, the crowbar 4 is inserted into the hinge 3, and the end of the crowbar 4 is made to abut against the top of the support. Then, the grate bar seat 2 is lifted, causing it to slide upward within the fine crusher seat 1, reducing the spacing between the grate bars and the crushing rollers. Subsequently, during the movement, the spacer blocks 8 within the chamber 71 of the spacer block bin 7 always have an outward force under the action of the spring 9. After the bottom block 5 is separated from the base 6, the jack 51 on the bottom block 5 is sequentially connected to the spacer blocks 8. In order to avoid interference caused by the spacer blocks 8 being inserted into the jack 51 during the adjustment process, therefore, before completing the adjustment, multiple sets of lever rods 81 are first connected to each other. When the grate bar seat 2 is lifted to an appropriate height, the limit on the lever rods 81 is released. The bottom lever rod 81 is placed between the bottom block 5 and the base 6, and one set of spacer blocks 8 is inserted into the jack 51 and cooperates with the other spacer blocks 8 to complete the limitation of the grate bar seat 2. Subsequently, the crowbar 4 is removed.

[0025] To facilitate the installation and removal of the grate bars, on the mounting plate 21, a pressing plate 22 and a limiting strip 23 are designed in sequence from the center of the circle outwards. The space between the pressing plate 22 and the limiting strip 23 is used to place the grate bars. A positioning hole 24 is provided at the end of the mounting plate 21, and a positioning member 25 is threadedly connected within the positioning hole 24. The positioning member 25 is a bolt. Since different grate bars require different processing, the spacing between the grate bars is also different, such as five millimeters, one centimeter, etc. Therefore, different positioning blocks are sleeved on the positioning member 25 to achieve the pressing of the grate bars.
