Description

Technical Field

[0001] The utility model relates to the technical field of rotor crushers, in particular to a screen plate assembly for a rotor crusher. Background Art

[0002] The rotor crusher, also known as a hammer crusher, is primarily suitable for crushing materials such as calcite, limestone, brick and tile factory cinders, furnace slag, slag, shale, coal gangue, and construction waste. It solves the problem of using gangue and cinders as additives and internal fuel in brick factories, and crushing high-moisture materials used in standard bricks and hollow bricks produced using gangue and shale. This machine is equivalent to two hammer crushers combined into one, forming a rational whole with two sets of rotors connected in series.

[0003] At present, when using a traditional rotor crusher, the staff first starts the motor, and the motor drives the internal main shaft to rotate through the pulley and belt. When the main shaft rotates, it will drive multiple groups of hammers to rotate. When the hammers rotate, the staff can put the material to be crushed from the feed port. After putting it in, the material contacts the hammers and is crushed by the impact plate.

[0004] Since the rotor crusher will easily find that the crushed materials are of different sizes after crushing the materials, the staff needs to transport the crushed materials to the screening machine, and then use the screening machine to screen and classify the materials of different sizes. After classification, the staff will transport the unqualified materials to the rotor crusher again for secondary crushing. After crushing, the materials will be screened again until they are crushed into qualified materials. This crushing method is not only inefficient, but also increases the labor of the staff and the overall crushing cost. Utility Model Content

[0026] In order to solve the technical problems in the background technology, the following screen plate assembly for a rotor crusher is provided:

[0032] like Figures 1-6 As shown, based on the above embodiment, this embodiment further provides the following content:

[0033] The second screening mechanism 8 includes a screen frame 81, the screen frame 81 is installed at the lower part of the shell 1, and a T-shaped slot 82 is provided on the upper part of the inner cavity of the screen frame 81, and a screen plate component 83 is slidably connected in the T-shaped slot 82. An inclined plate 84 is fixedly connected to the inner cavity of the screen frame 81 and located below the screen plate component 83. A reciprocating component 85 is installed on one side of the outer surface of the screen frame 81, and one end of the reciprocating component 85 is connected to the screen plate component 83; the screen plate component 83 includes a U-shaped filter plate 831, and T-shaped blocks 832 are fixedly connected on both sides of the U-shaped filter plate 831. The U-shaped filter plate 831 slides in the T-shaped slot 82 through the T-shaped block 832, and one end of the U-shaped filter plate 831 is fixedly connected to the reciprocating block 833. The top surface is provided with a socket 834; the reciprocating component 85 includes a reciprocating motor 851 and a T-shaped slide bar 852. One side of the screen frame 81 is fixedly connected to the reciprocating motor 851, and the internal sliding connection of the screen frame 81 is the T-shaped slide bar 852. One side of the T-shaped slide bar 852 is provided with a vertical groove 853. One end of the T-shaped slide bar 852 is fixedly connected to a rectangular sleeve 854, and the top surface of the rectangular sleeve 854 is fixedly connected to a latch damping rod 855. The top surface of the latch damping rod 855 is fixedly connected to an insertion rod 856. The output shaft end of the reciprocating motor 851 is fixedly connected to a disc 857, and one side of the disc 857 is fixedly connected to a cylinder 858. The outer surface of the cylinder 858 slides in the vertical groove 853.

[0034] The reciprocating component 85 drives the U-shaped filter plate 831 and the T-shaped block 832 to slide in the T-shaped slot 82. When the U-shaped filter plate 831 moves back and forth, the crushed material can be screened and classified.

[0035] By pulling the insertion rod 856, the latch damping rod 855 is stretched. When the insertion rod 856 is pulled, the insertion rod 856 will be disengaged from the insertion hole 834. At this time, the staff can replace the U-shaped filter plate 831.

[0036] The working principle and use process of this utility model:

[0037] In use:

[0038] When in use, first put the material into the feed hopper 6. When putting it in, first, start the drive motor 3. When the drive motor 3 is working, it will drive the main shaft 41 to rotate through the pulley and belt. When the main shaft 41 rotates, it will drive the hammer plate 42 to rotate, thereby driving multiple groups of hammer shafts 43 to rotate around the main shaft 41. As the hammer shaft 43 rotates, it will drive the hammer head 44 to rotate. At this time, the falling material will be crushed under the action of the hammer head 44 and the impact plate 7, and the crushed material will fall into the screening drum 21. If it is qualified, it will fall from the discharge hole 23, and the unqualified will remain in the screening drum 21, avoiding the residue and fall of the material. When the material hole 23 is blocked, the main shaft 41 rotates, which will also drive the convex block 45 to rotate. When the convex block 45 rotates, it will indirectly contact the convex circle 27. When contacting with the convex circle 27, it will squeeze the convex circle 27. The convex circle 27 will drive the reciprocating rod 26 to squeeze the reciprocating damping rod 22. At the same time, the reciprocating rod 26 will drive the screening drum 21 to move downward. When it is disengaged, the reciprocating rod 26 will drive the screening drum 21 to reset under the action of the reciprocating damping rod 22, so that the screening drum 21 forms an up and down reciprocating motion, which can make the material in the screening drum 21 shake up and down, and make the material be crushed by the hammer head 44 again. At the same time, the up and down shaking will also clean the feeding hole 23.

[0039] The qualified materials will fall onto the U-shaped filter plate 831. After falling, the reciprocating motor 851 will drive the disc 857 to rotate, thereby driving the cylinder 858 to reciprocate. When the cylinder 858 rotates, it will slide in the vertical slot 853 and drive the T-slide bar 852 to reciprocate. When the T-slide bar 852 reciprocates, it will also drive the U-shaped filter plate 831 to reciprocate, thereby achieving screening and classification of qualified materials.

[0040] When the U-shaped filter plate 831 needs to be replaced later, first, pull the T-shaped slide bar 852. As the T-shaped slide bar 852 moves, the latch damping rod 855 will be stretched. When the plug rod 856 is disengaged from the socket 834, the U-shaped filter plate 831 is pulled to one side, so that the reciprocating block 833 is disengaged from the rectangular sleeve 854, which is convenient for the staff to replace the U-shaped filter plate 831 later.

[0041] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations.
