[0002] Crusher can be divided into medical crusher and mining crusher according to the major categories. Mining crusher is suitable for crushing massive hard rocks in mines. Its typical granite output particle size is ≤40mm, accounting for 90%. The machine can process materials with a side length of 100-500 mm. Its compressive strength can reach up to 350 MPa. It has the advantages of large crushing ratio and cubic particles after crushing. Mining crushing machinery refers to a crushing machinery in which the content of particles larger than three millimeters in the discharge accounts for more than 50% of the total discharge volume. In the process of crushing the ore by the crusher, the ore needs to be put into the crusher through the feed port.

[0007] Through the above technical solution, the disc body is first sleeved on the main shaft and the buffer cylinder is sleeved on the buffer shell. At this time, the limit piece is inserted into the slide groove, and as the buffer cylinder continues to move downward, the limit piece is retracted into the buffer cylinder. Then the buffer cylinder is rotated and the limit piece is coincident with the limit groove. Then the buffer cylinder is released. At this time, the movable cylinder is reset and the limit piece is inserted into the limit groove, so that the buffer cylinder is limited by the limit groove and the buffer cylinder is connected to the buffer shell.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] Please refer to the attached figure in the instruction manual Figure 1 、 Figure 2 and Figure 3 , the present application provides an embodiment: a crusher distribution plate, including a transmission shaft 1, a buffer shell 2, a main shaft 3 and a plate body 4. The transmission shaft 1 is installed in the crusher, and the plate body 4 facilitates the powder processing of the material falling into the crusher, and then the material is crushed by the crushing mechanism.

[0029] The buffer shell 2 is fixedly set at the upper end of the transmission shaft 1, the main shaft 3 is vertically inserted into the top surface of the buffer shell 2, the disk body 4 is movably sleeved on the main shaft 3 and connected by setting a connecting piece 5, the lower end of the main shaft 3 is inserted into the buffer shell 2 and fixedly provided with a rubber pad 31, and the rubber pad 31 is connected to the inner bottom wall of the buffer shell 2 by setting a first spring 32. When the material falls on the disk body 4, the disk body 4 is impacted and moves downward. At this time, the disk body 4 drives the main shaft 3 and the rubber pad 31 to move downward, and the first spring 32 is used to buffer the impact force on the disk body 4, thereby reducing the possibility of damage to the disk body 4.

[0030] The connecting piece 5 is threadedly inserted into the top surface of the disk body 4. The connecting piece 5 passes through the disk body 4 and is threadedly inserted into the top end of the main shaft 3. The connecting piece 5 facilitates the connection between the disk body 4 and the main shaft 3, thereby causing the main shaft 3 to move synchronously when the disk body 4 moves, and the rubber pad 31 cooperates with the first spring 32 to cushion the disk body 4.

[0031] A cross groove 51 is provided on the top surface of the connecting piece 5, and a sealing plate 52 is movably provided in the cross groove 51. The sealing plate 52 is connected to the inner bottom wall of the cross groove 51 by providing a second spring 53. The cross groove 51 makes it easy for the operator to use a Phillips screwdriver to disassemble the connecting piece 5, and the second spring 53 pushes the sealing plate 52 upward to facilitate sealing the cross groove 51, thereby reducing the possibility of small materials getting stuck in the cross groove 51, making it difficult for the operator to disassemble the connecting piece 5.

[0032] A buffer cylinder 6 is fixedly provided on the bottom surface of the disc body 4, and the buffer cylinder 6 is movably provided on the buffer shell 2. A plurality of third springs 61 are fixedly provided on the inner top wall of the buffer cylinder 6. The lower end of the third spring 61 abuts against the top surface of the buffer shell 2. When the disc body 4 is impacted, the disc body 4 drives the buffer cylinder 6 to move downward. At this time, the buffer cylinder 6 and the disc body 4 are buffered by the third spring 61, thereby reducing the possibility of damage to the disc body 4.

[0033] Several limit members 7 are provided on the inner side of the buffer cylinder 6, and several limit grooves 8 and slide grooves 9 are opened on the outer wall of the buffer shell 2 along the circumference. The limit members 7 slide with the inner wall of the limit groove 8, and the number of limit members 7 corresponds to the number of limit grooves 8 and slide grooves 9. A groove 62 is opened in the buffer cylinder 6, and the limit member 7 includes a limit rod 71, which is movably inserted in the groove 62. One end of the limit rod 71 is inserted into the groove 62 and connected to the inner wall of the groove 62 by setting a fourth spring 72. The other end of the limit rod 71 slides with the inner wall of the limit groove 8 or the slide groove 9, and the end of the limit rod 71 away from the groove 62 is cut. When the limit rod 71 coincides with the slide groove 9, it is convenient for the operator to disassemble the buffer cylinder 6. When the limit rod 71 coincides with the limit groove 8, it is convenient to install the buffer cylinder 6 on the buffer shell 2, thereby realizing the assembly of the disk body 4.

[0034] The inner bottom wall of the limiting groove 8 or the sliding groove 9 is a beveled surface. When the operator presses the disc body 4 and the buffer cylinder 6 to move downward, the beveled surface of the limiting rod 71 abuts against the beveled surface of the inner bottom wall of the sliding groove 9, thereby prompting the limiting rod 71 to be received in the groove 62. At this time, when the operator rotates the disc body 4 and the buffer cylinder 6, the limiting rod 71 coincides with the sliding groove 9, making it easier for the operator to disassemble the disc body 4 and the buffer cylinder 6.

[0035] Working principle: When using the crusher's material distribution plate, first, the plate body 4 is sleeved on the main shaft 3 and the buffer cylinder 6 is sleeved on the buffer shell 2. At this time, the limiting member 7 is inserted into the slide groove 9, and as the buffer cylinder 6 continues to move downward, the limiting member 7 is accommodated in the buffer cylinder 6. Then, the buffer cylinder 6 is rotated and the limiting member 7 is caused to coincide with the limiting groove 8. Then, the buffer cylinder 6 is released. At this time, the movable cylinder is reset and the limiting member 7 is caused to be inserted into the limiting groove 8, thereby limiting the buffer cylinder 6 through the limiting groove 8 and connecting the buffer cylinder 6 to the buffer shell 2.

[0036] Then the disk body 4 is connected to the main shaft 3 through the connecting piece 5. When the disk body 4 needs to be disassembled, the connecting piece 5 is first disassembled, and then the buffer cylinder 6 is pressed to separate the limit piece 7 from the limit groove 8, and then the buffer cylinder 6 is rotated to cause the limit piece 7 to coincide with the slide groove 9, and then the disk body 4 is pulled upward to separate the buffer cylinder 6 from the buffer shell 2, so that the disk body 4 is more convenient to disassemble.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
