In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] See also Figure 1 , Figure 2 and Figure 3 A multi-circulation crushing device for processing quartz sand, comprising a fixing assembly 4, a rotor assembly 3 and a housing 2 with a main shaft 1 installed, the housing 2 comprising an upper cover 21 and a cylinder 22, the upper cover 21 being detachably mounted on the top of the cylinder 22, the main shaft 1 being rotatably mounted on the upper cover 21, the rotor assembly 3 comprising a plurality of hammer heads 31 and a plurality of hammer discs 32, the plurality of hammer discs 32 being evenly distributed along the axial direction of the main shaft 1, the hammer heads 31 being distributed along the circumferential direction of the hammer discs 32, the fixing assembly 4 integrating the hammer heads 31 with the hammer discs 32 and the hammer discs 32 with the main shaft 1 The outer shell 2 is fixedly connected together, so that the overall structure is convenient for assembly and installation, and is also convenient for subsequent replacement and maintenance of the hammer head 31 or the hammer disc 32, which fully reduces the use of fasteners and improves the convenience of assembly, installation, maintenance and replacement of the crushing device. A screening mechanism 5 is arranged under the outer shell 2. The screening mechanism 5 is a prior art, and the screening mechanism 5 is used to screen the crushed quartz sand, screen out the large particles of quartz sand that do not meet the standards and send it into the outer shell 2 again for crushing, so as to repeat the crushing cycle until the crushed quartz sand reaches the preset standard.

[0024] See also Figure 2 , Figure 3 and Figure 4The fixing assembly 4 includes a top limiting seat 41, a bottom limiting seat 42 and an intermediate limiting connection assembly 43. The top limiting seat 41 and the bottom limiting seat 42 limit the plurality of hammer discs 32 from the top and the bottom respectively. The intermediate limiting connection assembly 43 includes mounting grooves 431 evenly distributed along the circumference of the hammer disc 32 and corresponding to the hammer heads 31 one by one. The hammer heads 31 are inserted into the corresponding mounting grooves 431. The hammer disc 32 and the hammer heads 31 are both provided with mounting holes 432. The hammer disc 32 and the top limiting seat 41 are both fixedly installed with limiting locking pieces 433 below. The limiting locking pieces 433 pass through the bottom The mounting holes 432 on adjacent hammer discs 32 are inserted into the mounting holes 432 on the corresponding hammer heads 31, so that the hammer heads 31 and hammer discs 32 are fixedly connected together and the upper and lower adjacent hammer discs 32 are limited, so that several hammer discs 32 are firmly connected together under the limit of the top limit seat 41 and the bottom limit seat 42, so that this structure only needs to fix and install the top limit seat 41 and the bottom limit seat 42, and there is no need to use a large number of fasteners to fix the hammer head 31 and the hammer disc 32 as well as the hammer disc 32 and the main shaft 1 together, which fully improves the convenience of assembly, maintenance and replacement of the crushing device.

[0025] See also Figure 3 , Figure 4 and Figure 5The inner side of the hammer disc 32 is fixedly installed with a limit piece 434, and the main shaft 1 is fixedly installed with an intermediate limit seat 435. The limit pieces 434 are evenly distributed along the circumference of the hammer disc 32. The intermediate limit seat 435 corresponds to the limit pieces 434 one by one, and a moving groove 436 is provided on the intermediate limit seat 435. The limit piece 434 moves up and down in the moving groove 436. When the hammer head 31 needs to be replaced, it is only necessary to disassemble the cylinder 22 and the bottom limit seat 42. After the bottom limit seat 42 is disassembled, the hammer disc 32 loses the bottom limit and can move downward. The mounting hole 432 on the hammer head 31 is separated from the corresponding limiting locking piece 433, so that the hammer head 31 can be replaced. At the same time, the limiting piece 434 is limited by the movable groove 436 to prevent the hammer disc 32 from moving down too much and affecting the convenience of subsequent assembly, thereby fully improving the convenience of disassembly, replacement and reassembly. When the hammer disc 32 needs to be replaced, the spindle 1 and the upper cover 21 are disassembled, and then the top limiting seat 41 and the hammer disc 32 are moved up and disassembled from top to bottom, and then the hammer disc 32 and the hammer head 31 can be directly replaced as a whole, or the hammer disc 32 can be replaced. The hammer head 31 is removed and the hammer disc 32 is replaced separately. Here, the limit member 434, the limit locking member 433 and the hammer disc 32 can be replaced as an integrated replacement unit. In summary, the replacement of the hammer head 31 and the hammer disc 32 does not require the disassembly and assembly of a large number of fasteners, which effectively improves the efficiency and convenience of disassembly and replacement. Among them, the limited movement range of the moving groove 436 corresponding to the upper limit member 434 of the hammer disc 32 gradually increases from top to bottom. Due to the removal of the bottom limit seat 42 and the process of replacing the hammer head 31, in order to make the mounting hole 432 and the corresponding limit locking member 433 be aligned, the mounting hole 432 is fixed to the upper limit seat 434 of the hammer disc 32. 33 is separated, and the distance that the hammer disc 32 needs to move downward from top to bottom gradually increases. Therefore, the moving range of the upper limit member 434 on the hammer disc 32 also gradually increases from top to bottom, and the moving range of the limit of the corresponding moving groove 436 also gradually increases accordingly. On the basis of ensuring that the hammer disc 32 moves downward to fully separate the mounting hole 432 and the limit locking member 433, the moving groove 436 and the corresponding limit member 434 are fully adapted, and the moving groove 436 passes through the middle limit seat 435 upward, and the limit member 434 can directly slide into the moving groove 436 from top to bottom, thereby improving the convenience of disassembly and assembly.

[0026] See also Figure 2 A support connecting frame 23 is fixedly installed in the cylinder 22, and the bottom limit seat 42 is rotatably connected to the support connecting frame 23. When the hammer head 31 needs to be replaced, the bottom limit seat 42 is removed synchronously during the process of disassembling the cylinder 22. There is no need to disassemble the cylinder 22 first and then disassemble the bottom limit seat 42, which further simplifies the disassembly steps and improves the efficiency and convenience of disassembly and assembly.

[0027] See also Figure 3A limiting groove 44 is provided on the bottom limiting seat 42, and a limiting block 45 is connected to the hammer disc 32 adjacent to the bottom limiting seat 42. The limiting block 45 is inserted into the limiting groove 44, so that the bottom limiting seat 42 is stably connected to the hammer disc 32 and the two are easy to disassemble.

[0028] See also Figure 4 and Figure 6 The mounting groove 431 is eccentrically arranged. After the hammer head 31 is inserted into the corresponding mounting groove 431 and fixedly connected with the hammer disc 32, during the rotation of the main shaft 1, the hammer head 31 is subjected to the reaction force of the quartz stone and will generate potential energy to be inserted into the mounting groove 431, thereby strengthening the connection state between the hammer head 31 and the hammer disc 32 and improving the stability of the overall structure.

[0029] See also Figure 4 The mounting hole 432 is a waist-shaped structure, and the limiting locking piece 433 is also a waist-shaped structure. After the limiting locking piece 433 is inserted into the corresponding mounting hole 432, it can effectively limit the hammer head 31. Combined with the limiting of the hammer head 31 by the mounting groove 431, the hammer head 31 and the hammer disc 32 are stably and reliably connected together.
