[0002] Kaolin is a common and very important clay mineral in nature. It is clay and clay rock mainly composed of kaolinite clay minerals. It has many uses, mainly including industrial applications and skin care applications. Kaolin ore often contains large particles and impurities. When using kaolin, it is necessary to crush and remove impurities. Kaolin has a wide range of applications, and its mesh size classification has an important influence on its application performance. After the kaolin is crushed, it needs to be screened with different mesh sizes according to the different application requirements in various fields.

[0003] After searching for the invention patent with patent number CN116637676B, an automatic screening crusher is disclosed, which includes: crushing rollers, which are in a group and symmetrically and movably arranged in an upper box body; a power element, which is arranged on the upper box body and its output end is connected to the crushing rollers; a counterweight block, each of the crushing rollers is provided with a counterweight block at the eccentric position; a screening system, which is arranged between the upper box body and the lower box body; the whole device has a high degree of automation, and there is no need for manual screening by staff at a later stage, which reduces the input of labor.

[0004] The kaolin processing crusher used in the above patents and prior art background still has certain disadvantages, such as: 1. In the above patent, a screening system is arranged between the upper box and the lower box, and screening is performed through the screen. However, the above patent is similar to the existing crusher, and the screening structure function is relatively single. The setting of a single screen cannot meet the use requirements of screening and classification, which affects the scope of application; 2. In the above patent, air is input into the drive box through the telescopic tube through the connecting structure to control the reciprocating motion of the No. 1 piston in the drive box, driving the screen to reciprocate for screening. However, relying solely on the reciprocating translational sliding of the screen, the material can only roll on the screen, and cannot achieve shaking in three-dimensional space during the screening process, that is, it cannot expand the movement trajectory of the material, and it is easy for the material to be stuck in the mesh of the screen, causing the screen to be blocked and affecting the pass rate; Therefore, we propose a crusher for kaolin processing which can be screened and classified, so as to solve the above problems.

Through the setting of the linkage structure, the overall structure of the kaolin crusher is effectively optimized, and the screens can cooperate to perform double screening movements, which is more convenient to operate.

Since a feed port connected to the box cavity is provided at the center of the upper side shell wall of the crushing box shell 1, wherein an integrated structure of the silo is provided at the feed port, the kaolin block material is poured into the box cavity of the crushing box shell 1 through the silo; Since the crushing assembly 3 is similar in structure to the existing hammer crusher, it is composed of a combination of a hammer head and a rotor, wherein the hammer heads are arranged on the rotor at equal intervals in a rotating state, and an integrated shaft column is arranged at the center position of the rotor in the crushing assembly 3, and the left and right ends of the shaft column are fixedly clamped with bearings. After installation, the two ends of the shaft column are respectively connected with the bearings and movably plugged into the cavity walls on both sides of the crushing box shell 1. Since the output end of the crushing motor 4 is horizontally facing left after installation, it is fixedly installed on the right side wall of the crushing box shell 1 by bolts, and its output end is fixedly clamped on the right end of the shaft column of the crushing assembly 3, the crushing motor 4 is started to operate, so that the crushing assembly 3 is assisted by the bearing to rotate in the box cavity of the crushing box shell 1, and the kaolin block material is crushed by the hammer head therein; Since a discharge port connected to the box cavity is provided at the center of the lower shell wall of the crushing box shell 1, wherein the discharge port is arranged in a screen-like structure, and an integrated hopper is arranged at the discharge port, the crushed kaolin blocks are initially screened through the discharge port in the crushing box shell 1 and enter the hopper; Since the upper and lower sides of the crushing component 3 are both provided with an integrated scraper part 5, the scraper part 5 is arranged in a "U"-shaped structure, it is in a vertical state on the rotor in the crushing component 3, and it and the crushing component 3 constitute a synchronous rotation structure, and since the transverse plate body in the scraper part 5 is connected to the box cavity wall of the crushing box shell 1 in a fitting manner, during the crushing of kaolin blocks, the crushing component 3 drives the scraper part 5 to rotate synchronously, so that the transverse plate body in the scraper part 5 slides in contact with the box cavity wall of the crushing box shell 1, and the kaolin crushed materials that have not passed through the discharge port in the crushing box shell 1 are moved and transported, thereby assisting in secondary crushing.

[0022] When the kaolin crushed material is screened once by the double-selection screening mechanism 2, specifically, according to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.12 As shown, the screening box shell 6 is fixedly connected to the bearing frame in the crushing box shell 1 by bolts, and is provided with a first chamber, a second chamber and a third chamber in sequence from the inside to the outside, and the second chamber is connected and arranged below the first chamber, and the third chamber is connected and arranged below the second chamber. Since the first chamber in the screening box shell 6 is arranged in a circular structure, a feed port connected to it is provided at the left end of the upper wall of the first chamber, and since the conveying pipe 7 is arranged in the first chamber in the screening box shell 6 in an inclined rightward state after being arranged, its upper end outlet is clamped and fixedly connected to the feed port in the screening box shell 6 by bolts, and extends upwardly, and its lower end outlet is opposite to the discharge port of the first chamber in the screening box shell 6, corresponding to the right end of the first screen member 12, and since the upper end outlet of the conveying pipe 7 is connected and arranged to be connected with the hopper in the crushing box shell 1 by plugging, the kaolin crushed materials in the hopper in the crushing box shell 1 slide into the first chamber in the screening box shell 6 through the conveying pipe 7; Since the central position of the sector gear 18 is provided with an integrated shaft column, wherein the left and right ends of the shaft column are fixedly connected with bearings, the sector gear 18 is placed in a movable state in the groove cavity of the upper end box wall of the screening box shell 6 after being placed, and the two ends of the shaft column are respectively connected with bearings and inserted into the groove cavity walls on both sides. In addition, since the screening motor 19 is fixedly installed on the outer box wall of the screening box shell 6 by bolts after being placed, its output end is arranged horizontally facing left, and the output end is fixedly connected with the right end of the shaft column of the sector gear 18. When the screening motor 19 is started to operate, the sector gear 18 is assisted by the bearing to rotate on the upper end box wall of the screening box shell 6; Since the first arc frame 16 is movably inserted and clamped in the cavity wall slot of the first chamber in the screening box shell 6 after being installed, the arc center thereof coincides with the circle center of the first chamber in the screening box shell 6, and since the rear section of the first arc frame 16 is provided with a first toothed ring portion 1601 having the same arc center thereof, the first toothed ring portion 1601 is connected to the fan-shaped gear 18 in a meshing manner, and the arc size thereof is equal to the maximum sliding distance size of the first arc frame 16, after the fan-shaped gear 18 is driven to rotate, when the fan-shaped gear 18 is meshed and connected with the first toothed ring portion 1601, the meshing action between the two causes the first arc frame 16 to slide on the cavity wall of the first chamber in the screening box shell 6; Since spring bins are provided at both the left and right ends of the first arc frame 16, wherein a through-running slot is provided in the spring bin, a limiting column is clamped on the cavity wall of the first cavity in the screening box shell 6 and fixedly connected by bolts, after the first arc frame 16 is installed, the limiting column of the first cavity in the screening box shell 6 movably passes through the slot and extends into the spring bin, and since a first arc spring 17 is installed at the connection between the first arc frame 16 and the screening box shell 6, the first arc spring 17 is symmetrically arranged about the horizontal center axis of the first arc frame 16, and after installation, it is movably inserted into the spring bin of the first arc frame 16, one end of which is pressed against the limiting column of the first cavity in the screening box shell 6, and the other end of which is pressed against The first arc frame 16 is pressed against the spring chamber wall of the first arc frame 16. After the first arc frame 16 is driven to slide, the limiting column of the first chamber in the screening box shell 6 forms a sliding structure in the spring chamber of the first arc frame 16, and the first arc spring 17 is squeezed and elastically deformed. When the fan gear 18 rotates and loses the meshing connection with the first gear ring part 1601, the elastic deformation of the first arc spring 17 is used to reset the first arc frame 16 to reset and slide on the chamber wall of the first chamber in the screening box shell 6, that is, the meshing cooperation between the fan gear 18 and the first gear ring part 1601 and the elastic deformation of the first arc spring 17 are used to operate the first arc frame 16 to slide back and forth; Since the first screening frame 11 is arranged in a square frame structure, its longitudinal section is an arc structure, and its arc center coincides with the circle center of the first chamber in the screening box shell 6, after the first arc frame 16 is arranged, its two ends are overlapped and fixedly connected to the front and rear side frame walls of the first screening frame 11 by bolts, and after the first arc frame 16 is driven to slide back and forth, it drives the first screening frame 11 to move synchronously; Since the second chamber in the screening box shell 6 is arranged in an arc-shaped structure, the center of the arc coincides with the center of the circle of the first chamber, the first screening frame 11 is provided with an inner guide plate of an integrated structure toward the inside, wherein the longitudinal section of the inner guide plate is arranged in an arc-shaped structure, and the first screening frame 11 is provided with an outer guide plate of an integrated structure toward the outside, wherein the longitudinal section of the outer guide plate is arranged in an arc-shaped structure, and the first screening frame 11 and the inner guide plate and the outer guide plate are arranged at the same arc center, and since the first screening frame 11 is arranged and movably inserted into the connecting port between the first chamber and the second chamber in the screening box shell 6, wherein the inner guide plate is movably arranged in the first chamber, and wherein the outer guide plate is movably arranged in the second chamber, the first screening frame 11 is arranged in an active positioning state, and the first screening frame 11 is driven to swing and rotate in the first chamber of the screening box shell 6; Since the specification and size of the inner guide plate in the first screening frame 11 are compatible with the specification and size of the first chamber in the screening box shell 6, a sealing ring is fixedly connected around the inner guide plate, and the inner guide plate and the sealing ring are sealed and fitted with the cavity wall of the first chamber in the screening box shell 6.

Since the arc length of the inner guide plate in the first screening frame 11 is greater than the arc length of the connecting port between the first chamber and the second chamber in the screening box shell 6, a sealing treatment is performed at the connection between the first screening frame 11 and the screening box shell 6. Since the first screen member 12 is arranged in the frame cavity of the first screening frame 11, the first screening frame 11 drives the first screen member 12 to form a synchronous motion structure. When the first screening frame 11 is driven to swing back and forth, the first screen member 12 is driven to swing back and forth synchronously, so as to shake and screen the kaolin crushed material.
