[0030] The technical solutions of the present invention are described below with reference to the accompanying drawings. It is also noted that, to provide a more detailed description, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for certain known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0031] like Figures 1 to 8 As shown, the embodiment of the present invention provides an automated crushing device for rare earth oxide production, comprising a crushing drum 1, a filter plate 9 is provided on the lower side of the crushing drum 1, a guide plate 10 is provided obliquely on one side of the crushing drum 1, and a square tube 2 (such as Figure 4 As shown in FIG, one end of the square tube 2 is rotatably connected to the inner end of the crushing drum 1 through a bearing 11, and multiple crushing rods 3 with sharp teeth are rotatably inserted on both sides of the square tube 2, and a linkage mechanism is included to drive the multiple crushing rods 3 to rotate; it also includes two crushing mechanisms for crushing large pieces of material; the crushing mechanism includes a hollow shovel plate 101 fixed to the outside of the square tube 2, and a main shaft 102 (as shown in FIG) is rotatably connected to the inside of the hollow shovel plate 101. Figure 6 As shown in FIG, a support rod 103 is fixed to the inner side of the hollow shovel plate 101, and a plurality of knocking mechanisms are also included. Two large gears 115 are fixed to the two ends of the inner side of the crushing cylinder 1, and two small gears 114 are fixed to the two ends of the main shaft 102. The two small gears 114 are respectively engaged with the two large gears 115; the knocking mechanism includes a cam 104 rotatably sleeved on the outside of the main shaft 102 and having a plurality of raised ends, a rotating arm 105 rotatably connected to the outside of the support rod 103, and a striker 106 movably inserted on the upper side of the hollow shovel plate 101. One end of the rotating arm 105 is elastically connected to the inner side of the hollow shovel plate 101 by a knocking spring 112. The other end of the rotating arm 105 is rotatably connected to the roller 113; it also includes multiple clutch mechanisms that combine the cam 104 with the main shaft 102 after detecting large pieces of material; the driving mechanism includes a transmission housing 4 fixed to one end of the outer side of the crushing cylinder 1, and the inner side of the transmission housing 4 is located at the center position and is rotatably connected to a drive shaft 8 extending to the inside of the crushing cylinder 1, and a main motor 5 is installed on the outside of the transmission housing 4, and the driving end of the main motor 5 is fixed to a worm 6 located on the inner side of the transmission housing 4, and a worm wheel 7 meshing with the worm 6 is fixed to the outer end of the drive shaft 8, and one end of the drive shaft 8 is fixedly connected to one end of the square tube 2.

[0032] Furthermore, the two ends of the knock spring 112 are respectively connected to a sleeve rod 110 and a slide rod 111. The slide rod 111 is slidably inserted into one end of the inner side of the sleeve rod 110. The other end of the sleeve rod 110 is rotatably connected to the inner side of the hollow shovel plate 101. One end of the slide rod 111 is rotatably connected to one end of the rotating arm 105. When the rotating arm 105 rotates to compress the knocking spring 112, the knocking spring 112 can store elastic potential energy. When one end of the rotating arm 105 loses the support of the raised end of the cam 104, the knocking spring 112 can quickly release the elastic potential energy, thereby knocking the lower end of the striker 106. The striker 106 transmits the impact force to the large piece of material, thereby crushing the large piece of material.

[0033] Furthermore, a striker convex ring 108 is fixed at the middle position of the striker 106, and a striker sleeve 107 is provided on the outer sliding sleeve of the striker convex ring 108. The striker sleeve 107 is fixed to the inner side of the hollow shovel plate 101, and the lower end of the striker convex ring 108 is elastically connected to the inner lower end of the striker sleeve 107 through a first spring 109; Through the sliding fit between the striker convex ring 108 and the striker sleeve 107, the striker 106 can move along a straight track. When the striker 106 is impacted, more impact kinetic energy can be transferred to the material, thereby improving the crushing effect.

[0034] Furthermore, one side of each raised end on the outside of the cam 104 is an arc-shaped surface, and the other side of each raised end on the outside of the cam 104 is a vertical surface that coincides with the diameter of the main shaft 102; When the cam 104 rotates, the curved surface of the raised end can apply thrust to the roller 113, thereby pushing the rotating arm 105 to rotate. The rotation of the rotating arm 105 compresses the knocking spring 112. After compression, the knocking spring 112 can store elastic potential energy. When the roller 113 separates from the curved surface, the elastic potential energy of the knocking spring 112 can be released instantly, driving one end of the rotating arm 105 to knock the lower end of the striker 106.

[0035] Furthermore, the clutch mechanism includes a plurality of first limit blocks 202 fixed to one end of the cam 104 and arranged in a circle, a slip ring 201 slidably sleeved on the outside of the main shaft 102, and a hydraulic transmission mechanism that drives the slip ring 201 to slide on the outside of the main shaft 102, one end of the slip ring 201 is fixed with a plurality of second limit blocks 203 arranged in a circle, the hydraulic transmission mechanism includes a first piston cylinder 205 fixed to the inside of the hollow shovel plate 101, a second piston cylinder 208 fixed on the upper side of the hollow shovel plate 101 near the striker 106, the inner side of the second piston cylinder 208 is slidably connected to the second piston plate 212, and one end of the second piston plate 212 is fixed with a second piston rod 209 extending to the outside, A first piston plate 207 is slidably connected to the inner side of a piston cylinder 205, and a first piston rod 206 extending to the outside is fixed to one end of the first piston plate 207. A collar 204 is fixed to one end of the first piston rod 206, and one end of the collar 204 is rotatably sleeved on the outer side of the sliding ring 201. The first piston cylinder 205 and the second piston cylinder 208 are connected through a connecting pipe 214. The other end of the second piston plate 212 is elastically connected to the inner end of the second piston cylinder 208 through a second spring 213. A pressing frame 211 is rotatably connected to the upper side of the hollow shovel plate 101 at a position corresponding to the second piston rod 209. The pressing frame 211 is movably connected to the upper end of the second piston rod 209 through a connecting rod 210. When there is a large piece of material at any position above the hollow shovel plate 101, the hydraulic transmission mechanism at the corresponding position will be triggered under the action of the material pressure, thereby triggering the clutch mechanism at the corresponding position, and the cam 104 at the corresponding position will be combined with the main shaft 102 through the clutch mechanism at the corresponding position, thereby driving a knocking mechanism at the corresponding position to operate, and the knocking mechanism is operated to crush the large piece of material. Since other positions on the upper side of the hollow shovel plate 101 are not pressed by the large piece of material, the knocking mechanism at other positions does not move, and the cam 104 at other positions does not rotate, so the operating load of the device can be reduced, further improving the operating stability of the device, and increasing the operating speed and crushing efficiency.

[0036] Furthermore, the linkage mechanism includes a plurality of linkage gears 304 fixed to one end of each crushing rod 3, two second bevel gears 303 fixed to one end of the two crushing rods 3 at the end, a first bevel gear 302 is meshed between the two second bevel gears 303, one end of the first bevel gear 302 is fixed to one end of the inner side of the crushing cylinder 1 through a fixed shaft 301, and two adjacent linkage gears 304 are meshed with each other through teeth; Through the action of the linkage mechanism, when multiple crushing bars 3 rotate around the axis of the crushing barrel 1, they can also rotate on their own, and the rotation direction of each adjacent crushing bar 3 is opposite. When multiple crushing bars 3 rotate on their own, the multiple sharp teeth on the outside can crush the materials located near the crushing bars 3, thereby achieving a uniform crushing effect. It can crush small and medium-sized materials. In conjunction with the crushing mechanism, it can achieve the simultaneous crushing of large, medium and small materials, while ensuring stability and improving crushing efficiency.

[0037] Working principle: When in use, the rare earth oxides to be crushed are poured onto the upper surface of the guide plate 10, and the materials slide along the upper surface of the guide plate 10 to the inner side of the crushing drum 1. At the same time, the main motor 5 controlling the driving mechanism drives the worm 6 to rotate, the worm 6 drives the worm gear 7 to rotate, the worm gear 7 drives the driving shaft 8 to rotate, and the driving shaft 8 drives the square tube 2 to rotate. One end of the square tube 2 is rotatably connected to the inner end of the crushing drum 1 through the bearing 11, so the square tube 2 can rotate stably around the axis of the crushing drum 1, and the square tube 2 can drive multiple crushing rods 3 on both sides thereof to rotate around the axis of the crushing drum 1. Since the first bevel gear 302 and the fixed shaft 301 in the linkage mechanism are fixed and do not rotate, the two second bevel gears 303 will be driven to rotate around the first bevel gear 303 when the square tube 2 rotates. The outer side of a bevel gear 302 rotates, and the meshing between the two second bevel gears 303 and the first bevel gear 302 can drive the two second bevel gears 303 to rotate. The two second bevel gears 303 respectively drive the two crushing bars 3 to rotate. At the same time, the meshing between each adjacent linkage gear 304 can drive the adjacent crushing bars 3 to rotate. By analogy, multiple crushing bars 3 can be driven to rotate at the same time, and the rotation directions of each adjacent crushing bar 3 are opposite. When the multiple crushing bars 3 rotate, the multiple sharp teeth on the outer side can crush the materials near the crushing bars 3, thereby achieving the effect of uniform crushing. After crushing, the materials are formed into small-sized particles, which can eventually leak out through the small holes on the filter plate 9 under the action of gravity. When there are large and relatively hard rare earth oxides, it is difficult to crush them by rotating multiple crushing rods 3 alone. Therefore, a crushing mechanism is set to impact the large pieces of material. When the large piece of material is at any position on the upper side of the hollow shovel plate 101, the large piece of material will exert downward pressure on the pressing frame 211 at this position. After the pressing frame 211 is under pressure, it presses the second piston rod 209 of the hydraulic transmission mechanism through the connecting rod 210, so that the second piston rod 209 moves toward the inside of the second piston cylinder 208 and drives the second piston plate 212 to move downward. At the same time, the second spring 213 is compressed. The downward movement of the second piston plate 212 can press the hydraulic oil at the lower end of the inner side of the second piston cylinder 208 into one end of the inner side of the first piston cylinder 205 through the connecting pipe 214. The hydraulic oil pushes the first piston plate 207, and the first piston plate 207 drives the first piston rod 206 to move outward. The first piston rod 206 pushes the ring 204 to move, and the ring 204 pushes the slip ring 2 01 moves on the outside of the main shaft 102, so that the slip ring 201 approaches the cam 104 until the multiple second limit blocks 203 at one end of the slip ring 201 engage with the multiple first limit blocks 202 at one end of the cam 104. It should be noted that the slip ring 201 is arranged on the outside of the main shaft 102 through a spline sliding sleeve. Therefore, the slip ring 201 can only slide linearly on the outside of the main shaft 102 and cannot rotate on the outside of the main shaft 102. At this time, the main shaft 102 can transmit the rotation torque to the cam 104 through the slip ring 201, the second limit block 203, and the first limit block 202. When the square tube 2 drives the crushing mechanism to rotate, the two small gears 114 therein rotate along the outsides of the two large gears 115 respectively and mesh with each other, thereby driving the two small gears 114 to rotate, and the two small gears 114 drive one main shaft 102 to rotate. When the main shaft 102 rotates, the cam 104 can be driven to rotate. The rotation direction of the cam 104 is counterclockwise, such as Figure 8 As shown; Since the cam 104 is provided with a plurality of raised ends on the outside, and one side of each raised end on the outside of the cam 104 is an arcuate surface, and the other side of each raised end on the outside of the cam 104 is a vertical surface coinciding with the diameter of the main shaft 102, when the cam 104 rotates counterclockwise, one end of the rotating arm 105 is rotatably connected to the roller 113, and the roller 113 can roll along the arcuate surface of each raised end, and the arcuate surface applies an upward thrust to the roller 113, thereby driving the rotating arm 105 to rotate clockwise by a certain angle, such as Figure 8As shown, the end of the rotating arm 105 close to the striker 106 is rotated downward, and at the same time, the slide bar 111 is pushed into the inner side of the sleeve rod 110, and the knock spring 112 is compressed. When the cam 104 continues to rotate, the roller 113 separates from the top of the arc surface. At this time, the vertical surface on the other side of the protruding end does not provide support for the roller 113. The roller 113 is suspended in the air at the moment of separation from the top of the arc surface. At this time, under the elastic force of the knock spring 112, the rotating arm 105 is pushed to rotate in the opposite direction quickly, so that the end of the rotating arm 105 close to the striker 106 is rotated upward quickly. One end of the rotating arm 105 impacts the lower end of the striker 106, and the upper end of the striker 106 is conical. When the lower end of the striker 106 is impacted by the rotating arm 105, the impact force is transmitted to the bulk material through the cone at the upper end, so that the position where the bulk material contacts the cone at the upper end of the striker 106 is subjected to great pressure, so that the bulk material can be crushed more easily. After the bulk material is crushed into smaller-sized materials, it is crushed more finely by multiple crushing rods 3, and the crushing rod 3 can be prevented from getting stuck, thereby ensuring the stability of the device during crushing.
