The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] First embodiment:

[0021] See also Figures 1 to 4 ,in Figure 1 This is the overall structural diagram of the high-efficiency crushing and screening device for clay lithium ore. Figure 2 is a schematic diagram of the structure of the screening component. Figure 3 yes Figure 2 A magnified image of Figure 4 It is a schematic diagram of the cam installation structure.

[0022] The utility model provides a clay lithium ore efficient crushing and screening device, comprising a housing 101, a crushing assembly 102 and a screening assembly 103, wherein the screening assembly 103 comprises a support plate 104, a screen plate 105, a baffle 106, a cam 107, a driving component 108 and a guide rod 109, wherein the baffle 106 comprises a seat body 112, a spring 113 and a plate body 114, and the driving component 108 comprises a motor seat 115, a driving motor 116, a driving wheel 117, a driven wheel 118 and a transmission belt 119, through the baffle 10 6. The time that the ore stays on the sieve plate 105 is increased, thereby improving the screening effect of the ore. At the same time, the sieve plate 105 is prevented from being blocked by the up and down vibration of the sieve plate 105. After the sieve plate 105 rises to the height of the top of the baffle plate 106, the ore is not blocked by the baffle plate 106, so that the ore can roll along the sieve plate 105, avoiding the accumulation of the ore on the sieve plate 105. It can be understood that the above scheme can be used to improve the screening effect of the ore, and can also be used to drive the cam 107 to rotate.

[0023] According to this specific embodiment, the crushing assembly 102 is disposed on the housing 101 , and a feed port and a discharge port are disposed on the housing 101 . The crushing assembly 102 is used to crush the ore.

[0024] The support plate 104 is fixedly connected to the housing 101 and is located inside the housing 101. The sieve plate 105 is slidably connected to the housing 101 and abuts against the support plate 104 and is located inside the housing 101. The baffle 106 is connected to the housing 101 and passes through the sieve plate 105 and is located inside the housing 101. The cam 107 is rotatably connected to the housing 101 and abuts against the sieve plate 105 and is arranged on the housing 101. The driving member 10 8 is arranged on the housing 101 and drives the cam 107 to rotate; the baffles 106 are provided with a plurality of them, a fine ore collection frame 110 is provided below the sieve plate 105, and a coarse ore collection frame 111 is provided at the discharge port of the housing 101; when in use, the ore to be crushed is put into the housing 101 through the feed port, the ore is crushed by the crushing assembly 102, the crushed ore falls on the sieve plate 105, and the crushed ore is screened by the sieve plate 105; through the plurality of baffles 10 6 blocks the movement of the ore, and at the same time drives the cam 107 to rotate through the driving member 108, so that the protrusion on the cam 107 periodically abuts against the screen plate 105, and then the screen plate 105 vibrates up and down under the action of the cam 107 and gravity. When the screen plate 105 rises to the height of the baffle 106, the baffle 106 cannot stop the ore from rolling down, and the ore can move along the screen plate 105. During the movement of the ore, the coarser ore falls into the coarse ore collection frame 111. Finer ore passes through the sieve plate 105 and falls into the fine ore collection frame 110, thereby completing the crushing and screening of the ore. The ore is blocked by the baffle 106 to increase the ore screening time and prevent the ore from directly rolling into the coarse ore collection frame 111. The sieve plate 105 not only avoids itself from being blocked during the lifting process, but also allows the ore to move along the sieve plate 105 after it moves above the baffle 106, thereby preventing ore accumulation and achieving the purpose of improving the ore screening effect.

[0025] Secondly, the guide rod 109 is fixedly connected to the support plate 104 and slidably connected to the sieve plate 105, and is located on the side of the support plate 104 close to the sieve plate 105; the movement of the sieve plate 105 is guided by the guide rod 109, so that the sieve plate 105 can only be raised and lowered along the direction of the guide rod 109, thereby improving the stability of the sieve plate 105 when it vibrates up and down.

[0026] At the same time, the seat body 112 is fixedly connected to the outer shell 101 and is located inside the outer shell 101; the spring 113 is connected to the seat body 112 and is located inside the seat body 112; the plate body 114 is connected to the spring 113, is slidably connected to the seat body 112, and passes through the screen plate 105; the spring 113 is elastic and can be retracted. When the ore hits the upper end of the plate body 114, the elasticity of the spring 113 is used to buffer the impact force, thereby preventing the plate body 114 from being deformed due to long-term hard collision with the ore.

[0027] In addition, the motor seat 115 is fixedly connected to the housing 101 and is located on one side of the housing 101; the drive motor 116 is connected to the motor seat 115 and is arranged on the drive motor 116; the driving wheel 117 is arranged on the drive motor 116 and is connected to the output end of the drive motor 116; the driven wheel 118 is fixedly connected to the cam 107 and is located on one side of the cam 107, and the transmission belt 119 is rotationally connected to the driving wheel 117 and the driven wheel 118, and is sleeved on both sides of the driving wheel 117 and the driven wheel 118; the driving motor 116 drives the driving wheel 117 to rotate, so that the driving wheel 117 drives the transmission belt 119 and the driven wheel 118 to rotate, and then drives the cam 107 to rotate, thereby achieving the purpose of driving the cam 107 to rotate.

[0028] When using the clay lithium ore efficient crushing and screening device of this embodiment, the ore is crushed by the crushing assembly 102, and the crushed ore falls on the sieve plate 105. The crushed ore is screened by the sieve plate 105, and the ore is blocked by the baffle 106 to increase the time the ore stays on the sieve plate 105, thereby increasing the screening effect; at the same time, the cam 107 is driven to rotate by the driving member 108, so that the sieve plate 105 vibrates up and down under the action of the cam 107 and gravity. When the sieve plate 105 rises to the upper end of the baffle 106, the ore is not blocked and can roll down along the sieve plate 105 at this time, thereby avoiding the accumulation of ore on the sieve plate 105, thereby achieving the purpose of improving the ore screening effect.
