[0024] Figures 1-6 This is the best embodiment of the present invention, Figures 1-6 The utility model is further described.

[0025] A ceramic raw material screening device includes a screening machine 1, two mounting rings 2 are provided inside the screening machine 1, a screening net 3 is fixedly connected to the inside of the mounting ring 2, a plurality of fixed blocks 4 are fixedly connected to the inside of the screening machine 1, a top groove 5 is provided on the top surface of the fixed block 4, a clamping groove 6 is provided on the inner circular wall surface of the top groove 5, a clamping column 9 is provided on the bottom surface of the mounting ring 2, the clamping column 9 is movably clamped with the clamping groove 6, a rotating component is provided on the top surface of the mounting ring 2 for rotating the clamping column 9, and a moving component is provided inside the top groove 5 for moving the clamping column 9.

[0026] Specifically, the rotating component includes: a top hole 7, which is opened on the top surface of the mounting ring 2, and a rotating bar 8 is provided inside the top hole 7, which is rotatably connected to the clamping column 9.

[0027] In this embodiment, by setting the clamping column 9, when the rotating bar 8 drives the clamping column 9 to move in the channel formed by the top groove 5 and the support block 13, the clamping column 9 can rotate on the rotating bar 8, thereby facilitating the movement of the clamping column 9.

[0028] Specifically, the rotating component further includes: two inner grooves 10, which are respectively opened on both sides of the interior of the top hole 7, and the interiors of the two inner grooves 10 are slidably connected with moving wheels 11, which are rotatably connected to the rotating bar 8.

[0029] In this embodiment, the rotating bar 8 can be rotated by the movable wheel 11 , so that the position of the clamping column 9 can be adjusted when the rotating bar 8 rotates.

[0030] Specifically, the rotating component further includes: two first return springs 12 , both of which are fixedly connected to the outer circumferential wall of the moving wheel 11 , and one end of the first return spring 12 is fixedly connected to the interior of the inner groove 10 .

[0031] In this embodiment, by setting the first return spring 12, when the rotating bar 8 drives the moving wheel 11 to move downward, the moving wheel 11 will squeeze the first return spring 12. When the rotating bar 8 is released, the first return spring 12 will be reset, and then the first return spring 12 will drive the moving wheel 11 and the rotating bar 8 to reset.

[0032] Specifically, the moving parts include: a support block 13, which is slidably connected to the inside of the top groove 5, and two second return springs 14 are fixedly connected to the bottom surface of the support block 13, and the second return springs 14 are fixedly connected to the inner bottom surface of the top groove 5. The moving parts also include: two limit grooves 15, and the two limit grooves 15 are both opened on both sides of the inside of the top groove 5.

[0033] In this embodiment, by setting the support block 13, when the support block 13 moves downward, the support block 13 drives the limit block 16 to slide inside the limit groove 15. The limit block 16 can ensure the stability of the movement of the support block 13 and prevent the support block 13 from shaking left and right when moving.

[0034] When the sieve 3 on the upper layer of the screening machine 1 needs to be replaced, the sieve 3 on the upper layer of the screening machine 1 is replaced. At this time, the rotating bar 8 is pressed downward, and the rotating bar 8 drives the moving wheel 11 to move downward inside the inner groove 10 and squeeze the first return spring 12, thereby allowing the clamping column 9 to move out of the inner groove 6 and give the support block 13 a downward squeezing force. At this time, the support block 13 will squeeze the second return spring 14, and then the staff can toggle the rotating bar 8 on the moving wheel 11 to rotate and drive the clamping column 9 to rotate until one side of the rotating bar 8 contacts the inner side of the top hole 7 and stops rotating due to the obstruction of the top hole 7. At this time, the mounting ring 2 and the screening machine 3 are pulled upward to drive the rotating bar 8 and the clamping column 9 to move out of the top groove 5, thereby achieving the disassembly effect of the screening machine 3, which is convenient for adapting to the needs of screening ceramic raw materials. The adaptability is stronger, and according to the above operation, the screening machine 1 The lower layer of the screening machine 1 can also be disassembled.

[0035] Through the provided rotating bar 8, when it is necessary to install the screening net 3 of the lower layer of the screening machine 1, the rotating bar 8 is rotated at this time, and then the rotating bar 8 drives the clamping column 9 to rotate until one side of the rotating bar 8 contacts the inner side of the top hole 7. At this time, the position of the clamping column 9 corresponds to the position of the top groove 5. Then the staff can place the mounting ring 2 on the fixed block 4. At this time, the clamping column 9 enters the channel formed by the top groove 5 and the support block 13. Then the staff presses the rotating bar 8 downward. At this time, the rotating bar 8 drives the moving wheel 11 to move downward inside the inner groove 10 and squeezes the first reset spring Spring 12, at this time the column 9 will squeeze the support block 13, and then the support block 13 moves downward inside the top groove 5 and squeezes the second return spring 14, and then continues to rotate the rotating bar 8 until the rotating bar 8 rotates to the vertical direction. At this time, the column 9 corresponds to the position of the slot 6, and then the potential energy of the second return spring 14 is released to drive the support block 13 to reset and squeeze the column 9 to the inside of the slot 6, and then the mounting ring 2 and the fixed block 4 can be assembled to achieve the installation effect of the screening mesh 3. According to the above operation, the screening mesh 3 on the upper layer of the screening machine 1 can also be installed.

[0036] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto.
