DETAILED DESCRIPTION

[0040] See also Figure 1-5 , the utility model provides a new technical solution: a cement raw material screening device, comprising a cement screening support frame 1, and wheels 2 are arranged at the four corners of the lower surface of the cement screening support frame 1;

[0041] Wherein, a mounting frame 3 is fixedly connected to the cement screening support frame 1;

[0042] Among them, two supporting blocks 4 are fixedly connected to the upper surface of the installation frame 3;

[0043] Among them, a slag discharge mechanism is provided on the support block 4;

[0044] Among them, a screening mechanism is arranged on the cement screening support frame 1 .

[0045] Furthermore, the slag discharge mechanism includes a rotating shaft 5, which is rotatably connected to the outer surfaces of the two adjacent sides of the two support blocks 4;

[0046] The left end of the rotating shaft 5 rotates and passes through the left surface of the left supporting block 4;

[0047] Among them, a fixing box 14 is fixedly connected to the installation frame 3, and the left end of the rotating shaft 5 rotates and penetrates into the fixing box 14;

[0048] The left end of the rotating shaft 5 is fixedly sleeved with a worm gear 11 .

[0049] Furthermore, a worm 12 is meshingly connected to the worm wheel 11, and the worm 12 is located in the fixing box 14;

[0050] The upper end of the worm 12 rotates and passes through the upper surface of the fixing box 14, the upper surface of the fixing box 14 is fixedly connected with the first motor 13, and the rotating output shaft of the first motor 13 is fixedly connected with the upper end of the worm 12;

[0051] The outer surface of the rotating shaft 5 is slidably sleeved with a connecting block 6 , and the outer surface of the connecting block 6 is fixedly connected with a cement screening frame 7 , which is matched with the mounting frame 3 .

[0052] Further, the lower surface of the cement screening frame 7 is in contact with and slidably connected to the upper surface of the mounting frame 3;

[0053] Among them, the inner wall of the cement screening frame 7 is fixedly sleeved with a cement screening net 8;

[0054] There are two springs 15 disposed between the two supporting blocks 4 and the connecting block 6 , and the two springs 15 are both sleeved on the outer surface of the rotating shaft 5 .

[0055] Furthermore, the outer surface of the connection block 6 is provided with a positioning groove 9 extending into the interior thereof;

[0056] The outer surface of the rotating shaft 5 is fixedly connected with a positioning block 10 , and the outer surface of the positioning block 10 on one side away from the rotating shaft 5 extends out of the outer surface of the connecting block 6 through the positioning groove 9 , and the positioning block 10 is slidably connected to the positioning groove 9 .

[0057] Further, the screening mechanism includes a motor frame 16, and the motor frame 16 is fixedly connected to the cement screening support frame 1;

[0058] Wherein, a second motor 17 is installed on the motor frame 16;

[0059] Wherein, the rotation output shaft of the second motor 17 is fixedly connected with a connecting rod 18;

[0060] A cam 19 is fixedly sleeved on one end of the connecting rod 18 away from the second motor 17 , and an outer surface of the cam 19 is slidably connected to a left side surface of the cement screening frame 7 .

[0061] Furthermore, in the initial state, the lower surface of the cement screening frame 7 is in contact with the upper surface of the mounting frame 3. When the screening mechanism of the device is started, the second motor 17 needs to be started. The second motor 17 starts to drive the connecting rod 18 to rotate. The rotation of the connecting rod 18 synchronously drives the cam 19 to rotate. During the rotation of the cam 19, its protruding end will contact the left surface of the cement screening frame 7 and give the cement screening frame 7 a thrust, thereby pushing the cement screening frame 7 to move away from the cam 19. The displacement of the cement screening frame 7 synchronously drives the connecting block 6 and the cement screening net 8 to move synchronously. The displacement of the connecting block 6 squeezes the right spring 15 to cause the spring 15 to be squeezed and deformed. When the cam 19 rotates until its protruding end is no longer in contact with the cement screening frame 7 When the second motor 17 rotates one circle, it drives the cement screening frame 7 to move left and right once, and then the second motor 17 starts to drive the cement screening frame 7 to vibrate left and right, so that the cement raw material is placed in the cement screening frame 7. By starting the second motor 17 to make the cement screening frame 7 vibrate left and right, the sand can be screened through the cement screening net 8, and the sand particles with large particles or clumping in the sand can be screened out, so that there is no need for manual screening, which saves manpower and improves the efficiency of cement raw material screening, thereby improving the user experience of the device.

[0062] Furthermore, the sliding connection between the positioning groove 9 and the positioning block 10 connects the connecting block 6 and the rotating shaft 5, so that the connecting block 6 can be displaced left and right and can rotate synchronously with the rotation of the rotating shaft 5, thereby meeting the needs of the slag discharge mechanism and the screening mechanism at the same time, ensuring the stability of the operation of the slag discharge mechanism and the screening mechanism, and thus improving the stability of the device.

[0063] Furthermore, when the screening is completed and the sand particles with larger particles or clumping in the sand in the cement screening frame 7 need to be discharged, the device is pushed to a suitable position. At this time, the first motor 13 is started again, and the first motor 13 starts to drive the worm 12 to rotate. The rotation of the worm 12 synchronously drives the worm wheel 11 to rotate. The rotation of the worm wheel 11 synchronously drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 synchronously drives the positioning block 10 to rotate. The rotation of the positioning block 10 synchronously drives the connecting block 6 to rotate. The rotation of the connecting block 6 synchronously drives the cement screening frame 7 to rotate, and then drives the cement screening frame 7 to rotate and flip. When the cement screening frame 7 rotates to a suitable angle, all the sand particles with larger particles or clumping in the sand in the cement screening frame 7 can be dumped out, so that large particles of impurities can be quickly concentrated and processed, and there is no need to manually remove some clumping and large particles of impurities in the sand, which saves manpower while improving the cleaning efficiency of the device, thereby simultaneously improving the screening efficiency of the cement raw materials, thereby improving the practicability of the device, and optimizing the use experience of the device.

[0064] Furthermore, the wheels 2 facilitate movement of the entire device, thereby increasing the stability of the device.

[0065] Furthermore, in this solution, the rotation of the second motor 17 can only drive the cement screening frame 7 to vibrate left and right with a smaller amplitude and higher frequency.

[0066] Working principle: when the device is used, in the initial state, the lower surface of the cement screening frame 7 contacts with the upper surface of the mounting frame 3. When the screening mechanism of the device is started, the second motor 17 needs to be started. The second motor 17 starts to drive the connecting rod 18 to rotate. The rotation of the connecting rod 18 synchronously drives the cam 19 to rotate. During the rotation of the cam 19, its protruding end will contact with the left surface of the cement screening frame 7 and give the cement screening frame 7 a thrust, thereby pushing the cement screening frame 7 to move away from the cam 19. The displacement of the cement screening frame 7 synchronously drives the connecting block 6 and the cement screening net 8 to move synchronously. The displacement of the connecting block 6 squeezes the right spring 15 to cause the spring 15 to be squeezed and deformed. When the cam 19 rotates until its protruding end is no longer in contact with the cement When the screening frame 7 is in contact, the cement screening frame 7 will be pushed to move towards the direction close to the cam 19 under the action of the released elastic force of the right spring 15, and then reset. Then, every time the second motor 17 rotates one circle, it will drive the cement screening frame 7 to reset left and right once, and then the second motor 17 will start to drive the cement screening frame 7 to vibrate left and right, and then the sand will be placed in the cement screening frame 7. By starting the second motor 17 to make the cement screening frame 7 vibrate left and right, the sand can be screened through the cement screening net 8, and the sand particles that are clumped or larger in the sand can be screened out, so that there is no need for manual screening, which saves manpower and improves the efficiency of cement raw material screening, thereby improving the user experience of the device.

[0067] Furthermore, when the screening is completed and the sand particles that are clumped or have larger particles in the sand in the cement screening frame 7 need to be discharged, the first motor 13 is started at this time, and the first motor 13 starts to drive the worm 12 to rotate, and the rotation of the worm 12 synchronously drives the worm wheel 11 to rotate, and the rotation of the worm wheel 11 synchronously drives the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 synchronously drives the positioning block 10 to rotate, and the rotation of the positioning block 10 synchronously drives the connecting block 6 to rotate, and the rotation of the connecting block 6 synchronously drives the cement screening frame 7 to rotate, and then drives the cement screening frame 7 to rotate and flip, and when the cement screening frame 7 rotates to a suitable angle, all the sand particles that are clumped or have larger particles in the sand in the cement screening frame 7 can be dumped out, and there is no need to manually remove some clumping and large particle impurities in the sand, which saves manpower while improving the cleaning efficiency of the device, thereby simultaneously improving the screening efficiency of the cement raw materials, thereby improving the practicability of the device, and optimizing the use experience of the device.
