Summary of the invention

[0005] The present invention is intended to provide a cement production grinding device to solve the problem that the existing device has no screening function for the ground cement particles.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cement production grinding device, comprising a box body, a feed port and a discharge port are provided on both sides of the box body along the width direction of the box body; a partition is provided in the box body, and a grinding mechanism is provided on both sides of the partition, the grinding mechanism comprises a rotating shaft rotatably connected to the box body, an arc plate fixed to the partition, and a grinding block is provided on the rotating shaft; the arc plate is fixed to the inner wall of the box body, a plurality of filter holes are provided on the arc plate, the arc plate is located below the grinding block, and the arc plate is located between the feed port and the discharge port; and also includes a driving mechanism for simultaneously driving the two rotating shafts to rotate.

[0007] The principles and advantages of this solution are: this solution introduces cement blocks into the box through the feed port so that the cement blocks are located on the arc plate; the driving mechanism drives the rotating shaft to rotate, and the rotating shaft drives the grinding block to swing, and the grinding block is used to grind the cement blocks to obtain cement particles; compared with the prior art, in this solution, if the size of the cement particles meets the standard, the cement particles pass through the filter holes and fall to the bottom of the box; if the size of the cement particles does not meet the standard, the cement particles stay on the arc plate and continue to be ground by the grinding block until the size of the cement particles meets the standard. Therefore, there is no need for manual screening, nor is there any need to manually transfer cement particles of unqualified size for secondary grinding, and the operation is simpler.

[0008] Furthermore, the driving mechanism includes a circular shaft rotatably connected to the box body, a transverse groove opened on the inner wall of the box body on both sides of the partition, a gear coaxially connected to the rotating shaft, and a driving part for driving the circular shaft to rotate, a cylindrical cam is coaxially connected to the circular shaft, a curved groove is provided on the cylindrical cam, and side blocks are slidably connected on both sides of the cylindrical cam in the curved groove; a rack is slidably connected in the transverse groove, the rack is fixed to the side block, the rack is meshed with the gear, and the movement directions of the two racks are opposite.

[0012] Through the above arrangement, during the transverse reciprocating motion of the rack, the rack drives the wall block to reciprocate transversely through the linkage block, and the wall block drives the two push blocks to reciprocate transversely, so that the two push blocks push the cement on the arc plate to move left and right, so that the grinding block can grind the cement on the arc plate to avoid cement accumulation at the left or right end of the arc plate, thereby ensuring comprehensive grinding of the cement and improving the conversion rate of the cement; and, during the transverse reciprocating motion of the two push blocks, the reciprocating swing of the grinding block will not be affected, that is, when the grinding block swings to the left, the two push blocks move to the left, and when the grinding block swings to the right, the two push blocks move to the right.

[0038] The specific implementation process is as follows:

[0039] When in use, small cement blocks are introduced into the box body 10 through the feed port so that the cement blocks are located on the arc-shaped plate 22 .

[0040] Start the motor 28, the output shaft of the motor 28 drives the worm 26 to rotate, the worm 26 engages with the worm wheel 27 to drive the worm wheel 27 to rotate, the worm wheel 27 drives the circular shaft 30 to rotate, the circular shaft 30 drives the cylindrical cam 33 to rotate, the cylindrical cam 33 drives the rack 35 to reciprocate laterally through the side block 34, so that both racks 35 can reciprocate laterally.

[0041] During the lateral reciprocating motion of the rack 35, the rack 35 meshes with the gear 32 to drive the gear 32 to rotate back and forth, the gear 32 drives the rotating shaft 21 to rotate back and forth, and the rotating shaft 21 drives the grinding block 23 to swing back and forth, so that the grinding block 23 acts on the cement block, thereby grinding the cement block to obtain cement particles; if the size of the cement particles meets the standard, the cement particles pass through the filter holes 24 and fall to the bottom of the box body 10. If the size of the cement particles does not meet the standard, the cement particles stay on the arc plate 22 and continue to be ground by the grinding block 23 until the size of the cement particles meets the standard.

[0042] During the transverse reciprocating motion of the rack 35, the rack 35 drives the wall block 42 to reciprocate laterally through the linkage block 43, and the wall block 42 drives the two push blocks 45 to reciprocate laterally, so that the two push blocks 45 push the cement on the arc plate 22 to move left and right, so that the grinding block 23 can grind the cement on the arc plate 22 to avoid cement accumulation at the left or right end of the arc plate 22, thereby ensuring comprehensive grinding of the cement and improving the conversion rate of the cement; and, during the transverse reciprocating motion of the two push blocks 45, the reciprocating swing of the grinding block 23 will not be affected, that is, when the grinding block 23 swings to the left, the two push blocks 45 move to the left, and when the grinding block 23 swings to the right, the two push blocks 45 move to the right.

[0044] During the rotation of the worm 26, the worm 26 drives the elliptical block 53 to rotate synchronously. When the two long-axis ends of the elliptical block 53 are respectively against the two guide blocks 50, the elliptical block 53 squeezes the two guide blocks 50 away, that is, the guide block 50 drives the outer plate 51 away from the box body 10, and the first spring 54 is compressed; when the two short-axis ends of the elliptical block 53 are respectively against the two guide blocks 50, the squeezing effect on the guide block 50 disappears, so that the guide block 50 moves in the opposite direction under the action of the first spring 54, that is, the two guide blocks 50 approach, and the guide block 50 drives the outer plate 51 to move synchronously, so that the outer plate 51 approaches the box body 10; therefore, the outer plate 51 can continuously approach and move away from the box body 10, that is, the outer plate 51 can reciprocate; during the reciprocating motion of the outer plate 51, the outer plate 51 drives the anti-blocking block 52 to reciprocate synchronously, so that the anti-blocking block 52 moves in the filter hole 24, thereby avoiding clogging of the filter hole 24.

[0046] After the cement particles fall to the bottom of the box body 10, they may be retained at the bottom of the box body 10, making it inconvenient to take them out from the discharge port 11; during the reciprocating motion of the outer plate 51, the outer plate 51 drives the movable plate 61 to reciprocate synchronously through the movable block 60, so that the two movable plates 61 are constantly approaching and moving away, thereby driving the cement particles at the bottom of the box body 10 to be centered, so that the cement particles are concentrated and located on the motion trajectory of the moving plate 64; when the moving plate 64 is away from the partition 20, the two movable plates 61 are approached, and the moving plate 64 is used to push the cement particles to move toward the discharge port 11, thereby promoting the removal of cement particles, avoiding the retention of cement particles, and improving the utilization rate of cement particles; when the moving plate 64 is close to the partition 20, the two movable plates 61 are away from each other to prepare for the next work.
