DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] See also Figures 1 to 6 A cement grinding production device with a shock-absorbing function comprises a machine body 1, a motor 3, a grinding roller 9, a screen 10 and a discharge port 11 are arranged inside the machine body 1, and a feeding port 2 is evenly and evenly inlaid on the top of the machine body 1;

[0031] The shaft output end of the motor 3 is fixedly connected to the grinding roller 9, and the cement grinding activity is achieved through the rotation of the grinding roller 9.

[0032] Particles reaching the desired particle size fall through the screen 10 and are then discharged from the machine body 1 through the discharge port 11 and can be collected manually.

[0033] A mixing plate 5 is fixedly installed inside the machine body 1, and a mixture outlet 12 is provided at both ends of the mixing plate 5;

[0034] Different materials enter the body 1 through different feeding ports 2. Preferably, pipeline transportation can be adopted, and an electric control valve can be added to the pipeline to achieve precise control.

[0035] Different materials fall on different positions of the mixing plate 5 respectively. Under the action of gravity, some of the materials gather toward the center of the mixing plate 5 to achieve preliminary mixing.

[0036] A rotating shaft 6 is rotatably mounted inside the machine body 1, a connecting plate 7 is fixedly mounted on the rotating shaft 6, a rubber scraper 13 is fixedly mounted on the connecting plate 7, and the rubber scraper 13 directly contacts the surface of the mixing plate 5;

[0037] The rotation of the rotating shaft 6 can drive the connecting plate 7 to rotate, and the rubber scraper 13 is in direct contact with the surface of the mixing plate 5, so the rubber scraper 13 will push the various materials on the mixing plate 5 to move together, thereby realizing the mixing activity. When the rubber scraper 13 rotates to the edge of the mixing plate 5, the fully mixed materials can fall through the mixing material outlet 12 for grinding.

[0038] Two blanking plates 8 are rotatably mounted inside the machine body 1 .

[0039] The fully mixed material falls on the discharge plate 8. By vibrating the discharge plate 8, the fully mixed material gradually falls down so that it can be evenly located on both sides of the grinding roller 9 for grinding.

[0040] One end of the rotating shaft 6 passes through the body 1 and is fixedly mounted with an incomplete gear 14. A rack 15 is slidably mounted on the back of the body 1. The rack 15 is adapted to the incomplete gear 14 and the two are in a meshing relationship.

[0041] When the rack 15 moves vertically, the incomplete gear 14 rotates, thereby driving the rotating shaft 6 to rotate.

[0042] By setting the number of teeth and the positions of the teeth, the incomplete gear 14 can only rotate 180°, so the mixed materials can fall alternately through the mixed material outlets 12 on both sides.

[0043] A telescopic rod 17 is installed on the back of the body 1, and a mounting plate 18 is fixedly installed on the output end of the telescopic rod 17. The mounting plate 18 is fixedly connected to the rack 15, and two driving devices 19 are fixedly installed on the mounting plate 18. The two driving devices 19 are located inside the body 1 and are adapted to the corresponding blanking plate 8.

[0044] Starting the telescopic rod 17 can move the mounting plate 18, and the movement of the mounting plate 18 causes the rack 15 and the two driving devices 19 to move synchronously.

[0045] The driving device 19 includes a fixed cylinder 23, a sliding rod 22 is slidably installed inside the fixed cylinder 23, a wheel body 20 is rotatably installed on the sliding rod 22, a spring 21 is fixedly installed on the fixed cylinder 23, and the other end of the spring 21 is fixedly installed on the wheel body 20, and the wheel body 20 can be in direct contact with the corresponding blanking plate 8.

[0046] When the driving device 19 moves, the wheel body 20 first contacts the bottom of the unloading plate 8, and then makes the unloading plate 8 rotate. Due to the limitation of the mixing plate 5, the unloading plate 8 cannot rotate. At this time, the wheel body 20 will gradually compress the spring 21, so that the sliding rod 22 is retracted into the fixed cylinder 23, and the driving device 19 smoothly moves from the bottom to the upper part of the unloading plate 8. After that, the unloading plate 8 will rotate without support, thereby realizing continuous vibration of the unloading plate 8, so that the unloading plate 8 can evenly place the mixed materials on both sides of the grinding roller 9.

[0047] Two limiting grooves 16 are provided inside the machine body 1 , and the connection between the blanking plate 8 and the machine body 1 is located inside the limiting grooves 16 . The blanking plate 8 is provided with gaps for materials to flow out at even intervals.

[0048] The rotation angle of the blanking plate 8 is limited by the limiting groove 16 .

[0049] The mixing plate 5 is semicircular in shape, and in the vertical projection, the feeding port 2 and the two mixed material outlets 12 on the mixing plate 5 have no overlapping parts.

[0050] Therefore, the materials entering through the feeding port 2 will only fall on the mixing plate 5 and can be discharged through the mixed material outlets 12 on both sides after being mixed.

[0051] Support rods 4 are evenly and equidistantly fixedly mounted on the bottom of the machine body 1 , and a damper 24 is arranged at one end of the support rods 4 facing away from the machine body 1 .

[0052] The existence of the damper 24 can effectively reduce vibration and ensure the stability of the overall operation of the equipment.

[0053] The working process of the utility model; different materials enter the body 1 through different feeding ports 2, and then fall on different positions of the mixing plate 5 respectively. Under the action of gravity, part of the materials gather to the center of the mixing plate 5 to achieve preliminary mixing.

[0054] By starting the telescopic rod 17, the mounting plate 18 can be moved, and the movement of the mounting plate 18 causes the rack 15 and the two driving devices 19 to move synchronously.

[0055] When the rack 15 moves vertically, the incomplete gear 14 will rotate, thereby driving the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 can drive the connecting plate 7 to rotate, and the rubber scraper 13 is in direct contact with the surface of the mixing plate 5, so the rubber scraper 13 will push the various materials on the mixing plate 5 to move together, thereby achieving mixing. When the rubber scraper 13 rotates to the edge of the mixing plate 5, the fully mixed materials can fall through the mixed material outlet 12 for grinding. By setting the number of teeth and the position of the teeth, the incomplete gear 14 can only rotate 180 degrees, so the mixed materials can be alternately dropped through the mixed material outlets 12 on both sides.

[0056] The mixed materials fall into the unloading plates 8 on both sides, and flow out through the gaps evenly and equidistantly provided on the unloading plates 8 for the materials to flow out.

[0057] The telescopic rod 17 makes the wheel body 20 first contact the bottom of the blanking plate 8, and then makes the blanking plate 8 rotate. When the blanking plate 8 cannot rotate, the driving device 19 smoothly moves from the bottom of the blanking plate 8 to the upper part. After that, the blanking plate 8 will rotate without support, thereby realizing continuous vibration of the blanking plate 8, so that the mixed material can be evenly placed on both sides of the grinding roller 9.

[0058] The motor 3 is started, and the cement grinding activity is realized by the rotation of the grinding roller 9. The particles with the desired size are filtered through the screen 10 and then discharged from the machine body 1 through the discharge port 11 and can be collected manually.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
