Description

Technical Field

[0001] The utility model belongs to the technical field of vibration devices, and in particular relates to a vibration device for a cement grinding lower bin. Background Art

[0002] Cement grinding equipment is used to process cement raw materials. After grinding the cement raw materials, the cement grinding equipment will discharge them through the hopper. However, during discharge, part of the cement will stick to the inner wall of the hopper, which will cause the hopper to be easily blocked. Therefore, in order to prevent the cement from sticking to the inner wall of the hopper, the hopper needs to be vibrated. Common vibrations are performed manually, which is labor-intensive. There are also internal vibration mechanisms that can shake off the cement stuck on the inner wall. However, in actual use, since the cement is in powder form, part of the cement may float and fall on the working end of the internal vibration mechanism, which will cause the cement in the hopper to remain. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a vibration device for the lower silo of a cement grinding mill.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A vibrating device for a cement grinding lower bin comprises a lower bin installed at the output end of a grinding mill, the bottom of the lower bin is in an inverted cone shape, the lower bin is connected to a discharge port, and a vibrating mechanism is installed on the side of the lower bin;

[0006] The rapping mechanism comprises a base, the base is equipped with a rotating shaft platform, the rotating shaft platform is rotatably equipped with a first reciprocating screw rod and a second reciprocating screw rod, and the diameter size and pitch of the first reciprocating screw rod and the second reciprocating screw rod are different;

[0007] The first reciprocating screw rod is threadably matched with a sleeve, a first plate and a second plate are hingedly mounted on the outer side of the sleeve, the first plate and the second plate are hinged to each other, the sleeve serves as a hinge axis of the first plate and the second plate, the first plate and the second plate are both connected with a contact block, a spring is fixedly connected between the two contact blocks, and the two contact blocks are both provided with an inclined surface;

[0008] The second reciprocating screw thread is matched with a contact sleeve, and the contact sleeve is cylindrical;

[0009] The other ends of the first reciprocating screw rod and the second reciprocating screw rod are installed with a gear box, a guide rod is connected between the gear box and the rotating shaft platform, the contact sleeve is arranged on the outside of the guide rod, the gear box is installed with a motor, the output end of the motor is connected with a driving gear, and the ends of the first reciprocating screw rod and the second reciprocating screw rod are both installed with a driven gear that meshes with the driving gear.

[0010] It is further defined that height-adjustable support feet are installed at the bottom of the base, and such a design can adapt to the use of lower silos of different heights.

[0011] It is further defined that the gear box is fixedly mounted on the top of the lower silo. Such a design ensures the overall supporting strength.

[0012] It is further defined that the first hitting plate and the second hitting plate are both installed with a plurality of touch balls, and such a design enhances the contact rapping effect.

[0013] It is further defined that the contact block is detachably mounted on the corresponding first hitting plate and the second hitting plate. Such a design facilitates replacement of the contact block to ensure the use effect.

[0014] The beneficial effects of adopting the utility model are:

[0015] With the structural design of the utility model, the operation of the motor can drive the sleeve to move up and down and reciprocate, thereby realizing the reciprocating movement of the first hitting plate and the second hitting plate. At the same time, the operation of the motor drives the lifting and moving of the contact cylinder. When the contact cylinder contacts the contact block, the lower bin is vibrated. Because the pitches of the first reciprocating screw rod and the second reciprocating screw rod are different, the positions of the contact cylinder and the contact block when they contact will become random, thereby realizing the comprehensive vibration of the lower bin, ensuring that the cement adhering to the inner wall of the lower bin is shaken off.

[0016] With the structural design of the utility model, since the vibration is performed on the outside, cement will not fall on the working end of the internal vibration mechanism, thereby causing the problem of cement residue to occur. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 to Figure 5 As shown, the utility model is a vibrating device for a cement grinding lower bin, comprising a lower bin 1 installed at the output end of the grinding mill, the bottom of the lower bin 1 is in an inverted cone shape, the lower bin 1 is connected to a discharge port 2, and a vibrating mechanism 3 is installed on the side of the lower bin 1;

[0028] The rapping mechanism 3 includes a base 31, on which a rotating shaft 32 is mounted, on which a first reciprocating screw 33 and a second reciprocating screw 34 are rotatably mounted, and the first reciprocating screw 33 and the second reciprocating screw 34 have different diameters and pitches;

[0029] The first reciprocating screw rod 33 is threadedly matched with a sleeve 35, and a first plate 36 and a second plate 37 are hingedly installed on the outer side of the sleeve 35. The first plate 36 and the second plate 37 are hinged to each other, and the sleeve 35 serves as a hinge axis of the first plate 36 and the second plate 37. The first plate 36 and the second plate 37 are both connected with a contact block 38, and a spring 39 is fixedly connected between the two contact blocks 38. The two contact blocks 38 are both provided with an inclined surface 310;

[0030] The second reciprocating screw rod 34 is threadably matched with a contact cylinder 311, and the contact cylinder 311 is cylindrical;

[0031] A gear box 312 is installed at the other end of the first reciprocating screw rod 33 and the second reciprocating screw rod 34. A guide rod 313 is connected between the gear box 312 and the rotating shaft platform 32. The contact cylinder 311 is sleeved on the outside of the guide rod 313. The gear box 312 is installed with a motor 314. The output end of the motor 314 is connected to a driving gear 315. The ends of the first reciprocating screw rod 33 and the second reciprocating screw rod 34 are both installed with a driven gear 316 that meshes with the driving gear 315.

[0032] In this implementation case, when a rapping device for a cement grinding lower bin is used, the material output by the grinding mill enters the lower bin 1 and is discharged from the discharge port 2;

[0033] When the material is in the lower bin 1, the motor 314 drives the driving gear 315 to rotate, and then drives the driven gears 316 meshing on both sides to rotate, and the first reciprocating screw 33 and the second reciprocating screw 34 rotate accordingly;

[0034] Due to the rotation of the first reciprocating screw 33 and the limitation of the first hitting plate 36 and the second hitting plate 37, the sleeve 35 reciprocates up and down on the first reciprocating screw 33, and also drives the first hitting plate 36 and the second hitting plate 37 to move up and down;

[0035] Under the rotation of the second reciprocating screw 34 and the limitation of the guide rod 313, the contact cylinder 311 performs up and down reciprocating motion on the second reciprocating screw 34;

[0036] When the up and down reciprocating motion of the contact cylinder 311 contacts the contact block 38, under the traction of the inclined plane 310, the first beating plate 36 and the second beating plate 37 move relative to each other with the sleeve 35 as the axis, and then hit the lower material bin 1 to achieve the purpose of vibration. When the contact cylinder 311 leaves the contact block 38, under the effect of the spring 39, the first beating plate 36 and the second beating plate 37 return to their original positions until the next contact between the contact cylinder 311 and the contact block 38. Because the pitches of the first reciprocating rod 33 and the second reciprocating screw rod 34 are different, the height position of the contact cylinder 311 when it contacts the contact block 38 is uncertain, thereby achieving vibration of different positions of the lower material bin 1, ensuring the vibration area, and then ensuring the vibration effect.

[0037] Preferably, a height-adjustable support foot 317 is installed at the bottom of the base 31. Such a design can adapt to the use of lower silos 1 of different heights. In fact, the structure of the support foot 317 can also be considered according to specific circumstances.

[0038] Preferably, the gear box 312 is fixedly installed on the top of the lower silo 1. Such a design ensures the overall supporting strength. In fact, the fixing method of the gear box 312 can also be considered according to specific circumstances.

[0039] Preferably, the first beating plate 36 and the second beating plate 37 are both installed with a plurality of contact balls 318. Such a design enhances the contact rapping effect. In fact, the structure of the contact rapping may also be considered according to specific circumstances.

[0040] Preferably, the contact block 38 is detachably mounted on the corresponding first plate 36 and second plate 37. Such a design facilitates replacement of the contact block 39 to ensure the use effect. In fact, the installation method of the contact block 38 can also be considered according to specific circumstances.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
