DETAILED DESCRIPTION OF THE EMBODIMENTS

The technical solution of the present invention is further explained below by accompanying drawings and the embodiments.

Referring toFIG.1toFIG.4, the present invention provides an adjustment-facilitating vibrating mill, including a base1, a grinding cylinder2, and a vibrating motor3, wherein an elastic mechanism4is arranged on the base1; the grinding cylinder2is fixedly connected to the elastic mechanism4; the vibrating motor3is arranged on the grinding cylinder2; two sides of the vibrating motor3are provided with eccentric mechanisms6; each eccentric mechanism6includes a fixed eccentric block61, an adjustment motor62, and an adjustable eccentric block63; the fixed eccentric block61sleeves an output shaft of the vibrating motor3; the adjustment motor62is connected to the fixed eccentric block61through a mounting seat15; and the adjustable eccentric block63is connected to the adjustment motor62through a transmission mechanism. In this embodiment, the transmission mechanism includes a transmission rod7and a transmission gear8; the transmission rod7is connected to the adjustment motor62through a coupler; the transmission gear8is engaged with the transmission rod7; a connecting shaft14is arranged on the adjustable eccentric block63in a penetrating manner; and the connecting shaft14is connected to an inner hole of the transmission gear8. During use, the adjustment motor62drives the transmission rod7to move, and the transmission rod7drives the transmission gear8engaged with the transmission rod to rotate. The transmission gear8thus drives the adjustable eccentric block63to move to finally adjust an included angle between the adjustable eccentric block63and the fixed eccentric block61. When the two eccentric blocks overlap, the exciting force is maximum. When the two eccentric blocks form a circle, the exciting force is minimum. The included angle between the adjustable eccentric block63and the fixed eccentric block61is adjusted using the adjustment motor62and the transmission mechanism, so that the exciting force can be adjusted without removing the vibrating motor and does not need to be adjusted manually by a user. The adjustment efficiency is improved. Effects of saving the labor and facilitating the adjustment and use are achieved. In this embodiment, a grinding medium made of a high-temperature-resistant material, i.e. zirconia, or a high-temperature-resistant anti-wear hard alloy material is arranged in the grinding cylinder2. The grinding medium may be spherical or rodlike.

Preferably, one side of the adjustable eccentric block63close to the transmission rod7is provided with a groove9, and the transmission gear8is located in the groove9. The groove9can protect the transmission gear8.

Preferably, a sliding chute10is formed inside the adjustable eccentric block63; one end of the sliding chute10close to a circle center of the adjustable eccentric block63is provided with a first spring11, and the other end of the first spring11is provided with a balance weight ball12. After the adjustment of the included angle between the adjustable eccentric block63and the fixed eccentric block61is completed, the adjustable eccentric block and the fixed eccentric block rotate with the output shaft of the vibrating motor. At this time, the balance weight ball12inside the adjustable eccentric block63will pull the first spring11to move outwards under the action of a centrifugal force, and the entire balance weight ball12skews to the outer side, which increases an eccentric force of the adjustable eccentric block63. When the rotating speed of the adjustable eccentric block63increases, the eccentric force greatly increases compared to that of an eccentric block without the balance weight ball12, so that an effect of adjusting the exciting force and the amplitude is achieved.

Preferably, a top of the grinding cylinder2is provided with a feed pipe21, and a bottom is provided with a discharge pipe22; a screen is arranged at an outlet of the discharge pipe22; an industrial camera is arranged on an inner wall of the discharge pipe22; a controller is arranged on the base1; and the industrial camera and the adjustment motor62are both electrically connected to the controller. The industrial camera is used for photographing powder particles on the screen.

During use, an appropriate screen can be selected according to a desired size of powder particles. Only powder particles smaller than a mesh can be discharged from the discharge pipe22, and powder particles larger than the mesh will remain on the screen. When there are many powder particles remaining on the screen, it indicates that the grinding effect at this time is poor, and the amplitude or exciting force needs to be changed. At this time, the industrial camera transmits what it photographs to the controller. The controller may control the adjustment motor62to be started to adjust the included angle between the adjustable eccentric block63and the fixed eccentric block61, thus completing the adjustment of the exciting force and the amplitude, and vice versa.

Preferably, the elastic mechanism4includes a rubber spring16, a lower supporting pillar17, and an upper supporting pillar; the lower supporting pillar17is fixedly arranged at a top of the base1; the upper supporting pillar is fixedly arranged on a connecting plate14on a side portion of the grinding cylinder2; and two ends of the rubber spring16respectively sleeve the lower supporting pillar and the upper supporting pillar. The upper supporting pillar and the lower supporting pillar are in one-to-one correspondence, and a bottom of the upper supporting pillar is provided with a round hole matched with the lower supporting pillar. In this embodiment, the lower supporting pillar and the upper supporting pillar can play a role of supporting and positioning when the grinding cylinder2is mounted on the base1, thus facilitating fast mounting. The rubber spring16is used as an elastic support between the grinding cylinder2and the base1, so that the structure is simple, and helps to enhance the vibrating effect on the grinding cylinder2and can also achieve a certain protection effect on the base. Furthermore, the controller on the base1can be protected from being affected by the vibration of the vibrating motor above, and the service life of the mill can be prolonged.

Preferably, a sound-proof housing is arranged on the base1; and the grinding cylinder2and the vibrating motor3are both located inside the sound-proof housing. The sound-proof housing can isolate sound and reduce noise.

Preferably, a protection cover5is arranged on an outer side of the eccentric mechanism6; and the protection cover is mounted on the vibrating motor3through a fixing screw. The protection cover5can protect the eccentric mechanism6, and can also avoid such a phenomenon that the adjustable eccentric block63and the fixed eccentric block61are thrown out and injure workers when they fail during working.

The above description is only preferred embodiments of the present invention, and is not intended to limit the technical scope of the present invention. As such, any minor amendments, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention shall fall within the scope of the technical solution of the present invention.
