Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings 1-2.

With reference to fig. 1 and 2, the grinding barrel of the present embodiment includes a grinding barrel body 1 and a rotating shaft 2, the rotating shaft 2 can rotate relative to the grinding barrel body 1, the rotating shaft 2 penetrates through the axis of the grinding barrel body 1, the rotating shaft 2 is fixedly connected with an eccentric weight 3, the rotating shaft 2 drives the eccentric weight 3 to synchronously rotate when rotating, an eccentric acting force generated when the eccentric weight 3 rotates drives the rotating shaft 2 and the grinding barrel body 1 to generate eccentric vibration, and a plurality of grinding rods capable of moving relative to each other are arranged in the grinding barrel body 1; this grinding barrel is when being used for grinding, the eccentric vibrations of grinding barrel body 1 make the violent motion of material and grinding rod in the grinding barrel body 1, thereby realize the grinding to the material, the eccentric force that grinding barrel body 1 received is produced by the rotation of eccentric balancing weight 3, the size of eccentric force has the inseparable relation with the rotational speed of eccentric balancing weight 3 and other factors, this size that leads to the eccentric force is changing constantly, consequently, the vibrations direction of grinding barrel body 1 also is not regular, the above-mentioned mode makes the motion of material and grinding rod in grinding barrel body 1 more violent, thereby guaranteed the grinding effect to the material, the granule size after the grinding is comparatively even.

As the utility model discloses the alternative, eccentric balancing weight 3 respectively is provided with one in 2 both sides of pivot, eccentric balancing weight 3 is located outside the grinding staving 1, the both ends of grinding staving 1 are located respectively to two eccentric balancing weights 3, rotate the eccentric balancing weight 3 that drives both sides together and rotate in pivot 2, two eccentric balancing weights 3 produce the same eccentric power in order to order about 2 synchronous motions in both ends of pivot, thereby both ends keep same frequency when guaranteeing to grind 1 vibrations of staving, if only set up an eccentric balancing weight 3, then need install this eccentric balancing weight 3 in the axle center department of grinding staving 1, whether incline to grind 1 one side atress of staving and can lead to grinding 1 upset of staving and cause the incident when receiving great eccentric power.

As an alternative of the present invention, a protection ring 4 is arranged outside the grinding barrel 1, the eccentric weight 3 rotates in the protection ring 4, and the protection ring 4 is a circular ring-shaped protrusion integrally formed at the end of the grinding barrel 1; the guard ring 4 can play better guard action when eccentric balancing weight 3 is rotatory, avoids eccentric balancing weight 3 rotatory in the environment that exposes to cause danger.

As the utility model discloses the alternative, first water-cooling jacket 5 has been linked firmly through the screw in the grinding barrel body 1, outside pivot 2 was located to 5 covers of first water-cooling jacket, because can take place the friction with grinding barrel body 1 when pivot 2 is rotatory and produce a large amount of heats, if not in time with this part heat dissipation then can make the material in the grinding barrel body 1 be in high temperature environment, in this embodiment, pivot 2 is at 5 internal rotations of first water-cooling jacket, the heat that the friction produced in time dispels the heat through first water-cooling jacket 5, the lateral wall of first water-cooling jacket 5 contacts with the material to can prevent that high temperature from influencing the grinding effect.

As the utility model discloses the alternative, grinding 1 outer second water-cooling jacket 6 has been linked firmly, 6 covers of second water-cooling jacket are located outside grinding 1 staving, the inner wall of second water-cooling jacket 6 is laminated mutually with grinding 1 outer wall of staving, and second water-cooling jacket 6 can in time dispel the heat to the heat on grinding 1 staving (the heat that produces when grinding the material can transmit to grinding 1 on the staving), and first water-

cooling jacket

5 and 6 cooperations of second water-cooling jacket make grinding 1 staving keep lower temperature when grinding the material, avoid the high temperature material of burning.

As the utility model discloses the alternative, the both ends of grinding staving 1 are connected with bearing fixing cover 7 respectively, install bearing 8 in the bearing fixing cover 7, on bearing 8 of both sides was worn to locate respectively at the both ends of pivot 2, in this embodiment, for bearing 8's change and additional lubrication oil, bearing fixing cover 7 can dismantle through the screw and connect on grinding staving 1.
