Description

Gear set of multi-shaft sand mill and mounting method thereof

Technical Field

The invention relates to the technical field of sand mills, in particular to a gear set of a multi-shaft sand mill.

Background

At present, the sand mill is used for adding materials in a limited barrel space, and grinding the materials through a stirring rod and a steel ball, so that the volume of the materials in the barrel is further reduced until the materials in the barrel reach a target particle size.

Current sand mill is including the staving that is used for placing the material, the staving is close to the one end on ground and is located on the base, the one side that the staving was kept away from to the base sets up the rack that erects it, it is provided with three puddlers to rotate on the base, the staving cover is established in the puddler, the removable drive puddler pivoted grinder that is provided with of one side that the staving was kept away from to the base, it is more abundant to grind for the material in the staving, add appropriate amount steel ball in the staving, when operating personnel need grind the material, as long as pour the material of treating processing into the staving, then will start grinder, grinder drives the puddler and rotates, the puddler drives also can collide the material when driving the steel ball removal, thereby play the effect of grinding the material in the staving.

The above prior art solutions have the following drawbacks: the material in the grinding barrel is rotated in order to drive three puddler to current machine of grinding, provides three grinder in needs and drives three puddler rotations respectively, but three grinder has increased sand mill's whole volume, because the grinder of base is more, in case one of them breaks down, because the more volume of base grinder is great, can drive very big inconvenience for the maintenance of equipment on the contrary, and this problem is waited for and is solved urgently.

Disclosure of Invention

The invention aims to provide a gear set of a multi-shaft sand mill, which has the function of reducing the whole volume of the sand mill and facilitating the maintenance of an operator on a base.

In order to achieve the purpose, the invention provides the following technical scheme:

a gear set of a multi-shaft sand mill comprises a barrel body, wherein the barrel body is located on a base, a plurality of stirring rods are rotatably arranged on the base, a driving hole penetrates through the base and is arranged corresponding to the stirring rods, a driven driving shaft is rotatably arranged in the driving hole, and a connecting device for driving the stirring rods to rotate is arranged at one end, close to the stirring rods, of the driven driving shaft; a positioning device for fixing a plurality of driven driving shafts in opposite positions is arranged on one surface of the base, which is far away from the stirring rod; the fixed cover of one end that the puddler was kept away from to driven drive shaft is equipped with driven gear, the one side that the puddler was kept away from to the base is provided with and drives a plurality of driven gear pivoted drive arrangement, the removable setting of drive arrangement is on the base.

Through adopting above-mentioned technical scheme, on a plurality of driven drive gear passed through positioner relatively fixed diapire that sets up the base, the one end of keeping away from the puddler at the base passed through a drive arrangement, drives three driven gear and rotates, so drive arrangement quantity is only one, and to the base, holistic volume does not have too much the increase, and it is less to correspond the equipment under the maintainer base, and the volume is less also makes things convenient for dismouting and maintenance.
