Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic structural view of the present invention (excluding the storage vat);
fig. 2 is a sectional view a-a of fig. 1.
The reference numbers in the figures are as follows: 1. a hoisting ring; 2. a boom; 3. a conical baffle; 4. a barrel cover; 5. a storage barrel; 6. a cross support bar; 7. a base plate; 8. and (3) supporting the ring.
Detailed Description
The utility model provides a storage and replenishing device of ball mill steel ball can repeatedly use again on the basis of the assurance operator safety, reduce cost consumption.
Referring to fig. 1 and 2, the utility model mainly comprises a hanging ring 1, a hanging rod 2, a conical baffle 3, a barrel cover 4, a storage barrel 5, a cross-shaped support rod 6, a base plate 7 and a support ring 8.
The hanger rod 2 is connected with the hanging ring 1 and the conical baffle 3 and can move up and down;
the conical baffle 3 is not connected with the bottom plate of the storage barrel 5, and the projection area of the conical baffle 3 on the horizontal plane is slightly larger than the area of the discharge hole at the bottom of the storage barrel 5, so that when the storage barrel 5 is lifted, the conical baffle 3 can clamp and seal the discharge hole of the storage barrel 5;
