Sand blasting machine adding steel sand auxiliary dumping equipment

The invention relates to an auxiliary material dumping device applied to a sandblasting machine for adding steel sand.

When the existing sand blasting machine is in operation, it must be pre-filled with steel grit in each of its steel sand funnel tanks to provide the materials required for sandblasting operations. In general, there are two types of steel sand addition operations, of which:

The first type of steel sand addition operation is to adopt a bagged steel sand adding method, in which the capacity of each bag is about 45 kg, and the bag is manually removed, and the bagged steel sand is poured into the steel sand funnel. The capacity of the existing sand blasting machine grit funnel tank is about 1500 kg, and the capacity of the bagged steel grit is small, that is, it is necessary to manually operate the steel sand funnel tank for dozens of times. Therefore, the manual operation method adds the steel sand method, which is time consuming. The problem of labor.

The second steel sand addition operation is to adopt a barrel-added steel sand adding method, in which the capacity per barrel is about 750 kg. Because of the weight of the barrel steel grit, it is necessary to lift the steel grit barrel by the crane and directly remove the barrel cover. It is dumped in the steel sand funnel tank of the steel sand machine. Although this method can be combined with the lifting design lifting, it is labor-saving and simpler than the manual operation of the bagged steel grit. However, in actual operation mode, The following issues have yet to be overcome, including:

1. When the steel grit added is lifted, the steel cable ring shall be placed on a steel sand drum with a weight of 750 kg. After the steel drum is lifted, the steel sand drum may be slipped due to rotation and cable slip. The danger of steel sand falling over.

2. When the crane lifts the steel grit barrel to the sandblasting work car above the sand blasting machine, the hook of the crane is easy to collide with the sandblasting chamber wall of the sand blasting machine, and the steel sand barrel is placed in the sand blasting work vehicle when the material is to be poured, the steel The location of the sand bucket and the operator is not safe and is dangerous.

3. When the crane is dumped, it is impossible to pour all the steel sand in the steel drum into the steel sand funnel. It still needs to be sent by the human hand shovel to send the steel sand into the steel sand funnel. There are disadvantages of time and labor.
