Large-range bulk hopper

Technical Field

The utility model relates to a field of weighing specifically relates to a wide range bulk material fill.

Background

The sensor is one of the important components of a weighing sensor, by which the weight of the material in the hopper can be measured quickly. The common sensor for mounting the hopper is traditionally that the hopper is hoisted, a bearing block (namely a false sensor) is placed at the mounting position of the hopper, then the hopper is put down, then the hopper is jacked up by a jack at each bearing point to take out the bearing block, and finally the sensor is put in.

However, the bulk hopper cannot be applied to the above method because the bulk hopper has a weight and a shape much larger than that of a general hopper, and if the bulk hopper sensor is installed in a general manner, there are the following problems:

1. no suitable crane or lifting point can be found.

2. The bearing block has very large volume and mass, and is difficult to carry and place.

3. The dead weight of the large-range bulk hopper is generally 40-50t, and the situation that the body is unstable after too many supporting points are reduced when the large-range bulk hopper is modified must be considered.

4. The upper and lower mounting surfaces of a common hopper sensor are subjected to plane processing to meet the mounting requirements of the sensor, and the upper and lower mounting plates of the bulk hopper sensor are required to be subjected to the procedures of hole cutting, welding, reinforcement and the like to complete the parallelism between the upper and lower parts, so the parallelism is difficult to guarantee.

5. The upper and lower mounting surfaces of the bulk hopper are difficult to locate.

The invention has the advantages of novel structure and accurate weighing. But the scheme is not suitable for the installation requirement of the sensor supporting seat of the large-scale bulk material hopper.
