Description

[Detailed Description of the Invention] The present invention relates to a vibrating hopper equipped with an unbalanced weight attached to a hopper vibrating section and a motor for rotating the unbalanced weight.

Conventionally, in the above-mentioned vibrating hopper, both the unbalanced weight 13 and the motor 7 were attached to the hopper vibrating part 1b as shown in FIG. It has to be heavy, which increases the equipment cost.The load on the mounting part A of the motor 7 and the unbalanced weight 13 is large, which tends to cause problems such as cracking, and energy is wasted to vibrate the motor 7. There were various drawbacks such as:

An object of the present invention is to provide a vibrating hopper that is superior in equipment cost, operating cost, and durability by improving the hopper vibrating configuration.

The characteristic structure of the vibrating hopper according to the present invention is that the motor for rotating the unbalanced weight attached to the hopper vibrating part is attached to the fixed part and operatively connected to the unbalanced weight via a flexible supring. be.

The effects of the characteristic configuration of the present invention are as follows. In other words, the motor is mounted on a fixed part to prevent it from vibrating, and the action of the flexible coupling suppresses the propagation of vibration from the unbalanced weight to the motor. can be used, greatly reducing equipment costs required for motors,
In addition, the load on the vibration component attachment part to the hopper vibration part can be made smaller than before by approximately the amount due to the weight of the motor, making the attachment part lighter and smaller and making it easier to prevent cracks from occurring in the attachment part. Furthermore, the energy required for hopper vibration can be reduced by approximately the amount required for motor vibration compared to the conventional method, and as a result, a vibrating hopper with low initial cost and running cost and excellent durability can be provided. Ta.

Next, an embodiment will be described with reference to FIGS. 1 and 2.

The hopper upper part 1a is fixed to a plurality of fixed upright columns 2, and the hopper vibrating part 1b, which is equipped with an opening/closing lid 3 and a discharge port 4, is attached to the lower end of the hopper upper part 1a. Via the connector 5,
The hopper upper part 1a and the hopper vibrating part 1b are connected to each other in a suspended manner, and the space between the hopper upper part 1a and the hopper vibrating part 1b is sealed with a flexible member 6. The hopper vibrating section 1b is forcibly vibrated by the vibrators 7 and 8 so that the contents inside the hopper can be smoothly and reliably taken out from the discharge port 4.

The mounting base 9 of the motor 7 is bolted to a bracket 10 attached to the hopper upper part 1a, and the bearing member 11 of the gyrator 8 is attached to the hopper vibrating part 1.
The motor 7 is connected via a flexible coupling 15 to a rotating shaft 14 which is bolted to a bracket 12 attached to b and is attached to a bearing member 11 and has four unbalanced weights 13a, 13b, 13c, and 13d. are connected so that an excitation force is generated as the unbalanced weights 13a to 13d are rotated by the motor 7.
Moreover, it is configured to suppress vibrations of the motor 7.

Unbalanced weight 13 relative to rotating shaft 14
The relative fixed phase of a to 13d is configured to be performed by operating the bolt 16, so that the magnitude and direction of the excitation force can be adjusted. The flexible coupling 1 can be removably attached to the member 11 and can be attached without removing the main parts of the motor 7 and the gear generator 8.
5 and the upper cover 17a can be removed, so that the excitation force can be easily adjusted.

Next, another example will be shown.

The motor 7 may be attached to the support column 2 or a member connected thereto.
It is sufficient if the motor 7 is attached to a and 2.

The specific structure of the gyrator 8 can be freely changed, and a plurality of gyrators 8 may be arranged around the hopper symmetrically with respect to the center of gravity of the vibrating object. It is only necessary to provide one unbalanced weight 13 for both.

The specific configurations of the flexible coupling 15 and the hopper can also be changed, and the objects to be stored in the hopper are various powders and lumps.
