Description

[Detailed description of the device]

[0001]

[Industrial field of application]
The present invention relates to a hopper that has a powder / granule feeder that is housed inside a container or the like and cuts out and discharges the powder / granular material.

[0002]

2. Description of the Related Art A motor-driven rotary supply board is provided in the lower peripheral portion of a hopper, and the rotary supply board stores a fixed amount of powder and granules, transfers the powder and granules to the outside of the hopper, and discharges them outside the hopper. Are known.

[0003]

In the conventional powder and granular material feeder, since the powder is discharged from the outer peripheral portion of the lower part of the hopper, it is difficult to supply a required amount of the powder or granular material to the container or the like just below the hopper. Further, there is also a demand for smoothly discharging the powder and granules from directly under the hopper, and further for facilitating the repair and maintenance of the drive unit such as the motor, and a powder and granule feeder satisfying these requirements has been desired.

An object of the present invention is to supply a practical granular hopper which can smoothly supply the granular material from directly below the hopper and is easy to repair and maintain.

[0005]

Means for Solving the Problems The gist of the present invention which has solved the above problems is to provide a cylindrical portion in a reduced diameter lower portion of a hopper containing powder and granules, and to install a rotary table with a cone at a position above the cylindrical portion. In addition to providing the rotary table, an opening for powder particles is opened on the peripheral side upper surface of the rotary table, and an annular partition wall extending to the bottom wall of the cylindrical portion is provided on the rear surface of the rotary table. An annular box space is formed by and a scraper inserted into the annular box space is projected from the annular partition wall, and the advancing side annular partition wall part of the rotary table is opened near the scraper to serve as a powder and granule scraping outlet, and the rotary table It is a powdery hopper provided with a motor for driving a rotary table below the center and a casing for protecting the motor.

[0006]

In this invention, the powder and granules in the hopper are slightly moved by the rotation of the rotary table and the cone, and are dropped from the powder and granule drop opening of the rotary table into the annular space below and rotate together with the rotary table. The scraper is scraped out from the powder or granular material discharge port.

Since the powdery or granular material discharge port is rotated, the powdery or granular material to be scraped out is uniformly discharged from just below the hopper. Further, since the powdery particles are discharged directly below the hopper without moving largely, the powdery particles can be supplied smoothly, and the horsepower of the drive motor can be small.

Further, since the drive motor is mounted below the rotary table, repair / maintenance is easy.

Embodiments of the present invention will be described below with reference to the drawings.

First Embodiment (See FIGS. 1 to 3) The first embodiment shown in FIGS. 1 to 3 is applied to a hopper installed on a traveling vehicle (not shown). An opening serving as a powdery or granular material discharge port 4 is provided at the center of the bottom wall 3 of the cylindrical portion 2 below the hopper 1, and an annular partition wall 6 provided on the back surface of the rotary table 5.
Is an example provided inside. In the figure, 7 is an annular space, 8 is a powdery or granular material drop port of the rotary table 5, 9 is a scraper, and 10 is a scraper.
Is an outlet for the granular material of the annular partition wall 6, 11 is a cone standing upright in the center of the rotary table 5, 12 is a motor casing mounted below the rotary table 5, and 13 is the same motor casing 1.
It is a motor built in 2 and removes the rotation table 5. Reference numeral 14 is a support stage for the motor casing 12, and 15 is a shoe.

In this embodiment, the powder and granules in the hopper 1 are guided by the motor casing 12 and are all introduced into the cylindrical portion 2 and fall from the powder and granule drop opening 8 into the annular box space 7 to scrape the powder and granules. 1 through the outlet 10 and the powder / particle discharge port 4
5 is discharged.

Second Embodiment (Refer to FIGS. 4 and 5) In the second embodiment shown in FIGS. 4 and 5, the annular partition wall 6 of the rotary table 5 and the powder and granular material scraping outlet 10 are on the outer side and the inner side thereof. The annular box space 7 is formed by the fixed vertical wall 16 on the hopper side, and the powder particles in the ring box space 7 are discharged to the outside by the scraper 9. Others are the same as those in the first embodiment.

[0013]

As described above, according to the present invention, the granular material in the hopper is slightly moved by the rotation of the rotary table and the cone to the extent that bridges and cavities are not generated, and falls into the lower masu space. Since the scraper discharges the powder or granules from the dropping place, it is not necessary to move the powder or granules largely, and the powder or granules can be discharged smoothly. Moreover, the powder can be discharged directly below the hopper, and the powder and granules can be easily transferred. Further, the motor may have a small horsepower and the motor is located under the rotary table, so that the repair / maintenance is easy.
