Abstract

PURPOSE:To scrape matters attached on the bottom surface of a sectional chamber smoothly after dropping and discharging material by rotatably supporting a scraper on a shaft at a proper position inside a discharge port of a rotary chamber to freely oscillate up and down in response to the transfer of the sectional chambers by rotation of a rotor. CONSTITUTION:Sectional chambers 6 of a rotor 5 installed on a shaft in a rotor chamber 1 are formed to have smooth bottom surfaces 7, and a scraper 8 formed at a scraping part 9 in pressure contact with the surface of the sectional chamber with the forward end part directed upward separately in a discharge port 4 connected to the rotor chamber 1 is rotatably supported on a shaft at a proper position. This scraper 8 is oscillated up and down through a cam 14 and a roller in response to the transfer of the sectional chambers 6 by rotation of this rotor 5, so that sticking/attaching matters of subject material in the sectional chambers 6 of the rotor 5 are removed by this scraper 8. In addition, the roller is pushed up against a spring 10 by the cam 14 in response to clockwise rotation of the rotor 5, so that the scraping part 9 moves down without prohibiting pass of the sectional chambers 6.

In the present invention, a scraper formed in a scraping portion that presses against the compartment surface with its tip facing upward is pivotally supported in a proper position within the discharge port. For example, the scraper is pivotally supported at appropriate locations near both ends of the scraper along the rotor shaft and on the inner surface of the discharge port. At this time, the pressure contact of the scraper is performed using, for example, a spring or a weight. The scraper preferably has a tip portion formed by bending a wire rod into a U-shape and forming a scraping portion with the middle portion facing upward. In this case, the wire rod is preferably in the shape of a round rod.

The operating mechanism of the scraper is not sufficiently effective if the scraper is simply in contact with the compartment surface of the rotor; however, if the contact force is increased, it becomes difficult for the scraper to escape from the compartment after scraping. Therefore, it is preferable that the scraper is set to move in synchronization with the rotor so that the scraper can have a sufficient pressure contact force and can be smoothly removed. Such an operating mechanism may be any commonly used synchronous interlocking mechanism, and among these, a cam mechanism is preferred.

Also, the depth (d) of the compartments of the rotor is determined by the pitch (i2)
If the layer is made shallower, the layer scraper can be made smoother by configuring the scraper to swing up and down in front of the vertical centerline of the rotor when viewed in the direction of rotation of the rotor as the compartments transition due to the rotation of the rotor. Therefore, there is no need to separately provide a precise synchronization interlocking mechanism such as a cam mechanism.

Next, on the inner surface of the discharge port 4 of the rotor chamber l, there is a scraper 8 formed by bending a round bar-shaped metal wire into a U-shape, and further bending it into an L-shape when viewed from the side. A cam mechanism ll is attached to the rotor chamber 1, and is supported by a shaft as a scraping portion in contact with the inner surface of the compartment, and is held so as to constantly rise via a spring IO.
It is designed to descend each time in synchronization with the rotational transition of each compartment of the rotor. That is, as is clear from FIG. 2, this scraper is pivotally supported on a shaft 12, and the scraping portion at the tip is always pressed into the compartment via a spring 10, and the roller 1 provided at the other end
3 is brought into contact with a cam 14 which is axially installed at a proper position, and this cam 14 and rotor are synchronously rotated via chain wheels 15 and 16. As a result, when the rotor rotates clockwise as shown by the chain line in FIG. 3 and approaches the state shown by the solid line in the figure, at the same time the roller 13 is pushed up by the cam 14 against the spring IO, and the scraping section is It is lowered so that there is no hindrance to passage through the compartment. Note that the pressure contact may be performed using a weight instead of a spring.

Effects of the Invention As described above, the present invention has the remarkable effect that deposits on the bottom of the compartment are smoothly scraped off by the scraping portion raised by the spring IO or the like after the material has been dropped and discharged.

Furthermore, when a synchronous interlocking mechanism such as a cam mechanism is attached, the tip of the scraping part is forcibly lowered via the synchronous interlocking mechanism such as the cam mechanism 11 just before the next compartment arrives, and in this way, There are many advantages such as there is no risk of getting caught in the moving compartment, each compartment can be sufficiently deep, and the capacity of the rotary feeder will not be reduced even if a scraping section is provided. Furthermore, since the scraping section is made of wire rods, there is no risk of damming up material falling from the compartment, making it extremely efficient.
