Description

[Detailed description of the invention] (Industrial application field) This invention is a method of discharging a mixture of granules, powder, etc. mixed in a mixing tank of a mixing machine by dropping it from an opening at the bottom of the mixing tank. It is related to the device.

(Prior art) As described in Japanese Utility Model Publication No. 48-6992, this type of conventional discharge method uses an opening/closing plate provided at the bottom opening of a storage chamber for grains, etc. in the longitudinal direction of the storage chamber. It is rotated in a right angle direction and lowered to open and take out grains, etc. from the storage chamber.

(Problems to be solved by the invention) In the conventional discharge method described above, since the bottom opening of the storage chamber is long, the grains, etc. that fall from the bottom opening are collected in one place by flowing down onto the discharge gutter. To remove it, a long drain gutter is required, which has a triangular shape when viewed from above.

Therefore, there is a problem in that the height of the machine increases accordingly in order to install the discharge gutter.

(Means for Solving the Problems) Therefore, in order to solve the above problems, this invention has been devised so that the entire length of the mixing tank 3 is fixed at the bottom of the mixing tank 3 containing a rotary agitator 2 which is constructed by a rotating shaft 1 in the front and back direction. An opening 4 is provided across the area, and a discharge gutter 5 that slopes forward is provided below the opening 4. Behind the opening 4, the base of the opening/closing plate 6 of the opening 4 is pivoted by a horizontal shaft 7, and in front of the A stopper 8 of the opening/closing plate 6 is pivotably supported so as to be rotatable back and forth, and pressed rearward by a spring 9, and a push-up arm 10 is pivotally supported below the opening/closing plate 6 so as to be movable up and down. The stopper 8, the push-up arm 10, and their operation parts are operated so that only the stopper 8 rotates forward, and the stopper 8 rotates forward as the push-up arm 10 rises. They are connected by the interlocking mechanism a obtained.

(Function) When the stopper 8 is rotated forward by the operation part, the stopper 8 is removed from the opening/closing plate 6, so that the opening/closing plate 6 is moved by its own weight and the weight of particles in the tank 3. It rotates downward and opens using the horizontal shaft 7 as a fulcrum.

On the other hand, when the push-up arm 10 is raised by the operating section, the opening/closing plate 6 is pushed up by the push-up arm 10 and rotates upward about the horizontal shaft 7, and at the same time, the stopper 8
rotates forward. Therefore, the opening/closing plate 6 is connected to the tank 3.
When the opening/closing plate 6 is closed by contacting the bottom surface of the opening/closing plate 6, the tip of the opening/closing plate 6 is caught on the stopper 8, and the opening/closing plate 6 is fixed in the closed state.
