AI Technical Summary
There are no small stoves that can stably burn rice husks or buckwheat husks and convert them into stable charcoal while allowing for continuous operation.
A small stove design that supplies air to rice husks moving inside a cylindrical combustion frame, enabling stable combustion and continuous operation by using a spring-type conveyor to move the husks and a blower to mix air with the combustible gas.
Rice husks can be used as fuel, producing stable charcoal that serves as agricultural fertilizer and mulching material, facilitating continuous production and discharge.

Abstract
Description
[Technical Field]
[0001] This small stove supplies air to rice husks (buckwheat husks), which are difficult to burn stably on their own, and burns them while moving, achieving stable combustion. [Background technology] Large rice husk stoves that also serve as charcoal makers exist, but there are no small stoves with the same functions. Summary of the Invention [Problem to be solved by the invention]
[0002] Nowadays, rice husks (buckwheat husks), which are usually treated as waste, can be easily used as fuel.
[0003] After burning, the rice husks become "smoked charcoal" and can be used as agricultural fertilizer, soil conditioner, and mulching material. [Means for solving the problem]
[0004] By blowing air into the rice husks (buckwheat husks) moving inside a cylindrical combustion frame, stable combustion is possible even with small amounts.
[0005] The supply, combustion, and discharge of rice husks (buckwheat husks) can be carried out in a single operation. [Effects of the Invention]
[0006] Currently, rice husks (buckwheat husks), which are treated as waste, can be used as fuel.
[0007] After burning, the rice husks can be used as "smoked charcoal" and as agricultural fertilizer, soil conditioner, and mulching material. [Brief explanation of the drawings]
[0008] [Figure 1] FIG. [Figure 2] FIG. [Figure 3] FIG. Mode for carrying out the invention
[0009] Rice husks (buckwheat husks) are placed in a hopper and enter a cylindrical combustion frame. As they are moved to the combustion chamber by a spring-type conveyor, air coming out of the nozzle at the bottom of the frame is mixed with the combustible gas generated by heating, resulting in stable combustion.
[0010] After combustion, the charcoal is pushed out at the same time as it is fed, falls into a charcoal basin, and is then discharged by a conveyor. [Explanation of symbols]

Claims
1. This small stove uses a cylindrical combustion frame to transport rice husks (buckwheat husks), which are difficult to burn as they are, and supplies air directly into the frame, resulting in stable combustion.
2. Smoked charcoal can be produced using a simple device that can simultaneously supply and discharge rice husks (buckwheat husks) to the combustion section.
