A grate 11 is laid on the square, and the grate 11 is placed above the slag discharge door 5. A support rod 7 is vertically fixed to the side of the upper surface of the workbench 1 away from the furnace body 2, and a fixed cylinder 8 is horizontally arranged on the side of the furnace body 2 close to the support rod 7. The top of the support rod 7 supports the end of the fixed cylinder 8 to adjust the stability of the fixed cylinder 8. The fixed cylinder 8 is connected to the inside of the workbench 1, and a docking hole 9 is opened above the end of the fixed cylinder 8 away from the furnace body 2. The top of the docking hole 9 is connected to a hopper 10, and the hopper 10 and the docking hole 9 can be disassembled.

[0026] Please refer to Figure 1-Figure 3As shown, a movable cylinder 13 is slidably penetrated through the inner side of the fixed cylinder 8, and the movable cylinder 13 can slide along the axis of the fixed cylinder 8. A screw conveying shaft 16 is rotatably installed inside the movable cylinder 13, and a rotating handle 17 is provided at the end of the screw conveying shaft 16. The rotating handle 17 is placed on the outer side of the movable cylinder 13, so that the screw conveying shaft 16 can be driven to rotate by the external rotating handle 17, so as to transport the granular materials that fall into the movable cylinder 13 to the rear. A feed hole 14 is provided on the upper surface of the movable cylinder 13 at one end close to the rotating handle 17, and the feed hole 14 corresponds to the position of the docking hole 9. When filling, the movable cylinder 13 is pushed inward. When the discharge hole 15 is placed at the center of the furnace body 2, the feed hole 14 coincides with the docking hole 9, so that the granular materials inside the hopper 10 can fall into the movable cylinder 13.

[0027] Among them, a discharge hole 15 is opened at one end of the lower surface of the movable cylinder 13 away from the rotating handle 17, and the discharge hole 15 is placed inside the furnace body 2, and the discharge hole 15 is downward to realize the feeding work. A limiting platform 12 is provided on the side of the back of the furnace body 2 close to the fixed cylinder 8, and the limiting platform 12 is placed below the movable cylinder 13. The position of the limiting platform 12 corresponds to the discharge hole 15. When the feeding is completed, the movable cylinder 13 is pulled outward to make the feed hole 14 and the docking hole 9 misaligned, the feeding is stopped, and the bottom of the discharge hole 15 is open and sealed by the limiting platform 12 to prevent obstruction to the central flame and prevent smoke from leaking through the discharge hole 15.

[0028] Please refer to Figure 2-Figure 4 As shown, a positioning hole 18 is provided on the lower surface of the movable cylinder 13, a mounting cavity 71 is provided on the upper part of the support rod 7, the top of the mounting cavity 71 passes through the fixed cylinder 8, an open slide groove 72 is provided on the upper part of the outer side of the support rod 7, the open slide groove 72 passes through the interior of the mounting cavity 71, a slider 19 is slidably installed in the interior of the mounting cavity 71, a positioning bolt 20 is provided on the top of the slider 19, and the positioning bolt 20 is adapted to the internal size of the positioning hole 18. When the filling is completed, the movable cylinder 13 is pulled outward, the feed hole 14 is misaligned with the docking hole 9, the limit table 12 is sealed to the bottom open of the discharge hole 15, and the positioning bolt 20 cooperates with the positioning hole 18 to keep the position of the movable cylinder 13 fixed.

[0029] Among them, a spring 21 is arranged at the lower part of the installation cavity 71, and the top of the spring 21 contacts the lower surface of the slider 19. A toggle bolt 22 is arranged on the outer side of the slider 19. The toggle bolt 22 passes through the open slide groove 72. The elastic force of the spring 21 is used to ensure that the slider 19 always has an upward force when not subject to external force. Then, after being pulled into place outside the movable cylinder 13, the positioning bolt 20 can automatically enter the positioning hole 18 to keep it fixed.

[0030] Please refer to Figure 1As shown, convex strips 23 are symmetrically arranged on both sides of the movable cylinder 13, and grooves corresponding to the convex strips 23 are symmetrically opened on both sides of the inner wall of the fixed cylinder 8, so that the movable cylinder 13 can only slide axially but cannot rotate, thereby ensuring that the feed hole 14 is always upward and the discharge hole 15 is always kept downward. A limit plate 24 is provided at one end of the convex strip 23 close to the rotating handle 17, and the limit plate 24 is placed on the outside of the fixed cylinder 8. When fuel is added, the movable cylinder 13 is pushed inward, and when the discharge hole 15 reaches the center position, the limit plate 24 is limited by the end face of the fixed cylinder 8 to achieve precise movement.

[0031] Working principle: First, fill the hopper 10 with the corresponding granular fuel. Due to the presence of the spring 21, the slider 19 always has an upward force. When fuel needs to be added, the toggle bolt 22 can be pressed down to move the slider 19 downward. At this time, the positioning bolt 20 is disengaged from the positioning hole 18, and then the movable cylinder 13 is pushed inward until the movable cylinder 13 is limited by the limiting plate 24. At this time, the discharge hole 15 is placed at the center of the furnace body 2, and the feed hole 14 coincides with the bottom of the docking hole 9. At this time, the granular fuel inside the hopper 10 will fall out. The particles fall into the movable cylinder 13 and are transported to the inside of the workbench 1 by rotating the external rotating handle 17 to rotate the spiral conveying shaft 16, and are discharged through the discharge hole 15 and fall into the central area of ​​the grate 11. After the feeding is completed, the movable cylinder 13 is pulled outward to move the discharge hole 15 to one side, and the feed hole 14 and the docking hole 9 are misaligned to stop feeding. When the positioning bolt 20 and the positioning hole 18 cooperate, the opening at the bottom of the discharge hole 15 is sealed by the limit table 12 to prevent the flame from entering the movable cylinder 13.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
