DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] It should be noted that granular fuel can be added to the mixing box 1 through the feed port 3. The granular fuel can be stirred more evenly and thoroughly through the stirring mechanism 2, and the stirring effect is better. The discharge mechanism 4 can make the granular fuel slide more smoothly, achieve a better discharge effect, and effectively reduce the residual granular fuel in the mixing box 1.

[0030] It should be noted that by starting the motor 21, the rotating shaft 22 rotates clockwise, thereby driving the four connecting plates 24 to rotate clockwise, and then driving the multiple stirring plates 25 to rotate clockwise, so that the granular fuel can be stirred. At the same time, the rotating shaft 22 will drive the bevel gear 28 to rotate clockwise, and the set bevel gear 28 and the two bevel gears 29 are meshed, thereby driving the right bevel gear 29 to move upward, and at the same time driving the left bevel gear 29 to rotate downward, so that the left and right connecting rods 26 rotate in the same speed and opposite directions, thereby driving the stirring plate 27 to rotate. The set connecting rod 26 is divided into two parts, upper and lower, so that the granular fuel can be stirred more evenly and thoroughly, and the stirring effect is better.
[0031] like Figure 2 , Figure 4 As shown, the stirring plate 27 is in the shape of a curved plate, and the bending directions of the stirring plates 27 located in the front and rear are opposite.
[0032] It should be noted that the rotation of the stirring plate 27 can stir the particle fuel more evenly and thoroughly.
[0033] like Figure 2-Figure 4 As shown, the connecting rod 26 is in a U-shaped rod shape, the connecting plate 24 is in an L-shaped plate shape, and the length of the connecting rod 26 is smaller than the length of the upper portion of the connecting plate 24 .
[0034] It should be noted that the connecting rod 26 and the connecting plate 24 rotate simultaneously, which can achieve a better stirring effect.

[0036] It should be noted that after the stirring is completed, the granular fuel will slide along the guide block 1 41 and the guide block 2 42 to the position of the discharge trough 46. At this time, the baffle 47 below and the discharge trough 46 completely overlap, so that the granular fuel will not fall. By rotating the rotating plate 44 clockwise, the baffle 47 will be driven to rotate clockwise, and then the baffle 47 will gradually separate from the discharge trough 46, so that the opening of the discharge trough 46 will gradually increase, so that the granular fuel can slide down smoothly. The guide block 1 41 and the guide block 2 42 are both inclined surfaces, so that the granular fuel can slide more smoothly. At the same time, under the rotation of the connecting plate 24 and the connecting rod 26, the accumulated granular fuel will be pushed, so as to achieve a better unloading effect, and effectively reduce the residual granular fuel in the mixing box 1.
[0037] like Figure 5 , Figure 6 As shown, the shape and size of the four discharge troughs 46 are consistent with the shape and size of the four baffles 47, and the shapes of the discharge troughs 46 and the baffles 47 are both conical plates.
[0038] It should be noted that the baffle 47 and the discharge chute 46 completely overlap, so that the particle fuel will not fall. When the baffle 47 rotates, the baffle 47 will gradually separate from the discharge chute 46, so that the opening of the discharge chute 46 will gradually increase.

The distance between guide block 1 41 and guide block 2 42 is consistent with the length of baffle 47, and the heights of guide block 1 41 and guide block 2 42 are consistent.
[0040] It should be noted that the guide block 1 41 and the guide block 2 42 are both inclined surfaces, so that the particle fuel can slide more smoothly.
[0041] like Figure 5 , Figure 6 As shown, a slide groove 45 is provided on the right side of the discharge hopper 43 . The slide groove 45 is in the shape of an annular groove, and the height of the slide groove 45 is consistent with the thickness of the rotating plate 44 .
[0042] It should be noted that the rotating plate 44 rotates smoothly, so that the opening of the discharge chute 46 can reach the minimum or maximum.
[0043] The working principle of the utility model is as follows: first, granular fuel is added into the mixing box 1 through the feed port 3, and the motor 21 is started to make the rotating shaft 22 rotate clockwise, thereby driving the four connecting plates 24 to rotate clockwise, thereby driving the multiple stirring plates 25 to rotate clockwise, thereby stirring the granular fuel, and at the same time, the rotating shaft 22 will drive the bevel gear 1 28 to rotate clockwise, and the set bevel gear 1 28 and the two bevel gears 29 are meshed, thereby driving the right bevel gear 29 to move upward, and at the same time driving the left bevel gear 29 to rotate downward, thereby making the left and right connecting rods 26 rotate in the same speed and opposite directions, thereby driving the stirring plate 27 to rotate, and the set connecting rod 26 is divided into two parts, the upper and lower parts, thereby making the granular fuel more Even and thorough stirring can achieve better stirring effect. After stirring is completed, the granular fuel will slide down the guide block 1 41 and the guide block 2 42 to the position of the discharge chute 46. At this time, the baffle 47 below and the discharge chute 46 completely overlap, so that the granular fuel will not fall. By rotating the rotating plate 44 clockwise, the baffle 47 will be driven to rotate clockwise, so that the baffle 47 gradually separates from the discharge chute 46, so that the opening of the discharge chute 46 gradually increases, so that the granular fuel can slide down smoothly. The guide block 1 41 and the guide block 2 42 are both inclined surfaces, so that the granular fuel can slide more smoothly. At the same time, under the rotation of the connecting plate 24 and the connecting rod 26, the accumulated granular fuel will be pushed, so as to achieve a better unloading effect and effectively reduce the residual granular fuel in the mixing box 1.
