[0014] Beneficial effects of the present invention:

[0015] The present invention utilizes the upward hot air generated when the combustion device is working, and the power source formed is used to drive the distribution drum with a plurality of hot air fan blades installed on the circumference to rotate, so as to pour the biomass fuel into the feeding device, and then the feeding device is fed to the inside of the device shell above the combustion device, and the fuel enters the distribution drum through the inlet pipe, and then cooperates with the round table in the distribution drum to flow out from the discharge rectangular tube. Since the hot air in the combustion device drives the distribution drum with hot air fan blades installed on the circumference to rotate through the distribution screen plate, the biomass fuel flowing out from the discharge rectangular tube is evenly scattered on the distribution screen plate, and falls into the combustion device through the distribution screen plate for combustion;

[0016] When the material distribution drum of the present invention rotates, the reciprocating screw connected to the upper side of the internal truncated table is threadedly connected to the movable frame sliding in the feed inlet pipe. The rotating reciprocating screw causes the movable frame to slide up and down in the feed inlet pipe, and the dredging frames installed at the four corners of the upper side of the movable frame dredge the blocked feed inlet pipe to keep the conveying pipe port unobstructed, so that the equipment continues to work normally.

[0017] The blades on one side fan plate of the present invention cooperate with the blades on the other side fan plate to chop up the large pieces of biomass fuel remaining on the sub-screen plate, so that the fuel enters the combustion equipment through the sub-screen plate. The chopped small pieces of biomass fuel are easier to burn, avoiding the blockage of the sub-screen plate, improving the feeding efficiency of the equipment, and indirectly improving the combustion quality and efficiency of the equipment.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-6 , a biomass raw material uniform feeding device, comprising a combustion device 1 and a feeding device 2, the feeding device 2 is installed on one side of the combustion device 1, a device shell 3 is fixedly installed on the upper side of the combustion device 1, a feed port pipe 4 is fixedly installed on the center upper side of the device shell 3, a sub-screen plate 8 located in the device shell 3 is installed on the upper side of the combustion device 1, the inside of the device shell 3 is connected with the inside of the combustion device 1, and a plurality of sub-screen openings are evenly opened on the sub-screen plate 8. By using the biomass raw material uniform feeding device, the feeding device 2 can evenly pour the biomass fuel into the combustion device 1, so that the biomass fuel burns more thoroughly and fully, and the combustion effect and quality of the combustion device 1 are higher;

[0027] Furthermore, a fixed base 9 is fixedly installed at the center of the sub-screen plate 8, a rotatably connected sub-drum 5 is arranged between the fixed base 9 and the feed inlet pipe 4, and a plurality of hot air fan blades 6 are evenly installed on the circumference of the sub-drum 5. The device utilizes the upward hot air generated when the combustion device 1 is working, and the power source formed is used to drive the sub-drum 5 with a plurality of hot air fan blades 6 installed on the circumference to rotate, pour the biomass fuel into the feeding device 2, and then the feeding device 2 feeds the biomass fuel to the inside of the device housing 3 above the combustion device 1;

[0028] Furthermore, a plurality of discharge rectangular tubes 7 are evenly fixed on the circumference of the distribution drum 5 on the lower side of the hot air fan blades 6, the discharge rectangular tubes 7 are communicated with the inside of the distribution drum 5, a truncated cone 15 is installed inside the distribution drum 5, the inclined surface of the truncated cone 15 coincides with the lower side surface of the internal channel of the discharge rectangular tube 7, the fuel enters the distribution drum 5 through the inlet pipe 4, and then cooperates with the truncated cone 15 in the distribution drum 5 to flow out from the discharge rectangular tube 7, because the hot air in the combustion equipment 1 drives the distribution drum 5 with the hot air fan blades 6 installed on the circumference to rotate through the sieve plate 8, so that the biomass fuel flowing out from the discharge rectangular tube 7 is evenly scattered on the sieve plate 8, and falls into the combustion equipment 1 through the sieve plate 8 for combustion;

[0029] Furthermore, a movable frame 13 is arranged inside the feed inlet pipe 4, and a plurality of dredging frames 14 are evenly installed on the upper side of the movable frame 13. Slide rods 12 are fixed on both sides of the feed inlet pipe 4, and the two slide rods 12 respectively penetrate the left and right sides of the movable frame 13, and a limited block is fixed at the lower end of the slide rod 12. A reciprocating screw rod 11 is fixedly installed at the center of the upper side of the round table 15, and the reciprocating screw rod 11 is threadedly connected to the movable frame 13. When the material distribution drum 5 rotates between the feed inlet pipe 4 and the fixed base 9, the biomass fuel inside the material distribution drum 5 is moved in a direction of rotation. When entering the feed inlet pipe 4, material blockage may occur, resulting in the inlet pipe being unable to be unblocked, affecting the normal operation of the equipment. When the material distribution drum 5 rotates, the reciprocating screw 11 connected to the upper side of the internal truncated table 15 is threadedly connected to the movable frame 13 sliding in the feed inlet pipe 4. The rotating reciprocating screw 11 makes the movable frame 13 slide up and down in the feed inlet pipe 4, and the unblocking frames 14 installed at the four corners of the upper side of the movable frame 13 unblock the blocked feed inlet pipe 4, so as to keep the conveying pipe port unblocked and the equipment continues to work normally.

[0030] Furthermore, two fan plates 16 are provided at the lower end of the material distribution drum 5, and an L-shaped fixing block 18 is fixedly installed on the fan plates 16. A polygonal protrusion 10 located between the two L-shaped fixing blocks 18 is fixed on the central upper side of the fixed base 9, and a plurality of cutting blades 17 are evenly fixedly installed on the lower side of the outer end of the fan plate 16. A slide groove 19 corresponding to the upper end of the L-shaped fixing block 18 is opened inside the lower end of the material distribution drum 5, and a slide rod 20 passing through the L-shaped fixing block 18 is provided in the slide groove 19, and a spring 21 located in the slide groove 19 is sleeved on the circumference of the slide rod 20. When the material distribution drum 5 rotates, the two fan plates 16 arranged on the lower side thereof follow the rotation to help the biomass fuel remaining on the dividing screen plate 8 fall into the combustion equipment 1, and the fan plates 16 on the lower side follow the rotation of the material distribution drum 5 When the two L-shaped fixing blocks 18 move, the polygonal protrusions 10 between the two L-shaped fixing blocks 18 form intermittent pressure on the connected fan plates 16. When the convex parts of the polygonal protrusions 10 are touched, the two fan plates 16 move to the two outer sides respectively. When the polygonal protrusions 10 rotate and the concave parts contact the fan plates 16, the elastic force of the springs 21 in the slide grooves 19 causes the two outwardly moved fan plates 16 to return to their original positions. In this way, the fan plates 16 move back and forth rapidly relative to each other, and the cutting blades 17 installed on the lower sides of the fan plates 16 also follow the movement. The blades on the fan plates 16 on one side cooperate with the blades on the fan plates 16 on the other side to chop up the large pieces of biomass fuel remaining on the sub-screen plate 8, so that the fuel passes through the sub-screen plate 8 into the combustion equipment 1. The chopped small pieces of biomass fuel are easier to burn, thus avoiding the blockage of the sub-screen plate 8.

[0031] The specific working principle of the present invention is as follows:

[0032] By using the biomass raw material uniform feeding device, the feeding device 2 can evenly pour the biomass fuel into the combustion device 1, so that the biomass fuel burns more thoroughly and fully, and the combustion effect and quality of the combustion device 1 are higher;

[0033] This device utilizes the upward hot air generated when the combustion device 1 is working, and the power source formed is used to drive the distribution drum 5 with a plurality of hot air fan blades 6 installed on the circumference to rotate, and the biomass fuel is poured into the feeding device 2, and then the feeding device 2 is fed to the inside of the device housing 3 above the combustion device 1, and the fuel enters the distribution drum 5 through the inlet pipe 4, and then cooperates with the round table 15 in the distribution drum 5 to flow out from the discharge rectangular tube 7. Since the hot air in the combustion device 1 drives the distribution drum 5 with hot air fan blades 6 installed on the circumference to rotate through the sub-screen plate 8, the biomass fuel flowing out from the discharge rectangular tube 7 is evenly scattered on the sub-screen plate 8, and falls into the combustion device 1 through the sub-screen plate 8 for combustion;

[0034] When the material distribution drum 5 rotates between the feed inlet pipe 4 and the fixed base 9, the biomass fuel inside the material distribution drum 5 may be blocked when entering the feed inlet pipe 4, resulting in the inlet pipe being unable to be unblocked, affecting the normal operation of the equipment. When the material distribution drum 5 rotates, the reciprocating screw 11 connected to the upper side of the internal truncated table 15 is threadedly connected to the movable frame 13 sliding in the feed inlet pipe 4. The rotating reciprocating screw 11 makes the movable frame 13 slide up and down in the feed inlet pipe 4, and the unblocking frames 14 installed at the four corners of the upper side of the movable frame 13 unblock the blocked feed inlet pipe 4 to keep the conveying pipe opening unblocked, so that the equipment continues to work normally.

[0035] When the material distribution drum 5 rotates, the two fan plates 16 arranged on the lower side thereof rotate accordingly, helping the biomass fuel remaining on the sub-screen plate 8 to fall into the combustion equipment 1. When the lower fan plate 16 rotates along with the material distribution drum 5, the polygonal protrusions 10 between the two L-shaped fixing blocks 18 form intermittent pressure on the connected fan plates 16. When the convex parts of the polygonal protrusions 10 are touched, the two fan plates 16 move to the outer sides respectively. When the polygonal protrusions 10 rotate and the concave parts contact the fan plates 16, they are acted upon by the elastic force of the springs 21 in the slide slots 19. The two outwardly moved fan plates 16 return to their original positions and move back and forth rapidly relative to each other. The cutting blades 17 installed on the lower sides of the fan plates 16 also follow the movement. The blades on one side of the fan plate 16 cooperate with the blades on the other side of the fan plate 16 to chop up the large pieces of biomass fuel remaining on the sub-screen plate 8, so that the fuel enters the combustion equipment 1 through the sub-screen plate 8. The chopped small pieces of biomass fuel are easier to burn, avoiding blockage of the sub-screen plate 8, improving the feeding efficiency of the equipment, and indirectly improving the combustion quality and efficiency of the equipment.
