DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model below, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0024] REFERENCE Figures 1-4An embodiment of this utility model provides a wood pellet dispensing device for biomass pellet production, comprising a shield 1 and a mixing tank 4. A support frame 2 is fixedly connected to the bottom of the shield 1. A conveyor belt 3 is provided on the inner wall of the shield 1. A dispersing component is provided on the inner wall of the mixing tank 4. The dispersing component includes two rotating shafts 14 rotatably connected to the inner wall of the mixing tank 4. A first auger 17 is fixedly connected to the outer wall of each rotating shaft 14. Multiple push plates 15 are fixedly connected to the front side of the outer wall of the left rotating shaft 14. Multiple push plates 15 are fixedly connected to the rear side of the outer wall of the right rotating shaft 14. A drive motor 6 is fixedly connected to the right front end of the mixing tank 4. The front end of the right rotating shaft 14 is fixedly connected to the drive end of the drive motor 6. Transmission gears 16 are fixedly connected to the rear side of the outer wall of each rotating shaft 14. The two transmission gears 16 are meshed. A partition 5 is fixedly connected between the two rotating shafts 14 on the inner wall of the mixing tank 4. The partition 5 is used to divide the mixing tank 4 into two cavities for material circulation.

[0025] Specifically, the wood chips on the right side of the partition 5 will be pushed towards the rear of the mixing tank 4 by the first auger 17 on the right. When they reach the rear, they will be pushed to the left side of the partition 5 by the push plate 15 on the right. Then, they will be pushed towards the front of the mixing tank 4 by the first auger 17 on the left. When they reach the front, they will be pushed to the right side of the partition 5 by the push plate 15 on the left. This cycle will distribute the wood chips that fall into the mixing tank 4, so that they will not accumulate in the middle of the mixing tank 4. The bottom of the mixing tank 4 has multiple through holes. The size of the through holes is the same as that of the metering groove 20 on the distributor 19 and their positions are corresponding. This will ensure that the wood chips at the bottom of the mixing tank 4 will continuously enter the metering groove 20 under the push of the first auger 17. There will be no wood chips accumulating on the surface of the distributor 19 and being too far away from the first auger 17, which would prevent the wood chips from accumulating and entering the production process.

[0026] A distributing trough 8 is fixedly connected to the bottom of the mixing tank 4. A second drive motor 7 is fixedly connected to the front end of the distributing trough 8. A second rotating shaft 18 is fixedly connected to the drive end of the second drive motor 7. A distributor 19 is fixedly connected to the outer wall of the second rotating shaft 18. The outer wall of the second rotating shaft 18 is rotatably connected to the inner wall of the distributing trough 8. The outer wall of the distributor 19 is attached to the inner wall of the distributing trough 8. Fixed legs 9 are fixedly connected to both the front and rear sides of the bottom of the distributing trough 8. Multiple metering grooves 20 are opened at both the top and bottom of the distributor 19. Multiple discharge pipes 10 are fixedly connected. A conveying assembly is provided at the bottom of each discharge pipe 10. The conveying assembly includes a conveying trough 11 located at the bottom of each discharge pipe 10. A drive motor 13 is fixedly connected to the right end of each conveying trough 11. A rotating shaft 21 is fixedly connected to the drive end of each drive motor 13. A second auger 22 is fixedly connected to the outer wall of each rotating shaft 21. The outer wall of each rotating shaft 21 is rotatably connected to the inner wall of the conveying trough 11. A discharge port 12 is opened on the right side of the bottom end of each conveying trough 11.

[0027] Specifically, when the driving motor one 6 drives the rotating shaft one 14 to spread the sawdust in the mixing tank 4, the driving motor two 7 is first stopped for a period of time, so that the distributor 19 blocks the sawdust in the mixing tank 4 to form a pile, and then the driving motor two 7 is started to drive the distributor 19 to rotate, so that the quantitative groove 20 on the distributor 19 can drive the sawdust into the inside of the discharge pipe 10 for distribution and discharge. At this time, the sawdust transported into the mixing tank 4 by the conveying belt 3 will be continuously spread under the action of the first auger 17, and the bottom of the mixing tank 4 will always accumulate a certain amount of sawdust under the replenishment of the conveying belt 3, which can enter the inside of the quantitative groove 20 for feeding to ensure that the amount of sawdust transported into the pelletizer is the same, the proportion of sawdust in the product is consistent, and the sawdust transported into the mixing tank 4 by the conveying belt 3 is prevented from directly falling from the two through holes in the middle of the mixing tank 4, which affects the product quality due to the small amount of sawdust in the conveying groove 11 on both sides.

[0028] Working principle: the sawdust in the material pool is transported by the conveying belt 3 and falls into the inside of the mixing tank 4. The driving motor one 6 is started to drive the right rotating shaft one 14 to rotate. The right rotating shaft one 14 is driven to rotate in the transmission gear 16, which drives the left rotating shaft one 14 to rotate in the opposite direction synchronously, so that the sawdust falling into the inside of the mixing tank 4 is moved under the action of the two first augers 17 driven by the rotating shaft one 14 to spread in the inside of the mixing tank 4. When the sawdust in the inside of the mixing tank 4 accumulates to a certain height, the driving motor two 7 is started to drive the rotating shaft two 18 to rotate, so that the distributor 19 rotates to send the sawdust in the quantitative groove 20 to the upper side of the discharge pipe 10 and then to the inside of the corresponding conveying groove 11. Finally, the driving motor three 13 drives the rotating shaft three 21 to drive the second auger 22 to rotate to transport the sawdust in the conveying groove 11 to the discharge port 12 and then to the pelletizer for production. The device can ensure that the amount of sawdust transported in each conveying groove 11 is consistent, and the proportion of sawdust is the same when produced in the pelletizer, which improves the product quality.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
