[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 One embodiment provided by this utility model:

Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A quantitative feeding device for straw biomass includes a frame, which includes a support frame 1. A hopper 11 is arranged inside the support frame 1. A support block 12 is fixedly connected to the surface of the hopper 11. A weighing sensor 13 is fixedly installed on the upper surface of the support frame 1. The end of the weighing sensor 13 away from the support frame 1 is connected to the support block 12. A conveying bin 14 is fixedly connected to the bottom end of the hopper 11. A screw conveying rod 15 is movably connected to the inner side of the conveying bin 14. A first motor 16 is fixedly installed on the surface of the conveying bin 14. The output end of the screw conveying rod 15 is fixedly connected to the output end of the first motor 16. A discharge port 17 is fixedly connected to the lower surface of the conveying bin 14. The support frame 1 supports the hopper 11. The weighing sensor 13 weighs the straw feed, enabling quantitative feeding. The first motor 16 drives the screw conveying rod 15 to rotate, thus conveying the straw and discharging it through the first motor 16, completing the feeding process.

[0024] A cleaning mechanism is provided inside the conveying chamber 14. The cleaning mechanism includes a connecting frame 2, which is fixedly connected to the surface of the conveying chamber 14. A threaded rod 21 is movably connected to the inside of the connecting frame 2. A second motor 22 is fixedly installed on the surface of the connecting frame 2. A first moving block 23 is movably connected to the surface of the threaded rod 21. A scraper 24 is fixedly connected to the surface of the first moving block 23. A connecting rod 25 is fixedly connected to the surface of the scraper 24. By setting the scraper 24, when the scraper 24 moves, it cooperates with the reverse rotation of the screw conveyor 15 to cut the straw wrapped on the screw conveyor 15, so that the straw can be removed from the screw conveyor 15, thereby facilitating the cleaning of the screw conveyor 15 and ensuring the stable operation of the device.

[0025] Furthermore, the cleaning mechanism also includes a limiting rod 26, which is fixedly connected to the inner wall of the connecting frame 2. The first moving block 23 is movably connected to the limiting rod 26. The inner side of the conveying chamber 14 is provided with a movable groove 27, and the first moving block 23 moves within the movable groove 27. By setting the limiting rod 26, the first moving block 23 can be prevented from shifting under the action of the threaded rod 21, which facilitates the first moving block 23 to drive the scraper 24 to move stably, thereby realizing the cleaning of the spiral conveying rod 15 by the scraper 24.

[0026] Furthermore, the threaded rod 21 is fixedly connected to the output end of the second motor 22, the scraper 24 is sleeved on the surface of the screw conveyor 15 and moves inside the conveying chamber 14, the connecting rod 25 is fixedly connected to the scraper 24 in two sets, and the first moving block 23 can drive the scraper 24 to move by rotating the threaded rod 21. In the process of the scraper 24 moving, it can cut the straw wrapped on the screw conveyor 15, thereby cleaning the screw conveyor 15.

[0027] Furthermore, an anti-blocking mechanism is provided on the inner side of the hopper 11. The anti-blocking mechanism includes a connecting plate 3, which is fixedly connected to the surface of the hopper 11. A reciprocating screw 31 is movably connected to the inner side of the connecting plate 3. A third motor 32 is fixedly installed on the top of the connecting plate 3. A fixing plate 33 is movably connected to the surface of the reciprocating screw 31. A fixing rod 34 is fixedly connected to the lower surface of the fixing plate 33. A crushing blade 35 is fixedly connected to the surface of the fixing rod 34. A limiting block 36 is fixedly connected to the surface of the fixing plate 33. A limiting groove 37 is opened on the inner surface of the connecting plate 3. With the setting of the fixing rod 34 and the crushing blade 35, the straw can be crushed and the bottom of the hopper 11 can be cleared during the lifting process. This can prevent the straw from accumulating and blocking at the bottom of the hopper 11, so that the straw can enter the conveying chamber 14 better after entering the hopper 11, thereby realizing the conveying by the screw conveyor 15.

[0028] Furthermore, one end of the reciprocating screw 31 is movably connected to the connecting plate 3, and the other end of the reciprocating screw 31 is fixedly connected to the output end of the third motor 32. The fixed rod 34 and the crushing blade 35 are both movable inside the hopper 11. By rotating the reciprocating screw 31, the fixed plate 33 can drive the fixed rod 34 and the crushing blade 35 to move vertically, which facilitates the crushing of the straw in the hopper 11, thus making it easier for the straw to enter the conveying bin 14.

[0029] Furthermore, the crusher blades 35 are fixedly connected to the fixed rods 34 in eight groups. One end of the limiting block 36 is fixedly connected to the fixed plate 33, and the other end of the limiting block 36 is movably connected to the limiting groove 37. By setting the limiting block 36 and opening the limiting groove 37, the movement of the fixed plate 33 can be limited, which can prevent the fixed plate 33 from shifting under the action of the reciprocating screw 31, and facilitate the fixed rods 34 to drive the crusher blades 35 to move vertically in a stable manner.

[0030] Working principle: During use, the second motor 22 is electrically connected to an external power source. The operator starts the second motor 22 by pressing the switch. The second motor 22 drives the threaded rod 21 to rotate. The first moving block 23 is limited by the limiting rod 26 and moves inside the connecting frame 2 and the movable groove 27 under the action of the threaded rod 21. This allows the first moving block 23 to move on the surface of the limiting rod 26. Consequently, the leftmost scraper 24 moves accordingly, and the connecting rod 25 drives the other scrapers 24 to move as well. The movement of the scrapers 24 can cut the straw wrapped around the spiral conveyor rod 15. At the same time, the first motor 16 drives the spiral conveyor rod 15 to reverse, which can remove the straw from the spiral conveyor rod 15, thus cleaning the spiral conveyor rod 15. After cleaning, the scrapers 24 can be moved into the gap between the spiral conveyor rods 15.

[0031] The third motor 32 is electrically connected to an external power source. The operator starts the third motor 32 by pressing a switch. The operation of the third motor 32 drives the reciprocating screw 31 to rotate. The fixed plate 33 is limited by the limiting block 36 and the limiting groove 37. Under the action of the reciprocating screw 31, it will perform vertical reciprocating motion, so that the limiting block 36 can move inside the limiting groove 37. Then, the fixed rod 34 will drive the crushing blade 35 to move vertically under the action of the fixed plate 33. During the movement of the crushing blade 35, it can cut and crush the straw, and at the same time, it can clear the bottom of the hopper 11, so that the straw can enter the conveying hopper 14 better.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
