[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] A bin body 1, a feed pipe 101 is fixedly connected to the upper part of the bin body 1, a rotating shaft 2 is rotatably connected to the inner wall of the bin body 1, and a sealing box 3 is fixedly connected to the end of the rotating shaft 2 on the side wall of the bin body 1;

[0031] A stirring assembly 4, which is fixedly connected to the side wall of the rotating shaft 2, and is used to stir the material itself by utilizing the impact force when the material enters the bin body 1;

[0032] The scraper assembly 5 is slidably connected to the inner wall of the bin body 1, and the scraper assembly 5 is used to rotate and scrape the bottom of the bin body 1 to avoid material blockage.

[0033] Reference Figure 5 , Figure 6 , wherein the stirring assembly 4 includes a circular plate 41, the circular plate 41 is fixedly connected to the side wall of the rotating shaft 2, a gap is provided on the end surface of the circular plate 41, and the circular plate 41 corresponds to the outlet of the feed pipe 101;

[0034] Reference Figure 5 , Figure 6 , wherein a serpentine groove 42 is provided inside the circular plate 41, a serpentine plate 43 is sealingly and slidably connected to the inner wall of the serpentine groove 42, and a spring 44 is fixedly connected between the serpentine plate 43 and the bottom of the serpentine groove 42;

[0035] By setting the above structure, when the biomass enters the interior of the silo 1 through the feed pipe 101, it will impact the circular plate 41. Under the action of the pipeline conveying force and the gravity of the biomass itself, the circular plate 41 will drive the rotating shaft 2 to rotate, so that the multiple circular plates 41 can realize the flipping effect together, and can stir the biomass material falling into the silo 1. In addition, since the end surface of the circular plate 41 is provided with multiple gaps, the biomass material that has condensed into blocks can be broken up during the process of the biomass material impacting the circular plate 41, which improves the production quality of the biomass material and avoids the situation where the biomass material that has condensed into blocks blocks the silo 1, thereby improving the conveying efficiency of the device;

[0036] And when the biomass material impacts the serpentine plate 41, the serpentine plate 43 facing the feed pipe 101 will swing up and down under the action of the spring 44, thereby reducing the impact of the biomass material and avoiding the situation where the silo 1 is damaged due to the different loads of the biomass material, thereby increasing the service life of the silo 1.

[0037] Reference Figure 1 , wherein a heating pump is arranged at the bottom of the left sealed box 3, the output end of the heating pump is connected to the inside of the sealed box 3, a condenser pipe 31 is fixedly connected to the bottom of the right sealed box 3, and a rotary valve 32 is arranged on the side wall of the condenser pipe 31;

[0038] Reference Figure 4, wherein, air guide bins 21 are provided at both ends of the rotating shaft 2, the air guide bins 21 are communicated with the inner cavity of the sealing box 3, the inner wall of the air guide bin 21 is fixedly connected with driving blades 22, the number of driving blades 22 arranged on the inner wall of the single-side air guide bin 21 is three, a heating bin 45 is provided inside the serpentine plate 43, and the heating bin 45 is communicated with the air guide bin 21;

[0039] Through the arrangement of the above structure, the heating pump passes the hot air into the air guide bin 21 through the sealing box 3, and then disperses it into the heating bin 45 inside the plurality of serpentine plates 43, so as to heat the serpentine plates 43. When the biomass material contacts the serpentine plates 43, the biomass material will be dried, and along with the rotation of the serpentine plates 43, the above heat effect can be evenly distributed inside the bin body 1, so as to improve the drying effect of the device;

[0040] After the hot air flows through each serpentine plate 43, it will flow into the condensation tube 31 from the air guide chamber 21 at the other end, so as to condense the hot air after the drying effect is exerted, and form a passage for the entire drying duct, which can not only ensure that the serpentine plate 43 continues to maintain a good drying effect, thereby further improving the drying effect of the device, but also can use the driving force generated by the air flow to make the driving blade 22 rotate, so that the shaft 2 can rotate better, so that the serpentine plate 43 can have a drying effect while obtaining a better driving force, thereby making the operation of the entire device smoother and improving the practicality of the device.

[0041] Reference Figure 3 , Figure 5 The scraper assembly 5 includes a driving disc 51, which is slidably connected to the inner wall of the bin body 1, a driving toothed disc 52 is fixedly connected to the upper part of the driving disc 51, a scraper rod 53 is fixedly connected to the bottom of the driving disc 51, and a gear 54 is fixedly connected to the side wall of the rotating shaft 2, and the gear 54 is meshed with the driving toothed disc 52;

[0042] Reference Figure 2 , Figure 4 , wherein the inner wall of the bin body 1 is located above the driving gear disc 52 and is fixedly connected with an anti-stuck disk 6, the inner wall of the bin body 1 is located outside the gear 54 and is fixedly connected with an anti-stuck box 61, the bottom of the anti-stuck box 61 is fixedly connected to the anti-stuck disk 6, and the upper part of the anti-stuck box 61 and the anti-stuck disk 6 are both arranged in a slope arc shape;

[0044] By setting the above structure, when the rotating shaft 2 rotates, due to the meshing connection between the gear 54 and the driving toothed disc 52, the driving toothed disc 52 will also drive the driving disc 51 to rotate, so that the scraper rod 53 can rotate in contact with the inner wall of the bin body 1. In this process, the moisture content of the biomass material can be detected by the moisture detection device, which is convenient for controlling the quality of the biomass material. With the rotation of the scraper rod 53, the biomass material at the bottom of the side wall of the bin body 1 can be scraped to avoid the adhesion and blockage of the biomass material, thereby improving the fluidity of the device; and the anti-stuck box 61 and the anti-stuck disc 6 with a slope arc at the upper part can prevent the biomass material from hindering the rotation of the gear 54 and the driving toothed disc 52, thereby improving the rationality of the device and ensuring that the device can operate stably; and the side wall of the scraper rod 53 is hollowed out, which can greatly reduce the friction between the scraper rod 53 and the biomass material, slow down the squeezing effect on the biomass material, thereby improving the output quality of the biomass material.

[0045] Reference Figure 1-6 In the present invention, when the biomass enters the interior of the silo 1 through the feed pipe 101, it will impact the circular plate 41. Under the action of the pipeline conveying force and the biomass' own gravity, the circular plate 41 will drive the rotating shaft 2 to rotate, so that the multiple circular plates 41 can realize the flipping effect together, and can stir the biomass material falling into the silo 1. In addition, since the end surface of the circular plate 41 is provided with multiple gaps, in the process of the biomass material impacting the circular plate 41, the biomass material that has condensed into blocks can be broken up, which improves the production quality of the biomass material and avoids the situation that the biomass material that has condensed into blocks blocks the silo 1, thereby improving the conveying efficiency of the device; and in the process of the biomass material impacting the circular plate 41, the serpentine plate 43 facing the feed pipe 101 will shake up and down under the action of the spring 44, thereby reducing the impact of the biomass material and avoiding the situation that the silo 1 is damaged due to the different loads of the biomass material, thereby improving the service life of the silo 1;

[0046] At the same time, the heating pump passes the hot air into the air guide bin 21 through the sealing box 3, and then disperses it into the heating bin 45 inside the multiple serpentine plates 43, so as to heat the serpentine plates 43. When the biomass material contacts the serpentine plates 43, the biomass material will be dried, and along with the rotation of the serpentine plates 43, the above-mentioned heat effect can be evenly distributed to the inside of the bin body 1, thereby improving the drying effect of the device; after the hot air flows through each serpentine plate 43, it will flow into the condensation pipe 31 from the air guide bin 21 at the other end, so as to condense the hot air after the drying effect is exerted, and form a passage for the entire drying pipeline, which can not only ensure that the serpentine plates 43 continue to maintain a good drying effect, thereby further improving the drying effect of the device, but also can generate a driving force when the air flow flows, so that the driving blades 22 are rotated, so that the rotating shaft 2 can be better rotated, so that the serpentine plates 43 have a drying effect, and can also obtain a better driving force, so that the operation of the entire device is smoother, and the practicality of the device is improved;

[0047] When the rotating shaft 2 rotates, due to the meshing connection between the gear 54 and the driving gear disc 52, the driving gear disc 52 will also drive the driving disc 51 to rotate, so that the scraper rod 53 rotates in contact with the inner wall of the bin body 1. As the scraper rod 53 rotates, the biomass material at the bottom of the side wall of the bin body 1 can be scraped to avoid the adhesion and blockage of the biomass material, thereby improving the fluidity of the device; and the anti-stuck box 61 and the anti-stuck disc 6 with a sloped arc at the upper part can avoid the biomass material from hindering the rotation of the gear 54 and the driving gear disc 52, thereby improving the rationality of the device and ensuring that the device can operate stably; and the side wall of the scraper rod 53 is hollowed out, which can greatly reduce the friction between the scraper rod 53 and the biomass material, slow down the squeezing effect on the biomass material, thereby improving the output quality of the biomass material.
