If it is not cleaned for a long time, the materials will deteriorate, and the deteriorated materials will fall and mix with other materials, which will easily affect the quality of the finished product. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a straw granulator which is convenient for inner chamber dust removal. The straw granulator which is convenient for inner chamber dust removal comprises a barrel 1, the interior of the barrel 1 is rotatably connected with a mounting shaft 2, a lower barrel 3 is clamped on the upper surface of the barrel 1, a dust removal mechanism is arranged outside the mounting shaft 2, the dust removal mechanism comprises a long plate 4, a scraper 5, a long axis 7, a closing plate 8 and a stirring plate 9, the long plate 4 is arranged outside the mounting shaft 2, there are two scrapers 5, the two scrapers 5 are respectively fixedly mounted on the two ends of the long plate 4, the long axis 7 is arranged on the upper surface of the long plate 4, the closing plate 8 is fixedly mounted on the outside of the long axis 7, there are two stirring plates 9, the two stirring plates 9 are both arranged outside the long axis 7, a circular plate 10 is fixedly mounted on a side of the lower barrel 3 close to the barrel 1, the circular plate 10 is slidably connected to the outside of the long axis 7, and the circular plate 10 is located between the stirring plate 9 and the closing plate 8.

[0028] By setting the scraper 5 and cooperating with the closing plate 8, when the straw granulator is working, when the material enters the discharge barrel 3, the stirring plate 9 stirs the material, and at the same time, the continuous rotation of the closing plate 8 opens and closes the opening formed by the circular plate 10 so as to control the amount of material entering the barrel 1, to avoid the material being blocked in the discharge barrel 3 and the excessive material entering the barrel 1 affecting the work of the pressing roller. At the same time, the long plate 4 drives the scraper 5 to rotate under the action of the mounting shaft 2. At this time, the scraper 5 scrapes off the dust attached to the inner wall of the inner bore of the barrel 1, and the scraped material falls to the pressing roller and is made into particles, so as to prevent the material from being attached to the inner wall for a long time and deteriorating and falling and mixing with other materials to affect the quality of the finished product. At the same time, the scraper 5 removes the dust attached to the inner wall of the inner bore at the same time to avoid the mixture of dust and material corroding the inner wall.

[0029] The outside of the installation shaft 2 is fixedly installed with a connecting shaft 11, and a groove 12 is provided on the outside of the connecting shaft 11. The long plate 4 is slidably connected to the inside of the groove 12, which is convenient for the disassembly and assembly of the long plate 4. The outside of the long shaft 7 is fixedly installed with a threaded rod 13, and the inside of the groove 12 is provided with an internal thread 14. The threaded rod 13 is threadedly connected to the inside of the internal thread 14, and the long plate 4 is slidably connected to the outside of the threaded rod 13, which is convenient for reinforcing the installation of the long plate 4. By setting the threaded rod 13 and cooperating with the placement groove 16, the lower barrel 3 is pulled upward to release the connection between the lower barrel 3 and the cylinder body 1. At this time, the stirring plate 9 rotates into the inside of the placement groove 16 to release the connection between the circular plate 10 and the long shaft 7. At this time, the long shaft 7 is rotated to release the connection between the threaded rod 13 and the internal thread 14. At this time, the long plate 4 is pulled upward to release the connection between the long plate 4 and the groove 12. At this time, the scraper 5 is disassembled, and the staff cleans the scraper 5 to ensure the cleaning effect of the scraper 5.

[0030] Two rotating shafts 15 are arranged on the outside of the long axis 7, and the two stirring plates 9 are respectively rotatably connected to the outside of the two rotating shafts 15, so as to facilitate the rotation of the stirring plates 9. Two placement grooves 16 are opened on the outside of the long axis 7, and the two rotating shafts 15 are respectively fixedly connected to the inside of the two placement grooves 16, so as to facilitate the storage of the stirring plates 9.

[0031] An opening 17 is provided on the outside of the long plate 4, and the long plate 4 is slidably connected to the outside of the threaded rod 13 through the opening 17, which facilitates the release of the connection between the long plate 4 and the threaded rod 13. A through hole 18 is provided on the outside of the circular plate 10, and the circular plate 10 is slidably connected to the outside of the long axis 7 through the through hole 18, which facilitates the release of the connection between the circular plate 10 and the long axis 7. A support plate 6 is fixedly installed on the inner side of the unloading barrel 3, and the long axis 7 is slidably connected to the inner side of the support plate 6, which facilitates the stable rotation of the long axis 7.

[0032] Working principle:

[0033] In the first step, the long plate 4 is placed in the groove 12. At this time, the threaded rod 13 is threadedly connected to the inner thread 14 through the opening 17 to fix the long plate 4 in the groove 12. At this time, the scraper 5 is in contact with the inner wall of the inner bore of the cylinder 1. At this time, the circular plate 10 outside the lower barrel 3 is slidably connected to the outside of the long shaft 7 through the through hole 18. At this time, the lower barrel 3 can be moved until the lower barrel 3 is clamped on the outside of the cylinder 1, and the stirring plate 9 is rotated to rotate out of the placement groove 16;

[0034] In the second step, when the straw pelletizer is working, the installation shaft 2 drives the connecting shaft 11 and the long shaft 7 to rotate. When the material enters the discharge barrel 3, the long shaft 7 drives the stirring plate 9 and the closing plate 8 to rotate. The stirring plate 9 stirs the material. At the same time, the continuous rotation of the closing plate 8 opens and closes the opening formed by the circular plate 10 to control the amount of material entering the barrel 1, avoiding the material from being blocked in the discharge barrel 3 and the excessive material entering the barrel 1 affecting the work of the pressing roller. At the same time, the long plate 4 drives the scraper 5 to rotate under the action of the installation shaft 2. At this time, the scraper 5 scrapes off the dust attached to the inner wall of the inner bore of the barrel 1.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
