DETAILED DESCRIPTION

[0017] The specific embodiments of the present application will be further described in detail. Figures 1-5 The specific embodiments of the present application will be further described in detail.

[0018] In the embodiment one, the scraper 9 is elastically connected with the adjusting device 7 through the mounting plate 8, and can be tightly attached to the inner wall of the stirring barrel 1 under the action of the adjusting device 7. Even if the scraper 9 is worn due to frequent use, the scraper 9 can still be attached to the inner wall of the stirring barrel 1 under the action of the adjusting device 7, so as to ensure the scraping effect of the scraper 9 on the residual materials on the inner wall of the stirring barrel 1.

[0019] In the embodiment two, the spring 13 is in a compressed state and the scraper 9 abuts against the inner wall of the stirring barrel 1. When the special mortar is stirred, the motor 23 on the rack 22 of the power device 6 is started, the output shaft 24 of the motor 23 drives the driving pulley 25 to rotate synchronously, the driving pulley 25 drives the stirring shaft 3 to rotate around the support 2 through the belt 26 and the driven pulley 5, the stirring rod 4 rotates synchronously with the stirring shaft 3, so as to stir and mix the special mortar. The scraper 9 on the adjusting device 7 and the mounting plate 8 rotates synchronously with the stirring rod 4, so as to scrape the residual materials on the stirring barrel 1. Figure 2

[0020] ​The scraper 9 will inevitably be worn by the friction with the inner wall of the stirring barrel 1 after frequent work. In order to compensate for the wear and ensure that the scraper 9 can always abut against the inner wall of the stirring barrel 1, the adjusting device 7 is provided. Specifically, the spring 13 of the adjusting device 7 is in a compressed state. Under the action of the reaction force of the spring 13, the scraper 9 on the mounting plate 8 can abut against the inner wall of the stirring barrel 1 tightly under normal circumstances. When the scraper 9 is worn due to the continuous friction with the inner wall of the stirring barrel 1, and a certain distance difference between the scraper 9 and the inner wall of the stirring barrel 1 is caused, the spring 13 originally in the compressed state will automatically elongate by a corresponding length. Under the elongation action of the spring 13, the mounting plate 8 will be pressed by the spring 13, and then the mounting plate 8 together with the connecting rod 12 will move along the guide sleeve 11 to approach the inner wall of the stirring barrel 1, and then the scraper 9 on the mounting plate 8 will also move synchronously to approach the inner wall of the stirring barrel 1, so that the scraper 9 abuts against the inner wall of the stirring barrel 1 again, compensates for the wear caused by the frequent use of the scraper 9, and then ensures that the scraper 9 always abuts against the inner wall of the stirring barrel 1, ensuring the use effect of the scraper 9.

[0021] In example three, on the basis of example two, further, the adjusting rod 10 is limited and positioned outside the stirring rod 4 by the screw rod 15, the supporting rod 16 and the limiting assembly 17 and other components, so as to ensure the compressed state of the spring 13. When it is necessary to further adjust the compression degree of the spring 13 and enhance the self-adaptive adjusting effect of the scraper 9, the limiting nut 21 on the adjusting rod 10 is first rotated to release the limitation of the screw sleeve 14, and then the adjusting rod 10 is pushed to move along the stirring rod 4 to approach the inner wall of the stirring barrel 1, and the spring 13 will be further compressed. When the compressed state of the spring 13 reaches the ideal effect, the limiting nut 21 on the screw rod 15 is rotated again to make the limiting nut 21 abut against both ends of the screw sleeve 14, so that the position of the adjusting rod 10 is limited and the compressed state of the spring 13 is maintained, thereby ensuring the use effect of the adjusting device 7, so that the scraper 9 can be self-adaptively and tightly attached to the inner wall of the stirring barrel 1 even if it is worn. The guide groove 19 is formed on the mounting sleeve 18 and is in sliding cooperation with the guide key 20 on the stirring rod 4, so as to limit the rotation of the adjusting rod 10 around the stirring rod 4, and facilitate the change of the position of the adjusting rod 10 on the stirring rod 4, thereby changing the compressed state of the spring 13.
