Detailed Implementation

[0027] like Figures 1 to 5 As shown, a variable cross-section rotary cutting scraper for chute anti-clogging includes a chute body 1. A support rod 2 is fixedly connected inside the chute body 1. A wire hole can be provided inside the support rod 2 so that the wiring can run inside the support rod 2 when powering and controlling the motor 4. Alternatively, the support rod 2 can be made circular to avoid material accumulation. A housing 3 is fixedly connected to the top of the support rod 2. A motor 4 is fixedly connected inside the housing 3. A rotating shaft 5 is fixedly connected to the output end of the motor 4. A rotary cutting blade 6 and a scraping device 7 are respectively sleeved on the outer surface of the rotating shaft 5. A plug 8 is threadedly connected to the bottom of the rotating shaft 5.

[0028] A mounting plate 101 is fixedly connected to both the upper and lower sides of the chute body 1. Several mounting holes 102 are opened around each mounting plate 101, and the mounting holes 102 are used to connect with other equipment.

[0029] The outer shell 3 is a conical hollow structure. The rotating shaft 5 is rotatably connected to the outer shell 3 through bearings and fixedly connected to the output end of the motor 4. The conical outer shell 3 can prevent falling materials from accumulating on the top of the outer shell 3 and will slide down its slope. At the same time, the material falling on the tip of the cone can also play a role in crushing.

[0030] A sleeve 501 is fixedly connected to the bottom of the rotating shaft 5, and a limiting groove 502 is provided on one side of the sleeve 501.

[0031] The rotary cutter 6 includes a first collar 601, the inner diameter of which is adapted to the diameter of the shaft 501, and the first collar 601 is sleeved on the outside of the shaft 501.

[0032] The first ring 601 is internally fixedly connected to a first limiting block 602, which is engaged with the limiting groove 502. Blades 603 are fixedly connected to both sides of the first ring 601. Through the engagement of the first ring 601 and the limiting groove 502, the second ring 701 can be limited, so that it rotates synchronously with the rotating shaft 5. By setting blades 603 on the first ring 601, the material will be broken and dispersed by the blades 603 during the falling process, avoiding clumping or accumulation, and making the feeding smoother. Variable cross section means that the blades 603 are curved and the cross-sectional area decreases from the outside to the inside.

[0033] The scraping device 7 includes a second collar 701, the inner diameter of which is adapted to the diameter of the shaft 501, and the second collar 701 is sleeved on the outside of the shaft 501.

[0034] The second ring 701 is internally fixedly connected to a second limiting block 702. The second limiting block 702 is engaged with the limiting groove 502. Through the engagement of the second limiting block 702 and the limiting groove 502, the second ring 701 can be limited, so that it rotates synchronously with the rotating shaft 5.

[0035] A connecting rod 703 is fixedly connected to each side of the second ring 701. A scraper 704 is fixedly connected to one side of each connecting rod 703. One side of the scraper 704 is in contact with the inner surface of the chute body 1. By setting the scraper 704, the scraper 704 can be driven to scrape the inner wall of the chute body 1 during rotation, so as to avoid the chute body 1 being blocked by loose materials and affecting the normal conveying of the chute.

[0036] A threaded hole 503 is provided at the bottom of the sleeve shaft 501. A bolt 801 is fixedly connected to one side of the plug 8. The bolt 801 is threaded into the inside of the threaded hole 503. The first collar 601 and the second collar 701 can be limited and fixed by the threaded connection between the plug 8 and the sleeve shaft 501 to prevent them from sliding up and down.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] The conical outer shell 3 can prevent falling materials from accumulating at the top of the shell 3, allowing them to slide down its slope. At the same time, the material falling on the cone tip can also play a role in crushing. By setting blades 603 on the first ring 601, the material will be crushed and dispersed by the blades 603 during the falling process, avoiding clumping or accumulation and making the material discharge smoother. By setting scraper 704, the scraper 704 can be driven to scrape the inner wall of the chute body 1 during rotation, preventing the inside of the chute body 1 from being blocked by loose materials, which would affect the normal conveying of the chute.
