[0026] Please refer to Figure 1 and Figure 2 , in this embodiment, in order to better install and disassemble both ends of the material guiding cylinder 01 and facilitate the subsequent cleaning of the material guiding cylinder 01 and the feeding auger, the sealing component further includes a fixing disc 023 and a handle 024. The first sealing disc 02 is connected to one end of the material guiding cylinder 01 close to the feed hopper 011 through a screw bolt. The second sealing disc 021 is connected to one end of the material guiding cylinder 01 close to the discharge port 013 through several bolts. The driving mechanism 022 is installed outside the second sealing disc 021;

[0027] The fixing disc 023 is arranged at the end of the driving mechanism 022 away from the second sealing disc 021. The handle 024 is arranged outside the fixing disc 023. On one side of the top end of the feed hopper 011, there is a material guiding hopper 012.

[0028] When feeding is required, the material is poured onto the guiding hopper 012, slides down the slope on the guiding hopper 012 into the feeding hopper 011, and drops from the feeding hopper 011 into the guiding cylinder 01. At this time, the driving mechanism 022 is started, and the driving mechanism 022 drives the feeding auger to rotate in the guiding cylinder 01, so as to drive the material in the guiding cylinder 01 to be discharged from the discharge port 013. When subsequent cleaning of the guiding cylinder 01 or the feeding auger is required, the first sealing disc 02 and the second sealing disc 021 can be removed from both ends of the guiding cylinder 01, so as to clean its interior or the feeding auger.

[0029] Please refer to Figure 1 and Figure 2 It should be noted that, in order to facilitate the staff to remove the feeding auger for cleaning more conveniently, the adjusting rod 033 is movably inserted into one side of the top end of the support frame 041. There are several fixing jacks 035 and they are all penetrated and opened on one side of the adjusting rod 033. The adjusting rod 033 is connected and fixed to the support frame 041 through the fixing jacks 035 and the fixing plug 034.

[0030] Brake rollers 04 are installed at the four corners of the bottom end of the support frame 041. The top end of the support seat 042 is an arc surface and contacts the lower surface of the guiding cylinder 01.

[0031] The first connecting rod 031 is arranged at the top end of the adjusting rod 033. The fixing ring 03 is arranged on the outer surface of the guiding cylinder 01. The second connecting rod 032 is arranged at the top end of the first connecting rod 031 and is rotatably connected to the fixing ring 03.

[0032] When the second sealing disc 021 needs to be removed, first support the guiding cylinder 01, pull out the fixing plug 034 from the fixing jack 035, and slowly lower one end of the guiding cylinder 01 while holding it up. At the same time, make the adjusting rod 033 retract into the interior of the support frame 041. After the end of the guiding cylinder 01 provided with the driving mechanism 022 is placed flat on the support frame 041, several bolts on the second sealing disc 021 can be removed, and then hold the handle 024 to pull out the driving mechanism 022 together with the feeding auger from one end of the guiding cylinder 01 for cleaning.

[0033] Please refer to Figure 1 and Figure 3 Specifically, in order to better knock and shake off the material adhering to the inner wall of the guiding cylinder 01, the support column 05 is arranged in the middle of the top end of the support frame 041. One end of the knocking rod 052 is connected to the top end of the support column 05 through a spring hinge 051. There are two support rods 055 and they are both arranged on both sides of the support column 05 near the top end.

[0034] The guide rod 056 is arranged at a position near the top between the two support rods 055. The connecting block 053 is arranged on one side of the knocking rod 052 close to the material guiding cylinder 01. One end of the pull rope 054 is connected to the connecting block 053 and the other end bypasses the guide rod 056 and is connected to the pull ball 057.

[0035] When it is necessary to clean the powder material adhered to the inner wall of the material guiding cylinder 01, first grasp the pull ball 057 and pull the pull rope 054 to drive the knocking rod 052 to open outward with the spring hinge 051 as the axis. After opening to a certain extent, release the pull rope 054. Under the rebound of the spring hinge 051, the knocking rod 052 impacts on the outer surface of the material guiding cylinder 01, and the adhered material on the inner wall of the material guiding cylinder 01 falls off due to the vibration force generated by the impact.

[0036] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
