DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-4 The drying device for extracting Forsythia suspensa leaves shown in the figure comprises a support frame 1, a heating roller 2 is arranged on the top of the support frame 1, a power unit 3 for driving the heating roller 2 to rotate is arranged on the top of the support frame 1 and on the side of the heating roller 2, a discharge hopper 4 is arranged at the bottom of one end of the heating roller 2, and a feed hopper 5 is arranged at the top of the other end of the heating roller 2;

[0019] It should be noted that the overall reference model HZG rotary drum dryer consisting of the support frame 1, heating drum 2, power unit 3 and discharge hopper 4 works according to the principle of operation;

[0020] The inner wall of the feed hopper 5 is provided with a protective member;

[0021] Specifically, the protective component includes a grid frame 6, the inner wall of the grid frame 6 is provided with a protective net 7, and the inner wall of the feed hopper 5 and the bottom of the grid frame 6 are symmetrically provided with a locking part for fixing the grid frame 6;

[0022] It should be noted that the material of the protective net 7 is stainless steel, the aperture of the protective net 7 is 5 cm, and it is welded and fixed to the inner side of the grid frame 6. The inner wall of the feed hopper 5 is provided with an annular rectangular groove for placing the grid frame 6;

[0023] Specifically, the locking part includes a plug post 9 arranged on the inner wall of the feed hopper 5, the top of the plug post 9 is inserted and connected to the bottom of the grid frame 6, and a movable rod 11 is inserted and connected to the outer side of the grid frame 6, and one end of the movable rod 11 is fixedly connected to an insert block 10 for inserting into the side of the plug post 9, and a compression spring 12 is sleeved on the outer side of the movable rod 11;

[0024] It should be noted that the column 9 is welded to the inner wall of the annular rectangular groove, a cylindrical hole for the column 9 to be inserted is provided at the bottom of the truss frame 6, a movable groove 601 is provided on the side of the truss frame 6, the movable groove 601 is connected to the cylindrical hole, the movable rod 11 moves in the movable groove 601, the plug block 10 is welded and fixed to the end of the movable rod 11, the compression spring 12 is arranged inside the movable groove 601, and an annular groove 901 for the plug block 10 to be inserted is provided on the side of the column 9.

[0025] Specifically, when the plug post 9 is inserted into the cylindrical hole, the compression spring 12 is squeezed by the plug block 10 and deformed. As the plug post 9 continues to be inserted, the compression spring 12 drives the plug block 10 to be inserted into the annular groove 901, thereby limiting and fixing the plug post 9. The top inner wall and the bottom inner wall of the annular groove 901 are both inclined curved surfaces, which facilitates the insertion and removal of the plug block 10 from the annular groove 901.

[0026] The other end of the movable rod 11 is fixedly connected to the limit plate 111, and the connection method is welding. The top of the grid frame 6 is fixedly connected with an isolation plate 13 for shielding the limit plate 111. Since a space for the movable rod 11 to move is reserved, a movable gap is left between the limit plate 111 and the inner wall of the annular rectangular groove. In order to prevent debris from falling into the gap and affecting the movement of the movable rod 11, the isolation plate 13 welded to the grid frame 6 plays a role in closing the gap.

[0027] A handle 8 for lifting the grid frame 6 is fixedly connected to the top of the grid frame 6. The handle 8 is made of aluminum alloy and is fixed to the grid frame 6 by welding. The user can pull the handle 8 to separate the grid frame 6 from the plug post 9.

[0028] During actual use, a protective component is provided on the inner wall of the feed hopper 5 at the top of the heating drum 2. After the user adds the Forsythia leaves into the heating drum 2, the grid frame 6 with the protective net 7 in the protective component is placed into the inner wall of the feed hopper 5, the plug post 9 is inserted into the cylindrical hole at the bottom of the grid frame 6, and the compression spring 12 drives the plug block 10 to be inserted into the annular groove 901 on the side of the plug post 9, thereby fixing the grid frame 6. During the heating and tumbling process of the heating drum 2, the protective net 7 in the middle of the grid frame 6 can prevent the staff from accidentally falling into the feed hopper 5 during operation, and the protective net 7 can also prevent foreign objects with a size larger than the aperture of the protective net 7 from entering the heating drum 2 from the feed hopper 5, thereby avoiding foreign objects from contaminating the Forsythia leaves.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
