[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0035] This embodiment describes the structure and working principle of the spiral feeder, specifically:

[0036] like Figure 1 As shown, the present application provides a screw feeder, comprising a support mechanism 1, the support mechanism 1 having a base 11, and a plurality of rollers 12 are arranged at the lower end of the base 11, so that the base 11 can be conveniently moved in a working area;

[0037] A conveying mechanism 2 is installed on the base 11. The conveying mechanism 2 includes a cylinder 23 fixedly installed on the base 11. The height of the cylinder 23 gradually increases as it moves away from the base 11, so as to facilitate conveying materials to a higher position.

[0038] A feeding bin 21 for feeding materials is arranged at the bottom of the cylinder 23, and a discharging bin 22 is arranged at the top of the cylinder 23. In order to transport the material from the feeding bin 21 to the discharging bin 22, Figure 2-Figure 3 As shown, a driving assembly 24 is installed on the base 11, and the driving assembly 24 includes a support plate 241 fixedly installed on the base 11, a first motor 242 is fixedly installed on the support plate 241, and a driving wheel 243 is fixedly installed on the output end of the first motor 242, and the driving wheel 243 is suitable for rotating under the drive of the first motor 242;

[0039] At the same time, an auger 25 is rotatably installed inside the cylinder 23, and the auger 25 passes through the bottom end of the cylinder 23, and is fixedly installed with a driven wheel 244. A belt 245 is installed between the driven wheel 244 and the driving wheel 243, so that the driven wheel 244 can rotate synchronously with the driving wheel 243, and drive the auger 25 to rotate inside the cylinder 23, thereby transporting the material from the inlet bin 21 of the cylinder 23 to the outlet bin 22, so as to realize the transportation of the material.

[0040] During the material conveying process of the conveying mechanism 2, the material may remain on the inner wall of the cylinder 23, and as the material continues to accumulate, the material will agglomerate and adhere to the inner wall of the cylinder 23. If it is not cleaned in time, the agglomeration in multiple places for a long time will cause the conveying mechanism 2 to deliver the material poorly, and in severe cases, it will cause blockage.

[0041] In order to solve the above problems, Figure 1 As shown, this embodiment provides a clearing mechanism 3 to remove the material attached to the inner wall of the cylinder 23 in time, specifically:

[0042] like Figure 2 As shown, a plurality of groups of holes 231 are arranged on the cylinder 23 along the conveying direction of the material, and each group of holes 231 is arranged along the circumferential direction of the cylinder 23, and the holes 231 are all connected to the interior of the cylinder 23;

[0043] like Figure 4-Figure 6 As shown, a movable rod group 5 is installed in each hole 231, and the movable rod group 5 is used to clean or prevent materials from adhering to the inner wall of the cylinder 23. The movable rod group 5 includes a ring 51 fixedly installed inside the hole 231, and the ring 51 is sealed with the hole 231;

[0044] Meanwhile, a rod 52 is provided inside the ring 51, and the rod 52 is sealed and slidably installed with the ring 51. The rod 52 has a first end suitable for inserting into the cylinder 23, and a second end away from the cylinder 23, and a stopper 54 is provided at the second end. A spring 53 is fixedly provided between the stopper 54 and the ring 51, and the spring 53 is sleeved on the outer ring of the rod 52.

[0045] In the initial state, the first end of the rod 52 passes through the ring 51 and is received in the hole 231 under the action of the spring 53 to form a contracted state. When the second end of the rod 52 is compressed, the first end of the rod 52 enters the cylinder 23 to form an extended state, and removes the material attached to the hole 231. Then, the rod 52 is reset under the drive of the spring 53.

[0046] In order to drive the rod 52, Figure 4-Figure 5 and Figure 7 As shown, a slant plate 31 is fixedly mounted on the base 11, and the slant plate 31 is parallel to the axis of the cylinder 23. A second motor 32 is fixedly mounted at the bottom end of the slant plate 31, and a rotating shaft 33 is fixedly mounted at the output end of the second motor 32. At the same time, a plurality of shaft seats 34 are fixedly mounted on the slant plate 31, and the rotating shaft 33 and the shaft seats 34 are rotatably arranged, so that the rotating shaft 33 can rotate stably under the drive of the second motor 32;

[0047] At the same time, a plurality of first gears 35 are fixedly mounted on the rotating shaft 33 along the length direction, and a gear assembly 4 is arranged on the outer ring of the cylinder 23. The gear assembly 4 includes a bearing 42 mounted on the outer ring of the cylinder 23 and corresponding to the position of the first gear 35. A second gear 41 is mounted on the outer ring of the bearing 42. The second gear 41 is meshed with the first gear 35 for transmission, so that the first gear 35 can rotate synchronously with the rotating shaft 33 and drive the second gear 41 to rotate;

[0048] It should be noted that the second gear 41 and the outer ring of the bearing 42 may be connected by a fastener to prevent the second gear 41 and the bearing 42 from rotating relative to each other due to excessive meshing force when the second gear 41 is meshing.

[0049] An installation cavity (not shown in the figure) is provided on the end of the second gear 41 away from the bearing 42, and a cam 43 is fixedly installed in the installation cavity. A through groove is provided inside the cam 43, and the through groove is composed of a concave arc 431 and a convex arc 432 connected end to end in sequence, so that the through groove forms an arc track with a continuously alternating diameter. At the same time, the cam 43 is arranged at a position corresponding to the movable rod group 5, and any point on the arc track can contact the rod 52. Specifically:

[0050] When the rod 52 is in a retracted state, the stopper 54 contacts the concave arc 431, and when the rod 52 is in an extended state, the stopper 54 contacts the convex arc 432. Thus, when the cam 43 rotates synchronously with the second gear 41, the concave arc 431 and the convex arc 432 contact the stopper 54 in sequence, thereby switching the rod 52 between the retracted state and the extended state, so as to actively remove the material attached to the hole 231.

[0051] In this embodiment, in order to make the switching of the stopper 54 between the concave arc 431 and the convex arc 432 smoother, a circular arc portion 55 is provided on the stopper 54 , and the circular arc portion 55 is suitable for making smooth contact with the concave arc 431 and the convex arc 432 .

[0052] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
