[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present invention. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6A spiral feeding device for food machinery includes an outer cylinder 1, the outer side of the outer cylinder 1 is rotatably connected to a bracket 2, the top of the outer cylinder 1 is connected to a feeding port 3, a feeding mechanism is provided in the outer cylinder 1, a crushing mechanism 4 is provided in the feeding port 3, a maintenance mechanism 5 is provided inside the crushing mechanism 4, and a mounting mechanism 6 is provided on the maintenance mechanism 5; the crushing mechanism 4 includes a protective box 41 fixed to one side of the feeding port 3, the gear is protected by the protective box 41 to prevent its surface from being contaminated by dust, a first motor 42 is provided on one side of the protective box 41, and the output end of the first motor 42 passes through one side of the protective box 41 and is fixedly connected to a driving wheel 4 3. The outer side of the driving wheel 43 is meshedly connected with the driven wheel 44. The inner rings of the driving wheel 43 and the driven wheel 44 are fixedly connected with a connecting shaft 45. One end of the connecting shaft 45 passes through the protective box 41 and is fixedly connected to a crushing roller 46 on one side of the feed port 3; the maintenance mechanism 5 includes an oil filling pipe 51 connected to the top of the protective box 41, a plug is clamped on the inner wall of the oil filling pipe 51, and the bottom end of the oil filling pipe 51 is connected to a diversion pipe 52. A connecting plate 53 is clamped on one side of the protective box 41, and a brush 54 is provided inside the connecting plate 53. The interior of the protective box 41 is slidably connected to an oil receiving box 55, and a filter screen 56 is clamped on the inner wall of the oil receiving box 55.

[0026] It should be noted that: the first motor 42 on one side of the protective box 41 is started to drive the driving wheel 43 to rotate, and when the driving wheel 43 rotates, the driven wheel 44 is driven to rotate, so that the connecting shaft 45 drives the crushing roller 46 to rotate, and the material is poured into the feed port 3. The two sets of crushing rollers 46 can crush the block material to avoid the accumulation of the material in the feed port 3 and cause blockage. The crushed material enters the outer cylinder 1, and then the feeding mechanism is started to drive the material in the outer cylinder 1 to move and transport it to the designated position;

[0027] When the gears need maintenance, the plug in the oil filling pipe 51 is removed, and then the lubricating oil is poured into the oil filling pipe 51. The lubricating oil flows to the brush 54 through the diverter pipe 52. The gears come into contact with the brush 54 during rotation, and the lubricating oil is applied to the gears through the brush 54, which can reduce the wear between the gears. The lubricating oil dripping from the gears will fall into the oil collecting box 55 for collection, avoiding waste of lubricating oil. Impurities in the lubricating oil can be filtered through the filter 56, and the brush 54 can be easily removed for replacement through the connecting plate 53.

[0028] In the specific implementation process, Figure 1 and Figure 2 As shown, the feeding mechanism includes a second motor 7 fixed to one end of the outer cylinder 1, the output end of the second motor 7 is fixedly connected to a connecting rod 8, a paddle 9 is provided on the outside of the connecting rod 8, and a support rod 10 is fixedly connected to the inner wall of the outer cylinder 1. One end of the connecting rod 8 is rotatably connected to one side of the support rod 10 through a bearing seat, and one end of the connecting rod 8 is rotatably connected to one side of the support rod 10 through a bearing seat.

[0029] It should be noted that: starting the second motor 7 causes the connecting rod 8 to drive the paddle 9 to rotate. Through the rotation of the paddle 9, the material can be moved and thus transported to the specified position. The support rod 10 provides auxiliary support, which allows the connecting rod 8 to maintain stability during rotation.

[0030] refer to Figure 4 and Figure 5 As shown, the mounting mechanism 6 includes a positioning rod 61 sliding on the inner wall of the connecting plate 53, one end of the positioning rod 61 is fixedly connected to a fixing block 62, a spring 63 is provided on the outer side of the positioning rod 61, one side of the fixing block 62 is fixedly connected to a pull ring 64, a positioning hole 65 is provided on the inner wall of the brush 54, one end of the spring 63 is fixedly connected to one side of the connecting plate 53, and the other end of the spring 63 is fixedly connected to one side of the fixing block 62.

[0031] It should be noted that: the connecting plate 53 is removed from the protective box 41, and then the pull ring 64 is pulled to make the fixing block 62 drive the positioning rod 61 to move so that it is separated from the positioning hole 65. At this time, the spring 63 is in a stretched state, thereby releasing the restriction on the brush 54, making it easy to remove the brush 54 from the connecting plate 53, and to replace or clean it. Then the brush 54 is installed in the connecting plate 53, and the pull ring 64 is loosened. The rebound force of the spring 63 can make the positioning rod 61 inserted into the positioning hole 65, thereby completing the fixation of the brush 54, and the operation is convenient.

[0032] refer to Figure 1 and Figure 6 As shown, a positioning block 11 is fixedly connected to the bottom of the outer cylinder 1, and a connecting column 12 is rotatably connected to the outside of the positioning block 11 through a rotating shaft. A support column 13 is slidably connected to the outside of the connecting column 12, and a limiting block 14 is fixedly connected to the outside of the connecting column 12. A third motor 15 is provided at the bottom of the inner cavity of the support column 13, and a screw rod 16 is fixedly connected to the output end of the third motor 15.

[0033] The outer side of the limiting block 14 is slidably connected to the inner wall of the supporting column 13 , and the outer side of the screw rod 16 is threadedly connected to the inner wall of the connecting column 12 .

[0034] The bottom of the support column 13 is fixedly connected to a limit plate 17 . The inner wall of the limit plate 17 is provided with a mounting hole. The limit plate 17 is fixed to the ground through the mounting hole, thereby stabilizing the support column 13 .

[0035] It should be noted that: starting the third motor 15 in the support column 13 drives the screw rod 16 to rotate, and the limit block 14 can prevent the connecting column 12 from rotating with the screw rod 16, so that it drives the positioning block 11 to rise and fall, and drives one end of the outer cylinder 1 to rise and fall, thereby adjusting the angle of the outer cylinder 1.

[0036] The working principle of the spiral feeding device for food machinery provided by the utility model is as follows:

[0037] During use, the crushing mechanism 4 is started, and then the material is poured into the feed port 3. The block material can be crushed by the crushing mechanism 4 to avoid blockage inside the feed port 3. The gears are protected by the protective box 41 to prevent dust from contaminating their surfaces. The gears are then maintained by the maintenance mechanism 5 to reduce wear between them, extend the service life of the gears, and prevent lubricating oil from dripping into the material.
