[0036] 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 creative work are within the scope of protection of the present invention.

[0037] In order to solve the technical problems in the prior art that feathers are easily piled together and difficult to separate, and feathers need to be distinguished in direction, please refer to Figure 1-Figure 3 , the present invention discloses the following technical problems:

[0038] A Muscovy duck black feather screening device comprises a feed screen 1, one end of which is connected to a feed device 2, the feed screen 1 is a shaking screen plate device, impurities and broken hair are separated by the feed screen 1, and the Muscovy duck positive feathers are retained, mounting plates 21 are symmetrically arranged on both sides of the feed device 2, a transmission component 3 and a lead-out component 4 are arranged on the mounting, a blower 22 and a drive component 5 are arranged on the surface of the feed device 2, a blower plate 23 is arranged in the blower 22, the drive component 5 is respectively engaged with the blower 22 and the transmission component 3, a sorting device 6 is connected to the lower end of the feed device 2 through a bracket, a first stopper 11 with staggered distribution is arranged on the feed screen 1, the feed device 2 comprises a rectangular feed trough and a conical feed trough, the rectangular feed trough and the conical feed trough are fixedly connected, and the rectangular feed trough and the conical feed trough are inclined, a second stopper 24 is arranged in the rectangular feed trough, and a conical hole 25 is opened at the lower end of the conical feed trough;

[0039] Specifically, when the feed screen 1 is working, the feed screen 1 drives the feather to shake and move, and the feather is broken up by the shaking, so that the feather is dispersed. When the feather contacts the first blocking rod 11, the feather moving laterally cannot pass through, but the feather moving longitudinally can pass through. The first blocking rod 11 plays a role in adjusting the direction of the feather. When one end of the feather shaft moves downward, it can pass through the first blocking rod 11 and is finally stuck in the conical hole 25. The feather shaft passes through the conical hole 25. When one end of the feather vane moves downward, due to the heavy weight of the feather shaft, it falls downward faster, causing the feather to tilt. The feather is blocked by the second blocking rod 24 and stays on the second blocking rod 24.

[0040] In order to solve the technical problem that the feathers cannot pass through the feeding device 2 completely vertically, please refer to Figure 3-Figure 5 , the present invention proposes the following technical solutions:

[0041] Extension rods are provided at both ends of the blowing plate 23, and the extension rods are movably connected to the blowing tube 22 through bearings, and a first gear 231 is provided on the extension rod, and the first gear 231 is intermittently meshed with the incomplete gear 53, and an inclined air guide plate 221 is provided at a position of the blowing tube 22 close to the second material blocking rod 24;

[0042] Specifically, an air inlet hole is provided on one side of the second stopper rod 24, and the air guide plate 221 guides the wind force generated by the blowing plate 23 to the bottom of the second stopper rod 24, so that the wind force blows upward from the bottom of the second stopper rod 24, and the feathers blocked by the second stopper rod 24 can be blown upward. When the incomplete gear 53 is working, it intermittently drives the first gear 231 to rotate, and the blowing plate 23 intermittently blows air into the feeding device 2 to blow the feathers blocked by the second stopper rod 24 upward. When no air is blown, the feathers move downward under the action of gravity, and when the blown feathers fall, the feathers close to the feather shaft end fall faster, ensuring that the feather shaft passes downward through the second stopper rod 24.

[0043] In order to solve the problem that feathers cannot be screened one by one in the prior art, please refer to Figure 4-Figure 7 , the present invention proposes the following technical solutions:

[0044] The driving assembly 5 includes a driving motor 51, a synchronous shaft 52, an incomplete gear 53 and a first bevel gear 54. The output end of the driving motor 51 is meshed with the synchronous shaft 52 through a gear. The synchronous shaft 52 is connected to the side wall of the feeding device 2 through a bearing seat near the end. The incomplete gear 53 is symmetrically arranged on the synchronous shaft 52 inside the bearing seat. The incomplete gear 53 is meshed with one end of the blowing plate 23. The first bevel gear 54 is symmetrically arranged on the synchronous shaft 52 outside the bearing seat.

[0045] The transmission assembly 3 includes a transmission shaft 31, a second bevel gear 32, a first synchronous wheel 33 and a synchronous belt 34. The transmission shaft 31 is connected to the side wall of the feeding device 2 through a bearing seat. The upper end of the transmission shaft 31 is provided with a second bevel gear 32, and the second bevel gear 32 is meshed with the first bevel gear 54. The lower end of the transmission shaft 31 is provided with a first synchronous wheel 33, and the first synchronous wheel 33 is sleeved with a synchronous belt 34.

[0046] The export assembly 4 includes a rotating shaft 41, a second synchronous wheel 42 and a clamping plate 43. The rotating shaft 41 passes through the mounting plate 21, and the rotating shaft 41 is movably connected to the mounting plate 21. The rotating shaft 41 is arranged below the mounting plate 21 and is provided with a second synchronous wheel 42. The second synchronous wheel 42 is sleeved with the synchronous belt 34. The rotating shaft 41 is arranged above the mounting plate 21 and is sleeved with the clamping plate 43. The rotating shaft 41 includes a rectangular column 411 and a shaft body 412. The shaft body 412 passes through the mounting plate 21. One end of the shaft body 412 is connected to the second synchronous wheel 42. The shaft body 41 2 is fixed to the rectangular column 411, the rectangular column 411 is sleeved with the clamping plate 43, and the two ends of the rectangular column 411 are provided with limit blocks, the clamping plate 43 is provided with a sliding groove 431, the sliding groove 431 is engaged with the rectangular column 411, and a support spring 432 is symmetrically arranged in the sliding groove 431, one end of the support spring 432 is fixedly connected to the side wall of the rectangular column 411, both ends of the clamping plate 43 are curved surface structures, and the end of the clamping plate 43 is provided with an anti-skid rubber pad, so that the problem of feathers falling will not occur during the clamping process of the clamping plate 43 on the feather shaft;

[0047] Specifically, the shaft body 412 is driven to rotate by the second synchronous wheel 42, and the shaft body 412 drives the rectangular column 411 to rotate. The rectangular column 411 cannot rotate in the clamping plate 43, so the rectangular column 411 drives the clamping plate 43 to rotate synchronously. During the rotation process, one end of the clamping plate 43 approaches each other to clamp the feather shaft of the feather. At the same time, the clamped feather shaft is dragged out of the tapered hole 25, and the corresponding feather is taken out as a whole. As the rotation angle changes, the feather shaft is released by the clamping plate 43, and the feather falls on the movable plate 61. The clamping plate 43 does not It can rotate around the rectangular column 411, but can rotate with the rectangular column 411. At the same time, when the clamping plate 43 rotates to one end and approaches, one end of the clamping plate 43 will squeeze each other. At this time, the support spring 432 at the squeezed end contracts, and the clamping plate 43 moves along the rectangular column 411. The support spring 432 at the other end is stretched until the squeezing force at one end of the clamping plate 43 disappears, the feather falls, and the support spring 432 is reset. Through the displacement of the clamping plate 43, the clamping time of the feather shaft can be extended, thereby driving the feather to move out of the feeding device 2.

[0048] In order to solve the technical problem of artificially screening feather colors in the prior art, please refer to Figure 1 , Figure 2 and Figure 7 , the present invention proposes the following technical solutions:

[0049] The sorting device 6 includes a movable plate 61, a rotating motor 62 and a CCD sensor 63. The movable plate 61 is arranged below the feeding device 2 through a bracket. One end of the movable plate 61 is meshed with the rotating motor 62 through a gear. The rotating motor 62 is electrically connected to the CCD sensor 63. Both ends of the movable plate 61 are connected to the bracket through a rotating shaft. A second gear 611 is arranged on the rotating shaft at one end of the movable plate 61. A third gear 621 is arranged at one end of the rotating motor 62. The third gear 621 is meshed with the second gear 611.

[0050] Specifically, the CCD sensor 63 captures a position near the conical hole 25. When the feather is pulled out for a certain distance, the CCD sensor 63 can determine whether the feather is a black feather. The rotating motor 62 drives the third gear 621 to rotate in different directions, and controls the second gear 611 to drive the movable plate 61 to tilt in different directions. The black feathers are screened out by the different tilt directions of the movable plate 61. The CCD sensor 63 determines that the feather is a black feather, and controls the rotating motor 62 to drive the movable plate 61 to tilt in the direction of the device for storing black feathers. When the black feather falls, it can slide into the device for storing black feathers under the guidance of the movable plate 61.

[0051] In order to better demonstrate the use process of the Muscovy duck black feather screening device, this embodiment now proposes a method for using the Muscovy duck black feather screening device, including the following steps:

[0052] Step 1: The feed screen 1 drives the feathers to shake and move, and the feathers are scattered under the shaking, so that the feathers are dispersed and enter the feed device 2 one by one or in small quantities;

[0053] Step 2: Under the action of gravity, the feather shaft moves downward, and the feather with the feather shaft downward passes through the feeding device 2 first, and the feather shaft extends out of the feeding device 2. The feather with the feather shaft upward tilts during the downward movement and is intercepted by the second stopper 24;

[0054] Step 3: The feather shaft extends out of the feeding device 2, and the driving motor 51 drives the synchronous shaft 52 to rotate, and the first bevel gear 54, the second bevel gear 32, the first synchronous wheel 33 of the transmission shaft 31, the synchronous belt 34 and the second synchronous wheel 42 drive the rotating shaft 41 to rotate, and the clamping plate 43 rotates to clamp and fix one end of the feather shaft, and pull the feather out of the feeding device 2 as a whole;

[0055] Step 4: After the feather is pulled out for a certain distance, the CCD sensor 63 determines whether the feather is a black feather. The CCD sensor 63 controls the rotary motor 62 to drive the third gear 621 to rotate in different directions according to the color of the feather, and controls the second gear 611 to drive the movable plate 61 to tilt in different directions. The black feathers are screened out by the different tilt directions of the movable plate 61.

[0056] Step 5: During the screening process, the driving motor 51 simultaneously drives the incomplete gear 53 on the synchronous shaft 52 to rotate, and intermittently drives the first gear 231 to rotate. The blowing plate 23 intermittently blows air into the feeding device 2 to blow the feathers blocked by the second blocking rod 24 upward. When no air is blown, the feathers move downward under the action of gravity, and when the blown feathers fall, the feathers close to the feather shaft end fall faster, ensuring that the feather shaft passes downward through the second blocking rod 24.

[0057] In summary: the black feather screening device and method of the Muscovy duck are provided with a feed screen 1 and a feed device 2, which separates the accumulated feathers through the double blocking of the first blocking rod 11 and the second blocking rod 24, changes the moving direction of the feathers, ensures the vertical movement of the feathers, and automatically completes the feeding step; an inclined air guide plate 221 is provided at a position of the blower 22 close to the second blocking rod 24, and the air guide plate 221 guides the wind force generated by the blower plate 23 to the bottom of the second blocking rod 24, so that the wind force blows upward from the bottom of the second blocking rod 24, and the feathers blocked by the second blocking rod 24 can be blown upward, and the feathers close to one end of the feather shaft are moved downward. The falling speed is faster, ensuring that the feather shaft passes downward through the second blocking rod 24; when the transmission component 3 drives the air guide plate 221 to rotate, it can also drive the export component 4 to work at the same time, and the rotating shaft 41 drives the clamping plate 43 to clamp the feather shaft leaking out of the feeding device 2, and pulls out the feathers one by one, and screens them by color one by one to prevent omission; the sorting device 6 uses a CCD sensor 63 for color discrimination, and then the rotating motor 62 drives the second gear 611 to drive the movable plate 61 to tilt in different directions. The black feathers are screened out by the different tilt directions of the movable plate 61, which saves manpower and has a high degree of automation.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A method for using the Muscovy duck black feather screening device according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1: The feed screen (1) drives the feathers to vibrate and move, and the feathers are broken up by the vibration, so that the feathers are dispersed and enter the feed device (2) one by one or in small quantities; S2: Under the action of gravity, the feather shaft moves downward, the feather with the feather shaft downward passes through the feeding device (2) first, and the feather shaft extends out of the feeding device (2), and the feather with the feather shaft upward tilts during the downward movement and is intercepted by the second stopper rod (24); S3: The feather shaft of the feather extending out of the feeding device (2) is driven by the driving motor (51), which drives the synchronous shaft (52) to rotate, and the first bevel gear (54), the second bevel gear (32), the transmission shaft (31), the first synchronous wheel (33), the synchronous belt (34) and the second synchronous wheel (42) are driven to drive the rotating shaft (41) to rotate, and the clamping plate (43) rotates to clamp and fix one end of the feather shaft, and the feather is pulled out of the feeding device (2) as a whole; S4: After the feather is pulled out for a certain distance, the CCD sensor (63) determines whether the feather is a black feather. The CCD sensor (63) controls the rotary motor (62) to drive the third gear (621) to rotate in different directions according to the color of the feather, and controls the second gear (611) to drive the movable plate (61) to tilt in different directions. The black feather is screened out by the different tilt directions of the movable plate (61); S5: During the screening process, the driving motor (51) simultaneously drives the incomplete gear (53) on the synchronous shaft (52) to rotate, intermittently drives the first gear (231) to rotate, and the blowing plate (23) intermittently blows air into the feeding device (2) to blow the feathers blocked by the second blocking rod (24) upwards. When no air is blown, the feathers move downwards under the action of gravity, and when the blown feathers fall, the feathers closer to the feather shaft fall faster, ensuring that the feather shaft passes downward through the second blocking rod (24).
