DETAILED DESCRIPTION

[0034] The specific implementation methods of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] like Figure 1-Figure 8 As shown, an automatic adding and mixing device for chicken and duck feed comprises a top cover plate 10, a mixing tank 30 and a plurality of storage hoppers 100. A plurality of vertical legs 11 are fixedly connected to the bottom of the top cover plate 10. A first mounting seat 12 and a second mounting seat 13 are fixedly provided on the top of the top cover plate 10 in sequence from bottom to top. The mixing tank 30 is located below the top cover plate 10 and has an opening at the top. The plurality of legs 11 are arranged around the mixing tank 30. A plurality of ear plates 31 are fixedly connected to the outer peripheral side surface of the mixing tank 30 corresponding to the plurality of legs 11. The ear plates 31 are slidably connected to the corresponding legs 11 up and down. The plurality of legs 11 are respectively provided with load-bearing Spring 111, the load-bearing spring 111 pushes the ear plate 31 upward, relying on the load-bearing spring 111 to provide a lifting elastic force for the mixing tank 30, so that the mixing tank 30 can automatically rise and fall with the change of the amount of feed inside it. A soft connecting tube 40 is provided between the mixing tank 30 and the top cover plate 10. The lower port of the soft connecting tube 40 is sealed and connected to the tank mouth of the mixing tank 30, and the upper end is sealed and installed on the bottom surface of the top cover plate 10. The soft connecting tube 40 is used to fill the gap between the mixing tank 30 and the top cover plate 10 to prevent the feed in the mixing tank 30 from splashing. The force exerted by the soft connecting tube 40 on the mixing tank 30 is small, so it does not affect the lifting and lowering of the mixing tank 30.

[0036] A stirring shaft 50 is vertically rotatably connected inside the mixing tank 30. The upper end of the stirring shaft 50 extends to above the top cover plate 10 and is provided with a spline. A motor 20 is fixedly arranged on the second mounting seat 13. The power output end of the motor 20 is fixedly connected to a spline sleeve 21. The spline 51 is slidably sleeved in the spline sleeve 21. When the stirring shaft 50 follows the lifting and lowering of the mixing tank 30, the motor 20 can always drive the stirring shaft 50 to rotate. A plurality of stirring paddles 52 are fixedly connected to the circumference of the stirring shaft 50. The stirring paddles 52 are located inside the mixing tank 30 and are used to stir the mixed feed.

[0037] The spline 51 is slidably connected with a first end face ratchet 511, which rotates synchronously with the stirring shaft 50 under the drive of the spline 51. A lifting spring 512 is sleeved on the spline 51, which presses the first end face ratchet 511 upward, so that the first end face ratchet 511 has a tendency to slide upward. A limiting sleeve 513 is slidably sleeved on the spline 51, and a fastening screw 514 is threadedly connected to the limiting sleeve 513 along its radial direction. The fastening screw 514 can be screwed inward to make it press against the spline 51, so as to fix the limiting sleeve 513 on the spline. On the key 51, the limit sleeve 513 is located above the first end face ratchet 511. The sliding stroke of the first end face ratchet 511 can be changed by adjusting the height position of the limit sleeve 513 on the spline 51 up and down. The first mounting seat 12 is rotatably connected to a hollow shaft 60, and the hollow shaft 60 is coaxially sleeved on the outside of the stirring shaft 50. The two are clearance-fitted and do not interfere with each other. The lower end of the hollow shaft 60 is fixedly connected to a second end face ratchet 61. When the first end face ratchet 511 is close to the second end face ratchet 61, it can mesh with the second end face ratchet 61 for transmission, thereby driving the hollow shaft 60 to rotate.

[0038] A plurality of storage hoppers 100 are fixedly arranged on the top cover plate 10 and are arranged in a circular array around the stirring shaft 50. The lower port of the storage hopper 100 corresponds to the opening of the mixing tank 30. A cylindrical cavity 101 is arranged inside the storage hopper 100 along the radial direction of the hollow shaft 60. A discharge shaft 102 is arranged in the cylindrical cavity 101 along its axis. A plurality of blades 1021 are evenly arranged on the circumferential side of the discharge shaft 102. The plurality of blades 1021 slide with the inner wall of the cylindrical cavity 101 respectively. The space above the cylindrical cavity 101 in the storage hopper 100 is used to store raw materials. When the discharge shaft 102 does not rotate, the raw materials stored in the storage hopper 100 cannot fall due to the blocking effect of the multiple blades 1021. Only when the discharge shaft 102 rotates, the raw materials can be discharged through the gap between the blade 1021 and the inner wall of the cylindrical cavity 101 and fall into the mixing tank 30. The rotation speed of the discharge shaft 102 and the blade 1021 affects the discharge speed of the storage hopper 100.

[0039] The discharge shafts 102 on the multiple storage hoppers 100 are respectively connected to the hollow shaft 60 in transmission. Specifically, the upper end of the hollow shaft 60 is fixedly connected with a large bevel gear 62, and the first mounting seat 12 is connected to a plurality of transmission shafts 70 in radial rotation along the hollow shaft 60. The end of the transmission shaft 70 close to the hollow shaft 60 is fixedly connected with a small bevel gear 71, and the multiple small bevel gears 71 are respectively meshed with the large bevel gear 62. The plurality of transmission shafts 70 correspond to the plurality of discharge shafts 102 one by one, and a speed change transmission mechanism is provided between the two corresponding transmission shafts 70 and the discharge shaft 102. The speed change transmission mechanism includes a first cone wheel 72 fixedly connected to the other end of the transmission shaft 70 and a second cone wheel 1022 fixedly connected to the discharge shaft 102, and the rotation axes of the two are parallel, the tapers are equal, and the cone tips are in opposite directions. A guide shaft 80 and a screw rod 90 parallel to each other are provided between the first cone wheel 72 and the second cone wheel 1022, and the guide shaft 80 The first and second cone wheels 1022 are rotatably connected to each other, and the first and second cone wheels 1023 are rotatably connected to each other, and the first and second cone wheels 1024 are rotatably connected to each other, so that the first and second cone wheels 1024 can be driven to rotate by the first and second cone wheels 1025. The screw rod 90 is threadedly connected with a shift fork 92, and one end of the shift fork 92 is rotatably connected to the friction wheel 81. One end of the screw rod 90 is fixedly connected with a speed regulating hand wheel 91. The speed regulating hand wheel 91 is used to rotate the screw rod 90, which can drive the shift fork 92 and use the shift fork 92 to shift the friction wheel 81 axially, so as to adjust the position of the friction wheel 81 along the axial direction of the guide shaft 80, thereby adjusting the transmission ratio between the first and second cone wheels 72 and 1022. The corresponding speed transmission mechanism is adjusted according to the proportion of the raw materials stored in each storage hopper 100, so that a variety of raw materials can be automatically added to the mixing tank 30 according to the preset proportion.

[0040] When the device is working, the motor 20 drives the stirring shaft 50 and drives the stirring paddle 52 to rotate, and at the same time indirectly drives the feed shafts 102 in the multiple storage hoppers 100 to rotate. In the process of multiple raw materials falling from the storage hopper 100 into the mixing tank 30, they can be scattered by the rotating stirring paddle 52, which can effectively reduce the mixing time and improve the mixing efficiency. As the mixed feed in the mixing tank 30 gradually increases, the height of the mixing tank 30 and the stirring shaft 50 will gradually decrease, and the first end face ratchet 511 can slide upward relative to the stirring shaft 50 under the top pressure of the lifting spring 512 before it contacts the limit sleeve 513, so that it can keep meshing with the second end face ratchet 61 until the first end face ratchet 511 is After the face ratchet 511 abuts against the lower end of the limit sleeve 513, the first end face ratchet 511 cannot continue to slide upward relative to the stirring shaft 50, and is gradually separated from the second end face ratchet 61, and the hollow shaft 60 stops rotating, causing the discharge shafts 102 in the multiple storage hoppers 100 to stop rotating, and the raw materials in the multiple storage hoppers 100 are immediately stopped from being added to the mixing tank 30. Thereafter, the stirring shaft 50 and the stirring paddle 52 can continue to rotate to fully stir the feed in the mixing tank 30. Based on the above principle, by adjusting the height position of the limit sleeve 513 on the spline 51 up and down and changing the sliding stroke of the first end face ratchet 511, the total weight of a single batch of mixed feed can be automatically controlled.

[0041] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements all fall within the scope of the utility model to be protected.
