The processed medicinal materials and decoction pieces have the effect of promoting blood circulation and removing blood stasis. They are traditional Chinese medicines with a long history of use. Therefore, the development of leech farming has a good market prospect and economic benefits. Leech farming requires feeding. According to a Chinese patent with application publication number CN221843505U, a leech farming feeding table is disclosed. Through the above structure, it does not need to be cleaned frequently, and the impurities in the feed can be automatically screened out after feeding, which reduces the pollution of water quality caused by impurity residues, effectively reduces the workload of staff, and improves work efficiency. It is not affected by the environment, is not restricted by other devices, and does not need to be installed. The above-mentioned leech breeding feeding platform has the problem of being unable to accurately control the feed feeding amount during the feed feeding process.

[0022] Specifically, after the feed is transported upward to the position of the feeding square tube 203 by the rotating spiral conveyor sheet 205, it is discharged to the inside of the feeding roar 303 through the feeding square tube 203 and enters the inside of the throwing shell 302. At the same time, the third driven wheel 3014 rotates through the connection with the third power shaft 3013 to drive the speed regulating wheel 3015 to rotate, and the rotation of the speed regulating wheel 3015 further drives the speed regulating rod 3016, the first swing arm 3017, and the first slide pin 3018. The gear 3019 rotates together with the gear 3019, and due to the internal meshing of the gear 3019 and the inner gear ring 3021, the gear 3019 rotates together with the speed regulating wheel 3015, thereby driving the speed regulating rod 3016 to rotate inside the speed regulating wheel 3015, and driving the No. 1 swing arm 3017 and the No. 1 sliding pin 3018 to rotate together, driving the dial 3011 to rotate, and driving the No. 2 driving wheel 309 to rotate through the connection of the No. 2 driving shaft 308. It should be noted that, since the No. 1 sliding pin 3018 also rotates axially along the speed regulating rod 3016 during the rotation of the speed regulating wheel 3015, the No. 1 sliding pin 3018 also slides back and forth inside the bar groove 3012 during the process of driving the dial bar 3011 to rotate, resulting in the No. 2 driving shaft 308 The rotation speed is constantly changing, so the rotation speed of the No. 2 driving wheel 309 is also constantly changing, and further through the connection of the No. 1 belt 3010, the No. 2 driven wheel 307, the throwing shaft 305 and the throwing impeller 306 are driven to rotate at an unconstant speed, thereby throwing the feed inside the throwing shell 302, and since the rotation speed of the throwing impeller 306 is constantly changing, the strength of the throwing force of the throwing impeller 306 on the feed is constantly changing, resulting in the feed inside the throwing shell 302. The distance that the guide cover 304 is thrown is constantly changing, avoiding the feeding of the feed concentrated at a certain place in the pool, so that it is better eaten by leeches.

[0023] For further details, please refer to Figures 9 to 11 As shown: The guide part 400 includes a guide vertical shaft 401, a guide plate 402, a second swing arm 403, a second slide pin 404, a swing plate 405, a slide groove 406, a push rod 407, a fourth power shaft 408, a wheel diameter cam 409, a fourth driven wheel 4010, a linear guide rail 4011 and a linear slider 4012. The guide vertical shaft 401 is vertically rotatably mounted inside the guide cover 304, and the number of guide vertical shafts 401 is equidistant from front to back. The guide plate 402 is fixedly mounted on the outer wall of the material guide vertical shaft 401, the second swing arm 403 is fixedly mounted on the lower part of the outer wall of the material guide vertical shaft 401, the second sliding pin 404 is fixedly mounted on the bottom of the second swing arm 403 and is away from one end of the guide plate 402, the swing plate 405 is slidably arranged at the bottom of the guide cover 304 in the front-back direction, and the top of the swing plate 405 is close to one end of the second sliding pin 404. A plurality of slide grooves 406 are provided downwardly and are equidistantly distributed frontward and rearward. The inner wall of the slide groove 406 is slidably connected to the outer wall of the No. 2 slide pin 404. The push rod 407 is fixedly installed in the middle of a side of the swing plate 405 away from the No. 2 slide pin 404. The No. 4 power shaft 408 is rotatably installed inside the arch frame 301 and close to one end of the push rod 407. The wheel diameter cam 409 is fixedly installed on the outer wall of the No. 4 power shaft 408. The outer wall of the push rod 407 is slidably connected to the side wall of the road groove on the surface of the wheel diameter cam 409. The No. 4 driven wheel 4010 is fixedly installed on one end of the outer wall of the No. 4 power shaft 408. The linear guide rail 4011 is fixedly installed on the bottom of the guide cover 304 in parallel left and right. The linear slider 4012 is slidably installed on the periphery of the linear guide rail 4011, and there are two linear sliders 4012 on the periphery of the same linear guide rail 4011, and the bottom of the linear slider 4012 is fixedly connected to the top of the swing plate 405.

[0024] Specifically, the fourth driven wheel 4010 rotates to drive the fourth power shaft 408 to rotate together with the wheel diameter cam 409. The fourth power shaft 408 rotates, and the path groove on the surface generates a forward and backward reciprocating thrust on the push rod 407, so that the push rod 407 drives the swing plate 405 to swing back and forth, and the swing plate 405 can swing back and forth more stably through the sliding guide connection between the linear slider 4012 and the linear guide rail 4011. At the same time, the forward and backward swinging of the swing plate 405 also drives the slide groove 406 to swing together, thereby pushing the No. 2 sliding pin 404 to swing together, causing the No. 2 swing arm 403 to drive the guide vertical axis 401 together with the guide plate 402 to twist back and forth continuously. Due to the continuous twisting of the guide plate 402, the horizontal angle of the feed thrown out by the guide cover 304 can be continuously adjusted, so that the feed is thrown out in a fan-shaped distribution, which can increase the feeding range and is conducive to the simultaneous feeding of a large population of leeches.

[0025] For further details, please refer to Figure 4 , Figure 5 As shown: An AC motor 500 is fixedly installed inside the base 100, and a first driving wheel 501 is fixedly installed on the output shaft of the AC motor 500. The outer peripheries of the first driving wheel 501, the first driven wheel 209, the third driven wheel 3014 and the fourth driven wheel 4010 are collectively sleeved with a second belt 502.

[0026] Specifically, by starting the AC motor 500, its output shaft drives the No. 1 driving wheel 501 to rotate, further driving the No. 2 belt 502 to operate, thereby driving the No. 1 driven wheel 209, the No. 3 driven wheel 3014 and the No. 4 driven wheel 4010, so that the feeding part 200, the throwing part 300 and the guide part 400 can operate in a coordinated manner as a whole, realizing the feeding, throwing and feeding angle adjustment of the feed, so that the feed can be fed more widely.

[0027] When the feeding mechanism for leech breeding in this scheme is working, the feeding mechanism is placed at the edge of the breeding pool. The four foot cups 600 support the feeding mechanism to ensure the stability of the feeding mechanism, so that the feeding mechanism can be better used. The feed is put into the feed storage tank 202 for storage, and the sealing cover on the top of the feed storage tank 202 is closed on the top of the feed storage tank 202 to prevent the feed inside the feed storage tank 202 from falling into dust. By starting the AC motor 500, its output shaft drives the No. 1 driving wheel 501 to rotate, further driving the No. 2 belt 502 to operate, thereby driving the No. 1 driven wheel 209, the No. 3 driven wheel 3014 and the No. 4 driven wheel 4010. The No. 1 driving shaft 208 is driven to rotate by the No. 2 driving wheel 309, and the No. 1 driving shaft 208 is driven to rotate by the worm 207, which in turn drives the worm wheel 206, the feeding vertical shaft 204 and the spiral conveying piece 205 to rotate, and the feed inside the feed storage tank 202 is transported upward through the rotating spiral conveying piece 205, and the feed is transported to the feeding side. After the material is positioned at the position of the tube 203, it is discharged to the inside of the feeding roar 303 through the feeding square tube 203 and enters the inside of the ejection shell 302. At the same time, the third driven wheel 3014 rotates and drives the speed regulating wheel 3015 to rotate through the connection of the third power shaft 3013. The rotation of the speed regulating wheel 3015 further drives the speed regulating rod 3016, the first swing arm 3017, the first sliding pin 3018 and the gear 3019 to rotate together. Due to the internal meshing action of the gear 3019 and the inner gear ring 3021, the gear 3019 rotates together with the rotation of the speed regulating wheel 3015, thereby driving the speed regulating wheel 3015 to rotate. The speed lever 3016 rotates inside the speed regulating wheel 3015, and drives the No. 1 swing arm 3017 and the No. 1 sliding pin 3018 to rotate together, drives the No. 2 driving wheel 309 to rotate through the connection of the No. 2 driving shaft 308. It should be noted that since the No. 1 sliding pin 3018 also rotates along the axial direction of the speed regulating lever 3016 during the rotation of the speed regulating wheel 3015, the No. 1 sliding pin 3018 also slides back and forth inside the bar groove 3012 during the process of driving the No. 1 sliding pin 3018 to drive the No. 2 driving shaft 308 to rotate, the speed of the No. 2 driving shaft 308 is constantly changing. In addition, the rotation speed of the second driving wheel 309 is also constantly changing, and further through the connection of the first belt 3010, the second driven wheel 307, the throwing shaft 305 and the throwing impeller 306 are driven to rotate at an unconstant speed, so as to throw the feed inside the throwing shell 302. Since the rotation speed of the throwing impeller 306 is constantly changing, the strength of the throwing force of the throwing impeller 306 on the feed is constantly changing, resulting in the distance that the feed inside the throwing shell 302 is thrown from the guide cover 304 constantly changing, thereby avoiding the feeding of the feed concentrated in a certain place in the pool, so that it is better eaten by leeches; At the same time, the rotation of the fourth driven wheel 4010 drives the fourth power shaft 408 together with the wheel diameter cam 409 to rotate. The fourth power shaft 408 rotates, and the path groove on the surface generates a reciprocating thrust to the push rod 407, so that the push rod 407 drives the swing plate 405 to swing back and forth, and the swing plate 405 can swing back and forth more stably through the sliding guide connection between the linear slider 4012 and the linear guide rail 4011. At the same time, the back and forth swinging of the swing plate 405 also drives the slide groove 406 to swing together, thereby pushing the No. 2 sliding pin 404 to swing together, causing the No. 2 swing arm 403 to drive the guide vertical axis 401 together with the guide plate 402 to twist back and forth continuously. Due to the continuous twisting of the guide plate 402, the horizontal angle of the feed thrown out by the guide cover 304 can be continuously adjusted, so that the feed is thrown out in a fan-shaped distribution, which can increase the feeding range and is conducive to the simultaneous feeding of large populations of leeches.
