[0040] The scraper member includes a telescopic rod 22 fixedly connected to the top of two of the support frames 9, and a scraper plate 23 sliding on the bottom of the distribution tray 6 is installed at the bottom end of the telescopic rod 22.

The bottom end of the rectangular rod is connected to the scraper plate 23, and the plug-in rod 24 is installed on the side wall of the rectangular rod. Through the design of the scraper member, it is convenient for the scraper plate 23 to move the feed inside the distribution tray 6, thereby solving the problem of low feed falling efficiency caused by the easy accumulation of feed falling into the distribution tray 6 through the discharge port 7.

[0041] The feeding unit includes a rotating rod 37 rotatably mounted on the bottom end of the mounting tube 5, a feeding plate 38 located below the feeding tray 6 is sleeved on the rotating rod 37, one end of the rotating rod 37 is fixedly connected to a bevel gear six 39 located inside the mounting tube 5, and the two bevel gears six 39 are connected to the transmission mechanism; through the design of the feeding unit, it is convenient to release part of the feed that falls through the feeding tray 6, which can effectively change the release position of part of the feed, thereby increasing the feed release range, and effectively providing convenience for the cultivation of Chinese mitten crabs.

Since there are two discharge ports 7, some feed is located inside the sleeve tube 4 and accumulated on the top of the guide trough 27, and then through the rotation of the push plate 32, it is convenient to slide on the top of the guide trough 27, so that the push plate 32 pushes the feed at the bottom of the sleeve tube 4 to be discharged to the discharge port 7, effectively accelerating the discharge speed of the feed.

[0044] The action mechanism includes a mounting shaft 51 rotatably mounted on the inner wall of the support ring 11, a connecting seat 43 connected to the linkage rod 34 is mounted on the mounting shaft 51, the connecting seat 43 is an L-shaped structure, a bevel gear 7 42 meshing with the bevel gear 4 35 is fixedly sleeved on the mounting shaft 51, an impeller 44 is symmetrically sleeved on the mounting shaft 51, a winding wheel 45 is fixedly sleeved at the middle position of the mounting shaft 51, a winding rope 46 is wound around the winding wheel 45, a through hole 47 is opened on one of the support rods 10, two clamping wheels 48 are installed inside the through hole 47, and one end of the winding rope 46 extends to the two clamping wheels 48 The two clamping wheels 48 are in rolling contact with the winding rope 46, and the other two support rods 10 are provided with a balancing piece. It should be noted here that one end of the winding rope 46 is detachably mounted on a fixed pile on the shore where the Chinese mitten crab is cultured; through the design of the action mechanism, it is convenient for the feeding device to move in the pond, so as to realize mobile feeding of feed, effectively increase the feed delivery range, and at the same time, this design avoids manual throwing of feed, effectively reduces labor input, solves the problem of Chinese mitten crabs competing for feed due to the concentration of feed falling, thereby effectively realizing the protection of Chinese mitten crabs during the breeding process.

[0045] The implementation principle of a quantitative feeding device for Chinese mitten crab breeding feed in the embodiment of the present application is:

[0046] After the staff inflates the inflatable ring 12, they place the feeding device in the pond. Due to the effect of the inflatable ring 12, the feeding device floats on the water surface. Then, one end of the reel 46 is detachably fixed to a fixed pile on the shore. Then, the staff weighs the feed quantitatively and places the weighed quantitative feed in the feeding seat 1. Then, the feed falls onto the guide trough 27 through the diversion effect of the guide plate 52, and then part of the feed falls into the distribution plate 6 through the discharge port 7.

[0047] At the same time, the motor 13 is started, and the motor 13 drives the bevel gear 14 to rotate. Through the meshing connection relationship between the bevel gear 14 and the bevel gear 2 15 and the bevel gear 3 28 respectively, the bevel gear 2 15 and the bevel gear 3 28 will rotate in the opposite direction. The bevel gear 2 15 drives the rotating cylinder 3, the sleeve pipe 4, the installation cylinder 5 and the distribution plate 6 to rotate synchronously. Through the connection relationship between the stabilizing groove 40 and the stabilizing block 41, the delivery tube 2 drives the transmission cylinder 29, the transmission rod 31, the linkage cylinder 33, the linkage rod 34 and the bevel gear 4 35 to rotate in the opposite direction synchronously. The transmission rod 31 drives the push plate 32 to rotate at the top of the guide platform 26, so that the push plate 32 can push the feed accumulated inside the sleeve pipe 4 to move to the discharge port 7 to realize feed discharge, so that the feed completely falls into the inside of the distribution plate 6, effectively avoiding feed waste;

[0048] Because the scraper plate 23 is fixed and its bottom end is in sliding contact with the distribution plate 6, the scraper plate 23 will be able to move the feed inside it during the rotation of the distribution plate 6, effectively avoiding feed accumulation and facilitating feed dispersion, which can accelerate the feed to fall through the holes on the distribution plate 6. At the same time, because the support tube 8 is fixed, the moving block 19 will be driven to rotate synchronously during the rotation of the distribution plate 6, and then the moving block 19 will slide inside the inclined groove 21, which is convenient for realizing the upward movement of the distribution plate 6, and then the sleeve pipe 4 will drive the slider 16 to slide inside the slide groove 17 and realize the compression of the spring 18. When the moving block 19 moves to the top of the inclined groove 21, under the reverse force of the spring 18, the moving block 19 will slide to the inside of the rectangular groove 20, which will cause the distribution plate 6 to move downward, thereby realizing the reciprocating lifting and shaking of the distribution plate 6, which is convenient for the distribution plate 6 to drive the feed to shake, effectively accelerating the feeding speed of the feed.

[0049] The rotation of the linkage cylinder 33 will drive the bevel gear 5 36 to rotate, and through the meshing connection relationship between the bevel gear 5 36 and the two bevel gears 6 39, the two bevel gears 6 39 will rotate, and the bevel gear 6 39 will drive the rotating rod 37 to rotate, and the rotating rod 37 will drive the material-diverting plate 38 to rotate, so that the material-diverting plate 38 can dig part of the feed that falls through the holes of the distribution plate 6, effectively changing the feed delivery position, thereby increasing the feeding range of the feed;

[0050] The linkage rod 34 drives the bevel gear four 35 to rotate, and through the meshing connection relationship between the bevel gear four 35 and the bevel gear seven 42, the bevel gear seven 42 drives the installation shaft 51 to rotate, and the installation shaft 51 will drive the impeller 44 to rotate in the water. At the same time, the installation shaft 51 will also drive the winding wheel 45 to rotate, and the winding wheel 45 will release the winding rope 46. Since the impeller 44 rotates in the water, the feeding device will move forward in the water, so that the device can move and feed in the pond. When the feeding is completed and the feeding device returns, the motor 13 is started to reverse, and the installation shaft 51 rotates in the opposite direction and drives the winding wheel 45 to reverse, so that the winding wheel 45 can wind up the winding rope 46, and then the feeding device will retreat and approach the fixed pile on the shore that fixes the winding rope 46, effectively completing the feed feeding operation.

[0051] Embodiment 2:

[0052] Combination Figures 1 to 4 Based on Example 1, this embodiment is further improved in that: the balancing member includes a sliding opening 49 opened on two support rods 10 arranged near the through opening 47, and a traction rope 50 is passed through the interior of the sliding opening 49. It should be noted here that both ends of the traction rope 50 can be detachably installed on the fixed piles on the shore where the Chinese mitten crab is cultured. At the same time, the balancing member can also use multiple partition nets installed in the pond to enable the feeding device to move between two adjacent partition nets.

[0053] Combination Figures 1 to 4 The difference between this embodiment and embodiment 1 is that: through the design of the traction rope 50 and the sliding mouth 49, it is convenient to move the feeding device along the direction of the traction rope 50 during the movement, and the moving trajectory of the feeding device is effectively controlled to make it move in a straight line, thereby solving the problem that the feeding device is easily affected by the wind direction and the moving trajectory is easily changed.

[0054] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
