A plurality of guide grooves 2032 are opened on the surface of the throwing plate 203, and each of the guide grooves 2032 includes a straight groove and three adjustment grooves. All the straight grooves are connected at the feed trough 2033. When the feed trough 2033 can be connected to the outside through the straight groove, the straight groove is in an open state, otherwise it is in a closed state.

[0049] The throwing assembly 2 further includes a connecting rod 212 , which slides inside the guide hole 2031 , and the connecting rod 212 is fixedly connected below the movable block 213 .

[0050] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the throwing assembly 2 further includes a second motor 206, a primary gear 207, a secondary gear set 208, a transmission shaft 209, a positioning rack 210 and a termination gear 211, wherein:

[0051] The motor 206 is fixedly connected to the bottom of the ejection plate 203, and the output end of the motor 206 is fixedly connected to the primary gear 207, and the primary gear 207 is meshed with several secondary gear sets 208. The secondary gear set 208 is composed of several gears with different pitch circle diameters sleeved on the transmission shaft 209, and the transmission shaft 209 is connected to the ejection plate 203 bearing, and the transmission shaft 209 can rotate relative to the ejection plate 203, and each of the secondary gear sets 208 is meshed with the positioning rack 210. A boss is provided on the top of each positioning rack 210, and the boss slides in the guide hole 2031 and drives the positioning rack 210 to slide toward the center of the ejection plate 203. The positioning rack 210 coincides with one of the radii of the ejection plate 203, so that the positioning rack 210 always slides in the direction of the center of the ejection plate 203. The end of the positioning rack 210 away from the center of the ejection plate 203 is rotatably connected to a termination gear 211, and the termination gear 211 is located below the positioning rack 210.

[0052] By starting the motor 206, the output end of the motor 206 drives the primary gear 207 to rotate, and the primary gear 207 drives the positioning rack 210 to slide on the ejection plate 203 through the secondary gear set 208, and the termination gear 211 approaches the secondary gear set 208. When the termination gear 211 contacts the secondary gear set 208, the secondary gear set 208 meshes with the termination gear 211 and drives the termination gear 211 to rotate. By adjusting the secondary gear set 208, the termination gear 211 can mesh with gears with different pitch circle diameters.

[0053] like Figure 7 , Figure 8 and Fig.13 As shown, in some embodiments, the secondary gear set 208 includes a small gear 2081, a middle gear 2082, a large gear 2083 and a driven gear 2084, wherein:

[0054] There are two pinion gears 2081 in the upper and lower directions. The pinion gears 2081 are fixedly connected to the transmission shaft 209. The upper pinion gear 2081 is meshed with the positioning rack 210, and the lower pinion gear 2081 is used to mesh with the termination gear 211 and drive it to rotate; the middle gear 2082 is located below the two pinion gears 2081 and the middle gear 2082 is sleeved on the transmission shaft 209. A gear groove 1 is opened above the middle gear 2082, and the gear groove 1 is connected to the pinion gear 2081. The gear groove 1 is adapted to accommodate the small gear 2081; the large gear 2083 is located below the middle gear 2082 and the large gear 2083 is sleeved on the transmission shaft 209, and a gear groove 2 is provided above the large gear 2083, the gear groove 2 is adapted to the middle gear 2082, and the gear groove 2 is used to accommodate the middle gear 2082; the driven gear 2084 located below the large gear 2083 is fixed at the bottom of the transmission shaft 209, and the driven gear 2084 is meshed with the primary gear 207.

[0055] During the rotation of the secondary gear set 208, the middle gear 2082 is moved upward, and the gear slot 2 includes one of the small gears 2081. When the termination gear 211 contacts the secondary gear set 208, the termination gear 211 meshes with the middle gear 2082, thereby achieving a smooth transition between gear sets. Similarly, the large gear 2083 is moved upward, and the gear slot 2 includes the middle gear 2082 and one of the small gears 2081. When the termination gear 211 contacts the secondary gear set 208, the termination gear 211 meshes with the large gear 2083.

[0056] like Figure 8 As shown, in some embodiments, the transmission shaft 209 includes an electric push rod 2092, a sliding rod 2093, a fixed rod 2094 and a spring 2095, wherein:

[0057] The transmission shaft 209 is hollow inside, and connection holes 2091 are opened on both sides of the transmission shaft 209. The connection holes 2091 connect the inside and the outside of the transmission shaft 209, and the connection holes 2091 are used to adjust the secondary gear set 208. The electric push rod 2092 is located inside the transmission shaft 209, and the electric push rod 2092 includes a push rod body and a telescopic rod. The push rod body is fixedly connected to the inner wall of the transmission shaft 209, and the outside of the telescopic rod is slidably connected to the sliding rod 2093. A sliding hole is opened on the sliding rod 2093, and the telescopic rod is inside the sliding hole. Both ends of the sliding rod 2093 pass through the connecting hole 2091 and are fixedly connected to the middle gear 2082; the top of the telescopic rod is fixedly connected to the fixed rod 2094, and both ends of the fixed rod 2094 pass through the connecting hole 2091 and are fixedly connected to the large gear 2083; the top of the fixed rod 2094 is fixed to the spring 2095, and the spring 2095 is sleeved on the telescopic rod of the electric push rod 2092, and the end of the spring 2095 away from the fixed rod 2094 is fixed to the sliding rod 2093.

[0058] When it is necessary to adjust the secondary gear set 208, by starting the electric push rod 2092, the telescopic rod extends into the push rod body, and the telescopic rod drives the middle gear 2082 and the large gear 2083 to move upward synchronously through the sliding rod 2093 and the fixed rod 2094. When the middle gear 2082 includes one of the small gears 2081, the electric push rod 2092 is controlled to stop. When it is necessary to continue to adjust the secondary gear set 2088, the electric push rod 2092 is started to make the telescopic rod continue to retract into the push rod body, and the telescopic rod drives the large gear 2083 to move upward. During the movement, the middle gear 2082 does not move, and the spring 2095 is gradually compressed. When the large gear 2083 includes the middle gear 2082, the electric push rod 2092 is controlled to stop working again, and the adjustment of the secondary gear set 208 is completed.

[0059] like Figure 3 As shown, in some embodiments, the throwing assembly 2 further includes a dispersion block 214, a top plate 204 and a funnel 205, wherein the dispersion block 214 is fixedly connected to the top of the throwing plate 203, and the dispersion block 214 is located at the center of the throwing plate 203 and is used to disperse the feed. The top of the throwing plate 203 is fixedly connected to the top plate 204, and a feeding port is provided in the center of the top plate 204, and the feeding port is directly above the feeding trough 2033. The top of the top plate 204 is fixedly connected to the funnel 205, and the lower end of the funnel 205 coincides with the feeding port, ensuring that the feed is evenly distributed in the feeding trough 2033 during the feeding process, and the top of the funnel 205 is fixedly connected to the feeding assembly 3.

[0060] When throwing feed to the fish school, the motor 1 7 is started, and the motor 1 7 drives the feeding assembly 3 to rotate. The feed in the feed trough 2033 moves into the guide groove 2032 under the action of centrifugal force. Due to the obstruction of the movable block 213 in the guide groove 2032, the feed accumulates in the straight groove of the guide groove 2032. When a certain amount of feed is accumulated, the motor 2 206 is started, and the motor 206 drives the primary gear 207 and the secondary gear set 208 to rotate. The secondary gear set 208 drives the positioning rack 210 to move toward the center of the throwing plate 203. During the movement of the positioning rack 210, the movable block 213 also moves toward the center of the throwing plate 203 in the guide groove 2032. When the termination gear 211 is engaged with the secondary gear set 208, the movable block 213 moves to the adjustment groove of the guide groove 2032, opens the straight groove for stacking feed, and the feed is quickly thrown into the fish area under the action of centrifugal force.

[0061] When throwing feed to the fish school close to the device, the secondary gear set 208 is adjusted to make the terminating gear 211 mesh with the pinion 2081. Since the feed is close to the center of the throwing plate 203, the centrifugal force is small and the throwing range is relatively small.

[0062] When throwing feed to a school of fish far from the device, the secondary gear set 208 is adjusted to make the end gear 211 mesh with the middle gear 2082, thereby increasing the centrifugal force and expanding the throwing range.

[0063] When throwing feed to fish schools farther away from the device, the secondary gear set 208 is adjusted to make the termination gear 211 mesh with the large gear 2083, the centrifugal force is significantly enhanced, and the throwing range is further expanded, ensuring that the feed accurately covers fish schools in farther areas.

[0064] like Fig. 9 and Fig.10As shown, in some embodiments, the feeding component 3 includes a feeding bin 301, a feeding auger 302 and a feeding spindle 303, the feeding bin 301 is open at the top and has a discharge port at the bottom, the discharge port of the feeding bin 301 is fixedly connected to the funnel 205, the inner wall of the feeding bin 301 is provided with a sliding groove, the feeding bin 301 is slidably connected to the feeding auger 302 through the sliding groove, the feeding auger 302 is in sliding contact with the inner wall of the feeding bin 301, and the contact portion of the feeding auger 302 and the feeding bin 301 is set There is a sliding block, which slides in the sliding groove of the inner wall of the feeding bin 301. The surface of the feeding auger 302 is provided with a filter hole, and the filter hole is used to separate feeds of different sizes so that the smaller feed can reach the throwing component 2 first. The feeding auger 302 is fixedly connected to the feeding spindle 303. The interior of the feeding spindle 303 is hollow. The interior of the feeding spindle 303 is used to accommodate the adjusting component 4. The surface of the feeding spindle 303 is provided with a threaded groove 3031, and the threaded groove 3031 is spirally connected to the adjusting component 4.

[0065] When the feed is delivered to the inside of the feeding bin 301, the feeding auger 302 rotates accordingly by rotating the feeding main shaft 303. During the rotation, smaller feed first passes through the filter hole into the throwing component 2 and is then thrown by the throwing component 2 to the smaller fish that are farther away from the device. The rotation of the feeding auger 302 allows the feed to be layered in the feeding bin 301, ensuring that feeds of different particle sizes enter the throwing component 2 in sequence, so that accurate feeding is achieved, the needs of various fish schools are met, and feeding efficiency is improved.

[0066] like Fig. 9 , Fig.11 and Fig.12 As shown, in some embodiments, the adjusting component 4 includes an adjusting bin 401, an adjusting auger 402, an adjusting shaft 403 and a motor three 404, the adjusting bin 401 includes the feeding bin 301, the inner wall of the adjusting bin 401 is tightly fitted with the surface of the feeding bin 301, the adjusting bin 401 is provided with an adjusting auger 402, the adjusting auger 402 is adapted to the thread groove 3031, the adjusting auger 402 can enter the thread groove 3031, the adjusting auger 402 is fixedly connected to the adjusting shaft 403, one end of the adjusting shaft 403 is inside the feeding main shaft 303, the other end of the adjusting shaft 403 passes through the storage bin 5 and is fixedly connected to the motor three 404, and the motor three 404 is fixed on the top of the storage bin 5.

A plurality of adjusting holes are provided on the surface of the adjusting disk 8. By starting the motor 404 to drive the adjusting disk 8 to rotate, the adjusting holes are aligned or staggered with the feed delivery port, so as to achieve precise adjustment of the feed flow rate and ensure uniform feed output.

[0068] The adjusting shaft 403 is driven to rotate by starting the motor 3 404 , and the adjusting shaft 403 drives the adjusting auger 402 to rotate. The adjusting auger 402 is inside the thread groove 3031 , and the adjusting shaft 403 drives the feeding spindle 303 to rotate.

[0069] The hydraulic rod 6 is started, and the hydraulic rod 6 drives the regulating bin 401 to descend, and the motor 3 404 is started to make the regulating auger 402 completely enter the thread groove 3031. At this time, the regulating shaft 403 is inside the feeding main shaft 303, and the feeding auger 302 and the regulating auger 402 cooperate to accelerate the feed transportation. The descent of the regulating bin 401 further compresses the feeding bin 301, and enhances the fluidity of the feed.

[0070] Embodiment 1: In this embodiment, the feeding machine works, and feed throwing work is performed through the throwing component 2 to achieve efficient feeding.

[0071] Specifically, the feed is poured into the storage bin 5 through the feed inlet in advance, the motor 3 404 is started to drive the adjusting shaft 403 to rotate, the adjusting shaft 403 drives the adjusting disk 8 and the adjusting auger 402 to rotate, the feed inside the storage bin 5 enters the adjusting bin 401, and the adjusting auger 402 is adjusted inside the thread groove 3031, and the adjusting shaft 403 drives the feeding spindle 303 to rotate.

[0072] By rotating the feeding main shaft 303, the feeding auger 302 rotates accordingly. During the rotation process, smaller feed first enters the throwing component 2 through the filter hole and is then thrown by the throwing component 2 to the fish school that is farther away from the device and smaller in size. The rotation of the feeding auger 302 makes the feed stratified in the feeding bin 301, ensuring that feeds of different particle sizes enter the throwing component 2 in turn, so as to feed accurately, meet the needs of various fish schools, and improve feeding efficiency.

[0073] Start the motor 17, the motor 17 drives the feeding assembly 3 to rotate, and the feed in the feed trough 2033 moves into the guide groove 2032 under the action of centrifugal force. Due to the obstruction of the movable block 213 in the guide groove 2032, the feed accumulates in the straight groove of the guide groove 2032. When it accumulates to a certain amount, by starting the motor 206, the motor 206 drives the first-stage gear 207 and the second-stage gear set 208 to rotate, and the second-stage gear set 208 drives the positioning rack 210 to move toward the center of the throwing plate 203. During the movement of the positioning rack 210, the movable block 213 also moves toward the center of the throwing plate 203 in the guide groove 2032. When the termination gear 211 is meshed with the second-stage gear set 208, the movable block 213 moves to the adjusting groove of the guide groove 2032, opens the straight groove for accumulating feed, and the feed is quickly thrown into the fish school area under the action of centrifugal force.

[0074] Embodiment 2: Based on embodiment 1, the feeding machine also has the function of adjusting the throwing distance. By adjusting the meshing position of the secondary gear set 208 and the termination gear 211, the moving distance of the movable block 213 is changed, and the feed throwing range is accurately controlled to ensure that fish in different areas can obtain the right amount of feed.

[0075] Specifically, when it is necessary to adjust the secondary gear set 208, the electric push rod 2092 is started, the telescopic rod is extended into the push rod body, and the telescopic rod drives the middle gear 2082 and the large gear 2083 to move upward synchronously through the sliding rod 2093 and the fixed rod 2094. When the middle gear 2082 includes one of the small gears 2081, the electric push rod 2092 is controlled to stop. When it is necessary to continue to adjust the secondary gear set 2088, the electric push rod 2092 is started to make the telescopic rod continue to retract into the push rod body, and the telescopic rod drives the large gear 2083 to move upward. During the movement, the middle gear 2082 does not move, and the spring 2095 is gradually compressed. When the large gear 2083 includes the middle gear 2082, the electric push rod 2092 is controlled to stop working again, and the adjustment of the secondary gear set 208 is completed.

[0076] When throwing feed to a school of fish that is relatively close to the device, the secondary gear set 208 is adjusted to make the terminating gear 211 mesh with the pinion 2081. Since the feed is relatively close to the center of the throwing plate 203, the centrifugal force is small and the throwing range is relatively small.

[0077] When throwing feed to a school of fish far away from the device, the secondary gear set 208 is adjusted to make the end gear 211 mesh with the middle gear 2082, thereby increasing the centrifugal force and expanding the throwing range.

[0078] When throwing feed to fish schools farther away from the device, the secondary gear set 208 is adjusted to make the end gear 211 mesh with the large gear 2083, the centrifugal force is significantly enhanced, and the throwing range is further expanded to ensure that the feed accurately covers fish schools in farther areas. At the same time, since the feeding auger 302 is provided with filtering holes, the fine particles of feed first enter the throwing assembly 2 during the conveying process, which is more suitable for small fish to eat.

[0079] Through this fine-tuning mechanism, not only the efficiency of feed utilization is improved, but also environmental pollution is reduced, the needs of different fish populations are accurately met, and the harmonious coexistence of technology and ecology is demonstrated.

[0080] Embodiment 3: Based on embodiment 1, the feeding machine also has the function of fully stirring the feed, and through the synergistic effect of the feeding auger 302 and the regulating auger 402, the feed is ensured to be evenly mixed to prevent agglomeration.

[0081] Specifically, the hydraulic rod 6 is started, and the hydraulic rod 6 drives the regulating bin 401 to descend, and the motor 3 404 is started to make the regulating auger 402 completely enter the thread groove 3031. At this time, the regulating shaft 403 is inside the feeding main shaft 303, and the feed conveying is accelerated through the synergistic effect of the feeding auger 302 and the regulating auger 402. The descent of the regulating bin 401 further compresses the feeding bin 301, thereby enhancing the fluidity of the feed.
