[0059] Semicircular plates 11 are fixedly installed on the upper ends of the left and right side walls of the frame 10, and a semicircular shovel 12 is rotatably installed between the two semicircular plates 11. The semicircular shovel 12 is movably installed inside the frame 10 and above the bottom wall of the frame 10. The frame 10 and the two semicircular plates 11 form a fixed structure, which provides space for the semicircular shovel 12 to rotate. The semicircular shovel 12 can rotate inside the frame 10 under the drive of the rotating mechanism described later. When the shovel of the semicircular shovel 12 is facing upward, it can expose the feed to the outside for easy feeding of livestock. When the semicircular shovel 12 rotates once, it can shovel the feed located in the lower frame 10 upward into its interior, and finally drive it to flip upward until the feed is fully loaded.

[0060] The semi-circular shovel 12 is driven to rotate by a rotating mechanism. A first rectangular through hole 1001 is provided on the rear wall of the frame 10. A box 14 is fixedly installed on the rear wall of the frame 10. The first rectangular through hole 1001 and the box 14 are connected. A pushing mechanism for pushing feed is installed inside the box 14. When the shovel of the semi-circular shovel 12 rotates into the frame 10, the pushing mechanism pushes the feed into the frame 10. At this time, the feed can be scooped up and flipped upward by the semi-circular shovel 12.

[0061] The semi-circular shovel 12 drives the pushing mechanism to work through rotation;

[0062] The upper end of the box body 14 is provided with a second rectangular through hole 1401, and a feed box 1 is fixedly installed on the upper end of the box body 14. The second rectangular through hole 1401 is connected to the feed box 1.

[0064] The tilting mechanism is driven by the pushing mechanism.

[0065] A top frame 2 is fixedly installed on the top outer wall of the feed box 1. The top end of the top frame 2 is provided with a third rectangular through hole. A sliding cover 3 is slidably installed in the third rectangular through hole. A handrail 4 is fixedly installed on the top wall of the sliding cover 3. External feed can be added into the feed box 1 by opening the sliding plate 3. The opening and closing plate 13 at the bottom of the feed box 1 will open before the feeding mechanism pushes the feed and send the feed in the feed box 1 into the box body. When the feeding mechanism pushes the feed in the box body 14 into the frame body 10, it will flip upward until the bottom wall of the feed box 1 is closed.

[0066] Several ventilation holes 202 are provided on the left and right side walls of the top frame 2;

[0067] The left and right side walls of the third rectangular through hole are respectively provided with rectangular sliding grooves 201, and the left and right side walls of the sliding cover 3 are respectively fixedly installed with guide plates 301.

[0068] Two guide plates 301 are slidably installed in rectangular troughs 201 that are close to them. Since the feed will be stored in the feed box 1 for a long time, the ventilation holes 202 on both sides can provide airflow in the feed box 1 to prevent the feed from becoming moldy in a closed space for a long time.

[0069] The rotating mechanism is a crank 8;

[0070] The crank 8 is rotatably mounted at the center of the outer wall of the semicircular plate 11 located on the right side via the first rotating shaft;

[0071] The first rotating shaft is fixedly connected to the right wall center of the adjacent semicircular plate 11 and semicircular shovel 12. By rotating the handle 8, the coaxially fixed semicircular shovel 12 can be driven to start rotating. A flexible pad that can rotate can be fitted on the outer wall of the handle 8 to make it easier for the user to operate with less effort.

[0072] The feeding mechanism includes a rectangular slider 1501, a feeding plate 15, a connecting rod 20, and a disc 19;

[0073] The first end of the second rotating shaft is fixedly installed at the center of the left side wall of the semi-circular shovel 12, and the second end of the second rotating shaft rotates through the center of the semi-circular plate 11 which is fixedly installed with a disc 19.

[0074] A first connecting shaft is fixedly installed at an eccentric position on the outer wall of the disc 19, and the first end of the connecting rod 20 is mounted on the outer wall of the first connecting shaft via a rotating sleeve.

[0075] Rectangular through slots 1402 are provided on the left and right side walls of the housing 14 respectively. Rectangular sliders 1501 are slidably installed in the two rectangular through slots 1402 respectively. The same pusher plate 15 is fixedly installed between the two rectangular sliders 1501. The pusher plate 15 is movably installed in the housing 14 and is movably installed on the rear side of the first rectangular through hole 1001.

[0076] The rectangular slider 1501 located on the left slides through the adjacent rectangular through slot 1402 and is fixedly installed with the second connecting shaft;

[0077] The second end rotating sleeve of the connecting rod 20 is mounted on the outer wall of the second connecting shaft;

[0078] The rectangular slider 1501 located on the right operates via a sliding-driven flipping mechanism, see reference. Figure 5 When the semi-circular shovel 12 rotates, it drives the disc 19, which is fixedly installed on the same axis, to start rotating. During the rotation of the disc 19, the connecting rod 20 starts to reciprocate. During the reciprocating deflection of the connecting rod 20, the rectangular slider 1501 that cooperates with it can slide left and right along the rectangular through groove 1402 that is close to it. The pusher plate 15, which is fixedly installed with the rectangular slider 1501, can then start to slide left and right in the box 14. When the pusher plate 15 is located near the right side wall of the box 14, the shovel mouth of the semi-circular shovel 12 faces upward. When the pusher plate 15 slides towards the left side wall of the box 14, the semi-circular shovel 12 will start to rotate downward and scoop up the feed located in the frame 10. When the semi-circular shovel 12 rotates one revolution, the pusher plate 15 slides back and forth once.

[0079] The flipping mechanism includes a first spur gear 17, a second spur gear 18, and a rack plate 16;

[0080] The bottom wall of the feed box 1 is provided with a fourth rectangular through hole, which is connected to the second rectangular through hole 1401;

[0081] The right side wall of the hinge plate 13 is rotatably installed in the fourth rectangular through hole via the third pivot.

[0082] The third rotating shaft rotates through the right side wall of the feed box 1 and is fixedly installed with the first spur gear 17. The lower end of the first spur gear 17 is meshed with the second spur gear 18. The second spur gear 18 is rotated and installed on the right side wall of the box body 14 through the fourth rotating shaft.

[0083] The lower end of the second spur gear 18 is fitted with a rack plate 16;

[0084] The rectangular slider 1501 located on the right side slides through the adjacent rectangular through slot 1402 and is fixedly connected to the bottom wall of the rack plate 16, for reference. Figure 4As the pusher plate 15 slides back and forth, the rectangular slider 1501 on the right side also slides back and forth, and in the process of sliding back and forth, it drives the rack plate 16 fixedly installed with it to slide back and forth. The second spur gear 18, which meshes with the rack plate 16, also starts to rotate back and forth and drives the first spur gear 17 to start to rotate back and forth. The opening and closing plate 13, which is fixedly installed coaxially with the first spur gear 17, can then have the ability to flip back and forth. When the opening and closing plate 13 is flipped to the top, the pusher plate 15 is at the rear and provides space for the feed that is about to fall off. After the feed falls to the front of the pusher plate 15, the opening and closing plate 13 starts to flip down and finally blocks the bottom wall of the feed box 1. At this time, the pusher plate 15 starts to move forward and pushes the fallen feed into the frame 10.

[0085] A placement plate 6 is fixedly installed on the middle of the right side wall of the feed box 1, and the placement plate 6 is installed above the first spur gear 17;

[0086] A water storage tank 5 is installed on the upper end of the placement plate 6, and the placement plate 6 provides space for the water storage tank 5.

[0087] A water tank 21 is fixedly installed on the right side of the front wall of the frame 10;

[0088] The first end of the water pipe 7 is connected to the front wall of the water storage tank 5, and the second end of the water pipe 7 is installed inside the water feeding tank 21.

[0089] A valve 9 is installed at the upper end of the water pipe 7. By opening the valve 9, the water in the water storage tank 5 can be introduced into the water feeding tank 21 through the water pipe 7, which facilitates the provision of drinking water for livestock.

[0090] The implementation method of this utility model:

[0091] Place the device on a horizontal surface, pull the sliding cover 3 backward by holding the handle 4 to open the top frame 2, put fresh feed into the feed box 1 from the top of the top frame 2, and inject fresh drinking water into the water storage tank 5. There are pipes for water injection on the side wall of the water storage tank 5.

[0092] When the equipment is in its initial state, the semi-circular shovel 12 is fully loaded with feed, and the shovel opening is facing upwards. The pusher plate 15 is located on the rear side of the box 14, and the opening and closing plate 13 is in the open state. The feed in the feed box 1 is constantly replenishing the feed in the box 14.

[0093] When the feed in the semi-circular shovel 12 is finished, the crank 8 is turned. As the crank 8 rotates once, it also drives the semi-circular shovel 12 to rotate once. As the shovel of the semi-circular shovel 12 rotates downward, the pusher plate 15 continuously pushes the feed towards the frame 10. When the feed enters the frame 10, the shovel of the semi-circular shovel 12 just scoops up the feed in the frame 10. During this process, the opening and closing plate 13 also begins to gradually flip up and close, preventing the feed from falling out of the feed box 1.

[0094] When the shovel of the semi-circular shovel 12 rotates to the top again, it will be full of feed. During this process, the pusher plate 15 starts to slide backward again, and the opening and closing plate 13 at the bottom of the feed box 1 opens again to replenish the feed in the box 14. At this time, the front of the pusher plate 15 is full of feed again. When the feed in the semi-circular shovel 12 is used up again, the above operation can be repeated to replenish it.

[0095] When the water in the water tank 21 is used up, simply open the valve 9 to replenish the water in the storage tank 5 through the water pipe 7.

[0096] This device simply requires placing feed in the feed box and replenishing the livestock feed by turning the crank. The top frame of the feed box has ventilation holes on the side wall to prevent the feed from getting moldy even after long-term storage. By turning the crank once, the feed in the feed box is moved into the box body. The feed in the box body is then pushed into the frame body by the pushing mechanism, and then shoveled into the semi-circular shovel by the rotation of the semi-circular shovel, thus realizing feeding. The whole process greatly reduces the workload of the feeders when feeding.

[0097] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
