[0050] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0051] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0052] In some embodiments, please refer to the accompanying drawings. Figures 1-8 An automatic feeding device for pig farms includes a storage bin 1, a auger conveyor 9, a mixing and feeding mechanism, an adjustable dispensing mechanism, a rotation control mechanism, a surplus feed bin 10, a receiving hopper 19, a receiving box 20, and a separator 23; the storage bin 1 is fixedly installed on the ground by a bracket.

[0053] The storage hopper 1 is equipped with a stirring and feeding mechanism to prevent feed from clumping.

[0054] The auger conveyor 9 is located below the mixing and feeding mechanism; and the auger conveyor 9 is also fixedly installed on the ground by a bracket.

[0055] The auger conveyor 9 has a feed inlet on its left side and a discharge outlet on its right side.

[0056] The Jiaolong conveyor 9 is equipped with multiple adjustable feeding mechanisms that allow for easy adjustment of the amount of feed fed at one time.

[0057] like Figure 1 As shown, the adjustable material distribution mechanism includes a fixed receiving component, a capacity adjustment component, and a flat valve 181; the fixed receiving component is connected to the auger conveyor 9; the capacity adjustment component is connected to the fixed receiving component; the flat valve 181 is installed below the capacity adjustment component;

[0058] The divider 23 is located below the multiple sets of capacity adjustment components; and the divider 23 is fixedly installed on the ground.

[0059] The waste material bin 10 is located below the discharge port of the auger conveyor 9; and the waste material bin 10 is placed on the upper right side of the separator 23; and a retaining plate for restricting the movement of the waste material bin 10 is fixedly installed on the upper right side of the separator 23.

[0060] The receiving hopper 19 is located below the capacity adjustment component; and the receiving hopper 19 is fixedly connected to the upper end of the separator 23;

[0061] The receiving hopper 19 is located below the capacity adjustment component; and the receiving hopper 19 is fixedly connected to the upper end of the separator 23;

[0062] A rotation control mechanism for controlling the rotation of the receiving box 20 is installed on the lower side of the separator 23;

[0063] Multiple feed boxes 20 are installed on the rotation control mechanism; the feed boxes 20 are provided with feed troughs 201 to facilitate feeding of pigs;

[0064] The area behind the partition frame 23 is designated as a pig activity area; the area in front of the partition frame 23 is designated as a walking area for breeding operators.

[0065] In this utility model, the mixing and feeding mechanism moves the pig feed stored in the storage tank 1 into the feed inlet of the auger conveyor 9; then the auger conveyor 9 moves the pig feed to the right. When the pig feed moves to the position of the leftmost fixed receiving component, it will continuously fall into the fixed receiving component and fall from below the fixed receiving component into the capacity adjustment component, and be blocked by the flat valve 181.

[0066] The process continues until the leftmost fixed receiving assembly and capacity adjustment assembly are filled with pig feed. At this point, the pig feed will block the channel between the leftmost fixed receiving assembly and the auger conveyor 9, allowing the pig feed in the auger conveyor 9 to continue moving to the next fixed receiving assembly. This process is repeated until all fixed receiving assemblies and capacity adjustment assemblies are filled with pig feed. Finally, any remaining pig feed in the auger conveyor 9 will be moved from the discharge port on the right side of the auger conveyor 9 into the waste bin 10 for easy recycling by operators.

[0067] Subsequently, the flat valves 181 installed on all the capacity adjustment components work simultaneously to release the blockage below the capacity adjustment components. Then, the pig feed filled in the fixed receiving components and the capacity adjustment components will fall into the receiving hopper 19 below, and finally into the receiving trough 201, after which the pigs can start feeding.

[0068] Since pigs of different sizes have different feed intakes, the operator can adjust the distance between the capacity adjustment component above the corresponding feed trough 201 and the lower part of the fixed feed receiving component before feeding, thereby increasing or decreasing the available volume in the fixed feed receiving component and the capacity adjustment component. This makes the operation convenient and improves the practicality of the device.

[0069] After feeding is completed, the operator can also control multiple receiving boxes 20 to rotate forward by rotating the control mechanism, which makes it convenient for the operator to clean the receiving trough 201;

[0070] like Figures 6-8As shown, the mixing and feeding mechanism includes a mixing shaft 2, a spiral plate 3, a drive motor 4, an arc-shaped baffle plate 5, an inclined plate box 6, and a push cylinder 7; a discharge chute 11 for easy discharge is provided on the lower right side of the storage tank 1.

[0071] The stirring shaft 2 is rotatably installed at the bottom of the storage tank 1; a spiral plate 3 is fixedly installed on the stirring shaft 2; the drive motor 4 is fixedly installed at the lower end of the storage tank 1; and the output end of the drive motor 4 is fixedly connected to the stirring shaft 2.

[0073] A sealing groove 8 is provided on the right side of the inclined plate box 6; the arc-shaped baffle plate 5 is slidably connected to the sealing groove 8; and the left end of the arc-shaped baffle plate 5 is slidably connected to the right outer wall of the storage barrel 1; the push cylinder 7 is fixedly installed at the front end of the inclined plate box 6; and the output end of the push cylinder 7 is fixedly connected to the upper end of the arc-shaped baffle plate 5 through a connecting frame.

[0074] like Figure 5 As shown, the fixed receiving assembly includes a fixed clamp 12 and a fixed discharge pipe 13; the lower end of the auger conveyor 9 is provided with multiple clearance grooves 111;

[0075] Multiple fixing clamps 12 are fitted onto the outer end of the auger conveyor 9 and are fixedly connected to the auger conveyor 9; a clearance groove 111 is also provided on the lower side of the fixing clamps 12;

[0076] A fixed discharge pipe 13 is also fixedly installed at the lower end of the fixed clamp 12; the fixed discharge pipe 13 is connected to the relief groove 111; the fixed discharge pipe 13 is connected to the capacity adjustment component.

[0077] like Figure 3 and Figure 5 As shown, the capacity adjustment assembly includes a movable discharge pipe 14, an L-shaped fixing plate 15, a lead screw 16, a vertical guide rod 17, an adjustment knob 18, and a flat valve 181;

[0078] The movable discharge pipe 14 is sleeved on the outer end of the fixed discharge pipe 13 and is slidably connected to the fixed discharge pipe 13 in a limiting manner.

[0079] Both the left and right ends of the fixed discharge pipe 13 and the movable discharge pipe 14 are fixedly installed with L-shaped fixing plates 15;

[0080] The upper end of the lead screw 16 is rotatably connected to the L-shaped fixing plate 15 on the left side of the fixed discharge pipe 13; the upper end of the vertical guide rod 17 is fixedly connected to the L-shaped fixing plate 15 on the right side of the fixed discharge pipe 13.

[0081] The L-shaped fixing plate 15 on the left side of the movable discharge pipe 14 is threadedly connected to the lead screw 16; the L-shaped fixing plate 15 on the right side of the movable discharge pipe 14 is limited and slidably connected to the vertical guide rod 17.

[0082] The adjusting knob 18 is rotatably mounted on the upper end of the L-shaped fixing plate 15 on the left side of the fixed discharge pipe 13; and the adjusting knob 18 is fixedly connected to the lead screw 16.

[0083] A flat valve 181 is fixedly installed at the lower end of the movable discharge pipe 14;

[0084] The fixed discharge pipe 13 is connected to the movable discharge pipe 14;

[0085] like Figure 4 As shown, the rotation control mechanism includes a drive shaft 21, a control motor 22, a vertical plate 24, and a synchronous transmission assembly 25; the vertical plate 24 is fixedly installed on the lower left side of the partition frame 23; the control motor 22 is fixedly installed on the left side of the vertical plate 24 through a U-shaped support frame; the drive shaft 21 is rotatably installed on the lower end of the partition frame 23; and multiple receiving boxes 20 are fixedly installed on the drive shaft 21.

[0086] Synchronous transmission assembly 25 is installed at the left end of vertical plate 24;

[0087] The output end of the control motor 22 is connected to the drive shaft 21 via the synchronous transmission assembly 25.

[0088] The synchronous transmission assembly 25 adopts a synchronous belt transmission assembly;

[0089] In this utility model, the push cylinder 7 pushes the arc-shaped baffle plate 5 to move upward along the sealing groove 8, opening the channel between the discharge chute 11 and the inclined plate box 6. Then the pig feed stored in the storage bucket 1 will move from the discharge chute 11 to the inclined plate box 6, and then move along the inclined plate box 6 to the feed inlet of the auger conveyor 9.

[0090] At the same time, the drive motor 4 drives the stirring shaft 2 to rotate, so that the spiral plate 3 rotates synchronously and continuously stirs the feed in the storage tank 1 to prevent the feed from clumping.

[0091] Subsequently, the auger conveyor 9 operates, causing the pig feed to move to the right. When the pig feed moves to the position of the leftmost fixed discharge pipe 13, it will continuously fall into the fixed discharge pipe 13 through the clearance groove 111, and fall from below the fixed discharge pipe 13 into the movable discharge pipe 14, where it is blocked by the flat valve 181.

[0092] The process continues until the leftmost fixed discharge pipe 13 and movable discharge pipe 14 are filled with pig feed. At this point, the pig feed will block the passage between the leftmost fixed discharge pipe 13 and the clearance trough 111, allowing the pig feed in the auger conveyor 9 to continue moving to the next fixed discharge pipe 13. This process is repeated until all fixed discharge pipes 13 and movable discharge pipes 14 are filled with pig feed. Finally, any remaining pig feed in the auger conveyor 9 will be removed from the discharge port on the right side of the auger conveyor 9 and placed in the waste bin 10 for easy recycling by the operators.

[0093] Subsequently, the flat valves 181 installed below all the movable discharge pipes 14 work simultaneously to release the blockage below the movable discharge pipes 14. Then, the pig feed filled in the fixed discharge pipe 13 and the movable discharge pipe 14 will fall into the receiving hopper 19 below, and finally into the receiving trough 201, after which the pigs can start feeding.

[0094] Since pigs of different sizes have different feed intakes, the operator can turn the adjustment knob 18 above the corresponding feed trough 201 before feeding. The adjustment knob 18 drives the screw 16 to rotate, so that the L-shaped fixing plate 15 on the left side of the movable feed pipe 14 drives the movable feed pipe 14 to move up or down along the vertical guide rod 17, thereby reducing or expanding the available volume of the fixed feed pipe 13 and the movable feed pipe 14.

[0095] After feeding is completed, the control motor 22 drives the synchronous transmission component 25 to rotate, causing the drive shaft 21 to rotate. At this time, the drive shaft 21 will drive multiple feed boxes 20 to rotate simultaneously towards the walking area of ​​the breeding operator, making it convenient for the operator to clean the feed trough 201.

[0096] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
