Description

Technical Field

[0001] This utility model belongs to the field of hay conveying, and in particular relates to an automatic hay unbundling and conveying device. Background Technology

[0002] To ensure livestock receive balanced nutrition at different growth and development stages, workers add varying proportions of protein, lipids, carbohydrates, vitamins, and minerals to the forage, providing comprehensive nutritional support. The forage and nutrients are then processed into feed pellets using a pellet mill. Compared to directly feeding crushed feed, this method reduces waste and improves feed utilization. The extruded feed pellets are also harder, providing a chewing aid for the animals. Furthermore, the higher density of the pellets reduces volume, making them easier to package and transport. However, the entire production line is quite large, and manual removal of the binding strips from the bales is time-consuming and inefficient. Therefore, an automatic unbundling and feeding device is needed. Summary of the Invention

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example

[0050] like Figures 1-12 As shown, an automatic bale feeding conveyor includes a base 1, a cutting blade 2, and a bale positioning arc plate 3 mounted on the base 1. A cutting guide groove 4 is provided at the bottom center of the bale positioning arc plate 3. Two side T-plates 5 are symmetrically arranged on the base 1, and the two side T-plates 5 form a limiting guide rail 6. The two side T-plates 5 are located at the bottom of the bale positioning arc plate 3, and the limiting guide rail 6 corresponds to the cutting guide groove 4.

[0051] like Figure 3 and Figure 4 As shown, a support platform 9 is integrally provided on one side of the base 1, and multiple first side brackets 14 are fixedly connected to one side of the support platform 9. The multiple first side brackets 14 are in contact with the outer wall of the bale positioning arc plate 3.

[0052] Multiple second side brackets 15 are fixedly connected to the base 1. The multiple second side brackets 15 are located on the side of the hay bale positioning arc plate 3 away from the support platform 9, and the multiple second side brackets 15 are in contact with the outer wall of the hay bale positioning arc plate 3. The outer wall of the hay bale positioning arc plate 3 can be supported by the first side brackets 14 and the second side brackets 15.

[0053] The bale positioning arc plate 3 is symmetrically provided with limiting outer plates 36 for limiting the bale. In use, the bale is transported to the bale positioning arc plate 3 by a conveyor, so that the bale is located between the two limiting outer plates 36.

[0054] like Figure 1 and Figure 3 As shown, a directional adjustment structure is slidably connected to the limiting guide rail 6. The cutting blade 2 is mounted on the directional adjustment structure and is located directly below the cutting guide groove 4. The directional adjustment structure is used to adjust the angle of the cutting blade 2 according to its movement state, specifically as follows: Figures 8-11 As shown, the directional adjustment structure includes a cross-shaped sliding block 16, which is slidably connected to the limiting guide rail 6, as follows. Figure 9 As shown, the cross sliding block 16 has a top groove 17 and two pull grooves 18. The top groove 17 is located between the two pull grooves 18. The cross sliding block 16 also has two symmetrical shaft limiting grooves 19. The top groove 17 is connected to the pull grooves 18 through the shaft limiting grooves 19.

[0055] The same docking shaft 20 is slidably connected to the two shaft limiting grooves 19, and the two ends of the docking shaft 20 extend into the two pulling grooves 18 respectively;

[0056] A docking slider 21 is fixedly connected to the docking shaft 20. The docking slider 21 is located in the top groove 17 and slides in contact with the cross sliding block 16. The cutting blade 2 is inserted into the docking slider 21. Figure 10 As shown, the cross sliding block 16 is also provided with a blade avoidance groove 22 corresponding to the cutting blade 2, so as to prevent the cross sliding block 16 from damaging the cutting blade 2 when the cutting blade 2 moves;

[0057] Furthermore, a rectangular top block 23 is provided on one side of the top groove 17, and an arc-shaped surface 24 is provided on the side of the docking slider 21 near the rectangular top block 23;

[0058] The top of the cross-shaped sliding block 16 is fixedly connected to a U-shaped locking plate 25, which is connected to the top groove 17.

[0059] Furthermore, both ends of the docking shaft 20 are fitted with pull rods 26, and the free ends of the two pull rods 26 are fixed with the same docking block 27. The pull rods 26 are connected to the drive structure through the docking block 27.

[0060] like Figure 1 and Figure 12 As shown, a drive structure is provided on the base 1. The drive structure includes a rotary motor 28 fixedly installed on the base 1. Two drive gears 29 distributed vertically are fixedly connected to the rotation shaft of the rotary motor 28.

[0061] A positioning rod 30 is inserted into the base 1. Two limiting clamps 31 distributed vertically are fixedly connected to the positioning rod 30. A first rack 32 is slidably connected to the lower limiting clamp 31. The first rack 32 meshes with the lower drive gear 29, and one end of the first rack 32 is fixedly connected to the docking block 27 through a pin.

[0062] A second rack 33 is slidably connected to the upper limiting clamp 31, and the second rack 33 meshes with the upper drive gear 29.

[0063] Specifically, during cutting, the rotary motor 28 drives two gears to rotate counterclockwise via the rotating shaft. Under meshing action, the first rack 32 and the second rack 33 begin to slide forward. The first rack 32 drives the pull rod 26 to move forward via the docking block 27. The pull rod 26 pushes the docking shaft 20 to slide forward along the shaft limiting groove 19, thereby driving the docking slider 21 and the cutting blade 2 inserted on the docking slider 21 to move forward. During the forward movement of the docking slider 21, when the arc surface 24 touches the side edge of the rectangular top block 23, the docking slider 21 will be lifted up, causing the docking slider 21 to rotate clockwise around the docking shaft 20 as the rotation center, and continue to move forward with the docking slider 21. When the vertical surface of the rectangular top block 23 abuts against the bottom of the docking slider 21, the cutting blade 2 on the docking slider 21 is perpendicular to the ground, and the cutting blade 2 extends out from the cutting guide groove 4.

[0064] At this time, as the docking slider 21 continues to move forward, the docking slider 21 will push the rectangular top block 23, and the cross sliding block 16 will slide forward along the limiting guide rail 6, thereby causing the cutting blade 2 to move forward along the cutting guide groove 4, cutting the bottom of the straw bale that is stuck on the straw bale positioning arc plate 3, and cutting off the binding strips tied to the straw bale.

[0065] like Figure 12 As shown, a rope-collecting assembly is provided on one side of the bale positioning arc plate 3. Specifically, the rope-collecting assembly includes a limiting outer frame 34 and a bending plate 35. The top of the limiting outer frame 34 is fixedly connected to the bottom of the second toothed rack 33 located above it. The bending plate 35 is rotatably connected to the inner wall of the limiting outer frame 34. Specifically, during the cutting process, the second toothed rack 33 will also slide forward synchronously under the action of meshing, thereby driving the limiting outer frame 34 and the bending plate 35 to move forward. The bottom of the limiting outer frame 34 is inclined, and the bottom of its inner wall abuts against the bottom of the bending plate 35. Thus, during the forward movement of the bending plate 35, the bottom of the bending plate 35 will form an angle with the top of the bale, and the resistance between the bending plate 35 and the upper surface of the bale will increase. At the same time, the bottom of the inner wall of the limiting outer frame 34 will limit the bending plate 35, improve the stability during pushing, so as to push the cut binding strip forward and push out the cut binding strip.

[0066] Furthermore, the bending plate 35 is located on the side of the second rack 33 near the rotary motor 28, so that during the forward movement, it will first cut the binding strip and then push out the cut binding strip.

[0067] like Figure 2 As shown, a storage box 37 for storing ropes is placed on the base 1; an inclined part 38 is provided on the limiting outer plate 36 on the side away from the drive structure, and one side of the storage box 37 contacts the bottom edge of the inclined part 38. The bundle strips that are pushed out will fall into the storage box 37 along the inclined part 38 for temporary storage.

[0068] After cutting, the rotary motor 28 drives the two gears to rotate clockwise through the rotating shaft. Under meshing, the first rack 32 and the second rack 33 begin to slide backward. The first rack 32 drives the pull rod 26 to move backward through the docking block 27. The pull rod 26 pulls the docking shaft 20 to slide backward along the shaft limiting groove 19, thereby driving the docking slider 21 and the cutting blade 2 inserted on the docking slider 21 to move backward. During the backward movement of the docking slider 21, the inner wall of the U-shaped plate 25 will block the docking slider 21. As the pull rod 26 continues to pull the docking shaft 20 to slide backward along the shaft limiting groove 19, the docking slider 21 and the cutting blade 2 are retracted into the top groove 17 to prevent the back of the cutting blade 2 from interfering with the bale when it moves backward. When the docking shaft 20 slides to the side of the shaft limiting groove 19 close to the rotary motor 28, the docking shaft 20 will push the inner wall of the shaft limiting groove 19, thereby driving the cross sliding block 16 to slide backward and reset.

[0069] At the same time, the second rack 33 will also slide backward under the action of meshing, thereby driving the limiting frame 34 and the bending plate 35 to move backward. At this time, the bottom of the inner wall of the limiting frame 34 will not limit the bending plate 35. At the same time, when the bending plate 35 contacts the upper surface of the straw bale, the bending plate 35 will rotate clockwise in the limiting frame 34 so that the bending plate 35 can be reset.

[0070] like Figures 3-7 As shown, the bottom of the bale positioning arc plate 3 is provided with a lifting structure, which includes a lifting hydraulic rod 7 and a limiting sleeve rod 8. The lifting hydraulic rod 7 is symmetrically installed on the support platform 9. The bale positioning arc plate 3 is provided with a sliding groove 10 on the side near the support platform 9. The telescopic end of the lifting hydraulic rod 7 is rotatably connected to a sliding rod 11. The two ends of the sliding rod 11 are slidably connected to the sliding groove 10. The sliding groove 10 allows the sliding rod 11 to slide in the sliding groove 10, preventing interference during lifting.

[0071] Multiple sets of limiting sleeve rods 8 are fixedly connected to the base 1. The bottom of the hay bale positioning arc plate 3 away from the support platform 9 is fixedly connected to a connecting ear 12 corresponding to the multiple sets of limiting sleeve rods 8. The multiple connecting ears 12 are fixedly connected to the same shaft 13. The top of the limiting sleeve rod 8 is rotatably sleeved on the shaft 13.

[0072] Specifically, after the directional structure, rope collecting assembly and drive structure are reset, the lifting hydraulic rod 7 is activated. The sliding rod 11 is lifted upward through the telescopic end of the lifting hydraulic rod 7. The sliding rod 11 lifts one side of the bale positioning arc plate 3. At this time, the bale positioning arc plate 3 will rotate counterclockwise around the shaft 13 to discharge the bale in the bale positioning arc plate 3.

[0073] In summary, the workflow of this utility model is as follows:

[0074] The bales are transported to the bale positioning arc plate 3 by a conveyor, so that the bales are positioned between the two limiting outer plates 36. The rotary motor 28 drives the two gears to rotate counterclockwise through the rotating shaft. Under the meshing action, the first rack 32 and the second rack 33 begin to slide forward. The first rack 32 drives the pull rod 26 to move forward through the docking block 27. The pull rod 26 pushes the docking shaft 20 to slide forward along the shaft limiting groove 19, thereby driving the docking slider 21 and the cutting blade 2 inserted on the docking slider 21 to move forward. During the forward movement of the docking slider 21, when the arc surface 24 touches the side edge of the rectangular top block 23, the docking slider 21 will be lifted up, so that the docking slider 21 rotates clockwise around the docking shaft 20 as the rotation center, and continues to move forward with the docking slider 21. When the vertical surface of the rectangular top block 23 abuts against the bottom of the docking slider 21, the cutting blade 2 on the docking slider 21 is perpendicular to the ground and extends out from the cutting guide groove 4.

[0075] At this time, as the docking slider 21 continues to move forward, the docking slider 21 will push the rectangular top block 23, and the cross sliding block 16 will slide forward along the limiting guide rail 6, thereby causing the cutting blade 2 to move forward along the cutting guide groove 4, cutting the bottom of the straw bale that is stuck on the straw bale positioning arc plate 3, and cutting off the binding strips tied to the straw bale.

[0076] At the same time, the second rack 33 will also slide forward synchronously under the action of meshing, thereby driving the limiting frame 34 and the bending plate 35 to move forward. During the forward movement of the bending plate 35, the bottom of the bending plate 35 will form an angle with the top of the straw bale, and the resistance between the bending plate 35 and the upper surface of the straw bale will increase. Meanwhile, the bottom of the inner wall of the limiting frame 34 will limit the bending plate 35, improve the stability when pushing, so as to push the cut binding strip forward and push out the cut binding strip.

[0077] After being pushed out, the binding strip will fall along the inclined part 38 into the storage box 37 for temporary storage;

[0078] After cutting, the rotary motor 28 drives the two gears to rotate clockwise through the rotating shaft. Under meshing, the first rack 32 and the second rack 33 begin to slide backward. The first rack 32 drives the pull rod 26 to move backward through the docking block 27. The pull rod 26 pulls the docking shaft 20 to slide backward along the shaft limiting groove 19, thereby driving the docking slider 21 and the cutting blade 2 inserted on the docking slider 21 to move backward. During the backward movement of the docking slider 21, the inner wall of the U-shaped plate 25 will block the docking slider 21. As the pull rod 26 continues to pull the docking shaft 20 to slide backward along the shaft limiting groove 19, the docking slider 21 and the cutting blade 2 are retracted into the top groove 17 to prevent the back of the cutting blade 2 from interfering with the bale when it moves backward. When the docking shaft 20 slides to the side of the shaft limiting groove 19 close to the rotary motor 28, the docking shaft 20 will push the inner wall of the shaft limiting groove 19, thereby driving the cross sliding block 16 to slide backward and reset.

[0079] At the same time, the second rack 33 will also slide backward under the action of meshing, thereby driving the limiting frame 34 and the bending plate 35 to move backward. At this time, the bottom of the inner wall of the limiting frame 34 will not limit the bending plate 35. At the same time, when the bending plate 35 is in contact with the upper surface of the straw bale, the bending plate 35 will rotate clockwise in the limiting frame 34 so that the bending plate 35 can be reset.

[0080] After resetting, the lifting hydraulic rod 7 is activated, and the sliding rod 11 is lifted upward through the telescopic end of the lifting hydraulic rod 7. The sliding rod 11 lifts one side of the bale positioning arc plate 3. At this time, the bale positioning arc plate 3 will rotate counterclockwise around the shaft 13, discharging the bale from the bale positioning arc plate 3.

[0081] However, as is well known to those skilled in the art, the working principle and wiring method of the lifting hydraulic rod 7 and the rotating motor 28 are commonplace and are all conventional means or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
