Description

Technical Field

[0001] This utility model belongs to the field of grass production and processing, and relates to an automatic grass bale correction, unbundling and rope-pulling machine. Background Technology

[0002] Currently, with the need for large-scale production, the demand for livestock products and paper packaging is gradually increasing, and the use of forage and various types of straw is increasing. The demand for unbundling in straw processing is also increasing. Unbundling is not only labor-intensive, inefficient, time-consuming, and labor-intensive, but also has a harsh working environment, which is harmful to the physical and mental health of workers. In order to protect the environment, a large amount of crop straw also needs to be processed. Forage and various crop straws need to be unbundled before processing. At present, there is no relevant machinery at home and abroad to replace manual unbundling, which seriously affects the processing efficiency of forage and the harmless treatment of various crop straws.

[0003] Therefore, this utility model provides an automatic straw bale correction, unbundling, and rope-pulling machine to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses an automatic straw bag correction, unbundling and rope-pulling machine. The technical solution adopted includes a correction conveying mechanism, an automatic rope cutting mechanism and an automatic rope pulling mechanism. The correction conveying mechanism includes two parts: parallel correction and correction conveying, which are installed on an inclined conveyor. The automatic rope cutting mechanism is connected to the right side of the correction conveying mechanism. The automatic rope cutting mechanism consists of a rope cutting motor installed on the lower left side of the middle of the horizontal conveyor and a blade installed on the output shaft of the rope cutting motor. The automatic rope pulling mechanism is installed on the upper right side of the automatic rope cutting mechanism.

[0005] As a preferred embodiment of this utility model, the parallel correction part includes a first sensor installed on the front and rear sides of the conveyor. U-shaped fixing ears are symmetrically arranged on the front and rear sides of the conveyor to the right of the first sensors. The front and rear U-shaped fixing ears are respectively hinged to the middle of the vertical part of the L-shaped lever. The lower slots of the vertical parts of the front and rear L-shaped levers are respectively hinged to the ends of the telescopic shafts of the first cylinder installed at the bottom of the conveyor. The first cylinder is controlled by PLC to push the L-shaped lever to stop the front side of the bale from moving forward. When the two sides of the bale are parallel, the first cylinder retracts and the bale moves forward in parallel.

[0006] As a preferred embodiment of this utility model, the correction conveying section includes a second sensor installed on the right side of the parallel correction section, which is arranged opposite to the front and rear of the conveyor belt. L-shaped clamping arms are symmetrically arranged on the front and rear sides of the conveyor to the right of the second sensors. The upper opposite ends of the front and rear L-shaped clamping arms are fixedly connected to clamping plates, and the lower opposite sides of the front and rear L-shaped clamping arms are respectively fixedly connected to the telescopic shafts of the second cylinders installed opposite to each other on the lower part of the conveyor belt. The function of the correction conveying section is that after the second sensors on both sides of the conveyor detect that the bales have passed the second sensors, the corrected parallel bales are positioned in the middle of the conveyor by the second cylinders controlled by the PLC, so that they are concentric with the conveyor and smoothly enter the rope cutting and rope pulling area on the right side.

[0007] In a preferred embodiment of this utility model, the automatic rope-drawing mechanism includes an automatic lifting frame. Hydraulic cylinders controlling the vertical movement of the automatic lifting frame are installed in the front and rear columns. Mounting blocks are symmetrically arranged on opposite sides of the upper part of the front and rear side walls of the automatic lifting frame. Rotary wheel bearing chambers are respectively installed on the front and rear mounting blocks. Rotary wheel shafts are rotatably inserted into the bearing chambers. The front end of each rotary wheel shaft is connected to the output shaft of a drive motor via a reducer. Opposite rotary wheels are fixedly fitted in the middle of each rotary wheel shaft. The edges of the opposite sides of the rotary wheels... A circular array of robotic arm spindles is arranged in rotation. The two ends of each robotic arm spindle are respectively inserted into the rotating wheel via bearings. Rope pickers are symmetrically arranged on the front and rear sides of each robotic arm spindle. A gear is fixedly mounted on the robotic arm spindle in front of the rope picker. The edge of the gear facing the center of the rotating wheel meshes with the teeth of a rack. One end of the rack is fixedly connected to the telescopic shaft of a miniature cylinder mounted on the rotating wheel. An L-shaped fixing rod is fixedly connected to the middle of the left side of the automatic lifting frame. A height detection sensor is fixedly installed at the lower end of the vertical arm of the L-shaped fixing rod.

[0008] As a preferred embodiment of this utility model, the end of the rope picker is a pointed steel spike that extends below the front of the rotating wheel. This design of the rope picker makes it easy for the controller to rotate at a certain angle so that when it rotates to the lowest position, the rotating wheel is unscrewed, inserted into the inside of the hay bale, and the rope cut at the bottom is picked up.

[0009] In a preferred embodiment of this utility model, the lower end of the height detection sensor is higher than the lowest edge of the rotating wheel; the height of the hay bale flowing under it is detected by the height detection sensor, and then fed back to the PLC signal to adjust the height of the rotating wheel so that the hay bale can just flow through the lower part of the rotating wheel, and the rope picker on the edge of the rotating wheel can just be inserted into the hay bale when it is rotated out, so that the rope is picked up as the rotating wheel rotates.

[0010] As a preferred embodiment of this utility model, L-shaped support rods are fixedly connected to the lower front and rear sides of the right side wall of the automatic lifting frame, and rope collecting guide grooves are fixedly connected to the upper ends of the front and rear L-shaped support rods. The left end opening of the rope collecting guide groove is located at the rightmost edge of the rotating wheel.

[0011] The front and rear inner walls of the automatic lifting frame, which are directly opposite the lower part of the bearing chamber of the front and rear wheel shafts, are symmetrically equipped with brackets. The upper part of the opposite side of the front and rear brackets is respectively equipped with a grass-removing motor. Several paddles are arranged in a circular array at the end of the output shaft of the grass-removing motor. The edge of the paddle is located at the lower edge of the wheel. The bottom of both brackets is fixedly equipped with rope-picking spikes.

[0012] The beneficial effects of this utility model are as follows: By setting up a correction and conveying mechanism, an automatic rope cutting mechanism, and an automatic rope pulling mechanism, the entire process of unbundling and rope pulling of straw bales is automated, which greatly improves work efficiency and reduces manual labor intensity. The first sensor and the first cylinder of the parallel correction part work together with an L-shaped lever, and the second sensor and the second cylinder of the correction and conveying part work together with an L-shaped clamping arm to ensure that the straw bales are transported parallel and centered, avoiding process failures caused by skewing. The height detection sensor of the automatic rope pulling mechanism, together with the hydraulic cylinder, can adaptively adjust the height of the rotating wheel. The rope picker with sharp steel spikes can accurately insert into the straw bale to pick up broken ropes. The rope collecting guide groove realizes the orderly collection of ropes. The overall equipment operates stably and has strong adaptability, effectively ensuring the accuracy and continuity of rope cutting and rope pulling. Attached Figure Description

The automatic rope cutting mechanism 2 consists of a rope cutting motor 21 installed on the lower left side of the middle of the horizontal conveyor and a blade 22 installed on the output shaft of the rope cutting motor. The horizontal conveyor is driven by a motor of a conveyor chain plate installed on the frame below it through a chain and sprocket. The automatic rope cutting mechanism 2 is mounted on the upper right side of the automatic rope pulling mechanism 3. The automatic rope pulling mechanism 3 includes an automatic lifting frame 31. Hydraulic cylinders 32 for controlling the up-and-down movement of the automatic lifting frame 31 are installed in the front and rear columns. Mounting blocks are symmetrically arranged on opposite sides of the upper front and rear side walls of the automatic lifting frame 31. Rotary wheel bearing chambers 33 are respectively installed on the front and rear mounting blocks. Rotary wheel shafts 34 are rotatably inserted into the bearing chambers 33. The front end of the rotary wheel shaft 34 is connected to the output shaft of the drive motor 35 via a reducer. Opposite rotary wheels 36 are fixedly fitted in the middle of the rotary wheel shaft 34. Several robotic arm spindles 37 are rotatably arranged in a circular array on the opposite edge of the front and rear rotary wheels 36. Both ends of the robotic arm spindles 37 are rotatably inserted into the rotary wheels 36 via bearings. Rope pickers 38 are symmetrically arranged on the front and rear sides of the robotic arm spindles 37. The end of the rope picker 38 is a sharp steel spike, extending below the front of the rotating wheel 36. A gear 39 is fixedly mounted on the main shaft of the robot arm on the front side of the rope picker 38. The edge of the gear 39 facing the center of the rotating wheel meshes with the teeth of the rack 310. One end of the rack 310 is fixedly connected to the telescopic shaft of the miniature cylinder 311 mounted on the rotating wheel. An L-shaped fixing rod 312 is fixedly connected to the middle of the left side of the automatic lifting frame 31. A height detection sensor 313 is fixedly installed at the lower end of the vertical arm of the L-shaped fixing rod 312. The lower end of the height detection sensor 313 is higher than the lowest edge of the rotating wheel 36. L-shaped support rods 314 are fixedly connected to the lower front and rear sides of the right side wall of the automatic lifting frame 31. The upper ends of the front and rear L-shaped support rods 314 are fixedly connected to the rope collecting guide groove 315.

[0017] The front and rear inner walls of the automatic lifting frame 31, which is directly opposite the lower part of the bearing chamber 33 of the front and rear wheel shafts, are symmetrically equipped with brackets 4. The upper part of the opposite side of the front and rear brackets 4 is respectively equipped with a grass-picking motor 5. Several paddles 6 are arranged in a circular array at the end of the output shaft of the grass-picking motor 5. The edge of the paddles 6 is located at the lower edge of the wheel 36. The bottom of both brackets 4 is fixedly equipped with rope-picking spikes 7. The rope-picking spikes 7 are two parallel sharp steel spikes that extend below the front of the wheel 36 and are slightly lower than the height of the grass bale. The rope-picking spikes 7 are precisely inserted below the rope cut by the bottom blade to pick up the rope and send it to the rope picker 38.

[0018] The device is controlled by a controller installed on the lower frame of the horizontal conveyor, and the controller uses a PLC as the main controller.

[0019] The working principle of this invention is as follows: First, the hay bales enter the alignment conveyor mechanism 1. After the first sensor 11 of the parallel alignment section detects the hay bale's deviation, the PLC controls the front and rear first cylinders 14 to simultaneously push the L-shaped levers 13 at the front and rear of the conveyor to extend, preventing the hay bale on the front side from advancing. Once the hay bales are parallel on both sides, the first cylinder 14 retracts, and the hay bales continue to advance. Subsequently, after the second sensor 15 of the alignment conveyor section detects the hay bale flow, the PLC controls the front and rear second cylinders 18 to drive the front and rear L-shaped levers 13. The clamping arm 16 extends the clamping plate 17 simultaneously, positioning the bale in the middle of the conveyor so that it enters the automatic rope-cutting mechanism 2 concentrically. The rope-cutting motor 21 drives the blade 22 to cut the rope at the bottom of the bale. The bale continues to be conveyed to the bottom of the automatic rope-pulling mechanism 3. The height detection sensor 313 detects the height of the bale and sends a signal to the PLC. The hydraulic cylinder 32 adjusts the height of the automatic lifting frame 31. The drive motor 35 drives the rotating shaft 34 and the rotating wheel 36 to rotate through the reducer. The micro cylinder 311 pushes the rack 310 to drive the gear 39 to rotate, causing the rope picker 38 on the main shaft 37 of the robot arm to rotate out of the rotating wheel 36 and insert into the top of the bale. The rotating wheel 36 rotates clockwise to lift the rope, while the rope-lifting spike 7 precisely inserts below the rope cut by the bottom blade to lift the rope and send it to the rope-lifting device 38. The lifted rope rotates clockwise and eventually reaches the far right of the rotating wheel 36. Since the rope-lifting device 38 is in the unscrewed state at this time, the rope falls into the rope-collecting guide groove 315 due to rotational inertia and gravity. During the above rope-lifting process, the front and rear grass-removing motors 5 rotate, driving the lower paddle 6 to rotate and remove residual weeds from the rope-lifting teeth. The unbundled grass bales continue to flow into the next process with the horizontal conveyor, realizing the continuous operation of automatic grass bale correction, rope cutting and rope extraction.
