Description

Technical Field

[0001] This invention relates to the field of baler knotters, and in particular to a knotter for a rice straw harvesting baler. Background Technology

[0002] The straw harvester and baler is the core equipment for realizing the large-scale collection, storage and transportation of straw. The knotter, as its main component, undertakes the key task of automatically knotting and shaping the compressed straw balers. The knotting jaws, as the core actuator of the knotter, need to complete a series of continuous actions such as clamping, wrapping, biting and releasing the rope. It is the key carrier for achieving the shaping of the baler knots. In actual operation, the outer contour of the eagle beak has natural sharp corners, grooves and assembly steps, and there is a narrow dead angle for rope accumulation between the rope shovel and the eagle beak. In addition, the polypropylene baler rope is prone to fuzzing and exuding fiber filaments. Combined with the dust and straw fragments in the straw working environment, the baler rope is very easy to get caught, entangled and accumulate on the outer wall of the eagle beak and at the base of the rope shovel. This rope accumulation will directly push the gap between the rope release rod and the eagle beak, offsetting the effective rope pushing stroke of the rope release rod, causing the rope release rod to fail to push the rope, and the rope loop cannot be released from the eagle beak. This leads to functional failures such as continuous empty knots and missed knots, causing the baler to lose its knotting ability and not be able to self-heal.

[0003] To restore normal operation, existing technologies require frequent shutdowns to disassemble the protective cover and manually clean the tangled ropes, resulting in a sharp drop in operating efficiency. In high humidity and complex conditions, frequent shutdowns for cleaning are necessary, significantly reducing effective operating time and disrupting the continuity of harvesting operations. Furthermore, the force of the tangled ropes can cause the rope-removing rod to bend and the beak edges to wear, compromising the precision of the mechanism. Even after cleaning the tangled ropes, the original precision cannot be restored, thus exacerbating the risk of subsequent failures. Summary of the Invention

Detailed Implementation

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a knotter for a straw harvester and baler. The knotter includes a frame 11, which supports various components. A toothed disc 12 is provided on the frame 11. A knotting jaw 13 is provided on one side of the frame 11. The knotting jaw 13 is used to rotate and knot the rope. A rope pushing rod 14 is provided on the frame 11. A rope cutting knife is fixed on one side of the rope pushing rod 14. The rope pushing rod 14 is used to push the knotted rope end away from the knotting jaw 13 and cut the rope by the rope cutting knife. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0035] Cleaning component 2, located on one side of frame 11, includes a cutting component 21. The cutting component 21 includes a support plate 211 fixed to one side of frame 11. A movable frame 212 is provided on one side of the support plate 211. The movable frame 212 is U-shaped and has an inner movable groove. A cutter 213 is provided inside the movable frame 212. The end of the cutter 213 is inclined. There are two cutters 213, located on both sides inside the movable frame 212. The cutter 213 is movably connected to the movable groove.

[0036] A connecting block 214 is fixed to one side of the cutter 213. A rotating column 215 is rotatably connected inside the movable frame 212. The rotating column 215 passes through the support plate 211 and is movably connected to the support plate 211. A first reciprocating roller 216 is fixed to one end of the rotating column 215. A first fixed shaft 217 is fixed inside the connecting block 214. The first fixed shaft 217 meshes with the first reciprocating roller 216. A fixed sleeve 218 is fixed to one side of the support plate 211. A positioning shaft 219 is fixed on the fixed sleeve 218. A sliding groove 215-1 and a spiral groove 215-2 are provided on the rotating column 215. The sliding groove 215-1 is straight and communicates with the spiral groove 215-2. The positioning shaft 219 slides in the sliding groove 215-1.

[0037] When the movable frame 212 moves towards the knotting pliers 13, the blades of the two cutters 213 will contact the rope wrapped on the knotting pliers 13. At the same time, the first fixed shaft 217 will enter the spiral groove 215-2. As the movable frame 212 moves, the rotating column 215 will drive the first reciprocating roller 216 to rotate. The first reciprocating roller 216 drives the connecting block 214 and the cutters 213 to move back and forth through the first fixed shaft 217. As the cutters 213 move, they can clean the rope wrapped on the knotting pliers 13. The rope is cut and cleaned to effectively prevent the accumulation of rope into a rigid layer, thus preventing it from supporting the gap between the rope release rod and the eagle beak. This solves the problem of rope release rod failure and rope loop failure at the root, ensuring continuous and stable operation of the knotter, greatly improving the baling rate of the baler. It also eliminates the tediousness and inconvenience of frequent manual stops for disassembly and cleaning, reduces the frequency of downtime and cleaning time, significantly improves the effective working time and overall efficiency of the baler, and avoids chain blockage and spillage problems during the harvesting process.

[0038] Example 2, refer to Figures 4-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the cleaning component 2 also includes a moving part 22. The moving part 22 includes a second reciprocating roller 221 fixed to one side of the moving frame 212. The second reciprocating roller 221 has a large pitch. The second reciprocating roller 221 passes through the support plate 211 and is movably connected to the support plate 211. A positioning sleeve 222 is rotatably connected to one side of the support plate 211. A second fixed shaft 223 is fixed inside the positioning sleeve 222. The second fixed shaft 223 meshes with the second reciprocating roller 221. When the positioning sleeve 222 rotates, it will drive the second reciprocating roller 221 to move through the second fixed shaft 223. Thus, the moving frame 212 can be driven to move towards the position of the knotting pliers 13 through the second reciprocating roller 221. After the positioning sleeve 222 rotates one revolution, the second reciprocating roller 221 will move in the opposite direction to reset.

[0040] The cleaning component 2 also includes a rotating component 23, which includes a first gear 231 rotatably connected to the outside of the positioning sleeve 222, a second gear 232 provided on one side of the first gear 231, the first gear 231 meshing with the second gear 232, a turntable 233 fixed on the outside of the positioning sleeve 222, a torsion spring 234 fixed on one side of the turntable 233, and the other end of the torsion spring 234 fixed to the first gear 231.

[0041] A rotating sleeve 235 is fixed inside the second gear 232. The rotating sleeve 235 is rotatably connected to one side of the support plate 211. A guide shaft 236 is fixed inside the rotating sleeve 235. A movable column 237 is inserted into the rotating sleeve 235. The end of the movable column 237 contacts the push rope rod 14. A guide groove 237-1 and a reset groove 237-2 are provided on the movable column 237. There are multiple guide grooves 237-1 and reset grooves 237-2, which are evenly distributed in a ring on the outside of the movable column 237. The two ends of the reset groove 237-2 are connected to two adjacent guide grooves 237-1 respectively. The guide groove 237-1 is arc-shaped, and the reset groove 237-2 is vertical.

[0042] A baffle 237-3 is provided at the connection between the guide groove 237-1 and the reset groove 237-2. A slot is provided at the connection between the guide groove 237-1 and the reset groove 237-2. The baffle 237-3 is rotatably connected to the slot via a rotating shaft, and one side is in contact with the inner wall of the slot. The baffle 237-3 can only rotate into the guide groove 237-1, but cannot rotate into the reset groove 237-2. A second torsion spring is provided on the baffle 237-3 to reset the baffle 237-3 after rotation.

[0043] When the push rod 14 pushes the rope and resets, it will push the movable column 237 to move. At this time, the guide shaft 236 will move along the guide groove 237-1 under the guidance of the baffle 237-3. Through the cooperation of the two, the rotating sleeve 235 and the second gear 232 will rotate, and the second gear 232 will drive the first gear 231 to rotate. At this time, the first gear 231 will tighten and charge the torsion spring 234. When the push rod 14 pushes the rope again, it will separate from the movable column 237. At this time, the movable column 237 will move towards the push rod 14, and the guide shaft 236 will move in the opposite direction along the reset groove 237-2 to reset and enter the next adjacent guide groove 237-1.

[0044] As the push rod 14 continues to move, the torsion spring 234 is fully charged, and the first gear 231 will lock and cannot rotate. The torsion released by the torsion spring 234 will drive the turntable 233 to rotate, thereby enabling the turntable 233 to drive the positioning sleeve 222 to rotate, and causing the moving frame 212 to drive the cutter 213 to move towards the position of the knotting pliers 13.

[0045] The movable frame 212 can only move when the push rod 14 is pushing the rope. When the push rod 14 completes the rope pushing operation and moves in the opposite direction, it will push the cutter 213 and the movable frame 212, which have completed the rope cutting, to move in the opposite direction and move them to their initial positions. At the same time, the elastic force of the torsion spring 234 will be completely released, and the torsion spring 234 can be recharged as the push rod 14 moves.

[0046] A fixing plate 238 is fixed to the outside of the movable column 237. A first spring 239 is fixed to one side of the fixing plate 238. A positioning column 230 is fixed to one side of the support plate 211. The positioning column 230 is movably connected to the fixing plate 238. The two work together to guide and position the movable column 237, preventing the movable column 237 from rotating when it moves. When the push rope rod 14 pushes the movable column 237 to move, it will compress the first spring 239 through the fixing plate 238. When the push rope rod 14 separates from the movable column 237, the first spring 239 can push the fixing plate 238 and the movable column 237 to move in the opposite direction.

[0047] Example 3, referring to Figures 6-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, the cleaning component 2 also includes a locking component 24, which includes a fixing bracket 241 fixed to one side of the support plate 211. A limiting post 242 is inserted into the fixing bracket 241. A limiting hole 233-1 is opened on the turntable 233. The limiting post 242 engages with the limiting hole 233-1. The two work together to lock the turntable 233, so that the turntable 233 will not rotate during the tightening and charging process of the torsion spring 234.

[0049] A fixing block 243 is fixed to the outside of the limiting post 242. A second spring 244 is fixed to one side of the fixing block 243. The other end of the second spring 244 is fixed to the fixing frame 241. The second spring 244 is used to apply a pushing force to the fixing block 243 and drive the limiting post 242 to engage more securely with the limiting hole 233-1 through the fixing block 243.

[0050] A positioning plate 245 is fixed to one side of the support plate 211. A stabilizing column 246 is inserted into the positioning plate 245. A pressing rod 247 is fixed to the bottom of the stabilizing column 246. The pressing rod 247 is L-shaped. A force-receiving groove 242-1 is opened on the limiting column 242. The inner wall of the force-receiving groove 242-1 is inclined. A third spring 248 is fixed to the top of the pressing rod 247. The top of the third spring 248 is fixed to the positioning plate 245. The elastic force of the third spring 248 is greater than that of the second spring 244. When the stabilizing column 246 is released from restriction, the third spring 248 will push the pressing rod 247 to move downward and press the inclined inner wall of the force-receiving groove 242-1 through the end of the pressing rod 247. Through the cooperation of the two, the limiting column 242 is moved, thereby separating the limiting column 242 from the limiting hole 233-1 and releasing the restriction on the turntable 233.

[0051] When the turntable 233 is released from its restriction and can rotate, since the first gear 231 and the second gear 232 are always in a meshing state, and the second gear 232 is restricted by the reset groove 237-2 and cannot rotate actively, the first gear 231 is also in a locked state. Thus, when the torsion spring 234 releases its elastic force, it will only drive the turntable 233 and the positioning sleeve 222 to rotate.

[0052] The cleaning component 2 also includes a limiting member 25, which includes a positioning frame 251 fixed to one side of the support plate 211. A rod 252 is provided inside the positioning frame 251. A slot 246-1 is provided on the stabilizing column 246. The rod 252 engages with the slot 246-1, and the two work together to lock the stabilizing column 246, preventing it from moving downward. A fourth spring 253 is fixed to one end of the rod 252, and the other end of the fourth spring 253 is fixed to the inner wall of the positioning frame 251. The fourth spring 253 is used to apply a pushing force to the rod 252, making the engagement between the rod 252 and the slot 246-1 more secure.

[0053] The cleaning component 2 also includes a pusher 26, which includes a push rod 261 inserted into the positioning frame 251. The push rod 261 is L-shaped. A stabilizing frame is fixed to one side of the support plate 211. The push rod 261 is movably connected to the stabilizing frame. A positioning groove 252-1 is provided on the insertion rod 252. The inner wall of the positioning groove 252-1 is inclined. A fixing rod 262 is fixed to one side of the second gear 232. The end of the fixing rod 262 is inclined. When the second gear 232 rotates one revolution and tightens and charges the torsion spring 234, it will drive the end of the fixing rod 262 to contact the push rod 261 and push the push rod 261 to move. This allows the push rod 261 to press against the inclined inner wall of the positioning groove 252-1. Through the cooperation of the two, the insertion rod 252 is moved and separated from the slot 246-1, thereby releasing the restriction on the stabilizing column 246.

[0054] A force-bearing frame 263 is fixed to the top of the stabilizing column 246. A moving rod 264 is inserted into the support plate 211. The moving rod 264 is L-shaped, with one end passing through the support plate 211 and fixed to the second reciprocating roller 221. A pressing block 265 is hinged to the end of the moving rod 264. A third torsion spring is provided on the hinge seat for hinged pressing block 265 to keep pressing block 265 in a vertical state. One side of pressing block 265 is inclined. A stop block 266 is fixed on one side of pressing block 265 and at the top of moving rod 264. The stop block 266 is used to restrict pressing block 265 to tilt in only one direction.

[0055] When the second reciprocating roller 221 drives the moving frame 212 to move toward the knotting jaw 13, it will drive the extrusion block 265 to move through the moving rod 264. At this time, the straight side of the extrusion block 265 will contact the force frame 263 and tilt due to the reverse thrust of the force frame 263. Therefore, it will not hinder the movement of the extrusion block 265. When the second reciprocating roller 221 moves in the reverse direction to reset, the inclined side of the extrusion block 265 will contact the force frame 263. The extrusion block 265 will be unable to tilt due to the positioning obstruction of the stop block 266. Therefore, it will apply a thrust to the inner wall of the force frame 263 and cause the force frame 263 to drive the stabilizing column 246 to move upward. At this time, the insertion rod 252 will engage with the slot 246-1 again and lock the stabilizing column 246. The limiting column 242 will be inserted into the limiting hole 233-1 again and lock the turntable 233.

[0056] When the push rod 14 pushes the rope and resets, it will push the movable column 237 to move. At this time, the guide shaft 236 will move along the guide groove 237-1 under the guidance of the baffle 237-3. The two work together to drive the rotating sleeve 235 and the second gear 232 to rotate. The second gear 232 drives the first gear 231 to rotate. At this time, the first gear 231 will tighten and charge the torsion spring 234. When the second gear 232 rotates one revolution and tightens and charges the torsion spring 234, it will drive the end of the fixed rod 262 to contact the push rod 261 and push the push rod 261 to move. This allows the push rod 261 to press against the inclined surface of the inner wall of the positioning groove 252-1. The two work together to drive the insertion rod 252 to move and separate the insertion rod 252 from the slot 246-1, thereby releasing the restriction on the stabilizing column 246.

[0057] When the stabilizing column 246 is released from its restriction, the third spring 248 will push the pressing rod 247 downward and press the inclined surface of the inner wall of the force groove 242-1 through the end of the pressing rod 247. The two work together to drive the limiting column 242 to move, thereby separating the limiting column 242 from the limiting hole 233-1 and releasing the restriction on the turntable 233. At this time, the torsion released by the torsion spring 234 will drive the turntable 233 to rotate, and the turntable 233 will drive the positioning sleeve 222 to rotate.

[0058] When the positioning sleeve 222 rotates, it drives the second reciprocating roller 221 to move via the second fixed shaft 223. This, in turn, drives the moving frame 212 towards the knotting pliers 13. As the moving frame 212 moves towards the knotting pliers 13, the blades of the two cutters 213 come into contact with the rope wound on the knotting pliers 13. Simultaneously, the first fixed shaft 217 enters the spiral groove 215-2. With the movement of the moving frame 212, the rotating column 215 drives the first reciprocating roller 216 to rotate. The first reciprocating roller 216, via the first fixed shaft 217, drives the connecting block 21. 4. The cutter 213 moves back and forth. As the cutter 213 moves, it can cut and clean the rope wrapped on the knotting jaws 13, thereby effectively preventing the rope from accumulating and forming a rigid accumulation layer. This prevents the rope from supporting the gap between the rope release rod and the beak, and solves the problem of rope release rod failure and rope loop failure from the root. This ensures continuous and stable operation of the knotter, greatly improves the baling rate of the baler, and eliminates the tediousness and inconvenience of frequent manual stops for disassembly and cleaning. It also reduces the frequency of machine stops and cleaning time, significantly improves the effective working time and overall operating efficiency of the baler, and avoids chain blockage and spillage problems in the harvesting process.
