Description

[0001] The present application relates to the technical field of straw bundling, in particular to a discharging and compacting device of a bundling machine. BACKGROUND

[0002] The bundling machine is a kind of agricultural machinery and equipment for compacting and packaging of crop straw, forage and other materials after harvesting, which is widely used in straw returning to field, feed storage and transportation, and utilization of crop waste resources.

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0044] REFERENCE Figures 1-10 The present embodiment provides a baling machine discharging and compacting device, which mainly comprises a baling support 100, a conveying belt component, a shaping clamp jaw 101, a compression ring 102, a compression plate 103, a baling device 104 and a folding component.

[0045] The baling support 100 is a frame structure, used for bearing multiple functional components of the compacting device. The inside of the baling support 100 is provided with the conveying belt component, used for orderly conveying the collected straw materials to the compacting and baling area according to the direction.

[0046] The shaping clamp jaw 101 is provided in two, symmetrically arranged inside the baling support 100. The two shaping clamp jaws 101 can rotate around the installation axis thereof, used for preliminarily folding the straw materials after the conveying belt component sends the materials to the predetermined position, so as to change the straw materials from the loose and accumulated state to the compact and concentrated state, which is beneficial to subsequent compacting.

[0047] The folding component is arranged between the baling support 100 and the shaping clamp jaw 101, used for driving the two shaping clamp jaws 101 to perform the rotating action. After the preliminary folding is completed, the folding component continues to act to move the compression ring 102 arranged on both sides of the baling support 100. The compression ring 102 is inserted from the outside to the inside, respectively inserted into both ends of the material column, providing structural preparation for the compacting ring embrace.

[0048] Each of the compression rings 102 is internally provided with a plurality of compression plates 103, which are arc-shaped and distributed along the circumferential direction of the compression ring 102 and are slidably arranged in the compression ring 102. After the compression ring 102 is inserted in place, the folding member further controls the compression plates 103 to slide inward, so that the plurality of arc-shaped compression plates 103 are gradually folded, and finally form a ring-shaped closed structure, to exert radial pressure on the outer periphery of the material, thereby realizing the compaction operation and improving the density and shape stability of the bale.

[0049] The bundling devices 104 are respectively arranged on both sides of the bundling support 100, and are used for bundling the material in the compacted state. The bundling device 104 can adopt a mature mechanical bundling structure, such as hot melt bonding or mechanical knotting type. The bundling device 104 internally includes a bundling head, a belt disc mechanism, a tensioning mechanism and other conventional components, and can complete a series of bundling operations such as conveying, winding, tensioning, cutting and sealing of the bundling belt. The bottom of the bundling device 104 is provided with a base, which is slidably connected with the bundling support 100, so that the bundling device 104 can be moved to the material compression part by the staff after the compaction work is completed, to perform the bundling work.

[0050] In the working process of the bale output compaction device provided in the embodiment, the straw material collected is first conveyed along a set path to the compaction station in the bundling support 100 by the conveying belt member.

[0051] When the straw material reaches the designated position, the two symmetrical shaping clamps 101 arranged in the bundling support 100 rotate around the installation axis thereof under the driving of the folding member, and approach and clamp the two sides of the material, so that the loose straw material is preliminarily formed into a columnar structure. Through the pre-folding process, the spatial divergence of the material can be effectively reduced, so that the material has a certain compactness and directionality, to create conditions for the next compression and improve the precondition for compaction and forming.

[0052] Subsequently, the folding member continues to act, and drives the compression rings 102 arranged on both sides of the bundling support 100 to move along the guide path to the material. The compression rings 102 are respectively inserted into the material column from both ends thereof, to complete the positioning and surrounding of the end portions of the material. The introduction of the ring-shaped structure has good shaping support effect, to ensure the uniformity of stress and the symmetry of forming in the subsequent compression process.

[0053] After the compression ring 102 is inserted in place, the folding member further drives the plurality of compression plates 103 inside the compression ring 102 to slide synchronously inward in the radial direction. The compression plates 103 are arc-shaped structures uniformly arranged along the circumference of the compression ring 102, gradually forming a closed ring during the central folding process, and contacting the outer periphery of the material to apply radial pressure. This action achieves overall ring compression of the straw cylinder, significantly improves the compaction density, effectively suppresses the generation of local voids, and enhances the structural strength and transportation stability of the bale.

[0054] After compaction is completed, the bundling device 104 located on both sides of the bundling support 100 begins to perform the bundling operation. The bottom of each bundling device 104 is provided with a slidable base structure, which is slidingly connected with the bundling support 100, facilitating the staff or the additional driving device to push it to a position close to the compression area. At this time, the bundling device 104 starts its internal bundling head, tensioning mechanism and belt disc mechanism, sends out the bundling belt and forms a closed loop around the compacted material, and completes the sealing of the belt by hot melting or knotting. This step ensures that the bale still maintains the formed structure after being separated from the device, facilitating subsequent handling, stacking and storage.

[0055] In the present embodiment, the conveying belt member includes a conveying support 200 connected to the ground inside the bundling support 100, which is used to carry the conveying mechanism and provide a stable support base. A plurality of rollers 201 are rotatably connected to the conveying support 200, which are arranged at intervals along the conveying direction. A transmission belt 202 is commonly sleeved on the plurality of rollers 201, which is used to realize the conveying action of the straw material.

[0056] The conveying support 200 is also connected with a driving motor 203, the driving shaft of which is connected with one of the rollers 201 through a shaft coupling. When the motor 203 is powered on, it drives the roller 201 to rotate, and in turn drives the transmission belt 202 to make a circular motion, completing the stable conveying of the material on the conveying path. In the present embodiment, the conveying belt member has two, and a predetermined interval is reserved between the two conveying belt members, which is used to leave a working space for the shaping clamping jaw 101, ensuring that the subsequent compaction and bundling links can be smoothly inserted and act on the material body.

[0057] In the present embodiment, the folding member includes a gear a300 provided on the shaping clamping jaw 101, which is rigidly fixed with the shaping clamping jaw 101 and can drive the shaping clamping jaw 101 to make a rotary motion. The bundling support 100 is slidingly connected with a rack a301, which is engaged with the gear a300. When the rack a301 slides in a certain direction, the gear-rack engagement transmission structure is realized to drive the angle of the shaping clamping jaw 101.

[0058] Through the above setting, in the working process, when the straw material delivered to the site needs to be preliminarily gathered, the rack a301 provided on the bundling support 100 slides under the action of external force. Since the rack a301 is engaged with the gear a300 on the shaping clamp jaw 101, the linear motion of the rack a301 is converted into the rotary motion of the gear a300, thereby driving the shaping clamp jaw 101 to rotate towards the material direction with the respective mounting shaft as the center, completing clamping and gathering.

[0059] In the embodiment, the shaping clamp jaw 101 comprises a rotating shaft 302 rotatably connected to the bundling support 100, which is the rotating core of the shaping clamp jaw 101 and is arranged transversely along the material conveying direction. The rotating shaft 302 is provided with three arc-shaped strips 303, one of which in the middle is fixedly connected to the rotating shaft 302 and rotates with the rotating shaft 302 and is inserted into the gap between the two conveying belt components, and the other two arc-shaped strips 303 are slidably connected to the rotating shaft 302 and are connected to the rotating shaft 302 through springs a304, forming a flexible limiting structure.

[0060] The gear a300 is fixedly mounted on the rotating shaft 302 and can drive the entire rotating shaft 302 to rotate through engagement with the aforementioned rack a301, thereby realizing the whole participation of the three arc-shaped strips 303 in the clamping action. When the rotating shaft 302 rotates to a predetermined angle under the drive of the gear, the arc-shaped strip 303 in the middle is in the gap between the two conveying belt components, and the other two slidable arc-shaped strips 303 are automatically unfolded to the outside of the two conveying belt components, forming a left and right surrounding situation, thereby forming a three-dimensional clamping structure, effectively gathering the material on the conveying belt.

[0061] Through the above setting, in the working process of the bundling device, when the straw material is conveyed to the compacting area between the two conveying belt components, the rotating shaft 302 of the shaping clamp jaw 101 in the bundling support 100 starts to rotate under the drive of the rack a301 and the gear a300. With the rotation of the rotating shaft 302:

[0062] The arc-shaped strip 303 in the middle directly rotates with the rotating shaft 302 and is inserted into the gap area between the two conveying belt components, deeply into the material pile to form a central positioning support;

[0063] The two slidable arc-shaped strips 303 on the sides are on the two sides of the two conveying belt components after rotation, forming a three-sided surrounding clamping situation with the arc-shaped strip 303 in the middle, completing the preliminary gathering and shaping of the material.

[0064] The structure arrangement inserts the fixed arc-shaped strip 303 into the original gap between the conveying belts, realizes structure nesting and barrier-free arrangement, effectively adapts to materials of different volumes and distribution states, ensures uniform and stable gathering process, and prevents clamping deviation or loosening.

[0065] In addition, since the subsequent need to be inserted into the outer periphery of the material by the compression ring 102, if the three arc-shaped strips 303 are rigidly expanded, it will block the action of the compression ring 102. Therefore, in the design, the two arc-shaped strips 303 are designed as a slidable connection structure, when the compression ring 102 is inserted along the axial direction, the two arc-shaped strips 303 are automatically slid under the extrusion force of the outer wall of the compression ring 102 to form a bypass channel, providing space for the insertion of the compression ring 102, avoiding structural interference, and realizing the cooperation and compatibility between the folding mechanism of the shaping clamping jaw 101 and the compaction mechanism of the compression ring 102.

[0066] Through the setting of the bypass structure, the compression ring 102 can further approach the middle area of the material without being blocked, forming a deeper ring position, so that the action range of the compression force is closer to the center axis of the material. In this way, not only the stress difference between the end compaction and the middle compaction is reduced, but also the whole material is uniformly stressed in the circumferential and radial directions, which significantly improves the compaction density and the overall tightness of the bale.

[0067] In the embodiment, the folding component further includes a top platform 305 connected to the top of the bundling support 100, which is a rigid installation structure for installing a driving oil cylinder 306 and providing vertical bearing capacity. The oil cylinder 306 is fixedly installed on the top platform 305, the extension shaft of the oil cylinder 306 extends downward from top to bottom, a connecting shaft 307 is installed at the lower end of the extension shaft of the oil cylinder 306, and the connecting shaft 307 and the rack a 301 are in sliding connection, and a spring b 308 is arranged between the connecting shaft 307 and the rack a 301.

[0068] Through the above setting, during the work process, the oil cylinder 306 arranged on the top platform 305 starts to act after being powered on, and the extension shaft thereof is vertically contracted, driving the connecting shaft 307 to move upward. Since the connecting shaft 307 and the rack a 301 are in sliding connection and connected through the spring b 308, the movement is gradually transmitted to the rack a 301, realizing the sliding of the rack a 301 in the vertical direction, thereby driving the gear a 300 engaged therewith to rotate, and further realizing the rotating action of the shaping clamping jaw 101.

[0069] During the folding process, the spring b 308 plays an important role in flexible buffering. When the extension shaft of the oil cylinder 306 moves upward, the rack a 301 slides upward in the vertical direction under the force, thereby driving the shaping clamping jaw 101 to rotate and fold the straw material. Since the straw itself has a certain volume elasticity and irregularity, if the driving system is a completely rigid structure, it is easy to cause over-tightening, damage to the material or deformation in the late folding period.

[0070] To this end, the spring b308 provided in the embodiment can be elastically deformed after the rack a301 is subjected to a certain threshold of resistance or clamping force, absorbing part of the driving force, so as to avoid the direct rigid application of the folding force to the material. In this way, on the one hand, the impact of the folding end can be slowed down, and the clamping jaw can be prevented from being excessively clamped and crushed.

[0071] In the embodiment, the folding component further comprises a lead screw 400 rotatably connected to the conveying bracket 200, which is arranged along the material conveying direction, and the outer thread of the lead screw 400 is threadedly connected with the compression ring 102 for driving the compression ring 102 to move axially, so as to realize the plug-in surrounding of the two ends of the material.

[0072] In order to realize the linkage driving of the lead screw 400, the rack a301 is rotatably connected with a connecting rod a401, the connecting shaft 307 is rotatably connected with a connecting rod b402, the connecting rod b402 is fixedly provided with an extension shaft 403, and the other end of the connecting rod a401 is rotatably connected with the extension shaft 403, forming a four-bar linkage structure. A connecting sleeve 404 is arranged between the rack a301 and the connecting shaft 307, which is used for transmitting displacement and providing guiding support for the internal structure.

[0073] The connecting sleeve 404 is provided with a sliding groove 405 in the horizontal direction, and the extension shaft 403 is arranged in the sliding groove 405, so that the connecting rod drives the extension shaft 403 to slide in the sliding groove 405 when the connecting rod moves, and a horizontal limiting structure for the connecting sleeve 404 is formed.

[0074] The connecting sleeve 404 is slidably connected with a push rod 406, one end of the push rod 406 is rotatably connected with the extension shaft 403 through the rotating shaft 302, and the other end of the push rod 406 is abutted with a push plate 407 arranged on the bundling bracket 100.

[0075] The push plate 407 is slidably connected with the bracket, and a spring c408 is arranged between the push plate 407 and the bracket, which is used for providing push force buffering and return function. The push plate 407 is provided with a rack b409, and the lead screw 400 is provided with a gear b410 engaged with the rack b409, which is used for realizing the conversion of the displacement of the push plate 407 to the rotation of the lead screw 400.

[0076] Through the above setting, in the working process, when the top oil cylinder 306 drives the connecting shaft 307 to move up, and the rack a301 moves up through the potential energy of the spring b308, to rotate the shaping clamping jaw 101 to gather the material. After the shaping clamping jaw 101 completes the gathering action, the rack a301 moves up to the limit position, the connecting shaft 307 still moves up under the continuous driving of the oil cylinder 306, at this time the spring b308 is further stretched, and the connecting shaft 307 generates an upward displacement relative to the rack a301. The relative displacement can make the extension shaft 403 generate displacement through the swing of the connecting rod a401 and the connecting rod b402, and the displacement is transmitted to the push rod 406 in the sleeve 404, so that the push rod 406 in the sleeve 404 moves forward under the sliding guide action, and pushes the push plate 407 to slide.

[0077] The push plate 407 moves in the direction of the bundling support 100 under the action of the pushing force, drives the rack b409 on the push plate 407 to mesh with the gear b410 on the lead screw 400, and drives the lead screw 400 to rotate through the gear b410. Since the compression ring 102 is screwed on the outer wall of the lead screw 400, the lead screw 400 rotates at the same time and pushes the compression ring 102 forward along the axial direction, so that the compression ring 102 gradually inserts into the gathered material at both ends. When the compression ring 102 is inserted to the predetermined position, the plurality of compression plates 103 in the compression ring 102 can slide radially inward under subsequent control to apply ring pressure to the outer periphery of the material, and the compaction and shaping are completed.

[0078] In the present application, the rack a301 and the clamping jaw mechanism constitute a first action cascade unit, and its upward movement process is terminated by mechanical limiting or physical limitation of the fully closed angle of the clamping jaw. The relative displacement generated by the continued upward movement of the connecting shaft 307 triggers the action of the connecting rod structure, the sliding of the push rod 406 in the sleeve, and further drives the second action unit, the compression mechanism, to start execution. Since the gathering action of the clamping jaw is driven by the rack a301, is driven by the connecting shaft 307 and is adjusted by the tension of the spring b308, the maximum gathering degree is determined by the material size and the rack limiting.

[0079] When the clamping jaw clamps large-size material, it reaches the closed angle in advance, the upward stroke of the rack a301 is shorter, and the connecting shaft 307 will generate a larger remaining upward stroke for driving the compression process; when the clamping jaw clamps small-size or flexible material, the rack a301 can continue to move up for a longer stroke, and the relative displacement (for compression linkage) generated by the connecting shaft 307 is correspondingly reduced. Under this mechanism, the entire structure can automatically determine whether the subsequent action occurs and how much the action occurs according to the actual material state, so as to realize self-adjustment of the compression action amplitude under different material sizes, and to adapt to the material with a certain compression deformation, without damaging the material due to insufficient clamping or excessive compaction.

[0080] In the embodiment, the compression ring 102 is internally provided with a plurality of radially slidable compression plates 103. In order to realize synchronous linkage of compression action, a plurality of gear wheels c500 are rotationally connected to the inner wall of the compression ring 102. The compression plates 103 are fixedly connected with the gear racks c502 through connecting strips 501. The gear racks c502 are arranged along the radial direction and are meshingly arranged with the corresponding gear wheels c500.

[0081] The gear wheels c500 are linkage-connected through gear wheels d503, realizing linkage transmission between the plurality of gear wheels c500. Further, in order to realize conversion of driving direction, the gear wheels d503 are further meshingly connected through a transfer gear wheel e504. The gear wheel e504 is installed at a lower position of the internal structure of the compression ring 102, can transmit the input rotary action to the gear wheels d503, and finally linkage-connects all the compression plates 103.

[0082] During operation, when the compression ring 102 is driven to be inserted into the outer periphery of the columnar material and reaches a preset position, the rotary gear wheel e504 is rotated. The gear wheel e504 is meshingly connected with the gear wheels d503 as a main gear wheel, can transmit the rotary action to the gear wheels d503, the gear wheels d503 are meshed with the plurality of gear wheels c500, thereby driving the plurality of gear wheels c500 to synchronously rotate, and finally realizing the meshing action between the gear wheels c500 and the gear racks c502, so that the gear racks c502 slide along the radial direction of the compression ring 102, thereby pushing the connecting strips 501 and the compression plates 103 to slide along the radial direction and approach each other, and forming a ring-shaped compression on the outer periphery of the columnar material.

[0083] In the embodiment, in order to further realize linkage driving of the compression plates 103, a spline sleeve 505 is rotationally connected to the conveying support 200. The spline shaft 506 is slidably connected inside the spline sleeve 505, that is, the spline shaft 506 can move along the axial direction while realizing rotary action in the spline sleeve 505. A spring d507 is arranged between the spline shaft 506 and the spline sleeve 505, for providing a return elastic force after compression is completed, and maintaining the initial state. The spline sleeve 505 is connected with the lead screw 400 through a chain transmission mechanism 508. When the lead screw 400 rotates, the spline sleeve 505 can be driven to synchronously rotate.

[0084] One side of the gear wheel e504 is fixedly connected with a connecting rod 509. The end of the connecting rod 509 is respectively provided with an embedded plate 510 structure with the end of the spline shaft 506. When the compression ring 102 moves to a predetermined position, the two embedded plates 510 are in contact and meshing, so that the gear wheel e504 can also be rotated.

[0085] Through the above setting, in the working process, when the push plate 407 driving gear b410 rotates, the lead screw 400 rotates, the lead screw 400 drives the spline sleeve 505 to rotate synchronously through the chain transmission; since the spline shaft 506 and the spline sleeve 505 are connected in sliding mode, the spline shaft 506 is allowed to have certain axial extension displacement during rotation, which is particularly crucial in the subsequent compression linkage.

[0086] When the compression ring 102 is inserted into the material periphery, the connecting rod 509 on the side of the gear e504 slowly approaches the spline shaft 506 while the lead screw 400 continues to rotate to make the compression ring 102 advance. The structure design of the embedded plate 510 arranged on the connecting rod 509 and the spline shaft 506 end part respectively makes the two naturally engage when the compression ring 102 moves to the predetermined position, forming mechanical closed transmission of rotary force.

[0087] In this embedded state, the rotary action carried by the spline shaft 506 is transmitted to the gear e504, and then the gear d503 and the gear c500 are driven to rotate synchronously, so that all the racks c502 meshed with the gear c500 move inward along the radial direction, pushing the compression plate 103 to radially embrace and compress the material, thereby completing the compression action.

[0088] Through the combination of chain+spline shaft 506+embedded plate 510+gear transmission, the compression plate 103 starts to act only after the insertion of the compression ring 102 is completed, ensuring the accuracy of the compression position. The spline shaft 506 is connected with the spline sleeve 505 in sliding mode, and is matched with the spring d507 to provide a buffer space, so that the compression linkage has certain flexible compensation capability and can adapt to the stroke of different compression rings 102.

[0089] In the embodiment, the connecting rod 509 is rotatably arranged in the inner hole of the gear e504; the inner wall of the gear e504 is provided with a plurality of wedge-shaped grooves 600 in the circumferential direction; the connecting rod 509 is slidably connected with a wedge-shaped strip 601 matched with the wedge-shaped grooves 600, and the wedge-shaped strip 601 can advance and retreat along the radial direction of the connecting rod 509; the spring e602 is connected between the wedge-shaped strip 601 and the connecting rod 509, and is used to outwardly push the wedge-shaped strip 601 to make it clamped into the wedge-shaped groove 600 when it is static / light load. Thus, a wedge-shaped follow-up mechanism which can automatically engage / disengage is formed between the connecting rod 509 and the gear e504.

[0090] Through the above setting, when the compression ring 102 is inserted into position and ready to be compacted, the connecting rod 509 is continuously rotated by the upstream transmission chain structure. Under the pre-tightening action of the spring e602, the wedge-shaped strip 601 can be reliably clamped in the wedge-shaped groove 600 on the inner wall of the gear e504, so that a rigid follow-up relationship is formed between the connecting rod 509 and the gear e504.

[0091] The rotating movement of the connecting rod 509 is directly transmitted to the gear e 504, which in turn drives the gear d 503 and the gear c 500 to rotate synchronously, so that the rack c 502 slides radially and drives the plurality of pressing plates 103 to advance inward, thereby gradually applying a circumferential pressing force to the outer periphery of the material to complete the compaction and shaping action.

[0092] As the compaction process advances, when the pressing plates 103 contact and sufficiently compact the material, the rebound force or resistance of the material rapidly increases, at which time the counter-torque of the gear transmission system suddenly rises. If forced compaction continues, not only is it easy to cause the pressing plates 103 to deform and the mechanism to jam, but it can also cause overpressure damage to the material.

[0093] The present application realizes automatic disengagement and overload protection through the torque-limiting follow-up structure composed of the wedge-shaped strip 601 + wedge-shaped groove 600 + spring e 602: when the counter-torque exceeds the set threshold, the wedge-shaped strip 601 is forced to retreat along the inclined surface of the wedge-shaped groove 600, the spring e 602 is compressed and deformed, the wedge-shaped strip 601 is disengaged from the wedge-shaped groove 600, and the rigid linkage between the connecting rod 509 and the gear e 504 is released, so that the connecting rod 509 rotates to idle, the gear e 504 stops rotating, and the rack c 502 and the pressing plates 103 remain in the current position and do not retract.

[0094] In this way, on the one hand, the stroke of the pressing plates 103 is self-adaptively adjusted, which automatically matches the compaction termination position according to the size, density, elasticity and other characteristics of different materials; on the other hand, a flexible protection mechanism for the mechanical structure is also realized, which effectively avoids damage to the compaction mechanism due to overload and improves the overall reliability and adaptability.

[0095] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
