Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a netting device and a baler. Background Technology

[0002] After harvesting crops, a lot of straw is usually scattered in the fields. In response to the call for environmental protection, balers have emerged. Balers compress loose straw into tight, neat bales and tie them with ropes or nets, thereby greatly reducing the volume of straw and facilitating subsequent handling, stacking, storage and transportation.

[0003] A baler includes a wire wrapping device that delivers the wire wrapping net to the compression chamber. The compression chamber comprises a front compression chamber and a rear compression chamber rotatably connected. The wire wrapping device typically includes a wire feeding module and a wire cutting module. The wire feeding module conveys the wire wrapping net, and after conveying a set length of net, the wire cutting module cuts the net to form a bale. Initially, the front and rear compression chambers are engaged. Straw is fed into the compression chamber and rolled into a bale by the roller compression mechanism within the chamber. The wire wrapping net covers the outside of the bale to form a bale. When the diameter of the bale is larger than the diameter of the compression chamber, the bale pushes up the rear compression chamber, causing it to rotate and create an opening between the rear and front compression chambers, allowing the bale to exit the compression chamber through this opening.

[0004] A baling module typically includes a baler and a reset mechanism. The reset mechanism is used to restore the baler to its initial position. In the prior art, the reset mechanism can only reset the baler after the rear compression chamber has rotated to a certain angle. That is, after the bale is sent out of the compression chamber, the reset mechanism cannot immediately reset the baler. It needs to wait for the rear compression chamber to continue to rotate to a certain angle before the reset mechanism can start to reset the baler. This process takes a long time and affects the baling efficiency of straw. Summary of the Invention

[0005] Therefore, it is necessary to provide a wire wrapping device and a baler to address the issue of the wire cutting knife resetting affecting baling efficiency.

[0006] A net-wrapping device, comprising:

[0007] Mounting rack;

[0008] A net feeding mechanism and a net roll, the net roll being wound to form the net roll, the free end of the net roll being led out to the net feeding mechanism, the net feeding mechanism being configured to convey the net roll downstream;

[0009] A netting cutting device includes a cutting mechanism and a reset assembly. The cutting mechanism is rotatably connected to the mounting frame. The cutting mechanism has a first state and a second state. In the first state, the cutting mechanism is away from the netting. In the second state, the cutting mechanism rotates towards the netting to cut the netting. The reset assembly is disposed on the side of the mounting frame away from the cutting mechanism, and one end of the reset assembly is connected to the cutting mechanism. The reset assembly is configured to drive the cutting mechanism to rotate away from the netting, so that the cutting mechanism switches from the second state to the first state.

[0010] In one embodiment, the wire cutting device further includes:

[0011] A connecting component is disposed on the side of the mounting frame away from the cutting mechanism. The mounting frame has a sliding groove, and part of the connecting component can slide through the sliding groove. The connecting component is connected to the cutting mechanism, and one end of the reset component is connected to the connecting component. The reset component can drive the connecting component to slide along the sliding groove, so as to drive the cutting mechanism to rotate in a direction away from the grass net.

[0012] In one embodiment, the wire cutting device further includes:

[0013] A first elastic element is connected to the connecting assembly. The first elastic element is configured to drive the connecting assembly to slide along the groove, thereby driving the cutting blade to rotate toward the direction of the grass-wrapping net.

[0014] In one embodiment, the connection component includes:

[0016] The first connector has one end connected to the other end of the slide rod, and the other end of the first connector is connected to the first elastic member.

[0017] The second connector is rotatably connected at both ends to the first connector and the mounting bracket, respectively.

[0018] The third connector is rotatably connected at one end to the mounting bracket, and the reset assembly is rotatably connected to the other end of the third connector. The reset assembly is configured to drive the third connector to rotate. The rotation of the third connector can push the second connector to rotate, thereby causing the slide rod to slide along the slide groove, so as to drive the cutter mechanism to rotate away from the grass net.

[0019] In one embodiment, the cutting mechanism includes:

[0020] The blade holder assembly is rotatably connected to the mounting bracket;

[0021] A wire cutter is mounted on the blade assembly;

[0022] A rotating shaft is rotatably connected to the mounting bracket, and the blade hanger assembly can be hung on the rotating shaft and is in a transmission cooperation with the rotating shaft.

[0023] When the cutting mechanism is in the first state, the blade hanging assembly is attached to the rotating shaft and drives the rotating shaft. The rotation of the rotating shaft can drive the blade hanging assembly to move away from the rotating shaft, so that the cutting mechanism switches from the first state to the second state. The reset assembly can drive the blade hanging assembly to rotate away from the grass net and back to be attached to the rotating shaft, so that the cutting mechanism switches from the second state to the first state.

[0024] In one embodiment, the blade holder assembly includes:

[0025] The blade holder body is provided with a first meshing tooth. Along the extension direction of the first meshing tooth, the two ends of the first meshing tooth are the beginning end and the end end, respectively. The rotating shaft is provided with a second meshing tooth in the circumferential direction. The first meshing tooth and the second meshing tooth are meshed and connected. The rotation of the rotating shaft can drive the blade holder body to move along the extension direction of the first meshing tooth, so that the meshing part of the first meshing tooth and the second meshing tooth moves from the beginning end to the end end, thereby causing the blade holder body to disengage from the rotating shaft.

[0026] The mounting component is rotatably connected to the mounting bracket and is pivotally connected to the blade holder body;

[0027] A blade holder is fixedly connected to the connector, and the wire cutter is connected to the blade holder;

[0028] After the hanging knife body is detached from the rotating shaft, the mounting component rotates to drive the cutting knife to rotate in a direction closer to the grass-wrapping net.

[0029] In one embodiment, the network feeding mechanism includes:

[0030] A feeding roller is rotatably connected to the mounting frame. The feeding roller rotates to convey the straw net downstream. The feeding roller is drivenly connected to the rotating shaft.

[0031] A drive unit is configured to drive the wire feeding roller to rotate.

[0032] In one embodiment, the network feeding mechanism further includes:

[0033] Several spreading rollers are fixed to the mounting frame and distributed along the conveying path of the grass net. Along the conveying direction of the grass net, the feeding roller is located downstream of the spreading rollers, and the spreading rollers can flatten the pulled-out grass net.

[0034] In one embodiment, the network feeding mechanism further includes:

[0035] The clamping roller assembly is rotatably connected to the mounting frame, and the portion of the wire roll pulled out is clamped between the clamping roller assembly and the feeding roller.

[0036] A baler includes a frame and a netting device as described above, the netting device being mounted on the frame.

[0037] The aforementioned baling equipment can directly drive the cutting mechanism to reset via the reset component, without relying on the rotation angle of the rear compression chamber or an additional rotation process. After the cutting mechanism has finished cutting the net, it can directly act on the cutting mechanism to drive it to move away from the baling net and reset, reducing the operation time of the cutting mechanism reset and thus improving the baling efficiency of straw.

[0053] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0054] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0059] like Figures 1-4As shown, an embodiment of the present invention provides a netting device, which includes a mounting frame 1, a net feeding mechanism 2, a net roll 3, and a net cutting device. The netting 31 is wound to form a net roll 3, and the free end of the net roll 3 is pulled out to the net feeding mechanism 2, which is configured to convey the netting 31 downstream. The net cutting device includes a cutting mechanism 41 and a reset assembly 42. The cutting mechanism 41 is rotatably connected to the mounting frame 1 and has a first state and a second state. In the first state, the cutting mechanism 41 is away from the netting 31. In the second state, the cutting mechanism 41 rotates towards the netting 31 to cut the netting 31. The reset assembly 42 is disposed on the side of the mounting frame 1 away from the cutting mechanism 41, and one end of the reset assembly 42 is connected to the cutting mechanism 41. The reset assembly 42 is configured to drive the cutting mechanism 41 to rotate away from the netting 31, so that the cutting mechanism 41 switches from the second state to the first state.

[0060] The straw-winding net 31 is wound into a net roll 3. The free end of the net roll 3 is pulled out to the net-feeding mechanism 2, which conveys the straw-winding net 31 downstream in preparation for subsequent baling. Specifically, the net-feeding mechanism 2 conveys the straw-winding net 31 into the compression chamber. The cutting mechanism 41 is rotatably connected to the mounting frame 1 and has a first state and a second state. When the straw-winding net 31 is conveyed downstream for straw baling, the cutting mechanism 41 is in the first state, at which time the cutting mechanism 41 is away from the straw-winding net 31. When baling is completed... When it is necessary to cut the grass net 31, the cutting mechanism 41 switches to the second state, that is, it moves toward the grass net 31 to cut the grass net 31, thereby forming a grass bale; the reset component 42 is located on the side of the mounting frame away from the cutting mechanism 41, and one end of it is connected to the cutting mechanism 41. After the cutting mechanism 41 cuts the grass net 31, the reset component 42 directly drives the cutting mechanism 41 to move away from the grass net 31, so that the cutting mechanism 41 switches from the second state back to the first state, completing the reset, without interfering with the subsequent grass wrapping process.

[0061] Compared with related technologies, the baling device of this embodiment can directly drive the cutting mechanism 41 to reset through the reset component 42, without relying on the rotation angle of the rear compression chamber and the additional rotation process. After the cutting mechanism 41 has finished cutting the net, it can directly act on the cutting mechanism 41 to drive it to move away from the baling net 31 and reset, reducing the operation time of the cutting mechanism 41 to reset, thereby improving the baling efficiency of straw.

[0062] Optionally, such as Figure 6As shown, the net cutting device also includes a connecting component 43, which is disposed on the side of the mounting frame 1 away from the cutting mechanism 41. The mounting frame 1 has a sliding groove 11, and part of the connecting component 43 can slide through the sliding groove 11. The connecting component 43 is connected to the cutting mechanism 41, and one end of the reset component 42 is connected to the connecting component 43. The reset component 42 can drive the connecting component 43 to slide along the sliding groove 11, so as to drive the cutting mechanism 41 to rotate away from the tangled grass net 31. The groove 11 on the mounting bracket 1 provides guidance for the sliding of the connecting component 43. When the reset component 42 drives the connecting component 43 to move, the connecting component 43 can only move along the groove 11, thereby driving the cutting mechanism 41 to move accurately away from the grass wrapping net 31. This allows the cutting mechanism 41 to accurately reset to the position it was in in the first state, avoiding any deviation during the reset process. Furthermore, as an intermediate connecting component between the reset component 42 and the cutting mechanism 41, the connecting component 43 can evenly transmit the force generated by the reset component 42 to the cutting mechanism 41, improving the stability and reliability of the reset of the cutting mechanism 41.

[0063] In one alternative embodiment, such as Figure 1 , Figure 6 As shown, the reset assembly 42 includes a one-way cylinder 421 and a reset spring 422. The drive end of the one-way cylinder 421 is connected to the connecting assembly 43, and the reset spring 422 is used to drive the drive end of the one-way cylinder 421 to reset. When it is necessary to drive the cutter mechanism 41 to move away from the wrapping net 31, oil is injected into the one-way cylinder 421, causing the drive end of the one-way cylinder 421 to extend, so as to drive the cutter mechanism 41 to move away from the wrapping net 31 through the connecting assembly 43; when it is necessary to reset the one-way cylinder 421, the injection of oil into the one-way cylinder 421 is stopped, and the elastic force of the reset spring 422 pulls the drive end of the one-way cylinder 421 back to its original position, while simultaneously completing the oil draining.

[0064] Optionally, such as Figure 1 , Figure 6 As shown, the netting cutting device also includes a first elastic element 44, which is connected to the connecting assembly 43. The first elastic element 44 is configured to drive the connecting assembly 43 to slide along the slide groove 11, thereby driving the cutting mechanism 41 to rotate towards the wrapped grass netting 31. When it is necessary to cut the wrapped grass netting 31, the first elastic element 44 can quickly release energy by relying on its accumulated elastic potential energy, driving the connecting assembly 43 to slide along the slide groove 11, and then quickly driving the cutting mechanism 41 to move towards the wrapped grass netting 31, achieving timely netting cutting. Furthermore, during the process of driving the cutting mechanism 41 to move, the first elastic element 44 can continuously output elastic force to ensure that the cutting mechanism 41 can effectively cut the wrapped grass netting 31, improving the quality and reliability of netting cutting and reducing the need for secondary operations due to incomplete netting cutting.

[0065] Specifically, such as Figure 6 As shown, the connecting assembly 43 includes a slide rod 431, a first connecting member 432, a second connecting member 433, and a third connecting member 434. The slide rod 431 slides through the slide groove 11, and one end of the slide rod 431 is connected to the cutting mechanism 41. One end of the first connecting member 432 is connected to the other end of the slide rod 431, and the other end of the first connecting member 432 is connected to the first elastic member 44. The two ends of the second connecting member 433 are rotatably connected to the first connecting member 432 and the mounting bracket 1, respectively. One end of the third connecting member 434 is rotatably connected to the mounting bracket 1. The reset assembly 42 is rotatably connected to the other end of the third connecting member 434. The reset assembly 42 is configured to drive the third connecting member 434 to rotate. The rotation of the third connecting member 434 can push the second connecting member 433 to rotate, thereby causing the slide rod 431 to slide along the slide groove 11, so as to drive the cutting mechanism 41 to rotate away from the grass net 31.

[0066] When the cutting mechanism 41 needs to switch from the first state to the second state, the first elastic element 44 uses its stored elastic potential energy to pull the first connecting element 432 toward the grass net 31, which in turn pulls the sliding rod 431 to slide. Since one end of the sliding rod 431 is connected to the cutting mechanism 41, the cutting mechanism 41 moves toward the grass net 31 along with the sliding rod 431, thereby realizing the operation of cutting the grass net 31. When the cutting mechanism 41 needs to switch from the second state to the first state, the reset component 42 drives the third connecting member 434 to rotate. When the third connecting member 434 rotates, it abuts against the second connecting member 433 and pushes the second connecting member 433 to rotate. The rotation of the second connecting member 433 will drive the first connecting member 432 to move. The first connecting member 432 is connected to the slide groove 11, which in turn drives the slide rod 431 to slide along the slide groove 11, causing the slide rod 431 to move away from the wrapping net 31. This, in turn, drives the cutting mechanism 41 to move away from the wrapping net 31, so that the cutting mechanism 41 switches to the first state, that is, returns to the initial position. After the cutting mechanism 41 switches to the first state, the reset component 42 resets. At this time, the reset component 42 drives the third connecting member 434 to rotate in the opposite direction. Since the third connecting member 434 is independently rotatably connected to the mounting bracket 1, when it rotates in the opposite direction, it does not drive the second connecting member 433 and the first connecting member 432 to move. The reset component 42 itself resets to the initial position.

[0067] Optionally, such as Figure 3 , Figure 4As shown, the cutting mechanism 41 includes a blade hanging assembly 411, a cutting blade 412, and a rotating shaft 413. The blade hanging assembly 411 is rotatably connected to the mounting frame 1; the cutting blade 412 is disposed on the blade hanging assembly 411; the rotating shaft 413 is rotatably connected to the mounting frame 1, and the blade hanging assembly 411 can be hung on the rotating shaft 413 and is in a transmission cooperation with the rotating shaft 413. When the cutting mechanism 41 is in the first state, the blade hanging assembly 411 is hung on the rotating shaft 413 and is in a transmission cooperation with the rotating shaft 413. The rotation of the rotating shaft 413 can drive the blade hanging assembly 411 to move away from the rotating shaft 413, so that the cutting mechanism 41 switches from the first state to the second state. The reset assembly 42 can drive the blade hanging assembly 411 to rotate away from the grass net 31 and be hung on the rotating shaft 413, so that the cutting mechanism 41 switches from the second state to the first state.

[0068] like Figure 3 , Figure 4 As shown, when the cutting mechanism 41 is in the first state, the hanging knife assembly 411 is hung on the rotating shaft 413 and is driven by the rotating shaft 413. The cutting knife 412 is installed on the hanging knife assembly 411, and the cutting knife 412 is also in a relatively fixed state with the mounting bracket 1, waiting to perform the cutting task. When the grass-wrapped netting 31 needs to be cut, the rotating shaft 413 rotates. Due to the transmission cooperation between the blade-hanging assembly 411 and the rotating shaft 413, the rotation of the rotating shaft 413 drives the blade-hanging assembly 411 to move. As the rotating shaft 413 continues to rotate, the blade-hanging assembly 411 gradually disengages from the rotating shaft 413. After disengagement, because the blade-hanging assembly 411 is still attached to the rotating shaft 413, the blade-hanging assembly 411 and the cutting blade 412 rotate under the drive of gravity and the first elastic element 44, rotating towards the grass-wrapped netting 31. This allows the cutting blade 412 to contact the grass-wrapped netting 31 and apply cutting force to cut it. After cutting is complete, the reset assembly 42 drives the blade-hanging assembly 411 to rotate away from the grass-wrapped netting 31, returning it to its initial position and reattaching it to the rotating shaft 413, re-cooperating with the rotating shaft 413. The cutting mechanism 41 returns to its first state, ready for the next cutting operation. The rotation of the rotating shaft 413 can drive the hanging knife assembly 411 to disengage from the rotating shaft 413 so that the cutting knife 412 can cut the tangled grass net 31. The reset assembly 42 can drive the hanging knife assembly 411 to be reattached to the rotating shaft 413, realizing the rapid switching of the cutting mechanism 41 between the first state and the second state. It has high working efficiency and a relatively simple structure.

[0069] In one alternative embodiment, such as Figures 3-5As shown, the blade holder assembly 411 includes a blade holder body 4111, a mounting member 4112, and a blade holder 4113. The blade holder body 4111 is provided with a first meshing tooth 41111. Along the extension direction of the first meshing tooth 41111, the two ends of the first meshing tooth 41111 are the beginning end and the end end, respectively. The rotating shaft 413 is circumferentially provided with a second meshing tooth 4131. The first meshing tooth 41111 and the second meshing tooth 4131 are meshed and connected. The rotation of the rotating shaft 413 can drive the blade holder body 4111 along the extension direction of the first meshing tooth 41111. The movement causes the meshing portion of the first meshing tooth 41111 and the second meshing tooth 4131 to move from the beginning to the end, thereby causing the hanging knife body 4111 to disengage from the rotating shaft 413; the mounting member 4112 is rotatably connected to the mounting frame 1, and the mounting member 4112 is pivotally connected to the hanging knife body 4111; the knife holder 4113 is fixedly connected to the mounting member 4112, and the cutting knife 412 is connected to the knife holder 4113; after the hanging knife body 4111 disengages from the rotating shaft 413, the mounting member 4112 rotates to drive the cutting knife 412 to rotate in a direction closer to the wrapping net 31.

[0070] The first meshing tooth 41111 on the blade holder body 4111 meshes with the second meshing tooth 4131 circumferentially arranged on the rotating shaft 413. When the rotating shaft 413 rotates, due to the meshing of the first meshing tooth 41111 and the second meshing tooth 4131, the rotational motion of the rotating shaft 413 is converted into linear motion of the blade holder body 4111 along the extension direction of the first meshing tooth 41111. As the rotating shaft 413 continues to rotate, the meshing portion of the first meshing tooth 41111 and the second meshing tooth 4131 changes from the initial... As the blade gradually moves from end to end, when the engaging part reaches the end, the blade holder 4111 disengages from the rotating shaft 413. Since the mounting member 4112 is pivotally connected to the blade holder 4111 and rotatably connected to the mounting bracket 1, after the blade holder 4111 disengages from the rotating shaft 413, under its own weight and / or the action of the first elastic member 44, the mounting member 4112 rotates, causing the cutting blade 412 connected to the blade holder 4113 to rotate towards the direction of the wrapped grass net 31. After cutting the net, the reset assembly 42 drives the blade holder assembly 411 to rotate away from the wrapped grass net 31, so that the blade holder 4111 is reattached to the rotating shaft 413.

[0071] In one optional embodiment, the net feeding mechanism 2 includes a net feeding roller 21 and a driving member. The net feeding roller 21 is rotatably connected to the mounting frame 1. The net feeding roller 21 rotates to convey the straw-wrapping net 31 downstream. The net feeding roller 21 is drivenly connected to the rotating shaft 413. The driving member is configured to drive the net feeding roller 21 to rotate. The driving member drives the net feeding roller 21 to rotate to convey the straw-wrapping net 31 downstream, providing a mesh-like wrapping material for subsequent straw baling. Since the net feeding roller 21 is drivenly connected to the rotating shaft 413, the rotation of the net feeding roller 21 will simultaneously drive the rotating shaft 413 to rotate, thereby driving the hanging knife body 4111 to move along the extension direction of the first meshing tooth 41111. As the rotating shaft 413 continues to rotate, the meshing portion of the first meshing tooth 41111 and the second meshing tooth 4131 gradually moves from the beginning to the end. After the feed roller 21 rotates a set number of times, the length of the straw net 31 conveyed downstream is exactly the amount required for one baling. At the same time, the number of rotations of the rotating shaft 413 is also exactly such that the meshing part of the first meshing tooth 41111 of the hanging knife body 4111 and the second meshing tooth 4131 on the rotating shaft 413 moves to the end, the hanging knife body 4111 disengages from the rotating shaft 413, and the cutting knife 412 can cut the straw net 31. By connecting the feed roller 21 and the rotating shaft 413 through a transmission, the feed roller 21 and the rotating shaft 413 can be driven simultaneously by only one drive component. And when the length of the conveyed straw net 31 is exactly the amount required for one baling, the hanging knife body 4111 disengages from the rotating shaft 413 to cut the straw net 31 in time, ensuring the continuity and smoothness of the baling operation and making the feeding and cutting actions coordinated.

[0072] Specifically, such as Figure 7 As shown, the feeding roller 21 and the rotating shaft 413 are driven by gear meshing. In this embodiment, the winding device also includes a transmission assembly, which includes a first shaft 51, a second shaft 52, and a third shaft 53. One end of the feeding roller 21 is connected to the first shaft 51, which is located on the same side of the mounting frame 1 as the connecting assembly 43. The first shaft 51 is provided with a first gear 511. The mounting frame 1 is rotatably connected to the second shaft 52, which is located on the same side of the mounting frame 1 as the first shaft 51. The second shaft 52 is provided with a second gear 521 and a third gear 522 spaced apart along its axial direction. The second gear 521 meshes with the first gear 511. One end of the rotating shaft 413 is connected to the third shaft 53, which is located on the same side of the mounting frame 1 as the second shaft 52. The third shaft 53 is provided with a fourth gear 531, which meshes with the third gear 522. The gear ratio between each gear is determined according to actual needs, so that when the feeding roller 21 rotates a certain number of times and needs to cut the wrapped grass net 31, the hanging knife body 4111 just disengages from the rotating shaft 413.

[0073] Optionally, the net feeding mechanism 2 also includes several net spreading rollers 22, fixed to the mounting frame 1 and distributed along the conveying path of the straw-wrapping net 31. Along the conveying direction of the straw-wrapping net 31, the net feeding rollers 21 are located downstream of the several net spreading rollers 22, and the net spreading rollers 22 can flatten the pulled-out straw-wrapping net 31. When the free end of the net roll 3 is pulled out and wound onto the net feeding mechanism 2, for ease of operation, the straw-wrapping net 31 is usually twisted into a single strand. By setting the net spreading rollers 22, the straw-wrapping net 31 is driven to flatten, ensuring that the straw-wrapping net 31 can maintain a flat and straight state when conveyed downstream, providing a good foundation for subsequent wrapping of straw.

[0074] In one optional embodiment, the spreading roller 22 is a spiral spreading rod, and the straw net 31 located on the spiral spreading rod is pushed and spread out to both sides by the thrust of the spiral. In another optional embodiment, such as Figure 8 As shown, the spreading roller 22 includes a first roller section 221 and a second roller section 222. The second roller section 222 is provided on both sides of the first roller section 221 along its axial direction. The axis of the first roller section 221 is set at an angle to the axis of the second roller section 222. During the downstream conveying process, the grass net 31 located on the spreading roller 22 automatically unfolds to the two ends of the second roller section 222 that are set at an angle to the axis of the first roller section 221.

[0075] Optionally, the net feeding mechanism 2 also includes a net clamping roller assembly 23, which is rotatably connected to the mounting frame 1. The portion of the net roll 3 pulled out is clamped between the net clamping roller assembly 23 and the net feeding roller 21. The net clamping roller assembly 23 and the net feeding roller 21 together clamp the wrapped grass net 31. By applying appropriate pressure to the wrapped grass net 31, the friction between the wrapped grass net 31 and the net feeding roller 21 is increased, ensuring that the wrapped grass net 31 will not slip during the conveying process. This allows the net feeding roller 21 to accurately convey the wrapped grass net 31 at a predetermined speed and rhythm, ensuring the stability and continuity of the conveying process.

[0076] In one alternative embodiment, such as Figure 3 , Figure 4As shown, the clamping roller assembly 23 includes a second elastic element 231 and two clamping rollers 232. The two clamping rollers 232 are spaced apart on both sides of the feeding roller 21 along the conveying direction of the wrapped grass net 31. Both ends of the clamping rollers 232 are rotatably connected to mounting seats 233, which are rotatably connected to the mounting frame 1. The two ends of the second elastic element 231 are respectively hung on the two mounting seats 233 of the two clamping rollers 232. The second elastic element 231 is configured to drive the two clamping rollers 232 closer together to press against the feeding roller 21. By pulling the two clamping rollers 232 closer together through the second elastic element 231, both clamping rollers 232 press against the feeding roller 21. When the wrapped grass net 31 is located between the clamping rollers 232 and the feeding roller 21, the elastic tension of the second elastic element 231 will cause the clamping rollers 232 to apply a certain pressure to the wrapped grass net 31, preventing the wrapped grass net 31 from slipping during conveying.

[0077] An embodiment of the present invention also provides a baling machine, which includes a frame and the aforementioned wire wrapping device, the wire wrapping device being mounted on the frame. The baling machine with the aforementioned wire wrapping device has higher baling efficiency.

[0078] Specifically, such as Figure 2 As shown, the wire mesh roll 3 is fixed to the frame by the wire mesh roll frame 6.
