[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] An automatic netting structure for a round baler (hereinafter referred to as the netting structure) is disclosed. The netting structure is used to convey a net body 10 into the round baler. The net body 10 performs netting operations inside the round baler as the bales rotate. After the operation is completed, the net body 10 is cut to achieve automatic netting operation. For ease of description, the position of the net body 10 is described based on the width direction and the conveying direction.

[0043] In some embodiments, refer to Figure 1 The main body of the above-mentioned netting structure is composed of a support component and a netting component. The support structure serves as the mounting carrier for the other components (such as the netting component) in the netting structure. Specifically, the support component includes a first support plate 100 and a second support plate 101 spaced apart in the width direction of the net body 10. Both the first support plate 100 and the second support plate 101 extend along the height direction and the conveying direction of the net body 10.

[0044] In some embodiments, the above-mentioned web winding assembly includes a web roller component 200 and a web winding roller body 201 arranged sequentially along the conveying direction of the web body 10. Both the web roller component 200 and the web winding roller body 201 are rotatably mounted on a support assembly, meaning that both the web roller component 200 and the web winding roller body 201 are rotatably mounted on a first support plate 100 and a second support plate 101 at their respective axial ends. Specifically, the web roller component 200 is configured to rotate around its own axis, and multiple layers of web body 10 are wound on the web roller component 200. The rotation of the web roller component 200 enables the web body 10 to rotate. The winding and unwinding of the 0 are carried out simultaneously. At the same time, the first support plate 100 is provided with a brake assembly 600 at one end of the winding roller 201 to limit the rotation of the winding roller 201 during the wire cutting operation, that is, to prevent the wire roller component 200 from rotating during the wire cutting process. For example, the brake assembly 600 consists of a brake pad 601 assembled at one end of the wire roller component 200 and a clamping member 602 that applies clamping force to the brake pad 601. The action control of the brake assembly 600 is realized by whether the clamping member 602 clamps the brake pad 601.

[0045] Continue to refer to Figure 1 and combined Figure 4 The aforementioned web winding assembly further includes a pressure roller 204, which is disposed on the side of the web winding roller 201 away from the web roller member 200 and configured to apply a pressure force to the web 10 on the web winding roller 201. In some embodiments, refer to... Figure 3 Both the outer sides of the first support plate 100 and the second support plate 101 are equipped with a clamping force adjustment structure. Specifically, the clamping force adjustment structure includes a connecting plate 205 and a third tension spring 502. The top end of the connecting plate 205 is rotatably mounted on the first support plate 100 (the second support plate 101), and the two ends of the clamping roller 204 are respectively connected to the middle of the two connecting plates 205. Correspondingly, one end of the third tension spring 502 is fixed on the first support plate 100 (the second support plate 101), and the other end is connected to the bottom end of the connecting plate 205. The third tension spring 502 is in a stretched state. With the help of the restoring force of the third tension spring 502, the clamping roller 204 and the winding roller 201 can be kept in contact to achieve the clamping of the net body 10.

[0046] Reference Figure 1The aforementioned wrapping assembly further includes a first connecting rod 302 and a cutting knife holder 30. The first connecting rod 302 extends along the width direction of the net body 10, and its two ends are rotatably mounted on the first support plate 100 and the second support plate 101, respectively. The cutting knife holder 30 is mounted on the first connecting rod 302 and includes a cutting knife 303 extending along the width direction of the net body 10. The cutting knife holder 30 is configured to switch between a first position and a second position as the first connecting rod 302 rotates. In the first position, the cutting knife 303 separates from the net body 10, and the net body 10 wrapped on the wrapping roller component 200 is conveyed to the round bundler via the wrapping roller 201. In the second position, the cutting knife 303 contacts the net body 10 to cut the net body 10.

[0047] In some embodiments, the aforementioned net-cutting knife holder 30 includes a first movable plate 300 and a second movable plate 301 spaced apart in the width direction of the net body 10. Both the first movable plate 300 and the second movable plate 301 include a first plate body portion and a second plate body portion (see reference). Figure 6 (Taking the second movable plate 301 as an example for illustration), the first plate body is disposed above the winding roller body 201, and the first plate body has a mounting end fixed to the first connecting rod 302 and a movable end extending towards the winding roller component 200. At this time, the first movable plate 300 and the second movable plate 301 can rotate synchronously around the axis of the first connecting rod 302, that is, the position switching of the wire cutting knife holder 30 is realized by the rotation of the first movable plate 300 and the second movable plate 301 around the axis of the first connecting rod 302. In some embodiments, the movable ends of the first movable plate 300 and the second movable plate 301 are connected by the second connecting rod 304. Continuing to refer to... Figure 1 The second plate portion is formed by extending downward from the movable end of the first plate portion. Correspondingly, the cutting tool 303 is connected to the lower end of the second plate portion. Based on the spacing design between the first movable plate 300 and the second movable plate 301, the normal conveying of the mesh 10 can be ensured. Combined with the position design of the cutting tool 303, the cutting tool 303 can be positioned under the mesh 10 to ensure the normal conveying of the mesh 10.

[0048] Continue to refer to Figure 1 and combined Figure 4The aforementioned web-winding assembly also includes a limiting structure for controlling the movement of the cutting tool 303. Specifically, the limiting structure includes a limiting rod 206 extending along the width direction of the web body 10. Both ends of the limiting rod 206 pass through the first movable plate 300 and the second movable plate 301, respectively, and extend outwards. Correspondingly, at least the first support plate 100 is provided with an arc-shaped groove 102 for the limiting rod 206 to slide. The center of the arc-shaped groove 102 is located on the center line of the first connecting rod 302, and the arc-shaped groove 102 constitutes a limiting groove for the movable plate. Specifically, when the limiting rod 206 moves with the movable plate to one end of the arc-shaped groove 102 (e.g., ...), the limiting rod 206... Figure 4 When the lower middle section is in the middle position, the corresponding cutter holder 30 is in the second position. When the limiting plate moves with the movable plate to the other end of the arc groove 102 ( Figure 4 (Upper middle), the cut-off knife holder 30 is in the first position.

[0049] Continue to refer to Figure 1 and combined Figure 4 The aforementioned limiting structure also includes a rotating shaft 401, a mesh-breaking locking hook 400, and a first tension spring 500. Based on the synergistic effect of the rotating shaft 401, the mesh-breaking locking hook 400, and the first tension spring 500, the mesh-breaking cutter holder 30 can be switched between its first and second positions, and the mesh-breaking cutter holder 30 can be maintained in both positions. Specifically, refer to... Figure 1 The aforementioned rotating shaft 401 is rotatably mounted on the second support plate 101 and extends along the width direction of the web 10. The rotating shaft 401 is configured to rotate with the winding roller. In some embodiments, the second support plate 101 is provided with a transmission structure, through which the rotational motion of the winding roller 201 is transmitted to the rotating shaft 401, thereby driving the rotating shaft 401 to rotate. Specifically, refer to... Figure 5 The transmission structure includes a transmission shaft 402, a drive gear 403 mounted on one end of the shaft of the winding roller 201, and a driven gear 406 mounted on one end of the rotating shaft 401. The transmission shaft 402 extends along the width direction of the mesh body 10, and both ends of the transmission shaft 402 are rotatably mounted on two support shafts. At the same time, one end of the transmission shaft 402 extends to the outside of the second support plate 101 and a first transmission gear 404 and a second transmission gear 405 are arranged thereon. The first transmission gear 404 meshes with the drive gear 403 on the shaft of the winding roller 201, and the second transmission gear 405 meshes with the driven gear 406 on the rotating shaft 401.

[0050] Reference Figure 1The aforementioned net-breaking hook 400 is rotatably mounted on the movable end of the first plate body 301a in the second movable plate 301. Exemplarily, the net-breaking hook 400 is rotatably connected to the second movable plate 301 via an auxiliary rod. Specifically, one end of the auxiliary rod is fixed to the movable end of the first plate body 301a in the second movable plate 301, and the other end extends outward along the width direction of the net body 10. Correspondingly, the net-breaking hook 400 is rotatably mounted on the auxiliary shaft to achieve a rotatable connection between the net-breaking hook 400 and the movable end of the second movable plate 301. Continuing to refer to... Figure 1 The aforementioned mesh-breaking hook 400 has an arc-shaped surface 400a, which is configured such that the mesh-breaking knife holder 30 is in a first position and hooks the rotating shaft 401 to keep the mesh-breaking knife holder 30 in the first position. Simultaneously, the surface of the rotating shaft 401 has a friction texture structure. When the rotating shaft 401 rotates with the rotation of the winding roller 201, the mesh-breaking hook 400 rotates synchronously around the movable end of the second movable plate 301 due to the friction between the friction texture structure on the rotating shaft 401 and the arc-shaped surface 400a of the mesh-breaking hook 400. Figure 4 The mesh cutter 30 gradually separates from the rotating shaft 401 in a counterclockwise direction. When the mesh cutter hook 400 rotates to be completely separated from the rotating shaft 401, the force between the rotating shaft 401 and the mesh cutter hook 400 disappears, so that the mesh cutter holder 30 can move from the first position (i.e., can start to move to the second position). Specifically, one end of the limiting rod 206 passes through the arc groove 102 on the first movable plate 300 and is connected to one end of the first tension spring 500. At the same time, the first tension spring 500 is in a stretched state when the mesh cutter holder 30 is in the first position. When the force between the rotating shaft 401 and the mesh cutter hook 400 disappears, the restoring force of the first tension spring 500 can drive the mesh cutter holder 30 to move, so that the cutting tool 303 moves to the second position.

[0051] Reference Figure 1 The aforementioned net-winding structure also includes an opening and closing signal plate 104, which is configured to move under the action of an external drive structure (e.g., a linkage structure). When the net-cutting knife holder 30 is in the second position, after the cutting knife 303 cuts the net body 10, the net-winding operation ends. Under the force of the external drive structure, the opening and closing signal plate 104 drives the net-cutting knife holder 30 to reset (i.e., move from the second position to the first position). Correspondingly, the net-cutting hook 400 falls down and re-contacts the rotating shaft 401 so that the net-cutting knife holder 30 is held in the first position.

[0052] In some embodiments, the above-mentioned winding structure further includes an adjusting rod 202 and a dividing rod 203 sequentially arranged between the winding roller component 200 and the winding roller 201 along the conveying direction of the net body 10. The two ends of the dividing rod 203 are rotatably mounted on the first support plate 100 and the second support plate 101, respectively, and both ends of the dividing rod 203 are provided with threaded structures. Based on the threaded structures, the net body 10 can be prevented from gathering towards the middle during the conveying process, thus reducing its width.

[0053] Reference Figure 2 and combined Figure 3 The aforementioned adjusting rod 202 extends along the width direction of the net body 10, and both the first support plate 100 and the second support plate 101 are provided with sliding grooves 103 for the adjusting rod 202 to slide. Each sliding groove 103 has a first end 103a and a second end 103b, wherein the second end 103b is located between the first end 103a and the net roller component 200. During the net winding operation, the adjusting rod 202 is positioned at the second end 103b of the sliding groove 103. During the net cutting operation... The adjusting rod 202 can move to a first position under the action of, for example, the second tension spring 501, so as to achieve tension of the net body 10. Specifically, one end of the second tension spring 501 is fixed to the first support plate 100, and the other end is connected to the end of the adjusting rod 202 that extends outside the first support plate 100. At the same time, the second tension spring 501 is in a stretched state when the adjusting rod 202 is in the first end 103a position of the sliding groove 103. In some examples, the sliding groove 103 is an arc-shaped groove.
