[0056] The following reference Figures 1 to 7The present application describes the braking device for a round baler and the baler as described in the embodiments.

[0057] See Figures 1 to 7 As shown, where, Figure 5 Arrow A in the diagram indicates the rotation direction of the swing arm weld 9 during braking, arrow B indicates the contraction direction of the elastic connector 2 during braking, and arrow C indicates the rotation direction of the drive shaft 11 during braking. An embodiment of this application provides a braking device for a round baler. This braking device includes: a fixed assembly, a brake 1, a blade holder weld 7, a working rubber roller 5, a brake disc 8, and a connecting mechanism. The blade holder weld 7 and the working rubber roller 5 are rotatably connected to the fixed assembly. The brake 1 is disposed on the fixed assembly. The brake disc 8 is connected to the working rubber roller 5. The brake 1 is connected to the blade holder weld 7 via the connecting mechanism. The brake 1 can change its state as the blade holder weld 7 moves, thereby enabling the brake 1 to act on the brake disc 8, causing the working rubber roller 5 to brake and stop operating.

[0058] Specifically, the fixing component includes a first fixing plate 4 and a second fixing plate 6, which are arranged facing each other and are respectively fixed to the designated position of the round strapping machine. The first fixing plate 4 has a first mounting hole and the second fixing plate 6 has a second mounting hole, which are directly opposite each other.

[0059] The first fixing plate 4 is also provided with a first slide rail 401, which is an arc-shaped slide rail. The first slide rail 401 is located on the side of the first mounting hole, and the arc of the first slide rail 401 extends along the circumference of the first mounting hole. The second fixing plate 6 is provided with a second slide rail, which is also an arc-shaped slide rail. The length of the second slide rail is the same as the length of the first slide rail 401, and the two are arranged opposite each other.

[0060] Furthermore, the working rubber roller 5 is used to convey the winding net. One end of the working rubber roller 5 passes through the first mounting hole and is rotatably connected to the first mounting hole, and the other end of the working rubber roller 5 passes through the second mounting hole and is rotatably connected to the second mounting hole.

[0061] Furthermore, the blade holder welded assembly 7 is located below the working rubber roller 5. The blade holder welded assembly 7 is equipped with a cutter. When the blade holder welded assembly 7 moves downward, the cutter descends synchronously to cut the wrapped mesh. The blade holder welded assembly 7 is elongated in shape. One end of the blade holder welded assembly 7 is the first connecting end, and the other end is the second connecting end. The first connecting end is rotatably connected to the first slide rail 401 through a bearing, and the second connecting end is rotatably connected to the second slide rail through another bearing. This allows the blade holder welded assembly 7 to move obliquely downward or obliquely upward along the path defined by the first slide rail 401 and the second slide rail, and the blade holder welded assembly 7 and the cutter will not undergo significant changes in posture during the movement.

[0062] It should be noted that in this embodiment, the number of brake 1 and brake disc 8 can be one or two. When the number of both is one, both brake 1 and brake disc 8 are set on the first fixing plate 4. When the number of both is two, one brake 1 and brake disc 8 are set on the first fixing plate 4, and the other brake 1 and brake disc 8 are set on the second fixing plate 6. In this embodiment, only the first fixing plate 4 is provided with brake 1 and brake disc 8.

[0063] Furthermore, the brake disc 8 is sheet-shaped, with the side of the first fixing plate 4 facing the second fixing plate 6 defined as the inner plate surface, and the side of the first fixing plate 4 facing away from the second fixing plate 6 defined as the outer plate surface. One end of the working rubber roller 5 passes through the first mounting hole and extends to one side of the outer plate surface of the first fixing plate 4. The brake disc 8 is disposed at the end of the working rubber roller 5 located outside the first fixing plate 4, and the brake disc 8 is coaxially arranged with the working rubber roller 5. Preferably, the brake disc 8 is fastened to the working rubber roller 5 by a flat key and screws.

[0064] Furthermore, the brake 1 includes a mounting bracket 13 and brake pads, and also includes a mounting base 3, a fastening plate 14, and fasteners. The mounting base 3 is fixed to the outer surface of the first mounting plate 4 by bolts, and the fastening plate 14 is disposed on the mounting base 3. The mounting bracket 13 is fixed to the fastening plate 14 by fasteners, and the brake pads are disposed on the mounting bracket 13.

[0065] The fixing frame 13 specifically includes a fixing part 1301, a first fixing wall 1302, and a second fixing wall 1303. Preferably, the fixing part 1301, the first fixing wall 1302, and the second fixing wall 1303 have an integral structure. The first fixing wall 1302 and the second fixing wall 1303 are both plate-shaped, parallel and spaced apart from each other, and are directly opposite each other. The first fixing wall 1302 and the second fixing wall 1303 are both located on the lower surface of the fixing part 1301, and the three together form a U-shaped structure with the opening facing downward.

[0066] Preferably, there are two brake pads: a first brake pad 12 and a second brake pad 16. The top end of the first brake pad 12 is slidably connected to the inner wall of the fixing part 1301, allowing the first brake pad 12 to move closer to the second brake pad 16 or closer to and fit against the inner wall of the first fixing wall 1302. The second brake pad 16 is positioned close to the inner wall of the second fixing wall 1303, facing the first brake pad 12. A portion of the brake disc 8 is located between the first brake pad 12 and the second brake pad 16. When the first brake pad 12 moves towards the second brake pad 16, it can clamp the brake disc 8 between the first brake pad 12 and the second brake pad 16, thereby enabling the brake disc 8 and the working rubber roller 5 to brake.

[0067] Further, the connecting mechanism includes: a swing arm weld 9, a shift fork 903, and an elastic connector 2. The swing arm weld 9 includes a first connector 901 and a second connector 902. The first connector 901 has an L-shaped structure. When the first connector 901 is in its installed state, it has an upper end and a lower end. The lower end of the first connector 901 has an abutment portion for abutting against the end of the tool holder weld 7 located outside the first fixed plate 4. The shift fork 903 is disposed at the top of the first connector 901. Preferably, the shift fork 903 and the first connector 901 have an integral structure. The second connector 902 is plate-shaped and fixedly disposed on the first connector 901. The first connector 901 has a first through hole, and the second connector 902 has a second through hole, with the first through hole and the second through hole facing each other.

[0068] The elastic connector 2 is specifically a tension spring. The brake device of this round baler also includes a spring connector 15, which is disposed on the fixed base 3. One end of the elastic connector 2 is connected to the spring connector 15, and the other end of the elastic connector 2 is connected to the swing arm weld 9. Preferably, the swing arm weld 9 is provided with a connection hole, and one end of the elastic connector 2 is connected to the connection hole.

[0069] Furthermore, the connecting mechanism also includes a drive shaft 11 and a rocker arm 10. Specifically, the drive shaft 11 includes a main body 1101, which is columnar. A first connecting portion 1102 is provided at one end of the main body 1101 near the first fixed wall 1302. The outer diameter of the first connecting portion 1102 is larger than the outer diameter of the main body 1101. The first connecting portion 1102 passes through the first fixed wall 1302. The first fixed wall 1302 has a hole whose shape matches the shape of the first connecting portion 1102. The inner wall surface of the hole is provided with a second connecting portion that can be adapted to connect with the first connecting portion 1102. Preferably, the end of the first connecting portion 1102 away from the main body 1101 is connected to the first brake pad 12.

[0070] A connecting post 1103 is provided at one end of the main body 1101 away from the first fixed wall 1302. The diameter of the connecting post 1103 is smaller than the diameter of the main body 1101. Preferably, the connecting post 1103, the main body 1101 and the first connecting part 1102 are coaxially arranged. Preferably, the three have an integral structure.

[0071] The first connecting part 1102 is provided with a spiral groove 1104. The second connecting part is specifically a spiral protrusion on the inner wall of the hole of the first fixed wall 1302. The spiral protrusion and the spiral groove 1104 are adapted to each other, so that the spiral protrusion can be embedded in the spiral groove 1104. When the connecting column 1103 is pushed or pulled, the drive shaft 11 is subjected to force and can move axially, so that the first connecting part 1102 can rotate and move into or out of the first fixed wall 1302. When the first connecting part 1102 and the drive shaft 11 move toward the inside of the first fixed wall 1302 as a whole, the first brake pad 12 can be pushed toward the brake disc 8 and the second brake pad 16.

[0072] The rocker arm 10 is in the shape of a long rod or a long plate. One end of the rocker arm 10 is connected to the connecting column 1103 by bolts, and the other end of the rocker arm 10 extends into the shift fork 903. Preferably, the rocker arm 10 is partially bent to change the extension direction of the rocker arm 10, so that the rocker arm 10 can extend and be confined within the shift fork 903. When the shift fork 903 rotates with the rocker arm welding 9, the shift fork 903 can make the rocker arm 10 and the drive shaft 11 rotate together.

[0073] When the tool holder welding 7 is in the retracted state, the abutting part abuts against the end of the tool holder welding 7. When the tool holder welding 7 slides down along the slide, the abutting part separates from the tool holder welding 7. At this time, the elastic connecting member 2 is stretched or has a tendency to stretch, so the elastic connecting member 2 pulls the swing arm welding 9 to rotate counterclockwise, and then the swing arm welding 9 pushes the rocker arm 10 and the drive shaft 11 to rotate clockwise.

[0074] When the braking device of this round baler is working, as the netting operation progresses, when the required number of wrapping turns is reached, the blade holder weld 7 falls under the driving action to cut the netting. The swing arm weld 9, which was originally held against by the blade holder weld 7, swings to the right under the pulling force generated by the contraction of the elastic connector 2. The blade holder weld 7 pushes the rocker arm 10, causing the rocker arm 10 to swing to the right as well. During the movement of the swing arm, the drive shaft 11 rotates to the right. With the cooperation of the spiral groove 1104 and the spiral protrusion, the end of the drive shaft 11 near the first brake pad 12 pushes the first brake pad 12 so that the first brake pad 12 moves closer to the brake disc 8. The brake disc 8 can be clamped between the first brake pad 12 and the second brake pad 16, thereby completing the braking action.

[0075] After braking is completed, the first wrapping of the bale is marked as finished. Then the baler opens its compartment to release the bale. During the release of the bale, the blade holder weld 7 rises and returns to the state of contact with the swing arm weld 9. The blade holder weld 7 will push up the swing arm weld 9. The swing arm weld 9, rocker arm 10 and drive shaft 11 move in opposite directions. The drive shaft 11 pulls the first brake pad 12 back to the state of separation from the brake disc 8, thereby releasing the brake.

[0076] In summary, the round baler braking device provided in this application adopts a mechanical braking structure, which has strong stability and can maintain excellent braking performance for a long time. Moreover, it is not easily affected by the working environment and can have a good braking effect even in complex and harsh working environments. Compared with hydraulic and other types of braking structures, this round baler braking device not only helps to control production costs, but also reduces maintenance costs and maintenance difficulty.

[0077] The embodiments of this application also provide a baler, including the round baler braking device described in any of the above embodiments, and thus have all the beneficial technical effects of the round baler braking device, which will not be repeated here.

[0078] By configuring the aforementioned round baler braking device, this baler can effectively reduce the probability of brake module failure during the baling process, reduce the frequency of stopping and maintenance, and ensure the harvesting efficiency of this baler.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
