Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment technology, and in particular to a wire wrapping transmission mechanism and a baler. Background Technology

[0002] In recent years, with the upgrading of agricultural industrial structure and the rapid development of animal husbandry, the demand for forage has increased year by year, and the utilization rate of crop straw has also increased year by year. This has placed higher demands on the collection, storage, and transportation of straw and forage. Currently, the commonly used straw and forage harvesting equipment are square balers and round balers.

[0003] In the unique planting environment, operating hours are affected by the seasons, and the tight schedule and heavy workload make improving operating efficiency and quality a key research topic. Looking at the development of balers in recent years, manufacturers have gradually emphasized operational quality. The quality of the wrapping operation directly affects the baling quality and has a significant impact on bale transportation. Therefore, improving the operational quality of the wrapping system has become a pressing problem for manufacturers.

[0004] Existing round baler wrapping systems mostly use a single-drive mode, i.e., an electromagnetic clutch-driven pulley. Although this single-drive system is simple in structure, the wrapping effect is unstable, the speed cannot be controlled, and problems such as netting, loose wrapping, and failure to form a shape are prone to occur.

[0024] This application also provides a baler, including the web-winding transmission mechanism described in any of the above technical solutions, and thus possesses all the beneficial technical effects of the web-winding transmission mechanism, which will not be repeated here.

[0025] Compared with the prior art, the beneficial effects of this application are as follows:

[0026] The net-winding transmission mechanism provided in this application includes: a net-casting system, which includes a first driving member and a first driven member that are driven to each other; a net tension control system, which includes a second driving member and a second driven member that are driven to each other; a roller shaft, on which the second driving member is disposed; the first driving member is connected to the roller shaft through a first connecting member; and a net-casting shaft, on which the first driven member is disposed; and the second driven member is connected to the net-casting shaft through a second connecting member.

[0042] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] The following reference Figures 1 to 6This application describes the web-winding transmission mechanism and baler according to embodiments.

[0044] See Figures 1 to 6 As shown, an embodiment of this application provides a net-winding transmission mechanism, which includes: a net-casting system, a net tension control system, a net-casting shaft 2, and a roller shaft 1. The net-casting system includes a first driving member and a first driven member, which are drive-connected and the first driven member can move synchronously with the first driving member. The net tension control system includes a second driving member and a second driven member, which are drive-connected and the second driven member can move synchronously with the second driving member. Both the first and second driving members are mounted on the roller shaft 1, and both the first and second driven members are mounted on the net-casting shaft 2.

[0045] Specifically, the first driving member and the second driving member are both sleeved on the same end of the roller shaft 1, with the first driving member located outside the second driving member. The first driven member and the second driven member are both sleeved on the same end of the net-casting shaft 2, with the first driven member located outside the second driven member.

[0046] Furthermore, the first driving component is specifically an electromagnetic clutch 3, comprising an inner ring and an outer ring. The inner ring of the electromagnetic clutch 3 is connected to the roller shaft 1 via a first connecting member 11, which is specifically a common bearing. When the roller shaft 1 rotates, the outer ring of the electromagnetic clutch 3 does not rotate with the roller shaft 1. After the electromagnetic clutch 3 receives an electrical signal, the outer ring begins to rotate, thus ensuring that the outer ring of the electromagnetic clutch 3 does not move during non-operational times. The first driven component is a net-winding pulley 4, which is connected to the electromagnetic clutch 3 via a first belt 7. When the net-winding conditions are met, an electrical signal is applied to the electromagnetic clutch 3, causing the outer ring of the electromagnetic clutch 3 to rotate counterclockwise, simultaneously driving the net-winding pulley 4 to rotate. The net-winding pulley 4 then drives the net-casting shaft 2 to rotate, and the net on the net-casting shaft 2 begins to be conveyed, thus enabling the net-casting system to perform net-casting operations. It should be noted that the electromagnetic clutch 3 typically operates for only a few seconds, in an intermittent mode, working only for a few seconds when the conditions for netting are met. After completing the netting action, it stops working and no longer outputs power to the first driven component. As the netting operation continues, the net continuously wraps around the bales of grass and is continuously pulled and then released. During this process, the net can exert force on the netting shaft 2.

[0047] Preferably, a first tensioning pulley 9 is provided between the electromagnetic clutch 3 and the wire mesh pulley 4. More preferably, the first tensioning pulley 9 is position-adjustable and can abut against and support the first belt 7, thereby keeping the first belt 7 in a taut state. The tension of the first belt 7 can be adjusted by adjusting the position of the first tensioning pulley 9.

[0048] Furthermore, the second driving component is a tension pulley 5, and the second driven component is a variable-diameter pulley 6. The tension pulley 5 and the variable-diameter pulley 6 are connected by a second belt 8, and the variable-diameter pulley 6 is connected to the roller shaft 1 via a second connecting member 12. The second connecting member 12 is specifically a one-way bearing. The tension pulley 5 can drive the variable-diameter pulley 6 to rotate synchronously. However, because the variable-diameter pulley 6 rotates in the same direction as the one-way bearing, it idles relative to the roller shaft 1. The rotation of the variable-diameter pulley 6 will not drive the roller shaft 1 to rotate. The one-way bearing includes an inner ring and an outer ring. The inner ring is connected to the screen-casting shaft 2, and the outer ring is connected to the second belt 8.

[0049] Preferably, a second tensioning pulley 10 is provided between the tension pulley 5 and the variable diameter pulley 6. More preferably, the second tensioning pulley 10 is position-adjustable and can abut against and support the second belt 8, thereby keeping the second belt 8 in a taut state. The tension of the second belt 8 can be adjusted by adjusting the position of the second tensioning pulley 10.

[0050] Preferably, the winding transmission mechanism further includes an elastic support member, which may specifically be a spring. One end of the elastic support member is connected to the tension belt pulley, and the other end of the elastic support member is connected to a designated position in a fixed state. The second tensioning pulley 10 contacts the outer wall surface of the second belt 8. Under the action of the elastic support member, the second tensioning pulley 10 continuously applies an inward resisting force to the second belt 8.

[0051] Furthermore, the variable diameter pulley 6 includes an inner pulley 601, an outer pulley 602, and a locking member 605. The inner pulley 601 is provided with a connecting shaft cylinder 603. The connecting shaft cylinder 603, the inner pulley 601, and the outer pulley 602 are coaxially arranged. A one-way bearing is arranged inside the connecting shaft cylinder 603 for connection with the roller shaft 1. The inner pulley 601 is fixed to the connecting shaft cylinder 603. The outer pulley 602 is detachably connected to the connecting shaft cylinder 603 and spaced apart from the inner pulley 601. Preferably, the outer pulley 602 is connected to the outer wall surface of the connecting shaft cylinder 603 by a suitable thread, so that the position of the outer pulley 602 on the connecting shaft cylinder 603 can be adjusted by rotating the outer pulley 602, thereby adjusting the distance between the outer pulley 602 and the inner pulley 601. As the outer wheel 602 moves away from the inner wheel 601, the distance between the belt groove 604 between the edge of the inner wheel 601 and the edge of the outer wheel 602 gradually increases, causing the second belt 8 to slide down a certain distance and be tensioned by the second tensioning wheel 10. The installation pitch circle of the second belt 8 becomes smaller. When the outer wheel 602 moves closer to the inner wheel 601, the second belt 8 moves upward along the belt groove 604, and the installation pitch circle of the second belt 8 becomes larger. It can be seen that the variable diameter pulley 6 can realize the variable diameter operation. Through the variable diameter operation, the speed of the variable diameter pulley 6 can be adjusted, thereby adjusting the differential speed range between the variable diameter pulley 6 and the net winding pulley 4, further adjusting the net tension, adapting to complex and changing working environments, and improving the quality of net winding operations.

[0052] The locking element 605 is a fastening screw. The outer wheel 602 has a locking hole along its radial direction. After the outer wheel 602 is adjusted to the appropriate position, the locking element 605 is inserted into the locking hole so that the locking element 605 and the connecting shaft cylinder 603 are tightly abutted, thereby locking the outer wheel 602 in the current position.

[0053] In the operation of the net-winding transmission mechanism provided in this application: the net tension pulley 5 is continuously driven by an external source, driving the variable diameter pulley 6 to rotate counterclockwise. Since the variable diameter pulley 6 is connected to the net-casting shaft 2 via a one-way bearing, the outer ring of the one-way bearing rotates with the variable diameter pulley 6, while the inner ring remains unchanged. This allows the variable diameter pulley 6 to idle relative to the net-casting shaft 2. The movement of the variable diameter pulley 6 does not affect the net-casting shaft 2, which remains stationary. Furthermore, since the electromagnetic clutch 3 is connected to the roller shaft 1 via a common bearing, the electromagnetic clutch 3 remains stationary, and the net-winding pulley 4 also remains stationary. It should be noted that the net tension pulley 5 is additionally equipped with a motor to drive its rotation, and the rotation speed of the net tension pulley 5 can be adjusted by the motor.

[0054] When the conditions for netting are met, the electromagnetic clutch 3 engages. The outer ring of the electromagnetic clutch 3 begins to work, driving the netting pulley 4 to rotate counterclockwise. The netting pulley 4 drives the netting shaft 2 to rotate, which then transmits the netting. After the electromagnetic clutch 3 reaches the required operating time (which may be, but is not limited to, 3 seconds), it stops operating. At this time, as the baling operation continues, the netting shaft 2 and the netting pulley 4 continue to rotate. The netting shaft 2 maintains its counterclockwise rotation and acts on the inner ring of the one-way bearing. The outer ring of the one-way bearing receives the power for counterclockwise rotation from the netting shaft 2, along with the inner ring. However, at this time, the netting belt... When wheel 4 loses the power provided by electromagnetic clutch 3, the winding pulley 4 no longer applies power to the net-casting shaft 2, creating a differential motion between the winding pulley 4 and the variable diameter pulley 6. Under the action of external drive, the net tension pulley 5 continuously drives the variable diameter pulley 6 to rotate counterclockwise. The speed of the net-casting shaft 2 and the speed of the variable diameter pulley 6 influence each other and eventually tend to be the same speed. During this speed change process, the rotation speed of the winding pulley 4 when the electromagnetic clutch 3 is activated is adjusted to avoid the net being tied too tightly due to excessive speed or too loosely due to excessive speed, thereby completing the control and adjustment of the net tension.

[0055] In summary, the net-winding transmission mechanism provided in this application, through two sets of coaxial asynchronous and coaxial different speed transmission systems, can not only ensure the basic net-throwing operation during net-winding operations, but also adjust the net tension within a certain range, reducing the probability of net misshapen winding, net accumulation, and loose winding, thereby helping to improve the quality and efficiency of bundling.

[0056] The embodiments of this application also provide a baler, including the web-winding transmission mechanism described in any of the above embodiments, and thus have all the beneficial technical effects of the web-winding transmission mechanism, which will not be repeated here.

[0057] The baler provided in this embodiment is preferably a round baler.

[0058] The baler provided in this application can adjust the tension of the wrapping net through the aforementioned wrapping transmission mechanism, thereby improving the wrapping effect during the baling process and thus improving the baling quality of the baler.

[0059] 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.
