Description

Technical Field

[0001] The utility model belongs to the technical field of harvester crop divider manufacturing, in particular to a floating crop divider used on a soybean harvester. Background Art

[0002] A straw divider is an important auxiliary component of a harvester. It is usually used in pairs and is arranged at both ends of the harvesting side of the harvester. Its main function is to guide and separate crops to prevent the mechanical crushing of plant branches and leaves during the operation of the harvester. With the continuous improvement of the integration of agricultural machinery products, the harvester's cutting rack and the power motor that drives the cutting rack are also generally integrated on the welded plate in the straw divider. Since the welded plate and the straw shovel in the traditional straw divider are fixedly connected, the vibration generated by the cutting rack during operation will be directly transmitted to the straw shovel, causing the end of the straw divider to shake synchronously, which greatly affects the stability of the straw divider. In addition, the separation area of the traditional straw divider is usually concentrated at the root of the crop, while the upper branches and leaves of the crop are still easy to enter the harvesting work area and entangled on the harvesting roller, which seriously affects the working efficiency of the harvesting roller. Therefore, in order to improve the working stability of the straw divider and the anti-entanglement ability of the straw divider, it is very practical to develop a floating straw divider for soybean harvesters.

[0034] The floating straw divider provided in the present application uses a floating component 5 as a connecting component between the square beam 2 and the welded plate 3, optimizing the traditional fixed connection method into a movable connection method, which can effectively prevent the vibration generated by the operation of the harvester from being transmitted to the straw divider 1, and effectively ensure the working stability of the end of the straw divider.

[0035] Specific implementation method 2: Combination Figures 1 to 9This embodiment differs from the first embodiment in that a floating connection block 21 is provided at the bottom of the square beam 2, integrally formed with the beam 2. The top end of the floating assembly 5 is inserted into the floating connection block 21 and is detachably connected thereto. A mounting hole 22 is machined into the square beam 2, located near the end where the beam 2 connects to the harvester body 9. The height adjustment assembly 4 is inserted into the mounting hole 22. The remaining components and connection methods are the same as those of the first embodiment.

[0036] In this embodiment, the floating connection block 21 is an L-shaped block, the horizontal portion of which is used for detachable connection with the floating assembly 5 , and the vertical portion is used for rigid connection with the square beam 2 .

[0037] Specific implementation method three: Combination Figures 1 to 9 This embodiment differs from the second embodiment in that a guide cylinder 31 is fixedly attached to the middle portion of the outer side of the welded plate 3, and the guide cylinder 31 is arranged perpendicular to the outer side of the welded plate 3. A tooth cutting connecting groove 32 is machined into the lower portion of the outer side of the welded plate 3, and a tooth cutting drive motor mounting groove 33 is also machined into the outer side of the welded plate 3, located above the tooth cutting connecting groove 32. A tensioning connecting block 34 is also fixedly attached to the outer side of the welded plate 3.

[0038] This arrangement is mainly for improving the integration of the welded plate 3, wherein the tooth cutting drive motor mounting groove 33 and the tooth cutting connecting groove 32 are mounting areas for mounting the cutting teeth and the cutting gear motor. The guide cylinder 31 is used to cooperate with the floating component 5 to play a guiding role, which can effectively prevent the floating component 5 from detaching from the welded plate 3 during the sliding process. The tensile connection block 34 is used to connect with the welded plate tensile component 7 to ensure the stability of the arrangement of the welded plate 3.

[0039] Specific implementation method four: Combination Figures 1 to 9This embodiment is described. This embodiment differs from the third embodiment in that the height adjustment assembly 4 includes a height adjustment threaded rod 41, an upper locking nut 42, a lower locking nut 43, and a contact nut 44. The height adjustment threaded rod 41 is inserted into the mounting through-hole 22. The upper locking nut 42 and the lower locking nut 43 are both mounted on the height adjustment threaded rod 41. The upper locking nut 42 is located above the square beam 2, while the lower locking nut 43 is located below the square beam 2. The height adjustment threaded rod 41 is detachably connected to the square beam 2 via the upper locking nut 42 and the lower locking nut 43. The contact nut 44 is mounted on the end of the height adjustment threaded rod 41 and is threadedly connected to the height adjustment threaded rod 41. The height adjustment threaded rod 41 contacts the upper portion of the harvester body 9 via the contact nut 44. Other components and connection methods are the same as those of the third embodiment.

[0040] Specific implementation method five: Combination Figures 1 to 9 This embodiment differs from the fourth embodiment in that a rubber layer is attached to the contact nut 44 on the side in contact with the harvester body 9. The other components and connection methods are the same as those of the fourth embodiment.

[0041] In combination with the description of specific method four and specific implementation method five, by changing the length of the square beam 2 extended downward by the height-adjusting threaded rod 41, the initial height of the straw-dividing shovel 1 and the square beam 2 as a whole can be adjusted, so that the straw-dividing shovel 1 can adjust the working height according to the needs of the working environment. The bottom of the contact nut 44 is attached with a rubber layer, which can effectively protect the harvester body and avoid damage to the harvester body due to rigid contact.

[0042] Specific implementation method six: combination Figures 1 to 9 This embodiment is described. The difference between this embodiment and the specific embodiment 5 is that the floating assembly 5 includes a cylinder floating joint 51, a connecting rod 52, a fixing nut 53, a guide stud 54 and an L-shaped guide plate 55. The cylinder floating joint 51 is arranged at the top of the connecting rod 52, and the cylinder floating joint 51 and the connecting rod 52 are detachably connected. The connecting rod 52 is sleeved on the guide stud 54, and the connecting rod 52 is threadedly connected to the guide stud 54. The fixing nut 53 is arranged below the connecting rod 52, and the fixing nut 53 is sleeved on the guide stud 54. The connecting rod 52 is mounted on the guide stud 54 and locked in place with the guide stud 54 via a fixing nut 53. An L-shaped guide plate 55 is mounted at the bottom end of the guide stud 54 and fixedly connected to the horizontal portion of the L-shaped guide plate 55. A strip guide groove 56 is machined along the vertical portion of the L-shaped guide plate 55 along its length. The L-shaped guide plate 55 is sleeved onto the guide cylinder 31 via the strip guide groove 56 and is slidably connected to the guide cylinder 31 via the strip guide groove 56. The remaining components and connection methods are the same as those of the fifth embodiment.

[0043] In this embodiment, the floating assembly 5 is the main core component of the present application, which is connected to the square beam 2 through the cylinder floating joint 51. Relying on the high degree of freedom of the cylinder floating joint 51 itself, the floating assembly 5 and the square beam 2 have high adaptability. The L-shaped guide plate 55 is used to connect with the guide cylinder 31 on the welded plate 3. The guide groove 56 in the L-shaped guide plate 55 provides a guide track for the guide cylinder 31, so that the movement generated by the welded plate 3 after synchronous vibration with the cutting tooth drive assembly forms a reciprocating displacement in the guide groove 56, so that the movement of the welded plate 3 and the movement of the grain-dividing tooth 1 can be effectively separated, thereby ensuring the working stability of the grain-dividing tooth 1.

[0044] Specific implementation method seven: combination Figures 1 to 9 This embodiment is described. This embodiment differs from the sixth embodiment in that the welded plate tension assembly 7 includes a No. 1 threaded connecting rod, a No. 2 threaded connecting rod, and a buffer spring. The buffer spring is disposed between the No. 1 and No. 2 threaded connecting rods, and the No. 1, No. 2 threaded connecting rods, and the buffer spring are coaxially arranged. One end of the No. 1 threaded connecting rod is fixedly connected to one end of the buffer spring, and one end of the No. 2 threaded connecting rod is fixedly connected to the other end of the buffer spring. The other end of the No. 1 threaded connecting rod is inserted into the upper and lower extension frames of the harvester body 9 and is detachably connected to the lower extension frame via bolts. The other end of the No. 2 threaded connecting rod is inserted into the tension connection block 34 and is detachably connected to the tension connection block 34 via bolts. Other components and connection methods are the same as those of the sixth embodiment.

[0045] In this embodiment, since the welded plate 3 and the square beam 2 adopt a floating connection method, in order to increase the connection reliability between the welded plate 3 and the harvester body, a welded plate tensioning assembly 7 is set between the welded plate 3 and the harvester body, and a spring is used in the middle as an adaptive component. When encountering a small earth slope or stone during work, the welded plate 3 will rise with the road conditions. After the welded plate 3 passes the small earth slope or stone, the spring in the welded plate tensioning assembly 7 will cause the welded plate 3 to return to its initial position.

[0046] Specific implementation method eight: combination Figures 1 to 9 This embodiment is described. The difference between this embodiment and the seventh embodiment is that the floating crop divider further includes an anti-winding component 6, which is installed on the top of the crop divider 1. The other components and connection methods are the same as those of the seventh embodiment.

[0047] Specific implementation method nine: Combination Figures 1 to 9This embodiment is described. The difference between this embodiment and the eighth embodiment is that the anti-winding assembly 6 includes an anti-winding roller 61, an anti-winding frame 62 and a rotating shaft 63. The anti-winding frame 62 is arranged on the top of the grain-dividing shovel 1, and the bottom end of the anti-winding frame 62 is detachably connected to the grain-dividing shovel 1. The rotating shaft 63 is arranged between the anti-winding frame 62 and the grain-dividing shovel 1. The top end of the rotating shaft 63 is inserted into the inner top of the anti-winding frame 62 and is rotatably connected to the anti-winding frame 62. The bottom end of the rotating shaft 63 is inserted into the top of the grain-dividing shovel 1 and is rotatably connected to the grain-dividing shovel 1. The anti-winding roller 61 is sleeved on the outer circumferential surface of the rotating shaft 63 and rotates synchronously with the rotating shaft 63. The other components and connection methods are the same as those of the eighth embodiment.

[0048] In combination with the description of specific embodiments eight to nine, the anti-winding roller 61 can effectively prevent the branches and leaves of crops on both sides of the working area from directly contacting the harvesting roller, and the anti-winding roller 61 has rotational freedom. When the branches and leaves contact the outer wall of the anti-winding roller 61 in the process of moving forward with the cutter, the branches and leaves will be turned away from the area where the harvesting roller is located under the action of inertia, thereby avoiding the crop branches and leaves from being entangled in the harvesting roller to the greatest extent and ensuring the working efficiency of the harvesting roller.

[0049] Specific implementation method ten: Combination Figures 1 to 9 This embodiment is described. The difference between this embodiment and the ninth embodiment is that the floating crop divider further includes a protective cover 8, which is buckled onto the square beam 2. The other components and connection methods are the same as those of the ninth embodiment.

[0050] In this arrangement, since the square beam 2 is long but the end face size is relatively small, its supporting strength is limited and it is easy to deform when hit. Therefore, the square beam 2 can be protected by the protective cover 8 to improve the use strength and service life of the square beam 2.

[0051] The present invention has been disclosed as above with preferred implementation cases, but it is not intended to limit the present invention. Any technician familiar with the profession can make slight changes or modifications to the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. Equivalent implementation cases with equivalent changes can be made by using the above-disclosed structures and technical contents. However, any simple modifications, equivalent changes and modifications made to the above implementation cases based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.

[0052] How it works

[0053] The floating straw divider provided by the present application is used for a soybean harvester. When the straw divider is in operation, the straw divider is first installed on the harvester body 9 as the connection relationship described in Specific Embodiments 1 to Specific Embodiments 10 is described. As the harvesting work proceeds, the cutting tooth drive motor drives the cutting teeth to cut the bottom of the crop. Working vibrations are generated during the cutting process. These vibrations are transmitted to the welded plate 3 in the straw divider. The welded plate 3 moves synchronously with the cutting tooth drive motor. As the welded plate 3 moves, the guide cylinder 31 reciprocates in the strip guide groove 56 in the L-shaped guide plate 55 and does not contact the square beam 2 located above the welded plate 3. Therefore, the vibration will not be transmitted to the square beam 2 and the straw dividing shovel 1 connected to the square beam 2, thereby ensuring the stability of the straw dividing shovel 1 during operation.

[0054] When it is necessary to raise the working position of the dividing shovel 1, it can be achieved through the cooperation of the height adjustment component 4 and the floating component 5. By loosening the upper locking nut 42 and the lower locking nut 43, the height adjustment threaded rod 41 can slide freely relative to the square beam 2. By adjusting the length of the height adjustment threaded rod 41 extending below the square beam 2, the working height of the square beam 2 relative to the harvester body 9 is adjusted. When the working height of the square beam 2 is raised, the height adjusted by the height adjustment component 4 is compensated by adjusting the relative displacement of the connecting sleeve 52 in the floating component 5 relative to the guide stud 54, so as to achieve a stable connection between the square beam 2 and the floating component 5.
