[0002] The existing rice harvesting machine cutting table cutting knife transmission device adopts an exposed swing ring transmission mechanism, and the specific structure is: a driving wheel is provided at one end of the driving shaft, and the axis of the driving wheel forms an angle with the axis of the driving shaft; the swing ring cooperates with the outer peripheral side of the driving wheel to convert the rotational motion of the driving wheel into reciprocating torsion of the swing ring, and the swing shaft is connected to the swing ring, and the reciprocating torsion of the swing ring is converted into the reciprocating swing of the swing shaft, thereby realizing the cutting process of driving the cutting knife to reciprocate.

[0003] The swing ring transmission mechanism is prone to poor lubrication because the swing ring and driving wheel and other transmission mechanisms are exposed. At the same time, the driving shaft, swing ring, swing shaft, etc. are all long axis structures, and it is also necessary to ensure that the axis of the swing ring, the axis of the driving wheel and the axis of the driving shaft intersect at the same point, which makes processing difficult. The above problems also cause a high failure rate of the swing ring transmission mechanism, and the overall failure rate reaches about 15%. Utility Model Content

DETAILED DESCRIPTION

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] This utility model refers to Figure 1-3 .

[0035] The utility model provides a rice harvester cutting table swing ring box, comprising a shell 1, wherein an input shaft 2, a hollow shaft 3, a swing ring seat 4, and a swing ring frame 5 are arranged in the shell 1, the input shaft 2 is horizontally arranged and one end extends out of the shell 1, the hollow shaft 3 is sleeved on the input shaft 2, and the axis of the outer ring side of the hollow shaft 3 forms an angle with the axis of the input shaft 2; the swing ring seat 4 is movably sleeved on the hollow shaft 3, and the middle part of the swing ring seat 4 and the position at the same height as the axis of the input shaft 2 are connected to the swing ring frame 5; the upper end of the swing ring frame 5 extends out of the shell 1 and is connected with a swing arm 6.

[0036] principle:

[0037] One end of the input shaft 2 extending out of the housing 1 can be used to connect to a driving device to input rotational power. The hollow shaft 3 is sleeved on the input shaft 2 and rotates with the input shaft 2. The axis of the outer ring side of the hollow shaft 3 forms an angle with the axis of the input shaft 2, so the two ends of the hollow shaft 3 produce rotation and circular swing (circular motion). The swing ring seat 4 is movably sleeved on the hollow shaft 3. Due to the constraint of the swing ring frame 5, the swing ring seat 4 does not rotate, but the two ends adaptively produce circular swing (circular motion) with the two ends of the hollow shaft 3. On the middle section of the swing ring seat 4 (i.e., the section where the axis of the swing ring seat 4 and the axis of the input shaft 2 are located), the horizontal sides of the section (i.e., the middle of the swing ring seat 4 and the position at the same height as the axis of the input shaft 2) only produce horizontal swing. The swing ring frame 5 is connected to this position (i.e., the middle of the swing ring seat 4 and the position at the same height as the axis of the input shaft 2), so the swing ring frame 5 produces horizontal reciprocating rotation (i.e., attached Figure 1 The upper end of the swing ring frame 5 transmits the motion to the swing arm 6, so the swing arm 6 swings horizontally.

[0038] In summary, by adopting the utility model, the hollow shaft 3 is sleeved on the input shaft 2, the swing ring seat 4 is movably sleeved on the hollow shaft 3, the axis center of the swing ring seat 4 coincides with the axis center of the outer ring side of the hollow shaft 3, thereby ensuring that the three axes intersect at one point, and eliminating the long axis structure, which greatly reduces the difficulty of processing; at the same time, the transmission mechanism is assembled in the housing 1, which is easy to lubricate, ensuring the smoothness of the rotation of the hollow shaft 3 relative to the swing ring seat 4 and the adaptive swing of the swing ring seat 4, thereby greatly reducing the failure rate.

[0039] Further, such as Figure 1 As shown, a connecting shaft 7 extends horizontally from the middle of the swing ring seat 4 and at the same height as the axis of the input shaft 2 , and the connecting shaft 7 is connected to the swing ring frame 5 via a first bearing 8 .

[0040] The swing components of the two ends of the swing ring seat 4 along the up and down directions correspond to the rotation of the connecting shaft 7. Through the freedom of rotation of the connecting shaft 7 relative to the swing ring frame 5, it is convenient to compensate for the swing of the swing ring seat 4, retain the horizontal swing and transmit it to the swing ring frame 5, with good reliability, and the first bearing 8 reduces the resistance.

[0041] Furthermore, an elastic retaining ring 9 for the shaft hole is provided at a position corresponding to the first bearing 8 in the swing ring frame 5 , and the elastic retaining ring 9 for the shaft hole is located on a side of the first bearing 8 away from the swing ring seat 4 .

[0042] It is convenient to restrict the axial movement of the first bearing 8, and has good reliability and long service life.

[0043] Further, such as Figure 1-2As shown: the lower end and the upper part of the swing ring frame 5 are both cylindrical, the lower end of the swing ring frame 5 is connected to the housing 1 through a second bearing 10, and the upper part of the swing ring frame 5 is connected to the housing 1 through a third bearing 11.

[0044] The reciprocating rotation path of the swing ring frame 5 is stable, reliable, has low resistance and smooth movement.

[0045] Furthermore, a fourth bearing 12 is provided between the upper part of the swing ring frame 5 and the housing 1, and a limit ring 13 is provided between the fourth bearing 12 and the third bearing 11; the first bearing 8, the second bearing 10 and the third bearing 11 are all deep groove ball bearings, and the fourth bearing 12 is a cylindrical roller bearing.

[0046] The movement stability of the upper part of the swing ring frame 5 is improved; at the same time, the deep groove ball bearing bears part of the axial force, so that the movement of the swing ring frame 5 is stable and the vibration is reduced.

[0047] Furthermore, an oil seal 14 is provided at the upper end of the housing 1 , and the oil seal 14 is sleeved on the upper part of the swing ring frame 5 .

[0048] It is convenient to seal and prevent the lubricating oil in the housing 1 from leaking.

[0049] Furthermore, the swing ring seat 4 and the hollow shaft 3 are connected via a fifth bearing 15 .

[0050] The movement resistance of the hollow shaft 3 relative to the swing ring seat 4 is reduced, and the smoothness is good and the movement is reliable.

[0052] Preferably, the blocking structure 16 on one side adopts an elastic retaining ring, and the blocking structure 16 on the other side adopts a nut and a stop washer, and the stop washer is located between the nut and the fifth bearing 15. This is convenient for improving adaptability and avoiding structural interference caused by insufficient processing accuracy.

[0053] The two tapered roller bearings and the blocking structure 16 facilitate the bearing of the axial force of the swing ring seat 4, thereby preventing the swing ring seat 4 from axially moving and causing structural interference, and achieving good reliability.
