Description

Technical Field

[0001] This application relates to the technical field of rapid separation and assembly structures, and in particular to a rapid separation and assembly structure for a corn harvester power output assembly. Background Technology

[0002] The power take-off (PTO) assembly of a corn harvester is the device that transmits the engine's power to various working parts. The PTO shaft is the core component of the PTO assembly, typically connected to the engine's crankshaft, and transmits the engine's rotational power to other parts via splines or couplings. It needs to possess sufficient strength and rigidity to withstand large torques and bending moments. Common power take-off devices for corn harvesters include: belt-driven PTO assemblies, chain-driven PTO assemblies, and driveshaft-driven PTO assemblies.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the power transmission of the corn harvester consists of multiple parts. After the load-bearing structure of the installed parts is completed, it is very inconvenient to disassemble them, which seriously affects the maintenance and repair of the corn harvester. At the same time, disassembly increases the labor intensity of workers, is time-consuming and labor-intensive, and has very low efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a quick separation and assembly structure for the power output assembly of a corn harvester.

[0005] This application provides a quick separation and assembly structure for a power output assembly of a corn harvester, employing the following technical solution: a rotating sleeve, a support sleeve rotatably inserted into the top of the inner wall of the rotating sleeve, a conical sleeve fixedly installed at the top of the support sleeve, a buffer ring fixedly installed at the top of the conical sleeve, a secondary snap-fit ​​sleeve sleeved at the top of the buffer ring, a snap-fit ​​block snapped into place at the bottom of the inner wall of the secondary snap-fit ​​sleeve, a herringbone plate fixedly installed at the middle of the side of the snap-fit ​​block away from the inner wall of the secondary snap-fit ​​sleeve, a pressure plate slidably installed at the end of the herringbone plate away from the snap-fit ​​block, the middle of the pressure plate sleeved onto the outer side of the top of the vertical rod, a threaded sleeve rotatably installed at the bottom of the vertical rod via a bearing, a lead screw threaded into the bottom of the inner wall of the threaded sleeve, and the bottom of the lead screw fixedly installed at the middle of the inner wall of the rotating sleeve.

[0006] A sliding sleeve is fixedly sleeved on the outside of the threaded sleeve. A strip-shaped block is provided on the outside of the sliding sleeve, and an external limiting sleeve is slidably sleeved on it. The outside of the external limiting sleeve is fixedly set in the middle of the inner wall of the tapered sleeve.

[0007] Optionally, a main snap-fit ​​plate is fixedly fitted onto the outer circumferential surface of the top of the support sleeve, and bolt holes are provided on the main snap-fit ​​plate near the edge.

[0008] Optionally, the top diameter of the secondary snap-fit ​​sleeve is larger than its bottom diameter, and the width of the bottom of the inner wall of the secondary snap-fit ​​sleeve is larger than the thickness of the snap-fit ​​block.

[0009] Optionally, a limiting ring is inserted into the middle position of the bottom of the herringbone plate via a collar. Fixing blocks are evenly arranged in the middle of the outer surface of the limiting ring, and the end of the fixing block away from the limiting ring is fixedly set on one side of the inner wall of the buffer ring.

[0010] Optionally, there are two pressure plates, which are symmetrically arranged on both sides of one end of the herringbone plate, and both pressure plates are sleeved on the outside of the vertical rod.

[0011] Optionally, a ratchet is fixedly sleeved on the outer circumferential surface of the bottom of the lead screw. The ratchet engages with a locking plate through its outer teeth. The middle part of the locking plate is rotatably mounted on the inner wall of the sliding groove of the inner wall of the rotating sleeve via a rotating rod. A pressure rod is fixedly mounted on the top of the locking plate at the end away from the ratchet. The pressure rod extends to the outer side of the support sleeve. A limit plate is slidably mounted on the outer side of the locking plate at the end near the ratchet. The end of the limit plate away from the locking plate is fixedly mounted on the inner wall of the rotating sleeve.

[0012] Optionally, the length of the threaded sleeve is greater than the height of the movement trajectory of the vertical rod and the pressure plate, and the length of the strip block on the outside of the sliding sleeve is greater than the height of the outer limiting sleeve.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by setting up components such as a snap-fit ​​block, a pressure plate, and a threaded sleeve, allows the threaded sleeve to move up and down when the lead screw rotates, causing the snap-fit ​​block to snap against the inner wall of the auxiliary snap-fit ​​sleeve. This enables the power component to be quickly contacted and fixed during the installation of the overall structure, reducing the use of traditional bolts during installation and facilitating subsequent quick separation and assembly. It allows operators to switch power output in a short time, reducing equipment downtime and improving overall work efficiency.

[0015] 2. This utility model incorporates components such as a sliding sleeve that slides inside an external limiting sleeve. A strip-shaped fastener positions the threaded sleeve, which rotates with the lead screw shaft. This allows the upper herringbone plate to swing rapidly under the action of the lead screw. Three sets of herringbone plates ensure the stability of the installed components. When a working part of the corn harvester malfunctions, the power output assembly can be quickly separated, isolating the faulty part from the power source, facilitating inspection and repair by maintenance personnel. After repair, the machine can be quickly reassembled and operations resumed, avoiding delays in harvesting due to prolonged downtime for maintenance. Operators do not require specialized skills or numerous tools to easily complete the operation, significantly reducing labor intensity. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses a quick separation and assembly structure for the power output assembly of a corn harvester. For example... Figure 1 and Figure 3 As shown, a rotating sleeve 1 is included. A support sleeve 19 is rotatably inserted into the top of the inner wall of the rotating sleeve 1. A main clamping plate 2 is fixedly sleeved on the outer circumferential surface of the top of the support sleeve 19. Bolt holes are provided near the edge of the main clamping plate 2. The main clamping plate 2 assists in the installation of the corn machine output assembly and increases the stability after installation.

[0023] Please see Figure 2 A tapered sleeve 3 is fixedly installed on the top of the support sleeve 19, and a buffer ring 20 is fixedly installed on the top of the tapered sleeve 3. A secondary snap-fit ​​sleeve 4 is sleeved on the top of the buffer ring 20. The top diameter of the secondary snap-fit ​​sleeve 4 is larger than its bottom diameter, and the width of the bottom of the inner wall of the secondary snap-fit ​​sleeve 4 is larger than the thickness of the snap-fit ​​block 6. The wider secondary snap-fit ​​sleeve 4 facilitates the rotation of the snap-fit ​​block 6 on its inner wall, so that the snap-fit ​​block 6 can tightly connect the secondary snap-fit ​​sleeve 4 with the buffer ring 20 below.

[0024] Please see Figure 3A snap-fit ​​block 6 is snap-fitted at the bottom of the inner wall of the secondary snap-fit ​​sleeve 4. A herringbone plate 7 is fixedly installed at the middle of the side of the snap-fit ​​block 6 away from the inner wall of the secondary snap-fit ​​sleeve 4. A limiting ring 17 is inserted into the middle of the bottom of the herringbone plate 7 through a collar. Fixing blocks 18 are evenly arranged at the middle of the outer surface of the limiting ring 17. The end of the fixing block 18 away from the limiting ring 17 is fixedly installed on the side of the inner wall of the buffer ring 20. The herringbone plate 7 rotates on the surface of the limiting ring 17 under tension. The limiting ring 17 becomes the fulcrum of the herringbone plate 7, which facilitates the snap-fit ​​action of the snap-fit ​​block 6 on one side of the secondary snap-fit ​​sleeve 4.

[0025] Please see Figure 2 and Figure 3 A pressure plate 5 is slidably provided at the end of the herringbone plate 7 away from the snap-fit ​​block 6. There are two pressure plates 5, which are symmetrically arranged on both sides of one end of the herringbone plate 7. Both pressure plates 5 are sleeved on the outside of the vertical rod 8. With the pressure plates 5 on both sides of one end of the herringbone plate 7, the vertical rod 8 drives the pressure plates 5 to move, so that one end of the herringbone plate 7 can move in an arc around the center of the limiting ring 17. When moving in an arc, the disassembly and assembly of the secondary snap-fit ​​sleeve 4 can be realized.

[0026] Please see Figure 3 and Figure 4 The middle part of the pressure plate 5 is sleeved on the outer side of the top of the vertical rod 8. The bottom of the vertical rod 8 is rotatably provided with a threaded sleeve 9 via a bearing. A lead screw 15 is threaded into the bottom of the inner wall of the threaded sleeve 9. A ratchet 14 is fixedly sleeved on the outer circumferential surface of the bottom of the lead screw 15. The ratchet 14 is engaged with a locking plate 12 through its outer teeth. The middle part of the locking plate 12 is rotatably provided on the inner wall of the sliding groove of the inner wall of the rotating sleeve 1 via a rotating rod. A pressure rod 11 is fixedly provided on the top of the locking plate 12 at the end away from the ratchet 14. The pressure rod 11 extends to the outer side of the support sleeve 19. A limit plate 13 is slidably provided on the outer side of the locking plate 12 near the ratchet 14. The end of the limiting plate 13 away from the clamping plate 12 is fixedly set on the inner wall of the rotating sleeve 1. When the screw 15 rotates, it drives the ratchet 14 to move at the same time. The ratchet 14 moves inside the clamping plate 12. The clamping plate 12 engages with the teeth on the edge of the ratchet 14 to prevent the ratchet 14 from reversing after rotating a certain angle. When the screw 15 needs to reverse, the rotating sleeve 1 drives the screw 15 to rotate, and at the same time, the pressure rod 11 is pressed towards the center of the support sleeve 19, so that the clamping plate 12 disengages from the ratchet 14, making it easier for the screw 15 to rotate. The bottom of the screw 15 is rotatably set in the middle of the inner wall of the rotating sleeve 1.

[0027] Please see Figure 2 and Figure 3The length of the threaded sleeve 9 is greater than the height of the movement trajectory of the vertical rod 8 and the pressure plate 5. The length of the strip block on the outside of the sliding sleeve 16 is greater than the height of the outer limiting sleeve 10. When the screw 15 rotates, the threaded sleeve 9 moves up and down. The threaded sleeve 9 is prevented from rotating with the screw 15 by the strip block on the surface of the outer sliding sleeve 16. The sliding sleeve 16 is fixedly sleeved on the outside of the threaded sleeve 9. The outer side of the sliding sleeve 16 is provided with a strip block and is slidably sleeved with the outer limiting sleeve 10. The outer side of the outer limiting sleeve 10 is fixedly set in the middle of the inner wall of the conical sleeve 3.

[0028] The implementation principle of the quick separation and assembly structure of the power output assembly of a corn harvester according to the embodiments of this application is as follows: When installing the output assembly of the corn harvester, the main clamping plate 2 and the auxiliary clamping sleeve 4 are installed on the two assemblies respectively. The auxiliary clamping sleeve 4 is in contact with one end of the buffer ring 20. At this time, the vertical rod 8 drives the clamping block 6 to extend into the interior of the auxiliary clamping sleeve 4, causing the rotating sleeve 1 to rotate in one direction, causing the internal screw 15 to rotate. Since the top of the threaded sleeve 9 is provided with a bearing, under the action of the rotation of the screw 15, and the outer side of the sliding sleeve 16 on the outer side of the threaded sleeve 9 is provided with a strip block, the strip block is slidably connected to the inner wall groove of the outer limiting sleeve 10, the threaded sleeve 9 can only move up and down. The threaded sleeve 9 sleeved on the surface drives the vertical rod 8 to move up and down. When the vertical rod 8 moves upward, the pressure plate 5 lifts one end of the herringbone plate 7 upward. The middle part of the herringbone plate 7 is restricted by the limiting ring 17. The other end of the herringbone plate 7 drives the snap-fit ​​block 6 to move towards the bottom of the inner wall of the secondary snap-fit ​​sleeve 4. The snap-fit ​​block 6 tightly contacts the bottom of the secondary snap-fit ​​sleeve 4 with the top of the buffer ring 20, realizing the assembly of the components. When disassembly is required, the pressure rod 11 is pushed into the support sleeve 19, so that one end of the snap-fit ​​plate 12 is downward and the other end of the snap-fit ​​plate 12 is disengaged from the ratchet 14, which facilitates the reverse rotation of the screw 15. This achieves the effect of the upper snap-fit ​​block 6 being disengaged from the secondary snap-fit ​​sleeve 4, realizing rapid separation. This allows the operator to complete the power output switching in a short time, reducing equipment downtime and improving overall work efficiency. The rapid separation and assembly structure can reduce the fatigue and physical exertion of the operator due to improper force or long-term operation during installation and disassembly, making it easier for the operator to complete the maintenance and adjustment of the corn machine, improving work comfort and sustainability.

[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
