Description

Technical Field

[0001] This utility model relates to the field of clutch transmission technology, and in particular to a clutch transmission mechanism for a seeder. Background Technology

[0002] Seeders are indispensable equipment in modern agricultural mechanization, and their main function is to evenly spread seeds into the soil. Traditional seeders usually use a fixed transmission mechanism, with the engine directly driving the seeding operation. However, in actual operation, the power system of the seeder often needs to be adjusted according to field conditions and seeding needs, such as disconnecting or engaging the transmission link between the engine and the gearbox to allow for idling or gear shifting operations.

[0003] Traditional transmission mechanisms are complex in design and inconvenient to adjust. During transmission, the rigid connection of the transmission chain can easily cause wear of mechanical parts, reducing the service life of the equipment. At the same time, existing clutch mechanisms often lack precise limit devices, resulting in unstable clutch operation, which can easily lead to misoperation or transmission failure, thus affecting the working efficiency of the seeder.

[0004] Therefore, we propose a seeder clutch transmission mechanism to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a clutch transmission mechanism for a seeder.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seeder clutch transmission mechanism, comprising a drive shaft, a gearbox shaft, and a movable bushing. One end of the drive shaft is provided with a gear, and the middle of the gearbox shaft is provided with a gear disk. The gear disk is provided with tooth grooves, which mesh with the gear. The gear disk is provided with a fixed opening. The movable bushing is slidably mounted on the gearbox shaft through a limiting component. One end of the movable bushing is provided with a movable opening, the position and shape of which are adapted to the fixed opening. A power component is rotatably provided on the outer wall of the movable bushing.

[0007] Preferably, the limiting component consists of a female opening, a limiting block, a bolt, and a limiting groove. The female opening is symmetrically opened on the outer wall of the gearbox shaft. The limiting block is movably inserted into the female opening. One end of the bolt presses against the limiting block, and the other end of the bolt is threaded inside the female opening.

[0008] Preferably, the limiting grooves are symmetrically formed on the inner wall of the movable bushing, and the portion of the limiting block protruding from the gearbox shaft is slidably inserted into the limiting grooves.

[0009] Preferably, a retaining ring is provided at the end of the gearbox shaft by means of a screw, and the movable bushing is located between the fixed opening and the retaining ring.

[0010] Preferably, the power assembly consists of a drive ring, a connecting hole, and a wing arm, with the drive ring rotatably disposed on the outer wall of the movable bushing.

[0011] Preferably, the two wing arms are symmetrically arranged on the drive ring, and the connecting holes are formed on the wing arms.

[0012] Preferably, the outer wall of the movable bushing is provided with an annular groove that is adapted to the drive ring, and the drive ring is rotatably mounted on the annular groove.

[0013] Preferably, the outer wall of the end of the gearbox shaft away from the movable bushing is provided with a spline.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] During use, the clutch transmission mechanism of this utility model can connect the drive shaft to the engine of the seeder and the gearbox shaft to the gearbox of the seeder. The clutch operating end is connected through the connecting hole of the upper wing arm of the drive ring. The engine drives the drive shaft to rotate.

[0016] When the engine and transmission are separated, the movable sleeve moves away from the gear plate under the action of the clutch operating end. At this time, the fixed port on the gear plate and the movable port on the movable sleeve are separated from each other. Then the rotation of the drive shaft acts on the gear plate, causing the gear plate to rotate freely without affecting the transmission shaft.

[0017] When the engine and transmission are engaged, under the action of the clutch operating end, the movable sleeve approaches the gear plate. At this time, the fixed port on the gear plate and the movable port on the movable sleeve are inserted and matched. Then the rotation of the drive shaft acts on the gear plate to drive the gear plate to rotate. The rotation of the gear plate drives the movable sleeve to rotate, and the movable sleeve drives the transmission shaft to rotate.

[0018] The clutch transmission mechanism can control the position of the movable sleeve through the clutch operating end, so as to achieve precise separation and engagement of power between the engine and the gearbox. When separated, the fixed port on the gear plate separates from the movable port on the movable sleeve, and the rotation of the drive shaft only acts on the gear plate without affecting the gearbox shaft, ensuring stable idling. When engaged, the fixed port and the movable port match, and the power is efficiently transmitted to the gearbox shaft, thereby realizing the normal operation of the seeder.

[0019] By designing the limiting components and the sliding connection between the limiting block and the limiting groove, the movable bushing can only slide on the gearbox shaft, and there is no relative rotation between the movable bushing and the gearbox shaft. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figures 1-5 As shown, the present invention proposes a seeder clutch transmission mechanism, including a drive shaft 1, a gearbox shaft 2, and a movable bushing 3. One end of the drive shaft 1 is provided with a gear 6, and the middle of the gearbox shaft 2 is provided with a gear disk 4. The gear disk 4 is provided with a tooth groove 5, and the tooth groove 5 and the gear 6 mesh with each other. The gear disk 4 is provided with a fixed opening 14. The movable bushing 3 is slidably disposed on the gearbox shaft 2 through a limiting component. One end of the movable bushing 3 is provided with a movable opening 12, and the position and shape of the movable opening 12 and the fixed opening 14 are adapted to each other. The outer wall of the movable bushing 3 is provided with a power component.

[0030] Based on Example 1:

[0031] During use, the clutch transmission mechanism of this utility model can connect the drive shaft 1 to the engine of the seeder and the gearbox shaft 2 to the gearbox of the seeder. The clutch operating end is connected through the connecting hole 15 of the upper wing arm 16 of the drive ring 7. The engine drives the drive shaft 1 to rotate.

[0032] When the engine and gearbox are separated, the movable sleeve 3 moves away from the gear plate 4 under the action of the clutch operating end. At this time, the fixed port 14 on the gear plate 4 and the movable port 12 on the movable sleeve 3 are separated from each other. Then the rotation of the drive shaft 1 acts on the gear plate 4, causing the gear plate 4 to rotate freely without affecting the gearbox shaft 2.

[0033] When the engine and gearbox are engaged, under the action of the clutch operating end, the movable bushing 3 approaches the gear plate 4. At this time, the fixed port 14 on the gear plate 4 and the movable port 12 on the movable bushing 3 are inserted and matched. Then the rotation of the drive shaft 1 acts on the gear plate 4 to drive the gear plate 4 to rotate. The rotation of the gear plate 4 drives the movable bushing 3 to rotate, and the movable bushing 3 drives the gearbox shaft 2 to rotate.

[0034] The clutch transmission mechanism can control the position of the movable sleeve 3 through the clutch operating end, so as to achieve precise separation and engagement of power between the engine and the gearbox. When separated, the fixed port 14 on the gear plate 4 separates from the movable port 12 on the movable sleeve 3. The rotation of the drive shaft 1 only acts on the gear plate 4 and does not affect the gearbox shaft 2, ensuring stable idling. When engaged, the fixed port 14 and the movable port 12 match, and the power is efficiently transmitted to the gearbox shaft 2, thereby realizing the normal operation of the seeder.

[0035] Due to the design of the limiting component, the movable bushing 3 and the gearbox shaft 2 cannot rotate relative to each other.

[0036] Example 2

[0037] like Figures 1-5 As shown, the present invention proposes a seeder clutch transmission mechanism. Compared with Embodiment 1, this embodiment further includes: a limiting component consisting of a female opening 9, a limiting block 10, a bolt 11, and a limiting groove 13. The female opening 9 is symmetrically opened on the outer wall of the gearbox shaft 2. The limiting block 10 is movably inserted into the female opening 9. One end of the bolt 11 presses against the limiting block 10, and the other end of the bolt 11 is threaded into the female opening 9. The limiting groove 13 is symmetrically opened on the inner wall of the movable bushing 3. The part of the limiting block 10 protruding from the gearbox shaft 2 is slidably inserted into the limiting groove 13. Through the design of the limiting component and the sliding connection design between the limiting block 10 and the limiting groove 13, the movable bushing 3 can only slide on the gearbox shaft 2. The movable bushing 3 and the gearbox shaft 2 cannot rotate relative to each other, ensuring the reliability of the transmission system. The sliding connection design between the limiting block 10 and the limiting groove 13 effectively avoids the movable bushing 3 from shifting position or making operational errors under high load.

[0038] A retaining ring 8 is provided at the end of the gearbox shaft 2 by screws, and the movable bushing 3 is located between the fixed port 14 and the retaining ring 8. The movement trajectory of the movable bushing 3 is limited by the above description.

[0039] The power assembly consists of a drive ring 7, a connecting hole 15, and two wings 16. The drive ring 7 is rotatably mounted on the outer wall of the movable bushing 3. Two wings 16 are symmetrically arranged on the drive ring 7. The connecting hole 15 is formed on the wing 16. The outer wall of the movable bushing 3 has an annular groove that matches the drive ring 7. The drive ring 7 is rotatably mounted on the annular groove. The clutch operating end is connected through the connecting hole 15 of the wing 16 on the drive ring 7.

[0040] The outer wall of the end of the gearbox shaft 2 away from the movable bushing 3 is provided with a spline, which facilitates the connection between the gearbox shaft 2 and the external structure.

[0041] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
