Description

Technical Field

[0001] The utility model relates to the technical field of seeders, and specifically to a power switching clutch mechanism for a seeding monomer of a seeder. Background Technique

[0002] With the continuous development of agricultural technology, modern agriculture pays more and more attention to the rational utilization of resources and environmental protection. In seeding operations, in order to save seed resources, reduce unnecessary energy consumption and improve seeding accuracy, people begin to focus on how to carry out refined management of each seeding unit on the seeder. Especially during field operations, when encountering areas where seeding is not required or situations where seeding density needs to be adjusted, the power input to certain seeding units can be cut off to achieve precise seeding. For this reason, existing seeding monomers are usually equipped with a power switching clutch mechanism to facilitate cutting off or restoring the power supply of the seeding unit when necessary.

[0003] However, most traditional clutches on the market currently have certain defects. First of all, the cost is relatively high, mainly due to their complex manufacturing process and expensive materials; secondly, due to the structural design, these clutches are often relatively large in size and occupy more space; furthermore, due to bearing a large load and frequent operations for a long time, the components of traditional clutches are prone to wear, which not only affects their service life but also increases the cost of maintenance and replacement. The performance degradation caused by wear may also affect seeding accuracy and efficiency, thus having an adverse impact on the growth of crops. No effective solution has been proposed for the problems in the related technology. Content of the Utility Model

[0004] Aiming at the problems in the related technology, the utility model proposes a power switching clutch mechanism for a seeding monomer of a seeder to overcome the above-mentioned technical problems existing in the existing related technology.

[0005] For this reason, the specific technical solution adopted by the utility model is as follows:

[0006] A power switching clutch mechanism for a seeding monomer of a seeder includes a connecting shaft. A first transmission bearing is fixedly installed on the surface of the connecting shaft. A transmission sprocket is fixedly connected to the surface of the first transmission bearing. A rotation groove is formed on one end surface of the connecting shaft. A limiting retaining ring is rotatably installed outside the rotation groove. A clutch spring is fixedly connected to one side of the limiting retaining ring. The end of the clutch spring is fixedly connected to an adjusting clamping plate. The central hole of the adjusting clamping plate is matched with the outer surface of the connecting shaft. An adjusting groove is formed on one side surface of the connecting shaft. A transmission groove is formed on one side surface of the transmission sprocket. A limiting block is fixedly connected to the outer surface of the adjusting clamping plate. The limiting block is matched with the transmission groove.

[0007] Further, in order to rotatably mount the connecting shaft, a second transmission bearing is fixedly installed on one side of the outer surface of the connecting shaft. The outer side of the second transmission bearing is fixedly connected to a stamping diamond seat, and bearing seats are fixedly installed at both ends of the stamping diamond seat through bolts.

[0008] Further, in order to provide power for the seeding unit of the seeder when the connecting shaft is sowing, an installation hole is opened inside the connecting shaft.

[0009] Further, in order to removably replace the adjusting card plate, a snap ring is rotatably installed inside the rotating groove, and the snap ring is fixedly connected to the limit retaining ring through bolts.

[0010] Further, in order to facilitate the adjustment of the position of the adjusting card plate, two sides of the surface of the adjusting card plate are fixedly connected with screwing blocks, and the size of the screwing blocks is matched with the transmission groove.

[0011] Further, in order to fixedly install the bearing seat on the seeding unit of the seeder, positioning holes are opened at both ends of the bearing seat.

[0012] Further, in order to limit the first transmission bearing on the connecting shaft, wire retaining rings are fixedly installed on both sides of the first transmission bearing on the connecting shaft.

[0013] The beneficial effects of the present utility model are as follows: By rotating and sliding the adjusting card plate on the connecting shaft, the limiting block on the adjusting card plate is engaged with and separated from the transmission groove, and the central hole of the adjusting card plate is engaged with and separated from the connecting shaft, so that when the transmission sprocket rotates, the driving of the connecting shaft can be freely adjusted, thereby realizing power switching. The clutch mechanism has a simple structure and convenient operation. Only before sowing, manually rotate and slide the adjusting card plate to adjust its position on the connecting shaft, and the free adjustment of the clutch state of the seeding unit can be realized. Moreover, the matching transmission mode of the adjusting card plate with the connecting shaft and the transmission sprocket can effectively reduce wear and extend the service life of the clutch mechanism.

[0022] According to an embodiment of the present invention, a seeding unit power switching clutch mechanism of a seeding machine is provided.

[0023] Embodiment 1:

[0024] Such as Figures 1-4As shown in the figure, a power switching clutch mechanism for a seeding unit of a seeder according to an embodiment of the present utility model includes a connecting shaft 1 made of cemented carbide. A transmission bearing one 2 is fixedly installed on the surface of the connecting shaft 1. This bearing is a deep groove ball bearing. A transmission sprocket 3 is fixedly connected to the surface of the transmission bearing one 2, and is used for the seeder to rotate through the chain belt driving the transmission sprocket 3. A rotation groove 4 is formed on one end surface of the connecting shaft 1. A limit retaining ring 5 is rotatably installed outside the rotation groove 4. A clutch spring 6 is fixedly connected to one side of the limit retaining ring 5. The end of the clutch spring 6 is fixedly connected to an adjustment clamping plate 7. The adjustment clamping plate 7 is slidably installed on the outer surface of the connecting shaft 1, and the central hole of the adjustment clamping plate 7 is matched with the outer surface of the connecting shaft 1. An adjustment groove 8 is formed on the connecting shaft 1 near the adjustment clamping plate 7. Two pairs of transmission grooves 9 are formed on the surface of the transmission sprocket 3 near the adjustment groove 8. A limit block 10 is fixedly connected to the outer surface of the adjustment clamping plate 7, and the limit block 10 is matched with the transmission groove 9.

[0025] As Figures 1-4 As shown in the figure, a transmission bearing two 11 is fixedly installed on the outer surface of the connecting shaft 1 away from the adjustment clamping plate 7. A stamping diamond seat 12 is fixedly connected to the outside of the transmission bearing two 11. Both ends of the stamping diamond seat 12 are fixedly installed with bearing seats 13 through bolts. Positioning holes 17 are formed at both ends of the bearing seats 13, and are used to fixedly install the whole clutch mechanism on the seeding unit through bolts. An installation hole 14 is formed inside the connecting shaft 1, and is used to connect the connecting shaft 1 with the seeder on the seeding unit to provide power for it during rotation. An elastic retaining ring 15 is rotatably installed inside the rotation groove 4. The elastic retaining ring 15 is fixedly connected to the limit retaining ring 5 through bolts. By disassembling the elastic retaining ring 15, the disassembly and replacement of the adjustment clamping plate 7 on the connecting shaft 1 are realized. Turning blocks 16 are fixedly connected to both sides of the surface of the adjustment clamping plate 7. The size of the turning blocks 16 is matched with the transmission groove 9, and is used to conveniently adjust the position of the adjustment clamping plate 7 on the connecting shaft 1 through the turning blocks 16. Steel wire retaining rings 18 are fixedly installed on both sides of the transmission bearing one 2 on the connecting shaft 1, and are used to block and limit the transmission bearing one 2 on the connecting shaft 1.

[0026] In order to facilitate the understanding of the above technical solution of the present utility model, the working principle or operation method of the present utility model in the actual process will be described in detail below.

[0027] In summary, by means of the above technical solution of the present utility model, during actual use, when the seeder on the seeding unit needs the connecting shaft 1 to provide power for seeding, by rotating and sliding the adjusting clamping plate 7 on the connecting shaft 1, when the central hole of the adjusting clamping plate 7 is matched with the connecting shaft 1, then the limiting block 10 and the screwing block 16 on the adjusting clamping plate 7 are cooperatively installed in the transmission groove 9 on one side of the transmission sprocket 3. Furthermore, when the transmission sprocket 3 rotates, the adjusting clamping plate 7 is driven to rotate through the limiting block 10 and the screwing block 16. The adjusting clamping plate 7 drives the connecting shaft 1 to rotate through the cooperation of the central hole and the connecting shaft 1, providing power for the seeding of the seeder. When the seeding unit does not need to perform seeding, the adjusting clamping plate 7 is slid into the adjusting groove 8 on the surface of the connecting shaft 1, and the adjusting clamping plate 7 is rotated so that its central hole no longer cooperates with the connecting shaft 1. At this time, after the transmission sprocket 3 rotates, it can only drive the first transmission bearing 2 to rotate and cannot continue to drive the connecting shaft 1 to transmit power, thereby realizing power switching and making the seeding unit no longer perform seeding.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
