Description

Technical Field

[0001] This utility model relates to the field of tea planting technology, and in particular to a synchronous rotary mechanism. Background Technology

[0002] The slewing mechanism is the core functional mechanism in a mechanical system that enables specific components to perform continuous / intermittent slewing motion around a fixed or variable slewing centerline. Its core function is to provide stable constraints, controllable power, and precise attitude adjustment for the slewing components through the coordination of the drive device and the support device. At the same time, it can withstand vertical loads, horizontal loads, and overturning moments. It is widely used in scenarios such as lifting machinery, construction machinery, and automated equipment that require multi-directional operation or attitude transformation.

[0003] Existing equipment, such as CN217167737U, is a synchronous rotary mechanism. This synchronous rotary mechanism includes a base, on which a drive shaft assembly and a driven shaft assembly are fixedly mounted by screws. A drive shaft swing arm is mounted on the drive shaft assembly by screws, and a driven shaft swing arm is mounted on the driven shaft assembly by screws. The drive shaft swing arm and the driven shaft swing arm are connected by a linkage mechanism. This synchronous rotary mechanism achieves communication between the drive shaft swing arm and the driven shaft swing arm through a linkage mechanism, and is driven by the drive shaft assembly. Using a single drive mechanism, it can complete synchronous rotary operations. It has a simple structure, good synchronization effect, and can provide high support rigidity. It has a wide range of applications and a flexible structure.

[0004] The conventional design of existing synchronous rotary mechanisms uses two sets of drive motors. This approach cannot fully guarantee the synchronization between the two swing arms. If the drive motors have different drive speeds, deviations are likely to occur. Furthermore, the structure is complex, and the production cost of the device is high. Although the above solution solves this problem, the synchronization structure affects the rotation range of the swing arms, resulting in a reduction in the equipment's operating capacity. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the synchronization components in the existing technology affect the operating capacity of the equipment, and to propose a synchronous rotary mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a synchronous rotary mechanism, comprising a base plate, a mounting seat, a rotating shaft, a swing arm, and a synchronizing device. The mounting seat is fixedly connected to the upper surface of the base plate. Two sets of mounting seats are provided, and the two sets of mounting seats are symmetrically arranged. The rotating shaft is rotatably connected to the inner wall of the mounting seat. The swing arm is fixedly connected to the surface of the rotating shaft and is located on the back of the mounting seat. The synchronizing device is located on the rotating shaft. The synchronizing device includes a driving gear, which is fixedly connected to one end of one of the rotating shafts. A driven gear is fixedly connected to the surface of the other set of rotating shafts. A toothed belt is sleeved on the surface of the driving gear and the driven gear.

[0007] Furthermore, a motor is fixedly connected to the end of the rotating shaft away from the drive gear. The motor is located on the upper surface of the base plate and is fixedly connected to the front of the mounting base.

[0008] Furthermore, a limiting component is provided on the surface of the rotating shaft, the limiting component including a ratchet, which is fixedly connected to the surface of the rotating shaft.

[0009] Furthermore, a fixed shaft is fixedly connected to the back of the mounting base, and a pawl is rotatably connected to the surface of the fixed shaft, with the pawl abutting against the surface of the ratchet.

[0010] Furthermore, a magnet is fixedly connected to the upper surface of the pawl, and a mounting block is fixedly connected to the back of the mounting base.

[0011] Furthermore, an electromagnet is fixedly connected to the lower surface of the mounting block, and the electromagnet is positioned directly above the magnet.

[0012] Furthermore, there are two sets of limiting components, which are symmetrically arranged and have opposite limiting directions.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting a synchronization device, a single motor can drive two swing arms. The rotation process of the two swing arms is as follows: the motor drives one of the shafts to rotate, the driving gear and the shaft rotate simultaneously, the driving gear drives the driven gear to rotate simultaneously via a toothed belt, the driven gear drives the other shaft to rotate, and the two shafts drive the two swing arms to rotate simultaneously. When the swing arms rotate clockwise, the electromagnet on the left is activated first. The electromagnet, in conjunction with a magnet, lifts the pawl on the left, and then the motor is started, driving both swing arms to rotate clockwise. When the swing arms rotate counterclockwise, the electromagnet on the right is activated, and then the motor is started. By setting a synchronization device, the power of the single motor can be accurately and synchronously transmitted to the two swing arms. Compared with the traditional dual-motor drive scheme, this structure not only solves the problem of insufficient synchronization accuracy that is prone to occur with two sets of drive motors, but also avoids the limitation on the rotation range of the swing arms, thereby ensuring the multi-directional operation capability of the equipment and effectively improving the practicality of the equipment.

[0017] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a synchronous rotary mechanism, including a base plate 1, a mounting seat 2, a rotating shaft 3, a swing arm 4, and a synchronization device 5. The mounting seat 2 is fixedly connected to the upper surface of the base plate 1. There are two sets of mounting seats 2, which are symmetrically arranged. The rotating shaft 3 is rotatably connected to the inner wall of the mounting seat 2. The swing arm 4 is fixedly connected to the surface of the rotating shaft 3 and is located on the back of the mounting seat 2. The synchronization device 5 is located on the rotating shaft 3.

[0018] The specific setup and function of its synchronization device 5 will be explained below.

[0019] In this embodiment: the synchronization device 5 includes a drive gear 52, which is fixedly connected to one end of one of the rotating shafts 3. A driven gear 53 is fixedly connected to the surface of another set of rotating shafts 3. A toothed belt 54 is sleeved on the surface of the drive gear 52 and the driven gear 53.

[0020] The effect achieved by the above components is as follows: using the toothed belt 54 as the core transmission component of the synchronization device 5, when it is necessary to adjust the distance between the two swing arms 4, it is only necessary to replace the toothed belt 54 of the corresponding length specification to quickly complete the adaptation and adjustment of the synchronization system, so that the synchronization device 5 can be put back into use. The operation is convenient and the maintenance cost is low.

[0021] Please see Figure 1Specifically, a motor 51 is fixedly connected to the end of the rotating shaft 3 away from the drive gear 52. The motor 51 is located on the upper surface of the base plate 1 and is fixedly connected to the front of the mounting base 2.

[0022] Please see Figure 3 Specifically, a limiting component 55 is provided on the surface of the rotating shaft 3. The limiting component 55 includes a ratchet 551, which is fixedly connected to the surface of the rotating shaft 3.

[0023] Please see Figure 4 Specifically, a fixed shaft 552 is fixedly connected to the back of the mounting base 2, and a pawl 553 is rotatably connected to the surface of the fixed shaft 552, with the pawl 553 abutting against the surface of the ratchet 551.

[0024] The effect achieved by the above components is that the ratchet 551 and pawl 553 can provide support for the swing arm 4.

[0025] Please see Figure 4 Specifically, a magnet 554 is fixedly connected to the upper surface of the pawl 553, and a mounting block 555 is fixedly connected to the back of the mounting base 2.

[0026] Please see Figure 4 Specifically, an electromagnet 556 is fixedly connected to the lower surface of the mounting block 555, and the electromagnet 556 is positioned directly above the magnet 554.

[0027] The effect achieved by the above components is that by setting up magnet 554 and electromagnet 556, the engagement state between ratchet 551 and pawl 553 can be controlled.

[0028] Please see Figure 3 and Figure 5 Specifically, there are two sets of limit components 55, which are symmetrically arranged and have opposite limiting directions.

[0029] Working principle: By setting up a synchronization device 5, a single motor 51 can drive two swing arms 4. The process of the two swing arms 4 rotating is as follows: the motor 51 drives one of the rotating shafts 3 to rotate, the driving gear 52 and the rotating shaft 3 rotate simultaneously, the driving gear 52 drives the driven gear 53 to rotate simultaneously through the toothed belt 54, the driven gear 53 drives the other rotating shaft 3 to rotate, and the two rotating shafts 3 drive the two swing arms 4 to rotate simultaneously. When the swing arm 4 rotates clockwise, the electromagnet 556 on the left is activated first. The electromagnet 556, in conjunction with the magnet 554, lifts the pawl 553 on the left, and then the motor 51 is activated. The motor 51 drives the two swing arms 4 to rotate clockwise. When the swing arm 4 rotates counterclockwise, the electromagnet 556 on the right is activated, and then the motor 51 is activated.

[0030] By setting up a synchronization device 5, the power of a single motor 51 can be accurately and synchronously transmitted to the two swing arms 4. Compared with the traditional dual-motor 51 drive scheme, this structure not only solves the problem of insufficient synchronization accuracy that is prone to occur in two sets of drive motors 51, but also avoids the limitation on the rotation range of the swing arms 4, thereby ensuring the multi-directional operation capability of the equipment and effectively improving the practicality of the equipment.
