Description

Technical Field

[0001] This invention relates to the technical field of transplanters, and more particularly to a transplanter transmission mechanism and a transplanter that controls multiple mechanisms with a single power source. Background Technology

[0002] Transplanters, as core equipment for the efficient transfer and planting of materials or seedlings, are widely used in agricultural seedling transplanting, vegetable planting, and industrial material sorting and handling. Their operational efficiency and stability directly affect the continuity of the production process and the quality of the final output. In agricultural transplanting scenarios, transplanters need to complete a series of continuous actions such as digging holes, supplying seedlings, placing seedlings, and planting seedlings.

[0003] However, existing transplanters are becoming increasingly intelligent, typically employing a multi-power source design to control different actions. Each action mechanism (such as shoveling, planting, and feeding seedlings) is driven by an independent motor or hydraulic system. This multi-power source design results in bulky equipment with numerous components, complex wiring, low reliability, and increased manufacturing costs and maintenance difficulty. Because each power source operates independently, synchronization issues can easily arise between the actuators, leading to mismatches in the rhythm of shoveling, planting, and feeding seedlings during the planting process, impacting work efficiency and seedling survival rates.

[0034] Example 1

[0035] Reference Figure 1 and Figure 2 The first embodiment of the present invention provides a transplanter transmission mechanism, including a drive component 300 for providing a power source to maintain a constant rotational speed. Rotate;

[0036] The first transmission component 400 transmits the power of the drive component 300 to the movable shovel 503, thereby driving the movable shovel 503 in a first cycle. It oscillates back and forth, the first cycle , The transmission ratio of the first transmission component 400;

[0037] The second transmission component 600 transmits the power from the drive component 300 to the seedling plug 706, which operates in a second cycle. Perform reciprocating insertion and removal, second cycle Compared with the first cycle Synchronization, Second Cycle , The transmission ratio of the second transmission component 600; wherein, The value is a positive integer; the first transmission component 400 is provided with a phase adjustment element X for adjusting the first cycle. Compared to the second cycle The phase difference, so that the first cycle Actions and the second cycle The actions are matched in sequence.

[0038] in, The transmission ratio indicates the time required for the output shaft of the drive component 300 to rotate one revolution. = Z 从 / Z 主 Z 从 Z represents the number of teeth on the driven sprocket. 主 The number of teeth on the drive sprocket. This refers to the transmission ratio between the first transmission component 400 and the drive component 300. This refers to the transmission ratio between the second transmission component 600 and the drive component 300. To ensure that there is a first cycle That is The second cycle ,generally The value is 1.

[0039] It also includes a third transmission component 800, which is connected to the second transmission component 600 and transmits power to the seedling supply component 903 to drive the seedling supply component 903 in the second cycle. The third cycle of linkage To perform continuous movements; among them, = The second transmission component 600 and the third transmission component 800 share a central shaft 601, in the second cycle. Actions and the third cycle There is a fixed phase relationship between their actions.

[0040] The cycle refers to the time it takes for each actuator to complete one full action cycle. The cycle originates from the uniform rotational motion of the control motor 302, and is transmitted to each actuator through the drive rod 303 and various transmission components. The second cycle... The action refers to the seedling plug 706 completing one full cycle of insertion, lifting, and resetting; the third cycle The action refers to the distance that the seedling feeder 903 moves one station on the transmission chain 902. Since the second transmission component 600 and the third transmission component 800 share a central shaft 601, their movements originate from the same rotational motion, and therefore their phase relationship is fixed. Each time the seedling plug 706 is inserted to its lowest point and is ready to be lifted, one seedling feeder 903 moves to directly above the seedling plug 706 to prepare for seedling placement.

[0041] First cycle Defined by the first transmission component 400, the control motor 302 drives the first transmission rod 402 to rotate, which in turn drives the first eccentric wheel 404 to rotate, thereby driving the movable shovel 503 to perform reciprocating motions of lowering, raising, and resetting via the first connecting rod 406. Each rotation of the first eccentric wheel 404 completes one working cycle for the movable shovel 503.

[0042] Second cycle Defined by the second transmission component 600, the control motor 302 drives the central shaft 601 to rotate. The eccentric wheel 603 fixed on it converts the rotational motion into the reciprocating linear motion of the second connecting rod 604, which in turn drives the seedling plug 706 to perform reciprocating motion of falling, lifting, and resetting. Each rotation of the central shaft 601 completes one working cycle for the seedling plug 706.

[0043] Third cycle Defined by the third transmission component 800. Its power is directly derived from the second cycle. The central shaft 601. When the central shaft 601 rotates, it drives the rotary sprocket 901 through the third transmission sprocket 801 and the driven sprocket 802, so that the transmission chain 902 drives the seedling supply component 903 to move continuously. Each time the first cycle Second cycle To complete one cycle, the seedling component 903 moves one station's distance. Therefore, each time the seedling planting plug 706 completes one seedling planting cycle, it constitutes the second cycle. The seedling supply unit 903 moves one workstation to supply one seedling.

[0044] First cycle With the second cycle Although they share the same origin, they are not rigidly locked together. Their coordination is achieved through the phase adjustment component X. In terms of timing, the digging of holes is completed first, followed by the planting of seedlings, and one seedling is planted for each hole dug.

[0045] The second transmission component 600 and the third transmission component 800 are dynamically coupled via a shared central shaft 601. This mechanical rigid connection ensures the second cycle... With the third cycle A fixed transmission ratio and an unchangeable phase relationship are formed between them, i.e., forced synchronization. This avoids interference or decoupling between the two actions.

[0046] refer to Figure 3 The driving component 300 includes a control motor 302, and a drive rod 303 is provided at the output end of the control motor 302. The drive rod 303 is provided with several drive sprockets 304. Each period T ∝ 1 / ω, where T is the period, 1 is a complete cycle, and ω is the rotational speed of the control motor 302. That is, each period T is inversely proportional to the rotational speed ω of the control motor 302. When the motor speed ω increases, The value will decrease. This is due to the transmission ratio. and It is a fixed constant, therefore the period and The speed will also decrease proportionally, meaning the action will become faster. Conversely, when the motor speed ω decreases, the cycle time will increase. and It will increase proportionally, meaning the movement will slow down.

[0047] The drive unit 300 includes a mounting bracket 301, which is installed in the reserved space between the left and right vehicle bodies and connected and fixed to the vehicle body 200. A control motor 302 is mounted on one side of the mounting bracket 301. A drive rod 303 is located at the output end of the drive motor 102. Various transmission components are connected to the drive rod 303. When the control motor 302 rotates, it drives the drive rod 303 to rotate. The drive rod 303 simultaneously drives multiple actuators through various transmission components. Multiple drive sprockets 304 are arranged sequentially near the top of the drive rod 303, thereby driving the first transmission component 400 and the second transmission component 600 through the transmission structure of sprockets and chains. The transmission components then drive the actuators.

[0048] The top of the drive rod 303 of the drive component 300 is provided with two drive sprockets 304. One drive sprocket 304 is connected to the first transmission component 400, and the other drive sprocket 304 is connected to the second transmission component 600. The second transmission component 600 is also provided with an additional sprocket for connection with the third transmission component 800. At this time, the control motor 302 of the drive component 300 can control the operation of the three transmission components simultaneously by controlling the rotation of the drive rod 303. Furthermore, as needed, more sprockets and chains can be added to synchronously drive more transmission components.

[0049] Since the various components are connected by sprockets and chains, the speed and force of the final actuator in each rotation cycle can be changed simply by adjusting the gear ratio between the sprockets of the first transmission component 400, the second transmission component 600, the third transmission component 800, and the drive component 300. For example, by increasing the radius of the sprocket of the transmission component to be larger than that of the sprocket of the drive component 300, the speed of the final actuator can be slowed down and the force increased. When the radius of the sprocket of the transmission component is equal to that of the sprocket of the drive component 300, the two rotate synchronously. When the radius of the sprocket of the transmission component is smaller than that of the sprocket of the drive component 300, the speed of the final actuator increases and the force decreases.

[0050] Example 2

[0051] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that: the first transmission component 400 includes a fixed frame 401 mounted on the vehicle body 200, a first transmission rod 402 rotatably connected to the fixed frame, a first transmission sprocket 403 provided on the first transmission rod 402, the other end of which is connected to a phase adjustment component X, and the first transmission sprocket 403 is connected to a drive sprocket 304; the phase adjustment component X includes a first eccentric wheel 404 provided at one end of the first transmission rod 402, and a plurality of positioning holes 405 formed on the circumferential surface of the first eccentric wheel 404; a first connecting rod 406, one end of which is connected to one of the positioning holes 405, and the other end of which is connected to a first connecting frame 407.

[0052] Among them, reference Figure 4 and Figure 5 The first eccentric wheel 404 of the phase adjustment component X is disc-shaped, and the distance between each positioning hole 405 and the center of the disc is different, thereby achieving the eccentric effect. The first connecting rod 406 and the positioning hole 405 can be fixed by bolts and nuts, pins, etc., as long as the top of the first connecting rod 406 can be installed in the positioning hole 406 and can rotate relative to the first eccentric wheel 404. In this embodiment, by connecting the first connecting rod 406 to different positioning holes 405, the installation position between the first connecting rod 406 and the first eccentric wheel 404 is changed, thereby changing the starting phase of the action cycle of the first actuator 500.

[0053] Example 3

[0054] The third embodiment of the present invention differs from the previous embodiment in that: the first transmission component 400 includes a fixed frame 401 mounted on the vehicle body 200, a first transmission rod 402 rotatably connected to the fixed frame, a first transmission sprocket 403 provided on the first transmission rod 402, the first transmission sprocket 403 being connected to the drive sprocket 304, and a phase adjustment element X provided at one end of the first transmission rod 402; the phase adjustment element X includes a first eccentric wheel 404 provided at one end of the first transmission rod 402.

[0055] The first eccentric wheel 404 of the phase adjustment component X can also be configured as an eccentric wheel with adjustable eccentricity. For example, an adjustable eccentricity eccentric wheel can be referred to in CN103133512B, or any other structure that can change the eccentric end of the eccentric wheel. The top end of the first connecting rod 406 is rotatably connected to the eccentric end of the first eccentric wheel 404. In this embodiment, by adjusting the eccentricity of the eccentric wheel itself, the installation position of the first connecting rod 406 is changed, thereby changing the starting phase of the action cycle of the first actuator 500.

[0056] Example 4

[0057] refer to Figure 6 This is the fourth embodiment of the present invention. The difference between this embodiment and the previous embodiment is that: the first transmission component 400 includes a fixed frame 401 mounted on the vehicle body 200, a first transmission rod 402 rotatably connected to the fixed frame, a first transmission sprocket 403 provided on the first transmission rod 402, the first transmission sprocket 403 being connected to the drive sprocket 304, and a phase adjustment component X provided at one end of the first transmission rod 402; the phase adjustment component X includes a first eccentric wheel 404 provided at one end of the first transmission rod 402.

[0058] The phase adjustment component X can also be provided with a disc-shaped first eccentric wheel 404. A sliding rod 408 is provided on the surface of the first eccentric wheel 404 from the center outward. A connecting seat 409 is slidably connected to the sliding rod 408. The surface of the first eccentric wheel 404 is provided with mounting holes corresponding to the sliding rod 408 and the connecting seat 409. The connecting seat 409 is also provided with corresponding connecting holes. One end of the first connecting rod 406 is rotatably connected to the connecting seat 409. In this embodiment, by adjusting the position of the connecting seat 409 on the sliding rod 408, the installation position between the first connecting rod 406 and the first eccentric wheel 404 is changed, thereby changing the starting phase of the action cycle of the first actuating component 500.

[0059] Example 5

[0060] refer to Figure 7The second transmission component 600 includes a central shaft 601 rotatably connected to the vehicle body 200. A second transmission sprocket 602 connected to the drive sprocket 304 is provided on the central shaft 601. A second eccentric wheel 603 is also provided on the central shaft 601. A second connecting rod 604 is rotatably connected to the eccentric end of the second eccentric wheel 603. One end of the second connecting rod 604 is movably connected to a limiting rod 605 provided on the vehicle body 200 to limit its swing trajectory. The rotational motion of the central shaft 601 is converted into the reciprocating linear motion of the second actuating component 700 through the second eccentric wheel 603 and the second connecting rod 604.

[0061] The top end of the central shaft 601 is provided with a second transmission sprocket 602, which is the same as the drive sprocket 304. It can be connected by a chain, so that the drive motor 102 can drive the central shaft 601 to rotate. The other end of the central shaft 601 is provided with a second eccentric wheel 603. When the central shaft 601 rotates, it drives the second eccentric wheel 603 to rotate. One end of the second connecting rod 604 is rotatably connected to the eccentric end of the second eccentric wheel 603. At this time, the second eccentric wheel 603 can control the swing of the second connecting rod 604. The surface of the second connecting rod 604 is provided with a limiting through groove that is connected to the end of the limiting rod 605. One end of the limiting rod 605 is inserted into the through groove, and the other end is fixed to the vehicle body 200, thereby limiting the angle of the second connecting rod 604 itself. The limiting rod 605 can both rotate and slide in the through groove of the second connecting rod 604.

[0062] The first eccentric wheel 404 is an eccentric wheel with adjustable eccentricity in different gears; while the second eccentric wheel 603 is a conventional eccentric wheel.

[0063] By configuring the gear ratio between the drive sprocket 304 and the first transmission sprocket 403 and the second transmission sprocket 602, the movement speed and output torque of each actuator can be adjusted independently. For example, increasing the number of teeth on the transmission sprocket can reduce the speed and increase the torque to meet the high torque required for shoveling.

[0064] refer to Figure 7 and Figure 8 The third transmission component 800 includes a third transmission sprocket 801 disposed on the central shaft 601; and a driven sprocket 802 connected to the third transmission sprocket 801; wherein the rotational motion of the central shaft 601 is converted into a vertical rotational output through the third transmission sprocket 801 and the driven sprocket 802 to drive the third actuation component 900.

[0065] By additionally setting a third transmission sprocket 801 on the central shaft 601, the third transmission sprocket 801 and the driven sprocket 802 are also driven by a chain, so that when the second transmission component 600 rotates, the third transmission component 800 can be driven to rotate at the same time. The driven sprocket 802 converts the power into vertical upward through a helical gear or other structure that can achieve this function, and then connects to the third actuating component 900.

[0066] The drive component 300, the first transmission component 400, the second transmission component 600, and the third transmission component 800 are all equipped with sprockets and connected by chains. Since chains and sprockets are conventional existing technology, the chains are hidden in the diagram for ease of illustration.

[0067] The remaining structure is the same as that in Example 1.

The first transmission sprocket 403 drives the first transmission rod 402 to rotate. The first transmission rod 402 drives the first eccentric wheel 404 to rotate. When the first eccentric wheel 404 rotates, it drives the first connecting rod 406 to swing. When the first eccentric wheel 404 rotates and drives the first connecting rod 406 to rise, the first connecting rod 406 pulls up the swing rod 502, which can lift the movable shovel 503. When the first eccentric wheel 404 drives the first connecting rod 406 to fall, the first connecting rod 406 presses down the swing rod 502, which can lower the movable shovel 503 and insert it into the soil.

[0078] The second execution component 700 includes a fixed shaft 701 mounted on the vehicle body 200; a fixed rod 702 rotatably connected to the fixed shaft 701; a transition piece 703 rotatably connected to the end of the fixed rod 702 away from the fixed shaft 701; a connecting rod 704 rotatably connected to the transition piece 703; a second connecting frame 705 rotatably connected to the end of the connecting rod 704 away from the transition piece 703; and a seedling plug 706 disposed on the second connecting frame 705.

[0079] The second connecting rod 604 is rotatably connected to the connecting rod 704, and the second transmission component 600 drives the seedling plug 706 to perform reciprocating seedling planting action.

[0080] A fixed shaft 701 is mounted on the vehicle body 200. A sleeve is fitted onto the fixed shaft 701. A fixed rod 702 is rotatably connected to the fixed shaft 701 through the sleeve. Several parallel fixed rods 702 are provided on the outer side of the sleeve. At least two fixed rods 702 are provided. A connector 703 is rotatably connected to the end of the fixed rod 702 away from the sleeve. The connector 703 is composed of several non-rotating rods. Plates are provided at both ends for fixing and limiting. The connector 703 has at least four non-rotating rods, of which at least two are used to rotatably connect with the fixed rods 702 to keep the fixed rods 702 parallel to each other. The remaining rods are rotatably connected to several parallel connecting rods 704. The other end of each connecting rod 704 is rotatably connected to a second connecting frame 705. The second connecting frame 705 is used to install the seedling plug 706. The end of the second connecting rod 604 furthest from the second eccentric wheel 603 is rotatably connected to the connecting rod 704. When the second eccentric wheel 603 rotates, it drives the second connecting rod 604 to move up and down. At this time, the position of the second connecting rod 604 is restricted by the limiting rod 605, preventing the bottom end of the second connecting rod 604 from wobbling. The second connecting rod 604 can then periodically swing up and down with the second eccentric wheel 603, thereby driving the connecting rod 704 to swing up and down, controlling the periodic up and down movement of the seedling plug 706.

[0081] Since both the first transmission component 400 and the second transmission component 600 are connected to the drive sprocket 304 of the drive component 300 through the transmission sprocket, the drive motor 102 will simultaneously control the movable shovel 503 and the seedling plug 706 to move up and down periodically. By connecting the movable shovel 503 to different positioning holes 405, the activity cycle of the movable shovel 503 can be adjusted so that it can be adapted to the seedling plug 706, thereby realizing the automatic periodic operation of digging holes and planting seedlings.

[0082] refer to Figure 11 and Figure 12 The third actuating component 900 includes two sprockets 901 disposed on the vehicle body 200; a transmission chain 902 wound around the two sprockets 901; and a seedling supply component 903 fixed on the transmission chain 902.

[0083] In this system, a rotary sprocket 901 is connected to a driven sprocket 802, and a third transmission component 800 drives the rotary sprocket 901 to rotate. The seedling supply component 903 moves with the transmission chain 902 to achieve uninterrupted seedling supply.

[0084] By additionally setting a third transmission sprocket 801 on the central shaft 601, the third transmission sprocket 801 and the driven sprocket 802 are also driven by a chain, so that when the second transmission component 600 rotates, it can simultaneously drive the third transmission component 800 to rotate. The driven sprocket 802 converts the power into vertical upward force through a helical gear or other structure that can achieve this function, and then connects to the rotary sprocket 901 of the third actuator 900. The rotary sprocket 901 is also connected to the vehicle body 100 or the vehicle body 200 to fix the rotary sprocket 901. At position 1, the control motor 302 drives the first actuator 500 and the second actuator 700 to move cyclically, while simultaneously driving the rotary sprocket 901 of the third actuator 900 to rotate. The two rotary sprockets 901 are driven by the transmission chain 902, so that the two rotary sprockets 901 rotate synchronously. The inner wall of the transmission chain 902 meshes with the rotary sprockets 901, and the outer surface is fixedly connected to several seedling supply components 903, thereby driving the seedling supply components 903 to rotate and supply seedlings. The seedling supply components 903 can deliver seedlings into the seedling plug 706.

[0085] The seedling supply component 903 consists of multiple funnels installed on the outer surface of the transmission chain 902. A seedling outlet is provided directly above the seedling plug 706. Whenever a funnel passes through the seedling outlet, the seedling inside the funnel will fall into the seedling plug 706 for the seedling plug 706 to plant.

[0086] By adjusting the diameter of the first eccentric wheel 404, the position of the positioning hole 405, the eccentric position of the second eccentric wheel 603, and the diameter of the sprocket 901, the movable shovel 503, the seedling plug 706, and the seedling supply component 903 can be aligned to the same cycle. This ensures that each time the movable shovel 503 falls, the seedling plug 706 also falls, and the seedling supply component 903 supplies seedlings after the seedling plug 706 rises. Combined with an appropriate vehicle body 100 moving speed, one drive component 300 can simultaneously drive multiple actuators, and actuators can be added as needed, with the cycles of each actuator matched.

[0087] The remaining structure is the same as that in Example 5.
