Description

Technical Field

[0001] This invention relates to the field of agricultural intelligent equipment technology, and in particular to a fully automatic transplanter tray conveying and recycling device and its usage method. Background Technology

[0002] In current agricultural crop production, traditional seedling tray conveying methods generally suffer from the inability to continuously circulate, resulting in a large distance between the tray delivery position and the stacking position. This necessitates manual operation and severely affects the efficiency of automated transplanting operations.

[0003] Therefore, it is necessary to provide a new fully automatic transplanter tray conveying and recycling device and its usage method to solve the above-mentioned technical problems. Summary of the Invention

[0004] To address the problems inherent in traditional seedling tray conveying methods, such as the inability to continuously circulate the trays, resulting in significant distances between the tray delivery and stacking positions, necessitating manual operation and severely impacting the efficiency of automated transplanting operations, this invention provides a fully automatic transplanting machine tray conveying and recycling device and its usage method.

[0005] The fully automatic transplanter tray conveying and recycling device provided by this invention includes: a frame structure, on which a steel frame is provided; a front fixed frame and a rear fixed frame are installed on the frame structure; a front base fixing bolt and a rear base fixing bolt are respectively provided on the front fixed frame and the rear fixed frame; pulleys 1, 2, 3, 4, 5, 7, 8, 9, 10, and 11 are provided on the frame structure for transmission; a tray feeding device is provided on the frame structure for providing a tray conveying channel; a one-way tray supply mechanism is provided on the frame structure for conveying trays; a one-way output valve, a reversing track, a tray discharge track, and a tray stacking device are provided on the frame structure; and a seedling lifting device is installed on the frame structure for assisting in lifting the seedling clump, wherein the seedling lifting device has a seedling lifting structure inside.

[0006] Preferably, the tray feeding track is provided with a drive shaft structure, which includes drive shaft one, drive shaft two, drive shaft three, drive shaft four, drive shaft five, drive shaft six, drive shaft seven, drive shaft eight and drive shaft nine. Drive shaft four is the main power source used for belt drive to link the other drive shafts. The tray stacking device includes sensor one, sensor two and sensor three, electromagnet, tray stacking box and lever structure. The tray stacking box is fixed to the frame structure by the steel frame and is driven by the lever structure and the tray stacking box for accommodating seedling trays by the electromagnet. The lever structure is used to assist the seedling trays to fall into the tray stacking box under the action of gravity to achieve automatic stacking.

[0007] Preferably, a motor for driving a one-way tray feeding mechanism is provided on one side of the tray feeding device, a one-way output valve is provided at the junction of the tray feeding device and the reversing track, the motor is located on one side of the reversing track, and the tray exit track is driven by a drive wheel to drive the drive shaft six to achieve intermittent pushing. The power source of the tray exit track is a ratchet and pawl mechanism driven by a cylinder. The ratchet and pawl mechanism is set on the one-way tray feeding mechanism. The ratchet and pawl mechanism includes an inner ratchet wheel rotatably mounted on the tray feeding device, a pawl slider for locking the inner ratchet wheel, a first spring mounted on the pawl slider, and a rotating shaft bottom baffle fixed on the first spring. Rotating shaft side baffles for stabilizing the pawl slider are provided on both sides of the pawl slider. An alarm for prompting tray replenishment is provided on one side of the tray feeding device, and the tray stacking device is located at the end of the tray exit track.

[0008] Preferably, the tray feeding device is set in an inclined state, and the tray feeding device is provided with a seedling tray for holding the seedling clump, and the seedling tray slides down by its own weight and connects to the drive shaft seven.

[0009] Preferably, the reversing track is set in an inclined state, the motor can reverse to drive the drive shaft 8 to rotate, and the seedling tray can slide down the reversing track onto the drive shaft 6 through the combined action of its own kinetic energy and gravitational inertia, so as to realize intermittent tray feeding.

[0010] Preferably, the frame structure is provided with a speed-changing gear device for driving the seedling device at different speeds. The speed-changing gear device includes a drive shaft and a gear. The drive shaft and gear are used to drive the camshaft to extend and retract the seedling. A connecting rod is installed on the seedling, and a second spring is sleeved on the connecting rod to assist the seedling in resetting.

[0011] This invention also provides a method for using a fully automatic transplanter tray conveying and recycling device, comprising the following steps: S1: The seedling trays that have been cultivated are manually placed on the tray feeding device. The seedling trays slide down to the drive shaft structure driven by the one-way tray feeding mechanism due to their gravity, and the seedling trays are transported to the reversing track. S2: When the seedling tray is transported to the end of the reversing track, the motor drives the drive shaft eight to reverse and run along the reversing track until the seedling tray is separated from the drive shaft structure. Under its own speed and gravity inertia, the seedling tray connects to the drive shaft six driven by the ratchet and pawl mechanism. S3: When the motor reverses, drive shaft seven can only stop and cannot rotate forward or backward. At this time, subsequent seedling trays can be placed for supply. When the end of the seedling tray opens out of sensor two on one side of the tray track, the alarm sounds and the motor starts to rotate forward, completing the docking of the first end of the seedling tray with the end of the previous seedling tray, forming a continuous working cycle. S4: After the seedling tray moves to the top seedling position, it moves forward by stepping. The ratchet and pawl complete three working cycles. The seedling tray moves forward one row distance. The cam accelerates and rotates under the action of the speed change gear device, pushing the ejector pin to complete the top seedling and complete the separation of the seedling clump from the seedling tray. The empty seedling tray enters the tray exit track and is transported under the drive and linkage of the drive shaft. S5: The seedling trays enter the tray discharge track and the empty trays are stacked and collected in the tray stacking box. Since the tray stacking box and the tray collection position are installed vertically, it is convenient for manual operation.

[0017] The fully automatic transplanter tray conveying and recycling device includes: a frame structure, on which a steel frame (3) is provided, and a front fixed frame (11) and a rear fixed frame (14) are installed on the frame structure. The front fixed frame (11) and the rear fixed frame (14) are respectively provided with a front base fixing bolt (12) and a rear base fixing bolt (13); a pulley 1 (16), a pulley 2 (19), a pulley 3 (21), a pulley 4 (22), a pulley 5 (23), a pulley 7 (101), a pulley 8 (102), a pulley 9 (104), a pulley 10 (108), and a pulley 11 (109) are provided on the frame structure for transmission; a tray feeding device (5) provided on the frame structure for providing a tray conveying channel; a one-way tray feeding mechanism (8) provided on the frame structure for conveying trays; and a one-way output valve (6), a reversing rail (7), a tray discharge rail (15), and a tray stacking device (1) provided on the frame structure.A seedling-lifting device (9) is installed on the frame structure to assist in lifting the seedling clump. The seedling-lifting device 9 has a seedling-lifting structure (110). By setting the frame structure and the steel frame (3) on it, a stable frame foundation is provided for the entire device, so that the various components of the device can be installed and operated in an orderly manner. By setting the front fixed frame (11) and the rear fixed frame (14), as well as the front base fixing bolt (12) and the rear base fixing bolt (13), the device can be stably supported, ensuring the stability of the device during operation and reducing the risk of injury. To minimize the impact of shaking on the operation, pulleys 1 (16), 2 (19), 3 (21), 4 (22), 5 (23), 7 (101), 8 (102), 9 (104), 10 (108), and 11 (109) are installed to provide transmission power to the device, enabling components such as the tray feeding device (5) to operate and realize the function of conveying the seed trays. By setting up the tray feeding device (5), a conveying channel is provided for the seed trays, allowing them to follow a predetermined path. The mobile mechanism provides a foundation for automated transplanting operations. A one-way tray feeding mechanism (8) ensures orderly tray delivery and prevents chaos. A one-way output valve (6) controls the one-way delivery of the trays, preventing reverse movement and ensuring accuracy and stability. A reversing track (7) allows the trays to change direction, meeting the needs of different operational stages and improving flexibility. An output track (15) provides an output channel, enabling trays to be smoothly output after completing their tasks, facilitating subsequent processing. A stacking device (1) stacks the delivered trays, enabling automatic tray recycling and organization, reducing manual labor and improving efficiency. A seedling-lifting device (9) and its internal seedling-lifting structure (110) assist in lifting the seedling clumps, allowing them to detach smoothly from the trays, facilitating subsequent transplanting and improving quality and efficiency.

[0018] The tray exit track (15) is equipped with a drive shaft structure (20), which includes drive shaft one (201), drive shaft two (202), drive shaft three (203), drive shaft four (204), drive shaft five (205), drive shaft six (206), drive shaft seven (207), drive shaft eight (208) and drive shaft nine (209). Drive shaft four (204) is the main power source used for belt drive to link other drive shafts. The tray stacking device (1) includes sensor one (24), sensor two (17) and sensor three (2), electromagnet (103), and tray stacking box. The stacking tray box is fixed to the frame structure by the steel frame (3) and driven by the electromagnet (103). The stacking tray box is used to accommodate the seedling trays (4). The lever structure is used to assist the seedling trays (4) in falling into the stacking tray box under the action of gravity to achieve automatic stacking. By setting the drive shaft structure (20) on the tray discharge track (15), the effect of providing power support for the conveying of the seedling trays on the tray discharge track (15) is achieved. By setting the drive shaft structure (20), the power is reasonably distributed and the operation of each drive shaft is coordinated, so that the entire drive shaft structure (20) can be highly efficient. To ensure efficient and stable operation and balance of power in the delivery of seedling trays on the tray track (15), sensors 1 (24), 2 (17), and 3 (2) are installed in the tray stacking device (1) to monitor various status information during the stacking process in real time, such as the position and quantity of seedling trays (4). This information can be fed back to the control system in a timely manner to enable precise control of the stacking operation and improve the accuracy and reliability of the stacking. Electromagnets (103) are installed in the stacking device (1) to drive the relevant structural actions through electromagnetic control, thereby realizing automated control of the stacking operation. The control system improves the response speed and accuracy. By setting a stacking box in the stacking device (1) and fixing it to the frame structure with a steel frame (3), a stable space is provided for the seedling trays (4), so that the stacking operation can be carried out in an orderly manner within a fixed area, ensuring the neatness and stability of the stacking. By setting a lever structure driven by an electromagnet (103) in the stacking device (1), the seedling trays (4) are assisted to fall into the stacking box under the action of gravity, so that the seedling trays (4) can be stacked automatically, reducing manual intervention, improving stacking efficiency, and further realizing the automation of the stacking process.

[0019] A motor (18) for driving the one-way feeding mechanism (8) is provided on one side of the feeding device (5). A one-way output valve (6) is provided at the junction of the feeding device (5) and the reversing track (7). The motor (18) is located on one side of the reversing track (7). The discharging track (15) is driven by the drive shaft (206) through the drive wheel to achieve intermittent pushing. The power source of the discharging track (15) is the ratchet and pawl mechanism (106) driven by the cylinder (105). The ratchet and pawl mechanism (106) is set on the one-way feeding mechanism 8. The ratchet and pawl mechanism (106) includes an inner pawl wheel (401) rotatably mounted on the tray feeding device 5, a pawl slider (402) for locking the inner pawl wheel (401), a first spring (403) mounted on the pawl slider (402), and a shaft bottom baffle (404) fixed on the first spring (403). Shaft side baffles (405) for stabilizing the pawl slider (402) are provided on both sides of the pawl slider (402). An alarm (1) for prompting tray replenishment is provided on one side of the tray feeding device (5). 13) The stacking device (1) is located at the end of the tray delivery track (15). By setting a motor (18) on one side of the tray delivery device (5) to drive the one-way tray supply mechanism (8), it provides a power source for the one-way tray supply mechanism (8), enabling the one-way tray supply mechanism (8) to operate normally and realize the one-way orderly delivery of the seedling trays, thus ensuring the smoothness of the tray supply process in the entire transplanting operation. By setting the one-way output valve (6) at the junction of the tray delivery device (5) and the reversing track (7), it controls the seedling trays to enter the reversing track from the tray delivery device (5). (7) By placing the motor (18) on one side of the reversing track (7), the motor (18) provides power to the one-way feeding mechanism (8) without interfering with the operation of other components. The drive wheel drives the drive shaft (206) through the discharge track (15) to achieve intermittent pushing, which plays the role of precisely controlling the movement rhythm of the plate on the discharge track (15), so that the plate can be discharged in an orderly manner at a certain time interval. The ratchet and pawl mechanism (106) set up realizes the stable transmission and intermittent output of power of the discharge track (15).

[0020] The tray feeding device (5) is set in an inclined state. The tray feeding device (5) is provided with a seedling tray (4) for holding the seedling clump. The seedling tray (4) slides down and connects to the drive shaft seven (207) by its own weight. By setting the tray feeding device (5) in an inclined state, the weight of the seedling tray (4) and the seedling clump is utilized, so that the seedling tray (4) can slide down naturally along the inclined surface without additional complex power drive, thus achieving the effect of simplifying the power structure and reducing energy consumption. By setting the seedling tray (4) for holding the seedling clump on the tray feeding device (5), the seedling clump is carried and protected in an orderly manner, ensuring that the seedling clump is stable in position during the transportation process and is not easy to fall or be damaged. By allowing the seedling tray (4) to slide down and connect to the drive shaft seven (207) by its own weight, the tray feeding device (5) and the drive shaft structure (20) are connected, so that the seedling tray (4) can smoothly transition from the natural sliding state to the state of being driven by the drive shaft, ensuring the continuity and stability of the entire tray feeding process.

[0021] The reversing track (7) is set in an inclined state. The motor (18) is reversible and used to drive the drive shaft eight (208) to rotate. The seedling tray (4) can slide down the reversing track (7) to the drive shaft six (206) through the combined action of its own kinetic energy and gravitational inertia. This is used to realize intermittent tray feeding. By setting the reversing track (7) in an inclined state, the gravity component is used to form a stable downward guiding force, so that the seedling tray (4) can slide down along a predetermined path after leaving the drive shaft eight (208). By setting the reversible motor (18) to drive the drive shaft eight (208) to rotate, a flexible control method is provided for the feeding of the seedling tray (4). The reversible driving method enables the intermittent tray feeding process to be accurately controlled, and the feeding rhythm of the seedling tray (4) can be flexibly adjusted. Through the combined action of the seedling tray (4)'s own kinetic energy and gravitational inertia, it can slide down the reversing track (7) to the drive shaft six (206).

[0022] The frame structure is provided with a speed-changing gear device (107) for driving the seedling-lifting device (9) at different speeds. The speed-changing gear device (107) includes an adjusting shaft one (301) and a gear two (305). The adjusting shaft one (301) and the gear two (305) are used to drive the cam shaft (111) to extend and retract the ejector pin (306). A connecting rod (303) is installed on the ejector pin (306). A second spring (304) is sleeved on the connecting rod (303) to assist the ejector pin (306) in resetting. By driving the seedling-lifting device (9) at different speeds, the transplanting efficiency can be adjusted. The ingenious combination of gear transmission and cam mechanism converts the rotational motion into the linear reciprocating motion of the ejector pin (306), realizing the control of the seedling-lifting action. A connecting rod (303) is installed on the needle (306) and a second spring (304) is installed on the outer sleeve to assist in the reset. The second spring (304) provides reliable reset power for the needle (306), ensuring that after the seedling-lifting action is completed, the needle (306) can quickly and accurately return to the initial position, preparing for the next seedling-lifting. The spring reset mechanism has the characteristics of fast response speed and high reset accuracy, which can effectively avoid the problem of reset delay or incomplete positioning of the needle (306) due to inertia or friction, and ensure the continuous and stable operation of the seedling-lifting device (9). At the same time, the second spring (304) can also play a buffering role, reducing the impact force on the needle (306) during the seedling-lifting process, extending the service life of the needle (306), and reducing the maintenance cost of the equipment.

[0023] The present invention also provides a method for using a fully automatic transplanter tray conveying and recycling device, comprising the following steps: S1: The seedling tray (4) after seedling cultivation is completed is manually placed on the tray conveying device (5). The seedling tray (4) slides down due to its gravity to the drive shaft structure (20) driven by the one-way tray feeding mechanism (8), which conveys the seedling tray (4) to the reversing track (7); S2: When the seedling tray (4) is transported to the end of the reversing track (7), the motor (18) drives the drive shaft (208) to reverse and run along the reversing track (7) until the seedling tray (4) is separated from the drive shaft structure (20). Under its own speed and gravitational inertia, the seedling tray (4) engages with the drive shaft driven by the ratchet and pawl mechanism (106). S3: When the motor (18) reverses, the drive shaft (207) can only stop and cannot rotate forward or backward. At this time, the subsequent seedling tray (4) can be placed for supply. When the end of the seedling tray (4) opens out of the sensor (17) on one side of the tray track (15), the alarm sounds and the motor (18) starts to rotate forward, completing the docking of the head of the seedling tray (4) with the end of the previous seedling tray (4), forming a continuous working cycle; S4: After the seedling tray (4) moves to the top seedling position, it moves forward by stepping. The ratchet and pawl complete three working cycles. The seedling tray (4) moves forward one row distance. The cam accelerates under the action of the speed change gear device (107), pushing the pin (306) to complete the top seedling, completing the seedling ball and seedling. The tray (4) is separated, and the empty seedling tray (4) enters the tray exit track (15). It is transported under the drive and linkage of the drive shaft (204); S5: The seedling tray (4) enters the tray exit track (15) and completes the stacking and recycling of empty trays in the tray stacking box. Since the position of the tray stacking box and the position of the tray collection are installed vertically, it is convenient for manual operation. By setting the tray feeding device (5) and the drive shaft structure (20) driven by the one-way tray feeding mechanism (8), the effect of automatically transporting the manually placed seedling tray (4) to the reversing track (7) is achieved, realizing the automated starting step of the seedling tray (4) transportation, improving work efficiency and reducing the intensity of manual operation. By setting the motor (18) to drive the drive shaft to reverse, the effect of automatically transporting the manually placed seedling tray (4) to the reversing track (7) is achieved. The drive shaft six (206) driven by the ratchet and pawl mechanism (106) plays a role in ensuring that after the seedling tray (4) is separated from the drive shaft structure (20), it can be smoothly connected to the new drive shaft to continue the conveying, thus ensuring the continuity of the seedling tray (4) conveying process. By setting the drive shaft four (204) to drive and link, the empty seedling tray (4) is conveyed on the tray exit track (15), thus smoothly conveying the empty seedling tray (4) to the stacking tray box, ensuring the smooth flow of the empty seedling tray (4) recycling process. By installing the stacking tray box and the tray collection position vertically, it is convenient for manual operation, thus facilitating the manual collection and sorting of empty seedling trays (4), improving the convenience of manual operation and work efficiency.

The ratchet and pawl mechanism (105) is also provided on the one-way feeding mechanism 8. 6) Includes an inner ratchet wheel (401) rotatably mounted on the tray feeding device 5, a ratchet slider (402) for locking the inner ratchet wheel (401), a first spring (403) mounted on the ratchet slider (402), and a shaft bottom baffle (404) fixed on the first spring (403). Both sides of the ratchet slider (402) are provided with shaft side baffles (405) for stabilizing the ratchet slider (402). One side of the tray feeding device (5) is provided with an alarm (113) for prompting tray replenishment. The tray stacking device (1) is located at the end of the tray exit track (15).

4. The fully automatic transplanter tray conveying and recycling device according to claim 2, characterized in that, The tray feeding device (5) is set in an inclined state. The tray feeding device (5) is provided with a seedling tray (4) for holding the seedling clump. The seedling tray (4) slides down by its own weight and connects to the drive shaft (207).

5. The fully automatic transplanter tray conveying and recycling device according to claim 3, characterized in that, The reversing track (7) is set in an inclined state. The motor (18) can be reversed to drive the drive shaft (208) to rotate. The seedling tray (4) can slide down the reversing track (7) onto the drive shaft (206) through the combined action of its own kinetic energy and gravitational inertia, so as to realize intermittent tray feeding.

6. The fully automatic transplanter tray conveying and recycling device according to claim 1, characterized in that, The frame structure is provided with a speed-changing gear device (107) for driving the seedling device (9) at different speeds. The speed-changing gear device (107) includes an adjusting shaft (301) and a gear (305). The adjusting shaft (301) and the gear (305) are used to drive the camshaft (111) to extend and retract the ejector pin (306). A connecting rod (303) is installed on the ejector pin (306). A second spring (304) is provided on the connecting rod (303) to assist the ejector pin (306) in resetting.

7. The method of using the fully automatic transplanter tray conveying and recycling device according to any one of claims 1-6, characterized in that, Includes the following steps: S1: The seedling tray (4) after seedling cultivation is completed is placed on the tray feeding device (5) by hand. The seedling tray (4) slides down to the drive shaft structure (20) driven by the one-way tray feeding mechanism (8) due to its gravity, and the seedling tray (4) is transported to the reversing track (7). S2: When the seedling tray (4) is transported to the end of the reversing track (7), the motor (18) drives the drive shaft eight (208) to reverse and run along the reversing track (7) until the seedling tray (4) is separated from the drive shaft structure (20). Under its own speed and gravity inertia, the seedling tray (4) connects to the drive shaft six (206) driven by the ratchet and pawl mechanism (106). S3: When the motor (18) reverses, the drive shaft seven (207) can only stop and cannot rotate forward or backward. At this time, the subsequent seedling tray (4) can be placed for supply. When the end of the seedling tray (4) opens out of the sensor two (17) on one side of the tray track (15), the alarm sounds and the motor (18) starts to rotate forward, completing the docking of the head of the seedling tray (4) with the end of the previous seedling tray (4) to form a continuous working cycle. S4: After the seedling tray (4) moves to the top seedling position, it moves forward by stepping. The ratchet and pawl complete three working cycles. The seedling tray (4) moves forward one row distance. The cam accelerates and rotates under the action of the speed change gear device (107), pushing the ejector pin (306) to complete the top seedling and complete the separation of the seedling ball from the seedling tray (4). The empty seedling tray (4) enters the tray exit track (15) and is transported under the drive and linkage of the drive shaft four (204). S5: The seedling tray (4) enters the tray exit track (15) and completes the stacking and recycling of empty trays in the tray stacking box. Since the tray stacking box and the tray collection position are installed vertically, it is convenient for manual operation.
