Description

Technical Field

[0001] This utility model relates to a device, particularly a planting device, and especially a high-efficiency rice seedling planting device. Background Technology

[0002] As one of the world's major food crops, rice cultivation efficiency and quality directly impact food security and agricultural economic benefits. Traditional rice planting relies mainly on manual transplanting or semi-mechanized equipment, which suffers from high labor intensity, low efficiency, and uneven plant spacing. Especially in hilly areas or small-scale farmland, large rice transplanters are difficult to popularize due to their poor terrain adaptability and high cost, resulting in farmers still relying primarily on manual transplanting. Statistics show that the average daily workload of manual rice transplanting is less than 0.5 mu per person, and prolonged bending over can easily lead to lumbar spine diseases, exacerbating the shortage of agricultural labor.

[0003] In recent years, although existing semi-automatic rice transplanters have improved efficiency, they still have obvious shortcomings in practical applications:

[0004] 1) The mechanical structure is complex and can easily damage the root system when picking up seedlings, leading to a prolonged seedling recovery period;

[0005] 2) Poor uniformity in planting depth affects rice tillering and lodging resistance;

[0006] 3) Insufficient automation, requiring frequent adjustments to plant spacing parameters, resulting in a high operational threshold.

[0007] To address the aforementioned technical bottlenecks, there is an urgent need to develop a compact and highly adaptable high-efficiency rice seedling planting device. Through technological innovations such as optimizing the seedling clamping mechanism and reducing energy consumption, this device can achieve precise, lightweight, and environmentally friendly rice planting, providing a new solution for mechanized rice cultivation.

[0008] Chinese utility model patent CN201178575 Y discloses a rice transplanter, which includes a power walking mechanism, a power transmission mechanism fixedly installed on the power walking mechanism, a support mechanism, and a planting mechanism and a seedling delivery mechanism installed on the support mechanism. The support mechanism, planting mechanism, and seedling delivery mechanism are detachably installed on the power transmission mechanism. This rice transplanter is a semi-automatic transplanter with insufficient automation, poor consistency in planting depth, and affects rice tillering and lodging resistance. Utility Model Content

[0009] This invention aims to overcome the shortcomings of the prior art by providing a high-efficiency rice seedling planting device that efficiently plants rice seedlings in paddy fields, thus meeting the need for rice seedlings to be planted quickly in paddy fields.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: This high-efficiency rice seedling planting device includes a support plate, a vertical frame fixed to the side end of the support plate and perpendicular to the support plate, an inclined frame fixed to the vertical frame at a 65° angle to the support plate, a horizontal shaft rotatably connected to the bottom of the outer end face of the inclined frame, a set of seedling pulling parts evenly distributed axially on the horizontal shaft, and a set of transplanting parts matching the number and position of the seedling pulling parts installed on the support plate; the seedling pulling parts include a disc fixed to the inclined frame, the disc having an inner contour of a track, a bushing fixed to the side end of the disc on the horizontal shaft, a vertical rod radially fixed to the bushing, an insertion hole on the vertical rod, an insertion rod inserted into the insertion hole, an upper pressure plate fixed to the top surface of the insertion rod, a lower pressure plate cooperating with the upper pressure plate fixed to the top of the vertical rod, a longitudinal guide hole communicating with the insertion hole on the vertical rod, a horizontal rod passing through the longitudinal guide hole and cooperating with the inner contour of the track fixed to the insertion rod, and a compression spring installed between the bottom surface of the insertion rod and the bottom surface of the insertion hole. The rice transplanter includes a first support fixed to a support plate, a rotating shaft rotatably connected to the first support, a rotating wheel and a first chain gear fixed to the rotating shaft, a second support fixed to the support plate at the side end of the first support, a first connecting rod hinged to the second support, a second connecting rod hinged to the outer end of the first connecting rod, the second connecting rod being eccentrically hinged to the first chain gear, a rice transplanter fixed to the outer end of the second connecting rod at a 100° angle to the second connecting rod, and a rice transplanter slot at the head end of the rice transplanter; a set of seedling horizontal stacking slots, each matching the number and position of the seedling pulling components, are installed on the inclined frame; a tray is provided below the bottom of the seedling horizontal stacking slots, and an opening for the upper pressure plate to pass through the tray and the inclined frame; a set of rice transplanter slots are provided on the support plate for the passage of each rice transplanter; a drive mechanism is installed on the support plate to drive the seedling pulling components and the rice transplanter to operate in coordination; and an upturned plate matching the position of each rice transplanter slot is provided at the front end of the support plate.The function of the seedling-pulling component here is to pull out the rice seedlings located in the horizontal stacking groove; the function of the transplanting component here is to carry the rice seedlings located on the seedling-pulling component out and insert them into the paddy field; the function of the horizontal stacking groove is to push the rice seedlings together horizontally, thereby facilitating the quick and easy planting operation; the function of the drive mechanism here is to coordinate the coordinated operation between the seedling-pulling component and the transplanting components, thereby quickly pulling out the rice seedlings located in the horizontal stacking groove and inserting them into the paddy field; the working principle of the seedling-pulling component is: horizontal axis The rotation causes the vertical poles to rotate, and the horizontal bars on the vertical poles are moved along the inner contour of the trajectory. This causes the upper pressure plate to continuously adjust its clamping position with the lower pressure plate according to the rotation position of the vertical poles. When the vertical poles rotate to the bottom of the seedling stacking trough, the distance between the upper and lower pressure plates is relatively large, and two to three rice seedlings are inserted and pulled out from the seedling stacking trough. After being pulled out, the rice seedlings are relatively clamped. Then, after rotating a short distance, the upper and lower pressure plates are released again, allowing the rapidly moving transplanting pole to push the rice seedlings out of the transplanting trough. The upper and lower pressure plates are positioned between the upper and lower plates and then inserted into the paddy field. The working principle of the transplanter is as follows: the first chain gear rotates, causing the second connecting rod to swing. As the second connecting rod swings, it simultaneously drives the transplanting rod and the transplanting groove to make a horizontal, arc-shaped outward push, and then insert downwards, thus inserting the rice seedlings located on the seedling-pulling device into the paddy field. The function of the upper tilting plate is to prevent the head of the support plate from getting stuck in the paddy field when it moves across the paddy field, serving as a guide and preventing insertion into the paddy field. The 65° angle between the inclined frame and the support plate is to ensure the seedlings are horizontally... The rice seedlings are tilted towards the stacking trough, allowing them to move automatically downwards under gravity. After two or three seedlings are removed from the bottom of the trough, the remaining seedlings automatically move down to replenish the bottom. The 100° angle between the second connecting rod and the transplanting rod allows the transplanting rod to move laterally in an arc and insert downwards when the second connecting rod swings. The compression spring is a return spring, and the horizontal bar can adjust its position according to the shape of the trajectory.

[0011] Further improvements include a drive shaft rotatably connected to a support plate, a set of second chain gears whose positions and numbers match those of each first chain gear, a first chain installed between each second chain gear and each first chain gear, a third chain gear fixed on any rotating shaft, a fourth chain gear corresponding to the position of the third chain gear fixed on a horizontal shaft, a second chain installed between the fourth chain gear and the third chain gear, a first synchronous pulley fixed to the side end of the drive shaft, a first drive motor fixed on the support plate, a second synchronous pulley fixed on the rotating shaft of the first drive motor, and a synchronous belt installed between the second synchronous pulley and the first synchronous pulley. The function of the drive mechanism here is to enable the seedling pulling component and each transplanting component to operate in coordination, thereby completing the seedling pulling and transplanting unloading operations. The function of the drive shaft, second chain gear, third chain gear, fourth chain gear, second chain, first synchronous pulley, first drive motor, second synchronous pulley, and synchronous belt is that, with just one drive motor, the second synchronous pulley drives the synchronous belt to rotate, which in turn drives the first synchronous pulley to rotate, thereby driving the drive shaft to rotate. The sixth chain gears on the drive shaft will also rotate synchronously, thereby driving the first chain gears to rotate, which in turn drives the second connecting rod to swing continuously. This causes the transplanting slot on the transplanting rod to push out the seedlings held between the upper and lower pressure plates and insert them into the field. Simultaneously, through the third chain gear, and based on the force transmitted by the second chain, the fourth chain gear rotates synchronously. Thus, when the drive shaft rotates, the horizontal shaft is also driven to rotate synchronously, thereby enabling the seedling pulling component and the transplanting component to operate synchronously and in coordination, thereby first pulling out the seedlings located in the horizontal stacking slot and then inserting them into the paddy field.

[0012] Further improvements include a pair of opposing floats fixed to the bottom surface of the support plate, a pair of symmetrical openings along the center of the support plate, a third support installed on both sides of each opening, a drive shaft installed between the two third supports, a pull wheel fixed on each drive shaft located at the opening and embedded in the soil layer, a fifth chain gear fixed on each drive shaft, a pair of sixth chain gears fixed on the drive shaft matching the positions of the two fifth chain gears, and a fourth chain installed between the sixth chain gears and the fifth chain gears. The purpose of the float here is to allow the device to float on the paddy field and avoid sinking into the field and becoming immobile. The purpose of the opening, the third support, the drive shaft, the actuating wheel, the fifth chain gear, the sixth chain gear, and the fourth chain is to allow the actuating wheel to embed itself into the soil layer. Then, when the drive shaft rotates, the fourth chain drives the fifth chain gear to rotate, thereby driving the actuating wheel to rotate. This allows the rotation speed of the actuating wheel to be matched with the rotation speed of the drive shaft, thus coordinating the movement of the seedling inserter, the transplanting inserter, and the actuating wheel for transplanting.

[0013] Further improvements include a seedling tray fixed to the top of the slanted frame. The purpose of this tray is to hold a large number of seedlings. When the seedlings in the horizontally stacked seedling trough are nearly planted, seedlings can be easily and promptly retrieved from the tray to replenish the trough for continued automatic planting. This avoids the inefficiency caused by manually retrieving seedlings from the seedling cultivation field.

[0014] Further improvements include the addition of a seat fixed to the support plate. The purpose of this seat is to allow the operator to sit comfortably, reducing labor intensity and making automatic rice planting more comfortable.

[0015] Further improvements include a cover fixed to the support plate to enclose the rice transplanter; wheel frames slidably connected to both sides of the cover; a pair of opposing wheels mounted on the wheel frames; a second drive motor driving the wheels to rotate on both wheel frames; first electric cylinders that move the wheel frames up and down on both sides of the cover; a rear wheel support frame hinged to the support plate; a rear support wheel mounted on the rear wheel support frame; a second electric cylinder mounted between the support plate and the rear wheel support frame; the bottom end of the second electric cylinder hinged to the support plate; and the piston rod end of the second electric cylinder hinged to the rear wheel support frame. A first switch controlling the operation of the first drive motor is mounted on the seedling placement tray, and a second switch controlling the operation of both the first and second electric cylinders is mounted on the seedling placement tray. A pair of opposing handles are mounted on the side of the seat, and a rotary speed control switch controlling the operation of the second drive motor is mounted on either handle. A rechargeable battery connected to the rotary speed control switch, the first switch, the second switch, the first drive motor, the second drive motor, the first electric cylinder, and the second electric cylinder is installed under the seat. The purpose of the casing is to protect the rice transplanter. The wheel frame, wheels, second drive motor, and first electric cylinder are designed to allow the device to be moved independently on the road to other paddy fields or back to its storage location. The first electric cylinder lowers the wheel frame, lifting the device, and the second drive motor then moves the wheels. The rear wheel support frame, rear support wheel, and second electric cylinder allow the second electric cylinder to adjust the angle of the rear wheel support frame, aligning the rear support wheel with the wheel at the same horizontal level. This ensures smoother movement of the device on the road and prevents center of gravity shift. The device experiences a backward tilting phenomenon. The first switch controls the operation of the first drive motor. The second switch controls the operation of the first and second electric cylinders. The handle allows for easy control of the device's direction of movement when it needs to be moved to another location. The rotary speed control switch allows for convenient control of the second drive motor's speed, thus facilitating the device's relocation speed. The rechargeable battery provides power to the first and second drive motors, the first and second electric cylinders, and facilitates planting and moving operations. A lithium-ion rechargeable battery is used.

[0016] The beneficial effects of this utility model are:

[0017] 1) The seedling puller can pull out rice seedlings located in the horizontal stacking trough;

[0018] 2) The rice seedlings on the seedling pulling device can be pulled out and inserted into the paddy field through the seedling transplanting device; the rice seedlings can be stacked horizontally through the seedling horizontal stacking trough, which makes it convenient and quick to plant rice seedlings.

[0019] 3) The drive mechanism can coordinate the operation of the seedling pulling component and the various transplanting components, thereby quickly pulling out the seedlings located in the horizontal stacking trough and inserting them into the paddy field.

[0020] 4) The float allows the device to float on the paddy field, preventing it from sinking into the field and becoming immobile;

[0021] 5) The wheel frame, wheels, second drive motor, and first electric cylinder enable the device to be moved on its own on the road to other paddy fields or back to its storage location. The first electric cylinder can drive the wheel frame to move down and lift the device, and then the second drive motor can drive the wheels to move, thus moving the device as a whole. The rear wheel support frame, rear support wheel, and second electric cylinder enable the second electric cylinder to drive the rear wheel support frame to change its angle, so that the lower position of the rear support wheel is on the same horizontal line as the wheel. This makes the device more stable when moving on the road and prevents the center of gravity from shifting and causing it to tip over. Attached Figure Description

[0041] The working principle of this utility model is as follows: First, rice seedlings 31 are stacked in the seedling placement tray 16. Then, the rice seedlings 31 are stacked horizontally in the seedling horizontal stacking placement groove 7. Subsequently, the first switch 28 is pressed, which immediately starts the first drive motor 8-7, thereby driving the second synchronous pulley 8-8 to rotate. The rotation of the second synchronous pulley 8-8 will drive the synchronous belt 8-9 to rotate, which in turn drives the first synchronous pulley 8-6 to rotate, and then drives the entire drive shaft 8-1 to rotate. When the entire drive shaft 8-1 rotates, it will be synchronous. This drives the second chain gears 8-2 to rotate, and the sixth chain gear 14 to rotate, thereby synchronously driving the first chain gears 6-3, the horizontal shaft 4, and the actuating wheel 12 to rotate. The actuating wheel 12 then moves the entire device rhythmically. The horizontal shaft 4 rotates, thereby driving the vertical rods 5-3 to rotate. Simultaneously, the horizontal rods 5-5 on the vertical rods 5-3 are driven along the inner contour 5-1a of the trajectory, causing the upper pressure plate 5-4a to continuously adjust its clamping position with the lower pressure plate 5-3b according to the rotational position of the vertical rods 5-3. When the vertical pole 5-3 rotates to the bottom of the seedling horizontal stacking trough 7, the gap between the upper pressure plate 5-4a and the lower pressure plate 5-3b is relatively large, and two to three rice seedlings are inserted (the upper pressure plate 5-4a and the lower pressure plate 5-3b work together to clamp the rice seedlings) and are pulled out horizontally from the bottom opening of the seedling horizontal stacking trough 7. After being pulled out, the rice seedlings 31 are relatively clamped. Then, after rotating a short distance, the upper pressure plate 5-4a and the lower pressure plate 5-3b are released again. At this time, the transplanting pole 6-7 moves out quickly and passes through the transplanting trough. Rice seedlings 31 are inserted into the groove 6-7a and brought out from between the upper pressure plate 5-4a and the lower pressure plate 5-3b and quickly inserted into the paddy field, thus completing the transplanting process of one row of rice seedlings 31 at a time. By repeating the above operation, the rice seedlings 31 can be planted at equal intervals. The process is highly automated, the rice seedlings 31 are inserted appropriately, which is conducive to growth. Moreover, when there are not enough rice seedlings 31 in the horizontal stacking groove 7, they can be supplemented by rice seedlings 31 located at the seedling placement tray 16. This method is worth promoting and applying.
