Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a novel rice transplanter. Background Technology

[0002] A rice transplanter is an agricultural machine used to plant rice seedlings in paddy fields. It is mainly used in rice planting and replaces manual transplanting by using machinery, which helps to improve the efficiency of rice transplanting and saves a lot of manpower.

[0003] Currently, most rice transplanters are ride-on transplanters. These transplanters use diesel engines as their power source and transmit power to various transplanting actuators, such as the planting and transplanting components and the seedling tray assembly, through a transmission mechanism to achieve efficient transplanting operations. For example, a ride-on transplanter disclosed in Chinese patent CN211430033U uses an engine to drive a gearbox, which in turn drives the transplanting mechanism. The power transmission shaft drives the seedling assembly, and the seedling tray control mechanism controls the seedling tray frame. Each actuator uses a separate transmission mechanism, resulting in a large overall weight. During transplanting, the wheels sink significantly, making it unusable in many environments. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and problems of existing technologies, such as large weight and limited applicability, and to provide a new type of rice transplanter that is smaller in weight and has a wider range of applications.

[0005] To achieve the above objectives, the technical solution of this utility model is: a novel rice transplanter, comprising a chassis, a seed box, and a handle. The chassis is horizontally arranged, and two connecting blocks are symmetrically arranged on the upper side of the chassis. A rotating rod is rotatably connected between the two connecting blocks. A transmission mechanism for driving the rotating rod to swing back and forth is connected to the outer circumference of the rotating rod. The input end of the transmission mechanism is connected to a power device. Multiple planting arms are axially spaced connected to the outer circumference of the rotating rod, and a clamping device for holding seedlings is connected to the upper side of each planting arm. The seedling fork has a support plate connected to the upper side of the two connecting blocks. The seedling box is slidably connected to the upper side of the support plate along the length direction of the support plate. The seedling box contains seedlings. The bottom of the seedling box has a seedling feeding port corresponding to multiple seedling arms. The rear side of the seedling box is connected to a drive mechanism for driving the seedling box to slide back and forth. The input end of the drive mechanism is connected to the rotating rod. The upper side of the chassis has a seedling insertion port corresponding to multiple seedling forks. The handle is vertically connected to the upper side of the chassis.

[0006] The transmission mechanism includes a driving wheel, a driven wheel, a belt, a first connecting rod, a second connecting rod, and a third connecting rod. The driving wheel is connected to a power device. The belt is wound around the outer circumferential surfaces of the driving wheel and the driven wheel. One end of the first connecting rod is connected to the center of one end face of the driven wheel. One end of the second connecting rod is hinged to the other end of the first connecting rod. One end of the third connecting rod is hinged to the other end of the second connecting rod. The other end of the third connecting rod is connected to the outer circumferential surface of the rotating rod.

[0007] The seedling box includes a seedling feeding plate, which is arranged at an angle and connected to baffles on its left and right sides. A base plate is slidably connected to the lower side of the seedling feeding plate, and multiple seedling feeding ports are opened on the base plate. A retaining plate is provided on the upper side of the base plate, which is connected to the lower side of the seedling feeding plate and located between two baffles. A retaining groove is provided on the retaining plate, and a seedling picking fork is located in the retaining groove and arranged relative to the seedling feeding ports. A first sliding plate is provided on the rear side of the seedling feeding plate. The first sliding plate and a support plate are both L-shaped. The base plate is connected to the horizontal part of the support plate. The vertical part of the first sliding plate is located between the vertical parts of the seedling feeding plate and the support plate. A limiting plate is connected to the horizontal part of the first sliding plate. The limiting plate fits against the horizontal part of the support plate. A connecting shaft is connected between the limiting plate and the first sliding plate. A first roller is rotatably connected to the outer circumference of the connecting shaft. The first roller is rotatably connected to the upper side of the horizontal part of the support plate.

[0008] A second sliding plate is provided on the rear side of the seedling feeding plate. The second sliding plate is L-shaped. The vertical part of the second sliding plate is connected to the rear side of the seedling feeding plate. A support column is vertically connected to the upper side of the chassis. The handrail is inclinedly connected to the rear side of the support column. A second roller is rotatably connected to the upper end face of the support column. The second roller is rotatably connected to the lower side of the horizontal part of the second sliding plate.

[0009] Both baffles are connected to connecting plates at intervals on their upper sides. Multiple limiting grooves are provided on the connecting plates at intervals along the length direction. Limiting rods are connected in the limiting grooves. The distance between the limiting rods and the seedling delivery plate matches the length of the seedlings.

[0010] The rear side of the seedling delivery plate is connected to a bracket for storing the limiting rod.

[0011] The upper side of the seedling-picking fork has a notch for accommodating seedlings. The middle part of the seedling-picking fork is hinged to the upper end of the planting arm. The lower side of the seedling-picking fork is connected to two clamps, which are slidably connected to the left and right sides of the planting arm.

[0012] Multiple push plates are provided between the rotating rod and the rice planting port. Each push plate is arranged in a corresponding manner with a multiple rice seedling picking fork.

[0014] The two connecting blocks are hinged to the rear sides with intercepting rods, and a thin wire connects the two intercepting rods.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses a novel rice transplanter. By incorporating a transmission mechanism, the transplanting arm and the seed-picking fork can swing back and forth to achieve transplanting. Simultaneously, the transmission mechanism drives a drive mechanism, causing the seedling box to move back and forth. The transmission mechanism is connected to a power unit. Thus, only one transmission mechanism is needed to achieve repeated movement of the seedling box and repeated seed-picking and transplanting by the seed-picking fork. All actuators share a single transmission mechanism. Compared to existing technologies, the transmission mechanism is relatively lightweight. Furthermore, by adding a handle, the chassis can be moved in the field by manual gripping, facilitating control of the transplanter's movement and preventing it from sinking into the field. This makes it suitable for various scenarios. Therefore, this utility model is lightweight and has a wide range of applications.

[0017] 2. In this novel rice transplanter, the transmission mechanism uses multiple connecting rods to drive the rotating rod in reciprocating motion. The motion trajectory is regular. Driven by the transmission mechanism, the seedling moves to the transplanting opening and is inserted into the field. Then, the fork returns to the starting position. Through periodic movement, the fork can repeat the transplanting process. By setting a push plate, when the fork contacts the push plate, the push plate is positioned in a notch. As the fork continues to move, the area occupied by the push plate in the notch increases, thus squeezing the seedling out of the notch. This avoids excessive clamping force from the fork pulling the planted seedling and causing it to tilt when inserted into the field. Therefore, this invention has a stable and highly reliable working process.

[0018] 3. In this novel rice transplanter, a clamping plate is incorporated to prevent seedlings from falling over due to insufficient support at the base plate when the seedlings are positioned on it, thus avoiding the seedlings tipping over during transplanting. The first and second sliding plates allow the seedling box to slide back and forth between the support column and the support plate. A limiting plate restricts the forward and backward movement of the first sliding plate, preventing the seedling box from veering off course during movement. Limiting grooves and rods accommodate seedlings of varying heights, improving flexibility and reducing the probability of missed seedlings. A support frame allows the limiting rod to be stored after transplanting for easy access. Therefore, this invention offers stable operation, good transplanting stability, wide applicability, and ease of use.

[0019] 4. In this novel rice transplanter, a pressure rod is incorporated. Driven by a transmission mechanism, the rotating rod can swing back and forth, periodically pressing the swing arm. When the swing arm presses down, it simultaneously moves the support rod and rocker arm downwards. This downward movement of the rocker arm drives a one-way gear, causing the chain to rotate and the push block to move to the right. At this time, the tension spring is stretched. When the pressure rod is not pressing the swing arm, the support rod and rocker arm move upwards under tension, driving the one-way gear to rotate. The chain does not rotate at this time. The one-way gear enables periodic movement of the seedling box, resulting in a stable structure. Since the pusher block is positioned between the first and second limiting blocks, its movement abuts against the second limiting block and moves the seedling box to the right. When the pusher block moves below the chain, it contacts the first limiting block and moves the seedling box to the left, thus achieving reciprocating movement of the seedling box with stable motion. By incorporating an intercepting rod and a thin line, the line can limit the movement of the seedling when the seedling-grasping fork grips the seedling downwards, preventing the seedling from tipping over during rotation. Therefore, this invention offers stable operation and good transplanting stability. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1:

[0033] See Figures 1 to 10 A novel rice transplanter includes a chassis 1, a seedling box 2, and a handle 10. The chassis 1 is horizontally arranged, and two connecting blocks 5 are symmetrically arranged on the upper side of the chassis 1. A rotating rod 6 is rotatably connected between the two connecting blocks 5. A transmission mechanism 3 for driving the rotating rod 6 to swing back and forth is connected to the outer circumference of the rotating rod 6. The input end of the transmission mechanism 3 is connected to a power device. Multiple planting arms 7 are axially spaced connected to the outer circumference of the rotating rod 6. A seedling picking fork 8 for clamping seedlings is connected to the upper side of the planting arm 7. The upper part of the two connecting blocks 5... A support plate 9 is connected to the side. The seedling box 2 is slidably connected to the upper side of the support plate 9 along the length direction of the support plate 9. Seedlings are stored in the seedling box 2. The bottom of the seedling box 2 is provided with a seedling feeding port 215 corresponding to a plurality of seedling arms 7. The rear side of the seedling box 2 is connected to a drive mechanism 4 for driving the seedling box 2 to slide back and forth. The input end of the drive mechanism 4 is connected to the rotating rod 6. The upper side of the chassis 1 is provided with a seedling insertion port 11 corresponding to a plurality of seedling picking forks 8. The handle 10 is vertically connected to the upper side of the chassis 1.

[0034] The transmission mechanism 3 includes a drive wheel 31, a driven wheel 32, a belt 33, a first connecting rod 34, a second connecting rod 35, and a third connecting rod 36. The drive wheel 31 is connected to the power equipment. The belt 33 is wound around the outer circumferential surfaces of the drive wheel 31 and the driven wheel 32. One end of the first connecting rod 34 is connected to the center of one end face of the driven wheel 32. One end of the second connecting rod 35 is hinged to the other end of the first connecting rod 34. One end of the third connecting rod 36 is hinged to the other end of the second connecting rod 35. The other end of the third connecting rod 36 is connected to the outer circumferential surface of the rotating rod 6.

[0035] In this embodiment, the power equipment can be an electric motor, the output shaft of which is connected to the drive wheel 31. At the same time, rotating wheels can be connected to the left and right sides of the chassis 1.

[0036] When in use, the motor is started, and the chassis 1 is moved by the handle 10. The chassis 1 moves on the field under the drive of the rotating wheel. At the same time, the drive wheel 31 rotates, which drives the driven wheel 32 to rotate. The driven wheel 32 rotates, which drives the first connecting rod 34 to rotate in a circular direction. The second connecting rod 35 and the third connecting rod 36 reciprocate, causing the rotating rod 6 to swing back and forth. The seedling picker 8 moves to the seedling delivery port 215 to clamp the seedling under the drive of the rotating rod 6, and continues to rotate to the transplanting port 11 to insert the seedling into the field. Then the seedling picker 8 returns to the starting position. Through periodic movement, the seedling picker 8 can repeat the transplanting.

[0037] Example 2:

[0038] The basic content is the same as in Example 1, except that:

[0039] See Figures 2 to 6 The seedling box 2 includes a seedling feeding plate 21, which is arranged at an angle and connected to baffles 22 on both sides. A base plate 23 is slidably connected to the lower side of the seedling feeding plate 21. The base plate 23 has multiple seedling feeding openings 215. A retaining plate 24 is provided on the upper side of the base plate 23. The retaining plate 24 is connected to the lower side of the seedling feeding plate 21 and located between two baffles 22. A retaining groove 25 is provided on the retaining plate 24. The seedling picking fork 8 is located in the retaining groove 25 and is positioned relative to the seedling feeding plate. The seedling feeding plate 21 is arranged in an L-shape, with a first sliding plate 26 located on its rear side. Both the first sliding plate 26 and the support plate 9 are L-shaped. The bottom plate 23 is connected to the horizontal portion of the support plate 9. The vertical portion of the first sliding plate 26 is located between the vertical portions of the seedling feeding plate 21 and the support plate 9. A limiting plate 27 is connected to the horizontal portion of the first sliding plate 26. The limiting plate 27 is fitted against the horizontal portion of the support plate 9. A connecting shaft 28 connects the limiting plate 27 and the first sliding plate 26. A first roller 29 is rotatably connected to the outer circumferential surface of the connecting shaft 28. The first roller 29 is rotatably connected to the upper side of the horizontal part of the support plate 9. A second sliding plate 214 is provided on the rear side of the seedling feeding plate 21. The second sliding plate 214 is L-shaped, and its vertical part is connected to the rear side of the seedling feeding plate 21. A support column 13 is vertically connected to the upper side of the chassis 1. The handle 10 is inclinedly connected to the rear side of the support column 13. A second roller is rotatably connected to the upper end face of the support column 13. The second roller 14 is rotatably connected to the lower side of the horizontal part of the second slide plate 214. The upper sides of the two baffles 22 are connected with connecting plates 210 at intervals. Multiple limiting grooves 211 are spaced apart along the length direction on the connecting plates 210. Limiting rods 212 are connected in the limiting grooves 211. The distance between the limiting rods 212 and the seedling feeding plate 21 matches the length of the seedlings. The rear side of the seedling feeding plate 21 is connected with a bracket 213 for storing the limiting rods 212.

[0040] In this embodiment, the seedlings are first placed in the seedling delivery plate 21. By adjusting the distance between the limiting plate 27 and the seedling delivery plate 21, the seedlings can be prevented from collapsing. The seedling head at the bottom is placed on the clamping plate 24, and the root is placed in the clamping groove 25 and placed on the base plate 23. The seedling delivery plate 21 and the clamping plate 24 slide back and forth on the support plate 9 and the support column 13 under the action of the driving mechanism 4. When sliding, the seedlings are pushed to move so that the roots of the seedlings fall into the seedling delivery port 215 and are taken out by the seedling picking fork 8.

[0041] Example 3:

[0042] The basic content is the same as Example 2, except that:

[0043] See Figure 7 and Figure 8 The upper side of the seedling fork 8 is provided with a notch 15 for accommodating seedlings. The middle part of the seedling fork 8 is hinged to the upper end of the planting arm 7. The lower side of the seedling fork 8 is connected to two clamping plates 16. The two clamping plates 16 are slidably connected to the left and right sides of the planting arm 7. The rear side of the two connecting blocks 5 is hinged to an intercepting rod 18. A thin line 19 is connected between the two intercepting rods 18. Multiple push plates 17 are provided between the rotating rod 6 and the planting port 11. The multiple push plates 17 are arranged one-to-one with the multiple seedling forks 8. The multiple push plates 17 are all connected to the upper side of the chassis 1. The upper side of the push plates 17 is arranged at an angle.

[0044] In this embodiment, the initial position of the seedling picker 8 is in the slot 25, and the seedling picker 8 remains vertical on the planting arm 7. When the rotating rod 6 rotates, the planting arm 7 drives the seedling picker 8 to rotate clockwise, and the upper side of the seedling picker 8 moves into the seedling feeding port 215. Since there are seedlings stored in the seedling feeding port 215, the notch 15 of the seedling picker 8 clamps the seedlings. The seedling picker 8 continues to rotate. Under the action of the weight of the seedlings and the limiting action of the thin line 19, the seedling picker 8 rotates on the planting arm 7, and at the same time... The seedlings remain upright. When the push plate 17 contacts the notch 15, the area occupied by the push plate 17 in the notch 15 increases, thus squeezing the seedlings out of the notch 15. At this time, the seedlings are in contact with the field when the seedling fork 8 is inserted into the planting hole 11. The rotating rod 6 continues to rotate, and the planting arm 7 drives the seedling fork 8 to rotate counterclockwise. Due to its own weight, when the planting arm 7 rotates to a vertical position, the seedling fork 8 also rotates to a vertical position and the subsequent transplanting work is carried out.

[0045] Example 4:

[0046] The basic content is the same as in Example 1, except that:

[0047] See Figure 9 and Figure 10The drive mechanism 4 includes a base 41, a rocker arm 410, a swing arm 412, and a support rod 411. The base 41 is connected to the rear side of the seedling box 2. A first rotating shaft 42 and a second rotating shaft 43 are rotatably connected to the base 41. One end of the first rotating shaft 42 is connected to a drive sprocket 44, and one end of the second rotating shaft 43 is connected to a driven sprocket 45. A chain 414 is meshed with the outer circumferences of the drive sprocket 44 and the driven sprocket 45. A push block 46 is connected to the outer side of the chain 414. A first limiting block 47 and a second limiting block 48 are connected to the rear side of the seedling box 2. The push block 46 is located between the first limiting block 47 and the second limiting block 48. The lower side of the limiting block 47 is located below the base 41. The other end of the first rotating shaft 42 passes through the base 41 and is connected to a one-way gear 49. One end of the rocker arm 410 is located in the tooth groove of the one-way gear 49. The other end of the rocker arm 410 is connected to the upper end of the support rod 411. The lower end of the support rod 411 is connected to a swing arm 412. One end of the swing arm 412 is hinged to the upper side of the chassis 1. The outer circumferential surface of the rotating rod 6 is connected to a pressure rod 12. The swing arm 412 is arranged relative to the pressure rod 12. One end of the swing arm 412 is located below one end of the pressure rod 12. A tension spring 413 is connected between the swing arm 412 and the base 41.

[0048] In this embodiment, the specific structure and principle of the one-way gear 49 can be referred to a one-way gear disclosed in Chinese Patent CN204253790U.

[0049] In use, the pressure rod 12 rotates under the drive of the rotating rod 6 and contacts the swing rod 412, causing the swing rod 412 to rotate counterclockwise. At the same time, the support rod 411 and the rocker arm 410 move downwards synchronously, the tension spring 413 is stretched, and the one-way gear 49 rotates clockwise under the drive of the rocker arm 410, causing the first rotating shaft 42 and the drive sprocket 44 to rotate clockwise. The drive sprocket 44 drives the chain 414 to rotate clockwise, causing the push block 46 to move to the right a certain distance. The push block 46 contacts the second limiting block 48, causing the second limiting block 48 and the seedling box 2 to move to the right a certain distance. Then, the pressure rod 12 rotates in the opposite direction and moves away from the swing rod 412 under the drive of the rotating rod 6. The tension spring 413 resets and drives the support rod 411 and the rocker arm 410 to move upward synchronously, causing the one-way gear 49 to rotate counterclockwise. At this time, the first rotating shaft 42 does not rotate. After the rotating rod 6 rotates multiple times, the push block 46 moves to the right periodically. When the push block 46 moves from above the chain 414 to below the chain 414, the push block 46 moves to the left and contacts the first limit block 47, driving the seedling box 2 to move to the left, and finally realizing the reciprocating left and right movement of the seedling box 2.
