Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to the field of transplanting sweet potato seedlings, and specifically refers to a fully automatic sweet potato seedling horizontal transplanter and a transplanting method. Background Art

[0002] Sweet potato is a nutritious, widely used, high-yield and stable food crop. my country ranks first in the world in terms of sweet potato planting area and total output. At present, the main sweet potato planting methods include oblique planting, horizontal planting, straight planting, boat-bottom planting, hook-shaped planting, etc. Among them, oblique planting and horizontal planting are the most in line with the agronomic requirements of sweet potato planting. However, due to the lack of relevant transplanting machinery, sweet potato planting mainly relies on manual planting, which is labor-intensive and seriously restricts the development of the sweet potato industry. Therefore, achieving mechanized transplanting that meets the agronomic requirements of sweet potato planting has become an urgent problem to be solved in sweet potato planting. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a fully automatic sweet potato seedling horizontal transplanter and a transplanting method, thereby realizing the mechanized transplanting of the sweet potato seedlings.

[0004] The present invention is achieved through the following technical scheme, which provides a fully automatic sweet potato seedling horizontal transplanter, including a frame with ground wheels, and a rotary tillage device, a ridging device and a seedling delivery device installed on the frame from front to back, the seedling drop point of the seedling delivery device is adapted to the ridging device, a seedling separation device is provided above the seedling delivery device, and the seedling drop point of the seedling separation device is adapted to the seedling delivery device.

[0005] When this solution is in use, the frame is driven to move by the traction equipment, the land is reclaimed and loosened by the rotary tillage device, and the loosened soil is ridged and shaped by the ridging device to ensure the accuracy of the seedling placement of the seedling delivery device, the separated seedlings are delivered to the seedling delivery device by the seedling separation device, and the seedlings are delivered to the shaped field ridges by the seedling delivery device, thereby realizing the mechanized transplanting of the seedlings.

[0006] As an optimization, the seedling separation device includes a roller V, a first seedling belt and a second seedling belt overlapping and wound on roller V, and rollers III and IV respectively located on both sides below roller V. Roller I is provided on the side of roller III away from roller IV, and roller II is provided on the side of roller IV away from roller III. The first seedling belt and the second seedling belt form a clamp for the seedlings. The first seedling belt is wound around roller I from roller V downward through roller III, and the second seedling belt is wound around roller II from roller V downward through roller IV. Roller I and roller II are respectively connected to power devices. When the seedling separation device of the optimization scheme is in use, the seedlings are first clamped between the first seedling belt and the second seedling belt, with a certain distance between adjacent seedlings, and then the first seedlings and the second seedlings are wrapped around the roller V as a whole. During the transplanting operation, the power device drives the rollers I and II to rotate, and the first seedling belt and the second seedling belt are separated from the rollers III and IV, and the seedlings fall one by one to achieve seedling separation. The seedlings are clamped by the first seedling belt and the second seedling belt to avoid damage to the seedlings. It is convenient to separate the seedlings before the transplanting operation, thereby improving the efficiency of the transplanting operation.

[0007] As an optimization, adhesive sections are arranged at intervals on the opposite sides of the first seedling belt and the second seedling belt, and the adhesive sections on the first seedling belt are arranged opposite to the adhesive sections on the second seedling belt, and the intervals between the adhesive sections form a clamping gap for clamping the seedlings. This optimization scheme not only achieves the clamping of the seedlings and forms a barrier to the seedlings, ensures the interval between adjacent seedlings, but also bonds the first seedling belt and the second seedling belt together to prevent the first seedling belt and the second seedling belt from being misaligned or opened, causing the seedlings to fall.

[0008] As an optimization, roller I and roller II are respectively connected to the ground wheel. In the setting of this optimization scheme, when the ground wheel rotates with the movement of the transplanter, roller I and roller II are driven to rotate, ensuring the synchronization of the transplanter movement and seedling separation operation.

[0009] As an optimization, the seedling delivery device includes an annular conveyor belt rotatably arranged on a frame, and a plurality of seedling clamps installed on the conveyor belt and evenly distributed along the circumference of the conveyor belt. The movement trajectory of the seedling clamps passes directly below the seedling drop point of the seedling separation device and directly above the field ridges formed by the ridging device. When the seedling delivery device of this optimization scheme is working, the seedling clamps are driven to pass directly below the seedling drop point of the seedling separation device in sequence through the rotation of the conveyor belt, and when the seedling clamps move to directly below the seedling drop point of the seedling separation device, they receive the seedlings dropped from the seedling separation device, and as the conveyor belt rotates, the seedling clamps are delivered to the field ridges formed by the ridging device to achieve seedling delivery.

[0010] As an optimization, the seedling clamp includes a fixed plate fixedly connected to the outer side of the conveyor belt, and a movable splint and a fixed splint installed on the fixed plate and arranged opposite to each other, the fixed splint is fixedly connected to the fixed plate, the movable splint is hinged to the fixed plate through a horizontal axis, and a support arm extending to the inner side of the conveyor belt is also fixedly connected to the movable splint, and a roller located in the conveyor belt is rotatably installed on the support arm; the conveyor belt includes a seedling receiving section, a vertical section and a return section in sequence along the conveying direction, a support plate is fixedly provided at the rear of the vertical section, and the distance between the support plate and the vertical section is smaller than the distance between the roller and the conveyor belt when the seedling clamp is opened; the side of the movable splint away from the fixed splint is connected to the fixed plate by a spring. The seedling clamp of the optimized solution is in an open state when located at the seedling receiving section of the conveyor belt to receive the seedlings. When the seedling clamp moves to the vertical section, due to the setting of the support plate, the roller moves close to the conveyor belt, thereby pushing the movable clamp to rotate toward the fixed clamp, and the spring is stretched to achieve the closing of the opening of the seedling clamp, thereby clamping the seedlings to prevent the seedlings from falling when being transported downward; by setting the vertical section, vertical transportation of the seedlings is achieved, which facilitates the horizontal planting of the sweet potato seedlings.

[0011] As an optimization, the conveyor belt is connected to the ground wheel. The setting of this optimization scheme drives the conveyor belt to rotate through the ground wheel, ensuring the synchronization of the transplanter walking and the seedling transportation.

[0012] The present invention also provides a transplanting method using the above-mentioned fully automatic sweet potato seedling horizontal transplanter, including the following aspects:

[0013] 1. Place the seedlings in the clamping gap formed by the first seedling belt and the second seedling belt. The first seedling belt and the second seedling belt are bonded by the sticky section to prevent the seedlings from falling. Then, the first seedling belt and the second seedling belt holding the seedlings are wound around the roller V, and the movable end of the first seedling belt is passed downward around the roller III and then wound around the roller I. The movable end of the second seedling belt is passed downward around the roller IV and then wound around the roller II.

[0014] 2. The transplanter is driven forward by a tractor, and the ground wheel drives the main transmission shaft to rotate, and the main transmission shaft drives roller I, roller II and the conveyor belt to rotate; when roller I and roller II rotate, the clamped seedlings are transported downward, and when the seedlings reach the lower part between roller III and roller IV, they lose the clamping of the first seedling belt and the second seedling belt and fall into the seedling clamp; when the conveyor belt moves, it drives the seedling clamp to move from the seedling receiving section to the vertical section. When the seedling clamp moves to the vertical section, under the action of the support plate, the roller moves close to the conveyor belt, thereby driving the movable splint to rotate toward the fixed splint, so that the seedling clamp clamps the seedlings, and the spring is stretched; when the seedling clamp moves from the vertical section to the return section, the support plate loses the blocking of the roller, and the movable splint rotates away from the fixed splint under the action of the spring, loses the clamping of the seedlings, and places the seedlings horizontally on the ridge;

[0015] 3. The seedlings planted on the ridges are compacted by the soil pressing wheel installed at the rear end of the frame to achieve seedling transplanting.

[0016] The beneficial effects of the present invention are:

[0017] 1. The seedling separation device is used to automatically place the sweet potato seedlings into the seedling clamps one by one. By opening and closing the seedling clamps, the sweet potato seedlings are horizontally planted on the ridges, realizing the fully automatic transplanting of the sweet potato seedlings, which not only completely liberates the labor force, but also greatly improves the efficiency of sweet potato transplanting;

[0018] 2. The sweet potato seedlings are transported by a seedling delivery device. Since the seedling clamp is perpendicular to the field ridge, the sweet potato seedlings can be planted horizontally and densely planted, which not only better meets the agronomic requirements of sweet potato planting, but also improves the economic benefits of sweet potato planting.

[0030] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0031] like Figures 1 to 3 The fully automatic sweet potato seedling horizontal transplanter shown in the figure comprises a frame 1 equipped with a ground wheel 21, and a rotary tillage device, a ridging device 20, a seedling delivery device and a soil pressing wheel 24 sequentially installed on the frame from front to back, the seedling delivery device has a seedling drop point that matches the ridging device, and a seedling separation device is provided above the seedling delivery device, and the seedling drop point of the seedling separation device matches the seedling delivery device. The frame 1 is used to fix and support other parts, and is hung on agricultural implements such as tractors through a suspension frame 17, and the suspension frame is installed above the rotary tillage device; a gearbox 16 and a seedling placement plate 19 are also provided on the frame, and the gearbox 16 provides power to the rotary tillage device through a belt drive.

[0032] The rotary tillage device includes a rotary tillage shaft 2 and a rotary tillage blade 3 installed on the rotary tillage shaft. A pulley 25 is installed at one end of the rotary tillage shaft. The pulley 25 is connected to the output shaft of the gearbox through a belt 6. The belt drive drives the rotary tillage shaft 2 and the rotary tillage blade 3 to rotate for land reclamation and loosening.

[0033] The ridging device 20 is installed behind the rotary tillage device to ridge the loosened soil and ensure the accuracy of the seedling placement position of the seedling delivery device. The structure of the ridging device adopts the existing technology.

[0034] like Figure 2 and Fig. 9As shown, the seedling separation device is installed on the upper frame of the seedling delivery device, and the seedling separation device includes a roller V33, a first seedling belt and a second seedling belt overlapped and wound on the roller V, and rollers III29 and IV30 respectively located on both sides below the roller V. The side of the roller III away from the roller IV is provided with a roller I32, and the side of the roller IV away from the roller III is provided with a roller II31. The first seedling belt and the second seedling belt form a clamp for the rice seedlings. The first seedling belt is wound on the roller I after passing through the roller III from the roller V downward, and the second seedling belt is wound on the roller II after passing through the roller IV from the roller V downward. The rollers I and II are respectively connected to the power device, and the seedling drop point of the seedling separation device is between the rollers III and IV. The roller V is located between the rollers I and II, and the rotation direction of the roller V is opposite to that of the rollers I and II. When the roller V rotates, the clamping belt 14 formed by the first seedling belt and the second seedling belt is unwound, and when the rollers I and II rotate, the first seedling belt and the second seedling belt are respectively wound.

[0035] Roller I and roller II are respectively connected to the ground wheels by transmission, and the two ground wheels on the frame are fixedly installed at both ends of the main transmission shaft 18. The main transmission shaft is connected to the frame through bearings, and the main transmission shaft 18 is respectively connected to roller I and roller II by chain transmission. Specifically, the barrel shaft 26 of roller I and the barrel shaft 10 of roller II are respectively installed on the frame 1 through bearing seats, and the barrel shaft 26 of roller I is fixedly connected with a driven sprocket I 28 through a key, and the barrel shaft 10 of roller II is fixedly connected with a driven sprocket II 22 through a key. The main transmission shaft 18 is installed with a driving sprocket II 34 connected to the driven sprocket II 22 through a chain transmission, and a driving sprocket I 27 connected to the driven sprocket I 28 through a chain transmission.

[0036] In order to improve the reliability of the seedling separation device in clamping the seedlings, adhesive segments are arranged at intervals on the opposite sides of the first seedling belt and the second seedling belt, and the adhesive segments on the first seedling belt are arranged opposite to the adhesive segments on the second seedling belt. The intervals between the adhesive segments form clamping seams for clamping the seedlings, and the seedlings are clamped in the clamping seams at equal intervals. The first seedling belt and the second seedling belt are bonded by the adhesive segments to ensure the reliability of the seedling clamping. The bonded adhesive segments are separated at rollers III and IV to facilitate the seedlings to fall. When making the first seedling belt and the second seedling belt, the adhesive belt can be used as the base belt, and the adhesive layer of the adhesive belt can be removed at intervals. The adhesive layer at the unremoved position forms an adhesive segment, and the position where the adhesive layer is removed is the position of the clamping seam.

[0037] The seedling delivery device includes an annular conveyor belt 7 rotatably arranged on a frame, and a plurality of seedling clamps 11 installed on the conveyor belt 7 and evenly distributed along the circumference of the conveyor belt. The seedling clamps are arranged at equal intervals. As the conveyor belt moves, the movement trajectory of the seedling clamps passes directly below the seedling drop point of the seedling separation device and directly above the ridge formed by the ridging device. When the seedling clamp is located directly below the seedling drop point of the seedling separation device, the opening of the seedling clamp faces upward to receive the seedlings. When the seedling clamp is located directly above the ridge formed by the ridging device, the opening of the seedling clamp faces downward to release the seedlings. The spacing distance of the seedlings is adapted to the spacing distance of the seedling clamps to ensure that the seedlings fall into the seedling clamps when they fall.

[0038] Specifically, the seedling clamp includes a fixed plate fixed to the outer side of the conveyor belt by bolts, and a movable clamp and a fixed clamp installed on the fixed plate and arranged oppositely. The clamping opening of the seedling clamp formed by the fixed clamp and the movable clamp extends in the horizontal direction and is perpendicular to the field ridge to achieve horizontal planting of sweet potato seedlings. The fixed clamp is fixedly connected to the fixed plate, and the movable clamp is hinged to the fixed plate through a horizontal axis. A support arm extending to the inner side of the conveyor belt is also fixed to the movable clamp, and a roller 12 located in the conveyor belt is rotatably installed on the support arm. The conveyor belt includes a seedling receiving section, a vertical section and a return section in sequence along the conveying direction. A support plate 13 is fixed behind the vertical section. The distance between the support plate 13 and the vertical section is less than the distance between the roller and the conveyor belt when the seedling clamp is opened. The support plate 13 is vertically fixed on the frame 1 through a bearing seat 9 and a seedling delivery support frame 15. The seedling receiving section is horizontally arranged. When the seedling clamp is located in the seedling receiving section, the connection point between the support arm and the movable clamp is located behind the horizontal axis, and the support arm extends backward in an inclined manner. The side of the movable clamp away from the fixed clamp is connected to the fixed plate through the spring 4. When the seedling clamp is located in the seedling receiving section and the return section, the spring is in a natural state. When the seedling clamp is located in the vertical section, the spring is in a stretched state. When the seedling clamp 11 moves to the vertical position of the conveyor belt 7, the roller 12 of the seedling clamp reaches the support plate 13, the seedling clamp 11 is closed, and the spring 4 is stretched. When the seedling clamp 11 moves above the ridge surface, the seedling clamp roller 12 is separated from the support plate 13, the spring 4 contracts, and the seedling clamp 11 is released, and the seedling is placed horizontally on the ridge.

[0039] The conveyor belt is connected to the ground wheel by transmission. Specifically, the conveyor belt is supported by a driving wheel 23 and two supporting wheels, and the driving wheel 23 and the two supporting wheels are distributed in a right triangle. The driving wheel is located at the lower end of the right angle side, and the wheel shaft 8 of the driving wheel is installed on the frame through the bearing seat 9 and the seedling support frame 15. The driven sprocket III 35 and the driven sprocket IV 36 are installed on the wheel shaft 8 of the driving wheel through a key connection. The main transmission shaft 18 is equipped with a driving sprocket III 37 connected to the driven sprocket III 35 by a chain, and a driven sprocket IV 5 connected to the driven sprocket IV 36 by a chain, and the power of the main transmission shaft 18 is transmitted to the wheel shaft 8 of the driving wheel, and the driving wheel 23 drives the conveyor belt 7 to rotate.

[0040] There are two coaxially arranged ground wheels 21, which are installed on the frame 1 through the main transmission shaft 18, and are used to support the frame 1 and drive the machine forward. The movement of the ground wheels 21 drives the main transmission shaft 18 to rotate, and the main transmission shaft 18 provides power to each driving sprocket. Each driving sprocket and each driven sprocket are connected by a chain, thereby driving the seedling delivery device and the seedling separation device to move.

[0041] The soil pressing wheels 24 are installed on both sides of the rear of the frame 1 and are located in the same straight line as the seedling clamps 11; the soil pressing wheels 24 are installed on the soil pressing wheel shaft and are connected to the frame 1, contacting the ridge surface to compact the seedlings planted on the ridge.

[0042] The transplanting method using the fully automatic sweet potato seedling horizontal transplanter of this embodiment includes the following aspects:

[0043] 1. Place the seedlings in the clamping gap formed by the first seedling belt and the second seedling belt. The first seedling belt and the second seedling belt are bonded by the sticky section to prevent the seedlings from falling. Then, the first seedling belt and the second seedling belt holding the seedlings are wound around the roller V, and the movable end of the first seedling belt is passed downward around the roller III and then wound around the roller I. The movable end of the second seedling belt is passed downward around the roller IV and then wound around the roller II.

[0044] 2. The tractor is connected to the frame 1 of the transplanter through the suspension frame 17. The tractor drives the transplanter forward, and the ground wheel drives the main transmission shaft to rotate. The main transmission shaft drives the rollers I, II and the conveyor belt to rotate. When the rollers I and II rotate, the clamped seedlings are transported downward. When the seedlings reach the lower part between the rollers III and IV, the first seedling belt and the second seedling belt are separated and lose the clamping of the first seedling belt and the second seedling belt. At this time, the seedling clamp is just below the fallen seedlings, so that the seedlings fall into the seedling clamp. When the conveyor belt moves, it drives the seedling clamp to move from the seedling receiving section to the vertical section. When the seedling clamp moves to the vertical section, under the action of the support plate, the roller moves close to the conveyor belt, thereby driving the movable clamp to rotate toward the fixed clamp, so that the seedling clamp clamps the seedlings, and the spring is stretched; when the seedling clamp moves from the vertical section to the return section, the support plate loses the blocking of the roller, and the movable clamp rotates away from the fixed clamp under the action of the spring, the seedling clamp opens, loses the clamp on the seedling, and the seedling is placed horizontally on the ridge;

[0045] 3. The soil pressing wheel installed at the rear end of the frame compacts the seedlings planted on the ridges to achieve transplanting of the seedlings and finally complete the transplanting operation, which not only realizes the mechanized transplanting of sweet potatoes, but also meets the agronomic requirements of horizontal planting of sweet potatoes;

[0046] 4. After the seedlings have fallen, directly remove the first and second seedling tapes from the drum, and replace them with another set of seedling tapes. Put the seedlings back on the removed seedling tapes and wait for the next round of transplanting.

[0047] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention, and should also fall within the scope of protection of the claims of the present invention.
