Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, specifically to a zero-speed crop transplanter that does not require reversing and its method of use. Background Technology

[0002] Current planting technologies generally involve seed implantation and seedling implantation. Compared to direct seed planting, farmers can shorten the crop growth period and increase crop survival rate by implanting commercial seedlings into the soil, while also reducing the impact of natural disasters and pests on the seed germination and growth process. Traditional seedling transplanting machinery uses complex seedling placement mechanisms to ensure the uprightness of seedlings after transplanting, but it still cannot achieve absolute zero-degree seedling placement or the absolute zero-speed seedling placement time is too short. This results in relative movement between the seedling and the farmland during the transplanting process, and the only way to ensure the relative uprightness of the seedlings after transplanting is to reduce the speed of the machinery. Furthermore, some agricultural machinery still requires manual straightening of some crop seedlings after transplanting. Although some existing technologies can guarantee zero-speed seedling placement time and seedling uprightness, the machinery needs to repeatedly reverse the seedlings during the placement process, resulting in complex mechanisms, poor reliability, and easy damage to the seedlings, which affects their later development.

[0003] Therefore, in order to address the aforementioned shortcomings, designing a simple and reliable high-speed continuous zero-speed seedling delivery mechanism for crops, simplifying the mechanism's complexity, and improving transplanting speed and uprightness are urgent technical problems that need to be solved.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0026] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0028] The invention will now be described in further detail with reference to the accompanying drawings. The invention provides a zero-speed, non-reversible crop transplanter, such as... Figure 1 As shown, the machine includes a frame 9. In this embodiment, one end of the frame 9 is provided with a transplanting mechanism 6. Preferably, two transplanting mechanisms 6 are provided in this embodiment, but it is not limited to this. The number of transplanting mechanisms 6 can be increased or decreased as needed. The transplanting mechanism 6 is connected to the soil covering mechanism 4. The transplanting mechanism 6 is connected to the drive mechanism through the transmission mechanism 2. The seedling feeding mechanism 8 is provided on the frame 9 and cooperates with the transplanting mechanism 6 to transport the potted seedlings to the transplanting mechanism 6. The frame 9 is also provided with a steering mechanism 5.

[0029] In this embodiment, as shown Figure 2 and Figure 3 The diagram shown is of the transplanting mechanism 6, which includes the entire transplanting frame 61. Both the front and rear ends of the transplanting frame 61 are equipped with soil covering mechanisms 4. Figure 2 As shown, the transplanting frame 61 is made of welded profiles, and the entire transplanting mechanism 6 is fitted onto the front beam of the frame 9 by the connecting sleeve 62.

[0030] The transplanting frame 61 has a first support sprocket group 65 and a second support sprocket group 66 at its left and right ends, respectively. The first support sprocket group 65 has four support sprockets, which are respectively set at the four corners of one side of the transplanting frame 61. Each support sprocket is sleeved on a rotating shaft. One end of the rotating shaft passes through the support sprocket, and the other end is rotatably connected to the bearing seat set on the transplanting frame 61 through a bearing. A first chain 64 is sleeved on the first support sprocket group.

[0031] The second support sprocket group 66 contains four support sprockets respectively located at the four corners of the other side of the transplanting frame 61. Each support sprocket is mounted on a rotating shaft. One end of the rotating shaft passes through the support sprocket, and the other end is rotatably connected to the bearing seat located on the transplanting frame 61 via a bearing. A second chain 63 is mounted on the second support sprocket group 66.

[0032] In this embodiment, the first support sprocket group 65 and the second support sprocket group 66 are set on different axes. The four support sprockets of the first support sprocket group 65 are higher than the four support sprockets of the second support sprocket group 66, with a height difference of 15mm. This ensures that the first chain 64 and the second chain 63 also have a height difference, ensuring that the seedling feeder only moves in translation during movement and always remains perpendicular to the ground, thus ensuring the uprightness of the seedlings after transplanting.

[0033] In this embodiment, as shown Figure 2 As shown, the support sprockets located in the upper left corner of the first support sprocket group 65 and the second support sprocket group 66 are rotatably connected to the first transmission sprocket 67 and the second transmission sprocket 68 via a rotating shaft. The first transmission sprocket 67 and the second transmission sprocket 68 are connected to the transmission mechanism 2. The transmission mechanism 2 drives one of the support sprockets in the first support sprocket group 65 and the second support sprocket group 66 to rotate, thereby driving the first chain 64 and the second chain 63 to rotate.

[0034] In this embodiment, the push plates include a first push plate 69 and a second push plate 610 located at both ends of the seedling feeder, such as Figure 2 As shown, the first push plate 69 and the second push plate 610 are located between the first chain 64 and the second chain 63, and a seedling feeder is provided between the first push plate 69 and the second push plate 610.

[0035] This implementation example Figure 4 Taking the first push plate 69 as an example, the first push plate 69 consists of four sections, namely the far rest section 618, the push section 619, the near rest section 620, and the return section 621. The following is a detailed explanation in conjunction with the structure of the seedling feeder.

[0036] This embodiment Figure 4 The seedling feeder shown includes a hanging cup 611 and a duckbill 616 located at the bottom of the hanging cup 611. Two duckbills 616 are respectively located at the left and right ends of the hanging cup 611. Each duckbill 616 is provided with a connecting block 617. The fixing pins 622 provided on the two connecting blocks 617 are respectively installed in conjunction with the first chain 64 and the second chain 63, and the shaft ends are positioned by elastic retaining rings. A rotating block is connected to the connecting block 617. The two rotating blocks are connected by a torsion spring 614. Each rotating block is provided with a push rod 615 on its top.

[0037] Throughout the transplanting process, the state of the spout 616 of the seedling feeder is sequentially closed-held – open – open-held – closed – closed-held. When the seedling feeder moves with the first chain 64 and the second chain 63, when it reaches the far resting section 618 of the first push plate 69 and the second push plate 610, the two push rods 615 on the seedling feeder contact the first push plate 69 and the second push plate 610 respectively. When it continues to move to the pushing section 619 of the first push plate 69 and the second push plate 610, the two push rods 615 are squeezed, thereby opening the spout 616. This process is completed in the soil. Since the pushing section 619 of the first push plate 69 and the second push plate 610 is relatively gentle, it can avoid opening too quickly and causing excessive impact vibration.

[0038] After the duckbill 616 opens, the plane where the first push plate 69 and the second push plate 610 are located near the resting section 620 remains open until the push rod 615 reaches the return section 621 of the first push plate 69 and the second push plate 610. At this time, the duckbill 616 closes under the action of the torsion spring 614. This process is completed when the duckbill 616 is completely away from the position of the seedling in the pot, thus avoiding the seedling from being pinched during the closing process of the duckbill 616. The entire transplanting process is thus completed.

[0039] In this embodiment, the first drive sprocket 67 in the first support sprocket group and the second drive sprocket 68 in the second support sprocket group are connected to the transmission mechanism 2. The transmission mechanism 2 is also connected to the drive wheel 26 in the device. In this embodiment, the device operates in a backward motion. The rotation direction of the drive wheel 26 is opposite to the transmission direction of the first chain 64 and the second chain 63 to achieve the seedling planting process. Throughout the entire movement, the linear velocities of the first drive sprocket 67, the second drive sprocket 68, and the drive wheel 26 are consistent, i.e., v 26 =v 65 =v 鸭嘴 This allows for zero-speed seedling placement.

[0040] like Figure 1 As shown, in this embodiment, the first row spacing adjustment mechanism 3 is used to adjust the transplanting mechanism 6. A C-shaped connector is sleeved on the seedling guide tube 85. The seedling guide tube 85 is welded to the nut seat 31 through the C-shaped connector. The nut seat 31 is also welded to the transplanting frame 61. The nut seat 31 is sleeved on the rotating screw. One end of the rotating screw is connected to a second adjustment handle 32. By manually rotating the second adjustment handle 32, the rotating screw is driven to rotate, so that the nut seat 31 moves on the rotating screw, thereby driving the frame 61 to move along the rotating screw, so as to adjust the spacing between the two transplanting frames 61.

[0041] like Figure 2The diagram shown is a schematic of the soil covering mechanism 4 of this device. The soil covering mechanism 4 includes a soil covering frame 41, a height adjustment device mounted on the soil covering frame 41, and a soil covering wheel 45 connected to the height adjustment device. The height of the soil covering wheel 45 can be adjusted by the height adjustment device. The height adjustment device includes a first adjustment handle 42 and a first threaded rod 43 connected to the first adjustment handle 42. The first threaded rod 43 passes through a first threaded sleeve 44 and is rotatably connected to the first threaded sleeve 44. A nut is also provided between the first threaded rod 43 and the first threaded sleeve 44. In this embodiment, two covering wheels 45 are preferably assembled on a spherical connection of a covering shaft. The spherical connection of the covering shaft is connected to the bottom of the first threaded rod 43. The covering wheels 45 can move up and down without rotating. In this embodiment, the two covering wheels 45 form a 15° angle with the vertical plane where the first threaded rod 43 is located along the X-axis and a 75° angle with the horizontal plane where the first threaded rod 43 is located along the Z-axis. The set angle can improve the covering effect.

[0042] In this embodiment, the transplanting mechanism 6 has two soil covering mechanisms 4 at the front and back, each with a different function. During the transplanting process, if the soil encountered is too loose, the soil covering mechanism 4 at the front is lowered to fix the soil before transplanting the seedlings. After transplanting, the soil covering mechanism 4 at the rear is used to fix the soil a second time to ensure transplanting efficiency. If the soil moisture is moderate, the soil covering mechanism 4 at the front can be completely retracted and will not work.

[0043] This implementation example Figure 5 The diagram shows the transmission mechanism 2, which includes two drive mechanisms, each corresponding to one of the two transplanting mechanisms 6. In this embodiment, the drive mechanism can be a motor 21 or an internal combustion engine connected to a reducer 22. In this embodiment, the motor 21 is preferred.

[0044] Since each transplanting mechanism 6 in this embodiment corresponds to a transmission mechanism 2, the following description will only use one transmission mechanism 2 as an example.

[0045] The output end of the reducer 22 is connected to a first sprocket 27 and a second sprocket 23, which are coaxially arranged. The second sprocket 23 is connected to a third sprocket 24 via a chain. A tension wheel 25 is also provided between the second sprocket 23 and the third sprocket 24. In this embodiment, the third sprocket 24 is sleeved on the drive shaft, which includes a first drive shaft 54 ​​and a second drive shaft 55. The other ends of the first drive shaft 54 ​​and the second drive shaft 55 are both connected to a drive wheel 26 that drives the entire mechanism forward.

[0046] In this embodiment, the first sprocket 27 is connected to the fourth sprocket 28 via a chain, and the fourth sprocket 28 is coaxially connected to the fifth sprocket 29, such as... Figure 5As shown, the fifth sprocket 29 is a large sprocket, which is connected to a drive sprocket (not shown in the figure) via a chain. The drive sprocket has three sprockets coaxially arranged: the third drive sprocket 210, the fourth drive sprocket (not shown in the figure), and the fifth drive sprocket. The first drive sprocket 67 is connected to the third drive sprocket 210 via a chain, and the second drive sprocket 68 is connected to the fourth drive sprocket via a chain. The third drive sprocket 210 drives the first drive sprocket 67 to rotate, and the second drive sprocket 68 drives the fourth drive sprocket to rotate, thereby driving the first chain 64 and the second chain 63 to rotate.

[0047] like Figure 5 The diagram also includes a body adjustment mechanism 1, which allows for the adjustment of the height of the frame 9. In this embodiment, the body adjustment mechanism 1 includes an adjustment handwheel 11, an adjustment screw 12, and an adjustment sleeve 13. The adjustment handwheel is connected to the adjustment screw 12, which passes through and is rotatably connected to the adjustment sleeve 13. A nut is also provided between the adjustment screw 12 and the adjustment sleeve 13. The adjustment screw 12 is connected to a grooved connector, which is connected to the frame 9. Rotating the adjustment screw 12 adjusts the height of the frame 9. In this embodiment, the body adjustment mechanism 1 and the height adjustment device of the soil covering mechanism 4 work together to adjust the transplanting depth during the transplanting process.

[0048] like Figure 7 The diagram shows the seedling feeding mechanism 8 of this device, which includes a seedling tray 82 and a seedling feeding tray 83 arranged vertically. The seedling tray 82 and the seedling feeding tray 83 are spaced apart. The seedling tray 82 has several through holes, each corresponding to a seedling cup 81. The seedling feeding tray 83 has an opening connected to a seedling feeding port 84. The seedling feeding port 84 is a groove-shaped opening with an upper arc and a lower circular funnel shape, ensuring the vertical feeding of the seedlings without affecting the feeding process.

[0049] The other end of the seedling inlet 84 is connected to the seedling guide tube 85, through which the seedlings enter the hanging cup 611 in the seedling feeder. In this embodiment, the seedling feeding mechanism 8 is also provided with a rotating shaft 86. One end of the rotating shaft 86 extends to the outside of the seedling tray 82 and the seedling feeding tray 83 and is rotatably connected to the seedling tray 82. The other end is connected to the first bevel gear (not shown in the figure). The first bevel gear meshes with the second bevel gear. Both the first bevel gear and the second bevel gear are located in the gearbox 87. The second bevel gear is coaxially connected to the sixth sprocket 88, which is connected to the fifth transmission sprocket via a chain.

[0050] Seedlings are manually placed into seedling cups 81, which are fixed on seedling trays 82. The fifth transmission sprocket in the transmission mechanism 2 drives the sixth sprocket 88 to rotate, which in turn drives the second and first bevel gears to rotate, thereby driving the rotating shaft 86 to rotate. The rotating shaft 86 drives the seedling tray 82 to rotate. When the seedling tray 82 rotates, the seedlings in the seedling cups 81 rotate with the seedling tray 82. When the seedling tray 82 rotates to the seedling inlet 84 of the seedling tray 8382, the seedlings fall into the seedling guide tube 85.

[0051] In this embodiment, the second row spacing adjustment mechanism is used to adjust the seedling feeding mechanism 8. The bottom of the gearbox 87 is connected to a first slider, which is mounted on a guide rail on the frame 9. The first slider is connected to a second slider through a connecting plate. The second slider is mounted on another guide rail on the frame 9. The second slider is also connected to a transmission screw, and one end of the transmission screw is connected to a third adjustment handle.

[0052] Manually rotating the three-way adjustment handle drives the second slider to move on the guide rail via the transmission screw, which in turn drives the first slider to move on the guide rail as well. The first slider drives the gearbox 87 to move, which in turn drives the seedling feeding mechanism 8 to move left and right to adjust the row spacing. Since the seedling guide tube 85 is connected to the nut seat 31 in the first row spacing adjustment mechanism 3, when adjusting the first row spacing adjustment mechanism and the second row spacing adjustment mechanism, the position of the seedling guide tube 85 can be ensured to correspond with that of the seedling feeder, thus ensuring that the potted seedlings can enter the seedling feeder through the seedling guide tube 85.

[0053] In this embodiment, the height adjustment devices of the first row spacing adjustment mechanism 3, the soil covering mechanism 4, and the second row spacing adjustment mechanism can all be adjusted individually according to specific use. However, the body adjustment mechanism 1 in this embodiment needs to be adjusted together with the height adjustment device of the soil covering mechanism 4 to change the transplanting depth.

[0054] like Figure 6 The diagram shown is a bottom view of the device, which includes a steering mechanism 5, including a steering wheel 53 and a hydraulic motor 51; the output end of the hydraulic motor 51 is connected to a hydraulic rod 52, and the hydraulic rod 52 is connected to the steering wheel 53 through a thrust bearing.

[0055] In practical use, when this device is in reverse mode, the purpose is to facilitate observation of the quality of the seedlings after transplanting at the front end. In this embodiment, it is driven by two motors 21. When working, the steering wheel 53 is retracted and the two motors 21 work simultaneously. When moving forward, the power of the motors 21 is output to the front transplanting mechanism 6 of the frame 9.

[0056] When a turn is required, the hydraulic motor 51 operates, causing the hydraulic rod 52 to extend. A thrust bearing is fitted between the steering wheel 53 and the hydraulic rod 52, allowing the steering wheel 53 to rotate in contact with the ground. At this time, the hydraulic rod 52 extends, causing the transplanting mechanism 6 at the front end of the device to lift up until the transplanting mechanism 6 is completely off the ground.

[0057] When a left turn is required, one of the motors 21 operates, driving the coaxially connected drive wheel 26 to rotate via the chain drive first drive shaft 54, thus achieving a left turn; when a right turn is required, the other motor 21 operates, driving the coaxially connected drive wheel 26 to rotate via the chain drive second drive shaft 55, thus achieving a right turn.

[0058] This device cannot move forward while in operation, otherwise it will damage the transplanting mechanism 6. When not in operation, the chain connected to the transplanting mechanism 6 at the front end can be removed for normal movement, so as to quickly transfer and improve work efficiency.

[0059] like Figure 1 As shown, the frame 9 in this embodiment is also provided with a tray 7 for placing seedlings and a seat for workers to rest.

[0060] When this device is in use, the motor 21 provides power to move the device. While moving, the seedlings are manually placed into the seedling cups 81. The fifth transmission sprocket in the transmission mechanism 2 rotates, driving the sixth sprocket 88 to rotate, which in turn drives the second and first bevel gears to rotate, thereby driving the rotating shaft 86 to rotate. The rotating shaft 86 rotates, driving the seedling tray 82 to rotate. When the seedling tray 82 rotates, the seedlings in the seedling cups 81 rotate with the seedling tray 82. When the seedling tray 82 rotates to the seedling inlet 84 of the seedling tray 83, the seedlings fall into the seedling guide tube 85. The seedlings fall from the seedling guide tube 85 into the seedling feeder. The third and fourth transmission sprockets in the transmission mechanism 2 drive the first transmission sprocket 67 and the second transmission sprocket 68 to rotate, thereby driving the first chain 64 and the second chain 63 to rotate, driving the seedling feeder to rotate. The seedling feeder rotates by closing-opening-closing to feed the seedlings, completing the transplanting process.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

A rotating block is connected to the connecting block (617) and connected to it by a torsion spring (614). The top of the rotating block is also provided with a push rod (615). The push rod (615) cooperates with a push plate provided on the transplanting frame (61). The push rod (615) contacts the push plate, which drives the duckbill (616) to open. The push plate includes a first push plate (69) and a second push plate (610) at both ends of the seedling feeder. The first push plate (69) and the second push plate (610) are located between the first chain (64) and the second chain (63). The seedling feeder is located between the first push plate (69) and the second push plate (610). The transmission assembly includes a first chain (64) and a second chain (63). Both the first chain (64) and the second chain (63) are connected to the fixed pin (622). The first chain (64) and the second chain (63) drive the seedling feeder to move. When the seedling feeder moves with the first chain (64) and the second chain (63), when it moves to the far resting section (618) of the first push plate (69) and the second push plate (610), the two push rods 615 on the seedling feeder contact the first push plate (69) and the second push plate (610) respectively. When it continues to move to the first push plate 610, the two push rods 615 on the seedling feeder contact the first push plate (69) and the second push plate (610) respectively. When the second push plate (610) is in the pushing stroke (619), the two push rods (615) are squeezed, thereby opening the duckbill (616). This process is completed in the soil. After the duckbill (616) is opened, the plane where the first push plate (69) and the second push plate (610) are near the resting section (620) remains open until the push rod 615 reaches the return stroke (621) of the first push plate (69) and the second push plate (610). Then the duckbill (616) closes under the action of the torsion spring (614). This process is completed when the duckbill (616) is completely away from the position of the seedling in the pot. The first chain (64) is fitted onto the first support sprocket assembly (65) located within the transplanting frame (61), and the second chain (63) is fitted onto the second support sprocket assembly (66) located within the transplanting frame (61).

7. The method of using a zero-speed crop transplanter without reversing as described in any one of claims 1 to 6, characterized in that, include: The motor provides power to move the device. Simultaneously, a person manually places a seedling into a seedling cup. The fifth transmission sprocket in the transmission mechanism rotates, driving the sixth sprocket, which in turn drives the second and first bevel gears, thus rotating the rotating shaft. The rotating shaft then drives the seedling tray to rotate. As the tray rotates, the seedlings in the seedling cups rotate with it. When the tray reaches the seedling inlet of the seedling tray, the seedlings fall into the guide tube. From the guide tube, the seedlings fall into the seedling feeder. The third and fourth transmission sprockets in the transmission mechanism drive the first and second transmission sprockets, which in turn drive the first and second chains, causing the seedling feeder to rotate. The seedling feeder rotates by closing and opening and closing, thus completing the transplanting process.
