Description

Technical Field

[0001] The present invention relates to the technical field of bare seedling transplanting, and particularly to a bare seedling planting device applicable to multiple power sources. Background Art

[0002] At present, the main bare seedling planting devices are finger clip type transplanting machines, disk clip type transplanting machines and chain clip type transplanting machines. Among them, the finger clip type transplanting machine and the disk clip type transplanting machine are towed by a large horsepower tractor and obtain power through the rear power output shaft of the tractor. This operation method requires the tractor to have a specific climbing gear, and the transplanting plant spacing needs to be adjusted in advance according to the climbing gears of different tractors. At the same time, its turning radius at the end of the field is large, and it cannot meet the tillage requirements of small plot areas.

[0003] In addition, a ground wheel driven chain clip type ditch opening bare root seedling transplanting machine is disclosed in the prior art. Although it solves the problem that the plant spacing needs to be specifically adjusted, it is mainly applicable to bare ridge planting and has a single application mode. There is also a small type belt clip type transplanting machine, which integrates the planting unit with a self-propelled gasoline engine, and overall arranges the speed ratio relationship between the whole machine transportation and the operation plant spacing speed for small plot field operations to achieve bare seedling planting in small plots. However, since the planting monomer is integrated with the power unit and the self-propelled system, the cost is greatly increased, which limits the use and popularization of the machine. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a bare seedling planting device applicable to multiple power sources, which can be matched with multiple types of tractors, is suitable for various cultivation modes, and can ensure stable plant spacing and sufficient power.

[0005] In order to achieve the above purpose, the present invention is realized by the following technical solutions:

[0006] An embodiment of the present invention provides a bare seedling planting device applicable to multiple power sources, including a first-stage transmission assembly. One side of the first-stage transmission assembly is rotationally connected to the left-side transmission assembly, and the other side is rotationally connected to the right-side transmission assembly. The left-side transmission assembly is installed with a seedling carrying and ridge entering and taking device, and the right-side transmission assembly is connected to the seedling feeding assembly;

[0007] The first-stage transmission assembly includes a housing A. One end of the housing A is installed with a shaft C connecting the left-side transmission assembly and the right-side transmission assembly, and the other end is installed with a shaft A for connecting the input power. The shaft A and the shaft C are connected by a chain transmission mechanism, and the shaft C is connected to a servo motor through a gear transmission mechanism.

[0008] As a further implementation method, a torque limiter is installed on the shaft C. One end of the shaft C is connected to the left-side transmission assembly through a sprocket C, and the other end is connected to the right-side transmission assembly through a sprocket B.

[0009] As a further implementation method, the left transmission assembly includes a housing B. One end of the housing B is rotatably connected to a rotating sleeve A, and the other end is connected to a shaft D. The shaft D is connected to one end of a chain B through a sprocket D, and the other end of the chain B is connected to a sprocket C. Moreover, the rotating sleeve A is connected to a shaft C through a bearing C.

[0010] As a further implementation method, an installation plate for installing a seedling-carrying and ridge-planting device is fixed to the outside of the housing B.

[0011] As a further implementation method, the right transmission assembly includes a housing C. One end of the housing C is rotatably connected to a rotating sleeve B, and the other end is installed with a shaft E. The shaft E is connected to one end of a chain C through a sprocket E, and the other end of the chain C is connected to a sprocket B. Moreover, the rotating sleeve B is connected to a shaft C through a bearing G.

[0012] As a further implementation method, a seedling-feeding assembly is installed on the outside of the housing C through a fixing plate.

[0013] As a further implementation method, the seedling-feeding assembly includes a seedling-feeding frame and a sprocket group installed on the seedling-feeding frame. The sprocket group supports a pair of seedling-feeding chains so that the pair of seedling-feeding chains forms an inverted isosceles trapezoid structure. The pair of seedling-feeding chains is connected to a chain driving mechanism.

[0014] As a further implementation method, a tensioning sprocket group is installed at one end of the top of the seedling-feeding frame, a driven sprocket group is installed at the other end, and a supporting sprocket group A is installed in the middle. A plurality of groups of supporting sprocket groups B are installed at intervals at the bottom of the seedling-feeding frame. The tensioning sprocket group, the driven sprocket group, the supporting sprocket group A, and the supporting sprocket group B jointly support the pair of seedling-feeding chains.

[0015] As a further implementation method, the driven sprocket group is connected to the chain driving mechanism. The chain driving mechanism includes a gearbox installed on the seedling-feeding frame and a driving sprocket group connected to the gearbox. The driving sprocket group and the driven sprocket group are connected through a chain D.

[0016] As a further implementation method, the seedling-feeding frame has a T-shaped structure.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) The power part of the bare-seedling planting device of the present invention includes a primary transmission assembly, a left transmission assembly, and a right transmission assembly. Its power can be provided independently by the ground wheel of a supporting machine tool or can also be provided independently by a servo motor to achieve plant spacing adjustment. By transmitting power through the primary transmission assembly, the left transmission assembly, and the right transmission assembly, sufficient power can be ensured.

[0019] (2) The primary drive assembly, left drive assembly, and right drive assembly of the present invention mainly consist of sprockets, shafts, bearings, and chains.

[0020] (3) On both sides of the primary drive assembly of the present invention, the rear ends of the left drive assembly and the right drive assembly are respectively fixedly installed on the frame of the seedling feeding assembly. The left drive assembly and the right drive assembly can rotate simultaneously around the fixed installation points with the primary drive assembly. The depth-limiting and soil-covering device is fixedly installed at the rearmost part of the device and jointly forms a hinged profiling mechanism with the left drive assembly and the right drive assembly, thereby enabling the seedling-carrying and ridge-inserting and planting device to achieve profiling along with the undulations of the field ridges.

[0021] (4) The seedling feeding chain of the present invention forms an inverted isosceles trapezoid structure through the seedling feeding frame, which can avoid the installation frame matching the seedling feeding assembly; at the same time, while designing the structure, the length of the seedling feeding chain pair and the number of bare-seedling feeding plates are increased as much as possible. Under the condition of the same planting frequency, the artificial seedling placement space is larger and it is more convenient for artificial seedling placement. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation

[0039] Example 1:

[0040] This example provides a bare seedling planting device applicable to multiple power sources, as Figure 1 and Figure 2 shown, including a first-stage transmission assembly 1, a left-side transmission assembly 2, a right-side transmission assembly 3, a seedling feeding assembly 4, a depth-limiting soil covering device 5, a seedling-carrying and ridge-entering planting device 6, etc. One side of the first-stage transmission assembly 1 is connected to the left-side transmission assembly 2, and the other side is connected to the right-side transmission assembly 3. It matches the plant spacing requirements of the bare seedling planting agronomy through three transmission assemblies and has a specific speed ratio relationship, so as to be applicable to various cultivation modes.

[0041] In this example, the left and right orientations are set with reference to the actual running direction of the bare seedling planting device.

[0042] As Figure 3 and Figure 4As shown in the figure, the first-stage transmission assembly 1 includes a housing A1-2, and a chain transmission mechanism and a gear transmission mechanism are installed inside the housing A1-2; specifically, the chain transmission mechanism includes a chain A1-6 and sprockets A1-14 installed at both ends of the chain A1-6; one end of the housing A1-2 is installed with a shaft A1-5, and the other end is installed with a shaft C1-12. The shaft A1-5 and the shaft C1-12 are parallel to each other and both penetrate the housing A1-2; the shaft A1-5 is connected to the housing A1-2 through a bearing A1-15 installed in a bearing seat A1-1, and the shaft A1-5 and the shaft C1-12 are connected by a chain A1-6 through a sprocket A1-14.

[0043] One end of the shaft C1-12 is connected to a sprocket B1-4, and the other end is connected to a sprocket C1-11; the end of the shaft C1-12 connected to the sprocket B1-4 is connected to the right-side transmission assembly 3, and the end connected to the sprocket C1-11 is connected to the left-side transmission assembly 2.

[0044] The shaft C1-12 is connected to a servo motor 1-17 through a gear transmission mechanism. Among them, the gear transmission mechanism includes a gear A1-7 and a gear B1-10. The gear B1-10 is installed on the shaft C1-12, and the gear B1-10 meshes with the gear A1-7. The gear A1-7 is installed on a shaft B1-8, and the shaft B1-8 is connected to the servo motor 1-17; the shaft B1-8 is connected to the housing A1-2 through a bearing seat B1-16, and a bearing B1-13 is installed inside the bearing seat B1-16. Under the driving action of the servo motor 1-17, power is transmitted to the chain transmission mechanism through the gear transmission mechanism, so that the shaft A1-5 and the shaft C1-12 rotate synchronously.

[0045] A torque limiter 1-9 is installed on the shaft C1-12, and one of the sprockets A1-14 is installed outside the torque limiter 1-9; through the cooperation of the torque limiter 1-9 and the braking device configured for the whole machine, the planting device can not only be powered off at a specified position, on the one hand, ensuring the timing with the seedling feeding mechanism, and on the other hand, facilitating turning around and turning; at the same time, one-key convenient adjustment of the plant spacing is realized, improving the mechanized planting efficiency and quality.

[0046] As Figure 5 and Figure 6 As shown in the figure, the left-side transmission assembly 2 includes a housing B2-3. One end of the housing B2-3 is installed with a rotating sleeve A2-1, and the housing B2-3 can rotate around the rotating sleeve A2-1 as the rotation center. A shaft D2-2 is installed at a set position near the other end. The shaft D2-2 is parallel to the axis of the rotating sleeve A2-1, and a chain B2-6 is connected between the two; one end of the rotating sleeve A2-1 is installed with a flange, and a bearing C2-5 is installed inside this end. The bearing C2-5 is connected to the shaft C1-12. The flange is installed on one side of the housing A1-2, and the sprocket C1-11 cooperates with one end of the chain B2-6. The other end of the chain B2-6 is connected to the shaft D2-2 through a sprocket D2-8.

[0047] The shaft D2-2 is coaxially installed in the housing B2-3 through the bearing D2-7 and extends out a part. The extended end of the shaft D2-2 is an involute spline structure. An installation frame 2-4 is fixed on the outside of the housing B2-3, and the seedling-carrying and ridge-entering and transplanting device 6 is connected through the installation frame 2-4; the installation frame 2-4 is arranged on one side of the extended end of the shaft D2-2.

[0048] As Figure 7 and Figure 8 shown, the right transmission assembly 3 includes a housing C3-2. One end of the housing C3-2 is connected to the rotating sleeve B3-3 through the bearing F3-8, and the housing C3-2 can rotate around the rotating sleeve B3-3.

[0049] The rotating sleeve B3-3 is fixed to the housing A1-2 through the flange on its outside; the shaft C1-12 passes through the rotating sleeve B3-3 and is connected to it through the bearing G3-9. The sprocket B1-4 on the shaft C1-12 is connected to one end of the chain C3-4, and the other end of the chain C3-4 is connected to the shaft E3-5 through the sprocket E3-6; the axis of the shaft E3-5 is parallel to the axis of the rotating sleeve B3-3, and one end of the shaft E3-5 passes through the housing C3-2, and the other end is connected to the housing C3-2 through the bearing E3-7. One side of the housing C3-2 corresponding to the end where the shaft E3-5 is located is connected with a fixing plate A3-1, and the seedling feeding assembly 4 is installed through the fixing plate A3-1.

[0050] As Figure 9 shown, the seedling feeding assembly 4 includes a seedling feeding frame, a bare seedling feeding plate 4-1, a seedling feeding chain pair 4-10, etc. Through the seedling feeding frame, the bare seedling feeding plate 4-1 forms an isosceles trapezoid structure distribution outside the seedling feeding chain pair 4-10, and the length of the upper side of the isosceles trapezoid structure is greater than the length of the lower side, that is, an inverted isosceles trapezoid structure. One is for the need of structural design to avoid the installation frame matching the seedling feeding assembly; the other is to increase the length of the seedling feeding chain pair and the number of bare seedling feeding plates as much as possible during the structural design. Under the condition of the same planting frequency, the artificial seedling placing space is larger and it is more convenient for artificial seedling placing.

[0051] The seedling feeding frame of this embodiment is welded by profiles and is fixed to the left transmission assembly 2 and the right transmission assembly 3 respectively through bolts; sprocket groups are fixedly installed at each end of the seedling feeding frame. As Figure 12 shown, the seedling feeding frame is in a T-shaped structure, which includes two parallel cross beams A4-4-8. The two cross beams A4-4-8 are connected by longitudinal beams A4-4-2 near both ends; one end of each cross beam A4-4-8 is connected to a vertical beam A4-4-1, and the other end is connected to a vertical beam C4-4-9. The vertical beams A4-4-1 between the two cross beams A4-4-8 and the vertical beams C4-4-9 are connected by longitudinal beams B4-4-14 respectively.

[0052] There is a vertical beam D at a certain distance from the vertical beam C4-4-9. The top end of the vertical beam D is fixed to the corresponding cross beam A4-4-8, and the bottom ends of the two vertical beams C4-4-9 are also connected by a longitudinal beam B4-4-14. To ensure the connection stability, a diagonal beam C4-4-6 is installed on one side of the vertical beam C4-4-9 close to the connection end with the cross beam A4-4-8, and a longitudinal beam B4-4-14 is installed on the other side, thus forming a triangular support.

[0053] There are a vertical beam B4-4-4 and a vertical beam E4-4-13 at a certain distance from the vertical beam A4-4-1. The vertical beam B4-4-4 and the vertical beam E4-4-13 are arranged correspondingly. The top end of the vertical beam B4-4-4 is connected to the cross beam A4-4-8, and the bottom end of the vertical beam B4-4-4 is connected to the vertical beam A4-4-1 through a cross beam C4-4-11; between the connection end of the vertical beam A4-4-1 and the vertical beam B4-4-4 and the cross beam A4-4-8, it is connected by a diagonal beam A4-4-3, and on the side of the vertical beam B4-4-4 opposite to the diagonal beam A4-4-3, it is connected to the cross beam A4-4-8 by a diagonal beam B4-4-5.

[0054] There is a certain interval between the bottom end of the vertical beam B4-4-4 and the top end of the vertical beam E4-4-13. The bottom ends of the vertical beam E4-4-13 and the vertical beam B4-4-4 are connected by a cross beam D4-4-15, and between the cross beam D4-4-15 and the vertical beam A4-4-1, it is connected by a diagonal beam E4-4-16; the bottom ends of the two vertical beams E4-4-13 are connected by a longitudinal beam B4-4-14, and a mounting plate 4-4-17 for setting the right transmission assembly 3 is fixed at the top end.

[0055] As Figure 9 shown, a support sprocket group A4-3 is installed at the middle position on the outside of the cross beam A4-4-8 of the seedling feeding frame. A driven sprocket group 4-6 is installed at one end of the cross beam A4-4-8, and a tensioning sprocket group 4-11 is installed at the other end; support sprocket groups B4-9 are installed at both ends of each longitudinal beam B4-4-14. The seedling feeding chain pair 4-10 forms an inverted isosceles trapezoid structure under the support and tensioning of the support sprocket group A4-3, the support sprocket group B4-11, the driven sprocket group 4-6, and the tensioning sprocket group 4-11.

[0056] A gearbox 4-5 is installed on one of the vertical beams C4-4-9. The gearbox 4-5 is connected to the shaft E3-5; between the two vertical beams C4-4-9, a driving sprocket group 4-8 is connected. The driving sprocket group 4-8 is connected to the driven sprocket group 4-6 through a chain D4-7. The gearbox 4-5 is driven by the shaft E3-5 to transmit power to the seedling feeding chain pair 4-10 through the chain D4-7. The gearbox 4-5, the driving sprocket group 4-8, and the chain D4-7 constitute a chain drive mechanism.

[0057] As Figure 10As shown, the driven sprocket set 4-6 includes a bracket A4-6-1, a shaft F4-6-3, a sprocket F4-6-4, a sprocket H4-6-5, etc. Two sprockets F4-6-4 are installed at the middle position of the shaft F4-6-3, and the sprocket F4-6-4 is connected to the chain D4-7; sprockets H4-6-5 are installed at both ends of the shaft F4-6-3, and the sprocket H4-6-5 is connected to the seedling feeding chain pair 4-10.

[0058] A bracket A4-6-1 is provided between the sprocket F4-6-4 and the sprocket H4-6-5. One end of the bracket A4-6-1 is connected to the shaft F4-6-3 through a bearing seat C4-6-2; the other end of the bracket A4-6-1 is connected through a reinforcing beam A4-6-7; a plurality of auxiliary fastening nuts A4-6-6 are also connected to the bracket A4-6-1. The inside of the bracket A4-6-1 is a cavity. The bracket A4-6-1 is inserted into the cross beam A4-4-8 and fixed to the longitudinal beam A4-4-1 through bolts to achieve sprocket tensioning.

[0059] As Figure 11 shown, the driving sprocket set 4-8 includes a shaft G4-8-2. The shaft G4-8-2 is connected to the vertical beam 4-4-9 through a bearing seat D4-8-1. One end of the shaft G4-8-2 is connected to a connecting pipe 4-8-5 through a pin 4-8-4; two sprockets G4-8-3 are installed on the shaft G4-8-2 between the two bearing seats D4-8-1, and the sprocket G4-8-3 is connected to the chain D4-7.

[0060] As Figure 13 shown, the tensioning sprocket set 4-11 includes a bracket B4-11-3, a sprocket J4-11-5, a shaft H4-11-6, etc. Sprockets J4-11-5 are installed at both ends of the shaft H4-11-6 respectively, and the sprocket J4-11-5 is connected to the seedling feeding chain pair 4-10; the shaft H4-11-6 is connected to the bracket B4-11-3 through a bearing seat E4-11-4. There are two brackets B4-11-3 arranged in parallel to cooperate with the cross beam A4-4-8. The inside of the bracket B4-11-3 is a cavity, and it is inserted into the cross beam A4-4-8; and the two brackets B4-11-3 are connected through a reinforcing beam B4-11-2, and auxiliary fastening nuts B4-11-1 are also connected to the bracket B4-11-3.

[0061] As Figure 9 shown, a bare seedling feeding plate 4-1 is installed on each outer side formed by the seedling feeding chain pair 4-10. The bare seedling feeding plates 4-1 on each surface are equally spaced, and a flexible seedling clamping block 4-2 is installed at one end of the bare seedling feeding plate 4-1; above the running path of the seedling feeding chain pair 4-10 is the seedling placing station, and below is the seedling clamping station. The bare seedlings are placed in the flexible seedling clamping block 4-2, and the flexible seedling clamping block 4-2 and the bare seedling feeding plate 4-1 rotate with the seedling feeding chain pair 4-10, so as to convey the bare seedlings from the seedling placing station to the seedling clamping station.

[0062] The depth-limiting soil covering device 5 and the seedling-carrying and ridge-planting device 6 adopt the structures disclosed in CN111328511A, which will not be elaborated here.

[0063] The working principle of this embodiment is as follows:

[0064] When the bare-seedling planting device is operating forward normally, the torque limiter 1-9 is in a normal operating state, and the power is transmitted from the shaft A1-5 → sprocket A1-14 → chain A1-6 → torque limiter 1-9 → shaft C1-12; when the bare-seedling planting device is in a power interruption or reverse state, the torque limiter ensures idling and the power is not transmitted to the shaft C1-12.

[0065] The left transmission assembly 2 and the right transmission assembly 3 can rotate simultaneously around the fixed installation points of the first-stage transmission assembly 1. The depth-limiting soil covering device 5 is fixedly installed at the rearmost part and together with the left transmission assembly 2 and the right transmission assembly 3 forms a hinged profiling mechanism to enable the seedling-carrying and ridge-planting device 6 to profile with the undulations of the field ridges.

[0066] The power of the seedling-carrying and ridge-planting device 6 can be transmitted from the ground wheel to the shaft A1-5 through the gearbox to realize the power input of the device. At this time, the power transmission path is: ground wheel → shaft A1-5 → bearing A1-15 → chain A1-6 → shaft C1-12 → bearing B1-13 → sprocket C1-11 → chain B2-6 → sprocket D2-8 → shaft D2-2 → the crank in the seedling-carrying and ridge-planting device; or a servo motor can be installed through the reserved servo drive motor interface in the first-stage transmission assembly 1, and the servo motor is used to drive the bare-seedling clamping mechanism to act. At this time, the power transmission path is: servo motor → shaft B1-8 → gear A1-7 → gear B1-10 → shaft C1-12 → sprocket C1-11 → chain B2-6 → sprocket D2-8 → shaft D2-2 → the crank in the seedling-carrying and ridge-planting device 6. When driven by the servo motor, the power interruption and connection can be controlled by the supporting motor control system.

[0067] When the ground wheel is adopted for driving, the power transmission path of the seedling feeding chain pair 4-10 and the bare seedling feeding plate 4-1 and the flexible seedling clamping block 4-2 installed on the chain pair is as follows: shaft A1-5 → bearing A1-15 → chain A1-6 → shaft C1-12 → bearing B1-13 → sprocket B1-4 → chain C3-4 → sprocket E3-6 → shaft E3-5 → gearbox 4-5 → connecting pipe 4-8-5 → shaft G4-8-2 → sprocket G4-8-3 → chain D4-7 → sprocket F4-6-4 → shaft F4-6-3 → seedling feeding chain pair 4-10; alternatively, a servo motor can be installed through the servo drive motor interface reserved in the primary transmission assembly 1, and the servo motor is used to drive the bare seedling clamping mechanism to act. At this time, the power transmission path is: shaft B1-8 → gear A1-7 → gear B1-10 → bearing B1-13 → sprocket B1-4 → chain C3-4 → sprocket E3-6 → shaft E3-5 → gearbox 4-5 → connecting pipe 4-8-5 → shaft G4-8-2 → sprocket G4-8-3 → chain D4-7 → sprocket F4-6-4 → shaft F4-6-3 → seedling feeding chain pair 4-10.

[0068] During operation, at the seedling picking station, the bare seedlings to be planted are sequentially placed into the flexible seedling clamping block 4-2. When the bare seedlings are sequentially transported to the seedling clamping station along with the seedling feeding chain pair 4-10, the seedling carrying and ridge-inserting planting device 6 clamps and plants the bare seedlings into the soil.
