Description

Technical Field

[0001] This invention relates to the field of agricultural equipment, and more particularly to a transplanting machine and method for transplanting crops onto a dual-purpose film covering both cellars and ponds. Background Technology

[0002] Traditional methods of transplanting seedlings in pits or culverts typically involve first constructing pits or culverts, then manually placing the seedlings into them, and finally filling the pits with water. This method is very inefficient. Currently, pit construction mainly utilizes backpack pit construction machines powered by small gasoline engines. These machines use a cylindrical structure at the end of a drilling device to compress the soil and form pits. For example, CN111788900A discloses an intelligent electric-driven self-propelled tobacco pit water-filling drilling machine, including a movable base and a drilling mechanism mounted on the base. By controlling the intermittent movement of the entire machine and coordinating with the drilling mechanism, pit construction is achieved intermittently. CN114931009A discloses an intelligent double-row pit drilling and transplanting integrated device, equipment, and method. Through staggered drilling and planting mechanisms, it achieves semi-automatic transplanting of seedlings in double-row zigzag pits on large ridges.

[0003] Currently, semi-automatic transplanting machines are mainly used for pond transplanting. For example, CN105706596A discloses an automatic integrated pond transplanting device, which solves the technical problem of transplanting crop seedlings by placing an opening and closing duckbill in the pond body; CN105340439A discloses a multi-functional tracked tobacco planting management vehicle, which can be used with a duckbill transplanting device to complete the transplanting of seedlings under film and the work of pond transplanting.

[0004] Using the above methods for transplanting seedlings in pits or ponds can only achieve a single transplanting planting mode. In addition, the existing pit drilling method has very smooth pit walls, which is not conducive to seedling rooting. The existing ponds have poor soil penetration and poor soil drainage, which affects the shape of the planting pit. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a dual-purpose cellar and pond film transplanting machine and method, which can realize automatic seedling transplanting operations in both well and pond transplanting modes, while adopting a linkage hole-drilling method to improve operational efficiency.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] In a first aspect, embodiments of the present invention provide a dual-purpose cellar-pond film transplanting machine, including a cellar-pond linkage hole-drilling device, the cellar-pond linkage hole-drilling device including a transmission wheel system and a four-bar linkage planting device connected to one side of the transmission wheel system; the four-bar linkage planting device includes a four-bar linkage mechanism, a duckbill planter and a water-carrying hole driller, the duckbill planter is installed at one end of the four-bar linkage mechanism and the water-carrying hole driller is installed at the other end of the four-bar linkage mechanism to keep their trajectories consistent;

[0008] The water-carrying drilling device is either a well-cellar type or a pond-type water-carrying drilling device.

[0009] As a further implementation, the outer wall of the well-type water-carrying drill is uniformly distributed with protrusions, and the pond-type water-carrying drill adopts a spiral structure, with the blade width gradually increasing from the bottom to the top of the spiral.

[0010] As a further implementation, the transmission gear system includes a primary transmission gear set, a secondary transmission gear set, and a tertiary transmission gear set. The primary transmission gear set is connected to the power system, and the driven gear in the primary transmission gear set and the secondary transmission driving gear in the secondary transmission gear set are on the same transmission shaft.

[0011] The secondary transmission gear set includes a spur gear set and a non-spur gear set arranged in sequence. The meshing state of the spur gear set and the non-spur gear set is changed by a switching lever; the internal gears of each gear set mesh with each other.

[0012] As a further implementation, the spherical gear set includes a two-stage transmission driving spherical gear and a two-stage transmission driven spherical gear, and the non-spherical gear set includes a non-spherical gear driving wheel and a non-spherical gear driven wheel;

[0013] The secondary transmission driving spherical gear and the non-spherical gear driving wheel are mounted on the first transmission shaft, and a switching lever is provided between them. The non-spherical gear driven wheel and the secondary transmission driven spherical gear are mounted on the second transmission shaft. The switching lever is used to make the non-spherical gear driving wheel mesh with the non-spherical gear driven wheel, or to make the secondary transmission driving spherical gear mesh with the secondary transmission driven spherical gear.

[0014] As a further implementation, the four-bar linkage includes a counterweight crank, a parallel rod, and a connecting rod. One end of the parallel rod is connected to the counterweight crank, and the other end is connected to the connecting rod. One end of the connecting rod is equipped with a duckbill planter, and the other end is equipped with a water-carrying hole drill.

[0015] As a further implementation, the counterweight crank is a series of interconnected circular double cranks, each circular crank corresponding to a parallel rod, and the two parallel rods are connected to the same connecting rod.

[0016] As a further implementation, the transplanter also includes a seedling feeding device and a seedling delivery device. The seedling delivery device is installed on the upper side of the pit-connected hole-drilling device, and the seedling feeding device is located on one side of the seedling delivery device.

[0017] The cellar-connected hole-drilling device, seedling feeding device, and seedling delivery device are all installed on the frame, and the bottom of the frame is connected to a movable chassis through several leveling devices.

[0018] As a further implementation, the seedling delivery device includes a seedling tray guide device, a seedling top device, a rotating seedling transport device, and a seedling guide trough; the seedling tray guide device is located at one end of the seedling top device, and the seedling guide trough is located on one side of the seedling delivery device; the rotating seedling transport device is located below the seedling top device and is used to receive seedlings and place seedlings into the seedling guide trough.

[0019] As a further implementation, the seedling tray guiding device includes several J-shaped guide rails; the seedling lifting device includes an intermittent rotating rod, a telescopic pull rod, and a seedling lifting rod, one end of the telescopic pull rod is hinged to the intermittent rotating rod, and the other end is connected to a group of seedling lifting rods; the seedling delivery device includes seedling cups, a cup body rotating device, and a cup bottom opening device, with multiple seedling cups evenly distributed on the cup body rotating device, and the cup bottom opening device installed at the bottom of the seedling cups.

[0020] Secondly, embodiments of the present invention also provide a method for operating a transplanting machine on a dual-purpose film for cellars and ponds, including:

[0021] The seedling tray is placed into the seedling tray guide device. The seedling ejection device ejects each row of seedlings from the tray in two steps by moving laterally. After each row is completed, the seedling tray moves down one row under the action of the seedling tray guide device. Each ejected seedling lands on the rotating seedling transport device, which then rotates at a set angle to transport the seedling to the seedling guide trough and into the seedling cups. After the cup rotating device receives the seedling, it will rotate the next set of seedling cups to wait for the seedlings to be received at the seedling dispensing device.

[0022] As the seedlings in each seedling cup pass through the bottom opening device, they fall into the duckbill planter. Under the action of the four-bar planting device, the water-carrying drill first drills a hole in the front direction, and the water injection device will inject water into the hole along with the water-carrying drill. The duckbill planter then places the seedlings into the hole at the water-injected position behind it.

[0023] As a further implementation method, when the well and cellar are to be relocated, the well and cellar type water-carrying drill should be replaced in advance, and the switching lever should be used to make the non-circular gears engage, and the working speed should be set to the well and cellar relocation gear.

[0024] When transplanting seedlings into ponds, replace the water-carrying drill with a pond-type drill in advance, and use the switching lever to engage the secondary transmission spherical gear. The operating speed should be set to the pond-transplanting gear.

[0025] The beneficial effects of this invention are as follows:

[0026] (1) The water-carrying drilling device of the present invention adopts a well-cellar type water-carrying drilling device or a pond-type water-carrying drilling device, and is equipped with a transmission gear system that can change the meshing state of spur gears and non-spur gears, so that seedling transplanting in two different modes, cellar and pond, can be carried out simultaneously.

[0027] (2) The present invention achieves two-stage transmission by switching levers, using either spur gears or non-spur gears for power transmission. When the non-spur gear driving wheel and the non-spur gear driven wheel mesh, the ratio of drilling time to machine forward time is low, and the amplitude at the cycloidal overlap of the pit-pond linkage drilling device is small. The drilling device adopts a well-cellar type water-carrying drill, which can realize the vertical formation of well-cellar holes. When the two-stage transmission driving spur gear and the two-stage transmission driven spur gear mesh, the ratio of drilling time to machine forward time is high, and the amplitude at the cycloidal overlap of the pit-pond linkage drilling device is large. The drilling device adopts a pond-type water-carrying drill, which can realize the formation of pond holes.

[0028] (3) The well-type water-carrying drill of the present invention has evenly distributed protrusions, which can realize the regular concavity of the upright well wall to help the seedlings take root; the pond-type water-carrying drill adopts a spiral structure, which can achieve the effect of carrying soil out of the hole while drilling the pond.

[0029] (4) The present invention can realize automatic seedling feeding by top-out, realize fully automatic transplanting of seedlings, with low labor consumption and high efficiency; the leveling device controls the four motors under the frame to keep the overall planting components horizontal at all times, realizes the upward planting of seedlings in the middle of the ridge, which is the key to ensure the vertical growth of crops and can be applied to hilly and mountainous areas.

Detailed Implementation

[0040] Example 1:

[0041] In a typical embodiment of the present invention, such as Figure 1 As shown, a dual-purpose cellar / pond membrane transplanter is presented.

[0042] Since existing cellar and pond transplanting devices can only achieve a single transplanting mode, and the cellar walls are very smooth, which is not conducive to seedling rooting, this embodiment provides a cellar-pond dual-purpose film transplanting machine that can realize fully automatic transplanting operations of seedling hole preparation, watering, and planting in both cellar and pond transplanting modes. At the same time, the hole preparation device adopts a linkage hole preparation method to improve the operating efficiency of small intelligent machinery.

[0043] The following is a detailed description of the above-mentioned transplanting machine for both cellar and pond membrane structures, with reference to the accompanying drawings.

[0044] like Figure 1 As shown, the dual-purpose cellar-pond film transplanter includes a frame 9, a walking chassis 1, a leveling device 2, a water injection system 3, a power system 4, a control system 5, a seedling feeding device 6, a seedling delivery device 7, and a cellar-pond linkage hole-drilling device 8. The bottom of the frame 9 is connected to the walking chassis 1 through multiple leveling devices 2. The water injection system 3, power system 4, control system 5, seedling feeding device 6, seedling delivery device 7, and cellar-pond linkage hole-drilling device 8 are all installed on the upper side of the frame 9.

[0045] In this embodiment, the chassis 1 adopts a tracked walking mechanism, and two sets of tracked walking mechanisms are installed at the bottom of the frame 9. Two sets of leveling devices 2 are installed between each set of tracked walking mechanisms and the frame 9. The leveling devices 2 can extend and retract along the height direction, for example, by using hydraulic cylinders or pneumatic cylinders. The leveling devices 2 are connected to the control system 5. Through the leveling devices 2 and the control system 5, the system can adapt to different terrains, ensuring effective planting on raised beds even on uneven ground, making it suitable for hilly and mountainous areas.

[0046] It should be noted that the water injection system 3, power system 4, and control system 5 are existing technologies and will not be described in detail here.

[0047] like Figure 2 As shown, the seedling feeding device 6 includes a seedling tray guide device 6-1, a seedling top device 6-2, a rotating seedling transport device 6-3, and a seedling guide trough 6-4. The seedling tray guide device 6-1 is located at one end of the seedling top device 6-2, the seedling guide trough 6-4 is located on one side of the seedling feeding device 7, and the rotating seedling transport device 6-3 is located below the seedling top device 6-2.

[0048] The seedling-lifting device 6-2 works in conjunction with a 10*16 seedling tray, lifting out 5 seedlings at a time. After moving the tray one seedling position to the left or right, it can lift out another 5 seedlings. The rotating seedling transport device 6-3 can rotate 60° around its axis to receive seedlings and guide seedlings into the seedling tray 6-4. The rotating seedling transport device 6-3 is implemented using existing technology, which will not be described in detail here.

[0049] Specifically, the seedling tray guiding device 6-1 includes several J-shaped guide rails fixed to the frame. In this embodiment, two J-shaped guide rails are provided. During operation, the seedling tray moves downward from the head along the J-shaped path of the J-shaped guide rails and gradually retracts. The movement of the seedling tray along the J-shaped guide rails is an intermittent movement with equal intervals. When it moves to the position of the seedling top device 6-2, it is pushed out.

[0050] The seedling-lifting device 6-2 includes an intermittent rotating rod 6-2-1, a telescopic pull rod 6-2-2, and a seedling-lifting rod 6-2-3. Two telescopic pull rods 6-2-2 are provided, and the two telescopic pull rods 6-2-2 are parallel to each other. One end of each telescopic pull rod 6-2-2 is hinged to an intermittent rotating rod 6-2-1, and the other ends of the two telescopic pull rods 6-2-2 are fixedly connected to the seedling-lifting rod 6-2-3. The intermittent rotating rod 6-2-1 is connected to a power source. Under the action of the power source, the intermittent rotating rod 6-2-1 can swing at a small angle, driving the telescopic pull rod 6-2-2, on which the seedling-lifting rod 6-2-3 is installed, to move back and forth, thereby achieving seedling lifting.

[0051] The power source for the intermittent rotating rod 6-2-1 can be a motor, or a motor-driven sprocket and chain mechanism, etc. In this embodiment, five top seedling rods 6-2-3 are arranged side by side.

[0052] The seedling delivery device 7 includes seedling cups 7-1, a cup body rotating device 7-2, and a cup bottom opening device 7-3. Multiple seedling cups 7-1 are evenly distributed on the cup body rotating device 7-2, and the cup bottom opening device 7-3 is installed on the bottom of the seedling cups 7-1. The cup body rotating device 7-2 can be realized by a sprocket and chain mechanism, that is, the seedling cups 7-1 are installed on the chain, and the whole body rotates horizontally through the action of the sprocket and chain. By rotating the seedling cups 7-1 to correspond to the seedling guide groove 6-4, and in conjunction with the cup bottom opening device 7-3, the automated operation of delivering seedlings from the seedling guide groove 6-4 to the seedling cups 7-1 and then to the planting spout is realized.

[0053] The cup bottom opening device 7-3 is implemented in the following way: The seedling cup 7-1 includes a cup cylinder and a cup bottom, which are connected together by a spring and a rotating hinge. In the normal rotating position, the cup bottom is in contact with the plastic plate at the bottom and cannot be opened. When it reaches the notch position of the plastic plate, the cup bottom is unrestrained and opened, thereby realizing the opening operation of the seedling cup 7-1. The above structure is also existing technology.

[0054] The pit-and-hole-drilling device 8 is installed below the seedling delivery device 7, such as... Figures 3-5 As shown, the pit-planting device 8 includes a four-bar linkage planting device 8-1 and a transmission wheel system 8-2. The four-bar linkage planting device 8-1 is connected to the power system 4 through the transmission wheel system 8-2.

[0055] The four-bar linkage planting device 8-1 includes a mounting frame 8-1-3, a four-bar linkage mechanism, a duckbill planter 8-1-5, and a water-carrying hole drill 8-1-6. The four-bar linkage mechanism includes a counterweight crank 8-1-1, a parallel rod 8-1-2, and a connecting rod 8-1-4. The counterweight crank 8-1-1 is connected to the transmission wheel system 8-2, and is located on one side of the mounting frame 8-1-3. The transmission wheel system 8-2 is located on the other side of the mounting frame 8-1-3. The parallel rod 8-1-4... -1-2 is connected at one end to a counterweight crank 8-1-1 and at the other end to a connecting rod 8-1-4; the connecting rod 8-1-4 is horizontally positioned, with a duckbill planter 8-1-5 installed at one end and a water-carrying hole drill 8-1-6 installed at the other end, the water-carrying hole drill 8-1-6 being equipped with a water injection device 8-1-7; through the cooperation of the counterweight crank 8-1-1, the parallel rod 8-1-2 and the connecting rod 8-1-4, the duckbill planter 8-1-5 and the water-carrying hole drill 8-1-6 are aligned in trajectory.

[0056] In this embodiment, the counterweight crank 8-1-1 is a circular double crank connected together. Each circular crank corresponds to a parallel rod 8-1-2. The two parallel rods 8-1-2 are connected to the same connecting rod 8-1-4 to ensure that the trajectories of the duckbill planter 8-1-5 and the water-carrying drill 8-1-6 are strictly synchronized.

[0057] like Figure 5 As shown, the transmission gear train 8-2 includes a switching lever 8-2-4, a primary transmission gear set, a secondary transmission gear set, and a tertiary transmission gear set. The secondary transmission gear set includes a spur gear set and a non-spur gear set. Further, the primary transmission gear set includes a driving gear 8-2-1 and a driven gear 8-2-2; the spur gear set includes a secondary transmission driving spur gear 8-2-3 and a secondary transmission driven spur gear 8-2-7; the non-spur gear set includes a non-spur gear driving gear 8-2-5 and a non-spur gear driven gear 8-2-6; and the tertiary transmission gear set includes a tertiary driving spur gear 8-2-8 and a tertiary driven spur gear 8-2-9.

[0058] The driving gear 8-2-1 meshes with the driven gear 8-2-2. The driving gear 8-2-1 is driven by the power system 4. The driven gear 8-2-2 is connected to the secondary transmission driving spherical gear 8-2-3 and the non-spherical gear driving wheel 8-2-5 in sequence through the first transmission shaft. A switching lever 8-2-4 is provided between the secondary transmission driving spherical gear 8-2-3 and the non-spherical gear driving wheel 8-2-5. The secondary transmission driving spherical gear 8-2-3 and the non-spherical gear driving wheel 8-2-5 are located on the side opposite to the driven gear 8-2-2 and the counterweight crank 8-1-1.

[0059] The non-circular gear driven gear 8-2-6, the secondary transmission driven circular gear 8-2-7, and the tertiary driving circular gear 8-2-8 are mounted on the second transmission shaft, one end of which is connected to a circular crank of the counterweight crank 8-1-1. Simultaneously, the tertiary driving circular gear 8-2-8 meshes with one side of the tertiary driven circular gear 8-2-9, while the other side of the tertiary driven circular gear 8-2-9 meshes with another circular gear, which is connected to another circular crank of the counterweight crank 8-1-1. By adjusting the switching lever 8-2-4, the non-circular gear driving gear 8-2-5 can mesh with the non-circular gear driven gear 8-2-6, or the secondary transmission driving circular gear 8-2-3 can mesh with the secondary transmission driven circular gear 8-2-7, thus enabling the secondary transmission to use either circular gears or non-circular gears for power transmission.

[0060] like Figure 6 As shown, when the switching lever 8-2-4 engages the non-circular gear driving wheel 8-2-5 and the non-circular gear driven wheel 8-2-6, the ratio of drilling time to machine forward time is low, the amplitude of the cycloidal overlap of the pit-linked drilling device is small, and the drilling device adopts a well-type water-carrying drill 8-1-6-1, which can realize the vertical forming of the well-pit 8-4. Figure 7 As shown, when the switching lever 8-2-4 achieves the meshing of the secondary transmission active spherical gear 8-2-3 and the secondary transmission driven spherical gear 8-2-7, the ratio of drilling time to machine forward time is high, the amplitude of the cycloidal overlap of the pit-pond linkage drilling device is large, and the drilling device adopts the pond-type water-carrying drilling device 8-1-6-2, which can realize the formation of the pond 8-5.

[0061] In this embodiment, the main body of the well-cellar type water-carrying drill 8-1-6-1 is a metal cylindrical tube with evenly distributed protrusions on its outer wall. These protrusions create regular depressions in the upright well-cellar wall, helping seedlings to take root. The pond-hole type water-carrying drill 8-1-6-2 has a three-headed spiral structure, with the blade width gradually increasing from the bottom to the top of the spiral, giving it an overall conical shape. The pond-hole type water-carrying drill 8-1-6-2 achieves the effect of carrying soil out of the hole while drilling a pond.

[0062] This embodiment can realize automatic seedling feeding from the top, achieving fully automatic seedling transplanting with low labor consumption and high efficiency; it can also simultaneously perform seedling transplanting in two different modes, cellar and pond, making it widely applicable.

[0063] Example 2:

[0064] This embodiment provides a method for operating a transplanter on a dual-purpose film for cellars and ponds, using the transplanter described in Embodiment 1, including the following steps:

[0065] Before operation, water for transplanting seedlings is added in advance, and the power of operating components such as seedling feeding device 6, seedling delivery device 7, and pit-connected hole-drilling device 8 is cut off. At the same time, after entering the field, the walking chassis 1 should walk in the middle of the furrows on both sides of the ridge, turn on the control system 5, and adjust the frame 9 to be parallel to the ridge surface under the action of the leveling device 2 to ensure the seedling transplanting effect.

[0066] During operation, the seedling feeding device 6, seedling delivery device 7, and pit-connecting hole-drilling device 8 are connected to the power system 4 via a clutch, and the water injection system 3 is activated. After the seedling tray is placed into the seedling tray guide device 6-1, the seedling lifting device 6-2 moves left and right to lift 10 seedlings per row of the seedling tray in two stages. After each row is completed, the seedling tray moves down one row under the action of the seedling tray guide device 6-1. The 5 seedlings lifted each time will fall onto the rotating seedling transport device 6-3, which then rotates 60° to transport the seedlings to the seedling guide trough 6-4 and into the 5 seedling cups 7-1.

[0067] After the cup rotating device 7-2 receives the seedling, it will rotate the next group of 5 seedling cups 7-1 to wait for seedlings at the seedling dispensing device 6. As the seedling in each cup 7-1 passes the cup bottom opening device 7-3, it will fall into the duckbill planter 8-1-5. Under the action of the four-link planting device 8-1, the water-carrying drill 8-1-6 first drills a hole along the machine's forward direction. The water injection device 8-1-7 will then inject water into the hole along with the hollow water-carrying drill 8-1-6. The duckbill planter 8-1-5 then dispenses the seedling at the pre-drilled and watered position behind it.

[0068] When transplanting seedlings in wells or pits, at the field edge, replace the well-type water-carrying drill 8-1-6-1 in advance and use the switching lever 8-2-4 to engage the non-circular gear. The operating speed should be set to the well-cellar transplanting mode. When transplanting seedlings in ponds, at the field edge, replace the pond-type water-carrying drill 8-1-6-2 in advance and use the switching lever 82-4 to engage the secondary transmission circular gear. The operating speed should be set to the pond transplanting mode. The water injection volume for both well-cellar and pond transplanting can be set in advance by adjusting the water injection system 3 at the field edge.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
