The cover of the transplanting cylinder is inclined toward downward, and the opening and closing driving member is movably arranged on the transplanting cylinder in the vertical direction. The two ends of the bent rod are respectively fixed on the transplanting cylinder cover, and are hinged on the opening and closing driving member. When the seedling-replenishing cylinder contains seedlings and the seedling-replenishing turntable rotates, the seedling-replenishing cylinder rotates relative to the seedling-replenishing bottom plate, and the lower cover of the drop cylinder remains closed due to being blocked by the seedling-replenishing bottom plate, so that the seedlings are in the seedling-replenishing cylinder. When a seedling-replenishing cylinder corresponds to the seedling-replenishing through hole, the lower cover of the drop cylinder is opened because it is not blocked by the seedling-replenishing bottom plate, so that the lower mouth of the seedling-replenishing cylinder opens correspondingly to the transplanting cylinder, and then the seedlings fall from the seedling-replenishing cylinder into the transplanting cylinder, and the transplanting cylinder completes the transplanting process of the seedlings by moving to the predetermined ground and opening the transplanting cylinder cover. Therefore, the seedling transfer of the utility model is completely realized by free fall rather than mechanical restraint, which avoids mechanical damage to the seedlings and ensures the high-quality cultivation of subsequent crops.

[0017] 2. Because the number of transplanting tube covers and bent rods of the utility model are multiple and the same, the multiple transplanting tube covers are closed at the bottom of the transplanting tube to form a conical closed cover, and the cone tip is vertically facing downward. Therefore, the utility model pierces the predetermined ground with the cone tip and opens the multiple transplanting tube covers to transplant the seedlings into the predetermined ground, thereby completing the transplanting process.

[0018] 3. Because the fuselage of the utility model also includes a fuselage frame and a seedling receiving assembly, the seedling replenishment bottom plate is fixedly mounted on the fuselage frame, the seedling receiving assembly includes a vertically arranged seedling guide tube, a pull-out partition curtain, a winding volute spring and a pull-back motor, the seedling guide tube is hollow and has openings at both ends, and is vertically fixed inside the fuselage frame, the number of seedling guide tubes is multiple and the multiple seedling guide tubes correspond one by one to the multiple seedling replenishment tubes, the winding volute spring and the pull-back motor are respectively fixedly mounted on opposite sides of the fuselage frame, and are located between the seedling guide tube and the seedling replenishment tube in the vertical direction, one end of the pull-out partition curtain is connected and wound on the output shaft of the pull-back motor through a rope, and the other end is fixedly mounted on the free end of the winding volute spring, and when the pull-back motor rotates forward, the winding volute spring is overcome to pull the seedling replenishment tube through the traction rope The rewinding force of the partition curtain will unfold the pull-out partition curtain, so that the pull-out partition curtain forms a barrier between the seedling guide tube and the seedling supplement drop tube. At this time, the seedlings are placed in the seedling guide tube, and the seedlings are accommodated in the space formed by the seedling guide tube and the pull-out partition curtain; when the rewinding motor reverses, the winding spiral spring converges the pull-out partition curtain to the end of the fuselage base frame through the rewinding force, thereby blocking the contact between the seedling guide tube and the seedling supplement drop tube. At this time, the seedlings fall from the seedling guide tube into the seedling supplement drop tube, preparing for the subsequent transplanting process. Therefore, the use of the new type can realize one or more automatic seedling supplements, and in the process of automatic seedling supplements, there is no risk of mechanical pinching of the seedlings, so there is no need to rely on manual seedling supplement preparations every time, thereby improving the work efficiency of transplanting.

[0019] 4. Because the chassis unit of the utility model also includes a second drive motor, two steering links, a steering hinge rod, a linkage rod and a steering wheel, the second drive motor is fixedly mounted on the chassis frame, the steering hinge rod is fixedly connected to the steering wheel correspondingly, one end of the steering hinge rod is hinged on the chassis frame, and the two steering hinge rods are connected by a linkage rod to form a linkage structure, the two steering links are composed of two hinged rods, one end of the two steering links is fixedly mounted on the output shaft of the second drive motor to form a crank structure, and the other end is hinged on the steering hinge rod, and the other end, the linkage rod and the steering hinge rod are at different hinge axis distances on the chassis. When the second drive motor rotates, a rod crank of the two steering links rotates, and the other rod pushes the steering hinge rod to rotate, and the steering wheel is fixed on the steering hinge rod, that is, the steering hinge rod drives the steering wheel to rotate by rotating, thereby causing the steering wheel to change its forward direction. Therefore, the utility model uses a simple crank-connecting rod mechanism to steer the steering wheel, that is, the utility model steers.

[0038] The fuselage frame 11 is fixed on the chassis frame 21 of the chassis unit 20. Specifically, the fuselage frame 11 is a vertically arranged aluminum alloy frame structure, and the seedling receiving assembly 12, the seedling supplement assembly 13, and the transplanting assembly 14 are sequentially stacked from top to bottom inside the fuselage frame 11.

[0039] like Figure 3 and Figure 4As shown, the seedling containing assembly 12 includes a seedling guiding turntable 121, a seedling guiding tube 122, a pull-out curtain 123, a gathering and rolling box body 124, a pull-back motor 125 and a traction rope 126. Specifically, the gathering and rolling box body 124 and the pull-back motor 125 are at the same vertical position on the fuselage base frame 11, and the seedling guiding turntable 121 is arranged above the gathering and rolling box body 124 and the pull-back motor 125. Specifically, the seedling guiding turntable 121 is fixed to the fuselage base frame 11 by bolts. In this embodiment, the number of seedling containing assemblies 12 is two, which are adjacently arranged in the vertical direction.

[0040] There are multiple seedling guide tubes 122, and the multiple seedling guide tubes 122 are arranged in a circle along the circumference of the seedling guide turntable 121.

[0041] The seedling guide tube 122 is vertically passed through and arranged on the seedling guide turntable 121. The seedling guide tube 122 is hollow and has openings at both ends. Specifically, the seedling guide turntable 121 has a plurality of through holes (not shown in the drawings) corresponding to the seedling guide tube 122. The seedling guide tube 122 passes through the through holes accordingly, and the seedling guide tube 122 is connected and fixed to the seedling guide turntable 121 through a flange structure provided in the middle of its own length.

[0042] A winding coil spring (not shown in the accompanying drawings) is arranged inside the winding box body 124, and the winding box body 124 and the pulling-back motor 125 are respectively fixed on opposite sides of the fuselage base frame 11, and one end of the pull-out partition curtain 123 is connected and wound on the output shaft of the pulling-back motor 125 through a traction rope 126, and the other end is inserted into the winding box body 124 and fixed on the free end of the winding coil spring. Specifically, the overall structure of the winding box body 124 and the pull-out partition curtain 123 is a product that is easily purchased on the market (Taobao product name: refrigerator pull curtain anti-mosquito transparent roller curtain, Shuncheng kitchen accessories).

[0043] like Figure 5 and Figure 6 As shown, the seedling supplement component 13 includes a seedling supplement bottom plate 131, a seedling supplement steering gear (not shown in the drawings), a seedling supplement turntable 132 and a seedling supplement drop tube 133.

[0044] The seedling replenishment bottom plate 131 is horizontally fixed on the fuselage base frame 11, and a seedling replenishment through hole 1311 is formed on the surface.

[0045] The seedling supplement steering gear is fixed on the upper end surface of the seedling supplement bottom plate 131 and the output shaft is vertically upward. The seedling supplement turntable 132 is horizontally arranged on the output shaft of the seedling supplement steering gear. The number of seedling supplement drop cylinders 133 is multiple, which are vertically arranged and arranged on the seedling supplement turntable 132 in a rotationally symmetrical manner with the rotation axis of the seedling supplement turntable 132. Specifically, the seedling supplement turntable 132 corresponds to the seedling guide turntable 121 in the vertical direction, and the multiple seedling guide cylinders 122 correspond to the multiple seedling supplement drop cylinders 133 one by one and are coaxial, that is, a seedling container component 1 2, the pull-out partition curtain 123 is located between the seedling guiding tube 122 and the seedling supplementing tube 133 in the vertical direction, so that when the pull-out partition curtain 123 is stretched by the pull-back motor 125, the pull-out partition curtain 123 forms a barrier between the seedling guiding tube 122 and the seedling supplementing tube 133; when the pull-out partition curtain 123 is restored and converged into the winding box body 124, the barrier formed by the pull-out partition curtain 123 between the seedling guiding tube 122 and the seedling supplementing tube 133 is released, and the seedling guiding tube 122 and the seedling supplementing tube 133 are opened relatively.

[0046] The seedling-replenishing drop tube 133 is hollow and has an open upper end, and is hingedly provided with an openable and closable drop tube lower cover 1331 at the lower end, and a gap between the lowest part of the drop tube lower cover 1331 and the seedling-replenishing bottom plate 131 is smaller than a predetermined distance. Specifically, the predetermined distance is extremely small, so that when the seedling-replenishing bottom plate 131 blocks the drop tube lower cover 1331, the lower end of the seedling-replenishing drop tube 133 is closed by the drop tube lower cover 1331.

[0047] The plane where the bottom end surface of the seedling drop cylinder 133 is located is inclined downward, and the closed drop cylinder lower cover 1331 is a flat plate inclined downward, the seedling through hole 1311 corresponds to the size of the lower opening of the seedling drop cylinder 133, the center of the seedling through hole 1311, the extension axis of the seedling drop cylinder 133 and the rotation axis of the seedling turntable 132 are all at the same distance, so that the seedling turntable 132 rotates to make a single seedling drop cylinder 133 correspond to the seedling through hole 1311, and during the rotation process, specifically, the bottom of the seedling drop cylinder 133 forms a wedge shape, and the side of the drop cylinder lower cover 1331 hinged to the seedling drop cylinder 133 is far away from the seedling bottom plate 131, and when the seedling turntable 132 rotates, the side closer to the seedling bottom plate 131 passes through the seedling through hole 1311 relative to the hinged side.

[0048] Specifically, the seedling supplement drop tube 133 passes through the seedling supplement turntable 132 in the same manner as the seedling guide tube 122 .

[0049] like Figure 7 and Figure 8 As shown, the transplanting assembly 14 includes a lifting base 141, a lifting motor 142, a driving screw (not shown in the figure), a lifting slider 143, a transplanting cylinder 144, a second driving servo 145, two driving connecting rods 146, an opening and closing driving member 147 and a bending rod 148.

[0050] The lifting base 141 is fixed on the chassis frame 21 of the chassis unit 20 , and a lifting convex rail (not shown in the drawings) extending vertically is formed on the lifting base 141 .

[0051] The lifting motor 142 is fixed on the lifting base 141 and has an output shaft extending vertically downward. The driving screw is coaxially fixed on the output shaft of the lifting motor 142. The lifting slider 143 is arranged on the lifting convex rail through a groove structure. The transplanting tube 144 is arranged on the lifting slider 143 in the vertical direction. The lifting motor 142 drives the lifting slider 143 to rotate and drive the transplanting tube 144 to lift and lower in the vertical direction.

[0052] The top of the transplanting tube 144 is open and corresponds to the seedling through hole 1311 in the vertical direction, and the transplanting tube 144 and the seedling dropping tube 133 are separated by the seedling bottom plate 131. The bottom of the transplanting tube 144 is hinged with a transplanting tube cover 1441 that can be opened and closed. In this embodiment, the top of the transplanting tube 144 forms a receiving trumpet mouth portion 144a.

[0053] The second driving servo 145 , the opening and closing driving member 147 and the bending rod 148 are sequentially arranged on the transplanting tube 144 from top to bottom, and the bending rod 148 is located near the lower end of the transplanting tube 144 .

[0054] The number of the second driving steering gear 145 and the number of the driving two connecting rods 146 are both two and they are connected correspondingly.

[0055] The driving two connecting rods 146 are composed of two rods hinged at the ends. One end of the driving two connecting rods 146 is fixed on the output shaft of the second driving servo 145, and the other end is hinged on the opening and closing driving member 147. Therefore, when the second driving servo 145 rotates, the opening and closing driving member 147 is lifted and lowered in the vertical direction by driving the two connecting rods 146.

[0056] Specifically, the opening and closing driving member 147 is a sleeve that is cooperatively sleeved outside the circumference of the transplanting tube 144 .

[0057] There are multiple and identical numbers of transplanting tube covers 1441 and bending rods 148. Multiple transplanting tube covers 1441 are closed at the bottom of the transplanting tube 144 to form a conical closed cover, and the cone tip is vertically facing downward. The opening and closing drive member 147 is movably arranged on the transplanting tube along the vertical direction. One end of the bending rod 148 is fixed on the transplanting tube cover 1441, and the other end is hinged on the opening and closing drive member 147, so that when the opening and closing drive member 147 rises, the multiple transplanting tube covers 1441 open in a petal shape, that is, the lower end of the transplanting tube 144 is open to the outside; when the opening and closing drive member 147 descends, the multiple transplanting tube covers 1441 are closed in a petal shape, that is, the lower end of the transplanting tube 144 is closed relative to the outside.

[0058] The watering unit 15 and the tilling unit 16 are both detachably arranged on the chassis frame 21 of the chassis unit 20 by means of pin connection, and the leveling unit 17 is fixedly arranged on the chassis frame 21 .

[0059] The watering unit 15 includes a watering container 151 and a watering member (not shown in the drawings). The mouth of the watering member faces the predetermined ground and is used to spray water on the predetermined ground. Specifically, the watering member is located at the rear of the vehicle.

[0060] like Fig. 9 As shown, the plowing unit 16 includes a plowing motor (not shown in the drawings), a plowing bracket 161 and a plowing ratchet 162. The plowing ratchet 162 has plowing ratchet teeth (not shown in the drawings) inserted into a predetermined ground. The plowing motor drives the plowing ratchet 162 to rotate. Specifically, the plowing ratchet 162 is located in front of the front of the vehicle. In the present embodiment, the number of the plowing ratchet 162 is four.

[0061] like Fig.10 As shown, the leveling unit 17 includes a leveling motor (not shown in the drawings), a leveling bracket 171 and a pair of leveling wheels 172. The pair of leveling wheels 172 are mirror-symmetrical, facing the predetermined ground and inclined toward each other. Specifically, the pair of leveling wheels 172 are both located at the rear of the vehicle.

[0062] like Fig.11 and Fig.12 As shown, the chassis unit 20 is disposed at the bottom of the fuselage portion 10 , and the chassis unit 20 is used to drive the fuselage portion 10 to move on a predetermined ground.

[0063] The chassis unit 20 includes a chassis frame 21, namely, a driving wheel 22, a first driving motor 23, a steering wheel 24, a steering hinge 25, a linkage rod 26, two steering links 27 and a second driving motor 28, all of which are arranged on the chassis frame 21. In this embodiment, the utility model adopts a deep-grooved agricultural wheel.

[0064] The number of the driving wheels 22 and the number of the steering wheels 24 are both a pair.

[0065] There are two first drive motors 22 , which directly drive two drive wheels 22 to rotate respectively.

[0066] There is one second drive motor 28, and there is a pair of steering hinges 25, which are fixedly connected to the two steering wheels 24. One end of the steering hinge 25 is hinged on the chassis frame 21, and the two steering hinges 25 are connected by a linkage rod 26 to form a linkage structure. Specifically, the two ends of the linkage rod 26 are respectively hinged to different steering hinges 25.

[0067] There is one steering link 27, which consists of two hinged rods. One end of the steering link 27 is fixed on the output shaft of the second drive motor 28 to form a crank structure, and the other end of the steering link 27 is hinged on a steering hinge 25, and the hinge axis distances between the other end, the linkage rod 26 and the steering hinge 25 on the chassis frame 21 are not equal, that is, in the motion system formed by the rotation of the steering hinge 25, the hinge point formed by the steering link 27 on the steering hinge 25 and the hinge point formed by the linkage rod 26 on the steering hinge 25 have different force arms respectively.

[0068] The specific working process of the automatic transplanting and seedling-replenishing machine 100 is described below in conjunction with the embodiment:

[0069] First, the seedlings to be transplanted are placed in the seedling guide tubes 122 of the seedling container assembly 12 respectively.

[0070] Then, while the automatic transplanting and seedling-filling machine 100 is traveling on the field, the plowing ratchet 162 in front of the vehicle rotates to plow the field; the watering piece at the rear of the vehicle sprinkles water onto the field through the mouth; and the leveling pair of wheels 172 at the rear of the vehicle continuously rotates to level the field by tilting downward.

[0071] Then, the pull-out partition curtain 123 closest to the seedling supplement component 13 is first retracted into the interior of the retracting box body 124 , and the seedlings to be transplanted fall freely from the seedling guide tube 122 into the interior of the seedling supplement drop tube 133 .

[0072] Then, the seedling rotation disk 132 rotates at a predetermined speed, and when the seedling drop cylinder 133 corresponds to the seedling through hole 1311 , the drop cylinder lower cover 1331 opens, and the seedlings to be transplanted fall freely from the seedling drop cylinder 133 through the seedling through hole 1311 to the inside of the transplant cylinder 144 .
