The electrical module includes a controller with buttons and an operating lever, and the dual-axis motor is communicatively connected to the controller.

[0006] By adopting the above technical solution, the controller controls the dual-axis motor to start, thereby driving the four gear sets to rotate, and then the hole-opening mechanism, fertilizing mechanism, seedling loading mechanism, and watering mechanism start working, and the tobacco transplanting is completed through the hole-opening mechanism. The hole opener of the hole-opening mechanism is used to dig holes in the ground, which makes it convenient to control the height of the hole opener and then the depth of the hole, avoiding manual hole digging and slowing down the planting speed.

[0009] By adopting the above technical scheme, when one of the meniscus cams rotates, the arc surface of the meniscus cam first pushes the hole-opening rod to drive the hole-opening device to move toward the ground to complete the hole digging. After the arc surface of the meniscus cam no longer pushes the hole-opening rod, the hole-opening rod rebounds by the reset spring one, and then the hole-opening device is reset. The arc surface of the meniscus cam then rotates to the flap mechanism, driving the flap mechanism to rotate, thereby opening the fertilizer trough, and the fertilizer is sprinkled onto the planting ground through the discharge pipe for fertilization. Similarly, after the arc surface of the meniscus cam no longer pushes the flap mechanism, the flap mechanism is rebounded by the reset spring two, and drives it to rotate back to its original position, thereby closing the fertilizer trough outlet.

[0016] Preferably, the ends of the two output shafts of the dual-axis motor are both drivingly connected to the inside of the corresponding gear set, and the outer surface of one gear set and the outer surfaces of the other two gear sets are respectively overlapped with a belt chain 2.

[0017] By adopting the above technical solution, through three belt chains, the dual-axis motor drives the two meniscus cams to rotate, which in turn drives the hole opener to move downward to chisel the ground, the rotation of the flap mechanism and the downward movement of the duckbill, so that the fertilizer enters the chiseled hole and the tobacco seedlings are planted in the hole through the duckbill.

[0018] As the technical solution of the utility model, the hardware setting provided is only to facilitate the realization of convenient hole opening and rapid adjustment of hole opening depth on the basis of hardware facilities.

The tobacco planting machine is moving to open holes, carry seedlings, water and fertilize to complete the planting and cultivation of tobacco seedlings. The two output shafts of the dual-axis motor 6 drive the four gear sets to perform chain transmission. Among the four gear sets 5, the gears in three gear sets 5 are fixed on the same rotating shaft, and then Through the belt chain 2, the two meniscus cams 14 respectively drive the hole opener of the hole opening mechanism and the duckbill 12 of the seedling carrying mechanism to swing, and at the same time respectively drive the flap mechanism at the bottom of the fertilizer trough 10 in the fertilizing mechanism and the electromagnetic valve at the bottom of the water tank 13 in the watering mechanism to open and close, so as to release fertilizer and water to fertilize and irrigate the ground. A seat and a handle are fixedly connected to one end of the equipment frame 2 close to the electrical module. The handle adopts a brakeable handle. Pulling the brake of the handle can stop the two fixed pressure wheels 4 from rotating, so that the transplanting machine stops moving forward. The bottom of the equipment frame 2 is fixedly connected with two adjustable pressure wheels 3 and There are two fixed pressing wheels 4, and the height of the adjustable pressing wheel 3 is higher than that of the two fixed pressing wheels 4. The two adjustable pressing wheels 3 and the two fixed pressing wheels 4 are not the same in size. The two adjustable pressing wheels 3 are larger than the two fixed pressing wheels 4. The seat is located at one end close to the two fixed pressing wheels 4 and above the two fixed pressing wheels 4. By adjusting the angle between the vertical direction of the adjustable pressing wheel 3 and the horizontal direction of the bottom of the equipment frame 2, the inclination of the bottom of the equipment frame 2 to the ground can be changed, and then the distance between the hole-opening mechanism and the ground can be changed, so that holes of different depths suitable for tobacco seedlings of various varieties can be opened on the ground. The two adjustable pressing wheels 3 and the two fixed pressing wheels 4 can level the soil. Avoid the influence of road bumps and keep the hole-digging depth and transplanting depth consistent during the forward movement of the transplanter; the electrical module includes a controller with buttons and operating levers. After the driver sits on the seat, he controls the controller by pressing buttons and pulling operating levers, and then operates the transplanter to move on the surface to be planted, operates the hole-digging mechanism, fertilizing mechanism, seedling loading mechanism, and watering mechanism to work, and moves to plant tobacco. The controller can use an existing PLC processor with processing, control, judgment, and transmission functions. The dual-axis motor 6 is communicated with the controller, and the controller can control the opening and closing of the dual-axis motor 6.

[0034] Reference Figure 1 , 34. The hole-opening mechanism includes a slide rail 7, a hole-opening rod, a hole-opening device (known technology), a reset spring 9 and a bolt. The hole-opening device adopts a conical hole-opening device. The hole-opening device can instantly open and lift the hole during the operation of the transplanting machine, so that the hole remains intact and the hole-opening surface is not scratched. The top of the hole-opening rod is fixedly connected with a slider, and the slider is fixedly connected with a bearing, which is convenient for the slider to slide inside the slide rail 7, drive the hole-opening rod to move in the vertical direction, and then the hole-opening device moves up and down together, is inserted into the ground to open a hole, and then pulled out of the ground. The outer surface of the slider is slidably connected to one side of the slide rail 7, and the outer surface of the hole-opening rod is transmission-connected to the inside of the right-angle transmission device 8. The top of the right-angle transmission device 8 (known technology) is fixedly connected to the bottom of the slide rail 7, and the bottom of the hole-opening rod is fixedly connected to the top of the hole-opening device. One end of the reset spring 9 is fixedly connected to the top of the hole-opening rod. The other end of the spring 9 is fixedly connected to the top of the equipment frame 2. When the meniscus cam 14 rotates to the bearing at the top of the hole-opening mechanism, it presses down, so that the gear set 5 driven by the dual-axis motor 6 is transmitted to the hole-opening rod in the right-angle transmission device 8 through the chain, and the arc surface of the meniscus cam 14 presses the slider to slide downward inside the slide rail 7 during rotation. The reset spring 9 is in a stretched state, pressing the hole opener at the lower end to complete the hole-opening action. When the meniscus cam 14 passes the top of the hole opener, that is, the arc surface of the meniscus cam 14 no longer presses the top of the hole-opening rod, the reset spring 9 rebounds, and the top of the hole-opening rod can be pulled upward, so that the hole opener leaves the ground and resets to the inside of the equipment frame 2. The hole opener returns to its initial position and waits for the next hole-opening action; one end of one of the output shafts of the right-angle transmission device 8 is fixedly connected to the gear of one of the gear sets 5.

[0035] Reference Figure 1 , 5, wherein the other ends of the rotating shafts of the two gear sets 5 are fixedly connected with a meniscus cam 14, wherein one of the meniscus cam wheels 14 is located at the top of the slider, the fertilization mechanism comprises a fertilizer trough 10, the bottom of the fertilizer trough 10 is fixedly connected with a flap mechanism (known technology), a discharge pipe and a second reset spring, the other end of the second reset spring is fixedly connected to one side of the flap mechanism, through the transmission of the gear set 5, the seedling planting and watering process at the bottom of the fertilizer trough 10 is driven at the same time, a reset spring switch is installed in the flap mechanism at the bottom of the fertilizer trough 10, and the flip mechanism is located in the travel path of the meniscus cam 14, when the meniscus cam The wheel 14 passes through the turning mechanism and presses the turning mechanism to open the flap and let the fertilizer fall to complete the fertilization. At this time, the reset spring 2 is compressed. After the meniscus cam 14 passes, the reset spring 2 rebounds and resets to close the flap, waiting for the next time the meniscus cam 14 presses to open the turning mechanism; the motor output shaft drives the gear on the rotating shaft through the chain transmission to the other gears in the three gear sets 5, thereby driving the two meniscus cams 14 to rotate. The meniscus cam 14 rotates at a faster speed. After the hole is opened, the fertilization mechanism can instantly and accurately fertilize quickly to avoid inaccurate fertilization during the walking process of the transplanting machine.

[0036] Reference Figure 1 , 2The seedling loading mechanism includes a seedling rotating disk 11 (known technology), a connecting rod and a duckbill 12 (known technology). The seedling rotating disk 11 can change the spacing between the seedling cups to change the spacing of the transplanted tobacco seedlings. The seedling rotating disk 11 can also be changed by increasing the gear scale of the transmission gear in the seedling rotating disk 11, that is, by changing the number of teeth of the transmission gear to form a variable speed gear, so as to change the rotation speed of the seedling rotating disk 11, thereby changing the spacing of the planted tobacco seedlings. The bowl mouth of the seedling rotating disk 11 and the switch of the duckbill 12 are both electronically locked. The electronic lock is connected to the controller for communication and can be opened and closed under the processing of the controller. Another meniscus cam 14 is located between the seedling rotating disk 11 and the connecting rod. One side of the equipment frame 2 is connected to one side of the duckbill 12 through a connecting rod. The connecting rod is located below the seedling rotating disk 11. One end of the other output shaft of the right-angle transmission device 8 and the rotating shaft of the seedling rotating disk 11 are fixedly connected with a saw gear. The gear set 5 drives the connecting rod to swing, thereby driving the duckbill 12 to move up and down, and the seedlings are connected and planted. The outer surfaces of the two saw gears are overlapped with a belt chain. The several bowls of the seedling rotating disk 11 and the switch inside the duckbill 12 are communicated and connected with the controller. The switch inside the duckbill 12 adopts an electronic lock. When the controller receives the signal of the displacement sensor and judges that the duckbill 12 is at the lowest point, the duckbill 12 is opened, so that the tobacco seedlings inside the duckbill 12 fall into the dug cave; when the controller receives the signal of the displacement sensor and judges that the duckbill 12 is at the highest point, that is, the top of the duckbill 12 is close to the bottom of the bowl on the seedling rotating disk 11 but not attached, the controller controls the corresponding bowl to open, so that the tobacco seedlings in the seedling cup on the seedling rotating disk 11 fall into the duckbill 12. The duckbill 12 has a short seedling carrying time and can carry the seedlings into the cave in an instant. The duckbill 12 is quickly lifted to avoid scratching the film and scratching the ridge surface.

[0037] Reference Figure 1 , 2 3. The watering mechanism includes a water tank 13 and a water outlet pipe. The water outlet of the water tank 13 is fixedly connected with a solenoid valve (known technology). The interior of the equipment frame 2 is fixedly connected with a switch adapted to the solenoid valve. The switch is in communication with the solenoid valve. The motor output shaft drives the gear on the rotating shaft to the other gears in the three gear sets 5 through a chain transmission, thereby driving the meniscus cam 14 to rotate. One of the gears in the gear set 5 is driven by a chain to the seedling rotating disk 11 on the right-angle transmission device 8. The bowl mouth of the seedling rotating disk 11 When it rotates to above the seedling planting duckbill 12, the bottom opens to allow the seedlings to fall into the duckbill 12. A travel switch is fixed in the rotation path of the meniscus cam 14. When the cam passes and touches the switch, the solenoid valve in the water tank 13 opens, and water falls through the outlet pipe to complete the watering setting. After the meniscus cam 14 passes, the switch is no longer pressed, the switch is closed, and the solenoid valve is closed to wait for the next watering action. The meniscus cam 14 rotates faster, and the switch of the watering mechanism opens and closes faster, which can achieve instant closure and precise watering to prevent water waste.

[0038] Reference Figure 1 , 2 4. A through hole is provided at the bottom of the slide rail 7, and an adjustment hole is provided inside the equipment frame 2. The adjustment hole adopts a narrow and long straight groove. The inside of the through hole is connected to the inside of the straight groove by bolts.

The top of each adjustment screw is fixedly connected with a handwheel, and the outer surface of each hollow rod is rotatably connected The outer surface of each inner rod is fixedly connected to one side of the corresponding adjustable pressure wheel 3, and the hole opening depth of the hole opener in the ground is adjustable. The heights of the two adjustable pressure wheels 3 and the two fixed pressure wheels 4 are different. The bottom of the equipment frame 2 is in an inclined state. By slightly adjusting the position of the through hole on the hole opener on the adjustment hole on the equipment frame 2, the distance from the hole opener to the ground can be fine-tuned. By turning the handle, the sliding of the inner rod in the hollow rod is adjusted, thereby changing the angle between the equipment frame 2 and the ground, changing the distance from the hole opener to the ground, and then the major adjustment can be made through the adjustment screws on both sides of the wheel.

[0039] Reference Figure 1 , 5 The ends of the two output shafts of the dual-axis motor 6 are both connected to the inside of the corresponding gear set 5, and the outer surface of one gear set 5 and the outer surfaces of the other two gear sets 5 are respectively overlapped with belt chain 2. The two output shafts of the dual-axis motor 6 drive the rotating shafts in the four gear sets 5 to rotate through belt chain 1 and belt chain 2, thereby causing the two meniscus cams 14 to rotate, and causing the seedling rotating disk 11 to rotate.

[0040] The implementation principle of the hand-held riding tobacco seedling transplanting machine in the embodiment of the utility model is:

[0041] 1. The dual-axis motor 6 drives the two meniscus cams 14 to rotate, and then drives the hole opener of the hole opening mechanism and the duckbill 12 of the seedling loading mechanism to swing.

[0042] 2. The gear set 5 is driven to the seedling rotating disk 11 on the right-angle transmission device 8 through a chain. When the bowl of the seedling rotating disk 11 rotates to the top of the seedling planting duckbill 12, the bottom opens to let the seedling fall into the duckbill 12. At the same time, driven by the connecting rod, the duckbill 12 moves quickly to avoid the problem of dragging seedlings;
