Description

A self-propelled transplanter Technical Field

[0001] This utility model relates to the field of transplanting technology, and in particular to a self-propelled transplanter. Background Technology

[0002] Tobacco is a crop that is mainly cultivated by seedling transplanting. At present, the use of tobacco seedling transplanters has become one of the main methods for large-scale tobacco seedling cultivation in my country.

[0003] Currently, existing patent CN215301485U discloses a self-propelled tobacco seedling transplanting device, including a traveling vehicle, a seat, a support frame, and a gantry frame. A punching motor is mounted on the surface of the gantry frame, and a cam is connected to the output end of the punching motor. The cam contacts the upper end of an elastic element, overcoming the elastic force of the elastic element to lower the punching column for punching. This punching mechanism, including the punching motor, cam, and punching column, has the following drawbacks: because it is fixed to the gantry frame, the punching spacing cannot be flexibly adjusted according to the planting needs of different tobacco seedling varieties, different soil conditions, and different planting plans. In actual tobacco planting, different varieties of tobacco seedlings have varying requirements for growing space; some require larger spacing to ensure sufficient nutrients and light, while others can have a smaller spacing to improve land utilization. Furthermore, the soil texture and fertility vary in different regions, requiring corresponding adjustments to the punching spacing to optimize the seedling growth environment. However, the existing self-propelled tobacco seedling transplanting device with fixed hole spacing is difficult to meet diverse planting needs and has a very limited scope of application, which to some extent restricts its promotion and application in different planting scenarios.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Please refer to Figures 1-6. This utility model provides a self-propelled transplanter, including a frame 16 and a tracked walking mechanism 15 disposed at the lower end of the frame 16. A first lifting mechanism 7 is provided on the frame 16, and an outer rod 81 is provided on the first lifting mechanism 7. An inner rod 82 slides through the outer rod 81, and a drilling mechanism for drilling holes is provided on the inner rod 82. A locking part for locking the inner rod 82 is provided on the outer rod 81. The first lifting mechanism 7 is used to drive the outer rod 81 to move up and down so that the drilling mechanism can drill holes in the ridge. A seedling feeding mechanism 5 is provided on the frame 16 behind the first lifting mechanism 7. A seedling placement mechanism 6 is installed on the outer rod 81 below the seedling feeding mechanism 5. The seedling feeding mechanism 5 is used to put seedlings into the seedling placement mechanism 6, and the seedling placement mechanism 6 is used to receive the seedlings put down by the seedling feeding mechanism 5 and put the seedlings into the holes drilled by the drilling mechanism.

[0028] The locking component is a locking screw 83. The outer rod 81 has a first threaded through hole that mates with the locking screw 83, and the inner rod 82 has multiple second threaded through holes evenly distributed along its length that mate with the locking screw 83. The drilling mechanism includes a drilling motor 8 located at the end of the inner rod 82. The output shaft of the drilling motor 8 is downward-facing and has a drill bit 11 at its end. The lower end of the drill bit 11 is conical. A connecting shaft is located at the upper end of the drill bit 11, and the connecting shaft is connected to the output shaft of the drilling motor 8 via a coupling. A V-shaped auxiliary blade 10 is also provided at the lower end of the drill bit 11. The tracked walking mechanism 15 of this application can adopt a commonly used tracked chassis or the tracked walking mechanism in existing patent CN222396775U. By engaging the locking screw 83 with the first threaded through hole on the outer rod 81 and the second threaded through hole on the inner rod 82, the extension length of the inner rod 82 can be adjusted. This adjusts the distance between the drilling mechanism and the seedling feeding mechanism 6, thereby adjusting the drilling spacing.

[0029] Referring to Figures 1 and 2, the frame 16 is equipped with a second lifting mechanism, and a first lifting mechanism 7 is mounted on the second lifting mechanism. The second lifting mechanism includes a first electric push rod 9, with the push rod of the first electric push rod 9 pointing upwards and having a mounting bracket 93 at its end. Two first slide rails 92 are vertically mounted at the lower end of the mounting bracket 93. A slide seat 91 that mates with the first slide rails 92 is fixedly mounted on the frame 16. The first lifting mechanism 7 is mounted on the mounting bracket 93. The push rod of the first electric push rod 9 pushes the mounting bracket 93 to move up and down. The first slide rails 92 on the mounting bracket 93 mate with the slide seats 91 on the frame 16 to ensure stability during the lifting process.

[0030] Specifically, the first lifting mechanism 7 includes a lifting motor, which is mounted on the mounting bracket 93. The lifting motor drives the outer rod 81 to move up and down. Second slide rails 71 are respectively provided on the opposite sides of the two first slide rails 92. A slide table 72 that slides with the second slide rails 71 is provided on the outer rod 81. A connecting plate is provided on the outer rod 81, and the slide table 72 is mounted on the connecting plate. The lifting motor can be the lifting motor described in existing patent CN 222548014 U. Alternatively, the lifting motor can be an existing screw jack, and the outer rod 81 can be located at the lower end of the screw of the screw jack. The input end of the screw jack is also connected to a drive motor.

[0031] More specifically, the seedling feeding mechanism 6 includes a seedling feeding frame 61, a seedling feeding tube 62 disposed within the seedling feeding frame 61, and a seedling receiving hopper 63 disposed at the upper end of the seedling feeding tube 62. Two seedling feeding spouts 4 are symmetrically hinged at the lower end of the seedling feeding tube 62. A second electric push rod 66 is mounted on the seedling feeding frame 61, and a hinge post is mounted on each seedling feeding spout 4. The push rod end of the second electric push rod 66 is hinged to the hinge post via a connecting rod 65. A reset post is mounted on each seedling feeding spout 4 opposite to the hinge post, and a reset spring 64 is disposed between the two reset posts. The seedling receiving hopper 63 receives the seedlings fed by the seedling feeding mechanism 5 and transports them to the seedling feeding spouts 4 through the seedling feeding tube 62. The second electric push rod 66 controls the opening and closing of the seedling feeding spouts 4, and the reset spring 64 ensures that the seedling feeding spouts 4 quickly reset after the seedlings are fed.

[0032] As shown in Figures 1 and 4-6, the seedling delivery mechanism 5 includes a seedling cup conveyor chain 52 and a seedling delivery motor 51 for driving the seedling cup conveyor chain 52. Multiple seedling cups 53 are spaced apart along the circumference of the outer side of the seedling cup conveyor chain 52. There are two seedling cup conveyor chains 52, namely an upper annular conveyor chain and a lower annular conveyor chain. The seedling cup conveyor chain 52 is a ring-shaped chain. Two driven shafts 521 are rotatably mounted on the frame 16. Drive sprockets that cooperate with the seedling cup conveyor chain 52 are mounted on the driven shafts 521. A driven sprocket is also mounted on the driven shafts 521. The output shaft end of the seedling feeding motor 51 is equipped with a drive sprocket. The drive sprocket and the driven sprocket are connected by a power transmission chain 511, which is a ring-shaped chain. The seedling cup 53 is provided with a first fixed post and a second fixed post spaced apart in the vertical direction. The first fixed post is welded to the lower end of the link of the upper ring conveyor chain. An L-shaped plate is fixed on the second fixed post. The L-shaped plate includes a vertical part and a horizontal part connected to the vertical part. The horizontal part is welded to the lower end of the link of the lower ring conveyor chain.

[0033] The seedling cup 53 has a seedling inlet at its lower end, and a seedling baffle 531 is hinged to the inlet. The lower end of the seedling cup 53 has an annular baffle 54 that contacts the baffle 531 to block the seedling inlet. The annular baffle 54 has a seedling drop opening 541 located directly above the seedling hopper 63. When the seedling cup 53 passes through the drop opening 541, the baffle 531 opens due to its own weight, allowing the seedling to fall into the seedling hopper 63. It should be noted that any parts not detailed in this application are prior art.

[0034] In addition, a water tank 12 is provided on the frame 16. The water tank 12 is connected to a connecting pipe via a water pump. A watering pipe 14 for pouring water into the holes drilled by the drilling mechanism is connected to the connecting pipe. A water control solenoid valve 13 is provided on the watering pipe 14. Water can be poured into the drilled holes by controlling the water control solenoid valve 13.

[0035] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0036] For example, in other embodiments, different from the embodiments described above, as shown in Figure 1, an electrical control box is also provided on the frame 16. A seat is provided on the frame 16 at the rear end of the seedling feeding mechanism 5. The electrical control box contains a PLC controller, which is electrically connected to the drilling motor 8, the first electric push rod 9, the lifting motor, the second electric push rod 66, the seedling feeding motor 51, the water control solenoid valve, and the crawler walking mechanism 15. A battery 1 is also provided on the frame 16, which is electrically connected to the PLC controller, the drilling motor 8, the first electric push rod 9, the lifting motor, the second electric push rod 66, the seedling feeding motor 51, the water control solenoid valve, and the crawler walking mechanism 15.

[0037] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0038] The annular baffle plate 54 has two opposing ends located at the seedling inlet 541. One end has a downwardly inclined plate extending downwards from the plane of the annular baffle plate 54, with an angle of 150 degrees between the inclined plate and the annular baffle plate 54. After the seedling cup 53 is filled with seedlings, it continues to move along the conveying direction. The baffle plate 531 contacts the inclined plate 542. As the seedling cup 53 moves along the conveying direction, the baffle plate 531 gradually blocks the seedling inlet until it moves to the point where it completely blocks the seedling inlet by contacting the upper surface of the annular baffle plate 54.

[0039] The working principle of this application is as follows: Before the self-propelled transplanter enters the field, the distance between the drill bit 11 and the seedling release nozzle 4 is adjusted to obtain the required plant spacing. The distance between the drill bit 11 and the seedling release nozzle 4 is adjusted by adjusting the extension length of the inner rod 82. After the adjustment is completed, it is locked by the locking screw 83.

[0040] The tracked walking mechanism 15 is activated, moving the transplanter to the transplanting area. The operator places the tobacco seedlings into the seedling delivery cup 53. The seedling delivery motor 51 drives the seedling cup conveyor chain 52. When the seedling delivery cup 53 reaches the seedling drop opening 521, the seedling baffle 531 opens, and the seedling falls into the seedling receiving hopper 63. The seedling then passes through the seedling feeding pipe 62 to the seedling release nozzle 4. Simultaneously, the drilling mechanism and the seedling delivery mechanism 5 are lowered together under the control of the first lifting mechanism 7. The front drilling motor 8 drives the drill bit 11 to rotate and drill holes, while the rear second electric push rod 66 actuates, opening the seedling release nozzle 4 and placing the seedling into the hole. Water is then added to the hole via the control water control solenoid valve 13. After the operation is complete, the control water control solenoid valve 13 is shut off, and the first lifting mechanism 7 drives the drilling mechanism and the seedling delivery mechanism 5 to rise.

[0041] In addition, when the transplanter enters the field and makes the first hole, there is no seedling in the seedling feeding cup 4. That is, when the seedling is initially fed into the seedling feeding cup 53, one of the seedling feeding cups 53 is left empty. After making the first hole, the above actions can be repeated. The transplanter continues to make holes, feed seedlings, place seedlings and water. After completing the work in the entire transplanting area, the equipment is turned off.

[0042] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
