The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0030] The following is combined with Figure 1-5 The present invention is described in further detail.

[0031] The embodiment of the present invention discloses a yam harvesting and seeding machine. Figure 1-Figure 5The yam harvesting and seeding machine includes a vehicle body 1, a power system, a furrowing device, a seeding device and a shoveling and backfilling device. The furrowing device includes a mounting frame 2 arranged at the front end of the vehicle body 1 and two furrowing devices 3 symmetrically arranged on the mounting frame 2. The power system can drive the vehicle body 1, the furrowing device, the seeding device and the shoveling and backfilling device to start and provide power for the whole vehicle. The furrowing device 3 can be driven to swing on the mounting frame 2; the seeding device includes a seed storage box 4 arranged on the vehicle body 1 for storing seeds and a transmission component 5 for sending seeds into the furrowed soil. A seeding port 11 is arranged on the bottom plate of the vehicle body 1, and the transmission component 5 sends seeds into the furrowed soil through the seeding port 11; the shoveling and backfilling device includes a seed storage box 4 arranged on the vehicle body 1 for storing seeds and a transmission component 5 for sending seeds into the furrowed soil. The shovel plates 6 on both sides are located behind the sowing port 11 on the vehicle body 1, and can be driven to realize longitudinal and lateral deflection for shoveling soil; when harvesting, the two furrow openers are located on both sides of the yam, the vehicle body 1 is started, and the furrow openers 3 dig furrows on both sides of the yam during the movement, and the soil on both sides of the yam is shoveled out, so that the yam is completely exposed to the outside, which is convenient for harvesting the yam. At the same time, the vehicle body 1 is continuously moved, and the transmission component 5 transports the yam seeds in the seed storage box 4 to the furrowed soil through the sowing port. The shovel plates 6 can move the soil to bury the yam seeds during the reciprocating movement, which significantly improves the working efficiency. The one-time operation function not only saves time and labor costs, but also makes agricultural production more convenient and efficient.

[0032] In this embodiment, the front end of the vehicle body 1 is provided with an electric motor 12 for driving the furrow opener 3 to operate and a rotating shaft 13 arranged on the output shaft of the electric motor 12. Two groups of furrow openers 3 are arranged on the rotating shaft 13 at intervals. The furrow opener 3 includes a connecting beam 31, rotating gears 32 arranged at both ends of the connecting beam 31, and a furrowing chain 33 sleeved on the two rotating gears 32. One of the rotating gears 32 is coaxially arranged on the rotating shaft 13. Two electric motors 12 are symmetrically arranged. By driving the rotating shaft 13 to rotate, the rotating gear 32 is rotated, which drives the furrowing chain to rotate, and the soil is furrowed.

[0033] In this embodiment, the trenching chain 33 is provided with a plurality of shovel blades 34 for shoveling out soil. During the trenching process, the trenching chain 33 can shovel out the soil generated by the trenching to prevent the soil generated by the trenching from re-accumulating in the opened trench and burying the trench.

[0034] In this embodiment, a turning frame 21 is swingably arranged on the mounting frame 2, and a driving cylinder 22 for driving the turning frame 21 to swing is arranged on the mounting frame 2. The swinging end of the turning frame 21 is connected to the connecting beam 31. When the yam planting depth changes, the furrowing depth needs to be adjusted. By pushing the turning frame 21 to swing by the driving lever 22, the furrow opener 3 can be swung up and down, and the furrowing depth of the furrow opener 3 can be adjusted to adapt to different yam planting depths.

[0035] In this embodiment, a fender 14 is provided at the front end of the vehicle body 1, and the motor 12 and the rotating shaft 13 are arranged in the fender 14. The fender 14 can block the mud generated during the trenching process of the trench opener 3 to prevent the mud from splashing.

[0036] In this embodiment, the conveying assembly 5 includes a conveyor belt 51 and a conveyor slide 52. The conveyor belt 51 bypasses the bottom and top of the seed storage box 4. A plurality of loading plates 53 for users to load seeds are evenly arranged on the conveyor belt 51. The side wall of the seed storage box 4 is provided with a support portion 41 for supporting the conveyor belt 51. The conveyor slide 52 is arranged on one side of the conveyor belt 51 and the conveyor belt 51 passes through the top of the conveyor slide 52. The bottom of the conveyor slide 52 is arranged on the sowing port 11. The vehicle body 1 is provided with a support beam 15 for supporting the conveyor slide 52. The conveyor belt 51 moves from the inside of the seed storage box 4 to the outside. During the movement, the conveyor belt 51 can bring out the seeds in the seed storage box 4. When it moves to the highest point and moves downward, the seeds on the conveyor belt 51 will fall on the conveyor slide 52, move to the sowing port 11 through the conveyor slide 52, and fall into the soil through the sowing port 11.

[0037] In this embodiment, the shovel backfilling device also includes a reciprocating mechanism, which includes a vertical reciprocating drive assembly 7 for driving the shovel blade 6 to move vertically and a transverse reciprocating drive assembly 8 for driving the shovel blade 6 to move horizontally. The vertical reciprocating drive assembly 7 includes a drive motor 71 arranged on the vehicle body, an output disk 72 arranged on the output shaft of the drive motor 71, and an eccentric wheel 73 arranged on the output disk 72 and eccentrically arranged with the output disk 72. The eccentric distance of the output disk 72 and the eccentric wheel 73 is adjustable, and the eccentric wheel 73 can move up and down on one side of the output disk 72. , and fixed by bolts, the eccentricity of the output disc 72 and the eccentric wheel 73 is adjusted, the shovel board 6 is eccentrically connected to the eccentric wheel 73, the drive motor 71 is started, the output disc 72 is rotated through the output shaft, and the eccentric wheel 73 rotates on the output disc 72. At the same time, an eccentricity is generated between the output disc 72 and the eccentric wheel 73. Since the shovel board 6 is eccentrically mounted on the eccentric wheel 73, the eccentric wheel 73 enables the shovel board 6 to move up and down during rotation, and then cooperates with the transverse reciprocating drive assembly 8 to enable the shovel board 6 to move vertically and horizontally, and shovel soil during the movement.

[0038] In this embodiment, a connecting block 74 is provided on the outer shell of the output shaft of the driving motor 71, and a slide rail 75 is extended downward along the connecting block 74. The earth-shoveling plate 6 is slid up and down on the slide rail 75. The eccentric wheel 73 will drive the earth-shoveling plate 6 to move during the rotation process. The earth-shoveling plate 6 is slid up and down on the slide rail 75. The slide rail 75 can limit the earth-shoveling plate 6, so that the earth-shoveling plate 6 can only move vertically along the slide rail 75, thereby preventing the earth-shoveling plate 6 from swinging left and right when moving vertically.

[0039] In this embodiment, the transverse reciprocating drive assembly 8 includes a steering gear 81 arranged in the middle position of the vehicle body 1 and two drive rods 82 arranged on the output shaft of the steering gear 81. The two drive rods 82 are eccentrically arranged, and the ends of the two drive rods 82 are hinged with rocking plates 83, and the rocking plates 83 are connected to the connecting blocks 74. The connecting blocks 74 are slidably arranged on the outer shell of the output shaft. An arc groove 16 for the movement of the drive motor 71 is opened on the vehicle body 1. The steering gear 81 is started to make the two drive rods 82 swing eccentrically through the output shaft. During the swinging process, the drive rod 82 pushes the connecting block 74, so that the connecting block 74 moves on the outer shell of the output shaft of the drive motor 71, so that the earthmoving board 6 can move laterally. At the same time, when pushing the connecting block 74 to move, the drive motor 71 can move in the arc groove 16 on the vehicle body 1 to avoid the whole mechanism from getting stuck.

[0040] In this embodiment, the outer side surface of the shovel board 6 is a hyperbolic pear shape, one side of which is used to push the yam out of the soil, and the other side is used to backfill the soil brought out.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
