Figure 3 As shown, the screw slide 301 is vertically positioned on the frame 1, the screw slide 301 is connected to a slide motor, the slide motor drives the screw slide 301 to move up and down, the two ground drills 302 are positioned side by side on the screw slide 301 through the bracket 303, the drill bit of each ground drill 302 is set downward, and the frame 1 is provided with a sliding sleeve for guiding the drill bit of the ground drill 302 to move up and down. When the ground drill 302 is turned on, the drill bit rotates, the slide motor drives the screw slide 301 to move up and down, and then drives the ground drill 302 to move up and down, realizing the function of digging holes in the ground.
[0029] The seeding mechanism 4 includes a seed box 401, a sprocket assembly 402 and a seed spoon 403. Figure 4 , Figure 5 As shown, the seed box 401 is funnel-shaped, and the sprocket assembly 402 includes at least two sprockets and a chain. The two sprockets are arranged up and down, one sprocket is a driving wheel, and the other is a driven wheel. The driving wheel is driven to rotate by a sprocket motor, and the chain is vertically wound around the two sprockets, and the side of the chain that moves upward passes through the inner hole of the seed box 401, and a plurality of seed spoons 403 for lifting the taro in the seed box 401 one by one are arranged circumferentially at intervals on the periphery of the chain. The high-end inlet of the inclined slide 7 is arranged near the upper part of the side of the chain that moves downward, and the taro in the seed spoon 403 can fall into the inclined slide 7 after the seed spoon 403 turns over the highest point of the chain with the chain transmission.
[0030] The flip mechanism 5 at least comprises a coverless box body 501 and a flip motor 502. Figure 6As shown, one side of the box body 501 is fixed on the rotating shaft of the flip motor 502, and the rotation of the flip motor 502 can drive the box body 501 to rotate 90° in the forward or reverse direction. The upper opening of the box body 501 is arranged near the low-end outlet of the inclined slide 7, and two rollers 503 and a flip pressing plate 504 are arranged inside the box body 501. The two rollers 503 are arranged side by side and rotate in opposite directions. When taro is supported on the two rollers 503, the two rollers 503 rotate in opposite directions to adjust the direction of the taro sprouts. The central axis of the flip motor 502 is perpendicular to the central axis of the two rollers 503. The flip pressing plate 504 is located above the two rollers 503. The flip pressing plate 504 is driven by a steering gear to flip and press the taro on the two rollers 503. A discharge port 505 for the taro to fall is provided on the side walls of the box body 501 on both sides corresponding to the two ends of the roller 503.
[0031] A visual recognition module can be set above the turning mechanism 5 to identify the orientation of the taro sprouts on the two rollers 503 through machine vision and feed it back to the control system. The control system then controls the turning motor 502 to rotate 90° forward or reversely through judgment to ensure that the taro sprouts planted later face upward.
[0032] The soil covering mechanism 6 at least comprises a fixed guide cylinder 601, a telescopic guide cylinder 602 and two duckbill pieces 603. Figure 7 , Figure 8 As shown, the fixed guide cylinder 601 is vertically positioned on the frame 1, the upper end of the fixed guide cylinder 601 is located directly below the flip mechanism 5, and the upper end of the fixed guide cylinder 601 is a trumpet-shaped structure with an outward opening, the upper end of the telescopic guide cylinder 602 extends into the lower end of the fixed guide cylinder 601 and is slidably connected to the fixed guide cylinder 601, and an electric push rod 604 for driving the telescopic guide cylinder 602 to move up and down is provided between the outer wall of the fixed guide cylinder 601 and the outer wall of the telescopic guide cylinder 602; two duckbill pieces 603 are symmetrically hinged at the lower end of the telescopic guide cylinder 602, and the two duckbill pieces 603 can be rotated to open or close by a driving mechanism, and a accommodating cavity 605 for accommodating taro is provided between the two duckbill pieces 603, and the top of the accommodating cavity 605 is connected to the lower end of the telescopic guide cylinder 602.
[0033] Furthermore, each duckbill piece 603 has hinge points on both sides of the top and the telescopic guide cylinder 602, and a gear 606 is fixed at each hinge point of the duckbill piece 603. The two gears 606 of one duckbill piece 603 correspond one-to-one and mesh with the two gears 606 of the other duckbill piece 603, so that the two duckbill pieces 603 rotate synchronously in opposite directions, and a servo 607 is provided at one of the gears 606 for driving the gear 606 to rotate.
[0034] The specific operation process is as follows:
[0035] 1. The ground drilling machine 302 starts working, the drill bit of the ground drilling machine 302 rotates, and the slide motor drives the screw slide 301 to move downward, driving the ground drilling machine 302 to move downward to realize digging a hole in the ground.
[0036] 2. Put a plurality of taro into the seed box 401, and the sprocket assembly 402 works. The chain on one side drives upward, and the chain on the other side drives downward, and the seed spoon 403 on the outer periphery of the chain also moves accordingly. Since the side of the chain that moves upward passes through the inner hole of the seed box 401, the seed spoon 403 on the chain on this side also moves upward, and during the lifting process, the taro in the seed box 401 is lifted. The volume of the batch of taro can be statistically evaluated in advance, and the seed spoon 403 of the appropriate size can be made to ensure that there is only one taro in each seed spoon 403 each time it is lifted. When the seed spoon 403 carrying the taro turns over the highest point of the chain with the chain transmission, the taro in the seed spoon 403 falls onto the inclined slide 7.
[0037] 3. After the taro slides over the inclined slide 7, it falls into the box body 501 of the turnover mechanism 5 and is supported on two rollers 503. The two rollers 503 rotate in the opposite direction to adjust the direction of the taro sprout. When the taro sprout faces either end of the roller 503, the steering gear drives the turnover pressing plate 504 to flip and compact the taro on the two rollers 503. Then, the turnover motor 502 is manually controlled to rotate 90° in the forward or reverse direction, or before the turnover pressing plate 504 does not compact the taro, the taro sprout direction on the two rollers 503 is identified by machine vision, and fed back to the control system, and the control system controls the turnover motor 502 to rotate 90° in the forward or reverse direction by judgment. At this time, the taro sprout of the taro in the turnover mechanism 5 faces upward. Then the turnover pressing plate 504 flips in the opposite direction, loosens the taro, and the taro falls out from the discharge port 505 of the side wall of the box body 501 and falls into the upper opening of the fixed guide cylinder 601 just below the turnover mechanism 5.
[0038] 4. After the taro slides through the fixed guide cylinder 601 and the telescopic guide cylinder 602 in turn, it falls into the accommodating chamber 605 between the two duckbill pieces 603 and keeps the taro sprout facing upward. Then, the electric push rod 604 works to drive the telescopic guide cylinder 602 and the two duckbill pieces 603 to move downward until the two duckbill pieces 603 extend into the holes drilled by the ground drilling machine 302. Then, the two duckbill pieces 603 open and slide the taro in the accommodating chamber 605 into the planting hole. After the taro in the accommodating chamber 605 slides out, the two duckbill pieces 603 close again, and the electric push rod 604 retracts to move the two duckbill pieces 603 out of the planting hole.
[0039] 5. After the two duckbills 603 are moved out of the planting hole, they are opened again and this time they are opened greatly. Then, the electric push rod 604 drives the telescopic guide cylinder 602 and the two duckbills 603 to move downward again. When the two opened duckbills 603 are in contact or nearly in contact with the soil at the outer opening of the planting hole, the electric push rod 604 stops moving downward, and the two duckbills 603 slowly close again, and the soil around the planting hole is scraped into the planting hole to complete the soil covering operation.
