[0022] A precision sowing device for experimental corn seeds, such as Figure 1-6As shown, it includes a frame 1, a corn hopper 2, a tillage wheel 3, a feed hopper 4, an electric control valve 5, a discharge pipe 6, a seed box 7, a back plate 71, a discharge channel 72, a vibrator 73, a lifting cylinder 8, a lifting rod 81, a feed trough 82, a movable baffle 9, a connecting piece 10, an electric control telescopic cylinder 11, a slide rod 12, a guide rail block 13, a discharge port 14, a pin 15 and a duckbill soil dividing bucket 16, wherein two feed hoppers 4, two electric control valves 5 and two discharge pipes 6 are provided, and the top of the frame 1 is connected to a corn hopper 2 for discharging vertically downward, and the two feed hoppers 4 are connected to the top of the frame 1. The two feed hoppers 4 are arranged in an array on the right side of the corn hopper 2. The feed hopper 4 close to the corn hopper 2 is used to fill in fertilizer, and the feed hopper 4 away from the corn hopper 2 is used to fill in water. The bottom is embedded with an electric control valve 5, and the bottom of the electric control valve 5 is connected to a discharge pipe 6. The two feed hoppers 4 and the two discharge pipes 6 are made of high-strength and corrosion-resistant polyvinyl chloride plastic. The bottom of the frame 1 is connected to four tillage wheels 3, and the four tillage wheels 3 are arranged in a central symmetrical manner on the horizontal plane. Each tillage wheel 3 is located at the four vertices of a square. The tillage wheels 3 are all electric wheels. The bottom end of the corn hopper 2 is connected to a circular seed box 7, and the rear side of the seed box 7 is connected to a circular back plate 71. The discharge channel 72 is embedded in the seed box 7 and is also annular. The vibration module of the vibrator 73 is tightly attached to the front side of the back plate 71. The vibrator 73 uses a high-frequency and low-intensity vibration method to make the seeds looser in the discharge channel and not easily damaged by vibration. The front side of the back plate 71 is also connected It is connected to a lifting cylinder 8 that can only move vertically up and down. The piston rod of the lifting cylinder 8 is vertically connected to the lifting rod 81. The lifting rod 81 is slidably connected to the lower part of the seed box 7. The lifting rod 81 completely penetrates the discharge channel 72 during the sliding process. A feed trough 82 is provided at the lower part of the lifting rod 81. When the lifting cylinder 8 contracts, the feed trough 82 and the discharge channel 72 inside the seed box 7 form a smooth path. A discharge port 14 is provided at the bottom of the lifting rod 81. The discharge port 14 is connected to the feed trough 82. Two electrically controlled telescopic cylinders 11 with opposite moving directions are provided on the left and right sides of the lower part of the lifting rod 81. Two movable baffles 9 are slidably connected on the front and back sides of the bottom of the lifting rod 81. The movable baffle 9 is used to block the connecting part between the feed trough 82 and the discharge port 14. The two movable baffles The bottom ends of the plates 9 are connected to a corner away from each other, and the telescopic rods of the two electric telescopic cylinders 11 are respectively connected to the two connecting parts 10. When the electric telescopic cylinder 11 slides, the connecting part 10 drives the movable baffle 9 to move in the direction away from the lifting rod 81. The end of the connecting part 10 away from the movable baffle 9 is connected to a cylindrical slide bar 12. The front and rear sides of the bottom end of the lifting rod 81 are rotatably connected to the pin shaft 15. The top of the pin shaft 15 is connected to a guide rail block 13 slidably connected to the slide bar 12. The two guide rail blocks are both vertically arranged in the initial state. The two guide rail blocks 13 can only rotate in opposite directions when the two electric telescopic cylinders 11 move horizontally. A duckbill soil bucket 16 is connected to the pin shaft 15. The rotation of the guide rail block 13 drives the duckbill soil bucket 16 to rotate.The duckbill soil bucket 16 is made of stainless steel that is resistant to soil pollution.
[0023] When a farmer needs to use the present invention to cultivate corn, he places the present invention in the corn field to be cultivated, and the tillage wheels 3 connected to the bottom of the frame 1 sink into the cultivated field to stabilize the frame 1. Then the farmer puts the corn seeds to be cultivated into the corn hopper 2. At this time, the corn seeds will flow into the discharge channel 72 built into the seed box 7 along the lower end of the corn hopper 2. After that, the farmer starts the present invention, and the present invention will slowly move forward in the cultivated field through the uniform rotation of the tillage wheels 3. The farmer only needs to control the direction of the frame 1 and the switch of the present invention.
[0024] After the present invention is started, the four tillage wheels 3 rotate to drive the present invention as a whole to move forward, and then the lifting cylinder 8 is started, and the lifting cylinder 8 quickly moves the lifting rod 81 downward. At this time, the feeding chute 82 in the lifting rod 81 is connected with the feeding channel 72, and the feeding chute 82 is already filled with sufficient corn seeds. The lifting rod 81 will move downward together with the corn seeds through the feeding chute 82. At the same time, the upper main body of the lifting rod 81 will block the place where the feeding channel 72 is originally connected to the feeding chute 82, ensuring that the corn seeds in the feeding channel 72 will not leak out. Then the duckbill openings formed by the two duckbill soil buckets 16 break the soil layer, and the lifting rod 81 is inserted into the soil. The two electrically controlled telescopic cylinders 11 are also started and will move quickly at the same time. The electrically controlled telescopic cylinder 11 pushes the two connecting parts 10 to move horizontally, and the two movable baffles 9 connected to one end of the two connecting parts 10 will be quickly pulled out of the lifting rod 81 under the push, and the corn seeds originally blocked in the feeding chute 82 by the movable baffle 9 will pass through the discharge port 14. At the same time, due to the horizontal movement of the connecting piece 10, the slide bar 12 at the other end of the connecting piece 10 will also move, and the guide block 13 set on the slide bar 12 will swing due to the horizontal movement of the slide bar 12. The pin 15 will rotate due to the swing of the guide block 13, and the duckbill soil bucket 16 will also rotate together due to the rotation of the pin 15. The two duckbill soil buckets 16 rotate in opposite directions to form an open duckbill mouth. At this time, since the soil is pushed forward by the duckbill soil bucket 16, When the two sides are pushed apart, the corn seeds can smoothly leak into the soil. At this time, the lifting cylinder 8 and the electronically controlled telescopic cylinder 11 are controlled to return to their initial states, and the duckbill soil bucket 16 and the movable baffle 9 are driven to close in the direction of the lifting rod 81. The lifting rod 81 is also pulled back to its initial position by the lifting cylinder 8, and the feed chute 82 is connected to the discharge channel 72 again. A new batch of corn seeds will also leak into the feed chute 82. At this time, one corn seed sowing is completed. Repeating the above operation can achieve continuous corn seed sowing.
[0025] The addition of the feed hopper 4, the electric control valve 5 and the discharge pipe 6 allows the seeder to perform the operations of sowing, fertilizing and watering at the same time. Farmers can add fertilizer and water to the two feed hoppers 4 in sequence. After the utility model completes the sowing of corn seeds once, before moving to the next corn seed sowing point, the electric control valve 5 is opened. When passing the point just sown, fertilizer and water are applied therein in sequence to help the growth of the corn seeds. The vibrator 73 connected to the back plate 71 can be started when the lifting rod 81 is fully reset after each corn seed sowing. At this time, the corn seeds in the discharge channel 72 will become loose due to the vibration of the vibrator 73, so that the corn seeds can continue to leak into the feed trough 82, avoiding blockage caused by the accumulation of corn seeds.
[0026] The above description is merely an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
