Description

Technical Field

[0001] This utility model belongs to the field of wheat planting technology, specifically, it relates to a single-row planting device for wheat planting. Background Technology

[0002] A single-row planting device for wheat is an agricultural machine specifically designed for wheat breeding experiments, variety comparisons, or precision planting, ensuring that each seed receives equal growing space and resources.

[0003] The prior art discloses a single-row, single-seed seeder for wheat breeding nurseries (CN202421033074.0), specifically relating to the field of wheat breeding technology. It includes a storage box, four casters, and a base. The bottom of the storage box is fixedly connected to the base. The four casters are fixedly installed at the four corners of the bottom of the storage box. A guide plate is fixedly connected inside the storage box. A guide cylinder is fixedly connected to the bottom of the guide plate. A vertical pipe is fixedly connected to the bottom of the guide cylinder, and the bottom of the vertical pipe penetrates the base. A horizontal plate is fixedly connected to one side of the storage box, and a soil covering component is provided at the bottom of the horizontal plate.

[0004] Depending on the planting location, the spacing between each seed in a single row of wheat varies. Current technology uses a motor to drive a rotating shaft, which in turn moves two partitions in opposite directions. When the partition at the top of the gear approaches the riser, it blocks the wheat seeds, while the partition at the bottom of the gear moves away from the riser, allowing the wheat seeds between the two partitions to fall out of the riser. However, current technology cannot effectively control the interval between seed falls by using the toothed plate and the partitions, thus failing to control the planting spacing of a single row of wheat.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the aforementioned technical problem of being unable to control the spacing of single-row wheat planting, the basic concept of the technical solution adopted by this utility model is: a single-row planting device for wheat planting, including a walking wheel, which is set above the ground;

Several arc blocks for sowing wheat seeds are located on both sides of the central plate. The arc blocks are fixedly connected to the central plate. There is a gap between each arc block. The gap between one group of arc blocks is larger than that between the other group. A feeding cavity is located above the central plate. A stirrer that can prevent wheat seeds from clogging when sowing is installed inside the feeding cavity.

[0008] In a preferred embodiment of the present invention, a seed transfer box is fixedly provided below the delivery cavity, and a discharge port is provided on the bottom surface of the delivery cavity. The discharge port extends into the seed transfer box and is fixedly connected to the seed transfer box. A sowing hole is provided on the bottom wall of the seed transfer box.

[0009] In a preferred embodiment of this utility model, a side plate is fixedly provided on one side of each of the two sets of arc blocks. The side plate, the center plate, and the arc blocks are all arranged inside the seed transfer box. The walls of the side plate, the center plate, and the arc blocks are in close contact with the wall of the seed transfer box. An electric telescopic rod is fixedly provided on the inner wall of the seed transfer box. The output shaft of the electric telescopic rod is rotatably connected to one side of a side plate.

[0010] In a preferred embodiment of this utility model, the interval adjustment structure further includes a chain, a sprocket, a gear, a first transmission rod, and a common telescopic rod. The common telescopic rod is fixed to one side of the seed transfer box. The telescopic end of the common telescopic rod extends into the seed transfer box and is rotatably connected to one side of the side plate. A sprocket is fixed to the other end wall of the common telescopic rod, and a sprocket is fixed to one side of the traveling wheel. The two sprockets are driven by a chain.

One end of the first transmission rod is semi-circular.

[0011] In a preferred embodiment of the present invention, the interval adjustment structure further includes an elastic rod and a second transmission rod. One end of the stirrer is fixedly connected to the wall of the elastic rod, and one end of the elastic rod is fixedly connected to one side of the second transmission rod. One end of the second transmission rod is semi-circular, and the second transmission rod can abut against the first transmission rod.

[0012] In a preferred embodiment of this utility model, the interval adjustment structure further includes a spring and a sliding plate. A movable groove is provided on one side of the dispensing cavity. One side of the second transmission rod is fixedly connected to one side of the sliding plate. The sliding plate is slidably connected to the movable groove. The bottom wall of the spring is fixedly connected to one end of the spring. The other end of the spring is fixedly connected to the top surface of the dispensing cavity. A guide rod is provided inside the spring.

[0013] In a preferred embodiment of this utility model, a U-shaped plate is provided on one side of the walking wheel, and one side of the walking wheel is rotatably connected to both ends of the U-shaped plate. The two sides of the U-shaped plate are fixedly connected to both ends of the handle.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. When the arc block with more gaps moves to below the discharge port, the gaps between the arc blocks are smaller, and the seeds fall quickly. When the sowing hole of the arc block with fewer gaps moves to below the discharge port, the gaps between the gaps are larger, and the seeds fall slowly. The sowing hole and the discharge port are opposite each other, and the wheat seeds in the feeding chamber fall out of the discharge port. When one side plate rotates, it drives the arc block to rotate, and the gap rotates to the discharge port, and the wheat seeds fall into the gap. As the arc block rotates, when it rotates to the sowing hole, the wheat seeds fall out of the sowing hole. The positions of the two sets of arc blocks can be adjusted as needed, and the planting spacing of single-row wheat seeds can be adjusted.

[0016] 2. When the first transmission rod rotates to the end of the second transmission rod, the first transmission rod abuts against the second transmission rod, causing the second transmission rod to move upward, which in turn drives the spring to extend and retract. The second transmission rod drives the elastic rod and the agitator upward, and the agitator stirs up and down in the feeding chamber to prevent the wheat seeds from clogging and being unable to enter the feeding port.

The following embodiments are used to illustrate this utility model.

[0027] A single-row planting device for wheat cultivation, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an interval adjustment structure is installed on one side of the walking wheel 1. A central plate 18 is installed on one side of the walking wheel 1, which can move according to the pit spacing. Several arc blocks 19 for sowing wheat seeds are installed on both sides of the central plate 18. The arc blocks 19 are fixedly connected to the central plate 18, with gaps between each arc block 19. The gaps between one group of arc blocks 19 are larger than those between the other groups. A feeding chamber 7 is installed above the central plate 18. Inside the feeding chamber 7 is a stirrer 20 that prevents the wheat seeds from clogging during sowing. A seed transfer device is fixed below the feeding chamber 7. The bottom surface of the feeding chamber 7 of the box 2 is provided with a discharge port, which extends into the seed transfer box 2 and is fixedly connected to the seed transfer box 2. A sowing hole is opened on the bottom wall of the seed transfer box 2. A side plate 17 is fixedly provided on one side of each of the two sets of arc blocks 19. The side plate 17, the center plate 18 and the arc blocks 19 are all set inside the seed transfer box 2. The walls of the side plate 17, the center plate 18 and the arc blocks 19 are in close contact with the wall of the seed transfer box 2. An electric telescopic rod 15 is fixedly provided on the inner wall of the seed transfer box 2. The output shaft of the electric telescopic rod 15 is rotatably connected to one side of a side plate 17.

[0028] A perforation is provided on one side of the seed transfer box 2, through which the power cord of the electric telescopic rod 15 passes. According to planting needs, the power supply of the electric telescopic rod 15 is first connected. The electric telescopic rod 15 drives the side plate 17 and two sets of arc blocks 19 to move. The other side plate 17 drives the end of the ordinary telescopic rod 16. When the arc block 19 with more gaps moves to below the discharge port, the gap between the arc blocks 19 is smaller, and the seeds fall quickly. When the sowing hole of the arc block 19 with fewer gaps moves to below the discharge port, the gap between the gaps is larger, and the seeds fall slowly. The sowing hole and the discharge port are opposite each other, and the wheat seeds in the feeding chamber 7 fall out from the discharge port. When one side plate 17 rotates, it drives the arc block 19 to rotate. The gap rotates to the discharge port, and the wheat seeds fall into the gap. As the arc block 19 rotates, when it rotates to the sowing hole, the wheat seeds fall out from the sowing hole. The positions of the two sets of arc blocks 19 can be adjusted as needed, and the planting spacing of the single row of wheat seeds can be adjusted.

[0029] A single-row planting device for wheat cultivation, such as Figure 1 , Figure 2 and Figure 6As shown, the walking wheel 1 is positioned above the ground. The interval adjustment structure also includes a chain 5, a sprocket 6, a gear 8, a first transmission rod 9, and a common telescopic rod 16. The common telescopic rod 16 is fixed to one side of the seed transfer box 2. The telescopic end of the common telescopic rod 16 extends into the seed transfer box 2 and is rotatably connected to one side of the side plate 17. A sprocket 6 is fixed to the other end of the common telescopic rod 16. A sprocket 6 is fixed to one side of the walking wheel 1. The two sprockets 6 are driven by the chain 5. A gear 8 is also fixed to the wall of the common telescopic rod 16. One end of the gear 8 is fixedly connected to one end of the first transmission rod 9. One end of the first transmission rod 9 is semi-circular. A U-shaped plate 21 is provided on one side of the walking wheel 1. Each side of the walking wheel 1 is rotatably connected to both ends of the U-shaped plate 21. Each side of the U-shaped plate 21 is fixedly connected to both ends of the handle 3. Each side of the dispensing cavity 7 is fixedly connected to one end of a connecting rod 4. The other ends of the two connecting rods 4 are fixedly connected to both ends of the handle 3.

[0030] Pushing handle 3 moves it, which pushes U-shaped plate 21. U-shaped plate 21 drives walking wheel 1 to rotate, walking wheel 1 drives sprocket 6 to rotate, sprocket 6 drives chain 5, chain 5 drives another sprocket 6, and ordinary telescopic rod 16 rotates accordingly. A spring and guide rod are provided between the telescopic end and the other end cavity of ordinary telescopic rod 16. The end of ordinary telescopic rod 16 drives side plate 17 to rotate, and the wall of ordinary telescopic rod 16 drives gear 8 to rotate. The first transmission rod 9 rotates accordingly. When walking wheel 1 rotates, side plate 17 drives arc block 19 to rotate for sowing, which makes sowing more convenient.

[0031] A single-row planting device for wheat cultivation, such as Figure 1 and Figure 5 As shown, the interval adjustment structure also includes an elastic rod 10 and a second transmission rod 11. One end of the stirrer 20 is fixedly connected to the wall of the elastic rod 10, and one end of the elastic rod 10 is fixedly connected to one side of the second transmission rod 11. One end of the second transmission rod 11 is semi-circular, and the second transmission rod 11 can abut against the first transmission rod 9. The interval adjustment structure also includes a spring 12 and a sliding plate 13. A moving groove 14 is provided on one side of the dispensing cavity 7. One side of the second transmission rod 11 is fixedly connected to one side of the sliding plate 13. The sliding plate 13 is slidably connected to the moving groove 14. The bottom wall of the spring 12 is fixedly connected to one end of the spring 12, and the other end of the spring 12 is fixedly connected to the top surface of the dispensing cavity 7. A guide rod is provided inside the spring 12.

[0032] When the first transmission rod 9 rotates to the end of the second transmission rod 11, the first transmission rod 9 abuts against the second transmission rod 11, causing the second transmission rod 11 to move upward, which drives the spring 12 to extend and retract. The second transmission rod 11 drives the elastic rod 10 and the agitator 20 upward. The agitator 20 stirs up and down in the feeding chamber 7 to prevent the wheat seeds from clogging and being unable to enter the feeding port.

[0033] The working principle of this utility model is as follows: Pushing the handle 3 moves the U-shaped plate 21, which in turn drives the traveling wheel 1 to rotate. The traveling wheel 1 drives the sprocket 6 to rotate, which in turn drives the chain 5. The chain 5 drives another sprocket 6, causing the ordinary telescopic rod 16 to rotate. A spring and guide rod are installed between the telescopic end and the other end cavity of the ordinary telescopic rod 16. The end of the ordinary telescopic rod 16 drives the side plate 17 to rotate, and the wall of the ordinary telescopic rod 16 drives the gear 8 to rotate. The first transmission rod 9 rotates accordingly. When the traveling wheel 1 rotates, the side plate 17 drives the arc block 19 to rotate for sowing, making sowing more convenient. A through hole is provided on one side of the seed box 2, through which the power cord of the electric telescopic rod 15 passes. According to planting needs, the power supply of the electric telescopic rod 15 is first connected. The electric telescopic rod 15 drives the side plate 17 and the two sets of arc blocks 19 to move. The other side plate 17 drives the end of the ordinary telescopic rod 16. When the arc block 19 with more gaps moves to the desired position... When the seeds are below the feed inlet, the gaps between the arc blocks 19 are smaller, and the seeds fall quickly. When the sowing holes of the arc blocks 19 with smaller gaps move to below the discharge outlet, the gaps are larger, and the seeds fall slowly. The sowing holes and the discharge outlet are opposite each other, and the wheat seeds in the feeding chamber 7 fall out of the discharge outlet. When one side plate 17 rotates, it drives the arc blocks 19 to rotate, and the gaps rotate to the discharge outlet, and the wheat seeds fall into the gaps. As the arc blocks 19 rotate, when they rotate to the sowing holes, the wheat seeds fall out of the sowing holes. The positions of the two sets of arc blocks 19 can be adjusted as needed, and the planting spacing of single-row wheat seeds can be adjusted. When the first transmission rod 9 rotates to the end of the second transmission rod 11, the first transmission rod 9 abuts against the second transmission rod 11, causing the second transmission rod 11 to move upward, driving the spring 12 to extend and retract. The second transmission rod 11 drives the elastic rod 10 and the stirrer 20 upward. The stirrer 20 stirs up and down in the feeding chamber 7 to prevent the wheat seeds from clogging and being unable to enter the feed inlet.
