Description

Technical Field

[0001] This invention belongs to the field of cotton planters, specifically relating to a cotton experimental field planter and its planting method. Background Technology

[0002] Cotton seeds used for experimental field planting are usually selected from cotton bolls with good growth. After harvesting, they are obtained by ginning with a roller gin. A layer of short fibers remains on the surface of the cotton seeds. The cotton seeds are not subsequently treated with concentrated sulfuric acid to remove fibers, which makes the cotton seeds very easy to stick together and entangle during the soaking and manual sowing process.

[0003] The sowing of cotton in experimental fields differs from that in ordinary fields. Experimental fields typically plant cotton materials in rows about 7 meters long. The number of rows varies depending on the material. The experimenters mainly use manual sowing carts for sowing, which requires two people to push and pull the carts. Another person is also needed to manually break up the knotted cotton seeds and evenly put them into the sowing tube. The sowing process requires frequent stops and turns, and the whole process requires a lot of manpower. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a cotton experimental field planter and its planting method, which can effectively reduce the manpower input during experimental field planting and improve planting efficiency.

[0005] The specific technical solution adopted in this invention is as follows:

[0006] A cotton experimental field seeder includes a frame, wheels, and a seeding tube. A feed hopper is provided at the upper end of the seeding tube, and a furrowing assembly is provided at the lower end. A drive device is also provided. The drive device includes a walking motor, a battery, and a first sprocket coaxially mounted on the frame. A second sprocket is provided at the output end of the walking motor. The second sprocket and the first sprocket form a chain drive connection. The battery is fixedly connected to the frame and located above the walking wheels. The walking wheels are located at the front end of the frame, and the furrowing assembly is located at the rear side of the walking wheels.

[0007] The machine frame is equipped with a press wheel at the rear, and the trenching assembly is located between the press wheel and the traveling wheel. The trenching assembly includes a trenching shovel and a soil covering wheel.

[0008] The seeding tube is equipped with a fiber-removing seed metering device located between the feed hopper and the furrowing shovel. The fiber-removing seed metering device includes a drive motor, a seed stripping sleeve, and a seed stripping roller. The side wall of the seed stripping roller is provided with a concave seed-carrying groove wound in a spiral direction. The seed stripping roller is rotated inside the seed stripping sleeve by the drive motor. The input end of the seed stripping sleeve is connected to the feed hopper through the seeding tube, and the output end of the seed stripping sleeve is connected to the furrowing shovel through the seeding tube. Cotton seeds fall into the seed-carrying groove under the action of gravity and are transferred from the input end to the output end of the seed stripping sleeve as the seed stripping roller rotates.

[0009] The side wall of the seed stripping sleeve is provided with strip-shaped gathering plates. The cross-section of the gathering plates is triangular. Two sets of gathering plates are provided and located above the seed stripping roller. The lower side of the gathering plates is separated from the seed stripping roller. The two sets of gathering plates are symmetrically arranged on both sides of the seed stripping roller. The upper side of the gathering plates forms a U-shaped groove structure. The width of the gap between the gathering plates is the same as the width of the seed carrying groove.

[0010] The sidewall of the seed stripping roller is covered with a friction rubber layer.

[0011] The seed stripping roller has a hollow structure and is equipped with a seed dispensing mechanism. The seed dispensing mechanism includes a cam rod and a telescopic column. The cam rod passes through the hollow inner cavity of the seed stripping roller and is fixedly connected to the frame. The two ends of the cam rod are rotatably connected to the seed stripping roller via bearings. The teeth on the outer circumference of the seed stripping roller are connected to the drive motor via gear transmission. The telescopic column passes through the side wall of the seed stripping roller and exits through the seed carrying groove. A return spring is provided between the telescopic column and the inner wall of the seed stripping roller. The end of the telescopic column on the inner side of the seed stripping roller abuts against the cam rod. The convex side of the vertical section of the cam rod faces the output end of the seed stripping sleeve.

[0012] The rear end of the frame is provided with a push rod, the fixed end of which is hinged to the frame. The middle section of the push rod is also provided with a forward / reverse thread adjustment rod between it and the frame. The lifting angle of the push rod relative to the frame is adjusted by rotating and extending the forward / reverse thread adjustment rod.

[0013] Includes the following steps,

[0014] S1. Put cotton seeds into the feed hopper of the seeder;

[0015] S2. Start the seeder. The walking motor drives the walking wheels to rotate. The fiber removal and seed metering device separates the cotton seed clumps discharged from the hopper into the seeding tube and drops them into the lower section of the seeding tube.

[0016] S3. Using a furrowing shovel, planting furrows are dug on the ground of the experimental field. Cotton seeds fall into the planting furrows. A soil covering wheel and a pressing wheel are set behind the furrowing shovel. The soil covering wheel is used to fill the planting furrows with soil, and the pressing wheel is used to press the cotton seeds into the planting furrows, thus completing the sowing operation.

[0017] The beneficial effects of this invention are:

[0018] This invention eliminates the need for manual dragging of the seeder by adding a walking motor and a storage battery, thereby improving the seeder's operating efficiency, reducing reliance on personnel, and increasing the friction between the walking wheels and the ground by pressing the storage battery onto the walking wheels, which facilitates subsequent furrowing, sowing, covering, and compaction operations, thus improving sowing efficiency.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] Specific implementation examples Figure 1 As shown, the present invention is a cotton experimental field seeder, including a frame 1, a traveling wheel 2 and a seeding pipe 3. A feed hopper 4 is provided at the upper end of the seeding pipe 3, and a furrowing shovel 5 is provided at the lower end. A drive device is added, which includes a traveling motor 6, a storage battery 7 and a first sprocket 8 coaxially arranged with the traveling wheel 2, all mounted on the frame 1. A second sprocket 9 is provided at the output end of the traveling motor 6. The second sprocket 9 and the first sprocket 8 form a chain drive connection. The storage battery 7 is fixedly connected to the frame 1 and located above the traveling wheel 2. The traveling wheel 2 is located at the front end of the frame 1, and the furrowing shovel 5 is located at the rear side of the traveling wheel 2.

[0026] like Figure 1 As shown, by pressing the battery 7 onto the walking wheel 2, the grip of the walking wheel 2 is increased, the ditching depth and ditching force of the ditching shovel 5 are improved, and a better ditching and planting effect is ensured. By setting the walking motor 6 to drive the walking wheel 2 to provide power for the seeder, manual pulling is eliminated and work efficiency is improved.

[0027] Furthermore, a press wheel 10 is provided on the rear side of the frame 1, and the trenching shovel 5 is disposed between the press wheel 10 and the traveling wheel 2. The trenching assembly 5 includes a trenching shovel and a covering wheel. The covering wheel is plate-shaped and disposed on the rear side of the trenching shovel, and is used to cover the soil scraped on both sides of the trenching shovel back into the furrow.

[0028] The press roller 10 supports the ground, reducing the physical exertion of the seeder during operation. At the same time, the press roller 10 presses down the cotton seeds to ensure planting results.

[0029] Furthermore, such as Figure 3 and Figure 4 As shown, the seeding pipe 3 is also equipped with a fiber removal and seed dispensing device located between the feed hopper 4 and the furrowing shovel 5. The fiber removal and seed dispensing device includes a drive motor 11, a seed stripping sleeve 12, and a seed stripping roller 13. The side wall of the seed stripping roller 13 is provided with a concave seed carrying groove 14 wound in a spiral direction. The seed stripping roller 13 is rotatably mounted inside the seed stripping sleeve 12 by means of the drive motor 11. The input end of the seed stripping sleeve 12 is connected to the feed hopper 4 through the seeding pipe 3, and the output end of the seed stripping sleeve 12 is connected to the furrowing shovel 5 through the seeding pipe 3. Cotton seeds fall into the seed carrying groove 14 under the action of gravity and are transferred from the input end to the output end of the seed stripping sleeve 12 as the seed stripping roller 13 rotates.

[0030] When cotton seeds fall into the seed stripping roller 13, the rotation of the seed stripping roller 13 causes the cotton seeds to be torn off from their clumps and fall toward the furrowing shovel 5, thus completing the seed clump separation operation.

[0031] Furthermore, such as Figure 3 As shown, the side wall of the seed stripping sleeve 12 is provided with strip-shaped gathering plates 15. The cross-section of the gathering plates 15 is triangular. Two sets of gathering plates 15 are provided and located above the seed stripping roller 13. The lower side of the gathering plates 15 and the seed stripping roller 13 form a gap. The two sets of gathering plates 15 are symmetrically arranged on both sides of the seed stripping roller 13. The upper side of the gathering plates 15 forms a U-shaped groove structure. The width of the gap between the gathering plates 15 is the same as the width of the seed carrying groove 14.

[0032] The sidewall of the seed stripping roller 13 is covered with a friction rubber layer 16.

[0033] The friction layer 16 increases the surface friction of the seed stripping roller 13. When the cottonseed clump falls to the bottom of the U-shaped trough formed by the gathering plate 15, the hairs extending beyond the seed coat are drawn into the gap between the seed stripping roller 13 and the gathering plate 15 by the rotating seed stripping roller 13, and are held in this gap. Under the tearing action of the rotating seed stripping roller 13, the hairs on the outside of the cottonseed are ripped off. Figure 3 As shown, the seed stripping roller 13 rotates clockwise at this time, and the cotton seeds are stuck between the seed stripping roller 13 and the gathering plate 15 on the right. When the seed carrying trough 14 rotates past, the cotton seeds whose fluff is being torn off fall into the seed carrying trough 14. The seed carrying trough 14 is 8-10mm wide. Seeds carrying fluff (usually with a diameter of more than 1cm) cannot fall into the seed carrying trough 14 again because of the obstruction of the seeds that have already fallen into the seed carrying trough 14. As the seed stripping roller 13 rotates, the cotton seeds whose fluff has been partially torn off fall into the subsequent sowing tube 3, completing the sowing. Due to the tearing of the seed stripping roller 13, the cotton seeds close to the seed stripping roller 13 are pulled by its fluff to the space between the seed stripping roller 13 and the gathering plate 15 and are arranged neatly. As the spiral seed carrying trough 14 passes by, the arranged cotton seeds are carried away and discharged in sequence, ensuring the uniformity of sowing.

[0034] like Figure 3 A scraper is provided at the lower end of the gathering plate 15 on the left side, which scrapes off the adhering lint from the seed stripping roller 13.

[0035] Furthermore, the seed stripping roller 13 has a hollow structure and is equipped with a seed dispensing mechanism. The seed dispensing mechanism includes a cam rod 17 and a telescopic column 18. The cam rod 17 passes through the hollow inner cavity of the seed stripping roller 13 and is fixedly connected to the frame 1. The two ends of the cam rod 17 are rotatably connected to the seed stripping roller 13 by means of bearings. The teeth on the outer circumference of the seed stripping roller 13 are connected to the drive motor 11 by means of gear transmission. The telescopic column 18 passes through the side wall of the seed stripping roller 13 and exits in the seed carrying groove 14. A return spring is provided between the telescopic column 18 and the inner wall of the seed stripping roller 13. The end of the telescopic column 18 on the inner side of the seed stripping roller 13 abuts against the cam rod 17. The protruding side of the vertical section of the cam rod 17 faces the output end of the seed stripping sleeve 12.

[0036] When the seed stripping roller 13 rotates, if any cotton seeds get stuck in the seed carrying groove 14, it will prevent the subsequent work from continuing. A cam rod 17 is set up, with the protruding side of the cam rod 17 facing the output end of the seed stripping sleeve 12. When the telescopic column 18 passes through the protruding side as the seed stripping roller 13 rotates, it is pushed out, thereby pushing out any stuck cotton seeds in the seed carrying groove 14, ensuring the continuous sowing.

[0037] Furthermore, such as Figure 1As shown, a push rod 19 is provided at the rear end of the frame 1. The fixed end of the push rod 19 is hinged to the frame 1. A forward and reverse thread adjustment rod 20 is also provided between the middle section of the push rod 19 and the frame 1. The lifting angle of the push rod 19 relative to the frame 1 is adjusted by rotating and extending the forward and reverse thread adjustment rod 20.

[0038] The seeding method based on a seeder includes the following steps:

[0039] S1. Put cotton seeds into the feed hopper 4 of the seeder;

[0040] S2. Start the seeder. The walking motor 6 drives the walking wheels 2 to rotate. The fiber removal and seed discharging device breaks up the cotton seed clumps discharged from the hopper 4 into the seeding tube 3 and drops them into the lower section of the seeding tube 3.

[0041] S3. Using the furrowing shovel 5, planting furrows are dug on the ground of the experimental field. Cotton seeds fall into the planting furrows. A soil covering wheel and a pressing wheel 10 are set behind the furrowing shovel 5. The soil covering wheel is used to fill the planting furrows with soil. The pressing wheel 10 is then used to press the cotton seeds into the planting furrows, thus completing the sowing operation.
