Description

Technical Field

[0001] The utility model relates to the technical field of crop sowing, in particular to a portable corn seeder. Background Art

[0002] In large-scale farmland cultivation, mechanized seeding equipment has become an important means of improving production efficiency and reducing costs. Large seeders can quickly complete a series of operations such as tilling the soil, sowing, and fertilizing, greatly reducing farmers' labor intensity. However, in smaller farmland cultivation, especially family farms or scattered plots, large seeders cannot fully demonstrate their advantages due to limited land area and complex terrain, and may even be unable to operate on these plots, resulting in low utilization of these lands.

[0003] Some manual seeders have appeared on the market, providing convenience for small-scale planting. A handheld seeder with announcement number CN108934317A includes a handle, a feeding hopper, a seed storage barrel, a seed circulation chamber, a seed wheel, a transmission pin, a seeding nozzle and a locator. The seeds enter the seed storage barrel through the feeding hopper. The seed storage barrel contains two cavities. The operator can choose which cavity the seeds can pass through and which part of the seed wheel they will eventually enter, thereby adjusting the single seeding amount and improving the sowing accuracy. The seeds pass through the seed wheel and enter the seeding nozzle. The seeding nozzle is a duckbill-shaped pointed nozzle, and pressure can be applied to make it enter the soil directly without the need for manual groove opening.

[0004] However, while existing manual seeders have solved the problem of small-area planting to a certain extent, they still have some significant shortcomings during use. In newly loosened farmland, the soil is relatively soft, and the locator of the manual seeder is easily buried in the soil when it is pressed against the ground, making it difficult to control the sowing depth. When the locator encounters a large bump, the sowing nozzle may not be fully inserted into the soil, causing the seed to fall directly onto the soil when the nozzle opens, failing to achieve the desired sowing depth. This not only affects seed germination and growth, but can also lead to uneven crop growth, which in turn affects yield and quality. Utility Model Content

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0028] This embodiment mainly describes the structure of the corn planter, which is as follows:

[0029] A portable corn seeder, such as Figure 1-Figure 7 As shown, it includes a seeder 1, a conical plate 101, a rocker 102, a motor 3, a trigger mechanism, a pulley group 4, a transmission shaft 5 and a protrusion 6. A seed storage cylinder, a seed circulation chamber and a seeding wheel are provided in the seeder 1. The seeding wheel is connected to the motor 3. When the motor 3 is started, the seeding wheel rotates to achieve uniform interval discharge of seeds. A gripping handle is provided on the seeder 1. The bottom of the seeder 1 is connected to the conical plate 101. The side of the seeder 1 is installed with the motor 3. The bottom of the seeder 1 is rotatably connected to the rocker 102. The conical plate 1 01 and the seesaw 102 form a complete conical barrel, the transmission shaft 5 is rotatably connected to the bottom of the seeder 1, and the two ends of the transmission shaft 5 are connected with protrusions 6, and the end of the transmission shaft 5 is slidably connected to the seeder 102 together with the protrusions 6. One end of the pulley group 4 is connected to the output shaft of the motor 3, and the other end is connected to the transmission shaft 5. The motor 3 controls the rotation angle of a single start through a preset program or mechanical structure to ensure that the seesaw 102 stops after rotating to a position sufficient to release the seeds. The seeder 1 is provided with a trigger mechanism for controlling the start and stop of the motor 3.

[0030] like Figure 2-Figure 5 As shown, the trigger mechanism includes a pressure sensor 2, a controller 301 and an adjustment component. Adjustment components are provided on both sides of the seeder 1. The adjustment components are used to install the pressure sensor 2 and adjust the installation height of the pressure sensor 2. The seeder 1 is installed with a controller 301, and a mobile power supply is integrated in the controller 301. The controller 301 is respectively connected to the pressure sensor 2 and the motor 3 by wire. The pressure sensors 2 are respectively located on both sides of the seeder 1 and adopt an "AND gate" trigger mechanism. The trigger condition of the pressure sensor 2 requires that the pressure of the land on it reaches a threshold. If the two pressure sensors 2 meet the threshold at the same time, the influence of large soil blocks on signal transmission is reduced.

[0031] like Figure 1 and Figure 5As shown, the adjustment assembly includes a push plate 7, an adjusting screw 8 and a guide rod 9. The adjusting screw 8 is threadedly connected to the seeder 1, the guide rod 9 is slidingly connected to the seeder 1, the bottom of the guide rod 9 is connected to the push plate 7, the bottom of the adjusting screw 8 is rotatably connected to the push plate 7, and a pressure sensor 2 is installed at the bottom of the push plate 7.

[0032] The operator pours the corn seeds to be sown into the seeder 1. The seeder 1 is provided with a seeding wheel that can release the seeds in a quantitative manner. Then the operator holds the handle and inserts the conical plate 101 and the rocker 102 into the soil. At this time, the two pressure sensors 2 are in contact with the soil. When the two pressure sensors 2 meet the trigger conditions at the same time, a sowing signal will be sent to the controller 301. After receiving the signal, the controller 301 starts the motor 3. The motor 3 drives the transmission shaft 5 and the protrusion 6 to rotate through the pulley group 4, thereby driving the rocker 102 to rotate, separate from the conical plate 101, and propel the soil. The seeds fall into the soil through the seeding wheel. Then the seeder 1 is pulled out. After the pressure sensor 2 is separated from the ground, the signal transmission is stopped. The output shaft of the motor 3 of the controller 301 rotates in the opposite direction, driving the transmission shaft 5 and the protrusion 6 through the pulley group 4 to complete the rotation reset of the rocker 102 and complete the sowing process.

[0033] When the sowing depth needs to be adjusted, the operator turns the adjusting screw 8. When the adjusting screw 8 moves up and down, it drives the push plate 7 to move up and down, thereby driving the pressure sensor 2 to move up and down. The push plate 7 maintains smooth movement under the guidance of the guide rod 9, thereby ensuring that the distance between the pressure sensor 2 and the bottom of the conical plate 101 is close to the required sowing depth.

[0034] like Figure 1 and Figure 6 As shown, it also includes an outer frame 10, a deflecting plate 12 and a clamping plate 14. The upper end of the outer frame 10 is connected to the seeder 1, and a cavity 11 is opened at the lower end of the outer frame 10. The deflecting plate 12 is slidably connected to the cavity 11. A positioning groove 13 is opened on the side of the lower end of the outer frame 10. The clamping plate 14 is slidably connected to the positioning groove 13, and the clamping plate 14 is clamped with the deflecting plate 12. When the deflecting plate 12 is fully extended out of the outer frame 10, the bottom of the deflecting plate 12 is lower than the conical plate 101.

[0035] During the sowing process, the seeder 1 is inserted into the soil, and the deflector plate 12 is also inserted. Since the seeder 1 needs to move in a certain direction during sowing, it will naturally tilt. At this time, the deflector plate 12 and the operator are located on both sides of the seeder 1. When the operator pulls out the seeder 1, the tilted deflector plate 12 will push the soil in the direction of movement of sowing to cover the holes formed during sowing, and adjust the extended length of the deflector plate 12 according to the covering requirements. When adjusting the deflector plate 12, pull out the card plate 14, the card plate 14 is disengaged from the deflector plate 12, slide the deflector plate 12 in the cavity 11, and then insert the card plate 14 into the positioning groove 13 to engage with the deflector plate 12, thereby fixing the position of the deflector plate 12.

[0036] like Figure 6 As shown, a pull rope 15 is further included, one end of the pull rope 15 is connected to the outer frame 10 , and the other end is connected to the clamping plate 14 .

[0037] When the card plate 14 is pulled out, the pull rope 15 can hang the card plate 14. After the operator moves the earthmoving blade 12, the card plate 14 can be directly taken out, and the card plate 14 will not be lost.

[0038] like Figure 5 As shown, a compression spring 16 is also included. The adjusting screw 8 is sleeved with the compression spring 16. One end of the compression spring 16 is connected to the seeder 1, and the other end is connected to the push plate 7.

[0039] While adjusting the height of the push plate 7, the compression spring 16 always pushes the push plate 7 downward, so that the adjusting screw 8 is tightly connected to the seeder 1. During the sowing process, the adjusting screw 8 will not loosen easily, keeping the pressure sensor 2 stable.

[0040] like Figure 1 As shown, the seeder 1 further includes a warning light 17 . A handle is provided at the upper end of the seeder 1 , and the handle is connected to the warning light 17 . The warning light 17 is connected to the controller 301 via a wire.

[0041] When the controller 301 starts the motor 3, the prompt light 17 lights up at the same time, so that the operator can intuitively understand whether the sowing is completed to ensure effective sowing every time.

[0042] like Figure 7 As shown, a protective shell 18 is also included. The bottom of the seeder 1 is connected to the protective shell 18, and the protective shell 18 covers the pulley set 4.

[0043] When the seeder 1 is inserted into the soil, the protective shell 18 can protect the pulley group 4 and the output shaft of the motor 3 to ensure the transmission effect of the pulley group 4 and maintain the stable operation of the equipment.

[0044] The operator first pours corn seeds into the seeder 1, which uses a built-in seeding wheel to achieve a fixed amount of seeding. Then, holding the seeder 1 by its handle, the operator inserts the lower end of the seeder 1, which features a tapered plate 101 and a rocker plate 102, into the soil. At this point, pressure sensors 2, mounted on either side of the seeder 1 and adjusted in height by an adjustment assembly, come into contact with the ground. When both pressure sensors 2 meet the triggering conditions simultaneously, a sowing signal is transmitted to the controller 301. Upon receiving this signal, the controller 301 activates the motor 3, which, via the pulley assembly 4, drives the drive shaft 5 and the protrusion 6. This in turn rotates the rocker plate 102 and separates it from the tapered plate 101, pushing the soil apart and allowing the seeds released by the seeding wheel to fall into the soil. After sowing is complete, the seeder 1 is removed, and the pressure sensors 2 disengage from the ground. The controller 301 receives a stop signal and reverses the rotation of the motor 3, which, via the pulley assembly 4, drives the drive shaft 5 and the protrusion 6 to reset the rocker plate 102. Furthermore, to protect the equipment, the pulley assembly 4 and the output shaft of the motor 3 are covered by a protective housing 18. The deflector blade 12 can cover the soil hole after sowing. The extension length of the deflector blade 12 can be adjusted by adjusting the clamping plate 14 to meet different covering requirements. The pull rope 15 makes it easy for the operator to take out the clamping plate 14 after adjusting the deflector blade 12. When the controller 301 starts the motor 3, the warning light 17 lights up synchronously to ensure that the operator can intuitively understand the sowing status.
