Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cotton planting equipment, and particularly relates to a seeding device for small-plot cotton planting. BACKGROUND

[0002] In the field of cotton planting, the seeding mode and equipment are obviously different for different scales of planting plots. For large plots, large cotton seeders are used for seeding, while for small plots owned by many individual farmers, the area of the small plots is relatively small and the terrain can be relatively complex. The large seeder is difficult to operate flexibly on the small plot, and is prone to cause seed waste and land damage. Therefore, in actual production, individual farmers can only choose manual planting or use a small manual seeder for seeding.

[0003] The seeding main body of the existing small manual seeder is a rotatable seeding turntable, and the inside of the seeding turntable is designed to have a space for placing seeds. On the edge of the turntable, a plurality of protruding conical discharge ports are arranged at equal distances. In the actual seeding process, the operator pushes the seeder to rotate the seeding turntable, and each conical discharge port is inserted into the ground in turn. When the conical discharge port is inserted into the ground, the discharge port is opened by a specific mechanism, and the seeds flow into the ground from the discharge port under the action of their own gravity. With the continuous rotation of the seeding turntable, the conical discharge port leaves the ground, at which time the discharge port is closed, and the next conical discharge port enters the ground, and the cycle is repeated to realize continuous seeding operation.

[0004] However, the seeding depth of this small manual seeder is affected by the weight of the seeds and the pushing force of the operator. In the early stage of seeding, the number of seeds is large and the quality is heavy, and under the action of the pushing force, the conical discharge port is inserted into the ground relatively deep, so the seeding is relatively deep. With the progress of seeding, the number of seeds decreases and the quality lightens, and under the action of the same pushing force, the depth of the conical discharge port inserted into the ground gradually becomes shallow, resulting in gradually shallow seeding depth, which leads to uneven overall seeding depth, affecting the uniformity of emergence, and further affecting the yield and quality of cotton.

[0035] The application provides a seeding device for small plot cotton planting, which is used for stabilizing the planting depth of cotton seeds and improving the uniformity of seedling emergence.

[0036] Please refer to Figures 1 to 6 The application provides a seeding device for small plot cotton planting, which comprises:

[0037] The seeding device comprises a seeding main frame, a furrow opener 01, a seeder 02 and a soil covering structure. The seeding main frame is sequentially provided with a front end roller 03, a furrow column 04, a rotating shaft 05 and a rear end roller 06. The furrow opener 01 is connected to the furrow column 04, and the bottom end of the furrow opener 01 extends downward and is inserted into the ground, and the furrow opener 01 is used for opening a furrow on the ground. The rotating shaft 05 is connected to the front end roller 03 through a connecting piece. The seeder 02 is arranged on the seeding main frame and connected to the rotating shaft 05. The seeder 02 cooperates with the rotating shaft 05 to sprinkle cotton seeds into the furrow. The soil covering structure is arranged on the seeding main frame and located between the rotating shaft 05 and the rear end roller 06. The soil covering structure is used for covering the soil in the furrow.

[0038] The seeding main frame is composed of a left side support plate 07 and a right side support plate 08. The left side support plate 07 and the right side support plate 08 are arranged in parallel. The two ends of the front end roller 03 are connected to the left side support plate 07 and the right side support plate 08 respectively. The two ends of the rear end roller 06 are also connected to the left side support plate 07 and the right side support plate 08 respectively.

[0039] The front end roller 03 and the rear end roller 06 are movably connected to the front end and the rear end of the seeding main frame respectively. The front end roller 03 and the rear end roller 06 are in a free rotating state. The front end roller 03 and the rear end roller 06 abut against the ground of the planting land. The seeding main frame moves on the ground through the front end roller 03 and the rear end roller 06.

[0040] The furrow column 04 is fixed on the seeding main frame and located behind the front end roller 03. The furrow opener 01 is connected to the furrow column 04, and the bottom end of the furrow opener 01 extends downward and can be inserted into the ground. The bottom end of the furrow opener 01 has a certain shape and edge to effectively cut into the ground soil. When the seeding main frame advances, the furrow opener 01 is driven by the furrow column 04 to open a furrow with a certain depth and width on the ground, providing space for the seeding of cotton seeds.

[0041] The height of the bottom end of the furrow opener 01 is lower than the height of the lowest point of the front roller 03, that is, when the front roller 03 is on the ground, the bottom end of the furrow opener 01 is inserted into the ground, and a certain height difference is maintained between the bottom end of the furrow opener 01 and the front roller 03. The height difference is, for example, 2 cm, 3 cm, 5 cm, etc. The height difference is the depth of the trench, and the height difference is set according to the required depth of the planted cotton seeds. Here, no limitation is made.

[0042] The rotating shaft 05 is installed on the seeding main body frame and is located behind the furrowing column 04. The rotating shaft 05 is connected to the front roller 03 through a connecting piece, and when the seeding main body frame advances, the front roller 03 rolls to drive the rotating shaft 05 to rotate. The rotating shaft 05 drives the seed sower 02 to operate through its rotation. The seed sower 02 is designed with a seed storage space and a seed distribution wheel inside. When the rotating shaft 05 rotates, the rotating shaft 05 drives the seed distribution wheel to rotate, so that the seed distribution wheel accurately spreads the cotton seeds into the trench opened by the furrow opener 01 at the appropriate position. The seed distribution wheel inside the seed sower 02 is detachably arranged, so that different specifications of seed distribution wheels can be replaced.

[0043] The covering structure is arranged on the seeding main body frame and is located between the rotating shaft 05 and the rear roller 06. The covering structure has a certain shape and structure, which can push the soil on both sides of the trench back into the trench when the seeding main body frame advances, cover the seeds scattered in the trench, and ensure that the seeds are buried to the appropriate depth underground. After covering, the ground is leveled and compacted by the rear roller 06 to ensure that the soil is in contact with the cotton seeds.

[0044] In this embodiment, during the advancement of the seeding main body frame, the front roller 03 first levels the land, then the furrow opener 01 opens the trench, then the seed sower 02 uniformly spreads the cotton seeds into the trench, and then the covering structure backfills the soil into the trench to cover the cotton seeds, and finally the rear roller 06 levels the land again, thereby realizing the trenching-seeding-covering process of the cotton seeds. The bottom end of the furrow opener 01 has a certain depth difference with the lowest point of the front roller 03, so that the trenching depth of the furrow opener 01 remains unchanged during the advancement, and is not affected by the weight of the seeds. Therefore, compared with the existing small manual seeding machine, the present application can maintain the overall seeding depth consistent, improve the uniformity of seedling emergence, and improve the yield and quality of cotton.

[0045] In addition, the present application can simultaneously perform multi-row seeding, thereby improving the seeding efficiency.

In the embodiment, the connection between the furrowing device 01 and the furrowing column 04 is realized through the limiting needle. Specifically, the connecting block 09 is arranged on the furrowing column 04, the vertical through hole is arranged on the connecting block 09, the furrowing device 01 is inserted into the through hole from bottom to top, and the limiting needle is transversely penetrated through the connecting block 09 and the furrowing device 01, so as to limit the up-down movement of the furrowing device 01 in the through hole. In the embodiment, the connection between the furrowing device 01 and the connecting block 09 is realized through the limiting needle, and the quick installation and disassembly of the furrowing device 01 can be realized.

[0047] In the optional embodiment, the height of the furrowing device 01 on the connecting block 09 is adjustable. In the furrowing process, the lowest point of the furrowing device 01 is always lower than the lowest point of the front end roller 03, so that the furrowing device 01 is inserted into the underground furrowing groove when the front end roller 03 rolls on the ground. The adjustable height can adapt to different planting depths according to different soils. For example, the groove depth is adjusted to be shallow for the soil with high humidity.

[0048] In the optional embodiment, the furrowing column 04 is provided with a plurality of connecting blocks 09, and the plurality of connecting blocks 09 are arranged at equal intervals on the furrowing column 04. In the embodiment, the furrowing column 04 is provided with a plurality of connecting blocks 09, and one furrowing device 01 can be connected to each connecting block 09. Therefore, multiple furrowing grooves can be dug at the same time, so as to improve the planting efficiency.

[0049] The interval between adjacent connecting blocks 09 is 7cm-20cm. In specific use, five connecting blocks 09 are arranged on the furrowing column 04, and one furrowing device 01 is connected to each of three connecting blocks 09, so as to realize the planting of three rows of cotton seeds. According to the needs, the number of furrowing devices 01 can be increased / decreased to meet the planting needs of different sizes of land.

[0050] The application adopts a manual pushing mode. In an optional embodiment, a hand pushing handle 10 is further arranged on the seeding main body frame, and a rubber sleeve is arranged on the hand pushing handle 10.

In this embodiment, the first gear 11 and the second gear 12 rotate synchronously through the chain belt 13, the end of the rotating shaft 05 penetrates out of the side of the seeding main frame, the first gear 11 is located outside the seeding main frame, and the second gear 12 is also located outside the seeding main frame. The two gears are connected through the chain belt 13. When the seeding main frame advances, the front roller 03 rotates, the rotating shaft 05 rotates through the chain belt 13, and the rotating shaft 05 rotates to cooperate with the seeder 02 to scatter cotton seeds into the trench.

[0052] In an alternative embodiment, the first gear 11 and the rotating shaft 05 are connected in a detachable manner. In this embodiment, the first gear 11 is detachable, so that different specifications and sizes of the first gear 11 can be replaced. Thus, by replacing the first gear 11 of different sizes while the second gear 12 remains unchanged, the planting spacing (in the forward direction) can be adjusted.

[0053] In an alternative embodiment, the covering structure includes a covering column 14 and a triangular covering plate 15. The covering column 14 is connected to the cross rod 16 on the seeding main frame, and the triangular covering plate 15 is connected to the covering column 14. The rear end of the triangular covering plate 15 is inclined downward.

[0054] The covering column 14 and the seeding main frame can be fixedly connected by welding, bolt connection, buckle connection, etc. The covering column 14 can accurately follow the advancement of the seeding main frame, providing stable support for the covering work of the triangular covering plate 15.

[0055] The triangular covering plate 15 is in the shape of a triangle as a whole. The triangular covering plate 15 is connected to the covering column 14 at a connection position located on the side of the covering column 14 close to the seeding trench. The connection can be achieved by welding, riveting, or bolt connection, etc. to ensure that the connection between the triangular covering plate 15 and the covering column 14 is firm and will not loosen or fall off during the covering process. The rear end of the triangular covering plate 15 is inclined downward, which enables the triangular covering plate 15 to better contact the soil on both sides of the trench when the seeding main frame advances, and smoothly push the soil into the trench.

[0056] The covering column 14 advances together with the seeding main frame under the driving of the seeding main frame. When the rear end of the triangular covering plate 15 contacts the soil on both sides of the trench, the soil gradually moves in the direction of the trench under the action of the covering plate due to the downward inclination of the rear end of the triangular covering plate 15. As the seeding main frame advances, the triangular covering plate 15 continuously pushes the soil on both sides of the trench into the trench to cover the previously scattered seeds.

[0057] In an alternative embodiment, a third gear 17 is arranged on the rotating shaft 05, and the third gear 17 is used to connect with a fourth gear 18 on the seed sower 02. In this embodiment, the third gear 17 is mounted on the rotating shaft 05 and rotates synchronously with the rotating shaft 05. A connecting hole 19 is arranged on the rotating shaft 05, and the third gear 17 is sleeved on the rotating shaft 05 and connected with the connecting hole 19 through a bolt. The number of the connecting holes 19 arranged on the rotating shaft 05 is the same as the number of the connecting blocks 09 on the furrow opener 04. When the number of the furrow opener 01 is increased, the number of the third gear 17 and the seed sower 02 is also increased synchronously.

[0058] In this alternative embodiment, a fixing plate 20 is arranged on the seed sowing body frame, and a notch 21 is arranged on the fixing plate 20 corresponding to the position of the third gear 17. The seed sower 02 is fixed on the fixing plate 20 and inserted into the notch 21 to connect with the third gear 17.

[0059] The fixing plate 20 is made of metal plate material and has certain strength and rigidity, which can provide stable support for the installation of the seed sower 02 and the connection of the gear. The fixing plate 20 is fixed on the seed sowing body frame through a bolt. A notch 21 is arranged on the fixing plate 20 corresponding to the position of the third gear 17. The shape and size of the notch 21 match the meshing part of the third gear 17 and the fourth gear 18. The design of this notch 21 enables the driving part of the seed sower 02 to be inserted therein, realizing the connection of the third gear 17 and the fourth gear 18, while not affecting the normal rotation of the gears. The seed sower 02 is arranged in an inverted conical shape, with the upper end being large and the lower end being small. The lower end can pass through the notch 21 of the fixing plate 20, and the upper end is located above the fixing plate 20. The seed sower 02 and the fixing plate 20 can be connected through a bolt or a buckle. The lower part of the seed sower 02 extends to the upper part of the trench, and when the furrow opener 01 opens a trench on the land, the seed sower 02 pours cotton seeds into the trench to realize sowing.

[0060] In addition, in this application, the furrow opener 04, the rotating shaft 05 and the cross rod 16 are arranged in parallel with each other, and all of them are connected with the seed sowing body frame in a detachable manner.
