[0002] Seeds are the reproductive organs of plants and part of the plant life cycle. They are responsible for transferring the genetic information of the plant from one generation to the next. Seeds are usually composed of seed coat, embryo and endosperm. A seeder is an agricultural machine used to sow seeds evenly into the soil at a certain spacing and depth. It greatly improves sowing efficiency, reduces manual labor, and helps to achieve more uniform crop planting, which may increase crop yield and quality.

[0003] The existing seed sowing method usually involves placing seeds into a sowing device and sowing them by moving the sowing device. However, most of the current sowing equipment uses fixed spacing and depth for sowing, which cannot flexibly adapt to the specific needs of different crops. It is easy to cause crops to be planted too densely or too sparsely, affecting photosynthesis, ventilation and root development, thereby reducing the yield and survival rate of crops. In addition, some equipment with adjustable spacing has a complex structure and requires frequent disassembly and assembly, which is cumbersome to operate and inconvenient to use.

[0004] Therefore, it is necessary to design a seeder that can equidistantly adjust the spacing and planting depth between seeders according to the planting needs of different crops to sow and plant seeds, optimize the growth environment and space, increase the yield and survival rate of crops, improve planting efficiency, and use a flexible and convenient seeder with adjustable seed spacing and depth.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-8 The present invention is further described with specific embodiments.

[0024] A seeder with adjustable seed spacing and depth, such as Figure 1-Figure 6 As shown, it includes a fixing frame 1, a connecting bracket 2, an adjusting mechanism 3 and a control mechanism 4. The connecting bracket 2 is connected to the upper middle side of the fixing frame 1. The connecting bracket 2 has two left and right mounting holes on the upper rear portion for easy installation on a mobile device. The connecting bracket 2 is provided with the adjusting mechanism 3 for equidistantly adjusting the seed spacing. The connecting bracket 2 is provided with the control mechanism 4 for adjusting the depth of seed planting at the front.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, the adjustment mechanism 3 includes a motor 30, a bidirectional screw rod 31, a fixed connecting frame 32, a movable frame 33, a hollow connecting frame 34, a connecting rod 35, a fixed bracket 36 and a seeder 37. The upper right part of the fixed frame 1 is connected to the motor 30, the rear part of the fixed frame 1 is rotatably connected to the bidirectional screw rod 31, the bidirectional screw rod 31 is connected to the output shaft of the motor 30, the middle part of the fixed frame 1 is connected to the fixed connecting frame 32, the bidirectional screw rod 31 is rotatably connected to the fixed connecting frame 32, the left and right parts of the bidirectional screw rod 31 are both connected to the movable frame 33 by threads, the movable frame 33 is slidably connected to the fixed frame 1, and the fixed frame 1 The left and right parts are both slidably connected with two hollow connecting frames 34, the movable frame 33 and the hollow connecting frame 34 are both I-shaped, the left and right parts of the fixed connecting frame 32 are rotatably connected with the connecting rod 35, the movable frame 33 is also rotatably connected with the connecting rod 35, the hollow connecting frame 34 is also rotatably connected with the upper and lower connecting rods 35, the two adjacent connecting rods 35 are rotatably connected, the front side of the movable frame 33 is connected with the fixed bracket 36, the front sides of the hollow connecting frame 34 on the right side of the left part and the hollow connecting frame 34 on the left side of the right part are also connected with the fixed bracket 36, and the fixed bracket 36 is connected with the seeder 37.

[0026] like Figure 1 , Figure 5 and Figure 6 As shown, the control mechanism 4 includes a cylinder 40, a connecting rod 41, a sliding sleeve 42, a connecting column 43 and a slotted wheel 44. The front part of the fixed frame 1 is connected to the left and right cylinders 40, the connecting rod 41 is connected between the telescopic ends of the cylinder 40, the connecting rod 41 is slidably connected to four sliding sleeves 42, the lower side of the sliding sleeves 42 is connected to the connecting column 43, the connecting column 43 is Y-shaped, the connecting column 43 is slidably connected to the fixed bracket 36 at the same longitudinal position, and the lower part of the connecting column 43 is rotatably connected to the slotted wheel 44.

[0027] When the seed spacing and depth need to be adjusted for sowing, this device can be used to make the connecting bracket 2 contact with the moving device, and then use bolts to pass through the mounting holes to fix the connecting bracket 2. Then, according to the planting needs of different crops, the motor 30 on the fixed frame 1 is started, and the bidirectional screw rod 31 is driven to rotate by the motor 30. Under the action of the thread, the mobile frame 33 moves outward at the same time, so that the corresponding connecting rod 35 moves and rotates, so that the hollow connecting frame 34 moves along the fixed frame 1. The mobile frame 33 and the hollow connecting frame 34 are both I-shaped, so that the remaining connecting rods 35 move and rotate, thereby driving the fixed bracket 36 and the seeder 37 to move, and then adjusting the spacing between the seeders 37 equidistantly.

[0028] When the fixed bracket 36 moves, the connecting column 43 is also driven to move. The connecting column 43 is Y-shaped, so that the sliding sleeve 42 moves along the connecting rod 41. After moving to a suitable planting distance, the motor 30 is turned off, and then the cylinder 40 is started according to the planting depth of different crops. The connecting rod 41 is driven downward by the cylinder 40, so that the sliding sleeve 42, the connecting column 43 and the slotted wheel 44 move downward, so that the slotted wheel 44 is inserted into the soil. After being pressed down to a suitable depth, the cylinder 40 is turned off.

[0029] Put the seeds into the seeder 37, and then start the mobile device, and use the mobile device to drive the device to move, so that the grooved wheel 44 rotates to groove the farmland, and at the same time, the seeds in the seeder 37 fall and are sown, thereby achieving equidistant planting of seeds. In this way, the spacing and planting depth between the seeders 37 can be equidistantly adjusted according to the planting needs of different crops to sow and plant the seeds, optimize the growth environment and space, increase the yield and survival rate of crops, improve planting efficiency, and be flexible and convenient to use.

[0030] After planting is completed, the mobile device is turned off, and the cylinder 40 is operated in reverse to move the connecting rod 41 upward, so that the sliding sleeve 42, the connecting column 43 and the slotted wheel 44 move upward, so that the slotted wheel 44 is separated from the ground, and then the cylinder 40 is turned off, and the bolt is removed by reverse rotation to separate the connecting bracket 2 from the mobile device, and then the device can be moved away.

[0031] In this embodiment, both sides of the slotting wheel 44 are provided with slotting ridges. When the lower part of the slotting wheel 44 is pressed down, it breaks through the soil and enters the soil layer, and the slotting ridges thereon squeeze the soil layer accordingly. When the seeder moves, the slotting ridges squeeze the soil layer to generate resistance. This resistance and the weight of the equipment enable the slotting wheel 44 to rotate continuously, turning up the soil layer to both sides, in order to enhance the slotting effect of the slotting wheel and turn up the soil layer to facilitate subsequent soil covering operations.

[0032] After sowing, seeds often need to be covered with soil according to their biological characteristics. Covering with soil can provide good conditions for seed germination and seedling growth, thereby improving the emergence and survival rate of crops, helping to increase crop yields and improve the overall quality of crops.

[0033] like Figure 1 and Figure 7 As shown, it also includes a covering mechanism 5, which includes a guide frame 50, a spring 51, a connecting roller 52, a reciprocating screw rod 53, a movable connecting frame 54 and a connecting plate 55. The lower part of the seeder 37 is slidably connected to the guide frame 50, and the guide frame 50 is connected to the seeder 37 at the same longitudinal position with two left and right springs 51. The lower part of the guide frame 50 is rotatably connected to the left and right reciprocating screw rods 53, and the connecting roller 52 is connected to the side where two adjacent reciprocating screw rods 53 are close to each other. The reciprocating screw rod 53 is threadedly connected to the movable connecting frame 54, and the movable connecting frame 54 is slidably connected to the adjacent guide frame 50. The movable connecting frame 54 is folded, and the front of the movable connecting frame 54 is connected to the connecting plate 55.

[0034] The outer sides of the connecting rollers 52 are provided with friction grooves. Under the action of the springs 51, the connecting rollers 52 are pressed tightly against the soil surface, increasing the friction between them and the ground, so that the reciprocating screw rod 53 rotates continuously. That is, the role of the springs 51 is to adapt to the undulations of the bottom surface and to enhance the friction between the connecting rollers 52 and the ground.

[0035] When the mobile device drives the seeder 37 to move, the connecting roller 52 will also rotate, and the friction force is increased by the friction pattern, so that the reciprocating screw rod 53 rotates, and under the action of the thread, the movable connecting frame 54 moves left and right along the guide frame 50. The movable connecting frame 54 is all folded, which drives the connecting plate 55 to move left and right to move the soil so that the soil covers the seeds. During the movement, when there is a protrusion on the ground, the connecting roller 52 will move upward, so that the movable connecting frame 54, the connecting plate 55 and the guide frame 50 will move upward, and the spring 51 will be squeezed. When the connecting roller 52 is separated from the protruding area, the spring 51 rebounds, and the connecting roller 52 moves downward and resets, so that the movable connecting frame 54, the connecting plate 55 and the guide frame 50 move downward and reset, so that the soil can be automatically moved to cover the seeds during the movement, reducing manual intervention, facilitating adaptation to different terrains for planting, and having strong adaptability.

[0036] like Figure 1 and Figure 8 As shown, a flattening mechanism 6 is also included, and the flattening mechanism 6 includes a rotating connecting frame 60, a torsion spring 61 and a flattening roller 62. The rotating connecting frame 60 is rotatably connected to the front side of the middle part of the fixed bracket 36. The rotating connecting frame 60 is connected to two left and right torsion springs 61 between the adjacent fixed brackets 36. The rotating connecting frame 60 is rotatably connected to the flattening roller 62 at the front lower part. The flattening roller 62 is provided with anti-skid grooves to facilitate anti-skid.

[0037] After covering the seeds with soil, the movement of the fixed bracket 36 will also drive the rotating connecting frame 60 to move, thereby driving the flattening roller 62 to move and rotate to flatten the soil. The anti-skid pattern is used to prevent slipping. During the movement and flattening process, as the soil height varies, the rotating connecting frame 60 and the flattening roller 62 will rotate and then reset, and the torsion spring 61 will deform and then rotate to recover, so that the soil can be automatically flattened after covering the seeds, thereby optimizing the planting environment, reducing the risks of wind erosion and water erosion, and further improving the survival rate of seeds.

[0038] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
