Abstract
Description
Technical Field
[0001] This utility model relates to the field of sowing device technology, specifically a sowing device adapted for dryland rice on slopes. Background Technology
[0002] A seeding device is a type of machinery used in agricultural production. Its main function is to sow seeds evenly into the soil at a predetermined depth, spacing, and density, creating favorable initial conditions for crop growth. Dryland rice refers to a variety of dryland rice grown on slopes. Dryland rice is a type of rice adapted to arid environments. Its main difference from traditional rice is that it has a lower water requirement and can grow in relatively dry conditions, without relying on large amounts of irrigation water or long-term flooding like traditional rice.
[0003] When sowing on slopes, existing sowing devices, with their bottom discharge blades kept horizontal, struggle to adapt to undulating and uneven terrain. This design flaw prevents the discharge blades from automatically adjusting the sowing depth according to changes in ground elevation, resulting in inconsistent seed sowing depth. Specifically, when the sowing device travels to areas with steep slopes, the discharge blades cut too deeply into the soil, sowing the seeds too deeply. Conversely, on gentler slopes or where the ground is raised, the discharge blades cut shallower, sowing the seeds too shallowly. This inconsistency in sowing depth directly affects seed germination rate and growth uniformity, thus impacting crop yield and quality. Therefore, to address these issues, a slope-adaptive sowing device for dryland rice is proposed. Utility Model Content

[0026] Please see Figure 1-6 This utility model provides a technical solution:
[0027] An adaptive sowing device for dryland rice on slopes includes a storage box 1, a vibration motor 2, a hose 3, and an extension frame 4. A height adjustment component 5 is fixedly connected to the bottom of the extension frame 4. A sowing component 6 is installed at the lower end of the height adjustment component 5. The height adjustment component 5 includes a fixed shell 51. An insert groove 52 is opened on the inner side of the fixed shell 51. A linear spring 53 is fixedly connected to the upper end of the insert groove 52. A spring plate 54 is fixedly connected to the bottom end of the linear spring 53. An extension column 55 and a shaft block 56 are fixedly connected to the bottom end of the spring plate 54 in sequence. The sowing component 6 includes a discharge blade 61. A roller 62 is fixedly connected to the outer side of the discharge blade 61. A spring spring 63 is fixedly connected to the outer side of the roller 62. A horizontal plate 64 is fixedly connected to one side of the roller 62. A roller 65 is rotatably connected to one end of the horizontal plate 64. The bottom end of the hose 3 is fixedly connected to the top end of the discharge blade 61. The roller 62 is rotatably connected to the inner side of the shaft block 56.
[0028] As a further implementation of this solution, a stop bar 57 is fixedly connected to one side of the shaft block 56. The stop bar 57 is located at the front end of the hose 3 and at the upper end of the discharge knife 61. A through hole is opened at the upper end of the discharge knife 61. The hose 3 communicates with the inside of the discharge knife 61 through the through hole of the discharge knife 61. With the above arrangement, the seeds can smoothly enter the inside of the discharge knife 61 from the hose 3. The design of the hose 3 does not hinder the up and down movement of the sowing component 6.
[0029] As a further implementation of this solution, a rotating hole 58 is provided on the inner side of the shaft block 56. The rotating hole 58 extends through the inner side of the shaft block 56 in the left and right direction. The inner side of the rotating hole 58 is fixedly connected to one end of the spring 63. With the above arrangement, when idle, the upper end of the discharge knife 61 can be kept in contact with the lower end of the stop bar 57, so that the discharge knife 61 can effectively extend into the ground when sowing.
[0030] As a further implementation of this solution, a vibration motor 2 is fixedly connected to the inside of the storage box 1, and a hose 3 is fixedly connected to the lower end of the storage box 1. A through hole is opened at the lower end of the storage box 1, and the storage box 1 communicates with the inside of the hose 3 through the through hole. Through the above settings, the efficiency of seed transmission is improved, the accumulation and blockage of seeds during the transmission process are reduced, and the uniformity and reliability of sowing are improved.
[0031] As a further implementation of this solution, an extension frame 4 is fixedly connected to the front end of the storage box 1. The bottom end of the extension frame 4 is fixedly connected to the top end of the fixed shell 51 by bolts. Multiple height adjustment components 5 are set. Through the above settings, the structural stability of the device is enhanced. In addition, the setting of multiple height adjustment components 5 provides more support points, enabling the device to better adapt to the undulations of the slope and uneven ground.
[0032] As a further implementation of this solution, a sliding hole is provided at the lower end of the fixed shell 51, and the extension column 55 is slidably connected to the inner side of the sliding hole of the fixed shell 51. The extension column 55 extends out of the outer side of the fixed shell 51, and the baffle 57 has fixed shaft blocks 56 on both sides. Through the above settings, the device can automatically adjust the sowing depth according to the changes in ground level. This design not only improves the adaptability and flexibility of the device, but also enhances the stability of the structure through the fixed shaft blocks 56 on both sides of the baffle 57, ensuring the uniformity and reliability of sowing.
[0033] As a further implementation of this scheme, rollers 62 are fixed on both the left and right sides of the discharge blade 61, and the shaft block 56 is sleeved on the outside of the rollers 62. Rollers 65 rotate at both the front and rear ends of the horizontal plate 64. The lower end of the roller 65 protrudes from the lower end of the horizontal plate 64, and a gap is provided between the bottom end of the roller 65 and the bottom end of the discharge blade 61. With the above settings, the sowing depth and angle can be automatically adjusted according to the angle of the slope, ensuring that the discharge blade 61 can be stably placed in the ground, thus improving the adaptability and flexibility of the device.
[0034] Workflow: When sowing dryland rice on sloping land, the storage box 1 is fixed to the existing agricultural machinery. The entire machine moves downwards via the machinery control device. When the discharge blade 61 breaks through the soil and extends into the ground, the bottom of the roller 65 contacts the ground. During this process, the sowing assembly 6 moves upwards a certain distance via the stop bar 57, driving the shaft block 56, extension column 55, and spring plate 54. Simultaneously, the spring plate 54 compresses the linear spring 53 to a certain extent. There is still some space between the top of the spring plate 54 and the top of the mounting groove 52, causing the hose 3 to deform. As the entire machine moves, the roller 65 rolls on the ground. When encountering a slope, the two rollers 65 drive the horizontal plate 64 and roller column 62 to rotate to a certain extent, and the discharge blade 61 also rotates to a certain extent. Through the contact between the two rollers 65 and the ground, the horizontal plate 64 is kept relatively parallel to the ground, allowing the discharge blade 61 to adapt to the slope angle and facilitate discharge. The blade 61 can be stably positioned in the ground. When the roller 62 rotates, it drives the spring 63 to generate elastic force. Under the elastic force of the spring 63, the rear end and upper part of the discharge blade 61 can be kept moving towards the stop rod 57. The stop rod 57 limits the rotation angle of the discharge blade 61. At the same time, during the movement of the entire device driven by the agricultural machinery, when passing over a slope, under the elastic force of the linear spring 53, the spring plate 54, the extension column 55 and the shaft block 56 can move downward, thus adapting to the height of the slope. The vibration of the vibration motor 2 causes the dry rice in the storage box 1 to enter the inside of the discharge blade 61 evenly through the hose 3, and then fall into the soil through the discharge blade 61, achieving the sowing effect. Based on the above principles, when sowing on a slope, the device can automatically adjust according to the height and angle of the slope to adapt to the terrain, ensuring that the sown dry rice is of uniform depth, thereby ensuring the germination rate and uniform growth of the dry rice, laying a good foundation for increased yield in the later stage.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
