Description

Technical Field

[0001] The utility model relates to an adjustable soil covering disc support, belonging to the technical field of agricultural equipment. Background Technique

[0002] For seeders or ridgers on the market, soil covering discs are often required to backfill and cover the seed furrows or ridges. Generally, disc soil covering discs are used, and when installing the disc soil covering discs, soil covering disc supports are needed for installation and use.

[0003] Publication No.: CN212588828U mentions a soil covering device for a corn seeder, which is provided with two sets of soil covering discs. The auxiliary soil covering disc with a smaller size and a higher position is located at the front, and the main soil covering disc with a larger size and a lower position is located at the rear. When covering the soil after sowing, the auxiliary soil covering disc first scrapes the soil at the higher positions on both sides of the seed furrow, and then the main soil covering disc located at the rear spins up the remaining soil and covers it on the seeds. However, the two sets of soil covering disc structures in this device are simple and have single functions. After covering the soil for the seeds, it cannot compact the covered soil and cannot make the seeds closely combine with the soil. Now, an adjustable soil covering disc support is urgently needed to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an adjustable soil covering disc support to solve the problems raised in the above background technique. The utility model designs a soil covering and adjustable compaction structure, which can then cover and compact the soil and enable the seeds to closely combine with the soil.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: An adjustable soil covering disc support includes a metal support main body, soil covering discs, hollow fixed sleeves, and compaction rollers. There are two soil covering discs, and the two soil covering discs are symmetrically located at the left and right ends of the metal support main body. Small flanges are fixed to the relative inner ends of the two soil covering discs through bolts. Fixed outer collar rings are fixed to the relative inner sides of the two small flanges. Ball bearings are installed in both of the two fixed outer collar rings. Threaded rods are movably installed in both of the two ball bearings. The front side of the upper end of the metal support main body is installed with a hollow fixed sleeve through a bolt. An adjusting rod is longitudinally installed in the hollow fixed sleeve through a butterfly bolt. A damping shock absorber is installed at the lower end of the adjusting rod. A spring is arranged outside the damping shock absorber. A support is installed at the lower end of the damping shock absorber. Bearing seats are longitudinally fixed to the left and right sides of the lower end of the support. Connecting shafts are movably installed in both of the two bearing seats. The compaction roller is horizontally fixed between the two connecting shafts.

[0006] Furthermore, a welding ear plate is obliquely installed at the rear end of the metal support main body.

[0007] Further, the other ends of the two threaded rods are symmetrically installed at the left and right ends of the metal bracket body through nuts.

[0008] Further, a plurality of positioning holes are provided at the front end of the adjusting rod.

[0009] Further, the compaction roller is located in front of the two soil covering discs.

[0010] Further, the surface of the compaction roller is coated with paint.

[0011] Advantages of the present utility model: An adjustable soil covering disc bracket of the present utility model. Due to the addition of a metal bracket body, nuts, threaded rods, ball bearings, fixed outer collar rings, small flanges, hollow fixed sleeves, butterfly bolts, adjusting rods, damping shock absorbers, springs, connecting shafts and compaction rollers in the present utility model, through our design improvement and actual use, it shows that the device has a reasonable structure and good practicability. A soil covering and adjustable compaction structure is designed, and then the soil can be covered and compacted, enabling the seeds to be closely combined with the soil, and the compaction degree is adjustable to maintain the soil moisture, facilitating the seeds to absorb moisture from the soil and germinate. It can also prevent the fine soil covered from being washed away by water or washed open during watering, resulting in the exposure of the seeds and affecting germination.

Detailed Embodiment

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0018] Please refer to Figures 1 - 3 The present utility model provides a technical solution: an adjustable soil covering disc support, which includes a metal support main body 2, soil covering discs 8, hollow fixing sleeves 9, and compaction rollers 18. There are two soil covering discs 8, which are symmetrically located at the left and right ends of the metal support main body 2. Small flanges 7 are fixed to the relative inner ends of the two soil covering discs 8 by bolts. Fixed outer collar rings 6 are fixed to the relative inner sides of the two small flanges 7. Ball bearings 5 are installed in both of the two fixed outer collar rings 6. Threaded rods 4 are movably installed in both of the two ball bearings 5. A hollow fixing sleeve 9 is installed through the front side of the upper end of the metal support main body 2 by bolts. An adjusting rod 11 is longitudinally installed in the hollow fixing sleeve 9 by a wing bolt 10. A damping shock absorber 13 is installed at the lower end of the adjusting rod 11. A spring 14 is arranged outside the damping shock absorber 13. A support 15 is installed at the lower end of the damping shock absorber 13. Bearing seats 16 are longitudinally fixed to the left and right sides of the lower end of the support 15. Connecting shafts 17 are movably installed in both of the two bearing seats 16. The compaction roller 18 is horizontally fixed between the two connecting shafts 17. This design solves the problem that the original device has a single function. After the soil covering for the seeds is completed, the covered soil cannot be compacted, and the seeds cannot be closely combined with the soil.

[0019] As the first embodiment of the present utility model: Welding ear plates 1 are obliquely installed at the rear end of the metal support main body 2. The other ends of the two threaded rods 4 are symmetrically installed at the left and right ends of the metal support main body 2 by nuts 3. By adding the other ends of the two threaded rods 4 symmetrically installed at the left and right ends of the metal support main body 2 by nuts 3, the installation of the two soil covering discs 8 is facilitated. A plurality of positioning holes 12 are formed at the front end of the adjusting rod 11. By adding the plurality of positioning holes 12, the insertion of the wing bolt 10 is facilitated. The compaction roller 18 is located in front of the two soil covering discs 8. By adding the compaction roller 18, the covered soil can be compacted. The surface of the compaction roller 18 is coated with paint.

[0020] As the second embodiment of the present utility model: During actual use, according to the compaction requirement, adjust the depth of the adjusting rod 11 inserted into the hollow fixing sleeve 9, and the horizontal height of the compaction roller 18 can be changed. Then insert the wing bolt 10 into the positioning hole 12 at the corresponding position to fix the horizontal height of the compaction roller 18. Connect the welding ear plate 1 to an external agricultural device through a pin. When the present device is driven to move backward for soil covering, the two soil covering discs 8 come into contact with the external ground and are driven to move backward, and the soil on both sides can be pushed inward to achieve the soil covering operation (note: the soil covering disc 8 is an existing mature technology, and its working principle will not be elaborated, and the height of the covered soil is higher than the lower horizontal cross-section of the compaction roller 18). Then the lower end of the compaction roller 18 comes into contact with the covered soil, and it can be compacted, enabling the seeds to be closely combined with the soil to retain soil moisture and facilitating the seeds to absorb moisture from the soil for germination.
