Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a sugar beet planting, fertilization, and soil covering mechanism. Background Technology

[0002] Sugar beets, as an important economic crop, occupy a key position in agricultural planting. Their products are widely used in sugar refining, food processing, and chemical industries. With the acceleration of agricultural modernization, the mechanization of sugar beet cultivation is constantly improving to enhance planting efficiency, reduce labor intensity, and ensure planting quality. In the process of sugar beet cultivation, ditching, fertilization, and covering with soil are crucial steps, and the quality of these steps directly affects the growth and final yield of the sugar beets. Currently, although some agricultural machinery for sugar beet cultivation exists on the market, such as the "fertilization and soil covering mechanism for sugar beet cultivation, comprising: a soil covering component and a second conveying component, wherein the soil covering component is located at the front end of the second conveying component" disclosed in the existing patent with publication number CN214385045U, this mechanism allows the fertilization mechanism to apply fertilizer after the ditching mechanism completes the ditching, and then the soil covering mechanism covers the soil with soil using a soil covering blade, thus realizing the functions of fertilization and soil covering. However, existing equipment of this type has many shortcomings in its structural design:

[0003] Most of the existing soil covering mechanisms mentioned above are designed with a fixed height, which cannot be adapted to different soil covering needs in actual use. During the sugar beet planting process, due to differences in soil texture, climate conditions, and planting density, there are different requirements for the thickness and compaction of the soil covering. Fixed-height soil covering mechanisms cannot meet these diverse needs, resulting in unsatisfactory soil covering effect, which in turn affects the germination rate and growth quality of sugar beets. In addition, the soil covering mechanism in this patent is very difficult to disassemble and repair. Due to the unreasonable structural design and lack of convenient disassembly and assembly structure, when the soil covering mechanism malfunctions or needs maintenance, it requires a lot of time and manpower to disassemble and install. This not only affects the normal use efficiency of agricultural machinery, but also increases maintenance costs. For large-scale sugar beet growers, this is undoubtedly a problem that urgently needs to be solved. Therefore, this utility model proposes a soil covering mechanism for sugar beet planting and fertilization. Utility Model Content

[0024] Please see Figures 1 to 5 This is an embodiment of the present utility model, which provides the following technical solution: a sugar beet planting fertilization and soil covering mechanism, including a fertilization mechanism 2 and a soil covering mechanism installed on agricultural machinery 1, with the fertilization mechanism 2 located on the left side of the soil covering mechanism. In actual operation, the fertilization mechanism 2 and the soil covering mechanism will cooperate with the ditching mechanism on the agricultural machinery 1 itself. After the previous process of ditching is completed, the fertilization mechanism 2 starts to fertilize, and after fertilization, the soil covering mechanism starts to cover the soil. The above structure is all prior art. For the specific structural principle, please refer to the prior patent with publication number CN214385045U. It will not be elaborated here. The structural principle of the ditching mechanism on the agricultural machinery 1 itself has also been fully described in the above prior patent.

[0025] The soil covering mechanism includes a lifting crossbeam 32 set on the top of the agricultural machinery 1, and two lifting support frames 31 detachably connected to the bottom of the lifting crossbeam 32. The bottom ends of the two lifting support frames 31 extend to the bottom of the agricultural machinery 1. A soil covering blade 35 is installed between the bottom ends of the two lifting support frames 31 through a rotating shaft. A soil covering reduction motor 36 is installed on the outer side of the bottom end of one of the lifting support frames 31. The output end of the soil covering reduction motor 36 is connected to the rotating shaft at one end of the soil covering blade 35, so that the soil covering reduction motor 36 can drive the soil covering blade 35 to perform soil covering operation after it is started.

[0026] A height adjustment structure 34 is provided between the lifting beam 32 and the agricultural machinery 1 for subsequent lifting and adjusting of the lifting beam 32, thereby flexibly adjusting the height of the soil covering blade 35.

[0027] A disassembly structure 33 is provided between the lifting beam 32 and the lifting support frame 31 to facilitate the subsequent disassembly of the lifting support frame 31 and the lifting beam 32, thereby facilitating the removal of the soil covering blade 35 and the soil covering reduction motor 36 from the bottom of the agricultural machinery 1 for inspection and maintenance.

[0028] In this embodiment, preferably, the height adjustment structure 34 includes a guide support column 342 welded and fixed to the top surface of the agricultural machinery 1 and located on the left side of the lifting support frame 31; a guide support sleeve 341 welded and fixed to the left surface of the lifting beam 32 and slidably sleeved on the surface of the guide support column 342; an adjusting bolt 343 threadedly connected to the left surface of the guide support sleeve 341; and multiple adjusting screw holes 344 corresponding to the adjusting bolt 343 on the side of the guide support column 342. The threaded end of the adjusting bolt 343 is screwed into one of the adjusting screw holes 344, which can stably limit the guide support sleeve 341, the lifting beam 32, and the lifting support frame 31 to ensure daily... The height of the soil covering blade 35 is highly stable during normal use. When the height of the soil covering blade 35 needs to be adjusted later, simply unscrew the adjusting bolt 343 counterclockwise to release the limit on the guide support sleeve 341. At this time, the lifting beam 32 can be moved up and down, so that the guide support sleeve 341 slides up and down on the surface of the guide support column 342, changing the height of the soil covering blade 35. After adjusting to the appropriate height, screw the threaded end of the adjusting bolt 343 into the adjusting screw hole 344 in another position and tighten it. This completes the quick limit after the height adjustment of the soil covering blade 35, realizing the flexible adjustment of the height of the soil covering blade 35 and meeting the soil covering needs of different sugar beet plantings.

[0029] In this embodiment, preferably, a left threaded hole is provided through the left side surface of the guide sleeve 341, and the left threaded hole matches the threaded end of the adjusting bolt 343, so that the adjusting bolt 343 can be rotated and turned smoothly.

The left end of the limiting block 334 passes through the limiting hole 335. The fixing nut 333 presses and fixes the side base plate 331, realizing a stable connection between the lifting support frame 31 and the lifting beam 32. When subsequent needs To separate the lifting support frame 31 from the lifting crossbeam 32, simply rotate the fixing nut 333 counterclockwise so that the side plate 331 can move to the right, allowing the end of the limiting insert 334 to move out of the limiting insert hole 335, thus removing the limiting effect on the connecting block 311. At this point, the lifting support frame 31 can be moved down, allowing the connecting block 311 to be pulled out from the connecting hole 321. This allows the lifting support frame 31 and the soil covering blade 35 to be quickly removed from the bottom of the agricultural machinery 1 for inspection and maintenance, effectively improving the convenience of subsequent inspection and maintenance of the soil covering mechanism and solving the problem of the soil covering mechanism being difficult to disassemble and repair in the prior art.
