Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to a peanut planting spacing control device. Background Technology

[0002] Sowing is typically done in spring when the soil temperature is consistently above 15℃, preferably in loose, well-drained sandy loam soil. Before sowing, the land should be carefully prepared and sufficient base fertilizer applied. The growth cycle is approximately 100-150 days, requiring attention to weeding, pest and disease control, and proper water management. Harvesting is complete when the leaves turn yellow, the stems wither, and the pods have a clear netting pattern. Peanuts are rich in oil and protein, making them both an important oilseed crop and a popular direct food, possessing high economic and nutritional value.

[0003] In actual planting, if peanut plants are planted too close together, they will shade each other, preventing the lower and middle leaves from receiving sufficient sunlight, reducing photosynthetic efficiency and affecting the accumulation of organic matter. In addition, too close spacing will create a humid and closed growing environment, which is a breeding ground for diseases such as leaf spot, rust, and white mold, as well as some pests. Therefore, peanuts need to be planted with good spacing to improve the microclimate in the field and reduce the occurrence and spread of diseases and pests.

[0004] In existing technologies, mechanized precision seeding is an effective measure to achieve uniform spacing. It incorporates a core seed metering device that enables single-seed metering and, through a series of automated operations, dispenses seeds at fixed time intervals, thus creating uniform plant and row spacing on the ridges. However, in practical use, only plots with modern agricultural standards can utilize efficient seeding machinery. Small plots or hilly areas still rely on traditional manual seeding. Furthermore, peanut seeding requires pre-digging holes before inserting the seeds, involving two operational methods, resulting in low efficiency. In summary, there are operational limitations and room for technological improvement. Utility Model Content

[0005] This invention aims to solve the aforementioned technical problems that, for small plots or hilly areas, traditional manual sowing is still relied upon, resulting in low efficiency and limitations in operation and technical improvement. It provides a peanut sowing spacing control device.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a peanut planting spacing control device, including an adjustable column, a handle at the upper end of the column, and a fixing plate at the lower outer side of the column; planting components are movably provided on the fixing plate and on both sides of the column, and the planting components and the fixing plate are adjustable.

[0007] The seeding assembly includes a hollow column with a round hole at the upper end; a recess is provided on the outer side of the hollow column, and a thread is provided in the recess; the fixing plate is provided with a strip groove that can accommodate the hollow column, and locking nuts are threadedly connected to the upper and lower ends of the recess and the strip groove.

A material discharge head is connected to the lower end of the hollow column, and the material discharge head is inverted conical.

[0009] Furthermore, the corners of the handle are all rounded.

[0010] Furthermore, the outer side of each locking nut is provided with anti-slip texture.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example 1, in conjunction with Appendix Figure 1 , 2 3. A peanut planting spacing control device includes an adjustable-length column 1. Specifically, the column 1 includes a base column 8 and an extension column 9 slidably disposed at its upper end. The upper end of the base column 8 is provided with a threaded neck 10, the inner diameter of which gradually decreases and is connected with engaging teeth. An adjusting nut 11 is threadedly connected to the outer side of the threaded neck 10, the inner diameter of which gradually decreases from the middle to the upper end. In actual use, the extension column 9 can move up and down within the base column 8. After determining the height, the adjusting nut 11 is rotated downwards, causing the end with the smaller inner diameter to gradually lock the engaging teeth downwards, thereby locking and fixing the extension column 9. This allows the overall height of the column 1 to be adjusted, facilitating flexible use.

[0026] Based on the above, the upper end of the column 1 is provided with a handle 2. The corners of the handle 2 are all smoothly transitioned, making it easy to apply force and subsequently insert the material feed head 18 into the soil.

[0027] Combined with appendix Figure 1 , 4 5. A fixing plate 3 is provided on the outer side of the lower end of the column 1, and a scale line 12 is provided on the front of the fixing plate 3; the scale line 12 facilitates observation and subsequent adjustment of the spacing of the hollow columns 4;

[0028] Based on the above, a sowing component is movably mounted on the fixing plate 3 on both sides of the column 1, and the sowing component and the fixing plate 3 are adjustable. Specifically, the sowing component includes a hollow column 4, with a round hole 22 at the upper end of the hollow column 4 for inserting peanut seeds; a recess 5 is provided on the outer side of the hollow column 4, and a thread is provided inside the recess 5; the fixing plate 3 is provided with a strip groove 6 that can accommodate the hollow column 4, and locking nuts 7 are threadedly connected to the upper and lower ends of the recess 5 and the strip groove 6, and anti-slip textures are provided on the outer side of the locking nuts 7; by rotating the locking nuts 7, the hollow column 4 can be fixed in the strip groove 6 of the fixing plate 3, and the spacing can be adjusted.

A material discharge hole 15 is provided on the sealing plate 13. A support rod 16 is movable in the middle of the sealing plate 13. A pressure plate is provided on the upper end of the support rod 16 extending out of the hollow column 4. A hollow cylinder 17 that can block the material discharge hole 15 is elastically movable at the lower end of the support rod 16. A material discharge head 18 is connected to the lower end of the hollow column 4. The material discharge head 18 is inverted conical. In use, the spacing of the hollow columns 4 is adjusted. Then, insert the two feed heads 18 into the soil to limit the planting of two adjacent planting pits. At this time, put the seeds into the first round hole 22 so that they fall into the hollow column 4. Then press down the support rod 16 and expose the feed hole 15 of the sealing plate 13. The seeds enter the feed head 18 and are planted directly without digging pits in advance. Then pull out the whole thing and move the lower end of the first hollow column 4 forward into the hole pressed down by the second hollow column 4. Repeat this process to achieve fixed-spacing sowing.

[0030] In addition, a base 19 is provided inside the feeding head 18, and several connecting rods are provided between the base 19 and the lower end of the hollow column 4; a hollow cylinder 20 is provided on the base 19, and a hollow cylinder 17 is located on the outer side of the upper end of the hollow cylinder 20, and a spring 21 is provided between the two; the spring 21 provides elastic force, which can drive the hollow cylinder 17 to move upward from the outer side of the hollow cylinder 20 to achieve reset and block the feeding hole 15.
