Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural tools, in particular to an auxiliary device for precisely controlling the planting density of flue-cured tobacco. BACKGROUND

[0002] Transplanting is a commonly used planting method. For example, before transplanting tobacco seedlings, a thin film is usually covered on the surface of the soil ridge to preserve the temperature and moisture of the soil ridge. When transplanting the tobacco seedlings, the thin film needs to be broken first, and then the tobacco seedlings are planted in the soil ridge. In order to ensure the normal growth of the tobacco seedlings, there are strict requirements for the planting row spacing and the plant spacing between adjacent two tobacco seedlings during transplanting.

[0003] Due to the complex terrain in mountainous areas, the transplanting of crops mainly relies on manual operation. Manual film breaking not only has high labor intensity, but also is difficult to maintain consistent film breaking spacing, which may affect the growth of the seedlings. In addition, due to the irregularity of the tobacco field plots in the mountainous areas, the ridge length is inconsistent, which makes it difficult to accurately measure per mu, and affects the subsequent planting planning. CONTENT OF THE INVENTION

The device can break the film at a fixed point according to the requirements, reduce the labor intensity, maintain consistent plant spacing of the crops, ensure appropriate planting density, and thus ensure the normal growth of the crops.

[0011] Optionally, in some embodiments, mounting holes are uniformly arranged on the arc-shaped elastic sheets, and the overlapping portions between the two arc-shaped elastic sheets are connected by the first fixing bolt and the second fixing bolt.

[0027] Reference Figs. 1-3 An auxiliary device for accurately controlling the planting density of flue-cured tobacco, comprising:

[0028] The distance wheel 1 is composed of two arc-shaped elastic sheets 11 with the same arc, which are arranged in a central symmetry to form a complete circular structure for convenient use. The mounting holes 12 are uniformly arranged on the arc-shaped elastic sheets 11 to facilitate the adjustment and fixation of the wheel diameter of the distance wheel 1. The connecting plates 13 are arranged on the end of the arc-shaped elastic sheet 11 along the radial direction, and the first U-shaped holes 14 are formed in the connecting plates 13.

[0029] The support 2 is installed between the two connecting plates 13, and the support 2 is adjustably connected with the connecting plates 13. The specific mode is that the second U-shaped holes 22 corresponding to the first U-shaped holes 14 are formed on both sides of the support 2. After aligning the support 2 with the connecting plates 13, the wheel diameter of the distance wheel 1 can be adjusted by sliding the connecting plates 13. After adjusting to the required position, the third fixing bolt 23 is tightened to fix it. Further, in order to ensure the stability of the distance wheel 1, the first fixing bolt 15 and the second fixing bolt 17 are also connected at the position where the two arc-shaped elastic sheets 11 overlap each other.

[0030] The operating rod 3 is rotatably installed at the connecting ring 21 located at the center of the distance wheel 1, so that the distance wheel 1 can rotate uniformly around the connecting position.

[0031] The membrane breaking cone 16 is installed on the distance wheel 1. If multiple membrane breaking cones 16 are needed, they should be uniformly installed on the wheel surface of the distance wheel 1. In this embodiment, two membrane breaking cones 16 are provided. When installing, the included angle between the two membrane breaking cones 16 should be 180°. Similarly, if there are three membrane breaking cones 16, the angle between adjacent membrane breaking cones 16 should be 120°. Further, in order to simplify the structure, the membrane breaking cone 16 is directly arranged on the first fixing bolt 15 in this embodiment. In this way, the first fixing bolt 15 can achieve the membrane breaking effect while fixing the arc-shaped elastic sheet 11.

[0032] The film is opened on the mulch by the film breaking cone 16 to mark the transplanting position, ensure the uniformity of the plant spacing between the transplanted plants, and thus ensure the appropriate planting density. Taking tobacco seedlings as an example, the advantages brought by the precise control of the planting density are three: first, by precisely controlling the planting density, the planting density is avoided to be too high or too low, the tobacco plants are evenly distributed in the field, have suitable growth space, can ensure the number of plants per mu, and effectively improve the tobacco yield; second, by precisely controlling the planting density, the ventilation and light transmission and photosynthesis are enhanced, which helps to improve the uniformity of the tobacco plant growth, makes the maturity of the tobacco leaves more consistent when mature, facilitates the unified picking and curing, is beneficial to improve the quality stability of the cured tobacco leaves, reduces the differences in the quality of the tobacco leaves caused by the inconsistent maturity, and can effectively improve the quality of the tobacco leaves; third, by precisely controlling the planting density, the production potential of the land and the tobacco plants can be fully utilized, the yield is stabilized while the quality of the tobacco leaves is ensured, and the tobacco farmers can obtain more stable income.

[0033] In some embodiments, for the convenience of counting the number of film breaking, a counter 4 is fixedly installed at the end of the operating rod 3. The counter 4 adopts a mechanical counter, and a counting rod 41 is arranged on the side surface of the counter 4. One count is performed by once rotating the counting rod 41. It should be noted that the counter 4 is prior art, and its structure and principle will not be described herein. A lever 24 corresponding to the counting rod 41 is fixedly connected to the support 2. The lever 24 is provided with at least one group, and the number of the levers 24 is consistent with the number of the film breaking cones 16. In this embodiment, two levers 24 are provided, and the included angle between the levers 24 is the same as the included angle between the film breaking cones 16, which is 180°. When the distance wheel 1 rotates, the lever 24 is driven to rotate together, and the position of the counter 4 is relatively fixed. In the process of rotating the lever 24, the counting rod 41 is rotated, so that the number of film breaking is counted. Since the planting row spacing and plant spacing of the plants are strictly limited, the planting number per mu can be calculated by counting the planting number, which is convenient for subsequent planting planning.

[0034] Specific working process:

[0035] According to the requirements, the diameter of the distance wheel 1 is adjusted and fixed. The distance wheel 1 is rotated, and one of the levers 24 contacts the counting rod 41. When the lever 24 rotates one circle, the counting rod 41 is rotated once, which improves the accuracy of counting. The distance wheel 1 is placed on the mulch, and the distance wheel 1 is pushed along the soil ridge by holding the operating rod 3. In this process, the distance wheel 1 rotates continuously, and the film breaking cone 16 on the distance wheel 1 breaks the film every fixed distance, thereby marking the transplanting point, which is convenient for subsequent plant transplanting. After use, the total number of film breaking can be known by observing the counter 4.
