Description

Technical Field

[0001] The invention relates to the technical field of vegetable planting, in particular to a sowing and covering device for vegetable planting. Background Art

[0002] In the process of vegetable planting, sowing is a key link that determines the subsequent growth trend. Its efficiency and quality directly affect the planting income. Traditional vegetable sowing mostly relies on manual operation. Planters need to manually dig holes and sow seeds, and then cover the soil separately. In some cases, additional watering is required. The whole process is cumbersome, time-consuming and labor-intensive. Especially when planting on a large scale, the manual labor intensity is extremely high and the work efficiency is low, which can hardly meet the needs of modern agricultural production.

[0003] The patent application with application number CN201810027082.7 discloses a sowing and covering device for vegetable planting, including a seed box, a water tank, a rotating disk, a covering disk and a covering plate. The present invention provides a seed box and a water tank so that watering can be done in time after sowing. After sowing, the rotation of the rotating disk causes the third movable groove to drive the connecting column to move outward, thereby opening the covering plate outward, and the covering plate and the rotating disk are moved downward to close to the ground through the rotating cylinder and the screw, and then the rotating disk is rotated in the opposite direction. The covering plate returns to its original position under the action of the third movable groove and the spring, and at the same time, the surrounding soil is moved inward through the scraper plate to cover the seeds, completing the covering process. The device integrates the functions of sowing, watering and covering, reduces the manual operation of workers, improves work efficiency, and has a simple structure and is easy to use.

[0004] In actual applications, existing equipment uses an overly simple soil covering method, which leads to incomplete soil breaking and large soil clods during vegetable planting, which in turn affects the subsequent germination and soil breaking of vegetable seeds, is not conducive to improving the survival rate of vegetable seeds, and also hinders the healthy growth of seedlings, making it difficult to meet the requirements of modern agricultural production for planting efficiency and crop quality.

[0027] Example two: please refer to Figures 6-11On the basis of the first embodiment, the present invention provides a technical solution: in order to improve the soil breaking quality and soil covering effect of the equipment, an internal component 21, a rolling component 22 and a soil breaking component 23 are set.

The bottom of the connecting plate 216 is fixedly connected to a slide plate 217. The inner wall of the slide plate 217 is movably connected to the eccentric column 214. A right-angle plate 1 218 is provided on both sides of the slide plate 217. The tops of the two right-angle plates 1 218 are fixedly connected to the bottom of the connecting plate 216.

The hydraulic rod 222 is driven by the hydraulic energy to produce a telescopic action, thereby pushing the right-angle plate 223 to move. The sliding columns 224 on both sides of the right-angle plate 223 are used to limit the movement trajectory of the right-angle plate 223 so that it maintains a stable linear reciprocating motion.
