Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco seedling cultivation, and specifically relates to a tobacco seedling transplanting and soil covering device. Background Art

[0002] Tobacco is an annual herb of the genus Nicotiana in the family Solanaceae. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, gradually pointed at the apex, narrowed at the base to become ear-shaped and semi-amplexicaulous, with inconspicuous petioles or wing-shaped; the inflorescence is conical, the calyx is tubular or tubular-bell-shaped, the lobes are triangular-lanceolate, the corolla is funnel-shaped, light yellow, light green, red or pink, with yellow at the base; the capsule is ovoid or elliptical, almost as long as the persistent calyx; the seeds are round or broadly oblong, brown; the flowering and fruiting period is summer and autumn.

[0003] When transplanting flue-cured tobacco, the seedlings are first placed in the pond, and then covered with soil. When covering the soil, the soil needs to be carefully filled between the seedlings and the wall of the pond. Even if you are careful, it is easy to cover the seedlings with soil, causing the seedlings to bend or other damages. The operator also needs to squat down and pull out the soil covering the seedlings by hand.

[0004] In order to prevent the tobacco seedlings from bending or being damaged, Chinese utility model patent CN220586807U discloses a tobacco seedling transplanting and covering soil device. The protective cover and the soil cover are placed in the pond mouth by holding the handle, and the tobacco seedlings are covered in the protective cover. Soil is filled into the filling space. After the filling is completed, the tobacco seedling transplanting and covering soil device is taken out. The soil will gather around the roots of the tobacco seedlings instead of pressing on the tobacco seedlings, causing no damage to the tobacco seedlings, and there is no need to squat down and remove the soil on the tobacco seedlings. This reduces the labor intensity and improves the efficiency of covering the soil.

[0005] Although the above-mentioned prior art can prevent tobacco seedlings from being broken and damaged during transplantation, since the rhizome lengths of each tobacco seedling are different, the positions of the leaves are also different. Therefore, when facing tobacco seedlings with longer rhizomes, it is easy to have incomplete coverage of the rhizomes of the tobacco seedlings, which in turn leads to insufficient stability during transplantation. Utility Model Content

[0006] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A tobacco seedling transplanting and covering soil device comprises a connecting rod body, a soil cover is arranged on the outside of the connecting rod body, a plurality of sliding grooves are arranged on the outer wall of the connecting rod body, a plurality of sliding plates inserted into the sliding grooves are fixedly connected to the inner wall of the soil cover near the upper end, each sliding plate is slidably connected to the inside of the sliding groove, a plug hole is arranged on the bottom of the connecting rod body, the bottom of the soil cover contacts the ground, and the connecting rod body moves downward so that the blades are located at the plug hole.

[0009] Preferably, a sliding block body is fixedly connected at the intersection of multiple sliding plates, the sliding block body is slidably connected to the inside of the plug-in hole, the bottom of the sliding block body is concave, and a return spring is fixedly connected between the upper end of the sliding block body and the inner top of the plug-in hole, and the elastic force of the return spring causes the soil cover to always move downward.

[0010] Preferably, the upper end of the connecting rod body is provided with a through hole connected to the plug-in hole, the upper end of the sliding block body is fixedly connected with a threaded rod passing through the through hole, the outer wall of the threaded rod is threadedly connected with a hexagonal nut, the end of the threaded rod is fixedly connected with a limiting disk, and the hexagonal nut is rotated to contact the upper end of the connecting rod body to fix the position of the connecting rod body.

[0011] Preferably, the soil enclosure cover is in the shape of a funnel which is wide at the top and narrow at the bottom, and openings are arranged on both the upper and lower sides of the soil enclosure cover.

[0012] Preferably, a filter plate with openings at both ends is installed inside the soil enclosure, and a plurality of filter grooves are provided on the outer wall of the filter plate. The filter grooves filter larger soil blocks and stones and diffuse them around from the through grooves through the outer wall of the filter plate.

[0013] Preferably, the filter disc is funnel-shaped with a narrow upper end and a wide lower end.

[0014] Preferably, handles are fixedly connected to both sides of the outer wall of the connecting rod body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The sliding plate body is connected to the inner sliding groove. When covering with soil, the downward movement of the connecting rod body is adjusted according to the root length of the tobacco seedlings or the position of the leaves, so that the tobacco seedlings are covered in the concave part at the bottom of the sliding block body and the inside of the plug-in hole, thereby protecting the tobacco seedlings with different leaf heights when covering with soil. The through groove can make the excess soil diffuse around, thereby preventing the excess soil from pressing on the tobacco seedlings when the equipment is taken out after covering with soil.

[0017] 2. A reset spring is fixedly connected between the upper end of the sliding block and the inner top of the plug-in hole. The elastic force of the reset spring makes the soil cover always move downward. When covering the soil, the bottom of the soil cover contacts the ground. The leaves of the tobacco seedlings can be located in the concave part of the bottom of the sliding block by holding the through hole and pressing down. The setting of the reset spring makes it easier for the operator to maintain the height.

[0018] 3. By setting the hexagonal nut and threaded rod, when the connecting rod body moves downward, the threaded rod passes through the inside of the through hole. After adjusting the position, the hexagonal nut is rotated to make it contact with the upper end of the connecting rod body, so that the position of the connecting rod body can be fixed. When facing tobacco seedlings with the same leaf height, multiple adjustments are not required, thereby improving the soil covering efficiency.

[0019] 4. Through the filter grooves set on the filter plate, when covering the soil, larger soil blocks and stones are filtered through the filter grooves, and diffused from the through grooves to the surrounding areas through the outer wall of the filter plate, avoiding the mixing of stones inside and causing the roots of the tobacco seedlings to be not stable enough after covering the soil.

After adjusting the position, the hexagonal nut 206 is rotated to make it contact with the upper end of the connecting rod body 100, thereby fixing the position of the connecting rod body 100. When facing tobacco seedlings with the same leaf height, multiple adjustments are not required, thereby improving the soil covering efficiency.

[0035] like Figure 5As shown, it is a schematic diagram of the filter plate structure in this embodiment, a filter plate 208 with openings at both ends is installed inside the soil cover 200, the filter plate 208 is funnel-shaped with a narrow upper end and a wide lower end, and the outer wall of the filter plate 208 is provided with a plurality of filter grooves 209. In this embodiment, when covering the soil, larger soil blocks and stones are filtered through the filter grooves 209, and diffused to the surroundings from the through grooves 202 through the outer wall of the filter plate 208, so as to avoid stones being mixed inside and causing the roots of the tobacco seedlings to be not stable enough after the soil is covered.
