Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco seedling transplanting and punching, and in particular relates to a tobacco seedling transplanting and punching tool. Background Art

[0002] Punching and transplanting with the help of punching machinery has become a new model for transplanting tobacco seedlings in wells and cellars in hilly and mountainous areas. The key to promoting well-cellar transplanting technology is the construction of transplanting wells and cellars. At present, the production of wells and cellars with traditional manpower-driven simple punchers is labor-intensive, inefficient, and the labor cost is increasing. Although the introduction of transplanting punchers powered by batteries or small gasoline engines in recent years has improved the punching efficiency, their unreasonable structural design, large terrain differences in mountainous and hilly areas, and large land slopes.

[0003] The existing equipment has poor adaptability during use, resulting in high labor intensity and low work efficiency, which in turn leads to uneven holes and low qualified rate. The holes made by the smooth drill bit have smooth inner walls and high soil hardness, which is not conducive to the subsequent growth of tobacco seedlings. For this reason, an improved tobacco seedling transplanting drilling tool was designed. Utility Model Content

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a tobacco seedling transplanting punching tool to solve the problems in the above-mentioned background technology.

[0007] By adopting the above structural design, the tobacco seedling transplanting and drilling tool is improved by the drill bit design. Specifically, a reaming blade is detachably connected to the rod body of the drill rod near the drill bit tip. The width of the reaming blade gradually decreases from top to bottom, so that the diameter of the hole drilled by the drill rod gradually increases from bottom to top, which can be beneficial to transplanting the tobacco seedlings in the hole and facilitating the subsequent growth of the tobacco seedlings. At the same time, a mud guard is also provided above the reaming blade, which can prevent the splash of soil during drilling to a certain extent.

[0012] Furthermore, the frame includes a bottom plate and a top plate which are arranged in parallel, a column is connected between the bottom plate and the top plate, and a through hole for installing a drill assembly is opened on the bottom plate.

[0013] Furthermore, there are two reaming blades, which are respectively arranged on the front and rear sides of the drill rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The tobacco seedling transplanting and drilling tool is designed by improving the drill bit. Specifically, a hole-reaming blade is detachably connected to the rod body of the drill rod near the drill bit tip. The width of the hole-reaming blade gradually decreases from top to bottom, so that the diameter of the hole drilled by the drill rod gradually increases from bottom to top, which is conducive to transplanting tobacco seedlings in the hole and facilitating the subsequent growth of tobacco seedlings. At the same time, a mud guard is also arranged above the hole-reaming blade, which can prevent the splashing of soil during drilling to a certain extent;

[0016] 2. The blade of the reaming blade is provided with a plurality of notches along its length direction, so that the drill rod drives the reaming blade to rotate to drill holes. The inner diameter of the drilled hole is variable, and the inner wall of the hole is rougher than that of the hole drilled in the prior art, which is conducive to the subsequent growth of tobacco seedlings.
