Description

Technical Field

[0001] The utility model relates to the technical field of tobacco field tools, in particular to a sleeve-type tobacco seedling earthing-up device for covering holes with soil. Background Art

[0002] About 25 days after transplanting flue-cured tobacco seedlings into water-created well cellars, when the growth point of the tobacco seedlings exceeds the well cellar opening by 3 cm to 5 cm, it is necessary to fill the well cellar with soil and seal the plastic film opening tightly and firmly. This can not only keep warm and retain soil moisture, but also effectively avoid the growth of weeds. In the past, when covering the holes with soil, the conventional method was for one person to hold the seedlings and another person to shovel soil, and the two worked together to cover the holes with soil. Since the operator needs to keep bending down when holding the seedlings, after a day's work, the operator will have a sore back and the workload is relatively large, and the labor efficiency is not high.

The solution includes a central member, a handle, a pull handle, a transmission rod, a transmission ring, an earthing-up disc and a tension spring. The handle and the pull handle are respectively connected to the central member, and the earthing-up disc is connected to the central member; the tension spring is respectively connected to the central member and the pull handle; the transmission rod includes a primary transmission rod and a secondary transmission rod. The primary transmission rod includes a force rod I, a force rod II and a force rod III. The force rod II is rotatably fixed on the central member, the force rod I is connected to the pull handle, and the force rod I, the force rod II and the force rod III are hinged; an installation disc and a secondary transmission rod are provided on the transmission ring, an installation seat is provided on the installation disc, and the installation seat is hinged to the force rod III; a roller is provided at the bottom of the secondary transmission rod, and a groove is provided on the earthing-up disc. The utility model is mainly used for the work of covering holes with soil for flue-cured tobacco.

[0004] The existing device gradually exposes the deficiencies of the prior art during use, which are mainly manifested in the following aspects:
