Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment manufacturing, in particular to a tobacco seedling ridge punching device. Background Art

[0002] During the tobacco seedling planting process, it is necessary to plant tobacco seedlings at a certain distance on the cultivated ridges. However, in terms of the control of the tobacco seedling pits, the traditional method is to dig manually with a hoe, which is not only inefficient, but also cannot control the depth of the holes well, affecting the survival rate of the tobacco seedlings. Most of the existing tobacco seedling ridge drilling machinery and equipment are at the front end of the machine, and the hole punching head is vertically arranged along the travel direction of the machine, and holes are punched on multiple ridges at the same time. For example, application number CN218183936U discloses a tobacco double-ridge hole punching machine, that is, two hole punching heads at the front end of the machine are used to complete the hole punching operation of two ridges at the same time. Such a setting method requires that the tobacco seedling ridge plots are square and the spacing between each ridge is fixed and consistent. However, in reality, the tobacco seedling ridges are unlikely to be square and the spacing between each ridge is fixed and consistent, which will result in the hole punching position on the ridge being incorrect and not meeting the expected hole punching position, thereby affecting the quality of tobacco leaves.
