Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse breeding and weeding, in particular to an indoor weeding device for a greenhouse. Background Art

[0002] Since the plant breeding greenhouse is an enclosed space, in spring and summer, the weather is sometimes sunny and sometimes rainy, and alternately dry and wet. This microclimate is conducive to the growth of weeds, and weeds can provide a place for pests and pathogens to overwinter. The weeds outside the greenhouse may become the first target of infection by pests and pathogens. Pests and pathogens overwinter on the weeds outside the greenhouse, and may then fly back to the greenhouse to harm crops.

[0003] When dealing with weeds, a weeding device is often used. The general method is to cut the grass leaves and stems through a rotating blade or sickle to achieve the purpose of weeding. At present, in the process of use, the inventor believes that there are two types of weeding equipment commonly used. One is a handheld pole weeder, which directly drives the blade to move through the handle to achieve mowing. The disadvantage is that the hand needs to support the whole process, which is more laborious. The other is a weeder with a movable bracket at the bottom, which can drag the blade and the handle. However, when this type of weeder is used, due to the uneven grass, there are often potholes. The blade height of the weeder is difficult to adjust to harvest from the roots of the weeds, which affects the weeding effect. At the same time, it is difficult to provide anti-touch protection when the blade is not in use, and it is easy to cause accidental injuries due to touch. Utility Model Content
