Description

A field weeding device

Technical field

The utility model relates to the technical field of weeding devices, specifically a field weeding device.

Background technique

Weeds refer to plants that grow in places that are harmful to human survival and activities. They are generally uncultivated wild plants or plants that are not harmful to humans. The broad definition of weeds refers to plants that grow in places that are harmful to human activities or harmful to production. All plants on the site are mainly herbaceous plants, including some small shrubs, ferns and algae. The emergence of weeds in the fields is undoubtedly a headache for agricultural workers. If the number of weeds in the fields is not effectively controlled, There may be grass shortages. A large number of weeds grow in the fields, absorbing nutrients from the soil in the fields, reducing the soil fertility of the fields, seriously affecting the normal growth of crops in the fields, resulting in reduced or even no harvests.

For example, a Chinese patent discloses "a new field weeding device" (Patent No.: 201720706496.3). The patent has a simple structure, easy operation, and low production cost.
