Description

Technical Field

[0001] The utility model relates to the technical field of agricultural weeding, and more specifically, to an automatic screening weeding device for intelligent agricultural machinery. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery. At present, most weeding equipment on the market cannot automatically distinguish between plants and weeds. Excessive weeding by workers will increase damage to plants, which is not conducive to the normal growth of plants. In addition, since the weeding device often removes weeds in the soil, the shovel head needs to be replaced frequently, polished, and replaced with a new shovel head. However, when the weeding shovel head of most equipment needs to be replaced, it is not convenient to disassemble it, which is not conducive to the rapid disassembly and maintenance of the staff. The operation is not convenient, it takes a lot of time, and the installation efficiency is low. For this reason, we have launched the following device. Utility Model Content

This automatic screening weeding device for intelligent agricultural machinery is equipped with a weeding mechanism, an extrusion plate, a circular spring, a motor, a rotating roller and a crushing knife. When people need to remove weeds, they hold the handle to weed. Since the rhizome of the plant is larger than that of the grass, the rhizome of the grass will enter the inside of the shovel head. The rhizome of the grass is tightly fixed by grasping the grass rod. The diversion groove arranged inside the shovel head can divert the soil to avoid clogging the shovel head and affecting the weeding efficiency. Since the rhizome of the plant is thicker, when it enters the storage groove, it passes through the root of the plant The stem squeezes the squeezing plate, and with the cooperation of the third spring, the squeezing plate and the connecting rod, the two sets of circular spring pieces shrink, thereby protecting the roots of the plants in the storage groove.
