Weeding device capable of weeding among seedlings

Abstract

The invention relates to a weeding device capable of weeding among seedlings, which comprises a frame, a weeding actuating and transmission mechanism arranged on the frame, and a weeding mechanism and wheels which are arranged at the lower part of the frame. The weeding actuating and transmission mechanism is formed in a way that an upper motor on an upper beam of the frame is connected with a planet gear through an upper rear synchronous pulley, an upper synchronous belt and an upper front synchronous pulley in sequence, the planet gear is out-meshed with a sun gear which is fixed at the rear part of the frame; a planet gear shaft and a hole in the front end of a swing arm are concentric in a matching way; a hole in the rear end of the swing arm and the upper rear synchronous pulley are concentric in the matching way; the upper end of a vertical shaft is arranged on a bearing seat at the middle front part of the swing arm through a bearing; the middle lower part of the vertical shaft is connected with a lower front synchronous pulley, and the lower front synchronous pulley is connected with a lower motor through a lower synchronous belt and a lower rear synchronous pulley in sequence; and the lower end of the vertical shaft is connected with an input shaft of the weeding mechanism. The weeding device can effectively weed among the seedlings of crops, and has the advantages of simple structure, flexible operation, convenience in operation and easiness in control.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural weeding device. Background technique [0002] The weeds among the seedlings in the crop planting rows are close to the crops, and directly compete with the crops for water, nutrients and sunlight, seriously affecting the growth of the crops. The bottom of the existing weeding device is close to the ground, and it can only walk between the rows without crops, and then the weeds between the rows can be removed or pulled out through the weeding mechanism at the bottom when walking, so only the weeds between the rows can be removed And can't remove the weeds between the seedlings in the row. The weeds between the seedlings in the crop planting rows are mainly controlled by hand or herbicides. Manual weeding is intensive and inefficient, not only costly, but also likely to cause adverse effects on the health of the staff. Herbicides generally have weed resistance problems,...
