Description

Weeding device for agricultural planting Technical Field The utility model relates to the technical field of agricultural weeding, in particular to a weeding device for agricultural planting. Background Agriculture belongs to a first industry, and is a basic industry for supporting national economy construction and development, and in the agricultural planting process, weeding work needs to be carried out regularly. The existing agricultural weeding device is easy to damage when a mowing knife encounters hard objects such as stones and the like when the mowing knife is used, meanwhile, operators are easily accidentally injured when the mowing knife is exposed, and the mowing effect is poor. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides a weeding device for agricultural planting, which aims to solve the problems in the background art. The utility model provides a weeding device for agricultural planting, which comprises a base, wherein two sides of the bottom end of the base are fixedly connected with a group of fixed plates, one ends, close to each other, of the fixed plates are respectively and rotatably connected with a limiting ring, the end parts of the limiting rings are fixedly connected with a rotary drum, two sides of the bottom end of the base are respectively and fixedly connected with a supporting plate, the bottom ends of the supporting plates are fixedly connected with limiting columns, the limiting columns are attached to the inner wall of the rotary drum, the outer wall of the rotary drum is provided with a plurality of long grooves, the bottom end of the base is fixedly provided with a motor, the output end of the motor is fixedly connected with a rotating shaft, the outer wall of the rotating shaft is provided with a group of transmission mechanisms, the rotating shaft is synchronously driven by the transmission mechanisms to rotate through a group of rotating rods, two sides of the outer wall of the rotating rods are respectively and fixedly connected with rotating plates, and the upper ends and the lower ends of the rotating plates are respectively and fixedly connected with mowing knives.
