Traction-type continuous punching and surface profiling leveling device for transplanting work

Abstract

The invention discloses a traction-type continuous punching and surface profiling leveling device. The device comprises a two roller support frames provided with pillow block bearings, a plurality of punching circular pipes and a leveling roller provided with connection shafts at the two ends; the connection shaft at two ends are respectively arranged in the two pillow block bearings, the plurality of punching circular pipes are arranged in multi-head spiral linear distribution in the leveling roller, wherein a notch of each punching circular pipe is an angular cut, and the angular cut surfaces of the plurality of punching circular pipes are in the same direction. The punching circular pipes in the invention are distributed on the leveling roller according to the multiple spiral patterns; in the punching process, at least two punching circular pipes are inserted into the soil, and the punching circular pipes in left and right symmetrical position penetrate into the soil simultaneously, so as to effectively reduce the shock load and the vibration caused by uneven stress on the punching device from the left and right during the penetration of the punching circular pipes into the soil.

Description

technical field [0001] The invention relates to the technical field of crop transplanting, in particular to a traction-type continuous drilling and surface profiling leveling device for transplanting operations. Background technique [0002] The Yangtze River Basin in my country mainly grows winter rapeseed, which is generally grown first and then transplanted. Because the previous crop is rice, the soil is heavy and the mechanized transplanting operation is limited. Therefore, 70% of rapeseed is planted by manual transplanting, but this is labor-intensive. , the efficiency is low, and when manual transplanting, the digging depth is different, the row spacing and plant spacing are not uniform, walking on the plowed field surface will cause uneven surface, easy to accumulate water after rain, and transplanted rape seedlings will be stained damage, reducing the seedling rate. Contents of the invention [0003] The object of the present invention is to provide a traction-type ...
