A Soil-covering Roller Mechanism with Stepless Adjustable Angle in Paddy Slab Stubble Field

Abstract

The invention discloses an earthing press wheel mechanism steplessly adjustable in rice growing stubble field angle. The earthing press wheel mechanism comprises earthing press wheels, a height adjusting device, a pressure control spring device and a soil scraping device, wherein the earthing press wheels are in shapes of circular truncated cones, the diameter of the inner side face of each earthing press wheel is smaller than the diameter of the outer side face of each earthing press wheel so that the earthing press wheels can easily enter soil, the earthing press wheels are rotatably arranged on shafts, and one end of each shaft is spherical, forms a spherical hinge with a fixing seat and can freely rotate in the fixing seat. When the included angle formed by the two earthing press wheels is needed to be adjusted, each shaft is adjusted to be at a set angle, and the spherical end of each shaft is fixed in the fixing seat formed by two symmetrical sleeve blocks. The earthing press wheel mechanism has the advantages of easily adjusting the angle formed by the earthing press wheels and being simple in structure and suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a soil-covering and pressing wheel mechanism with a steplessly adjustable angle in a paddy stubble field. Background technique [0002] The protective tillage mode of alternating planting between rows with stubble is a sustainable soil tillage measure. The specific implementation method is to end the autumn harvest in the first year, leave high stubble on the surface, and do not prepare the land in the spring of the second year. The operation of sowing, fertilization, and suppression is completed at one time between the rows of stubble, and high stubble is left after harvest in autumn. In the spring of the third year, the soil is not prepared, and the stubble is left directly in the second year, and the root stubble is left for the winter, which is conducive to maintaining the soil aggregate structure and avoiding soil erosion and land desertification. ...

Problems solved by technology

In the rice-rape rotation area in the south, it is necessary to adopt the seedling cultivation and transplanting planting method. Considering the labor intensity and low production efficiency of manual transplanting of rapeseed, it is generally used to cover the ditch and cover the soil with a soil-pressing turbine.

Due to the heavy soil in some areas of the rice slab stubble field, the angle of the soil-covering and pressing turbine is fixed. During the work process, it moves according to the fixed angle. For areas with heavy soil, the angle of the covering and pressing turbine cannot be adjusted at any time for covering and pressing, which is not conducive to Seedling planting
