Description

Ditching wide narrow row adjustable press roller structure Technical Field The utility model belongs to the technical field of compacting rollers, and particularly relates to a ditching wide-narrow row adjustable compacting roller structure. Background At present, the wheat sowing adopts machine operation and manual operation, a disc or a cutting disc furrow opener is adopted for the wheat sowing machine to open furrows, regular furrows are cut in soil, and seeds are ensured to be accurately sowed into preset depth, but the traditional disc or cutting disc furrow opener is used for directly sowing after rotary tillage and soil preparation, the width of sowing cutting slits is not more than 10mm, the seeds are mutually extruded in narrow cutting slits, moisture and nutrient are not uniformly absorbed in a germination period, large-area lighting is not easy in a growth period, soil nutrient is fully absorbed, slow growth and malnutrition are caused, the tillering quantity is reduced, unit yield is relatively low, 2 additional fertilizer is needed in the later period, and the cost is increased. And secondly, the soil is relatively loose after rotary tillage soil preparation is not pressed, and the soil moisture preservation, soil moisture conservation and crop rooting are also not facilitated, the soil is easy to lodge, the unit yield is low, and the management cost is high. Another manual operation, such as a scattered cultivation mode, has the conditions of seed emergence, seed waste and fertilizer waste, and loose soil after rotary cultivation and soil preparation, is unfavorable for the growth of crops, is unfavorable for the soil moisture preservation and moisture preservation of crops, and is not firm in rooting and easy to lodge. Disclosure of Invention The utility model aims to design a ditching wide-narrow row adjustable pressing roller structure, which is used for improving and upgrading a ditching mode of a wheat seeder and realizing the wide-narrow row adjustable ditching. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The ditching wide-narrow row adjustable pressing roller structure is characterized by comprising a pressing roller, wherein two ends of the pressing roller are arranged on a side gear box through bearing blocks, the pressing roller is driven to rotate through a gear set in the side gear box, the pressing roller comprises a pressing ditch pipe, a plurality of fixed ring plates are welded on the surface of the pressing ditch pipe, a plurality of bolt holes are formed in the fixed ring plates, and a ditch wheel is arranged on the fixed ring plates through bolts. Further, the two ends of the ditch pressing pipe are respectively provided with a ditch pressing roller shaft head and a ditch pressing roller spline shaft head, the ditch pressing roller spline shaft head is connected with a driving gear, and the driving gear is meshed with the gear set to realize ditching when the ditch pressing roller rotates. Further, the side gear box comprises a side plate, a gear box plate is arranged on the side plate, a triangle-like gear box is formed between the gear box plate and the side edge through a plurality of complementary plates, and a plurality of spacers are arranged on the triangle-like gear box. Further, holes are arranged at three corners of the triangle-like gearbox. Further, the two ends of the pressing roller are placed into one of the holes of the gear boxes on the two sides. The following beneficial effects can be obtained through the technical scheme: Soil after rotary tillage soil preparation is relatively loose, after the soil is pressed and ditched through the gear-driven pressing roller, the functions of pressing, moisture preservation and soil moisture preservation are achieved, the ditching wide seedling belt is formed at one time, the depth is consistent, the ditch width can be matched with a ditch wheel between 20 mm and 100mm, seeds are dispersed in a ditch seedling bed, the single seeds fully absorb nutrients, the depth is consistent, root seedlings are pricked and are strong, lodging is not easy, the yield per unit is improved by 100 jin to 300 jin compared with the prior art, and the method is very important for stabilizing the yield per unit and improving the yield per unit.
