Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a ridging device and a field structure formed thereby. Background Art

[0002] Timely replenishment of moisture is of great significance to the growth of tobacco. Therefore, a suitable method should be selected to manage the moisture in the field. Generally speaking, the demand for moisture by tobacco is the least in the early and late stages of growth. Therefore, moisture should be concentratedly replenished in the middle stage. Here, the early stage of tobacco growth refers to the stage from the transplanting of tobacco seedlings to the stage of forming a rosette. At this time, only less than 10% of the overall water demand of the tobacco needs to be replenished; the middle stage of growth refers to the stage from the rosette stage of tobacco seedlings to the budding stage. At this time, the water demand is the largest, and about 60% of the overall water volume needs to be replenished; the late stage of growth refers to the late budding stage of tobacco seedlings. At this time, about 30% of the total water volume needs to be replenished.

[0003] At present, the ridging method for tobacco fields can only meet the drainage of tobacco fields and cannot meet the water demand of tobacco in the middle stage of growth. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that, aiming at the fact that the current ridging method for tobacco fields can only meet the drainage of tobacco fields and cannot meet the water demand of tobacco in the middle stage of growth, the utility model provides a ridging device and a field structure formed thereby that can not only meet the drainage of tobacco fields but also realize water storage in tobacco fields and meet the water demand of tobacco in the middle stage of growth.

The ridging tool group includes a soil banking knife 11 and a rotary tillage knife 12. The soil banking knife 11 and the rotary tillage knife 12 in the ridging tool group are respectively installed in a spiral equidistant and staggered manner, and the soil banking knives 11 and the rotary tillage knives 12 on adjacent ridging tool groups are symmetrically arranged, so that the tools on the knife shaft 14 form an effect similar to an auger to push soil towards the center of the ridged body.

[0037] The tool shaft 14 is connected to the driving mechanism through a speed reducer 1. The driving mechanism preferably adopts the output shaft of a tractor.

[0038] The working principle of the present utility model: During operation, first, the first ditch plow 8 and the second ditch plow 9 break the soil layer. The power of the whole device is input from the output shaft of the tractor into the reduction box 1, and then drives the tool shaft 14 to rotate, so that the soil cultivating knives 11 and the rotary tillage knives 12 cut and pile up the soil. Finally, the wide ditch side soil scraping plate 5, the narrow ditch side soil scraping plate 6, and the ridge surface soil scraping plate 4 extrude and form the ridge body. The power transmission of the whole device adopts an intermediate transmission mode. Due to the relative installation of adjacent ridging tool groups, and the soil cultivating knives 11 and the rotary tillage knives 12 of each ridging tool group are installed in a spiral equidistant staggered manner, the tools on the tool shaft 14 form an effect similar to an auger to push the soil towards the center of the ridge body.

The ridge distance of the ridge bodies on both sides of the narrow ditch is designed to be 115 cm, and the ridge distance of the ridge bodies on both sides of the wide ditch is controlled by the tractor driver to be more than 135 cm, so that the width b of the wide ditch can be kept more than 45 cm. After ridging the field, the wide ditches and narrow ditches in the field are all connected to the surrounding ditches to realize the function of field drainage. Since the narrow ditch is 5 cm deeper than the wide ditch and the surrounding ditches, the narrow ditch realizes the function of water storage. In addition, under the condition of the same field area, the ridging method of wide and narrow ditches is more convenient for farmers to walk in the field for field management.
