Description

Technical Field

[0001] The utility model relates to a combined operation machine, and further relates to a soil preparation component for flue-cured tobacco planting. Specifically, it relates to a ridging plow for mid-season tillage of flue-cured tobacco. Background Art

[0002] As is well known, mid-season tillage and ridging are important links in the field management of tobacco leaf production. In mountainous areas of Guizhou, the land is less contiguous and the terrain is mostly uneven, so large agricultural machinery is often not applicable. In recent years, local tobacco farmers have used small micro-tillers for mid-season tillage and ridging operations. However, the effect of mid-season tillage and ridging is not good, and the upper part of the tobacco ridge cannot be ridged, which has become a difficult problem in the field management of tobacco leaf production. By querying the Chinese patent database, there are not many patent applications related to mid-season tillage and ridging machinery. The main ones are CN216721975U "A Tobacco Mid-season Tillage and Ridging Machine" applied by Zhuzhou City Company of Hunan Provincial Tobacco Company and CN211429934U "A Weeding and Ridging Plow Head Structure and Multifunctional Device for Tobacco Cultivation" applied by Zhaotong City Company of Yunnan Provincial Tobacco Company. These patented technologies have their own characteristics, but they cannot be applied to mountainous tobacco fields and cannot solve the ridging problem of mountain tobacco ridges. Summary of the Invention

[0003] The utility model aims to provide a ridging plow for mid-season tillage of flue-cured tobacco, which can effectively improve the weeding, mid-season tillage, and ridging effects of the upper part of the tobacco plant and solve the ridging problem of the upper part of the mountain tobacco ridge.

[0004] The ridging plow for mid-season tillage of flue-cured tobacco provided by the inventor has two sets, which are respectively installed on the rotating shafts on the left and right sides of a small rotary tiller; each set of ridging plows includes a main plow claw and a secondary plow claw; the main plow claw consists of two groups of soil claws in the front and back. Each group has 3 curved soil claws, which are connected to each other by bolts at equal angles (120°) and installed as a whole; the intersection center of the 3 soil claws is a circular space, which is installed on the rotating shaft with nuts; the soil claw of the secondary plow claw is spiral, and this soil claw rotates with the rotation of the rotating shaft to achieve ridging of the tobacco ridge; the main plow claw and the secondary plow claw are connected by a universal joint.

[0005] Each of the 3 soil claw pieces in each group of the above-mentioned main plow claws is bent at one end, and the bending directions are different. One piece is bent to the right, and the other two pieces are bent to the left, and the bending angles are the same; the other end is a flat plate with an arc. The 3 soil claw pieces are connected to each other by bolts, and a circle is formed in the middle and installed on the rotating shaft with nuts to ensure that the soil claws do not loosen or fall off; the 3 soil claw pieces form a group of main plow claws, and there is a distance between the front and back two groups of main plow claws, and they run synchronously.

[0006] The above-mentioned secondary plow claw consists of a central shaft, a spiral blade, a connecting piece, and a connector. The connecting piece and the connector are welded at one end, and the connector is fixed on the rotary tiller frame through a fixing rod, and the spiral blade forms a spiral around the central shaft.

[0007] The above-mentioned small rotary tiller is a commercially available rotary tiller, which includes a frame, rotary tilling wheels and ridging plows; a walking wheel is installed in the middle of the front end of the frame, the width of the walking wheel is less than the width of the ditch between tobacco ridges, the rotary tilling wheels are inclined, the middle of the rotary tilling wheels is tangent to the side of the tobacco ridge, and the outermost side of the mud baffle is close to the bottom of the tobacco plant to prevent mud from pressing on the tobacco leaves.

[0008] For the above-mentioned small rotary tiller, a set of flue-cured tobacco intertillage ridging plows is installed on each of the left and right sides. The two sets are symmetrical to each other and have exactly the same structure.

[0009] The working principle of the flue-cured tobacco intertillage ridging plow of the present invention is as follows: when the rotary tiller moves forward, the main plow claws loosen the soil at the bottom of the tobacco ridge ditch, and then the secondary plow claws that rotate while moving forward rotate the soil to the upper half of the tobacco ridge, completely covering the ridge top. In this way, the entire ridging process is completed at one time, saving time and labor costs. At the same time, due to the use of universal joints, the machine can be adjusted more flexibly and adapted to different terrains and operating conditions, thereby further improving the operation efficiency. The design of the main and secondary plow claws effectively improves the ridging depth and coverage rate, ensuring that the soil is more evenly covered on the ridge surface, which is crucial for tobacco growth.

[0010] The present invention is used for loosening the soil and weeding the tobacco plants on the tobacco ridges and ridging, reducing the labor intensity of the secondary manual operation required for the upper half of the ridge surface after the operation of the previous small micro-tiller. This ridging plow targets the defects of the old plow claws installed on the small micro-tiller in the past, and cleverly processes and modifies the plow claws. A row of spiral plow claws is added by docking with a universal joint, which can effectively improve the weeding, intertillage and ridging effects of tobacco plants and reduce the labor employment. This ridging tool is modified on a small micro-tiller, not restricted by the bulkiness of medium and large machines, nor by geographical conditions. It is simple and safe to operate, flexible in turning around, and suitable for ridging operations of tobacco ridges in tobacco planting. Description of the Drawings

One is bent to the right, and the other two are bent to the left, and the bending angle is 80º; the other end is a flat plate with an arc. The 3 soil claw blades 1 are connected to each other by bolts 2 to ensure that the soil claws are not loose or fall off. A circle is formed in the middle and installed on the rotary tiller shaft 3 with nuts; the 3 soil claw blades 1 form a group of main plow claws; the distance between the two groups of main plow claws is 5 cm and they run synchronously.

The connecting piece 9 and the connector 5 are welded at one end, and the spiral blade 8 forms a spiral around the central axis 7, and the distance of the spiral blade 8 is 5 cm.

[0020] The small rotary tiller is a commercially available rotary tiller of model 173, which includes a frame, rotary tilling wheels and ridging plows; a walking wheel is installed in the middle of the front end of the frame, and the width of the walking wheel is smaller than the width of the ditch between the tobacco ridges. The rotary tilling wheels are inclined, the middle of the rotary tilling wheels is tangent to the side of the tobacco ridge, and the outermost side of the soil baffle is close to the bottom of the tobacco plant to prevent the soil from pressing on the tobacco leaves.

[0021] The ridging plow of the present utility model can be installed not only on the 173-type rotary tiller for use, but also on other types of rotary tillers for use.
