Description

Technical Field

[0001] This utility model relates to the field of tobacco planting technology, specifically to an integrated machine for weeding, hilling, and stalk pulling of tobacco leaves. Background Technology

[0002] During the crop growing season, weeds often grow rapidly, and the ridges sink significantly due to erosion. Moreover, if farmland is not cultivated for a long time, the soil will become compacted, affecting crop growth and thus impacting crop yield.

[0003] Chinese Patent No. CN218735846U discloses a hilling and weeding machine, comprising: a hilling machine body with a reducer having one input shaft and two output shafts, the input shaft being drive-connected to the power output end of the hilling machine body, and multiple hilling blades fixed on each of the two output shafts; two conical weeders, each comprising: a connecting shaft, one end of which is fixedly connected to the shaft end of the output shaft; a ring, fixed to the connecting shaft by spokes and arranged near one end of the connecting shaft; a circular plate, one side of which is fixedly connected to the other end of the connecting shaft, the diameter of the circular plate being smaller than the diameter of the ring; and multiple weeding blades, each weeding blade having its two sides fixedly connected to the outer edge of the ring and the outer edge of the circular plate, respectively. This hilling machine can perform hilling and weeding simultaneously, eliminating the need for manual weeding, greatly reducing labor costs and lowering tobacco planting costs.

[0004] However, in the above technical solution, the hilling and weeding work are carried out simultaneously by rotating the hilling knife and the cone-shaped weed cutter. However, the position of the cone-shaped weed cutter cannot be adjusted. In different regions, the spacing of the field ridges in the soil is different. When removing weeds on the field ridges, the cone-shaped weed cutter needs to be in close contact with the field ridges to avoid damaging the field ridges and tobacco. Utility Model Content

By adjusting the horizontal movement of the moving end of the assembly towards each other, the spacing between the weeding blades can be adjusted so that they can be closer to the field ridges for weeding operations. This avoids the decrease in weeding efficiency and damage to the field ridges and tobacco leaves caused by the spacing between different field ridges. Attached Figure Description

[0025] Example 3

[0026] like Figures 2-4 As shown, the integrated tobacco weeding, hilling, and stem pulling machine proposed in this utility model, compared to Embodiment 2, has a more detailed structural adjustment assembly including a sliding rod 12, a fixed seat 13, a movable seat 14, a baffle 15, a rotating rod 16, an adjusting handle 17, a rotating plate 18, a connecting rod 19, and a limiting component. Two sliding rods 12 are arranged in parallel, with fixed seats 13 connected to both ends of each sliding rod 12. The fixed seats 13 are connected to the support frame 1. The movable seat 14 is slidably connected to the sliding rod 12, and the baffle 15 is connected to the movable seat 14. The baffle 15 is connected to...

The mounding blade 4 and the weeding blade 5 on the mounting shaft 3 rotate to contact the soil and weeds respectively, and the rolled-up soil... The soil and grass that are thrown off are blocked by the guide plate 25 to avoid affecting the surrounding crops. In tobacco fields with different planting spacing, personnel can rotate the adjusting handle 17 to drive the rotating rod 16 to rotate. The rotating rod 16 drives the rotating plate 18 to rotate, thereby changing the position of the two connecting rods 19. One end of the connecting rod 19 is restricted by the baffle 15, thereby driving the baffle 15 and the moving seat 14 to move linearly along the sliding rod 12. The baffle 15 drives the mounting tube 9 to move along the mounting shaft 3 to adjust the spacing between the weeding blades 5, so that it can adapt to the different spacing of the ridges.
