Description

Technical Field

[0001] The invention relates to the technical field of cotton stalk pulling machines, in particular to a cotton stalk pulling machine. Background Art

[0002] Cotton growth requires water and nutrients, which are primarily obtained from the soil through its roots. The required temperature and air are also partially taken from the soil. Cotton also requires mechanical support from the soil to grow. Cotton stalks are the remaining stalks of cotton plants after they are harvested. They are typically 1-2 meters tall, with roots deep in the soil, and possess strong toughness and tensile strength. In agricultural production, cotton stalks must be cleaned promptly after harvest for the following reasons:

[0003] Land reclamation needs: Cotton stalk residues will hinder the subsequent sowing of crops, especially during mechanized sowing, as cotton stalks can easily entangle agricultural machinery, resulting in reduced efficiency or even equipment damage.

[0004] Pest and disease control: If cotton stalks remain in the field for a long time, they may become overwintering hosts for pests such as cotton bollworms and red spiders, increasing the risk of pests and diseases in the following year.

[0005] Resource utilization: Cotton stalks can be used as biomass fuel, papermaking raw materials or organic fertilizer raw materials, but their collection efficiency directly affects the economic efficiency of resource utilization.

[0006] Traditional cotton stalk pulling relies heavily on manual labor or simple mechanization, a method characterized by low efficiency, high labor intensity, and a high number of residual roots. Furthermore, existing cotton stalk pulling equipment often uses mechanical rotary blades for cutting. While partially mechanized, this lacks precise control over stalk capture and transport, leading to incomplete removal or stalk breakage (only the above-ground portion is removed, with the roots remaining in the soil). This is particularly costly in large-scale planting areas and makes it difficult to meet farming time constraints. Summary of the Invention

On the top, the driven shaft 34 corresponds to the driving shaft 31 one by one, the driving gear 35 includes three groups, and each group of driving gears 35 includes two, the two driving gears 35 of each group are respectively mounted on the outer walls of the driving shaft 31 and the driven shaft 34, and the two driving gears 35 are meshed with each other, the roller member 36 corresponds to the driving gear 35 one by one, the roller member 36 is arranged on one side of the bottom box 2, the roller member 36 is hinged to the outer wall of the other end of the driven shaft 34 and the driving shaft 31, the roller fine-tuning assembly 37 is arranged on the outer wall of the roller member 36, and the roller fine-tuning assembly 37 is located below the shovel plate 1.

[0046] In this embodiment, in the cotton collecting rod mechanism 3, three groups of driving shafts 31 and driven shafts 34 are engaged through two driving gears 35, and cooperate with the precise drive of the first servo motor 33. The first servo motor 33 can synchronously drive multiple groups of roller parts 36 to rotate, and the rotation directions of the two cotton stalk rollers 361 in each group of roller parts 36 are opposite, which can continuously pull the roots of the cotton stalks out of the soil, not only reducing the residual rate of the root system, but also avoiding the problem of cotton stalk breakage caused by the cutting method used in traditional equipment.

[0047] Reference Figure 6-Figure 7 The chain transmission assembly 32 includes a sprocket 321 and a chain 322 , wherein the sprocket 321 is mounted on the outer wall of one end of the driving shaft 31 , and the chain 322 is engaged with the outer wall of the sprocket 321 .

[0048] Reference Figure 8 The roller component 36 includes a cotton stalk lifting roller 361, a docking sleeve 362 and a cone head 363, wherein the cotton stalk lifting roller 361 is hinged to the outer wall of the other end of the driving shaft 31 and the driven shaft 34, the docking sleeve 362 is welded to the outer wall of one end of the cotton stalk lifting roller 361, and the cone head 363 is fixedly connected to the inner wall of the docking sleeve 362 through an axle pin.

[0049] The first servo motor 33 drives the three groups of driving shafts 31 to rotate synchronously through the sprocket 321 and the chain 322. The driven shaft 34 rotates in the opposite direction under the engagement of the driving gear 35. The rotation directions of the two roller members 36 in each group are opposite. As the machine moves, the cotton stalks can be continuously transferred between the two roller members 36, and then the cotton stalks are continuously pulled out of the soil through the rotation of the cotton stalk lifting roller 361 and the cone head 363.

[0050] Example 3, refer to Figure 5 、 Figures 8-10 The roller fine-tuning assembly 37 includes a sleeve 371, a vertical connecting shaft 372, an arc-shaped groove plate 373, a transverse connecting shaft 374 and a transverse fixed shaft 375, wherein the sleeve 371 is rotatably connected to the outer wall of the docking sleeve 362, the vertical connecting shaft 372 is rotatably connected to the top outer wall of the sleeve 371, the arc-shaped groove plate 373 is welded to the bottom outer wall of the shovel plate 1, and the vertical connecting shaft 372 is slidably connected to the inner wall of the arc-shaped groove plate 373, the transverse connecting shaft 374 is rotatably connected to one side outer wall of the sleeve 371, and the transverse fixed shaft 375 is hinged to the outer wall of one end of the transverse connecting shaft 374.

The outer walls of both ends of the transverse fixed shaft 375 are screwed with nuts, and the nuts are tightly attached to the outer wall of the connecting plate 9.

[0051] As the sleeve 371 rotates along the docking sleeve 362, the vertical connecting shaft 372 slides in the arc-shaped groove plate 373. The spacing between the transverse fixed shaft 375 and the sleeve 371 is adjusted by adjusting the position of the nut. Then, through the linkage cooperation between the transverse connecting shaft 374 and the transverse fixed shaft 375, the angle between the two roller parts 36 can be adjusted to ensure balanced pulling force.

[0052] In this embodiment, in the roller fine-tuning assembly 37, the arc-shaped groove plate 373 and the vertical connecting shaft 372 are slidably fitted together. Since the roller member 36 is hinged to the driven shaft 34 and the driving shaft 31, the distance between the horizontal fixed shaft 375 and the sleeve 371 can be adjusted by adjusting the position of the two nuts, thereby adjusting the inclination angle of the roller member 36, which helps to adapt the equipment to environments with different soil hardness or cotton stalk distribution density and reduce the risk of jamming.

[0054] When the hydraulic cylinder 61 is extended and retracted to push the relative position of the bottom box 2 and the tractor front baffle 7, the telescopic rod 62 will slide in the telescopic tube 63 to adjust the angle of the shovel plate 1 to adapt to operations on slopes or soft soil.

[0055] Reference Figure 6 The inner wall of the bottom of the bottom box 2 is fixedly connected to the gear box 8 with equal distances distributed by screws, and the driving shaft 31 and the driven shaft 34 are rotatably connected to the inner wall of the gear box 8 through bearings. The driving gear 35 is arranged inside the gear box 8. The outer wall of one side of the bottom box 2 is fixedly connected to the motor frame 10 by screws, and the first servo motor 33 is fixedly connected to the outer wall of one side of the motor frame 10 by screws.

[0056] Reference Figure 4 A bucket 11 is welded to the outer wall on the other side of the shovel plate 1, and side baffles 12 are welded on both sides of the top outer wall of the shovel plate 1. The outer wall on the other side of the shovel plate 1 is provided with guide openings 13 distributed at equal distances, and the guide openings 13 are located above the roller member 36. A cotton collecting rod opening 14 is provided on the top outer wall of the shovel plate 1 between the two cotton discharge rod mechanisms 5.

[0057] The bucket 11 can guide the cotton stalks to be pulled out to between the two roller members 36, the side baffle 12 can prevent the pulled out cotton stalks from scattering sideways, and the guide port 13 is used to guide the cotton stalks into the active area of the roller member 36. The cotton stalk collecting port 14 is located between the two rows of cotton stalk mechanisms 5, and the cotton stalks are concentrated and output from here.

[0058] Working principle:

[0059] Equipment connection and preparation: Connect the equipment to the tractor through the tractor front baffle 7, adjust the shovel 1 to a suitable inclination angle through the hydraulic cylinder 61, and drive the entire equipment to move through the tractor.

[0060] Cotton stalk pulling out stage: the first servo motor 33 is started, driving the active shaft 31 and the driven shaft 34 to drive the roller member 36 to rotate. As the shovel plate 1 moves, the bucket 11 can get close to the cotton stalk and guide the cotton stalk to be pulled out between the two roller members 36. Since the rotation directions of the two roller members 36 in each group are opposite, the cotton stalks are continuously pulled out from the soil through the rotation of the cotton stalk roller 361 and the cone head 363.

[0061] Cotton stalk conveying stage: the pulled out cotton stalks move up to the top of the shovel plate 1 through the guide port 13 and close to the cotton discharge rod mechanism 5. At this time, the cotton stalk traction head 523 on the transmission belt 521 is responsible for pulling the cotton stalks and transferring them along the pulley 522 to the cotton collection rod port 14 to complete centralized stacking.
