Description

Technical Field

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

[0002] Cotton growth and development require water and nutrients, which are mainly obtained from the soil through the roots. The required temperature and air are partially taken from the soil, and at the same time, it needs the mechanical support of the soil to grow. The cotton stalk is the remaining stem part of the cotton plant after cotton picking, and its height can usually reach 1-2 meters. The root penetrates deep into the soil and has strong toughness and tensile strength. In agricultural production, after cotton harvesting, it is necessary to clean up the cotton stalks in time. The main reasons include: Land reclamation requirement: The residual cotton stalks will hinder the sowing of subsequent crops. Especially during mechanized sowing, the cotton stalks are easy to entangle agricultural implements, resulting in reduced efficiency or even equipment damage.

[0003] Pest and disease prevention and control: If the cotton stalks stay in the field for a long time, they may become the overwintering hosts of pests such as cotton bollworms and spider mites, increasing the risk of pest and disease occurrence in the following year.

[0004] Resource utilization: Cotton stalks can be used as biomass fuels, papermaking raw materials or organic fertilizer raw materials, but their collection efficiency directly affects the economy of resource utilization.

[0005] Traditional cotton stalk pulling operations mostly rely on manual or simple mechanized operations. This operation method has problems such as low efficiency, high labor intensity, and many residual roots. And most of the existing cotton stalk pulling equipment uses the mechanical rotary blade cutting method. Although it has achieved partial mechanization, it lacks precise control of cotton stalk grasping and conveying, resulting in incomplete pulling out or cotton stalk breakage (only the above-ground part is pulled out, and the roots still remain in the soil). Especially in large-scale planting areas, the pulling cost is high and it is difficult to meet the requirements of farming seasons. Summary of the Invention

[0028] Embodiment 2, refer to Figures 6-7, a cotton stalk pulling machine, wherein the cotton stalk collecting mechanism 3 includes a driving shaft 31, a chain drive assembly 32, a first servo motor 33, a driven shaft 34, a driving gear 35, a roller member 36 and a roller fine adjustment assembly 37. Among them, there are three driving shafts 31, and the driving shafts 31 are rotatably connected to the inner wall of the bottom box 2 through bearings. The chain drive assembly 32 is arranged between two adjacent driving shafts 31. The first servo motor 33 is fixedly connected to the outer wall of one end of a driving shaft 31 through a coupling. There are three driven shafts 34, and the driven shafts 34 are rotatably connected to the inner wall of the bottom box 2 through bearings. The driven shafts 34 correspond to the driving shafts 31 one by one. There are three groups of driving gears 35, and each group of driving gears 35 includes two. The two driving gears 35 in each group are respectively installed on the outer walls of the driving shaft 31 and the driven shaft 34, and the two driving gears 35 mesh 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 walls of the other ends of the driven shaft 34 and the driving shaft 31. The roller fine adjustment assembly 37 is arranged on the outer wall of the roller member 36, and the roller fine adjustment assembly 37 is located below the shovel plate 1.

[0029] In this embodiment, in the cotton stalk collecting mechanism 3, the three groups of driving shafts 31 and the driven shafts 34 are meshed through two driving gears 35, and with the precise drive of the first servo motor 33, the first servo motor 33 can synchronously drive multiple groups of roller members 36 to rotate, and the rotation directions between the two cotton stalk lifting rollers 361 in each group of roller members 36 are opposite, which can continuously pull out the roots of the cotton stalks from the soil, not only reducing the residue rate of the roots, but also avoiding the problem of cotton stalk breakage caused by the cutting method of traditional equipment.

[0030] Refer to Figures 6-7 , the chain drive assembly 32 includes a sprocket 321 and a chain 322. Among them, the sprocket 321 is installed on the outer wall of one end of the driving shaft 31, and the chain 322 meshes with the outer wall of the sprocket 321.

[0031] Refer to Figure 8 , the roller member 36 includes a cotton stalk lifting roller 361, a docking sleeve 362 and a tapered head 363. Among them, the cotton stalk lifting roller 361 is hinged to the outer walls of the other ends 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. The tapered head 363 is fixedly connected to the inner wall of the docking sleeve 362 through a pin.

[0032] The first servo motor 33 drives the three groups of driving shafts 31 to rotate synchronously through a sprocket 321 and a chain 322. The driven shaft 34 rotates in the opposite direction under the meshing of the driving gear 35. The rotation directions between 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 by the rotation of the cotton stalk roller 361 and the conical head 363.

[0033] Embodiment 3, referring 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 horizontal connecting shaft 374 and a horizontal fixing shaft 375. Among them, 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 horizontal connecting shaft 374 is rotatably connected to the outer wall of one side of the sleeve 371, the horizontal fixing shaft 375 is hinged to the outer wall of one end of the horizontal connecting shaft 374. The bottom outer wall of the shovel plate 1 is welded with a plurality of connecting plates 9 distributed in an array, and the horizontal fixing shaft 375 is installed through the outer wall of the connecting plate 9. Nuts are screwed on the outer walls of both ends of the horizontal fixing shaft 375, and the nuts are closely attached to the outer wall of the connecting plate 9.

[0034] Since the sleeve 371 rotates along the docking sleeve 362 and the vertical connecting shaft 372 slides in the arc-shaped groove plate 373, by adjusting the position of the nut, the distance between the horizontal fixing shaft 375 and the sleeve 371 can be adjusted, and then through the linkage cooperation between the horizontal connecting shaft 374 and the horizontal fixing shaft 375, the included angle between the two roller members 36 can be adjusted to ensure balanced pulling force.

[0035] In this embodiment, in the roller fine-tuning assembly 37, the arc-shaped groove plate 373 and the vertical connecting shaft 372 are in sliding fit. Since the roller member 36 is hinged to the driven shaft 34 and the driving shaft 31, by adjusting the positions of the two nuts, the distance between the horizontal fixing shaft 375 and the sleeve 371 can be adjusted, so that the inclination angle of the roller member 36 can be adjusted, which helps the equipment to adapt to environments with different soil hardness or cotton stalk distribution densities, and can reduce the risk of jamming.

[0036] Referring to Figures 1-2, an overall inclination component 6 is provided on one outer wall of the shovel plate 1, and a tractor front baffle 7 for connecting to a tractor is provided on one side of the overall inclination component 6.

[0037] When the hydraulic cylinder 61 expands and contracts to push the relative positions of the bottom box 2 and the tractor front baffle 7, the telescopic rod 62 will slide within the telescopic tube 63 to achieve the angle adjustment of the shovel plate 1, adapting to operations on sloping land or soft soil.

[0038] Refer to Figure 6 , a gearbox 8 distributed at equal distances is fixedly connected to the inner wall of the bottom of the bottom box 2 by screws, and both the driving shaft 31 and the driven shaft 34 are rotatably connected to the inner wall of the gearbox 8 through bearings. The driving gear 35 is arranged inside the gearbox 8. A motor frame 10 is fixedly connected to one outer wall of the bottom box 2 by screws, and the first servo motor 33 is fixedly connected to one outer wall of the motor frame 10 by screws.

[0039] Refer to Figure 4 , a bucket 11 is welded to the other outer wall of the shovel plate 1, and side baffles 12 are welded to both sides of the top outer wall of the shovel plate 1. A plurality of guide openings 13 are formed at equal distances on the other outer wall of the shovel plate 1, and the guide openings 13 are located above the roller members 36. A cotton collecting rod opening 14 is provided between the two cotton discharging rod mechanisms 5 on the top outer wall of the shovel plate 1.

[0040] The bucket 11 can guide the cotton stalks to be pulled out between the two roller members 36. The side baffles 12 can prevent the pulled-out cotton stalks from scattering laterally. The guide openings 13 are used to guide the cotton stalks into the action area of the roller members 36. The cotton collecting rod opening 14 is located between the two cotton discharging rod mechanisms 5, and the cotton stalks are concentrated and output therefrom.

[0041] Working principle: Equipment connection and preparation: Connect the equipment to the tractor through the tractor front baffle 7, adjust the shovel plate 1 to an appropriate inclination angle through the hydraulic cylinder 61, and drive the entire equipment to move through the tractor.

[0042] Cotton stalk pulling stage: The first servo motor 33 is started to drive the driving shaft 31 and the driven shaft 34 to drive the roller members 36 to rotate. As the shovel plate 1 moves, the bucket 11 can approach the cotton stalks and guide the cotton stalks to be pulled out between the two roller members 36. Since the rotation directions between the two roller members 36 in each group are opposite, the cotton stalks are continuously pulled out of the soil by the rotation of the cotton stalk lifting rollers 361 and the cone heads 363.

[0043] Cotton stalk conveying stage: The pulled cotton stalks move up through the guiding port 13 to the top of the shovel plate 1 and close to the cotton stalk discharging mechanism 5. At this time, the cotton stalk traction head 523 on the conveyor belt 521 is responsible for pulling the cotton stalks and conveying them to the cotton stalk collecting port 14 along the belt pulley 522, completing the centralized stacking.
