Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery and relates to a cotton layering topping device, which is particularly suitable for cotton topping operations at different heights. Background Technology

[0002] Topping is an important part of cotton pruning. It can effectively eliminate apical dominance in cotton plants, allowing the bolls on the lateral branches to receive sufficient water and nutrients, reducing ineffective nutrient supply, and promoting earlier and more boll formation.

[0003] Currently, cotton topping methods mainly include chemical topping, manual topping, and mechanical topping. Chemical topping is widely used due to its low cost and simple operation, but its pollution to the soil and environment cannot be ignored. Manual topping can accurately identify and toplate cotton buds with less damage to the cotton, but it is less efficient, labor-intensive for farmers, and prone to missing the optimal topping period, affecting cotton yield. Mechanical topping has obvious advantages and is the main trend for achieving efficient cotton topping. It employs various methods, mainly separating cotton buds by applying forces such as shearing, cutting, pulling, clamping, and beating. However, due to the varying heights of cotton buds, existing technologies still have many problems that need to be solved: single-mechanism topping requires rapid floating of the entire device, resulting in excessive inertial force, which can easily lead to device vibration and delayed topping action, resulting in inaccurate topping. Summary of the Invention

[0004] This invention provides a cotton layered topping device, which arranges several sets of cutters in layers within the height range of the cotton bud, and works in conjunction with a vision recognition system to accurately cut the bud. The device has minimal vibration, good continuous cutting and topping effect, and high work efficiency.

[0005] The present invention provides the following solution: a cotton layering and topping device includes a walking device, a layering and topping device, a conveyor belt drive device, a front height recognition device, and a rear height recognition device. The layering and topping device is installed in the middle of the walking device, the conveyor belt drive device is installed at the rear corner of the layering and topping device, the front height recognition device is installed in front of the layering and topping device, and the lens faces backward to collect image information of the cotton stalk feeding inlet of the layering and topping device. The rear height recognition device is installed opposite the front height recognition device, and the lens faces forward to collect image information of the cotton stalk feeding inlet of the layering and topping device. The front height recognition device and the rear height recognition device are fixedly connected to the walking device.

[0006] The layered topping device includes a left support, a left electrical control box, a cotton stalk feeding conveyor belt, a cutting blade power unit, a cutting blade assembly, a right electrical control box, a right support, a reeling soft tooth, and a pulley assembly. The left and right supports are trapezoidal and symmetrically installed inside the walking device to form a conical feeding inlet. The cutting blade assembly is located behind the conical feeding inlet. The cutting blade power unit is located on both sides of the cutting blade assembly and is installed on the left and right supports respectively. The pulley assembly is installed at the corners of the left and right supports respectively, placed on the outside. The cotton stalk feeding conveyor belt is wrapped around the outside of the pulley assembly. The reeling soft tooth is oriented and fixed to the cotton stalk feeding conveyor belt. The left electrical control box is installed inside the left support, and the right electrical control box is installed inside the right support.

[0007] The left-side electrical control box contains an image processing device, a signal transceiver, a power supply, terminal blocks, a reversing valve assembly, and a pneumatic control valve, while the right-side electrical control box contains terminal blocks, a reversing valve assembly, and a pneumatic control valve.

[0008] The aforementioned cutting blade assembly includes a cutting blade support plate, a cutting blade guide arm, a cutting blade guide block, a disc-shaped cutting blade, a disc-shaped slotted cutting blade, a slotted cutting blade guide block, a slotted cutting blade guide arm, a slotted cutting blade support plate, a slotted cutting blade follower pulley, and a cutting blade follower pulley. The cutting blade support plate is connected to the right-side bracket. The cutting blade guide block is mounted on the cutting blade support plate. One end of the cutting blade guide arm passes through the guide hole of the cutting blade guide block and is connected to the cutting blade power unit. A rotating shaft is set at one end, and the follower pulley of the cutting blade is coaxially connected to the rotating shaft. The disc cutting blade is fixedly connected to the lower end face of the follower pulley. The grooving blade support plate is connected to the left side bracket, and the grooving blade guide block is installed on the grooving blade support plate. One end of the grooving blade guide arm passes through the guide hole of the grooving blade guide block and is connected to the cutting blade power device. The other end is set with a rotating shaft, and the follower pulley of the grooving blade is coaxially connected to the rotating shaft. The disc grooving blade is fixedly connected to the lower end face of the follower pulley.

[0009] The teeth of the groove cutter follower pulley and the blade cutter follower pulley are set at the same height as the corresponding cotton stalk feeding conveyor belt. The disc groove cutter and the disc blade cutter are placed between the two cotton stalk feeding conveyor belts. Multiple sets of disc groove cutters and disc blade cutters are set within the cotton topping height range.

[0010] The working process of the cotton layering and topping device is as follows: the front height recognition device and the rear height recognition device collect images of the cotton buds at the cotton stalk feeding inlet. The image processing device analyzes the image information to obtain the height and horizontal position information of the cotton buds to be cut, and sends it to the signal transceiver. The signal transceiver controls the opening and closing of the reversing valve group at the corresponding height. The corresponding layer's cutting blade power device pushes out or pulls back the disc groove cutter and disc blade cutter. When the cutting blade power device is in the pushing state, the groove cutter follower pulley and the blade cutter follower pulley engage with the cotton stalk feeding conveyor belt, and the disc groove cutter and disc blade cutter rotate accordingly. When the cutting blade power device is in the pulling state, the groove cutter follower pulley and the blade cutter follower pulley separate from the cotton stalk feeding conveyor belt, and the disc groove cutter and disc blade cutter stop rotating accordingly.

[0011] Compared with existing technologies, this invention sets multiple sets of cutting blades within the height distribution range of the cotton bud. Based on the cutting position provided by the vision system, it accurately drives the corresponding layer of cutting blades to complete the topping operation. The device of this invention has good stability, achieves continuous topping effect, and has high work efficiency. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the cotton layered topping device includes a walking device (1), a layered topping device (2), a conveyor belt drive device (3), a front height recognition device (4), and a rear height recognition device (5). The layered topping device (2) is installed in the middle of the walking device (1), the conveyor belt drive device (3) is installed at the rear corner of the layered topping device (2), the front height recognition device (4) is installed in front of the layered topping device (2), and the lens faces backward to collect image information of the cotton stalk feeding inlet of the layered topping device (2). The rear height recognition device (5) is installed opposite the front height recognition device (4), and the lens faces forward to collect image information of the cotton stalk feeding inlet of the layered topping device (2). The front height recognition device (4) and the rear height recognition device (5) are fixedly connected to the walking device (1). The walking device (1) is a gantry structure that can span across the cotton row. Platforms are set on both sides for placing the layered topping device (2). The front height recognition device (4) and the rear height recognition device (5) can collect the position coordinates of the top bud of the cotton topping device.

[0026] like Figure 2As shown, the layered topping device (2) includes a left support (201), a left electrical control box (202), a cotton stalk feeding conveyor belt (203), a cutting blade power unit (204), a cutting blade assembly (205), a right electrical control box (206), a right support (207), a stalk-pulling soft tooth (208), and a pulley group (209). The left support (201) and the right support (207) are trapezoidal and symmetrically installed inside the walking device (1) to form a conical feeding inlet. The conical feeding inlet allows the cotton buds, which are distributed over a wider range, to be arranged sequentially and enter the narrower topping area, reducing the impact force of the mechanical structure on the cotton plant and reducing the cotton boll damage rate. The cutting blade assembly (205) is located behind the conical feeding inlet, and the cutting blade power unit (204) is located on both sides of the cutting blade assembly (205). Installed on the left support (201) and the right support (207), the pulley assembly (209) is installed at the corner of the left support (201) and the right support (207) respectively, placed on the outside. The cotton stalk feeding conveyor belt (203) is wrapped around the outside of the pulley assembly (209). The stalk-pulling soft teeth (208) are fixedly connected to the cotton stalk feeding conveyor belt (203) in an orientation. The cotton stalk feeding conveyor belts (203) on the left and right sides turn in opposite directions. At the feeding inlet, the movement direction of the cotton stalk feeding conveyor belt (203) is always opposite to the direction of travel. The stalk-pulling soft teeth (208) are vertically and evenly distributed on the cotton stalk feeding conveyor belt (203), which can straighten the cotton buds and separate them in different areas. The left electrical control box (202) is installed inside the left support (201), and the right electrical control box (206) is installed inside the right support (207).

[0027] like Figure 7 , Figure 8 As shown, the left electrical control box (202) contains an image processing device (2021), a signal transceiver device (2022), a power supply (2023), a terminal block (2024), a reversing valve assembly (2025), and a pneumatic control valve (2026), while the right electrical control box (206) contains a terminal block (2024), a reversing valve assembly (2025), and a pneumatic control valve (2026).

[0028] like Figure 3 , Figure 4 , Figure 5As shown, the cutting blade assembly (205) includes a blade cutting blade support plate (2051), a blade cutting blade guide arm (2052), a blade cutting blade guide block (2053), a disc blade cutting blade (2054), a disc groove cutting blade (2055), a groove cutting blade guide block (2056), a groove cutting blade guide arm (2057), a groove cutting blade support plate (2058), a groove cutting blade follower pulley (2059), and a blade cutting blade follower pulley (2050). The blade cutting blade support plate (2051) is connected to the right-side bracket (207). The blade cutting blade guide block (2053) is mounted on the blade cutting blade support plate (2051). One end of the blade cutting blade guide arm (2052) passes through the guide hole of the blade cutting blade guide block (2053) and connects with the cutting blade. The power unit (204) is connected to the other end, and a rotating shaft is provided at the other end. The blade follower pulley (2050) is coaxially connected to the rotating shaft. The disc blade cutter (2054) is fixedly connected to the lower end face of the blade follower pulley (2050). The slotting cutter support plate (2058) is connected to the left side bracket (201). The slotting cutter guide block (2056) is installed on the slotting cutter support plate (2058). One end of the slotting cutter guide arm (2057) passes through the guide hole of the slotting cutter guide block (2056) and is connected to the blade power unit (204). The other end is provided with a rotating shaft. The slotting cutter follower pulley (2059) is coaxially connected to the rotating shaft. The disc slotting cutter (2055) is fixedly connected to the lower end face of the slotting cutter follower pulley (2059).

[0029] Along the axial direction of the blade guide arm (2052) and the groove guide arm (2057), a plane is set on the outer cylindrical surface, and the cross-sectional shape of the guide hole of the blade guide block (2053) and the groove guide block (2056) is set to be the same as that of the blade guide arm (2052) and the groove guide arm (2057), so that the blade guide arm (2052) and the groove guide arm (2057) cannot rotate at will, avoiding interference between the disc blade cutter (2054) and the disc groove cutter (2055) and the cotton rod feeding conveyor belt (203), and ensuring accurate alignment of the cutter assembly (205).

[0030] The teeth of the groove cutter follower pulley (2059) and the blade cutter follower pulley (2050) are set at the same height as the corresponding cotton stalk feeding conveyor belt (203). The disc groove cutter (2055) and the disc blade cutter (2054) are placed between the two cotton stalk feeding conveyor belts (203). Multiple sets of disc groove cutters (2055) and disc blade cutters (2054) are set within the cotton topping height range.

[0031] like Figure 6As shown, the material of the disc groove cutter (2055) is hard plastic, and the material of the disc blade cutter (2054) is hard alloy, so as to reduce the damage and wear of the disc blade cutter (2054); the cylindrical surface of the disc groove cutter (2055) is provided with a "V" shaped groove, which can increase the shearing force and guide the cutting.

[0032] The working process of the cotton layering topping device is as follows: the front height recognition device (4) and the rear height recognition device (5) collect images of the cotton buds at the cotton stalk feeding inlet, analyze the image information using the image processing device (2021), obtain the height and horizontal position information of the cotton buds to be cut, and send it to the signal transceiver device (2022). The signal transceiver device (2022) controls the opening and closing of the corresponding height reversing valve group (2025), and the corresponding layering cutting blade power device (204) pushes out or pulls back the disc groove cutter (2055) and the disc blade cutter (2054). When the power unit (204) for cutting is in the extended state, the slotted cutter follower pulley (2059) and the blade follower pulley (2050) engage with the cotton stalk feeding conveyor belt (203), and the disc slotted cutter (2055) and the disc blade cutter (2054) rotate accordingly. When the power unit (204) for cutting is in the retracted state, the slotted cutter follower pulley (2059) and the blade follower pulley (2050) separate from the cotton stalk feeding conveyor belt (203), and the disc slotted cutter (2055) and the disc blade cutter (2054) stop rotating accordingly.

[0033] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively describe all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
