Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton planting technology, and in particular to a multi-directional adjustable cotton topping device. Background Technology
[0002] Topping is a crucial field management measure in cotton cultivation. Its core function is to regulate the growth pattern of cotton plants, optimize nutrient distribution, and ultimately increase yield and income. Cotton has an indeterminate growth habit. If topping is not done in time, the plant will continue to grow upward, resulting in excessive apical dominance. Nutrients will be excessively concentrated in the main stem and top branches and leaves, leading to poor development of fruiting branches in the middle and lower parts, increased bud and boll shedding rate, and prolonged growth cycle. It also makes the plant more susceptible to late frost damage. Mechanically removing the top bud of the cotton plant (topping) can break the apical dominance, promote the transfer of nutrients to lateral branches and reproductive organs, and promote more fruiting branches and more bolls.
[0003] Existing cotton topping devices typically use high-speed rotating blades or swivel blades to cut off the top of cotton plants using centrifugal force. However, the installation height of multiple sets of blades is fixed, making it impossible to adjust the height of different blades individually according to needs. Cotton plants have individual differences in growth, and blades with fixed heights cannot adapt to these differences, easily creating cutting blind spots and reducing the overall coverage rate. Furthermore, the fixed spacing between blades makes it difficult to cover all targets when there are differences in the row spacing of cotton planting. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Example 1:
[0026] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a multi-directional adjustable cotton topping device, including a support base 1, a support frame 2 fixed to the top of the support base 1, a fixed frame 3 slidably connected to the inner wall of the support frame 2, a fixed plate 4 fixed to one side of the fixed frame 3, a housing 5 fixed to one side of the fixed plate 4, and a driving component 6 for adjusting the topping height provided on the top of the support frame 2.
[0027] The drive component 6 can drive the fixed frame 3 to rise and fall, thereby achieving overall height adjustment. The fixed frame 3 connects the support frame 2 and the fixed plate 4, transmitting the power for height adjustment, thus adapting to the height of cotton plants at different growth stages.
[0028] The housing 5 has three sets of horizontally arranged mounting brackets 7 inside, with the middle mounting bracket 7 fixed to the inner wall of the housing 5. A connecting bracket 8 is provided on one side of the mounting bracket 7, a connecting plate 9 is fixed on one side of the connecting bracket 8, a first motor 10 is fixed on one side of the connecting bracket 8, and a cutter head 11 is fixed to the output end of the first motor 10. Each set of mounting brackets 7 has an electric push rod 12 fixed to the inner wall for individually adjusting the height of the connecting bracket 8, and the piston rod of the electric push rod 12 is fixed to one side of the connecting bracket 8. The mounting brackets 7 on both sides have a mounting seat 13 fixed to one side, and an adjustment component 14 for adjusting the spacing of the mounting brackets 7 is provided on one side of the mounting seat 13.
[0029] The first motor 10 drives the cutter head 11 to rotate, directly cutting the top of the cotton plant to complete the topping. The electric push rod 12 enables independent adjustment of the topping height of a single row. The piston rod extends and retracts to drive the connecting frame 8 to move vertically. Each set of mounting frames 7 is equipped with an independent electric push rod 12 to adapt to the problem of uneven cotton plant growth. The adjustment component 14 drives the two mounting frames 7 to move horizontally, achieving the effect of adjusting the distance between the mounting frames 7. This allows the topping device to quickly switch to different row spacings, avoiding missed or repeated operations due to mismatched row spacing, and improving the versatility of the device.
[0030] The adjustment assembly 14 includes a second motor 141 fixed to the inner wall of the housing 5. A gear 142 is fixed to the output end of the second motor 141. Two sets of parallel toothed plates 143 are meshed on the outer side of the gear 142, and one side of the toothed plate 143 is fixed to one side of the mounting base 13.
[0031] The second motor 141 drives the gear 142 to rotate. The rotation of the gear 142 drives the two sets of toothed plates 143 to move horizontally, thereby driving the mounting base 13 and the mounting brackets 7 on both sides to move, thus adjusting the spacing of the mounting brackets 7 according to the cotton row spacing.
[0032] Example 2:
[0033] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0034] Specifically, the drive component 6 includes a protective cover 61 fixed to the top of the support frame 2. A vertically arranged third motor 62 is fixed to the bottom of the inner cavity of the protective cover 61. A threaded rod 63 is fixed to the output end of the third motor 62, and the outer side of the threaded rod 63 is threadedly connected to the inner wall of the fixed frame 3.
[0035] The protective cover 61 protects the third motor 62 from dust and damage. The third motor 62 can drive the threaded rod 63 to rotate. When rotating, the fixed frame 3 is raised and lowered through the screw principle, thereby driving the fixed plate 4 and the shell 5 to rise and fall, adapting to the height of cotton plants at different growth stages.
[0036] Specifically, a guide rail 15 is fixed on one side of the support frame 2, and a slider 16 is fixed on one side of the fixing plate 4, with the inner wall of the slider 16 slidably connected to the inner wall of the guide rail 15.
[0037] The movement of housing 5 causes slider 16 to slide on the inner wall of guide rail 15, so that fixed plate 4 and housing 5 move vertically up and down, improving the stability of housing 5 moving up and down.
[0038] Specifically, a guide rod 17 is fixed to the top of the support base 1, and the outer side of the guide rod 17 is slidably connected to the inner wall of the fixing frame 3.
[0039] The movement of the fixed plate 4 will cause the fixed frame 3 to slide on the outside of the guide rod 17, which works in conjunction with the slider 16 and the guide rail 15 to form a double guide structure and improve the stability of the device.
[0040] Example 3:
[0041] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0042] Specifically, a limiting frame 18 is fixed on one side of the mounting frame 7, and a limiting block 19 is fixed on one side of the connecting frame 8, with the inner wall of the limiting block 19 slidably connected to the inner wall of the limiting frame 18.
[0043] The electric push rod 12 pushes the connecting frame 8 to move, causing the limiting block 19 to slide on the inner wall of the limiting frame 18. The sliding cooperation ensures that the connecting frame 8 moves within a limited range.
[0044] Specifically, two sets of parallel guide frames 20 are fixed to the inner wall of the housing 5. A guide plate 21 is slidably connected to the inner wall of the guide frame 20, and one side of the guide plate 21 is fixedly connected to one side of the toothed plate 143.
[0045] The movement of the toothed plate 143 will cause the guide plate 21 to slide inside the guide frame 20, so that the toothed plate 143 moves in a straight line, thereby causing the mounting frame 7 to move horizontally, improving the stability of the mounting frame 7 when it moves.
[0046] Specifically, a fixing seat 22 is fixed on one side of the support base 1, and a mounting plate 23 is fixed on one side of the fixing seat 22. The mounting plate 23 has multiple sets of mounting holes in its inner cavity.
[0047] The support base 1 is connected to the tractor suspension via the fixed base 22 and the mounting plate 23. The multiple sets of mounting holes on the mounting plate 23 can be adapted to different models of tractors, ensuring the stability of the device during operation.
[0048] In use, the third motor 62 drives the threaded rod 63 to rotate, and the screw principle drives the fixed frame 3 to rise and fall vertically along the guide rod 17. The fixed frame 3 is rigidly connected to the housing 5 through the fixed plate 4, and the overall height can be adjusted synchronously to adapt to the topping height requirements of cotton plants at different growth stages. The first motor 10 drives the cutter head 11 to rotate, realizing the cutting of the top of a single row of cotton plants. When the electric push rod 12 extends and retracts, it drives the connecting frame 8 to slide vertically along the limiting frame 18. The sliding cooperation between the limiting block 19 and the limiting frame 18 limits the range of motion and prevents deviation. Multiple sets of electric push rods 12 can move independently, and the height of the cutter head 11 can be adjusted according to the height of a single row of cotton. The second motor 141 drives the gear 142 to rotate, so that the two sets of toothed plates 143 move linearly. The toothed plates 143 drive the mounting base 13 and the mounting frames 7 on both sides to move horizontally, realizing row spacing adjustment. This allows the topping device to quickly switch to different row spacings, avoiding missed or repeated operations due to row spacing mismatch, and improving the versatility of the device.
[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
