Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a weeding device for cotton fields. Background Technology
[0002] Currently, in cotton cultivation, weeds compete with cotton plants for nutrients, water, sunlight, and growing space, severely impacting cotton growth, development, and yield. Common weeding methods include manual and mechanical weeding. Manual weeding is inefficient and costly, making it unsuitable for large-scale cultivation. While mechanical weeding is more efficient, failure to promptly collect and destroy weeds after removal can lead to numerous adverse effects.
[0003] Weeds remaining in cotton fields will continue to grow and reproduce. Their roots will extend into the soil, competing with cotton roots for nutrients and water. This leads to insufficient nutrient supply for cotton growth, affecting normal plant development, causing stunted growth, yellowing leaves, and reduced yield and quality. Furthermore, weeds serve as hosts for various pests and diseases. The weeds remaining in cotton fields provide habitats and breeding grounds for pests and easily breed pathogens. Pests and pathogens can then spread to cotton plants via weeds, causing pest and disease outbreaks and increasing the difficulty and cost of pest and disease control. Utility Model Content

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Please combine Figures 1-5 This embodiment of a weeding device for cotton fields includes a movable base 1. One side of the movable base 1 is provided with a soil turning component that can turn up the soil. One side of the soil turning component is provided with a conveying component that can transport the turned-up soil. One side of the conveying component is provided with a crushing component that can crush the transported soil.
[0028] The crushing assembly includes a crushing box 401 fixedly installed on the top of the mobile base 1. Multiple first rotating shafts 402 are rotatably installed inside the crushing box 401. Multiple saw blades 403 are fixedly sleeved on each first rotating shaft 402. The saw blades 403 on every two adjacent first rotating shafts 402 are staggered. A first discharge port is opened at the bottom of the mobile base 1. A baffle 15 is provided on one side of the mobile base 1. One side of the baffle 15 passes through the mobile base 1 and extends into the interior of the first discharge port. A second discharge port is opened at the bottom of the crushing box 401. The first discharge port and the second discharge port are connected.
[0029] The soil turning component turns up the soil containing weeds, loosening and separating the weeds from the soil for easy collection later. The conveying component transports the turned-up soil and weeds to the crushing component, realizing automatic transportation of weeds and improving work efficiency. The saw blades 403 of the crushing component are staggered, which can fully crush the soil and weeds when rotating. The crushed soil and weeds are discharged through the connected first discharge port and second discharge port for easy processing.
[0030] Each first rotating shaft 402 has a first drive gear 5 fixedly mounted on the same end of the first rotating shaft 402 located outside the crushing box 401, and each two adjacent first drive gears 5 are meshed together.
[0031] When one of the first drive gears 5 rotates, it will drive the adjacent first drive gear 5 to rotate, thereby causing multiple first rotating shafts 402 to rotate synchronously, ensuring that the saw blade 403 works in coordination to stably and efficiently crush grass and soil.
[0032] The conveying assembly includes a second rotating shaft 301 mounted on the top of the movable base 1, and a third rotating shaft 302 mounted on one side of the movable base 1. A conveyor belt 303 is fitted onto the second and third rotating shafts 301 and 302. Multiple grass hooks 304 arranged in an array are fixedly mounted on the conveyor belt 303. The second and third rotating shafts 301 and 302 drive the conveyor belt 303 to rotate, and the grass hooks 304 move with the conveyor belt 303, hooking up turned-up weeds and conveying them to the top of the shredding box 401, thus achieving automatic weed conveying. A first connecting plate 6 is fixedly installed on both sides, and a second connecting plate 7 is fixedly installed on one side of each of the two first connecting plates 6. The bottom ends of the two second connecting plates 7 are rotatably engaged with the third rotating shaft 302. The two ends of the second rotating shaft 301 are rotatably fitted with third connecting plates 8. One side of each of the two third connecting plates 8 is fixedly installed with the movable base 1. The first connecting plates 6, the second connecting plates 7 and the third connecting plates 8 provide stable support for the second rotating shaft 301 and the third rotating shaft 302, ensuring the smooth operation of the conveyor belt 303 and improving the stability of the conveying component.
[0033] The soil-turning assembly includes an installation strip 201 fixedly installed at one end of two first connecting plates 6. Multiple fourth connecting plates 202 arranged in an array are fixedly installed at the bottom of the installation strip 201. A fifth connecting plate 203 is provided on one side of each fourth connecting plate 202. A soil-breaking plate 204 is fixedly installed at the bottom of each fifth connecting plate 203. An "L"-shaped first fixing plate 9 is provided on one side of each fourth connecting plate 202. One side of each first fixing plate 9 penetrates adjacent fourth connecting plates 202 and fifth connecting plates 203. An "L"-shaped second fixing plate 10 is provided on one side of each first fixing plate 9. One side of each second fixing plate 10 penetrates adjacent first fixing plates 9.
[0034] The installation strip 201, the fourth connecting plate 202, the fifth connecting plate 203 and the soil-breaking plate 204 cooperate with each other. The soil-breaking plate 204 is inserted into the soil to turn it up. The first fixing plate 9 and the second fixing plate 10 play the role of installation and disassembly.
[0035] A second drive gear 11 is fixedly sleeved on one end of the second rotating shaft 301. A stepper motor 12 is provided on one side of the crushing box 401. The output shaft of the stepper motor 12 is fixedly installed on one end of the adjacent first rotating shaft 402. A third drive gear 13 is fixedly sleeved on the output shaft of the stepper motor 12. A synchronous belt 14 is sleeved on the second drive gear 11 and the third drive gear 13.
[0036] The implementation principle of a weeding device for cotton fields in this application embodiment is as follows: When the device starts working, the stepper motor 12 starts, and its output shaft drives the first rotating shaft 402 connected to it to rotate. The first drive gear 5 at the end of the first rotating shaft 402 rotates accordingly. Since the adjacent first drive gears 5 mesh with each other, multiple first rotating shafts 402 rotate synchronously, driving the saw blade 403 to rotate at high speed, preparing for crushing grass and soil.
[0037] At the same time, the third drive gear 13 on the output shaft of the stepper motor 12 rotates, which drives the second drive gear 11 to rotate through the synchronous belt 14. The second drive gear 11 is fixed on the second rotating shaft 301, thereby causing the second rotating shaft 301 to rotate. The second rotating shaft 301 and the third rotating shaft 302 drive the conveyor belt 303 to rotate, and the grass hooks 304 on the conveyor belt 303 move with the conveyor belt 303.
[0038] After the stepper motor 12 starts, its output shaft drives the first rotating shaft 402 and the third drive gear 13 to rotate. The third drive gear 13 drives the second drive gear 11 to rotate through the synchronous belt 14, which in turn causes the second rotating shaft 301 to rotate. This enables the soil turning component, conveying component and crushing component to work together. Multiple components are driven by one power source, reducing energy consumption and improving the overall operating efficiency of the equipment.
[0039] While the conveyor belt 303 is running, the soil-breaking plate 204 of the soil-turning assembly is inserted into the soil as the equipment moves. The mounting strip 201, the fourth connecting plate 202, and the fifth connecting plate 203 provide support for the soil-breaking plate 204. The first fixing plate 9 and the second fixing plate 10 ensure the stability of the soil-turning structure. The soil-breaking plate 204 turns up the soil containing weeds, loosening and separating the weeds from the soil. When soil turning is no longer needed, the second fixing plate 10 and the first fixing plate 9 can be removed, and the soil-breaking plate 204 can be removed to avoid affecting the movement of the equipment.
[0040] The grass hooks 304 on the operating conveyor belt 303 hook the turned-up weeds. As the conveyor belt 303 moves, the weeds are transported to the top of the crushing box 401. After the weeds fall into the crushing box 401, the staggered saw blades 403 thoroughly crush the weeds.
[0041] The crushed grass and soil are discharged through the second discharge port at the bottom of the crushing box 401 and the first discharge port at the bottom of the movable base 1, so that the crushed grass and soil are evenly covered on the surface of the cotton field soil. The baffle 15 on one side of the movable base 1 can be selected to discharge the grass and soil. The crushed weeds and straw covering the soil surface reduce the sunlight on the soil surface and inhibit the growth of weeds. At the same time, as time goes by, these crushed weeds and straws will gradually decompose, increase the organic matter content in the soil, improve the soil structure, improve the soil fertility, and create a better environment for cotton growth.
[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
