Description

Technical Field

[0001] This invention relates to the field of weed control devices, specifically a weed control device for millet cultivation. Background Technology

[0002] Millet, also known as foxtail millet, is an ancient crop belonging to the genus Setaria of the Poaceae family. It is one of the traditional important food crops in China and East Asia. It has a well-developed root system and is adapted to arid and infertile soils, and is widely planted, especially in the arid and semi-arid regions of the north.

[0003] Weeding is a crucial field management measure in millet cultivation. Weeds compete for nutrients such as water, nitrogen, phosphorus, and potassium in the soil. Especially during the seedling stage, when millet roots are shallow and nutrient absorption is weak, weeds significantly inhibit seedling growth. Weeding devices are needed to control the weeds. Existing weeding devices use a rotating disc to drive multiple hoes to rotate. As the device moves, continuous weeding is achieved. However, the hoes turn up the soil, creating pits. After the hoes turn up the weeds, they fall back into the pits as the disc rotates. The weeds need to be manually removed from the pits, requiring a large amount of manpower to clean up the dug-out weeds, resulting in low work efficiency. Summary of the Invention

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-8 The illustration shows a weed control device for millet cultivation, comprising a device housing 1 and a handle 2 fixedly installed on the outside of the device housing 1. Two symmetrically distributed support arms 3 are fixedly installed on the outside of the device housing 1. A movable wheel 4 is rotatably installed at the end of the support arm 3 away from the device housing 1. When the handle 2 is pushed, the movable wheel 4 on the support arm 3 can be driven to move along the ground. Multiple hoe blades 5 are arranged centrally symmetrically on the inside of the device housing 1. When the device housing 1 is in the moving state, the hoe blades 5 can turn over the weeds. It also includes a harvesting mechanism for collecting and discharging the weeds turned over by the hoe blades 5. The harvesting mechanism is installed on the inside of the device housing 1.

[0035] The harvesting mechanism includes a collection cylinder 6 fixedly installed inside the outer casing 1 of the device. Hoes 5 can feed weeds into the collection cylinder 6. The harvesting mechanism also includes two mounting rings 10 symmetrically rotated and installed on the outside of the collection cylinder 6. Multiple pusher plates 11, arranged centrally symmetrically, are fixedly installed between the two mounting rings 10. The pusher plates 11 have a U-shaped structure, and the number of pusher plates 11 is the same as the number of hoes 5. The pusher plates 11 are fixedly connected to the hoes 5, and the end of the pusher plate 11 away from the hoes 5 contacts the outside of the collection cylinder 6. The top of the collection cylinder 6 has a feed inlet. When the mounting rings 10 rotate, they can... The pusher plate 11 drives the hoe blades 5 to rotate, causing multiple hoe blades 5 to roll and turn over the weeds in the soil, collecting the weeds into the outer casing 1. The pusher plate 11 then pushes the turned-over weeds and soil into the inlet of the collection cylinder 6. The outer casing 1 has a discharge port, allowing the weeds in the collection cylinder 6 to be discharged outwards from the discharge port along the guide plate 8, keeping the weeds away from the soil pits turned over by the hoe blades 5. An installation box 12 is fixedly installed on the outer side of the outer casing 1, and a drive motor 13 is fixedly installed on the outer side of the installation box 12. A toothed part is fixedly installed at the output end of the drive motor 13. The gear drive rod 14 has an annular groove on the outer side of the mounting ring 10 near the drive motor 13. A gear ring 15 that mates with the gear drive rod 14 is fixedly installed on the inner side of the annular groove, causing the drive motor 13 to drive the gear drive rod 14 to rotate. The gear drive rod 14 drives the corresponding mounting ring 10 to rotate along the outer side of the storage cylinder 6 through the gear ring 15. This mounting ring 10, together with another mounting ring 10, drives multiple pusher plates 11 to make a circular motion along the outer side of the storage cylinder 6. The hoe blade 5 can move on the ground to remove weeds with the moving wheels 4. A U-shaped... The baffle 35 guides the weeds and soil lifted by the guide plate 8, facilitating the discharge of soil clods and weeds from the discharge port. A bracket 36 is fixedly installed on the outside of the mounting box 12, and the drive motor 13 is fixedly installed on the inside of the bracket 36. The bracket 36 provides support for the drive motor 13, ensuring the stable operation of the drive motor 13. Two symmetrically distributed protective sleeve shafts 37 are fixedly installed on the inside of the device housing 1. The outer sides of the two protective sleeve shafts 37 respectively contact the outer sides of the two mounting rings 10, improving the smoothness of the rotation of the mounting rings 10 and providing protection for the gear ring 15 and the gear transmission rod 14.

[0036] Example 2: Please refer to Figures 2-6This embodiment further illustrates Example 1. The discharge mechanism shown in the figure includes a guide plate 8 disposed inside the receiving cylinder 6. The guide plate 8 can shake out the soil clods entering the receiving cylinder 6. The discharge mechanism also includes a mounting frame 16 fixedly installed inside the receiving cylinder 6. One end of the guide plate 8 is rotatably installed inside the mounting frame 16. A fixing plate 17 located below the guide plate 8 is fixedly installed inside the outer side of the device housing 1. Two symmetrically distributed sleeves 18 are fixedly installed on the outer side of the fixing plate 17. A sliding rod 19 is slidably installed on the inner side of the sleeve 18. A push roller 20 is rotatably installed between the two sliding rods 19. The outer side of the push roller 20 contacts the side of the guide plate 8 near the fixing plate 17. When roller 20 moves, it can push guide plate 8 to swing. Slide plate 21 is fixedly installed between two slide rods 19. A groove is opened on the outer side of sleeve 18 for slide plate 21 to limit sliding. A tension spring 7 is fixedly installed between the end of slide rod 19 away from push roller 20 and sleeve 18, so that when slide plate 21 moves, slide rod 19 can stretch tension spring 7. The rebound force of tension spring 7 can be used to facilitate slide rod 19 to pull push roller 20 to reset. A driven rod 22 is rotatably installed on the outer side of fixed plate 17. A cam 23 is fixedly installed on the outer side of driven rod 22, so that when cam 23 rotates, it can push slide plate 21 to move, and cooperate with tension spring 7 to realize the reciprocating movement of slide plate 21. Slide plate 21 can move through slide rod 19. 9 drives the push roller 20 to move synchronously, causing the push roller 20 to repeatedly push the guide plate 8 to swing, facilitating the discharge of residual soil on the guide plate 8. A rotating rod 24 extending to the inner side of the device housing 1 is rotatably mounted on the inner side of the mounting box 12. Both the end of the rotating rod 24 and the end of the driven rod 22 are fixedly mounted with matching conical wheels 25, so that when the rotating rod 24 rotates, it can drive the driven rod 22 to rotate through the two conical wheels 25. A synchronous belt 26 is rotatably mounted between the rotating rod 24 and the gear transmission rod 14, so that the gear transmission rod 14 drives the rotating rod 24 to rotate synchronously through the synchronous belt 26. Positioning discs 38 are fixedly mounted on the top and bottom of the cam 23, and the two positioning discs 38 are respectively mounted on the top of the slide plate 21. Contacting the bottom to prevent the cam 23 from falling off the slide plate 21, two symmetrically distributed arc-shaped rods 39 are fixedly installed on the side of the guide plate 8 near the push roller 20. A limit sleeve 40 is slidably installed on the outer side of the arc-shaped rods 39. The limit sleeve 40 is fixedly installed on the outer side of the mounting frame 16. An arc-shaped spring 41 is fixedly installed between the end of the arc-shaped rod 39 away from the guide plate 8 and the limit sleeve 40. When the push roller 20 pushes the guide plate 8 to swing, the guide plate 8 can drive the arc-shaped rod 39 to move along the inner side of the limit sleeve 40 and compress the arc-shaped spring 41. When the push roller 20 resets, the rebound force of the arc-shaped spring 41 can be used to facilitate the quick reset of the guide plate 8 and improve the discharge efficiency.

[0037] Example 3: Please refer to Figure 1 , Figure 7 and Figure 8This embodiment further illustrates other embodiments. The cross-cutting mechanism shown in the figure includes multiple first cutters 9 equidistantly distributed between two moving wheels 4. The first cutters 9 can cut tall weeds. The cross-cutting mechanism also includes a prismatic rod 27 fixedly installed between the two moving wheels 4. The moving wheels 4 can drive the prismatic rod 27 to rotate synchronously. A slide cylinder 28 is slidably installed on the outer side of the prismatic rod 27. Multiple collars 29 equidistantly distributed are rotatably installed on the outer side of the slide cylinder 28. A second cutter 30 is fixedly installed on the outer side of the collars 29. A crossbar 31 is fixedly installed between the two support arms 3. The first cutters 9 are fixedly installed on the outer side of the crossbar 31. The outer side of the second cutters 30 is in contact with the outer side of the crossbar 31. A sleeve 32 is fixedly installed on the side of each support arm 3 near the slide cylinder 28. The slide cylinder 28 is slidably installed between the two sleeves 32. An elastic washer 33 is fixedly installed on one end of the slide cylinder 28. The elastic washer 33 is rotatably installed on the inner side of the adjacent sleeve 32, located on the slide cylinder 28 away from the elastic washer. Multiple centrally symmetrically distributed sliders 34 are installed on the inner side of the sleeve 32 at one end of the ring 33. A spherical groove for limiting the insertion of the sliders 34 is fixedly installed at the end of the slide cylinder 28 away from the elastic washer ring 33. The spherical groove has a one-third spherical structure. The prismatic rod 27 can drive the slide cylinder 28 to rotate, so that the spherical groove on the slide cylinder 28 slides out from the outside of the sliders 34 and compresses the elastic washer ring 33. The sliders 34 can then contact the end of the slide cylinder 28 and align with the sliders 34 again in the spherical groove on the slide cylinder 28. At that time, the elastic force of the elastic pad ring 33 is used to make the spherical groove fit onto the slider 34 again. Thus, as the slider 28 rotates, the slider 28 can swing back and forth along the outside of the prism rod 27. The slider 28 can drive the second cutter 30 to swing synchronously through the collar 29 to cut longer weeds, making it easier for the hoe 5 to dig the roots of the weeds out of the soil. The outer sides of the first cutter 9 and the second cutter 30 are provided with reinforcing ribs to improve the durability of the first cutter 9 and the second cutter 30.

[0038] Working principle: First, the operator starts the drive motor 13 and pushes the handrail 2, causing the moving wheel 4 at the end of the support arm 3 to move along the ground. The moving wheel 4 drives the prismatic rod 27 to rotate, which in turn drives the slide cylinder 28 to rotate synchronously. The spherical groove on the slide cylinder 28 slides out from the outside of the slider 34 and compresses the elastic washer 33. The elasticity of the elastic washer 33 causes the slider 34 to contact the end of the slide cylinder 28. When the spherical groove on the slide cylinder 28 aligns with the slider 34 again, the rebound force of the elastic washer 33 causes the spherical groove to fit onto the slider 34 again. Thus, as the slide cylinder 28 rotates, the spherical groove can repeatedly engage and disengage with the slider 34. 28 can then reciprocate along the outer side of the prismatic rod 27. The slide cylinder 28 drives the collar 29 to move synchronously, causing the second cutter 30 on the outer side of the collar 29 to swing synchronously along the outer side of the crossbar 31. The second cutter 30 can then cooperate with the first cutter 9 to cut the weeds. At the same time, the drive motor 13 drives the gear transmission rod 14 to rotate. The gear transmission rod 14 drives the corresponding mounting ring 10 to rotate through the gear ring 15. This causes the mounting ring 10 to drive the pusher plate 11 to make a circular motion along the outer side of the collection cylinder 6. The pusher plate 11 drives the hoe 5 to move synchronously, causing the hoe 5 to dig the weeds out of the soil with their roots and send them into the inner side of the device housing 1. The weeds and the collection cylinder 6 enter... When the feed inlets are aligned, the pusher plate 11 pushes the weeds and clods into the collection cylinder 6. The weeds and clods are discharged outward from the discharge port of the device housing 1 along the inclined surface of the guide plate 8. At the same time, the gear transmission rod 14 drives the rotating rod 24 to rotate synchronously through the synchronous belt 26. The rotating rod 24 drives the driven rod 22 to rotate synchronously through two cooperating conical wheels 25. The driven rod 22 drives the cam 23 to rotate synchronously. The convex edge of the cam 23 pushes the slide plate 21 to move along the slide groove on the sleeve 18. The slide plate 21 pushes the two slide rods 19 to move synchronously. The two slide rods 19 push the guide plate 8 to swing through the push roller 20 and stretch the tension spring 7. At this time, the guide plate 8 pulls the arc rod. 39 moves along the inner side of the limiting sleeve 40, compressing the arc spring 41. Then, the convex edge of the cam 23 moves away from the slide plate 21. Using the rebound force of the tension spring 7, the slide rod 19 pulls the push roller 20 to reset. Using the rebound force of the arc spring 41, the arc rod 39 pulls the guide plate 8 to reset. Thus, as the cam 23 continues to rotate, the guide plate 8 swings back and forth, shaking the remaining soil clods out from the discharge port of the device housing 1, so that the weeds and soil clods are on the ground on the side of the pit. Finally, the workers clean up the weeds and soil clods on the ground to complete the weeding operation, thereby improving the convenience of weed cleaning and solving the problem of weeds returning to the pit.
