Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an adjustable rice weeding device. Background Technology

[0002] Rice paddies are prone to weed growth. During the growth process, weeds compete with rice seedlings for fertilizer, nutrients, and growing space, which is a major factor affecting rice yield and quality. Weeding devices are needed to ensure rice growth.

[0003] For example, Chinese patent CN112825670B describes a weeding device and its usage method, which includes a weeding motor, two weeding wheels, multiple weeding mechanisms, a weed storage box, a soil loosening motor, a soil loosening shaft, and multiple soil loosening blades. The weeding motor is installed on the rear side of the operating box, and the output end of the weeding motor is provided with a weeding shaft. The two weeding wheels are respectively fitted onto the front and rear sides of the weeding shaft. The multiple weeding mechanisms are evenly installed on the outer circumference of the two weeding wheels. The weed storage box is installed inside the operating box, and the top of the weed storage box is provided with a weed storage opening. A weed discharge pipe is provided between the bottom right side of the weed storage box and the bottom right side of the operating box. The right end of the weed discharge pipe is covered with a weed discharge cover plate. A fixing plate is provided on the left side of the operating box, and the soil loosening motor is installed on the fixing plate. The soil loosening shaft is rotatably connected to the bottom of the fixing plate, and the multiple soil loosening blades are evenly installed on the soil loosening shaft. This device can achieve rapid weeding of farmland and improve weeding efficiency.

[0004] The above structure can only remove weeds between rice rows, but cannot remove weeds between rice plants, resulting in poor cleaning effect. In addition, the weeding structure is lower than the bottom of the roller, which can easily cause damage to the weeding structure when walking on the ground.

[0005] Based on this, the present invention designs an adjustable rice weeding device to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable rice weeding device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An adjustable rice weeding device includes a floating support assembly;

[0009] The floating support assembly for buoyancy support is connected to the rotating weeding assembly for rotating weeding.

[0010] The rotating weeding assembly includes a set of synchronous drive components and multiple sets of rotating components.

The third bevel gear and the first bevel gear are respectively fixedly installed at the upper and lower ends of the straight shaft. The third bevel gear is meshed with a set of second bevel gears, and the first bevel gear is meshed with the fifth bevel gear. The fifth bevel gear and the mounting sleeve are respectively coaxially fixedly installed at both ends of the first connecting shaft. The fifth bevel gear is located inside the mounting cover, and the mounting sleeve is located outside the mounting cover. Multiple sets of rotating rods are fixedly installed on the outer wall of the mounting sleeve at equal intervals along the circumference.

[0017] Furthermore, the chain weeding assembly includes a reciprocating drive assembly and multiple sets of chains.

[0018] Furthermore, the reciprocating drive assembly includes a sliding seat, a crossbar, a first fixed seat, a second connecting shaft, a rolling bearing, a second fixed seat, a convex plate, a sixth bevel gear, and a rotating plate. The first fixed seat is fixedly connected to one side wall of the crossbar and is rotatably connected to the second connecting shaft via a bearing. The sixth bevel gear and the rotating plate are respectively fixedly installed at both ends of the second connecting shaft. The sixth bevel gear meshes with one of the sets of second bevel gears.

The external drive structure moves the connecting assembly, which in turn moves the floating support assembly, which in turn moves the adjustable rolling support assembly. This facilitates the movement of the adjustable rice weeding device, and the rotating and chain weeding assemblies do not contact the ground, thus protecting them. After the adjustable rolling support assembly moves into the paddy field, its bottom is adjusted to be higher than the bottom of the rotating and chain weeding assemblies, allowing them to contact the soil. The rolling support component does not contact the soil in the paddy field. A set of synchronous drive components of the rotating weeding component drives multiple sets of rotating components. These multiple sets of rotating components rotate in the rice row area A and plant area B to remove weeds in these areas. At the same time, a set of synchronous drive components drives a chain weeding component to swing back and forth between the rice plants, removing weeds in plant area C. The boundary between plant areas B and C is located on the outside of the rice stem structure. The rotating weeding component does not contact the rice stem structure, thus achieving the removal of weeds between rice rows and plants. At the same time, it avoids damaging roots and seedlings during weeding, reducing the rate of root and seedling damage. In addition, the weeding process loosens the soil, improves soil permeability, and is beneficial for practical use. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] The present invention will be further described below with reference to embodiments.

[0042] Example 1, please refer to Figures 1-15 An adjustable rice weeding device includes a floating support assembly 1;

[0043] The floating support assembly 1 for buoyancy support is connected to the rotating weeding assembly 5 for rotating weeding;

[0044] The rotating weeding assembly 5 includes a set of synchronous drive assemblies and multiple sets of rotating assemblies. The set of synchronous drive assemblies is fixedly connected to the top of the floating support assembly 1, and the multiple sets of rotating assemblies are fixedly installed at equal intervals inside the top of the floating support assembly 1. The set of synchronous drive assemblies and the multiple sets of rotating assemblies are connected.

[0045] A chain weeding component 6 for clearing weeds between rice plants is fixedly connected to one side of the floating support component 1, and the chain weeding component 6 is connected to a set of synchronous drive components.

[0046] The other side wall of the floating support assembly 1 is fixedly connected to a connecting assembly 4 for connecting to an external driving structure;

[0047] The floating support assembly 1 is also connected to an adjustable rolling support assembly 2 for rotating support of the adjustable rice weeding device. When weeding, the bottom of the adjustable rolling support assembly 2 is set higher than the bottom of the rotating weeding assembly 5 and the chain weeding assembly 6. When not weeding, the bottom of the adjustable rolling support assembly 2 is set lower than the bottom of the rotating weeding assembly 5 and the chain weeding assembly 6.

[0048] Adjust the bottom of the adjustable rolling support assembly 2 to be lower than the bottom of the rotating weeding assembly 5 and the chain weeding assembly 6. Then connect the connecting assembly 4 to the external drive structure. The external drive structure drives the connecting assembly 4 to move, which in turn drives the floating support assembly 1 to move. The floating support assembly 1 then drives the adjustable rolling support assembly 2 to move, facilitating the movement of the adjustable rice weeding device. The rotating weeding assembly 5 and the chain weeding assembly 6 do not contact the ground, thus protecting them. After the adjustable rolling support assembly 2 moves into the paddy field, adjust its bottom to be higher than the bottom of the rotating weeding assembly 5 and the chain weeding assembly 6, allowing them to contact the soil in the paddy field. Furthermore, the adjustable rolling support component 2 does not come into contact with the soil in the paddy field. A set of synchronous drive components of the rotating weeding component 5 drives multiple sets of rotating components. These multiple sets of rotating components rotate in the rice row a area and plant b area to remove weeds in these areas. At the same time, a set of synchronous drive components drives the chain weeding component 6 to swing back and forth between the rice plants. The chain weeding component 6 removes weeds in the plant c area. The boundary between plant b area and plant c area is located on the outside of the rice stem structure. The rotating weeding component 5 does not come into contact with the rice stem structure, thus achieving the removal of weeds between rice rows and plants. At the same time, it avoids damaging roots and seedlings during weeding, reducing the rate of root and seedling damage. In addition, the weeding process loosens the soil, improves soil permeability, and is beneficial for practical use.

[0049] Please see Figures 1-2 The floating support assembly 1 includes two sets of pontoons 11, two sets of straight plates 12 and one set of horizontal plates 13. The two sets of straight plates 12 are fixedly installed at both ends of the bottom of the set of horizontal plates 13. The two sets of pontoons 11 are respectively fixedly installed at the bottom of the two sets of straight plates 12. The rotating weeding assembly 5, the connecting assembly 4 and the chain weeding assembly 6 are all fixedly connected to the set of horizontal plates 13. The adjustable rolling support assembly 2 is set one-to-one with the pontoons 11 and is located outside the pontoons 11.

[0050] The float 11 of the floating support assembly 1 is in contact with the water in the paddy field, and the float 11 supports the adjustable rice weeding device through buoyancy.

[0051] Please see Figures 1-8 , Figures 11-15 The synchronous drive assembly includes a drive device 51, a support side plate 57, a second bevel gear 58, a second horizontal shaft 59, and a fourth bevel gear 511. The drive device 51 is fixedly installed on the top of the horizontal plate 13, and the fourth bevel gear 511 is fixedly installed on the drive end of the drive device 51. The two ends of the second horizontal shaft 59 are rotatably connected to the support side plate 57 through bearings. Multiple sets of second bevel gears 58 are fixedly installed on the second horizontal shaft 59 at equal intervals. One set of second bevel gears 58 meshes with the fourth bevel gear 511, and multiple sets of second bevel gears 58 are connected to multiple sets of rotating components one by one.

[0052] The drive unit 51 is a gasoline engine;

[0053] The rotating assembly includes a straight cylinder 52, a rotating rod 53, a mounting cover 54, a first bevel gear 55, a straight shaft 56, a third bevel gear 510, a fifth bevel gear 512, a first connecting shaft 513, and a mounting sleeve 514. The straight cylinder 52 is fixedly installed at the bottom of the horizontal plate 13, and the mounting cover 54 is fixedly installed at the bottom of the straight cylinder 52. The straight shaft 56 is rotatably connected to the straight cylinder 52 through bearings. The third bevel gear 510 and the first bevel gear 55 are respectively fixedly installed at the upper and lower ends of the straight shaft 56. The third bevel gear 510 is meshed with a set of second bevel gears 58, and the first bevel gear 55 is meshed with the fifth bevel gear 512. The fifth bevel gear 512 and the mounting sleeve 514 are respectively coaxially fixedly installed at both ends of the first connecting shaft 513. The fifth bevel gear 512 is located inside the mounting cover 54, and the mounting sleeve 514 is located outside the mounting cover 54. Multiple sets of rotating rods 53 are fixedly installed on the outer wall of the mounting sleeve 514 at equal intervals along the circumference.

[0054] After the adjustable rolling support assembly 2 is moved to the paddy field, the bottom of the adjustable rolling support assembly 2 is adjusted to be higher than the bottom of the rotating rod 53 of the rotating assembly and the chain weeding assembly 6 of the rotating weeding assembly 5. The rotating rod 53 and the chain weeding assembly 6 of the rotating weeding assembly 5 are in contact with the soil of the paddy field, while the adjustable rolling support assembly 2 is not in contact with the soil of the paddy field. The drive device 51 of a set of synchronous drive components of the rotating weeding assembly 5 drives the fourth bevel gear 511 to rotate. The fourth bevel gear 511 drives one set of second bevel gears 58 to rotate. One set of second bevel gears 58 drives the second horizontal shaft 59 to rotate along the support side plate 57, thereby driving the other second bevel gears 58 to rotate synchronously. All the second bevel gears 58 drive the third bevel gears 510 of multiple sets of rotating components to rotate synchronously. The third bevel gears 510 drive the straight shaft 56 to rotate. The first bevel gear 55 rotates, which in turn drives the fifth bevel gear 512 to rotate. The fifth bevel gear 512 then drives the first connecting shaft 513 to rotate, which in turn drives the rotating rod 53 to rotate. The rotating rod 53 rotates between rice rows (area a) and between rice plants (area b), clearing weeds from these areas. Simultaneously, a set of synchronous drive components drives the chain weeding assembly 6 to swing back and forth between rice plants, clearing weeds from between rice plants (area c). The boundary between areas b and c is located outside the rice stem structure, and the rotating rod 53 does not contact the rice stem structure, thus clearing weeds between rice rows and between rice plants. This process avoids damaging roots and seedlings during weeding, reducing the rate of root and seedling damage. Furthermore, the weeding process loosens the soil, improving soil aeration and facilitating practical use.

[0055] Please see Figure 1 , Figure 5 , Figure 7 and Figure 8 The chain weeding assembly 6 includes a reciprocating drive assembly and multiple sets of chains 61. The reciprocating drive assembly is fixedly connected to the horizontal plate 13. The reciprocating drive assembly is engaged with one of the second fixed seats 68. The multiple sets of chains 61 are hung on the reciprocating drive assembly at equal intervals.

[0056] The reciprocating drive assembly includes a sliding seat 62, a crossbar 63, a first fixed seat 64, a second connecting shaft 65, a rolling bearing 66, a second fixed seat 68, a convex plate 69, a sixth bevel gear 610, and a rotating plate 611. The first fixed seat 64 is fixedly connected to one side wall of the crossbar 13 and is rotatably connected to the second connecting shaft 65 via a bearing. The sixth bevel gear 610 and the rotating plate 611 are respectively fixedly installed at both ends of the second connecting shaft 65. The sixth bevel gear 610 is connected to one of the sets of second bevel gears 5. 8. The end face of the rotating plate 611 away from the sixth bevel gear 610 is fixedly connected to the rolling bearing 66. The convex plate 69 has a straight groove 67 that is in contact with and slidably connected to the rolling bearing 66. Two sets of sliding seats 62 are symmetrically fixedly installed on the side wall of the convex plate 69. Each set of sliding seats 62 is in contact with and slidably connected to two sets of crossbars 63. The two ends of the crossbars 63 are fixedly connected to the second fixed seat 68. The second fixed seat 68 is fixedly connected to one side wall of the crossbar 63. Multiple sets of chains 61 are hung on the convex plate 69 at equal intervals.

[0057] After the adjustable rolling support assembly 2 is moved to the paddy field, the bottom of the adjustable rolling support assembly 2 is adjusted to be higher than the bottom of the rotating rod 53 of the rotating assembly and the chain weeding assembly 6 of the rotating weeding assembly 5. The rotating rod 53 and the chain weeding assembly 6 of the rotating weeding assembly 5 are in contact with the soil of the paddy field, while the adjustable rolling support assembly 2 is not in contact with the soil of the paddy field. The drive device 51 of a set of synchronous drive components of the rotating weeding assembly 5 drives the fourth bevel gear 511 to rotate, and the fourth bevel gear 511 drives one set of second bevel gears 58. The rotation involves one set of second bevel gears 58 driving the second horizontal shaft 59 to rotate along the support side plate 57, thereby driving the other second bevel gears 58 to rotate synchronously. All the second bevel gears 58 drive the third bevel gears 510 of multiple rotating components to rotate synchronously. The third bevel gears 510 drive the straight shaft 56 to rotate, the straight shaft 56 drives the first bevel gear 55 to rotate, the first bevel gear 55 drives the fifth bevel gear 512 to rotate, the fifth bevel gear 512 drives the first connecting shaft 513 to rotate, and the first connecting shaft 513 drives the rotating rod 53 to rotate. The rotating rod 53 rotates between rice rows (area a) and between rice plants (area b), clearing weeds from these areas. Simultaneously, a set of second bevel gears 58 drives the sixth bevel gear 610 of the reciprocating drive assembly of the chain weeding component 6. The sixth bevel gear 610 drives the second connecting shaft 65, which in turn drives the rotating plate 611. The rotating plate 611 then drives the rolling bearing 66, which, in conjunction with the straight groove 67, drives the convex plate 69 to reciprocate. The convex plate 69 then drives the sliding... The movable seat 62 moves back and forth along the crossbar 63, and the convex plate 69 drives the chain 61 to swing back and forth. The chain 61 swings back and forth between the rice plants, and the chain weeding component 6 removes the weeds in the c zone between the plants. The boundary between the b zone and the c zone between the plants is located outside the rice stem structure. The rotating rod 53 does not contact the rice stem structure, thus achieving the removal of weeds between the rice rows and plants. At the same time, it avoids damaging the roots and seedlings during the weeding process, reducing the rate of root and seedling damage. In addition, the weeding process loosens the soil, improves soil permeability, and is beneficial for practical use.

[0058] Please see Figures 1-2 The connecting component 4 includes a set of first connecting plates 41, two sets of fifth movable plates 42 and a set of second connecting plates 43. The set of second connecting plates 43 is fixedly connected to the other side of the horizontal plate 13. The set of first connecting plates 41 is connected to the external driving structure. One end of the two sets of fifth movable plates 42 is rotatably connected to the set of first connecting plates 41, and the other end of the two sets of fifth movable plates 42 is rotatably connected to the set of second connecting plates 43.

[0059] By combining a set of first connecting plates 41, two sets of fifth movable plates 42 and a set of second connecting plates 43 into a parallel structure, the first connecting plate 41 is kept in a vertical state, thereby ensuring that the second connecting plate 43 is in a vertical state, thus ensuring that the chain 61 and the rotating rod 53 are in a vertical state, thereby ensuring the weeding effect of the chain 61 and the rotating rod 53.

[0060] A protective cover 3 is fixedly connected to the top of the horizontal plate 13, and the supporting side plate 57, the second bevel gear 58, the second horizontal shaft 59, the third bevel gear 510, the fourth bevel gear 511 and the sixth bevel gear 610 are all located inside the protective cover 3.

[0061] The protective cover 3 provides waterproof protection for the support side plate 57, the second bevel gear 58, the second horizontal shaft 59, the third bevel gear 510, the fourth bevel gear 511, and the sixth bevel gear 610, thereby extending their service life.

[0062] Please see Figure 1 , Figures 9-13 The adjustable rolling support assembly 2 includes a locking assembly, an adjusting assembly, and two rolling assemblies. The adjusting assembly is rotatably connected to the two rolling assemblies, the adjusting assembly is rotatably connected to the locking assembly, and the locking assembly is fixedly connected to the horizontal plate 13. The two rolling assemblies are symmetrically rotatably installed at both ends of the outer side wall of the horizontal plate 13.

[0063] The adjustment assembly includes a set of second movable plates 24 and two sets of third movable plates 25. The two ends of the set of second movable plates 24 are rotatably connected to one end of the two sets of third movable plates 25, respectively. The other ends of the two sets of third movable plates 25 are rotatably connected to two sets of rolling assemblies. The middle of the set of second movable plates 24 is rotatably connected to a set of locking assemblies.

[0064] The rolling assembly includes a set of first horizontal shafts 21, a set of first movable plates 22, and a set of rollers 23. The middle end of the set of first movable plates 22 is rotatably connected to the set of first horizontal shafts 21. The set of first horizontal shafts 21 is fixedly installed on the outer wall of the horizontal plate 13. The upper end of the set of first movable plates 22 is rotatably connected to the other end of the set of third movable plates 25. The lower end of the set of first movable plates 22 is rotatably connected to the rollers 23.

[0065] The locking assembly includes a set of square insert plates 26, a set of plug-in sleeves 27, a set of fourth movable plates 28, a set of springs 29, and a set of pull plates 210. The middle of a set of second movable plates 24 is rotatably connected to one end of a set of fourth movable plates 28. The other end of a set of fourth movable plates 28 is fixedly connected to one end of a spring 29. The other end of a spring 29 is fixedly connected to a set of pull plates 210. A set of pull plates 210 is fixedly connected to one end of a set of square insert plates 26. The other end of a set of square insert plates 26 passes through a spring 29 and a fourth movable plate 28 and is plugged into a plug-in sleeve 27. A set of plug-in sleeves 27 is fixedly connected to the side wall of a horizontal plate 13.

[0066] like Figure 11 and Figure 13 Pulling the locking plate 210 of the adjustable rolling support assembly 2 causes the square insert plate 26 to separate from the insertion sleeve 27, and the spring 29 is in a stretched state. Then, pushing the second movable plate 24 of the adjusting assembly upward, the second movable plate 24 drives the third movable plate 25 upward, the third movable plate 25 drives the first movable plate 22 of the rolling assembly to rotate along the first horizontal axis 21, the first movable plate 22 drives the roller 23 downward. After the bottom of the roller 23 is adjusted to be lower than the bottom of the rotating weeding assembly 5 and the chain weeding assembly 6, the driving of the second movable plate 24 is stopped. The fourth movable plate 28 is moved to the position above the insertion sleeve 27. Then the fourth movable plate 28 is rotated, and the fourth movable plate 28 drives the square insertion plate 26 to be aligned with the insertion sleeve 27. The pull plate 210 is released, and the spring 29 drives the pull plate 210 to move. The pull plate 210 drives the square insertion plate 26 to move. The square insertion plate 26 moves into the insertion sleeve 27. The square insertion plate 26 and the insertion sleeve 27 cooperate to lock the fourth movable plate 28, thereby locking the second movable plate 24. Then the first horizontal axis 21 is locked through the third movable plate 25 and the first movable plate 22, so that the roller 23 can rotate and support.

[0067] Then connect the connecting component 4 to the external drive structure. The external drive structure drives the connecting component 4 to move. The connecting component 4 drives the floating support component 1 to move. The floating support component 1 drives the roller 23. The roller 23 rotates and supports, which facilitates the movement of the adjustable rice weeding device. The rotating weeding component 5 and the chain weeding component 6 do not contact the ground, thus protecting the rotating weeding component 5 and the chain weeding component 6.

[0068] like Figure 10 and Figure 12After the roller 23 moves to the paddy field, the locking plate 210 of the adjustable rolling support assembly 2 is pulled, causing the square insert plate 26 to separate from the insertion sleeve 27, and the spring 29 is in a stretched state. Then, the second movable plate 24 of the adjusting assembly is pushed to move downward. The second movable plate 24 drives the third movable plate 25 to move downward. The third movable plate 25 drives the first movable plate 22 of the rolling assembly to rotate along the first horizontal axis 21. The first movable plate 22 drives the roller 23 to move upward. After the bottom of the roller 23 is adjusted to be higher than the bottom of the rotating weeding assembly 5 and the chain weeding assembly 6, the second movable plate 24 is stopped. The connection between the second movable plate 24 and the fourth movable plate 28 moves to below the insertion sleeve 27, and then rotates... The fourth movable plate 28 is moved, causing the square insert plate 26 to align with the insertion sleeve 27. The pull plate 210 is released, and the spring 29 moves the pull plate 210, which in turn moves the square insert plate 26. The square insert plate 26 moves into the insertion sleeve 27, where it and the insertion sleeve 27 lock the fourth movable plate 28, thereby locking the second movable plate 24. The third movable plate 25 and the first movable plate 22 then lock the first horizontal axis 21. The weeding assembly 5 and the chain weeding assembly 6 rotate and come into contact with the soil in the paddy field, while the roller 23 does not come into contact with the soil. This reduces the movement resistance of the adjustable rice weeding device in the paddy field, and the roller 23 also provides a certain amount of buoyancy.
