Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an integrated machine for sowing and mulching chives. Background Technology

[0002] With the gradual improvement of mechanization in China, various industries have achieved a high level of mechanization. However, agricultural mechanization still lags behind. For example, in the process of sowing chives, the mechanization level of soil mulching and sowing is low, and most of it still relies on manual operation. Farmers manually place a fixed amount of chive seeds into pre-dug holes and cover them with a suitable amount of soil. Then, they manually cover the soil surface with plastic film, covering both sides with soil. This method of sowing chives, especially in large planting areas requiring precision, often requires a large number of people. For example, one person might hold the string, another dig holes at equal intervals, and yet another place a fixed amount of seeds and cover them with soil, with three people working together to cover the soil. This manual sowing method not only demands high skill from farmers—ensuring that each hole is spaced evenly and that the soil covering is as uniform as possible—but also consumes a lot of physical strength. Furthermore, it suffers from low work efficiency and high labor costs. Summary of the Invention

[0056] Specifically, as another optional implementation of each seeding mechanism 200: each seeding mechanism 200 includes a splash guard 201, a housing 202, a fan blade 203, a uniform distribution plate 204, a plastic brush 205, a seeding tray 206, a seed outlet partition 207, a seed outlet tube 208, a first large sprocket, a first small sprocket, a first chain, a first motor 212, a first connecting shaft 213, and a first support rod 214; the splash guard 201 is located on top of the housing 202, the housing 202 is located on top of the seed outlet partition 207, the fan blade 203 is located inside the housing 202 and installed on top of the seeding tray 206 with an interference fit; the uniform distribution plate 204 and the plastic brush 205 are both located between the housing 202 and the seeding tray 206 to cooperate in achieving equal seeding operations; the seeding tray 206... 6 is located at the bottom of the outer shell 202.

The first large sprocket then drives the sorting disc 206 to rotate, which in turn drives the fan blade 203 to rotate.

[0057] Specifically, in the optional embodiment of the seeding mechanism 200 described above, the outer shell 202 includes a cylindrical tube 2021 and a circular partition 2022 disposed inside the cylindrical tube 2021. A splash guard 201 covers the top of the cylindrical tube 2021, and the bottom of the cylindrical tube 2021 is supported on the top of the seed outlet partition 207. The circular partition 2022 divides the inner cavity of the cylindrical tube 2021 into upper and lower compartments. A fan blade 203 is disposed in the upper compartment of the circular partition 2022, and a uniform sheet 204 and a plastic brush 204 are disposed in the lower compartment of the circular partition 2022. 05 and the seeding tray 206, the circular partition 2022 also has a first through hole 2023 in the middle for the top of the seeding tray 206 to pass through, and a seed inlet 2024 at one end of the circular partition 2022 for the intake of leek seeds. A pair of limiting strips 2025 are provided on the lower outer peripheral wall of the circular partition 2022 and the inner wall of the circular cylinder 2021. A limiting chamber is formed between the pair of limiting strips 2025 on the lower outer peripheral wall of the circular partition 2022 and the pair of limiting strips 2025 on the inner wall of the circular cylinder 2021 for the installation of plastic brush 205.

[0058] Specifically, in the optional embodiment of the seeding mechanism 200 described above, the seeding tray 206 includes a central cylinder 2061 and a disc 2062 sleeved outside the central cylinder 2061. The upper end of the central cylinder 2061 passes through the first through hole 2023 in the middle of the circular partition 2022 and extends into the compartment in the upper part of the circular partition 2022 and is connected to the fan blade 203. The lower end of the central cylinder 2061 passes through the seed outlet partition 207 and extends to the first large pulley 209 (or the first... Inside a large sprocket, a disc 2062 has several seed-draining holes 2063, and the diameter of these holes 2063 is the same and adapted to the size of the chive seeds, so as to achieve equal seeding. This is because the seeding disc 206 has a certain thickness. When the diameter of each seed-draining hole 2063 is the same and adapted to the size of the chive seeds, each seed-draining hole 2063 can hold the same number of chive seeds, thus achieving equal seeding.

[0059] Specifically, in the above-mentioned 200 optional embodiments of the sorting mechanism, see [reference]. Figure 13 The seed outlet partition plate 207 has a second through hole 2071 in the middle for the central cylinder 2061 to pass through. One end of the seed outlet partition plate 207 has a seed outlet 2072, which is directly opposite to and connected to the seed outlet tube 208. The seed outlet 2072 is used to allow the chive seeds to fall into the seed outlet tube 208, and then fall into the sowing mechanism 300 from the seed outlet tube 208.

[0060] When equal-quantity sowing is required, first open the top splash guard 201, then place an appropriate amount of chive seeds into the outer shell 202. Next, the first motor 212 drives the first synchronous belt 211 (or the first chain) to rotate the fan blades 203, causing all the chive seeds in the outer shell 202 to enter the sowing mechanism 200 evenly from the seed inlet 2024 and fall onto the sowing tray 206. The seeds then rotate with the sowing tray 206. When the chive seeds reach the plastic brush 205, the number of seeds transported forward is reduced by the plastic brush 205. As the rotation continues to the even-distribution plate 204, some chive seeds will be blocked by the even-distribution plate 204, while other chive seeds will remain on the even-distribution plate 204. The chive seeds remaining in the seed holes 2063 of the seeding tray 206 below the uniform plate 204 will be divided according to the size of the seed holes 2063 (because the seeding tray 206 has a certain thickness, each seed hole 2063 can only hold a certain amount of seeds). When the chive seeds remaining in the seed holes 2063 of the seeding tray 206 move to the seed outlet 2072 on the seed outlet partition plate 207, they will fall from the seed outlet 2072 into the sowing mechanism 300, and then fall into the soil from the sowing mechanism 300. At this point, the entire seeding mechanism 200 can complete one equal-quantity seeding process. To continue the next equal-quantity seeding operation, the above operation can be repeated.

[0061] Specifically, see Figures 19 to 24 As an optional embodiment of the sowing mechanism 300: the sowing mechanism 300 includes a second motor 301, a second connecting shaft 302, a grooved wheel 303, and an inverted U-shaped connecting rod 305. The second motor 301 is fixedly mounted on the frame 100. One end of the second connecting shaft 302 is connected to the second motor 301, and the other end is connected to the grooved wheel 303. The upper middle part of the inverted U-shaped connecting rod 305 is slidably connected to the cam groove 303a provided on the front side of the grooved wheel 303 via a connecting rod 304 (i.e., the connecting rod 304 is movably inserted into the cam groove 303a). Two seed inlet tubes 306 are provided on the left and right sides of the inverted U-shaped connecting rod 305. Two opening and closing devices 307 are provided, and each seed inlet tube 306 is slidably connected to an inverted U-shaped connecting rod 305. Each opening and closing device 307 is hooked to the inverted U-shaped connecting rod 305. A seed outlet tube 208 is inserted inside each seed inlet tube 306 and is connected to it. An opening and closing device 307 is fitted onto the bottom of each seed inlet tube 306. The inverted U-shaped connecting rod 304 can move up and down under the action of the grooved wheel 303, thus enabling the two opening and closing devices 307 to open and close in a regular manner; that is, when the large end of the cam block in the cam groove 303a rotates to the lower position (e.g....). Figure 19As shown), the inverted U-shaped connecting rod 304 will move upward a certain distance under the action of the grooved wheel 303. When the inverted U-shaped connecting rod 304 moves upward a certain distance, it will drive the opening and closing device 307 to open. When the lower end of the cam block in the cam groove 303a rotates to the bottom, the inverted U-shaped connecting rod 304 will move downward a certain distance under the action of the grooved wheel 303. When the inverted U-shaped connecting rod 304 moves downward a certain distance, it will drive the opening and closing device 307 to close.

[0062] Specifically, in the alternative embodiment of the seeding mechanism 300 described above, the groove wheel 303 and the connecting rod 304 are lubricated with tetrafluoroethylene (PTFE) grease.

[0063] Specifically, in the optional embodiments of the seeding mechanism 300 described above, please refer to... Figure 21 Each opening and closing structure 307 includes a sowing ditch 3071, a movable ditch 3072, and a top plate 3073. The sowing ditch 3071 is fixed to the bottom of the seed inlet pipe 306 on the same side. One end of the movable ditch 3072 is hooked to the inverted U-shaped connecting rod 305, and the other end is connected to the sowing ditch 3071 in an openable and closable manner. Both ends of the top plate 3073 are hinged to the sowing ditch 3071 and the movable ditch 3072 respectively, used to control the opening degree between the movable ditch 3072 and the sowing ditch 3071 to prevent the movable ditch 3072 from opening too large. The movable ditch 3072 can achieve an opening and closing connection with the sowing ditch 3071 by moving the inverted U-shaped connecting rod 305 up and down. The top plate 3073 can block the movable ditch 3072, preventing the movable ditch 3072 from opening too large. When the inverted U-shaped connecting rod 305 moves upward, it causes the upper end of the movable groove 3072 to flip upward, while the lower end of the movable groove 3072 flips downward, opening the movable groove 3072 and the lower end of the sowing groove 3071, thus opening the opening of the opening and closing structure 307. When the inverted U-shaped connecting rod 305 moves downward, it causes the upper end of the movable groove 3072 to flip downward, while the lower end of the movable groove 3072 flips upward, closing the movable groove 3072 and the lower end of the sowing groove 3071, thus closing the opening of the opening and closing structure 307.

[0064] When equidistant sowing is required, the second motor 301 first drives the grooved wheel 303 to rotate. Then, the grooved wheel 303 drives the inverted U-shaped connecting rod 305 to move up and down reciprocally. This causes the inverted U-shaped connecting rod 305 to drive the two opening and closing devices 307 to open and close in a regular manner (that is, when the grooved wheel 303 drives the inverted U-shaped connecting rod 305 to move upward, the inverted U-shaped connecting rod 305 will drive the two opening and closing devices 307 to open; when the grooved wheel 303 drives the inverted U-shaped connecting rod 305 to move downward, the inverted U-shaped connecting rod 305 will drive the two opening and closing devices 307 to close). This ensures that the chive seeds fall into the soil at the same distance.

[0065] Specifically, see Figure 24 and Figure 25 As an optional implementation of each soil covering mechanism 500: each soil covering mechanism 500 includes a third motor 501, a second small sprocket 502, a second large sprocket 503, a second chain 504, a third connecting shaft 505, a soil covering wheel 506, a front support 507 for the soil covering wheel, and a rear support 508 for the soil covering wheel; the third motor 501 is fixedly mounted on the frame 100, the second small sprocket 502 is fixedly mounted on the output shaft of the third motor 501, the second large sprocket 503 is fixedly mounted on the rear end of the third connecting shaft 505, and one end of the second chain 504 is sleeved on the second small sprocket 502, and the other end... The soil covering wheel 506 is fixedly installed on the third connecting shaft 505 and the second large sprocket 503 is fitted on the second large sprocket 503. The lower end of the soil covering wheel rear bracket 508 is fitted on the third connecting shaft 505 and is located between the second large sprocket 503 and the soil covering wheel 506. The upper end of the soil covering wheel rear bracket 508 is fixedly connected to the frame 100. The lower end of the soil covering wheel front bracket 507 is fitted on the front end of the third connecting shaft 505 and rotates with the third connecting shaft 505 through the second bearing 509. The upper end of the soil covering wheel front bracket 507 is fixedly connected to the frame 100.

[0066] Specifically, as another optional implementation of each soil covering mechanism 500: each soil covering mechanism 500 includes a third motor 501, a second small pulley, a second large pulley, a second synchronous belt, a third connecting shaft 505, a soil covering wheel 506, a soil covering wheel front support 507, and a soil covering wheel rear support 508; the third motor 501 is fixedly mounted on the frame 100, the second small pulley is fixedly mounted on the output shaft of the third motor 501, the second large pulley is fixedly mounted on the rear end of the third connecting shaft 505, and one end of the second synchronous belt is sleeved on the third connecting shaft 506. The soil covering wheel 506 is fixedly installed on the third connecting shaft 505. The lower end of the soil covering wheel rear bracket 508 is fitted on the third connecting shaft 505 and located between the second large pulley and the soil covering wheel 506. The upper end of the soil covering wheel rear bracket 508 is fixedly connected to the frame 100. The lower end of the soil covering wheel front bracket 507 is fitted on the front end of the third connecting shaft 505 and rotates with the third connecting shaft 505 through the second bearing 509. The upper end of the soil covering wheel front bracket 507 is fixedly connected to the frame 100.

[0067] When soil covering is required, the second small sprocket 502 (or the second small pulley) is first driven to rotate by the third motor 501. Then, the second small sprocket 502 (or the second small pulley) drives the second large sprocket 503 (or the second large pulley) to rotate via the second chain 504 (or the second synchronous belt). Next, the second large sprocket 503 (or the second large pulley) drives the third connecting shaft 505 to rotate. Then, the third connecting shaft 505 drives the soil covering wheel 506 to rotate. When the soil covering wheel 506 rotates, it can roll up the soil on both sides of the ridge. The soil rolled up by the soil covering wheel 506 can cover both sides of the film, which can play a role in fixing the film.

[0068] Specifically, see Figure 27 The guiding mechanism 400 includes a front axle 401 and two front wheels 402 rotatably disposed at the left and right ends of the front axle 401. Both ends of the front axle 401 are also connected to the frame 100.

[0069] Specifically, see Figure 26 and Figure 28 The film-coating mechanism 600 includes a film-laying rod 601, a film-laying rod rotating seat 602, a film-laying rod limiting seat 603, and a film-pressing structure 604. The film-laying rod 601, the film-laying rod rotating seat 602, and the film-laying rod limiting seat 603 are all located on the upper front end of the frame 100. One end of the film-laying rod 601 is rotatably connected to the film-laying rod rotating seat 602, and the other end is engaged with the film-laying rod limiting seat 603. The film-laying rod 601 is used to install the film-coating roll. The film-laying rod 601 can rotate around the film-laying rod rotating seat 602 about the rotation center of the film-laying rod rotating seat 602, realizing lifting and lowering. When lifted, it can separate from the film-laying rod limiting seat 603, and when lowered, it can be engaged with the film-laying rod limiting seat 603. The pressure film structure 604 is located at the lower rear end of the frame 100 and is positioned opposite to the guide mechanism 400. The pressure film structure 604 is used for pressure film. The pressure film structure 604 includes a rear wheel axle 6041 and two rear wheels 6042 that are rotatably disposed at the left and right ends of the rear wheel axle 6041. Both ends of the rear wheel axle 6041 are also connected to the frame 100.

[0070] When mulching is required, for the first mulching, the film on the film-laying rod 601 is first pulled out manually, then passed under the film-pressing structure 604 and covered the soil surface of the previously sown ridge. Then, the seeder (i.e., the leek sowing and mulching integrated machine provided by this invention) is pushed forward manually, sowing and mulching simultaneously until the current ridge is completely mulched. Afterwards, the film behind the film-pressing structure 604 is cut, and the seeder moves to the next ridge to begin the mulching operation. Since the seeder is manually propelled, it can be stopped at any time during the mulching process, and the film can be replaced as needed, or replaced when the film is exhausted.

[0071] Specifically, see Figure 6 As an optional embodiment of the frame 100: the frame 100 includes two parallel and opposite longitudinal bars 101, and a first crossbar 102, a second crossbar 103, and a third crossbar 104 are arranged sequentially from front to back between the two longitudinal bars 101. Two front wheel connecting rods 105 are arranged at the lower end of the connection between the two longitudinal bars 101 and the second crossbar 103. Two handgrip supports 107 are arranged at the upper end of the connection between the two longitudinal bars 101 and the third crossbar 104. A handgrip support connecting rod 1 is arranged between the two handgrip supports 107. 08 and a hand grip 109, with two rear wheel connecting rods 106 at the tail ends of the two longitudinal rods 101; wherein, the above-mentioned seeding mechanism 200 and sowing mechanism 300 are provided on the upper part of the first crossbar 102; the above-mentioned soil covering mechanism 500 is provided on the lower part of the second crossbar 103 and the third crossbar 104; the above-mentioned guide mechanism 400 is connected to the lower part of the two front wheel connecting rods 105; the above-mentioned film pressing structure 604 is connected to the lower part of the two rear wheel connecting rods 106; and the above-mentioned film releasing rod 601 is provided on the upper front end of the two longitudinal rods 101.

[0073] Specifically, in an optional embodiment of the soil covering mechanism 500, the transmission ratio between the second small sprocket 502 and the second large sprocket 503 is 1:2.

[0074] It should be noted that the leek sowing and mulching integrated machine provided by the present invention also includes a control panel (not shown in the figure), and the control panel is installed on the handle (i.e., the handle bar 109) of the frame 100 and is electrically connected to the first motor 212, the second motor 301 and the third motor 501 respectively, for controlling the operation of the first motor 212, the second motor 301 and the third motor 501.

[0075] The working principle of the chive sowing and mulching integrated machine provided by this invention is as follows: In use, the sowing vehicle is first manually pushed on the raised bed while simultaneously pressing the soil covering button on the control panel. This activates the soil covering mechanism 500, keeping the soil covering wheel 506 continuously rotating. Once the sowing vehicle has moved to a suitable distance, the automatic sowing button on the control panel is pressed, activating the seed distribution mechanism 200 and the sowing mechanism 300. The chive seeds are first screened and confirmed in the seed distribution mechanism 200, then pass through the seed outlet tube 208 and enter the sowing mechanism 300 below. The sowing mechanism 300 then carries the chive seeds a certain distance from the soil surface, and subsequently... The vehicle then leaves the soil layer to prepare for the next batch of chive seeds for the next sowing operation. After each sowing operation, the guiding device 400 immediately flattens the soil surface after sowing. Then, the mulching mechanism 600 automatically mulches the path traveled by the sowing vehicle to ensure that the chive seeds have a suitable growth environment. The sides of the mulched film are covered with soil rolled up by the mulching wheel 506. The above automatic sowing, automatic soil pressing and automatic mulching operations are repeated until the sowing, mulching and covering of the current row are completed. Then, the sowing vehicle is pushed to the next row to carry out the sowing, mulching and covering of the next row.

[0076] Finally, it should be noted that the above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
