DETAILED DESCRIPTION

[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0038] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0039] Reference Figure 1-Figure 10 As shown, a vegetable planting and sowing device comprises: a base plate 100, a slotted plate 104 for slotting which is arranged on the base plate 100 and can be lifted and lowered by a lifting mechanism 200, a sowing mechanism 300 fixedly arranged on the base plate 100 and located behind the slotted plate 104 for uniform sowing, and a fertilizing mechanism 400 for quantitatively fertilizing the sown seeds; wherein, a plurality of groups of driving wheels 101 are rotatably arranged on the bottom surface of the base plate 100, and a bidirectional motor 103 is fixedly arranged on the rotating shaft of the driving wheel 101.

[0040] When in use, the bidirectional motor 103 is started, and the motor drives multiple groups of driving wheels 101 to rotate through the rotating shaft of the driving wheel 101, so that the entire sowing device can move in the farmland. According to the soil conditions of the farmland and the sowing requirements, the height of the slotted plate 104 is adjusted by the lifting mechanism 200. After the slotted plate 104 is adjusted to a suitable height, as the sowing device moves, a sowing groove of a certain depth and width will be opened in the soil. When the sowing device moves to the designated sowing position, the slotted plate 104 starts to work and opens a sowing groove in the soil. Subsequently, the sowing mechanism 300 is started to evenly sow the seeds in the opened sowing groove. After sowing is completed, the fertilization mechanism 400 starts to work, and according to the preset fertilizer amount, the fertilizer is evenly applied above or beside the seeds in the sowing groove to provide the seeds with necessary nutrients. Through mechanized operation, the integrated operation of sowing and fertilization is realized, the sowing efficiency is greatly improved, and the labor cost is reduced. By adjusting the height of the slotted plate 104 by the lifting mechanism 200, the sowing device can adapt to farmlands with different soil conditions, and the versatility and practicality of the device are improved.

[0041] Reference Figure 4-Figure 5 As shown, the lifting mechanism 200 includes: a rotating rod 201, a convex rod 203 and a vertical connecting rod 204; wherein, the rotating rod 201 is driven to rotate by a driving motor 206 on the base plate 100, and an arc groove 202 is opened on the circumferential surface of the rotating rod 201, and a vertical connecting rod 204 slidably sleeved in the base plate 100 is fixed on the upper surface of the slotted plate 104, and a convex rod 203 slidably sleeved in the arc groove 202 is fixed on the side of the vertical connecting rod 204, and a spring 205 is sleeved on the vertical connecting rod 204, and the two ends of the spring 205 are respectively abutted against the upper surface of the base plate 100 and the surface of the convex rod 203.

[0042] When the height of the slotted plate 104 needs to be adjusted, the driving motor 206 is first started, and the driving motor 206 drives the rotating rod 201 to rotate on the bottom plate 100. The circumferential surface of the rotating rod 201 is provided with arc grooves 202, which provide sliding tracks for the protruding rods 203. As the rotating rod 201 rotates, the protruding rods 203 on the side of the vertical connecting rods 204 fixed on the upper surface of the slotted plate 104 will slide along the arc grooves 202. This sliding process will change the vertical position of the protruding rod 203 relative to the base plate 100, thereby driving the vertical connecting rod 204 and the slotted plate 104 to move up and down. In the process of the protruding rod 203 sliding along the arc groove 202, the spring 205 sleeved on the vertical connecting rod 204 will play a role in buffering and adjusting the height. The two ends of the spring 205 are respectively in contact with the upper surface of the base plate 100 and the surface of the protruding rod 203. When the protruding rod 203 is at different positions of the arc groove 202, the compression degree of the spring 205 is different, thereby providing different supporting forces, so that the slotted plate 104 can stay stably at the required height. When the slotted plate 104 is adjusted to a suitable height, the driving motor 206 can be stopped. At this time, the slotted plate 104 will remain at this height, ready for subsequent sowing operations. The height of the slotted plate 104 can be flexibly adjusted to adapt to different soil conditions and sowing requirements.

[0043] Reference Figure 4-Figure 7 As shown, the sowing mechanism 300 includes: a storage box 301, a turntable 303, a first rotating shaft 304 and a discharge pipe 307; wherein, the storage box 301 is fixedly provided on the base plate 100, the bottom surface of the storage box 301 is provided with a first discharge port 302 and a turntable 303 is rotatably provided by the first rotating shaft 304 penetrating the base plate 100, the turntable 303 is provided with a second discharge port 305 matching the first discharge port 302, a third discharge port 306 matching the second discharge port 305 is provided on the side of the base plate 100 away from the first discharge port 302, a discharge pipe 307 is fixedly provided on the bottom surface of the third discharge port 306, and a driving component 700 for driving the first rotating shaft 304 to rotate so as to drive the seeds in the storage box 301 to be discharged intermittently is fixedly provided on the base plate 100.

[0044] In the above scheme, first, seeds are filled into the storage box 301. The storage box 301 is fixedly arranged on the bottom plate 100 and is used to store seeds to be sown. When the sowing device moves to the designated sowing position, the driving assembly 700 is started. The driving assembly 700 is fixedly arranged on the bottom plate 100 and is used to drive the first rotating shaft 304 to rotate. As the first rotating shaft 304 rotates, the rotating disk 303 also starts to rotate. The rotating disk 303 is provided with a second discharge port 305 that matches the first discharge port 302 on the bottom surface of the storage box 301. When the second discharge port 305 is aligned with the first discharge port 302, the seeds can flow out from the storage box 301 through the two discharge ports. When the turntable 303 continues to rotate, the second discharge port 305 moves to a position matching the third discharge port 306 on the bottom plate 100 away from the first discharge port 302, and the seeds flow through the two discharge ports into the discharge pipe 307 fixedly arranged on the bottom surface of the third discharge port 306. The discharge pipe 307 evenly sows the seeds into the seeding grooves that have been opened. Due to the intermittent rotation of the turntable 303, the seeds are discharged at a certain time interval, thereby achieving uniform sowing.

[0045] Reference Figure 6 As shown, the driving assembly 700 includes: a second driving shaft 701, a driving bevel gear 703 and a driven bevel gear 704; wherein, the second driving shaft 701 is rotatably provided on the bottom surface of the base plate 100 through a mounting seat, the driving bevel gear 703 is fixedly sleeved on the second driving shaft 701, and the driven bevel gear 704 meshing with the driving bevel gear 703 is fixedly provided on the bottom surface of the first rotating shaft 304.

[0046] In the above scheme, when it is necessary to drive the sowing mechanism 300 for sowing, the second drive shaft 701 is first started. The second drive shaft 701 is rotatably arranged on the bottom surface of the base plate 100 through a mounting seat, and is used to provide a power source. As the second drive shaft 701 rotates, the active bevel gear 703 fixedly sleeved on the second drive shaft 701 also starts to rotate, and the active bevel gear 703 is meshed with the driven bevel gear 704 fixedly arranged on the bottom surface of the first rotating shaft 304. Therefore, when the active bevel gear 703 rotates, it will drive the driven bevel gear 704 and the first rotating shaft 304 fixed thereto to rotate together, and as the first rotating shaft 304 rotates, the turntable 303 also starts to rotate. The second discharge port 305 on the turntable 303 will be aligned with the first discharge port 302 on the bottom surface of the storage box 301 and the third discharge port 306 on the base plate 100 in sequence, thereby realizing intermittent feeding and uniform sowing of seeds.

[0047] Reference Figure 3As shown, the seeding device also includes: a soil turning mechanism 600 rotatably arranged on the bottom surface of the base plate 100 and located in front of the slotted plate 104 , and the second drive shaft 701 is transmission-connected to the first drive shaft 601 in the soil turning mechanism 600 through a third transmission belt 702 .

[0048] In the above scheme, as the soil-turning mechanism 600 operates, the second drive shaft 701 is driven to rotate through the third transmission belt 702. At the same time, the soil-turning operation of the soil-turning mechanism 600 can loosen the soil, improve the air permeability and water permeability of the soil, and provide a good soil environment for the growth of seeds. Thereafter, the slotting plate 104 is driven by the lifting mechanism 200 to descend to a suitable height, ready for the slotting operation.

[0049] Reference Figure 3 As shown, the tillage mechanism 600 includes: a first driving shaft 601 and an tillage plate 602; the bottom surface of the base plate 100 is rotatably provided with a first driving shaft 601, the first driving shaft 601 is transmission-connected to the output shaft of the bidirectional motor 103 through a second transmission belt 603, and a plurality of groups of tillage plates 602 in contact with the ground are fixedly provided at intervals on its circumferential surface.

[0050] In the above scheme, as the bidirectional motor 103 is started, its output shaft starts to rotate, and through the transmission action of the second transmission belt 603, the first drive shaft 601 is driven to rotate, and a plurality of sets of tillage plates 602 are fixedly arranged at intervals on the circumferential surface of the first drive shaft 601. When the first drive shaft 601 rotates, the tillage plates 602 will also rotate and contact the ground, thereby turning and loosening the soil, which can loosen the soil, improve the air permeability and water permeability of the soil, and is conducive to the germination of seeds and the growth of crops. At the same time, tillage can also mix the nutrients and microorganisms in the soil evenly, thereby improving the fertility of the soil.

[0051] Reference Fig. 9 As shown, the fertilizing mechanism 400 includes: a fertilizing pipe 401, a spiral blade 403, a driven half gear 405 and a connecting rod 406; wherein, the bottom surface of the bottom plate 100 is located behind the discharge pipe 307 and is fixedly provided with a fertilizing pipe 401, a driven half gear 405 with a diameter larger than the fertilizing pipe 401 is rotatably provided in the fertilizing pipe 401, a plurality of groups of connecting rods 406 are fixedly provided at intervals on the inner side wall of the driven half gear 405, a second rotating shaft 402 coaxially arranged with the fertilizing pipe 401 is fixedly provided at one end of the connecting rod 406, and a spiral blade 403 is fixedly provided on the circumferential surface of the second rotating shaft 402.

[0052] When fertilizing, the second rotating shaft 402 is driven to start rotating. The spiral blades 403 fixedly arranged on the circumferential surface of the second rotating shaft 402 also rotate accordingly. The rotation of the spiral blades 403 will generate a thrust in the direction of the outlet of the fertilizer pipe 401, thereby pushing the fertilizer to move downward along the fertilizer pipe 401. At the same time, since the diameter of the driven half gear 405 is larger than the fertilizer pipe 401 and it only covers a part of the circumference of the fertilizer pipe 401, when the driven half gear 405 rotates, it will drive the second rotating shaft 402 to rotate intermittently. This intermittent rotation can control the amount of fertilizer discharged and realize quantitative fertilization. When the spiral blades 403 push the fertilizer to the outlet of the fertilizer pipe 401, the fertilizer will fall into the soil that has been sown through the outlet to complete the fertilization operation.

[0053] Reference Figure 4-Figure 9 As shown, a stirring mechanism 500 for uniformly mixing fertilizers is fixedly provided on the bottom plate 100 above the fertilizer pipe 401 .

[0054] Before sowing, different types of fertilizers and possible additives are placed in the mixing container of the stirring mechanism 500 in proportion. The different types of fertilizers and additives are fully mixed by the stirring mechanism 500 to ensure that the nutrients in the fertilizers are more balanced, thereby improving the utilization rate of the fertilizers and the absorption efficiency of the crops. The evenly mixed fertilizers are quantitatively applied and evenly spread by the fertilizing mechanism 400 to ensure that the crop roots receive even nutrient supply and promote the healthy growth of the crops.

[0055] Reference Figure 4 and Fig. 9 As shown, the stirring mechanism 500 includes: a stirring box 501, a stirring rod 503 and a stirring rod 503; wherein, the stirring box 501 is fixedly provided on the bottom plate 100 above the fertilizer pipe 401, a third rotating shaft 502 is rotatably provided in the stirring box 501, the third rotating shaft 502 is transmission-connected to the first rotating shaft 304 through a first transmission belt 505, stirring rods 503 are fixedly provided at intervals on the circumferential surface of the third rotating shaft 502, a scraper plate 504 in contact with the inner wall of the stirring box 501 is fixedly provided at one end of the stirring rod 503, and a driving half gear 404 meshing with the driven half gear 405 is fixedly provided on the bottom surface of the third rotating shaft 502.

[0056] In the above scheme, the fertilizer and additive to be mixed are placed in the mixing box 501. The mixing box 501 is fixedly arranged on the bottom plate 100, located above the fertilizer pipe 401, for storing and mixing fertilizers. The power is transmitted to the third rotating shaft 502 through the first transmission belt 505. As the third rotating shaft 502 rotates, the stirring rod 503 fixed on its circumferential surface also starts to rotate. The rotation of the stirring rod 503 fully mixes the fertilizer and additive in the mixing box 501. A scraper plate 504 is fixedly arranged at one end of the stirring rod 503, and the scraper plate 504 contacts the inner side wall of the mixing box 501. As the stirring rod 503 rotates, the scraper plate 504 will scrape along the inner side wall of the mixing box 501 to ensure that the fertilizer attached to the box wall is also fully mixed.

[0057] The bottom surface of the third rotating shaft 502 is fixed with a driving half gear 404, which meshes with a driven half gear 405 in the fertilizing mechanism 400. When the third rotating shaft 502 rotates, the driving half gear 404 drives the driven half gear 405 to rotate intermittently, thereby achieving quantitative fertilization of the fertilizing mechanism 400.

[0058] Reference Figure 1-Figure 2 As shown, a push handle 102 is fixedly disposed on the upper surface of the base plate 100 and a plurality of sets of covering plates 105 are fixedly disposed at intervals on the side thereof away from the trough plate 104 .

[0059] In the above scheme, the sowing personnel hold the push handle 102 and push the sowing device into the field. As the sowing device moves, the seeds are evenly spread in the soil through the feeding pipe 307 of the sowing mechanism 300. When the seeds are spread, the sowing device continues to move. At this time, the covering plate 105 fixed on the side of the bottom plate 100 will contact the soil and gently cover the sown seeds with soil, which is conducive to the germination and growth of the seeds.

[0060] In summary, the vegetable planting and sowing device provided by the present invention, when in use, starts the bidirectional motor 103, so that the entire sowing device can move in the farmland, and according to the soil conditions of the farmland and the sowing requirements, starts the driving motor 206, and the driving motor 206 drives the rotating rod 201 to rotate on the bottom plate 100. As the rotating rod 201 rotates, the convex rod 203 on the side of the vertical connecting rod 204 fixed on the upper surface of the slotted plate 104 will slide along the arc groove 202. This sliding process will change the vertical position of the convex rod 203 relative to the bottom plate 100, thereby driving the vertical connecting rod 204 and the slotted plate 104 to move up and down, adjusting the slotted plate 104 to a suitable height, and as the sowing device moves, a sowing groove of a certain depth and width will be opened in the soil, and then the first rotating shaft 304 is driven to rotate to drive the turntable 303 to start rotating. When the second discharge port 305 is aligned with the first discharge port 302, the seeds can flow out from the storage box 301 through the two discharge ports. When the turntable 303 continues to rotate, the second discharge port 305 moves to a position matching the third discharge port 306 on the bottom plate 100 away from the first discharge port 302, and the seeds flow into the discharge pipe 307 fixedly arranged at the bottom of the third discharge port 306 through the two discharge ports. The discharge pipe 307 evenly sows the seeds into the seeding groove that has been opened. Due to the intermittent rotation of the turntable 303, the seeds are discharged at a certain time interval, thereby achieving uniform sowing. Then, the spiral blade 403 fixedly arranged on the circumferential surface of the second rotating shaft 402 also rotates accordingly. The rotation of the spiral blade 403 will generate a thrust in the direction of the outlet of the fertilizer pipe 401, thereby pushing the fertilizer to move downward along the fertilizer pipe 401. This intermittent rotation can control the amount of fertilizer to be fed and realize quantitative fertilization. When the spiral blade 403 pushes the fertilizer to the outlet of the fertilizer pipe 401, the fertilizer will fall into the soil that has been sown through the outlet, completing the fertilization operation, and the planting device continues to move. At this time, the covering plate 105 fixed on the side of the bottom plate 100 will contact the soil and gently cover the sown seeds with the soil, which is conducive to the germination and growth of the seeds.
