Description

Technical Field

[0001] The present invention relates to the technical field of agricultural production, and specifically relates to a synchronous heterolayer fertilizing and seeding machine for planting in sandy soil. Background Art

[0002] The synchronous heterolayer fertilizing and seeding machine simultaneously applies seeds and fertilizers into the soil through a mechanical device, but the fertilizer and seeds are located in different soil layers. Generally, the fertilizer is applied in a deeper soil layer, while the seeds are sown in a shallower soil layer. This way of layered fertilization can reduce the direct contact between the fertilizer and the seeds, avoid the phenomenon of seedling burning, and at the same time ensure that the fertilizer is gradually absorbed during the growth process of the crop roots.

[0003] In the prior art, when the synchronous heterolayer fertilizing and seeding machine performs fertilizing and seeding, the seeds and fertilizers generally continuously enter the seed furrow, and it is impossible to adjust the seeding interval.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0030] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 8 , a synchronous different-layer fertilizing and seeding machine for sandy soil planting, including a support plate 7. Symmetrically distributed rotating shafts 9 are provided at the bottom of the support plate 7, and traveling wheels 8 are fixed to the ends of the rotating shafts 9. The rotating shafts 9 are rotatably connected to a fixing frame 12, and the fixing frame 12 is fixedly connected to the support plate 7. A fertilizer box 1, a seed box 3, and a soil box 2 penetrate through the inside of the support plate 7. The fertilizer box 1, the seed box 3, and the soil box 2 are all fixedly connected to the support plate 7, and the soil box 2 is located between the seed box 3 and the fertilizer box 1. First arc-shaped frames 10 and second arc-shaped frames 11 are integrally formed at the bottoms of the fertilizer box 1 and the seed box 3 respectively. A fertilizing mechanism 4 and a seeding mechanism 5 are respectively provided inside the first arc-shaped frame 10 and the second arc-shaped frame 11. The fertilizing mechanism 4 is used to control fertilization, and the seeding mechanism 5 is used to control seeding. A layering mechanism 6 is provided inside the soil box 2, and the layering mechanism 6 is used to layer the seeds and fertilizers.

[0031] In this embodiment, when this fertilizing and seeding machine is in use, fertilizers, seeds, and soil are respectively poured into the fertilizer box 1, the seed box 3, and the soil box 2. The support plate 7 is driven by the vehicle body to move, or the support plate 7 can also be pushed manually. While the support plate 7 moves, it drives the traveling wheels 8 to roll on the ground. While the traveling wheels 8 roll, they drive the rotating shafts 9 to rotate. While the rotating shafts 9 rotate, they drive the fertilizing mechanism 4, the layering mechanism 6, and the seeding mechanism 5 to operate. Under the action of the fertilizing mechanism 4, the fertilizer falls into the seed furrow through the feeding port at the bottom of the fertilizer box 1. Subsequently, under the action of the layering mechanism 6, the soil falls into the seed furrow through the opening at the bottom of the soil box 2 and covers the fertilizer. Finally, under the action of the seeding mechanism 5, the seeds fall above the soil through the opening at the bottom of the seed box 3. The soil discharged from the soil box 2 layers the fertilizer and the seeds, so that the fertilizer and the seeds are respectively applied to different depths of the seed furrow, thereby improving the utilization rate of the fertilizer and the yield of the crops.

[0032] Please refer to Figures 1 - 4, the fertilizer application mechanism 4 includes a first rotating roller 44 rotatably connected to the inner wall of the first arc-shaped frame 10. Both ends of the first rotating roller 44 are fixed with first rotating columns 43. The first rotating columns 43 are rotatably connected to a first support 414. The first support 414 is fixedly connected to the support plate 7. Among them, the first rotating column 43 is connected to a first rotating assembly, and the first rotating assembly is used to drive the first rotating column 43 to rotate. A plurality of fertilizer grooves 410 distributed in a circumferential manner are provided on the side wall of the first rotating roller 44. Two arc-shaped baffles 45 are symmetrically distributed and slidably connected to the outside of the first arc-shaped frame 10. One end of the arc-shaped baffle 45 penetrates the side wall of the first arc-shaped frame 10 and is slidably connected to the side wall of the first arc-shaped frame 10. The other end of the arc-shaped baffle 45 is connected to a traction assembly, and the traction assembly is used to traction the arc-shaped baffle 45, so as to change the distance between the two arc-shaped baffles 45;

[0033] As the rotating shaft 9 rotates, the first rotating column 43 is driven to rotate through the first rotating assembly, and the first rotating column 43 drives the first rotating roller 44 to rotate. The first rotating roller 44 drives the fertilizer trough 410 on its side wall to move in a circular motion. When one of the fertilizer troughs 410 rotates to the top, the fertilizer inside the fertilizer box 1 can fall into the fertilizer trough 410 through the discharge port at the bottom thereof. As the first rotating roller 44 continues to rotate, the first rotating roller 44 drives the fertilizer inside the fertilizer trough 410 to move in a circular motion. When the fertilizer trough 410 containing the fertilizer rotates, the fertilizer inside the fertilizer trough 410 is rotated. When the fertilizer reaches the bottom, the fertilizer directly passes through the opening at the bottom of the first arc frame 10 under the action of gravity and falls into the seed trench. This cycle is repeated, so that the fertilizer in the fertilizer box 1 can continuously enter the seed trench, thereby achieving the purpose of continuous fertilization and ensuring that the fertilizer is evenly distributed throughout the operation process. It can provide a stable nutrient supply for crops, promote the continuous growth and development of crops, and improve the stress resistance and yield of crops. In addition, an arc baffle 45 is passed through the side wall of the first arc frame 10. In actual application, the arc baffle can be pulled by the traction component. The plate 45 is pulled, thereby changing the distance between the two arc-shaped baffles 45, thereby regulating the width of the fertilizer trough 410 leaking out, and regulating the amount of fertilizer entering the fertilizer trough 410, so that the device can be suitable for the fertilizer needs of different crops. For example, when the demand for fertilizer of the crops is large, the distance between the arc-shaped baffles 45 is large. When the fertilizer trough 410 rotates to the highest position, the width of the fertilizer trough 410 leaking out is large, thereby allowing more fertilizer to enter the fertilizer trough 410. At this time, when the rotating roller rotates one circle, more fertilizer can fall. The first rotating component includes a first pulley 42 fixed to the end of one of the first rotating columns 43 and the outside of one of the rotating shafts 9. The first pulley 42 is connected by a first belt 41. When the rotating shaft 9 rotates, the first rotating column 43 is driven to rotate through the first pulley 42 and the first belt 41, and then the first rotating roller 44 is driven to rotate. The first rotating roller 44 is driven by the rotation of the rotating shaft 9. No additional power supply is required, thereby saving energy.

[0034] See also Figures 3 - 5, the traction assembly includes a connecting plate 46 fixedly connected to the end of the arc-shaped baffle 45. The connecting plate 46 is fixedly connected with an arc-shaped rod 411. The arc-shaped rod 411 is provided on the outer wall of the first arc-shaped frame 10. The arc-shaped rod 411 penetrates through the limiting plate 413 and is slidably connected with the limiting plate 413. A first elastic member 412 is arranged outside the arc-shaped rod 411. Two ends of the first elastic member 412 are respectively fixedly connected with the connecting plate 46 and the limiting plate 413. A rotating rod 49 penetrates through the first support 414, and the rotating rod 49 is rotatably connected with the first support 414. A winding roller 47 is fixed to the outside of the rotating rod 49. The winding roller 47 is fixedly connected with a traction rope 48. The traction rope 48 passes through the inside of the limiting plate 413 and is fixedly connected with the connecting plate 46. A positioning disk 418 is fixed to the outside of the rotating rod 49. A first pin rod 415 penetrates through the positioning disk 418. The first pin rod 415 is connected with the positioning disk 418 through a second elastic member 416. A plurality of first pin slots 417 adapted to the first pin rod 415 and distributed in a circular pattern are arranged on the surface of the first support 414;

[0035] When it is necessary to control the amount of fertilizer discharged, the rotating rod 49 is rotated to drive the winding roller 47 to rotate. While the winding roller 47 rotates, the two arc-shaped baffles 45 are pulled through the traction rope 48 and the connecting plate 46, so as to increase the distance between the two arc-shaped baffles 45, and further increase the amount of fertilizer entering the fertilizer tank 410. When it is necessary to reduce the distance between the two arc-shaped baffles 45, the rotating rod 49 rotates in the reverse direction, and the traction force of the winding roller 47 on the connecting plate 46 through the traction rope 48 is reduced. The arc-shaped baffle 45 gradually resets under the action of the first elastic member 412, so as to reduce the amount of fertilizer entering the fertilizer tank 410. In addition, when the rotating rod 49 is rotated, the first pin rod 415 can be pulled out from the inside of the first pin slot 417. When the position of the arc-shaped baffle 45 is adjusted, the first pin rod 415 is released. The first pin rod 415 automatically enters into one of the first pin slots 417 under the action of the second elastic member 416. The first pin slot 417 fixes the rotating rod 49 through the first pin rod 415 and the positioning disk 418, thereby effectively ensuring the stability of the arc-shaped baffle 45. The first elastic member 412 and the second elastic member 416 can both be springs. The limiting plate 413 can limit the connecting plate 46 through the arc-shaped rod 411, effectively improving the stability of the arc-shaped baffle 45 during movement.

[0036] Please refer to Figure 1 , Figure 6 and Figure 7The sowing mechanism 5 includes a second rotating roller 59 rotatably connected to the inner wall of the second arc-shaped frame 11, and second rotating columns 54 are fixed at both ends of the second rotating roller 59. The second rotating column 54 is rotatably connected to the second bracket 53, and the second bracket 53 is fixedly connected to the support plate 7, wherein the second rotating column 54 is connected to a second rotating component, and the second rotating component is used to drive the second rotating column 54 to rotate, and a plurality of seed grooves 511 distributed in a circumference are provided on the side wall of the second rotating roller 59, and arc-shaped stoppers 512 are slidably connected inside the seed grooves 511, wherein the arc-shaped stoppers 512 are connected to a driving component on one side close to the inner wall of the seed groove 511, and the driving component is used to drive the arc-shaped stoppers 512 to move, so that the outer surface of the arc-shaped stoppers 512 is flush with the outer surface of the second rotating roller 59;

[0037] When the rotating shaft 9 rotates, the second rotating column 54 is driven to rotate through the second rotating component, and the second rotating column 54 drives the second rotating roller 59 to rotate. The second rotating roller 59 drives the seed groove 511 on its side wall to move in a circular motion. When one of the seed grooves 511 rotates to the top, the seeds inside the seed box 3 can fall into the seed groove 511 through the discharge port at its bottom. As the second rotating roller 59 continues to rotate, the second rotating roller 59 drives the seeds inside the seed groove 511 to move in a circular motion. When the seed groove 511 containing the seeds rotates to the bottom, the seeds pass directly through the opening at the bottom of the second arc frame 11 under the action of gravity and fall into the seed groove, thereby achieving the purpose of sowing. The seed groove 511 is provided with an arc stopper 512. When sowing, the arc stopper 512 can be driven by the driving component to move, so that the arc stopper 512 blocks the seed groove 511. For example, the number of the seed grooves 511 can be four , the driving component drives the arc-shaped block 512 inside the two opposite seed grooves 511 to move, so that the arc-shaped block 512 blocks the corresponding seed groove 511. When the seed groove 511 rotates to the top, under the blocking of the arc-shaped block 512, the seeds inside the seed box 3 will not enter the seed groove 511, thereby achieving the purpose of intermittent sowing. The sowing interval and density can be adjusted according to specific needs, so as to be suitable for different crops and planting patterns. The second rotating component includes a second pulley 51 fixed to the end of one of the second rotating columns 54 and the outside of one of the rotating shafts 9. The second pulley 51 is connected by a second belt 52. When the rotating shaft 9 rotates, the second rotating column 54 is driven to rotate by the second pulley 51 and the second belt 52, thereby driving the second rotating roller 59 to rotate. The second rotating roller 59 is driven to rotate by the rotation of the rotating shaft 9. No additional power supply is required, thus saving energy.

[0038] See also Figure 6 and Figure 7, the driving component includes air cavities 515 arranged on the side wall of the second rotating roller 59. The air cavities 515 are arranged staggeredly. The air cavities 515 communicate with the seed grooves 511 through air holes 514. Pistons 516 are slidably connected inside the air cavities 515. The pistons 516 are fixedly connected with support rods 517. One end of the support rod 517 away from the piston 516 is fixed with a push plate 519. The push plate 519 is connected with the inner wall of the second rotating roller 59 through a third elastic member 518. One side of the arc-shaped stopper 512 close to the inner wall of the seed groove 511 is fixed with a fourth elastic member 513. The other end of the fourth elastic member 513 is fixedly connected with the inner wall of the seed groove 511. A pushing component is arranged inside the second rotating roller 59. The pushing component is used to push a plurality of push plates 519 in sequence;

[0039] When it is necessary to adjust the sowing interval, the push plate 519 is pushed through the pushing component. Since the air cavities 515 are arranged staggeredly, the push plates 519 are also distributed staggeredly. The pushing component first pushes two of the push plates 519. The push plates 519 compress the gas inside the air cavities 515 through the support rods 517 and the pistons 516. The gas enters the corresponding seed grooves 511 through the air holes 514. The air pressure inside the seed grooves 511 increases, so that the arc-shaped stopper 512 moves outwards and seals the seed grooves 511, making the seeds unable to enter the seed grooves 511, thereby increasing the sowing interval of the seeds. When it is necessary to further increase the sowing interval, the remaining push plates 519 are pushed through the pushing component, so that the gas inside the remaining air cavities 515 can enter the corresponding seed grooves 511, and then the remaining arc-shaped stoppers 512 can also seal their corresponding seed grooves 511. The third elastic member 518 can play a reset role for the push plate 519, and the fourth elastic member 513 can play a reset role for the arc-shaped stopper 512. The third elastic member 518 and the fourth elastic member 513 can be springs.

[0040] Please refer to Figure 6 , the pushing component includes a conical block 510 arranged inside the second rotating roller 59. The conical block 510 is fixedly connected with a push rod 58. The push rod 58 penetrates through the end of the second rotating roller 59 and one of the second rotating columns 54 and is slidably connected with both of them. A second pin rod 55 penetrates through the side wall of the second rotating column 54. The second pin rod 55 is connected with the side wall of the rotating column through a fifth elastic member 56. A plurality of second pin slots 57 adapted to the second pin rods 55 are arranged on the side wall of the push rod 58;

[0041] When the sowing interval needs to be increased, the push rod 58 is pushed, and the push rod 58 drives the conical block 510 to move. While the conical block 510 moves, it squeezes the push plate 519 through its inclined surface, so that the push plate 519 drives the piston 516 to squeeze the gas inside the air cavity 515 through the support rod 517, so that the arc stopper 512 can block the corresponding seed groove 511. The push rod 58 can also pull the second pin 55 out of the second pin groove 57 while moving, and then push the push rod 58 and release the second pin 55. When the conical block 510 finishes squeezing the push plate 519 that first contacts it, the second pin 55 is released. The pin rod 55 automatically enters one of the second pin grooves 57 under the action of the fifth elastic member 56, and the push rod 58 is fixed by the second pin rod 55, thereby ensuring the stability of the push rod 58. If the sowing interval needs to be further increased, the second pin rod 55 is pulled out from the second pin groove 57 again, and then the push rod 58 is pushed and the second pin rod 55 is released. When the conical block 510 completes squeezing the subsequent push plate 519 that contacts it, the second pin rod 55 automatically moves to the subsequent second pin groove 57 under the action of the fifth elastic member 56, thereby fixing the push rod 58, wherein the fifth elastic member 56 can be a spring.

[0042] See also Figure 1 and Figure 8 The stratification mechanism 6 includes a transmission rod 62 that penetrates the side wall of the soil box 2, one end of the transmission rod 62 is connected to a third rotating assembly, and the third rotating assembly is used to drive the transmission rod 62 to rotate. A plurality of partitions 61 distributed in a circumference are fixed inside the soil box 2 and outside the transmission rod 62;

[0043] During layered sowing and fertilization, the transmission rod 62 is driven to rotate by the third rotating component, and the transmission rod 62 drives the external partition 61 to move in a circular motion. The circular motion of the partition 61 controls the falling of the soil inside the soil box 2, and then the seeds and fertilizers are layered. The third rotating component includes a third pulley 63 fixed to the end of the transmission rod 62 and the outside of one of the rotating shafts 9. The third pulley 63 is connected by a third belt 64. When the rotating shaft 9 rotates, the transmission rod 62 is driven to rotate by the third pulley 63 and the third belt 64, and then the partition 61 is driven to move in a circular motion. No additional power supply is required, saving energy.

[0044] Working principle: When this fertilizer seeder is in use, fertilizers, seeds, and soil are respectively poured into the fertilizer box 1, the seed box 3, and the soil box 2. The vehicle body drives the support plate 7 to move, or the support plate 7 can also be manually pushed. While the support plate 7 is moving, it drives the walking wheels 8 to roll on the ground. While the walking wheels 8 are rolling, they drive the rotating shaft 9 to rotate. While the rotating shaft 9 is rotating, it drives the first rotating column 43, the second rotating column 54, and the transmission rod 62 to rotate. The first rotating column 43 drives the first rotating roller 44 to rotate. The first rotating roller 44 drives the fertilizer groove 410 on its side wall to move in a circular motion. When one of the fertilizer grooves 410 rotates to the uppermost position, the fertilizer in the fertilizer box 1 can fall into this fertilizer groove 410 through the feeding port at its bottom. As the first rotating roller 44 continues to rotate, the first rotating roller 44 drives the fertilizer in the fertilizer groove 410 to move in a circular motion. When the fertilizer groove 410 filled with fertilizer rotates to directly below, the fertilizer directly passes through the opening at the bottom of the first arc-shaped frame 10 under the action of gravity and falls into the seed furrow. In this way, it circulates repeatedly, enabling the fertilizer in the fertilizer box 1 to continuously enter the seed furrow, thereby achieving the purpose of continuous fertilization, ensuring that the fertilizer is evenly distributed throughout the operation process, providing a stable nutrient supply for the crops, promoting the continuous growth and development of the crops, improving the stress resistance and yield of the crops. The second rotating column 54 drives the second rotating roller 59 to rotate. The second rotating roller 59 drives the seed groove 511 on its side wall to move in a circular motion. When one of the seed grooves 511 rotates to the uppermost position, the seeds in the seed box 3 can fall into this seed groove 511 through the feeding port at its bottom. As the second rotating roller 59 continues to rotate, the second rotating roller 59 drives the seeds in the seed groove 511 to move in a circular motion. When the seed groove 511 filled with seeds rotates to directly below, the seeds directly pass through the opening at the bottom of the second arc-shaped frame 11 under the action of gravity and fall into the seed furrow, thereby achieving the purpose of sowing. The transmission rod 62 drives the partition 61 outside it to move in a circular motion. The falling of the soil inside the soil box 2 is controlled by the circular motion of the partition 61. The soil discharged from the soil box 2 stratifies the fertilizer and the seeds, so that the fertilizer and the seeds are respectively applied to different depths of the seed furrow, thereby improving the utilization rate of the fertilizer and the yield of the crops.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
