Description

Technical Field

[0001] This invention relates to the field of agricultural seeding equipment technology, specifically to an adjustable equidistant agricultural seeding device and its usage method. Background Technology

[0002] Adjustable equidistant agricultural seeding device is an advanced agricultural machine. This device uses technology to create planting pits in the field according to the required row spacing of crops, and sows seeds evenly in the pits, precisely controlling the planting spacing of seeds, thereby improving crop growth quality and agricultural yield.

[0003] Adjustable equidistant agricultural seeding devices improve the flexibility and precision of seeding through built-in adjustment mechanisms. They can adjust the seeding spacing according to the characteristics and growth needs of different seeds to meet the seeding requirements of different crops.

[0004] Existing adjustable equidistant agricultural seeding devices cannot fine-tune the seeding depth in a timely manner during the seeding process. Due to the difference in seed size, the same seeding depth may result in seeds being planted too deep or too shallow, making it difficult for crops to germinate or causing plants to fall over. Stopping the machine to adjust the seeding depth will reduce work efficiency and increase the labor intensity of workers. Therefore, in order to address the above problems, an adjustable equidistant agricultural seeding device and its usage method are proposed. Summary of the Invention

[0010] As a further optimization of the present invention, the following features are provided: a plow frame is fixedly connected to the bottom of the fixed block on the frame; two fixed blocks are provided on the frame and are symmetrically distributed front and back; the rotating column, belt rotating disc and grooved rotating disc between the blocks are on the same axis; and the included angle between the capped long rod and the grooved rotating disc is 90°.

[0011] As a further optimization of the present invention, the angle between the capped rod and the stopper rod is 90°, the angle between the stopper rod and the upper limit rod of the block is 90°, one end of the upper limit rod of the block is fixedly connected to a fixed block on the frame, the central axis of the stopper rod and the central axis of the stopper head are on the same straight line, and the projection of the stopper head in the vertical direction is circular.

[0012] As a further optimization of the present invention, wherein: a capped long rod is rotatably connected to the inner side of the inter-pipe rotating groove, an upper limit rod is slidably connected to the inner side of the inter-pipe sliding groove, the bottom end of the limit ring is attached to the upper end of the clamp, two pipe bottom grooves are provided, the two pipe bottom grooves are symmetrically distributed on the bottom end of the grooved sleeve, and a duckbill plate is slidably connected to the inner side of the formed clamping plate.

[0013] As a further optimization of the present invention, the upper end of the slotted fixing block is fixedly connected to the plow frame, there are two slotted fixing blocks, the two slotted fixing blocks are symmetrically distributed front and back, the outer side of the inner sliding rod of the block is in contact with the inner side of the slotted fixing block, the bottom end of the reset spring is fixedly connected to the slotted fixing block, and the reset spring and the slotted fixing block correspond one-to-one.

[0014] As a further optimization of the present invention, the included angle between the sliding rod inside the block and the clamp is 90°, there are two sliding rods inside the block, and the two sliding rods inside the block are symmetrically distributed on the outside of the clamp, the included angle between the rotating pin and the clamp is 90°, and the included angle between the rotating pin and the duckbill plate is 90°.

[0015] As a further optimization of the present invention, wherein: one end of the transmission rod is fixedly connected to a grooved sleeve, a sliding groove between the box is slidably connected to the outside of the transmission rod, a limit ring is slidably connected to the outside of the water plug, and a plurality of through holes are provided, each of the through holes being parallel to each other.

[0016] As a further optimization of the present invention, wherein: S1: the seed box assembly sorts the seeds during the equidistant sowing process: the position of the inner wheel with the rod in the wheel axle is adjusted to change the rolling radius of the wheel axle, the wheel axle rotates to drive the screening wheel to rotate, the seeds soaked in the filter bucket are put into the inclined groove, and the screening wheel will rotate and transport the seeds rolling down from the inclined surface of the inclined groove in batches to the discharge nozzle.

[0017] S2: The seed pressing component pushes the crop seeds downward to plant them: The wheel shaft rotates, which drives the belt rotating disk to rotate through the belt. The belt rotating disk drives the grooved rotating disk to rotate through the inter-block rotating column. The rotation of the grooved rotating disk drives the capped rod to move downward. The movement of the capped rod drives the stopper rod to move. The movement of the stopper rod drives the stopper head to move. The movement of the stopper head squeezes the crop seeds downward.

[0018] S3: The hole-digging component controls the depth and size of the planting hole: When the stopper squeezes the crop seeds downwards, the different sizes of the crop seeds result in different widths of the duckbill plate. The width of the duckbill plate affects the size of the planting hole. At the same time, due to the different seed volumes, the time it takes for the stopper to work downwards on the duckbill plate through the seeds is also different. The downward pressure on the duckbill plate is transmitted to the sliding rod inside the block through the rotating pin and the clamp. The sliding rod inside the block compresses the return spring to adjust the planting depth.

[0019] S4: Transmission and reset of the moving sleeve assembly between devices: When the duckbill plate is opened, it squeezes the clamping plate, causing the clamping plate to move. When the clamping plate moves upward, it drives the grooved sleeve to move upward. The movement of the grooved sleeve will drive the transmission rod fixedly connected on one side to move. At the same time, the inter-tube rotation groove and inter-tube sliding groove opened on the outside of the grooved sleeve can prevent the grooved sleeve from obstructing other components. When the plug moves to the top, the grooved sleeve falls due to its own weight, and at the same time, the clamping plate drives the duckbill plate to close.

[0020] S5: The water tank assembly irrigates the planted crops: unscrew the cap and inject water into the tank through the nozzle. As the transmission rod moves relative to the grooved sleeve according to the distance it moves, the transmission rod moves and drives the water plug to slide in the limiting ring. When the water plug slides upward, the water inside the tank will flow out from the through hole and flow to the ground through the sprinkler hole. The different distances the water plug moves result in different numbers of through holes that can be opened, thus affecting the amount of water used for irrigation.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the planting component allows the device to adjust the depth of the planting pit according to the size of the seeds during the sowing process without stopping the machine or requiring manual intervention. This ensures that the seeds are sown at the most suitable depth, avoiding germination difficulties or plant lodging caused by unsuitable planting pits, thus ensuring work efficiency and reducing the labor intensity of workers.

[0023] 2. In this invention, the water tank component makes irrigation more convenient and efficient. By controlling the movement of the water plug, the amount of water for irrigation can be precisely controlled, avoiding the water waste and uneven soil moisture caused by traditional flood irrigation. This helps to maintain the optimal soil moisture content and promotes rapid seed germination and healthy growth.

[0024] 3. In this invention, the seed box assembly allows seeds to be screened and disinfected before sowing. Then, the seed pressing assembly applies precise pressure to the seeds, pushing them evenly into the soil. This increases the seed contact area, ensuring good contact between the seeds and the soil, which is beneficial for the seeds to absorb water and nutrients, thereby improving the survival rate and growth quality of the crops.

[0049] As a further technical solution for this implementation, a capped long rod 515 is rotatably connected to the inner side of the pipe rotating groove 522, an upper limit rod 517 is slidably connected to the inner side of the pipe sliding groove 523, the bottom end of the limit ring 524 is attached to the upper end of the clamp 534, two pipe bottom grooves 525 are provided, and the two pipe bottom grooves 525 are symmetrically distributed on the bottom end of the grooved sleeve 521. A duckbill piece 536 is slidably connected to the inner side of the formed clamping plate 526.

[0050] As a further implementation of this solution, a plow frame 1 is fixedly connected to the upper end of the slotted fixing block 531.

[0052] As a further implementation of this scheme, a grooved sleeve 521 is fixedly connected to one end of the transmission rod 61, a sliding groove 642 between the box is slidably connected to the outside of the transmission rod 61, a limit ring frame 645 is slidably connected to the outside of the water plug 63, and several through holes 644 are provided, with each through hole 644 being parallel to each other. This design is more reasonable and helps to improve the accuracy of the device operation.

[0053] S1: Seeding box assembly 4 sorts seeds during equidistant sowing: Adjusting the position of inner wheel 3 in axle 2 changes the rolling radius of axle 2. Axle 2 rotates, driving screening wheel 43 to rotate. Seeds soaked in filter hopper 42 are placed into inclined trough 413. Screening wheel 43 will rotate and transport the seeds rolling down the inclined surface of inclined trough 413 in batches to discharge nozzle 415.

[0054] S2: The seed pressing component 51 pushes the crop seeds downward to plant them: The rotation of the wheel axle 2 drives the belt rotating disk 513 to rotate through the belt. The belt rotating disk 513 drives the grooved rotating disk 514 to rotate through the inter-block rotating column 512. The rotation of the grooved rotating disk 514 drives the capped long rod 515 to move downward. The movement of the capped long rod 515 drives the stopper rod 516 to move. The movement of the stopper rod 516 drives the stopper head 518 to move. The movement of the stopper head 518 squeezes the crop seeds downward.

[0055] S3: The digging component 53 controls the digging depth and size of the planting hole: When the plug 518 squeezes the crop seeds downwards, the different sizes of the crop seeds result in different widths of the duckbill plate 536. The width of the duckbill plate 536 affects the size of the planting hole. At the same time, due to the different seed volumes, the duration for which the plug 518 applies downward work to the duckbill plate 536 through the seeds is also different. The downward pressure on the duckbill plate 536 is transmitted to the sliding rod 532 inside the block through the rotating pin 535 and the clamp 534. This causes the sliding rod 532 inside the block to compress the return spring 533, thereby adjusting the planting depth.

[0056] S4: Transmission and reset of the movable sleeve assembly 52 between devices: When the duckbill plate 536 is opened, it squeezes the clamping plate 526, causing the clamping plate 526 to move. When the clamping plate 526 moves upward, it drives the grooved sleeve 521 to move upward. The movement of the grooved sleeve 521 will drive the transmission rod 61 fixedly connected on one side to move. At the same time, the inter-tube rotation groove 522 and inter-tube sliding groove 523 opened on the outside of the grooved sleeve 521 can prevent the grooved sleeve 521 from obstructing other components. When the plug 518 moves to the uppermost position, the grooved sleeve 521 falls due to its own weight, and at the same time, the clamping plate 526 drives the duckbill plate 536 to close.

[0057] S5: Water tank assembly 6 irrigates the planted crops: unscrew the cap 65 and inject water into the inner groove 643 of the tank through the tank nozzle 647. Since the transmission rod 61 moves relative to the grooved sleeve 521 according to the moving distance, the movement of the transmission rod 61 drives the water-blocking plug 63 to slide in the limiting ring 645. When the water-blocking plug 63 slides upward, the water inside the inner groove 643 will flow out from the through hole 644 and flow to the ground through the sprinkler hole 646. The different moving distances of the water-blocking plug 63 result in different numbers of through holes 644 that can be unobstructed, thus affecting the amount of water for irrigation.
