Description

Technical Field

[0001] The present invention relates to the technical field of wheat seeding equipment, and in particular to an adjustable dryland wheat seeding device. Background Art

[0002] Dryland wheat refers to wheat cultivated relying on natural precipitation in arid and semi-arid regions. When sowing dryland wheat, since the soil conditions in the planting areas of dryland wheat are often complex, a seeding device is used to perform the seeding operation on dryland wheat. The seeding device can be adjusted according to different soil conditions and climatic environments, such as adjusting the seeding depth, row spacing, etc., to meet the requirements of complex environments.

[0003] When planting is required for some cultivated lands of mountain terraces, it is difficult for automated dryland wheat seeding devices to drive into the deep mountains for seeding work. Therefore, a hand-pushed dryland wheat seeding device is needed to perform the seeding operation on wheat.

[0004] When the existing hand-pushed dryland wheat seeding device performs the seeding operation, generally a seeding mechanism is used to perform the seeding operation on wheat seeds. When the seeding mechanism performs the seeding operation on the seeds, the planting distance is fixed, and it is difficult to quickly adjust to meet different soil conditions and climatic environments for seeding operations, which may cause problems such as over-seeding or uneven fertilization. Summary of the Invention

[0023] As a further description of an adjustable dryland wheat seeding device of the above technology:

[0024] One side of the fixed frame is fixedly connected with a collection box, an inclined plate is fixedly connected to the inside of the collection box, the inclined plate is rotatably connected to the inner wall of the rotating rod, and one end of the inclined plate is fixedly connected to the fixed frame.

[0025] To sum up, due to the adoption of the above technology of an adjustable dryland wheat seeding device, the beneficial effects of the present invention are as follows:

[0026] 1. By providing a rotating disk and a moving component, when in use, the user pushes the fixed frame to drive the wheel to rotate. The wheel rotates and drives the rotating rod to rotate. The rotating rod drives the rotating disk to rotate. The rotating disk drives the driving groove to rotate. The driving groove moves to the feeding port for material receiving operation. Then the driving groove moves away from the feeding port, and the rotating disk seals the feeding port. Then the driving groove rotates to the discharging port for discharging operation. This process is repeated, and the wheat seeds can be sown intermittently. Through the periodic cooperation of the driving groove on the rotating disk with the feeding port and the discharging port, the device ensures that the seeds are put as needed, avoiding the problem of uneven plant spacing caused by traditional continuous seed metering.

[0027] 2. By providing a rotating plate and a driving component, initially, the planting spacing is in the first gear, and the moving frame slides on the positioning rod. When it is necessary to adjust the planting distance between seeds in the second gear, the moving frame moves to the first scale line on the positioning rod, so that the moving frame drives the moving plate to move. The moving plate drives the first convex block to move. The first convex block slides and presses the moving rod, so that the moving rod drives the fixed rod to slide outward from the driving groove. The fixed rod drives the rotating plate to slide outward from the driving groove, and the rotating plate can adjust the depth of the driving groove, making it difficult for the seeds to fall into the inside of the driving groove. Therefore, the interval distance between the seeds falling into the driving groove increases, and the spacing between the seeds driven by the driving groove also increases. When adjusting the planting distance of seeds in the third gear, repeat the above operation. Through the positioning of the moving frame on the first and second scale lines of the positioning rod, the device realizes stepless adjustment of the planting spacing in the first, second, and third gears, adapts to the requirements of different wheat varieties and planting densities, can adapt to different soil conditions and climatic environments, and improves the flexibility of the equipment.

[0028] 3. By providing an adjustment component, when the rotating plate closes the groove, there will be seeds remaining inside the groove. At this time, when the rotating plate moves outward from the groove, the moving rod drives the spiral groove to rotate. The spiral groove rotates and is limited by the limiting rod, enabling the moving rod to rotate during its upward movement. The moving rod rotates and drives the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, causing the second bevel gear to drive the rotating plate on the connecting rod to rotate. The rotating plate flips and rotates the seeds on its upper surface to the inner lower surface of the groove. The seeds slide into the discharge rack through the inclined block, then slide into the connecting rod through the discharge rack, and finally slide into the collection box through the inclined plate inside the connecting rod for storage and collection operations. This device can automatically remove the residual seeds in the groove when the moving plate closes the groove, preventing the residual seeds from hindering the movement of the rotating plate and making it difficult for the rotating plate to close the groove, thus avoiding the problem of uneven seeding spacing. At the same time, the residual seeds are effectively collected into the collection box and can be reused for seeding, reducing seed waste. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0044] As Figures 1-12 shown, the present invention provides: an adjustable dryland wheat seeding device, including a bracket assembly 10, a moving assembly 20 and a sowing assembly 30 are installed on the bracket assembly 10, the bracket assembly 10 includes a fixed frame 11, the rotating rod 21 is rotatably connected to the fixed frame 11, the plow blade 13 and the soil covering plate 14 are respectively fixedly connected to the fixed frame 11 by bolts, and the plow blade 13 is located in front of the soil covering plate 14.

[0045] As Figure 6 and Figure 10 shown, the moving assembly 20 includes a rotating rod 21, a plurality of material dropping holes 211 are provided on the rotating rod 21, a wheel 22 is also fixedly connected to the rotating rod 21, and the wheel 22 is located on one side of the material dropping hole 211, and the inner wall of the material dropping hole 211 is fixedly connected to the discharge rack 325.

[0046] As Figure 2 and Figure 3As shown, the sowing assembly 30 includes a sowing rack 31, the sowing rack 31 is rotatably connected to a rotating disk 32, a plurality of grooves 321 are arranged inside the rotating disk 32, the sowing rack 31 includes a feed port 311, one end of the feed port 311 is fixedly connected to a hopper 316, and a discharge port 312 is arranged on one side of the sowing rack 31.

[0047] Specifically, when the device needs to be used for sowing operations, the seeds are poured into the hopper 316, and the user holds the handle to push the fixed frame 11 to move, and the fixed frame 11 drives the plow 13 to reclaim the dry land, and then the fixed frame 11 drives the wheel 22 to rotate, and the wheel 22 drives the rotating rod 21 to rotate, and the rotating rod 21 drives the rotating disk 32 inside the sowing frame 31 to rotate synchronously, and the rotating disk 32 drives the groove 321 to rotate, and the groove 321 rotates to the feed port 311, and the hopper 316 is opened, so that the seeds slide into the inside of the groove 321, and the groove 321 continues to rotate and rotates to the discharge port 312, and the seeds slide out of the groove 321 and slide into the soil through the discharge port 312, and then the covering plate 14 pushes the soil to cover the seeds, and then repeats the above operations to complete the seed planting operation;

[0048] The device ensures that seeds are put in as needed through the periodic coordination of the groove 321 on the rotating disk 32 with the feed port 311 and the discharge port 312, thereby avoiding the problem of uneven plant spacing caused by traditional continuous seeding.

[0049] like Figure 8 and Figure 9 As shown, an adjusting component 40 is arranged inside the groove 321, and the adjusting component 40 includes a fixed rod 41 slidably connected inside the groove 321, and one end of the fixed rod 41 is rotatably connected to a rotating plate 43, and a driving component 50 is arranged inside the sowing rack 31, and the adjusting component 40 also includes a moving rod 42 inside the fixed rod 41, and a spiral groove 421 is arranged on the surface of the moving rod 42, and a limiting rod 323 is slidably connected inside the spiral groove 421, and one end of the limiting rod 323 is fixedly connected to an inclined block 322, and a spring 33 is fixedly connected between the moving rod 42 and the rotating disk 32.

[0050] like Figure 9 As shown, one end of the moving rod 42 is fixedly connected to the first bevel gear 422, the interior of the rotating plate 43 is fixedly connected to the connecting rod 431, one end of the connecting rod 431 is fixedly connected to the second bevel gear 432, the first bevel gear 422 and the second bevel gear 432 are meshed with each other, and the connecting rod 431 is internally rotatably connected to the fixed rod 41.

[0051] like Figure 3 , Figure 4 , Figure 7, Figure 11 and Figure 12 As shown in Figure 11 and Figure 12 , the driving assembly 50 includes a moving frame 52 slidably connected to one side of the sowing frame 31. One side of the moving frame 52 is rotatably connected to a moving plate 51. A plurality of chutes are provided inside the moving plate 51. One ends of the moving rods 42 are respectively slidably connected to the inner walls of the chutes. A first convex block 511 is fixedly connected inside the chutes. A second convex block 512 is provided on one side of the first convex block 511. A third convex block 513 is provided on one side of the second convex block 512. The second convex block 512 and the third convex block 513 are respectively fixedly connected in the chutes. The length of the first convex block 511 is greater than the length of the second convex block 512. The length of the second convex block 512 is greater than the length of the third convex block 513.

[0052] By driving the driving assembly 50 to drive the moving rods 42 and the rotating plate 43 to slide inside the groove 321, the rotating plate 43 can block part of the groove 321, so that the distance between the remaining open grooves 321 changes, and thus the planting distance can be adjusted. When the rotating plate 43 slides in the groove 321, the adjusting assembly 40 drives the rotating plate 43 to rotate inside the groove 321, so that the seeds accumulated inside the groove 321 can slide to the bottom of the groove 321 and be discharged.

[0053] Specifically, when the existing dryland wheat sowing device performs sowing operations, it generally uses a sowing mechanism to sow wheat seeds. When the sowing mechanism sows seeds, its planting distance is fixed, and it is difficult to quickly adjust to meet different soil conditions and climate environments for sowing operations, which may cause problems such as over-sowing or uneven fertilization.

[0054] To solve the above problems, the present device can adjust the seeding spacing, and the operation is as follows: Initially, the grooves 321 are all in an open state. When the user needs to adjust the first gear spacing, the movable frame 52 can be pushed to slide on the positioning rod 313. The movable frame 52 drives the movable plate 51 to slide inwardly toward the seeding frame 31. The movable plate 51 drives the first bump 511, the second bump 512, and the third bump 513 to slide synchronously. When the movable frame 52 slides to the first scale line 314 on the positioning rod 313, the first bump 511 contacts the movable rod 42, and the first bump 511 squeezes the movable rod 42, so that the movable rod 42 drives the fixed rod 41 to slide synchronously and squeeze the spring 33. The fixed rod 41 drives the rotating plate 43 to slide outwardly toward the groove 321. At this time, multiple rotating plates 43 can close the corresponding grooves 321, reducing the number of open grooves 321 and increasing the distance between the open grooves 321. Subsequently, the turntable 32 drives the grooves 321 to rotate, the grooves 321 drive the movable rod 42 to rotate, and the movable rod 42 drives the movable plate 51 to rotate synchronously through the chute. When the grooves 321 rotate to the material discharge port 312 for discharging operation, the adjustment of the first gear spacing can be achieved;

[0055] When the second gear spacing needs to be adjusted, the movable frame 52 is driven to slide on the positioning rod 313 to the second scale line 314 again. At this time, on the basis of the existing contact between the first bump 511 and the movable rod 42, the second bump 512 squeezes the movable rod 42 at the corresponding position again, so that the movable rod 42 repeats the above operation, reducing the number of grooves 321 again and increasing the distance between the open grooves 321 again;

[0056] When the user has completed seeding and does not need the seeds to be dropped for seeding operation, the movable frame 52 can be driven to slide to the third scale line 314 on the positioning rod 313, so that on the basis of the first bump 511 and the second bump 512, the third bump 513 squeezes the movable rod 42, so that the movable rod 42 drives the fixed rod 41 to move, and the fixed rod 41 drives the rotating plate 43 to move and closes all the grooves 321. Therefore, after seeding is completed, when the user pushes the fixed frame 11 to rotate, the seeds in the hopper 316 are blocked by the rotating plate 43, and the seeding operation can be stopped.

[0057] The present device realizes stepless adjustment of the first gear, second gear, and third gear planting spacings through the first, second, and third scale lines 314 of the movable frame 52 on the positioning rod 313, adapts to different wheat varieties and planting density requirements, can adapt to different soil conditions and climatic environments, and improves the flexibility of the equipment.

[0058] Such as Figure 5 and Figure 7As shown, a positioning rod 313 is slidably connected inside the moving frame 52. The positioning rod 313 is fixedly connected to the sowing frame 31. Scale lines 314 and positioning holes 315 are provided on the positioning rod 313. A screw rod 521 is threadedly connected inside the moving frame 52. The size of the screw rod 521 matches the size of the positioning hole 315.

[0059] Specifically, when the moving frame 52 moves to a suitable position on the positioning rod 313, rotate the screw rod 521 to enter the positioning hole 315, then the moving frame 52 can be fixed on the positioning rod 313, ensuring the stability of the spacing gear adjustment.

[0060] As Figure 6 and Figure 8 As shown, the inclined block 322 is fixedly connected to the inner lower surface of the groove 321. A discharge rack 325 is fixedly connected to the back surface of the rotating disc 32. The discharge rack 325 communicates with the inside of the groove 321.

[0061] As Figure 1 and Figure 6 As shown, a collection box 12 is fixedly connected to one side of the fixed frame 11. An inclined plate 15 is fixedly connected inside the collection box 12. The inclined plate 15 is rotatably connected to the inner wall of the rotating rod 21. One end of the inclined plate 15 is fixedly connected to the fixed frame 11.

[0062] Specifically, when sowing is completed and blanking is not required, there will be residual seeds in some of the grooves 321. When the wheel 22 drives the rotating rod 21 and the rotating disc 32 to rotate, the rotating disc 32 drives the groove 321 to rotate, and the groove 321 discharges the seeds through the blanking port 312, which will cause waste. And when it is necessary to close the groove 321 to adjust the planting spacing, the residual seeds in the groove 321 will hinder the movement of the rotating plate 43 and limit the rotating plate 43, making it difficult for the rotating plate 43 to completely close the groove 321, resulting in inaccurate adjustment of the planting spacing.

[0063] The seeds on the rotating plate 43 fall to the inner bottom of the groove 321, slide out of the groove 321 through the inclined block 322, and then fall onto the inclined plate 15 through the discharge rack 325, and the seeds on the rotating plate 43 fall to the inner bottom of the groove 321, slide out of the groove 321 through the inclined block 322, and then fall onto the inclined plate 15 from the drop hole 211, and the inclined plate 15 slides into the collecting box 12 for collection.

[0064] This device can automatically remove the residual seeds in the groove 321 when the movable plate 51 closes the groove 321, so as to prevent the residual seeds from obstructing the movement of the rotating plate 43, making it difficult for the rotating plate 43 to close the groove 321, and causing the problem of uneven sowing spacing. At the same time, the residual seeds are effectively collected in the collecting box 12 and can be reused for sowing, thereby reducing seed waste.

[0065] Working principle: when the device needs to be used for sowing, the seeds are poured into the hopper 316, the user holds the handle to push the fixed frame 11 to move, the fixed frame 11 drives the plow 13 to reclaim the dry land, then the fixed frame 11 drives the wheel 22 to rotate, the wheel 22 drives the rotating rod 21 to rotate, the rotating rod 21 drives the rotating disk 32 inside the sowing frame 31 to rotate synchronously, the rotating disk 32 drives the groove 321 to rotate, the groove 321 rotates to the feed port 311, the hopper 316 is opened, so that the seeds slide into the inside of the groove 321, the groove 321 continues to rotate and rotates to the discharge port 312, the seeds slide out of the groove 321 and slide into the soil through the discharge port 312, then the covering plate 14 pushes the soil to cover the seeds, and then repeats the above operation to complete the seed planting operation;

[0066] Initially, the grooves 321 are all in the open state. When the user needs to adjust the first gear spacing, the movable frame 52 can be pushed to slide on the positioning rod 313. The movable frame 52 drives the movable plate 51 to slide inward along the seeding frame 31. The movable plate 51 drives the first bump 511, the second bump 512, and the third bump 513 to slide synchronously. When the movable frame 52 slides to the first scale line 314 on the positioning rod 313, the first bump 511 comes into contact with the movable rod 42, and the first bump 511 squeezes the movable rod 42, causing the movable rod 42 to drive the fixed rod 41 to slide synchronously and compress the spring 33. The fixed rod 41 drives the rotating plate 43 to slide outward along the groove 321. At this time, multiple rotating plates 43 can close the corresponding grooves 321, reducing the number of open grooves 321 and increasing the distance between the open grooves 321. Subsequently, the rotating disk 32 drives the grooves 321 to rotate. The grooves 321 drive the movable rod 42 to rotate, and the movable rod 42 drives the movable plate 51 to rotate synchronously through the sliding groove. When the groove 321 rotates to the material discharge port 312 for discharging operation, the adjustment of the first gear spacing can be achieved;

[0067] When the second gear spacing needs to be adjusted, the movable frame 52 is driven to slide on the positioning rod 313 to the second scale line 314 again. At this time, on the basis of the existing contact between the first bump 511 and the movable rod 42, the second bump 512 squeezes the movable rod 42 at the corresponding position again, causing the movable rod 42 to repeat the above operation, further reducing the number of grooves 321 and increasing the distance between the open grooves 321 again;

[0068] When the user has completed seeding and no longer needs the seeds to fall for seeding operation, the movable frame 52 can be driven to slide to the third scale line 314 on the positioning rod 313. Based on the first bump 511 and the second bump 512, the third bump 513 squeezes the movable rod 42, causing the movable rod 42 to drive the fixed rod 41 to move. The fixed rod 41 drives the rotating plate 43 to move and closes all the grooves 321. Therefore, after seeding is completed, when the user pushes the fixed frame 11 to rotate, the seeds in the hopper 316 are blocked by the rotating plate 43, and the seeding operation can be stopped;

[0069] When the moving rod 42 drives the fixed rod 41 to move, and the fixed rod 41 drives the rotating plate 43 to move towards the outside of the groove 321, the spiral groove 421 on the surface of the moving rod 42 slides on the surface of the limiting rod 323. Limited by the limiting rod 323, the moving rod 42 rotates during the rising process. The moving rod 42 drives the first bevel gear 422 to rotate. The first bevel gear 422 meshes with the second bevel gear 432, so that the second bevel gear 432 drives the connecting rod 431 to rotate. The connecting rod 431 drives the rotating plate 43 to flip on the fixed rod 41. The seeds on the rotating plate 43 fall to the lower inner part of the groove 321, slide out of the groove 321 through the inclined block 322 and into the discharge rack 325, and then fall from the discharge rack 325 through the blanking hole 211 onto the inclined plate 15, and slide on the inclined plate 15 into the collection box 12 for collection operation;

[0070] When the moving frame 52 moves to a suitable position on the positioning rod 313, the rotating screw 521 enters the positioning hole 315, and the moving frame 52 can be fixed on the positioning rod 313, and the sowing operation can be completed.

[0071] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical idea of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
