Description

Technical Field

[0001] The present application relates to the technical field of agricultural sowing, and in particular to a fully automatic sowing device for agricultural breeding trays. Background Art

[0002] The fully automatic seeding device for seed trays, also known as the fully automatic plug tray seeder, is a significant development in modern agricultural technology. This device precisely sows seeds into plug trays through automation, enabling rapid and precise seeding of a variety of crops, including vegetables, flowers, tobacco, and medicinal herbs.

[0003] In the existing fully automatic seeding device for breeding trays, the discharge port is easily blocked during the process of discharging seeds into the breeding trays due to the certain viscosity of the soil. Even if it is not completely blocked, it may cause the seeds to not be discharged smoothly, resulting in uneven sowing and affecting the planting effect. If the re-seeding method is adopted, the seed sowing efficiency will be reduced, so it needs to be improved. Summary of the Invention

[0004] In order to ensure the planting effect of seeds and improve the sowing efficiency of seeds, the present application provides a fully automatic sowing device for agricultural breeding trays.

[0005] The present application provides a fully automatic seeding device for an agricultural breeding tray, which adopts the following technical solution: a fully automatic seeding device for an agricultural breeding tray, comprising a traveling frame, a lifting seat and a driving unit for driving the lifting seat to move up and down, the lifting seat being provided with a plurality of seeding units arranged in sequence along a horizontal direction, and the traveling direction of the traveling frame being perpendicular to the arrangement direction of the seeding units;

[0006] The sowing unit includes a soil-breaking cone and a material guide cylinder. The soil-breaking cone includes two semi-cones and two elastic telescopic rods. The elastic telescopic rods are arranged vertically. The upper ends of the elastic telescopic rods are connected to the lifting seat. The lower ends of the elastic telescopic rods are provided with dovetail blocks that slide horizontally and fit into the semi-cones. The dovetail blocks are connected to the semi-cones by first springs, and the tips of the semi-cones face downward. When the first spring is in a natural state, the tips of the two semi-cones will fit together.

[0007] The top of the semi-cone is provided with a support plate for supporting it on the ground, and the upper surface of the support plate is provided with a positioning groove. A plurality of positioning rods are slidably engaged with the lifting seat in the vertical direction. The positioning rods correspond to the positioning grooves one by one, and the positioning rods are connected to the lifting seat via a second spring. When the second spring is in the natural state, the positioning rods will be inserted into the positioning grooves, and the two semi-cones will be in a separated state.

[0008] The traveling frame is provided with a magnetic plate for adsorbing and fixing the positioning rod. When the lifting seat drives the earth-breaking cone to rise and leave the ground, the magnetic plate will adsorb the positioning rod upward, so that the positioning rod will be separated from the positioning groove.

[0009] The upper end of the material guide cylinder is arranged on the lifting seat and is connected to a deformable material guide tube. The lower end of the semi-cone is provided with a guide surface for pressing the lower end of the material guide cylinder downward, and the guide surface is arranged at an angle; after the support plate is supported on the ground, the lifting seat will drive the lower end of the material guide cylinder to press the guide surface downward, so that the two semi-cones are in a separated state.

[0010] Optionally, a storage unit is also included, which includes a storage box arranged on a walking frame, and a plurality of material drop troughs are provided at the bottom of the storage box. The arrangement direction of the material drop troughs is the same as the arrangement direction of the sowing unit, and the material drop troughs correspond to the material guide pipes one by one and are connected to each other.

[0011] Optionally, the inner bottom wall of the material storage box is arranged in an arc shape, and the height of the inner bottom wall of the material storage box gradually increases from the middle to the left and right sides thereof, and the material drop chute is not located in the middle of the inner bottom wall of the material storage box;

[0012] The material storage box is rotatably connected with a rotating shaft, the rotating shaft is connected with a scraper through a connecting rod, and the scraper can be rotatably abutted against the inner bottom wall of the material storage box.

[0013] Optionally, the lifting seat is connected to a rack via a first connecting frame, and the rack is vertically arranged; a gear is coaxially connected to the rotating shaft, and the gear is located on the lifting track of the rack;

[0014] Before the two half cones are in a separated state, the lifting seat will drive the rack to engage with the gear and then disengage from the gear through the first connecting frame. During the rotation process, the gear will push the seeds in the storage box into the drop chute.

[0015] Optionally, the material guide pipe includes a hard pipe and a soft pipe, the upper end of the hard pipe is connected to the material chute, the lower end of the hard pipe is connected to the upper end of the soft pipe, and the lower end of the soft pipe is connected to the upper end of the material guide cylinder;

[0016] The side of the hard tube is provided with a slot connected to the inside of the hard tube, and the same material blocking plate is inserted into all the slots; when the material blocking plate is inserted into the slot and extends into the hard tube, the upper surface of the material blocking plate, the inner wall of the hard tube and the groove wall of the material drop trough will jointly form a seed cavity, and only one seed can be placed in the seed cavity.

[0017] Optionally, the material blocking plate is slidably fitted in the material storage box, the projection of the movement trajectory of the material blocking plate on the vertical plane is inclined, and the material blocking plate is connected to the material storage box through a third spring, and when the third spring is in a natural state, the material blocking plate will be inserted into the slot and extend into the hard tube;

[0018] The lifting seat is connected to a pressure plate through a second connecting frame. An extension plate is provided on the material blocking plate, and the extension plate is located on the movement trajectory of the pressure plate. After the two semi-cones are in a separated state, the pressure plate will press down the extension plate, so that the material blocking plate slides out of the hard tube.

[0019] Optionally, the rotating shaft and the material storage box are connected to the same vortex spring. When the vortex spring is in a natural state, the scraper will contact the middle of the bottom wall of the material storage box.

[0020] Optionally, the traveling frame is provided with a pressure roller located behind the sowing unit, the pressure roller is horizontally arranged and rotates around its own axis to be connected to the traveling frame, and the lowest point of the pressure roller is on the same horizontal plane as the lowest point of the traveling frame.

[0021] In summary, this application has the following beneficial technical effects:

[0022] 1. The user can achieve precise sowing of the entire row of seeds by pushing the traveling frame and controlling the hydraulic cylinder, thereby ensuring the planting effect of the seeds and improving the sowing efficiency;

[0023] 2. The two half cones will be in a close fit when inserted into the ground. They will separate when the seeds are about to be sown, so that the soil is pushed to the sides by the two half cones. Therefore, the soil will not affect the sowing of the seeds, thereby ensuring the planting effect of the seeds and improving the sowing efficiency of the seeds.

[0024] 3. After the two half cones are in the separated state, the positioning rod will be inserted into the positioning groove, so that the two half cones are inserted and fixed. Therefore, the two half cones will not fit together before rising out of the soil, so as to prevent the two half cones from clamping the seeds that have just been planted from the soil;

[0025] 4. When the lifting seat drives the soil-breaking cone to rise and break away from the ground, the magnetic plate will attract the upper end of the positioning rod upward, causing the positioning rod to rise and break away from the positioning slot. At this time, the first spring will return to its natural state, allowing the two half cones to fit together, so that the soil-breaking cone can continue to dig holes for sowing in the subsequent process;

[0026] 5. After the seeds are sown, the pressing roller will roll and push the soil dug out by the soil-breaking cone during the movement of the walking frame, so that this part of the soil is pushed into the pit and flattened, thus completing a series of sowing operations.

DETAILED DESCRIPTION

[0035] The following is combined with Figures 1-7 This application is described in further detail.

[0036] The present application discloses a fully automatic seeding device for agricultural breeding trays. Figure 1 and Figure 2 As shown, a fully automatic sowing device for agricultural breeding trays includes a traveling frame 1, on which is provided a lifting seat 2 and a driving unit 3 for driving the lifting seat 2 to move up and down. The driving unit 3 includes four hydraulic cylinders 31 installed on the traveling frame 1, and the piston rods of the hydraulic cylinders 31 extend in the vertical direction and are connected to the lifting seat 2, so that the hydraulic cylinders 31 can drive the lifting seat 2 to move up and down.

[0037] The lifting seat 2 is provided with a plurality of sowing units 4 arranged in sequence along the horizontal direction. The moving direction of the traveling frame 1 is perpendicular to the arrangement direction of the sowing units 4, that is, during the movement of the traveling frame 1, the sowing units 4 will sow the seeds in the entire row.

[0038] like Figure 2 and Figure 3As shown, the sowing unit 4 includes a soil-breaking cone 41 and a material guide cylinder 42. The soil-breaking cone 41 includes two semi-cones 411 and two elastic telescopic rods 412. The elastic telescopic rods 412 are vertically arranged, and the upper ends of the elastic telescopic rods 412 are welded to the lower surface of the lifting seat 2. The lower ends of the elastic telescopic rods 412 are welded with dovetail blocks 413; the upper surface of the semi-cone 411 is provided with a dovetail groove 414 extending in the horizontal direction, and the dovetail block 413 is slidably embedded in the dovetail groove 414, and the dovetail block 413 is connected to the semi-cone 411 through a first spring 415, and the tip of the semi-cone 411 faces downward, one end of the first spring 415 is fixedly connected to the dovetail block 413, and the other end of the first spring 415 is fixedly connected to the groove wall of the dovetail groove 414.

[0039] Before sowing, the first spring 415 will be in a natural state, and the tips of the two half cones 411 will fit together, so that the two half cones 411 together form a pointed cone; during the sowing process, the hydraulic cylinder 31 will drive the lifting base 2 to descend, and the lifting base 2 will drive the half cones 411 to descend through the elastic telescopic rod 412, so that the two half cones 411 together penetrate into the soil, thereby realizing the digging of sowing holes.

[0040] A support plate 416 is welded to the top of the half cone 411. When the two half cones 411 penetrate into the soil to a specified depth, the lower surface of the support plate 416 will be supported on the ground, so that the half cone 411 cannot continue to penetrate into the soil, ensuring that the earth-breaking cone 41 can only dig a pit of a specified depth each time.

[0041] The lower end of the semi-cone 411 is provided with an inclined guide surface 418. The upper end of the guide cylinder 42 is welded to the lifting base 2, and the lower end of the guide cylinder 42 is chamfered. After the support plate 416 is supported on the ground, the hydraulic cylinder 31 will continue to drive the lifting base 2 downward. At this time, the semi-cone 411 will be stationary, the elastic telescopic rod 412 will gradually compress, and the lifting base 2 will drive the chamfered lower end of the guide cylinder 42 to press down on the guide surface 418, causing the two semi-cones 411 to separate. At this time, a gap will exist between the two semi-cones 411, and the first spring 415 will be in a compressed state.

[0042] like Figure 4 and Figure 5 As shown, a storage unit 5 is provided on the traveling frame 1, and the storage unit 5 includes a storage box 51 installed on the top of the traveling frame 1, and seeds can be stored in the storage box 51; the top of the storage box 51 is open, and a plurality of feeding troughs 511 are provided at the bottom of the storage box 51, and the arrangement direction of the feeding troughs 511 is the same as the arrangement direction of the sowing unit 4, and the feeding troughs 511 are connected to the guide cylinder 42 through the guide tube 52.

[0043] The seeds in the storage box 51 can pass through the feeding trough 511, the guiding tube 52 and the guiding cylinder 42 in turn and fall into the gap between the two half cones 411, thereby realizing accurate sowing of the seeds; the two half cones 411 will be in a fitted state when inserted into the ground, and the two half cones 411 will only separate from each other when the seeds are about to be sown, so that the soil is pushed to both sides by the two half cones 411, so the soil will not affect the sowing of the seeds, thereby ensuring the planting effect of the seeds and improving the sowing efficiency of the seeds.

[0044] Afterwards, the hydraulic cylinder 31 will drive the lifting seat 2 to rise, and the lifting seat 2 will first drive the material guide barrel 42 to rise and separate from the semi-cone 411, and the first spring 415 will return to its natural state, so that the two semi-cones 411 will fit together; then the elastic telescopic rod 412 will gradually return to its natural state, and the semi-cone 411 will return to its original position as the elastic telescopic rod 412 rises.

[0045] like Figure 2 and Figure 3 As shown, a positioning groove 417 is provided on the upper surface of the support plate 416, and a plurality of positioning rods 21 are slidably provided on the lifting base 2 in the vertical direction. The positioning rods 21 correspond one-to-one to the positioning grooves 417, and the positioning rods 21 are connected to the lifting base 2 through the second spring 22. One end of the second spring 22 is fixedly connected to the positioning rod 21, and the other end of the second spring 22 is fixedly connected to the lifting base 2.

[0046] Before the two half cones 411 are separated, the second spring 22 will be in a compressed state, and the positioning rod 21 will be pressed against the upper surface of the support plate 416; after the two half cones 411 are in a separated state, the positioning groove 417 will move to just below the positioning rod 21, the second spring 22 will return to its natural state, and the positioning rod 21 will be inserted into the positioning groove 417, so that the two half cones 411 are inserted and fixed, so the two half cones 411 will not fit together before rising out of the soil, so as to avoid the two half cones 411 clamping the seeds that have just been sown out of the soil.

[0047] Two magnetic plates 11 are welded to the walking frame 1. When the lifting seat 2 drives the breaking cone 41 to rise and separate from the ground, the magnetic plate 11 will adsorb the upper end of the positioning rod 21 upward, causing the positioning rod 21 to rise and separate from the positioning groove 417. At this time, the first spring 415 will return to its natural state, causing the two half cones 411 to fit together, so that the breaking cone 41 can continue to dig holes for sowing in the subsequent process.

[0048] It is worth noting that after the earth-breaking cone 41 penetrates into the soil, the second spring 22 will be compressed to the shortest state, so that the second spring 22 can no longer be compressed. Therefore, the lifting seat 2 will drive the positioning rod 21 to descend and separate from the magnetic plate 11 through the second spring 22, so that the positioning rod 21 can plug and fix the separated half-cone 411 in the subsequent process.

[0049] like Figure 1 and Figure 2 As shown, the traveling frame 1 is provided with a pressure roller 12 located behind the sowing unit 4. The pressure roller 12 is horizontally arranged and rotates around its own axis to be connected to the traveling frame 1. The lowest point of the pressure roller 12 is on the same horizontal plane as the lowest point of the traveling frame 1. That is, after the seed sowing is completed, the pressure roller 12 will roll and push the soil dug out by the soil-breaking cone 41 during the movement of the traveling frame 1, so that this part of the soil is pushed into the pit and flattened, thereby completing a series of sowing operations.

[0050] like Figure 4 and Figure 5 As shown, the material guide tube 52 includes a hard tube 521 and a soft tube 522. The upper end of the hard tube 521 is fixedly connected to the material chute 511, the lower end of the hard tube 521 is fixedly connected to the upper end of the soft tube 522, and the lower end of the soft tube 522 is fixedly connected to the upper end of the material guide barrel 42. During the lifting and lowering process within the material guide barrel 42, the soft tube 522 is pulled by the material guide barrel 42 and deformed, ensuring that the seeds in the material chute 511 can pass through the hard tube 521 and the soft tube 522 in sequence and fall into the material guide barrel 42.

[0051] The inner bottom wall of the storage box 51 is arc-shaped, and the height of the inner bottom wall of the storage box 51 gradually increases from the middle to the left and right sides, so that the seeds in the storage box 51 are concentrated in the middle of the inner bottom wall of the storage box 51, and the feeding trough 511 is not in the middle of the inner bottom wall of the storage box 51, so the seeds cannot enter the feeding trough 511 without being pushed, thereby preventing the seeds from falling at will when they are not needed for sowing.

[0052] like Figure 5 and Figure 6 As shown, the storage box 51 is rotatably connected to a rotating shaft 53, which is horizontally arranged. The rotating shaft 53 is connected to the same scraper 532 through two connecting rods 531, and a gear 533 is coaxially connected to the rotating shaft 53; the upper surface of the lifting seat 2 is connected to the rack 24 through the first connecting frame 23, and the rack 24 is vertically arranged. The gear 533 is located on the lifting trajectory of the rack 24.

[0053] When the soil-breaking cone 41 penetrates into the soil, the lifting seat 2 will drive the rack 24 to descend through the first connecting frame 23, and the rack 24 will drive the gear 533 to rotate, and the gear 533 will drive the rotating shaft 53 to rotate. The rotating shaft 53 will drive the scraper 532 to rotate through the connecting rod 531, and the scraper 532 will rotate to contact the inner bottom wall of the storage box 51, so that the seeds in the storage box 51 are pushed up and pass over the feeding chute 511, and some of the pushed seeds will enter the feeding chute 511.

[0054] The side of the rigid tube 521 is provided with a slot 523 connected to the interior of the rigid tube 521. The same material blocking plate 54 is inserted into all the slots 523. The material blocking plate 54 is connected to the storage box 51 via a third spring 541. One end of the third spring 541 is fixedly connected to the material blocking plate 54, and the other end of the third spring 541 is fixedly connected to the storage box 51. When the seeds enter the chute 511, the third spring 541 will be in a natural state, and the material blocking plate 54 will be inserted into the slot 523 and extend into the rigid tube 521. At this time, the upper surface of the material blocking plate 54, the inner wall of the rigid tube 521, and the trough wall of the chute 511 will jointly form a seed cavity, in which only one seed can be placed. That is, when the soil-breaking cone 41 is digging a hole, the scraper 532 will push the seeds in the storage box 51 to move, so that each seed cavity is stocked with one seed.

[0055] The rotating shaft 53 and the material storage box 51 are commonly connected to a same vortex spring 534 , one end of the vortex spring 534 is fixedly connected to the rotating shaft 53 , and the other end of the vortex spring 534 is fixedly connected to the material storage box 51 . In the process of scraper 532 pushing the seeds in storage box 51 to rise, vortex spring 534 will be in a deformed state, and some of the pushed seeds will jump over the scraper 532, so that there are seeds on both sides of scraper 532; after the seeds are prepared in the seed cavity, the lifting seat 2 will drive the rack 24 to descend and disengage from the gear 533 through the first connecting frame 23. At this time, vortex spring 534 will return to its natural state, so that the rotating shaft 53 rotates and resets, and the rotating shaft 53 will drive the scraper 532 to rotate and reset to the middle of the bottom wall of the storage box 51 through the connecting rod 531. The scraper 532 will push the seeds in the storage box 51 to slide down during the movement and reset process, so that the seeds pass over the feeding chute 511 again; that is, the scraper 532 can push the seeds to pass over the feeding chute 511 twice, ensuring that one seed can be prepared in each seed cavity.

[0056] like Figure 6 and Figure 7 As shown, the material blocking plate 54 is connected to the extension plate 543 through two penetrating rods 542. The penetrating rods 542 are slidably penetrated in the material storage box 51 along their own axial direction, so that the material blocking plate 54 can be slidably fitted in the material storage box 51, and the projection of the movement trajectory of the material blocking plate 54 on the vertical plane is inclined; the upper surface of the lifting seat 2 is connected to the pressing plate 26 through the second connecting frame 25, and the extension plate 543 is located on the movement trajectory of the pressing plate 26.

[0057] After the two half cones 411 are in a separated state, the pressure plate 26 will press down the extension plate 543, the third spring 541 will be deformed, and the extension plate 543 will drive the material blocking plate 54 to tilt down through the penetrating rod 542. The material blocking plate 54 will slide out of the hard tube 521, and the seeds in the seed cavity will pass through the hard tube 521, the hose 522 and the material guide barrel 42 in turn and fall into the gap between the two half cones 411, thereby realizing automatic sowing of seeds.

[0058] When the hydraulic cylinder 31 drives the lifting seat 2 to rise, the rack 24 will first engage with the gear 533 and then disengage from the gear 533. The gear 533 will drive the scraper 532 through the rotating shaft 53 and the connecting rod 531 to push the seeds toward the end of the storage box 51 where the drop groove 511 is not provided, so that the seeds cannot continue to fall into the drop groove 511; and the pressure plate 26 will rise and disengage from the extension plate 543, and the third spring 541 will return to its natural state, so that the material blocking plate 54 will be reinserted into the slot 523 and extend into the hard tube 521.

[0059] The implementation principle of the fully automatic sowing device for agricultural breeding trays in the embodiment of the present application is as follows: during the seed sowing process, the user will push the walking frame 1 to the place to be sown, and then the walking frame 1 will temporarily stop moving, the hydraulic cylinder 31 will drive the lifting seat 2 to descend, and the lifting seat 2 will drive the semi-cone 411 to descend through the elastic telescopic rod 412, so that the two semi-cones 411 will penetrate into the soil together, and the support plate 416 will be supported on the ground, so that the semi-cone 411 cannot continue to penetrate into the soil, thereby achieving a pit of a specified depth; at the same time, the lifting seat 2 will drive the rack 24 to descend through the first connecting frame 23, and the rack 24 will first engage with the gear 533 and then disengage from the gear 533, so that the scraper 532 can push the seeds in the storage box 51 to pass over the drop chute 511 twice, ensuring that one seed can be prepared in each seed cavity.

[0060] Afterwards, the elastic telescopic rod 412 will be gradually compressed, and the chamfer at the lower end of the guide cylinder 42 will press down the guide surface 418, so that the two half cones 411 are in a separated state, and the two half cones 411 will push the soil in the ground to both sides. At this time, there will be a gap between the two half cones 411, and the positioning rod 21 will be inserted into the positioning groove 417, so that the half cones 411 are inserted and fixed; the pressing plate 26 will press down the extension plate 543, and the extension plate 543 will drive the material blocking plate 54 to tilt down through the through rod 542, and the material blocking plate 54 will slide out of the hard tube 521. The seeds in the seed cavity will pass through the hard tube 521, the hose 522 and the guide cylinder 42 in turn and fall into the gap between the two half cones 411, thereby realizing automatic sowing of seeds.

[0061] Then the hydraulic cylinder 31 will drive the lifting seat 2 to rise and reset, and the lifting seat 2 will drive the material guide cylinder 42 and the soil-breaking cone 41 to rise and reset, and the magnetic plate 11 will adsorb and fix the upper end of the positioning rod 21, so that the positioning rod 21 rises and disengages from the positioning groove 417. At this time, the first spring 415 will return to its natural state, so that the two half cones 411 fit together, so that the soil-breaking cone 41 can continue to dig holes for sowing in the subsequent process.

[0062] Finally, the user will continue to push the walking frame 1 forward, and the pressing roller 12 will roll on the ground to push the soil dug out by the soil-breaking cone 41, so that this part of the soil is pushed into the pit and flattened, thereby completing a series of sowing operations.

[0063] In summary, the user can achieve accurate sowing of a whole row of seeds by pushing the traveling frame 1 forward and controlling the hydraulic cylinder 31, thereby ensuring the planting effect of the seeds and improving the seed sowing efficiency.

[0064] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
