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 symbol of the development of modern agricultural technology. The device sows seeds accurately into plug trays in an automated manner, achieving rapid and accurate seeding of a variety of crops such as vegetables, flowers, tobacco and medicinal materials.

[0003] In the existing fully automatic seeding device for breeding trays, during the process of discharging seeds into the breeding trays, the discharge port may be easily blocked 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 method of re-seeding is adopted, the seed sowing efficiency will be reduced, so it needs to be improved. Summary of the invention

[0035] The following is combined with Figure 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 an agricultural breeding disc includes a traveling frame 1, on which a lifting seat 2 and a driving unit 3 for driving the lifting seat 2 to rise and fall are provided. The driving unit 3 includes four hydraulic cylinders 31 installed on the traveling frame 1, and piston rods of the hydraulic cylinders 31 extend in a vertical direction and are connected to the lifting seat 2, so that the hydraulic cylinders 31 can drive the lifting seat 2 to rise and fall.

[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 a whole row of seeds.

[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, and 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 semi-cones 411 will fit together, so that the two semi-cones 411 together form a pointed cone; during the sowing process, the hydraulic cylinder 31 will drive the lifting seat 2 to descend, and the lifting seat 2 will drive the semi-cones 411 to descend through the elastic telescopic rod 412, so that the two semi-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 a guide surface 418, which is inclined; the upper end of the guide cylinder 42 is welded to the lifting seat 2, and the lower end of the guide cylinder 42 is provided with a chamfer. After the support plate 416 is supported on the ground, the hydraulic cylinder 31 will continue to drive the lifting seat 2 to descend, at which time the semi-cone 411 will be stationary, the elastic telescopic rod 412 will be gradually compressed, and the lifting seat 2 will drive the chamfer at the lower end of the guide cylinder 42 to press down the guide surface 418, so that the two semi-cones 411 are in a separated state, at which time there will be a gap 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 material guide cylinder 42 through the material guide pipe 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 sequence and fall into the gap between the two semi-cones 411, thereby realizing accurate sowing of the seeds; the two semi-cones 411 will be in a fitted state when inserted into the ground, and the two semi-cones 411 will be separated from each other only when the seeds are about to be sown, so that the soil is pushed to both sides by the two semi-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 cylinder 42 to rise and separate from the semi-cone 411, and the first spring 415 will return to a natural state, so that the two semi-cones 411 are fitted together; then the elastic telescopic rod 412 will gradually return to a 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 penetrated on the lifting seat 2 in the vertical direction. The positioning rods 21 correspond to the positioning grooves 417 one by one, and the positioning rods 21 are connected to the lifting seat 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 seat 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 a 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 prevent the two half cones 411 from clamping the seeds that have just been sown out of the soil.

[0047] Two magnetic plates 11 are welded on the walking frame 1. When the lifting seat 2 drives the soil-breaking cone 41 to rise and break away from the ground, the magnetic plate 11 will absorb the upper end of the positioning rod 21 upward, so that the positioning rod 21 rises and breaks away 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.

[0048] It is worth mentioning 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 cannot be further compressed. Therefore, the lifting seat 2 will drive the positioning rod 21 to descend and detach 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 connected to the traveling frame 1 by rotating around its own axis, 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 drop 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 process in the material guide barrel 42, the soft tube 522 is pulled by the material guide barrel 42 to be deformed, ensuring that the seeds in the material drop 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 arranged in an arc shape, and the height of the inner bottom wall of the storage box 51 gradually increases from the middle to the left and right sides thereof, 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 sowing is not needed.

[0052] like Figure 5 and Figure 6 As shown, a rotating shaft 53 is rotatably connected to the storage box 51, the rotating shaft 53 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, the rack 24 is vertically arranged, and 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, the rack 24 will drive the gear 533 to rotate, 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, the scraper 532 will rotate and 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 trough 511, and some of the pushed seeds will enter the feeding trough 511.

[0054] The side of the hard tube 521 is provided with a slot 523 connected to the inside of the hard tube 521, and the same material blocking plate 54 is inserted in all the slots 523. The material blocking plate 54 is connected to the material storage box 51 through the 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 material storage box 51. In the process of seeds entering the drop groove 511, the third spring 541 will be in a natural state, and the material blocking plate 54 will be inserted in the slot 523 and extend into the hard tube 521. At this time, the upper surface of the material blocking plate 54, the inner wall of the hard tube 521 and the groove wall of the drop groove 511 will jointly form a seed cavity, and only one seed can be placed in the seed cavity; that is, in the process of digging a pit with the soil breaking cone 41, the scraper 532 will push the seeds in the material storage box 51 to move, so that one seed is prepared in each seed cavity.

[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 . When the seeds in the material storage box 51 are lifted up by the scraper 532, the 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 the 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, the 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 part of the bottom wall of the material storage box 51 through the connecting rod 531. The scraper 532 will push the seeds in the material storage box 51 to slide down during the movement and reset process, so that the seeds pass over the feeding trough 511 again; that is, the scraper 532 can push the seeds to pass over the feeding trough 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 penetration rods 542, and the penetration rod 542 is penetrated in the material storage box 51 along its own axial sliding, 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, the extension plate 543 will drive the material blocking plate 54 to tilt down through the penetration 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 mesh 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 to the end of the storage box 51 where the feeding groove 511 is not provided, so that the seeds cannot continue to fall into the feeding 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 blocking plate 54 can be reinserted into the slot 523 and extend into the hard tube 521.

[0059] The implementation principle of the fully automatic sowing device for an agricultural breeding tray 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 digging at 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 twice from above the drop chute 511, 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 material 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 downward through the penetration 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 material 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 walking 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 the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
