A wheat seeding and fertilizing integrated machine

Abstract

The present invention discloses a wheat seeding and fertilizing integrated machine, which relates to the technical field of agricultural machinery. A wheat seeding and fertilizing integrated machine includes a walking vehicle, on which a material box is fixedly connected. In the middle of the material box, a partition board is fixedly connected. At the bottom end of the material box, two rows of equally spaced blanking pipes are communicated. It also includes an installation sleeve, which is fixedly connected to the inner top end of the blanking pipe. This device has two modes: hill-drop seeding and drill seeding. In the hill-drop seeding mode, the hydraulic rod continuously expands and contracts to drive the plug board to intermittently move downward to make holes in the field soil, while the first motor drives the blanking ball to continuously rotate counterclockwise, and then continuously pour a certain amount of fertilizer or seeds downward for intermittent blanking. In the drill seeding mode, after the hydraulic rod extends, it remains stationary. The plug board is inserted into the soil and moves backward with this device to open a groove in the field soil. When the first motor drives the blanking ball to rotate clockwise for a certain distance, the opening and closing block is controlled to open, and the fertilizer or seeds can directly pass through the blanking ball for continuous blanking.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly to a wheat seeding and fertilizing integrated machine. Background Art

[0002] In modern agricultural production, wheat seeding and fertilizing integrated machines are widely used due to their high efficiency and convenience. Such machines usually integrate seeding and fertilizing functions, and can complete seeding and fertilizing simultaneously in one operation, improving agricultural production efficiency.

[0003] However, the existing wheat seeding and fertilizing integrated machines have certain limitations in function. Most of the existing machines can only execute a single seeding mode and cannot flexibly adjust the seeding method according to different agronomic requirements. The most common one is strip seeding (strip seeding means evenly scattering seeds on the field to form a continuous strip distribution). This seeding method is suitable for large-scale conventional agricultural production. However, in special situations such as agricultural experiments, in order to ensure the utilization rate of seeds and the growth space of plants, a more precise seeding method is required, such as hill seeding (hill seeding means concentrating seeds at predetermined points, and only a certain number of seeds are sown at each point). This method can better control the distribution density of seeds, improve the germination rate of seeds and the growth quality of plants. And in actual agricultural production, the soil conditions, climate environments and crop varieties of different plots may vary. Therefore, different seeding and fertilizing strategies are needed. For example, some plots may be more suitable for strip seeding, while others are more suitable for hill seeding. In wet soil, the seeding depth can be appropriately reduced to avoid root rot during germination. In relatively dry sandy soil, the seeding depth can be increased to ensure that the seeds can contact sufficient moisture. However, the existing machines cannot quickly switch between these different requirements, which limits their application scope and operation efficiency.

[0004] To solve the above problems, we propose a wheat seeding and fertilizing integrated machine. This seeding and fertilizing integrated machine can not only switch the seeding method (strip seeding or hill seeding) according to actual usage requirements, but also adjust the fertilizing and seeding depth to meet different agronomic requirements. Summary of the Invention

[0005] To overcome the drawback that the existing wheat seeding and fertilizing integrated machines can only execute a single seeding method and cannot flexibly adjust the seeding method according to different agronomic requirements, the present invention provides a wheat seeding and fertilizing integrated machine. This seeding and fertilizing integrated machine can not only switch the seeding method (strip seeding or hill seeding) according to actual usage requirements, but also adjust the fertilizing and seeding depth to meet different agronomic requirements.

[0006] The technical solution is as follows: A wheat seeding and fertilizing integrated machine includes a walking vehicle. A material box is fixedly connected to the walking vehicle. A partition is fixedly connected to the middle of the material box. Two rows of equidistantly distributed blanking pipes are communicated with the bottom end of the material box. It also includes an installation sleeve. The installation sleeve is fixedly connected to the inner top end of the blanking pipe. A blanking ball is rotatably connected in the installation sleeve. Connecting rods are fixedly connected between two laterally adjacent blanking balls. Two identical connecting rods are rotatably connected to the bottom end of the material box. This connecting rod is fixedly connected to the adjacent blanking ball. A pressing block is slidably connected to the bottom end of the installation sleeve. A first spring is connected between the pressing block and the installation sleeve. A switching block is rotatably connected to the bottom end of the blanking ball. A contact block is fixedly connected to the side of the switching block close to the pressing block. The pressing block is a wedge-shaped structure with a flat upper part and an inclined lower part. The blanking ball and the contact block are both in pressing cooperation with the pressing block. Two laterally symmetrical first torsion springs are connected between the switching block and the blanking ball. A first motor is fixedly connected to the material box. The output shaft of the first motor is fixedly connected to an adjacent connecting rod. A pulley group is connected between the two connecting rods rotatably connected to the material box. A grooving component for grooving the field soil for fertilizing and seeding is provided on the blanking pipe and the material box. A soil covering component for separately covering the fertilizer and seeds with soil is provided on the material box.

[0007] As an improvement of the above solution, the grooving component includes equidistantly distributed sliding cylinders. The equidistantly distributed sliding cylinders are slidably connected to the blanking pipe on the side close to the walking vehicle. A connecting plate is fixedly connected between two adjacent sliding cylinders. A hydraulic rod is fixedly connected to the material box. The telescopic end of the hydraulic rod is fixedly connected to a fixing plate. The fixing plate is fixedly connected to the adjacent sliding cylinder. A fixedly connected frame is fixedly connected to the bottom end of the sliding cylinder. The fixedly connected frame is rotatably connected with an inserting plate. A contact rod is fixedly connected to the rotatable connection of the inserting plate and the fixedly connected frame. A second torsion spring is connected between the inserting plate and the fixedly connected frame. Guide blocks are fixedly connected to the sliding cylinder in a circumferentially equidistant manner. A sliding rod is slidably connected in the guide block. A pressing ring is fixedly connected between the bottom ends of the sliding rods. The pressing ring is in pressing cooperation with the contact rod. A limiting ring is fixedly connected between the top ends of the sliding rods. A second spring is connected between the sliding rod and the adjacent guide block. The elastic force of the second spring is greater than that of the second torsion spring. Equidistantly distributed internal thread cylinders are rotatably connected to the bottom end of the material box. An external thread cylinder is connected to the internal thread cylinder through threads. The external thread cylinder is sleeved outside the limiting ring. The limiting ring moves down to contact the external thread cylinder sleeve. Three groups of equidistantly distributed guide rods are fixedly connected to the bottom end of the material box. Each group of guide rods is slidably connected to the adjacent external thread cylinder.

[0008] As an improvement of the above solution, adjacent inserting plates are mutually attached to form a cone and close the inside of the sliding cylinder.

[0009] As an improvement to the above solution, the soil covering component includes a first mounting plate fixedly connected to the bottom end of the material box. The bottom end of the first mounting plate is fixedly connected with evenly distributed first soil covering plates. The bottom end of the material box is fixedly connected with a second mounting plate. A sliding plate is slidably connected to the second mounting plate. The bottom end of the sliding plate is fixedly connected with evenly distributed second soil covering plates. A threaded rod is rotatably connected to the second mounting plate. The threaded rod is threadedly connected to the sliding plate. A rotating frame is rotatably connected to the sliding plate. The bottom end of the rotating frame is rotatably connected with a soil pressing roller. A horizontally symmetric third torsion spring is connected between the rotating frame and the sliding plate.

[0010] As an improvement to the above solution, the first soil covering plate and the second soil covering plate are inclined in opposite directions and are respectively used to push the soil on both sides of the sowing groove.

[0011] As an improvement to the above solution, it further includes a synchronization component for synchronously adjusting the height of the internally threaded cylinder. The synchronization component includes a worm gear fixedly connected to the bottom end of the internally threaded cylinder. A second motor is fixedly connected to the material box. A rotating shaft is fixedly connected to the output shaft of the second motor. Evenly distributed worm shafts are fixedly connected to the rotating shaft. The worm shafts are engaged with adjacent worm gears.

[0012] As an improvement to the above solution, it further includes a blowing component for ensuring the fluidity of seeds. The blowing component includes a cover plate rotatably connected to the top end of the material box. A blower is communicated with the material box. A ventilation opening with an intercepting net is provided on the material box.

[0013] Beneficial effects: 1. The device has two modes: hill-drop seeding and drill seeding. In the hill-drop seeding mode, the hydraulic rod continuously expands and contracts, thereby driving the insertion plate to intermittently move downward to make holes in the farmland soil. The first motor drives the blanking ball to continuously rotate counterclockwise, and a certain amount of fertilizer or seeds can be continuously filled and poured downward for intermittent blanking. In the drill seeding mode, after the hydraulic rod extends, it remains stationary. The insertion plate is inserted into the soil and moves backward with the device, and a strip-shaped groove can be opened in the farmland soil. The first motor drives the blanking ball to rotate clockwise by a certain distance, and the opening and closing block can be opened downward, and the fertilizer or seeds can directly penetrate the blanking ball for continuous blanking. The seeding method can be switched according to actual use requirements to meet different agronomic requirements.

[0014] 2. The first soil covering plate and the second soil covering plate follow behind the fertilizer and seeds respectively. After fertilization, the first soil covering plate will push the soil on the left side of the hole or groove to cover the fertilizer first, avoiding the phenomenon of burning seedlings caused by the direct contact between the seeds and the fertilizer behind. After sowing, the second soil covering plate will push the soil on the right side of the hole or groove to cover the seeds. The rotation of the threaded rod can adjust the soil filling amount of the second soil covering plate, thereby adjusting the burial depth of the seeds. The rotation of the internally threaded cylinder can adjust the height of the externally threaded cylinder, thereby adjusting the depth of the fertilizer entering the soil.

Detailed implementation manners

[0029] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0030] Embodiment 1: A wheat seeding and fertilizing integrated machine, as Figures 1-8As shown in the figure, it includes a walking vehicle 1, a material box 2, a partition board 3, a blanking pipe 4, a connecting rod 5, a mounting sleeve 6, a blanking ball 7, an extrusion block 8, a first spring 9, an opening and closing block 10, a contact block 11, a first torsion spring 12, a first motor 13, a pulley group 131, a grooving assembly and a soil covering assembly. The front part of the walking vehicle 1 is fixedly connected with the material box 2. In the middle of the material box 2, a partition board 3 is fixedly connected. Three equally spaced blanking pipes 4 are communicated with both the front and rear parts on the lower side of the material box 2. An upper part of the blanking pipe 4 is fixedly connected with a mounting sleeve 6. A blanking ball 7 is rotatably connected in the mounting sleeve 6. Connecting rods 5 are fixedly connected between two adjacent blanking balls 7 on the left and right. Two identical connecting rods 5 are rotatably connected to the right part of the lower side of the material box 2, and are fixedly connected to the blanking ball 7 adjacent to the left end of this connecting rod 5. A lower part of the mounting sleeve 6 is slidably connected with an extrusion block 8. A first spring 9 is connected between the extrusion block 8 and the mounting sleeve 6. An opening and closing block 10 is rotatably connected to the lower side of the blanking ball 7. A contact block 11 is fixedly connected to one side of the opening and closing block 10 close to the extrusion block 8. The extrusion block 8 is a wedge-shaped structure with a flat upper part and an inclined lower part. The blanking ball 7 and the contact block 11 are both rotationally and extrusionally matched with the extrusion block 8. Two horizontally symmetric first torsion springs 12 are connected between the opening and closing block 10 and the blanking ball 7. A first motor 13 is fixedly connected to the lower right side of the material box 2. The output shaft of the first motor 13 is fixedly connected with an adjacent connecting rod 5. A pulley group 131 is connected between the front and rear two connecting rods 5 rotatably connected to the lower side of the material box 2. A grooving assembly for grooving the field soil for fertilizing and sowing is provided on the blanking pipe 4 and the material box 2. A soil covering assembly for respectively covering soil on the fertilizer and seeds is provided on the material box 2.

[0031] When using this device, the partition plate 3 divides the hopper 2 into two front and rear spaces. The staff puts fertilizers into the rear space of the hopper 2, and wheat seeds are placed in the rear space. In the initial state, the opening of the feeding ball 7 faces upward, and the opening and closing block 10 blocks the lower side of the feeding ball 7. The fertilizers and seeds in the hopper 2 will enter the feeding pipe 4, thus filling the feeding ball 7. Then, the staff drives the walking vehicle 1 to move backward. When the walking vehicle 1 moves backward, it drives this device to move backward. When this device moves backward, the grooving assembly will be inserted into the soil downward according to the sowing method to create holes or grooves. During the movement of this device, the staff controls the operation of the first motor 13. If hole sowing is required, the output shaft of the first motor 13 is continuously rotated counterclockwise. The counterclockwise rotation of the output shaft of the first motor 13 drives the feeding ball 7 to continuously rotate counterclockwise through the connecting rod 5. When the feeding ball 7 rotates counterclockwise, under the action of the expansion and contraction of the first spring 9, the feeding ball 7 will continuously push the extrusion block 8 to retract into the mounting sleeve 6. The continuous counterclockwise rotation of the feeding ball 7 continuously holds a certain amount of fertilizers or seeds and pours them downward, so that the fertilizers or seeds fall into the holes created by the grooving assembly through the feeding pipe 4. If strip sowing is required, the output shaft of the first motor 13 is rotated clockwise for a certain stroke. The clockwise rotation of the output shaft of the first motor 13 drives the feeding ball 7 to rotate clockwise through the connecting rod 5. The clockwise rotation of the feeding ball 7 drives the opening and closing block 10 and the contact block 11 to rotate clockwise. When the contact block 11 rotates clockwise, it will be squeezed by the extrusion block 8 and swing upward. The upward swing of the contact block 11 drives the opening and closing block 10 to swing downward to open, and the first torsion spring 12 deforms. After the opening and closing block 10 swings downward to open, the fertilizers or seeds can directly penetrate the feeding ball 7, so that the feeding pipe 4 continuously feeds materials. By controlling the clockwise or counterclockwise rotation of the output shaft of the first motor 13, the feeding methods of fertilizers and seeds can be switched to adapt to different planting methods. Under the action of the moving direction of this device, the fertilizers will enter the holes earlier than the seeds, and the soil covering assembly can perform soil covering twice to cover the soil for fertilizers and seeds respectively, avoiding the situation of seedling burning caused by the contact between fertilizers and seeds.

[0032] Such as Figure 1 , Figure 8 , Figure 9 and Figure 10As shown, the grooving assembly includes a sliding cylinder 14, a connecting plate 15, a hydraulic rod 16, a fixing plate 17, a fixing frame 18, a contact rod 19, a plug plate 191, a second torsion spring 20, a guiding block 21, a sliding rod 22, a pressing ring 23, a limiting ring 24, a second spring 25, an internal thread cylinder 26, an external thread cylinder 261 and a guiding rod 262. Sliding cylinders 14 are slidably connected to the three lower discharging pipes 4 at the rear. A connecting plate 15 is fixedly connected between adjacent two sliding cylinders 14. A hydraulic rod 16 is fixedly connected to the left side of the material box 2. The telescopic end of the hydraulic rod 16 is fixedly connected to a fixing plate 17. The fixing plate 17 is fixedly connected to the adjacent sliding cylinder 14. Four fixing frames 18 are fixedly connected to the lower part of the sliding cylinder 14 and are circumferentially and equally spaced. A plug plate 191 is rotatably connected to the fixing frame 18. The adjacent four plug plates 191 are mutually attached to form a conical shape and enclose the inside of the sliding cylinder 14. A contact rod 19 is fixedly connected to the rotational connection part between the plug plate 191 and the fixing frame 18. Two second torsion springs 20 are connected between the plug plate 191 and the fixing frame 18. Four guiding blocks 21 are fixedly connected to the middle part of the sliding cylinder 14 and are circumferentially and equally spaced. A sliding rod 22 is slidably connected in the guiding block 21. A pressing ring 23 is fixedly connected between the lower sides of the four sliding rods 22. The pressing ring 23 is in pressing cooperation with the contact rod 19. A limiting ring 24 is fixedly connected between the upper sides of the four sliding rods 22. A second spring 25 is connected between the sliding rod 22 and the adjacent guiding block 21. The elastic force of the second spring 25 is greater than that of the second torsion spring 20. Three equally spaced internal thread cylinders 26 are rotatably connected to the rear part of the lower side of the material box 2. An external thread cylinder 261 is connected to the internal thread cylinder 26 through threads. The external thread cylinder 261 is sleeved outside the limiting ring 24. The limiting ring 24 moves downward to contact with the external thread cylinder 261. Three groups of equally spaced guiding rods 262 are fixedly connected to the rear part of the lower side of the material box 2. One group of the guiding rods 262 has two. The two guiding rods 262 in each group are slidably connected to the external thread cylinder 261.

[0033] When the device is walking for sowing, if hill-drop sowing is required, the hydraulic rod 16 will continuously extend and retract. The extension of the hydraulic rod 16 drives the fixed plate 17 to move downward. The downward movement of the fixed plate 17 drives the left sliding cylinder 14 to slide downward. Under the connection of the connecting plate 15, the other two sliding cylinders 14 will also slide downward synchronously. The downward sliding of the sliding cylinder 14 drives the inserting plate 191 to move downward through the fixed frame 18 and insert into the soil to make a hole. When the sliding cylinder 14 slides downward, it will also drive the guide block 21, the sliding rod 22, the extrusion ring 23 and the limiting ring 24 to move downward together. When the limiting ring 24 moves downward to contact the lower part of the external thread cylinder 261, the limiting ring 24 is stuck by the lower part of the external thread cylinder 261. At this time, the sliding rod 22, the extrusion ring 23 and the limiting ring 24 remain stationary and no longer move downward. However, the continuous downward sliding of the sliding cylinder 14 will drive the fixed frame 18, the contact rod 19, the inserting plate 191 and the guide block 21 to continue to move downward. The continuous downward movement of the guide block 21 causes the second spring 25 to deform. The continuous downward movement of the contact rod 19 will be squeezed by the extrusion ring 23 and swing upward. The upward swing of the contact rod 19 drives the inserting plate 191 to rotate outward and open. After the inserting plate 191 rotates outward and opens, the fertilizer in the feeding pipe 4 can fall into the hole made by the inserting plate 191 through the sliding cylinder 14. When the hydraulic rod 16 shortens and drives the fixed plate 17, the sliding cylinder 14 and the connecting plate 15 to move upward, the fixed frame 18, the contact rod 19, the inserting plate 191, the guide block 21, the sliding rod 22, the extrusion ring 23 and the limiting ring 24 will also move upward together with the sliding cylinder 14. Since the elastic force of the second spring 25 is greater than that of the second torsion spring 20, when the sliding cylinder 14 slides upward and resets initially, it will first drive the guide block 21 to slide upward on the sliding rod 22. After the second spring 25 resets, the limiting ring 24 will separate from the external thread cylinder 261, and the extrusion ring 23 will no longer squeeze the contact rod 19. The second torsion spring 20 resets and then drives the inserting plate 191 to rotate inward and close, thus realizing the sequence that the sliding cylinder 14 resets upward first and then the inserting plate 191 closes inward, avoiding the inserting plate 191 closing and grasping a large amount of soil in the deep hole and affecting subsequent feeding. If broadcast sowing is required, after the hydraulic rod 16 extends, it will remain stationary. After the inserting plate 191 inserts into the soil to make a hole, the inserting plate 191 follows the device to move backward, and a strip-shaped groove can be made on the farmland soil. The operator controls the rotation of the internal thread cylinder 26 to drive the up and down movement of the external thread cylinder 261 to adjust the position, thereby adjusting the time of extrusion and cooperation between the limiting ring 24 and the external thread cylinder 261. The earlier the time of extrusion and cooperation between the limiting ring 24 and the external thread cylinder 261 is, the earlier the inserting plate 191 opens. When the extension distance of the hydraulic rod 16 is constant, the downward movement distance of the inserting plate 191 is also constant. Therefore, the earlier the inserting plate 191 opens, the shallower the depth of the fertilizer buried in the soil is.

[0034] Such as Figure 1 And Figure 11As shown in the figure, the soil covering component includes a first mounting plate 27, a first soil covering plate 28, a second mounting plate 29, a sliding plate 30, a second soil covering plate 31, a threaded rod 32, a rotating frame 33, a soil pressing roller 34 and a third torsion spring 35. A first mounting plate 27 is fixedly connected to the middle part of the lower side of the material box 2. Three equally spaced first soil covering plates 28 are fixedly connected to the lower side of the first mounting plate 27. A second mounting plate 29 is fixedly connected to the front part of the lower side of the material box 2. A sliding plate 30 is slidably connected to the second mounting plate 29. Equally spaced second soil covering plates 31 are fixedly connected to the lower side of the sliding plate 30. The first soil covering plate 28 and the second soil covering plate 31 are inclined in opposite directions and are respectively used to push the soil on both sides of the sowing groove. A threaded rod 32 is rotatably connected to the middle part of the second mounting plate 29. The threaded rod 32 is threadedly connected to the sliding plate 30. A rotating frame 33 is rotatably connected to the front part of the sliding plate 30. A soil pressing roller 34 is rotatably connected to the lower part of the rotating frame 33. Two symmetrically arranged third torsion springs 35 are connected between the rotating frame 33 and the sliding plate 30.

[0035] When using this device, after the fertilizer is put into the holes or grooves by the rear feeding pipe 4, the first soil covering plate 28 will move backward together with the device, and then it will push the soil on the left side of the holes or grooves, thus covering the fertilizer first to prevent the seeds behind from directly contacting the fertilizer and causing seedling burning. When the seeds are put into the holes or grooves by the front feeding pipe 4, the second soil covering plate 31 will move backward together with the device and then push the soil on the right side of the holes or grooves, thus covering the seeds. Finally, the soil pressing roller 34 will push and level the whole land. Under the action of the threaded rod 32, the sliding plate 30 can drive the second soil covering plate 31 to move up and down to adjust the height. The lower the second soil covering plate 31 is, the greater the soil pushing amount is, the more soil covers the seeds, and the deeper the planting depth of the seeds is.

[0036] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 12 shown, it further includes a synchronization component for synchronously adjusting the height of the internal threaded cylinder 26. The synchronization component includes a worm gear 36, a second motor 37, a rotating shaft 38 and a worm 381. A worm gear 36 is fixedly connected to the lower part of the internal threaded cylinder 26. A second motor 37 is fixedly connected to the lower left part of the rear side of the material box 2. A rotating shaft 38 is fixedly connected to the output shaft of the second motor 37. Three equally spaced worms 381 are fixedly connected to the rotating shaft 38. The worm 381 meshes with the adjacent worm gear 36.

[0037] When using this device, the second motor 37 drives the rotating shaft 38 to rotate. The rotation of the rotating shaft 38 drives the three worms 381 to rotate synchronously. The rotation of the worm 381 meshes with the worm gear 36 to drive the three internal threaded cylinders 26 to rotate, thereby synchronously adjusting the height of the three external threaded cylinders 261. The operation is simpler and can ensure that the fertilization depth is consistent at the same time.

[0038] As shown Figure 1 and Figure 13 shown, it further includes a blowing assembly for ensuring the fluidity of seeds. The blowing assembly includes a cover plate 39 and a fan 40. The cover plate 39 is rotatably connected to the upper side of the material box 2, the right side of the material box 2 is communicated with the fan 40, and ventilation openings with intercepting nets are provided on both the front and rear sides of the upper part of the material box 2.

[0039] When using this device, the cover plate 39 covers the upper side of the material box 2, which can prevent rainwater from entering the material box 2. The operation of the fan 40 cooperates with the ventilation openings to make the air flow in the material box 2, which can prevent the seeds and fertilizers from agglomerating, reduce static electricity, ensure the fluidity of the seeds and fertilizers, and ensure smooth feeding.

[0040] The above is only the specific implementation manner 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 can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
