Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an all-in-one machine for wheat sowing and fertilizing. Background Art

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

[0003] However, the existing wheat sowing and fertilization integrated machine has certain limitations in function. Most of the existing wheat sowing and fertilization integrated machines can only perform a single sowing mode and cannot flexibly adjust the sowing method according to different agronomic needs. The most common sowing method is row sowing (row sowing refers to evenly spreading seeds on the field to form a continuous strip distribution). This sowing method is suitable for large-scale conventional agricultural production, but in special cases such as agricultural experiments, in order to ensure the utilization rate of seeds and the growth space of plants, a more precise sowing method is required, such as hole sowing (hole sowing refers to concentrated sowing 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 and improve the germination rate of seeds and the growth quality of plants. In actual agricultural production, the soil conditions, climate environment and crop varieties of different plots may be different, so different sowing and fertilization strategies are required. For example, some plots may be more suitable for row sowing, while others may be more suitable for hole sowing. In moist soil, the sowing depth can be appropriately reduced to facilitate germination and avoid root rot. In relatively dry sandy soil, the sowing depth can be increased to ensure that the seeds can be exposed to sufficient water. However, existing machines are unable to switch quickly between these different needs, which limits their scope of application and operating efficiency.

[0004] In order to solve the problem of market launch, we proposed a wheat sowing and fertilization integrated machine. This sowing and fertilization integrated machine can not only switch the sowing method (row sowing or hole sowing) according to actual usage needs, but also adjust the fertilization and sowing depth to meet different agronomic needs. Summary of the invention

DETAILED DESCRIPTION

[0029] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0030] Embodiment 1: A wheat sowing and fertilizing integrated machine, such as Figure 1-Figure 8As shown, it includes a traveling vehicle 1, a material box 2, a partition 3, a feeding pipe 4, a connecting rod 5, a mounting sleeve 6, a feeding 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 slotting component and a covering component. The front part of the traveling vehicle 1 is fixedly connected to the material box 2, the middle part of the material box 2 is fixedly connected to the partition 3, the front and rear parts of the lower side of the material box 2 are connected to three equidistantly distributed feeding pipes 4, the upper part of the feeding pipe 4 is fixedly connected to the mounting sleeve 6, the feeding ball 7 is rotatably connected in the mounting sleeve 6, and the connecting rod 5 is fixedly connected between the two adjacent feeding balls 7 on the left and right, the right part of the lower side of the material box 2 is rotatably connected to two identical connecting rods 5, the feeding ball 7 adjacent to the left end of the connecting rod 5 is fixedly connected, and the extrusion block is slidably connected to the lower part of the mounting sleeve 6 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 discharge ball 7. A contact block 11 is fixedly connected to the side of the opening and closing block 10 close to the extrusion block 8. The extrusion block 8 is a wedge-shaped structure that is flat on the top and inclined on the bottom. The discharge ball 7 and the contact block 11 rotate to squeeze and cooperate with the extrusion block 8. Two transversely symmetrical first torsion springs 12 are connected between the opening and closing block 10 and the discharge 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 to an adjacent connecting rod 5. A pulley group 131 is connected between the front and rear connecting rods 5 rotatably connected to the lower side of the material box 2. A grooving assembly for grooving in the field soil for fertilizing and sowing is provided on the discharge pipe 4 and the material box 2. A covering assembly for covering fertilizer and seeds separately is provided on the material box 2.

[0031] When using the device, the partition 3 separates the material box 2 into two spaces, front and back. The staff puts the fertilizer into the rear space of the material box 2 and the wheat seeds into 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 fertilizer and seeds in the material box 2 enter the feeding pipe 4, thereby filling the feeding ball 7. Then the staff drives the traveling vehicle 1 to move backward, and the backward movement of the traveling vehicle 1 drives the device to move backward. When the device moves backward, the slotting component will be inserted downward according to the sowing method. During the movement of the 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 controlled to rotate counterclockwise continuously. The output shaft of the first motor 13 rotates counterclockwise to drive the feeding ball 7 to rotate counterclockwise continuously 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 installation sleeve 6. The feeding ball 7 continues to rotate counterclockwise to continuously hold a certain amount of fertilizer or seeds to the soil. Pour it down, so that the fertilizer or seed falls into the hole opened by the slotting component through the discharge pipe 4. If row sowing is required, the output shaft of the first motor 13 is controlled to rotate clockwise for a certain stroke. The output shaft of the first motor 13 rotates clockwise through the connecting rod 5 to drive the discharge ball 7 to rotate clockwise. The clockwise rotation of the discharge ball 7 drives the opening and closing block 10 and the contact block 11 to rotate clockwise. The clockwise rotation of the contact block 11 will be squeezed by the squeezing block 8 to swing upward. The upward swing of the contact block 11 drives the opening and closing block 10 to swing downward to open. When the torsion spring 12 is deformed and the opening and closing block 10 swings downward and opens, the fertilizer or seeds can directly pass through the feeding ball 7, so that the feeding pipe 4 can continuously discharge the materials. The feeding method of fertilizer and seeds can be switched by controlling the output shaft of the first motor 13 to rotate clockwise or counterclockwise to adapt to different planting methods. Under the action of the walking direction of the device, the fertilizer will enter the hole before the seeds, and the covering component can cover the soil twice, covering the fertilizer and seeds respectively, to avoid burning the seedlings due to contact between the fertilizer and seeds.

[0032] like Figure 1 , Figure 8 , Fig. 9 and Fig.10As shown, the slotting assembly includes a sliding cylinder 14, a connecting plate 15, a hydraulic rod 16, a fixed plate 17, a fixing frame 18, a contact rod 19, a plug plate 191, a second torsion spring 20, a guide block 21, a sliding rod 22, an extrusion ring 23, a limit ring 24, a second spring 25, an internal threaded cylinder 26, an external threaded cylinder 261 and a guide rod 262. The three feeding tubes 4 at the rear are all slidably connected with the sliding cylinder 14, and the connecting plate 15 is fixedly connected between two adjacent sliding cylinders 14. A hydraulic rod 16 is fixedly connected to the left side of the box 2, and a fixed plate 17 is fixedly connected to the telescopic end of the hydraulic rod 16. The fixed plate 17 is fixedly connected to the adjacent sliding cylinder 14. Four circumferentially equidistant fixed frames 18 are fixedly connected to the lower part of the sliding cylinder 14. A plug plate 191 is rotatably connected to the fixed frame 18. Four adjacent plug plates 191 fit each other in a cone shape and close the interior of the sliding cylinder 14. A contact rod 19 is fixedly connected to the rotatable connection between the plug plate 191 and the fixed frame 18. Two second torsion springs 20 are connected between the plug plate 191 and the fixed frame 18. Four circumferentially equidistant guide blocks 21 are fixedly connected to the middle part of the sliding cylinder 14. A sliding rod 22 is slidably connected in the guide block 21. An extrusion ring 23 is fixedly connected between the lower sides of the four sliding rods 22. The extrusion ring 23 is extruded and matched 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 guide block 21. The second spring 25 is elastic The force is greater than the second torsion spring 20, and three equidistantly distributed internal threaded cylinders 26 are rotatably connected to the rear part of the lower side of the material box 2. The internal threaded cylinder 26 is connected to the external threaded cylinder 261 through a thread. The external threaded cylinder 261 is sleeved on the outside of the limiting ring 24, and the limiting ring 24 moves downward and contacts with the sleeve of the external threaded cylinder 261. Three groups of equidistantly distributed guide rods 262 are fixedly connected to the rear part of the lower side of the material box 2. The guide rods 262 are in a group of two, and the two guide rods 262 in each group are slidably connected to the external threaded cylinder 261.

[0033] When the device is moving for sowing, if hole sowing is required, the hydraulic rod 16 will be continuously extended and retracted, and the extension of the hydraulic rod 16 drives the fixed plate 17 to move downward, and the downward movement of the fixed plate 17 drives the left sliding cylinder 14 to slide downward. Under the action of the connection of the connecting plate 15, the other two sliding cylinders 14 will also slide downward synchronously, and the sliding cylinder 14 will slide downward through the fixed frame 18 to drive the plug plate 191 to move downward and insert into the soil to dig 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 limit ring 24 to move downward together. When the limit ring 24 moves downward to contact with the lower part of the external threaded cylinder 261, the limit ring 24 is stuck by the lower part of the external threaded cylinder 261. When the sliding cylinder 14 continues to slide downward, it will drive the fixed frame 18, the contact rod 19, the plug plate 191 and the guide block 21 to continue to move downward. The guide block 21 continues to move downward to deform the second spring 25. The contact rod 19 continues to move downward and is squeezed by the squeezing ring 23 to swing upward. The contact rod 19 swings upward and drives the plug plate 191 to rotate outward and open. After the plug plate 191 rotates outward and opens, the fertilizer in the feeding pipe 4 can fall into the hole inserted by the plug 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 plate 17, the sliding cylinder 14 and the connecting plate 15 are moved upward. The fixed frame 18, contact rod 19, plug plate 191, guide block 21, sliding rod 22, extrusion ring 23 and limit ring 24 will also move upward with the sliding cylinder 14. Since the elastic force of the second spring 25 is greater than the second torsion spring 20, the sliding cylinder 14 will first drive the guide block 21 to slide upward on the sliding rod 22 at the initial stage of sliding upward reset, so that after the second spring 25 is reset, the limit ring 24 will separate from the external threaded cylinder 261, and the extrusion ring 23 will no longer squeeze the contact rod 19. The reset of the second torsion spring 20 will drive the plug plate 191 to rotate inward and close, thereby realizing the sequence of the sliding cylinder 14 first resetting upward and the plug plate 191 closing inward, avoiding the plug plate 191 closing in the deep hole to grab a large amount of soil and affect For subsequent unloading, if row sowing is required, the hydraulic rod 16 remains stationary after being extended, and after the plug plate 191 is inserted into the soil to make a hole, the plug plate 191 moves backward following the movement of the device, and a strip groove can be opened on the soil. The staff controls the rotation of the internal threaded tube 26 to drive the external threaded tube 261 to move up and down to adjust the position, thereby adjusting the time for the limit ring 24 and the external threaded tube 261 to be squeezed and matched. The earlier the limit ring 24 and the external threaded tube 261 are squeezed and matched, the earlier the plug plate 191 opens. When the extension distance of the hydraulic rod 16 is constant, the downward movement distance of the plug plate 191 is also constant. Therefore, the earlier the plug plate 191 is opened, the shallower the depth of the fertilizer buried in the soil.

[0034] like Figure 1 and Fig.11As shown, the soil covering assembly 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. The first mounting plate 27 is fixedly connected to the middle of the lower side of the material box 2, and three equidistantly distributed first soil covering plates 28 are fixedly connected to the lower side of the first mounting plate 27. The second mounting plate 29 is fixedly connected to the front part of the lower side of the material box 2. The sliding plate 30 is slidably connected to the second mounting plate 29. The sliding plate A second soil covering plate 31 is fixedly connected to the lower side of 30 and is equidistantly distributed. 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 connected to the sliding plate 30 by threads. 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 third torsion springs 35 symmetrically connected to the rotating frame 33 and the sliding plate 30 are connected.

[0035] When the device is used, after the rear feeding pipe 4 puts the fertilizer into the hole or groove, the first covering plate 28 moves backward with the movement of the device and pushes the soil on the left side of the hole or groove into it, thereby covering the fertilizer first to prevent the seeds from directly contacting the fertilizer and causing seedling burn. After the front feeding pipe 4 puts the seeds into the hole or groove, the second covering plate 31 moves backward with the movement of the device and pushes the soil on the right side of the hole or groove into it, thereby covering the seeds. Finally, the soil pressing roller 34 is used to press the land flat as a whole. Under the action of the threaded rod 32, the sliding plate 30 can drive the second covering plate 31 to move up and down to adjust the height. The lower the second covering plate 31 is, the greater the amount of soil pushed, the more soil covers the seeds, and the deeper the planting depth of the seeds.

[0036] Embodiment 2: Based on embodiment 1, Figure 1 and Fig.12 As shown, it also includes a synchronization component for synchronously adjusting the height of the internal threaded barrel 26, the synchronization component includes a worm gear 36, a second motor 37, a rotating shaft 38 and a worm 381, the lower part of the internal threaded barrel 26 is fixedly connected to the worm gear 36, the lower left part of the rear side of the material box 2 is fixedly connected to the second motor 37, the output shaft of the second motor 37 is fixedly connected to the rotating shaft 38, and three equidistantly distributed worms 381 are fixedly connected to the rotating shaft 38, and the worm 381 is meshed with the adjacent worm gear 36.

[0037] When the device is used, the second motor 37 drives the rotating shaft 38 to rotate, and the rotation of the rotating shaft 38 drives the three worms 381 to rotate synchronously. The rotation of the worm 381 and the worm wheel 36 drive the three internal threaded cylinders 26 to rotate, and then the heights of the three external threaded cylinders 261 are synchronously adjusted. The operation is simpler and the fertilization depth can be ensured to be consistent.

[0038] like Figure 1 and Fig.13 As shown, it also includes a blowing assembly for ensuring seed fluidity, 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 fan 40 is connected to the right side of the material box 2, and ventilation holes with interception nets are provided on the front and rear sides of the upper part of the material box 2.

[0039] When the device is used, the cover plate 39 covers the upper side of the material box 2 to prevent rainwater from entering the material box 2, and the fan 40 cooperates with the vent to allow air to circulate in the material box 2, which can prevent seeds and fertilizers from clumping and reduce static electricity, thereby ensuring the fluidity of seeds and fertilizers and ensuring smooth feeding.

[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
