Description

Technical Field

[0001] The present invention relates to the technical field of crop planting, and particularly relates to an integrated automatic device for crop planting and fertilization. Background Art

[0002] In modern agricultural production, the emergence of integrated automatic devices for crop planting and fertilization has greatly improved the efficiency and accuracy of agricultural production. Traditional crop planting methods mostly rely on manual operation or semi-automatic mechanical equipment, which not only consumes a large amount of human resources but also makes it difficult to ensure the consistency and accuracy of the fertilization and planting processes. With the progress of technology, various automatic devices have been introduced into agricultural production to improve work efficiency, reduce labor input, and optimize resource utilization.

[0003] However, when the existing crop planting equipment is in use, the common practice is to directly pour the fertilizer on the soil surface and then mix the fertilizer and the soil evenly through mechanical agitation. Although this fertilization method seemingly can ensure sufficient contact between the fertilizer and the soil, since the fertilizer is directly exposed on the soil surface, it is easily affected by natural factors such as rain erosion, direct sunlight, and wind erosion, resulting in the loss of soil fertility, thereby reducing the effective utilization rate of the fertilizer. Moreover, crop seedlings are usually planted at a certain interval, which means that the fertilizer in the soil area between two crop seedlings may not be effectively absorbed because the roots are mainly concentrated around the plants, and the fertilizer far from the plants may not be utilized for a long time, causing waste of fertilizer resources. In addition, after the existing crop planting equipment transports the crop seedlings to the pre-dug holes, it is necessary to cover the soil to fix the crop seedlings, but it is easy to occur that the soil particles are stirred onto the leaves of the crop seedlings. This situation not only affects the photosynthesis of the crops but also may cause the leaves to rot due to the humid environment, thereby affecting the healthy growth and final yield of the crops. Summary of the Invention

[0004] In view of this, the present invention provides an integrated automatic device for crop planting and fertilization, which can overcome the drawbacks that when the existing crop planting equipment is in use, the soil particles are stirred onto the leaves of the crop seedlings, resulting in the leaves of the crop seedlings being prone to rot and the fertilizer utilization rate being relatively low.

On the left side of the top of the mobile trolley 1, the fixed frames 16 are symmetrically connected front and back. On the left side of the top of the two fixed frames 16, long holes 1601 are opened. On the upper part of the two fixed frames 16, the lifting frames 17 are slidably connected. On the two lifting frames 17, the conveyors 18 are installed, and the conveyors 18 are located directly below the long holes 1601, so that the crop seedlings can fall down through the long holes 1601 onto the conveyors 18. On the upper part of the right side of the two fixed frames 16, the second electric push rods 19 are connected, and the telescopic rods of the second electric push rods 19 are connected to the lifting frames 17. On the upper part of the side where the two fixed frames 16 are close to each other, the blanking pipes 20 are connected. The blanking pipes 20 are located directly above the through holes on the mobile trolley 1, and the close ends of the two conveyors 18 are located inside the upper part of the blanking pipes 20, so that the conveyors 18 can convey the crop seedlings into the blanking pipes 20 for seedling feeding. On the mobile trolley 1, a material transfer assembly is provided for moving the crop seedlings to the long holes 1601; the material transfer assembly includes a guiding frame 21, a placing frame 22, a third electric push rod 23, a seedling tray 24, a fourth electric push rod 25 and a sliding clamp 26. On the left side of the top of the mobile trolley 1, the guiding frames 21 are symmetrically connected front and back. The guiding frames 21 are located on the left side of the fixed frames 16. On the upper part of the guiding frames 21, the placing frames 22 are slidably connected. On the top of the guiding frames 21, two third electric push rods 23 are symmetrically connected front and back, and the telescopic rods of the two third electric push rods 23 are connected to the placing frames 22. On the placing frames 22, the seedling trays 24 are vertically and spacedly placed. The seedling tray 24 is composed of a bottom frame 2401, a sliding frame 2402 and a seedling growing frame 2403. On the front and back sides of the inner wall of the bottom frame 2401, sliding grooves are opened. The sliding frame 2402 is slidably connected in the sliding grooves of the bottom frame 2401. The shape of the sliding frame 2402 is rectangular, and protrusions are provided on the front and back sides of the right side of the sliding frame 2402. Inside the sliding frame 2402, the seedling growing frame 2403 is connected. The seedling growing frame 2403 is composed of a plurality of independent cylindrical tubes. The top and bottom of each cylindrical tube are designed with openings, which is convenient for the growth and removal of the crop seedlings, ensuring that each crop seedling can be independently placed and easily separated. In the middle of the front and back sides of the guiding frames 21, the fourth electric push rods 25 are connected. In the middle of the front and back sides of the guiding frames 21, the sliding clamps 26 are also slidably connected.

[0033] As Figure 7 and Figure 10As shown, the positioning mechanism includes a second lifting plate 27, a first linear actuator 28, a connecting cylinder 29, a connecting pipe 30, a rotating claw 31, an elastic rope 3101 and an opening and closing assembly. On the lower part of the mutually approaching sides of the two guiding frames 21, a second lifting plate 27 is slidably connected. On the left parts of the two second lifting plates 27, a first linear actuator 28 is connected, and the telescopic rod of the first linear actuator 28 is connected to the mobile trolley 1. On the right parts of the two second lifting plates 27, a connecting cylinder 29 is connected. Inside the two connecting cylinders 29, a connecting pipe 30 is connected. The inner wall of the connecting pipe 30 is in sliding contact with the outer wall of the blanking pipe 20 and remains connected. At the lower end of the connecting pipe 30, a plurality of rotating claws 31 are circumferentially and spacedly rotatably connected, so that the crop seedlings in the blanking pipe 20 can fall down along the connecting pipe 30 onto the rotating claws 31. An elastic rope 3101 is spacedly connected between adjacent two rotating claws 31. The elastic rope 3101 can automatically adjust its length when the rotating claws 31 open and close. The elastic rope 3101 is used to block the leaves of the crop seedlings on the rotating claws 31, and can ensure that the stems and leaves of the crop seedlings will not be damaged during the soil covering process. An opening and closing assembly for controlling the rotation and opening and closing of the rotating claws 31 is provided on the connecting pipe 30; the opening and closing assembly includes a second linear actuator 32, a sleeve 33, a guide rail 34 and a short rod 35. On the lower parts of the left and right sides of the connecting pipe 30, a second linear actuator 32 is connected. The lower part of the outer wall of the connecting pipe 30 is slidably connected with a sleeve 33. Vertical holes 3301 are opened on the left and right sides of the sleeve 33. The second linear actuator 32 passes through the vertical holes 3301, and the telescopic rod of the second linear actuator 32 is connected to the upper part of the outer wall of the sleeve 33. A plurality of guide rails 34 are circumferentially and spacedly connected to the lower part of the outer wall of the sleeve 33. As Figure 10 shown, the chute on the guide rail 34 is inclined. At the upper end of each rotating claw 31, a short rod 35 is connected. The short rods 35 correspond to the guide rails 34 one by one, and the short rods 35 all slide in the chute on the corresponding guide rail 34, so that when the guide rail 34 moves up and down, the guide rail 34 can squeeze the short rod 35 to move in a direction close to or away from the axis of the sleeve 33, thereby controlling the rotation and opening and closing of the rotating claw 31.

[0034] As Figure 11As shown in the figure, the soil covering mechanism includes a rotating shovel plate 36, a return spring 3601, a roller 37, a third linear actuator 38 and a lifting sleeve 39. Four rotating shovel plates 36 are symmetrically connected to the bottom of each of the two connecting cylinders 29. The four rotating shovel plates 36 are arranged in a rectangular distribution, and the rotating shovel plate 36 is located outside the rotating claw 31, so that the rotation of the rotating shovel plate 36 can push the soil towards the direction close to the rotating claw 31. The two ends of the return spring 3601 are respectively connected to the upper part of the rotating shovel plate 36 and the outer wall of the connecting cylinder 29. Rollers 37 are rotatably connected to the upper parts of the rotating shovel plates 36. Two third linear actuators 38 are symmetrically connected to the upper part of the outer wall of the connecting cylinder 29. The middle part of the outer wall of the connecting cylinder 29 is slidably connected with a lifting sleeve 39. The outer wall of the lifting sleeve 39 is a slope and contacts the roller 37, and the telescopic rod of the third linear actuator 38 is connected to the top of the lifting sleeve 39.

[0035] As Figure 11 and Figure 12 shown in the figure, it also includes a nozzle 40, an annular pipe 41, a water pipe 42, a water tank 43 and a water pump 44. Nozzles 40 are installed in the middle of each rotating shovel plate 36. An annular pipe 41 is connected between the four nozzles 40 on the same connecting cylinder 29 and kept in communication. Water pipes 42 are connected to the left sides of the two annular pipes 41 and kept in communication. A water tank 43 is connected to the top left side of the mobile trolley 1. The water tank 43 is located on the left side of the guide frame 21, and a water pump 44 is installed on the lower right side of the water tank 43. The water inlet of the water pump 44 is communicated with the bottom of the water tank 43. The left ends of the two water pipes 42 are both communicated with the water outlet of the water pump 44.

[0036] In the initial state, the loading tank 3 is pre-filled with fertilizer, and the fertilizer will gradually fall into the rotating cylinder 8 due to the action of gravity. At the same time, the water tank 43 is also pre-filled with a certain amount of water to prepare for subsequent irrigation. First, control the mobile trolley 1 to move to the designated position, and then place multiple seedling trays 24 on the placement rack 22 (as Figure 7As shown, the protrusion on the sliding frame 2402 of the lowermost seedling tray 24 is placed within the groove 2601 of the sliding clamp 26. Then, the first electric push rod 6 drives the first lifting plate 5 to move downward. The first lifting plate 5 can drive the hollow rotating platform 7 and the rotating cylinder 8 to move downward. The rotating cylinder 8 can drive the drill bit 9 and the hollow push rod 10 to move downward. Meanwhile, the hollow rotating platform 7 can be used to drive the rotating cylinder 8 to rotate horizontally. The rotating cylinder 8 can drive the drill bit 9 and the hollow push rod 10 to rotate horizontally. Moreover, the driving motor 13 can be used to drive the rotating rod 14 to rotate. The rotating rod 14 can drive the screw rod 12 to rotate self - identically through the bevel gear assembly 15. The self - rotation of the screw rod 12 can convey the fertilizer inside the rotating cylinder 8 downward into the hollow push rod 10. Subsequently, the drill bit 9 and the hollow push rod 10 will insert into the soil. The horizontal rotation of the drill bit 9 can dig a hole in the soil. Meanwhile, the fertilizer inside the hollow push rod 10 will fall into the soil through the notch 1001. At the same time, the horizontal rotation of the hollow push rod 10 can evenly convey the fertilizer to the periphery of the hole. Also, the hollow push rod 10 can stir the soil and fertilizer around the hole evenly. Subsequently, the first electric push rod 6 can be used to drive the first lifting plate 5 to move upward to reset. The first lifting plate 5 can drive the hollow rotating platform 7 and the rotating cylinder 8 to move upward to reset. The rotating cylinder 8 can drive the drill bit 9 and the hollow push rod 10 to move upward to reset and separate from the soil. And the hollow rotating platform 7 and the driving motor 13 can be controlled to stop working. Then, control the mobile trolley 1 to move rightward by a specified distance, so that the rotating claw 31 moves directly above the hole. Repeat the above operations to dig a second hole in the soil. During the process of this equipment digging the second hole in the soil, the fourth electric push rod 25 can be used to drive the sliding clamp 26 to move rightward by a specified distance. The sliding clamp 26 will pull the lowermost sliding frame 2402 to move rightward. The sliding frame 2402 will drive the seedling - raising frame 2403 to move rightward to the left side of the top of the fixed frame 16, so that the bottom frame 2401 no longer blocks the bottom of the seedling - raising frame 2403, while the top of the fixed frame 16 will block the bottom of the seedling - raising frame 2403. Subsequently, the right - most row of crop seedlings inside the seedling - raising frame 2403 will move directly above the linear hole 1601. At this time, the seedling - raising frame 2403 stops moving rightward, and the right - most row of crop seedlings inside the seedling - raising frame 2403 will fall downward due to gravity onto the top of the conveyor 18. Subsequently, the second electric push rod 19 can be used to drive the lifting frame 17 and the conveyor 18 to move downward. The conveyor 18 can drive the crop seedlings thereon to move downward and separate from the seedling - raising frame 2403. Then, the conveyors 18 on the front and back sides can intermittently convey the crop seedlings thereon toward the mutually approaching sides, so that each crop seedling can intermittently fall into the blanking pipe 20, and fall downward along the blanking pipe 20 and the connecting pipe 30 onto the rotating claw 31. Then, the first linear actuator 28 is used to drive the second lifting plate 27 to move downward by a specified distance, which can drive the connecting cylinder 29, the connecting pipe 30 and the rotating claw 31 to move downward by a specified distance. The connecting cylinder 29 can drive the rotating shovel plate 36 to move downward by a specified distance, so that the lower end of the rotating shovel plate 36 inserts into the soil.The rotating claw 31 can drive the crop seedlings thereon to move downward a specified distance to directly above the pit, and then drive the sleeve 33 to move upward a specified distance through the second linear driver 32. The sleeve 33 can drive the guide rail 34 to move upward a specified distance. The guide rail 34 can push the short rod 35 to move in the direction close to the axis of the sleeve 33, thereby driving the upper end of the rotating claw 31 to move in the direction close to the axis of the sleeve 33, causing the rotating claw 31 to rotate. At this time, the lower end of the rotating claw 31 will move away from the axis of the sleeve 33, causing the lower end of the rotating claw 31 to open slightly, and the elastic rope 3101 is stretched. At this time, the crop seedlings on the rotating claw 31 will fall downward into the pit. The soil block of the crop seedlings is located in the pit, while the stem and leaf parts of the crop seedlings are located on the rotating claw 31. The elastic rope 3101 can block the stem and leaf parts of the crop seedlings to prevent the stem and leaf parts of the crop seedlings from protruding from the gap between two adjacent rotating claws 31. Then, the lifting sleeve 39 can be driven to move downward through the third linear driver 38. The lifting sleeve 39 will squeeze the roller 37 to move away from the axis of the connecting cylinder 29. The roller 37 will drive the upper end of the rotating shovel plate 36 to move away from the axis of the connecting cylinder 29, causing the rotating shovel plate 36 to rotate, and the return spring 3601 is stretched. At this time, the lower end of the rotating shovel plate 36 will move in the direction close to the axis of the connecting cylinder 29, so as to stir the soil around the pit into the pit to fix the crop seedlings in the pit. Since the rotating claw 31 blocks the periphery of the stem and leaf parts of the crop seedlings, it can prevent the stem and leaf parts of the crop seedlings from contacting the soil during the process of covering the soil. Then, an appropriate amount of water in the water tank 43 can be conveyed to the nozzle 40 through the water pipe 42 and the annular pipe 41 by the water pump 44, and the water is irrigated into the soil in the pit through the nozzle 40. Then, drive the sleeve 33 to move upward again through the second linear driver 32, drive the lower end of the rotating claw 31 to completely open and move away from the stem and leaf parts of the crop seedlings, and then drive the second lifting plate 27 to move upward and reset through the first linear driver 28, which can drive the connecting cylinder 29, the connecting pipe 30 and the rotating claw 31 to move upward and reset. The connecting cylinder 29 can drive the rotating shovel plate 36 to move upward and reset to separate from the soil. At the same time, the lifting sleeve 39 can be driven to move upward and reset through the third linear driver 38, so that the lifting sleeve 39 is separated from the roller 37, and the return spring 3601 will return to its original state, driving the rotating shovel plate 36 to reverse and reset. Then, drive the sleeve 33 to move downward and reset through the second linear driver 32, and at the same time, drive the lower end of the rotating claw 31 to close to pick up the next crop seedling. The elastic rope 3101 will also return to its original state. In this way, when all the crop seedlings on a seedling tray 24 are planted, the seedling tray 24 will be located at the top of the fixing frame 16, and the seedling tray 24 is separated from the placing frame 22. Workers can take away the seedling tray 24, and drive the sliding clamp 26 to move leftward and reset through the fourth electric push rod 25. Then, drive the placing frame 22 to move downward a specified distance through the third electric push rod 23. The placing frame 22 can drive the other seedling trays 24 thereon to move downward a specified distance.Place the protrusion on the sliding frame 2402 of the next seedling tray 24 within the groove 2601 of the sliding clamp 26, so that the entire device can complete the tasks of digging holes and planting seedlings simultaneously, improving work efficiency.
