Description

Technical Field

[0001] This utility model relates to the field of soybean planting technology, specifically a soybean breeding transplanting device. Background Technology

[0002] Soybean cultivation refers to the entire agricultural production process in which humans cultivate soybean seeds into mature plants through a series of artificial interventions and management activities in order to obtain soybean grains (soybean meal, soybean oil, etc.) or for other uses.

[0003] An existing patent (publication number: CN223322468U) discloses a soybean seedling transplanting device, relating to the technical field of seedling transplanting devices. It includes a trolley, with a bearing fixedly inserted into the inner wall of the trolley. A rotating shaft is fixedly inserted inside the bearing, and a first gear is fixedly sleeved on the outer wall of the rotating shaft. A second gear is meshed with the inner wall of the first gear. In this invention, through the interaction of the various components of the device and the drive of a drive motor, soybean seedlings are uniformly transported into the feed hopper. Subsequently, under the precise drive of a first cylinder and a double-acting cylinder, two conical plates can smoothly unfold outwards, effectively turning over the soil covering the seedlings. During this process, the seedlings naturally fall into the gaps in the turned-over soil. This continuous automated seedling transplanting method eliminates the traditional cumbersome manual seedling transplanting operation, greatly reducing labor intensity and significantly improving the overall efficiency of the seedling transplanting work.

[0004] The aforementioned device can reduce labor intensity and improve the overall efficiency of seedling transplanting. However, in actual use, it can only transplant seedlings into ditches and complete the soil covering work by moving the cart. It is not convenient to replenish fertilizer and irrigation water to the roots of the seedlings in a timely manner. Therefore, after transplanting, additional manpower and equipment are needed for topdressing and watering, which increases the subsequent work process and labor costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a soybean seedling transplanting device that has the advantages of simultaneous seedling transplanting, fertilization, and irrigation, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a soybean breeding transplanting device, comprising a first steel frame and a second steel frame, wherein brackets are fixedly installed on both sides of the first steel frame along its width direction by bolts, and a bearing platform is fixedly installed on the upper surface of the two brackets, and a seedling placement mechanism is provided on the bearing platform, the seedling placement mechanism comprising a conical frame fixedly installed on the first steel frame;

[0007] One of the supports has a fertilizer application component fixedly installed on its upper surface for fertilizing and watering the roots of the seedlings. The fertilizer application component is connected to the seedling feeding mechanism through a drive mechanism. The upper surface of the first steel frame is also equipped with a liquid storage component connected to the fertilizer application component for diluting and storing fertilizer.

[0008] The fertilizer application assembly includes an inlet cylinder fixedly mounted on the upper surface of the support. A piston rod is slidably connected inside the inlet cylinder. A stainless steel spring is fixedly connected between the bottom end of the piston rod and the inner wall of the inlet cylinder. A drain pipe is fixedly connected to the bottom end of the inlet cylinder. A one-way valve for draining is fixedly installed on the circumference of the drain pipe. The drain end of the drain pipe corresponds to the bottom end of the conical frame.

[0009] Furthermore, the seedling feeding mechanism also includes a rotating frame disposed above the upper surface of the support platform. The rotating frame is coaxially disposed with the support platform. Multiple transport frames are fixedly installed on the circumferential surface of the rotating frame by fasteners. Each transport frame has a bottom cover hinged to its bottom end by a hinge.

[0010] The circumferential surface of the support platform is provided with a discharge groove, which corresponds to the position of the conical frame.

[0011] The above scheme allows the rotating frame to keep the bottom cover of multiple transport frames in contact with the support platform during its rotation, thereby sealing the bottom of the transport frame. When the transport frame moves to the discharge trough, the bottom cover will open under the action of gravity, allowing the seedlings inside the transport frame to fall into the conical frame and enter the cultivated ditch through the conical frame.

[0012] Furthermore, the driving mechanism includes a driving rod fixedly installed in the central area of ​​the bottom surface of the rotating frame. The driving rod is rotatably connected to the support platform and extends out of the support platform. A worm wheel is fixedly installed on the circumferential surface of one end of the driving rod that extends out of the support platform. A worm is rotatably connected between the two brackets, and the worm and the worm wheel are meshed together.

[0013] A cam is also fixedly installed on the circumference of the worm gear, and the upper end of the piston rod has a spherical structure that contacts the cam.

[0014] With the above scheme, when the worm rotates, it drives the cam to rotate. The cam pushes the piston rod up and down through its contour, thereby squeezing and sucking the fertilizer solution in the inlet cylinder, ensuring that the fertilization component and the seedling feeding mechanism work synchronously.

[0015] Furthermore, the liquid storage assembly includes a liquid storage tank fixedly installed on a first steel frame. The inner walls of both sides of the liquid storage tank along its axial direction are rotatably connected to a stirring rod via a sealed bearing. A handle is fixedly installed at one end of the stirring rod. A replenishment pipe is fixedly connected to the circumference of the liquid storage tank, and a sealing valve is fixedly installed on the circumference of the replenishment pipe.

[0016] The inlet cylinder is fixedly connected to an inlet pipe on its circumference, and the other end of the inlet pipe is fixedly connected to a storage tank. A one-way valve for inlet is also fixedly installed on the circumference of the inlet pipe.

[0017] The above scheme allows fertilizer or water to be added to the storage tank via a replenishment pipe. A sealing valve controls the opening and closing of the replenishment pipe. By turning the handle, the stirring rod can be rotated to mix and dilute the fertilizer and water in the storage tank. A one-way valve ensures that the fertilizer solution can only flow from the storage tank into the inlet cylinder in one direction.

[0018] Furthermore, the bottom end of the first steel frame is fixedly connected to a trenching shovel and two covering shovels;

[0019] The trenching shovel and the two covering shovels are positioned correspondingly. The trenching shovel has an arc-shaped structure, and the two covering shovels are combined to form a V-shaped structure.

[0020] The above method involves using a trenching shovel to dig trenches in the soil to place seedlings, and a covering shovel to cover the roots of the seedlings with soil after they have been placed.

[0021] Furthermore, a travel steering mechanism is provided between the first steel frame and the second steel frame, and the travel steering mechanism is connected to the drive mechanism.

[0022] Furthermore, the travel and steering mechanism includes a support frame formed on one side of the first steel frame along its length direction. A connector for connecting to an external traction device is fixedly installed on one side of the support frame. A rotating rod is rotatably connected between the two sides of the support frame along its length direction. Traveling wheels are fixedly installed at both ends of the rotating rod. A sprocket is fixedly installed on the circumferential surface of the rotating rod and one end of the worm gear. The two sprockets are connected by a chain drive.

[0023] The above scheme uses chain drive to drive the rotating rod and sprocket when the traveling wheel rotates, which in turn drives the worm gear to rotate, thus realizing the linkage between the seedling feeding mechanism and the fertilizer application component.

[0024] Furthermore, the travel steering mechanism also includes steering wheels rotatably connected to both sides of the second steel frame along its length. The first steel frame and the second steel frame are respectively provided with fixing members on their corresponding sides. The two fixing members are coaxially arranged, and the upper surfaces of the two fixing members are respectively provided with limit grooves. A positioning rod with a T-shaped structure is inserted between the two limit grooves.

[0025] Through the above scheme, the positioning rod can connect the first steel frame and the second steel frame through the fixing component, so that the first steel frame and the second steel frame can rotate relative to each other, thereby realizing the steering function of the device.

[0026] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0027] This soybean breeding transplanting device, through its seedling placement mechanism, sequentially places seedlings into planting furrows in the soil during overall movement. With the assistance of a drive mechanism, fertilizer from the inlet cylinder is delivered directly to the roots of the seedlings. Because the fertilizer is diluted by the storage component, it will not damage or burn the seedling roots. By discharging irrigation water and fertilizer together into the seedling roots, it simultaneously fertilizes and irrigates the seedlings, thereby ensuring a high survival rate and promoting their growth.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Please see Figures 1-6 The soybean breeding transplanting device in this embodiment includes a first steel frame 1 and a second steel frame 2. The first steel frame 1 has brackets 3 fixedly installed on both sides along its width direction by bolts. The upper surfaces of the two brackets 3 are fixedly installed with a bearing platform 4. The bearing platform 4 is provided with a seedling placement mechanism 5. The seedling placement mechanism 5 includes a conical frame 501 fixedly installed on the first steel frame 1.

[0048] One of the supports 3 has a fertilizer application component 6 fixedly installed on its upper surface for fertilizing and watering the roots of the seedlings. The fertilizer application component 6 is connected to the seedling feeding mechanism 5 through a drive mechanism 7. The upper surface of the first steel frame 1 is also provided with a liquid storage component 8 connected to the fertilizer application component 6 for diluting and storing fertilizer.

[0049] The fertilizer applicator 6 includes an inlet cylinder 601 fixedly mounted on the upper surface of the support 3. A piston rod 602 is slidably connected inside the inlet cylinder 601. A stainless steel spring 603 is fixedly connected between the bottom end of the piston rod 602 and the inner wall of the inlet cylinder 601. A drain pipe 604 is fixedly connected to the bottom end of the inlet cylinder 601. A drain check valve 605 is fixedly mounted on the circumferential surface of the drain pipe 604. The drain end of the drain pipe 604 corresponds to the bottom end of the conical frame 501. Through the cooperation of the inlet cylinder 601 and the piston rod 602, the entire assembly can move. During the movement of the assembly, the piston rod 602 slides inside the inlet cylinder 601, squeezing the diluent inside the inlet cylinder 601. The fertilizer is diluted by the irrigation water and discharged into the roots of the seedlings through the drainage pipe 604. Since the fertilizer is diluted by the irrigation water, it will not damage the roots of the seedlings or cause root burn. By discharging the irrigation water and fertilizer into the roots of the seedlings together, the purpose of fertilizing and watering the seedlings can be achieved at the same time, thereby ensuring the survival rate of the seedlings and promoting their growth. The bottom end of the first steel frame 1 is fixedly connected to a trenching shovel 9 and two covering shovels 10. The trenching shovel 9 and the two covering shovels 10 are in corresponding positions. The trenching shovel 9 has an arc-shaped structure, and the two covering shovels 10 are combined to form a V-shaped structure. The trenching shovel 9 is used to dig trenches in the soil to place the seedlings, and the covering shovels 10 are used to cover the roots of the seedlings with soil after they are placed.

[0050] The seedling feeding mechanism 5 also includes a rotating frame 502 mounted above the upper surface of the support platform 4. The rotating frame 502 is coaxially mounted with the support platform 4. Multiple transport frames 503 are fixedly mounted on the circumferential surface of the rotating frame 502 by fasteners. The bottom end of each transport frame 503 is hinged to a bottom cover 504. The circumferential surface of the support platform 4 is provided with a discharge groove 505, which corresponds to the position of the conical frame 501. The rotating frame 502 can keep the bottom covers 504 on the multiple transport frames 503 in contact with the support platform 4 during its rotation, thereby sealing the bottom of the transport frames 503. When the transport frame 503 moves to the discharge groove 505, the bottom cover 504 will open under the action of gravity, allowing the seedlings inside the transport frame 503 to fall into the conical frame 501 and enter the cultivated ditch through the conical frame 501.

[0051] The drive mechanism 7 includes a drive rod 701 fixedly installed in the central area of ​​the bottom surface of the rotating frame 502. The drive rod 701 is rotatably connected to the support platform 4 and extends out of the support platform 4. A worm gear 702 is fixedly installed on the circumferential surface of one end of the drive rod 701 that extends out of the support platform 4. A worm 703 is rotatably connected between the two brackets 3. The worm 703 is meshed with the worm gear 702. A cam 704 is also fixedly installed on the circumferential surface of the worm 703. The upper end of the piston rod 602 has a spherical structure and contacts the cam 704. When the worm 703 rotates, it drives the cam 704 to rotate. The cam 704 pushes the piston rod 602 up and down through its contour, thereby squeezing and sucking the fertilizer solution in the liquid inlet cylinder 601, ensuring that the fertilization component 6 and the seedling feeding mechanism 5 work synchronously.

[0052] The liquid storage assembly 8 includes a liquid storage tank 801 fixedly mounted on a first steel frame 1. A stirring rod 802 is rotatably connected to the inner walls of both sides of the liquid storage tank 801 along its axial direction via sealed bearings. A handle is fixedly mounted on one end of the stirring rod 802. A replenishment pipe 803 is fixedly connected to the circumferential surface of the liquid storage tank 801. A sealing valve 804 is fixedly mounted on the circumferential surface of the replenishment pipe 803. An inlet pipe 805 is fixedly connected to the circumferential surface of the inlet cylinder 601. The other end of the inlet pipe 805... The end is fixedly connected to the storage tank 801, and the circumferential surface of the inlet pipe 805 is fixedly installed with an inlet check valve 806. Fertilizer or water can be added to the storage tank 801 through the replenishment pipe 803. The sealing valve 804 is used to control the opening and closing of the replenishment pipe 803. By turning the handle, the stirring rod 802 can be rotated to mix and dilute the fertilizer and water in the storage tank 801. The inlet check valve 806 ensures that the fertilizer solution can only flow from the storage tank 801 into the inlet cylinder 601 in one direction.

[0053] A travel steering mechanism 11 is provided between the first steel frame 1 and the second steel frame 2. The travel steering mechanism 11 is connected to the drive mechanism 7. The travel steering mechanism 11 includes a support frame 1101 formed on one side of the first steel frame 1 along its length. A connector 1102 for connecting to an external traction device is fixedly installed on one side of the support frame 1101. A rotating rod 1103 is rotatably connected between the two sides of the support frame 1101 along its length. Travel wheels 1104 are fixedly installed at both ends of the rotating rod 1103. A sprocket 1105 is fixedly installed on the circumferential surface of the rotating rod 1103 and one end of the worm gear 703. The two sprockets 1105 are connected by a chain drive. When the travel wheel 1104 rotates, it drives the rotating wheel 703 to rotate. The rod 1103 and sprocket 1105 drive the worm gear 703 to rotate, thereby realizing the linkage between the seedling feeding mechanism 5 and the fertilizer application component 6. The travel and steering mechanism 11 also includes steering wheels 1106 that are rotatably connected to both sides of the second steel frame 2 along its length. The first steel frame 1 and the second steel frame 2 are respectively provided with fixing members 1107 on their corresponding sides. The two fixing members 1107 are coaxially arranged, and the upper surfaces of the two fixing members 1107 are respectively provided with limit grooves 1108. A positioning rod 1109 with a T-shaped structure is inserted between the two limit grooves 1108. The positioning rod 1109 can connect the first steel frame 1 and the second steel frame 2 through the fixing members 1107, so that the first steel frame 1 and the second steel frame 2 can rotate relative to each other, thereby realizing the steering function of the device.

[0054] The working principle of the above embodiment is as follows: In the preparation work, fertilizer and irrigation water are put into the storage tank 801 through the replenishment pipe 803. Then, the replenishment pipe 803 is sealed by the sealing valve 804. The operator turns the handle to make the handle drive the stirring rod 802 to move inside the storage tank 801, which can realize the mixing of fertilizer and irrigation water in the storage tank 801, thereby achieving the purpose of diluting fertilizer.

[0055] When transplanting soybean seedlings, the worker connects connector 1102 to an external traction device. The seedlings are then placed sequentially into multiple transport frames 503. When the external traction device operates, it drives the first steel frame 1 to move. Through the cooperation of the traveling wheels 1104 and steering wheels 1106, the entire structure moves. At this time, the trenching shovel 9 can be inserted into the soil and trenches as it moves with the traction device. When the two traveling wheels 1104 move, they drive the rotating rod 1103 to rotate, and through the sprocket 1105... The chain drive causes the worm 703 to rotate. During the rotation, the worm 703 can mesh with the worm wheel 702, which in turn drives the drive rod 701 to rotate. During the rotation, the drive rod 701 can drive the rotating frame 502 to rotate synchronously. During the rotation, the rotating frame 502 can drive multiple transport frames 503 to move. When the transport frame 503 containing the seedlings moves to the discharge trough 505, the bottom cover 504 of the transport frame 503 will open under the action of gravity, allowing the seedlings to enter the conical frame 501 and then enter the cultivated ditch through the conical frame 501.

[0056] As the worm gear 703 rotates, the cam 704 rotates synchronously with it. The raised profile of the cam 704 pushes the piston rod 602 within the inlet cylinder 601, compressing the mixed fertilizer and stainless steel spring 603 inside. This allows the mixed fertilizer to be discharged through the drain valve 605 and drain pipe 604 into the roots of the transplanted seedlings, simultaneously achieving fertilization and irrigation. Because the fertilizer is diluted by the storage component 8, it will not damage the roots of the seedlings. In case of damage or root burn, when the protruding profile of the cam 704 is no longer in contact with the piston rod 602, the deformation force of the stainless steel spring 603 can push the piston rod 602 to reset, so that a negative pressure can be generated in the liquid inlet cylinder 601, and the liquid inlet cylinder 601 can draw the mixed fertilizer inside the liquid storage tank 801 through the liquid inlet one-way valve 806 and the liquid inlet pipe 805. During the overall movement, the two soil covering shovels 10 set on the first steel frame 1 can backfill the soil on both sides of the ditch, so that the soil covers the roots of the seedlings.

[0057] When the overall device is turned, the external traction equipment lifts the first steel frame 1 through the hydraulic device installed on it, leaving only the steering wheels 1106 in contact with the ground. Then, through the steering of the external traction equipment, the two steering wheels 1106 can follow the steering of the traction equipment, thereby realizing the turning of the overall device or the traction and removal after the work is completed.
