The first is the conveyor belt type, which requires someone to sit on the equipment behind the tractor to place the seedlings one by one. The movement is very slow, and if it moves a little faster, the workers' hands cannot keep up; the second is the rice transplanting type, which is mainly imported from Japan. It requires people to follow the machine and place the seedlings while walking. The price is more than tens of thousands, and the efficiency is low, which cannot adapt to the actual production of the contract farmers; the third is the European and American imported and domestically imitated ones with a relatively high degree of automation.

[0027] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0028] like Figures 1-6 As shown, a seedling transplanting weaving machine provided by this embodiment includes a first mounting platform 1 and a second mounting platform 4, fixed rails 2 are symmetrically mounted on both sides of the top of the first mounting platform 1, a weaving mechanism 9 is arranged on the outer wall of the fixed rail 2, a feeding mechanism 5 is arranged on the top of the second mounting platform 4, a clamping mechanism 6 is slidably arranged on the feeding mechanism 5, and a unloading mechanism 7 is arranged just above the clamping mechanism 6; a transmission assembly 203 is rotatably mounted in the inner wall interlayer of the fixed rail 2, a first stepper motor 201 is mounted on one end of the transmission assembly 203, a driving shaft 202 is mounted on the other end of the transmission assembly 203, a supporting sleeve 205 is sleeved on the outer periphery of the driving shaft 202, and the supporting sleeve 205 is fixed to the outer wall of the fixed rail 2 by bolts through a fixing seat 204; the weaving mechanism 9 includes The outer end of the driving shaft 202 is fixedly connected to a turntable 901, and three groups of fixed shaft seats 904 are fixed through the turntable 901, one group of fixed shaft seats 904 is used to fix the driving shaft 202, and the other two groups of fixed shaft seats 904 are equipped with a winding worm 907 through bearing limit rotation. A planetary gear 906 is also nested and fixed on the winding worm 907, and one side of the planetary gear 906 is engaged with a central gear 908 that is fixed and rotated with the outer end of the support sleeve 205; the feeding mechanism 5 includes a track groove 502 fixed on the second mounting platform 4, and a screw rod 503 is rotatably connected in the track groove 502, and a slider 605 is provided on the screw rod 503 through a thread, and the outer end of the screw rod 503 is cooperated with the second stepping motor 501 fixed on the second mounting platform 4.

[0029] In the above embodiment, the fixed rail 2 and the weaving mechanism 9 can be flexibly disassembled and installed, and the weaving mechanism 9 can be flexibly disassembled and installed in combination, which is convenient for carrying. Before use, according to the weaving method of the seedlings (single-wire weaving or double-wire weaving), one or two sets of weaving mechanisms 9 are selected for installation and use. At the same time, the second mounting platform 4 and the unloading mechanism 7 are also adjusted in position according to the installation method of the weaving mechanism 9, so that the feeding mechanism 5, the clamping mechanism 6 and the unloading clamping plate 703 can be conveniently fed to the seedlings.

[0030] The first stepper motor 201 drives the turntable 901 to rotate 5 circles and then stops. At this time, the winding worm 907 also pulls out the braided rope on the bobbin 903 to a fixed length, and implements staggered braiding in front of the turntable 901. During the shutdown interval of the first stepper motor 201, the second stepper motor 501, the third stepper motor 601 and the fourth stepper motor 701 work in sequence.

[0031] The first function of the support sleeve 205 is to support the drive shaft 202 so that it can stably support the transmission assembly 203 to drive the turntable 901 to rotate smoothly. The second function is to support the center gear 908 installed on the external end. There is a gap between the center gear 908 and the turntable 901, and there is also a gap between the planetary gear 906 and the turntable 901. When the planetary gear 906 rotates, the central winding worm 907 serves as the support shaft and rotates synchronously.

[0032] The clamping mechanism 6 includes a sleeve 602 fixedly mounted on the top of the slider 605 and a third stepper motor 601. A support rod 603 is detachably mounted on the output end of the third stepper motor 601. The support rod 603 is rotatably connected to the sleeve 602. A V-shaped clamp 604 is fixedly nested at one end of the outer side of the support rod 603.

[0033] In the above embodiment, the V-shaped clamp 604 is pushed into the weaving mechanism 9 by the support rod 603. After being flipped over, the flexibly placed seedlings inside are put into the weaving rope group of the weaving mechanism 9. The weaving rope group is composed of 4 ropes, and the seedlings are placed across 2 groups of ropes, and then are staggered and woven and clamped.

[0034] The unloading mechanism 7 includes a conveyor belt 702, on the outer side of which a fourth stepper motor 701 is mounted. A discharge splint 703 is fixed to the top of the conveyor belt 702 by screws. The discharge splint 703 is used to limit the seedlings.

[0035] A controller 3 is provided on the back wall of the first mounting platform 1. The controller 3 is used to control the start and stop of the first stepper motor 201, the second stepper motor 501, the third stepper motor 601 and the fourth stepper motor 701. The controller 3 has a built-in PLC control program, which can control the five groups of stepper motors to work according to the set timing. Among them, the first stepper motor 201 is two groups of identical stepper motors, which automatically run the program after starting. The second stepper motor 501 drives the lead screw 503 to rotate to achieve linear reciprocating motion. The third stepper motor 601 drives the support rod 603 to achieve 180-degree flipping motion in both directions.

[0036] A rotating shaft 14 is symmetrically installed inside the first mounting platform 1, and a rotating seat 15 is welded on the top of the rotating shaft 14. The rotating seat 15 and the fixed track 2 are detachable and mounted. A worm gear 13 is nested and fixed at the bottom of the rotating shaft 14. A forward and reverse worm 11 is engaged on one side of the worm gear 13. The forward and reverse worm 11 are connected for synchronous rotation through a connecting disk 12. The forward and reverse worm 11 extends to one end outside the first mounting platform 1 and is equipped with an adjusting handwheel 10. The two worms of the forward and reverse worm 11 are set to have opposite teeth. When the two rotate in the same direction, they can engage and drive the worm gear 13 to rotate in the opposite direction, thereby driving the top mechanism to rotate synchronously in the opposite or reverse direction, thereby achieving the purpose of synchronously adjusting the angle.

[0037] A U-shaped wire rack 902 is symmetrically fixed to one side of the outer wall of the turntable 901 by bolts, and a wire drum 903 is movably installed on the U-shaped wire rack 902. A braided rope is wound around the wire drum 903, and the braided rope is slidably connected to the inner wall of the threading tube 905 that passes through the turntable 901. There are four groups of threading tubes 905. The thread head of the wire drum 903 is exerted with external force by the rotating winding worm 907, and the wire drum rotates to produce the wire by itself.

[0038] A material receiving frame 8 is provided at the front bottom of the weaving mechanism 9, and the material receiving frame 8 is used for receiving and placing the woven seedlings.

[0039] Working principle of this device: When the device is in use, it is connected to an external power supply, and the controller 3 is used to control the operation of the stepper motor on the device. By embedding the PLC control program, the orderly start and stop of the stepper motor can be achieved.

[0040] According to the width of the seedlings to be woven, the angle between the two sets of fixed rails 2 is adjusted so that the width of the wires output by the two sets of weaving mechanisms 9 can be woven at the appropriate position on the outer wall of the seedlings. The specific operation is: rotating the adjustment handwheel 10 drives the forward and reverse worm gears 11 to rotate synchronously, and the forward and reverse worm gears 11 drive the worm gear 13 engaged on one side, and the worm gear 13 drives the rotating shaft 14 and the rotating seat 15 connected at the top to rotate, thereby achieving the purpose of synchronously adjusting the angle between the two sets of fixed rails 2 and keeping them stable.

[0041] The controller 3 starts the first stepper motor 201, the second stepper motor 501, the third stepper motor 601, and the fourth stepper motor 701 to start working at the same time. The first stepper motor 201 drives the drive shaft 202 to rotate 5 circles through the transmission component 203 and then stops. The turntable 901 connected to the drive shaft 202 also rotates 5 circles. The turntable 901 drives the planetary gear 906 to rotate around the central gear 908, and at the same time engages and drives the planetary gear 906 to rotate. The winding in the planetary gear 906 The worm gear 907 rotates synchronously with the planetary gear 906. When one group of bobbins 903 rotates following the turntable 901, the end of the braided rope passes through the threading tube 905 and is wrapped around the tooth gap of the winding worm gear 907. As the winding worm gear 907 rotates, a pulling force is applied to the braided rope, causing it to be continuously discharged from the bobbin 903 and led out by another group of wire tubes. Similarly, the braided ropes of another group of bobbins 903 are led out from the threading tube 905 in parallel with the braided ropes of the above-mentioned bobbins 903 and intertwined together.

[0042] When the turntable 901 stops, the interwoven thread groups are in a vertical state, and the two thread groups form a rope buckle window near one end of the turntable 901. The second stepper motor 501 in the feeding mechanism 5 drives the screw rod 503 to rotate, and moves the slider 605 parallel to the track groove 502. The V-shaped clamp 604 in the clamping mechanism 6 carries the internal seedlings through the rope buckle window, and the seedlings span the center of the rope buckle windows of the two groups of weaving mechanisms 9. The third stepper motor 601 rotates the support rod 603, and the V-shaped clamp 604 puts down the seedlings. The front and tail ends of the seedlings are placed across the rope at the bottom of the rope buckle window. The feeding mechanism 5 resets the clamping mechanism 6, and the turntable 901 restarts to rotate. As the four braided ropes are intertwined and woven, the seedlings are woven and fixed. As new seedlings are continuously woven in the subsequent sequence, the seedlings are collected and stored in the receiving frame 8 at the bottom.

[0043] Among them, after the V-shaped clamp 604 is reset to the initial position, the seedlings are continuously fed into the unloading mechanism 7 manually, and the seedlings are flexibly placed in the unloading clamp 703. They are transported by the conveyor belt 702 and the fourth stepper motor 701 and fall into the V-shaped clamp 604 at the output end, realizing automatic loading and unloading.

[0044] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
