[0013] Compared with the prior art, the beneficial effects of the present invention are: The user pulls this device through the traction drive device to perform automatic film mulching and transplanting operations. After the user moves this device to the field, the user rotates the movable plate so that it rotates 90 degrees. At this time, the user can put the decomposable plastic film on the surface of the mounting rod, and then reset the movable plate. At this time, one end of the mounting rod is inside the movable plate, and is limited and supported by the movable plate. The second double-shaft motor controls two groups of threaded rods to control the movement of the moving block and the movable clamping plate. When the inclined surface at the bottom end of the movable clamping plate abuts against the inclined surface of the inclined surface receiving groove, at this time, while the movable clamping plate moves horizontally, it also moves upward, so that the decomposable plastic film can be centered and clamped by the movable clamping plate, which is very convenient for the user to use.

Subsequently, the user controls the second hydraulic rod to extend, so that the height of the pressing wheels at both ends of the first fixing plate is lower than the height of the other two groups of pressing wheels, so that the pressing wheels can bury and press the decomposed film, which is convenient for subsequent transplanting and warming, and improves the survival rate of the seedlings. The user fills one side of the seedling plate with seedlings. When the traction drive device pulls the first fixing plate and the seedling plate forward, the first motor and the first double-shaft motor are started. The first motor drives the reciprocating screw rod to rotate. Through the rotating reciprocating screw rod, the reciprocating sleeve and the seedling plate can perform continuous reciprocating movements, so that when transplanting, the seedlings can be evenly taken away. The movement of the seedling plate can be limited and supported by two groups of sliders. The seedling plate makes continuous reciprocating movements on one side of the first fixing plate and the baffle. At the same time, the output end of the first double-shaft motor drives the first rotating member to rotate through the extension rod. The first rotating member drives the second rotating member and a group of rotating rods to rotate through the transmission belt. Through a group of rotating rods, the rotating arm can be driven to perform a circular motion. The rotating arm drives the middle part of the reciprocating arm to perform a circular motion. One end of the reciprocating arm is limited by the rocker arm and another group of rotating rods. At the same time, one end of the reciprocating arm drives one end of the rocker arm to perform an arc-shaped reciprocating motion. At this time, the other end of the reciprocating arm drives the seedling claw to perform continuous reciprocating seedling taking and transplanting operations, so that the seedlings can be inserted into the field through the decomposed film, which is convenient for the user's transplanting work. After use, the user rotates the threaded locking rod and removes it, and then rotates the seedling claw into the receiving groove. Then rotate the threaded locking rod into the internal thread of another locking threaded hole. At this time, the fixing is completed. The user can also select the required seedling claw, unfold it, and then transplant the seedlings at the required position. At the same time, it can also cover the decomposable plastic film in a suitable manner. This device is not only convenient for users to use, but also can improve the film mulching effect. At the same time, it can also select a suitable transplanting position according to the user's needs, improve the applicability of this device, and can automatically center and clamp the decomposable plastic film, which further facilitates the user's work.

At this time, the fixation is completed, reducing the workload of the user; Please refer to Figure 8 and Figure 9, in this embodiment, the fixed film placing mechanism includes a second fixing plate 30. One end of a set of connecting frames 4 is fixedly connected to the second fixing plate 30, and the other end of the set of connecting frames 4 is fixedly connected to a limiting plate 41. One end of the limiting plate 41 is connected to a movable plate 32 through a rotating shaft. The bottom end of the second fixing plate 30 is connected to an installation rod 31 through a bearing, and one end of the installation rod 31 is rotatably connected to the bottom end of the movable plate 32. A decomposable ground film 40 is sleeved on the surface of the installation rod 31. A moving groove 33 is opened inside the installation rod 31.

The threaded rods 36 drive the moving blocks 34 and the movable clamping plates 39 to move. When the slope at the bottom end of the movable clamping plate 39 abuts against the slope of the slope receiving groove 37, the movable clamping plate 39 slides inside the moving block 34, so that the top end of the movable clamping plate 39 protrudes. At this time, the movable clamping plate 39 moves upward while moving horizontally, so that the decomposable ground film 40 can be centered and clamped by the movable clamping plate 39, which is very convenient for the user to use. At the same time, the moving block 34 and the movable clamping plate 39 can also center and clamp the decomposable ground film 40 of different sizes, thereby increasing the applicability of the device and facilitating the user to automatically center and fix the decomposable ground film 40, and being able to adapt to the decomposable ground film 40 of different sizes; Please refer to Figure 4, in this embodiment, the bottom end of the first fixing plate 2 is evenly connected with downward pressure arms 42 through a rotating shaft, the bottom ends of the downward pressure arms 42 are all connected with pressing wheels 43 through bearings, the bottom end of the first fixing plate 2 is connected with a second hydraulic rod 44 through a rotating shaft, and the output end of the second hydraulic rod 44 is connected with the middle part of the downward pressure arm 42 through a rotating shaft. The control ends of the second double-shaft motor 35 and the second hydraulic rod 44 are both electrically connected to the traction driving device 1. The user passes one end of the decomposable ground film 40 through the bottom ends of the first fixing plate 2 and the seedling plate 3 so that it is on one side of the bracket 13. Then the user controls the second hydraulic rod 44 to extend. The output end of the second hydraulic rod 44 drives the bottom end of the downward pressure arm 42 to move downward. At this time, the downward pressure arm 42 makes a circular motion. By controlling the elongation amounts of the second hydraulic rods 44 on both sides and the two groups of second hydraulic rods 44 in the middle, the height of the pressing wheels 43 at both ends of the first fixing plate 2 can be made lower than the height of the other two groups of pressing wheels 43, so that the pressing wheels 43 can bury and press the decomposable film, facilitating subsequent rice transplanting and heat preservation, improving the survival rate of the seedlings, and facilitating the burying and pressing work of the decomposable ground film 40; It should be noted that the control end of the first hydraulic rod 6 is electrically connected to the traction driving device 1 to facilitate the operation of this device. The control end of the first motor 10 is electrically connected to the traction driving device 1 to facilitate the operation of this device. The lengths of the two groups of extension rods 20 are different. One group of first rotating parts 22 is located on the surface of the longer group of extension rods 20, and one group of first rotating parts 22 is located on the surface of the shorter group of extension rods 20. One group of locking threaded holes 27 is located on the center line of the reciprocating arm 18. The included angles between the two groups of locking threaded holes 27 and the connection between the reciprocating arm 18 and the seedling claw 26 are both 120 degrees.

One end of the slope receiving groove 37 is in a slope shape adapted to the bottom end of the movable clamping plate 39, which can automatically retract and push out the movable clamping plate 39.

[0018] The user pulls this device through the traction drive device 1 to perform automatic film mulching and rice transplanting operations. After the user moves this device to the field, the user rotates the movable plate 32 by 90 degrees, so that one end of the mounting rod 31 is no longer inside the movable plate 32. At this time, the user can put the decomposable ground film 40 on the surface of the mounting rod 31, and then reset the movable plate 32. At this time, one end of the mounting rod 31 is inside the movable plate 32, and is limited and supported by the movable plate 32. The user then controls the second biaxial motor 35 to work. Driven by the second biaxial motor 35, two groups of threaded rods 36 rotate, and the threaded rods 36 drive the moving blocks 34 and the movable clamping plates 39 to move. When the inclined surface at the bottom of the movable clamping plate 39 abuts against the inclined surface of the inclined surface receiving groove 37, the movable clamping plate 39 slides inside the moving block 34, so that the top end of the movable clamping plate 39 protrudes. At this time, the movable clamping plate 39 moves upward while moving horizontally, so that the decomposable ground film 40 can be centered and clamped by the movable clamping plate 39, which is very convenient for the user. At the same time, the moving block 34 and the movable clamping plate 39 can also center and clamp the decomposable ground film 40 of different sizes, thereby increasing the applicability of this device. The user passes one end of the decomposable ground film 40 through the bottom ends of the first fixing plate 2 and the seedling plate 3, so that it is on one side of the support 13, and then controls the output end of the first hydraulic rod 6 to extend and retract. At this time, the output end of the first hydraulic rod 6 drives the first fixing plate 2 and the seedling plate 3 to move downward. At the same time, the first fixing plate 2 drives the guide rod 5 to slide at one end of the connecting frame 4, so as to be able to guide the movement of the first fixing plate 2. The height of the first fixing plate 2, the seedling plate 3 and the support 13 can be controlled by the first hydraulic rod 6 to make them in a suitable rice transplanting position. Then the user controls the second hydraulic rod 44 to extend. The output end of the second hydraulic rod 44 drives the bottom end of the pressing arm 42 to move downward. At this time, the pressing arm 42 makes a circular motion. By controlling the extension amounts of the two second hydraulic rods 44 on both sides and the two second hydraulic rods 44 in the middle, the height of the pressing wheels 43 at both ends of the first fixing plate 2 can be made lower than the height of the other two pressing wheels 43, so that the pressing wheels 43 can bury and press the decomposed film, so as to facilitate subsequent rice transplanting and warming and improve the survival rate of the seedlings. The user fills one side of the seedling plate 3 with seedlings. When the traction drive device 1 pulls the first fixing plate 2 and the seedling plate 3 forward, the first motor 10 and the first biaxial motor 19 are started at the same time. The first motor 10 drives the reciprocating lead screw 45 to rotate. Under the action of the rotating reciprocating lead screw 45 and the reciprocating sleeve 9 in the middle of the seedling plate 3, the seedling plate 3 and the slider 7 can make continuous reciprocating motions, so that when transplanting rice, the seedlings can be evenly taken away. The two sliders 7 can limit and support the movement of the seedling plate 3. The seedling plate 3 makes continuous reciprocating motions on one side of the first fixing plate 2 and the baffle 11. At the same time, the output end of the first biaxial motor 19 drives the first rotating part 22 to rotate through the extension rod 20. The first rotating part 22 drives the second rotating part 23 and a group of rotating rods 15 to rotate through the transmission belt 24.A set of rotating rods 15 can drive the rotating arm 17 to perform circular motion. The rotating arm 17 drives the middle part of the reciprocating arm 18 to perform circular motion. One end of the reciprocating arm 18 is limited by the rocker arm 16 and another set of rods 15. At the same time, one end of the reciprocating arm 18 drives one end of the rocker arm 16 to perform arc-shaped reciprocating motion. At this time, the other end of the reciprocating arm 18 drives the seedling claw 26 to perform continuous reciprocating seedling taking and transplanting work, so that the seedlings can be inserted into the field through the decomposition film, thereby facilitating the user's transplanting work.
