[0024] See also Figure 1-6, a root digging and mud swinging device for transplanting seedlings in farmland, comprising a base plate 1, a movable wheel fixed at the bottom of the base plate 1, the movable wheel selecting an overall height of 8cm-15cm, an L-shaped frame 2 and a lifting hydraulic cylinder 14 fixed to the top of the base plate 1, a mounting frame 3 fixed to the top of the lifting hydraulic cylinder 14, a driving structure provided on the surface of the mounting frame 3, a driven cylinder 5 provided on one side of the mounting frame 3, a pneumatic clamp 6 fixed to the bottom of the driven cylinder 5, two transplant shells 7 fixed on the surface of the pneumatic clamp 6, a digging tooth 8 fixed to the bottom of the transplant shell 7, a pushing hydraulic cylinder 9 fixed to the surface of the L-shaped frame 2, a shock-absorbing block 10 fixed to one end of the pushing hydraulic cylinder 9, a combination frame 11 fixed to the surface of the shock-absorbing block 10, a vibration motor 13 fixed to the bottom of the combination frame 11, a filter screen 12 detachably provided on the top of the combination frame 11, a rectangular groove provided on the surface of the base plate 1, the combination frame 11 is slidably connected to the surface of the L-shaped frame 2;

[0025] The device can be moved by the movable wheels at the bottom of the base plate 1, and since the height of the seedlings exposed to the ground is usually 2-3 cm, and the overall height of the movable wheels is 8-15 cm, the base plate 1 can move normally above the seedlings without coming into contact with the seedlings. When the device moves to the top of the seedlings, the pushing hydraulic cylinder 9 is first started to drive the combination frame 11 to move outward, so that the rectangular groove on the surface of the base plate 1 is unobstructed, and then the driven cylinder 5 is driven to rotate by the driving structure, so that the driven cylinder 5 can drive the transplant shell 7 and the digging teeth 8 to rotate together through the pneumatic clamping 6, and cooperate with the contraction of the lifting hydraulic cylinder 14 to make the transplant shell 7 rotate and move downward at the same time, so that the transplant shell 7 can pass through the rectangular groove and dig the soil through the digging teeth 8, so that the soil containing the seedlings can enter the inside of the transplant shells 7 on both sides. At this time, the pneumatic clamping 6 can be further contracted. The transplant shells 7 on both sides can move toward each other, thereby applying pressure on the soil to prevent a large amount of natural falling of the soil during the lifting process. Then the hydraulic cylinder 14 is lifted and the mounting frame 3 is moved upward, so that the transplant shell 7 can move to the top of the pushing hydraulic cylinder 9. Then the hydraulic cylinder 9 is pushed to retract, so that the combination frame 11 drives the filter screen 12 to move above the rectangular groove. At this time, the pneumatic clamp 6 can drive the transplant shells 7 on both sides to move in the opposite direction, so that the seedlings and soil inside the transplant shell 7 can fall into the surface of the filter screen 12 together. The vibration motor 13 is started to drive the combination frame 11 and the filter screen 12 to vibrate, and the shock-absorbing block 10 reduces the shock of the pushing hydraulic cylinder 9. During the vibration process, the soil on the surface of the seedlings falls off naturally, reducing the physical damage to the root system caused by human operation, and the soil particles will gradually fall through the pores of the filter screen 12, while the larger roots and seedlings will remain on the filter screen 12, thereby realizing the mud swinging treatment of the seedlings.

[0026] Furthermore, the surface drive structure of the mounting frame 3 includes a bearing seat 16, which is fixedly connected to the surface of the mounting frame 3. The driving rod 4 is fixed to the inner wall of the bearing seat 16. The driving motor 15 is fixed to the top of the mounting frame 3. The output shaft of the driving motor 15 passes through the mounting frame 3 and is fixedly connected to the top of the driving rod 4. The driving rod 4 is detachably connected to the bottom of the driven cylinder 5.

[0027] The bearing seat 16 can support the surface of the driving rod 4, and the driving motor 15 can drive the driving rod 4 to rotate when working, so that the driving rod 4 can drive the driven cylinder 5 to rotate, thereby ensuring that the digging teeth 8 can dig the soil.

[0028] Furthermore, a thread is provided below the surface of the driving rod 4, and a thread groove is provided on the inner wall of the driven cylinder 5. The driving rod 4 and the driven cylinder 5 are detachably connected through the thread, and the disassembly rotation direction of the driven cylinder 5 is opposite to the rotation direction of the driving rod 4;

[0029] Through this design, the operator can remove the driven cylinder 5 from the surface of the driving rod 4 by rotating it, which makes it easier to clean the inside of the transplant shell 7. The design that the disassembly rotation direction is opposite to the rotation direction of the driving rod 4 also avoids the situation where the driven cylinder 5 is automatically disassembled from the surface of the driving rod 4 when the driving rod 4 drives the transplant shell 7 to rotate and excavate.

[0030] Furthermore, a connection block 19 is fixed to the surface of the filter screen 12. Through holes are provided on the surfaces of the connection block 19 and the combination frame 11. The connection block 19 and the combination frame 11 are detachably connected through the through holes using bolts.

[0031] With this design, the operator can remove the bolts in the through holes, so that the filter screen 12 can be separated from the assembly frame 11, and the filter screen 12 can be disassembled, replaced and cleaned.

[0032] Furthermore, two support pads 18 are fixed on the top of the bottom plate 1. The support pads 18 are made of rubber. The tops of the support pads 18 are slidably connected to the surface of the combination frame 11.

[0033] The support pad 18 can provide support for the combination frame 11 , further improving the stability of the combination frame 11 . The support pad 18 made of rubber can also absorb vibrations, thereby further reducing the vibrations transmitted from the combination frame 11 to the base plate 1 .

[0034] Furthermore, a folded protective cloth 20 is fixed between the transplant shells 7 on both sides;

[0035] When the transplant shells 7 on both sides move in opposite directions, the folding protective cloth 20 can be stretched, and when the transplant shells 7 on both sides move toward each other, the folding protective cloth 20 can be folded again, which enables a shielding effect to be obtained between the transplant shells 7 on both sides, so that soil and seedlings can be excavated from the inside of the transplant shells 7 and during the rising process, the folding protective cloth 20 can block the soil in the area between the transplant shells 7 on both sides, reducing the amount of soil falling.

[0036] Furthermore, two guide rods 17 are fixed to the top of the base plate 1, the tops of the guide rods 17 are fixedly connected to the surface of the L-shaped frame 2, and the guide rods 17 slide through the mounting frame 3;

[0037] When the lifting hydraulic cylinder 14 drives the mounting frame 3 to move, the surface of the mounting frame 3 slides on the surface of the guide rod 17, which enables the mounting frame 3 to obtain a linear guidance effect, reduce deviation and improve movement accuracy.

[0038] Furthermore, the transplant shell 7 is made of stainless steel, and the digging teeth 8 are made of cemented carbide;

[0039] Stainless steel has good corrosion resistance and can be used for a long time in a humid and acidic environment without rusting. It is suitable for transplant shells 7 that need to bear soil. Cemented carbide has extremely high hardness and strong wear resistance. It is suitable for hard soil and rocky environments, making it easier for the digging teeth 8 to dig the soil.

[0040] Working principle: the driving motor 15 can drive the driven cylinder 5 to rotate through the driving rod 4, and cooperate with the contraction movement of the lifting hydraulic cylinder 14 to enable the transplant shell 7 to rotate and move downward at the same time, so that the transplant shell 7 can dig the soil through the digging teeth 8, so that the soil containing the seedlings can enter the inside of the transplant shells 7 on both sides, and then lift the hydraulic cylinder 14 to move the mounting frame 3 upward, and then push the hydraulic cylinder 9 to retract, and the pneumatic clamp 6 drives the transplant shells 7 on both sides to move in opposite directions, so that the seedlings and soil inside the transplant shells 7 can fall together onto the surface of the filter 12, and the vibration motor 13 starts to drive the combination frame 11 and the filter 12 to vibrate. During the vibration process, the soil on the surface of the seedlings falls off naturally, reducing the physical damage to the root system caused by human operation, and the soil particles will gradually fall through the pores of the filter 12, while the larger roots and seedlings will remain on the filter 12, thereby realizing the mud swinging treatment of the seedlings.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
