Referring to fig. 6, the two swing arms 22 are connected to each other by a support frame 23 extending left and right, and the support frame 23 is disposed adjacent to the support shaft 11 of the frame 10.

Referring to fig. 7, the power device 14 of the transplanter includes a main transmission case 141, a second transmission shaft 142, a first bevel gear set 143, a second bevel gear set 144, and a rotation shaft 145, wherein the first transmission shaft 1410 of the main transmission case 141 extends left and right, the second transmission shaft 142 is located in the inner space of the swing arm 22 and extends in the front and rear direction, and the front end of the second transmission shaft 142 is in transmission fit with the end of the first transmission shaft 1410 through the first bevel gear set 143. The front wheels 21 are centrally mounted on a shaft 145, the shaft 145 being in driving engagement with the rear end of a second drive shaft 142 via a second bevel gear set 144. The second transmission shaft 142, the first bevel gear set 143, the second bevel gear set 144 and the rotation shaft 145 are provided with two sets corresponding to the two front wheels 21, and the output end of the first transmission shaft 1410 of the main transmission case 141 is connected to the two second transmission shafts 142, respectively.

Referring to fig. 3 and 5, the height of the entire frame 10 required during the transplanting operation and the transferring and walking process is different, for example, during the transferring process, the frame 10 should be lowered as much as possible in order to raise the frame 10 to a relatively high height position, and during the transplanting operation, the frame 10 needs to be lowered to meet the requirements of the ditching and transplanting operations, and therefore, a lifting mechanism is further provided between the frame 10 and the front wheels 21 in this embodiment to drive the frame 10 to lift relative to the center of the front wheels 21.

The lifting mechanism includes a drive mechanism 41, a carriage 43, and a swing frame 42.

The driving mechanism 41 of the present embodiment is provided on the frame 10, and has a power output end that reciprocates in a linear direction. Preferably, the driving mechanism 41 can adopt a cylinder, and the cylinder can be correspondingly matched with the power device 14 of the transplanter to share the same power system.

The frame 10 also has a slide slot 44, specifically, the slide slot 44 extends from the front to the back and upward. The sliding frame 43 is slidably disposed in the sliding groove 44, wherein the sliding frame 43 includes a first connecting plate 431 extending in a transverse direction at a front portion and a second connecting plate 432 connected to the first connecting plate 431, a middle portion of the first connecting plate 431 is connected to a piston rod of the cylinder, a front end of the second connecting plate 432 is connected to an end portion of the first connecting plate 431 extending to a side portion (left or right side), and a rear end thereof is rotatably connected to the swing frame 42. The swing frame 42 is a triangular frame structure, wherein one corner of the frame structure is pivotally connected to the support shaft 11 of the frame 10, the other two corners are designated as a first connection end 421 and a second connection end 422, the first connection end 421 is pivotally connected to the rear end of the second connection plate 432, and the second connection end 422 is fixedly connected to the support frame 23 disposed between the two swing arms 22. The extending direction of the cylinder is the same as the extending direction of the sliding groove 44, when the cylinder extends, the sliding frame 43 is driven to reciprocate along the sliding groove 44, and further the force is transmitted to the swing frame 42, because the second connecting end 422 of the swing frame 42 is fixedly connected with the supporting frame 23, when the cylinder extends backwards, the frame 10 can be lifted upwards relative to the center of the front wheel (the front wheel lands, and the reacting force thereof pushes the frame to rise). Conversely, when the cylinder is retracted, the frame 10 moves downward with respect to the center of the front wheel, and the overall height of the frame 10 is lowered.

In order to make the above-described elevating movement more stable, it is preferable that the swing frame 42 has two symmetrically disposed left and right, corresponding to the two front wheels 21, respectively. The two swing frames 42 are respectively connected to the swing arms 22 of the two front wheels 21, and are driven by the same drive mechanism 41. Specifically, there are two second connecting plates 432 of the carriage 43, one first connecting plate 431, and two second connecting plates 432 connected to the left and right ends of the first connecting plate 431, respectively. Therefore, when the oil cylinder is operated, the two swing frames 42 can be driven to operate at the same time, and the lifting adjustment process of the frame 10 relative to the front wheels 21 is more stable.

The ditching mechanism 13 of this embodiment adopts ripple disc type furrow opener, and the quantity of furrow opener is unanimous with the quantity of year seedling board, and both correspond in the front and back direction.

The soil covering wheel device is arranged at the rear part of the frame 10, in particular to the rear side of the furrow opener. The soil wheel means includes at least two sets of soil wheel assemblies 30, and six sets of soil wheel assemblies 30 are sequentially spaced in the left-right direction as shown in fig. 4, in accordance with the number of the furrow openers. Each set of soil covering wheel assemblies 30 comprises two first soil covering wheels 31 and two second soil covering wheels 32 which are arranged at intervals in the left-right direction and have opposite inclination directions, specifically, the first soil covering wheel 31 on the left side in each set of soil covering wheel assemblies 30 inclines from bottom to top to the left, and the second soil covering wheel 32 on the right side inclines from bottom to top to the right, namely, the bottoms of the first soil covering wheel 31 and the second soil covering wheel 32 are relatively close, namely, the gap between the first soil covering wheel 31 and the second soil covering wheel 32 is minimum at the bottommost position close to the ground, so that the soil can be rolled up to cover the root position of the seedling in place during the advancing process.

The frame 10 of this embodiment has a fixing frame 33 extending downward corresponding to each set of covering wheel assemblies 30, the lower end of the fixing frame 33 has a first connecting shaft 12 extending to the left and right, and the first covering wheel 31 and the second covering wheel 32 of each set of covering wheel assemblies 30 are rotatably connected to the left and right ends of the first connecting shaft 12, respectively. The fixing frame 33 has at least two connecting holes 330 formed at intervals in the vertical direction, so that bolts are inserted into the connecting holes 330 with a proper height to install the fixing frame or 33 on the frame 10, and the fixing frame 33 can adjust the height position of the covering wheel assembly 30 relative to the frame 10 according to different requirements.

The rear side of the chassis 10 also has a handle 18. When the transplanter is transferred, the user holds the handle 18 to slightly raise the rear of the frame 10 so that the soil covering wheel assembly 30 is disengaged from the ground, as shown in detail in fig. 5.

An important point of the present embodiment is that, during the transplanting operation of the transplanter, the frame 10 is supported by the soil covering wheel assemblies 30 and the two front wheels 21, i.e. the weight of the whole transplanter can act on the soil covering wheels, so as to play a role of compacting and covering soil, and ensure a good soil covering effect for the dry land transplanting operation. In the preferred scheme, the whole body is adjustable in position up and down relative to the center of the front wheel 21 under the driving of the lifting mechanism, so that the requirement of height adjustment of the frame 10 in the transplanting operation process and the transition walking process of the transplanter is met.
