Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1-2, the hydraulically driven fully automatic transplanting combined working machine includes a rotary tillage system 1, a transplanting system 2, and a soil covering system 5 arranged in sequence; it also includes a profiling system 3 and a power system 4 .

As shown in Figs. 4-5, the rotary tillage system 1 includes a front frame 11, a rotary tiller 12 and leveling gap rollers 13 are arranged in sequence on the front frame 11, and the front frame 11 is also installed with a splitter Groove device 14 . The rotary tillage device 12 includes a rotary tiller roller 121 for performing rotary tillage treatment on the ground to crush the soil, and also includes a cover body for covering the rotary tiller roller 121 therein, and the cover body plays the role of gathering soil , so as to prevent the soil thrown out by the rotary tiller roller 121 from splashing out.

The trenching device 14 includes a trenching shovel 141 placed on the rear side of the rotary tiller roller 121, and the trenching blade 141 is centrally arranged relative to the rotary tiller roller 121, so that the trencher 141 can be opened in the middle of the working width of the combined working machine. ditch.

The front side of the upper end of the trenching shovel 141 is rotatably installed relative to the front frame 11, and the trenching device 14 further includes a compression spring 142 that acts on the rear side of the upper end of the trenching shovel 141 and exerts a downward pressure on the trenching shovel 141. When encountering a hard object, the trenching blade 141 can rotate backward and is buffered by the compression spring 142 to protect the trenching blade 141 .

The slitting roller 13 for leveling soil can be rotated actively, and includes a main roller body 131 , and a plurality of slitting discs 132 are distributed and installed in the axial direction of the main roller body 131 ; The main roller body 131 is used for compacting the land after rotary tillage, so that the land is leveled, and the seam opening plate 132 can open a planting seam on the land for planting seedlings. In addition, a pair of groove wall compaction discs 133 are fixed in the middle of the main roller body 131; the opposite surfaces of the two groove wall compaction discs 133 are planes, and the faces facing away from the two are conical surfaces, and the two groove wall compaction discs The two opposite planes on the 133 are respectively abutted on the two sides of the rear end of the trenching shovel 141, so that after the trenching shovel 141 is trenched, the conical surface of the trench wall compaction disc 133 acts on the trench wall, compacting and leveling the trench wall , so that the ditch wall is firm and not easy to deform and collapse.

Preferably, the rotary tillage system 1 further includes a gear lever group 18 installed on the rear side of the rotary tiller blade roller 121 , and the gear lever group 18 is composed of a plurality of gear levers distributed in the left-right direction. The above-mentioned cover body is composed of a top cover body 122, a front baffle 123 and a rear baffle 124. The rotary tiller roller 121 consists of a mounting roller 121a and a rotary tiller 121b that are scattered on the mounting roller 121a; The knife roller 121 rotates in the reverse direction, throwing the soil upwards and backwards. During the throwing process, the large pieces of soil and straw are blocked and dropped when they meet the blocking rod group 18, and the finely divided soil passes through the blocking rod group 18 and meets the rear blocking rod. Plate 124 is then dropped. The top cover 122 and the front baffle 123 are both made of steel plates, and the front baffle 123 can be adjusted in position relative to the top cover 122, so that the height of the lower end of the front baffle 123 can be adjusted according to the properties of the soil The height of the lower end of the front baffle 123 can effectively prevent the soil from leaking from the front side gap. The above-mentioned rear baffle 124 is flexible, and a steel bar 125 is fixed at the lower end thereof. In this way, the rear baffle 124 can adapt to the dynamic change of the amount of soil dumped for self-adaptive adjustment. After the rotary tillage, the volume is doubled, and the traditional rotary tillage device is difficult to adapt to this kind of soil. By setting the rear baffle 124 to be flexible and setting the steel bar 125 at the lower end thereof, a large amount of soil can be buffered after encountering the rear baffle 124. After landing, and due to the existence of the steel bars 125, after the rear baffle 124 is impacted, the middle and upper parts become arc-shaped, while the lower part is in a suspended state. In contrast, the solution in which the hard baffle is rotatably installed on the rear side of the top cover body 122 is subjected to a large amount of soil impact under the same conditions, and the bottom rises at a higher height and soil leaks out. In addition, the steel bar 125 can also play the effect of leveling the soil, and pre-levelling the soil after rotary tillage.
