Detailed Description
The invention will be further described with reference to the accompanying drawings.
Fig. 1 is a general construction diagram of a transplanting machine, which includes a transplanting device adapted for transplanting crops to high-mobility soil, a rotary tillage device 6 disposed before the transplanting device, and a soil covering device 7 installed after the transplanting device. The rotary tillage device 6 is used for rotary tillage to soil, and the earthing device 7 is used for earthing the root of seedling after the seedling is planted in soil.
As shown in fig. 2, a transplanting device suitable for transplanting crops to high-fluidity soil comprises a transplanting mechanism 1, a seedling protection device 2 and a seedling supply device 3; the transplanting mechanism 1 comprises a rotating seat 12 and a transplanting needle 11 arranged on the rotating seat 12, and the specific structure of the transplanting mechanism 1 is consistent with the prior patent application of the applicant and is not described herein; the seedling protection device 2 comprises an elastic sheet 21; as shown in fig. 4, after the transplanting needle 11 takes a seedling from the seedling supply device 3, the end of the transplanting needle 11 moves against the elastic piece 21, and in the process that the end of the transplanting needle 11 moves against the elastic piece 21, the transplanting needle applies a force to the elastic piece 21, so that the elastic piece 21 is bent and deformed, and the elastic piece 21 can be tightly abutted against the end of the transplanting needle 11, so that the seedling taken by the transplanting needle 11 is prevented from falling from the transplanting needle 11; the seedling protection device 2 also comprises a hard seedling protection piece 22; as shown in fig. 3, the hard seedling protection member 22 has a U-shaped groove 221, and an opening of the U-shaped groove 221 faces rearward; when the elastic sheet 21 is not acted on, the lower end of the elastic sheet is separated from the bottom surface 22a of the U-shaped groove 221, at least when the end of the transplanting needle 11 moves to the lower end of the elastic sheet 21, the end of the transplanting needle 11 contacts with the bottom surface 22a of the U-shaped groove 221 (as shown in fig. 4 and 5), so that the end of the transplanting needle 11 moves against the bottom surface 22a of the U-shaped groove 221 after being separated from the lower end of the elastic sheet 21, as shown in fig. 6.
When transplanting operation is executed, the transplanting device suitable for transplanting crops in high-fluidity soil moves forwards and transplanting seedlings is carried out, the lower end of the hard seedling protection piece 22 is lower than the surface of a soil layer, the side walls 22b at two sides of the U-shaped groove 221 can keep the soil out of the U-shaped groove 221 (as shown in fig. 7), after the end parts of the transplanting needles 11 are separated from the lower end of the bottom surface 22a of the U-shaped groove 221, the roots of the transplanted seedlings are lower than the surface of the soil layer, thus, the seedlings can be smoothly transplanted into the soil for planting the soil with the quick closed planting seams after the sand soil is slotted, the problem that seedlings cannot be smoothly transplanted into the soil due to the blocking of the soil in the planting process is solved, when the hard seedling protection piece 22 leaves the transplanted seedlings, namely, the transplanted seedlings are separated from the U-shaped groove 221, the soil at two sides of the planting seams is reflowed, the planting seam part is backfilled, the roots of the seedlings are covered, and the effect of keeping the seedlings in a standing state is achieved.

The slitting wheel 4 slits the soil before and cuts off the straw, stubble and other substances in the soil, the expanding wheel 5 moves along the path of the slitting wheel 4, the hard seedling protection piece 22 is closely behind the expanding wheel 5, as shown in fig. 7, the expanding wheel 5 expands the slits before, the hard seedling protection piece 22 moves closely behind, the breaking difficulty of the hard seedling protection piece 22 can be reduced, and the straw, stubble and other substances in the drawing are cut off by the slitting wheel 4, so that the lower end of the hard seedling protection piece 22 cannot cause the problems of grass hanging, soil choking and the like.
Preferably, the seedling feeding device 3 includes a seedling rack 31 and a machine base 32, a seedling blanket is placed on the seedling rack 31, the seedling rack 31 can reciprocate relative to the machine base 32, so that the transplanting needles 11 can sequentially obtain seedlings on the seedling blanket; the structure and operation of the seedling feeding device 3 are the same as those of the prior art, and will not be described in further detail here.
The upper ends of the elastic pieces 21 and the upper ends of the hard seedling protection pieces 22 are fixed at the lower ends of the stand 32. The lower end of the stand 32 is provided with a seedling taking gap, and after the transplanting needle 11 takes seedlings from the seedling taking gap, the end of the transplanting needle moves against the elastic piece 21.
Preferably, the elastic pieces 21 and the upper ends of the hard seedling protection pieces 22 are respectively provided with a first mounting hole 21a and a second mounting hole 22c which are arranged in a one-to-one correspondence manner; the corresponding first mounting hole 21a and the second mounting hole 22c are penetrated by the same screw screwed on the base 32. Thus, the hard seedling protection piece 22 can be conveniently added to the existing transplanting machine, and the improvement is convenient.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
