Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

Referring to fig. 1, an embodiment of the present invention provides a seedbed suitable for transplanting crop seedlings, including a support 1, a seedbed body 2 fixed on the support 1, a bottom support 3 disposed at the bottom of the seedbed body 2, and a lifting device for driving the bottom support 3 to be attached to or separated from the seedbed body 2; referring to fig. 3, a plurality of seedling holes 21 are arrayed in the seedbed body 2, and the seedling holes 21 are through holes which are vertically through.

The bottom support 3 comprises a first surface 31 and a second surface 32 which are oppositely arranged, and the second surface 32 is provided with protrusions 33 which correspond to the seedling holes 21 one by one and are matched with the seedling holes in size; the two ends of the shoe 3 are connected with the bracket 1 in a sliding way, and the first surface 31 and the second surface 32 of the shoe 3 can be overturned; when the first surface 31 is clung to the bottom of the seedbed body 2, the first surface 31 and the seedling holes 21 form a planting space with a closed bottom; when the second surface 32 is closely attached to the bottom of the seedbed body 2, the projections 33 are inserted into the seedling holes 21.

The bracket 1 is provided with a slide rail 11 and a slide block 12 sliding along the slide rail 11; the two ends of the bottom support 3 are rotatably connected with the sliding blocks 12 through connecting pieces 5.

The lifting device is a cylinder 4, the cylinder 4 is arranged at the left end and the right end below the bottom support 3, and the tail end of a piston rod of the cylinder 4 is fixedly connected with the sliding block 12.

Referring to fig. 2, the connecting member 5 includes an outer sleeve 51, an inner sleeve 52 fitted inside the outer sleeve 51 and rotatable with respect to the outer sleeve 51; the outer sleeve 51 is fixedly connected with the slide block 12, and the inner sleeve 52 is fixedly connected with the bottom support 3; bolt holes are vertically formed in the cylinder walls of the inner sleeve 52 and the outer sleeve 51, and bolts 53 are installed in the bolt holes. When the bolt 53 is removed, the inner sleeve 52 and the outer sleeve 51 can rotate relatively, so that the bottom support 3 can rotate around the axis of the inner sleeve 52; when either one of the first surface 31 or the second surface 32 is turned to be parallel to the plane of the bed body 2, the bolt 53 may be installed to lock the current position.

Referring to fig. 1, in an initial state, the first surface 31 of the shoe 3 is located above, the cylinder 4 is started, and the piston rod of the cylinder 4 pushes the slider 12 to move upward along the slide rail 11 of the bracket 1, so as to drive the shoe 3 to move upward; when the piston rod extends to the maximum stroke, the first surface 31 of the bottom support 3 is just tightly attached to the bottom of the seedbed body 2, as shown in fig. 4, a planting space with a closed bottom is formed between the first surface 31 and the seedling hole 21, and the planting space can be used for laying a culture medium and cutting the tissue culture seedlings in the culture medium for cultivation.

When the seedlings need to be transplanted after being cultivated for a period of time, the piston rod of the cylinder 4 is controlled to contract, so that the piston rod drives the slide block 12 to move downwards, and the bottom support 3 is driven to be separated from the seedbed body 2; when the shoe 3 has been lowered to the appropriate height, the lowering is stopped, the bolt 53 is removed, the shoe 3 is turned 180 degrees about the axis of the inner sleeve 52, as shown in figure 5, with the second surface 32 above, and the bolt 53 is then applied to lock the current position. Continuing to activate the air cylinder 4, extending the piston cylinder to push the bottom support 3 to move upwards, as shown in fig. 6, the second surface 32 is continuously close to the seedbed body 2, and the protrusions 33 on the second surface 32 extend into the bottom of the seeding holes 21; when the second surface 32 is tightly attached to the bottom of the seedbed body 2, the protrusions 33 completely extend into the seedling holes 21 and eject out the culture medium with the seedlings in the seedling holes 21, so that the separation of the seedlings from the seedbed is realized, and the seedling is convenient to fetch and transplant.

The conventional manual pressing seed taking is that the culture medium with the seedling plants are pressed out of the seedling holes 21 from top to bottom, the seedling holes 21 are required to be operated one by one in the mode, the efficiency is low, and the stems and leaves of the seedlings are easy to be broken and damaged by hands in the operation process; and the utility model discloses utilize the protruding 33 of elevating gear drive to take kind of seeds with seedling ejecting seedbed body 2 from bottom to top, can once accomplish to protruding 33 only contacts with culture basal portion, consequently gets kind of in-process and can not harm the seedling stem leaf, does not influence the survival rate of transplanting.

Referring to fig. 6, the thickness of the hole wall 22 of the seedling hole 21 is gradually increased from top to bottom, so that the upper end opening of the seedling hole 21 is larger than the lower end opening of the seedling hole 21, and the cross section of the seedling hole 21 is in an inverted trapezoid shape. Like this when collet 3 and seedbed body 2 separation, the seedling of taking the culture medium in seedling hole 21 can directly not fall from downthehole because of gravity to avoid causing the damage to its rhizome. Correspondingly, the size of the bulge 33 is matched with the size of the lower end opening of the seedling hole 21, so that the bulge can be smoothly ejected from the lower end of the seedling hole 21, and the separation of the seedling and the seedbed is realized.

In addition to changing the wall thickness of the hole wall 22, an inclined plate-like structure may be provided in the seedling hole 21 to achieve the purpose that the upper end opening of the seedling hole 21 is larger than the lower end opening.

The utility model provides a seedbed equipment except can being applicable to common cash crops for example watermelon seedling, cowpea seedling etc. also can be applicable to some crops that have special planting requirement, for example colored rice, special variety's rape or potato etc..

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims.
