Embodiment Construction

[0019] The transplanting and seedling picking device of this embodiment is improved on the basis of the original seedling picking clip mechanism (for details, refer to Chinese patent documents with application numbers 201510244932.5 and 201510244983.8), and its structure is as follows figure 1 , 2 Shown, comprise the fork seat 3 that has jaw shape front fork 1 and rear fork 2. Between the front fork mouth 1 of the seedling fork seat 3, the longitudinal butt bolts 4 for adjusting the spacing of the forks are arranged. The back fork mouth 2 bottoms of seedling fork seat 3 has the extension seam 2-1 of band expansion arc bottom, and auxiliary seam adjustment bolt is housed in the extension seam 2-1. Therefore, 4 and 11 can be adjusted conveniently and reliably, and the purpose of adjusting the distance between the front ends of the up and down seedling-taking pins 9 can be achieved by changing the fork distance. The upper and lower sides of the seedling fork seat 3 have a pair ...

Abstract

The invention belongs to the technical field of agricultural and forestry machinery and relates to a transplantation seedling taking device. The transplantation seedling taking device comprises a seedling fork seat with a front fork opening and a rear fork opening, a longitudinal double-screw bolt used for adjusting a space of the fork opening is mounted in the front fork opening of the seedling fork seat, each of upper and lower sides of the seedling fork seat is provided with a pair of seedling fork handles, the front end of each seedling fork handle is connected with the front end of the seedling fork seat to form a clamping seam with a backward opening, and an elastic part is mounted at the rear end of each clamping seam. Seedling taking insertion needles extending forwards are fixed to the seedling fork handles respectively, a transverse double-screw bolt used for adjusting openness of the seedling fork handles is mounted between every two adjacent seedling fork handles, each seedling taking insertion needle and a corresponding penetration hole of an opening-closing plate form a moving pair, the opening-closing plate is connected with a cylinder piston rod fixed to the top surface of the upper seedling fork handle, and an inclination angle is formed between the axis of each penetration hole and the horizontal plane. By the transplantation seedling taking device, reliability in clamping of plug seedlings can be guaranteed, and the seedlings are protected from damages since an acting force in clamping is still transmitted through the seedling taking insertion needles which are elastic to some extent. In addition, a transplanting machine with the transplantation seedling taking device is efficient and stable in operation.

Description

technical field [0001] The invention relates to a device for picking seedlings from a hole in a seedling tray, in particular to a device for transplanting and picking seedlings, and belongs to the technical field of agricultural and forestry machinery. Background technique [0002] As far as the applicant knows, the existing vegetable transplanting machines all need to manually take the seedlings and then feed the seedlings. For example, in the technical solutions disclosed in Chinese patents with publication numbers CN204119785U and CN204217400U, the vegetable transplanting machines are semi-automatically operated and need to be completed manually. Taking seedlings and feeding seedlings is not only labor-intensive, but also has extremely low transplanting efficiency. In addition, rising labor costs have led to an increase in vegetable production costs. Since seedling picking not only needs to complete shifting and picking, the action is complex, but also requires strong ad...
